Problems solved by technology
Because some equipment is relatively heavy and very inconvenient to move, it can only be placed in rail cars to move with the mining progress. It is difficult for existing rail cars to meet this stop-and-go working state. It is difficult to move the car upwards, and the manpower is not enough to move the rail car uphill; therefore, there is an urgent need for a tractor that can stop and go with the progress of the excavation and can travel on the slope

The invention relates to a coal mine underground traction and transportation tool, and in particular relates to a rail clipping type hydraulic tractor. The technical problem of lacking of a device capable of conveniently stopping and traveling at any time along with a coal mining progress and capable of traveling on a ramp in the prior art is solved. The rail clipping type hydraulic tractor comprises two track vehicles in tandem, wherein a pushing jack is connected between the two track vehicles; the top of the movable end of the pushing jack is connected with one of the track vehicles; the fixed end of the pushing jack is connected with the other track vehicle; at least one rail clip matched with a rail is arranged on each of the left and right sides of the lower part of a frame of each track vehicle; a hydraulic station is arranged on one of the track vehicles; an oil outlet of an oil pump in the hydraulic station is connected with a propelling oil port of the pushing jack through an oil pipe to form an oil supply channel. The rail clipping type hydraulic tractor has the characteristics of labor saving, economic practicality and grade ability of 15 degrees or below, and is superior to a conventional winch in terms of all performances.
Description
technical field [0001] The invention relates to an underground coal mine traction transport tool, in particular to a rail-type hydraulic tractor. Background technique [0002] Under the coal mine, many equipment and personnel have to travel together with the progress of the mining. This kind of travel is characterized by slow movement and stopping from time to time. Because some equipment is relatively heavy and very inconvenient to move, it can only be placed in rail cars to move with the mining progress. It is difficult for existing rail cars to meet this stop-and-go working state. The car is just difficult to move upwards, and the manpower is not enough to move the rail car uphill; therefore, there is an urgent need for a tractor that can stop when walking with the progress of the excavation and can advance on the slope. Contents of the invention [0003] In order to solve the current technical problem of lacking a device that can stop and go conveniently with the prog...
