Lifting building machine

Abstract

The invention discloses a lifting building machine, and belongs to the technical field of building machinery. The machine comprises a lifting box for lifting and carrying and a plurality of connecting mechanisms, wherein the plurality of modularly assembled connecting mechanisms for improving the assembling efficiency of the lifting machine are mounted in an external stable frame, a toothed plate is spliced through the plurality of connecting mechanisms, and the toothed plate is engaged with a driving gear. According to the invention, through a designed purging assembly, when the driving mechanism drives a main shaft of a reduction gear box to rotate, a cam can extrude and drive an elastic air bag on one side to compress and blow air so as to realize air blowing and air injection purging of a purging nozzle on one side, and meanwhile, lubricating oil can be sprayed through one oil tank, and therefore, the self-cleaning and lubricating capacity to the toothed plate in the lifting process of the lifting box can be achieved, the wear-resisting and dust-proof capacity of the toothed plate can be effectively improved, the maintenance period of the toothed plate and a driven gear is effectively prolonged, and the use economic benefits after assembly are increased.

Description

technical field [0001] The invention belongs to the technical field of construction machinery, in particular to a lifting construction machinery. Background technique [0002] Construction machinery is a general term for mechanical equipment used in engineering construction. It generally includes the mechanical equipment necessary for loading and unloading and comprehensive construction projects required by construction. Generally, during construction, in order to better save hoisting capacity, it is generally necessary to use jacking machinery. Building materials or manual lifting start, which has higher stability and resistance than hoisting equipment. [0003] Due to the large lifting force of traditional lifting machinery, the lifting movement needs to be realized through the meshing transmission of the gear set and the rack. The friction between the rack and the gear is relatively large, and the amount of dust in the environment is large during construction on the const...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the friction between the rack and the gear is relatively large, and the amount of dust in the environment is relatively large during construction on the construction site, the gear and the rack are prone to wear due to friction after dust enters, which affects the The stability of transmission and lifting, and the rack and gear are disassembled and cleaned after assembly and wear, and replacement and maintenance require large-scale hoisting machinery. A kind of lifting construction machinery is proposed
