Description

Technical Field

[0001] This utility model relates to the field of material hoisting technology, specifically a square plate hoisting and flipping structure. Background Technology

[0002] In the production, processing and installation of square or rectangular plates such as glass, stone and metal sheets, hoisting, flipping and posture adjustment operations are often required.

[0003] However, existing square plate hoisting structures mostly use fixed clamps. Because the clamp spacing is fixed, it is difficult to meet the hoisting needs of square plates of different lengths and specifications. When faced with square plates that exceed the preset size, special hoisting equipment must be replaced. Frequent equipment replacement seriously affects production efficiency. Secondly, when it is necessary to process the square plate on multiple sides, operators can only manually handle it or use other auxiliary tools to flip the square plate. This process is not only time-consuming and labor-intensive, but also poses safety risks.

[0004] Therefore, it is necessary to design a square plate hoisting and flipping structure that is highly adaptable and flexible in flipping. Utility Model Content

[0005] The purpose of this utility model is to provide a square plate hoisting and flipping structure to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a square plate hoisting and flipping structure, including a hanger, with the hangers on both sides arranged in parallel and an adjusting component for adjusting the distance between the hangers on both sides provided at the top of the hangers on both sides. The hanger includes a column, with the columns on both sides arranged in parallel and a top plate connected between the columns on both sides. The adjusting component includes a left-hand lead screw, a right-hand lead screw, and a crossbeam plate. Both ends of the left-hand and right-hand lead screws are provided with lead screw seats, which are detachably connected to the crossbeam plate. The crossbeam plate is provided with linear guide rails on both sides of the left-hand and right-hand lead screws. Connecting blocks are provided on both sides of the bottom surface of the top plate. A slider is connected to the bottom, which can slide along the linear guide rail. A movable seat is provided on both the left-hand lead screw and the right-hand lead screw, and the movable seat is connected to the top plate. A lead screw connector is connected between the left-hand lead screw and the right-hand lead screw. A first handwheel is provided at the end of the right-hand lead screw away from the left-hand lead screw. By shaking the first handwheel, the right-hand lead screw and the left-hand lead screw are driven to rotate, so that the movable seats on both sides move closer or further apart along the linear guide rail, thereby driving the hangers on both sides to move inward or outward at the same time to adjust the spacing to adapt to square plates of different lengths. A clamping assembly is installed at the bottom of the hangers on both sides, and a flipping assembly is provided on the clamping assembly.

[0007] According to the above technical solution, the clamping assembly includes mechanical grippers, a worm gear, and a drive motor. Worm wheels are meshed on both sides of the worm gear, and a transmission shaft is provided on the worm wheel. The transmission shaft is connected to the mechanical grippers. The end of the worm gear away from the worm wheel is connected to the output end of the drive motor. The drive motor drives the worm gear to rotate, and the worm gear drives the worm wheels on both sides to rotate relative to each other. The worm wheels drive the mechanical grippers on both sides to open and close relative to each other to clamp the square plate through the transmission shaft.

[0008] According to the above technical solution, a rotating cylinder is sleeved on the outside of the worm gear, and a gripper seat is connected to the end of the rotating cylinder away from the drive motor. The mechanical grippers on both sides and the worm wheels on both sides are all mounted on the gripper seat.

[0009] According to the above technical solution, the flipping assembly includes a ratchet, a pawl, and a fixing block. A ratchet seat and a cam seat are mounted on the fixing block. The flipping cylinder passes through the ratchet seat, and the drive motor is mounted on the ratchet seat. The ratchet is sleeved on the flipping cylinder. A cam is connected to one side of the cam seat, and a pawl seat is rotatably connected to the other side of the cam seat. The pawl is rotatably connected to the top of the pawl seat, and one end of the pawl is engaged with the ratchet opening of the ratchet. A first bearing is connected to one end of the pawl seat near the cam. The first bearing abuts against the cam. A second handwheel is connected to one side of the cam. By rotating the second handwheel, the cam is rotated. The eccentric profile of the cam pushes the first bearing, causing the pawl to push the ratchet to rotate. The ratchet drives the clamping assembly connected to the flipping cylinder, thereby adjusting the angle of the square plate.

[0010] According to the above technical solution, the hanger is provided with an installation plate, the installation plate is provided with a bearing seat, the bearing seat is provided with a second bearing, and the second bearing is sleeved on the tilting cylinder.

[0011] According to the above technical solution, the bottom of the hanger is connected to a base plate, a fixing plate is provided on the base plate, the flipping component is installed on the fixing plate, and the fixing plate has a straight groove below the cam to facilitate the rotation of the cam.

[0012] According to the above technical solution, the top plate is connected to the two sides with reinforcing ribs, and the two sides of the reinforcing ribs are connected to the hanging column.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] (1) By setting up a distance adjustment component, the left-hand screw, the right-hand screw and the screw connector are used to drive the two moving seats to move relative to each other along the screw line by shaking the first handwheel, thereby driving the hanger to adjust the distance synchronously, so as to achieve precise adaptation to square plates of different lengths. Compared with the traditional fixed specification hoisting structure, it can be compatible with square plates of various sizes without changing the equipment, significantly reducing the time spent on equipment replacement, and effectively improving production efficiency and equipment versatility.

[0015] (2) By setting up a flipping component, rotating the second handwheel causes the cam to rotate, and the cam's eccentric profile drives the pawl to drive the ratchet to rotate, thereby driving the clamping component connected to the flipping cylinder to achieve 360-degree free flipping of the square plate, replacing the traditional manual handling and adjustment of the square plate angle. This not only greatly reduces the labor intensity of operators and eliminates the safety hazards of manual operation, but also meets the needs of multi-faceted processing and significantly improves the processing efficiency of the square plate. At the same time, the pawl is locked at the ratchet opening of the ratchet. When the square plate is adjusted to the target angle, the pawl can effectively restrict the ratchet to rotate in the opposite direction, ensuring that the square plate remains stable and fixed during the processing.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the present invention, the solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] This utility model provides a technical solution: a square plate hoisting and flipping structure, including a hanger 10, with two hangers 10 arranged in parallel on both sides and an adjusting component 20 for adjusting the distance between the two hangers 10 on the top of each hanger 10. Each hanger 10 includes a hanging column 11, with two hanging columns 11 arranged in parallel on both sides and a top plate 111 connecting the two hanging columns 11. The adjusting component 20 includes a left-hand lead screw 21, a right-hand lead screw 22, and a crossbeam plate 23. Both ends of the left-hand lead screw 21 and the right-hand lead screw 22 are provided with lead screw seats 24, which are detachably connected to the crossbeam plate 23. The crossbeam plate 23 is provided with linear guide rails 231 on both sides of the left-hand lead screw 21 and the right-hand lead screw 22. Connecting blocks 112 are provided on both sides of the bottom surface of the top plate 111. The top plate 111 is connected to a slider 113, which can slide along the linear guide rail 231. A movable seat 25 is provided on both the left-hand screw 21 and the right-hand screw 22. The movable seat 25 is connected to the top plate 111. A screw connector 26 is connected between the left-hand screw 21 and the right-hand screw 22. A first handwheel 27 is provided at the end of the right-hand screw 22 away from the left-hand screw 21. By shaking the first handwheel 27, the right-hand screw 22 and the left-hand screw 21 are driven to rotate, so that the movable seats 25 on both sides move closer or further away from each other along the linear guide rail 231, thereby driving the two side hangers 10 to move inward or outward at the same time to adjust the spacing to adapt to square plates of different lengths. A clamping assembly 30 is installed at the bottom of the two side hangers 10, and a flipping assembly 40 is provided on the clamping assembly 30.

[0025] With this technical solution, the operator only needs to turn the first handwheel 27 with one hand to realize the synchronous inward or outward displacement of the two hangers 10 by utilizing the reverse transmission characteristics of the left-hand lead screw 21 and the right-hand lead screw 22. At the same time, the linear guide rails 231 set on both sides of the crossbeam plate 23 and the slider 113 below the bottom connecting block 112 of the top plate 111 form a precision guiding structure. This structure can not only reduce the frictional resistance when the hanger 10 moves, but also effectively distribute the radial load on the lead screw, greatly reduce the force distribution of the left-hand lead screw 21 and the right-hand lead screw 22, and avoid the lead screw from deforming or wearing due to long-term excessive radial force, thus significantly improving the stability and service life of the structure.

[0026] Furthermore, the clamping assembly 30 includes mechanical grippers 31, a worm gear 32, and a drive motor 33. Worm gears 321 are meshed on both sides of the worm gear 321, and a transmission shaft 322 is provided on the worm gears 321. The transmission shaft 322 is connected to the mechanical grippers 31. The end of the worm gear 32 away from the worm gears 321 is connected to the output end of the drive motor 33. The drive motor 33 drives the worm gear 32 to rotate, and the worm gear 32 drives the worm gears 321 on both sides to rotate relative to each other. The worm gears 321 drive the mechanical grippers 31 on both sides to open and close relative to each other to clamp the square plate through the transmission shaft 322.

[0027] With this technical solution, when the drive motor 33 drives the worm gear 32 to rotate, the worm wheels 321 on both sides rotate synchronously in opposite directions under the action of the worm gear 32. Then, through the transmission shaft 322, the mechanical gripper 31 completes a precise relative opening and closing action. When the mechanical gripper 31 contacts the surface of the square plate and reaches the set clamping force, the worm wheel 321 and worm gear 32 mechanism will automatically enter a self-locking state. It can maintain a stable clamping force without the need for an additional locking device, effectively preventing accidental release due to external disturbance or power failure of the drive motor 33, which would cause the square plate to slip.

[0028] Furthermore, a rotating cylinder 323 is sleeved on the outside of the worm 32. The end of the rotating cylinder 323 away from the drive motor 33 is connected to a gripper seat 311. The mechanical grippers 31 on both sides and the worm wheels 321 on both sides are all mounted on the gripper seat 311.

[0029] Through this technical solution, the integrated design of the tilting cylinder 323 and the gripper seat 311, which are sleeved on the outside of the worm gear 32, not only provides a stable support structure for the worm gear 321 and the mechanical gripper 31, but also realizes the overall tilting function of the clamping assembly 30. When the tilting assembly 40 drives the tilting cylinder 323 to rotate around the axis of the worm gear 32, the gripper seat 311 simultaneously drives the mechanical grippers 31 on both sides and the square plate held to achieve a 360-degree arbitrary angle tilting, effectively solving the limitations of traditional hoisting equipment in spatial posture adjustment.

[0030] Furthermore, the flipping assembly 40 includes a ratchet 41, a pawl 42, and a fixing block 43. A ratchet seat 431 and a cam seat 432 are mounted on the fixing block 43. The flipping cylinder 323 passes through the ratchet seat 431, and the drive motor 33 is mounted on the ratchet seat 431. The ratchet 41 is sleeved on the flipping cylinder 323. A cam 44 is connected to one side of the cam seat 432, and a pawl seat 421 is rotatably connected to the other side of the cam seat 432. The pawl 42 is rotatably connected to the top of the pawl seat 421. One end of the pawl 42 is engaged at the ratchet opening of the ratchet wheel 41. The pawl seat 421 is connected to a first bearing 422 at the end near the cam 44. The first bearing 422 abuts against the cam 44. A second handwheel 441 is connected to one side of the cam 44. By rotating the second handwheel 441, the cam 44 is rotated. The eccentric profile of the cam 44 pushes the first bearing 422, causing the pawl 42 to push the ratchet wheel 41 to rotate. The ratchet wheel 41 drives the clamping assembly 30 connected to the flipping cylinder 323, thereby adjusting the angle of the square plate.

[0031] With this technical solution, when the operator rotates the second handwheel 441 to drive the cam 44 to rotate, the eccentric profile of the cam 44 pushes the pawl seat 421 to swing around the fulcrum through the first bearing 422, so that the pawl 42 can achieve step-by-step pushing between the ratchet 41. By utilizing the unidirectional intermittent motion characteristics of the pawl 42 and the ratchet 41, the angle of the square plate can be finely adjusted. Each time the second handwheel 441 is rotated, the flip angle of the square plate corresponds to one tooth pitch of the ratchet 41. When the second handwheel 441 is stopped, the pawl 42 will immediately engage with the ratchet 41 to prevent the angle from shifting due to external force or vibration.

[0032] Furthermore, the hanger 10 is provided with a mounting plate 12, a bearing seat 121 is mounted on the mounting plate 12, a second bearing 122 is provided inside the bearing seat 121, and the second bearing 122 is sleeved on the tilting cylinder 323;

[0033] Through this technical solution, the second bearing 122 significantly reduces the rotational friction resistance of the tilting cylinder 323. At the same time, the second bearing 122 provides precise positioning and axial constraint for the tilting cylinder 323, ensuring that the tilting cylinder 323 does not move axially during high-speed rotation.

[0034] Furthermore, the bottom of the hanger 10 is connected to a base plate 13, and a fixing plate 131 is provided on the base plate 13. The flipping component 40 is installed on the fixing plate 131, and the fixing plate 131 has a straight groove 132 below the cam 44 to facilitate the rotation of the cam 44.

[0035] Through this technical solution, the base plate 13 and the fixing plate 131 at the bottom of the hanger 10 form a stable basic support structure, providing a reliable installation platform for the flipping assembly 40. The straight slot 132 provides sufficient space for the rotation of the cam 44, so that when the operator turns the second handwheel 441, the cam 44 can complete the rotation of the eccentric profile without obstruction.

[0036] Furthermore, the top plate 111 is connected to the two sides of the reinforcing ribs 114, and the two sides of the reinforcing ribs 114 are connected to the hanging column 11;

[0037] Through this technical solution, the reinforcing ribs 114 on both sides of the top plate 111 and the hanging column 11 form a triangular support structure, which significantly improves the overall rigidity of the hanger 10.

[0038] Working principle: When using this square plate hoisting and flipping structure, first adjust the spacing of the hangers 10 according to the length of the square plate. The operator drives the right-hand screw 22 and the left-hand screw 21 to rotate by turning the first handwheel 27. At this time, the movable seat 25 installed on the screw is driven by the screw thread and moves linearly along the screw. At the same time, the slider 113 on the bottom surface of the top plate 111 slides on the linear guide rail 231 to ensure that the two hangers 10 move inward or outward synchronously until the spacing is suitable for the size of the square plate.

[0039] After the spacing adjustment is completed, the drive motor 33 is started. The output end of the motor drives the worm 32 to rotate. The worm wheels 321 on both sides of the worm 32 rotate relative to each other under meshing transmission. The mechanical grippers 31 are driven to open and close relative to each other through the transmission shaft 322. When the mechanical grippers 31 contact the square plate and reach the preset clamping force, the worm wheels 321 and the worm 32 automatically lock to ensure that the square plate is firmly clamped.

[0040] If the square plate needs to be flipped, the operator turns the second handwheel 441, which drives the cam 44 to rotate. The eccentric profile of the cam 44 pushes the first bearing 422, causing the pawl seat 421 to swing around the fulcrum, which in turn drives the pawl 42 to push the ratchet 41 to rotate. Since the ratchet 41 is sleeved on the flipping cylinder 323, which is connected to the gripper seat 311, the rotation of the ratchet 41 drives the clamping assembly 30 and the square plate to flip synchronously. Each time the second handwheel 441 is turned, the flipping angle of the square plate corresponds to one tooth pitch of the ratchet 41, achieving precise angle adjustment. After the rotation stops, the pawl 42 engages with the ratchet mouth of the ratchet 41 to lock the angle.
