Description

Technical Field

[0001] This utility model belongs to the field of coal mine tunneling machine reducer testing, and in particular relates to an adjustable coal mine tunneling machine reducer testing device. Background Technology

[0002] Testing the speed reducer of a coal mine tunneling machine is a crucial step in ensuring equipment performance and safety. As a core component of the tunneling machine, the speed reducer's performance directly impacts the overall efficiency and reliability of the equipment. Therefore, rigorous testing is essential before the speed reducer is put into use to verify that its performance indicators meet design requirements. These tests are typically conducted on specialized test benches, simulating loads and speeds under actual working conditions. Through rigorous testing, not only can the speed reducer's performance be ensured to meet design requirements, but it also provides a strong guarantee for the long-term stable operation of the equipment.

[0003] Comparing with Chinese Patent CN221506275U, an experimental device for a cutting reducer in a coal mine tunneling machine is disclosed. The device includes an experimental frame, a lifting plate movably connected to one side of the frame, a limiting plate fixedly connected to the top of the lifting plate, a locking half-ring movably connected to the top of the limiting plate, a rubber half-ring installed at the bottom of the locking half-ring, and multiple sets of clamping springs fixedly connected to the outer side of the rubber half-ring in a ring-like arrangement. A movable positioning plate is movably connected inside the limiting plate. The reducer body is clamped by the rebound force of the clamping springs on the rubber half-ring inside the locking half-ring and the return spring at the bottom of the movable positioning plate. The locking half-ring is locked and pressure is applied to the springs through the threaded connection of the locking bolts and locking threaded holes. This achieves the device's function of clamping and fixing the reducer, preventing detachment and shaking during the experiment and lifting process, thus avoiding any impact on the experimental results.

[0004] However, the aforementioned patent can only adjust the height vertically, and cannot be used to test the reducer of a coal mine tunneling machine that is misaligned in the horizontal direction, which greatly limits the scope of applicable testing for the reducer of the coal mine tunneling machine. Therefore, a new device needs to be designed. Utility Model Content

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. By adjusting the height and position, the system ensures the testing of different coal mine tunneling machine reducers, thus expanding its applicability.

[0016] 2. The coordinated operation of the electric push rod and the servo motor enables precise adjustment of the height and horizontal position of the support platform and the worktable, improving the flexibility and efficiency of the experiment.
