Description

Technical Field

[0001] This invention relates to the technical field of prefabricated component hoisting, and in particular to a prefabricated component hoisting device with an adjustable function. Background Technology

[0002] Prefabricated buildings are constructed by prefabricating building components and accessories in a factory, then transporting them to the construction site, where they are assembled and installed using reliable connection methods. When constructing high-rise buildings, hoisting is generally used for installation.

[0003] Chinese patent document CN112340599B discloses a hoisting device for freely adjustable prefabricated building wall panels, including a main support rod, a diamond-shaped frame, and a cylinder. A connecting rod is connected to the top of the main support rod, and diamond-shaped frames are connected to the first and second telescopic supports. A connecting mechanism is sleeved on the outside of the main support rod, and a limit mechanism is connected to the front end of the first and second telescopic supports. A connecting gear is provided inside the connecting box, and the connecting gear meshes with a driven gear. A control mechanism is also provided inside the connecting box, and a wired control mechanism is connected to the bottom of the connecting box. This device, through the clamping mechanism and the wired control mechanism, can clamp the wall panel while also supporting the bottom of the wall panel, preventing swaying during hoisting and avoiding safety hazards to surrounding personnel.

[0004] The device in this design uses only positive and negative lead screws and clamping blocks to clamp and limit the wall panel, which has limited clamping force. In windy weather, the wall panel is prone to falling off. In addition, it cannot change the rotation speed of the wall panel when adjusting the angle, making it difficult to place the wall panel in the designated position at the predetermined angle.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] Example 1

[0037] like Figure 1-8As shown, this embodiment discloses a prefabricated component hoisting device with adjustable function, including a hollow load-bearing beam plate 1. The inner cavity of the hollow load-bearing beam plate 1 is provided with two L-shaped clamping plates 4 extending to the outer side of the hollow load-bearing beam plate 1. The bottom of the vertical portions of the two L-shaped clamping plates 4, which are close to each other, is provided with a powerful suction cup 5. By adding the powerful suction cup 5, the device can also adhere to the prefabricated component when clamping it, thereby increasing the structural stability between the device and the prefabricated component and reducing the probability of the prefabricated component falling. The outer surface of the side of the powerful suction cup 5 away from the L-shaped clamping plate 4 is provided with a sealing ring 51 to prevent air leakage. By setting the sealing ring 51, air inside the powerful suction cup 5 can only flow into the L-shaped clamping plate 4, pushing the clamping mechanism 6 outward, thereby further increasing the clamping force of the L-shaped clamping plate 4 on the prefabricated component. The bottom of the vertical part is provided with a flow groove 41 and a connecting groove 43. The flow groove 41 is annular and the flow groove 41 and the connecting groove 43 are at the same horizontal level. The left and right inner walls of the flow groove 41 are provided with multiple air inlet grooves 42 that connect the powerful suction cup 5 and the connecting groove 43 respectively, so that the air inside the powerful suction cup 5 can pass through the air inlet groove 42 and the flow groove 41 into the connecting groove 43 when the powerful suction cup 5 is compressed. The vertical part of the L-shaped clamping plate 4 is provided with an installation groove 1 at one end inside the powerful suction cup 5. The installation groove 1 is provided with a clamping mechanism 6 for increasing the clamping force. The clamping mechanism 6 is slidably connected in the installation groove 1 so that the air flowing into the connecting groove 43 can push the clamping mechanism 6 outward to squeeze the assembled component. The clamping mechanism 6 and the center line of the powerful suction cup 5 are on the same horizontal line.

[0038] For details, please refer to Figure 2-3 The hollow load-bearing beam plate 1 has two partition plates 14 in its inner cavity, which divide the inner cavity of the hollow load-bearing beam plate 1 into three parts. The two partition plates 14 are separated from each other by two springs 18 between the ends of the two partition plates 14 and the L-shaped clamping plate 4 on the same side. When the L-shaped clamping plate 4 clamps the assembled component, the springs 18 are in a contracted state. The hollow load-bearing beam plate 1 has a rotating roller 11 in the middle of its inner cavity. The upper and lower outer surfaces of the rotating roller 11 are equipped with steel wire ropes 17. The two steel wire ropes 17 pass through the partition plates 14 on the same side and are fixedly connected to the L-shaped clamping plate 4. The steel wire ropes 17 are wound up by rotating the rotating roller 11, thereby pulling the L-shaped clamping plate 4 towards the assembled component so that the L-shaped clamping plate 4 clamps and limits the assembled component. The hollow load-bearing beam plate 1 has a machine box 3 in the middle of its rear end. The machine box 3 has a motor 31 inside for controlling the rotating roller 11 to wind up the steel wire ropes 17.

[0039] Specifically, a cavity 15 communicating with the inner cavity of the housing 3 is opened at the bottom rear end of the hollow load-bearing beam plate 1. A transmission rod 12 is provided inside the cavity 15. The upper end of the transmission rod 12 penetrates the bottom wall of the inner cavity of the hollow load-bearing beam plate 1 and is fixedly connected to the rotating roller 11. A connecting belt 32 is provided between the outer surface of the transmission rod 12 and the output end of the motor 31. The motor 31 controls the transmission rod 12 in the cavity 15 to rotate through the connecting belt 32, thereby controlling the rotating roller 11 in the inner cavity of the hollow load-bearing beam plate 1 to rotate and wind up the wire rope 17, so as to avoid the wire rope 17 from directly winding onto the transmission rod 12 during the winding process, which would affect the normal operation of the transmission rod 12 and the connecting belt 32.

[0040] Specifically, the outer surface of the transmission rod 12 is uniformly provided with several rubber balls 13 to increase the friction between the transmission rod 12 and the connecting belt 32. This prevents excessive resistance when winding the wire rope 17, which could cause the connecting belt 32 to spin freely and fail to drive the transmission rod 12 to rotate. Therefore, the rubber balls 13 are provided to reduce the local contact area between the transmission rod 12 and the connecting belt 32, increase the pressure between them, and thus allow the connecting belt 32 to forcefully drag the transmission rod 12 to rotate.

[0041] For details, please refer to Figure 5-7 The clamping mechanism 6 includes a movable column 61 slidably connected in the mounting groove 1. The movable column 61 has an opening groove 611 and a flow ring groove 613 respectively opened in the middle and on the outer side of one end near the powerful suction cup 5. The length of the flow ring groove 613 is greater than the length of the opening groove 611. A water storage tank 612 is opened in the middle of the interior of the movable column 61. Multiple connecting grooves 614 connected to the flow ring groove 613 are opened on the inner surface of the water storage tank 612 away from the opening groove 611, so that the water stored in the water storage tank 612 can pass through the connecting grooves 614 under the extrusion of the subsequent extrusion plate 65 and flow into the flow ring groove 613.

[0042] Specifically, the end of the movable column 61 near the powerful suction cup 5 extends to the inner side of the powerful suction cup 5 and is provided with a turntable 62. The diameter of the turntable 62 is smaller than the outer diameter of the flow channel 41, so that the turntable 62 cannot completely block the air inlet channel 42 and does not hinder the airflow inside the powerful suction cup 5 into the flow channel 41 and the connecting channel 43. A threaded slot 625 penetrating its side wall is opened in the middle of the turntable 62. The threaded slot 625 and the open slot 611 are both provided with a threaded post 63. The threaded post 63 is threadedly connected in the threaded slot 625, so that the threaded post 63 can be used to press the assembled component. During the process, the turntable 62 rotates by retracting into the threaded slot 625 and the opening slot 611. A rectangular block 631 is provided at one end of the threaded column 63 located in the opening slot 611 to prevent the threaded column 63 from being restricted from rotating by the threaded slot 625 during the retraction of the threaded slot 625 and the opening slot 611. The end of the rectangular block 631 away from the threaded column 63 penetrates the side wall of the water storage tank 612 and is provided with a pressing plate 65 slidably connected in the water storage tank 612. A spring 66 is provided between the end of the pressing plate 65 away from the rectangular block 631 and the inner wall of the pressing plate 65.

[0043] Specifically, a connecting groove 622 is provided on the outer side of the turntable 62 near the moving column 61, which is used in conjunction with the flow ring groove 613, so that the water flow in the flow ring groove 613 can flow into the connecting groove 622. A moving groove 621 is provided on the inner wall of the connecting groove 622 away from the moving column 61, and the thickness of the moving groove 621 is greater than the thickness of the connecting groove 622. Multiple water inlet grooves 623 are evenly provided on the outer surface of the moving groove 621. The water flow entering the moving groove 621 and the connecting groove 622 is diverted through the water inlet grooves 623, so that the limited water flow can fill the multiple water inlet grooves 623. Then, the water is sprayed onto the contact surface between the powerful suction cup 5 and the assembled component through the water outlet groove 624 and the water spray pipe 68, so as to prevent the water flow from being sprayed out only through the water spray pipe 68 at the bottom of the turntable 62. The outer surface of the multiple water inlet grooves 623 is provided with water outlet grooves 624 that penetrate the outer surface of the turntable 62.

[0044] Specifically, the outer surface of the turntable 62 is uniformly provided with a plurality of water spray pipes 68 that are respectively connected to the water outlet 624 located on the same side. The part of the water spray pipes 68 away from the turntable 62 is bent and inclined towards the contact surface between the strong suction cup 5 and the assembled component. The inside of the moving groove 621 is provided with a blocking ring 64 for blocking the connecting groove 622. The end of the blocking ring 64 away from the moving column 61 and the inner wall of the moving groove 621 are provided with a plurality of springs 641 so that the water flow in the water storage tank 612 and the flow ring groove 613 under normal conditions cannot push open the blocking ring 64 and enter the moving groove 621.

[0045] Specifically, the thickness of the extrusion plate 65 is greater than the width of the connecting groove 2 614, so as to prevent the water in the water storage tank 612 from entering the space of the extrusion plate 65 away from the spring 3 66 through the transfer of the connecting groove 2 614, thereby affecting the return movement of the threaded column 63 and reducing the clamping force of the clamping mechanism 6 on the assembled component.

[0046] Specifically, a storage slot 69 is provided on the right side of the interior of the moving column 61. A flow channel 691, connecting to the water storage tank 612, is provided on the bottom of the inner wall of the storage slot 69 near the water storage tank 612. This allows the extrusion plate 65 to draw water from the storage slot 69 into the water storage tank 612 during retraction, replenishing the water flow in the water storage tank 612 for subsequent repeated operation. An installation slot 691 is provided on the rear inner wall of the flow channel 691. The inner wall of the installation slot 692 near the powerful suction cup 5 is an inclined surface, while the inner wall of the installation slot 692 away from the powerful suction cup 5 is a vertical surface. This ensures that the opening and closing mechanism 67 can only rotate towards the spring 66 and cannot rotate away from the spring 66. Therefore, when the extrusion plate 65 moves to extrude water from the water storage tank 612, the water in the water storage tank 612 will not flow through the flow channel 691. The second groove 691 enters the storage groove 69. The top and bottom walls of the second groove are provided with the third installation groove. The second installation groove is provided with the opening and closing mechanism 67. The end of the moving column 61 away from the powerful suction cup 5 is provided with a water inlet pipe 7 that communicates with the storage groove 69. The water inlet pipe 7 facilitates the subsequent replenishment of water into the storage groove 69, and limits the moving column 61 so that the moving column 61 will not rotate with the threaded column 63. This limits the threaded column 63 in the opposite direction so that when the threaded column 63 retracts back into the threaded empty groove 625 and the open groove 611, it can only force the turntable 62 to rotate in one direction. This allows the water jet from the spray pipe 68 to be completely sprayed onto the contact surface between the powerful suction cup 5 and the assembled component. The end of the water inlet pipe 7 away from the moving column 61 passes through the side wall of the first groove 43 and extends to the outside of the L-shaped clamp 4.

[0047] For details, please refer to Figure 8The opening and closing mechanism 67 includes a rotating rod 671 rotatably connected in two mounting slots 3. The diameter of the rotating rod 671 is smaller than the diameter of the mounting slot 3. The upper and lower parts of the outer surface of the rotating rod 671 are provided with baffles 674 for sealing the mounting slot 2. The upper and lower parts of the outer surface of the rotating rod 671 are provided with torsion springs 675 between them and the inner walls of the two mounting slots 3 located on the same side, so that after the extrusion plate 65 is pulled out, the rotating plate 672 can automatically rotate back and re-seal the flow slot 2 691. The middle part of the outer surface of the rotating rod 671 is provided with a rotating plate 672 for controlling the opening and closing of the flow slot 2 691. The end of the rotating plate 672 near the strong suction cup 5 is provided with a sealing pad 673 extending to reduce the gap. The angle between the rotating plate 672 and the side away from the rotating rod 671 and the sealing pad 673 is inclined, and one side of the inclined structure near the sealing pad 673 is located in the same vertical plane as the center line of the rotating rod 671.

[0048] Therefore, the specific implementation method of this embodiment is as follows:

[0049] After the device is placed on the prefabricated component, the motor 31 is started first, and then the transmission rod 12 and the rotating roller 11 are controlled to rotate through the connecting belt 32 to wind up the wire rope 17. Then the wire rope 17 pulls the two L-shaped clamps 4 to move towards the prefabricated component. During this process, the powerful suction cup 5 will contact the prefabricated component first. Then, under the obstruction of the sealing ring 51, the air inside the powerful suction cup 5 will rush into the connecting groove 43 through the air inlet groove 42, pushing the clamping mechanism 6 outward.

[0050] Then, the threaded post 63 on the clamping mechanism 6 will first contact the assembled component, so that the threaded post 63 is squeezed back into the opening slot 611 by the assembled component. Then, the threaded post 63 squeezes the water stored in the water storage tank 612 through the rectangular block 631 and the extrusion plate 65, so that the water in the water storage tank 612 flows into the flow ring groove 613 through the connecting groove 614, increasing the pressure in the flow ring groove 613, so that the water pushes away the blocking ring 64 and flows into the moving groove 621. After being diverted by the water inlet groove 623, it flows through the water outlet groove 624 and the spray. Water pipe 68 sprays onto the contact surface between the powerful suction cup 5 and the prefabricated component, sealing the gap between the contact surface of the powerful suction cup 5 and the prefabricated component for a second time, enhancing the suction force of the powerful suction cup 5 on the prefabricated component, thereby further increasing the structural stability between the powerful suction cup 5 and the prefabricated component. During the process of the threaded column 63 retracting the threaded slot 625 and the open slot 611, the threaded column 63 will also use the threaded connection with the threaded slot 625 to make the turntable 62 rotate so that the water flow can be completely sprayed onto the contact surface between the powerful suction cup 5 and the prefabricated component.

[0051] After the work is completed, the wire rope 17 is released so that the L-shaped clamp 4 is separated from the assembled component under the rebound action of the spring 18. During this process, manual assistance may be needed to pull out the powerful suction cup 5. After the threaded column 63 is separated from the assembled component, the pressing plate 65, the rectangular block 631 and the threaded column 63 will move outward to the initial position under the rebound action of the spring 3 66. When the pressing plate 65 moves back in the water storage tank 612, it will also pull the opening and closing mechanism 67 so that the rotating rod 671 and the rotating plate 672 rotate to open the flow channel 2 691, so that the water stored in the storage tank 69 can be replenished into the water storage tank 612 for subsequent repeated operations.

[0052] Example 2

[0053] This embodiment, based on Embodiment 1, adds an adjustment mechanism 2 to facilitate changing the angle of the assembled components transported to higher locations, making it easier to disassemble them from the device. Figure 9-10 As shown, the upper middle part of the hollow load-bearing beam plate 1 is provided with an adjustment mechanism 2 for changing the position of the component. The upper end of the adjustment mechanism 2 is provided with a lifting ring 20, which facilitates the crane to continue to use the lifting rope to lift the prefabricated component for transportation. The adjustment mechanism 2 includes a box 21 fixedly connected to the lower end of the lifting ring 20. The inner middle side of the box 21 is provided with a rotating column 25. The lower end of the rotating column 25 passes through the bottom wall of the lifting ring 20 and is fixedly connected to the hollow load-bearing beam plate 1. The upper part of the outer surface of the rotating column 25 and the middle part of the outer surface are respectively provided with a spur gear 26 and a spur gear 27. The front right side of the top wall of the box 21 is provided with a motor 22. The output end of the motor 22 is provided with a speed regulating mechanism 23 for changing the rotation speed of the rotating column 25 through a coupling. By setting the speed regulating mechanism 23, the speed when adjusting the angle of the prefabricated component is changed, so as to avoid the angle adjustment speed being too fast, which would cause the prefabricated component to be unable to be placed in the predetermined position normally.

[0054] For details, please refer to Figure 10 The speed regulating mechanism 23 includes a polygonal rod 231 rotatably connected to the bottom wall of the lifting ring 20. The polygonal rod 231 is connected between the coupling and the polygonal rod 231. A sleeve 232 is provided on the outer surface of the polygonal rod 231. The sleeve 232 slides up and down on the outer surface of the polygonal rod 231. A spur gear 233 meshes with a spur gear 26 at the upper part of the outer surface of the sleeve 232. A spur gear 234 meshes with a spur gear 27 at the lower part of the outer surface of the sleeve 232. A movable plate 235 is provided in the middle of the outer surface of the sleeve 232. A hydraulic rod 24 is fixedly connected to the movable plate 235 on the left side of the top wall of the lifting ring 20. By controlling the extension or retraction of the hydraulic rod 24, the sleeve 232 is driven to move up and down so that the spur gear 233 meshes with the spur gear 26 or the spur gear 234 meshes with the spur gear 27.

[0055] Specifically, the number of surface teeth on spur gear 26 is greater than that on spur gear 233. When spur gear 233 meshes with spur gear 26, the rotational speed of spur gear 26 can be reduced by the tooth ratio between spur gear 233 and spur gear 26, so that the assembled component can rotate to a suitable angle for lowering and disassembly. The number of surface teeth on spur gear 27 is equal to that on spur gear 234. When the assembled component deviates significantly from the expected angle, the speed regulating mechanism 23 can be lowered to separate spur gear 233 from spur gear 26, allowing spur gear 234 to mesh with spur gear 27 and restoring the normal rotational speed of the assembled component. When the error is small, the speed regulating mechanism 23 can be adjusted back to re-mesh with spur gear 26.

[0056] Therefore, the specific implementation method of this embodiment is as follows:

[0057] After the prefabricated component is transported to the designated location, motor 22 is started first. Then, the polygonal rod 231 controls the rotation of spur gear 234, which drives the meshing spur gear 27 to rotate together. This allows the prefabricated component to reduce the error between the prefabricated component and the predetermined angle at a relatively fast speed. When the angle error is small, the hydraulic rod 24 pulls the rotating column 25 and the sleeve 232 upward to separate spur gear 234 from spur gear 27, so that spur gear 233 meshes with spur gear 26, reducing the rotation speed of the prefabricated component. This makes it easier to adjust the prefabricated component to the predetermined state. Finally, it is lowered and disassembled from the device.
