Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic systems, in particular to a remote-controlled ultra-high pressure hydraulic pump station, which provides a hydraulic power source for railway rescue tools and improves the convenience of rescue operations. Background Art

[0002] The hydraulic pump stations of existing railway rescue tools are all operated manually, and the existing electrical control pump stations are all low-pressure products with a low maximum working pressure, which cannot meet the needs of railway rescue equipment. The existing ultra-high pressure hydraulic pump stations are more complicated to work with, have lower ease of use, and increase the probability of error. At the same time, the hydraulic pump stations of existing railway rescue tools often have shortcomings such as high return oil pressure, inability to unload in the middle position, and inability to adjust the pressure during implementation.

The power device drives the hydraulic pump to take the hydraulic oil in the oil tank into the load proportional multi-way valve, and outputs the hydraulic oil to the hydraulic motor to realize the hydraulic motor drive. The pressure relief or high and low pressure switching of the above hydraulic pump can be operated through the electric hydraulic pump or the control handle. The operator who controls the hydraulic pump needs to keep an eye on the pressure gauge of the hydraulic pump at any time, and remote control is not possible. The pressure adjustment of the device is relatively cumbersome, and the device has the disadvantages of high return oil pressure and inability to achieve neutral unloading.

The device manually operates the remote control unit to issue instructions, and the control module receives the instructions to control the operation of the motor. The motor drives the oil supply port of the plunger pump to discharge oil. The plunger pump supplies oil to two hydraulic cylinders at the same time through the diverter valve. The device can be remotely controlled. During the implementation process, the hydraulic pump station uses a speed regulating throttle valve to control the pressure in the oil circuit. The speed regulating throttle valve has a slow adjustment speed. There are disadvantages such as inability to unload in the middle position and slow pressure adjustment during the operation of the equipment.

The hydraulic oil tank 2, the control integrated block 5 and the electrical remote control system 6 are all fixed on the trolley body 1, and a universal wheel is provided under the trolley body 1. The ultra-high pressure pump group 3 is arranged in the hydraulic oil tank 2, and the ultra-high pressure pump group 3 is fixedly connected to the hydraulic oil tank 2. The driving device 4 is fixedly connected to one side of the top of the hydraulic oil tank 2. A coupling is provided at the front end of the driving device 4, and the driving device 4 is key-connected to the ultra-high pressure pump group 3 through the coupling. The control integrated block 5 is installed on the other side of the top of the hydraulic oil tank 2.

[0024] In some embodiments, the ultra-high pressure pump group 3 also includes: a plunger pump 201, a pressure regulating relief valve 202, a one-way valve 204 and a pressure relay 205. The four plunger pumps 201 and the pressure regulating relief valve 202, the two-position two-way solenoid ball valve 203 and the one-way valve 204 form an oil circuit one. The tail end of the circuit one is connected to the pressure relay 205. One end of the two-position two-way solenoid ball valve 203 is connected to the hydraulic oil tank through a pipeline. When the pressure and flow in the oil circuit are too large, the valve core of the two-position two-way solenoid ball valve 203 opens to allow the liquid in the oil circuit to flow back to the hydraulic oil tank. When the pressure and flow in the oil circuit return to normal pressure and flow, the valve core of the two-position two-way solenoid ball valve 203 closes, thereby realizing the mid-position unloading of the hydraulic pipeline. The pressure regulating relief valve 202 controls the return oil pressure in the oil circuit to protect the hydraulic system and the machine from equipment damage caused by overload.

[0025] In some embodiments, the utility model is provided with eight plunger pumps 201 to provide power sources for two groups of hydraulic cylinders, and a pressure regulating relief valve 202 is used to adjust the pressure of the system. When the system pressure exceeds the set value, the pressure regulating relief valve 202 opens to return the excess fluid to the oil tank to keep the system pressure stable. A pressure relay 205 is used to monitor the pressure changes of the system. When the pressure reaches the set value, the pressure relay 205 sends a control signal to control the pressure regulating relief valve to release the pressure. When the pressure relay 205 detects that the pressure value is continuously greater than the preset value, an alarm is issued.

[0026] In some embodiments, the control integrated block 5 includes: an integrated block body 501, a pressure flow regulating valve 502, a direction control valve 503, and a return pressure control valve 504. The integrated block body 501 is connected to the hydraulic oil tank 2 through a conduit. The pressure flow regulating valve 502 is arranged above the integrated block body 501 and is flange-connected to the integrated block body 501 for adjusting the output oil circuit pressure. The return pressure control valve 504 is flange-fixed above the integrated block body 501 for adjusting the return oil circuit pressure. The direction control valve 503 is arranged above the return pressure control valve 504 and the direction control valve 503 is threadedly connected to the return pressure control valve 504 for adjusting the output direction of the oil circuit. The control integrated block 5 is provided with multiple sets of actuators according to usage.

[0027] In some embodiments, the electrical remote control system 6 includes: a remote control, a receiver, a data collector, a relay control module, a power supply module, a control start button 601 and a control reset button 602. The power supply module supplies power to the receiver, the data collector, the relay control module control integrated block 5 and the drive device 4. The data collector monitors various data in the ultra-high pressure hydraulic pump station in real time. The data collector compares the collected information with the preset value. When the collected information exceeds the preset threshold, the data collector sends an alarm signal to the remote control through the receiver. The relay control module receives the data information transmitted by the receiver and manages the control integrated block 5. The electrical remote control system 6 is manually started by the control start button 601, and the control reset button 602 resets the electrical remote control system 6.

[0028] In some embodiments, the remote controller transmits signals to the receiver via 433MHZ long wave, the receiver and the device are controlled by CAN communication, and the data collector and the receiver are data collected by 485 communication.

[0029] Embodiment 1: In a specific implementation mode provided by the present utility model, as Figure 1-Figure 6 As shown: After the equipment is transported to the designated location, adjust the angle of the trolley to meet the needs of pipeline connection, bolt and fix the device that needs to be pumped to the remote-controlled ultra-high pressure hydraulic pump station, press the start button 8 to start the pump station, the power supply module supplies power to the equipment, and the data collector collects various information of the equipment. When the data information is normal, the equipment operation indicator 7 shows green.

[0030] A control start knob and a control reset knob are provided on the side of the electrical remote control system 6 of the device. The control start knob is rotated to start the electrical remote control system 6, and the data of the device is set through the remote control. After the setting is completed, the drive device 4 and the plunger pump 201 are started, and hydraulic oil is extracted from the hydraulic oil tank 2 to supply oil to the oil circuit system. In the ultra-high pressure pump group 3 of the device, four plunger pumps 201 and the pressure regulating relief valve 202, the two-position two-way electromagnetic ball valve 203 and the one-way valve 204 are bolted together through pipelines to form an oil circuit. The device can provide multiple groups of oil circuits, and the number of oil circuits to be opened can be selected as needed. When two groups of oil circuits are opened, the oil circuits are adjusted by the relief valve to form two high-pressure oil circuits, which provide power sources for the two groups of hydraulic cylinders.

[0031] The device can remotely adjust the oil pressure parameters through a remote controller. The receiver receives the information transmitted by the remote controller and sends the received information to the relay control module. The relay control module sends adjustment information to the control integrated block 5 to realize remote control of the ultra-high pressure hydraulic pump station.

[0032] When the pressure relay 205 detects that the pressure exceeds the preset threshold or the data collected by the data collector does not meet the daily settings, the device sends an alarm reminder to the remote control through the receiver, and the equipment operation indicator light 7 of the device is displayed as a red light.

[0033] When the device needs to be stopped urgently due to special circumstances, the emergency stop button 9 is pressed, the drive device 4 and the plunger pump 201 stop outputting oil, and the pressure is slowly released through the pressure regulating relief valve 202.
