Hydraulic pole climbing apparatus

Abstract

The invention discloses a hydraulic pole climbing device, which belongs to the field of building auxiliary equipment. The hydraulic pole climbing device comprises a vertical climbing column with a rectangular section, two ratchet boxes are nested on the climbing column sequentially, bi-directional oil cylinders are symmetrically arranged between both sides of the two ratchet boxes left and right, bodies of the bi-directional oil cylinders are hinged with one ratchet box, plungers of the bi-directional oil cylinders are hinged with the other ratchet box, guiding blocks are respectively arranged at the four corners of the climbing column in the two ratchet boxes, a plurality of footboard blocks are symmetrically arranged at both sides of the climbing column, ratchets are symmetrically hinged at both sides of the climbing column in the two ratchet boxes, when the upper ends of the ratchets rotate to the climbing column along the hinging point, the upper ends of the ratchets butt against the lower ends of the corresponding footboard blocks, arc grooves are arranged on the ratchet boxes, spring pin axles inserted into the arc grooves are disposed on the ratchets, and springs pulling the upper ends of the ratchets towards the climbing column are arranged at the extended ends of the spring pin axles. When the device is in operation, the pole climbing and the load climbing can be enhanced step by step, and the device can be used for lifting templates, large-scale elevated devices, steel structures and building components and the like.

Description

technical field [0001] The invention relates to an auxiliary device used in building construction, in particular to a power mechanism used for lifting templates and hanging platforms in sliding formwork and climbing formwork. Background technique [0002] When pouring concrete in the construction field, pre-formwork is required, that is, the formwork is pre-fixed on the outer periphery of the steel cage, poured after fixing, and the formwork is removed after the cement is solidified, and then the next position is erected. The demolition and formwork require a lot of money Time, also need a large amount of supports to support and fix the formwork when the formwork is erected, therefore, its consumables are many, and construction progress is slow. In the prior art, there is a dual-function hydraulic jack for lifting mold and lifting rod (this application is called: dual-function jack), the patent number is ZL200420080879.7, the upper cylinder, the lower cylinder and the two-wa...
