Description

Technical Field

[0001] This utility model belongs to the field of bridge engineering technology, and in particular relates to a novel anti-collision guardrail telescopic device. Background Technology

[0002] According to the published patent CN220550448U, a novel anti-collision guardrail telescopic device includes: a first steel cover plate, a second steel cover plate, a steel pad plate, a third steel cover plate, a fourth steel cover plate, and a telescopic sealing strip. The first steel cover plate and the steel pad plate are respectively fixed to the impact surfaces of the first and second wall-type guardrails. Anchor bolt holes and transverse elongated holes are respectively provided on the left and right sides of the second steel cover plate, with one side fixedly connected to the steel pad plate and the second wall-type guardrail. This anti-collision guardrail telescopic device, installed on the anti-collision guardrail, is stable, reliable, and not easily damaged, and can better resist damage caused by rain and snow in northern regions. It also meets the requirements for bridge expansion and contraction displacement. However, it still has the following shortcomings: While the aforementioned equipment can install guardrails on wall-mounted railings, its simple structure and the fact that it often requires additional tools for installation make the process cumbersome and inconvenient for users. Therefore, we propose a new type of anti-collision guardrail telescopic device. Utility Model Content

[0003] The purpose of this utility model is to provide a new type of anti-collision guardrail telescopic device. Through the installation mechanism and the protective mechanism, it solves the problem that although the above-mentioned equipment can install the guardrail on the wall-type guardrail, the structure of the device is relatively simple and often requires other tools to install it on the wall-type guardrail, making the installation method cumbersome and inconvenient for users.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a novel anti-collision guardrail telescopic device, including several wall-type guardrails and metal cover plates. The outer walls of the several wall-type guardrails are slidably connected with mounting plates, the inner walls of the several wall-type guardrails are provided with mounting holes, and the outer walls of the wall-type guardrails are provided with mounting mechanisms. The installation mechanism includes several bidirectional threaded rods, each with a number of annular limiting blocks threaded to its outer wall. Each annular limiting block has a limiting shaft rotatably connected to its inner wall. A connecting rod is fixedly connected to the outer wall of the limiting shaft. A second limiting shaft is fixedly connected to the inner wall of the connecting rod away from the limiting shaft. A clamping plate is rotatably connected to the outer wall of the second limiting shaft. Several limiting blocks are fixedly connected to the outer wall of the mounting plate near the clamping plate. Several positioning holes are formed on the inner wall of the mounting plate near the limiting blocks. Insert rods are slidably connected to the inner walls of the positioning holes. Several springs are fixedly connected to the outer wall of the insert rods. A protective mechanism is provided on the outer wall of the wall-type guardrail.

[0005] Furthermore, the outer wall of the bidirectional threaded rod is rotatably connected to the inner wall of the mounting plate, the outer wall of the insert rod is slidably connected to the inner wall of the bidirectional threaded rod, and the outer walls of the plurality of springs are all fixedly connected to the outer wall of the bidirectional threaded rod.

[0006] Furthermore, the protective mechanism includes a plurality of dampers, the outer walls of which are fixedly connected to the outer wall of the mounting plate, and the outer walls of which are fixedly connected to the outer wall of the metal cover plate.

[0007] Furthermore, a plurality of damping springs are fixedly connected to the outer wall of the mounting plate near the damper, and the outer walls of the plurality of damping springs are all fixedly connected to the outer wall of the metal cover plate. A plurality of slide rails are fixedly connected to the outer wall of the mounting plate near the damping springs.

[0008] Furthermore, a plurality of slide rods are fixedly connected to the inner wall of the slide rail, and sliders are slidably connected to the outer wall of the slide rods.

[0009] Furthermore, a plurality of damping springs are fixedly connected to the outer wall of one end of the slider near the slide rod, and the outer walls of the plurality of damping springs are all fixedly connected to the inner wall of the slide rail, and the inner walls of the plurality of sliders are rotatably connected to limit shafts.

[0010] Furthermore, a connecting plate is fixedly connected to the outer wall of the slider, and a limiting shaft four is fixedly connected to the inner wall of the end of the connecting plate away from the limiting shaft three.

[0011] Furthermore, a fixing block is fixedly connected to the outer wall of the limiting shaft four, and the outer walls of several fixing blocks are fixedly connected to the outer wall of the metal cover plate.

[0012] This utility model has the following beneficial effects: 1. This utility model features a connecting rod on a limiting shaft. When the device is needed, the rod is pulled outward from the joint between the wall-mounted guardrail and the metal cover plate using a tool. Pulling the rod outward compresses multiple springs. When the rod is completely pulled out of the positioning hole, a slight rotation of the rod is sufficient. The rotation of the rod drives the bidirectional threaded rod to rotate, which in turn drives multiple annular limiting blocks to move towards the center. This allows users to easily install the metal cover plate directly onto the guardrail. The installation method is simple and convenient, improving user efficiency and facilitating subsequent disassembly for replacement or maintenance.

[0013] 2. This utility model, by setting a slider on the sliding rod, allows the metal cover plate to be compressed towards the wall-type guardrail when the equipment is in use. This is because multiple metal cover plates are interlocked. As the metal cover plate moves, it compresses multiple dampers and damping springs. At the same time, the movement of the metal cover plate drives the fourth limiting shaft to move towards the wall-type guardrail. The movement of the fourth limiting shaft drives the connecting plate to move the third limiting shaft. This achieves a certain shock absorption and protection effect on the metal cover plate when it is impacted by the vehicle, extending the service life of the metal cover plate, reducing the damage caused by the vehicle, and improving the safety of the device.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-7 As shown, this utility model is a novel anti-collision guardrail telescopic device, including several wall-type guardrails 1 and metal cover plates 101. The outer walls of the several wall-type guardrails 1 are slidably connected with mounting plates 102, and the inner walls of the several wall-type guardrails 1 are provided with mounting holes 103. The outer walls of the wall-type guardrails 1 are provided with mounting mechanisms 2. Through the mounting holes 103, it is convenient for users to directly install the mounting plates 102 into the wall-type guardrails 1. The mounting mechanism 2 includes several bidirectional threaded rods 201. Each bidirectional threaded rod 201 has a number of annular limiting blocks 202 threaded to its outer wall. Each annular limiting block 202 has a limiting shaft 203 rotatably connected to its inner wall. A connecting rod 204 is fixedly connected to the outer wall of the limiting shaft 203. The limiting shaft 203 can restrict the position of the connecting rod 204, allowing it to rotate only on the limiting shaft 203, and also preventing the connecting rod 204 from falling off. A second limiting shaft 205 is fixedly connected to the inner wall of the end of the connecting rod 204 away from the limiting shaft 203. A clamping plate 206 is rotatably connected to the outer wall of the second limiting shaft 205. The mounting plate 102 is close to the clamping plate 206. Several limiting blocks 207 are fixedly connected to the outer wall of one end of the 06. The movement trajectory of the clamp 206 can be limited by the limiting blocks 207, so that it can only move in a straight line along the direction of the limiting blocks 207. Several positioning holes 208 are opened on the inner wall of the mounting plate 102 near the limiting blocks 207. Insert rods 209 are slidably connected to the inner walls of the positioning holes 208. Several springs 210 are fixedly connected to the outer wall of the insert rods 209. The outer wall of the wall-type guardrail 1 is provided with a protective mechanism 3. Through the springs 210, the springs 210 can always squeeze the insert rods 209 to insert them into the positioning holes 208 through their own elastic force.

[0020] The outer wall of the bidirectional threaded rod 201 is rotatably connected to the inner wall of the mounting plate 102, the outer wall of the insertion rod 209 is slidably connected to the inner wall of the bidirectional threaded rod 201, and the outer walls of several springs 210 are fixedly connected to the outer wall of the bidirectional threaded rod 201. The protective mechanism 3 includes several dampers 301, which can limit the movement trajectory of the damping springs 302 to prevent the dampers 301 from breaking during extension and retraction. The outer walls of several dampers 301 are fixedly connected to the outer wall of the mounting plate 102 and the outer wall of the metal cover plate 101. The outer wall of the mounting plate 102 is located near one end of the damper 301. Several damping springs 302 are fixedly connected. The damping springs 302 will always compress the metal cover plate 101 through their own elastic force, thereby playing a certain role in shock absorption and protection of the metal cover plate 101. The outer walls of the damping springs 302 are fixedly connected to the outer wall of the metal cover plate 101. Several slide rails 303 are fixedly connected to the outer wall of the mounting plate 102 near the damping springs 302. Several slide rods 304 are fixedly connected to the inner wall of the slide rails 303. Through the slide rods 304, the movement trajectory of the slider 305 can be limited, so that the slider 305 can only slide in a straight line along the direction of the slide rod 304.

[0021] A slider 305 is slidably connected to the outer wall of the slide rod 304. Several damping springs 306 are fixedly connected to the outer wall of the slider 305 near the slide rod 304. The outer walls of the damping springs 306 are all fixedly connected to the inner wall of the slide rail 303. A limiting shaft 307 is rotatably connected to the inner wall of each slider 305. The limiting shaft 307 can limit the position of the connecting plate 308, ensuring it can only rotate on the limiting shaft 307, and simultaneously preventing the connecting plate 308 from moving. To prevent detachment, a connecting plate 308 is fixedly connected to the outer wall of the slider 305. A limiting shaft 309 is fixedly connected to the inner wall of the end of the connecting plate 308 away from the limiting shaft 307. A fixing block 310 is fixedly connected to the outer wall of the limiting shaft 309. The outer walls of several fixing blocks 310 are fixedly connected to the outer wall of the metal cover plate 101. The position of the limiting shaft 309 can be limited by the fixing blocks 310, and the fixing blocks 310 can prevent the limiting shaft 309 from detaching.

[0022] One specific application of this embodiment is: When staff need to use the equipment, and if the metal cover 101 becomes damaged after prolonged use, the insertion rod 209 can be pulled outward from the joint between the wall-mounted guardrail 1 and the metal cover 101 using a tool. Pulling the insertion rod 209 outward compresses multiple springs 210. When the insertion rod 209 is completely pulled out of the positioning hole 208, it can be slightly rotated. The rotation of the insertion rod 209 will drive the bidirectional threaded rod 201 to rotate, which in turn will simultaneously drive multiple rings... The annular limiting block 202 moves towards the center. When the annular limiting block 202 moves, it drives the limiting shaft 203 to move. When the limiting shaft 203 moves, it pulls the connecting rod 204 to move, causing the second limiting shaft 205 to move. The movement of the second limiting shaft 205 causes the clamping plate 206 to slide within the limiting block 207. When the clamping plate 206 moves a certain distance towards the bidirectional threaded rod 201, since the clamping plate 206 is no longer tightly attached to the inner wall of the mounting hole 103, the mounting plate 102 can be pulled outward to cover the metal cover. When the entire plate 101 is removed, during normal installation and use of the metal cover plate 101, if a vehicle impacts the outer surface of the metal cover plate 101, due to the interlocking of multiple metal cover plates 101, the metal cover plate 101 will be compressed and move towards the wall-type guardrail 1. As the metal cover plate 101 moves, it will simultaneously compress multiple dampers 301 and damping springs 302. Simultaneously, the movement of the metal cover plate 101 will drive the limiting shaft 309 to move closer to the wall-type guardrail 1. When the time is right, the connecting plate 308 will move, causing the limiting shaft 307 to move. The movement of the limiting shaft 307 will cause the slider 305 to slide towards the center on the sliding rod 304. During the sliding process, the slider 305 will simultaneously compress multiple damping springs 306, causing them to contract. At this time, the damping springs 306 and 302 will automatically reset through their own elastic force, which will play a certain role in shock absorption and protection of the metal cover 101, extend the service life of the metal cover 101, and reduce the damage caused by the vehicle.
