Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic valves, in particular to a hydraulic valve test bench which is easy to maintain. Background Art

[0002] A hydraulic valve is a device used to control the flow of fluid in a hydraulic system. Its primary function is to regulate the direction, pressure, and flow rate of the fluid. Hydraulic valves can be categorized into various types based on their function, such as directional valves, pressure valves, and flow valves. During production and maintenance, hydraulic valves require testing to verify that their performance meets design requirements. Hydraulic valve test benches are primarily used to support and mount hydraulic valve testing equipment.

[0003] At present, during the installation and use of test benches for hydraulic valves, the benches are generally welded and fixed. Once the welding is completed, the entire device is difficult to disassemble, which makes daily maintenance and inspection complicated. If a component fails, the entire device needs to be dismantled or cut for replacement, which increases maintenance time and cost. Not only that, the welded structure is not easy to modify or expand the design, which limits the flexibility and adaptability of the system. In addition, when the existing test bench is in use, the connected cables are generally hung above the bench, and the top position of the existing bench is fixed, which makes it difficult to organize the cables. Utility Model Content

[0007] A limiting column is fixed to the rear side of the top of the connecting frame, and a fixing shell is provided on the top of the limiting column surface. A cable rack is fixedly connected between the tops of the two fixing shells.

[0008] Preferably, a stop plate for preventing the use of the hydraulic valve is provided on the top of the connecting column, and the front and rear sides of the stop plate are both connected to the connecting column with screws.

[0009] Preferably, a groove is provided on the top of the connecting column, and a protrusion that cooperates with the groove is fixedly connected to the bottom of the abutment plate.

[0010] Preferably, a first mounting seat is installed on one side of the bottom of the support plate close to the connecting frame by screws, and a second mounting seat is installed on one side of the bottom of the connecting column close to the connecting frame and the supporting column by screws.

[0011] Preferably, sliders are fixedly connected to the front and rear sides of the limiting column, and sliding grooves for cooperating with the sliders are provided on the front and rear sides of the fixed shell.

[0012] Preferably, one side of the fixed shell is fixedly connected to the connecting shell, one side inside the connecting shell is fixedly connected to a spring, one side of the spring is fixedly connected to a clamping plate, the front and rear sides of one side of the clamping plate are fixedly connected to a pull rod, and the side of the pull rod away from the clamping plate passes through to the outside of the connecting shell and is fixedly connected to the pull plate.

[0013] Preferably, one side of the limiting column is fixedly connected to a toothed plate used in conjunction with the clamping plate, the surface of the pull rod is sleeved with a limiting ring, and one side of the limiting ring is fixedly connected to the connecting shell.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] The utility model first facilitates the installation between the support plate and the connecting frame through the first mounting seat, and facilitates the installation of the connecting column through the installation of the second mounting seat, the connecting frame and the support column, and the anti-plate can be conveniently installed at any position on the top of the connecting column through the cooperation of the protrusion, so as to facilitate the adjustment and installation according to the needs of use. Similarly, it is also convenient for disassembly and maintenance of the device. When the hydraulic valve test cables are all connected to the cable rack, the pull plate can be pulled to drive the pull rod to make the card plate squeeze the spring to make the card plate separate from the surface of the tooth plate, and then the fixed shell can be pulled up to straighten the cable, which is convenient for subsequent maintenance.
