Positioning device and positioning method of lift car

Abstract

The invention relate to a positioning device and a positioning method of a lift car. Positioning mechanisms are arranged at one side of the lift car and each positioning mechanism comprises two sets of positioning assemblies; each set of the positioning assembly comprises a first positioning bracket; one end of the positioning bracket is detachably and fixedly connected with one corresponding side of a guide rail through a compacting code component; one part of the other end of the positioning bracket, which is close to the position of the end part, is provided with an axial adjusting hole along an axial direction; a second positioning bracket, an adjusting bolt and a locking nut matched with the adjusting bolt are arranged; one end of the second positioning bracket is ejected against the radial side face of a corresponding stand column; and the end part of the adjusting bolt sequentially penetrates through the locking nut, the axial adjusting hole of the first positioning bracket and a screw hole at the other end of the second positioning bracket to be ejected against the axial side face of the corresponding stand column. Compared with the prior art, the positioning precision of the lift car is improved; and mounting and operation steps of connecting parts including a safe clamp, a guide boot, a buffering beam and the like which are related to the lift car are simplified, and the commonality of a tool for positioning a lift car is improved.

Description

technical field [0001] The invention relates to a positioning device for an elevator car and a positioning method thereof. Background technique [0002] At present, since the car of most elevators is not precisely positioned in advance during the elevator installation process, the associated components (such as: safety gear, guide shoes, buffer beams, etc.) cannot be in a stable state during installation, resulting in Time-consuming and labor-intensive, the installation efficiency is low. Especially when the safety gear parts are installed or maintained and replaced, because the position of the car and the guide rail is not fixed, the safety gear is in an active state, and it is necessary to hold the heavy safety gear by hand and laboriously adjust the distance between the safety gear wedge and the guide rail. The distance is very labor-intensive, and the distance between the positioning safety gear wedge and the guide rail cannot be accurately adjusted, which may cause saf...

[0002] At present, since the car of most elevators is not precisely positioned in advance during the elevator installation process, the associated components (such as: safety gear, guide shoes, buffer beams, etc.) cannot be in a stable state during installation, resulting in Time-consuming and labor-intensive, low installation efficiency

Especially when the safety gear parts are installed or maintained and replaced, because the position of the car and the guide rail is not fixed, the safety gear is in an active state, and it is necessary to hold the heavy safety gear by hand and laboriously adjust the distance between the safety gear wedge and the guide rail. It is very labor-intensive, and the distance between the wedge and the guide rail cannot be adjusted accurately, which may lead to misoperation of the safety gear

After the safety gear is installed, the guide shoe needs to be adjusted and positioned. Due to the error of manual positioning, it is necessary to move the guide shoe seat by loosening three tightening one (fixing bolts of the guide shoe seat) to meet the installation requirements, and it must be matched many times. The safety gear and guide shoe can only be installed accurately after adjustment, and the installation and maintenance work efficiency is low
