Anti-falling speed reducer for building construction elevator

Abstract

The anti-falling speed reduction device for the building construction elevator comprises a guide rail, a guide groove is formed in one side of the guide rail, a guide block is slidably connected into the guide groove, a plurality of mounting grooves are formed in the side wall of the guide groove, a first sliding groove is formed in the side wall of each mounting groove, and two first sliding blocks are slidably connected into each first sliding groove; first springs are fixed between the two first sliding blocks, connecting rods are rotatably connected to the inner sides of the first sliding blocks, a speed reduction block is rotatably connected between the two connecting rods, limiting grooves are formed in the inner walls of the two ends of the mounting groove, limiting blocks are slidably connected in the limiting grooves, permanent magnets are fixed in the speed reduction block, and electromagnets are fixed to the bottoms of the guide blocks; an energy storage mechanism is arranged in the guide block; when an elevator falls, generated airflow drives the first fan blades to rotate, then induction current is generated through the coil sleeve and the annular magnet to supply power to the electromagnet, then the speed reduction block is gradually pulled out, speed reduction is formed on the guide block till the guide block is stopped, and therefore the anti-falling speed reduction effect is achieved.

Description

technical field [0001] The invention relates to the technical field of building construction elevators, in particular to an anti-fall deceleration device for building construction elevators. Background technique [0002] Construction elevators are usually called construction elevators, but construction elevators include a broader definition, and construction platforms also belong to the construction elevator series. A simple construction elevator is composed of a car, a drive mechanism, a standard section, an attached wall, a chassis, a fence, and an electrical system. It is comfortable and safe to ride, and construction elevators are usually used with tower cranes on construction sites. [0003] During the use of the elevator, if there is an unexpected situation, such as a power failure, it will fall, which poses a great safety hazard to the user. Therefore, the elevator is generally equipped with an anti-fall deceleration device, but the anti-fall deceleration device on t...
