Description

A transmission line insulator remover Technical Field

[0001] The present invention relates to the technical field of power operation auxiliary devices, and in particular to a transmission line insulator remover. Background Art

[0002] High-voltage transmission lines often experience single-piece insulator explosions or zero-value insulators. To maintain the normal insulation level of the line and ensure safe and stable operation, the self-exploded insulators and the detected zero-value insulators need to be replaced. When replacing the insulator, the R pin on the insulator must be pulled out to remove the insulator connection.

[0003] When using the existing insulator pin remover, the pin hook is inserted into the R pin, and then the pin hook is hit hard with the handle of the pin remover. Repeating this two or three times can pull out the R pin. The disadvantage is that it is very violent when used. Once the hook is disengaged during the hard hit, it may cause certain personal safety risks. In addition, once the R pin is stuck when the insulators are squeezed against each other, it will be impossible to remove the R pin even after hitting the pin hook multiple times. The efficiency is very low and the physical exertion of the operator is great.

[0004] Summary of the Invention

[0005] The present invention provides a transmission line insulator pin remover, which solves the problems of existing insulator pin removers being difficult to operate, prone to injury to operators, requiring great physical effort, and having low operating efficiency.

[0006] The technical solution of the present invention is: a transmission line insulator pin remover, including a base, a lifting rod, and a gear crank. The base is hollow and has a slide rail inside. The lifting rod is installed in the slide rail. A gear crank seat is provided on one side of the top of the base. The gear crank seat is rotatably connected to the gear crank. A rack is provided on one side of the top of the lifting rod. The rack is engaged with the gear on one side of the gear crank. The other side of the gear crank is connected to the crank. A gear crank cover is fixed to the other side of the gear crank seat by bolts. A pin hook is provided at the bottom of the lifting rod. The pin hook is used to hook the insulator R pin. A groove is provided on one side of the base. The pin hook moves up and down in the groove. A U-shaped socket is provided at the bottom of the base.

[0007] Preferably, there is a spring between the top of the base and the lifting rod.

[0008] Preferably, the base is made of aluminum alloy.

[0009] Preferably, the gear crank and lifting rod are made of steel.

[0010] Preferably, the inner wall of the U-shaped seat is provided with a rubber pad.

[0011] Preferably, the crank on one side of the gear crank has an engineering plastic handle.

[0012] Preferably, there are T-shaped slide rails on both sides of the lifting rod, and corresponding slide grooves are arranged in the base.

[0013] The principle of the present invention: The present invention adopts the lever principle to remove the insulator R pin, and changes the torque transmission direction through the base and the lifting rod, so that the operator can easily remove the insulator R pin, effectively improving the working efficiency; the above technical effects are achieved through the following technical solutions: the gear crank serves as a lever, the fulcrum is the rotating shaft between the gear crank and the gear crank seat, and the force point is the gear teeth when the gear crank gear is meshed with the rack. The operator applies downward pressure on the crank on one side of the gear crank, and transmits the torque to the gear teeth when meshing through the fulcrum. Under the action of continuous downward pressure, the lifting rod moves up and down in the base to complete the torque transmission. The insulator R pin mounted on the pin hook at the bottom of the lifting rod will be slowly pulled out to complete the R pin removal operation. There is a U-shaped socket at the end of the base that can fit with the insulator metal cap to avoid slipping of the base and the insulator metal cap during operation, affecting the working efficiency, avoiding excessive force, and injuring the operator. Compared with the existing pin remover, the working efficiency is higher, more labor-saving, safer and more reliable.

[0014] The beneficial effects of the present invention are as follows: a transmission line insulator remover has a scientific and reasonable structural design, excellent ergonomics, low manufacturing cost, is easy to use, saves time and effort, is safe and efficient, effectively improves operating efficiency, reduces the physical exertion of operators, and has high promotion value.

[0019] The specific embodiment of the present invention is as follows: as shown in Figures 1, 2 and 3, a transmission line insulator pin remover includes a base 101, a lifting rod 102 and a gear crank 104. The base 101 is hollow and has a slide rail inside. The lifting rod 102 is installed in the slide rail. A gear crank seat 103 is provided on one side of the top of the base 101. The gear crank 104 is rotatably connected to the gear crank seat 103. A rack 106 is provided on one side of the top of the lifting rod 102. The rack 106 is engaged with the gear on one side of the gear crank 104. The other side of the gear crank 104 is connected to the crank. A gear crank cover 105 is fixed to the other side of the gear crank seat 103 by bolts. A pin hook 107 is provided at the bottom of the lifting rod 102. The pin hook 107 is used to hook the insulator R pin. A groove is provided on one side of the base 101. The pin hook 107 moves up and down in the groove. A U-shaped clamping seat 108 is provided at the bottom of the base 101. The separate design of the gear crank cover 105 and the gear crank seat 103 helps to reduce manufacturing costs and facilitates operators to maintain the equipment.

[0020] Specifically, a spring 109 is provided between the top of the base 101 and the lifting rod 102. The spring 109 is used to reset the lifting rod 102.

[0021] Specifically, the base 101 is made of aluminum alloy. The base 101 can be made of aluminum alloy by CNC, which can reduce weight while obtaining appropriate mechanical strength.

[0022] Specifically, the gear crank 104 and the lifting rod 102 are made of steel. The gear crank 104 and the lifting rod 102 made of steel have high mechanical strength and are not easily deformed during use, thereby improving the reliability of the device.

[0023] Specifically, a rubber pad is provided on the inner wall of the U-shaped holder 108. The friction between the rubber pad and the insulator metal cap is relatively large, so the U-shaped holder 108 and the insulator metal cap are not easy to slip during use, thereby ensuring the safety of the operator.

[0024] Specifically, the crank on one side of the gear crank 104 has an engineering plastic handle. The engineering plastic handle provides a comfortable grip, improves ergonomics, and helps improve work efficiency.

[0025] Specifically, the lifting rod 102 has T-shaped rails on both sides, and corresponding slide grooves are set in the base 101. The T-shaped rails improve the mechanical strength of the lifting rod 102, making it less likely to bend during use, while also increasing the contact area with the slide grooves of the base 101, making the lifting rod 102 run more smoothly.

Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and descriptions are merely illustrative of the principles of the present invention.
