Rotary holes are opened on both sides of the support frame, and a rotating shaft is rotatably connected within the rotating holes. A connecting plate is fixedly connected to one end of the rotating shaft. A mounting frame is fixedly connected between the two connecting plates. The upper surface of the mounting frame has two cavities for placing the reinforcement plate. A limiting cavity is opened at one end of the rotating shaft. A pull rod is slidably connected within the limiting cavity. Multiple guide grooves are opened on the outer side of the pull rod. Multiple stops are fixedly connected within the limiting cavity, and the stops are slidably connected to the guide grooves. A fixing mechanism for fixing the reinforcement plate is provided on the upper surface of the mounting frame. A limiting mechanism to prevent the mounting frame from rotating is provided on both sides of the support frame.

[0009] Furthermore, the limiting mechanism one includes two second slide grooves, which are respectively opened on the inner walls of both sides of the support frame. Limiting claws are slidably connected in each of the two second slide grooves. Multiple claw grooves are opened on the opposite sides of the two connecting discs, and the limiting claws are inserted into the claw grooves. Two slides are fixedly connected on the opposite sides of the two limiting claws, and the slides pass through the second slide grooves.

Ring plates are slidably connected in each of the two second slide grooves, and the ring plates contact the limiting claws. A spring is fixedly connected to one side of the ring plate, and the spring is fixed to the second slide groove. Positioning grooves are opened on one side of each of the multiple slides. Limiting mechanisms two for limiting the slides are provided on the outer walls of both sides of the support frame.

[0010] Based on the aforementioned scheme, the second limiting mechanism includes two elliptical discs, which are rotatably connected to the outer walls of the two sides of the support frame. Multiple first sliding grooves are provided on both sides of the outer walls of the support frame. The same limiting frame is slidably connected in two adjacent first sliding grooves.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides an auxiliary mechanism for reinforced plate anti-collision testing, which has the following beneficial effects:

[0018] 1. By using the limiting mechanism and the connecting plate together, the limiting mechanism can stop limiting the mounting frame. At this time, the mounting frame can be rotated to the other side. Then, the limiting mechanism can limit the mounting frame again. At this time, the other side of the reinforcing plate can be tested. Thus, both sides of the reinforcing plate can be tested, thereby improving the test data of the reinforcing plate.

[0019] 2. By setting the second limiting mechanism, after pulling the slide carriage so that the first limiting mechanism no longer limits the connecting plate, the second limiting mechanism limits the slide carriage, thereby preventing the first limiting mechanism from resetting and improving the convenience of using the test auxiliary mechanism.

[0020] 3. By setting up a fixing mechanism, the reinforcing plate is placed in the cavity and then fixed in place, preventing the reinforcing plate from falling off during the rotation of the mounting frame and improving the stability of the testing auxiliary mechanism.

[0021] 4. With the setting of fixing holes, after the test auxiliary mechanism is placed on the ground, the staff can use fixing bolts to fix the test auxiliary mechanism through the fixing holes on the base plate, so as to prevent the test auxiliary mechanism from shifting and improve the stability of the test auxiliary mechanism.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figures 1-7 A reinforcement plate anti-collision testing auxiliary mechanism includes a support frame 5. A hydraulic cylinder 7 is bolted to the top of the support frame 5. One end of the hydraulic rod of the hydraulic cylinder 7 passes through the support frame 5 and is bolted to a pressure head 6. Rotary holes are provided on both sides of the support frame 5, and a rotating shaft 15 is rotatably connected within each hole. A connecting plate 14 is bolted to one end of the rotating shaft 15. A mounting frame 1 is bolted between the two connecting plates 14. Two cavities 13 for placing the reinforcement plate are provided on the upper surface of the mounting frame 1. A limiting cavity 34 is provided at one end of the rotating shaft 15. A pull rod 32 is slidably connected within the limiting cavity 34. Multiple guide grooves are provided on the outer side of the pull rod 32. Multiple stops 35 are welded into the limiting cavity 34, and the stops 35 are slidably connected to the guide grooves. A fixing mechanism for fixing the reinforcement plate is provided on the upper surface of the mounting frame 1. Anti-mounting brackets are provided on both sides of the support frame 5. The first limiting mechanism for rotation places the reinforcing plate into the cavity 13 and fixes it using a fixing mechanism. The hydraulic cylinder 7 extends, pushing the pressure head 6 downwards to collide with the reinforcing plate, thus testing it. After testing, the hydraulic cylinder 7 retracts, causing the pressure head 6 to reset, and the first limiting mechanism no longer limits the connecting plate 14. At this point, the rotating shaft 15 can be rotated, causing the connecting plate 14 to rotate, which in turn causes the mounting bracket 1 to rotate, thus flipping the reinforcing plate. After the reinforcing plate flips to the other side, the first limiting mechanism again limits the connecting plate 14, thus limiting the angle of the rotating mounting bracket 1. Then, the hydraulic cylinder 7 extends again to test the other side of the reinforcing plate, allowing for testing of both sides and thus providing comprehensive test data.

[0032] In particular, the limiting mechanism of this invention includes two second sliding grooves 29, which are respectively formed on the inner walls of both sides of the support frame 5. Limiting claws 22 are slidably connected within each of the two second sliding grooves 29. Multiple claw grooves 23 are formed on opposite sides of the two connecting discs 14, and the limiting claws 22 are inserted into the claw grooves 23. Two slides 19 are welded to opposite sides of the two limiting claws 22, and the slides 19 pass through the second sliding grooves 29 and contact the pull rod 32. Multiple limiting grooves 27 are formed at one end of the rotating shaft 15, and the slides 19 are engaged with the limiting grooves 27. Annular plates 25 are slidably connected within each of the two second sliding grooves 29, and the annular plates 25 contact the limiting claws 22. A spring 26 is welded to one side of the annular plate 25, and the spring 26 is connected to the second sliding groove. 29 are fixed in phase. Positioning grooves 28 are provided on one side of each of the multiple carriages 19. Limiting mechanisms two for limiting the movement of the carriages 19 are provided on both outer walls of the support frame 5. Each limiting mechanism includes two elliptical discs 20, which are rotatably connected to the outer walls of the support frame 5. Multiple first sliding grooves 16 are provided on both outer walls of the support frame 5. The same limiting frame 18 is slidably connected within two adjacent first sliding grooves 16, and the limiting frame 18 engages with the positioning grooves 28 and contacts the elliptical discs 20. An elastic rope 17 is bonded between two limiting frames 18 on the same side. A handle 21 is fixed to one side of the elliptical disc 20 by bolts. Pulling the pull rod 32 moves it outward from the limiting cavity 34 until a stop block 35 blocks the pull rod 32, preventing further movement. Then, pull the slide 19. The slide 19 will drive the limiting claw 22 to move into the second slide groove 29. The limiting claw 22 will squeeze the ring plate 25 to move, and the ring plate 25 will squeeze the spring 26. When the limiting claw 22 moves to disengage from the claw groove 23, rotate the elliptical disk 20. During the rotation of the elliptical disk 20, the two limiting brackets 18 on the same side will move towards each other along the first slide groove 16 under the force of the elastic rope 17. When the elliptical disk 20 rotates to a certain angle, the limiting brackets 18 will engage with the positioning groove 28, thereby limiting the slide 19. At this time, the rotating shaft 15 can be rotated. After the reinforcing plate flips to the other side, the elliptical disk 20 is reversed. During the rotation of the elliptical disk 20, its protruding part will push the two limiting brackets 18 along the first slide groove 16. Moving in the opposite direction, the two limiting brackets 18 will stretch the elastic rope 17, causing it to generate elastic force. Simultaneously, the limiting brackets 18 will disengage from the positioning groove 28. At this time, under the force of the spring 26, the ring plate 25 will move, pushing the limiting claw 22 outwards into the second sliding groove 29, allowing the limiting claw 22 to re-engage with the claw groove 23 on the connecting plate 14. The fixing mechanism includes multiple slots 10, all located on the upper surface of the mounting bracket 1. Two opposing slots 10 are slidably connected to the same baffle 11. The upper surface of the baffle 11 is provided with screws 8. The upper surface of the mounting bracket 1 has two positioning holes 12, with the screws 8 passing through the baffle 11 and threadedly connected to the positioning holes 12. An auxiliary plate 9 is welded to the upper surface of the baffle 11.The baffle 11 is placed into the slot 10 to block the reinforcing plate, and the baffle 11 is fixed by connecting the screw 8 to the positioning hole 12. An installation hole is provided on the outer side of the pull rod 32, and an auxiliary rod 31 is welded into the installation hole. The operator can rotate the pull rod 32 through the auxiliary rod 31. A first magnetic block 33 is fixed in the limiting cavity 34 by bolts. A second magnetic block 36 is fixed to one end of the pull rod 32 by bolts, and the first magnetic block 33 and the second magnetic block 36 are attracted to each other. During the movement of the pull rod 32, the second magnetic block 36 will move, causing the second magnetic block 36 to disengage from the first magnetic block 33. Multiple claw slots 23 have chamfered angles 30 on multiple sides, which facilitate the entry of the limiting claw 22 into the claw slot 23. The bottom of the support frame 5 is fixed to the base plate 3 by bolts. Multiple fixing holes 2 are provided on the upper surface of the base plate 3, and multiple support ribs 4 are welded to the upper surface of the base plate 3. The support ribs 4 are fixed to the support frame 5, and the support ribs 4 can enhance the stability of the connection between the base plate 3 and the support frame 5.

[0033] The working principle of this embodiment is as follows: During use, the reinforcing plate is placed into the cavity 13, then the baffle 11 is placed into the slot 10 to block the reinforcing plate. The baffle 11 is fixed by connecting the screw 8 to the positioning hole 12. Then, the hydraulic cylinder 7 extends, pushing the pressure head 6 downwards to collide with the reinforcing plate, thus testing the reinforcing plate. After the test, the hydraulic cylinder 7 retracts, causing the pressure head 6 to reset. Then, the pull rod 32 is pulled out of the limiting cavity 34. The pull rod 32 will move the second magnetic block 36, causing the second magnetic block 36 to move. 6 disengages from the first magnetic block 33 until the stop block 35 blocks the pull rod 32 from moving. Then, the slide 19 is pulled, and the slide 19 will drive the limiting claw 22 to move into the second slide groove 29. The limiting claw 22 will squeeze the ring plate 25 to move, and the ring plate 25 will squeeze the spring 26. When the limiting claw 22 moves to disengage from the claw groove 23, the elliptical disk 20 is rotated. During the rotation of the elliptical disk 20, the two limiting brackets 18 on the same side will move towards each other along the first slide groove 16 under the force of the elastic rope 17. When the elliptical disk 20 rotates, the two limiting brackets 18 on the same side will move towards each other along the first slide groove 16. After rotating to a certain angle, the limiting bracket 18 will engage with the positioning groove 28, thereby limiting the slide 19. At this time, the rotating shaft 15 can be rotated, which will drive the connecting plate 14 to rotate. The connecting plate 14 will drive the mounting bracket 1 to rotate, thereby flipping the reinforcing plate. When the reinforcing plate is flipped to the other side, the elliptical disc 20 will be reversed. During the rotation of the elliptical disc 20, its protruding part will push the two limiting brackets 18 to move in opposite directions along the first slide groove 16. The two limiting brackets 18 will stretch the elastic rope. 17. The elastic rope 17 generates elasticity, which will cause the limiting frame 18 to disengage from the positioning groove 28. At this time, under the action of the spring 26, the ring plate 25 will be pushed to move. The ring plate 25 will push the limiting claw 22 to move out of the second slide groove 29, so that the limiting claw 22 can re-engage with the claw groove 23 on the connecting plate 14, thereby limiting the angle after the mounting frame 1 rotates. Then, the hydraulic cylinder 7 is started again to extend and test the other side of the reinforcing plate. Both sides of the reinforcing plate can be tested, thereby improving the test data of the reinforcing plate.
