[0003] For newly developed motorcycles, after the motorcycle is assembled, a series of tests need to be carried out to ensure the rationality of the later motorcycle design, to ensure safety, stability and durability during use. Among them, the motorcycle front pipeline durability test is an important test item. This project is to test whether the motorcycle head has an impact on the pipeline during the left and right swing, and whether it will cause wear of the oil pipe and wire, so as to prevent the wear of the pipeline when the motorcycle head turns left or right during later use, and to detect whether the strength of the oil pipe meets the requirements; currently, when conducting the motorcycle front pipeline durability test, manual testing is used, the test time is long, time-consuming and labor-intensive, and the labor cost is increased.

When the air pressure pump moves downward, the front of the motorcycle is pulled to another direction through the gravity of a return block. The above actions are repeated to perform a left-right steering durability test for the front pipeline of the motorcycle. Workers only need to fix the position of the motorcycle to perform uninterrupted testing, which not only saves labor costs and reduces the workload of workers, but also makes the test more accurate.

The support column is arranged between the second fixed plate and the first fixed plate to play a buffering role, thereby reducing the impact of the air pump on the whole when the air pump is in operation and reducing the vibration of the whole equipment.

Workers only need to fix the position of the motorcycle to perform uninterrupted testing, which not only saves labor costs and reduces the workload of workers, but also makes the test more accurate;

[0029] The travel of the balance block is limited by setting the limit hole and the limit bolt. Since the test needs to be carried out hundreds or thousands of times, in order to ensure that the balance block does not vibrate greatly each time the air pump is actuated, the balance block is limited in the left and right directions by setting the limit plate, thereby ensuring that the motorcycle does not shake during the test, thereby ensuring the test effect.
