Description

Technical Field

[0001] This utility model relates to the field of speed bump technology, specifically a speed bump for municipal engineering. Background Technology

[0002] Speed ​​bumps, also known as speed ridges, are traffic facilities installed on highways to slow down passing vehicles. They are generally strip-shaped, but some are dot-shaped; the material is primarily rubber, but metal can also be used; they are typically yellow and black striped to attract visual attention, and they slightly bulge the road surface to achieve the purpose of slowing down vehicles. They are generally installed at highway intersections, industrial and mining enterprises, school entrances, residential area entrances, and other sections of road where vehicles need to slow down and where traffic accidents are prone to occur. They are a new type of traffic safety device used to reduce the speed of motor vehicles and non-motor vehicles.

[0003] To improve construction safety in municipal engineering projects, speed bumps are often installed on nearby roads to prevent traffic accidents. A search revealed a patent document with publication number CN221094904U that discloses a speed bump for municipal engineering, comprising several speed bump connecting blocks. Each connecting block is connected to the road surface via an installation mechanism. The connecting blocks are arranged in a line, and a plug-in assembly is provided between adjacent connecting blocks. This assembly includes a transverse groove on one side of the connecting block, with a plug slidably connected inside the groove. This invention utilizes the fact that the speed bump is composed of several connecting blocks. When a connecting block is damaged, the damaged portion can be replaced individually, reducing operating costs. Furthermore, by using a clamping block, plug, slot, and elastic mechanism, when a part of the speed bump is damaged, the restriction between the damaged connecting block and adjacent connecting blocks can be released, allowing the damaged connecting block to be removed and replaced with a new one. The operation is simple.

[0004] However, the speed bump in this utility model has four fixing bolts at the four corners that are fixed to the ground. When removing a single speed bump, multiple bolts need to be removed, which is inefficient and labor-intensive. Moreover, fixing with multiple bolts will cause large-area damage to the road surface and affect the road surface quality. Therefore, a speed bump for municipal engineering is proposed to solve the problems mentioned above. Utility Model Content

Every two speed bumps 3 contact each other during installation. The top of the mounting base 1 has multiple arranged threaded holes 4. The top of each speed bump 3 has a first fixing hole 5. A fixing screw 6, threaded into the threaded hole 4, is movably installed inside the first fixing hole 5. The top of the mounting base 1 on both sides is inserted with an end plate 7 located on the top of the mounting base 1. The top of the end plate 7 and the fixing plate 2 are both opened with two corresponding second fixing holes 8. Expansion bolts 9 are movably installed inside the second fixing holes 8. The mounting base 1 is placed on the road surface, fixing holes are drilled in the road surface, and the mounting base 1 and the end plate 7 are fixed to the road surface by passing the expansion bolts 9 through the second fixing holes 8. Then, multiple speed bumps 3 are aligned with the fixing threaded holes 4 and inserted into the top of the mounting base 1. When it is necessary to remove and replace the damaged speed bump 3, the corresponding fixing screws 6 are loosened and the speed bump 3 is pulled up to remove it, which is highly efficient for maintenance.

[0018] In this embodiment, the mounting base 1 has first movable grooves 10 on both the front and rear sides, and slots 11 are provided on both the front and rear inner walls of the speed bump 3. Limiting strips 12 that are inserted into the slots 11 are slidably installed on the inner sides of the first movable grooves 10 on both sides. Second movable grooves 13 that communicate with the first movable grooves 10 are provided on both the left and right ends of the mounting base 1. Connecting plates 14 extending into the second movable grooves 13 are fixedly installed on both the left and right ends of the two limiting strips 12. When installing the speed bump 3, the limiting strips 12 retract into the first movable grooves 10. After the speed bump 3 is fixed, the limiting strips 12 are pushed into the slots 11 by moving the connecting plates 14 on both sides, which further fixes the front and rear ends of the speed bump 3 and improves the stability of the speed bump 3 during installation.

[0019] The second movable groove 13 on both the left and right sides is provided with a drive mechanism 15. The right drive mechanism 15 includes a cam block 151, which is located between and in contact with the connecting plates 14 on the front and rear sides. A knob 152 is rotatably mounted on the top of the mounting base 1, extending into the second movable groove 13 and fixedly connected to the top of the cam block 151. Tension springs 153 are fixedly installed between the connecting plates 14 on the front and rear sides and the inner sidewall of the second movable groove 13. Under the action of the tension springs 153, the two ends of the cam block 151 contact the connecting plates 14, which can simultaneously move the connecting plates 14 on the front and rear sides synchronously. By rotating the knob 152, the limiting strips 12 on both sides can extend or retract in the first movable groove 10, improving the ease of operation.

[0020] The top of the left and right end plates 7 is provided with a groove 16 extending to the top of the mounting base 1. The knob 152 is located inside the groove 16. A first cover plate 17 is rotatably installed between the front and rear walls of the inner side of the groove 16.

A second cover plate 18 is rotatably installed on the top of the speed bump 3, located at the top of the first fixing hole 5. The top of the second cover plate 18 is flush with the top of the speed bump 3. The setting of the second cover plate 18 can prevent mud and sand from entering the first fixing hole 5 and affecting the subsequent removal of the fixing screws 6.

[0021] In this embodiment, reflective paper 19 is pasted on one side of the speed bump 3. The reflective paper 19 is arranged in an alternating manner on the outer side of multiple speed bumps 3. The arrangement of the reflective paper 19 makes it easier for vehicles to identify the speed bump 3 at night, thereby improving safety.

[0022] The working principle of the above embodiments is as follows: During installation, the mounting base 1 is placed on the road surface, and fixing holes are drilled in the road surface. The mounting base 1, along with the end plate 7, is fixed to the road surface by passing expansion bolts 9 through the second fixing holes 8. Then, multiple speed bumps 3 are aligned with the fixing threaded holes 4 and inserted into the top of the mounting base 1. The multiple speed bumps 3 are arranged in a row and fixed by fixing screws 6. Rotating the knob 152 causes the cam block 151 to rotate, moving the connecting plates 14 on both sides away, pushing the limit strip 12 into the slot 11 inside the speed bump 3, further fixing the speed bump 3. When it is necessary to remove and replace a damaged speed bump 3, loosen the corresponding fixing screws 6, rotate the knobs 152 at both ends, and the limit strip 12 will reset under the action of the tension spring 153. Pulling up the speed bump 3 can then remove it. Repeating the above operation allows for quick installation and high maintenance efficiency. The four expansion bolts 9 can minimize damage to the road surface.
