[0028] The following further describes the present utility model in detail in conjunction with the accompanying drawings and specific implementation manners:

[0029] As Figures 1-7 shown, the debris piercing test equipment includes a lifting overhead crane 1, a support beam 2 and an equipment frame 3. Slide rails 11 are installed on both sides of the lifting overhead crane 1. Chutes 12 are opened at the bottoms of the two slide rails 11. A trolley 13 is installed in the chute 12. The support beam 2 is in the shape of the Chinese character "工" (工字), and the extended edges thereof are used for sliding connection with the first electric hoist 21 and the second electric hoist 22.

[0030] In this embodiment, the two slide rails 11 are both in the shape with several hollow parts in the middle. Placement openings for placing the second connecting component 15 are opened at the bottoms of the two trolleys 13. The trolley 13 is slidably connected to the support beam 2 through the second connecting component 15, and the support beam 2 can be connected in cooperation with the lifting overhead crane 1.

[0031] The trolley 13 is also equipped with several pulleys 14. Through the pulleys 14, the trolley 13 can move longitudinally in the chute 12. And when the trolley 13 moves longitudinally in the chute 12, the trolley 13 synchronously drives the support beam 2 to move together.

[0032] Further, the first electric hoist 21 includes a first hook 23 and a pulling rope 24. The pulling rope 24 is wound inside the first electric hoist 21. A fixing fitting for positioning the pulling rope 24 is opened at one end of the first electric hoist 21. The first hook 23 is used for hoisting the piercing equipment, and the piercing equipment includes the equipment frame 3.

[0033] Specifically, guide rods 27 are also installed on both sides of the first electric hoist 21. At least two guide rods 27 are installed on each side. The equipment frame 3 is slidably connected to the guide rods 27. The guide rods 27 are used to ensure that the equipment frame 3 always remains in the vertical direction. And, a first square plate with a circular hole in the middle is assembled at one end of the guide rod 27, and a second square plate with a square hole in the middle is installed at the other end. There is a certain distance between the first square plate and the second square plate up and down, and at least a part of the first hook 23 is placed inside the first square plate.

[0034] Furthermore, the equipment frame 3 is rectangular in shape with a certain length and open on three sides. A linear motor 32 is installed on the non-open side. An impact hammer 31 is installed at one end of the linear motor 32. Both the linear motor 32 and the impact hammer 31 are placed in the inner cavity of the equipment frame 3. The linear motor 32 includes a slider assembled on itself. An electrical box 35 is installed opposite the linear motor 32 and is detachably connected to the equipment frame 3. The electrical box 35 is used to house electrical control components.

[0035] A first connecting component 36 is assembled between the linear motor 32 and the impact hammer 31. Through the first connecting component 36, the linear motor 32 and the impact hammer 31 are slidably engaged. The linear motor 32 is also used to control the impact hammer 31 to rise to the precise distance for testing.

[0036] One end of the first connecting component 36 is connected to an electromagnet 34, which is in turn connected to the impact hammer 31 and placed on top of the impact hammer 31. The electromagnet 34 is used to prevent the impact hammer 31 from falling and being released under the influence of gravity during the process of the linear motor 32 controlling the impact hammer 31 to rise. During this process, the electromagnet 34 needs to be kept energized.

[0037] Symmetrical electromagnetic pins 38 are also installed on both sides of the first connecting component 36. The electromagnetic pins 38 are used to ensure that the impact hammer 31 is connected to the equipment frame 3 when the present invention is not in use, so as to prevent additional safety hazards.

[0038] Furthermore, steel wire ropes 33 are fixedly connected to both sides of the equipment frame 3. The steel wire ropes 33 are slidably connected to the impact hammer 31. The steel wire ropes 33 always remain vertical whether the impact hammer 31 is rising or falling. In addition, rubber blocks 37 are installed between the impact hammer 31 and the equipment frame 3, and the rubber blocks 37 play a buffering role during the descent and release of the impact hammer 31.

[0039] In this embodiment, the second electric hoist 22 includes a second hook 25 and a hook bag 26. The second electric hoist 22 is used to lift the vehicle frame through the second hook 25, and the hook bag 26 can be used to hold the second hook 25.

[0040] During the use of this utility model, the operator controls the various equipment parts through the PLC control system to complete the adjustment of the vehicle inspection points.

[0041] As one testing method, the operator uses the second electric hoist 22 and the second hook 26 to lift the vehicle frame and place it at the test point. It should be noted that this utility model is only used for testing the vehicle frame of recreational off-road vehicles.

[0042] Subsequently, preliminary adjustments were made by controlling the first electric hoist 21. After lowering the equipment frame 3 by pulling the rope 24 so that the impact hammer 31 is directly above the test point of the vehicle frame, the operator raised the impact hammer 31 to a certain distance by using the linear motor 32. Then, the first electric hoist 21 was used again to make the impact hammer 31 contact the vehicle frame, that is, the wooden rod included in the impact hammer 31 could contact the vehicle frame.

[0043] After the impact hammer 31 contacts the frame, the operator raises the impact hammer 31 to the precise test height again using the linear motor 32. Then, the electromagnet 34 is de-energized through the PLC control system. Under the influence of gravity, the impact hammer 31 falls and is released, always maintaining a vertical position during the fall and release.

[0044] After the test, the operator once again used the linear motor 32 to lower the first connecting part 36 to the designated position, and then used the electromagnet 34 and the electromagnetic pin 38 to re-install it with the impact hammer 31.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
