DETAILED DESCRIPTION

[0035] See also Figure 1-10 , the present invention provides a technical solution:.

[0036] Working principle:

[0037] Before construction, inspect and accept the stone materials and measure and lay out the stones. Adjust the position of the lifting frame 1 according to the laid out position. Before installing the stone materials, fill the square wooden frame with dry mortar.

[0038] The present invention transfers the stones to the storage table 3, transports and adjusts the stones through the storage table 3, and raises the storage table 3 to a position flush with the mounting table 2, so that the stones can be smoothly transferred from the storage table 3 to the mounting table 2, and then the stones are laid through the mounting table 2. Since the height of the storage table 3 is adjustable, it can adapt to the height of the stacked stones, reduce the loading height and distance, and install and lay through the mounting table 2, which reduces the risks in the process of lifting and installing heavy stones and is safer. Moreover, multiple stones can be placed on the storage table 3, and continuous laying can be achieved by loading once. The whole process has a high degree of automation, which greatly reduces the manpower input, and the laying is accurate and fast.

[0039] When the lifting frame 1 is placed, the cargo board 6 is located outside the stone material to be laid, and the height of the lifting frame 1 is adjusted at the same time, so that the laying position of the stone material is adjusted, thereby facilitating the subsequent automatic and accurate laying of the stone material.

[0040] The laying direction of the stone can be adjusted by the reversing table 10 to meet the requirements of horizontal or vertical laying. If no adjustment is required, there is no need to change the direction. After adjustment, the pushing screw 11 drives the pushing plate 12 to move in the direction of the cargo board 6, and then pushes the stones with adjusted directions to be transported on the installation table 2 until they are close to the cargo board 6. At this time, the stones to be laid are flush with the wall to be laid or the preset position. At the same time, when the pushing plate 12 reaches the position of the movable guide plate 9 during its movement, the two sides of the pushing plate 12 exceed the inner side of the movable guide plate 9. position, so the movable guide plate 9 can be pushed forward together, and due to the setting of the compensation plate 13, the board surface of the compensation plate 13 is flush with the inner board surface of the movable guide plate 9, so as to form a flat board surface and stick to the other side of the stone, and then form a specific guide slideway adapted to the stone with the cargo board 6. Since the movable guide plate 9 follows the push and move of the pushing plate 12, it can adapt to stones of different widths or stones of different directions, and can form guide slideways of different widths, so that the stone can be laid straight without being skewed.

[0041] When the pushing plate 12 and the spreading plate 6 are in contact with both sides of the stone, the spreading screw 14 drives the rear end push rod 15 to push the stone to one side so that it slides obliquely along the spreading roller 8. In this process, the front end of the stone is pushed and the falling process will be blocked by the slow-down block 17, thereby slowing down the falling speed of the stone. In the process of the slow-down block 17 gradually moving downward, on the guide frame of the involute slide 16, the slow-down block 17 gradually moves to both sides, so that after a corner of the stone is grounded, the slow-down block 17 is completely retracted into the inclined guide plate 7, and the stone can slide out smoothly.

[0042] Furthermore, when the cargo-laying screw 14 drives the rear push rod 15 to move, the inner rod 31 and the outer rod 30 can slide against each other, and then shorten with the movement of the rear push rod 15 until the front end of the stone is pushed to block the photoelectric sensor 34, so that the electromagnet of the inner rod 31 is connected and magnetically fixed to the outer rod 30, and the two cannot be shortened. At this time, the rear push rod 15 continues to move, and the front end of the stone is blocked by the slow-down block 17, so that it cannot fall freely. The slow-down block 17 needs to move with the rotation of the cargo-laying screw 14, so as to provide a stable and uniform descending speed, so that the stone slides down smoothly and lands on the ground; in the process of the slow-down block 17 gradually moving downward, on the guide frame of the involute slide 16, the slow-down block 17 gradually moves to both sides, and the slide column 33 gradually extends out of the ring 32, so that after a corner of the stone lands, the slow-down block 17 is completely retracted into the inclined guide plate 7, and the stone can slide out smoothly;

[0043] When the stone completely slides down, the photoelectric sensor 34 loses its shielding, the magnetic attraction between the inner rod 31 and the outer rod 30 disappears, the cargo spreading screw 14 retracts the rear end push rod 15, and the inner rod 31 and the outer rod 30 are gradually stretched until they are stretched to the limit, and the rear end push rod 15 continues to move backward to bring back the slow-down block 17 to reset it; and the other slow-down block 17 can be provided with a spring in the involute slide 16, and it can bounce back to its original position after the stone completely slides down.

[0044] Both sides of the cargo boards 6 are provided with inclined guide plates 7, so that the stones can be laid in two directions. When the lifting frame 1 moves until a layer of stones is laid, it can move backwards to continue laying without returning to the beginning to lay again, which saves time and improves efficiency. When changing the direction, it is necessary to adjust the initial position of the rear end push rod 15 to the other side, and at the same time remove the lower ring 32 and put it on the sliding column 33 of the slow-down block 17 on the other side.

[0045] When the stone tilts and slides to the ground in a corner, the lifting frame 1 is moved to the position of a stone. The stone automatically becomes flat during the movement. After the stone becomes flat, the position of the next stone is determined. The stone in the next position can be laid. The spacing between the stones is uniform and easier to control. The stone is laid flat and not skewed, and there is no need for repeated manual adjustment and alignment.

[0046] When the stock table 3 is loaded with materials and docked with the mounting table 2, the reversing turntable 10 rises and just enters the space between the pushing screws 11, and is nested under the pushing plate 12; the stock table 3 is flush with the top of the mounting table 2, and the pushing plate 12 runs smoothly; the outer arc cover plate 20 and the circular arc cover plate 19 close the space around the reversing turntable 10 to prevent stone leakage or bumping and poor operation; the loading roller 21, conveying roller 22, guide roller 23 and ball 24 can all assist in the movement of the stone, making it easy to be pushed.

[0047] In order to ensure the safety of stone transportation and laying, a peripheral edge 26 is provided to avoid risks such as slipping. When the push plate 12 moves, it passes through the peripheral edge 26 of the mounting table 2 through the peripheral edge slide groove 7, and the recessed window 28 of the same specification passes through the peripheral edge 26 of the inventory table 3, so that the push plate 12 can move smoothly while ensuring safety; when the push plate 12 reaches the movable guide plate 9 to push it to move, the two can cooperate through magnetic attraction, and then when the push plate 12 is reset, the movable guide plate 9 is driven to reset together. After reaching the extension block 29, the movable guide plate 9 cannot continue to move and can automatically disengage from the magnetic attraction; or the movable guide plate 9 is automatically pulled back by the action of the contraction spring when the push plate 12 is reset, so as to carry out the next guided laying.

[0048] The parallel wheels 37 can be attached to the curb of the site to be paved or the side of the foundation platform, so that the hoisting frame 1 can move in a straight line during the movement.

[0049] The inventory motor 41 can drive one of the inventory screws 39 to rotate through gear transmission, and then drive all the inventory screws 39 to rotate through chain transmission, thereby lifting or moving down the inventory platform 3, which is more reliable and stable; the installation motor 42 can drive one of the installation screws 40 to rotate through gear transmission, and then drive all the installation screws 40 to rotate through chain transmission, thereby driving the installation platform 2 to move up and down, thereby realizing the adjustment of the stone laying height, and can adapt to various heights, and can also be stably docked at the required height.

[0050] When loading materials onto the storage platform 3 , the stone can be clamped by the lifting clamp 45 and lifted by the winch 44 and then moved onto the storage platform 3 . The movable rod 43 allows the lifting clamp 45 to have a larger movable space, thereby adapting to the position where the materials are stacked and facilitating the transportation of the stone.

[0051] After the stones are laid, the joints on the outside need to be grouted and then watered for maintenance.
