Description

Technical Field

[0001] The utility model relates to the technical field of electric power engineering, and particularly relates to a multifunctional catenary wrist arm insulator replacement device. Background Art

[0002] The operating environment of high-speed railways is complex, and most of the catenary equipment is exposed to the natural environment. Insulating equipment, including wrist arm rod insulators, is extremely vulnerable to external environmental influences such as rain, snow, fog, ice, lightning, and pollution, resulting in flashovers and breakages, which induce potential safety hazards. When the insulator is damaged, it needs to be replaced in a timely manner. Traditionally, when replacing the inclined wrist arm insulator, it is mainly replaced through a "hand winch". One end of the hand winch is fixed at the top of the pillar, and the other end is fixed at the double sleeve connector. Two people cooperate to tighten the hand winch. After the insulator is removed from the inclined wrist arm opening, the insulator is replaced. The operation steps are cumbersome, resulting in too long replacement operation time and low efficiency. In view of the above problems, the inventor proposes a multifunctional catenary wrist arm insulator replacement device to solve the above problems. Content of the Utility Model

[0003] In order to solve the problem of tight time and low efficiency in replacing the inclined wrist arm insulator; the purpose of the utility model is to provide a multifunctional catenary wrist arm insulator replacement device.

Two symmetrically distributed bolts are inserted through the fixed arc frame away from the rotating hinge, and a first nut is threadedly installed on the bolts.

[0007] Preferably, the clamping and fixing assembly includes side plates which are fixedly installed on one side of the base close to the rotating column. A chute is formed on one side of the base close to the side plates. A slider is slidably arranged on the inner wall of the chute. A clamping plate is fixedly arranged at one end of the slider away from the base.

[0008] Preferably, two symmetrically distributed guide rods are fixedly arranged on the fixed frame. A fixed block is slidably sleeved on the outer wall of the guide rod, and the fixed block is fixedly connected with the lifting frame.

[0029] By adopting the above technical solution, after the fixed arc frame 601 and the rotating arc frame 602 are closed, they are fixedly connected by the bolts 603 and the first nut 604.

[0030] The clamping and fixing assembly 7 includes a side plate 701, which is fixedly installed on the base 1 close to one side of the rotating column 2.

One end of the slider 703 far from the base 1 is fixedly provided with a clamping plate 704.

[0031] By adopting the above technical solution, the clamping plate 704 is slidably installed on the base 1.

Similarly, when the rotating handle 504 is rotated in the reverse direction, the lifting frame 505 moves upward. By moving the lifting frame 505, the distance between the fixed arc-shaped frame 601 and the transmission column 4 is adjusted, so that the rotating column 2, the bidirectional threaded rod 3 and the transmission column 4 are horizontal with the inclined cross arm. Then, close the rotating arc-shaped frame 602 and the fixed arc-shaped frame 601 and fixedly install them on the inclined cross arm through the screw rod 705 and the second nut 706. Finally, manually rotate the crank 301, the crank 301 drives the bidirectional threaded rod 3 to rotate, and the rotation of the bidirectional threaded rod 3 drives the rotating column 2 and the transmission column 4 to move away from each other, so that the inclined cross arm is disengaged from the insulator and the insulator is replaced. After replacement, rotate the crank 301 in the reverse direction to make the inclined cross arm enter the newly replaced insulator. After the insulator replacement is completed, it can be removed according to the above opposite operations.
