Description

Technical Field

[0001] The utility model relates to the field of locomotive repair and maintenance, in particular to an intelligent portable electromagnetic mechanism or electromagnetic valve control box. Technical Background

[0002] There are two major categories of actuators in the control system of electric locomotives. The first category, electromagnetic systems, usually include electrical components such as contactors and relays, which are usually installed in cabinets and control boxes. The core of each component is the electromagnetic coil, which requires a DC power supply of corresponding voltage during its operation. Static inspection of electromagnetic mechanisms is relatively hidden and difficult to detect, and can only be discovered through dynamic inspection when power is on. During the action performance test, the power supply is required to have the function of regular intermittent output in conjunction with the electromagnetic mechanism.

[0003] In addition, electric locomotive air control systems include a large number of air source control components, such as solenoid valves and electro-pneumatic valves, typically installed in cabinets and valve plates. In the air circuit control of high-voltage equipment, such as the HX high-voltage disconnector, the solenoid valve plays a decisive role in controlling the air cylinder's working air circuit. Reliable switching of the two-position solenoid valve requires a DC power supply with the corresponding voltage. For example, the HXD1D high-isolation, two-position, five-way solenoid valve has two solenoid coils, requiring a power supply with two outputs, adjustable voltage, intermittent switching, and adjustable operating frequency to control the reciprocating motion of the air cylinder and ensure the blades close and open according to process specifications. This allows for testing and observing the operating performance of the high-voltage disconnector.

[0004] In recent years, as locomotive maintenance operations have become more flexible and diverse, the innovation of maintenance equipment is also imminent. The existing power supply equipment for maintenance electromagnetic mechanisms or solenoid valves is no longer suitable for efficient and high-quality production operations. In a complex and changeable operating environment, it cannot meet the maintenance team's various workstations' efficient maintenance and inspection operations of each electromagnetic mechanism or solenoid valve, as well as the performance test requirements of various accessories. The lack of equipment has made it impossible to strictly implement maintenance work, slowed down the progress of locomotive maintenance, and made it difficult to ensure maintenance quality. Utility Model Content

[0005] The purpose of the utility model is to provide an intelligent portable electromagnetic mechanism or electromagnetic valve control box to solve the problems of backward power supply equipment for electromagnetic mechanism or electromagnetic valve maintenance in existing locomotive maintenance work, inability to strictly implement maintenance, and low maintenance efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] An intelligent portable electromagnetic mechanism or electromagnetic valve control box is connected to a test element to provide corresponding power for the maintenance of the test element. The control box includes a box body and an operation display panel. The circuit inside the box consists of a main circuit, a control circuit and a display circuit. The main circuit includes a circuit breaker, a power module, a contactor, an output socket and a voltage regulating knob. The output socket is used to connect the test element, and the voltage regulating knob is used to adjust the output power supply voltage; the control circuit includes a processor, a start button and a stop button. The processor controls the contactor to automatically close and open at a fixed time to output intermittent power; the display circuit includes a power light and a digital voltmeter. The digital voltmeter dynamically monitors the load voltage of the test element in real time.

[0008] Furthermore, the power module includes an AC220V-DC24V power module and an AC220V-DC110V power module. The circuit breaker simultaneously controls the on and off of the AC220V-DC24V power module and the AC220V-DC110V power module. The AC220V-DC24V power module is connected to the processor, the AC220V-DC110V power module is connected to the contactor input end, and the contactor output end is connected to the output socket. There are two groups of output sockets.

[0009] After the control box receives AC 220V power input, one route is converted into DC 24V by the AC220V-DC24V power module for use by the processor, and the other route is converted into DC 110V by the AC220V-DC110V power module for output through the contactor. The circuit breaker controls two power modules at the same time. The solenoid valve action test requires two sets of output power supplies, so two sets of output sockets are set.

[0010] Furthermore, the output socket and the test element are connected by a connecting cable, the output socket adopts a banana jack, and both ends of the connecting cable adopt banana plugs.

[0011] The output socket and both ends of the connecting cable adopt banana jacks and banana plugs, which make the connection contact area larger, the connection is neater and safer, and it is convenient and fast to plug in and out when needed.

[0012] Furthermore, the processor adopts Siemens S7-200 series CPU224 programmable logic controller.

[0013] Siemens S7-200 series CPU224 programmable logic controller as a processor has powerful functions and superior performance. It can intelligently control the automatic closing and breaking of contactors in real time and output intermittent power to electromagnetic mechanisms or solenoid valves.

[0014] Furthermore, one side surface of the box serves as an operation display panel, and the circuit breaker, voltage regulating knob, start button, stop button, power light, and output socket are all fixed on the operation display panel.

[0015] The simple operation display panel makes operation simpler and safer. When the circuit breaker is closed, power supply starts and the power light comes on. The voltage adjustment knob can adjust the output voltage and can be manually adjusted as needed. The digital voltmeter can monitor and display the load voltage of the test component in real time. The start and stop buttons are used to start or stop the experimental work of the control box.

[0016] Furthermore, a heat dissipation fan is provided in the box body, and heat dissipation holes are provided on the side walls of the box body.

[0017] The design of the cooling fan and heat dissipation holes can effectively dissipate heat for the processor and power module in the box, keeping them in good operating condition.

[0018] Furthermore, a straight handle is provided on the outside of the box.

[0019] The straight handle makes it more convenient to carry and can be used flexibly in various occasions.

[0020] Furthermore, a CPU communication port is provided on the box.

[0021] The CPU communication port is set to facilitate future control program upgrades to adapt to different production tasks.

[0022] Furthermore, the box body is made of thin iron sheet.

[0023] The control box is made of thin iron sheet without affecting the working performance. It is light to carry and can be flexibly operated in many occasions. At the same time, it provides enough space for the layout of internal electrical components.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The utility model can realize adjustable output voltage and timed intelligent output of intermittent power supply through the control circuit. At the same time, the electronic voltmeter on the operation display panel can dynamically monitor and display the load voltage of the test component in real time, thereby realizing the output intermittent on-off function of the maintenance test electromagnetic mechanism and the working state conversion function of the test electromagnetic valve, providing corresponding power supply for the maintenance test of the electromagnetic mechanism or the electromagnetic valve, greatly improving the maintenance quality and efficiency, and saving labor costs; at the same time, a straight handle is provided on the box body, and the control box body is made of thin iron sheet, which is easy to carry and can be used for flexible operation in multiple occasions; a cooling fan is also provided in the box body, and cooling holes are provided on the box body, which can timely dissipate heat to the processor and the power module to keep them in good working condition and realize continuous long-term operation.
