Description

Technical Field

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

[0002] In the process of road and bridge construction, road surface paving is a crucial link, and its quality directly affects the service life of roads and bridges and driving safety. Traditional road surface paving devices have many shortcomings in practical applications. Therefore, a road surface paving device for road and bridge construction that lays a smooth surface is used to level the bridge surface.

[0003] Existing technologies, such as patent CN215441462U, disclose a road and bridge pavement paving device. This patent uses a device body, on the top side of which a first motor is fixedly installed. A first pulley is movably installed on one side of the first motor, a belt is movably installed on one side of the first pulley, and a second pulley is movably connected to one side of the belt. A rotating shaft is fixedly connected to the axis of the second pulley. This utility model device solves the problem that in the use of existing equipment, after concrete or asphalt transport vehicles arrive at the paving site, they generally pour it directly into the roadbed with the side formwork installed, requiring construction personnel to level it, which is a time-consuming and laborious process.

[0004] In daily operation, workers usually need to manually place the concrete onto the road surface during the use of the equipment. Manual placement can easily lead to uneven placement, resulting in unevenness during paving. Utility Model Content

[0005] The purpose of this invention is to solve the problem of difficulty in leveling concrete road surfaces in the prior art, and to propose a road paving device for laying a smooth road and bridge construction surface.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a road surface paving device for laying a smooth road and bridge, comprising an installation frame, a connecting frame, a material frame, and a mover. The installation frame is fixedly connected to one side of the connecting frame, the material frame is fixedly connected to the side of the installation frame away from the connecting frame, the mover is disposed at the lower end of the installation frame, a diversion device is disposed on the upper surface of the connecting frame, a leveling device is disposed inside the connecting frame, the diversion device comprises a material hopper and a screw pusher, the leveling device comprises a scraper and a limiting frame, the material hopper is fixedly connected to the upper surface of the connecting frame, the screw pusher is fixedly connected to the lower side of the material hopper, the scraper is fixedly connected to the lower surface of the connecting frame, the limiting frame is fixedly connected inside the connecting frame, and an installer is fixedly connected to the upper end of the installation frame.

[0007] Furthermore, the installer is internally fixedly connected to an inlet pipe, the outlet end of which is inserted into the material hopper. By setting the installer, the inlet pipe can be positioned and fixed, reducing the likelihood of the inlet pipe shaking during equipment use, which could cause concrete to have difficulty entering the material hopper smoothly.

[0008] Furthermore, a connecting plate is fixedly connected to the end of the screw pusher away from the material hopper. The connecting plate can limit the connection between the discharge pipe and the screw pusher.

[0009] Furthermore, a discharge pipe is fixedly connected to the side of the connecting plate away from the screw pusher.

[0010] Furthermore, three cylinders are fixedly connected to the lower surfaces of both ends of the limiting frame, and a first connecting frame, a second connecting frame, and a third connecting frame are fixedly connected to the lower surfaces of the moving ends of the three cylinders, respectively. The first connecting frame is close to the discharge pipe, and the third connecting frame is close to the scraper. By setting the scraper, the uneven concrete surface can be scraped smooth.

[0011] Furthermore, the second connecting frame is disposed between the first connecting frame and the third connecting frame, and a plurality of equidistant first push blocks are fixedly connected to the lower surface of the first connecting frame. The first push blocks can be used to initially separate the accumulated concrete.

[0012] Furthermore, the lower surface of the second connecting frame is fixedly connected with a plurality of equidistant second push blocks, and the lower surface of the third connecting frame is fixedly connected with a plurality of equidistant third push blocks. By setting the second push blocks and the third push blocks, the concrete separated by the first push blocks can be further separated, and the concrete can be spread evenly on the road surface.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, a diversion device is installed. When pouring concrete onto the surface of roads and bridges, the concrete outlet pipe is connected to the installer. The concrete then enters the material hopper through the inlet pipe via the installer. When the material hopper is filled to a certain amount, the screw pusher is activated to transport the material from the hopper into the outlet pipe, thus evenly distributing the concrete onto the road surface. By setting up the diversion device, the concrete is effectively and evenly distributed onto the road surface, achieving uniform material distribution. In general equipment, workers manually distribute the concrete onto the road surface, which can easily lead to uneven distribution and uneven paving. This diversion device, through the coordinated work of the material hopper, screw pusher, installer, inlet pipe, connecting plate, and outlet pipe, achieves precise and efficient material diversion, improving the equipment's versatility and practicality.

[0014] In this invention, by setting up a leveling device, concrete is piled on the road surface. When the equipment moves slowly, the cylinder drives the first connecting frame, the second connecting frame, and the third connecting frame to move the first push block, the second push block, and the third push block downwards, maintaining a certain distance from the road surface. This allows the concrete to be distributed. Then, a scraper flattens the concrete. By setting up the leveling device, the piled concrete is effectively leveled, playing a smoothing role. In general equipment, when using it, the concrete pile needs to be manually broken up and leveled by workers. Manual leveling is prone to creating potholes. This leveling device, through components such as a scraper, a limiting frame, a cylinder, the first connecting frame, the second connecting frame, the third connecting frame, the first push block, the second push block, and the third push block, effectively achieves the leveling of road materials, ensuring the smoothness of the road surface and improving the practicality of the equipment.

[0017] Please see Figures 1-5This utility model provides a technical solution: a road surface paving device for laying a smooth road and bridge, including a mounting frame 1, a connecting frame 2, a material frame 3 and a mover 4. The mounting frame 1 is fixedly connected to one side of the connecting frame 2, the material frame 3 is fixedly connected to the side of the mounting frame 1 away from the connecting frame 2, and the mover 4 is set at the lower end of the mounting frame 1.

[0018] The following section will explain the specific setup and function of the diversion device 5 and the leveling device 6.

[0019] In this embodiment: a diversion device 5 is provided on the upper surface of the connecting frame 2, and a leveling device 6 is provided inside the connecting frame 2. The diversion device 5 includes a material hopper 51 and a screw pusher 54. The leveling device 6 includes a scraper 69 and a limiting frame 68. The material hopper 51 is fixedly connected to the upper surface of the connecting frame 2. The screw pusher 54 is fixedly connected to the lower side of the material hopper 51. The scraper 69 is fixedly connected to the lower surface of the connecting frame 2. The limiting frame 68 is fixedly connected inside the connecting frame 2. An installer 52 is fixedly connected to the upper end of the mounting frame 1.

[0020] A screw pusher 54 is a device that uses the rotation of a screw to move objects or materials. It mainly consists of a screw and a drive unit. The screw is usually cylindrical with spiral protrusions on its surface, called threads. The drive unit is generally composed of a motor, a reducer, etc. When the drive unit drives the screw to rotate, the material is extruded through the gap between the screws, thereby achieving precise pushing and transporting of the material.

[0021] Specifically, the inlet pipe 53 is fixedly connected inside the installer 52, and the outlet end of the inlet pipe 53 is inserted inside the material hopper 51.

[0022] In this embodiment, by setting the installer 52, the feed pipe 53 can be positioned and fixed, reducing the likelihood of the feed pipe 53 shaking during use, which would make it difficult for concrete to enter the material hopper 51 smoothly.

[0023] Specifically, a connecting plate 55 is fixedly connected to the end of the screw pusher 54 away from the material hopper 51. The connecting plate 55 can limit the connection between the discharge pipe 56 and the screw pusher 54.

[0024] Specifically, the side of the connecting plate 55 away from the screw pusher 54 is fixedly connected to the discharge pipe 56.

[0025] In this implementation scheme: three cylinders 67 are fixedly connected to the lower surfaces of both ends of the limiting frame 68. The lower surfaces of the moving ends of the three cylinders 67 are respectively fixedly connected to the first connecting frame 62, the second connecting frame 64 and the third connecting frame 66. The first connecting frame 62 is close to the discharge pipe 56 and the third connecting frame 66 is close to the scraper 69.

[0026] In this embodiment: by setting scraper 69, the uneven concrete surface can be scraped smooth.

[0027] Specifically, the second connecting frame 64 is set between the first connecting frame 62 and the third connecting frame 66. The lower surface of the first connecting frame 62 is fixedly connected with a plurality of equidistant first push blocks 61. The first push blocks 61 can be used to initially separate the accumulated concrete.

[0028] Specifically, the lower surface of the second connecting frame 64 is fixedly connected with a plurality of equidistant second push blocks 63, and the lower surface of the third connecting frame 66 is fixedly connected with a plurality of equidistant third push blocks 65. By setting the second push blocks 63 and the third push blocks 65, the concrete separated by the first push block 61 can be further separated, and the concrete can be spread evenly on the road surface.

[0029] Working Principle: When pouring concrete onto the surface of roads and bridges, the concrete outflow pipe is connected to the installer 52. The concrete then enters the material hopper 51 through the inlet pipe 53 via the installer 52. When the material hopper 51 is filled with a certain amount of concrete, the screw pusher 54 is activated to transport the material from the material hopper 51 into the outlet pipe 56, evenly distributing the concrete onto the road surface. By setting up the diversion device 5, the concrete is effectively and evenly distributed onto the road surface, achieving uniform material distribution. In general equipment, workers manually distribute the concrete onto the road surface, which can easily lead to uneven distribution and uneven paving. This diversion device 5, through the coordinated work of the material hopper 51, screw pusher 54, installer 52, inlet pipe 53, connecting plate 55, and outlet pipe 56, achieves precise and efficient material diversion, improving the equipment's versatility and practicality.

[0030] When concrete is piled up on the road surface, and the equipment moves slowly, cylinder 67 drives the first connecting frame 62, the second connecting frame 64, and the third connecting frame 66 to move the first push block 61, the second push block 63, and the third push block 65 downwards, maintaining a certain distance from the road surface. This allows the concrete to be distributed. Then, scraper 69 flattens the concrete. By setting up the leveling device 6, the piled concrete is effectively leveled, playing a smoothing role. In general equipment use, the concrete pile needs to be manually broken up and leveled by workers, which can easily lead to potholes. This leveling device 6, through components such as scraper 69, limit frame 68, cylinder 67, first connecting frame 62, second connecting frame 64, third connecting frame 66, first push block 61, second push block 63, and third push block 65, effectively achieves the leveling of road materials, ensuring the smoothness of the road surface and improving the practicality of the equipment.
