Self-locking structure for elevator stall used in field of building automation engineering

Abstract

The invention discloses a self-locking structure for elevator stall used in the field of building automation engineering and relates to the technical field of building automation engineering. The self-locking structure comprises a mounting seat, wherein the front of the mounting seat is fixedly connected with a positioning seat; positioning cavities are formed in the positioning seat; the interiors of the positioning cavities are movably connected with self-locking blocks; self-locking mechanisms are arranged in the positioning cavities; the interior of the positioning seat is movably connected with a main winch; the front of the main winch is fixedly connected with an auxiliary winch; the outside of the auxiliary winch is fixedly connected with stopping blocks; and the back of the positioning seat is fixedly connected with a locating ring I. The self-locking structure for elevator stall used in the field of building automation engineering adopts the design of self-locking for stall, so that when an elevator breaks down to fall in a stalled manner, self-locking can be achieved timely through the structural characteristics of the self-locking structure to prevent an elevator car from falling rapidly, thus avoiding safety accidents caused by the stall of the elevator and effectively improving the safety of passengers in the elevator; and therefore, the self-locking structure is more in line with the requirements of building automation.

Description

technical field [0001] The invention relates to the technical field of building intelligent engineering, in particular to an elevator stall self-locking structure used in the building intelligent engineering field Background technique [0002] Building intelligent engineering is an industry that has gradually emerged with the development of information and automation technology in recent years. Its main content is to increase the intelligence, informatization and operability of equipment in buildings, and to promote the safety and environmental protection of building equipment and the whole. . [0003] As an important part of building intelligent engineering, elevator not only plays a major role in the overall structure of the building, but also greatly facilitates people's daily travel. In the prior art, the elevator generally uses a winch to retract the hinged steel cable to lift the elevator car body. The safety measure corresponding to the elevator is generally to insta...

Problems solved by technology

Since the braking method is relatively simple, it cannot better deal with sudden accidents, and there are certain hidden dangers

At the same time, the existing self-locking devices are generally triggered by mechanical induction, the response is relatively slow, and there may be problems with braking not in time, causing serious personnel and property losses, and posing a great safety hazard
