Description

Technical Field

[0001] This utility model relates to the technical field of train brake testing devices, and specifically to a train brake testing device. Background Technology

[0002] The existing train brake testing device structure is described in Chinese Utility Model Patent Publication No. CN 220625780U, entitled "A Train Brake Testing Actuator". In this patent, the corresponding components are connected by a bent pipe. The bent pipe needs to be specially customized and has high processing precision requirements. This not only increases the precision requirements, cost and production cycle of component processing and manufacturing, but also imposes stringent requirements on assembly precision. During the assembly process, the coaxiality and sealing of each pipeline need to be calibrated multiple times. It is easy to cause problems such as air leakage and inaccurate test data due to operational errors. At the same time, the complex connection structure also increases the difficulty and time cost of later maintenance, which is not conducive to the large-scale production and efficient field application of the device.

[0003] In addition, the single-layer cabinet structure adopted by this patent disperses the air circuit and circuit inside the cabinet. During assembly, the installation position is too compact, the internal component positions are not reasonable, troubleshooting is troublesome, and maintenance is time-consuming. At the same time, the vibration and air pressure fluctuation generated by the operation of the air circuit components can easily affect the circuit module through the shared installation space. Utility Model Content

[0004] The purpose of this invention is to provide a train brake testing device to solve at least one of the aforementioned problems in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A train brake testing device includes a cabinet, a circuit assembly, and a pneumatic circuit assembly. The cabinet is provided with a shelf that divides the cabinet into an upper space and a lower space. The circuit assembly is located in the upper space and the pneumatic circuit assembly is located in the lower space. The cabinet includes an upper door panel corresponding to the upper space and a lower door panel corresponding to the lower space. The air circuit assembly includes an air inlet connector, a tee fitting, a first quick-connect connector, a clamp, a second quick-connect connector, a valve group, an air outlet pipe, and an air outlet connector, which are coaxially connected in sequence along the width direction of the lower space. The valve group is fixed to the bottom plate of the lower space by a support base, and the air inlet connector and the air outlet connector are fixed to the left and right side plates of the cabinet by flanges, respectively.

[0006] This technical solution divides the cabinet into upper and lower spaces using shelves. The circuit components are located in the upper space, and the pneumatic components in the lower space. This separation of the circuit and pneumatic components facilitates troubleshooting and improves maintenance efficiency. Furthermore, the vibrations and pressure fluctuations generated by the pneumatic components do not affect the circuit components. The cabinet includes an upper door panel corresponding to the upper space and a lower door panel corresponding to the lower space, allowing for easy access to either space. Because the pneumatic assembly includes an air inlet connector, a tee fitting, a first quick-connect connector, a clamp, a second quick-connect connector, a valve group, an air outlet pipe, and an air outlet connector, all coaxially connected along the width of the lower space, the valve group is fixed to the bottom plate of the lower space via a support base. The air inlet and air outlet connectors are respectively fixed to the left and right side panels of the cabinet via flanges. All components in the pneumatic assembly are coaxially arranged and coaxially plugged together, eliminating the need for bends and ensuring convenient installation. The entire assembly process does not require specialized calibration tools, and ordinary assembly personnel can operate it after simple training, reducing the difficulty of assembly. Furthermore, the pneumatic leakage rate after assembly is very low, ensuring no leakage in the pneumatic circuit, meeting the pneumatic performance requirements of the train tester, and improving the reliability of the equipment.

[0007] Furthermore, the upper door panel includes an outer door panel and an inner door panel. The outer door panel is provided with a transparent plate, and the inner door panel is provided with a pressure gauge, a push-button switch, and an indicator light.

[0008] The existing train brake testing device cabinet lacks a visual operation panel and transparent human-machine interaction. This technical solution can meet the human-machine interaction function by setting pressure gauges, push-button switches and indicator lights on the inner panel, and the outer door panel is equipped with a transparent panel to facilitate observation of the internal pressure gauges and indicator lights.

[0009] Furthermore, the upper door panel includes an outer door panel and an embedded industrial control computer. The outer door panel has a transparent panel, and the embedded industrial control computer is located on the inner side of the outer door panel. This can meet different on-site needs, allowing for both remote control from the control room and direct use of the industrial control computer for air testing.

[0010] Furthermore, the valve assembly includes a filter, a proportional valve, a relay valve, a pneumatic shut-off valve, a solenoid valve, and an outlet air pressure sensor.

[0011] Furthermore, the top of the cabinet is provided with a herringbone-shaped top plate.

[0012] Furthermore, the cabinet body is made of stainless steel or cold-rolled steel sheet. The thin sheets are formed by sheet metal structure design, processing, and welding.

[0013] Furthermore, a first antenna and a second antenna are provided on the outside of the cabinet. The external placement of the antennas increases their stability and reliability. The first and second antennas are routed separately to reduce interference between signals of different frequency bands and power levels.

[0014] Furthermore, to facilitate on-site installation, a mounting plate is vertically installed in the upper space, and the circuit components are mounted on the mounting plate.

[0015] The beneficial effects of this utility model are as follows: In this technical solution, because the shelves divide the cabinet into upper and lower spaces, the circuit components are located in the upper space, and the pneumatic components are located in the lower space. This layered separation of the circuit and pneumatic components makes troubleshooting easier and improves maintenance efficiency. Furthermore, the vibrations and air pressure fluctuations generated by the pneumatic components will not affect the circuit components. The cabinet includes an upper door panel corresponding to the upper space and a lower door panel corresponding to the lower space, facilitating the opening of either the upper or lower space. Because the pneumatic assembly includes an air inlet connector, a tee fitting, a first quick-connect connector, a clamp, a second quick-connect connector, a valve group, an air outlet pipe, and an air outlet connector, all coaxially connected along the width of the lower space, the valve group is fixed to the bottom plate of the lower space via a support base. The air inlet and air outlet connectors are respectively fixed to the left and right side panels of the cabinet via flanges. All components in the pneumatic assembly are coaxially arranged and coaxially plugged together, eliminating the need for bends and ensuring convenient installation. The entire assembly process does not require specialized calibration tools, and ordinary assembly personnel can operate it after simple training, reducing the difficulty of assembly. Furthermore, the pneumatic leakage rate after assembly is very low, ensuring no leakage in the pneumatic circuit, meeting the pneumatic performance requirements of the train tester, and improving the reliability of the equipment.

[0020] In this technical solution, the shelf 4 divides the cabinet 1 into an upper space 5 and a lower space 6. The circuit assembly 2 is located in the upper space 5, and the pneumatic assembly is located in the lower space 6. By separating the circuit assembly 2 and the pneumatic assembly into layers, troubleshooting and maintenance are more convenient and efficiency is improved in case of a fault.

The cabinet 1 includes an upper door panel corresponding to the upper space 5 and a lower door panel 7 corresponding to the lower space 6, facilitating the opening of either the upper space 5 or the lower space 6. Because the pneumatic assembly includes an air inlet connector 8, a tee fitting 9, a first quick-connect connector 10, a clamp 11, a second quick-connect connector 12, a valve group 13, an air outlet pipe 14, and an air outlet connector 15, all coaxially connected along the width of the lower space 6, with the valve group 13 fixed to the bottom plate of the lower space 6 via a support base 22, and the air inlet connector 8 and air outlet connector 15 fixed to the left and right side plates of the cabinet 1 respectively via flanges, the components in the pneumatic assembly are coaxially arranged and coaxially plugged together, eliminating the need for bends in the pipes and ensuring convenient installation.

[0036] In summary, the advantages of this technical solution are as follows: 1.

Simplified assembly: Through quick-connect and quick-plug docking and clamp 11 fixation, the original assembly process that required multiple calibrations is simplified to two steps of "docking-fixing", reducing the precision operation requirements of assembly personnel.

[0037] 3. Improved assembly efficiency: Modular design allows for independent pre-assembly of circuits and pneumatic circuits, requiring only cross-layer interfaces to be connected on-site, thus shortening the assembly cycle.

[0038] 4. Improved reliability: The straight-line connection of the pipeline improves the sealing stability of standard parts, effectively reduces the probability of air leakage, and ensures the accuracy of train test data; at the same time, the air-electric layer design reduces the interference of air vibration and air pressure fluctuation on circuit signals, thus improving the stability of test data.

[0039] 5. Easy Maintenance: The simplified piping structure and clear zoning layout allow for quick location of faulty pipes during later maintenance, reducing maintenance time by 40% and simplifying on-site maintenance. In case of a fault, the faulty layer and module can be quickly identified; for example, in the case of a circuit fault, only the upper circuit cavity needs to be repaired, reducing repair time.

[0040] 6. Enhance human-computer interaction: A visual operation panel is added, which integrates a pressure gauge 19 and operation button indicator lights 21. It can display key information such as charging and discharging pressure values ​​and operating status in real time; intuitively present test data and equipment operating conditions, reduce the difficulty of operation, avoid operational errors caused by information opacity, and improve the convenience of equipment operation and safety of use.

[0041] 7. Reasonable wiring layout prevents safety accidents, reduces interference between antennas, and improves equipment stability.
