Technical Field
[0001] This utility model relates to the technical field of road construction, specifically to a road construction anti-collision roller device. Background Technology
[0002] During road construction, road rollers play a crucial role in compacting the road surface. However, existing road rollers are prone to collisions due to the complex environment of the construction site, which often includes obstacles, construction personnel, or other machinery. These collisions can damage the road rollers themselves, endanger personnel safety, and affect the construction progress. To address this, multiple rangefinders are installed on the side of the road roller to measure distances, and an alarm system is used to issue warnings.
[0003] Rangefinders may be damaged by impacts during use, and the likelihood of collision varies depending on the height at which they are used, thus requiring different protection zones. Commonly used rangefinders do not allow for adjustment of the protection zone as needed. Therefore, those skilled in the art have provided a road construction anti-collision roller device to address the aforementioned problems. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a road construction anti-collision roller device.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A road construction anti-collision roller device includes a frame. Within the frame is a moving block vertically driven by a motor and a threaded rod. A rangefinder for sensing lateral distance is mounted on the outer side of the moving block. An alarm electrically connected to the rangefinder is also mounted on the frame. Two vertical slots are parallel to each other on the rear side of the moving block, located on both sides of the threaded rod. Guide plates for guiding and limiting the moving block are vertically inserted into these slots. The thickness of the guide plates increases uniformly from the middle to the top and bottom ends on the front side. Two horizontal slots are horizontally distributed above and below the rangefinder within the moving block, communicating with the vertical slots. Protective horizontal plates are inserted into these horizontal slots. A crossbeam is fixedly installed on the rear side of the protective horizontal plate. The crossbeam is configured as follows: The structure has two symmetrically arranged fixing blocks fixedly installed on the inner walls of both sides of the transverse groove. The two parallel rods of the transverse frame pass through the two fixing blocks respectively, and the two parallel rods of the transverse frame are fitted with springs to make the transverse frame abut against the guide plate.
[0007] Preferably, the front side of the guide plate is V-shaped, and the contact surface between the crossbeam and the guide plate is arc-shaped.
[0008] Preferably, the two protective cross plates extend out of the horizontal slot by equal and minimum distances when the protective cross plates are located in the middle of the guide plate, and vertical protection plates are arranged at the edges of the extended parts of the protective cross plates.
[0009] Preferably, the vertical protection plates are arranged in one of "1", "V" or "W" shapes.
[0010] Preferably, the closest distance between the vertical protection plates on the same side is less than the overall height of the range finder.
[0011] In summary, the present application has the following beneficial technical effects:
[0012] 1. When the range finder is located in the upper part of the stroke, the upper protective cross plate extends horizontally by a greater distance than the lower protective cross plate, and when the range finder is located in the lower part of the stroke, the lower protective cross plate extends horizontally by a greater distance than the upper protective cross plate, so that the protection possibility can be adapted to different working conditions.
[0013] 2. The extended part of the protective cross plate is provided with a vertical protection plate, so that the range finder can be further protected, and the vertical impact on the protective cross plate can be supported. BRIEF DESCRIPTION OF DRAWINGS
