Height-adjustable scaffold for house construction

Abstract

The invention relates to the technical field of scaffolds, and provides a height-adjustable scaffold for house construction. The scaffold comprises a movable base, a shear fork lifting mechanism, a supporting mechanism, an operation basket, an extension mechanism A and an extension mechanism B; and the shear fork lifting mechanism is slidably connected to the inner side of the movable base and theinner side of the supporting mechanism. Two driven gears are driven by a gear rod to be in meshing transmission with a driven rack A and a driven rack B, so that the extension mechanism A and the extension mechanism B are driven to extend while a shear fork rod lifts the operation basket, and the purpose of expanding the operation space of an operator is achieved; and by means of the design, theworking space of the operator can be expanded while the whole device is not moved, and meanwhile the device has the advantages of being capable of moving with a smaller size, simple in structure, highin working efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of scaffolding, and more specifically relates to a height-adjustable scaffolding for building construction. Background technique [0002] Scaffolding is a working platform set up to ensure the smooth progress of various construction processes. According to the erection position, it can be divided into external scaffolding and internal scaffolding; according to different materials, it can be divided into wooden scaffolding, bamboo scaffolding and steel pipe scaffolding; according to the structure form, it can be divided into vertical pole scaffolding, bridge scaffolding, portal scaffolding, suspension scaffolding Hanging scaffolds, pick-up scaffolds, and climbing scaffolds, and most of the existing scaffolds are integrally welded structure designs, so there is a purpose that the height cannot be adjusted for use during use. [0003] For example, the Chinese invention patent with the application number CN2014...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the present invention provides a height-adjustable scaffolding for building construction, so as to solve the problem that the existing lifting scaffolds cannot effectively protect the operators on the scaffolding during lifting and lowering in the actual application process, and The overall structure of the frame cannot be expanded with the lifting of the frame, the frame is inconvenient to move, the height of the frame itself is fixed, and a support frame needs to be attached to the upper building to assist in lifting, etc.
