Mining pneumatic stepless speed change concrete agitating conveying vehicle

Abstract

The invention discloses a mining pneumatic stepless speed change concrete agitating conveying vehicle. The mining pneumatic stepless speed change concrete agitating conveying vehicle comprises a frame (2), an agitating barrel (6) moveably arranged on the frame and a planetary reducer (5). One end of the agitating barrel (6) is connected with the planetary reducer while the other end of the agitating barrel is provided with a hopper (8). The frame is provided with a pneumatic motor (9) which is connected with the planetary reducer through a belt transmission mechanism (10). The frame is supported on a traveling mechanism (11) or an explosion-proof diesel locomotive (11). The traveling mechanism is driven by an explosion-proof traction locomotive. At first, the mining pneumatic stepless speed change concrete agitating conveying vehicle provided by the invention solves the explosion-proof problem under a shaft; second, the mining pneumatic stepless speed change concrete agitating conveying vehicle provided by the invention realizes stepless speed regulation, realizes rapid discharge by adjusting displacement at the inlet and outlet of a valve body of the pneumatic motor, meets the demand on the quantity of concrete for roadway construction, maintains continuous construction, improves the speed and the efficiency of roadway construction, and shortens the construction period; third, gas source under the shaft is abundant, electricity is replaced by wind power, and the production cost is reduced; and fourth, the mining pneumatic stepless speed change concrete agitating conveying vehicle provided by the invention can meet demands of construction of various mining roadways in the aspect of conveying way, and expands the application of the product.

Description

technical field [0001] The invention relates to a mine-used concrete mixing and conveying vehicle, in particular to a mine-used pneumatic continuously variable speed concrete mixing and conveying vehicle. Background technique [0002] Mining concrete mixer truck is mainly suitable for the construction of engineering sections such as coal mines and metal mines, railway tunnels, hydraulic culverts, military caverns, etc. It is a mechanical loading and unloading equipment for transporting concrete from the ground mixing station to the underground working surface. With the adjustment of the national industrialization policy, especially the national regulations on "equipment prohibited to be used in underground coal mines", the use of dry concrete sprayers in underground mines has been banned since 2012. [0003] At present, the mining concrete mixing and conveying truck used in the underground is powered by an electric motor to drive the planetary reducer to run, thereby driving...

AI Technical Summary

Problems solved by technology

This structure has two deficiencies: one is that the rotation speed of the motor under the rated voltage is constant, and the mine concrete mixer truck cannot be adjusted steplessly; the other is that when the mine concrete mixer truck is used in underground coal mines, the motor And electrical control must have good explosion-proof performance, so that the cost of explosion-proof products in terms of motors and electrical appliances is greatly increased, and it is easy to cause safety accidents. The truck works for a long time and cannot meet the technical requirements of underground construction
