Scaffold with adjustable height and size

Abstract

The invention discloses a scaffold with the adjustable height and size. The scaffold with the adjustable height and size comprises a support platform, a scaffold platform, a support penetrating through the scaffold platform at intervals and a ladder hinged to the left end of the support platform; a driving gear and a first driven gear are arranged at the upper end of the support in a rolling mode,the first driven gear is engaged with the driving gear, a driven gear set is arranged in the middle of the upper surface of the support platform, and comprises two second driven gears horizontally arranged in an engaged mode, two racks are arranged in the middle of the lower surface of the scaffold platform, and are respectively connected with the two second driven gears in an engaged mode, the first driven gear and one of the second driven gear are connected by chain engagement and transmission, a storing groove is formed in the right side of the bottom of the scaffold platform, and is slidably connected with a plate surface in a sleeved mode, the front and rear sides above the scaffold platform are provided with guardrails, and the contrary sides of the upper end of the guardrails are correspondingly provided with storage frames. The scaffold with the adjustable height and size has the beneficial effects of effectively solving the problem of difficult height adjustment of the scaffold, expanding a platform area without occupying space resources, and enhancing the practicability of the scaffold.

Description

technical field [0001] The invention relates to a construction machine, in particular to a scaffold whose height and size can be adjusted. Background technique [0002] At present, scaffolding is mainly used in building construction. Most scaffolding is an assembled structure, and the height cannot be adjusted directly. Increased thereupon, inconvenient to use and store. Contents of the invention [0003] In view of the above existing problems, the present invention proposes a scaffold that can be adjusted in height and size. The present invention uses manual manpower to freely and conveniently adjust the height of the scaffold, which solves the problem of difficulty in adjusting the height of the scaffold, and can freely expand the table, which is convenient Safety. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A scaffold that can be adjusted in height and size, including a supporting platform, a...
