Tower lift

Abstract

The invention relates to a tower lift, comprising a lifting box body. An upper limiting device is mounted at the top of the lifting box body, a lower limiting device is mounted at the bottom of the lifting box body, a safety speed limiter is also mounted in the lifting box body, and the upper limiting device includes an upper X-shaped support and a lifting top plate; the upper X-shaped support isformed by hinging two rectangular frames in the middle; a support plate is arranged at the bottom of the lifting top plate; the middle of the support plate is positioned in a gap of an upper fixing plate; a return spring is arranged between the lower end of the support plate and the upper fixing plate; an upper proximity switch for detecting the position of the lifting top plate is mounted on thesupport plate; the lower limiting device includes a baseplate mounted at the bottom of the lifting box body; a lower X-shaped support and a lifting bottom plate are arranged below the baseplate; a plurality of guide posts are arranged at the bottom of the baseplate; the lifting bottom plate is provided with a plurality of guide holes correspondingly; a lower proximity switch for detecting the position of the lifting bottom plate is mounted on the baseplate. The tower lift is compact in structure, high in safety and convenient to maintain.

Description

technical field [0001] The invention belongs to the technical field of wind power facilities, and in particular relates to a tower lift. Background technique [0002] The tower lift is a lift used for the wind power tower. The wind power tower plays a supporting role and also has the function of absorbing the vibration of the unit during operation. During the installation and later maintenance process, relevant personnel need to climb from the inside of the tower along the wall of the tower to the wind turbine at the top, and then carry out routine maintenance operations. Usually, the height of the wind power tower is relatively high. The traditional way of climbing with bare hands is not only time-consuming and laborious, but also prone to dangerous situations. The barrel lift solves many of the above problems well. [0003] Tower lifts are similar to elevators. They use driving machines and steel cables to drive the car to move up and down. It is equipped with a guiding ...

AI Technical Summary

Problems solved by technology

[0004] The existing tower lifts are still difficult to meet the increasingly stringent requirements in terms of safety. With the increasing scale of global wind power, tower lifts are increasingly playing a more important auxiliary role. People are concerned about their safety and maintenance convenience. Performance makes increasingly stringent demands
