[0002] In the field of industrial manufacturing and scientific research in universities, when factories process products and universities conduct scientific research experiments, it is necessary to conduct impact and collision resistance tests on samples or materials in order to obtain the performance indicators of the samples or materials. Therefore, an anti-collision test bench is needed.
[0003] In the prior art, there are some anti-collision test benches that use a connecting rope to bind a hammer for lifting. The connecting rope is reeled in by the rotation of a motor, and the hammer is pulled to a certain height and then released to perform an impact collision. The position limitation of the hammer completely relies on the self-locking effect of the motor, and there is no additional auxiliary locking device. Long-term use can easily cause damage to the motor. For this reason, we propose an anti-collision test bench. Utility Model Content

[0024] In this embodiment, the capstan 4 can be driven to rotate by the driving component to complete the winding and unwinding of the connecting belt 3, thereby driving the hammer 2 to be raised and lowered, and its height can be adjusted. The capstan 4 can be locked by the locking component to prevent it from rotating, which can play an auxiliary locking effect. Compared with the prior art, an additional set of auxiliary locking devices is provided, which makes it less likely that the motor 11 will be directly damaged, thereby helping to extend the service life of the motor 11.
[0025] Please refer to Figure 1-5 As shown, the locking assembly includes an inner spline 6, an outer spline 7 and a first electric push rod 8. The inner spline 6 is installed at one end of the capstan 4. The inner spline 6 can be connected to the outer spline 7 in a plug-in manner. The outer spline 7 is connected to the output end of the first electric push rod 8. The first electric push rod 8 is installed on one side of the support 5. The driving assembly includes a first gear 9, a second gear 10 and a motor 11. The first gear 9 is installed at the end of the capstan 4 away from the inner spline 6. The first gear 9 is meshed with the second gear 10, and the second gear 10 is connected to the output end of the motor 11.
[0026] In this embodiment, by contracting the first electric push rod 8, the outer spline 7 can be pulled to move and insert into the inner spline 6, which can be locked to complete the limiting of the capstan 4. Conversely, the limiting can be released. By starting the motor 11, the second gear 10 is driven to rotate, and the first gear 9 meshing with it is rotated, which can drive the capstan 4 to rotate and drive the connecting belt 3 to be reeled in and out, thereby completing the lifting and lowering of the hammer 2.

The two sets of clamp blocks 18 can be used to clamp the workpiece to fix it and prevent it from deviating, which helps to improve the accuracy of the test. The installed limiting roller 16 can be used to clamp and limit the connecting belt 3, so that it can keep sliding in the through hole 15 to reduce the wear of the connecting belt 3. By starting the motor 11, the second gear 10 is driven to rotate, and the first gear 9 meshing with it is rotated, which can drive the capstan 4 to rotate, drive the connecting belt 3 to be reeled and unreeled, and drive the hammer 2 to slide and rise and fall along the slide bar 13.
