Description

Technical Field

[0001] This invention relates to the field of concrete leveling technology, specifically to a concrete leveling device for riverbank protection in water conservancy projects. Background Technology

[0002] As is well known, riverbank protection in water conservancy projects is a slope protection system that combines ecological protection and engineering safety. It aims to prevent water erosion, stabilize the bank slope, and improve the ecological environment. It often uses hard materials such as cement or masonry. The concrete leveling device for riverbank protection in water conservancy projects is a mechanized equipment used for sloping concrete construction to automatically complete processes such as leveling and smoothing.

[0003] A search revealed Chinese patent application CN202510415629.0, which discloses a concrete leveling device for riverbank protection in water conservancy projects. The device is described as comprising a leveling frame with symmetrically arranged grooves. Movable frames are slidably connected to each groove, and limit plates are fixedly connected to the bottom of each movable frame. Pressure rods are slidably connected to each movable frame. Symmetrically arranged rotating rods are rotatably connected to the top of the leveling frame, and extrusion plates are fixedly connected to each rotating rod. First strong magnetic blocks are fixedly connected inside each extrusion plate. Support plates are fixedly connected to the top of the leveling frame adjacent to the extrusion plates, and second strong magnetic blocks are fixedly connected to one side of each support plate. Chinese patent application CN2024... Patent 11538589.0 discloses a construction process for cast-in-place concrete slope protection slabs. The process generally includes surveying and setting out, erecting templates for the cast-in-place concrete slope protection slabs on the slope, fixing pre-tied reinforcing mesh to the cast-in-place concrete slope protection slabs, and pouring concrete. After the concrete is poured, the construction worker only needs to turn the handwheel to rotate the lead screw. Due to the limiting position of the first support rod, the nut on the lead screw and the first support rod can move along the first slotted hole, thereby moving the second cover plate above the first support plate. Secondly, due to the limitation of the guide rod, the second cover plate can be horizontally positioned between the first support plate and the side wall of the pre-poured cast-in-place concrete slope protection slab, thus allowing the lower surface of the second cover plate to smooth the concrete poured within the template area.

[0004] While the aforementioned existing technical solutions can assist in the leveling of slopes in water conservancy and river engineering, they all require the installation of mold structures to define the concrete boundaries before the slope leveling operation can be completed. This results in the leveling mechanism being overly dependent on the boundary molds, and the direction of the leveling movement being relatively singular. The leveling effect needs further improvement. In reality, the slope protection operation area is often large, requiring the boundary molds to frequently switch operating positions. However, the transfer operation of the leveling mechanism in the above technical solutions is cumbersome, and there is still considerable room for improvement in operational convenience. Summary of the Invention

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] For examples, please refer to Figures 1-16A concrete leveling device for riverbank protection in water conservancy projects includes a mobile frame 1 and a leveling structure. The mobile frame 1 is equipped with a powered track 2 and a synchronous adjustment assembly. The leveling structure includes a first conveyor frame 3 and a second conveyor frame 4, both mounted on the synchronous adjustment assembly. The synchronous adjustment assembly includes a first follower bending frame 11, a second follower bending frame 12, a fixed inner support 13, and two electric telescopic rods 10. The fixed inner support 13 is fixedly connected to the mobile frame 1. The two electric telescopic rods 10 are both installed within the fixed inner support 13. The actuators of the two electric telescopic rods 10 are connected to synchronous shafts 9, which are rotatably connected to the fixed inner support 13. The two synchronous shafts 9 are respectively fixedly connected to a first drive bending frame 14 and a second drive bending frame 15. Both the first drive bending frame 14 and the second drive bending frame 15 are rotatably connected to a side mounting frame 16. The first conveyor frame 3 slides on... The first conveyor frame 3 is equipped with a sliding frame 17, a covering groove 50 and an extension frame 51. Both the covering groove 50 and the extension frame 51 are fixedly connected to rails 52. Each rail 52 is slidably connected to a rail sleeve 53. Both rail sleeves 53 are fixedly connected to the sliding frame 17. The second conveyor frame 4 is fixedly connected to a transfer frame 18. The sliding frame 17 and the transfer frame 18 are rotatably connected to two side transfer frames 16, respectively. The two side transfer frames 16 are rotatably connected to a first following bending frame 11 and a second following bending frame 12, respectively. The first following bending frame 11 and the second following bending frame 12 are rotatably installed on the left and right sides of the mobile frame 1, respectively. Through the design of the synchronous adjustment component, the leveling structure and the double-sided limiting structure are integrated on the mobile frame 1. This not only ensures the coordinated operation of the leveling structure and the double-sided limiting structure and improves the overall construction efficiency, but also facilitates the combination and storage of the equipment and reduces the transportation and storage costs of the equipment.

[0040] It should be further explained that the first conveyor frame 3 and the second conveyor frame 4 are rotatably connected to each other. A first servo motor 5 is mounted on the second conveyor frame 4, and a cantilever frame 56 is fixedly connected to it. The first servo motor 5 is mounted on the cantilever frame 56. A rear extension frame 57 is fixedly connected to the first conveyor frame 3, and a rotating cylinder 58 is fixedly connected inside the rear extension frame 57. The rotating cylinder 58 is rotatably connected to the cantilever frame 56 and connected to the output shaft of the first servo motor 5. The first servo motor 5 is used for angle adjustment of the first conveyor frame 3 relative to the second conveyor frame 4. Leveling conveyor belts 6 are installed inside both the first conveyor frame 3 and the second conveyor frame 4. Multiple actuating plates 7 are installed outside both leveling conveyor belts 6. Through the design of the leveling structure, a suitable leveling effect is achieved. The driving leveling system for concrete construction can complete foundation leveling operations in conjunction with the concrete construction process. Simultaneously, the relative angle between the two leveling conveyor belts 6 can be adjusted as needed during operation, enabling flexible adaptation of the leveling width per pass. This effectively improves the adaptability of the leveling operation to different scenarios and allows for flexible adjustment of leveling parameters. Both the first conveyor frame 3 and the second conveyor frame 4 are equipped with second servo motors 8, and smoothing mechanisms are installed outside both the first conveyor frame 3 and the second conveyor frame 4. The two second servo motors 8 are used to drive the movement of the two leveling conveyor belts 6. Drive pulleys 19 and driven pulleys 20 are installed inside both the first conveyor frame 3 and the second conveyor frame 4. The two leveling conveyor belts 6 are respectively connected to the two drive pulleys 19 for transmission. The conveyor belt 6 is connected to two driven pulleys 20. The output shafts of the two second servo motors 8 are connected to the linkage shafts 21 inside the two drive pulleys 19. The two second servo motors 8 are also used to drive the two smoothing mechanisms. Both smoothing mechanisms include an outer frame 22 and a transmission turntable 23. The two outer frames 22 are fixedly connected to the first conveyor frame 3 and the second conveyor frame 4, respectively. An outer smoothing plate 24, a middle smoothing plate 25, and an inner smoothing plate 26 are slidably connected inside the two outer frames 22. A transmission vertical sleeve 27 is fixedly connected to the top of each of the two inner smoothing plates 26. A transmission rod 28 is connected inside each of the two transmission vertical sleeves 27. The two transmission rods 28 are fixedly connected to the two transmission turntables 23, respectively. The two transmission turntables 23 are fixedly connected to the two drive pulleys 24 and 25, respectively. The linkage shaft 21 is fixedly connected. Two intermediate screed plates 25 and two outer screed plates 24 are each fixedly connected to a transmission rack 29. Two inner screed plates 26 and two intermediate screed plates 25 are each fixedly connected to a drive rack 30. All four transmission racks 29 are meshed with linkage gears 31. The four drive racks 30 mesh with the four linkage gears 31 respectively. Two gear shafts 32 are fixedly connected inside each of the two outer frames 22. The four linkage gears 31 are rotatably connected to the four gear shafts 32 respectively. Through the design of the smoothing mechanism, auxiliary smoothing treatment can be performed on the concrete after it has been leveled by the leveling conveyor belt 6. This significantly optimizes the surface forming quality of the concrete, ensures that the concrete slope protection achieves a complete forming effect, and meets the construction quality standards of the slope protection project.The outer trowel 24, the middle trowel 25, and the inner trowel 26 are all equipped with double-sided slopes 54. The outer trowel 24 and the inner trowel 26 each have a feed slope 55 at their far ends, facilitating relative insertion with the concrete during movement.

[0041] Furthermore, the synchronous adjustment assembly is equipped with a double-sided limiting structure. Both the first conveyor frame 3 and the second conveyor frame 4 are connected to the double-sided limiting structure. The double-sided limiting structure includes a first side limiting frame 33 and a second side limiting frame 34. A first connecting shaft 35 and a second connecting shaft 36 are respectively installed on the first side limiting frame 33 and the second side limiting frame 34. Both the first connecting shaft 35 and the second connecting shaft 36 are slidably connected to a sliding sleeve frame 37. Both sliding sleeve frames 37 are fixedly connected to telescopic bending rods 38. Both telescopic bending rods 38 are slidably connected to fixed mounting cylinders 39. Both fixed mounting cylinders 39 are fixedly connected to intermediate mounting frames 40. The two intermediate mounting frames 40 are rotatably connected to the first following bending frame 11 and the second following bending frame 12, respectively. The first and second drive bending frames 14 and 15 are rotatably connected to each other. Both the first and second side limiting frames 33 and 34 are fixedly connected to portal-shaped rods 41. Each portal-shaped rod 41 has a connecting shaft section 42. Both the first and second conveying frames 3 and 4 are fixedly connected to guide sleeves 43, which are respectively fitted over the two connecting shaft sections 42. Through the design of the double-sided limiting structure, precise boundary definition can be achieved for the concrete to be constructed, ensuring that concrete leveling and smoothing operations are always carried out in an orderly manner within the preset construction area. This avoids construction deviations caused by boundary offsets, improves the accuracy and standardization of construction, and achieves precise control of the work area. The first connecting shaft 35 and the second connecting shaft 36 are both fixedly connected to the first half-rod head 44 and... The second half-pole head 45, the first side limiting bracket 33, and the second side limiting bracket 34 are all provided with a first positioning groove 46 and a second positioning groove 47. The two first half-pole heads 44 are respectively positioned in the two first positioning grooves 46, and the two second half-pole heads 45 are respectively positioned in the two second positioning grooves 47. A first positioning pressure bracket 48 is fixedly connected to each of the two first positioning grooves 46, and the two first positioning pressure brackets 48 are respectively matched with the two first half-pole heads 44. A second positioning pressure bracket 49 is fixedly connected to each of the two second positioning grooves 47, and the two second positioning pressure brackets 49 are respectively matched with the two second half-pole heads 45. This achieves a corresponding installation structure for the first connecting shaft 35 and the second connecting shaft 36, facilitating the manufacturing and assembly of the corresponding structure. Both the first side limiting frame 33 and the second side limiting frame 34 are provided with double-sided chamfered corners 59. When the first side limiting frame 33 and the second side limiting frame 34 move relative to the concrete, the double-sided chamfered corners 59 can be matched with the concrete to form a lateral drive, so as to facilitate the concentrated drive of the scattered concrete on the side. Both sides of the moving frame 1 are fixedly connected with rotating ring seats 60. The first follower bending frame 11 and the second follower bending frame 12 are rotatably connected to the two rotating ring seats 60 respectively. The first follower bending frame 11 is longer than the second follower bending frame 12, the first drive bending frame 14 is longer than the second drive bending frame 15, and the first side limiting frame 33 is longer than the second side limiting frame 34, which provides structural convenience for the staggered installation of the first conveying frame 3 and the second conveying frame 4. A counterweight stabilizing frame is installed at the rear end of the moving frame 1.Two bogies 61 are mounted on the counterweight stabilizing frame, and each bogie 61 is equipped with a steering wheel 62. The two steering wheels 62 and the powered track 2 inside the moving frame 1 are arranged in a triangular pattern, which improves the stability of the moving frame 1 relative to the ground and ensures the safe movement of the moving frame 1.

[0042] The first servo motor, the second servo motor, and the electric telescopic rod in this embodiment are all commercially available conventional devices known to those skilled in the art. In this invention, we simply use them without making any improvements to their structure or function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. Therefore, we will not elaborate on them here.

[0043] In summary, the working principle of this concrete leveling device for riverbank protection in water conservancy projects is as follows: Before use, a battery is first installed inside the mobile frame 1 to power the track 2, serving as the power supply component for its operation. Simultaneously, a central controller is installed inside the mobile frame 1, connecting the first servo motor 5, two second servo motors 8, and two electric telescopic rods 10 to the battery and central controller. The battery provides power to these components, while the central controller controls their operation. This process clears unnecessary debris and gravel from the riverbank protection area, marks the construction boundary, and ensures... The construction area is flat and free of obstacles, providing a basic condition for the movement and operation of the concrete leveling device for the riverbank protection of this water conservancy project. The power system corresponding to the control track 2 is powered on and activated, driving the concrete leveling device to the construction area. During movement, the steering wheel 62 can be used to adjust the orientation of the moving frame 1. In the moving state, the retraction of the actuator rod is controlled by the coordinated operation of two electric telescopic rods 10. The operation of the electric telescopic rods 10 enables the linkage of the drive linkage installed on its actuator rod. The movement of the drive linkage drives the corresponding synchronous shaft 9 to rotate relative to the fixed inner support 13. Therefore, the coordinated operation of the two electric telescopic rods 10 enables the coordinated rotation of the two synchronous shafts 9. The two synchronous shafts 9 rotate in combination to form the linkage rotation of the first drive bending frame 14 and the second drive bending frame 15. Since the first drive bending frame 14 and the second drive bending frame 15 are respectively rotatably connected to the two side mounting frames 16, and the two side mounting frames 16 are respectively rotatably connected to the sliding frame 17 and the adapter frame 18, and the first follower bending frame 11 and the second follower bending frame 12 are respectively rotatably mounted on both sides of the movable frame 1 through two rotating ring seats 60 and linked with the side mounting frames 16, the rotation of the first drive bending frame 14 and the second drive bending frame 15 will drive the two side mounting frames 16 to move in linkage. Therefore, when the first drive bending frame 14 and the second drive bending frame 15 are controlled to rotate and rise in combination, the coordinated movement of the two side mounting frames 16 can be achieved, ultimately realizing the leveling of the structure. When the working surface is raised, the two intermediate mounting frames 40 also rise as the first drive bending frame 14 and the second drive bending frame 15 rotate and rise together. Therefore, through the combined transmission action of the fixed mounting cylinder 39 and the telescopic bending rod 38, the double-sided limiting structure can be raised relative to the working surface. This facilitates the overall movement and position adjustment of the concrete leveling device for the riverbank protection of the water conservancy project. During the raising process of the leveling structure and the double-sided limiting structure, because the rotational raising diameter of the leveling structure is larger than that of the double-sided limiting structure, and the rotation radius of the leveling structure is larger than that of the double-sided limiting structure, the height of the leveling structure in the raised state is higher than that of the double-sided limiting structure. This avoids interference between the leveling structure and the double-sided limiting structure, and also prevents interference when the moving frame moves.The leveling structure and the double-sided limiting structure interfere with the ground.

[0044] After adjustment, the leveling structure should be aligned with the starting position of construction. The steering wheel 62 and the powered track 2 should be adjusted to form an equilateral triangular support distribution to ensure that the concrete leveling device for the riverbank protection of the water conservancy project travels in a straight line on the working surface when the powered track 2 moves. After adjustment, confirm that the moving frame 1 has no tendency to slide laterally on the slope. If the slope of the working surface is large and the moving frame 1 shows a tendency to slide laterally on the slope, lateral traction can be added at a higher position of the concrete leveling device for the riverbank protection of the water conservancy project, as shown in the attached diagram. Figure 16 As shown, a lateral traction rope is connected to its right side. A counterweight vehicle is placed at the top of the slope of the water conservancy river channel engineering slope, connecting the lateral traction rope to the counterweight vehicle to control the mobile frame 1 from lateral sliding or offset on the working surface. The arrow indicates the direction of travel of the mobile frame 1. Based on the required width of the working surface, two electric telescopic rods 10 are activated. The actuators of the two electric telescopic rods 10 extend and drive two synchronous shafts 9 to rotate within the fixed inner support 13. The two synchronous shafts 9 drive the first drive bending frame 14 and the second drive bending frame 15 to rotate synchronously and collaboratively. Finally, the leveling structure and the double-sided limiting structure are lowered together. During the lowering process, because the height of the leveling structure is higher than that of the double-sided limiting structure at any given time, the double-sided limiting structure will fall together with the leveling structure. That is, the leveling structure will land on the double-sided limiting structure at the same time as the double-sided limiting structure. Due to the sliding connection between the sliding frame 17 and the first conveyor frame 3 and the fixed connection between the adapter frame 18 and the second conveyor frame 4, the first servo is activated. When the output shaft of the first servo motor 5 drives the first conveyor frame 3 to rotate via the rotating cylinder 58 on the extension frame 57, the rotating cylinder 58 is rotatably connected to the cantilever frame 56, thereby driving the first conveyor frame 3 to rotate relative to the second conveyor frame 4. This fine-tunes the relative angle between the two leveling conveyor belts 6. During the adjustment process, the leveling width needs to be calibrated through the boundary line of the construction area to ensure compatibility. Furthermore, when there is a change in the relative angle between the first conveyor frame 3 and the second conveyor frame 4, the sliding frame 17 will form a relative sliding adjustment relative to the first conveyor frame 3 to make the first conveyor... The relative position between the first conveyor frame 3 and the second conveyor frame 4 can be adaptively adjusted. During the process of the relative angle change between the first conveyor frame 3 and the second conveyor frame 4, the connection between the connecting shaft section 42 and the guide sleeve 43 will drive the double-sided limiting structure to move together, so that the relative distance between the two portal rods 41 will be adjusted accordingly, thereby achieving the corresponding adjustment of the distance between the first side limiting frame 33 and the second side limiting frame 34, so that the relative distance between the first side limiting frame 33 and the second side limiting frame 34 can be adapted to the distance between the two leveling conveyor belts 6.

[0045] During leveling operations, two second servo motors 8 are activated. The output shafts of the two second servo motors 8 drive two linkage shafts 21 to rotate, which in turn drive two drive pulleys 19 to rotate. The drive pulleys 19 drive the driven pulleys 20 to rotate synchronously via the leveling conveyor belt 6. The initial operating speed of the leveling conveyor belt 6 is preset, and it is recommended that the operating speed of the leveling conveyor belt 6 be adjusted according to the concrete slump, generally controlled between 0.5 m / s and 1 m / s. The speed calibration function of the central controller ensures that the two leveling conveyor belts 6 operate synchronously. A special external concrete spreading device is used to evenly spread the concrete to the area to be constructed. In actual operation, the travel speed of the mobile frame 1 can be used to achieve the desired concrete speed. Following the concrete placement, and to avoid the impact of the moving track 2 on the concrete, the unobstructed space between the mobile frame 1 and the two leveling conveyor belts 6 can be selected as the placement position. This placement position should be one where the moving track 2 has already passed and the two leveling conveyor belts 6 are about to pass, meaning the area has been compacted by the moving track and the leveling conveyor belts can immediately cover it. During placement, the concrete thickness should be slightly higher than the design thickness to allow for leveling and avoid local accumulation or gaps. The power system within the mobile frame 1 is activated, controlling the moving track 2 to move slowly and uniformly. A speed of 0.2 m / min to 0.3 m / min is recommended for the moving track 2. Multiple actuating plates 7 on the leveling conveyor belts 6 rotate with the leveling conveyor belts 6, affecting the concrete. Preliminary paving and leveling are performed to distribute the accumulated concrete to a preset thickness, ensuring uniform concrete distribution. While the leveling conveyor belt 6 levels the foundation, the output shaft of the second servo motor 8 drives the transmission turntable 23 to rotate via the linkage shaft 21. The transmission turntable 23 drives the transmission rod 28 to perform circular motion. The transmission rod 28 drives the inner trowel plate 26 to reciprocate within the outer frame 22 via the transmission vertical sleeve 27. The drive rack 30 on the inner trowel plate 26 drives the corresponding linkage gear 31 to rotate on the gear shaft 32. This rotating linkage gear 31 drives the transmission rack 29 on the middle trowel plate 25 to move, causing the middle trowel plate 25 to slide synchronously relative to the inner trowel plate 26. Similarly, the drive rack 30 on the middle trowel plate 25... The corresponding linkage gear 31 is driven to rotate, and the rotation of the linkage gear 31 drives the transmission rack 29 on the outer trowel plate 24 to move, ultimately realizing the coordinated reciprocating motion of the outer trowel plate 24, the middle trowel plate 25 and the inner trowel plate 26. The coordinated reciprocating motion of the outer trowel plate 24, the middle trowel plate 25 and the inner trowel plate 26 performs secondary smoothing treatment on the concrete after it has been leveled by the leveling conveyor belt 6. Since the outer trowel plate 24, the middle trowel plate 25 and the inner trowel plate 26 are all equipped with double-sided slopes 54, and the feed slopes 55 of the outer trowel plate 24 and the inner trowel plate 26 at opposite ends are adapted to the direction of equipment travel, it is convenient to cut smoothly into the concrete surface, eliminate the traces of the agitator plate 7, compact the concrete surface, and improve the forming quality of the concrete surface.

[0046] During operation, the powered track 2 moves the mobile frame 1. The counterweight stabilizing frame, bogie 61, and steering wheels 62 work together to stabilize and support the mobile frame 1. The bogie 61 can be adjusted relative to the counterweight stabilizing frame to change the direction of the mobile frame 1, thus enabling continuous concrete leveling. The construction status is monitored in real time, with a focus on observing the surface flatness of the concrete after passing through the outer frame 22. To facilitate quantitative testing of flatness, a 2-meter straightedge can be used for phased sampling. The boundary of the double-sided limiting structure effectively prevents concrete from overflowing into the preset construction area. The stability of the concrete leveling device for the riverbank protection is checked in real time to ensure that the counterweight stabilizing frame does not shake and the powered track 2 does not slip, preventing overall equipment displacement during operation. After the construction of one area is completed, the concrete placement is stopped, and the concrete leveling device for the riverbank protection continues to move a certain distance to ensure that the leveling conveyor belt 6 and the smoothing mechanism complete the leveling and smoothing of the remaining concrete. After leveling the surface, shut down the second servo motor 8 and the power system inside the moving frame 1. Then, drive the synchronous adjustment component through the electric telescopic rod 10 to control the lifting of the leveling mechanism and the double-sided limit structure. After the leveling mechanism and the double-sided limit structure are lifted, adjust the position of the moving frame 1 relative to the working surface. After the moving frame 1 is in place relative to the new working surface, repeat the above operation process to continue the operation. After all construction areas are completed and the moving frame 1 is moved to the temporary storage area, shut down the first servo motor 5, the second servo motor 8, the electric telescopic rod 10 and the power system inside the moving frame 1 in sequence, and cut off the overall main power supply. If the equipment is not used for a long time, it should be cleaned and maintained as necessary. Clean the concrete residue on the leveling conveyor belt 6, rinse the outer trowel 24, the middle trowel 25 and the inner trowel 26 with clean water to remove the concrete attached to the surfaces of the three, clean the impurities on the power track 2 and the steering wheel 62, check the lubrication of each moving part, and add matching lubricating oil to the corresponding moving parts if necessary.
