Limiting device for guide frame

Abstract

The invention discloses a limiting device for a guide frame, which is used for guiding and limiting a crane. The limiting device for the guide frame consists of the crane, a limit stop, guiding shafts and balance weight blocks, wherein the limit stop is positioned at the topmost end of the guide frame device; the two symmetrical guiding shafts in a vertical direction are arranged on two sides of the limiting device for the guide frame; two balance weight blocks are arranged at the bottom of the two sides of the two limiting devices for the guide frame; and the crane is connected with the guiding shafts through a linear bearing. The device has the advantages that: the problems of guiding and limiting function of the crane are solved effectively; the safety factor is greatly increased; continuous and stable production is ensured; and the device has a simple structure and is easy to manufacture.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a guide frame limiting device used for guiding and limiting a lifting frame. Background technique [0002] The guide part of the original equipment is not a linear bearing, but a guide sleeve (which is relatively difficult to process). During the lifting process of the lifting frame, the guide shaft and the guide sleeve are in contact with the entire surface, plus processing and installation reasons (both It is necessary to ensure concentricity and verticality), which greatly increases the occurrence of pauses and stagnation. If the lifting frame cannot rise to the position, the template may roll out from the gap between the limit stop and the lifting frame, causing damage to the slab, and it is more likely that the template will hit people. [0003] Problems such as low production efficiency and low safety factor caused by the original equipment lifting frame running stop, ja...

Problems solved by technology

If the lifting frame cannot rise to the position, the template may roll out from the gap between the limit stop and the lifting frame, causing damage to the slab, and it is more likely that the template will hit people

[0003] Problems such as low production efficiency and low safety factor caused by the operation stoppage, jamming, and inaccurate stop positioning of the original equipment lifting frame have become problems that need to be solved urgently in the industry
