Description

Technical Field

[0001] The present invention relates to the technical field of insulator clamping tools, and specifically relates to a composite tension insulator lifting fixture. Background Art

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding member, and can withstand voltage and mechanical stress. There are many types of insulators with various shapes. Although the structures and outer shapes of different types of insulators vary greatly, they are all composed of two major parts: an insulating part and a connecting fitting. An insulator is a special insulating control device that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles. Slowly, many disc-shaped insulators were hung at one end of the high-voltage wire connection tower. It is used to increase the creepage distance and is usually made of glass or ceramic, and is called an insulator.

[0003] For the current composite tension insulator lifting fixture, when workers install the tension insulator, the fixture fixes the tension insulator, and the workers manually lift the fixture and the insulator to perform the transfer work of the insulator. The workers at a high position receive the insulator for installation work. It is difficult for the workers to grasp the angle of the fixture and the insulator, resulting in a long docking time and the insulator is likely to fall during the docking work.

[0018] The present invention provides a composite tension insulator lifting jig. It has the following beneficial effects:

[0019] 1. For this composite tension insulator lifting jig, by setting a positioning mechanism, a gripping mechanism and a clamping mechanism, the insulator is clamped and fixed and lifted. When the worker installs the tension insulator, the jig fixes the tension insulator, and the worker manually lifts the jig and the insulator to perform the transfer work of the insulator. The worker at a high place receives the insulator for installation work. It is difficult for the worker to grasp the angle of the jig and the insulator, resulting in a long docking time, and the insulator is likely to fall during the docking work. Therefore, a positioning mechanism, a gripping mechanism and a clamping mechanism are set to fix the position where the worker holds the hand, ensure that the clamping mechanism and the insulator are in a vertical state, and facilitate the docking work to solve the above problems.

[0020] 2. For this composite tension insulator lifting jig, by setting a positioning mechanism, the position where the worker holds the hand is fixed. Before lifting the insulator, move the device to the lifting location and align the clamping mechanism with the lifting position. Adjust the positioning mechanism, and the position of the device can be fixed by adjusting the position of the suction cup. The fixing and disassembling work is convenient and simple. Moreover, the gripping mechanism and the clamping mechanism are fixed above the positioning mechanism and can maintain a vertical state, so that the insulator can maintain a vertical state, facilitating the docking work.

[0021] 3. For this composite tension insulator lifting jig, by setting a gripping mechanism, with the cooperation of the positioning mechanism, the worker moves the device to the lifting location and holds the arc-shaped plate. The gripping mechanism fixes the worker's hand, and the rubber pressing plate and the arc-shaped plate with friction blocks are used to increase the friction between the worker's hand and the holding position, avoiding the worker's hand slipping when installing or disassembling the positioning mechanism and the gripping mechanism, and preventing the insulator or parts from falling.

[0022] 4. The composite tension insulator lifting fixture clamps and fixes the insulator by setting a clamping mechanism. Most insulator lifting fixtures fix the insulator externally in a circular shape, and the fixed position is not necessarily in the exact middle of the insulator, resulting in the insulator being in an inclined state and affecting the docking operation. Therefore, two second fixing frames, two groups of fourth telescopic rods, and two groups of semi-circular plates are set to fix the insulator in a circular shape at two symmetrical positions, improving stability to solve the above problems.

A first magnetic column 509 is slidably connected to the inside of the annular groove 508. A clamping groove is provided in the annular groove 508. The first magnetic column 509 is snap-connected to the clamping groove.

[0041] The worker holds the arc-shaped plate 502 and manually adjusts the length of the second adjusting rod 503 so that the pressing plate contacts the worker's hand to fix the worker's hand.

[0042] When the insulator needs to be lifted, according to the docking position, manually adjust the position of the first magnetic column 509 in the annular groove 508 so that the first magnetic column 509 is snap-connected to the corresponding clamping groove. Turn on the second telescopic rod 504. The second telescopic rod 504 drives the clamping mechanism 6 to move upward, and then drives the insulator in the clamping mechanism 6 to move upward.

[0043] A second magnetic column 601 is fixedly connected to the bottom of the fixing ring 506. The second magnetic column 601 is slidably connected in the annular groove 508.

[0045] After the semi-circular plate 612 is used for a long time, impurities are easily attached to the inner wall of the semi-circular plate 612. When the semi-circular plate 612 contacts the insulator, it is easy to damage the insulator. Use the circular plate 610 and the brush head to contact the semi-circular plate 612 to clean the semi-circular plate 612.

[0046] There are two fourth telescopic rods 611 and two semi-circular plates 612, and they are symmetrically arranged. The two semi-circular plates 612 are snap-connected.

[0047] Before using the device, turn on the third telescopic rod 606. The third telescopic rod 606 drives the adjusting bent rod 607 and the top plate 608 to move upward, and the top plate 608 moves away from the second fixing bracket 605. Adjust the third telescopic rod 606 to the reciprocating motion mode. The third telescopic rod 606 drives the annular plate 610 to move up and down. The annular plate 610 and the brush head come into contact with the two upper semi-circular plates 612 to clean the two upper semi-circular plates 612. Then manually adjust the length of the fifth adjusting rod 609 and repeat the above actions to clean the two lower semi-circular plates 612.

[0049] Before clamping and fixing the insulator, according to the size of the insulator, manually adjust the length of the fourth adjusting rod 603, and then adjust the distance between the two second fixing brackets 605. Place the insulator between the semi-circular plates 612. Turn on the two fourth telescopic rods 611. The fourth telescopic rods 611 drive the semi-circular plates 612 to move until the two semi-circular plates 612 are snap-connected. The upper and lower groups of semi-circular plates 612 are symmetrically fixed on the outside of the insulator.

[0050] The positioning mechanism 2 includes a support frame 201. The top of the support frame 201 is fixedly connected to a telescopic column 202.

[0051] The outside of the first base 1 is fixedly connected to an adjusting plate 205. The outside of the adjusting plate 205 is fixedly connected to a second base 206. Channels 207 are opened in both the first base 1 and the second base 206. The top of the circular plate 213 is fixedly connected to a first telescopic rod 208. The top of the first telescopic rod 208 is fixedly connected to a support ring 209. A magnetic sheet is arranged inside the support ring 209. The magnetic sheet is in the shape of multiple circular blocks. The support ring 209 is slidably connected to the outside of the clamping rod 204. The top of the first base 1 is fixedly connected to a spring 210. The top of the spring 210 is fixedly connected to a first fixing bracket 211.

There are two springs 210, and they are symmetrically arranged. The top of the first fixing bracket 211 is fixedly connected to a handle.

[0052] After moving the device to the designated position, manually press down the handle. The handle drives the first fixing frame 211 to move downward. At this time, the spring 210 is compressed. The first adjusting rod 212 at the bottom of the first fixing frame 211 drives the suction cup to move downward until the suction cup is suction-fixed on the ground, and the position of the device is fixed at this time.

[0053] According to the height of the worker, the stroke of the first telescopic rod 208 can be adjusted. The first telescopic rod 208 drives the support ring 209 to move upward. The magnetic sheet in the support ring 209 is suction-fixed to the connecting ring 3, thereby fixing the position of the grasping mechanism 5.

[0054] Working principle: Before using the device, turn on the third telescopic rod 606. The third telescopic rod 606 drives the adjusting bent rod 607 and the top plate 608 to move upward, and the top plate 608 moves away from the second fixing frame 605. Adjust the clamping mechanism 6 to fix the position of the insulator, and adjust the height of the grasping mechanism 5 according to the height of the user.

[0055] Before clamping and fixing the insulator, manually adjust the length of the fourth adjusting rod 603 according to the size of the insulator, thereby adjusting the distance between the two second fixing frames 605. Place the insulator between the semi-circular plates 612. Turn on the two fourth telescopic rods 611. The fourth telescopic rods 611 drive the semi-circular plates 612 to move until the two semi-circular plates 612 are snap-connected, and the upper and lower groups of semi-circular plates 612 are symmetrically fixed outside the insulator.

[0056] Subsequently, according to the placement position of the insulator, move the position of the device so that the clamping mechanism 6 is below the placement position. Adjust the positioning mechanism 2 to fix the position of the device. Manually press down the handle. The handle drives the first fixing frame 211 to move downward. At this time, the spring 210 is compressed. The first adjusting rod 212 at the bottom of the first fixing frame 211 drives the suction cup to move downward until the suction cup is suction-fixed on the ground, and the position of the device is fixed at this time.

[0057] Turn on the grasping mechanism 5 and the clamping mechanism 6 to perform the lifting work of the insulator and complete the docking work of the insulator. According to the docking position, manually adjust the position of the first magnetic column 509 in the annular groove 508 so that the first magnetic column 509 is snap-connected to the corresponding card slot. The first magnetic column 509 drives the second magnetic column 601 to move, thereby adjusting the position of the clamping mechanism 6. Turn on the second telescopic rod 504 to the designated stroke. The second telescopic rod 504 drives the clamping mechanism 6 to move upward, thereby driving the insulator in the clamping mechanism 6 to move upward. Send the insulator to the staff working at height. When the staff grabs the top or bottom of the insulator, adjust the fourth telescopic rod 611 to gradually move the semi-circular plate 612 away from the insulator to complete the docking work.

[0058] Before or after using the device, adjust the third telescopic rod 606 to the reciprocating motion mode. The third telescopic rod 606 drives the annular plate 610 to move up and down. The annular plate 610 and the brush head come into contact with the two upper semi-annular plates 612 to clean the two upper semi-annular plates 612. Subsequently, manually adjust the length of the fifth adjusting rod 609 and repeat the above actions to clean the two lower semi-annular plates 612.
