Integrated security device of elevator

Abstract

The invention relates to an elevator-integrated safety device, aiming at filling the gap of the prior art and combining the functions of an over-speed governor, a guide shoe, a safety gear and a safety guidance mechanism into an integrated mechanism which is arranged at the bottom of an elevator cage to realize the guidance and over-speed protection functions during the running process of the elevator. The safety device comprises a guiding device, a safety gear device including the safety gear and a lifting rod which is connected between a ratchet wheel and the safety gear, when being lifted to a certain stroke, the lifting rod can lead the safety gear to clamp a guide rail and stop the elevator, and the lifting rod appears as a bended rod or a rack, a shell and a base board. As an ideal elevator guidance and over-speed protection device, the elevator-integrated safety device of the invention has scientific and reasonable design, compact structure, largely saved well space, convenient site installation and debugging, simple maintenance, low manufacturing cost and safe and reliable use.

Description

technical field [0001] The invention relates to an elevator integrated safety device, which is a device integrating various safety functions such as a speed limiter, a safety gear, a guide shoe, etc., and has the functions of guiding an elevator car and protecting overspeed. Background technique [0002] The elevator car, including the elevator carrying people or goods, runs up and down along the guide rails in the elevator shaft, and a guiding device needs to be installed; according to the requirements of the national standard GB7588 "Safety Code for Elevator Manufacturing and Installation": "The car should be equipped with Safety gear that can act when going down", "Safety gear should be able to clamp the guide rail to stop the car with rated load and keep it in a static state", that is, a safety device should be installed on the car. At present, the safety devices commonly used in the elevator industry include: speed limiter device, safety gear, safety gear lifting device...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned technology generally used in domestic and foreign elevator industry at present has the obvious shortcoming that: the composition of prior art is by the parts of a plurality of scattered arrangements, and it not only needs to leave enough installation space in the hoistway and machine room, makes the limited The steel wire rope and tensioner in the speed governor device make circular motion without colliding with elevator components; and the installation and adjustment of the speed governor, tensioner, and wire rope, the connection and adjustment of the speed governor wire rope and the lifting mechanism, and the lifting mechanism The connection and adjustment of the safety gear, these tasks are complicated, the workload of manufacturing, installation and commissioning is large and complicated, the technology is difficult, and the cost is high

[0004] After searching Chinese patents, no inventions with the same or similar prior art were found
