Embodiment 1

[0023] see Figure 1~2 , in an embodiment of the present invention, a highway bridge engineering safety management anti-collision device, comprising two symmetrically arranged stands 1 and a square frame 2 fixed between the two stand 1; the square frame 2 is provided with A plurality of anti-collision plates 5, wherein one end of the anti-collision plate 5 is rotatably connected to the lower part of the square frame 2, and the other end is engaged in the card slot 21 provided on the upper part of the square frame 2, and the inner surface of the square frame 2 is close to the card slot. A baffle 4 is provided at the position of the slot 21; the baffle 4 is semicircular and connected to the square frame 2 through a rotating shaft 41. During normal use, the peripheral surface of the baffle 4 rotates to the bottom, so that the anti-collision plate 5 Blocking is carried out to maintain the closed state of the overall device, and when it is necessary to pass, the peripheral surface ...

Embodiment 2

[0028] see Figure 3-5 , the embodiment of the present invention expands the function on the basis of embodiment 1, specifically:

[0029] The anti-collision plate 5 includes a main body plate 51 and connecting seats 52 symmetrically arranged on the upper and lower sides of the main body plate 51, wherein the side of the connecting seat 52 close to the main body plate 51 is fixed with two fixed plates 53 arranged at intervals. A guide rod 55 is connected between the two fixed plates 53, and a guide block 54 is fixed on one side of the main body plate 51 close to the connecting seat 52, and the guide rod 55 slides through the guide block 54, between the guide block 54 and the fixed plate 53 on one side. A cushioning spring 56 is connected between them, and the cushioning spring 56 is sleeved on the periphery of the rod body of the guide rod 55, so that the impact can be effectively buffered.

[0030] Further, the damping spring 56 is a steel spring.

[0031] The bottom of the...

Abstract

The invention discloses an expressway bridge engineering safety management anti-collision device. The expressway bridge engineering safety management anti-collision device comprises two symmetrically-arranged vertical frames and a square frame fixed between the two vertical frames. A plurality of anti-collision plates are arranged in the square frame, one end of one anti-collision plate is rotationally connected to the lower portion of the square frame, the other end of the anti-collision plate is clamped in a clamping groove formed in the upper portion of the square frame, and a baffle is arranged at the position, close to the clamping groove, of the inner side face of the square frame. And the baffle is semicircular and is rotationally connected with the square frame through a rotating shaft. By arranging the multiple anti-collision plates, one end of one anti-collision plate is rotationally connected to the square frame, the other end of the anti-collision plate is subjected to rotation limitation of the anti-collision plate through the baffle, the anti-collision plate can be unfolded and folded by operating the baffle in the using process, and therefore the whole device does not need to be moved when passing is needed, and the problems in the prior art are solved.

Description

technical field [0001] The invention relates to the field of highway and bridge construction, in particular to an anti-collision device for highway and bridge engineering safety management. Background technique [0002] Highway and bridge engineering includes the bridge main body (namely the bridge superstructure and bridge substructure) engineering and the auxiliary engineering facilities in the overall bridge position. There are many affiliated engineering facilities, such as revetment, diversion embankment and other structures to regulate water flow in order to maintain the stability of the bridge at the river channel, approach bridges connecting the bridge head with the road, railings on the bridge surface to prevent wheel collisions, and sidewalks to ensure the safety of pedestrians Railings, as well as signs on the bridge, navigation signs under the bridge and bridge deck lighting equipment. [0003] Anti-collision devices are a kind of safety protection equipment in ...
