Description

Technical Field

[0001] This utility model belongs to the field of stone processing technology, and in particular relates to a hoisting device for stone processing. Background Technology

[0002] Stone is a natural or man-made decorative material that is widely used in all aspects of life. Because of its heavy weight, it is not easy to move manually, so hoisting devices are often used to move stone during processing.

[0003] Chinese patent CN220317126U discloses a stone lifting device for stone processing, including a frame. Two connecting plates are hinged internally to the frame, and two hydraulic rods are also hinged internally. Each hydraulic rod has a movable seat hinged to its telescopic end. The upper surface of each movable seat contacts the bottom surface of the connecting plate. Two sets of connecting springs are fixedly installed on the upper surface of each connecting plate, and a support plate is fixedly installed at the top of each set of connecting springs. Two cylinders are fixedly installed on the inner top wall of the frame, and a movable plate is fixedly installed at the telescopic ends of the two cylinders. Two electric push rods are provided on the bottom surface of the movable plate, and a clamping plate is fixedly installed at the telescopic end of each electric push rod. This invention, by incorporating a frame, connecting plates, hydraulic rods, movable seats, connecting springs, and support plates, can solve the problem of stone easily falling off during lifting. However, the structure is relatively complex and may require more frequent maintenance and inspection. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a hoisting device for stone processing, which achieves the effect of simple structure and stable movement of stone.

[0005] In view of this, the present invention provides a hoisting device for stone processing, comprising: a base, wherein fastening devices are slidably disposed at both ends of the base; the fastening devices include a support plate that slides on the base, wherein a first plate is disposed on the support plate, and a second plate is movably disposed on the support plate corresponding to the first plate, wherein the second plate and the first plate can clamp the stone slab disposed between the first plate and the second plate when they are closed.

[0006] In this technical solution, the stone slab is placed on the support plates of the fastening devices on both sides. The second plate is movably set, and the second plate and the first plate are closed to clamp the stone slab placed on the support plate. The stability of the stone slab is ensured as the lifting base moves the stone slab. At the same time, the fastening device is slidably set on the base, and the position of the fastening device can be adjusted according to the size of the stone slab to ensure the stability of the stone slab hoisting.

[0007] In the above technical solution, a slider is further provided at the bottom of the support plate. The slider is slidably disposed in a corresponding groove provided in the base plate. A bidirectional screw is rotatably provided in the groove along the length direction. One end of the bidirectional screw passes through the base and is fixedly connected to a turntable. The slider is provided with a threaded hole corresponding to the screw.

[0008] In this technical solution, the slider is slidably set in the groove, and the slider abuts against the inner wall of the groove. The slider and the double-ended screw are threadedly connected. When the double-ended screw rotates, the fastening devices threaded at both ends of the double-ended screw move closer or further apart, which can adjust the fastening position for different specifications of stone slabs. At the same time, the two fastening devices slide symmetrically on the seat plate, which can ensure the stability of the center of gravity when hoisting the stone slab and prevent the slab from tilting or slipping due to the shift of the center of gravity, thus improving the safety and stability of hoisting.

[0009] In the above technical solution, a "T"-shaped limiting block is further provided at the bottom of the fastening device support plate, and the limiting block is slidably connected to the limiting groove provided in the corresponding limiting block of the seat plate.

[0010] In this technical solution, the limiting groove and the sliding groove extend in the same direction. The setting of the limiting block and the limiting groove can prevent the support plate from undergoing excessive deformation or displacement during the force process, thereby protecting the integrity and functionality of the fastening device.

[0011] In the above technical solution, the first plate is fixedly connected to the support plate and is provided with a first flange. The second plate is rotatably connected to the support plate and is provided with a second flange corresponding to the first flange. The first plate and the second plate are respectively provided on both sides of the support plate. When they are closed, the flanges provided on the corresponding sides of the first plate and the second plate are fixed by fasteners.

[0012] In this technical solution, before the stone slab is placed, the first and second flanges are far apart, and the fastening device is in an open state, which facilitates the placement of the stone slab. After placement, the second plate is rotated, and the first and second flanges come closer together until they touch, and are fixedly connected by fasteners such as bolts and screws.

[0013] In the above technical solution, the support plate and the second plate are further connected by a hinge.

[0014] In the above technical solution, a handle is further provided on the outer surface of the second plate near the flange.

[0015] In this technical solution, the handle is set horizontally, so that the operator can turn the handle to open the top of the second plate, which facilitates the insertion of the stone slab.

[0016] In the above technical solution, furthermore, rubber layers are fixedly connected to the inner sides of both the first and second plates.

[0017] In this technical solution, when the plates are tightly pressed together to compress the stone slab, the rubber layer will act as a buffer to prevent the plates from directly contacting the stone slab and causing scratches or damage, or even causing the stone slab's edges to crack under pressure.

[0018] In the above technical solution, a pad is further provided on the base, and the pad is disposed between the two fastening devices.

[0019] In this technical solution, the pad plate helps the fastening devices on both sides to share the pressure of the stone slab.

[0020] In the above technical solution, the pad extends to both sides with extension portions, and the extension portions are provided with hollowed-out mesh.

[0021] In this technical solution, the stone slab is bound by ropes passing through the grid on both sides of the extension section, which further increases the stability of the stone slab placed on the seat. In this embodiment, the ropes pass through a single grid on both sides of the extension section to bind the stone slab, but other embodiments are not limited to this rope fixing method.

[0022] Furthermore, in the above technical solution, lifting blocks are symmetrically arranged on the side wall of the base.

[0023] In this technical solution, there are four lifting blocks, symmetrically arranged on the side wall of the base. They are connected to the lifting device above by ropes. The lifting device can be a gantry crane or other lifting device, which ensures that the load is effectively distributed during lifting. The symmetrical layout ensures that the force is evenly distributed during lifting and prevents tilting or rotation caused by the shift of the center of gravity.

[0024] The beneficial effects of this utility model are:

[0025] 1. Place the stone slab on the support plate of the fastening device on both sides. The second plate is movable. Close the second plate and the first plate to clamp the stone slab placed on the support plate. Ensure the stability of the stone slab while the lifting base moves the stone slab.

[0026] 2. At the same time, the fastening device is slidably mounted on the base, and the position of the fastening device can be adjusted according to the size of the stone slab to ensure the stability of the stone slab hoisting;

[0027] 3. The stone slabs are secured by ropes passing through the mesh on both sides of the extension, further increasing the stability of the stone slabs placed on the seat. Attached Figure Description

[0038] Example 1:

[0039] like Figure 1-3 As shown, this embodiment provides a hoisting device for stone processing, including: a base 1, with fastening devices 2 slidably disposed at both ends of the base 1; the fastening devices 2 include support plates 3 slidably disposed on the base 1, a first plate 4 disposed on the support plate 3, and a second plate 5 movably disposed on the support plate 3 corresponding to the first plate 4. The second plate 5 and the first plate 4 can be clamped together to clamp a stone slab 6 disposed between the first plate 4 and the second plate 5. When the stone slab 6 is placed on the support plates 3 of the fastening devices 2 on both sides, the second plate 5 is movably disposed, clamping the second plate 5 and the first plate 4, thus clamping the stone slab 6 placed on the support plate 3. This ensures the stability of the stone slab 6 while the base 1 is lifted and the stone slab 6 is moved. At the same time, the fastening devices 2 are slidably disposed on the base 1, and the position of the fastening devices 2 can be adjusted according to the specifications of the stone slab 6 to ensure the stability of the hoisting of the stone slab 6.

[0040] In this embodiment, the stone being hoisted is a slab-shaped stone, hence it is called stone slab 6. This device can also be used as a hoisting device for other shapes such as stone pillars.

[0041] like Figure 1-2 As shown, a slider 7 is provided at the bottom of the support plate 3. The slider 7 is slidably disposed in a corresponding groove 8 provided in the base plate. A bidirectional screw 9 is rotatably disposed in the groove 8 along its length. One end of the bidirectional screw 9 passes through the base 1 and is fixedly connected to a turntable 23. The slider 7 is provided with a threaded hole 10 corresponding to the screw. The slider 7 is slidably disposed in the groove 8, and the slider 7 abuts against the inner wall of the groove 8. The slider 7 and the bidirectional screw 9 are threadedly connected. By rotating the turntable 23, the bidirectional screw 9 is driven to rotate. The fastening devices 2 threadedly connected to both ends of the bidirectional screw 9 move closer or further apart, which can adjust the fastening position for stone slabs 6 of different specifications. At the same time, the two fastening devices 2 slide symmetrically on the base plate, which can ensure the stability of the center of gravity when hoisting the stone slab 6, prevent the slab from tilting or slipping due to the shift of the center of gravity, and improve the safety and stability of hoisting.

[0042] like Figure 3 As shown, a "T"-shaped limiting block 11 is also provided at the bottom of the support plate 3 of the fastening device 2. The limiting block 11 is slidably connected to the limiting groove 12 provided in the corresponding limiting block 11 on the base plate. The limiting groove 12 and the sliding groove 8 extend in the same direction. The setting of the limiting block 11 and the limiting groove 12 can prevent the support plate 3 from undergoing excessive deformation or displacement during the force process, thereby protecting the integrity and functionality of the fastening device 2.

[0043] The first plate 4 is fixedly connected to the support plate 3 and has a first flange 13. The second plate 5 is rotatably connected to the support plate 3 and has a second flange 14 corresponding to the first flange 13. The first plate 4 and the second plate 5 are respectively located on both sides of the support plate 3. When closed, the flanges on the corresponding sides of the first plate 4 and the second plate 5 are fixed by fasteners 15. Before the stone slab 6 is placed, the first flange 13 and the second flange 14 are far apart, and the fastening device 2 is in an open state to facilitate the placement of the stone slab 6. After placement, the second plate 5 is rotated, and the first flange 13 and the second flange 14 move closer together until they abut against each other, and are fixedly connected by fasteners 15 such as bolts and screws.

[0044] The support plate 3 and the second plate 5 are connected by a hinge.

[0045] A handle 16 is provided on the outer surface of the second plate 5 near the flange. The handle 16 is horizontally positioned so that the operator can rotate the second plate 5 to open the top, making it easier to insert the stone slab 6.

[0046] Rubber layers 17 are fixedly connected to the inner sides of both the first plate 4 and the second plate 5. When the plates are tightly pressed together, the rubber layers 17 act as a buffer to prevent the plates from directly contacting the stone slab 6 and causing scratches or damage, or even causing the edges of the stone slab 6 to crack under pressure.

[0047] Four lifting blocks 22 are symmetrically arranged on the side wall of the base 1. They are connected to the lifting device above by ropes. The lifting device can be a gantry crane or other lifting device, which ensures that the load is effectively distributed during lifting. The symmetrical layout ensures that the force is evenly distributed during lifting and prevents tilting or rotation caused by the shift of the center of gravity.

[0050] like Figure 1 and Figure 2 As shown, a pad 18 is provided on the base 1, and the pad 18 is positioned between the two fastening devices 2. The pad 18 helps the fastening devices 2 on both sides to share the pressure of the stone slab 6.

[0051] The pad 18 extends to both sides with extension portions 19, and the extension portions 19 are provided with a hollowed-out mesh 20.

[0052] The stone slab 6 is bound by rope 21 through the mesh 20 on both sides of the extension 19, which further increases the stability of the stone slab 6 placed on the seat. In this embodiment, the rope 21 is bound to the stone slab 6 through a single mesh 20 on both sides of the extension 19, but other embodiments are not limited to this rope 21 fixing method.
