Description

Technical Field

[0001] This invention relates to the field of slope protection technology, specifically to a slope protection paving device and method. Background Technology

[0002] During the construction of water conservancy projects, slope protection works are required on both sides of the river to prevent riverbed collapse. This strengthens the riverbanks, enabling them to withstand the impact of strong water flows during the flood season and preventing slope collapse. Conventional slope protection works use slope protection bricks for paving, and vegetation can be planted between the bricks to form an ecological slope protection system. This not only enhances the strength of the slope protection but also improves its aesthetics.

[0003] Chinese utility model patent with authorization announcement number CN216510955U discloses a riverbank protection laying device for water conservancy projects. The device solves the problem of consumables scattering due to vibration of the conveyor box during the sliding process by setting a fixing component to press and fix the cover plate on the consumables inside the conveyor box. The device also solves the problem of consumables breaking when the conveyor box vibrates during the sliding process by setting a buffer component to cancel the kinetic energy of the conveyor box when the spring deforms. This allows the conveyor box to stop more smoothly, solving the problem of the bearing rod and the bottom block breaking when the conveyor box collides with the blocking block.

[0004] The aforementioned devices only facilitate the transportation of paving materials; manual paving of the slope is still required, resulting in low paving efficiency. Furthermore, since riverbank protection slopes are mostly steep slopes, the working conditions for construction workers are somewhat risky. Therefore, the equipment and methods for paving slope protection bricks still need improvement. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a laying device and method for automatically laying slope protection bricks.

[0006] This invention provides a slope protection laying device, including a first conveying mechanism disposed at the top of a slope and a second conveying mechanism disposed on the slope. Both the first and second conveying mechanisms have rollers at their bottoms for movement. The first conveying mechanism includes a belt conveyor for conveying square slope protection material to the second conveying mechanism. The second conveying mechanism includes a first rotating shaft disposed at the top of the slope and a second rotating shaft disposed at the bottom of the slope, as well as two first limiting plates located on both sides of the belt conveyor. The distance between the two first limiting plates is equal to the width of the slope protection material. The two ends of the first limiting plates are respectively disposed on the first and second rotating shafts. Two pairs of sprockets are disposed on the first and second rotating shafts, respectively, and the two pairs of sprockets are respectively disposed outside the two first limiting plates. A chain is wound around the sprockets, and a support member for supporting the slope protection material is disposed around the outer periphery of the chain. The length of the support member is equal to the distance between the first and second rotating shafts. A baffle perpendicular to the first limiting plates is disposed between the two first limiting plates near the second rotating shaft.

[0007] Furthermore, the first conveying mechanism includes a feeding box, the belt conveyor is disposed inside the feeding box, the belt conveyor includes a third rotating shaft and a fourth rotating shaft, both of which are provided with pulleys, and belts are wound around the pulleys, and the first rotating shaft and the fourth rotating shaft are the same rotating shaft.

[0008] Furthermore, two support members are provided, each located on the chain of one pair of sprockets, and the width of the two support members is less than the distance between the first limiting plate and the pulley.

[0009] Furthermore, the support member includes multiple support plates along its length, the support plates are parallel to the chain, the support plates are connected to the chain through connecting blocks, and one end of the support plate extends inward toward the first limiting plate.

[0010] Furthermore, the second conveying mechanism includes two second limiting plates parallel to the first limiting plate. The two ends of the second limiting plates are respectively disposed on the first rotating shaft and the second rotating shaft. The second limiting plates are arranged on the outside of the sprocket. A first sensor and a second sensor are disposed on the end face of the second limiting plate near the slope. The first sensor and the second sensor are respectively disposed directly below the first rotating shaft and the second rotating shaft. The first sensor and the second sensor are used to detect whether there is a support at their position.

[0011] Furthermore, the belt conveyor is driven by a first servo motor, the sprocket is driven by a second servo motor, and the slope protection laying device includes a controller for controlling the switching of the first servo motor and the second servo motor. The controller is connected to a first sensor and a second sensor, and the controller can only start the first servo motor when it receives signals from both the first sensor and the second sensor simultaneously.

[0012] Furthermore, the roller is connected to the first conveying mechanism and the second conveying mechanism via a telescopic rod.

[0013] The present invention also provides a method for laying slope protection, comprising the following steps:

[0014] S1. The second servo motor drives the chain to rotate until the support is fully rotated to the side of the first limit plate near the slope.

[0015] S2. The first servo motor drives the belt conveyor to transport the square slope protection material to the support component until the support component is covered with slope protection material.

[0016] S3. The second servo motor drives the chain to rotate, and the slope protection material on the support falls sequentially from the end away from the belt conveyor to the end near the belt conveyor at the pre-laying position on the slope, completing the laying operation of one slope protection.

[0017] Furthermore, in step S1, the support member is determined to be fully rotated to the side of the first limiting plate near the slope by detecting signals from both the first sensor and the second sensor.

[0018] Furthermore, step S1 includes adjusting the overall height of the second conveying mechanism by means of a telescopic rod to reduce the distance between the second conveying mechanism and the slope.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention, by setting a rotatable support component, can support and lay the paving material, realizing automatic paving of the paving material without manual intervention, thus improving paving efficiency.

[0021] 2. The present invention facilitates accurate positioning of the support component by setting a first sensor and a second sensor, eliminating the need for manual observation and improving laying efficiency.

[0022] 3. The present invention rotatably connects the second conveying mechanism to the first conveying mechanism through the first rotating shaft, and the second conveying mechanism can be directly arranged along the slope inclination direction so that the swing arm is parallel to the slope, which is convenient for laying.

[0023] 4. The distance between the two first limiting plates of the present invention is equal to the width of the slope protection material, which can ensure that the slope protection material is still neatly arranged in a row after being transported to the support, thus ensuring the quality of the laying.

[0024] 5. The second conveying mechanism of the present invention shares a rotating shaft with the first conveying mechanism, and there will be no misalignment or tilt between the second conveying mechanism and the first conveying mechanism, so that the slope protection material transported by the conveyor belt can be accurately delivered to the support of the second conveying mechanism.

[0025] 6. The present invention places the support member between the first limiting plate and the belt conveyor, ensuring that the rotation between the limiting member and the conveyor belt will not interfere. Attached Figure Description

Detailed Implementation

[0033] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0034] like Figures 1 to 3As shown, a slope protection laying device includes a first conveying mechanism set at the top of the slope and a second conveying mechanism set on the slope. Both the first and second conveying mechanisms have rollers at their bottoms for movement. The first conveying mechanism includes a belt conveyor for conveying square slope protection material to the second conveying mechanism. The second conveying mechanism includes a first rotating shaft 3 set at the top of the slope, a second rotating shaft 4 set at the bottom of the slope, and two first limiting plates 2 located on both sides of the belt conveyor. The distance between the two first limiting plates 2 is equal to the width of the slope protection material. The two ends of the first limiting plates 2 are respectively set on the first rotating shaft 3 and the second rotating shaft 4. Two pairs of sprockets 5 are set on the first rotating shaft 3 and the second rotating shaft 4, respectively. The two pairs of sprockets 5 are respectively set on the outer sides of the two first limiting plates 2. A chain 6 is wound around the sprockets 5. A support member 7 for supporting the slope protection material is set on the outer periphery of the chain 6. The length of the support member 7 is equal to the distance between the first rotating shaft 3 and the second rotating shaft 4. A baffle 10 perpendicular to the first limiting plates 2 is set between the two first limiting plates 2 near the second rotating shaft 4.

[0035] Specifically, the second conveying mechanism is parallel to the slope. The first and second conveying mechanisms can be two independent mechanisms that are not connected to each other or two mechanisms that are connected to each other. One end of the second conveying mechanism is set at the top of the slope via rollers, and the other end is set at the bottom of the slope via rollers. The first conveying mechanism is used to convey the slope protection material to the support member 7 of the second conveying mechanism. The second conveying mechanism lays the slope protection material on the slope through the rotation of the support member 7. The slope protection material is a square slope protection material, such as slope protection bricks.

[0036] Understandably, the first and second conveying mechanisms can be moved to the pre-laying position via rollers. The support member 7 is rotated to the side of the second conveying mechanism closest to the slope. Then, square slope protection material is placed on the first conveying mechanism, which automatically transports the material to the support member 7 of the second conveying mechanism. The material automatically slides to the baffle 10, where each subsequent piece blocks the next, forming a row of slope protection material. Once the support member 7 is fully covered with material, the sprocket 5 begins to rotate, controlling the rotation of the support member 7. Since the length of the support member 7 is equal to the distance between the first and second rotating shafts 3 and 4, the rotating support member 7 causes the slope protection material to lose its support and fall towards the slope one by one. Figure 1 The support member 7 rotates counterclockwise, causing the slope protection material to gradually fall and be laid from the bottom of the slope to the top.

[0037] In some embodiments, the first conveying mechanism includes a feeding box 1, the belt conveyor is disposed in the feeding box 1, the belt conveyor includes a third rotating shaft 11 and a fourth rotating shaft 12, both the third rotating shaft 11 and the fourth rotating shaft 12 are provided with pulleys 13, and belts 14 are wound on the pulleys 13, the first rotating shaft 3 and the fourth rotating shaft 12 are the same rotating shaft.

[0038] Specifically, both ends of the third rotating shaft 11 and the fourth rotating shaft 12 are rotatably connected to the feeding box 1. The first rotating shaft 3 or the fourth rotating shaft 12 is a fixed shaft and will not rotate. The pulley 13 on the third rotating shaft 11 is an integral structure with the third rotating shaft 11. The pulley 13 on the fourth rotating shaft 12 is rotatably connected to the fourth rotating shaft 12. By driving the third rotation of the belt conveyor, the belt 14 is driven to move. The pulley 13 on the fourth rotating shaft 12 will rotate on the fourth rotating shaft 12 as the belt 14 moves. The sprocket 5 on the second rotating shaft 4 is fixedly connected to the second rotating shaft 4. The sprocket 5 on the first rotating shaft 3 is rotatably connected to the first rotating shaft 3. By driving the second rotating shaft 4, the sprocket 5 is driven to rotate. The sprocket 5 drives the chain 6 to move. The chain 6 drives the sprocket 5 on the first rotating shaft 3 to rotate around the first rotating shaft 3. In addition, the first limiting plate 2 can also rotate around the first rotating shaft 3, so that the second conveying mechanism is suitable for slopes with various inclination angles.

[0039] Furthermore, there are two support members 7, which are respectively located on the chains 6 of the two pairs of sprockets 5. The width of the two support members 7 is less than the distance between the first limiting plate 2 and the pulley 13.

[0040] Since the first shaft 3 and the fourth shaft 12 are the same shaft, the pulley 13 will interfere with the movement of the support 7 on the chain 6. The distance between the first limiting plate 2 and the pulley 13 needs to be no less than the width of the support 7 so that the support 7 can move completely around the outer periphery of the second conveying mechanism to complete the laying operation. By setting two support 7, the two ends of the slope protection material will be supported by the two support 7.

[0041] The support member 7 includes multiple support plates 8 along its length. The support plates 8 are parallel to the chain 6 and are connected to the chain 6 via connecting blocks 9. One end of the support plate 8 extends inward toward the first limiting plate 2.

[0042] Since the support member 7 moves under the drive of the chain 6, if the support member 7 is a single rigid plate, the support member 7 cannot rotate at the sprocket 5. Setting the support member 7 as multiple independent support plates 8 can ensure that the support member 7 moves along the outer periphery of the second conveying mechanism as a whole.

[0043] It should be noted that when the first shaft 3 and the fourth shaft 12 are not the same shaft, the pulley 13 will not affect the movement of the support 7, and the support plate 8 can be a long strip plate structure with two chains 6 connected at both ends.

[0044] In some embodiments, as shown in 2, 4, and 5, the second conveying mechanism includes two second limiting plates 15 parallel to the first limiting plate 2. The two ends of the second limiting plates 15 are respectively disposed on the first rotating shaft 3 and the second rotating shaft 4. The second limiting plates 15 are arranged outside the sprocket 5. A first sensor 16 and a second sensor 17 are disposed on the end face of the second limiting plate 15 near the slope. The first sensor 16 and the second sensor 17 are respectively disposed directly below the first rotating shaft 3 and the second rotating shaft 4. The first sensor 16 and the second sensor 17 are used to detect whether there is a support member 7 at their positions.

[0045] Understandably, when both the first sensor 16 and the second sensor 17 receive signals, it indicates that the support member 7 is completely at the bottom of the second conveying mechanism, i.e., close to the slope. At this time, the slope protection material conveyed by the belt conveyor will fall directly onto the support member 7, ensuring that the slope protection material will not fall directly onto the slope. By setting the first sensor 16 and the second sensor 17, the position of the support member 7 can be accurately located without manual observation, thus improving the laying efficiency.

[0046] Furthermore, the belt conveyor is driven by a first servo motor 18, and the sprocket 5 is driven by a second servo motor 19. The slope protection laying device includes a controller 20 for controlling the switching of the first servo motor 18 and the second servo motor 19. The controller 20 is connected to a first sensor 16 and a second sensor 17. The controller 20 can only start the first servo motor 18 when it receives signals from both the first sensor 16 and the second sensor 17.

[0047] Understandably, the first sensor 16 and the second sensor 17 form a locking mechanism for the belt conveyor. Only when the support member 7 has moved completely to the bottom of the second conveying mechanism, i.e., the side of the second conveying mechanism close to the slope, can the worker start the first servo motor 18 to begin conveying the slope protection bricks. This can prevent the slope protection bricks from falling off between the two first limit plates 2 due to the support member 7 not being reset.

[0048] In some embodiments, the roller is connected to the first conveying mechanism and the second conveying mechanism via a telescopic rod 21.

[0049] It should be noted that in order to prevent damage and misalignment of the slope protection material after it falls, the distance between the support 7 and the slope surface should be minimized as much as possible to ensure the laying effect. The height of the first and second conveying mechanisms can be adjusted by setting the structure connected to the roller as an adjustable-length telescopic rod 21.

[0050] Specifically, the telescopic rod 21 includes a sleeve and a rack. The sleeve has an opening at the top and is connected to a roller at the bottom. One end of the rack is inserted into the sleeve, and the other end is connected to the second limiting plate 15. The rack is slidably connected to the sleeve. A gear that meshes with the rack is provided inside the sleeve. The gear is mounted on a fifth rotating shaft. One end of the fifth rotating shaft is rotatably connected to the inner wall of the sleeve, and the other end extends out of the sleeve and is equipped with a knob. The raising and lowering of the rack can be controlled by manually rotating the knob, thereby controlling the height of the first conveying mechanism and the second conveying mechanism, thus ensuring that the slope protection bricks falling on the slope are neatly arranged.

[0051] The method for laying the above-mentioned slope protection laying device includes the following steps:

[0052] S1. The second servo motor 19 drives the chain 6 to rotate until the support 7 rotates completely to the side of the first limiting plate 2 near the slope.

[0053] Specifically, the second servo motor 19 drives the second rotating shaft 4 to rotate, thereby driving the chain 6 to rotate so that the support 7 rotates completely to the side of the first limiting plate 2 close to the slope. The first sensor 16 and the second sensor 17 both detect signals to determine that the support 7 has rotated completely to the side of the first limiting plate 2 close to the slope. The telescopic rod 21 adjusts the overall height of the second conveying mechanism to reduce the distance between the second conveying mechanism and the slope, so that the subsequent slope protection bricks will not break or tilt when they fall on the slope.

[0054] S2. The first servo motor 18 drives the belt conveyor to transport the square slope protection material to the support 7 until the support 7 is covered with slope protection material.

[0055] Specifically, square slope protection bricks are neatly placed on a belt conveyor by hand. The belt conveyor then transports the slope protection piles to the support member 7. Under the action of the first limiting plate 2, the slope protection bricks entering the second conveying mechanism will be neatly arranged. The slope protection bricks slide toward the baffle 10 in sequence until the support member 7 is covered with slope protection bricks.

[0056] S3. The second servo motor 19 drives the chain 6 to rotate, and the slope protection material on the support 7 falls sequentially from the end away from the belt conveyor to the end near the belt conveyor at the pre-laying position on the slope, completing the laying operation of one slope protection.

[0057] The working principle is as follows: The worker sets up the second conveyor on the slope, places the first conveyor at the top of the slope, and puts the slope protection bricks into the feed box 1; the worker starts the second servo motor 19 through the controller 20. The second servo motor 19 rotates and rotates the support plate 8 to below the first limit plate 2, so that the support plate 8 is fully distributed between the first sensor 16 and the second sensor 17; after the first sensor 16 and the second sensor 17 simultaneously detect the signal of the limit plate, the controller 20 can turn on the operation switch of the first servo motor 18. That is, the first sensor 16 and the second sensor 17 form the locking mechanism of the belt conveyor. When the first sensor 16 and the second sensor 17 both receive the signal, it means that the support plate 8 is completely below the first limit plate 2, which can support the slope protection bricks and prevent the slope protection bricks from falling off between the two first limit plates 2 due to the support plate 8 not being reset.

[0058] The first servo motor 18 drives the belt 14 to rotate, transferring the slope protection bricks on the surface of the belt 14 to the support plate 8. The slope protection bricks slide sequentially onto the baffle 10 until the support 7 is fully covered with slope protection bricks. The controller 20 controls the second servo motor 19 to rotate, causing the support plate 8 to rotate counterclockwise, so that the slope protection bricks fall sequentially to the laying position, completing the laying operation of one slope protection brick. After moving to the next laying position, the position of the support plate 8 is reset, and slope protection bricks are replenished to the second conveying mechanism again via the belt 14 for laying again.

[0059] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
