description Background of the Invention The subject matter disclosed herein relates to turbines and, more particularly, to systems and methods for mounting balance weights within a turbine and components of a turbine. Some power plants, for example, certain nuclear power plants, gas turbine or combined cycle power plants, put in their designs and in operation turbines. Some of these turbines include rotating components and assemblies (e.g., a drum rotor, impeller, and impeller, etc.) which rotate during high-speed, close-tolerance operation within a housing of the turbine. Balancing of these components or assemblies (e.g., even weight distribution around a center of the rotor) may be required for efficient and safe operation, thereby reducing wear and vibration. Some systems may be out of balance due to production variations, material compositions, design solutions, component alignments, etc. In these systems, balance weights (e.g., rotor balance weights, trim balance weights, etc.) can be used to balance these unbalanced components after they are installed in the turbine housing / jacket. These balance weights may be attached to the turbine (e.g., on a wheel, shaft, etc.) by a technician during assembly, the position and size of these balance weights being selected to counteract a known imbalance in the system. In some systems, these balance weights are on the outer turbine wheels (e.g., where access is easy). However, mounting may be difficult even on the outer turbine wheels and / or restricted by plant design, since access to the outer turbine wheels requires working through small access openings that are covered by removable flaps. These small access openings are designed to avoid major disassembly for turbine maintenance by allowing only limited access to the internal parts of the turbine. However, the size of the access opening can complicate and limit maintenance operations with conventional tools where long reach and accurate handling is required for proper assembly. Brief Description of the Invention Disclosed are systems, methods and apparatus designed to facilitate the mounting of balance weights on a turbine. According to the invention, a device for mounting balance weights on rotating components in a turbine having an access opening comprises: a base part having a cavity and an engagement tip adapted to be connected to a balance weight; and an inner member disposed within the cavity of the base member having an inner tip at a first end, the inner tip configured to actuate a locking screw connected to the balance weight. According to the invention, a system for mounting balance weights (110) on rotating components (60) of a turbine (10) is provided, which comprises: a balance weight with a locking screw; a base member having a cavity and an engagement tip connected to the balance weight; and an inner member disposed within the cavity of the base member having an inner tip at a first end, the inner tip configured to actuate the locking screw.

Additionally or alternatively, the device comprises a first handle which is connected to an outer surface of the base part. The base part and the first handle may be formed so that they form a geometric shape whose dimensions are greater than the access opening of a turbine. The inner component is optionally rotatable within the cavity.

A superfluous explanation of these elements has been omitted for the sake of clarity. Finally, it will be understood that the components in FIGS. 1-7 and their associated descriptions are applicable to any embodiment described herein. Detailed Description of the Invention The systems, methods, and devices of the present invention are capable of increasing range and ease of assembly / balancing of a rotating subassembly (eg, mounting balance weights) in a turbine, thereby reducing vibration and operational efficiency and longevity of the turbine can be improved. The embodiments of the present invention include a device having an engagement tip adapted to be attached (e.g., screwed in) to a balance weight (e.g., via a counterbore). The apparatus allows a technician to handle and / or move the attached balance weight in a restricted access turbine (e.g., through an access port). The technician uses the device to position, adjust and fix the balance weight at a desired position (e.g., within a groove or slot of a turbine wheel). When the balance weight is fixed, the technician operates an inner tip of an inner member disposed in a cavity of the base member to actuate a position of a set screw in the balance weight while securing the balance weight in the turbine. In one embodiment, the inner member is rotated within the base member to move the balance weight lock screw toward the turbine. As the set screw extends, it contacts the turbine (e.g., upon reaching one surface of the groove bottom), thereby bringing the balance weight into contact with groove surfaces, pressing the balance weight against portions of the groove while securing the balance weight within the groove. In another embodiment, the locking screw is screwed into a matching thread in an opening defined in the turbine. The apparatus further includes a clamp member that clamps the set screw, the balance weight and / or the turbine wheel to secure the balance weight in the groove after the balance weight has been set at the desired location. In one embodiment, after the balance weight has been positioned and the set screw has been tightened, the clamping member clamps at least a portion of the following parts (eg, by driving into a surface of a component, thereby deforming and locally clamping the component and preventing rotation of the component ): the counterbalance weight set screw, the counterbalance counterbalance weight counterbalance, and / or a portion of the turbine against the counterbalance weight to prevent counterbalance weight from rotating. The device is then removed from the turbine by disengaging (e.g., unscrewing) the base from the counterbalancing weight and withdrawing the device from the turbine with the balance weight remaining in the desired position on the turbine. With reference to the figures, embodiments of systems, methods and apparatus are shown which are designed to increase the range of technicians and facilitate the mounting of balance weights on turbines. The components in the figures may each be connected by conventional means, e.g. by a bolt, a screw, a weld or other known means, as indicated in Figs. 1-7. Referring to the drawings, FIG. 1 shows a partial perspective sectional view of a gas or steam turbine 10. The turbine 10 includes a rotor 12 having a rotating shaft 14 and a plurality of spaced rotor wheels 18. A plurality of rotating blades 20 are each mechanically coupled to the rotor wheels 18. In particular, the blades 20 are arranged in rows which extend around the circumference of the rotor wheels 18, respectively. A plurality of fixed vanes 22 circumferentially extend around the shaft 14, and the vanes are located axially between adjacent rows of vanes 20. The fixed vanes 22 cooperate with the vanes 20 to form a step and form part of a gas flow furnace and / or or Damofstromofads defined by the turbine 10. In operation, gas or vapor 24 enters through an inlet 26 of the turbine 10 and is directed through the stationary vanes 22. The vanes 22 direct the gas or vapor 24 downstream against the vanes 20. Gas or vapor 24 flows through the remaining stages and exerts a force on the vanes 20 which causes the shaft 14 to rotate. At least one end of the turbine 10 may extend axially from the rotary shaft 14 and may be connected to a consumer or machine (not shown), such as, but not limited to, a generator and / or other turbine. In one embodiment, the turbine 10 includes five stages. The five stages are referred to as L0, L1, L2, L3 and L4. The stage L4 is the first stage and is the smallest (in the radial direction) of the five stages. Stage L3 is the second stage and is the next stage in the axial direction. Level L2 is the third level and is shown in the middle of the five levels. Stage L1 is the fourth and penultimate stage. The level LO is the last and (in the radial direction) largest stage. It should be understood that the five stages are shown by way of example only and each turbine may have more or less than five stages. As further described herein, the teachings of the invention do not require a multi-stage turbine. Referring to Figure 2, a partial sectional view of a portion of a turbine 50 (e.g., a gas turbine) according to embodiments is shown. The turbine 50 includes a rotating member 60 (e.g., an outer turbine wheel) connected to a rotor 56 of a turbine 50. During operation, the rotor 56 may rotate within the turbine 50 via a connection with a bearing 54. As discussed herein, unbalanced rotations of the rotor 56 and / or member 60 about a centerline 52 of the turbine 50 may create vibrations. In one embodiment, a technician access space 70 is defined between the bearing 54 and a shell 72 of the turbine 50, which partially defines a flow path 64 of the turbine 50. A technician access space 70 allows a technician to crawl within a portion of the turbine 50 to an inner turbine wall 58. The technician enters internal portions of the turbine 50 through an access opening 62 formed in the inner turbine wall 58. In one embodiment, the technician adjusts a balance weight 80 (shown in phantom) through the access opening 62 and / or connects to a component 60 (eg, by means of an in FIG 3 shown device 120). With particular reference to FIG. 3, a schematic block diagram of a portion of a system 100 having a balance weight 110 and a device 120 according to embodiments of the invention is shown. In this embodiment, the balance weight 110 defines a sink 114 configured to receive an engagement tip 124 on a base portion 122 of the device 120. During operation, the engagement tip 124 connects to the countersink 114 (eg, thread, bond, insert, etc.) thereby securing the balance weight 110 to the adjustment, handling and adjustment device 120 within the turbine 50 (shown in FIG. 2) , In one embodiment, the countersink 114 defines a thread that mates with a mating mating thread on the engagement tip 124. The threads on the engagement tip 124 and the countersink 114 are made as conventional threads (e.g., threads connecting two members by clockwise rotation) or counter threads (e.g., threads connecting two members by counterclockwise rotation). The base portion 122 includes a first handle 126 for adjusting the device 120 and balance weight 110 and a tether 170 provided to attach to an object (eg, a technician, instrument, etc.) and prevent the device 120 may fall into the turbine 50. In one embodiment, the first handle 126 and the base portion 122 are configured to form a geometric shape whose dimensions are greater than the access opening 62 (shown in FIG. 2) in the turbine 50 (eg, between a turbine shell and a rotor). the mold (eg, making it geometrically impossible) prevents the mold 120 from fitting into and / or inadvertently falling into parts and / or cavities of the turbine 50 (shown in FIG. 2). In one embodiment, the base member 122 includes a cavity 128 (e.g., defining a cylindrical tube / cavity) configured to receive an inner member 130 (shown in phantom). The inner member 130 rotates within the base member 122 and has an inner tip 132 that is configured to engage a portion of a locking screw 112 disposed in a counterbore 114 of the counterbalance 110. The inner tip 132 has a textured tip, a magnetic tip, a hexagon contour, a crescent contour, a cross-slot contour, or any known threaded fastener contour. In one embodiment, the inner member 130 is held in the cavity 128 via a linear bearing and a snap ring. The inner member 130 includes a threaded handle 138 located at one end of the inner member 130 substantially opposite the inner tip 132. In one embodiment, inserting the inner member 130 into the base member 122 includes using a keyway, groove, or similar alignment system to align the inner member 130 relative to the balance weight 110 and / or the counterbore 114. In another embodiment, the inner tip 132 a magnet and / or epoxy to connect and / or actuate the locking screw 112. In one embodiment, the base member 122 defines a slot 134 (shown in phantom) adapted to receive a clamping member (e.g., clamping member 200 in Fig. 4). In one embodiment, the slot 134 has a key slot. Referring to Figure 4, a schematic block diagram of a portion of a clamping member 200 according to embodiments of the invention is shown. In one embodiment, the clamping member 200 has a clamping nib 240 located at a first end 242 of the clamping member 200 opposite a third handle 248. The clamping member 200 has a shaft 244 that is adapted to be inserted into the cavity 128 of the base member 120 (shown in FIG. 3). During operation, the clamping member 200 is in one embodiment in the Locking screw 112 is driven (for example, by a moment), whereby the locking screw 112 is clamped on the balance weight 110 and / or the turbine wheel. In another embodiment, the clamping member 200 is driven into the counterweight 110 proximate the locking screw 112, thereby securing the locking screw 112 against rotation (e.g., dislodgement). In another embodiment, the clamping member 200 is driven into a portion of the turbine wheel closest to the balance weight 110 to prevent the balance weight 110 from rotating. In one embodiment, the nipping tip 240 is at the center of the nipping member 200. In another embodiment, the nipping tip 240 is radially the center of the nipping member 200. During operation, the nipping member 200 is inserted into the base member 120 and contacts the locking screw 112. In one embodiment, the clamping tip 240 is integrated in an inner member 130 (e.g., at an end opposite the inner tip 132). In another embodiment, the clamping tip 240 and the inner tip 132 are interchangeable heads / tips (e.g., socket set, tool set, etc.), thereby allowing the system 100 to be used for a variety of turbines for various functions. In one embodiment, inserting the clamp member 200 into the base member 122 includes the use of a keyway, groove, or similar alignment system configured to align the clamp member 200 relative to the set screw 112, the balance weight 110, and / or the sink 114. It will be appreciated that the operation of both the inner member 130 and the clamping member 200 may be manual, energetic, pneumatic, electrical, magnetic, hydraulic or any of the currently known or later developed actuating forms. With reference to FIG. 5, an illustrative process flow diagram according to embodiments of the invention is shown. In process P1, the balance weight 110 is connected to the apparatus 120 and prepared for handling and mounting in the turbine 50. This may be done by technicians or machines based on a scheduled or user-initiated assembly process and may include removing and / or releasing an outer shell of the turbine 50. Joining device 120 and balance weight 110 includes inserting and / or screwing an engagement tip 124 of base member 122 into countersink 114. Countersink 114 has threads that mate with threads on engagement tip 124, providing a secure and releasable fit Connection between the device 120 and the balance weight 110 is made possible. Following the process P1, the balance weight 110 is introduced into a portion of the turbine 50 in the process P2 and is handled and / or adjusted by a cavity within the turbine 50 by means of the apparatus 120. In particular, the balance weight 110 is brought into a mounting position by means of the device 120 (e.g., a groove, a slot above a turbine port for receiving the set screw 112, etc.). In one embodiment, the balance weight 110 is positioned within a groove in the turbine 50 such that the balance weight, prior to tightening the set screw 112, has clearance to circumferentially move around the groove, but is geometrically retained against direct stripping. Following process P2, in process P3, set screw 112 is actuated by inner member 130, thereby connecting set screw 112 and balance weight 110 to a component (eg, wheel, shaft, etc.) of turbine 110 and balance weight 110 on the turbine 50 (eg temporarily or permanently) is attached. In one embodiment, the inner tip 132 may be inserted into a portion of the set screw 112 such that by rotation of the inner member 130, the set screw 112 is threaded toward the turbine 50, whereby the set screw 112 contacts the turbine 50 and inserts the balance weight 110 into the /. the groove of the turbine 50 pushes / secures. In another embodiment, the inner tip 132 is inserted into a portion of the locking screw 112 such that the rotation of the inner member 130 causes the locking screw 112 to thread into a mating opening in the turbine 50. Subsequent to the process P3, the device 120 is released from the balance weight 110 and removed from the turbine 50 in one embodiment in the process P4. Alternatively, in the process P4, following the connection of the set screw 112 with the turbine 50, the inner member 130 is removed from the base portion 122 of the apparatus 120. In one embodiment, the base portion 122 remains connected to the balance weight 110. Subsequent to the process P4, the clamping member 200 is inserted into the base part 122 in the process P5. By inserting the clamping member 200 into the base part 122, the clamping tip 240 can be aligned with the locking screw 112. In another embodiment, the clamping tip 240 is radially aligned relative to the center of the locking screw 112. Subsequent to the process P5, in the process P6, the clamp member 200 contacts the balance weight 110 (eg, set screw 112) and sets the set screw 112, thereby holding the balance weight 110 in position within the groove, and serves as a balance weight support member 110 Embodiment this involves exerting a force on the clamping member 200, whereby the clamping tip 240 clamps and / or screws the locking screw 112 in a part of the turbine 50, thereby preventing rotation of the locking screw 112 and / or the release of the balance weight 110. In another embodiment, the clamping member 200 clamps the balance weight 110 and / or the turbine wheel. Subsequent to the process P6, the device 120 is detached from the balance weight 110 in the process P7 and removed from the turbine 50. The detachment of the device 120 may include unscrewing the engagement tip 124 of the base member 122 from the sink 114.
