Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to a road leveling device. Background Technology

[0002] The construction of various public infrastructure facilities that support urban life falls under the category of municipal engineering, such as common urban roads, bridges, and subways. In the process of paving municipal roads, leveling devices are needed to level the roads.

[0003] In the process of road construction, general leveling devices simply use leveling rollers to level the road by rolling. In actual operation, manual labor is required to initially level the cement so that the leveling device can level it later. Otherwise, the leveling device needs to work back and forth many times, which increases the workload and reduces construction efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a road leveling device to overcome the shortcomings of the above-mentioned technology.

[0005] To achieve the above objectives, this utility model provides a road leveling device, including a frame, a leveling roller, and a front roller. A carrier plate is connected to the frame via a connecting column, and a bearing seat is provided on the carrier plate. A rotating shaft is provided on the bearing seat, and the rotating shaft is fixedly connected to the rear side of the leveling roller. The frame has four connecting rods, arranged in pairs on the upper and left sides of the leveling roller, respectively. An auxiliary roller is provided on each connecting rod, fitting against the surface of the leveling roller. A column is provided on the front side of the leveling roller. The frame has two supporting slide rails, each slidably connected to a connecting column via a slider. A U-shaped frame is fixedly connected to the bottom of the two connecting columns, and two opposing supporting bearings are provided on the U-shaped frame. Connecting shafts are provided at the front and rear of the front roller. The connecting shafts correspond one-to-one with the supporting bearings. A connecting plate is provided on each connecting column, and a through-channel with an arc shape is provided on the connecting plate. The column can slide within the through-channel. A push rod is provided on the left side of the frame.

[0006] Preferably, the number of bearing housings is at least two.

[0007] Preferably, the outer end of the column is provided with a limiting circular plate.

[0008] Preferably, the frame is provided with support wheels, and the wheel surface of the support wheels is provided with annular grooves.

[0009] Preferably, the frame is provided with a scraper, which is set to fit against the surface of the leveling roller.

[0010] Preferably, the scraper is disposed on the lower side of the auxiliary roller located to the left of the leveling roller.

[0011] The beneficial effects of this utility model are as follows: the push rod drives the frame to move forward, and the front roller and leveling roller press the road a second time to complete the road leveling operation; when the leveling roller rotates forward, the column will rotate around the center of the front side of the leveling roller as the origin. During the rotation of the column, due to the existence of the arc-shaped through channel, it will drive the connecting plate to make reciprocating linear motion, that is, it will drive the connecting column two to make reciprocating linear motion, so that the front roller also makes reciprocating motion when it follows the leveling roller as a whole, thus performing preliminary leveling of the cement and effectively improving the effect of preliminary leveling of the road surface. In conjunction with the leveling roller, it can further improve the leveling effect of the road surface. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0020] Reference Figure 1-5 This embodiment provides a road leveling device, including a frame 1, a leveling roller 2, and a front roller 3. The frame 1 is connected to a carrier plate 5 via a connecting column 4. The carrier plate 5 has a bearing seat 6, and a rotating shaft 7 is mounted on the bearing seat 6. The rotating shaft 7 is fixedly connected to the rear side of the leveling roller 2. The frame 1 has four connecting rods 8, arranged in pairs on the upper and left sides of the leveling roller 2. The connecting rods 8 have auxiliary rollers 9, which are fitted against the surface of the leveling roller 2. Because the leveling roller 2 is only connected to the rotating shaft 7 on one side, the connecting column 4 experiences significant lateral pressure, making it prone to damage. The auxiliary rollers 9 distribute the pressure on the connecting column 4, reducing its stress. The front side of the leveling roller 2 has a column 10 located at the outer periphery of the center of the front side. The frame 1 has two supporting slide rails 11, each with a slider 1. 2. Two sliding connecting columns 13 are fixedly connected to the bottom of two connecting columns 13. Two opposing support bearings 15 are provided on the U-shaped frame 14. Connecting shafts 16 are provided on the front and rear of the front roller. The connecting shafts 16 and the support bearings 15 are arranged in a one-to-one correspondence. A connecting plate 17 is provided on the connecting column 13. A through channel 18 is provided on the connecting plate 17. The through channel 18 is arc-shaped. The circumference of the outer arc of the through channel 18 is smaller than the circumference of the semicircle at the same center. The column 10 can slide in the through channel 18. The column 10 abuts against the inner wall of the through channel 18. When the column 10 rotates with the leveling roller 2, the column abuts against the inner wall of the through channel, driving the connecting plate to move reciprocally laterally and driving the connecting column 13 to move reciprocally linearly. The linkage structure of the connecting plate 17 is different from the crankshaft linkage. There is no torsional force between the connecting plate 17 and the connecting column 13. A push rod 19 is provided on the left side of the frame 1.

[0021] The number of bearing seats 6 is at least two, which increases the rotational stability of the leveling roller 2.

[0022] The outer end of the column 10 is provided with a limiting circular plate 20 to limit the movement direction of the connecting plate 17 and prevent the connecting plate 17 from shaking.

[0023] The frame 1 is equipped with a support wheel 21, and the wheel surface of the support wheel 21 is provided with an annular groove 22. When the support wheel 21 is placed on the baffles on both sides of the cement to be leveled, the annular groove 22 abuts against the upper surface of the baffle, which can ensure the overall balance of the device and ensure that the bottom surfaces of the leveling roller 2 and the front roller 3 are on the same horizontal plane, thus ensuring the leveling effect of the cement. The bottom surface of the annular groove 22 is on the same horizontal plane as the bottom surfaces of the leveling roller 2 and the front roller 3.

[0024] The frame 1 is equipped with a scraper 23, which is set to fit against the surface of the leveling roller 2. The scraper 23 is located on the lower side of the auxiliary roller 9 on the left side of the leveling roller 2. During the forward movement of the leveling roller 2, some cement will adhere to it. The scraper can scrape off the adhered cement to prevent cement from entering the auxiliary roller 9 and causing the auxiliary roller 9 to be unable to rotate.

[0025] When this utility model is in use, the push rod 19 drives the frame 1 to move forward, and the front roller 3 and the leveling roller 2 press the road a second time to complete the road leveling operation. When the leveling roller 2 rotates forward, the column 10 will rotate around the center of the front side of the leveling roller 2. During the rotation of the column 10, due to the existence of the arc-shaped through channel 18, it will drive the connecting plate 17 to make reciprocating linear motion, which will drive the connecting column 13 to make reciprocating linear motion. This makes the front roller 3 also make reciprocating motion when it follows the leveling roller 2 forward, which will initially level the cement and effectively improve the effect of initial leveling of the road surface. In conjunction with the leveling roller 2, it can further improve the leveling effect of the road surface.

[0026] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model.
