Description

Transmission line lifting aerial work platform

technical field

The invention relates to a power transmission line lifting aerial work platform.

Background technique

To ensure safety, power transmission lines are erected at high altitudes, but once there is a problem with the line, maintenance becomes more difficult.

Although there are aerial work platforms now, the existing work platforms are prone to instability of the work platform, especially the situation that is particularly prone to swinging, and accidents are prone to occur.

Contents of the invention

The purpose of the invention is to overcome the deficiencies of the prior art and provide a power transmission line lifting aerial work platform, which has the advantage of being stable and firm compared with the prior art.

In order to solve the problems of the technologies described above, the technical solution provided by the present invention is:

A power transmission line lifting aerial work platform, including a base, the base is provided with at least four lifting support feet, and a platform, the lower end of the platform is hinged with two telescopic rods, and the lower end of each telescopic rod is hinged There is a sliding seat, and the internal thread is provided on the sliding seat; the two telescopic rods are located in the same plane, and the telescopic rods are symmetrical about the central axis of the platform base, and the two telescopic rods are gradually inclined to each other from bottom to top; The direction of rotation of the thread is opposite; a lead screw is provided in cooperation with the two slide seats, and the lead screw is provided with two parts of threads, and the two parts of threads are reversed, respectively matching with the two internal threads of the slide seat; the two sides of the slide seat are provided with There are two support rods up and down, each end of the two support rods is provided with a bearing, and an adjustment screw is provided. The adjustment screw is located between the two support rods and connected with the internal and external threads of the support rods. On the contrary, it is used to adjust the height of the support rod; the base is provided with a groove, the sliding seat is fixed in the groove, and the outer edge of the bearing is close to the inner wall of the groove.

Described lifting supporting foot is provided with eight.

Working principle of the present invention and beneficial effect are shown in:

The present invention mainly includes a base and a platform; the two are connected by a telescopic rod, and the telescopic rod stretches to realize the up and down movement of the platform. Realize the distance between the two telescopic rods, so as to adjust their stability. The distance between the two is small, and the stability is slightly poor. It is used in the situation that is not particularly high. The distance between the two is large and the stability is good, and it is used in the situation of particularly high. The lead screw is adjusted by the motor, and the adjustment speed is fast.

There is a bearing on the sliding seat, and the bearing is in contact with the groove on the base. Compared with the sliding friction, the distance between the two can be cleared without shaking, and the adjustment is smoother at the same time.

The provided adjusting screw can be rotated to adjust the distance between the two support rods, so as to ensure that the bearing is close to the inner wall of the groove.
