[0022] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0023] Reference Figures 1-6 ,in Figure 6The conduit is not shown. According to an embodiment of this utility model, a novel gantry unloading machine includes two parallel ground rails 1. A moving vehicle 2 for transporting stones is mounted on the ground rails 1. Support frames 3 are mounted on both sides of the ground rails 1. A crossbeam 4 perpendicular to the ground rails 1 is positioned between the support frames 3. A transmission device is mounted on the side wall of the crossbeam 4, and a cutting device is mounted on the transmission device to drive the cutting device to move along the crossbeam 4 to cut the stones. A transmission device is mounted on the upper surface of the crossbeam 4, and a clamping device is mounted on the transmission device to clamp the cut stone slabs. A movable device is mounted on one side of the support frame 3 to change the state of the stone slabs clamped by the clamping device. A column 5 is set on one side of the unloading machine, and a transmission device is set on the column 5. The transmission device is equipped with an adsorption device that can flatten the stone slabs. The transmission devices on the upper surface and side wall of the crossbeam 4 and the transmission devices on the column 5 have the same structure and operating principle. The unloading machine drives the cutting device and the clamping device to move through the transmission devices on the upper end and side of the crossbeam 4. After the cutting device cuts the stone horizontally, the clamping device clamps it and moves it to the movable device to change from a vertical state to a horizontal state. Finally, the adsorption device flattens the cut stone slabs one by one on the ground for screening. The screened stone slabs can be picked up by the adsorption device and placed on the transport vehicle.

[0024] Furthermore, the transmission device includes two parallel guide rails 6, each with a slider 7. A movable block 8 is fixedly connected to the slider 7, a support block 9 is fixedly mounted on the movable block 8, and a fixed block 10 is mounted on the support block 9. A transmission motor 11 is mounted on the side of the fixed block 10. The output end of the transmission motor 11 is connected to a rotating shaft extending into the fixed block 10. A drive gear 12 is fixedly mounted on the rotating shaft. The drive gear 12 meshes with a driven gear 13. The driven gear 13 is located at one end of a drive shaft 14. The other end of the drive shaft 14 passes through the fixed block 10, the support block 9, and the movable block 8 and is connected to a drive gear 15. The drive gear 15 meshes with a rack 16 located between the guide rails 6. The transmission motor 11 drives the drive gear 12 to rotate, thereby causing the driven gear 13, the drive shaft 14, and the drive gear 15 to rotate. Since the drive gear 15 is connected to the rack 16, the movable block 8 can move on the crossbeam 4 or on the column 5.

[0025] Furthermore, the cutting device includes a drive motor 17 fixedly mounted on a movable block 8 on the side wall of the crossbeam 4. The output end of the drive motor 17 is connected to a rotating shaft, and a circular cutter 18 is fixedly mounted on the lower end of the rotating shaft. The drive motor 17 can drive the rotating shaft and the cutter 18 to rotate, thereby cutting the stone and cutting the stone slab off the stone.

[0026] Furthermore, the clamping device includes a first fixed frame 19 mounted on a movable block 8 on the upper surface of the crossbeam 4. A first cylinder 20 is mounted at the end of the first fixed frame 19. A support rod 21 is fixedly mounted at the lower end of the first cylinder 20. Brackets 22 are fixedly mounted at both ends of the support rod 21. A second cylinder 23 is mounted on the bracket 22. A main clamping plate 24 is fixedly mounted on the lower surface of the bracket 22. A connecting rod 25 is hinged to the front end of the second cylinder 23. The middle position of the connecting rod 25 is hinged to the front end of the bracket 22. The lower end of the connecting rod 25 is fixedly mounted with a connecting rod 24. The clamping plate 24 is used in conjunction with the auxiliary clamping plate 26; the end of the first fixing frame 19 is also provided with a first auxiliary rod 27, the lower end of the first auxiliary rod 27 is fixedly connected to the center of the support rod 21; the first cylinder 20 can drive the bracket 22 to rise and fall, so that the main clamping plate 24 and the auxiliary clamping plate 26 are located on both sides of the stone slab, and then the second cylinder 23 pushes the connecting rod 25, the middle position of the connecting rod 25 rotates around the front end of the bracket 22, and the auxiliary clamping plate 26 at the lower end of the connecting rod 25 is close to the main clamping plate 24, so that the main clamping plate 24 and the auxiliary clamping plate 26 can clamp the stone slab.

[0027] Furthermore, the movable device includes a placement frame 28, with movable plates 29 hinged to both ends of the placement frame 28 near the support frame 3. The front end of the movable plate 29 is provided with a protruding rod 30 for placing the stone slab, and the rear end of the movable plate 29 is hinged to one end of a third cylinder 31. The other end of the third cylinder 31 is fixedly located at the bottom of the rear end of the placement frame 28. When the cut stone slab is clamped and moved to the protruding rod 30 and rests against the movable plate 29, the movable plate 29 is then rotated to a horizontal position by the third cylinder 31.

[0028] Furthermore, the adsorption device includes a second fixed frame 32 mounted on a movable block 8 on the column 5. A fourth cylinder 33 is mounted at the end of the second fixed frame 32, and an adsorption frame 34 is fixedly connected to the lower end of the fourth cylinder 33. Multiple suction cups 35 are spaced apart on both sides of the adsorption frame 34, and the suction cups 35 are connected to a vacuum generator 36 mounted on the adsorption frame 34 via conduits. A second auxiliary rod 37 is also mounted at the end of the second fixed frame 32, and the lower end of the second auxiliary rod 37 is fixedly connected to the center of the adsorption frame 34. When the stone slab is in a horizontal state, the vacuum generator 36 causes the suction cups 35 of the adsorption frame 34 to generate suction, and the fourth cylinder 33 drives the adsorption frame 34 to rise and fall, so that the suction cups 35 hold the stone slab. Under the drive of the transmission device, the stone slabs are placed one by one on the floor, so that the quality and texture of the cut stone slabs can be viewed and classified. Finally, stone slabs with the same texture are picked up by the suction cups 35 and stacked together for transportation.

[0029] In practice, a stone block that has been vertically cut but whose lower end is not completely cut is placed on a moving vehicle 2 and moved to a designated position via a ground rail 1. A transmission device moves the clamping device to the top of the stone block. A first cylinder 20 drives a support 22 to rise and fall, positioning the main clamping plate 24 and the auxiliary clamping plate 26 on either side of the stone block. Then, a second cylinder 23 pushes a connecting rod 25, causing the middle position of the connecting rod 25 to rotate around the front end of the support 22. The auxiliary clamping plate 26 at the lower end of the connecting rod 25 then moves closer to the main clamping plate 24, thus clamping the stone block. The transmission device then moves the cutting device, causing the drive motor 17 to move. The drive motor 17 drives the rotating shaft and the cutter 18 to rotate. This allows for the cutting of stones, removing stone slabs from the stones. At this point, the cut stone slabs are still held in place and moved to the protruding rod 30 and resting against the movable plate 29 via the transmission device. Then, the movable plate 29 is rotated horizontally by the third cylinder 31. The vacuum generator 36 then causes the suction cups 35 of the suction frame 34 to generate suction, and the fourth cylinder 33 drives the suction frame 34 to rise and fall. This allows the suction cups 35 to hold the stone slabs, and under the drive of the transmission device, the stone slabs are placed one by one on the floor. This allows for the inspection of the quality and texture of the cut stone slabs and their classification. Finally, stone slabs with the same texture are picked up by the suction cups 35 and stacked together for transportation.
