Telescopic vertical motion box guide mechanism

Abstract

The invention discloses a stretchable vertical movement box body guide mechanism. The guide mechanism comprises a pipeline used for accommodating a box body to do vertical movement and a guide devicearranged on the box body and used for guiding the box body to do vertical movement in the pipeline, and the guide device is of a stretchable structure and comprises guide rails arranged on the side wall surfaces of the box body, at least one wedge-shaped sliding block which is arranged on the guide rails and can slide along the guide rails, guide balls abutting against the wedge-shaped sliding blocks and cooperating with the wedge-shaped sliding blocks to form wedge-shaped adjusting mechanisms, and guide ball restraining devices arranged on the outer sides of the guide balls and used for restraining the guide balls to move only in the directions perpendicular to the side wall surfaces of the box body. According to the stretchable vertical movement box body guide mechanism, the wedge-shapedsliding blocks are driven to slide along the guide rails, so that the guide balls move in the directions away from or close to the side wall surfaces of the box body, then guiding is realized by abutting against the inner wall of the pipeline of the guide balls during vertical movement, or the guide balls are contracted to be away from the inner wall of the pipeline when the box body is in and out of a vertical track, and then interference with racks on the inner wall of the pipeline can be avoided.

Description

technical field [0001] The invention relates to a guiding mechanism, in particular to a retractable vertically moving box guiding mechanism. Background technique [0002] Common box-type vertical motion equipment includes elevators, automatic storage, etc. This type of device is generally driven by drag or chain. Its main characteristics are that the box is large in size and uneven in weight distribution, which may easily cause unstable vertical crawling motion. If it is light, it will accelerate the wear of the transmission chain, and if it is heavy, it will cause a major accident. . The guide shoe is an important part of the safe operation of the elevator. Under the cooperation of the guide shoe and the guide rail, the elevator runs along the predetermined route track to achieve the purpose of transporting people and goods. At present, the guide shoes used in the elevator industry are mostly pure sliding guide shoes, which are simple to manufacture and low in cost, but t...

AI Technical Summary

Problems solved by technology

For this kind of crawling equipment that needs to enter and exit the vertical track, the guide device protrudes from the outside of the box and needs to abut against the inner wall of the pipe to achieve guidance. Therefore, when entering the vertical track, the existing fixed guide device must It will interfere with the rack on the inner wall of the pipe, affecting its smooth entry into the pipe

On the other hand, the pipeline wall circuit is complicated, and the guiding precision and cleanliness are also required to be high. The pure sliding guide rail is not suitable for this type of transport vehicle due to its own defects.
