    A load weighing device is provided to determine the magnitude of a load carried by a material handling device such as a lifting crane, hook block arrangement, or the like. The weighing device is designed to be incorporated into existing material handling apparatus and to accurately measure the magnitude of any load being handled by the apparatus while minimizing the likelihood of extraneous forces from introducing erroneous measurements (unrelated to the load) into the weighing system. In a first embodiment of the invention, the material handling apparatus includes a first structure for carrying a load, a second structure from which said first structure is suspended, with one of the structures including an elongated force-transmitting member having a longitudinal axis. A load member has a central portion which engages a portion of the force-transmitting member and the load member also has opposite end portions which engage the other of the structures. The load member is mounted such that the first structure applies a force thereto in proportion to the load in one direction to either the central portion or the end portions of the load member, while the second structue applies a force to the other of the central portion or the end portions. Means are provided for measuring the strain introduced into said load member due to the application of said forces applied thereto.

    专利说明:

    The invention relates to weighing equipment, namely, to an eco-discharge device, for example, to cranes. Ivesany devices containing an H-shaped structure, with glued on them strain gauges Clj. However, these devices have low measurement accuracy. The closest to the proposed technical entity is a device containing at least one axis of a pulley, which is affected by a weight load, with the ends of the axis of the pulley made leaning on the supporting structure associated with the horizontal force-bearing bar, and the supporting structure with a load sensor to determine the load C acting on the axis of the load; However, the known device has a low weighing accuracy since the H-shaped element connects the parallel stands designs in such a way that their movement relative to each other is possible. The purpose of the invention is to improve the accuracy of vzveshvani. This goal is achieved by the fact that in a scooping device containing at least one pulley axis, on which a weight load is acting, the ends of the pulley axis are made resting on the supporting structure connected to the horizontal buttruder bar, and supporting the design is made with a load sensor to determine the load acting on the axis of the implant; one part of the supporting structure includes two rod elements mounted parallel to each other and across the pulley axis lying on the central In these sections, the ends of these rods rest on another part of the supporting structure, which is connected to the force-beam, and mechanical elements are installed on both sides of their core sections to measure the shearing forces between the central points and the ends of these rods. rod elements FIG. 1 shows a tap for casting metal, ontal projection; in fig. 2 -, side view, in FIG. 3, the same, more general arrangement of the weighing device; . in fig. 4 shows section A-A in FIG. 3; in Fig. / 5 - VZ. The lashing device is RB14 type; in fig. 6 is a section BB in FIG. 5 in FIG. 7 - device, general view; in fig. 8 is a section bb of FIG. 5. The weighing device consists of a timber 1 with hooks 2 attached to it for suspending the ladle 3, into which the molten metal from the steel furnace enters. The ends of the beam 1 are connected to a pair of elongated force-transmitting elements in the form of axes 4. The latter pass into the groove of the hole 5 in the side plates b, which are fixedly fixed relative to the beam 1. The axes 4 rotationally carry a plurality of pulleys 7 which are provided with thrown through them cables 8. Pulleys 7 and dew 8 ow - are part of a stationary lifting device for lifting the bucket, and letting it go in any position. The core element 9 has, in each of the recesses 10 and above the axis 4, and has an elongated shape, each element 9 having a pair of voltage-sensitive sensors of mechanical stresses 11 on each side of each end of the element 9. The axis 4 has an end by removing a part of the axis, it can be either a horizontal upper surface or a concave upper surface 12 on which a bronze plate 13 lies, having a horizontal flat upper surface which is in contact with the core element 9, Medium The core element 9 has a groove which is filled with the plate 13. The tight connection of the core element 9 with the plate 13 minimizes the relative lateral movement to the axial line of the axis 4. However, the plate 13 and the core element 9 can slide relative to the axis 4 due to the tight contact of the plate 13 and surface 12 of axis 4. One end of axis 4 has a horizontal upper surface, and the other end has a bronze plate 13 with a curved lower and horizontal upper surface. Further, the plate 13 is designed with sufficient gaps from the vertical surfaces of the core element 9 so that it has some freedom of movement in a direction parallel to the axial line of the axis 4. The ends of each of the core elements 9 are attached to the corresponding side plate 6; Each end has recesses 14, and each recess accommodates one end of a finger 15, the other end of which enters recess 16 in block 17 attached to the side plate 6. Each such finger has a spherical shape 18 that serves to direct the forces acting on the side plates 6, generally running perpendicularly longitudinally to its neutral center line of the core member. In order to limit the maximum allowable movement of the H-shaped structure, there are locks 19 for the abutment (and in them opposite ends of the core element 9 and thus restricting the movement of the rod elements in the direction transverse to the axis 4, as well as stoppers such as screws 20 for abutting the side elements the sides of the rod members 9 and the end of the axis 4 to prevent excessive displacement of the I-shaped structure in the direction mainly parallel to the axis-line axis of the axis 4.
    The device works as follows. .
    The stoppers do not come into contact with the H-shaped structure, and the distance between them slightly exceeds the magnitude of the core element 9 so that only one stopper can be in contact at a time .g
    with the core element 9. Thus, the stoppers can not create in the core element 9 napse zhnny and bending. The beam of the plate b is suspended from 4 m and 4 that transmit load forces and contain a structure for holding the load lifted by the crane. Also, axis 4, prevents assembly elements transmitting forces to the central section of the core elements, this creates a stress in the core elements 9, which is captured as an indicator of the weight of the load held by the crane. Y
    Due to the free movement of the bronze plate in a direction parallel to the axial line of the axis, the likelihood of undesirable effects is reduced. contact surfaces, which improves weighing accuracy. Fiz. FIR
