[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-5 The utility model provides a technical solution: a traffic engineering construction safety management anti-collision device, including a support frame 1, the bottom surface of the support frame 1 is welded and fixed to a fixed base 2, a slide groove 3 is provided on the top of the support frame 1, the slide groove 3 is a rectangular through groove, the inner wall of the slide groove 3 is welded and fixed to two symmetrical guide rods 4 at both ends, a spring 5 is sleeved on the outer side of the guide rod 4, the spring 5 is located between the slide groove 3 and the slider 6, the outer side of the guide rod 4 is slidably connected to the slider 6, the side surface of the support frame 1 is welded and fixed to the outer side of the sleeve 7, an air hole 8 is provided at the center of one end of the sleeve 7, a spring 2 9 is sleeved inside the sleeve 7, and the inner side of the sleeve 7 is provided with a spring 3. The top of the connecting rod 13 is welded and fixed to the mounting plate 15, and the mounting plate 15 is threadedly connected to the fixing bolt 16. The bottom of the fixing bolt 16 is threadedly connected to the slider 6. The outer side of the connecting rod 13 is welded and fixed to the anti-collision roller 17, and a buffer chamber 18 is arranged inside the anti-collision roller 17.
[0022] The shape of the support frame 1 is "H"-shaped, with one end of the sleeve 7 extending to one side of the support frame 1, and the air hole 8 and the push rod 10 being located on both sides of the support frame 1. One side of the sleeve 7 is slidably connected to the outside of the push rod 10 through a circular through hole, and one end of the push rod 10 extends to the inside of the sleeve 7 and is fixedly connected to the sealing piston. An energy absorption chamber is provided inside the sleeve 7, and the air hole 8 is connected to the energy absorption chamber, and the spring 2 9 is located in the energy absorption chamber. The H-shaped design makes the center of gravity of the support frame 1 more stable, thereby improving the stability of the overall device during a collision and avoiding self-fracture during a collision. The air hole 8 and the push rod 10 are located on both sides so that the push rod 10 can move inside the sleeve 7 so that the air in the energy absorption chamber converts the impact force into pressure, and the air is ejected from the air hole 8 to achieve a buffering effect;
[0023] Two symmetrical circular through holes are provided on the side of the slider 6. The slider 6 is slidably connected to the outer side of the guide rod 4 through the circular through holes. Threaded holes are provided at the center of the slider 6 and at the top of the mounting plate 15. The slider 6 is connected to the mounting plate 15 through the fixing bolts 16. The fixing block 11 is inserted into the connecting rod 13 to fix the connecting rod 13, and then the slider 6 and the mounting plate 15 are connected through the fixing bolts 16 to complete the replacement of the anti-collision roller 17. The fixing block 11 is movably connected with the limiting groove 14. There are two T-slots 12, which are located on the upper and lower sides of the fixing block 11. A plurality of annular energy-absorbing grooves are provided on the outer side of the anti-collision roller 17. The buffer cavity 18 is located on the outer side of the anti-collision roller 17. A rubber buffer layer is provided on the inner layer of the anti-collision roller 17. The bottom of the connecting rod 13 is fixed by clamping the T-slot 12 and the limit slot 14, and the top fixing bolt 16 is further used to fix the anti-collision roller 17, so as to facilitate the subsequent replacement or repair of the anti-collision roller 17 after buffering and energy absorption. The two symmetrical connecting rods 13 and the mounting plate 15 are connected and fixed by the upper and lower symmetrical T-slots 12, which enhances the stability of the overall buffer device and improves the buffering effect by increasing the number of anti-collision rollers 17.
[0024] Working principle: When the anti-collision device collides, first the buffer groove and buffer cavity 18 on the outside of the anti-collision roller 17 are impacted and compressed, and cooperate with the rubber buffer layer inside the anti-collision roller 17 to buffer for the first time, and then the anti-collision roller 17 is forced to drive the mounting plate 15 to move, and further make the slider 6 slide on the outside of the guide rod 4 and squeeze the spring 15, and the spring 15 is used for energy absorption and buffering. The anti-collision roller 17 is forced to push the push rod 10 to move inside the sleeve 7, and the spring 2 9 is used for energy absorption and buffering. At the same time, the internal pressure of the sleeve 7 increases when it is impacted, and the air is discharged from the air hole 8, further enhancing the effect of energy absorption and buffering; when the anti-collision roller 17 needs to be replaced, the bottom of the new connecting rod 13 is placed in the T-slot 12, and the fixing block 11 is inserted into the connecting rod 13 to fix the connecting rod 13, and then the slider 6 and the mounting plate 15 are connected by the fixing bolt 16, and the replacement of the anti-collision roller 17 is completed, which effectively reduces the difficulty of repair.
