Power grid construction safety lifting frame

Abstract

The invention discloses a power grid construction safety lifting frame which comprises a lifting frame body, a fixing assembly, an extending assembly and the ground. A preformed groove is formed in the ground, a pre-inserting pipe is fixedly connected to the preformed groove, the pre-inserting pipe is fixedly connected with the lifting frame body, the lifting frame body comprises an outer frame, alifting groove and a guardrail, the lifting frame body is provided with an outer frame, the outer frame is provided with a lifting groove, the lifting frame body is provided with the guardrail, the guardrail is fixedly connected with a sliding frame, and the fixing assembly comprises a first thread, an inserting rod, a screw rod, a sleeve, a sliding rod, a motor, a connecting rod and a rotating wheel. According to the power grid construction safety lifting frame, the safety performance of a device is improved, meanwhile, the stability of the device during lifting can be improved through sliding of a limiting sleeve on a limiting rod arranged on the outer frame, the situation that the device is not prone to standing due to inclination during lifting is avoided, the lifting construction process is facilitated, the practicability of the device is improved through an extension plate, and the extensible function of the device is achieved.

Description

technical field [0001] The invention relates to the technical field of lifts, in particular to a safety lift for power grid construction. Background technique [0002] The power grid is a general term for facilities and equipment that connect power generation and power consumption in the power system. The power grid belongs to the intermediate link of power transmission and distribution. It is mainly composed of power transmission lines, substations, power distribution Generally, the unified whole of connected power generation and power consumption composed of power transmission, power transformation, power distribution equipment and corresponding auxiliary systems is called a power network. Referred to as the power grid, the height of the power grid is very high, and at the same time it has a certain high voltage. Therefore, in the process of construction or maintenance of the power grid, it is not only necessary to reach a very high height to construct or maintain it, but ...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing lifting frame only has a certain lifting function. As the plate frame carrying the maintenance personnel rises, a slight instability will cause the entire lifting frame to shake, which will be dangerous. At the same time, the driving mechanism used for lifting is often It needs to carry a lot of additional fixing frames and pulleys to raise the plate frame, which is very inconvenient and does not have the function of safe lifting;

[0004] 2. Due to the large diameter of the power grid, when it is raised to the height required for construction, if there is a certain deviation, there will be a certain distance from the construction area, and it is very inconvenient to adjust the distance after the rise. It will fall down and does not have the function of extending the shelf
