Description

A safe lifting mechanism for high-altitude power maintenance

Technical Field

The utility model belongs to the technical field of electric power engineering, in particular to a safe lifting mechanism for high-altitude electric power maintenance.

Background technique

High-altitude power maintenance is high-altitude power work. High-altitude power work refers to the maintenance and construction work carried out at high altitudes of power facilities. High-altitude power work is mostly the inspection and maintenance of facilities such as lines and substations. During the inspection and maintenance process, inspection tools and materials are needed, so a lifting mechanism is needed to transport the inspection tools and materials.

Among them, after searching, it was found that there is an application number CN202120791145.3, which discloses a lifting tool for overhead line maintenance of distribution network, including a support plate, a connecting column fixedly installed at the rear end of the support plate, and a sling fixedly installed on the connecting column. There is no motor on the lifting tool, which reduces the labor intensity of the staff. There is no need to carry heavy motors and power supplies on the electric tower. The objects are lifted to a high altitude by hand crank, and the chain is used to drive the gear plate and the winding wheel to rotate to drop the objects. Two sets of gear plates are set. By engaging the chain with gears of different sizes, when lifting low-weight objects, the objects can be lifted more quickly. When lifting high-weight objects, a small gear is used to drive the large gear to rotate, which can save more effort and has the advantage of stably lifting the objects.

However, after research, it was found that during the use of the device, the staff are required to carry the entire device to the power tower, which increases the labor intensity of the staff. In addition, when lifting objects, there is no structure to protect the objects, which makes the objects easy to fall and is not safe to use. Therefore, a new device is provided to solve this problem.

The purpose of the utility model is to provide a safe lifting mechanism for high-altitude power maintenance in order to solve the above-mentioned problems of increased labor intensity of workers and insufficient safety in use.

The technical solution adopted by the utility model is as follows: a safe lifting mechanism for high-altitude electric power maintenance, comprising a transmission tower, the transmission tower has a base outside, and a lifting mechanism for convenient transportation of tools is arranged above the base.

Wherein, the lifting mechanism includes a manual winch, a crank, a connecting rod, a loading tank, a connecting ring and a connecting groove; a manual winch is fixedly installed on one side above the base; the manual winch is equipped with a crank; the lifting material of the manual winch is nylon; the starting end of the nylon rope of the manual winch is connected to a connecting rod, and the outer wall of the connecting rod is provided with a thread; the other side above the base is movably connected with the loading tank through a groove; the center above the loading tank is connected with a connecting ring through a connecting rope; the connecting ring is fixedly installed above A connecting groove, and the inner wall of the connecting groove is provided with an internal thread that matches the thread of the outer wall of the connecting rod. The loading groove is arranged in a cylindrical shape, and a cover plate is threadedly connected to the opening above the loading groove. A support frame is movably connected to the middle part above the base, and a horizontal plate is fixedly installed above the support frame. Pulleys A and pulley C are rotatably connected to both sides of the support frame, and pulley B is rotatably connected below the horizontal plate, and pulley B is located between pulley A and pulley C, and a through groove is provided on the surface of the support frame near pulley A, and a guide wheel is rotatably connected to one side of the support frame.

1. In the utility model, the device is divided into three parts: a base, a support frame and a loading trough. The staff only needs to carry the support frame to the top of the transmission tower, and there is no need to carry the entire device to the top of the transmission tower, which reduces the labor intensity of the staff.

2. In the utility model, during the lifting process, the ground staff rotates the crank in the opposite direction to reel in the nylon rope, so that the starting end of the nylon rope reel moves up slowly, driving the cargo trough to move up at the same time, and the pulleys A, B, C and the guide wheels rotate with the movement of the nylon rope, reducing the friction during the movement of the nylon rope, making the nylon rope move more smoothly, until the cargo trough moves to the top of the transmission tower, the tower top staff removes the tools or materials in the cargo trough, and can transport tools and materials back and forth many times, which is convenient to use.

3. In the utility model, the maintenance tools or materials are placed in the loading tank, and the cover plate is screwed on the opening of the loading tank to confine the maintenance tools or materials inside the loading tank. The cylindrical loading tank has a more stable load-bearing capacity, which prevents the loading tank from turning over and the maintenance tools or materials from falling, making it safer to use.
