Elevator with car anti-slip function

Abstract

The invention relates to an elevator with the car anti-slip function. The elevator comprises an elevator shaft frame, an elevator car and a car anti-slip mechanism, wherein the car anti-slip mechanismcomprises an elevator overspeed governor, a safety gear, a driving rope and a dowel bar; the elevator overspeed governor is mounted on the elevator car and can do short-distance free displacement motion relative to the elevator car; the safety gear is also fixed on the elevator car; the driving rope is wound on the overspeed governor rope wheel of the elevator overspeed governor; the upper end ofthe dowel bar is connected and driven by the elevator overspeed governor; and the lower end of the dowel bar acts on the safety gear, so that on one hand, the distance of the elevator overspeed governor and the safety gear is kept within the controllable range to ensure sensitivity and reliability of the action of the safety gear, on the other hand, the space design layout of a machine room is optimized to certain degree to lay a further foundation for completely eliminating the design target of the machine room, moreover, the mounting efficiency of the elevator overspeed governor is improved, and convenience is provided for following maintenance and renewal operation.

Description

technical field [0001] The invention relates to the technical field of elevator manufacture, in particular to an elevator with the function of preventing slipping. Background technique [0002] The elevator is mainly composed of machine room, traction system, guidance system, elevator car, weight balance system, electric drive system, electrical control system and safety protection system. Among them, the safety protection system is mainly composed of elevator speed limiter and safety gear. In the prior art, the safety gear is fixed on the bottom of the elevator car, and the elevator guide rail is passed through it. The elevator speed limiter is installed in the machine room (such as figure 1 shown in ). The speed limiter of the elevator monitors and controls the speed of the elevator car at any time. When the speed exceeds 115% of the rated speed of the elevator, it can send a signal in time, and then generate a mechanical action to cut off the power supply circuit to bra...

AI Technical Summary

Problems solved by technology

In this way, there are the following problems: 1) the existence of the machine room greatly increases the overall length of the elevator, which increases the investment in manufacturing costs; And increased the design size of the machine room; 3) When the elevator speed limiter is far away from the brake, it will affect its own braking sensitivity to a certain extent, causing potential safety hazards; 4) When the elevator speed limiter occurs When a fault occurs, it is not convenient for operators to enter the machine room for maintenance operations
