Description
Technical field:
The present invention relates to a kind of machinery of cylinder cut, particularly a kind of lubricating system that should machinery.
Background technology:
Existing coal-winning machine, in the casing of its front arm (preceding cutting units), be provided with multilevel gear drive mechanism, in order to the transmission of power of prime mover (as motor) to cutting drum, its corresponding transmitted power is bigger, thereby the load of gear and bearing is also bigger, gear drive in service requires to have lubricating condition preferably, the lubricant method of existing equipment is, in the casing of front arm, store a certain amount of lubrication oil is arranged, mode with dip lubrication or splash lubrication is lubricated for gear drive, and under the normal running (operation) conditions, the lubricated of gear mechanism is no problem; But, coal-winning machine is in underground work, its residing coal bed texture is to have nothing in common with each other, when the work plane that runs into inclination, especially high_dipping face, and when the inclination angle is big; rocking arm must adapt to the inclination angle of work plane and upwards lift; the lubrication oil of storing in the rocker box is taken advantage of a situation in action of gravity and flowed downward; at this moment; in the rocker box near what gear of going up of cutting drum; Gear Planet Transmission and bearing are all away from the liquid level of lubrication oil in the case, and the fluid that splashes also can not spatter and these members, and gear and bearing almost are in unlubricated state operation; when coal-winning machine when above-mentioned environment carries out the long period operation; will influence the application life of gear and bearing, and may cause the damage of gear and bearing in the time of seriously, thereby bring adverse consequences difficult to the appraisal.
Summary of the invention:
Technical problem to be solved by this invention is, the enforced lubricating device of a kind of coal-winning machine cut driving section is provided, it can be after front arm angle of slope with respect to the horizontal plane surpasses setting value, still keep interior gear and the bearing of front arm to have good lubricating condition, to guarantee the normal operation of coal-winning machine near cylinder.
The technical scheme that the present invention solves the problems of the technologies described above employing is: the enforced lubricating device of coal-winning machine cut driving section includes the oil circulation system of front arm casing and hydraulic control, its hydraulic pump is connected in hydraulic motor through electromagnetic valve, the fluid motor-driven grease pump, be characterized in that the inner chamber in the upper end of front arm casing is connected with the fuel feed pump of oil circulation system, the other end of fuel feed pump is connected with grease pump, is connected with obliquity sensor on the electromagnetic valve of hydraulic control system.Coal-winning machine at work plane operation inclination angle, anxious inclination angle greater than when setting value, the obliquity sensor output signal, the hydraulic pump drive hydraulic motor of electromagnetic valve action hydraulic control system drives the grease pump gear fuel feeding of rocking arm casing upper end inner chamber forward.
The present invention carries out enforced lubricating by obliquity sensor control to gear, as long as the mining work face tilt reaches setting value, device just can be sent to lubrication oil upper end in the front arm casing, thereby guarantee in the front arm casing all to have good lubricating condition near the gear of cylinder and bearing (cut driving section by last what), fundamentally overcome legacy equipment and be in unlubricated defective at high_dipping face gear, bearing, prolong the working life of driving member, increase equipment reliability of operation improves the economic benefit of operation.
Description of drawings:
Fig. 1 is that coal-winning machine cut driving section is at level or gentle dip work plane schematic diagram.
Fig. 2 is that coal-winning machine cut driving section is at the high_dipping face schematic diagram.
Fig. 3 is the enforced lubricating device schematic diagram of coal-winning machine cut of the present invention driving section.
The specific embodiment:
With reference to Fig. 2,3, the enforced lubricating device of coal-winning machine cut driving section includes front arm casing 1, oil circulation system 2 and hydraulic control system 3.
The inner chamber of front arm casing 1 is provided with the cut driving section, what gear the cut driving section is by, compositions such as planetary gear transmission and corresponding bearing, front arm casing 1 inner chamber is a seal cavity, holding has the lubrication oil of certain liquid level, lubricated for each driving member with the immersion or the mode of splashing, the upper end 11 of front arm casing 1 is the position that cutting drum is installed, 12 of its bottoms and main body are hinged, front arm casing 1 can be around this pin joint swing under oil cylinder promotes, do the updip swing to adapt to the inclined cut, Fig. 1 is coal-winning machine cut driving section and front arm casing 1 working state schematic representation at level or gentle dip work plane, front arm casing 1 is raised at solid line position and begun cut, and is until finishing a cutter, return to level at head or tail cut driving section, shown in the notional line of Fig. 1, lubrication oil refluxes, and then next cutter of cut, so constantly lifts and sets level, about 30 to 40 minutes of every cutter cycle required time can guarantee the lubricated of each driving member basically.Fig. 2 is coal-winning machine cut driving section and front arm casing 1 working state schematic representation at high_dipping face, same front arm casing 1 is raised at solid line position and is begun cut, finish a cutter, can not be back to the level position at head or tail cut driving section, the inclination angle of working face of coal seam is β, the inclination angle of cut driving section is α, obviously the lubricant reservoir lubricating oil of front arm casing 1 inner chamber of this moment accumulates in bottom 12 always, if do not adopt technical scheme provided by the invention, the lubrication state of each driving member of nearly cutting drum will sharply worsen.
With reference to Fig. 3, the present invention is provided with oil circulation system 2, this system is provided with a fuel feed pump 21, the stretched through tank wall of upper end 12 of front arm casing 1 of fuel feed pump 21 1 ends, but each driving member of the nearly cutting drum of its mouth of pipe subtend (being each driving member of most significant end), the mouth of pipe also can be provided with spray structure, to form bigger fluid spray area; Can be connected with cooler 22 on the fuel feed pump 21, in the hope of gear or bearing are had better lubricated cooling effect; The import that the other end of fuel feed pump 21 is connected in grease pump 24 is connected in the inner chamber of the bottom 12 of front arm casing 1 through return line 23 and coarse filter, and grease pump 24 is driven by hydraulic motor 25.
The present invention also is provided with hydraulic control system 3, this system is provided with an obliquity sensor 31, this obliquity sensor 31 can be the potentiometer or the like of various types, it is designated as benchmark with static level or vertical base, its output signal changes with the size of inclination alpha or β (Fig. 2), when reaching setting value, the output electric weight of obliquity sensor 31 is opened the electromagnetic valve in the oil supply system 32; Electromagnetic valve 32 connects electronic hydraulic pump 33 respectively, hydraulic motor 25 and oil sump tank 34.
Duty of the present invention is:
The inclination alpha of front arm casing 1 is less than when setting value, the signal of telecommunication control electromagnetic valve 32 of obliquity sensor 31 is in position shown in Figure 3, the hydraulic oil of hydraulic pump 33 outputs directly returns fuel tank 34 through electromagnetic valve 32, and hydraulic motor 25 does not rotate, and oil circulation system 2 is in off working state;
