Description

Technical Field

[0001] This utility model relates to highway safety facilities, and in particular to a highway speed bump that is easy to replace. Background Technology

[0002] In certain special road sections, such as entrances to schools and hospitals, as well as sections passing through villages, toll stations, and continuous curves or downhill sections, mandatory speed bumps are installed to maximize the safety of motor vehicles and pedestrians. The purpose is to force drivers to slow down so that vehicles can pass safely. After long-term use, speed bumps may become damaged due to various reasons and need to be replaced. Currently, replaceable speed bumps are available, such as the patent titled "Speed ​​Bump with Partial Replacement Function" (publication number CN 219808292 U) and the patent titled "Speed ​​Bump for Traffic Construction that is Easy to Disassemble and Replace" (publication number CN 212983655 U). These include an internal metal mounting base and an external rubber speed block. To enable the rubber speed block to be detachably connected to the metal mounting base, a groove with edges is cut on the inner side of the rubber speed block. A protrusion matching the groove is provided on the outside of the metal mounting base. When the metal mounting base and the rubber-metal block are used together, the rubber speed block is more easily damaged by the protrusion under the pressure of vehicles. Utility Model Content

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0021] like Figure 1As shown, a replaceable highway speed bump includes a metal mounting base 1, multiple rubber speed bumps 2, and two metal limiting blocks 3. The metal mounting base 1 is fixed to the road surface. The multiple rubber speed bumps 2 are covered on the surface of the metal mounting base 1 along the length direction of the metal mounting base 1. The two metal limiting blocks 3 are respectively set at both ends of the metal mounting base 1 to prevent the rubber speed bumps 2 from detaching from the metal mounting base 1.

[0022] The metal mounting base 1 includes a long strip mounting plate 4, which is embedded in the road surface. Multiple countersunk holes 5 are provided on both sides of the long strip mounting plate 4. The long strip mounting plate 4 is connected to the road surface by expansion bolts passing through the countersunk holes 5 on both sides. A support body 5 is provided in the middle of the width direction of the mounting plate 4. In cross-section, the support body 5 is trapezoidal, wider at the bottom and narrower at the top. The support body 5 supports the middle of an arc-shaped support plate 6. There are gaps between the sides of the arc-shaped support plate 6 and the sides of the mounting plate 4. Slots 7 are provided on both sides of the arc-shaped support plate 6 and the sides of the support body 5. The slots 7 are arc-shaped, and their curvature and orientation are consistent with the curvature and orientation of the arc-shaped support plate 6. The mounting plate 4, the support body 5, and the arc-shaped support plate 6 are integrally formed.

[0023] The rubber speed reducer 2 includes an arc segment 8, with both sides of the arc segment 8 folded inward to form an insertion segment 9. The arc segment 8 of the rubber speed reducer 2 is attached to the arc support plate 6, and the insertion segments 9 on both sides are slidably located in the slots 7 on both sides of the metal fixing seat 1. The connection position between the arc segment 8 and the insertion segment 9 of the rubber speed reducer 2 is located on the fixing plate 4, and the arc segment 8 and the two insertion segments 9 are integrally formed.

[0024] The metal limiting block 3 is semi-circular, and the semi-circular metal limiting block 3 is connected to the end face of the metal fixing seat 1 by screws.

[0025] When installing the speed bump, first pour the fixing plate 4 into the road surface and drive expansion bolts into the countersunk holes on both sides of the fixing plate 4. Then, insert the two insertion sections 9 of a rubber speed bump 2 into the two slots 7 from the end of the metal fixing base 1. Then slide the rubber speed bump 2 and install the next rubber speed bump 2 in the same way until all the rubber speed bump 2 are installed on the metal fixing base 1. After installation, install the two metal limiting blocks 3 at both ends of the metal fixing base 1 with screws. After the speed bump has been used for a period of time, some of the rubber speed bump 2 will be damaged. Then, open the metal limiting block 3 closest to the damaged rubber speed bump 2, and then remove the rubber speed bump 2 one by one until the damaged rubber speed bump 2 is removed. Then replace it with a new rubber speed bump 2, install the other rubber speed bump 2, and fix the metal limiting block 3.

[0026] The use of this speed bump can reduce maintenance costs. The mating surface between the rubber speed bump 2 and the metal fixing seat 3 is an arc surface, so the rubber speed bump 2 is not easily damaged by the reaction force of the metal fixing seat 3 when it is run over by a vehicle.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
