Description

Technical Field

[0001] The present application relates to the technical field of pushers, and more specifically, to a pusher testing device. Background Art

[0002] The hydraulic pusher is an essential key component in the operation of various mechanisms of large-scale loading and unloading machinery. Failure of the hydraulic pusher will cause the brake system to fail, posing a safety risk. The main failures of the pusher are damage to the internal rotor bearing, loose internal impeller, pressure relief caused by damage to the guide ring seal, and pressure relief caused by wear of the piston and cylinder sleeve. The repaired pusher needs to be subjected to an overload pressure test to ensure that there is no pressure relief drop, no abnormal noise during operation, and no high temperature during long-term operation, etc., to ensure that the repaired pusher meets all requirements and meets the requirements for operation.

[0003] The document with prior art announcement number CN216771017U provides a hydraulic pusher maintenance and testing device, which drives the pull rod to move upward while the push rod of the pusher moves upward, and the upward movement of the pull rod will compress the spring; therefore, the push rod needs to overcome the compression force of the spring when moving upward. If the push rod can be moved upward and lifted smoothly, and there is no abnormal sound or heat during the upward movement, it means that the push rod can overcome the compression force of the spring, thereby realizing the pusher maintenance and repair test.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, the above-mentioned device is tested in the form of overcoming the compression force of the elastic member, which is different from the actual tile engagement braking form.

[0005] In view of the above-mentioned related technologies, the inventor believes that by setting a transmission wheel, a more realistic working state simulation test can be performed to improve the authenticity and effectiveness of the test. In view of this, we propose a thruster testing device. Utility Model Content

The arrangement of a plurality of counterweights 6 can be achieved by installing them on the transmission component 3, thereby increasing the inertia of the rotation of the wheel 5, thereby realizing the test of different loads.

[0036] A guide rail 11 is provided on the fixed seat 1, and the moving block 2 is slidably connected to the guide rail 11, so as to effectively guide the moving block 2 and ensure the accuracy of the moving position.
