Mine sewage suction truck

Abstract

The invention discloses a sewage suction truck for mines. The sewage suction truck comprises a front frame, a rear frame, a traveling and hoisting joint control system and a stirring device. The front frame and the rear frame are hinged to each other, a tank is arranged on the rear frame, and lifting cylinders are arranged between the rear frame and the tank; the traveling and hoisting joint control system comprises an oil tank, a filter, a hydraulic pump, a safety valve, an anti-explosion electromagnetic valve, a manual reversing valve, an air-control switch, an explosion suppression power source, a gear selection cylinder, a gear selection reversing valve, an air pocket and a gear selection operating valve, and the stirring device comprises a supporting arm, a sewage suction pipe, a contraction and release cylinder, a rotary arm, a hydraulic motor, a connecting sleeve, a movable shaft and a stirring head. The sewage suction truck has the advantages that the sewage suction truck is provided with the traveling and hoisting joint control system, the sewage suction tank cannot be lifted by the lifting cylinders in sewage suction truck traveling procedures, and accordingly the sewage suction truck can safely pass low places such as underground air doors of coal mines; coal slimes under water sumps and sewage above the water sumps can be mixed with one another by the aid of the stirring device, and accordingly the coal slimes of lower layers of the water sumps can be effectively cleaned by the sewage suction truck.

Description

technical field [0001] The invention relates to a sewage suction truck. Background technique [0002] The coal mine underground water tank has a main tank and an auxiliary tank. When one water tank is cleaned, the other water tank can be used normally. Because a large amount of gushing water carries solid particles into the water tank, a large amount of coal slime and solid particles are deposited under the underground water tank. The solid particles and coal slime accumulated in the water tank must be cleaned regularly. Therefore it is very important to improve the efficiency of cleaning the water tank. The utility model patent specification authorized by China with the announcement number CN203175614U discloses a sewage suction truck for underground coal mines, including a front frame and a rear frame, the front and rear frames are hinged, the rear frame is provided with a sewage suction tank, and the rear frame There is a lifting cylinder between the sewage suction tan...

AI Technical Summary

Problems solved by technology

The above-mentioned utility model effectively solves the problem of cleaning the efficiency of the water tank, but the tank body is lifted during the driving process due to the misoperation of the manual control valve of the lifting cylinder during the driving process of the sewage suction truck, and the height is relatively high when passing through the downhole damper of the coal mine. Collisions can occur in low places, causing accidents

In addition, the above-mentioned utility model has a good cleaning effect on the sewage in the upper layer of the water tank when in use, but the coal slime in the lower layer of the water tank is not good in fluidity, so the use effect is not good when using the above-mentioned real model to clean the coal slime in the lower layer of the water tank
