Description

Technical Field

[0001] The utility model belongs to the technical field of highway bridge piers, and in particular relates to a novel highway bridge pier anti-collision device. Background Art

[0002] Since the piers of highway overpasses are usually located in the middle and on both sides of the highway, it is very easy to cause accidents where vehicles collide with the piers, resulting in serious economic losses and casualties, and also seriously affecting the safety of the bridge. Therefore, the safety design of overpass piers has received more and more attention.

[0003] In a Chinese patent with publication number CN209292873U, a new type of highway pier anti-collision device is mentioned, which is used for cylindrical highway piers, and includes an outer shell, a filling material layer and an energy dissipation buffer layer. The filling material layer is arranged in a ring and coated on the outside of the highway pier, and the energy dissipation buffer layer is arranged between the filling material layer and the highway pier, and the outer shell is coated on the outside of the filling material layer; the filling material layer includes a vertically arranged honeycomb sandwich panel, and the cross-section of the honeycomb sandwich panel is a honeycomb grid composed of a number of triangles, rhombuses and regular hexagonal grids, and the honeycomb grid is filled with fillers. The new type of highway pier anti-collision device described in the utility model can effectively alleviate the impact force, ensure vehicle safety, reduce damage to the piers, and reduce losses;

[0004] Compared with the above documents, although the impact force is effectively alleviated in the above documents, the vehicle safety is ensured, the damage to the bridge piers is reduced, and the losses are minimized, when some heavy vehicles accidentally collide with the bridge piers, the impact force is too large, which can easily cause the bridge piers to tilt. The above documents only set a mechanism to reduce the impact force on the outer wall of the pier, and do not set a supporting device on the outer wall of the pier, which correspondingly increases the risk of pier collapse, thereby reducing the use effect and service life of the pier. For this reason, a new type of highway pier anti-collision device is proposed. Utility Model Content

[0024] like Figure 1-4As shown, a novel highway bridge pier anti-collision device comprises: a support mechanism, which is used to support the outer wall of the bridge pier obliquely, and the support mechanism comprises a support plate 1 and a support bottom plate 101, and the top two sides of the support bottom plate 101 are fixedly connected with fixed plates 103, and a rotating rod 104 is rotatably connected between the two fixed plates 103, and one end of the rotating rod 104 is rotatably extended to the outside of the fixed plate 103, and a plug-in rod 102 is arranged on the support bottom plate 101, and the rotating rod 104 is located on the outer wall of the fixed plate 103 and is fixedly connected with a fixed disk 105, and the fixed disk 105 is threadedly connected with a fixing bolt 106;

[0025] The utility model further specifically describes that the support plate 1 is fixedly connected to the outer wall of the rotating rod 104, and the support plate 1 is located between the two fixed plates 103, and corresponding threaded holes are opened on the fixed plate 105 and the fixed plate 103, and the fixing bolts 106 are threadedly connected to the fixed plate 105 through the threaded holes, and the fixing bolts 106 fix the fixed plate 105 and the fixed plate 103 through the threaded holes;

[0026] like Figure 1-4 As shown, a protective mechanism is installed to protect the outer wall of the pier. The protective mechanism is located on the supporting mechanism. The protective mechanism includes a connecting plate 2 and a plug-in plate 201 connected to the end of the supporting plate 1. One end of the plug-in plate 201 is fixedly connected to a protective plate 202. The inner wall of the protective plate 202 is provided with a shock-absorbing pad. A sliding plug rod 203 is slidably connected to the top of the outer wall of the connecting plate 2. Tension springs 204 are fixedly connected to the outer walls of the sliding plug rod 203. A protective shell 205 is fixedly connected to the top of the sliding plug rod 203. A limited sliding groove is provided on the plug-in plate 201. A socket is provided inside the limited sliding groove. A mounting magnetic block 207 is fixedly connected inside the socket. A sliding magnetic block 206 is fixedly connected to the bottom end of the sliding plug rod 203.

[0027] The utility model further specifically describes that a plug-in slot is provided on one side of the connecting plate 2, the plug-in plate 201 and the plug-in slot are slidingly arranged, the sliding rod 203 is located at one end of the sliding magnetic block 206 and slides to extend into the inside of the plug-in slot, the outer wall of the sliding rod 203 and the inner wall of the limiting sliding slot are slidingly fitted, the sliding rod 203 and the socket are correspondingly slidingly arranged, the sliding magnetic block 206 and the mounting magnetic block 207 are correspondingly arranged with opposite poles attracting each other, the end of the tension spring 204 away from the sliding rod 203 is connected to the connecting plate 2, and the tension spring 204 and the sliding rod 203 are both located inside the protective shell 205;

[0028] As can be seen from the above, when the staff is protecting the outer wall of the pier, they fit the shock-absorbing pad on the inner wall of the protective plate 202 with the outer wall of the pier, and then use the support plate 1 to tilt and support the outer wall of the pier. Through the action of the plug-in rod 102, the support base plate 101 can be fixed to the ground around the pier, so that the protective plate 202 is stably fitted to the outer wall of the pier, and the support plate 1 stably supports the outer wall of the pier. Through the setting of this structure, the outer wall of the pier can be installed and protected by using the shock-absorbing pad on the inner wall of the protective plate 202, which reduces the impact force of the vehicle on the pier in the event of an accident, improves the use effect and service life of the pier, and uses the support plate 1 to tilt and support the outer wall of the pier, which reduces the risk of collapse of the pier after the impact, thereby further improving the use effect and service life of the pier.

[0029] When the device is transported, the support plate 1 and the protective plate 202 are separately arranged. The support plate 1 can be rotated and stored according to the function of the rotating rod 104, so that it can be placed in a horizontal state, which is convenient for the staff to transport the support plate 1 and the protective plate 202.

[0030] When installing the protective plate 202, the plug-in board 201 on one side of the protective plate 202 is inserted into the plug-in slot on the connecting plate 2, and the limiting sliding slot and the sliding plug rod 203 slide correspondingly. When the sliding plug rod 203 corresponds to the socket, the sliding plug rod 203 is automatically inserted into the inside of the socket according to the attraction between the opposite poles of the sliding magnetic block 206 and the installation magnetic block 207, so that the plug-in board 201 and the connecting plate 2 are plugged and fixed. When removing the plug-in board 201, the protective shell 205 is pulled to correspondingly drive the sliding plug rod 203 to be detached from the socket. The plug board 201 can be removed, and then the protective plate 202 can be disassembled and replaced. Through the setting of this structure, the sliding plug rod 203 automatically inserts into the inside of the socket, which simplifies the connection operation between the plug board 201 and the connecting plate 2, and correspondingly facilitates the staff to connect and fix the protective plate 202 to the connecting plate 2. On the one hand, it is convenient for the staff to transport and carry the support plate 1 and the protective plate 202 separately, and on the other hand, the protective plate 202 can be disassembled at will, which is convenient for the staff to disassemble and replace the protective plate 202 when it is damaged;

[0031] It should be noted that one side of the protective shell 205 is not in contact with the top of the connecting plate 2 in the initial state, and is only in contact with the top of the connecting plate 2 when the sliding rod 203 is inserted into the inside of the socket, so that the sliding rod 203 and the tension spring 204 are stably protected inside the protective shell 205, thereby improving the use effect of both, and the force of attraction between the opposite poles of the sliding magnet 206 and the mounting magnet 207 is greater than the elastic expansion and contraction force of the tension spring 204.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
