DETAILED DESCRIPTION

[0027] The present invention is further described in detail below through specific examples. The following examples are only illustrative and not restrictive, and the protection scope of the present invention cannot be limited thereto.

[0028] A foldable cable bracket for power transmission, the innovation of which lies in: comprising a foldable frame body for easy storage and transportation, a cable locking mechanism for limiting the position of the cable and a contact bracket 9 for supporting the contact, a cable locking mechanism is arranged on the support shaft of the foldable frame body at intervals through a positioning ring 7, and a contact bracket is rotatably mounted on the support shafts at both ends of the cable locking mechanism.

[0029] The folding frame includes a front frame 4, a rear frame 2 and a support shaft. Both the front frame and the rear frame are U-shaped structures. The horizontal part of the U-shaped structure is supported on the ground, and the two vertical parts of the U-shaped structure are connected to the support shaft. The front frame is rotatably mounted on the two end shafts of the support shaft through a rotating sleeve 3, and the rear frame is mounted on the two ends of the support shaft through an elbow 1. The rotating sleeve is a three-way structure, the horizontal part of the three-way structure is sleeved on the support shaft, and the front frame is mounted on the vertical part of the three-way structure.

[0030] In this embodiment, there are two groups of cable locking mechanisms, which are separated by a positioning ring. Each group of the cable locking mechanisms includes a cable roller 6, a wire pressing sleeve 8 and a wire pressing clamp 5. Two cable rollers are rotatably mounted on the support shaft. A wire pressing sleeve fixed on the support shaft is provided between the two cable rollers. A wire pressing clamp is installed on the wire pressing sleeve by a fastening screw. The pressure adjustment between the wire pressing clamp and the cable on the cable roller is achieved by the fastening screw 12 on the wire pressing clamp. When the cable passes through the cable roller, the wire pressing clamp is lifted. After passing through, the wire pressing clamp is pressed against the cable by the fastening screw to achieve the locking and limiting of the cable.

[0031] The contact bracket includes a support beam 13 and a support beam 14. The support beams are rotatably mounted on the support shafts at both ends of the cable locking mechanism. A support beam is installed at the front end between the two support beams. Support grooves 15 are arranged at intervals on the support beam. The positions of the support grooves correspond to the positions of the cable rollers. The support beam is fixed on the support shaft by fixing screws 11. When the cable needs to be connected to the power generation vehicle for emergency repair, the contact bracket is lifted and fixed by fixing screws. The contact bracket can support the contact to prevent the contact from being collided and entering the power generation vehicle to cause a safety accident.

[0032] It also includes a bracket angle adjustment mechanism 10, the bracket angle adjustment structure includes an angle adjustment joint 21, an angle adjustment joint locking handle 23 and a three-hole positioning ring 19, the angle adjustment joint includes an angle adjustment ring body, and mounting through holes are respectively provided at both ends of the angle adjustment ring body, a guide rod 24 extending from one side is fixedly installed in the mounting through hole at one end, a pin shaft 20 with an external sleeve spring 22 is limitedly installed in the mounting through hole at the other end, and an angle adjustment joint locking handle is provided at the end of the pin shaft;

[0033] The three-hole positioning ring includes a positioning ring body, an adjustment long hole 17, a large-angle positioning circular hole 16 and a small-angle positioning circular hole 18. The large-angle positioning circular hole and the small-angle positioning circular hole are arranged at intervals at one end of the positioning ring body, and the adjustment long hole is arranged at the other end of the positioning ring;

[0034] An angle adjustment joint is fixedly installed on the inner outer ring of the rotating sleeve, and a three-hole positioning ring is fixedly installed on the inner supporting shaft of the angle adjustment joint. The guide rod of the angle adjustment joint slides in the adjustment long hole of the three-hole positioning ring. The angle adjustment joint realizes the angle adjustment of the folding bracket by inserting its pin shaft into the large-angle positioning circular hole or the small-angle positioning circular hole of the three-hole positioning ring.

[0035] When the height of the present invention needs to be adjusted, the angle adjustment joint locking handle is pulled out and then rotated to another hole position of the three-hole positioning ring to meet the requirements of different heights and folding of the bracket.

[0036] The structural design of the present invention is scientific and reasonable, and has strong processability. It can realize the support of the cable when the cable folding bracket is opened during power transmission. After the repair is completed, it is convenient to fold and occupy a small space, and is easy to load and carry. In particular, the design of the cable roller on the folding bracket allows the cable roller to rotate during the cable dragging process, which saves effort and time and protects the cable from wear.

[0037] When the cable is in working state, the cable locking mechanism of the cable folding bracket locks the cable to prevent the cable from moving. When the cable is connected to the emergency generator, to prevent the contact from falling and being damaged, a contact bracket is set on the cable folding bracket to lift the contact and share it with the cable folding bracket. After the emergency repair is completed, the contact bracket is put away and the cable bracket is folded, which is simple and convenient.
