Anti-pinch device of open-type lift car

Abstract

The invention discloses an anti-pinch device of an open-type lift car. The anti-pinch device comprises the open-type lift car, wherein the open-type lift car comprises a bottom plate and a back plate,a touch plate assembly is arranged between the periphery of the bottom plate and a hoistway and can move relative to the bottom plate in the vertical direction, a link mechanism connected with the touch plate assembly and an elastic piece connected with the link mechanism are arranged on each side of the back plate, limiting plates are arranged on two sides of the touch plate assembly respectively, and micro-switches connected with a control system and matched with the corresponding limiting plates are arranged on two sides of the back plate respectively. After external force is exerted on the touch plate assembly, the touch plate assembly can move downwards relative to the bottom plate and draw the elastic pieces until the limiting plates trigger the corresponding micro-switches, and thecontrol system controls the open-type lift car to stop moving; after the external force disappears, the touch plate assembly returns to the original position upwards under the function of the elasticpieces and torsional spring assemblies. The anti-pinch device of the open-type lift car is simple, reliable, convenient to use, high in safety and capable of guaranteeing safety of passengers.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an open car anti-pinch device. Background technique [0002] As a common carrier for home elevators and villa elevators, open elevators have the advantages of simple appearance, simple structure, and high space utilization, and are favored by consumers. Compared with the closed car of the traditional elevator, the open elevator has its own unique car structure. There are no car walls on the left, right and front sides of the car, and a certain gap is maintained between the car bottom and the hoistway wall. During the operation, when the car bottom and the hoistway wall are in relative motion, this gap is likely to cause the passengers to be pinched. In order to solve this safety problem, it is necessary to develop a car anti-pinch device to ensure the safety of the elevator passengers. Contents of the invention [0003] In order to overcome the deficiencies of the prior art...
