Description

Technical Field

[0001] This utility model relates to the field of stone lifting tools, specifically a stone lifting tool for stone processing. Background Technology

[0002] Stone, as a high-end building decoration material, is widely used in interior and exterior decoration design, curtain wall decoration, and public facility construction. Commonly available stone on the market is mainly divided into natural stone and artificial stone. Natural stone is further classified into slate and granite based on its physical and chemical properties. Artificial stone is divided into terrazzo and synthetic stone based on its manufacturing process. Terrazzo is made by pressing cement, concrete, and other raw materials; synthetic stone is made from crushed natural stone as raw material, plus adhesives, and then pressed and polished. Since the latter two are artificially made, their strength and value are not as high as natural stone. Stone is a high-end building decoration material. Natural stone is broadly classified into granite, slate, sandstone, limestone, and volcanic rock. With the continuous development and progress of science and technology, artificial stone products are constantly evolving, and their quality and aesthetics are no less than those of natural stone. With the development of architectural design, stone has long been one of the important raw materials for construction, decoration, roads, and bridges. Currently, processing equipment has a limited height, making it inconvenient to transport stone slabs. Traditional lifting devices are basically composed of simple lifting ropes and support plates, which cannot guarantee the stability of the stone clamping when moving up and down. Therefore, it is particularly important to improve existing stone lifting devices and design a new type of stone lifting device for stone processing to overcome the above-mentioned technical defects and improve the overall practicality of stone lifting devices.

[0003] Chinese Patent No. CN221140894U discloses a stone lifting tool for stone processing, comprising two sets of bases, each with a main rod mounted on its top. A support rod is installed inside the main rod, and a crossbeam is mounted on the top of the inner side of the support rod. A clamping mechanism is installed below the crossbeam. The clamping mechanism includes a rectangular box, an arc-shaped plate, a fixing frame, a sliding rod, a first connecting rod, a second connecting rod, a connecting block, a toothed plate, and a gear. The rectangular box is fixedly connected to the bottom of the crossbeam, the arc-shaped plate is fixedly connected to the inside of the rectangular box, the fixing frame is fixedly connected to the left and right sides of the bottom of the arc-shaped plate, the sliding rod is fixedly connected to the inside of the fixing frame, and the front and rear sides of the top of the first connecting rod are slidably connected to the outside of the sliding rod.

[0004] However, the above has the following shortcomings: 1. According to the description in the above patent, although the clamping device provides clamping force, the stone is suspended in the middle by clamping only on both sides, which makes the stone unevenly stressed. Therefore, a large clamping force is required to ensure the stability of the clamping and lifting process. When the clamping force is too large, the stone will break, making it impossible to process, wasting raw materials and reducing work efficiency.

[0005] 2. The above-mentioned patent relies on the clamping plate to provide pressure and clamp the side of the stone. It relies on the friction between the anti-slip pad on the side of the clamping plate and the stone to lift the stone. However, the friction is not controllable and the stone is prone to slipping. If workers or items pass under the clamping device, the stone may fall and cause personal injury or property damage. Utility Model Content

[0006] To overcome the shortcomings of the prior art, this utility model solves the technical problem by setting a fixed plate in the middle of the clamping plate and setting a ventilation support hole on the fixed plate. By using a fan to draw air, the ventilation support hole generates negative air pressure, giving the center of the stone an upward lifting force, making the stone more stable and preventing the stone from breaking due to excessive clamping force. The clamping plate is set with a support plate on its surface, which can both lift the stone by clamping and rotate the support plate to provide lateral support, thus improving the safety of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a stone lifting tool for stone processing, comprising a hanging frame and a fixing plate. Multiple support rods are symmetrically distributed and fixedly connected inside the hanging frame. A support block is fixedly connected to the lower end of each support rod. A fixing plate is movably connected to the lower end of each support block. An air pump is fixedly connected to the surface of the support block. Multiple air extraction support holes are mirror-distributed on the fixing plate. Each air extraction support hole has an air extraction vent at its top, and each air extraction vent is connected to the air pump. A clamping device is movably connected inside the hanging frame. The clamping devices are symmetrically distributed on both sides of the air extraction support holes, and the centerline of the clamping device is collinear with the centerline of the air extraction support hole.

[0008] Furthermore, the clamping device includes a clamping plate, a rotating shaft seat fixedly connected to the inner surface of the clamping plate, a rotating shaft rotatably connected inside the rotating shaft seat, support plates fixedly connected to both sides of the rotating shaft, a plurality of cylinder rotating shaft seats linearly distributed on the bottom surface of the inner surface of the clamping plate, a rotating shaft rotatably connected at the center of each cylinder rotating shaft seat, a cylinder connecting shaft seat fixedly connected to the surface of each rotating shaft located inside the cylinder rotating shaft seat, and a pump cylinder body fixedly connected to the square bottom surface of each cylinder connecting shaft seat. The lower surface of the support plate is linearly distributed and fixedly connected with cylinder rotating shaft seats, cylinder connecting shaft seats and rotating shafts corresponding to the bottom surface of the inner surface of the clamping plate, and the telescopic end of the pump is fixedly connected to the square bottom surface of each cylinder connecting shaft seat near the support plate.

[0009] Furthermore, the surface of the air pump is symmetrically provided with multiple air intake holes and air outlet holes. The air intake holes are connected to the multiple air intake holes by flexible hoses. Each clamping plate has a through hole on its surface. Each air pump cylinder is provided with an air pump inlet. Each air outlet hole is connected to the multiple air pump inlets by a flexible hose passing through the through hole.

[0010] Furthermore, a movable block is movably connected inside the hanger. The lower end of each movable block is fixedly connected to the cylinder of a hydraulic rod. Slide seats are symmetrically and fixedly connected to the surface of the cylinder of the hydraulic rod. A fixing block is fixedly connected to the telescopic end of the hydraulic rod. One side of the fixing block is fixedly connected to the outside of the clamping plate. Extension blocks are symmetrically and fixedly connected to the surface of the fixing block. A slide rod is fixedly connected to the upper end of each extension block. Each slide rod is slidably connected to the slide seat at the corresponding position.

[0011] Furthermore, the surface of the exhaust support hole is symmetrically provided with movable slots, each movable slot is rotatably connected to a lead screw, each lead screw is rotatably connected to a hanger, and the surface of the hanger is fixedly connected to a first motor at the corresponding position of each lead screw. The drive end of the first motor is driven to drive the lead screw, and the surface of each lead screw is driven to drive a movable block. Each first motor drives the lead screw to rotate at the same frequency, so that each movable block moves at the same speed.

[0012] Furthermore, the lower end of the hanger is symmetrically and linearly arranged with multiple self-locking casters, and the lower end of the exhaust support hole is fixedly connected with a sealing ring. The sealing ring can deform and fit against the stone surface to produce good sealing performance. The end of the support plate away from the rotation axis is an acute-angled bevel, which can scoop up the stone from below.

[0013] In summary, compared with the prior art, the beneficial effects of this utility model are as follows: (1) A fixed plate is set up, and an exhaust support hole is set on the fixed plate. The air in the exhaust support hole is extracted after contact with the stone through the exhaust support hole, so that negative pressure is generated in the exhaust support hole, which generates a lifting force on the stone. This avoids the situation where the stone is not supported at the center when it is lifted, so that a large clamping force is required to ensure the stability of the clamping and lifting process. When the clamping force is too large, the stone will break. In addition, the exhaust support hole generates more force on the stone in the same direction, so that the stone rises stably.

[0014] (2) A support plate is set up so that the stone is lifted up when it is clamped. The support plate is gradually raised by the cylinder so that the stone can get a larger support area, making the stone rise more stable. Under the clamping action of multiple exhaust support holes and the support plate, the stone itself has a more stable shape. Attached Figure Description

Detailed Implementation

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] like Figure 1 , Figure 3 , Figure 5 As shown, a stone lifting tool for stone processing includes a hanger 10 and two clamping plates 26 symmetrically distributed and movably disposed within the hanger 10. A rotating shaft seat 28 is fixedly connected to the inner surface of each clamping plate 26, and a rotating shaft 29 is rotatably connected to the center of each rotating shaft seat 28. Support plates 25 are fixedly connected to both sides of the rotating shaft 29. Three cylinder rotating shaft seats 30 are linearly distributed and fixedly connected to the bottom surface of each clamping plate 26. Each cylinder rotating shaft seat 30 has a rotating shaft 32 rotatably connected inside it, and each rotating shaft 32 is located within the rotating area of ​​the cylinder. A cylinder connecting shaft seat 31 is fixedly connected to the inner surface of the shaft seat 30. The cylinder body of the air pump 34 is fixedly connected to the square bottom surface of each cylinder connecting shaft seat 31. Three sets of cylinder rotating shaft seats 30, cylinder connecting shaft seats 31 and rotating shaft 32 corresponding to the surface of the clamping plate 26 are linearly distributed and fixedly connected to the lower surface of the support plate 25. The telescopic end of the air pump 34 is fixedly connected to the square bottom surface of the cylinder connecting shaft seat 31 in the cylinder rotating shaft seat 30 connected to the support plate 25. The end of the support plate 25 away from the rotating shaft 29 is an acute-angled bevel.

[0023] The support plate 25 with an acute-angled bevel allows it to lift the stone from the bottom, and the stone can slide along the surface of the support plate 25. By setting a rotating shaft 29 that is rotatably connected to the clamping plate 26, the cylinder rotating shaft seat 30 that is fixedly connected to the rotating shaft 29 can rotate along the axis of the rotating shaft 29. The air pump 34 drives the support plate 25 to rotate, so that the support plate 25 provides support force after clamping the stone.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, four support rods 36 are symmetrically distributed and fixedly connected inside the hanger 10. Support blocks 14 are fixedly connected to the lower ends of the four support rods 36. Two moving slots 37 are symmetrically opened on the surface of the support blocks 14. A lead screw 16 is rotatably connected in each moving slot 37. Each lead screw 16 is rotatably connected to the hanger 10. A first motor 12 is fixedly connected to the surface of the hanger 10 at the corresponding position of each lead screw 16. The transmission end of each first motor 12 is connected to the lead screw 16. A moving block 15 is connected to the surface of each lead screw 16. The lower end of each moving block 15 is fixedly connected to the cylinder of a hydraulic rod 17. A slide block 38 is symmetrically distributed and fixedly connected to the surface of the cylinder of each hydraulic rod 17. A fixing block 27 is fixedly connected to the telescopic end of each hydraulic rod 17. Each fixing block 27 is fixedly connected to the outer surface of the clamping plate 26 at the corresponding position. An extension block 40 is symmetrically distributed and fixedly connected to the surface of each fixing block 27. A slide rod 39 is fixedly connected to the upper end of each extension block 40. Each slide rod 39 is slidably connected to the slide block 38.

[0025] The first motor 12 drives the lead screw 16 to rotate, causing the moving block 15 to slide on the surface of the lead screw 16. This causes the two symmetrically distributed moving blocks 15 to move closer to each other, and causes the clamping plates 26 under the hydraulic rod 17 connected to the moving block 15 to move closer to each other, thus achieving the effect of clamping the stone.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the lower end of the support block 14 is fixedly connected to the cylinder body of the hydraulic cylinder 19, and the telescopic end of the hydraulic cylinder 19 is fixedly connected to the fixing plate 21. Four exhaust support holes 22 are symmetrically distributed and fixedly connected on the surface of the fixing plate 21. Each of the four exhaust support holes 22 has an exhaust hole 23 at its upper end. A sealing ring 24 is fixedly connected to the lower end of the four exhaust support holes 22. The sealing ring 24 can deform and tightly fit the stone surface to produce good sealing performance.

[0027] The exhaust support hole 22 is driven down by hydraulic cylinder 219, so that the sealing ring 24 on the exhaust support hole 22 is tightly attached to the stone surface, resulting in good sealing performance.

[0028] like Figure 1 , Figure 3 and Figure 6 As shown, a suction pump 13 is fixedly connected to the surface of the support block 14. Two sets of suction holes 20 and air outlet holes 35 are symmetrically distributed on the surface of the suction pump 13. The suction holes 20 are connected to the suction holes 23 through hoses. The clamping plate 26 has through holes 18 on its surface. Each air pump 34 has an air pump inlet 33 on its surface. Each air outlet hole 35 is connected to each air pump inlet 33 on the same side through a hose passing through the through hole 18.

[0029] The air pump 13 is used to extract air from the air support hole 22 after it is attached to the stone, so that the air support hole 22 exerts a lifting force on the stone, making the stone more stable during the lifting process. The air pump 13 is used to exhaust air through the air inlet 33 through the air outlet 35 and the through hole 18, so that the cylinder extends and the support plate 25 is lifted to support the stone, preventing the stone from falling due to insufficient friction, improving the safety of the device, and providing support to the bottom surface of the stone, making the stone lifting more stable.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the lower end of the hanger 10 has multiple sets of self-locking casters 11 arranged linearly in a symmetrical manner, and the self-locking casters 11 have a self-locking effect.

[0031] By setting self-locking casters 11, the hanger 10 can move in multiple directions, and the self-locking casters 11 can lock the device in a designated position, so that the device can transport the clamped stone to the designated position.

[0032] In this embodiment, initially, the operator connects the device to the power supply, the hydraulic rod 17, the hydraulic cylinder 19, and the air pump 34 are fully retracted, the end of the support plate 25 away from the rotating shaft 29 is attached to the edge of the bottom surface of the clamping plate 26, the two moving blocks 15 are located at the end of the corresponding lead screw 16 near the corresponding motor, the two air outlets 35 on the air pump 13 are connected to the three air pump inlets 33 on the corresponding side by passing through the through hole 18 on the corresponding side with hoses, the two suction holes 20 on the air pump 13 are connected to the suction holes 23 on the two suction support holes 22 on the corresponding side by hoses, and the sealing ring 24 at the lower end of each suction support hole 22 is in an extended state.

[0033] Before use, the operator moves the entire device to the stone placement position using the self-locking casters 11, adjusts the device position so that the stone position is controlled between the two clamping devices, locks the self-locking casters 11, and activates the hydraulic rods 17 on both sides, causing the hydraulic rods 17 to push the fixing block 27 down, causing the clamping device connected to the fixing block 27 to move down. Since the slide block 38 restricts the sliding direction of the slide rod 39, the fixing block 27 moves down parallel to the sliding direction of the extension block 40 without deflection.

[0034] When the hydraulic rod 17 pushes the clamping device down until the support plate 25 in the clamping device contacts the placement plane where the bottom of the stone is located, the operator starts the two first motors 12 at the same frequency to drive the corresponding lead screws 16 to rotate at the same speed, so that the two moving blocks 15 connected to the two lead screws 16 approach each other at the same speed, so that the two hydraulic rods 17 connected to the lower end of the two moving blocks 15 and the two clamping devices connected to the lower end of the two hydraulic rods 17 approach each other until the end of the support plate 25 away from the rotating shaft 29 contacts the bottom of the stone.

[0035] When the support plate 25 contacts the bottom surface of the stone, the hydraulic cylinder 219 pushes the fixing plate 21 downward, so that each exhaust support hole 22 on the fixing plate 21 contacts the stone surface. When the sealing ring 24 at the lower end of each exhaust support hole 22 is in contact with the stone surface, as the hydraulic cylinder 219 continues to press down, each sealing ring 24 deforms and tightly fits the stone surface, so that good airtightness is generated between the inside of each exhaust support hole 22 and the stone surface.

[0036] Subsequently, the operator turns on the air pump 13, which draws out the air between each air support hole 22 and the stone surface through each air vent 23 connected by the air vent 20 hose. This creates a negative pressure between each air support hole 22 and the stone surface, giving the stone an upward lifting force. Then, the hydraulic cylinder 19 contracts, causing the fixing plate 21 to rise and lifting the stone.

[0037] Meanwhile, the first motor 12 continues to drive the lead screw 16 to rotate, causing the two moving blocks 15 to continue to move closer to each other. Since the end of the support plate 25 away from the rotating shaft 29 is an acute-angled slope, as the moving blocks 15 continue to move closer, the bottom surface of the stone slides along the slope at the end of the support plate 25. At the same time, the air pump 13 supplies air to each air pump inlet 33 connected to the air outlet 35 through the through hole 18, causing the air pump 34 to extend. Driven by the air pump 34, the support plate 25 rotates upward along the axis of the rotating shaft 29 connected to the support plate 25, under the restriction of the rotating shaft seat 28, so that the bottom surface of the stone continues to slide along the surface of the support plate 25. When the two sides of the stone abut against the inner side surface of the clamping plate 26, the surface of the support plate 25 is completely perpendicular to the side surface of the clamping plate 26, so that the support plate 25 provides support force on both sides of the stone.

[0038] When the support plate 25 is perpendicular to the side of the clamping plate 26, the hydraulic rod 17 retracts at the same rate as the hydraulic cylinder 19, causing the hydraulic rod 17 to rise and the fixed block 27 to move upward, so that the fixed block 27 carries the clamping device upward, and the stone moves upward smoothly as a whole.

[0039] Once the stone is lifted to the designated position, the operator unlocks the self-locking casters 11 and moves the device, allowing the operator to move the stone to the processing position. After moving to the processing position, the operator reverses the air pump 13, causing it to extract gas from the cylinder of the air pump 34, causing the air pump 34 to contract. The support plate 25 moves downward in a circular motion along the axis of the rotating shaft 29, and the hydraulic cylinder 2 19 extends with the downward movement rate of the stone, ensuring that the stone still receives the lifting force provided by the ventilation support hole 22 while moving downward, maintaining the stability of the stone. At this time, the first motor 12 drives the lead screw 16 to reverse, causing the two moving blocks 15 to move away from each other, allowing the stone to slide down the support plate 25. After the stone is placed in the processing position, the air pump 13 blows air through the ventilation hole 23 into the ventilation support hole 22, eliminating the negative pressure between the ventilation support hole 22 and the stone contact surface, thus eliminating the lifting force of the ventilation support hole 22 on the stone. The stone is then removed from the device, completing the lifting and placement process.

[0040] After the work is completed, the operator moves the device out of the processing position, and the device returns to its initial position.

[0041] The self-locking caster 11, the air pump 13, the sealing ring 24 and the air pump 34 mentioned above are all mature existing technologies. The structure of the air pump 13 in the figure is only for illustration and does not represent the actual structure. It will not be described in detail in this article.
