Description

Technical Field

[0001] This utility model relates to the technical field of single-prop test benches, and in particular to a test bench for the maintenance of one-way valves of single hydraulic props used in mining. Background Technology

[0002] The single-prop test bench integrates a press device to form an integrated system of "hydraulic loading and performance testing": the press module uses a high-precision hydraulic cylinder and provides stable axial loading force through a frame structure to simulate roof pressure; the test bench retains its original functions and is equipped with a high-precision sensor and data acquisition system to monitor the prop's sealing performance, strength, and three-way valve setting performance in real time. The two are switched through a quick-reversing valve to achieve working condition switching, taking into account both overall prop testing and component-level testing, improving maintenance efficiency by more than 30%, and is suitable for the comprehensive testing needs of underground coal mines and surface maintenance workshops.

[0003] When using a single-support test bench, the hydraulic supports need to be placed on the press equipment. However, since the test bench lacks an automatic feeding structure, it can only rely on manual handling or lifting tools to complete the feeding. Manual handling is labor-intensive and it is difficult to accurately control the position of the supports. Although lifting reduces the physical burden, the hydraulic supports still cannot be quickly positioned and need to be repeatedly adjusted to align with the mounting holes, which takes a long time. In addition, the existing feeding method is not adaptable to hydraulic supports of different specifications and volumes, and it is necessary to frequently change the lifting tools or adjust the operation method, resulting in low feeding efficiency. This seriously affects the ease of operation and overall testing efficiency of the single-support test bench.

[0004] Therefore, in response to the above problems, a new test bench for overhauling one-way valves of single hydraulic props for mining is proposed. Utility Model Content

[0005] To overcome the problems existing in related technologies, this utility model provides a test bench for the maintenance of one-way valves of single hydraulic props in mining. It can install an automatic feeding structure on a transport trolley to quickly place hydraulic props of different specifications onto the press equipment, thereby improving the convenience of the single prop test bench.

[0006] To achieve the above objectives, the first aspect of this utility model provides a test bench for overhauling one-way valves of single hydraulic props used in mining, comprising:

[0007] The main body of the testing machine, the main body of the press, the main body of the trolley, the support frame, and the placement base;

[0008] The main body of the testing machine is equipped with a press body on one side, a trolley body on the other side, a support frame on top of the trolley body, a placement seat symmetrically fixedly connected to the top of the support frame, movable seats on both sides of the placement seat, and clamping blocks fixedly connected to the upper surface of the movable seats.

[0009] Furthermore, a protective shell is symmetrically fixedly connected to the placement base. A transmission gear is rotatably connected inside the protective shell. A first rack is slidably connected inside the protective shell and meshes with the transmission gear. A second rack is slidably connected to the protective shell below the first rack. The second rack meshes with the transmission gear. Both the first rack and the second rack are fixedly connected to the movable base.

[0010] Furthermore, a first electric push rod is fixedly connected to the inner wall of the placement seat, and the moving end of the first electric push rod is fixedly connected to the right movable seat.

[0011] Furthermore, the first electric push rod is provided with guide rods on both sides that are fixedly connected to the inside of the placement seat, and the guide rods slide through the movable seat.

[0012] Furthermore, a support base is fixedly connected to the main body of the trolley, and a second electric push rod is symmetrically fixedly connected inside the support base. The moving end of the second electric push rod is fixedly connected to the lower surface of the support frame.

[0013] Furthermore, a lifting groove is provided inside the support base, and a T-shaped rod is provided between the two second electric push rods and fixedly connected to the lower surface of the support frame. The T-shaped rod is slidably connected to the lifting groove.

[0014] Furthermore, the support base has four reinforcing buckles that are symmetrically bolted together, and these buckles are bolted to the main body of the trolley.

[0015] The technical solution provided by this utility model can include the following beneficial effects:

[0016] In this example, the hydraulic support is placed on the surface of the placement seat by installing the placement seat, movable seat, and clamping block. The two movable seats move closer or further apart from each other with the placement seat as the center.
