Abstract

The invention discloses an auxiliary trigger device for a bottomless pit domestic elevator safety gear, which comprises a trigger component, a locking component and a connecting rod component. Wherein, the trigger assembly includes a tension wheel and an elastic reset member, and the cable is pressed on the tension wheel so that the elastic reset member is compressed in an energy storage state, so that the locking assembly is in a non-braking position; the cable is separated from the tension wheel so that The elastic return part releases the stored elastic potential energy, and then makes the locking assembly switch from the non-braking position to the braking position, thereby realizing the clamping of the locking assembly on the guide rail, and preventing the car from suddenly falling due to the breakage of the cable. This structure can improve the safety and stability of the home elevator operation process, prevent accidents and injuries caused by the sudden fall of the car and the occupants in the car due to broken cables, and protect the state of the elevator after the rope is broken, greatly reducing The degree of injury to the occupants inside the car is determined.

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 ...
