A lifting construction machine

Abstract

The invention discloses an elevating construction machine, which belongs to the technical field of construction machinery, and comprises an elevating box for elevating and carrying loads and a plurality of connection mechanisms, and a plurality of modularly assembled connection mechanisms for improving the assembly efficiency of the elevating machinery are installed on the outside In the stable frame, toothed plates are spliced ​​through multiple connecting mechanisms, and the toothed plates are meshed with driving gears. In the present invention, through the design of the purge assembly, when the drive mechanism drives the main shaft of the reduction gear box to rotate, the cam can squeeze and drive the elastic air bag on one side to compress the blowing air, thereby realizing the blowing and air blowing of the purge nozzle on one side, and At the same time, lubricating oil can be sprayed through an oil tank, and then the self-cleaning and lubricating ability of the tooth plate during the lifting process of the lifting box can be realized, which can effectively improve the wear-resistant and dust-proof ability of the tooth plate, and effectively prolong the contact between the tooth plate and the driven gear. The extension of the maintenance cycle increases the economic benefits after assembly.

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
