Elevator

Abstract

The invention relates to an elevator which comprises a main box body, a wheel disc assembly, a guide cable assembly and a brake assembly, wherein a transmission case is arranged below the back of themain box body; the wheel disc assembly comprises a frontage wheel disc and a back gear; a cable groove is formed in the outer circumference of the frontage wheel disc; the guide cable assembly comprises a wheel frame; a top guide wheel is mounted at the top of the wheel frame; a bottom guide wheel is mounted at the bottom of the wheel frame; the guide cable assembly further comprises a middle guide wheel; the brake assembly comprises a stand column; a first support arm is mounted and fixed on the reverse side of the stand column; a second support arm is mounted and fixed on the obverse side ofthe stand column; a jacking block is mounted at the front end of the first support arm; a brake motor is arranged on the side part of the first support arm; a jacking wheel is mounted at the front end of the motor shaft of the brake motor; a longitudinal elastic component is mounted below the front end of the second support arm; a triangular wheel seat is hinged to and mounted at the middle of the second support arm; two pressing wheels are mounted on the wheel seat; a top cable hole is formed in the top wall of the main box body; a bottom cable hole is formed in the bottom wall; and the elevator further comprises a cable guiding block. The elevator is compact in structure, high in elevating capacity, fast in breaking action and reliable.

Description

technical field [0001] The invention belongs to the technical field of lifting car equipment, and in particular relates to a hoist. Background technique [0002] In the field of wind power, elevator facilities are usually used. Tower elevators are elevators used for wind power towers. The wind power towers play a supporting role and also have 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. The tower lift is similar to an elevator. It uses a hoist and a steel cable to drive the car t...

AI Technical Summary

Problems solved by technology

[0003] Existing hoists generally take up a lot of space and have insufficient lifting capacity

On the other hand, the hoist usually has the function of braking, and actively brakes in case of emergency. The existing lift car hoist has slow braking response and unreliable braking effect.
