Abstract
The utility model relates to a hydraulic pump station device for providing power sources for a controllable vehicle parking device of a railway. The utility model mainly comprises a tank body of an oil tank, and a cover body which is arranged on the tank body, wherein a motor which is connected with a gear pump arranged in the tank body of the oil tank through a coupling is arranged in the cover body; the other ends of an oil suction pipe and an oil discharge pipe connected with the gear pump are respectively connected with an oil filter and an overflow valve; the motor is a vertical motor; the oil discharge pipe which is connected with the gear pump is respectively connected with two electromagnetic reversing valves through two one-way valves, and oil outlets of the two electromagnetic reversing valves are respectively connected with two oil supply pipes. The utility model can control two groups of controllable vehicle parking devices, and has the characteristics of simple structure, small ground occupation, and convenient installation, use and maintenance.
Description
The utility model relates to a kind of hydraulic power unit device that propulsion source is provided for the railway controlled stopping device.
At present, the hydraulic pressure controlled stopping device that rail yard uses, the hydraulic power unit device that it is required mostly adopts horizontal machine, and not only floor area is big, and complex structure, particularly this device only can be controlled one group of (or one) controlled stopping device, if number of, lines is many, needs to adopt with the corresponding hydraulic power unit device of controlled stopping device quantity and implements control, equal inconvenience is installed, uses and keeped in repair to the energy resource consumption height.
In view of the foregoing, the purpose of this utility model provides the hydraulic power unit device of little and two groups of (or the two) controlled stopping devices of may command of a kind of floor area, makes it to be convenient to install, use and keep in repair, and reduces and installs and operating costs.
The purpose of this utility model is achieved in that it mainly comprises fuel tank casing and the cover body that places on this casing, be provided with motor in the cover body, this motor links to each other with gear type pump in placing the fuel tank casing by coupler, connect the oil suction pipe of this gear type pump and the other end of oil outlet pipe and be connected with oil filter and by pass valve respectively, it is characterized in that: motor is a vertical machine, the oil outlet pipe of connection gear pump links to each other with two solenoid directional control valves through two check valves respectively, and the oil outlet of two solenoid directional control valves connects two fuel feed pipes respectively.Gear type pump is by driven by motor work, and the hydraulic oil in the fuel tank sucks through oil filter, and the oil pressure in the oil circuit constantly raises.When oil pressure was higher than system's settling pressure, hydraulic oil flowed back in the fuel tank through the by pass valve drain charge, and when when work in two solenoid directional control valves, its bonded assembly check valve is just opened, and promptly hydraulic oil is through this check valve, solenoid directional control valve oil cylinder fuel feeding to controlled stopping device.Two solenoid directional control valves can not disturb mutually respectively to the oil cylinder fuel feeding of two controlled stopping devices.
In order to simplify complicated oil pipe line, two check valves, two solenoid directional control valves all link to each other by a multi-path oil pipe integrated package with two fuel feed pipes.
The utility model has the advantages that: floor area is little, and is simple in structure, particularly utilizes two groups of controlled stopping devices of this device may command, makes it to reduce greatly installation, operating costs, gives to install and keep in repair also to bring great convenience.
Below in conjunction with accompanying drawing the utility model is explained.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model hydraulic schematic diagram.
Fig. 3 is that the utility model is controlled two stopping device scheme drawings.
By accompanying drawing as can be known, this device c comprises fuel tank casing that is made of fuel tank 13 and fuel tank upper cover plate 14 and the cover body that is made of outer cover 18 and outer cover loam cake 1, and vertical machine 2 places in the cover body, links to each other with gear type pump 9 by coupler 7.The oil suction pipe 10 of gear type pump is connected with oil filter 11, the oil outlet pipe 20 of gear type pump is connected with by pass valve 16, compression indicator 19 and two check valves 17,17 ' (before and after among Fig. 1 each one, only can see one of fwd), two check valves 17 by multi-path oil pipe integrated package 5 respectively with two solenoid directional control valves 3,3 ' link to each other, the oil outlet of two solenoid directional control valves through integrated package 5 respectively with two fuel feed pipes 4,4 ' link to each other.Control two controlled stopping device a, b (see figure 3) by two fuel feed pipes 4,4 ' respectively.Oil level gauge 8 can be measured the hydraulic oil capacity in the fuel tank, and the air filter 12 of band filler port can refuel and play the filtered air effect.The compression indicator 19 of connection gear oil pump outlet line can be measured the system pressure value.Sequence number 15 is the by pass valve base plate among Fig. 1, and sequence number 6 is the pump disjunctor.
Claims (2)
