Abstract

The invention discloses an auxiliary triggering device of pit-free home elevator safety tongs. The auxiliary triggering device comprises a triggering assembly, a locking assembly and a connecting rodassembly, wherein the triggering assembly comprises a tensioning wheel and an elastic reset piece, a cable is pressed on the tensioning wheel to enable the elastic reset piece to be compressed to be in an energy storage state, and then the locking assembly is located at a non-braking position; and the cable is separated from the tensioning wheel so that the elastic reset piece can release the stored elastic potential energy, then the locking assembly can be switched from the non-braking position to the braking position, the locking assembly can clamp a guide rail, and the situation that a carsuddenly falls down due to breakage of the cable is prevented. By means of the structure, the safety and stability of a home elevator in the running process can be improved, accidents and injuries caused by sudden falling of the car and passengers in the car due to breakage of the cable are prevented, the state of the elevator after cable breaking is protected, and the injury degree to the passengers in the car is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of elevator equipment, and in particular relates to an auxiliary trigger device for a bottomless pit household elevator safety gear. Background technique [0002] With the continuous improvement of the economic level and the continuous advancement of urbanization and urbanization, people's residential forms are developing towards high-rise buildings and villas. In the construction process of high-rise buildings, elevator shafts are designed separately, most of which use traction elevators, with relatively complete and independent control and operation systems, and the development and application of related technologies are relatively mature; while in low-rise buildings such as villas, The storey height of villas is generally designed as two or three floors. Elevators are not designed in most villas, and because the entire equipment structure of the traction elevator is complex, it needs to be equipped with a ...
