Embodiment
By reference to the accompanying drawings, the specific embodiment of the present invention is described further:
Coal winning machine thin oil centralized lubrication system as shown in Figure 1, comprise fuel tank 1, gear lubrication pump 5, cooler 6, adjustable fuel-flow divider 8 and filtrating equipment, described filtrating equipment is connected with fuel tank 1, and gear lubrication pump 5 is connected with filtrating equipment, and cooler 6 is connected with the oil outlet of gear lubrication pump 5; The filler opening of gear lubrication pump 5 and oil outlet end are respectively connected with two 2/2-way explosion-proof solenoid valves, 2/2-way explosion-proof solenoid valve 4a, the 2/2-way explosion-proof solenoid valve 4b of gear lubrication pump 5 filler opening end are connected with filtrating equipment, the 2/2-way explosion-proof solenoid valve 4c of gear lubrication pump 5 oil outlet end, 2/2-way explosion-proof solenoid valve 4d are connected between cooler 6, adjustable fuel-flow divider 8, and the oil-feed port of adjustable fuel-flow divider 8 is provided with oil stream indicator 9; The oil outlet of described gear lubrication pump 5 is also connected with relief valve 7, and when pipeline blockage, lubricant oil is by relief valve 7 overflow.Wherein, using each rocking arm inner chamber as lubricating oil tank 1.
Described gear lubrication pump 5 is spline shaft type gear pump, the spline of gear lubrication pump 5 is connected with the fore side of rocker arm of coal mining machine the 3rd transmission shaft of processing internal spline, during the 3rd drive axis, driving gear lubricant pump 5 operates fuel feeding, 3rd transmission shaft fore side end cap adds O RunddichtringO and is connected with the adpting flange of gear lubrication pump 5, ensure that the sealing of rocking arm.Because the 3rd rotating speed of transmission shaft is determined, according to friction, vice president needs oil mass can select the gear lubrication pump of suitable fuel delivery, thus realizes automatic, fixed amount of oil.
The general bottom rocking arm inlet port adopting day-coal being arranged on to high speed chamber, is arranged on the bottom in low speed chamber to the rocking arm inlet port adopting lower floor's coal.Because coal winning machine rocking arm angle when heightening and move left and right coal mining can change, high, low speed chamber can be positioned at below liquid level successively.So add four 2/2-way explosion-proof solenoid valves (the 2/2-way explosion-proof solenoid valve a namely in figure, b, c, d) at the inlet port of gear lubrication pump 5, oil outlet, and on rocker arm of coal mining machine, be fixedly installed explosion-proof dip sensor 10 change to experience angle and send numerical variable signal, this signal controls the break-make of every part 2/2-way explosion-proof solenoid valve after PLC process, thus the inlet port of control gear lubricant pump 5 and the conversion of oil outlet.
Increasing cooler 6 at the oil outlet of gear lubrication pump 5 is for reducing oil temperature further, thus reduces the heating of rocking arm.
The little magnetic oil absorption filter 3 of volume and ball valve 2 is added as filtrating equipment near rocking arm inlet port, but consider and change filter element and maintenance is convenient, ball valve 2 will to be added in into filter side i.e. ball valve 2 and to be arranged at magnetic oil absorption filter 3 and to be connected with fuel tank 1 side.
Due to different to each friction pair fuel delivery, so add adjustable fuel-flow divider 8 at gear lubrication pump 5 oil outlet, increasing oil stream indicator 9 at each oil-feed port of adjustable fuel-flow divider 8 can metered fuel charge amount accurately intuitively, by observing each oil stream indicator 9 and adjusting the accurate oil supply that adjustable fuel-flow divider 8 realizes each friction pair.
Therefore, the present invention utilizes rocking arm inner chamber as lubricating oil tank 1, ball valve 2 is utilized to realize the convenience of more renew cartridge and maintenance, magnetic oil absorption filter 3 is utilized to filter out the lubricant oil with metal granule and other impurity from fuel tank 1 sucking-off, utilize rocking arm fore side the 3rd transmission shaft direct drive gear lubricant pump 5 fuel feeding, when oil feed line blocks, relief valve 7 is utilized to carry out overflow; Utilize cooler 6 cooling oil temperature to reduce the heating of rocking arm, utilize explosion-proof dip sensor 10 to experience angle change and send numerical variable signal to control the break-make of 2/2-way explosion-proof solenoid valve thus the inlet port of control gear lubricant pump 5 and the conversion of oil outlet, adjustable fuel-flow divider 8 and oil stream indicator 9 is utilized to carry out the lubricants capacity that reasonable distribution enters variant friction pair, utilize nozzle 11 that lubricant oil umbrella is sprayed gears meshing face, thus realize automatically, quantitatively, accurately lubricating each heavy duty friction pair of rocker arm of coal mining machine.
Specific works process of the present invention is:
As Fig. 1 show position time, explosion-proof dip sensor 10 nil signal exports, and a, b, c, d tetra-explosion-proof solenoid valves all must not electricity, and in rocking arm, lubricant oil carries out free circulating cooling.
As Fig. 2 show that rocking arm heightens α angular orientation time, explosion-proof dip sensor 10 has digital signal 1 to export, b, c two explosion-proof solenoid valves obtain electric closedown; in rocking arm lubricant oil by bottom, high speed chamber through not electric 2/2-way explosion-proof solenoid valve a sucks gear lubrication pump 5, through not electric 2/2-way explosion-proof solenoid valve d to being in the low speed chamber gear of ullage, bearing carries out pressure spray lubrication.
As Fig. 3 show that rocking arm heightens β angular orientation time, explosion-proof dip sensor 10 has digital signal 2 to export, a, d two explosion-proof solenoid valves obtain electric closedown; in rocking arm lubricant oil by bottom, low speed chamber through not electric 2/2-way explosion-proof solenoid valve b sucks gear lubrication pump 5, through not electric 2/2-way explosion-proof solenoid valve c to being in the high speed chamber gear of ullage, bearing carries out pressure spray lubrication.
