[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below.

[0025] Example 1: The tractor hydraulic system is an indispensable part of tractor operation. It not only affects the working efficiency of the tractor, but is also directly related to the safety and reliability of the tractor.

[0026] In order to accurately and quickly detect the output power and maximum oil pressure of the tractor hydraulic system, Figure 1 As shown, the utility model proposes an integrated multi-channel adjustment hydraulic detection device, which has a compact structure, is easy to operate, and is highly portable, and can meet the on-site detection needs of tractor hydraulic systems.

[0027] like Figure 1As shown, the multi-way hydraulic pressure detection device comprises a cabinet 1, an oil pipeline, and a detection device. The cabinet 1 is divided into two parts, the upper part housing the controller and power supply, and the lower part housing the detection device. An oil pipeline connects the tractor hydraulic system and the detection device, with the outer ends of the pipeline being equipped with an oil inlet connector 6 and an oil outlet connector 7.

[0028] like Figure 2 and Figure 3 As shown, the detection device installed in the cabinet 1 includes a multi-channel valve block 9, a coarse adjustment throttle valve 11, a fine adjustment throttle valve 12, a flow meter 13 and an oil pressure control overflow valve 14.

[0029] The controller includes a PLC controller 15 and a measurement and control host 16, which are used for data acquisition, processing and control.

[0030] The sensors include an oil pressure sensor 8, an oil pressure and temperature sensor 10 and a flow meter 13, which are used to detect various parameters of the hydraulic system.

[0031] The display 3 and the operation buttons 4 are installed on the upper part of the cabinet 1 and are used to display the detection data and information.

[0032] like Figure 1 As shown, a cabinet door 2 is provided at the rear side of the cabinet body 1 to facilitate maintenance of the detection device; universal wheels are installed at the bottom of the cabinet body 1 and handles 19 are provided on the side to facilitate movement.

[0033] like Figure 2 As shown, a pipe rack 5 is also provided in the cabinet 1, and the oil pipeline is hung on the pipe rack 5 to prevent the oil pipeline from being twisted or damaged. Figure 4 As shown, the pipe rack 5 includes a cross brace 17 fixed in the cabinet 1, and both ends of the cross brace are fixed to the inner wall of the cabinet. A clamp 18 is provided on the cross brace. The clamp 18 is an elastic clamp composed of two semicircular elastic metal sheets. The semicircular elastic metal sheets are welded to the cross brace through one end, and a gap is reserved between the other ends of the two semicircular elastic metal sheets to form an opening. The oil pipeline can be clamped on the clamp through the opening, or removed from the clamp through the opening.

[0034] Specific working process: Connect the detection device to the tractor's hydraulic system via the oil inlet male connector 6 and the oil outlet male connector 7. The oil pressure sensor 8, oil pressure and temperature sensor 10, and flowmeter 13 collect real-time pressure, temperature, and flow data from the hydraulic system and transmit the data to the PLC controller 15. The PLC controller 15 processes the collected data and calculates the power and other relevant parameters of the hydraulic system. According to the preset control strategy, the PLC controller 15 controls the on and off of the multi-channel valve block 9 and the switching of the coarse and fine adjustment throttle valve 12 to adjust the flow and pressure of the hydraulic system. The measurement and control host 16 transmits the processed data to the display 3, where the user can view the test results and related information. If abnormal data is detected, the PLC controller 15 will trigger an alarm and record the fault information to help users identify and solve problems in a timely manner.

[0035] When in use, move the detection device near the tractor, ensure that there is enough space for connection, open the cabinet door 2, check whether the detection device is intact, confirm that all components are working properly, connect the power supply, and start the controller and the measurement and control host 16.

[0036] Connect the oil inlet male connector 6 and the oil outlet male connector 7 to the corresponding interfaces of the tractor hydraulic system respectively, ensuring that the connections are firm to avoid oil leakage.

[0037] Select the corresponding detection mode on the operation interface, such as power detection, pressure detection, etc., enter the necessary parameters, such as tractor model, hydraulic system rated parameters, etc., start the device, and the PLC controller 15 begins to control the multi-channel valve block 9 and the throttle valve to adjust the flow and pressure of the hydraulic system. During the detection process, the oil pressure sensor 8, oil pressure temperature sensor 10 and flow meter 13 collect data in real time and transmit the data to the PLC controller 15.

[0038] The PLC controller 15 processes the collected data and calculates the power and other relevant parameters of the hydraulic system. The data results are displayed on the display 3, and the user can view the detection results in real time. If abnormal data is detected, the PLC controller 15 will trigger an alarm and record the fault information. The user can perform further inspection and maintenance based on the fault information.

[0039] The entire detection device described in the utility model is integrated in an electrical cabinet box. The bottom of the electrical cabinet box is provided with universal wheels, which is convenient for movement and is suitable for various venues. Through the display 3 and the operation buttons 4, the user can easily complete the detection operation without professional skills. The sensors are reasonably arranged and the data is collected accurately, which can provide reliable detection results. The PLC controller 15 and the measurement and control host 16 can realize real-time data collection and processing, which is convenient for fault diagnosis and performance analysis. The dual throttle valve setting and hydraulic protection measures ensure the safety and stability during the detection process.

[0040] The integrated multi-channel adjustment hydraulic detection device provided by the utility model can effectively improve the detection efficiency and accuracy of the tractor hydraulic system, and provide strong support for the maintenance and optimization of the tractor.

[0041] In actual inspection work, it is usually necessary to inspect multiple hydraulic systems at a time, and the frequent plugging and unplugging of the hydraulic systems seriously affects the efficiency of the relevant inspection work. Therefore, in order to improve the inspection efficiency, the multi-channel valve block used in the utility model is provided with three oil inlets, and the three oil inlets are connected to three oil inlet male heads. When in use, the three oil inlet male heads are directly connected to the three hydraulic systems, and the on-off switching of the relevant oil inlets is controlled by the multi-channel valve block to the hydraulic system that needs to be inspected. The multi-channel valve block can adopt a three-in-one-out structure, or a three-in-three-out structure. When the three-in-one-out multi-channel valve block is used, it is necessary to follow the hydraulic system to which the oil outlet male head is plugged, and then switch the corresponding oil inlet male head to connect; the three-in-three-out multi-channel valve block can directly connect three hydraulic systems in parallel, and when in use, the hydraulic system to be inspected can be switched by directly controlling the multi-channel valve block to switch on and off.

[0042] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
