Technical Field

[0001] The utility model relates to the technical field of underground refueling in mines, in particular to a movable underground quick refueling device. Background Art

[0002] The underground equipment in the mine includes scrapers, underground dump trucks, skid trolleys, tunneling trolleys, trackless vehicles, etc. The gear oil of the chassis drive axle and wheel reducer must be replaced every 1,000 hours. The refueling tools currently used are 10L iron barrels and small refueling pumps. Because the viscosity of gear oil is thicker than other oils, every time the oil is replaced, the equipment maintenance worker needs to cooperate with two people to maintain the chassis, replace the front and rear drive axle differentials and wheel reducers to add gear oil. One person stands in the trench and holds the oil extraction pipe with his hand, and the other person shakes the oil pump over and over above the trench until the parts reach the qualified oil level. This is time-consuming and labor-intensive, and it is very easy to cause the gear oil to spill, causing waste and polluting the workplace.

[0003] A more prominent Chinese patent with publication number CN205313068U discloses a pneumatic gear oil and engine oil refueling device: a hollow oil storage tank is provided inside; a refueling pipe connected to the cavity in the oil storage tank is provided on the oil storage tank, and a refueling control valve is also provided on the refueling pipe; an oil drain pipe connected to the cavity in the oil storage tank is also provided at the bottom of the oil storage tank, and an oil drain control valve is also provided on the oil drain pipe; an air intake pipe connected to the cavity in the oil storage tank is also provided on the oil storage tank, and an air intake control valve is also provided on the air intake pipe. Compared with the traditional refueling method, this refueling device overcomes the problems of high viscosity of gear oil, difficulty in flowing, and susceptibility to external temperature and environment, and solves the problem that refueling requires the cooperation of two workers; however, this refueling device has a complex structure, occupies a large space, is inconvenient to move, and the device of this scheme relies on an air source when in use, is costly, and is inconvenient to use.

[0010] Furthermore, based on the above core technical solution, the hard container is cylindrical.

[0011] Furthermore, based on the above core technical solution, the material of the hard container is metal, and the material of the cover plate is metal.

[0012] Furthermore, based on the above core technical solution, a hanging ring is provided on the support portion, a hanging ring is provided on the bottom of the hard container, and hooks are provided at both ends of the spring.

[0013] Furthermore, based on the above core technical solution, the spring is a stainless steel tension spring.

[0014] Furthermore, based on the above core technical solution, a plurality of supporting legs are provided under the base plate.
