Background technology
Traditional mining down-hole slat conveyer; Its power system is by the driven by motor retarder; Retarder drives the sprocket shaft group work of equipment, because the sprocket shaft group needs frequent speed governing and frequent start-stop, the motor frequent start-stop is big to the impact of electrical network; And the high pulling torque during start and stop causes very big impact shock to the sprocket shaft group of slat conveyer, and the sprocket shaft group is short service life.
Summary of the invention
The technical matters that the present invention will solve provide a kind of to electrical network impact little, the sprocket shaft group is impacted the mining down-hole of fluid motor-driven slat conveyer little, sprocket shaft group long service life.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of fluid motor-driven is mining down-hole slat conveyer; Comprise motor and slat conveyer sprocket shaft group; But the permanent power Hydraulic Pump, fuel tank and the constant displacement hydraulic motor that also comprise bidirectional variable; Motor links to each other with Hydraulic Pump, is connected through oil pipe respectively between fuel tank, Hydraulic Pump and the HM Hydraulic Motor, and hydraulic motor output shaft links to each other with slat conveyer sprocket shaft group.
Fluid motor-driven of the present invention is mining down-hole slat conveyer, the oil discharge outlet of wherein said Hydraulic Pump communicates with the oil inlet of HM Hydraulic Motor through first oil pipe, and the return opening of HM Hydraulic Motor communicates with the return opening of Hydraulic Pump through second oil pipe; First oil pipe is provided with first control cock, and second oil pipe is provided with second control cock, and the drain tap of Hydraulic Pump communicates with fuel tank through overflow oil tube; The repairing pipe links to each other with first filter; First filter communicates with fuel tank, and slippage pump is provided with the 3rd control cock, and the drain tap of HM Hydraulic Motor is connected with second filter through second overflow oil tube; Second filter communicates with fuel tank, and second filter is provided with the 4th control cock.
Fluid motor-driven of the present invention is mining down-hole slat conveyer; But adopt the permanent power Hydraulic Pump of bidirectional variable, the sprocket shaft group that constant displacement hydraulic motor is slat conveyer that power is provided; Through the hydraulic system transfers specified rate HM Hydraulic Motor of enclosed, hydraulic motor output shaft links to each other with slat conveyer sprocket shaft group.Fluid motor-driven of the present invention is mining down-hole slat conveyer adopts hydraulic power system, comes the output torque and the hand of rotation of regulator solution pressure motor through the modulated pressure pump; Thereby the speed governing of Quality Initiative axle set, start and stop and counter-rotating; Can be converted into the oil liquid pressure ability through electromechanics, the HM Hydraulic Motor volume is little, in light weight, and movement inertia is little; When frequent start-stop, big cranking torque, little when needing speed governing occasion and counter-rotating to the influence of sprocket shaft group.
Description of drawings
Fig. 1 is the structural representation of the hydraulic power system of the mining down-hole of fluid motor-driven of the present invention slat conveyer.
The specific embodiment
As shown in Figure 1; Fluid motor-driven of the present invention is mining down-hole slat conveyer comprise hydraulic power system and slat conveyer sprocket shaft group 6, but hydraulic power system comprises permanent power Hydraulic Pump 2, fuel tank 3, the constant displacement hydraulic motor 4 of motor 1 bidirectional variable; The output shaft of motor 1 links to each other with the input shaft of Hydraulic Pump 2 through spline; The oil discharge outlet 23 of Hydraulic Pump 2 communicates with the oil inlet 41 of HM Hydraulic Motor 4 through first oil pipe 24, and the return opening 42 of HM Hydraulic Motor 4 communicates with the return opening 25 of Hydraulic Pump 2 through second oil pipe 43, and first oil pipe 24 is provided with first control cock 241; Second oil pipe 43 is provided with second control cock 431; The drain tap of Hydraulic Pump 2 communicates with fuel tank 3 through overflow oil tube 22, and the repairing mouth of Hydraulic Pump 2 links to each other with first filter 7 through repairing pipe 5, and first filter 7 communicates with fuel tank 3; First filter 7 is provided with the 3rd control cock 71; The drain tap of HM Hydraulic Motor 4 is connected with second filter 9 through overflow oil tube 8, and second filter 9 communicates with fuel tank 3, and second filter 9 is provided with the 4th control cock 91.The output shaft of HM Hydraulic Motor 4 links to each other with slat conveyer sprocket shaft group 6 through spline.Motor 1 adopts the 220V motor, has substituted the high-voltage motor in the traditional power system, when further having reduced start and stop to the impact of electrical network.
Fluid motor-driven of the present invention is mining down-hole slat conveyer, employing hydraulic power system, 2 work of motor 1 drive Hydraulic Pump; Motor 1 sends kinetic energy to hydraulic pressure potential energy that Hydraulic Pump converts Hydraulic Pump 2 to; Hydraulic Pump 2 is gone into HM Hydraulic Motor 4 with oil pump, and hydraulic pressure potential energy is passed to HM Hydraulic Motor 4, and HM Hydraulic Motor 4 becomes mechanical torque with hydraulic potential energy converting and energy; Output torque is that slat conveyer sprocket shaft group 6 provides power, drives slat conveyer work.Come the output torque and the hand of rotation of regulator solution pressure motor 4 through modulated pressure pump 2, thereby control 6 speed governing of slat conveyer sprocket shaft group, start and stop and counter-rotating.
During hydraulic power system work; First and second control cock 241,431 is opened; When HM Hydraulic Motor 4 is just changeing; The oil inlet 41 that the oil discharge outlet 23 of oil self-hydraulic pump 2 is expelled to HM Hydraulic Motor 4 gets into, and oil pressure promotion HM Hydraulic Motor 4 is just changeing drive slat conveyer sprocket shaft group 6 and just changeing, and flows out to periodical dutys in the Hydraulic Pump 2 from return opening 42 then.During HM Hydraulic Motor 4 counter-rotatings, the return opening 42 that the return opening 25 of oily self-hydraulic pump 2 is expelled to HM Hydraulic Motor 4 gets into, and oil pressure promotes HM Hydraulic Motor 4 counter-rotatings and drives 6 counter-rotatings of slat conveyer sprocket shaft group, flows out to periodical duty in the Hydraulic Pump 2 from oil inlet 41 then.
When especially Hydraulic Pump 2 is discharged in speed change or start-stop process in the working process shortage of oil; Open the 3rd control cock 71; Through first filter 7 extraction of the oil in the fuel tank 3 is delivered in the Hydraulic Pump 2 through repairing pipe 5, first filter 7 filters through the oil that the filtering net on it will suck in taking out oil-absorbing process simultaneously, when the oil in the HM Hydraulic Motor 4 too much need release; Open the 4th control cock 91; Through second filter 9 surplus oil in the HM Hydraulic Motor 4 is extracted out, through overflow oil tube 8 oil is transported in the fuel tank 3, second filter 9 filters through the oil that the filtering net on it will suck in taking out oil-absorbing process simultaneously.
Above-described embodiment describes preferred implementation of the present invention; Be not that scope of the present invention is limited; Design under the prerequisite of spirit not breaking away from the present invention; Various distortion and improvement that those of ordinary skills make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
