Description

Technical Field

[0001] This utility model relates to the field of municipal construction technology, and more specifically, to a height restriction device for municipal construction. Background Technology

[0002] Municipal infrastructure refers to structures built to allow roads to cross natural or man-made obstacles. These structures are built over rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly. Municipal infrastructure generally consists of a superstructure, a substructure, and ancillary structures.

[0003] Municipal infrastructure is now ubiquitous and plays a vital role. Height restrictions are necessary during municipal construction to prevent vehicles exceeding the height limit from passing through the area, thus avoiding damage to the road surface caused by overloaded vehicles, such as cracks and subsidence. However, adjusting the height of existing height restriction devices for municipal construction is cumbersome. If operators climb the pillars to manually adjust the height, it is not only time-consuming and laborious, but also unsafe, resulting in poor work efficiency. Furthermore, some vehicles that are too tall and collide with the height restriction board will also cause damage to the vehicle, making its protective function inadequate. Therefore, we propose a height restriction device for municipal construction. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a height restriction device for municipal construction that overcomes or at least partially solves the above technical problems.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] Please see Figure 1-5This utility model provides a technical solution: a height restriction device for municipal construction, including a fixed base 101, a fixed frame 102 fixedly installed on the top of the fixed base 101, a scale 103 provided on one side of the fixed frame 102 for easy monitoring of the height restriction plate 106, a horizontal plate 104 fixedly installed on the top of the fixed frame 102, a lighting lamp 105 fixedly installed at the bottom of the horizontal plate 104, and a lifting mechanism 200 installed inside the fixed frame 102 for easy adjustment of the height restriction plate 106. The lifting mechanism 200 is attached to a height restriction plate 106 on one side. A warning plate 107 is fixedly installed on the top of the height restriction plate 106. A shock-absorbing mechanism 300 is fixedly installed on one side of the height restriction plate 106. The shock-absorbing mechanism 300 can protect the height restriction plate 106 when the protective plate 108 is impacted. A protective plate 108 is fixedly installed on one side of the shock-absorbing mechanism 300. A reflective strip 109 is fixedly installed on one side of the protective plate 108. The lighting 105 and the reflective strip 109 work together to remind the driver at night and prevent the driver from being distracted.

[0026] The lifting mechanism 200 includes a groove 201, which is located on one side of the fixed frame 102. A screw 202 is rotatably mounted inside the groove 201. A threaded block 203 is threaded onto the outer wall of the screw 202. A fixed block is fixedly mounted on one side of the threaded block 203. A slot is provided inside the fixed block, and a height limiting plate 106 is engaged in the slot. One end of the screw 202 passes through the fixed frame 102 and the horizontal plate 104 and is fixedly connected to a servo motor 204. The servo motor 204 can drive the screw 202 to rotate, thereby controlling the lifting and lowering of the threaded block 203. This controls the raising and lowering of the height restriction plate 106. A protective box 205 is fixedly installed on the outer wall of the servo motor 204. The protective box 205 is fixedly installed on the top of the horizontal plate 104. A solar panel 206 is fixedly installed on the top of the horizontal plate 104. The solar panel 206 can absorb sunlight and convert it into electrical energy to provide power for the servo motor 204 and the lighting lamp 105. A mounting groove 207 is opened at the bottom of the horizontal plate 104. A storage battery 208 is embedded in the mounting groove 207. The storage battery 208 is electrically connected to the servo motor 204 and the lighting lamp 105 respectively.

[0027] The shock absorption mechanism 300 includes a fixed sleeve 301, a cavity 302 inside the fixed sleeve 301, a groove 303 on the inner wall of the cavity 302, a slider 304 slidably installed inside the groove 303, a slide plate 305 fixedly installed on one side of the slider 304, a spring 306 fixedly installed on one side of the slide plate 305, the end of the spring 306 away from the slide plate 305 fixedly installed on the inner wall of the cavity 302, and a sliding sleeve 307 fixedly installed on the other side of the slide plate 305, the end of the sliding sleeve 307 away from the slide plate 305 fixedly connected to the protective plate 108. Through the cooperation of the groove 303, the slider 304, and the spring 306, the shock absorption function can be achieved.

[0028] Specifically, the working process or principle of a height restriction device for municipal construction is as follows: During use, the solar panel 206 absorbs sunlight and converts it into electrical energy, which is stored in the battery 208. The battery 208 provides power to the servo motor 204 and the lighting 105. The user can start the servo motor 204, which drives the screw 202 to rotate, thereby controlling the threaded block 203 to rise and fall. During the rising and falling process, the threaded block 203 drives the height restriction plate 106 to rise and fall. During the rising and falling of the height restriction plate 106, the user can adjust the scale... 103 is used to observe and control the height of the height restriction plate 106. When the height restriction plate 106 is raised or lowered to a certain height, the user turns off the servo motor 204. When driving at night, the lighting 105 can be turned on to remind the driver of the presence of the height restriction plate 106 and prevent the driver from being distracted. When the vehicle height is higher than the height restriction plate 106, the vehicle will hit the protective plate 108 due to the driver's mistake. The protective plate 108 will control the sliding sleeve 307 to press the sliding plate 305, thereby squeezing the spring 306, which can play a certain protective role for the height restriction plate 106.

[0029] It should be noted that the lighting lamp 105, servo motor 204, solar panel 206 and battery 208 are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
