Specific embodiments

[0031] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments:

[0032] As Figures 1-9 shown, the vehicle debris piercing test equipment includes a gantry, the gantry includes columns 11 symmetrically arranged on both sides and a cross beam 1 located at the top of the columns 11. First accommodation grooves 12 and second accommodation grooves 13 are provided in both columns 11 on both sides. First guide rails 14 are installed in the first accommodation grooves 12. The shape of the cross beam 1 is set as the character 'gong' in Chinese characters.

[0033] It further includes a base 3 and an impact hammer 4. The base 3 is provided with a plurality of arranged third accommodation grooves 31, and the base 3 is further used to support the gantry and to place the workpiece to be tested for debris penetration. The impact hammer 4 is connected to a guide rod 41 and is placed below the guide rod 41. The impact hammer 4 is used to pierce the workpiece.

[0034] In this embodiment, a slider is slidably arranged on the first guide rail 14. A first moving motor 16 is fixedly arranged on the slider. The first moving motor 16 includes a first gear 18. A first rack 19 adapted thereto is provided in the inner cavity of the first guide rail 14. The first guide rail 14 is in transmission cooperation with the first moving motor 16 through the first rack 19.

[0035] A laterally arranged second guide rail 15 is connected between the first guide rails 14 on both sides. For example, both ends of the second guide rail 15 are respectively installed on sliders slidably arranged on the corresponding first guide rails 14. A sliding plate 22 is slidably arranged on the second guide rail 15. A second moving motor 17 is fixedly installed on the sliding plate 22. The second moving motor 17 includes a second gear 20. A second rack 21 adapted thereto is provided in the inner cavity of the second guide rail 15. The second guide rail 15 is in transmission cooperation with the second moving motor 17 through the second rack 21.

[0036] When the first moving motor 16 moves vertically in the first guide rail 14, the first moving motor 16 synchronously drives the second guide rail 15 to move vertically in the first guide rail 14. When the second moving motor 17 moves horizontally in the second guide rail 15, the second moving motor 17 synchronously drives the sliding block 22 to move together therewith.

[0037] Furthermore, a push-pull electromagnet 23 and a connecting plate 24 are installed on the sliding plate 22. The push-pull electromagnet 23 is placed on the top of the sliding plate 22. The sliding plate 22 is provided with gaps for cooperating and connecting with the connecting plate 24, and there are at least two such gaps. Both the push-pull electromagnet 23 and the connecting plate 24 are used for cooperating and connecting with the guide rod 41.

[0038] Specifically, an electromagnetic pin retaining ring 42 and a connecting block 43 are installed on the guide rod 41. The electromagnetic pin retaining ring 42 is placed below the connecting block 43. The connecting block 43 is used for fixedly connecting with the connecting plate 24. The push-pull electromagnet 23 is used for supporting the electromagnetic pin retaining ring 42. And through the magnetic force cooperation between the push-pull electromagnet 23 and the electromagnetic pin retaining ring 42, the guide rod 41 will not be affected by gravity to drive the impact hammer 4 to fall, causing additional safety hazards.

[0039] In addition, a limiting block 44 is also installed on the guide rod 41. Both the connecting plate 24 and the connecting block 43 are provided with through holes for passing through and connecting with the guide rod 41.

[0040] Furthermore, support beams 25 are connected to the bottoms of the columns 11 on both sides. Support columns 26 in an inclined state are installed on the support beams 25. One end of each support column 26 is connected to the second accommodation groove 13 of the column 11. A reinforcing beam 27 is also installed between the support columns 26 on both sides. The reinforcing beam 27 is used to reinforce the supporting strength of the support columns 26, so that the support beam 25 can better support the column 11 and the cross beam 1 at the top of the column 11.

[0041] The shape of the support beam 25 is also set as the shape of the character "工" in Chinese. At least two casters 28 are installed at the bottom of each support beam 25. At least four screw units 29 are installed at the edges of the bottom of the shape of the character "工". At least a part of the screw units 29 is placed in the third accommodation groove 31.

[0042] In this embodiment, as one operating method, the present invention also includes a PLC intelligent control system. The operator uses the PLC control system to intelligently control the first moving motor 16 to be in a moving state and synchronously drive the second guide rail 15 to descend. During the descent of the second guide rail 15, the impact hammer 4 descends synchronously, and the second moving motor 17 drives the impact hammer 4 to move laterally so that the impact hammer 4 is located directly above the workpiece.

[0043] Next, the operator continues to lower the impact hammer 4 using the first moving motor 16 so that it can come into contact with the workpiece. Specifically, the wooden rod included in the impact hammer 4 can touch the workpiece.

[0044] Subsequently, the operator once again uses the first moving motor 16 to synchronously drive the second guide rail 15 to rise, raising the impact hammer 4 to the designated height for testing. The PLC intelligent control system then de-energizes the push-pull electromagnet 23. After de-energization, the push-pull electromagnet 23 no longer supports the electromagnetic pin retaining ring 42. Under the influence of gravity, the guide rod 41 drives the impact hammer 4 to fall and release. During the falling and releasing process, the guide rod 41 always ensures that the impact hammer 4 remains in a vertical state.

[0045] The limiting block 44 ensures that the impact hammer 4 will not touch the ground during the falling and release process, specifically the wooden rod included in the impact hammer 4.

[0046] After the release process is completed, the operator controls the first moving motor 16 to lower the second guide rail 15, and reconnects the sliding plate 22 with the guide rod 41.

[0047] 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.
