Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a road paving device for road construction. Background Technology

[0002] With the continuous development of technology, the application of concrete in road construction is increasing. The conventional operation procedure for road paving is to first pour permeable concrete, which has been mixed in a specific ratio, into a pre-built road mold, and then use a paving device to level the road surface.

[0003] Traditional road paving methods mostly involve manually smoothing concrete using a screed. However, manual operation makes it difficult to ensure the flatness of the concrete surface, easily resulting in unevenness, which affects the quality of the road. Moreover, the paving efficiency is slow. Therefore, we propose a road paving device for road construction. Utility Model Content

[0004] This invention solves the problem that manual operation makes it difficult to ensure the flatness of the concrete surface, which easily leads to unevenness, affecting the quality of the road, and the paving efficiency is slow. Therefore, it provides a road paving device for road construction.

[0005] This utility model is achieved using the following technical solution: a road paving device for road construction, comprising a fixed top plate, support frames fixedly connected to the four bottom corners of the fixed top plate, casters fixedly connected to the bottom of the support frames, a handle fixedly connected to the right end of the fixed top plate, a hydraulic rod fixedly connected to the top of the fixed top plate, the output end of the hydraulic rod penetrating the fixed top plate and fixedly connected to an mounting plate, a scraper plate fixedly connected to the bottom of the mounting plate, and a paving component provided at the bottom of the mounting plate;

[0006] The leveling assembly includes a fixing plate, and a fixing rod is rotatably connected to the inner wall of the fixing plate. There are two fixing rods, and a flattening roller is fixedly connected to the surface of each of the two fixing rods. A sprocket is fixedly connected to one end of each of the two fixing rods, and a chain is engaged with the inner wall of the sprocket. A drive motor is fixedly connected to one end of each fixing rod.

[0007] The above technical solution uses a support frame to support the fixed top plate, casters to facilitate overall movement, and a drive motor to rotate one of the fixed rods, which in turn rotates the sprocket, which in turn rotates the chain, which in turn rotates the other sprocket, causing the two flattening rollers to rotate. The flattening rollers flatten the concrete, ensuring a high degree of flatness after paving, greatly improving the efficiency of road paving and thus enhancing its practicality.

[0008] As a further improvement to the above solution, the top of the fixing plate is fixedly connected to the bottom of the mounting plate, and a motor base is fixedly connected to the front end of the mounting plate.

[0009] The above technical solution uses two fixing plates, which increases the stability of the support for the fixing rod.

[0010] As a further improvement to the above solution, the inner wall of the motor base is fixedly connected to the front end of the drive motor.

[0011] The above technical solution ensures the stability of the drive motor during use by installing and fixing it with a motor mount.

[0012] As a further improvement to the above solution, the flattening roller is located at the left end of the scraper plate, and two baffle plates are fixedly connected to the right end of the scraper plate.

[0013] The above technical solution uses baffles to shield both sides of the scraper plate, preventing excess concrete from being squeezed onto both sides of the scraper plate and affecting the chain and sprocket in the paving assembly.

[0014] As a further improvement to the above solution, a limit rod is slidably connected to the inner wall of the fixed top plate.

[0015] The above technical solution uses a limiting rod to limit the mounting plate, preventing it from shifting during movement and ensuring stability during use.

[0016] As a further improvement to the above solution, the bottom of the limiting rod is fixedly connected to the top of the mounting plate.

[0017] The above technical solution ensures the structural stability of the mounting plate by fixing it to the limiting rod.

[0018] As a further improvement to the above solution, two limiting rods are provided, and the two limiting rods are symmetrically distributed with the mounting plate as the center.

[0019] The above technical solution improves the limiting effect of the mounting plate by using two limiting rods.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] (1) This utility model sets up a paving component, specifically by scraping the concrete with a scraper plate to remove excess concrete, and then by driving one of the fixed rods to rotate through the output end of the drive motor, causing the sprocket to rotate, which in turn drives the chain to rotate, thereby driving the other sprocket to rotate, causing the two pressing rollers to rotate, and pressing the concrete to flatten it, ensuring that the flatness of the paved concrete is high, which greatly improves the efficiency of road paving and thus improves its practicality.

[0022] (2) By setting up a hydraulic rod and a limiting rod, the present invention pushes the mounting plate downward through the output end of the hydraulic rod, so that the scraper plate contacts the concrete. At the same time, the leveling component also moves downward, which makes it easy to adjust the height of the scraper plate and the leveling component according to the needs, thus improving the flexibility of use.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0031] Please combine Figure 1-5This embodiment of a road paving device for road construction includes a fixed top plate 1, a support frame 2 fixedly connected to the four bottom corners of the fixed top plate 1, a caster wheel 3 fixedly connected to the bottom of the support frame 2, a handle 4 fixedly connected to the right end of the fixed top plate 1, a hydraulic rod 5 fixedly connected to the top of the fixed top plate 1, the output end of the hydraulic rod 5 passing through the fixed top plate 1 and fixedly connected to a mounting plate 6, a scraper plate 7 fixedly connected to the bottom of the mounting plate 6, and a paving component 8 provided at the bottom of the mounting plate 6.

[0032] The paving assembly 8 includes a fixing plate 801, with two fixing rods 802 rotatably connected to the inner wall of the fixing plate 801. Each fixing rod 802 has a flattening roller 803 fixedly connected to its surface, and a sprocket 804 fixedly connected to one end of each fixing rod 802. A chain 805 meshes with the inner wall of the sprocket 804. A drive motor 806 is fixedly connected to one end of each fixing rod 802. When the drive motor 806 is started, its output drives one of the fixing rods 802 to rotate, causing the sprocket 804 to rotate, which in turn drives the chain 805 to rotate, thus driving the other sprocket 804 to rotate. This causes the two flattening rollers 803 to rotate, flattening the concrete and ensuring a high degree of flatness after paving. This significantly improves the efficiency of road paving and enhances its practicality.

[0033] The top of the fixing plate 801 is fixedly connected to the bottom of the mounting plate 6, and the front end of the mounting plate 6 is fixedly connected to the motor base 9.

[0034] The inner wall of the motor base 9 is fixedly connected to the front end of the drive motor 806. The drive motor 806 is fixed by the motor base 9, which ensures the stability of the drive motor 806 during use.

[0035] The flattening roller 803 is located at the left end of the scraper plate 7. Two baffle plates 10 are fixedly connected to the right end of the scraper plate 7. The device can be moved by pulling the handle 4. The scraper plate 7 is used to initially flatten the concrete and remove excess concrete. The baffle plates 10 cover the sides of the scraper plate 7 to prevent excess concrete from being squeezed to the sides of the scraper plate 7 and wasted.

[0036] A limit rod 11 is slidably connected to the inner wall of the fixed top plate 1.

[0037] The bottom of the limiting rod 11 is fixedly connected to the top of the mounting plate 6. When the mounting plate 6 moves, it is limited by the limiting rod 11, so that the mounting plate 6 maintains linear movement.

[0038] There are two limit rods 11, which are symmetrically distributed around the mounting plate 6.

[0039] The implementation principle of a road paving device for road construction in this application embodiment is as follows: when in use, the hydraulic rod 5 is activated, and the mounting plate 6 is pushed downward through the output end of the hydraulic rod 5, so that the scraper plate 7 comes into contact with the concrete. At the same time, the paving component 8 also moves downward, which makes it easy to adjust the height of the scraper plate 7 and the paving component 8 according to the needs, thus improving the flexibility of use.

[0040] Then, by pulling handle 4, the entire device is moved, and the concrete is initially leveled by scraper plate 7 to remove excess concrete. The sides of scraper plate 7 are blocked by baffle plate 10 to prevent excess concrete from being squeezed to the sides of scraper plate 7 and wasted.

[0041] When the drive motor 806 is started, its output drives one of the fixed rods 802 to rotate, which in turn drives the sprocket 804 to rotate, which in turn drives the chain 805 to rotate, which in turn drives the other sprocket 804 to rotate, causing the two flattening rollers 803 to rotate. The flattening rollers 803 flatten the concrete, ensuring a high degree of flatness after paving, which greatly improves the efficiency of road paving and thus enhances its practicality.

[0042] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
