Crawler type gallery emergency rescue drainage pump truck

Abstract

The invention provides a crawler type gallery emergency rescue drainage pump truck to ensure drainage speed and drainage range and improve the emergency rescue drainage speed. The pump truck comprises a travelling mechanism on a main body, wherein the travelling mechanism consists of a crawler chassis, and a hydraulic system thereof; the crawler chassis is fixedly provided with a rotary platform and a rigid platform; a rotary motor, a front balance weight, a hydraulic telescopic arm and a cab are arranged on the rotary platform; a telescopic oil cylinder and a rigid telescopic oil cylinder are arranged in the hydraulic telescopic arm; the rigid telescopic oil cylinder and the telescopic oil cylinder perform fixed synchronous movement; an amplitude variation oil cylinder is arranged between the hydraulic telescopic arm and the rotary platform; the front end of the hydraulic telescopic arm is fixedly provided with a hydraulic portal; the hydraulic portal comprises a load-borne dropping portal, a dropping oil cylinder in an outer frame of the portal, and a tilting oil cylinder connected to a doorframe outer frame of the hydraulic portal and a mounting plate; two high-power pumps are fixed on the load-borne dropping portal; and the tilt angles of the pumps are controlled by controlling the tilt angle of the doorframe outer frame through the stretch of the tilting oil cylinder.

Description

technical field [0001] The invention relates to a crawler-type tunnel emergency drainage pump truck used for tunnel emergency rescue in coal mines, and belongs to the technical field of mechanical equipment. Background technique [0002] At present, the drainage of the mine is mainly carried out by the water pump and the pipeline connected with it. When a water seepage accident submerges the power supply equipment of the pump station and the drainage pump station cannot function or the water seepage speed is faster than the drainage speed of the pump station, other additional drainage methods are required. The main method of the existing technology is to transport the water pump to the underground with a winch, and then use manual transportation to transport the water pump to the drainage working face. Due to the large volume, heavy weight and the need for manual adjustment of the position of the water pump, it has installation problems. The problem of inconvenient handling...

Problems solved by technology

The main method of the existing technology is to transport the water pump to the underground with a winch, and then use manual transportation to transport the water pump to the drainage working face. Due to the large volume, heavy weight and the need for manual continuous adjustment of the position of the water pump, it has installation problems. The problem of inconvenient handling, connection and operation will affect the speed of mine emergency drainage and may cause heavy losses to the safety of life and property
