Detailed Embodiment

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0029] Such as Figures 1-5As shown in the figure, a large-span steel structure box girder integrated anti-collision wall includes an anti-collision wall 1, and a maintenance mechanism 2 is arranged on the outer side of the anti-collision wall 1; it also includes: The maintenance mechanism 2 includes a connection frame 201. A chute 203 is opened on one side of the surface of the connection frame 201. A sliding plate 204 is slidably connected inside the chute 203. A plurality of tracing grooves 205 are opened on the surface of the sliding plate 204; Among them, both sides of the outer wall of the sliding plate 204 are bolted with fastening bolts 206. The middle of the fastening bolts 206 is connected through the chute 203, and the end of the fastening bolts 206 abuts against the surface of the connection frame 201; Among them, one end of the bottom surface of the connection frame 201 is fixedly installed with a ladder 215. A plurality of anti-slip sleeves 216 are fixedly connected in the middle of the ladder 215. Each anti-slip sleeve 216 is arranged at equal intervals along the length direction of the ladder 215. Hanging ears 217 are symmetrically fixedly connected to the upper end of the surface of the ladder 215, as Figure 4 shown, the tracing grooves 205 on the surface of the sliding plate 204 can be opened according to the texture of the reflective paint;

[0030] The anti-collision wall 1 includes a wall body 101. A guide rail 102 is inlaid and connected in the middle of the top surface of the wall body 101. The guide rail 102 extends along the length direction of the top surface of the wall body 101 as a whole. The bottom surface of the connection frame 201 is also fixedly connected with a guide block 207. A guide wheel 208 is rotatably connected to the bottom of the guide block 207. Clamping wheels 202 are rotatably connected to both the bottom of the connection frame 201 and near the ladder 215 and the chute 203. The two clamping wheels 202 are respectively movably connected to the upper ends of both sides of the wall body 101. The surface of the guide block 207 is slidably connected to the side of the inner wall of the guide rail 102. The surface of the guide wheel 208 is slidably connected to the bottom of the inner wall of the guide rail 102, as Figure 1 shown, the clamping wheels 202 abut against both sides of the wall body 101 to prevent the maintenance mechanism 2 from tipping over to both sides as a whole due to the center of gravity shifting;

[0031] A support plate 213 is rotatably connected to the lower end of the connection frame 201 on the side away from the chute 203. A slot 214 is opened on the top surface of the support plate 213. A limiting plate 212 is fixedly connected to the outer wall of the connection frame 201 and near the support plate 213. The surface of the limiting plate 212 abuts against the side of the support plate 213, as Figures 1-2 shown, the limiting plate 212 limits the maximum flipping angle of the support plate 213. When the support plate 213 flips and falls on the surface of the limiting plate 212, the whole support plate 213 is parallel to the ground;

[0032] A plug rod 210 is connected through the top of the connection frame 201. A spring 211 is fixedly connected to the middle surface of the plug rod 210. The other side of the spring 211 is fixedly connected to the connection frame 201. Both ends of the outer wall of the plug rod 210 extend upward, and both ends of the outer wall of the plug rod 210 are connected through the connection frame 201. One end of the top of the plug rod 210 is fixedly connected to a pressing plate 209, and the other end of the top of the plug rod 210 is inserted into the inner side of the slot 214. As Figures 2-3 shown, the spring 211 pushes the end of the plug rod 210 into the inside of the slot 214, thereby locking the flipping of the support plate 213.

[0033] The working principle of the present utility model:

[0034] By pushing the connection frame 201, the guide block 207 and the guide wheel 208 move along the guide rail 102 on the top of the wall 101, thereby driving the sliding plate 204 on the side of the connection frame 201 to align with the paint repair point on the inner side of the wall 101. When drawing the reflective paint pattern of the wall 101, the operator can apply the paint along the groove 205.

[0035] Secondly, when the outer side of the wall 101 needs to be repaired, press down the pressing plate 209 to separate the plug rod 210 from the slot 214, and then push the support plate 213 to flip it towards the limiting plate 212. After the support plate 213 falls on the surface of the limiting plate 212 by gravity, the unfolding is completed. At this time, the operator can connect the safety rope to himself and the hanging ear, and then step on the surface of the support plate 213 through the ladder 215. When inspecting the outer side of the wall 101, push the wall 101 to drive the inspection mechanism 2 and itself to move along the guide rail 102, thereby facilitating the gradual inspection and repair of the outer side of the wall 101.
