Description

Technical Field

[0001] This utility model relates to the field of road construction equipment technology, and more specifically to a concrete paver. Background Technology

[0002] Three-roller pavers are commonly used construction machinery in the construction of highways, urban roads, airport runways, squares and other projects. Their function is to spread the mixed concrete evenly on the predetermined position and to perform preliminary compaction and leveling. The working process is as follows: first, side molds are set on both sides of the road surface, and then the three rollers rotate, allowing the paver to walk on the side molds, thereby completing the leveling operation of the concrete.

[0003] In practice, to ensure that the concrete between the two side molds is leveled, the two ends of the roller extend to the outside of the side molds. However, when the paver moves, concrete tends to accumulate at the ends of the roller. As the concrete is squeezed, it falls outside the side molds, which means that during construction, special personnel need to be assigned to clean the concrete outside the side molds with tools such as shovels and brooms. Removing and transporting this concrete is time-consuming and labor-intensive, and it also adds extra work steps and labor costs. Moreover, the concrete accumulated outside the side molds will stick to the side molds after it solidifies, increasing the difficulty of removing the side molds. If it is forcibly removed, it will not only damage the side molds and affect their reuse, but also damage the edges of the already paved road surface. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a concrete paver to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a concrete paver, including a three-roller paver body, a toothed column fixedly connected inside the three-roller paver body, a positioning component installed on the outer surface of the toothed column, a sliding plate fixedly connected to the bottom of the positioning component, a first guide plate hinged to the surface of the sliding plate, a second guide plate hinged to the surface of the first guide plate, a through groove through the center of the surface of the sliding plate, and ball bearings equidistantly installed inside the sliding plate;

[0006] The positioning component includes a fixing block sleeved on the outer surface of the toothed column. A sliding hole is opened through the surface of the fixing block. Steel balls are equidistantly installed inside the fixing block. A sliding column is slidably connected inside the fixing block. A toothed plate is fixedly connected to the top of the sliding column. A limit groove and a fixing plate are opened on the surface of the sliding column. A groove is fixedly connected to the inner wall of the fixing block. A spring is fixedly installed on the surface of the groove. A first bolt is threaded inside the fixing block.

[0007] Furthermore, the first guide plate has a sealing cavity inside, and a rubber sealing plate is slidably connected inside the sealing cavity. A turntable is rotatably connected inside the rubber sealing plate, and a second bolt is fixedly connected to the surface of the turntable. A nut is threaded onto the outer surface of the second bolt. Two sealing grooves are opened inside the first guide plate, and a sealing block is slidably connected inside the sealing groove. A stop bar is fixedly connected to the surface of the sealing block. The inside of the sealing groove is connected to the inside of the sealing cavity.

[0008] Furthermore, the rotating rollers on the main body of the three-roller paver are inserted into the inside of the groove, and the surface of the ball bearings is rolledly connected to the outer surface of the rotating roller.

[0009] Furthermore, the outer surface of the toothed column is inserted into the interior of the sliding hole, the surface of the steel ball is rolledly connected to the surface of the steel ball, and the surface of the toothed plate is meshed with the bottom of the toothed column.

[0010] Furthermore, the limiting groove is trapezoidal, the end face of the first bolt is arc-shaped, and the end face of the first bolt abuts against the inner wall of the limiting groove. Under normal conditions, the sliding column slides away from the sliding hole due to the elasticity of the spring.

[0011] Furthermore, there are two abutments, with the end faces of the two abutments abutting against the surfaces of the sliding plate and the second guide plate, respectively. The interior of the sealing groove is under high pressure, and the outer surface of the nut is fixedly connected to the interior of the first guide plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by setting a positioning component, allows the sliding plate, the first guide plate, and the second guide plate to slide, so that the surface of the sliding plate can fit against the outside of the side formwork. During construction, the sliding plate, the first guide plate, and the second guide plate prevent excess concrete from falling outside the side formwork, eliminating the need for dedicated personnel to clean the concrete outside the side formwork, saving labor costs and cleaning time. Construction personnel can devote more energy to other key construction stages, reducing the number of interruptions in the construction process, ensuring the continuity of the construction process, and thus accelerating the construction progress. At the same time, it also prevents concrete from falling outside the side formwork and becoming waste, so that every batch of concrete can be effectively utilized, reducing concrete waste. In large-scale engineering construction, it can save considerable material procurement costs for the project.

[0014] 2. This utility model, by setting a hinged structure between the sliding plate, the first guide plate and the second guide plate, and with the abutment of the abutment, allows the sliding plate, the first guide plate and the second guide plate to rotate relative to each other. When the side mold is in a bent state, the ball bearing, the first guide plate and the second guide plate can approach the side mold, reducing the gap between the sliding plate, the first guide plate and the second guide plate and the side mold, avoiding a large amount of concrete overflow, and enhancing adaptability.

[0022] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0023] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-6 The present invention will be further described below.

[0024] Specifically, a concrete paver includes a three-roller paver body 1, a toothed column 2 is fixedly connected inside the three-roller paver body 1, a positioning component 3 is installed on the outer surface of the toothed column 2, a sliding plate 4 is fixedly connected to the bottom of the positioning component 3, a first guide plate 7 is hinged to the surface of the sliding plate 4, a second guide plate 8 is hinged to the surface of the first guide plate 7, a through groove 5 is opened through the center of the surface of the sliding plate 4, and ball bearings 6 are equidistantly installed inside the sliding plate 4.

[0025] The positioning component 3 includes a fixing block 31 sleeved on the outer surface of the toothed column 2. A sliding hole 32 is opened through the surface of the fixing block 31. Steel balls 33 are equidistantly installed inside the fixing block 31. A sliding column 35 is slidably connected inside the fixing block 31. A toothed plate 34 is fixedly connected to the top of the sliding column 35. A limit groove 36 and a fixing plate 38 are opened on the surface of the sliding column 35. A groove 37 is fixedly connected to the inner wall of the fixing block 31. A spring 39 is fixedly installed on the surface of the groove 37. A first bolt 310 is threaded inside the fixing block 31.

[0026] In this implementation scheme, by setting the positioning component 3, the positions of the sliding plate 4, the first guide plate 7, and the second guide plate 8 can be slid, allowing the surface of the sliding plate 4 to fit against the outside of the side formwork. During construction, the sliding plate 4, the first guide plate 7, and the second guide plate 8 prevent excess concrete from falling outside the side formwork, eliminating the need for dedicated personnel to clean the concrete outside the side formwork, saving labor costs and cleaning time. Construction personnel can then devote more energy to other key construction stages, reducing the number of interruptions in the construction process, ensuring the continuity of the construction process, and thus accelerating the construction progress. At the same time, it also prevents concrete from falling outside the side formwork and becoming waste, ensuring that every unit of concrete is effectively utilized and reducing concrete waste. In large-scale engineering construction, this can save considerable material procurement costs for the project.

[0027] Specifically, the first guide plate 7 has a sealing cavity 71 inside, a rubber sealing plate 72 is slidably connected inside the sealing cavity 71, a turntable 73 is rotatably connected inside the rubber sealing plate 72, a second bolt 74 is fixedly connected to the surface of the turntable 73, a nut 75 is threadedly connected to the outer surface of the second bolt 74, two sealing grooves 76 are opened inside the first guide plate 7, a sealing block 77 is slidably connected inside the sealing groove 76, a stop bar 78 is fixedly connected to the surface of the sealing block 77, and the interior of the sealing groove 76 is connected to the interior of the sealing cavity 71.

[0028] In this embodiment, by setting a hinge structure between the sliding plate 4, the first guide plate 7, and the second guide plate 8, and with the abutment of the abutment rod 78, the sliding plate 4, the first guide plate 7, and the second guide plate 8 can rotate relative to each other. When the side mold is in a bent state, the sliding plate 4, the first guide plate 7, and the second guide plate 8 can approach the side mold, reducing the gap between the sliding plate 4, the first guide plate 7, and the second guide plate 8 and the side mold, avoiding a large amount of concrete overflow, and enhancing adaptability.

[0029] Specifically, the rotating roller on the main body 1 of the three-roller paver is inserted into the inside of the groove 5, and the surface of the ball bearing 6 is rolled and connected to the outer surface of the rotating roller.

[0030] In this embodiment, the stability of the sliding plate 4 can be improved by setting the ball bearing 6, without interfering with the rotation of the roller.

[0031] Specifically, the outer surface of the toothed column 2 is inserted into the interior of the sliding hole 32, the surface of the steel ball 33 is rolled and connected to the surface of the steel ball 33, and the surface of the toothed plate 34 is meshed and connected to the bottom of the toothed column 2.

[0032] In this embodiment, the position of the fixing block 31 can be fixed by the meshing of the toothed plate 34 and the toothed column 2.

[0033] Specifically, the limiting groove 36 is trapezoidal, the end face of the first bolt 310 is arc-shaped, and the end face of the first bolt 310 abuts against the inner wall of the limiting groove 36. Under normal conditions, the sliding column 35 slides away from the sliding hole 32 due to the elasticity of the spring 39.

[0034] In this embodiment, by setting a spring 39, when the first bolt 310 is not connected to the inner wall of the limiting groove 36, the sliding column 35 can be reset, so that the toothed plate 34 is away from the toothed column 2.

[0035] Specifically, there are two abutment rods 78, and the end faces of the two abutment rods 78 abut against the surfaces of the sliding plate 4 and the second guide plate 8, respectively. The inside of the sealing groove 76 is under high pressure, and the outer surface of the nut 75 is fixedly connected to the inside of the first guide plate 7.

[0036] In this embodiment, due to the abutment 78 abutting against the sliding plate 4 and the second guide plate 8, the sliding plate 4 and the second guide plate 8 can rotate to adapt to the bending of the side.

[0037] The working principle and usage process of this utility model are as follows: In use, by rotating the first bolt 310, the end face of the first bolt 310 slides away from the sliding post 35. Due to the elasticity of the spring 39, the sliding post 35 slides downwards, causing the toothed plate 34 to slide downwards. When the surface of the toothed plate 34 is no longer engaged with the surface of the toothed post 2, the fixing block 31 can slide freely outside the toothed post 2 through the sliding hole 32. The fixing block 31 is slid until the surface of the sliding plate 4 is tightly against the side mold surface. Then, by rotating the first bolt 310 in the opposite direction, and through the abutment between the first bolt 310 and the sliding post 35, the sliding post 35 and the toothed plate 34 slide upwards, causing the surface of the toothed plate 34 to engage with the surface of the toothed post 2. At this point, the position of the sliding plate 4 is fixed. Then, by rotating the second bolt 74, the second bolt 74 engages with the nut 75, causing the turntable 73 to rotate and the rubber sealing plate 72 to slide, thus sealing the cavity 71. Internal pressurization, along with increased pressure within the sealing groove 76, ensures that when the surface of the abutment 78 is firmly pressed against the surfaces of the sliding plate 4 and the second guide plate 8, and simultaneously when the surfaces of the first guide plate 7 and the second guide plate 8 are in close contact with the outside of the side formwork, the rotation of the second bolt 74 is stopped. Then, by starting the main body 1 of the three-roller paver, the road concrete can be laid. Through the obstruction of the sliding plate 4, the first guide plate 7, and the second guide plate 8, excess concrete is prevented from falling outside the side formwork, eliminating the need for dedicated personnel to clean the concrete outside the side formwork, saving labor costs and cleaning time. Construction personnel can then focus more on other key construction stages, reducing the number of interruptions during construction, ensuring the continuity of the construction process, and thus accelerating the construction progress. It also prevents concrete from falling outside the side formwork and becoming waste, ensuring that every unit of concrete is effectively utilized, reducing concrete waste. In large-scale engineering construction, this can save considerable material procurement costs for the project.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
