Problems solved by technology

The above-mentioned utility model effectively solves the problem of pipe transportation and installation in coal mines. However, during the use of the lifting pipe truck in coal mines, the driver will shift gears and drive while the carriage is still being lifted. Accidents may occur when the height is small
Secondly, there is also an accident caused by the rapid fall of the carriage under the action of gravity due to the damage of the hydraulic pipeline when the above-mentioned lifting and transporting vehicle is in the lifting state.
The above-mentioned lifting and transporting pipe vehicles have potential safety hazards, and the safety performance needs to be improved

Abstract

An elevating pipe conveying vehicle has a front frame and a rear frame, and a lifting seat is arranged on the rear frame. The elevating pipe conveying vehicle has a hydraulic system for lifting and prohibiting walking. Directional valve, second hydraulic pump, power cut-off valve, gear selection operating valve, forward gear clutch, reverse gear clutch and lift cylinder, gear selection operating valve includes joystick, oil outlet of the first hydraulic pump and manual directional valve The oil inlet port P of the manual reversing valve is connected to the port A and port B of the manual reversing valve respectively connected to the rod cavity and the rodless cavity of the lift cylinder, and the rodless cavity of the lift cylinder is connected to the control port K of the power cut-off valve The oil inlet port P and the execution port A of the power cut-off valve are respectively connected with the oil outlet port of the second hydraulic pump and the oil inlet port P of the gear selection operation valve, and the execution port A, Port B is connected to the forward gear clutch and the reverse gear clutch respectively. When the lift pipe transport vehicle is in the lifting state of the compartment, the vehicle cannot be shifted forward, which can ensure the safe running of the pipe transport vehicle.

Description

technical field [0001] The invention relates to a lifting pipe transportation vehicle. Background technique [0002] Pipelines are the most important transmission equipment in coal mines. They are responsible for the transmission of liquids such as watering and dust prevention, industrial drainage, compressed air, and gas such as nitrogen injection into coal seams. Pipelines include welded steel pipes, seamless steel pipes, glass steel pipes, plastic pipes, etc. Pipelines are widely installed underground in coal mines, generally tens of thousands of meters, or even hundreds of thousands of meters, so it is very important to improve the transportation and installation efficiency of underground pipelines. China's authorized announcement number is CN203175614U. The utility model patent specification discloses a kind of lifting and transporting pipe vehicle for underground coal mines, including a front frame and a rear frame, and the front and rear frames are hinged. A lifting ...
