Problems solved by technology

Due to the heavy weight of the wires, especially the 500kV and 1000kV wires, this work is usually completed by two to three people, especially because the wires are too heavy, the bolts are stressed during the removal process, and it is difficult to remove; and in the process of restoring the clamps on both sides, The process of aligning the bolt holes on both sides is extremely difficult. It needs to be aligned repeatedly with tools such as pointed wrenches, which is time-consuming and laborious, and brings inconvenience to maintenance.

Embodiment 1

[0020] Embodiment 1: as Figure 1~7 As shown, in this embodiment, a labor-saving device for disassembling and assembling the main transformer clamp is provided, which includes a pair of steel plates, which include a first steel plate 1 fixed on the main clamp 5 and a first steel plate 1 fixed on the side clamp 6 The second steel plate 2 of the first steel plate is provided with a hand-operated take-up wheel 3 in the middle of the first steel plate, and the hand-operated take-up wheel is provided with steel plates extending to both sides of the second steel plate and fixedly connected to both sides of the second steel plate. Line 4.

[0021] In this embodiment, the first steel plate 1 has several evenly distributed first through holes 110, and the main clamp 5 has several evenly distributed first threaded holes 510 corresponding to the first through holes, and the bolts are sequentially The main clamp is fixedly connected with the first steel plate through the first through ho...

Embodiment 2

[0029] Embodiment 2: On the basis of Embodiment 1, in order to make the device safer to use, a retractor can also be provided inside the hand-cranked reel, and one end of the steel rope can be connected to the output end of the retractor. , is the prior art, referring to a retractor with an emergency locking function, which is mainly used in automobile safety belts.

[0030] The retractor used in this device can give full play to the emergency locking function of the retractor, which greatly improves the safety performance of the device. Such a setting can prevent the winding pressure of the main line clamp and the side line clamp from being too large, causing the hand-cranked line to recycle. The speed of the bullet is too fast, which may cause injury; when paying off the line, the retractor can limit the speed of the line, and when the pressure of the line is too high and the speed cannot be controlled, the hand-cranked take-up wheel will be blocked.

Abstract

The invention provides a labor-saving device for dismounting and assembling the main transformer clamp, which includes a pair of steel plates, and the pair of steel plates include a first steel plate fixed on the main clamp and a second steel plate fixed on the side clamp, the first The middle part of the steel plate is provided with a hand-operated take-up wheel, and the hand-operated take-up wheel is provided with steel wires respectively extending to both sides of the second steel plate and fixedly connected with both sides of the second steel plate. The invention has ingenious design, reasonable structure, saves time and labor, reduces the investment of maintenance personnel, improves maintenance efficiency, and has broad application prospects.

Description

technical field [0001] The invention relates to a labor-saving device for disassembling and assembling a main transformer clip and a using method thereof. Background technique [0002] During the routine maintenance of the main transformer, since the wires on the three sides need to be untied during the high-voltage test of the main transformer, it is necessary to remove the connection part between the wire and the main transformer, that is, the wire clamp part, which includes Main clamp and side clamp connected together in initial state. Due to the heavy weight of the wires, especially the 500kV and 1000kV wires, usually this work is completed by two to three people, especially because the wires are too heavy, the bolts are stressed during the removal process, and it is difficult to remove; and in the process of restoring the clamps on both sides, The process of aligning the bolt holes on both sides is extremely difficult, requiring repeated alignment with sharp wrenches a...
