A road mileage marking device

Abstract

The utility model discloses a road mileage marking device, which belongs to the field of road engineering technology, and aims to solve the problem that most of the existing road mileage marking devices are cast with cement and have a fixed height position. When the trees and weeds on the roadside grow luxuriantly or there are other obstructions, the numerical value of the mileage mark is easily covered, and the numerical value of the mileage mark cannot be displayed intuitively. It includes a mileage marking plate, a column, and a drive assembly. The mileage marking plate is symmetrically distributed on both sides of the column. The back of the mileage marking plate is installed with a drive assembly, and the drive assembly is installed on the column. The road mileage marking device can adjust the position of the mileage marking plate. When the position of the mileage marking plate is too low and blocked, the rocker can be rotated, and the lifting tube is forced to slide up along the inside of the column. After the lifting tube moves the mileage marking plate to the required position, the rotation of the rocker can be stopped, so that the display height of the mileage marking plate is higher to avoid being blocked when it is at a low position.

Technical Field

[0001] The utility model belongs to the technical field of road engineering, and in particular relates to a road mileage marking device. Background Art

[0002] Road mileage markers refer to milestones or signs regularly set up on roads or highways to determine the distance and position of vehicles. These markers are usually in kilometers or miles and are set up on the roadside or bridges. Road mileage markers can help drivers accurately understand their positions, and also facilitate emergency rescue personnel and road maintenance personnel to locate and respond to accidents or emergencies. In the prior art, road mileage marker devices are mostly cast in cement with a fixed height. When trees and weeds grow lushly on the roadside or there are other obstructions, the mileage marker values ​​are easily covered, and the mileage marker values ​​cannot be displayed intuitively. Therefore, the inventor proposes a road mileage marker device. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] This specific implementation is a road mileage marking device, and its structural schematic diagram is shown in FIG. Figure 2 As shown, it includes a mileage marking plate 1, a column 2, and a driving component 3. The mileage marking plate 1 is symmetrically distributed on both sides of the column 2. The driving component 3 is installed on the back of the mileage marking plate 1, and the driving component 3 is installed on the column 2.

[0024] Reference Figure 3 , Figure 4The driving assembly 3 includes a lifting tube 5, a driving screw 6, and a rocker 4. The lifting tube 5 slides and penetrates along the upper surface of the column 2. The bottom of the lifting tube 5 is threadedly connected to the driving screw 6. The driving screw 6 is vertically rotated and installed inside the column 2. The back of the mileage mark plate 1 has an insert block, and the outside of the insert block is detachably sleeved with a mounting block 7. The inside of the mounting block 7 has a socket 12 adapted to the insert block. The side of the mounting block 7 away from the mileage mark plate 1 is fixedly connected to a fixed disk 10, and a connecting rod 9 is horizontally fixed between the fixed disk 10 and the lifting tube 5. A U-shaped support frame 14 is fixed on the upper surface of the mounting block 7, and the inner side of the support frame 14 is movable through a limited plug rod 13. The limited plug rod 13 is inserted along the upper surface of the mounting block 7. The upper surface of the insert block inside the mounting block 7 has a limiting hole, and the limiting plug rod 13 is adapted to be plugged in the limiting hole. The upper surface of the limiting plug rod 13 is fixedly connected to an operating rod 8, which is horizontally arranged and moves synchronously with the limiting plug rod 13. A limit strip 11 is protruded from the outer wall of the lifting tube 5, and a limit groove is provided at the opening of the upper surface of the column 2, and the limit strip 11 is slidably adapted to the limit groove. A driven bevel gear is fixedly sleeved at the bottom of the driving screw 6, and a driving bevel gear distributed vertically is provided on the side of the driven bevel gear. A rocking wheel 4 is rotatably mounted on the lower end of the side wall of the column 2, and the rocking wheel 4 is fixedly connected to the driving bevel gear and is distributed concentrically. When the rocking wheel 4 is turned, the rocking wheel 4 drives the driven bevel gear to rotate through the driving bevel gear, and the driving screw 6 connected concentrically with the driven bevel gear rotates, and then the lifting tube 5 sleeved on the outside thereof is forced to slide up along the inside of the column 2.

[0025] Working principle: When in use, a highway data mark is provided on the mileage mark plate 1. When the position of the mileage mark plate 1 is too low and blocked, the rocker 4 can be rotated. The rocker 4 drives the driven bevel gear to rotate by driving the bevel gear, and the driving screw 6 connected to the driven bevel gear cocentrically rotates, and then the lifting tube 5 sleeved on the outside is forced to slide up along the inside of the column 2. The lifting tube 5 has a limit strip 11 on the outer wall. When the limit strip 11 slides along the column 2, it can ensure that the lifting tube 5 is not driven by external force and maintains stable vertical sliding. After the lifting tube 5 moves the mileage mark plate 1 to the required position, the rotation of the rocker 4 can be stopped, so that the display height of the mileage mark plate 1 is higher to avoid being blocked when it is at a low place. If it is blocked at a high place, the adjusting wheel is rotated in the opposite direction to lower the height of the mileage mark plate 1.

[0026] When the mileage marking plate 1 needs to be replaced or its surface cleaned, the mileage marking plate 1 can be disassembled, and the operating rod 8 is pulled up, and the operating rod 8 drives the limiting plug rod 13 to slide up from the support frame 14, and the bottom of the limiting plug rod 13 is also moved out of the mounting block 7, and then the plug block inside the mileage marking plate 1 is separated from the limiting plug rod 13, and it can be removed from the mounting block 7 for subsequent operations. The principle is simple and easy to implement, and can be widely promoted.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
