Abstract
The utility model discloses a mine car loading and coal pressing device for coal mine inclined shaft lifting transportation. The mine car loading and coal pressing device comprises a fixed frame (1), an oil cylinder (2), a pressing plate (4) and a reversing valve (3), the fixed frame (1) is fixedly arranged on a top plate on the car dispatching side of a car loading point, the oil cylinder (2) is fixedly arranged in the fixed frame (1), the pressing plate (4) is fixedly arranged at the tail end of a plunger of the oil cylinder (2), one end of the reversing valve (3) is connected with the water inlet pipe of an underground dustproof pipeline, the other end of the reversing valve (3) is divided into two branches which are respectively connected with the oil cylinder (2), and water pressure is applied in a reversing mode to control the pressing plate (4) to lift or descend. The hydrostatic pressure of the dustproof pipeline is adopted as power, the plunger of the oil cylinder is controlled to push a coal pressing plate through the reversing valve, incompact coal arranged in a mine car is compacted, the phenomenon that the coal is scattered in the inclined shaft lifting transportation process is prevented from occurring to the mine car, and therefore derailing, off-track, collision, car running and other safety accidents are prevented from occurring to the mine car, the labor intensity of workers is reduced, production efficiency is improved, and the operation is safe.
Description
Technical field
The utility model relates to the mining equipment field, and device for coal is pressed in a kind of mine car entrucking for the coal mine inclined shaft hoisting transportation specifically.
Background technology
In a lot of coal mining, owing to limited by mining depth, most Coal Exploitations add the transportation mode of inclined shaft with vertical, and this mine car of just coal of exploiting field extraction need to being packed into, mention mine car through inclined shaft the lower parking lot of vertical, then from vertical, coal is mentioned to ground.In inclined shaft hoisting, because entrucking fills in the horizontal direction, more open again from pack into the coal of mine car of coal bunker, so, when lifting winch rises to direction of tilt by mine car by horizontal direction, part coal will scatter on track, cause the interior float coal of track too much, not only impact promotes safety, cause that derailing of mine car slides down, collision, derailing accident, and the float coal on the cleaning track also increased workman's labour intensity, also makes raising efficiency greatly reduce.
Summary of the invention
For solving the technical matters of above-mentioned existence, the utility model provides a kind of mine car entrucking for the coal mine inclined shaft hoisting transportation to press device for coal, before inclined shaft hoisting transportation by mine car in loose coal compacting, coal can not be scattered in transportation, avoid the safety misadventure of because of coal, being scattered and causing, enhance productivity.
For achieving the above object, the technical solution adopted in the utility model is as follows:
Device for coal is pressed in a kind of mine car entrucking for the transportation of coal inclined shaft hoisting, comprise fixed mount, oil cylinder, pressing plate and change-over valve, described fixed mount is fixedly installed on entrucking and points out on the top board of car side, described oil cylinder is fixed in fixed mount, described pressing plate is fixedly installed on the end of Cylinder Plunger, one end of described change-over valve is connected with the coolant inlet pipe of the dustproof pipeline in down-hole, and the other end is connected with oil cylinder respectively, and commutation applies rising or the decline of hydraulic pressure control pressing plate.
The hydrostatic pressure of the dustproof pipeline of the utility model utilization is done power, control Cylinder Plunger by change-over valve and promote coal pressing plate, the interior loose coal compacting of the mine car of packing into, avoided mine car to spread the phenomenon of coal in the inclined shaft hoisting transportation, in the process of pressing coal, the shower nozzle that the water discharged from oil cylinder is installed through coal pressing plate again is sprayed on the surface of coal in mine car, to prevent that mine car from occurring that in transportation coal dust flies upward, thereby avoid mine car to occur that derailing slides down, collide, sport car, the safety misadventures such as coal-dust explosion, alleviate labor strength, enhance productivity, and this device is simple and practical, safety of operation.
The accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in detail:
As shown in Figure 1, should press device for coal for the mine car entrucking of coal inclined shaft hoisting transportation, comprise fixed mount 1, oil cylinder 2 pressing plates 4 and change-over valve 3, described fixed mount 1 is fixedly installed on entrucking and points out on the top board of car side, described oil cylinder 2 is fixed in fixed mount 1, and described pressing plate 4 is fixedly installed on the bottom of oil cylinder 2 plungers, and an end of described change-over valve 3 is connected with the coolant inlet pipe of the dustproof pipeline in down-hole, the other end divides respectively two-way to be connected with oil cylinder 2, and commutation applies rising or the decline of hydraulic pressure control pressing plate 4.
The utility model is when work, fixed mount 1 is fixedly installed on to entrucking to be pointed out on the top board of car side, when the mine car 5 of filling coal runs to the below of pressing plate 3, operative employee's manual control change-over valve 3 is to the position of being pressed coal work, water in dustproof pipeline enters the interior promotion plunger of oil cylinder 2 by oil cylinder 2 tops and pressing plate 4 descends, the interior loose coal compacting of the mine car 5 of packing into, after compacting, operative employee's M/C change-over valve is to the position that promotes pressing plate 4, water in dustproof pipeline enters oil cylinder by oil cylinder 2 bottoms, promote the plunger upward movement, thereby promote pressing plate 4 to original position, the water earial drainage on oil cylinder 2 tops is in change-over valve 3 enters pressing plate 4 dust prevention sprinklers, dust-proof water is sprayed on to the surface of coal, completed the work of mine car pressure coal, when next mine car arrives pressing plate 4 below, the repetition aforesaid operations gets final product, simple and convenient.
In sum, after coal loading in mine car finishes, utilize the interior hydraulic pressure of dust removing down-hole pipeline as power, control pressing plate and press coal, after pressing coal to finish, water is done again dustproof the utilization, energy-conserving and environment-protective, need not provide power by unnecessary equipment, is applicable to the borehole operation application, after coal compacting in mine car, can the situation of coal not occur spreading with the motion of mine car, eliminate down-hole due to the various safety misadventures of spreading coal and causing, simultaneously, alleviated the work capacity that the underground labour clears up float coal, save manually, reduce costs, increase work efficiency.
Certainly; above-mentioned explanation is not the restriction to utility model; the utility model also is not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
