Description
Technical Field
[0001] The invention belongs to the technical field of road construction, in particular to a concrete paving machine with adjustable thickness. Background Art
[0002] Concrete laying machine is a kind of mechanical equipment widely used in civil and construction engineering. Its main function is to lay concrete materials evenly and continuously in a designated area and to level and compact them. At present, the traditional concrete laying machine is to place the device at the location where paving is required. After the machine is positioned, the roller is driven to rotate, and the concrete is effectively transported from the storage or supply point to the paving area. During this process, the rotation speed and direction of the roller can be adjusted according to actual needs to ensure that the concrete can be evenly and continuously distributed in the predetermined area. After the concrete is basically laid, the roller is driven to rotate to level and compact the concrete; However, in actual projects, the thickness of the concrete layer may vary due to various factors such as design requirements, foundation conditions, construction environment, etc., and the existing laying machines cannot flexibly adjust the position of their working parts according to the changes in the thickness of the concrete. Specifically, when the concrete layer is thinner, if the position of the winder roller and the rotating roller is still maintained at a higher position, the concrete may be over-compacted and may even be damaged or cracked. On the contrary, when the concrete layer is thicker, if the position of the winder roller and the rotating roller is too low, the concrete may not be fully leveled and compacted, which will reduce the flexibility of the device and affect the laying quality and the subsequent construction process.

DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] like Figures 1 to 7 As shown, the present invention provides a thickness-adjustable concrete paving machine, comprising a housing 1, wherein a rotating roller 2 and a twisting roller 3 are arranged inside the housing 1; An adjusting mechanism is arranged inside the shell 1, and the adjusting mechanism includes a mounting rod 4. There are four mounting rods 4, and each two mounting rods 4 form a group and are located inside the shell 1. Square plates 5 are fixedly installed on opposite sides of the two mounting rods 4, and a motor 6 is fixedly installed on the bottom end of the square plate 5. The output end of the motor 6 passes through the square plate 5 and is fixedly installed with a worm 7. The top of the square plate 5 is rotatably connected to a worm wheel 8 meshing with the worm 7, and a push rod 9 is fixedly installed on one side of the worm wheel 8. A fixing rod 10 is fixedly installed inside the shell 1, and a connecting block 11 located inside the push rod 9 is fixedly installed on one side of the fixing rod 10.
[0019] The above scheme is adopted: the operator places the device on the top of the concrete to be paved, and then drives the twist roller 3 to rotate. When the twist roller 3 rotates, the concrete will be evenly transported to the area to be paved, and then the rotating roller 2 can be driven to rotate, and the rolling of the rotating roller 2 can realize the leveling and compaction of the concrete; When the device needs to be adjusted according to the thickness of concrete, the motor 6 can be driven to rotate the worm 7. Since the worm 7 is meshed with the two worm wheels 8, the worm 7 will drive the worm wheel 8 to rotate, and the worm wheel 8 will drive the push rod 9 to rotate. When the push rod 9 rotates, the connecting block 11 will slide inside the push rod 9, and the push rod 9 will push the connecting block 11 and the fixed rod 10 to move upward, and the fixed rod 10 will drive the shell 1 to move upward, and the shell 1 will drive the rotating roller 2 and the twisting roller 3 to move upward, and then the rotating roller 2 and the twisting roller 3 can be moved to a position suitable for the thickness of concrete, and the paving work can be continued. Finally, the driving motor 6 makes the pushing rod 9 push the entire device to move, so that it can pave concrete of different thicknesses, thereby improving the flexibility of the device.
[0020] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, it also includes: a vibration mechanism, which is arranged at the top of the shell 1, and the vibration mechanism includes a fixed shell 12, the fixed shell 12 is fixedly connected to the top of the shell 1, a sliding plate 13 is arranged inside the fixed shell 12, a vibration plate 14 is fixedly installed at the bottom end of the sliding plate 13, a sliding hole 15 is opened on the surface of the sliding plate 13, a slider 16 is slidably connected inside the sliding hole 15, a sliding ring 17 is fixedly installed on one side of the slider 16, a motor 18 is fixedly installed inside the fixed shell 12, a push rod 19 is fixedly installed at the output end of the motor 18, and a protrusion 20 located inside the sliding ring 17 is fixedly installed on one side of the push rod 19.
[0021] The above scheme is adopted: through the design of the vibration mechanism, after the twisting roller 3 evenly transports the concrete to the area to be laid, the motor 2 18 can be driven to rotate the push rod 2 19, and the push rod 2 19 will drive the protrusion 20 to slide inside the sliding ring 17, and then the push rod 2 19 and the protrusion 20 will push the sliding ring 17 to move back and forth, and the sliding ring 17 will drive the slider 16 to slide inside the sliding hole 15. In the process of sliding of the slider 16, the sliding plate 13 will be driven to move back and forth, and the sliding plate 13 will drive the vibration plate 14 to move back and forth. In the process of reciprocating movement of the vibration plate 14, it will contact the surface of the concrete, and then the concrete can be preliminarily vibrated. Then, through the cooperation between the rotating roller 2 and the twisting roller 3, the concrete is leveled and compacted. Finally, the vibration plate 14 is driven by the motor 2 18 to preliminarily vibrate the concrete, effectively eliminating bubbles and gaps in the concrete, and through vibration, the concrete can be made more uniform, thereby improving its density.
[0022] like Figure 6As shown, a limiting rod 21 located inside the sliding ring 17 is fixedly installed inside the fixed shell 12, the number of the limiting rods 21 is two, and they are designed to be laterally symmetrical about the center of the fixed shell 12, the limiting rod 21 is square in design, and the surface of the limiting rod 21 fits with the inner wall of the sliding ring 17, and a spring 22 is fixedly installed inside the fixed shell 12, the top end of the spring 22 is fixedly connected to the sliding plate 13, and the spring 22 is designed to be longitudinally symmetrical about the center of the sliding plate 13.
[0023] The above solution is adopted: through the design of the limit rod 21, when the sliding ring 17 moves along the preset trajectory, it will slide closely on the surface of the limit rod 21. This design is not only to ensure the stability of the sliding ring 17 during movement, but more importantly, the surface of the limit rod 21 and the inner wall of the sliding ring 17 are nearly seamlessly fitted. This tight fit not only reduces the laying error caused by shaking or misalignment, but also significantly enhances the rigidity and durability of the entire structure. The limit rod 21 is symmetrically designed, which can increase its limiting effect. Through the design of the spring 22, when the sliding plate 13 moves along the preset trajectory, the sliding plate 13 can slide closely on the surface of the limit rod 21. When the path moves back and forth, the spring 22 will perform telescopic movement accordingly. This design not only makes full use of the excellent restoring performance of the spring 22, but also effectively reduces the load of the motor 18. The elastic action of the spring 22 can absorb and store part of the kinetic energy generated by the movement of the sliding plate 13, so that when the sliding plate 13 changes its direction of movement or stops moving, the spring 22 can release the stored energy to help the sliding plate 13 to reset smoothly and quickly, thereby extending the service life of the motor. In addition, the spring 22 is symmetrically designed, so when the two springs 22 simultaneously push the sliding plate 13 to reset, the stability of the movement of the sliding plate 13 can be increased.
[0024] like Figure 1 , Figure 3 and Figure 4 As shown, a limiting groove 23 is opened inside the shell 1, and the limiting groove 23 is internally slidably connected to a limiting block 24, and one side of the limiting block 24 is fixedly connected to the surface of the mounting rod 4. The limiting groove 23 and the limiting block 24 are T-shaped, and the surface of the limiting block 24 fits the inner wall of the limiting groove 23. The mounting rod 4 is internally rotatably connected with a roller 25. The number of the rollers 25 is four, and the rollers 25 are grouped in pairs and are located inside the shell 1.
[0025] The above scheme is adopted: through the design of the limit groove 23 and the limit block 24, when the installation rod 4 moves, the limit block 24 will be driven to slide inside the limit groove 23, so as to limit the installation rod 4, and the limit block 24 is of T-shaped design, which not only enables the limit block 24 to slide firmly in the limit groove 23, avoiding the movement deviation caused by shaking or external force interference, but also provides all-round limit support for the installation rod 4 through its unique structural form, the transverse part of the T-shaped limit block 24 is tightly fitted with the side wall of the limit groove 23, effectively preventing the installation rod 4 from deviating in the horizontal direction; and its longitudinal part goes deep into the interior of the limit groove 23, ensuring the stability of the installation rod 4 in the vertical direction, Through the design of the roller 25, when the rotating roller 2 and the twisting roller 3 rotate, the entire device will move along a preset route, and when the device moves, the roller 25 will rotate. Through the rotation of the roller 25, the entire device can move more smoothly.
[0026] like Figure 1 and Figure 2 As shown, a scraper 26 located at the top of the roller 2 is fixedly installed inside the shell 1, and the bottom end of the scraper 26 contacts the surface of the roller 2. A sealing plate 27 is provided on one side of the fixed shell 12, and the fixed shell 12 and the sealing plate 27 are hinged by a hinge chain 28.
[0027] The above scheme is adopted: through the design of the scraper 26, since the bottom end of the scraper 26 contacts the surface of the roller 2, when the roller 2 rolls, the scraper 26 can clean the concrete attached to the surface of the roller 2, ensuring that the concrete remains uniform and dense during the paving process, thereby improving the quality of concrete paving. Through the design of the sealing plate 27 and the hinge chain 28, since the fixed shell 12 and the sealing plate 27 are hinged by the hinge chain 28, the sealing plate 27 can be rotated to expose the components inside the fixed shell 12, thereby facilitating the operator to maintain it and improving the service life of the device. After the maintenance of the device is completed, the sealing plate 27 can be loosened, and then the sealing plate 27 will be reset, so that the fixed shell 12 can be sealed, thereby facilitating its protection.
[0028] like Figure 3 , Figure 4 and Figure 7 As shown, the slide hole 15 is of inclined design, and the slider 16 located inside the slide hole 15 is of circular design. The push rods 9 are arranged in groups of two, and the push rods 9 are designed to be transversely symmetrical about the center of the housing 1.
[0029] The above scheme is adopted: through the design of the sliding hole 15, since the sliding hole 15 is inclined, when the slider 16 moves, it can drive the sliding plate 13 to move back and forth, and the slider 16 located inside the sliding hole 15 is circular in design, so that the slider 16 can move more smoothly. Through the design of the push rod 9, since the push rod 9 is symmetrical in design, when the push rod 9 pushes the shell 1 to move upward, its movement stability can be increased.
[0030] The working principle and use process of the present invention: First, the operator can place the device on the top of the concrete to be paved, and then drive the twist roller 3 to rotate. When the twist roller 3 rotates, the concrete will be evenly transported to the area where it needs to be paved. After the transportation is completed, the motor 2 18 can be driven to rotate the push rod 2 19 and the protrusion 20. The push rod 2 19 will push the sliding ring 17 to move back and forth, and the sliding ring 17 will drive the slider 16 to slide inside the sliding hole 15, and the slider 16 will drive the sliding plate 13 to move back and forth, and the sliding plate 13 will drive the vibration plate 14 to move back and forth. During the reciprocating movement of the vibration plate 14, it will contact the surface of the concrete, thereby being able to perform preliminary vibration on the concrete. At the same time, the roller 2 can be driven to rotate, and the concrete can be leveled and compacted by the rolling of the roller 2. When the device needs to be adjusted according to the thickness of the concrete, the motor 6 can be driven to rotate the worm 7, and the worm 7 will drive the worm wheel 8 and the push rod 9 to rotate. When the push rod 9 rotates, the connecting block 11 will slide inside the push rod 9, and the push rod 9 will push the connecting block 11 and the fixed rod 10 to move upward, and the fixed rod 10 will drive the entire device to move upward, and then the roller 2 and the twist roller 3 can be moved to a position suitable for the thickness of the concrete, and then the paving work can be continued, and finally the operation process is completed.
