Abstract
The utility model discloses a diesel hydraulic drive device for a flatcar. The diesel hydraulic drive device comprises a speed reducer connected with a drive wheel set, wherein an output shaft and an input shaft of the speed reducer are connected with the drive wheel set and a hydraulic motor in a transmission manner through a large shaft coupler and a high-speed shaft coupler respectively; an oil supply pipeline of the hydraulic motor is connected with a hydraulic variable plunger pump; the hydraulic variable plunger pump works in a manner that a diesel engine is driven through a belt. Each flatcar is equipped with a set of independent diesel hydraulic drive device, so that the drive problems of long-distance transport flatcars are solved. Compared with a cable drum power supply mode and a low-voltage rail power supply mode, the diesel hydraulic drive device has the advantages of reliability in use and lower investment.
Description
Technical field
The utility model belongs to handling machinery field, a kind of diesel engine hydraulic drive unit for flatcar of specific design.
Background technique
Flatcar is between industrial factories and miness workshop, to cross the capital equipment across material transportation, is generally to move on ground rail.The conventional motor of drive form of flatcar drives adhesion wheel group by speed reducer, and power supply mode has cable drum or low voltage rail power supply.For short distance transportation, adopt cable drum power supply better, for long-distance transportation, as adopted cable drum power supply, cable is oversize, batches difficulty large, and long cable drags easily to be affected on the ground other work and easily damage by pressure.The long another way apart from flatcar power supply is low voltage rail power supply, by electric installation, 36v low tension is received on haulage vehicle, by mobile transformer, 36v electricity being converted to 380V electricity again comes power supply machine to use, this mode is due to a plurality of transformers of needs, track laying is complicated, make whole equipment and the investment of track ground larger, sometimes also can be because of the bad trouble of shutdown that causes of conduction.The utility model proposes a kind of new flatcar drive unit for long-distance transportation.
Summary of the invention
In order to solve the driving problems for the flatcar of long-distance transportation, reach that investment is relatively little, service-strong object, the utility model proposes a kind of flatcar diesel engine hydraulic drive unit.
The utility model patent solves the technological scheme that its technical problem adopts:
A kind of flatcar diesel engine hydraulic drive unit, include the speed reducer being connected with adhesion wheel group, the output shaft of described speed reducer, input shaft are connected with adhesion wheel group, hydraulic motor transmission by large coupling, high-speed coupling respectively, the oil feed line of oil hydraulic motor is connected with hydraulic variable flow plunger pump, and hydraulic variable flow plunger pump is worked by belt transmissioning mode by diesel engine.
In described hydraulic variable flow plunger pump and the oil feed line of oil hydraulic motor, selector valve is installed.
Diesel engine is as power source, diesel engine is connected to drive hydraulic variable flow plunger pump to turn round with hydraulic variable flow plunger pump by belt transmission, hydraulic variable flow plunger pump is connected with the low speed high torque hydraulic motor with built-in break by hydraulic control system, by hydraulic control system, controlling oil hydraulic motor rotates, oil hydraulic motor is connected with speed reducer through high-speed coupling again, speed reducer is sleeved on wheel group driving shaft, by large coupling, be connected with another wheel group, thereby realize the driving of two adhesion wheels.
By Joystick, control solenoid-operated proportional selector valve in hydraulic control system, realize limitless speed governing and commutation to drive motor, motor carries bidirectional balanced braking device and coordinates control valve to use, and is implemented to spacingly without impacting, to stop or arbitrary position stops without impact.
The invention has the beneficial effects as follows, on each flatcar, configure a set of independently diesel engine hydraulic drive unit, solved the flatcar driving problems of long-distance transportation, compared with low voltage rail power supply mode and have advantages of that respectively use is reliable, investment is relatively little with cable drum power supply.
Accompanying drawing explanation
Fig. 1 is flatcar diesel engine hydraulic drive unit schematic diagram of the present utility model.
Embodiment
The diesel engine hydraulic of flatcar shown in Fig. 1 drive unit, for 120-ton load capacity, flatcar motion speed 25m/min, range ability 120m, by diesel engine 1, drivign belt 2, hydraulic variable flow plunger pump 3, selector valve 4, oil hydraulic motor 5, high-speed coupling 6, speed reducer 7, large coupling 8, adhesion wheel group, adhesion wheel group includes two adhesion wheels 9,10 and forms.
In Fig. 1, adhesion wheel 9,10 is two groups of adhesion wheel groups on a flatcar, adopts centralized driving, by 4105ZD diesel engine 1, provides power, and diesel engine output power is 40KW, and output speed is 1500rpm.Diesel engine 1 drives hydraulic variable flow plunger pump 3 by the belt transmission 2 of reduction speed ratio 1:2.By selector valve 4, controlled the running of JMDG1-80 oil hydraulic motor 5, output speed is 15 ~ 1000rpm, and oil hydraulic motor 5 is connected with the input shaft of speed reducer 7 by high-speed coupling 6.Speed reducer 7 models are GKABSZ107, are sleeved on wheel group driving shaft, and reduction speed ratio is 1:35.With large coupling 8, connect another adhesion wheel 9, thereby realize the driving of two adhesion wheels, vehicle wheel rotational speed is 12.24rpm, and wheel diameter is Φ 630, meets usage requirement.
By Joystick and programmable controller PLC, control solenoid-operated proportional selector valve in hydraulic control system, limitless speed governing and commutation to drive motor have been realized, motor carries bidirectional balanced braking device and coordinates control valve to use, and has realized reliably spacingly without impact, stopping or arbitrary position stops without impact.
