Description

Technical Field

[0001] The utility model relates to the field of ratchet wire tighteners, in particular to a ratchet wire tightener fixing device. Background Art

[0002] For a long time, the wire tensioner has been directly hooked on the wire rope loop of the crossarm, but the opening of the wire rope loop is relatively large and it is easy to slide left and right along the crossarm. If it slides to the edge of the crossarm and slips off, on the long-distance and multi-angle distribution network line, the side close to the crossarm is not firmly fixed, which is easy to cause safety risks. In the process of tightening and releasing the wires, there may even be uneven force on the pole, resulting in personal injury accidents such as pole collapse. Even if the pole climbers are always careful not to slip left and right during the process of tightening and releasing the wires, it is still easy to sway left and right because the wire rope loop will sway slightly as the operators tighten and release the wires, requiring the operators to tighten and release the wires while paying attention to the wire rope loop, which is inconvenient and reduces work efficiency. Utility Model Content

[0003] The utility model aims to provide a ratchet tensioner fixing device, which is simple and portable, can prevent the wire ring rope from slipping out, and improves safety.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is a ratchet tensioner fixing device, comprising an "inverted L-shaped" upper clamping plate adapted to the cross arm and an "inverted L-shaped" lower clamping plate adapted to the cross arm and fixed to the upper clamping plate by bolts;

[0005] The upper clamping plate includes bolt hole grooves protruding outwards and matching with bolts, which are respectively opened near the edges of both ends of the clamping plate. A U-shaped connecting rod for active connection with the locking hook of the ratchet tensioner is fixedly arranged above any one end of the clamping body of the upper clamping plate.

[0006] The lower clamping plate comprises bolt holes which are respectively opened at two ends of the clamping plate near the edges and correspond to the positions of the bolt hole grooves.

[0007] Furthermore, the upper clamping plate and the lower clamping plate are steel plates.

[0008] Furthermore, two parallel upper clamping plate bolt grooves that cooperate with the bolts are fixedly provided at the clamping plate edge of the upper clamping plate below the U-shaped connecting rod, and a lower clamping plate bolt groove that protrudes upward and is located between the two upper clamping plate bolt grooves and cooperates with the bolts is fixedly provided at the clamping plate edge at one end of the lower clamping plate.

[0009] Furthermore, a triangular support plate for reinforcing support is fixedly provided at the angle of the lower clamping plate.

[0010] Furthermore, the fixing method is welding or integral molding.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model is composed of two clamping plates adapted to the cross arm, and has a simple structure and is convenient to carry; the two clamping plates are tightly fitted and fixed to the cross arm by bolts, thus avoiding the problem that the wire rope loop used in the prior art is easy to slip out, and preventing the risk of pole toppling and wire breakage caused by this; at the same time, since the device is fixed on the cross arm, there is no need for the operator to actively adjust it, and the wire rope loop will not easily swing left and right like the wire rope loop, causing the locking hook of the tensioner close to the cross arm to fail, thereby reducing the service life of the tensioner and increasing the risk of the wire rope loop falling off the hook, thereby greatly improving safety and work efficiency.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1 and 2 The ratchet tensioner fixing device shown in the figure comprises an "inverted L-shaped" upper clamping plate 1 adapted to the cross arm and an "inverted L-shaped" lower clamping plate 2 adapted to the cross arm and fixed to the upper clamping plate 1 by bolts. The shape of the clamping plate is adapted to the cross arm and can fit more closely with the cross arm. It should be noted that both the upper clamping plate 1 and the lower clamping plate 2 are made of steel plate or carbon fiber material to further ensure the stability of the fixing device structure.

[0023] like Figure 3 The upper clamping plate 1 shown in the figure includes bolt hole grooves 11 protruding outwards and cooperating with bolts at the edges of both ends of the clamping plate, respectively, for locking the bolts; a U-shaped connecting rod 12 for active connection with the ratchet tensioner lock hook is fixedly arranged above either end of the clamping body of the upper clamping plate 1; Figure 4 The lower clamping plate 2 shown includes bolt holes 21 respectively opened at both ends of the clamping plate near the edge and corresponding to the position of the bolt hole slot 11, for the bolts to pass through and thus connected to the upper clamping plate 1; it should be noted that the upper clamping plate 1 is fixedly set by welding or integral molding to improve safety;

[0024] Further as Figure 5 and 6 As shown, two parallel upper clamping plate bolt grooves 13 that match the bolts are fixedly arranged at the clamping plate edge of the upper clamping plate 1 below the U-shaped connecting rod 12, and a lower clamping plate screw groove 22 that protrudes upward and is located between the two upper clamping plate bolt grooves 13 and matches the bolts is fixedly arranged at the clamping plate edge at one end of the lower clamping plate 2, so that the connection between the upper and lower clamping plates is more stable and the safety is improved; see Figure 7 A triangular support plate 23 for reinforcing support is fixedly provided at the angle of the lower splint 2 to improve the stability of the house. It should be noted that the fixing method of the lower splint 2 is welding or one-piece molding, which also improves safety.

[0025] When the device is in use, the operator first adjusts one side of the U-shaped connecting rod 12 of the upper clamping plate 1 and one side of the lower clamping plate bolt groove 22 of the lower clamping plate 2 to the upper side, and then respectively places them on the upper and lower sides of the cross arm, and takes two bolts through the corresponding bolt hole grooves 11 and bolt holes 21 to fix the upper and lower clamping plates in connection, and then takes another bolt through the upper clamping plate bolt groove 13 and the lower clamping plate bolt groove 22 to further fix them, and finally puts the ratchet tensioner lock hook into the U-shaped connecting rod 12 to start production operations.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
