[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In the present invention, by providing a pneumatic collision component, when performing a collision test on a three-dimensional model of a steel structure, first, through the PLC controller, the solenoid valve is opened, so that the high-pressure gas inside the high-pressure gas storage tank can enter the inside of the first connecting pipe through the hose. The gas reaches the piston through the first connecting pipe and the second connecting pipe, and then the piston can enter the inside of the third connecting pipe, thereby hitting the impact head. After the impact head bears the thrust of the piston, it disengages from the inside of the third connecting pipe, and then hits the positioned three-dimensional model of the steel structure, thereby performing a collision performance test on the three-dimensional model of the steel structure.

Then, one side of the three-dimensional model of the steel structure is positioned through the pressing plate, so that the impact head can move to the pre-impact point. Then, by adjusting the position of the second snap ring, the two second snap rings can position the three-dimensional model of the steel structure, and at the same time, the pressure borne by the three-dimensional model of the steel structure is relatively small. Furthermore, it can prevent the three-dimensional model of the steel structure from having a large degree of displacement during the collision test, affecting the accuracy of the test data. At the same time, under the action of the protective frame, it can prevent some components of the three-dimensional model of the steel structure from scattering and affecting the surrounding staff.

By setting the protective frame 2, it can prevent parts from splashing when the steel structure three-dimensional model is impacted by a large impact force, which may affect the safety of surrounding staff. A PLC controller 3 is arranged on the front surface of the base 1. By setting the PLC controller 3, it is convenient for staff to control the normal operation of each electronic component of this device. A plug board 4 is slidably connected inside the protective frame 2; by setting the plug board 4, it is convenient for staff to install and place the first connecting pipe 503 and the second connecting pipe 9. A pneumatic collision component 5 is arranged on one side of the base 1. By setting the pneumatic collision component 5, it is convenient for staff to control the impact force borne by the steel structure three-dimensional model, thereby improving the collision performance test efficiency. The pneumatic collision component 5 includes a high-pressure gas storage tank 501 arranged on one side of the base 1. By setting the high-pressure gas storage tank 501, high-pressure gas can be stored and then released to push the piston 10 to move, thereby controlling the impact force borne by the steel structure three-dimensional model. A hose 502 is arranged on the top of the high-pressure gas storage tank 501. By setting the hose 502, under the action of the hose 502, the gas inside the high-pressure gas storage tank 501 can be transported, so that the gas enters the inside of the first connecting pipe 503, and then the piston 10 can move smoothly. One end of the hose 502 is connected to a first connecting pipe 503. One end of the first connecting pipe 503 is provided with a third connecting pipe 504. By setting the third connecting pipe 504, after the piston 10 moves into the inside of the third connecting pipe 504, it can impact the impact head 11 placed inside the third connecting pipe 504, so that the impact head 11 can collide with the steel structure three-dimensional model. A laser velocimeter 505 is arranged on the top of the base 1; by setting the laser velocimeter 505, under the action of the two laser velocimeters 505, the flying speed of the impact head 11 can be detected, and then the kinetic energy carried by the impact head 11 can be calculated. A positioning component 6 is arranged on the top of the base 1. By setting the positioning component 6, it is convenient for staff to position the steel structure three-dimensional model through the positioning component 6, so that the impact head 11 can move to the preset impact position. The positioning component 6 includes a card slot 601 opened inside the base 1. By setting the card slot 601 and the pressing plate 602, it is convenient for staff to adjust the position of the pressing plate 602, so that the pressing plate 602 can position one side of the steel structure three-dimensional model. The pressing plate 602 is slidably connected inside the base 1. A first fixing rod 603 is slidably connected inside the pressing plate 602. By setting the first fixing rod 603, the pressing plate 602 can move stably, and then position and place the steel structure three-dimensional model placed at the specified position. A pressing rod 604 is slidably connected inside the base 1,

[0030] Reference Figure 1 and Figure 2As shown, an air outlet pipe 7 is connected to the top of the high-pressure gas storage tank 501. An electromagnetic valve 8 is arranged outside the air outlet pipe 7. By arranging the air outlet pipe 7 and the electromagnetic valve 8, it is convenient for the staff to convey high-pressure gas into the interior of the first connecting pipe 503. One end of the first connecting pipe 503 is connected to a second connecting pipe 9. By arranging the second connecting pipe 9 and the third connecting pipe 504, it is convenient for the staff to adjust the acceleration of the piston 10's movement according to multiple connecting pipes, thereby adjusting the kinetic energy carried by the piston 10. One end of the second connecting pipe 9 far from the first connecting pipe 503 is connected to one end of the third connecting pipe 504, facilitating the piston 10 to enter the interior of the third connecting pipe 504 through the first connecting pipe 503 and the second connecting pipe 9.

[0031] A piston 10 is arranged inside the second connecting pipe 9. By arranging the piston 10, under the action of the piston 10, the impact head 11 can be impacted, thereby transmitting the carried kinetic energy and making the impact head 11 move. An impact head 11 is arranged inside the third connecting pipe 504. A pressure force sensor 12 is arranged on one side of the impact head 11. By arranging the pressure force sensor 12, when the impact head 11 contacts the steel structure three-dimensional model, the pressure force sensor 12 can detect the pressure at the contact position and then transmit the data.

[0032] A first flange 13 is arranged outside the second connecting pipe 9. By arranging the first flange 13 and the second flange 14, it is convenient for the staff to connect the first connecting pipe 503 and the second connecting pipe 9 through the positioning bolt 15, thereby enabling the piston 10 to move. A second flange 14 is arranged outside the third connecting pipe 504, and a positioning bolt 15 is arranged inside the first flange 13.

[0033] Reference Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown in, a lead screw mechanism 16 is arranged inside the base 1. By arranging the lead screw mechanism 16, under the action of the lead screw mechanism 16, the position of the connecting frame 17 can be adjusted, and then the first connecting pipe 503 can be clamped and positioned. The connecting frame 17 is arranged outside the lead screw mechanism 16.

[0034] A first snap ring 18 is fixedly connected to the rear surface of the connecting frame 17. By arranging the first snap ring 18, under the action of the two first snap rings 18, the first connecting pipe 503 can be preliminarily limited. The inner ring of the first snap ring 18 is welded with a first spring 19.

[0035] One end of the first spring 19 away from the first snap ring 18 is welded with a clamping plate 20. By providing the clamping plate 20, under the elastic force of the first spring 19, the inner ring of the clamping plate 20 can be closely attached to the outer side of the first connecting pipe 503, thereby positioning the first connecting pipe 503 and preventing the first connecting pipe 503 from shaking or shifting. Both the bottom and the top of the first snap ring 18 are fixedly connected with connecting plates 21.

[0036] Bolts 22 are arranged inside the connecting plates 21. By providing the bolts 22, it is convenient for the staff to position and connect the two first snap rings 18 through the bolts 22. A second fixing rod 23 is fixedly connected inside the base 1, and a second spring 24 is sleeved outside the second fixing rod 23. By providing the second spring 24, under the elastic force of the second spring 24, the pressing plate 602 can move to a specified position, so that one side of the pressing plate 602 is closely connected to one side of the steel structure three-dimensional model, thereby positioning the steel structure three-dimensional model. The outside of the second fixing rod 23 is slidably connected with the inside of the pressing plate 602.

[0037] A top rod 25 is fixedly connected to the top of the pressing rod 604. By providing the top rod 25 and the side rod 26, when the pressing rod 604 is slid, the side rod 26 and the moving frame 27 can move, thereby adjusting the position of the second snap ring 28. The rear surface of the top rod 25 is fixedly connected with the side rod 26, and one end of the side rod 26 away from the pressing rod 604 is fixedly connected with the moving frame 27.

[0038] A second snap ring 28 is arranged on the rear surface of the moving frame 27, and a soft pad 29 is arranged on the rear surface of the second snap ring 28. By providing the second snap ring 28 and the soft pad 29, when the moving frame 27 moves to a specified position, the second snap ring 28 and the soft pad 29 can move to a specified position, thereby clamping and positioning both sides of the steel structure three-dimensional model. A placement groove 30 adapted to the first connecting pipe 503 is opened inside the insertion plate 4.

[0039] Working principle: When the staff needs to conduct a collision test on the 3D steel structure model, first, the staff pushes the pressing plate 602, causing the second spring 24 to be compressed. Then, the 3D steel structure model is placed at the specified position on the top of the base 1. After placement, by sliding the pressing rod 604, the second snap ring 28 and the soft pad 29 are used to move the second snap ring 28 to the specified position, so as to position and clamp the 3D steel structure model. After the 3D steel structure model is positioned, the staff adjusts the positions of the two first snap rings 18 through the lead screw mechanism 16. Then, the staff installs a preset number of connecting pipes through the first flange 13 and the second flange 14. After installation, the hose 502 is connected to the air outlet pipe 7, and at the same time, the first connecting pipe 503 is placed at the specified position. Under the elastic force of the first spring 19, the clamping plate 20 can move to the specified position. Thus, under the action of the two clamping plates 20, the first connecting pipe 503 is positioned and clamped. After positioning and clamping, the staff makes the solenoid valve 8 open through the PLC controller 3. Then, the high-pressure gas can enter the inside of the first connecting pipe 503 through the hose 502 and then enter the inside of the second connecting pipe 9. Under the action of the high-pressure gas, the piston 10 bears a certain impact force. Then, after the piston 10 bears a certain acceleration, it enters the inside of the third connecting pipe 504. Under the action of the piston 10, a certain impact can be applied to the impact head 11, so that the impact head 11 breaks away from the third connecting pipe 504 and impacts the 3D steel structure model. At the same time, under the action of the laser velocimeter 505, the speed of the impact head 11 is detected, and the kinetic energy carried by the impact head 11 is calculated. When the impact head 11 collides with the 3D steel structure model, the pressure force sensor 12 can detect the impact force generated between the impact head 11 and the 3D steel structure model, which is convenient for the staff to detect the collision performance of the 3D steel structure model and improve the accuracy of the collision performance detection.
