    [0008] More particularly, the invention concerns a device for carrying out tensioning and loosening operations by shortening or lengthening a tensioning set of tie rods, in a fast and very simple way given the possibility of being operated by means of a pneumatic drive, preferably , although it can be activated if necessary, manually
    [0010] State of the art
    [0012] Container transport occurs mainly in a maritime service context and increasingly also in the land transport sector, due to its easy handling and the speed and efficiency of loading and unloading operations. Containers are used to transport bagged, packaged and unitized loads.
    [0014] Thus, during maritime transport there are frequent rocking of the vessels that can be of considerable magnitude and that can seriously affect the cargo, if it is not properly moored. Likewise, during the transport of land cargo, the container may be exposed to braking, acceleration, and vibrations that can affect the cargo, causing problems.
    [0016] Lashing or mooring is the task of fixing the loads on a ship or transport vehicle with the maximum possible safety so that during its movements the loads remain perfectly moored or lashed at a fixed point so that they arrive in perfect condition at their location. destiny. There are many variants of the lashing or mooring. Thus the loads can be fixed or secured by iron bars, but also by means of straps, cables or lashing straps or chains, for heavier loads.
    [0017] In any case, a tensioning and loosening of the lashing or mooring elements is required, during the respective operations of loading and unloading the containers, an objective that this invention concerns.
    [0019] In this field, the utility model CN 204266120U is known, which discloses a cable tensioning system that consists of a front support frame (67), a tool anchor (66), a tool holding plate (65), a limiting frame (63), a pressure spring (64) and a conversion support frame (62).
    [0021] Another example is found in the utility model CN106567331U which refers to an adjustable steel cable anchor, which is composed of a first self-centering locking clamp, a second self-centering locking clamp, a compression spring and a plain bearing.
    [0023] Patent ES2611585B1, discloses a tensioning system with fast drive that comprises a fast drive nut related to a spindle with rotation and axial displacement to carry out the tensioning of a tie rod, said nut being associated with an axial pinion on which it is capable of engaging a second pinion mounted with the ability to move on a support belonging to an actuating device and enabling two positions of said second pinion, engaging and releasing said axial pinion.
    [0025] The present invention is based on a concept similar to that of this last document, although it proposes a different, simpler embodiment, which allows the tensioning and loosening of a tensioning assembly to be carried out with greater ease and safety, by incorporating a wrench. Stilson or a socket wrench that allows the application of considerable torque by a tool, eg pneumatically actuated.

On the other hand, the shaft 40a of the first gear 40 is configured with a polygonal section to couple and be actuated by a tool 18, in particular a pneumatic tool. Furthermore, the aforementioned casing 9 has two opposite faces 34, 35, flat, spaced apart, in such a way that the casing 9 can be arranged housed, being fitted and immobilized between the two arms 31, 32 with the faces 34, 35 attached to them. , and with the socket wrench 50 coupled to the polygonal contoured portion 5b of the quick-acting nut 5.
    [0066] The two arms 31, 32 are parallel and coplanar, and are at a distance that corresponds approximately, with the separation between the faces 34, 35, allowing the casing 9 to be housed between them and being retained, as explained.
    [0068] As shown in Fig. 3a, the housing 9 further houses a third gear 41 with a rotation shaft 41a, this third gear 41 being meshed with the previous first and second gears 40 and 42 such that a multiplier gear set is provided. of the driving torque that is applied to the pinion shaft 40a of the first gear 40.
    [0070] As can be seen in the figure, the aforementioned first, second and third gears 40, 41 and 42 constitute in fact some pinions, the first of them 40 being the drive pinion, the second 41 an intermediate pinion and the third 42 the remaining pinion. attached and coaxial to socket wrench 50.
    [0072] The three pinions 40, 41 and 42 are arranged within respective three recesses 61 that house and guide portions of the rotation axes 40a, 41a and 42a.
    [0073] In the embodiment of the example illustrated in Fig. 3a a part of said recesses is formed in a lid 60 of the box 9.
    [0075] The drive 40 and intermediate pinions 41 have a tubular portion of their axes 40a, 41a housed in bearing sleeves 62, contained in the aforementioned recesses 61 and the third pinion 42 attached to the tube wrench 50 has portions of its axis tubular 42a and section 50a, adjacent to the pipe wrench 50, surrounded by an antifriction bushing 43, which in this embodiment is constituted by a split annular element, comprising two members that coaxially embrace a tubular section 50a immediately to the body of the pipe wrench 50. The figure also shows a second anti-friction bushing 44 with tubular shaft 42a.
    [0077] The nut 5 can take two different configurations as shown in Figures 3b and 3c.
    [0079] Thus, in relation to Fig. 3b, a first tubular portion with threaded interior 5a and a second portion 5b with a polygonal contour can be seen, which extends the first portion 5a, axially and said second portion 5b with a polygonal contour is of greater diametrical span than the first portion 5a is threaded inside and has a hexagonal outer contour.
    [0081] In Fig. 3c another embodiment is shown in which the first and second portions 5a, 5b, are coaxial and share the same longitudinal section.
