Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides an embodiment: a combined bridge anti-collision fence comprises an anti-collision fence body 1 and a support frame 2, wherein the support frame 2 is fixedly arranged at the bottom end of the anti-collision fence body 1, a first guardrail 15 is inserted into the left side of the anti-collision fence body 1, a second guardrail 16 is fixedly connected to the right side of the first guardrail 15, a convenient and fast dismounting device is arranged at the bottom end of the anti-collision fence body 1 and comprises a fixed seat 3, a first slide rail 4, a handle 12, a second slide rail 13, a gear 17 and a second groove 18, the second slide rails 13 are arranged into two groups, the two groups of second slide rails 13 are perpendicular to an anti-collision base 20, the cross section of each second slide rail 13 is of a rectangular structure, the second slide rails 13 and the first slide rails 4 form a sliding structure, the first guardrail 15 and the second guardrail 16 are more easily mounted on the inner side of the anti-collision fence body 1 through sliding, compared with the traditional welding installation, the anti-collision fence is, and second recess 18 and gear 17 constitute the slip over-and-under type structure, when needing to change or maintenance second guardrail 16 and gear 17, can let second guardrail 16 and gear 17 roll off the anticollision barrier body 1 inboard through rotating gear 17, have promoted the convenience that the device dismantled to a great extent.

The safety performance improving device is arranged on the back side of the anti-collision fence body 1 and comprises contact blocks 5, first reset springs 6, a first groove 7, a supporting block 8, second reset springs 9, clamping blocks 10, anti-collision columns 11, a handle 12, connecting columns 14 and sleeves 19, the contact blocks 5 are arranged into three groups, the three groups of contact blocks 5 are perpendicular to a first guardrail 15, so that the force borne by the front surfaces of a second guardrail 16 and a gear 17 can be uniformly reduced, the anti-collision columns 11 are arranged into three groups, the three groups of anti-collision columns 11 are perpendicular to an anti-collision base 20, the anti-collision columns 11 are of cylindrical structures, the anti-collision columns 11 are made of hard metal, so that impact on the side surfaces can be resisted, further movement of an out-of-control vehicle is prevented, danger is caused, the connecting columns 14 are of rectangular structures, the connecting columns 14 and the sleeves 19 form a rotary structure, when the front surfaces, the sliding between the connecting column 14 and the sleeve 19 allows a certain degree of force to be removed and a large portion of the impact force to be transferred to the second rail 16 and the two sides of the gear 17 and partially offset by the elastic force of the contact block 5, thus improving the safety of the device.

The working principle is as follows: according to the attached drawing 1, when the anti-collision fence body 1 is fixed during installation, the second guardrail 16 slides into the inner side of the anti-collision fence body 1 along the first slide rail 4, then the first guardrail 15 slides into the inner side of the anti-collision fence body 1 along the first slide rail 4, the sleeve 19 is sleeved into the inner side of the connecting column 14, meanwhile, the first guardrail 15 and the second guardrail 16 are ensured to be positioned on the same horizontal plane, when the anti-collision fence is disassembled, the handle 12 is rotated, the gear 17 and the second groove 18 are meshed with each other, so that the second groove 18 can drive the second guardrail 16 to upwards rise along with the rotation of the gear 17, and meanwhile, the first guardrail 15 connected with the second guardrail 16 also upwards rises.

According to the attached drawing 2, when the crash barrier body 1 is impacted by the side, the right side of the crash barrier body 1 is damaged, so that the bottom end of the right side of the support frame 2 is not clamped with the clamping block 10 any more, under the elastic force of the second return spring 9, the crash barrier column 11 can be lifted upwards to prevent the out-of-control vehicle from continuing to go forward and further causing danger, according to the attached drawing 1, when the out-of-control vehicle collides with the front surface of the crash barrier body 1, the connecting column 14 and the sleeve 19 are clamped with each other, so that the connecting column 14 and the sleeve 19 can rotate to a certain extent, when the connecting column 14 and the sleeve 19 rotate, a certain angle is formed between the front surfaces of the first guardrail 15 and the second guardrail 16, when the surface is impacted, the out-of-control vehicle can be blocked to a certain extent to unload force, and when the unload force to a certain extent is carried out, a large part of the impact force is transferred to the two sides of the, according to fig. 3, since the contact block 5 is perpendicular to the first and

second guardrails

15 and 16, the impact force transmitted between the first and

second guardrails

15 and 16 is partially offset by the elastic force of the first return spring 6, thereby greatly improving the safety of the device.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
