Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a concrete turnover device and a method for rapid repair of curb stones. Background Technology

[0002] Existing curb stones are prone to sudden breakage, chipping, and other defects due to improper traffic behavior by vehicles and pedestrians, as well as the inherent low strength of the curb stones themselves and the effects of thermal expansion and contraction during winter and rainy seasons. This necessitates the removal and repaving of damaged sections to improve the overall quality and aesthetics of the road surface. Traditional repair work requires the prior planning of temporary concrete storage facilities on-site. Once the concrete arrives on-site, its handling is inconvenient, and it's impossible to re-mix the long-waiting concrete to ensure its workability.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, a concrete turnover device and a rapid repair method for curb stones are provided to solve the problems of inconvenient concrete turnover and secondary mixing in the existing curb stone repair process.

[0005] To achieve the above objectives, a concrete turnover device is provided, comprising:

[0006] A mobile container for holding concrete, wherein a discharge port is formed on one side of the mobile container and a perforation is provided at the bottom of the mobile container;

[0007] A tube shaft is rotatably inserted into the through hole, the upper part of the tube shaft extends into the movable box and is coaxially connected to an inner cylinder, and stirring blades are connected to the outer wall of the inner cylinder;

[0008] A wheel is coaxially connected to the lower end of the tube shaft. The outer edge of the wheel is rotatably connected to a first drive wheel, which is arranged along an outer tangent of the wheel. During the movement of the mobile box, the first drive wheel drives the wheel to rotate, which in turn drives the mixing blades on the inner cylinder to mix the concrete in the mobile box through the tube shaft.

[0009] Furthermore, the wheel has a guide hole communicating with the opening of the tube shaft. A lifting rod is movably inserted through the guide hole and the tube shaft. The upper end of the lifting rod extends to the inner cylinder and is connected to a piston plate. The piston plate slides in the inner cylinder. A second drive wheel is rotatably mounted below the wheel. The second drive wheel is arranged along the traveling direction of the moving box. The second drive wheel is connected to an eccentric shaft. A drive rod is hinged between the eccentric shaft and the lower end of the lifting rod. After the second drive wheel rotates, the drive rod drives the lifting rod to slide along the axial direction of the tube shaft, so that the piston plate discharges the concrete in the inner cylinder into the moving box.

[0010] Furthermore, the inner cylinder has a feeding port on its side wall.

[0011] Furthermore, the inner cylinder has an upper opening and a lower opening, and the upper end of the tube shaft is connected to the lower opening of the inner cylinder by multiple spokes.

[0012] Furthermore, the spokes are arranged along the radial direction of the inner cylinder.

[0013] Furthermore, rollers are installed on opposite sides of the mobile box.

[0014] Furthermore, the top of the mobile box is provided with a feeding port.

[0015] Furthermore, a valve is installed in the discharge port.

[0016] This invention provides a method for rapid repair of curb stones using a concrete turnover device, comprising the following steps:

[0017] The old, damaged curb stones in many places on the road surface were removed;

[0018] Strengthen the underlying soil.

[0019] The subgrade is formed by pouring the compacted subgrade soil.

[0020] Backrest ribs are arranged on the padding layer;

[0021] The concrete is poured into the mobile container of the concrete turnover device;

[0022] The mobile box is moved to the repair site of the road surface using a traction device. During the movement of the mobile box, the first drive wheel drives the wheel to rotate, which in turn drives the mixing blades on the inner cylinder to mix the concrete in the mobile box through the tube shaft.

[0023] Align the discharge port of the mobile container with the repair site and open the discharge port. Pour the concrete from the mobile container into the repair site, so that the concrete covers the backrest reinforcement to solidify and form a new curbstone.

[0024] The beneficial effects of this invention are that, when repairing curb stones, the concrete turnover device of this invention loads concrete into a mobile container. During the movement of the mobile container, since the first drive wheel is set along an outer tangent of the wheel disc, the first drive wheel contacts the ground and drives the wheel disc to rotate around the axis of the wheel disc. In turn, the mixing blades on the inner cylinder are driven by the pipe shaft to mix the concrete in the mobile container. On the one hand, it provides a secondary mixing and moving device for curb stone repair. On the other hand, it avoids setting up a pre-set temporary concrete storage point on the road surface, making it convenient to turnover the concrete after it arrives at the site and ensuring the workability of the concrete.

[0031] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Reference Figures 1 to 5 As shown, the present invention provides a concrete turnover device, comprising: a mobile box 1, a pipe shaft 2, and a wheel 3.

[0034] The movable container is used to hold concrete. A discharge port 10 is formed on one side of the movable container 1. A perforation is provided at the bottom of the movable container 1.

[0035] In this embodiment, the movable box 1 is cubic in shape. A feeding port is located at the top of the movable box 1. A discharge port is located on the side of the movable box. A valve is installed in the discharge port 10.

[0036] Rollers 11 are installed on opposite sides of the mobile box 1. Specifically, the rollers are located on opposite sides of the mobile box. The rollers are positioned along the direction of travel of the mobile box.

[0037] Continue reading Figure 1 As shown, the mobile container has a front end and a rear end. A traction cable 12 is connected to the front end of the mobile container. The discharge port is located on the right side of the mobile container.

[0038] The tube shaft 2 is rotatably inserted into the perforation. The upper part of the tube shaft 2 extends into the movable box 1. The inner cylinder 21 is coaxially connected to the tube shaft 2. The outer wall of the inner cylinder 21 is connected to the mixing blades 22. When the movable box is filled with concrete, the inner cylinder is rotated by the tube shaft, causing the mixing blades to agitate the concrete inside the movable box.

[0039] The wheel 3 is coaxially connected to the lower end of the tube shaft 2. The outer edge of the wheel 3 is rotatably connected to the first drive wheel 31. The first drive wheel 31 is arranged along an outer tangent of the wheel 3. During the movement of the moving box 1, the first drive wheel 31 drives the wheel 3 to rotate, which in turn drives the mixing blades 22 on the inner cylinder 21 to mix the concrete in the moving box 1 through the tube shaft 2.

[0040] The concrete turnover device of the present invention loads concrete into a mobile container when repairing curb stones. During the movement of the mobile container, the first drive wheel is set along an outer tangent of the wheel disc. The first drive wheel contacts the ground and drives the wheel disc to rotate around the axis of the wheel disc. In turn, the mixing blades on the inner cylinder are driven by the pipe shaft to stir the concrete in the mobile container. On the one hand, it provides a secondary mixing and moving device for curb stone repair. On the other hand, it avoids setting up a pre-set temporary concrete storage point on the road surface, making it convenient to turnover the concrete after it arrives at the site and ensuring the workability of the concrete.

[0041] In this embodiment, the wheel 3 has a guide hole communicating with the opening of the tube shaft 2. A lifting rod 4 is movably inserted through the guide hole and the tube shaft 2. The upper end of the lifting rod 4 extends to the inner cylinder 21 and is connected to a piston plate 41. The piston plate 41 is slidably disposed in the inner cylinder 21. A second drive wheel 32 is rotatably mounted below the wheel 3. The second drive wheel 32 is arranged along the traveling direction of the moving box 1. The second drive wheel 32 is connected to an eccentric shaft 43. A drive rod 42 is hinged between the eccentric shaft 43 and the lower end of the lifting rod 4. After the second drive wheel 32 rotates, the drive rod 42 drives the lifting rod 4 to slide along the axial direction of the tube shaft 2, so that the piston plate 41 discharges the concrete in the inner cylinder 21 into the moving box 1.

[0042] The piston plate moves up and down, pushing the concrete on both sides of the inner cylinder to exchange, which improves the workability of the concrete.

[0043] In this embodiment, the inner cylinder 21 has an upper opening and a lower opening. The upper end of the tube shaft 2 is connected to the lower opening of the inner cylinder 21 by multiple spokes.

[0044] As a preferred embodiment, the spokes are arranged radially along the inner cylinder 21.

[0045] See Figure 3 As shown, the inner cylinder 21 has a feeding port on its side wall. During the rotation of the second drive, the piston plate is pushed from the bottom to the top of the inner cylinder by the lifting rod, so that the concrete in the inner cylinder is discharged to the outside of the inner cylinder. The concrete on the outside of the inner cylinder is replenished into the inner cylinder through the feeding port and the bottom of the inner cylinder. After the piston plate reaches the top of the inner cylinder, the piston plate discharges the concrete that has been replenished into the inner cylinder to the outside of the inner cylinder. Thus, the reciprocating motion of the piston plate accelerates the mixing speed of the concrete on the inner and outer sides of the inner cylinder.

[0046] This invention provides a method for rapid repair of curb stones using a concrete turnover device, comprising the following steps:

[0047] S1. Remove the old curb stones that are damaged in many places on the road surface.

[0048] S2. Compact the soil at the bottom of the foundation.

[0049] S3. The subgrade is formed by pouring the compacted soil.

[0050] S4. Lay backrest reinforcement bars on the padding layer.

[0051] S5. Pour the concrete into the mobile box 1 of the concrete turnover device.

[0052] S6. Using the traction cable 12 pulled by the traction equipment, the mobile box 1 is moved to the road repair site. During the movement of the mobile box 1, the first drive wheel 31 drives the wheel disk 3 to rotate, which in turn drives the mixing blades 22 on the inner cylinder 21 to mix the concrete in the mobile box 1 through the pipe shaft 2.

[0053] S7. Align the discharge port 10 of the mobile box 1 with the repair area and open the discharge port 10. Pour the concrete in the mobile box 1 into the repair area so that the concrete covers the backrest reinforcement and solidifies to form a new curbstone.

[0054] The present invention provides a rapid road curb repair construction method using a concrete turnover device. For road curb repair construction, the repair work is carried out by storing and mixing concrete in a self-rotating inner cylinder and a moving box.

[0055] The pre-construction preparations for the rapid curbstone repair method using a concrete turnover device according to the present invention include:

[0056] 1) Before construction, damaged curb stones should be removed and cleaned. Backing bars with a diameter of 10mm should be added to the curb stone edge. The bars should be embedded 200mm into the retaining base and exposed 50mm. The backing bars should be spaced 1.0m apart.

[0057] 2) Before construction, investigate the traffic volume of vehicles and pedestrians along the route, as well as the pipelines and obstacles around the construction area. If there are any conflicting locations, please report them in a timely manner.

[0058] 3) The soil at the bottom of the curbstone foundation should be compacted.

[0059] 4) Before and during the repair work, vehicles are strictly prohibited from passing through the work area.

[0060] 5) During the construction process, it is strictly forbidden to stop work for more than 2 hours at a time.

[0061] 6) Before repairing the equipment, wet it with water and check the movement of each moving part to ensure that the operation is smooth and unobstructed.

[0062] Technical requirements for curbstone construction:

[0063] 1) The design strength grade of the concrete is C30.

[0064] 2) The back reinforcement of the curbstone side formwork is 250mm long. The formwork is made of lightweight bamboo plywood, and the thickness of the bamboo plywood should not be less than 12mm.

[0065] 3) After the repair work is carried out, it should be maintained in accordance with the specifications.

[0066] 4. Advantages and technical requirements of self-mixing mobile container construction

[0067] 1) Self-stirring mobile container, the container body is made of 10mm thick steel plate.

[0068] 2) The self-mixing mobile box has a high safety factor in operation and use, and does not require the full-section closure of the road section for traditional repair operations, but only the closure of a single lane.

[0069] 3) The self-stirring mobile box and the tube shaft are connected by bearings, and the stirring blades are double-sided welded.

[0070] 4) Traditional repair work requires the planning of temporary concrete storage equipment on site in advance. After the concrete arrives on site, the turnover is not fixed and it is impossible to re-mix the concrete material that has been waiting for a long time to ensure its workability. The self-mixing mobile box can not only freely drag the concrete to the repair work area, but its own rotation function can simulate the concrete truck's mixing tank and mix the concrete. It has the advantages of no leakage and no waste in the repair work area.

[0071] 5) The self-mixing mobile container should be able to be towed manually or by a small pickup truck according to the repair spacing and repair length, which makes it easier to manage on site and is more convenient and efficient.

[0072] Before repair work, all damaged sections must be chiseled away and cleaned. In addition to compacting the base before construction, ensuring a compaction degree no less than 96% of the required compaction degree for the same roadbed section, the sections must also be properly moistened with water. The bamboo plywood used for formwork must be at least 10mm thick and have flat, warped ends. Before construction, workers should implement temporary road control measures in accordance with municipal construction safety requirements for the repair section, assigning dedicated personnel for traffic guidance and management.

[0073] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
