A pneumatic truck crane for principle demonstration

Abstract

The invention discloses a pneumatic automobile crane used for principle demonstration, belonging to the hoisting machinery field, and comprises an automobile chassis, a cargo boom, a revolution mechanism, a hoisting mechanism and a luffing mechanism. The automobile chassis controls front axle deflection steering through a steering cylinder, and provides rear axle driving power through a gas motor; the vehicle frame of the automobile chassis is also provided with two sets of hoisting supporting legs. The revolution mechanism realizes the rotation of a revolving platform through a swing cylinder; the cargo boom is installed on the revolving platform, and a cylinder controls the telescoping of the cargo boom; the hoisting mechanism utilizes a pneumatic motor to drive a reel to fold and unfold a steel wire rope to hoist cargoes; the luffing mechanism controls the inclination angle amplitude of the cargo boom through a luffing cylinder. The pneumatic automobile crane utilizes pneumatic power as the power source of an automobile crane, simulates and manufactures the demonstration model of the automobile crane, more visually displays the work principle of the automobile crane, facilities on-site teaching and principle demonstration, and plays a good role in researching the automobile crane.

Description

technical field [0001] The present invention relates to a truck crane, and more particularly, to a pneumatic truck crane for principle demonstration. Background technique [0002] Hoisting machinery (crane) is an important means of transportation in the national production and manufacturing process. It is a kind of machinery that can move horizontally and vertically lift objects within a certain range; it can not only reduce physical labor, but also greatly improve labor productivity. The truck crane is a machine that combines the lifting device with the chassis of the car. It has the characteristics of cyclic operation and intermittent action. It is mostly used for tasks that are difficult to complete by manpower. It is mainly used in engineering construction, general construction engineering teams, and construction industries. , Power installation departments, etc. all need truck cranes to assist in construction. [0003] Truck cranes play a very important role in enginee...

AI Technical Summary

Problems solved by technology

However, truck cranes are bulky and complex in structure, and most of them use complex hydraulic systems as the lifting power source. Therefore, in order to better study truck cranes, it is necessary to model truck cranes to facilitate teaching demonstrations

The working principle of the pneumatic transmission system is similar to that of the hydraulic transmission system. The pneumatic transmission system can be used instead of the hydraulic transmission system as the power source of the modeled truck crane to solve the problems of hydraulic oil leakage pollution, system complexity, and Problems such as high cost and inconvenient operation
