[0018] The following further describes the present utility model in detail with reference to the drawings and through embodiments. The following embodiments are explanations of the present utility model, and the present utility model is not limited to the following embodiments.

[0019] Embodiment

[0020] See Figures 1 to 5 , in this embodiment, the hydraulic test platform is installed on the base 3 of the hydraulic test platform. The hydraulic test platform includes a test hydraulic cylinder 9, which is fixed to the front right side of the test platform. The support rod 6 is installed at the tail of the hydraulic rod of the test hydraulic cylinder 9. The stop block 5 is located inside the test groove 4. The tail plate 2 is located at the tail of the test groove 4. The earring 10 is located on the tail plate 2. The baffle 1 is located at the tail of the test groove 4. The fixing plate 7 is located in the middle position between the test hydraulic cylinder 9 and the test groove 4. The bolt 8 is located on the fixing plate 7.

[0021] In this embodiment, the hydraulic rod of the test hydraulic cylinder 9 extends into the test groove 4 through the hole in the front center of the platform; the test hydraulic cylinder 9 provides a load for the hydraulic cylinder to be tested.

[0022] In this embodiment, the support rod 6 is installed at the tail of the hydraulic rod of the test hydraulic cylinder 9, which is used to increase the contact area of the hydraulic rod during the test and reduce the wear of the test hydraulic rod.

[0023] In this embodiment, the stoppers 5 are located on the left and right sides in the middle of the test groove 4, which are used to prevent the hydraulic cylinder to be tested from moving left and right during the test. At the same time, for larger-sized hydraulic cylinders, they also play a role in restricting the front-back movement of the hydraulic cylinder.

[0024] In this embodiment, the test groove 4 is the test position for the hydraulic cylinder to be tested. During the test, the hydraulic cylinder to be tested needs to be placed horizontally in the test groove 4.

[0025] In this embodiment, the tail plate 2 is a detachable component, which is installed at the tail of the test groove 4 during the test; there are slots on the left and right sides of the tail plate 2 for fixing with the baffle 1. By placing the tail plate 2 between the left and right baffles along the slot direction, the fixation of the tail plate 2 on the test platform is realized. The tail plate 2 has two sides, the rear side is a flat structure. When testing non-earring hydraulic cylinders, the rear side is placed into the test groove 4 to provide a supporting force by directly contacting the bottom of the hydraulic cylinder to be tested. The front side is an earring structure, and there is an earring 10 fixed at each of the upper and lower positions on the front side. When testing earring hydraulic cylinders, the front side is placed into the test groove 4. The earring of the hydraulic cylinder to be tested is placed between the upper and lower earrings 10 on the front side of the tail plate 2, and the connection is realized by passing through the three earrings 10 with a pin shaft, which is used to provide a pulling force when testing earring hydraulic cylinders.

[0026] In this embodiment, there are two earrings 10 located at the upper and lower ends of the front side of the tail plate 2. When testing earring hydraulic cylinders, the earrings of the hydraulic cylinder to be tested are fixed by cooperating with the pin shaft to provide the pulling force required for the test of the hydraulic cylinder to be tested.

[0027] In this embodiment, the pin shaft is an independent component, which is a round steel with a diameter of 30 mm and a length of 400 mm as a whole. When testing earring hydraulic cylinders, it is used to prevent the hydraulic cylinder to be tested from moving forward by passing through the earrings 10. Since this component has a simple structure and is only used in the test of earring hydraulic cylinders, it is not marked separately.

[0028] In this embodiment, the baffle 1 is located at the tail of the test groove 4, which is used to realize the disassembly and installation of the tail plate 2 by cooperating with the slots on the left and right sides of the tail plate 2.

[0029] The test hydraulic cylinder 9 of the hydraulic test platform in this embodiment is used to provide the required load during the test. By controlling the extension and retraction of the hydraulic rod of the hydraulic cylinder, the test thrust and tension required for the hydraulic cylinder to be tested can be provided respectively. By applying a load to the hydraulic cylinder to be tested, it is tested whether there are phenomena such as oil leakage and unstable operation.

[0030] The fixing plate 7 in this embodiment is located in the middle position between the test hydraulic cylinder 9 and the test groove 4. The fixing plate 7 has a central hole, and the test hydraulic cylinder 9 passes through the central hole of the fixing plate 7, which is used to prevent the test hydraulic cylinder 9 from deviating from the horizontal state under its own gravity. At the same time, the fixing plate 7 is connected to the test groove 4 through bolts 8 to fix the position of the test hydraulic cylinder 9 and prevent the test hydraulic cylinder 9 from moving under force during the test, affecting the accuracy of the test results.

[0031] The bolt 8 in this embodiment is used for the connection and fixation between the fixing plate 7 and the test groove 4 and is located on the fixing plate 7.

[0032] The test groove 4 is the fixed position for the hydraulic cylinder to be tested. The side blocks 5 of the test groove 4 limit the left - right movement of the hydraulic cylinder to be tested in the horizontal direction, preventing it from changing its position under pressure during the test, causing unnecessary errors or machine damage.

[0033] The hydraulic test platform in this embodiment tests the actual performance of the hydraulic cylinder in an unknown state to check whether there are problems such as oil leakage, insensitive operation, and crawling.

[0034] Through the above description, those skilled in the art can already implement it.

[0035] In addition, it should be noted that for the specific embodiments described in this specification, the shapes and names of their components can be different. The above - described content in this specification is only an example of the structure of the present invention. Any equivalent changes or simple changes made according to the structure, features, and principles described in the patent concept of the present invention are included in the protection scope of the patent of the present invention. Those skilled in the technical field to which the present invention belongs can make various modifications, supplements, or use similar methods to replace the specific embodiments described, as long as they do not deviate from the structure of the present invention or exceed the scope defined by the claims of this patent, they should all belong to the protection scope of the present invention.
