Description

Technical Field

[0001] This invention relates to the field of stone paving technology, and in particular to a device for directional paving of ground stone. Background Technology

[0002] In the field of building decoration construction, the laying of floor stone or large ceramic tiles is developing towards mechanization and intelligence. Currently, there are two main technical routes in the industry: one is highly integrated fully automatic laying robots, which can complete the entire process of construction from mortar spreading and slab grabbing to precise alignment and compaction in open areas through robotic arms, vision recognition and automatic control systems, significantly improving the efficiency and accuracy of large-scale laying; the other is the widely used semi-mechanized auxiliary tools, the most typical of which are various stone handling vehicles. These devices mainly solve the problem of transporting heavy slabs from the stacking area to the laying point through electric suction cups, forklifts or clamping mechanisms, effectively reducing the labor intensity of workers.

[0003] However, the aforementioned fully automated equipment is typically bulky, expensive, and requires ample workspace, making it unsuitable for confined construction environments. In these small spaces, the current common practice is for construction workers to first rely on single-function stone transport vehicles to move the slabs to their approximate location, followed by manual labor for precise alignment, leveling, gap adjustment, and manual compaction—the entire paving process. This approach presents the following pressing technical problems: 1. Paving equipment or transport vehicles often use the pre-laid stone as a path. The weight of the equipment and the downward pressure during operation directly and repeatedly act on these newly laid stones that have not yet reached their final strength, easily leading to uneven plastic settlement or displacement. This interference introduced by the construction process itself directly damages the flatness of the already worked surface, creating a vicious cycle of quality loss as the paving progresses. Furthermore, when paving adjacent areas, vibrations and impacts generated by equipment operation and material placement are transmitted through the base layer and disturb the already laid adjacent stones, causing displacement or warping.

[0004] 2. To adapt to narrow spaces, only small equipment with single functions, such as forklifts that can only be used, are usually available. This leads to the core processes of tiling, such as turning, alignment, leveling and compaction, being broken down and completely degenerated into manual labor. This results in cumbersome and inefficient work processes, and the final quality depends entirely on the skills and physical strength of the workers, making it impossible to achieve standardized and high-precision construction.

[0005] Therefore, the continuous damage to the already worked surface during the construction process and the difficulty in balancing the efficiency and accuracy of paving operations in narrow spaces are technical problems that need to be solved by those skilled in the art. Summary of the Invention

[0006] In view of the above problems, the present invention provides a ground stone directional laying device to solve the aforementioned technical problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a ground stone directional paving device, including a fixing frame, the bottom of which is provided with a plurality of electric suction cups for adsorbing and fixing onto the paved stone.

[0008] The support plate is slidably installed on the upper end of the fixed frame. The support plate has a concave structure, and the fixed frame is provided with a transmission part for driving the support plate to move along the length of the fixed frame.

[0009] The ramp is installed at an angle, with one end extending to the ground and the other end fixed to the bracket.

[0011] The rotating pick-and-place unit is mounted on the support plate and includes two electric suction cups for sequentially adsorbing the stones carried by the transport vehicle, and a drive unit for driving the electric suction cups to move and rotate.

[0012] The pressure roller is located below the support plate, which has a pushing part for driving the pressure roller to move downward to compact the laid stone.

[0013] The fixing part, set on the fixing frame, is used to attach and fix two adjacent stone pieces together after they have been laid.

[0014] The rotating pick-and-place unit grabs a single stone from the transport vehicle, adjusts its direction by rotation, moves it horizontally to the target position, lays it, and compacts it with a pressure roller. After adjacent stones are laid, the fixing unit adsorbs and connects them and locks them with the fixing frame to constrain their relative displacement.

[0015] As a preferred embodiment, the mounting bracket includes a rectangular frame, with bases fixedly mounted on the lower ends of the left and right sides of the rectangular frame via support columns, and multiple electric suction cups evenly fixedly mounted on the lower ends of the bases.

The telescopic section of the hydraulic cylinder slides through the fixing seat and then a connecting plate is fixedly installed. Two electric suction cups are fixedly installed at the lower end of the connecting plate. Support columns are slidably installed on both the left and right sides of the fixing seat. The lower end of the support column is fixedly connected to the upper end of the connecting plate.

[0017] As a preferred embodiment, the drive unit includes a top plate, a support plate with a fixed column at the upper end of the top plate, a waist groove on the top plate, a bottom plate slidably mounted on the upper end of the top plate, a hydraulic cylinder II fixedly mounted on the upper end of the bottom plate, the hydraulic cylinder II slidingly passing through the bottom plate and the waist groove and then fixedly mounted on a fixed plate, a rotating platform fixedly mounted on the lower end of the fixed plate, a support plate fixedly mounted on the rotating section at the lower end of the rotating platform, and multiple electric suction cups II evenly fixedly mounted on the lower end of the support plate.

[0018] As a preferred embodiment, the transport vehicle includes an L-shaped frame, with a handrail fixedly installed on the left side of the vertical section of the frame, and a pair of rollers and an arc-shaped plate concentric with the rollers rotatably installed at the lower end of the horizontal section of the frame.

[0019] As a preferred embodiment, the limiting part includes a stop block fixedly installed on the upper end of the support plate, the left end of the stop block is provided with an arc-shaped surface that fits with the roller, the upper end of the support plate is fixedly installed with a limiting block that fits with the concave surface of the arc-shaped plate, and the left end of the limiting block is fixedly installed with a hydraulic cylinder three with a telescopic section that passes through the limiting block and the arc-shaped plate.

[0020] As a preferred embodiment, the transmission unit includes two rotating shafts that are symmetrically mounted on the left and right sides and rotate between the two transverse sections of the rectangular frame. Two synchronous pulleys are fixedly mounted on the rotating shafts, and a transmission belt connects the two synchronous pulleys that are directly opposite each other on the left and right sides.

[0021] As a preferred embodiment, the pressing part includes a hydraulic cylinder four. The lower end of the support plate is fixedly installed with the hydraulic cylinder four via a support frame. The telescopic section of the hydraulic cylinder four slides through the support frame and is then fixedly installed with a bracket. The pressure roller is rotatably installed on the bracket.

[0022] As a preferred embodiment, a servo motor is fixedly mounted on the lower end of the rectangular frame via a motor mount. The output shaft of the servo motor is connected to the rotating shaft via a belt drive. A connecting seat is fixedly mounted on the belt, and the upper end of the connecting seat is fixedly connected to the support plate.

[0023] As a preferred embodiment, a lead screw is rotatably mounted on the upper end of the top plate via a bearing seat, and a screw block is threaded onto the lead screw. The upper end of the screw block is fixedly connected to the lower end of the bottom plate. A second servo motor with an output shaft fixedly connected to the lead screw is also fixedly mounted on the upper end of the top plate.

[0024] The above-described one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects:

[0025] I. This invention provides an integrated paving device specifically designed for narrow spaces through the synergistic action of a fixed frame, a support plate, a rotating pick-and-place unit, a pressure roller, and a fixing unit. It solves the problems of crushing and damaging the already worked surface by construction equipment, transmitting construction disturbances, and low efficiency and loss of precision due to the single function of the equipment in the prior art. It integrates the core processes of material picking, turning, laying, compaction, and immediate stabilization into a continuous mechanized process, thereby achieving a simultaneous improvement in the quality and efficiency of paving operations in narrow spaces while ensuring that the already paved surface is not damaged.

[0026] Second, in this invention, both movement and load are transmitted through a fixed frame, completely avoiding the direct walking and crushing of heavy components such as support plates and transport vehicles on the laid stone. At the same time, the fixed part immediately adsorbs and locks adjacent stones into a whole connected to the fixed frame after laying, forming a local rigid structure, which effectively suppresses the transmission of construction vibration and impact disturbance. These two measures fundamentally block the dynamic damage path of the construction process to the already worked surface, ensuring the final flatness of the laid surface.

[0027] Third, this invention can automatically complete a series of continuous actions, including picking up a single stone from the transport vehicle, precisely rotating and turning it in the air, moving it along the fixed frame to the paving position, laying it down, and then rolling and compacting it. The highly integrated mechanized process replaces the discrete and time-consuming processes of handling, turning, aligning and compacting that are entirely dependent on manual labor in the traditional method, thereby greatly improving the standardization, continuity and overall efficiency of paving operations in narrow spaces.

[0028] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0037] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] like Figure 1 and Figure 2 As shown, a ground stone directional paving device includes a fixing frame 10, the bottom of which is provided with a plurality of electric suction cups 102 for adsorbing and fixing onto the paved stone.

[0039] like Figure 1 and Figure 2 As shown, the support plate 11 is slidably mounted on the upper end of the fixed frame 10. The support plate 11 has a concave structure. The fixed frame 10 is provided with a transmission part 3 for driving the support plate 11 to move along the length direction of the fixed frame 10.

[0040] like Figure 1 As shown, the slope plate 12 is inclined, with one end extending to the ground and the other end fixed to the fixing frame 10.

[0041] likeFigure 1 As shown, the transport vehicle 13 is capable of carrying stacked stones and moving them along the slope 12 to the support plate 11. The support plate 11 is provided with a limiting part 4 for fixing the transport vehicle 13.

[0042] like Figure 1 and Figure 2 As shown, the rotating pick-and-place unit 15 is disposed on the support plate 11 and includes an electric suction cup 2 150 for sequentially adsorbing the stone materials carried by the transport vehicle 13, and a drive unit 2 for driving the electric suction cup 2 150 to move and rotate.

[0043] like Figure 1 and Figure 2 As shown, the pressure roller 14 is located below the support plate 11, and the support plate 11 is provided with a pushing part 5 for driving the pressure roller 14 to move downward to compact the laid stone.

[0044] like Figure 1 and Figure 2 As shown, the fixing part 6 is set on the fixing frame 10 and is used to adsorb and fix the two adjacent stones into one piece after they are laid.

[0045] like Figure 1 and Figure 2 As shown, the fixing frame 10 includes a rectangular frame 100, and a base 101 is fixedly installed on the lower ends of the left and right sides of the rectangular frame 100 through a support column. Multiple electric suction cups 102 are evenly fixedly installed on the lower ends of the base 101.

[0046] like Figure 1 , Figure 2 and Figure 4 As shown, the transport vehicle 13 includes an L-shaped frame 130, a handrail 131 is fixedly installed on the left side of the vertical section of the frame 130, and a pair of rollers 132 and an arc plate 133 concentric with the rollers 132 are rotatably installed at the lower end of the horizontal section of the frame 130.

[0047] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the limiting part 4 includes a stop block 40 fixedly installed on the upper end of the support plate 11. The left end of the stop block 40 is provided with an arc-shaped surface that fits against the roller 132. The upper end of the support plate 11 is fixedly installed with a limiting block 41 that fits against the concave surface of the arc plate 133. The left end of the limiting block 41 is fixedly installed with a hydraulic cylinder 42 with a telescopic section that passes through the limiting block 41 and the arc plate 133.

[0048] like Figures 1 to 5As shown, during the actual work, before the equipment enters the site, the foundation surface (i.e. the original foundation) of the construction area has been manually compacted and leveled to meet the paving requirements; at the same time, the starting and ending positions of the operation have been manually laid and solidified as the initial anchor points of the equipment, and the right side of the starting position has also been laid and solidified with stone.

[0049] When the device is started, it first firmly attaches itself to the manually laid stone slab that has reached stable strength via the electric suction cup 102 at the bottom of the base 101, thus constructing itself into a stable bridge-like platform spanning the area to be constructed. Then, a specially designed transport vehicle 13 is placed on its platform, which can stack multiple stones to be laid. The operator presses down on the handrail 131 to lift the curved plate 133 off the ground, and then pushes the transport vehicle 13 along the slope 12 onto the support plate 11, so that the transport vehicle... 13 moves along the inclined ramp 12 connected to the ground to the support plate 11, so that the roller 132 fits against the arc surface of the stop block 40. Then, the pressure on the handrail 131 is slowly released, and the arc plate 133 moves down to fit against the upper end of the support plate 11. At the same time, the concave surface of the arc plate 133 fits against the limit block 41 to restrict the left and right movement of the transport vehicle 13. Then, the telescopic section of the hydraulic cylinder 42 passes through the arc plate 133 to restrict the up and down and forward and backward movement of the transport vehicle 13, thereby fixing the transport vehicle 13.

[0050] The rotating pick-and-place unit 15 on the device is activated, and its drive unit 2 drives the electric suction cup 150 to descend, accurately grabbing a stone from the top layer of the transport vehicle 13. It is then lifted and rotated 90 degrees in the air, changing the stone's length direction from front-to-back to left-to-right. Next, the drive unit 2 carries the suspended stone and, driven by the transmission unit 3, moves it directly above the target paving position. Subsequently, the drive unit 2 drives the electric suction cup 150 to descend. Once the top of the stone is below the fixing unit 6, the stone is rotated 90 degrees in the opposite direction to return to its original state. The single stone is then smoothly placed in the predetermined position. Immediately afterward, the pressure roller 14 presses down and, along with the movement of the support plate 11, rolls the newly laid stone, ensuring a tight fit between the stone and the prepared base surface below.

[0051] After an adjacent stone is picked up, rotated, transported, placed, and pressed firmly onto the base surface using the same process, the fixing part 6 on the device begins to work. The fixing part 6 adheres to the two adjacent already laid stones, temporarily connecting them into a single slab. This step effectively prevents minor disturbances to the laid area that might occur during subsequent laying cycles, ensuring the overall flatness of the paved surface. After completing the laying and fixing of one unit, the device releases its initial anchor point, moves to the other side, and re-attaches and fixes itself to the newly laid stone, using this as a new reference point to begin the next identical work cycle. This operation enables efficient, high-precision, and high-quality continuous mechanized laying operations within a confined space, starting from a manually pre-laid section.

[0052] In addition, the transport vehicle 13 can be used independently without the fixed frame 10, the support plate 11 and the rotating pick-and-place part 15. The operator can directly push the transport vehicle 13 with stacked stones to the target area, move it flexibly using its rollers 132, and control its direction and position through the handle 131. Then, the stone is manually removed from the transport vehicle 13 and the laying is completed. This mode omits the adsorption positioning, measurement and installation of the fixed frame 10 and the cycle process of the whole set of equipment. It only uses the portable transportation function of the transport vehicle 13 to realize the most basic material transportation and manual laying under extreme working conditions, ensuring the applicability of the solution in all scenarios and the flexibility of operation.

[0053] like Figure 1 , Figure 2 and Figure 4 As shown, the drive unit 2 includes a top plate 20. The top plate 20 is fixedly installed on the upper end of the support plate 11 by a fixing column. A waist groove is opened on the top plate 20. A bottom plate 21 is slidably installed on the upper end of the top plate 20. A hydraulic cylinder 22 is fixedly installed on the upper end of the bottom plate 21. The hydraulic cylinder 22 slides through the bottom plate 21 and the waist groove and is fixedly installed on a fixing plate 23. A rotating platform 24 is fixedly installed on the lower end of the fixing plate 23. A support plate 25 is fixedly installed on the rotating section at the lower end of the rotating platform 24. Multiple electric suction cups 150 are evenly fixedly installed on the lower end of the support plate 25.

[0054] like Figure 2 and Figure 4 As shown, a lead screw 26 is rotatably mounted on the upper end of the top plate 20 via a bearing seat. A screw block is threaded onto the lead screw 26. The upper end of the screw block is fixedly connected to the lower end of the bottom plate 21. A servo motor 27 with an output shaft fixedly connected to the lead screw 26 is also fixedly mounted on the upper end of the top plate 20.

[0055] like Figure 1 , Figure 2 and Figure 3As shown, the transmission unit 3 includes two rotating shafts 30 that are symmetrically mounted between two transverse segments of the rectangular frame 100. Two synchronous pulleys are fixedly mounted on the rotating shafts 30, and a transmission belt 31 is connected between the two synchronous pulleys that are directly opposite each other.

[0056] like Figure 3 As shown, a servo motor 32 is fixedly installed at the lower end of the rectangular frame 100 via a motor mount. The output shaft of the servo motor 32 is connected to the rotating shaft 30 via a belt 33. A connecting seat 34 is fixedly installed on the upper part of the transmission belt 31, and the upper end of the connecting seat 34 is fixedly connected to the support plate 11.

[0057] like Figures 1 to 4 As shown, during operation, servo motor 27 starts, driving the lead screw 26, which is fixed to its output shaft, to rotate. The screw block, which is threaded to the lead screw 26, moves axially along the lead screw 26. Because the upper end of the screw block is fixedly connected to the lower end of the base plate 21, the entire base plate 21 slides along the groove on the upper end of the top plate 20, causing the electric suction cup 150 to move directly above the stone carried by the transport vehicle 13. Then, the telescopic section of the hydraulic cylinder 22 extends, driving the fixed plate 23, which is fixedly connected to its lower end, to rotate. The turntable 24 and support plate 25 descend as a whole, causing the electric suction cup 2 150 to descend and make close contact with the surface of the topmost stone in the stack of stones on the transport vehicle 13. Then, the electric suction cup 2 150 is activated to firmly adsorb the stone. Next, the telescopic section of the hydraulic cylinder 2 22 retracts, vertically lifting the adsorbed stone to a safe height. Subsequently, the turntable 24 drives the support plate 25 and the adsorbed stone to rotate 90 degrees, completing the orientation adjustment of the stone and ensuring that the stone moves to the lower end of the fixed part 6 without interference.

[0058] After the suction and rotation are completed, the servo motor 32 drives the rotating shaft 30 to rotate via the belt 33; the rotating shaft 30 drives the transmission belt 31 to rotate via the synchronous pulley, and the transmission belt 31 drives the entire support plate 11, the drive unit 2 on it, the suctioned stone and the fixed transport vehicle 13 together via the connecting seat 34 to move smoothly along the length of the rectangular frame 100. The support plate 11 is accurately transported to the top of the target paving position and then stops.

[0059] The telescopic section of hydraulic cylinder 22 extends downward, driving the entire component holding the stone to descend. After the stone is lower than the fixed part 6, the rotary table 24 drives the stone to rotate 90 degrees in the opposite direction to reset it, so that it fits the ground in the correct posture. Then, the electric suction cup 2 150 releases the vacuum adsorption to complete the laying of a single stone. After that, the support plate 11 can continue to move and repeat the above process to work on the next stone.

[0060] like Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, the fixing part 6 includes a fixing seat 60. Multiple fixing seats 60 are evenly fixedly installed on the lower end of the horizontal section of the rectangular frame 100. A rectangular hole is opened on the fixing seat 60. A hydraulic cylinder 61 is fixedly installed in the rectangular hole. The telescopic section of the hydraulic cylinder 61 slides through the fixing seat 60 and is fixedly installed on a connecting plate 62. Two electric suction cups 63 are fixedly installed on the lower end of the connecting plate 62. Support columns 64 are slidably installed on both the left and right sides of the fixing seat 60. The lower end of the support column 64 is fixedly connected to the upper end of the connecting plate 62.

[0061] like Figure 1 and Figure 4 As shown, the pressing part 5 includes a hydraulic cylinder 50. The lower end of the support plate 11 is fixedly installed with the hydraulic cylinder 50 through a support frame. The telescopic section of the hydraulic cylinder 50 slides through the support frame and is fixedly installed with a bracket 51. The pressure roller 14 is rotatably installed on the bracket 51.

[0062] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, in specific operation, firstly, the telescopic section of the hydraulic cylinder 61, installed in the multiple fixed seats 60 at the lower end of the horizontal section of the rectangular frame 100, extends outward, pushing the connecting plate 62 fixed thereto to move downward; when the connecting plate 62 moves downward, the support columns 64 fixedly connected to its left and right sides slide smoothly within the fixed seats 60, providing stable guidance and support for the connecting plate 62 and preventing it from deflecting; when the connecting plate 62 descends to the set position, the electric suction cup 63 precisely and tightly adheres to and covers the two adjacent stones that have been laid, and then the electric suction cup 63 is activated, generating a strong suction force to lift the two adjacent stones. The materials are firmly adsorbed and fixed, thus forming a whole from two independent stones through the mechanical connection of the connecting plate 62 and the electric suction cup 63. At the same time, since the connecting plate 62 is slidably connected to the fixing seat 60 through the support column 64, and the fixing seat 60 is directly fixed on the rectangular frame 100, which is the main skeleton of the device, when the electric suction cup 63 adsorbs the stone, it achieves a rigid connection with the fixing frame 10, forming an integral structure. This state can effectively restrain any slight displacement or warping of the stone that may occur during subsequent moving operations, until the fixing part 6 releases the adsorption and the device moves to the next work position.
