Abstract

The invention relates to the field of explosion prevention of elevators, in particular to an explosion-proof elevator. The explosion-proof elevator comprises a car in a hoistway, a car beam for fixing the car, a guide rail for guiding the car, and a guide device; the guide device is arranged on one side, towards the guide beam, of the car, and includes a guide shoe and a safety clamp; the guide shoe includes a guide shoe base, a guide block and an adjusting bolt; the guide block is arranged in the guide shoe base, and a gap with the guide rail is adjusted through the adjusting bolt; the guide block includes a moving block arranged in the guide shoe base, a rotating shaft arranged in the moving block, and a guide belt; an adjusting spring is arranged between the inner wall of the guide shoe base and the moving block, and coats the adjusting bolt; a limiting block for limiting the moving block is arranged on the inner side of the guide shoe base; and a sealing block is arranged between the moving block and the guide belt, so that the guide belt is divided into two parts exposed out of the moving block and sealed in the moving block.

Description

technical field [0001] The invention relates to the field of explosion-proof elevators, in particular to an explosion-proof elevator. Background technique [0002] The main dangerous ignition sources during the operation of the elevator can be divided into four categories: 1. Electrical equipment, including electrical component on-off, load, fault high temperature, sparks; 2. Mechanical collision friction, including mechanical friction high temperature, mechanical collision Sparks; 3. Electrostatic discharge, including solid static electricity of elevator components and elevator passengers; 4. Dangerous energy, including high temperature or sparks generated by improper operations, and high temperature heat sources in the external environment. [0003] In order to ensure the stability of the elevator lifting process, guide rails and guide shoes are usually arranged on both sides of the elevator car beam to guide the elevator to move up and down. In addition, in order to impr...
