Through opening the oil filler capping that is provided with on the casing, the operator with oil can or similar container to the oiling of lubricant oil storage chamber;
Through opening the oil filler capping that is provided with on the casing, the operator with manual pump to the oiling of lubricant oil storage chamber.
In the coal winning machine operation process, the fully mechanized mining face dust is bigger, and water is also more; When existing oiling is operated, must open the oil filler capping, unlimited oil filler makes dust and water electrode be prone to get into the lubricant oil storage chamber; Thereby make cavity space or lubricant pollution; Its result will influence the working life of members such as power train middle gear, bearing, sealing, even cause the catastrophe failure of power train, the normal operation that jeopardizes coal winning machine; Simultaneously, at thin seam working surface, the spatial altitude between coal mining fuselage and hydraulic support or the roof is very low; The operator carries out the oiling operation in small space, not only working efficiency is extremely low, and labor intensity is also very big; Especially under the situation of top board condition difference; Oiling operation also jeopardizes personal safety, above-listed all factors, and the dealer earnestly hopes in a hurry and has solved the variety of problems that the oiling of existing power train profit oil pocket brings.
The model utility content:
The utility model technical problem to be solved is: provide a kind of coal winning machine to concentrate oil-filling device; It can reduce the pollution of winning machine cutting part and tractive unit lubricant oil storage chamber; Can reduce the labor intensity of lubricant oil storage chamber oiling operation, improve the working efficiency and the Security of oiling operation.
The technological scheme that the utility model solves the problems of the technologies described above employing is:
Coal winning machine concentrates oil-filling device to include the height-adjusting system major loop; Be characterized in: coal winning machine concentrates oil-filling device to have one or two three-way diverter valve; This two-bit triplet selector valve is connected with height-adjusting system major loop and pump motor sub-assembly respectively; This pump motor sub-assembly is connected with filler tank and rotary valve respectively, and this rotary valve has one group of oil filler pipe, and each oil filler pipe is connected with corresponding lubricant oil oil storage chamber respectively.During the oiling operation; Control two-bit triplet selector valve; The oil hydraulic motor and the height-adjusting system major loop of pump motor sub-assembly are connected, utilized the hydraulic oil oil return energy drives oil hydraulic motor of this height-adjusting system major loop, oil hydraulic motor driven gear oil pump is assigned to the lubricant oil oil storage chamber that each needs oiling through rotary valve.
The utility model make winning machine cutting part and tractive unit each independently the oiling of lubricant oil oil storage chamber be in the pipe-line system of a sealing, to carry out; Fundamentally overcome the difficult problem that traditional oiling mode produces lubricant pollution; The oiling operation of the utility model is to utilize the existing height-adjusting system major loop of coal winning machine oil return energy; And under the centralized control condition, carry out oiling, not only reduce the labor intensity of oiling operation significantly, and can obviously increase work efficiency and Security; Device adopts existing product to form better simply injection system, has good economic benefit.
Description of drawings:
Fig. 1 is that the utility model coal winning machine is concentrated the oil-filling device structural representation.
Embodiment:
With reference to Fig. 1, coal winning machine concentrates oil-filling device to include height-adjusting system major loop 1, two-bit triplet selector valve 2, pump motor sub-assembly 3, filler tank 4 and rotary valve 5.
Height-adjusting system major loop 1; It is the existing height-adjusting system hydraulic drive circuit of coal winning machine; This loop includes main pump 11, master control valve 12, return tube 13 and relevant fuel tank, filter, main pump drive motor and associated pipe and annex; Usually this loop structure is identical with existing technology, and the hydraulic system oil return of its major loop is direct oil sump tank.
Two-bit triplet selector valve 2 can adopt manually operated valve, and the filler opening of this two-bit triplet selector valve 2 is communicated with the return tube 13 of height-adjusting system major loop 1 master control valve 12; The oil outlet of this two-bit triplet selector valve 2 is communicated with the oiler of the oil hydraulic motor 31 of pump motor sub-assembly 3, and the return opening of two-bit triplet selector valve 2 is communicated with the fuel tank of height-adjusting system major loop 1.
The axle of gear oil pump 32 is the output shafts that are serially connected in oil hydraulic motor 31, and the oil hydraulic motor 31 of rotation can drag gear oil pump 32 operations; The oil pump suction tube of gear oil pump 32 is communicated with filler tank 4, and the oil pump feed pipe 34 of gear oil pump 32 is communicated with the valve filler opening of rotary valve 5; When gear oil pump 32 operations, can be with in the lubricant oil suction pump in the filler tank 4, the oil pump feed pipe 34 through gear oil pump 32 infeeds rotary valve 5 again.
