Description

Technical Field

[0001] The present application relates to the technical field of highway concrete repair equipment, and in particular to an in-situ slipform repair device for the surface layer of a concrete curbstone. Background Art

[0002] The central median of a monolithic highway roadbed primarily utilizes a raised design, with precast concrete curbstones installed around the perimeter. Concrete curbstones are categorized by their structural shape into straight and curved shapes. Straight concrete curbstones are categorized by their cross-section into H-, T-, R-, F-, P-, and RA-types. These curbstones are installed between the central median and the left curb strip, typically atop a semi-rigid base structure of cement-stabilized aggregate. As small, non-load-bearing precast concrete components along highways, they are characterized by their length and large quantity. As highways age, the concrete curbstones, exposed to cyclical erosion from the external environment (such as climate, high salt content, and freeze-thaw conditions), experience physical and chemical corrosion, as well as freeze-thaw damage. The exposed concrete surface exhibits varying degrees of surface damage, including efflorescence, cracking, peeling, flaking, exposed concrete, and loosening. This damage results in structural and functional defects in the concrete curbstones. Furthermore, the loose particles formed by the exposed concrete concrete pose a significant threat to driving safety.

[0003] When repairing existing concrete curbs on highways, the traditional method of excavation and centralized replacement is often used. This involves multiple steps, complex processes, and a long cycle. It also leads to the transportation and storage of large amounts of waste, resulting in not only a waste of resources but also disturbance and damage to the surrounding area. In routine maintenance, manual local repairs using ordinary mortar are also used. However, this method is inefficient and difficult to integrate with the original concrete curb after repair. Furthermore, ordinary mortar has low strength, long curing times, and poor adhesion, weather resistance, and durability. Repairs quickly lead to re-damage, seriously affecting the appearance and service life of highway concrete curbs. Utility Model Content

DETAILED DESCRIPTION

[0032] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0033] In this disclosure, unless otherwise indicated, directional terms such as "upper" and "lower" generally refer to the relative positions of the corresponding components in the direction of gravity when in use. "Inside" and "outside" refer to the relative positions of the corresponding components themselves. Furthermore, the terms "first" and "second" used in this disclosure are intended to distinguish one element from another and do not convey sequential or significant meanings. In the following description, when referring to the drawings, unless otherwise indicated, identical reference numerals in different drawings indicate identical or similar elements.

[0034] Please refer to Figures 1 to 10 A concrete curb surface in-situ slipform repair device is used to repair surface damage of a concrete curb 8. The concrete curb surface in-situ slipform repair device includes: a frame assembly 1, a mixing tank 22, a feeding assembly 3 and a repair mold 4.

[0035] Please refer to Figure 2 and Figure 5 The frame assembly 1 includes a frame body 101, and a steering wheel set 102 and a driving wheel set 103 arranged at the bottom of the frame body 101. Figure 2 and Figure 3 The mixing tank 2 is mounted on the vehicle frame 101 and includes a tank body 201 and an agitator 202. The tank body 201 has a first feed port and a first discharge port at the bottom of the tank body 201. The mixing tank 2 is used to stir the repair material. The raw material for the repair material can be high-strength polymer mortar powder. A water tank and water pump can also be installed on the vehicle frame assembly 1 to enable the repair material to be prepared on-the-go.

[0036] Please refer to Figure 3 The feeding assembly 3 is disposed at the bottom of the tank body 201 and includes a feeder 301 having a second feed port 302 and a second discharge port 303. The second feed port 302 is connected to the first discharge port. The feeder 301 can be a screw feeder or other feeder, which is not limited in this application.

[0037] Please refer to Figure 2 and Figure 4The repair mold 4 is connected to the side of the frame assembly 1 through the connecting frame 5. The repair mold 4 includes a molding section 401, a transition section 402 and a gathering section 403 which are sequentially connected along the moving direction of the frame assembly 1; wherein, the molding section 401 matches the shape of the top surface 8021 and the inner side surface 8022, and the spacing between the molding section 401 and the top surface 8021 and the inner side surface 8022 is L1; the gathering section 403 matches the shape of the top surface 8021 and the inner side surface 8022, and the spacing between the molding section 401 and the inner side surface 8022 is L2, and L2>L1; in this way, the size of the gathering section 403 is larger than that of the molding section 401, and the gathering section 403 can accommodate sufficient repair material, and the transition section 402 adopts a gradual structure to connect the molding section 401 and the gathering section 403, so that the repair material can be smoothly transitioned from the gathering section 403 to the molding section 401. The forming section 403 has a third feed port 404, which is connected to the second discharge port 303. When L1 is equal to or greater than 0, the inner side of the forming section 401 is flush with the surface of the original concrete curb 8. When L1 is greater than or equal to 0, the repaired surface of the concrete curb is higher than the surface of the original concrete curb 8.

[0038] In the above embodiment, since the repair mold 4 is connected in parallel to the side of the frame assembly 1, Figure 4 The repair mold 4 is provided with a third feed port 404. As the vehicle frame assembly 1 moves forward or backward along the concrete curb 8, the repair mold 4 can also move forward or backward along the concrete curb 8. When repairing the surface damage of the concrete curb 8, the repair material raw materials are added from the first feed port of the mixing tank 201 and stirred using the agitator 202. After the repair material is ready, the frame assembly 1 is placed close to the concrete curb 8 and parallel to the extension direction of the concrete curb 8, so that the repair mold 4 is buckled on the contour of the concrete curb 8 with surface damage, and the frame assembly 1 is started to move forward while the feeding assembly 3 is started. The repair material enters the second feed port 302 of the feeding assembly 3 from the first discharge port at the bottom of the tank body 201, is transported to the second discharge port 303 through the feeding assembly 3, and enters the inner side of the material gathering section 403 of the repair mold 4 from the third feed port 404 on the repair mold 4. Since the size of the material gathering section 403 is larger than the size of the forming section 401, the material gathering section 403 can accommodate enough repair material. Therefore, when the frame assembly 1 moves forward and drives the repair mold 4 forward, it can slide to repair the surface damage of the concrete curb 8. The in-situ slipform repair device for the surface of concrete curbstones of the present application can use the repair materials prepared on the spot without changing the position of the existing concrete curbstone 8. It rationally utilizes the existing structure of the concrete of the concrete curbstone 8 and repairs the surface damage of the concrete curbstone 8 on site at one time, so that the repair materials and the concrete of the existing concrete curbstone 8 are integrated and work together. The operation efficiency is high and the construction period is short, thereby quickly restoring the appearance quality, structural strength and use function of the existing concrete curbstone 8.

[0039] Please refer to Figure 3 To ensure that the repair material can fully contact the surface damage of the concrete curb 8, the repair material is evenly distributed and dense, and the damaged space on the surface is fully filled. The concrete curb surface in-situ slipform repair device can also include a vibrator 6. The vibrator 6 is provided on the outer surface of the transition section 402 of the repair mold 4 and is used to apply a vibration excitation force to the transition section 402 to ensure that the repair material inside the transition section 402 is evenly distributed and dense.

[0040] In actual repair situations, the height of the concrete curb 8 may be uneven, and the height difference between the road surface and the top surface of the concrete curb 8 may be uneven. In order to adapt to the different height differences between the road surface and the concrete curb 8, it is necessary to make the repair template movable in the vertical direction. In one embodiment of the present application, please refer to Figure 5 Two vertical guide rods 1011 are provided on the side of the frame body 101, and guide grooves are provided on the opposite sides of the two vertical guide rods 1011. Slide blocks 1012 are provided in the guide grooves, and the repair mold 4 is connected to the slide blocks 1012 through the connecting frame 5. The in-situ slipform repair device for the surface of the concrete curb can also include a linear drive device 7. The linear drive device 7 can include a hydraulic cylinder 701, and an oil tank 702 and an oil pump 703 for supplying oil to the hydraulic cylinder 701. The cylinder body of the hydraulic cylinder 701 is connected to the frame body 101, and the piston rod of the hydraulic cylinder 701 is connected to the slide blocks 1012. In this way, when it is necessary to adjust the height of the repair mold 4 or the thickness of the repair material, it can be achieved by adjusting the length of the piston rod of the hydraulic cylinder 701. The use of the hydraulic cylinder 701 can ensure that the extension length of the piston rod is stable and reliable, so that the thickness of the repair surface remains consistent. In other embodiments, the linear drive device 7 can also be an electric push rod, which is not limited in this application.

[0041] In order to prevent the preparation process of the repair material and the repair process from affecting each other, a discharge door 203 is provided at the bottom of the tank 201. The discharge door 203 is used to selectively close the first discharge port. When the discharge door 203 is closed, the raw materials of the repair material can be fully mixed in the tank 201. When the repair work is suspended, the repair material can also be temporarily stored in the tank 201. Please refer to Figure 6 Two discharge doors 203 are hinged at the bottom of the tank body 201, and the two discharge doors 203 can be driven by two hydraulic cylinders 701 to open or close.

[0042] Please refer to Figure 3In one embodiment of the present application, the feeder 301 may be a screw feeder 301; the second feed port 302 is a hopper disposed at the bottom of the tank body 201; the screw feeder 301 has a flexible delivery tube 304, one end of which is connected to the discharge port of the screw feeder 301, and the other end is connected to the third feed port 404. Thus, when the repair mold 4 is raised or lowered, the flexible screw feed tube can automatically adapt to the raising or lowering of the repair mold 4.

[0043] Please refer to Figure 1 , the protrusion 802 has an outer side surface 8023 facing away from the road; please refer to Figure 4 The forming section 401 has a first baffle 4011 that abuts against the outer side surface 8023. In this way, on the one hand, the first baffle 4011 can prevent the repair material from flowing from the top surface 8021 of the concrete curb 8, and on the other hand, it can guide the progress of the repair template 4 and control the new repair line shape. Figure 4 The edge of the forming section 401 close to the road side may have a second baffle 4012 extending downward to prevent the repair material from flowing out.

[0044] Please refer to Figure 2 and Figure 7 In one embodiment of the present application, the steering wheel assembly 102 includes a steering motor 1021 and two steering wheels 1022. The two steering wheels 1022 are rotatably connected to the vehicle frame, and the output shaft of the steering motor 1021 is in transmission connection with the steering wheels 1022. Figure 7 The steering motor 1021 can be fixedly connected to the bottom of the frame, the output shaft of the steering motor 1021 is connected to the gear 1023, and a rack 1024 is slidably connected to the frame, and the rack 1024 is engaged with the gear 1023. The two ends of the rack 1024 are respectively hinged to the two steering wheels 1022 through connecting rods 1025. By starting the steering motor 1021 to rotate forward or reverse, the two steering wheels 1022 can be controlled to rotate synchronously, thereby controlling the travel direction of the frame assembly 1.

[0045] Please refer to Figure 2 In one embodiment of the present application, the drive wheel assembly 103 includes a drive motor and two drive wheels, and the drive motor is in driving connection with the two drive wheels. In other embodiments, other power devices, such as gasoline engines or diesel engines, can also be used as the power source of the repair device, and this application does not limit this.

[0046] Please refer to Figure 2In one embodiment of the present application, the in-situ slipform repair device for the concrete curb surface may further include a control system comprising a main control panel and a plurality of control knobs 9. The steering motor 1021, drive motor 1031, and oil pump 703 are all electrically connected to the main control panel. This allows a worker to control the steering motor 1021, drive motor 1031, and oil pump 703 using the control knobs 9, thereby achieving automated control of the repair device.

[0047] Please refer to Figure 2 and Figure 3 In one embodiment of the present application, the in-situ slipform repair device for the concrete curb surface may further include a laser line-projecting device 10, which is mounted on the connecting frame 5 and is used to project a line onto the concrete curb 8, serving as a reference line for the repair mold 4. In this way, during the repair of the concrete curb 8, workers can use the reference line as a guide to move the frame assembly 1 along the reference line, thereby improving the quality and efficiency of the repair.

[0048] Please refer to Figure 1 、 Figure 8 and Figure 9 According to one embodiment of the present application, the concrete curb 8 may include an RA type concrete curb (such as Figure 1 and Figure 8 ), H-type concrete curbstone (such as Figure 9 ), T-type concrete curbstone (not shown in the drawings), R-type concrete curbstone (not shown in the drawings), F-type concrete curbstone (not shown in the drawings), and P-type concrete curbstone (not shown in the drawings).

By configuring the concrete curbstone surface in-situ slipform repair device with multiple repair molds 4, the concrete curbstone surface in-situ slipform repair device can be applied to a variety of concrete curbstones 8, thereby expanding the scope of application of the repair device.

[0049] Please refer to Figure 2 and Figure 10A joint marker 11 can also be provided at the tail end of the repair mold 4. The joint marker 11 can include a motor provided on the repair mold 4 and a blade provided on the motor output shaft, and the blade extends from the tail end of the repair mold 4. The motor can be electrically connected to the main control board. The staff can set the rotation speed or rotation time of the motor so that the blade rotates and marks are left on the concrete surface after molding, which is convenient for manual grouting in the later stage, so that the repaired surface of the concrete curb 8 and the surface of the original concrete curb 8 have joint grooves with the same spacing, achieving the effect of repairing the old as if it were new.

[0050] The following is an example of the steps for repairing concrete curbstones to illustrate the working principle of the repair device of this application: 1. Device operation mode

[0061] 5. The mixing tank and repair mold adopt an integrated design, which allows for on-site mixing and immediate use according to the quantity. This effectively solves the technical problem of short operating time of polymer mortar, avoids material waste, and improves construction efficiency.

[0062] 6. The control system can set construction parameters according to different working conditions, different concrete curb structures, etc., and can realize automatic operation or manual control of the equipment, which is conducive to dealing with various emergencies on the construction site. The construction operation is highly flexible and adaptable.
