Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects and river bank protection, in particular to a mechanized system suitable for laying river bank protection bricks. Background Art

[0002] In river management and ecological restoration projects, paving riverbank slopes with concrete retaining bricks is a common protective measure. It effectively prevents soil erosion, stabilizes riverbanks, and maintains certain ecological functions. However, traditional methods of paving riverbank retaining bricks present significant efficiency and labor cost issues, especially when applied to sloping riverbanks with steep slopes and complex terrain.

[0003] Prior art relied primarily on manual labor to lay these large, heavy slope protection bricks. Because riverbank slopes typically have a certain inclination, and due to limitations such as soil bearing capacity and safety concerns, heavy transport vehicles and conventional construction machinery (such as cranes and loaders) often struggle to directly access or approach the sloped work area. Consequently, slope protection bricks can typically only be transported to the shore or the top of the slope, with subsequent transportation and laying processes relying entirely on manual labor. The specific process involves manually transporting the slope protection bricks from storage to designated locations on the slope, followed by alignment, laying, and adjustment. Each slope protection brick weighs a significant amount (ranging from tens to hundreds of kilograms), making transporting and precisely positioning them on the sloping surface extremely labor-intensive and leading to extremely low construction efficiency.

[0004] This purely manual operation mode leads to the following problems: (1) Huge labor consumption: a large number of workers are required for high-intensity transportation and laying; (2) Low construction efficiency: manual work is slow, which seriously restricts the progress of the project; (3) High safety risk in operations: Workers moving and working on slippery or steep slopes while carrying heavy loads are prone to accidents such as slips, falls, and muscle strains; (4) Paving accuracy is difficult to ensure: Bricks are easily damaged during manual handling, and it is difficult to ensure the flatness and uniformity of paving joints for a long time under high-intensity labor; (5) High cost: Huge manpower requirements and long construction period lead to high project construction costs.

[0005] While there are some auxiliary machines available on the market for laying small tiles on flat ground, there are few dedicated mechanical devices or systems that are efficient, cost-effective, and capable of continuous operation when laying large, heavy-duty slope protection bricks on sloping riverbanks. Therefore, there is an urgent need to develop a new type of mechanized slope protection brick laying system that can solve the challenges of handling, transporting, and laying heavy-duty slope protection bricks on sloping riverbanks, significantly reduce worker labor intensity, significantly improve construction efficiency, reduce safety risks and construction costs, and meet the needs of efficient construction of modern water conservancy projects.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. For ease of description, the direction toward the bank or the top of the slope is defined as the front, and the direction toward the bottom of the slope is defined as the rear.

[0024] like Figures 1 to 8 As shown, the present invention includes a track 2, a traction rope, a head end support device 1, a terminal support device 5 and a lifting device 3.

[0025] The track 2 has its head end located at the bank or top of a slope, its tail end located at the bottom of the slope, and its middle crossing the riverbank to be laid. The head end support device 1 and tail end support device 5 are located at the head end and tail end of the track 2, respectively, and the track 2 is raised to a certain height by the head end support device 1 and tail end support device 5.

[0026] The bases of the head end support device 1 and the tail end support device 5 are respectively provided with wheels 9 and a power device. According to the progress of paving, the power device drives the wheels 9 to make the whole structure move along the length direction of the river channel.

[0027] There are multiple lifting devices 3, each lifting device 3 lifts a slope protection brick 6, and transports each slope protection brick 6 to the laying position. Each lifting device 3 includes a walking mechanism 11, a lifting mechanism 15, a mechanical claw 14 and a connecting device. The walking mechanism 11 is matched with the track 2, and the lifting device 3 is moved along the track 2 by the walking mechanism 11. The mechanical claw 14 is matched with the slope protection brick 6 and can grab the slope protection brick 6. The lifting mechanism 15 is located between the walking mechanism 11 and the mechanical claw 14. The lifting mechanism 15 has an extension or telescopic function. The extension or telescopic movement of the lifting mechanism 15 causes the mechanical claw 14 to drive the slope protection brick 6 to descend or ascend. The walking mechanism 11, the lifting mechanism 15 and the mechanical claw 14 are connected as a whole by a connecting device.

[0028] There are two traction ropes: a limit rope 20 and a power rope 21. The limit rope 20 is fixed to each lifting device 3 and is used to limit the distance between two adjacent lifting devices 3. The head end of the limit rope 20 is fixed near the head end of the track 2. The positions of the limit rope 20's fixing points are adjusted so that each slope protection brick 6 is in the laid position after the limit rope 20 is pulled. The power rope 21 is fixed to the rearmost lifting device 3. A pulley 22 is provided at the rear end of the track 2, around which the power rope 21 passes. The two ends of the power rope 21 are located at the front end of the track 2. A power rope roller 7 driven by a motor 8 is provided at the front end of the track 2. The two ends of the power rope 21 are wound around the power rope roller 7 in opposite directions. The motor 8 drives the power rope roller 7 to rotate, which in turn drives each lifting device 3 on the track 2 through the power rope 21.

[0029] When the span of the track 2 is large, several brackets 4 can be set in the middle of the track 2 to support the middle of the track 2. Figure 7 As shown, the bracket 4 comprises four adjustable legs, allowing it to maintain an upright position on slopes of varying gradients. A hook is located at the top of the bracket 4, and a matching hook is located at a corresponding position on the track 2, supporting the track 2 through suspension. Support springs 10 are installed between the head support 1 and the end support 5 at each end of the track 2. Due to the action of the support springs 10, when the slope protection bricks 6 are installed on the track 2, the overall weight increases, causing the track 2 to descend. When the slope protection bricks 6 are removed, the overall weight decreases, and the support springs 10 pull or lift the track 2 upward. When the track 2 descends, the bracket 4 touches the ground, sharing some of the weight. When the track 2 rises, the bracket 4 rises off the ground. At this point, the slope protection bricks 6 on the track 2 have all been removed, indicating that a row of slope protection bricks 6 has been laid, and the entire structure needs to be moved to the next row of slope protection bricks 6. The support springs 10 lift the bracket 4 off the ground after laying, facilitating movement of the entire structure.

[0030] like Figure 4 As shown, the track 2 is an I-beam structure, wherein the flanges of the I-beam are placed horizontally and the web is placed vertically. The running mechanism 11 includes two rollers 18 and a frame 19. The two rollers 18 are located on the flanges on both sides of the web. The frame 19 connects the two rollers 18 to form a whole, together forming the running mechanism 11.

[0031] like Figure 4 、 5As shown in Figure 6, the lifting mechanism 15 includes a hoisting rope roller 12 and a hoisting spring 13. The hoisting rope roller 12 includes a rope roller, a controllable friction brake, and a spring spring. In its natural state, the rope roller is locked by the controllable friction brake, preventing it from rotating. By pulling the controllable friction brake control structure 16, the controllable friction brake is released, allowing the rope roller to rotate freely. The rope is released, allowing the slope protection bricks 6 to fall to the ground and be laid. The spring spring drives the rope roller to rotate in the opposite direction, retracting the rope and raising the mechanical claw 14. The spring spring's elastic force is less than the weight of the slope protection, so that the mechanical claw 14 can only rise after the slope protection bricks 6 are removed.

[0032] The function of the lifting spring 13 is to facilitate the adjustment of the position of the slope protection brick 6. When the slope protection brick 6 lands, the position may not be accurate. When the position of the slope protection brick 6 needs to be further adjusted, the slope protection brick 6 needs to be lifted. When the slope protection brick 6 first lands, it can be placed in a semi-grounded state. The so-called semi-grounding means that the slope protection brick 6 stops releasing the rope roller when it touches the ground lightly. At this time, the lifting spring 13 is still in an extended state, and the lifting spring 13 still exerts an upward elastic tension on the slope protection brick 6, but this tension is less than the gravity of the slope protection brick 6. At this time, if the position of the slope protection brick 6 needs to be adjusted, the construction worker only needs to apply light force to cooperate with the spring tension to lift the slope protection brick 6 and readjust the position. When the position of the slope protection brick 6 is accurately adjusted, the rope roller is completely released, causing the lifting spring 13 to shorten and return to its original length. At this time, the mechanical claw 14 can be removed from the slope protection brick 6.

[0033] It should be noted that the specific embodiments of the present invention have been described in detail. For those skilled in the art, various obvious changes to it without departing from the spirit and scope of the present invention are within the scope of protection of the present invention.
