[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model uses a base, column, adjustment frame, mounting base, and extension arm to form a frame that can suspend the impacting object. The suspension rope acts as a rotating arm, pulling the suspended impacting object backward and upward to release it. Under the action of gravity, the impact detection effect is formed. There is no need to directly pick up the impacting object for impact, which saves more effort. Moreover, the height of the impacting object being pulled backward and upward can be controlled, thus forming a stable impact force.

[0019] This invention uses a first reduction gear, a first gear plate, and a second gear plate to drive a first winding disc, thereby enabling the winding and unwinding of the first suspension rope and controlling the linear distance between the impacting object and the fixed pulley. Furthermore, the actual support height of the support assembly can be controlled by rotating the threaded sleeve in conjunction with the threaded strut. The setting height of the support assembly can be controlled by adjusting the position of the movable sleeve on the diagonal strut, thereby controlling the support height at the end of the extension arm.

[0020] This utility model has a foldable front support leg on the front side of the base and a foldable rear support leg on the rear side of the base. When in use, the front and rear support legs are unfolded to form a larger support area and provide stable support.

[0021] This invention uses a second reduction gear to drive a second take-up reel, which allows the tail end of the boom to be lifted by a second lifting rope. The boom can be connected to a first lifting ring via a pin, thereby controlling the height of the impactor and facilitating the formation of a stable impact force.

[0022] The adjusting frame is connected to the column by a slider and a guide rail. The third reduction gear and the third winding reel wind up the third hoisting rope. The adjusting frame can be raised and lowered by the cooperation of the hanging rod, fixed pulley and movable pulley, thereby adjusting the overall height of the device.

[0023] The front and rear support feet of this utility model can be folded relative to the base and column. The support components and diagonal braces can be removed from between the column and the support feet. At the same time, the support components can be detached from the extension arm. Thus, the extension arm and the boom can be folded relative to each other, thereby disassembling and folding the device, which facilitates the handling and transfer of the device.

[0047] The front support leg 3 and the rear support leg 4 can be folded relative to the base 1 and the column 2. The support component 9 and the diagonal brace 10 can be removed from between the column 2 and the support leg 4. At the same time, the support component 9 can be removed from the extension arm 7. Thus, the extension arm 7 and the boom 34 can be folded relative to each other, thereby disassembling and folding the device, which facilitates the handling and transfer of the device.

[0048] The working principle of this utility model is as follows:

[0049] In use, the overall folding structure consisting of base 1, column 2, front support leg 3, rear support leg 4, adjustment frame 5, mounting base 6, extension arm 7, and boom 34 is moved using wheels 30. Simultaneously, the support assembly 9 and diagonal brace 10 are moved, and the device is moved to the outside of the guardrail where soft heavy object impact testing is required. The front support leg 3 is unfolded and further secured using the first fixing bolt 44. Then, the rear support leg 4 is unfolded, providing support for the device. The diagonal brace 10 is then installed between the column 2 and the front support leg 3 using the second fixing bolt 19. The position of the movable sleeve 22 on the diagonal brace 10 can be adjusted to change the initial support height of the support assembly 9, which is then locked in place using the first tightening bolt 23. Finally, the round rod 28 is inserted through the round sleeve 29 and connecting sleeve 26, providing support for the support assembly 9 and extension arm 7. At this point, by tightening the second clamping bolt 27, the round rod 28 is fixed to the connecting sleeve 26. Further rotation of the threaded sleeve 24 allows the round rod 28 to be lifted by the threaded support rod 25, further adjusting the support of the extension arm 7 and controlling the support height of the fixed pulley 15. The impact object 8 is then hooked onto the first lifting ring 17 via the first hook 18. The second lifting rope 33 is then passed through the second lifting ring on the boom 34 and fixed at its end by a rope clamp. At this point, the first reduction gear 14, the second reduction gear 31, and the third reduction gear 37 can be driven by power tools. The rotation of the first reduction gear 14 drives the rotation of the second gear disc 13. The second gear disc 13 rotates through the first gear disc 17. The first take-up reel 11 is rotated by the second gear 31 to wind up and unwind the first hoisting rope 16. The second gear reducer 31 can drive the second take-up reel 32 to rotate, thereby wind up and unwind the second hoisting rope 33. This allows control over the tilt of the boom 34 and the suspension height of its tail end. The third gear reducer 37 drives the third take-up reel 43 to rotate, thereby winding up the third hoisting rope 41. The end of the third hoisting rope 41 is hooked onto the hanging rod 38 by the second hook 42 to form a fixed position. The tightened third hoisting rope 41 drives the adjusting frame 5 through the fixed pulley 39 and the movable pulley 40. The adjusting frame 5 is adjusted relative to the column 2 by the cooperation of the slider 36 and the guide rail 35, thereby adjusting the overall height of the device. At this point, the impactor 8 can be pulled backward and upward to form an arc-shaped movement trajectory until the first lifting ring 17 corresponds to the pin sleeve 45. At this point, the pin 46 can be pushed out and inserted into the first lifting ring 17 by the push rod 47 to form a positioning effect. At this point, the pin 46 can be pulled out, thereby releasing the impactor 8. At this point, under the action of the first lifting rope 16, the impactor 8 forms an arc-shaped movement trajectory under the action of gravity, thereby causing the impactor 8 to collide with the guardrail, and conducting a soft heavy object anti-collision test for the building guardrail.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
