Description

Technical Field

[0001] The utility model relates to the technical field of bridge protection, and in particular to an assembled bridge steel structure anti-collision box. Background Art

[0002] The assembled bridge steel structure crash box is a protective facility used to protect bridges and traffic projects. The assembled bridge steel structure crash box is made of high-strength steel and is usually formed by welding. The protective box body is usually an integral structure, and can also be assembled in sections for easy transportation and on-site installation. The main function of the assembled bridge steel structure crash box is to protect bridge piers, abutments, guardrails and other structures from damage caused by vehicle collisions in traffic projects such as bridges, tunnels or roads. The crash box can effectively absorb the energy from vehicle collisions and reduce the damage caused by accidents. The connection stability between the crash box and the bridge directly affects the protective effect of the crash box on the bridge. Therefore, it is necessary to perform connection protection work between the crash box and the bridge.

The internal thread of the installation opening 3 is connected with a mounting bolt 4, and after the mounting bolt 4 installs and connects the anti-collision block 2 and the anti-collision angle 1 with the external bridge body, the mounting bolt 4 and the mounting opening 3 can be closed and sealed to reduce the erosion effect of external moisture and river water on the installation, and to avoid rusting of the mounting bolt 4 during operation, which leads to a reduction in the anti-collision effect of the anti-collision block 2 and the anti-collision angle 1 on the bridge body, thereby improving the anti-collision effect of the anti-collision block 2 and the anti-collision angle 1 on the bridge body and the installation connection stability.

A force-applying mechanism is arranged on both sides of the inner wall of the push opening 10. After the mounting bolt 4 installs and connects the anti-collision block 2 and the anti-collision angle 1 on the surface of the external bridge body through the mounting opening 3, the protective plate 5 is held and driven to drive the contact sleeve 6 to be installed into the inside of the mounting opening 3. Since the contact sleeve 6 is made of rubber material, as the protective plate 5 is installed into the inside of the mounting opening 3, the contact sleeve 6 contacts with the inner wall of the mounting opening 3 to produce deformation, which affects the protective plate 5 and the mounting The contact sealing work is performed between the openings 3, and the installation bolt 4 is installed with moisture-proof work to ensure the installation connection stability of the installation bolt 4 and the anti-collision effect of the anti-collision angle 1 and the anti-collision block 2 on the bridge body.

One end of the spring 17 is fixedly connected to the inner wall of the reset groove 15, and the other end of the spring 17 is fixedly connected to the surface of the reset plate 16. Before the tightening block 8 and the protective pad are used, the position of the tightening block 8 can be pushed and reset to avoid the position of the tightening block 8 being offset from the tightening opening 7 when in use, thereby preventing the tightening block 8 from being offset from the tightening opening 7 when in use, thereby preventing the tightening block 8 from being offset from the tightening opening 7, thereby preventing the tightening block 8 from being offset from the tightening opening 7, thereby preventing the tightening block 8 from being offset from the tightening opening 7, thereby preventing the tightening block 8 from being offset from the tightening opening 7, thereby preventing the tightening block 8 from being offset from the tightening opening 7, and ...

When the push rod 11 is used in conjunction with the force block 13, a medium for positioning the push rod 11 can be provided for the user, so as to avoid the situation that the push rod 11 is difficult to position when the push rod 11 is used in conjunction with the force block 13, thereby improving the convenience of positioning the push rod 11.

The front side of the lifting seat 25 is fixedly connected to the rear side of the lifting sleeve 22. When the lifting sleeve 22 is used in conjunction with the card strip 21, the lifting connection work can be performed between the raw sleeve, the card strip 21 and the protective plate 5 to avoid the situation where the card strip 21 is driven away from the protective plate 5 when the lifting sleeve 22 is used, thereby improving the use stability of the lifting sleeve 22. Magnetic strips 26 are inlaid on both sides of the inner wall of the lifting groove 24, and fixed blocks 27 are inlaid on both sides of the rear side of the lifting seat 25. The rear side of the fixed block 27 is magnetically connected to the front side of the magnetic strip 26. When the lifting column is used in conjunction with the lifting sleeve 22, the lifting sleeve 22 can be magnetically positioned through the lifting seat 25 to avoid the situation where the lifting sleeve 22 is difficult to position when in use, thereby improving the positioning convenience of the lifting sleeve 22.

[0038] Specifically, the working process or working principle of the assembled bridge steel structure anti-collision box is as follows: when in use, after the staff installs the anti-collision angle 1 and the anti-collision block 2 on the outside of the external bridge body through the installation bolt 4, the handheld protective plate 5 drives the contact sleeve 6 to be installed into the installation port 3. Since the contact sleeve 6 is made of rubber material, as the protective plate 5 is installed into the installation port 3, the contact sleeve 6 contacts with the inner wall of the installation port 3 to produce deformation, and the contact sealing work is performed between the protective plate 5 and the installation port 3. When installing the protective plate 5, attention should be paid to the angle of the reinforcement frame 19 and the installation port 3. The angles of the bolts 4 are consistent. During this process, the spring 17 applies an inward thrust to the force seat 14 through the reset plate 16, so that the force seat 14 contacts the force block 13 and maintains the position of the tight block 8. When the protective plate 5 is installed into the installation opening 3, the reinforcement frame 19 moves with the protective plate 5 through the reinforcement rod 18, and is stuck on the outside of the installation bolt 4 to reinforce the installation, preventing the installation bolt 4 from rotating after installation. Subsequently, the hand-held push rod 11 is pushed backward to drive the force block 13 to actually move outward through the force seat 14 to the tight block 8 The moving pressing force makes the pressing block 8 drive the anti-skid pad 9 to contact and press against the inner wall of the installation opening 3, and the protective plate 5 and the installation opening 3 are pressed and positioned. At this time, the spring 17 is affected by the moving force of the reset plate 16 and the force seat 14 in the reset groove 15 to shrink. Then, the moving handle 23 is held and applied with a downward thrust to the lifting sleeve 22, so that the lifting sleeve 22 drives the card strip 21 to enter the card groove 20 to position the push rod 11. At this time, the lifting seat 25 follows the lifting sleeve 22 to move in the lifting groove 24, and the lifting sleeve 22 and the anti-skid pad 9 are pressed and positioned. The protective plates 5 are movably connected with each other. At the same time, the fixed block 27 cooperates with the magnetic strip 26 to perform magnetic positioning on the lifting sleeve 22 and the clamping strip 21 through the lifting seat 25. The positioned push rod 11 positions the force block 13 during operation, so that the force block 13 cooperates with the force seat 14 to ensure the pressing force of the clamping block 8 and the anti-slip pad 9 on the inner wall of the installation opening 3, prompting the protective plate 5 to cooperate with the contact sleeve 6 to perform stable sealing and protection on the installation bolt 4 inside the installation opening 3, thereby ensuring the anti-collision protection effect of the anti-collision angle 1 and the anti-collision block 2 on the bridge body after installation.
