Motor-driven elevator rope gripping device capable of automatic resetting

Abstract

The invention discloses a motor-driven elevator rope gripping device capable of automatic resetting, which comprises a main body base, a driving motor disposed at one side of the main body base, and a driving movable plate and fixed plate disposed in the main body base. The motor-driven elevator rope gripping device capable of automatic resetting is characterized in that a spring, guide pillars, a lead screw and a lead screw nut are fixedly disposed between the main body seat and the driving movable plate; the guide pillars are disposed around the lead screw; guide sleeves sleeve the guide pillars; a brake pad is disposed between the driving movable plate and fixed plate; a brake pad baffle plate is disposed on the main body seat, and fixed by means of a bolt; the fixed plate is intended to be separated from a steel wire rope under the action of the lead screw to achieve resetting. The motor-driven elevator rope gripping device capable of automatic resetting is simple in structure, relatively low in cost, and convenient to mount; repair and maintenance of the device can be completed directly in a machine room; the device is driven by the driving motor, and thus has a short stroke with no impact force generated, and is fast in dynamic response and low in operation noise.

Description

technical field [0001] The invention relates to a motor-driven elevator rope clamping device with automatic reset. Background technique [0002] The installation and maintenance of the traditional elevator rope clamping device needs to go to the bottom of the elevator pit, and it is extremely unsafe to work under the car. It adopts a mechanical method, the stroke is large, and it will make a loud noise when it moves; the brake pads of the traditional elevator rope clamping device When wearing, it is necessary to manually adjust the support screws on the static plate, and it is very inconvenient to go into the pit for operation, and the impact force of the traditional rope clamp is relatively large, which will cause serious damage to the steel wire rope of the elevator. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a motor-driven elevator rope clamping device with automatic reset. [0004] A motor-driven elevator rop...
