Description

Technical Field

[0001] This application relates to the technical field of hoisting equipment, and in particular to a modular light steel exterior wall rotation amplitude control hoisting system. Background Technology

[0002] Modular light steel exterior walls are prefabricated building envelope components that use standardized light steel components as the framework and combine them with prefabricated functional modules (such as insulation layers, decorative panels, and pipeline integration units).

[0003] During production, the modular light steel exterior wall needs to be flipped to facilitate the processing of other wall surfaces. Currently, when flipping the wall, a lifting frame is typically installed at the end of the lifting rope on the lifting equipment. The lifting frame has symmetrically arranged clamping components, including two opposing clamping plates and clamping bolts that control the two clamping plates to move closer or further apart. During clamping, the clamping bolts control the two opposing clamping plates to move closer together until they are pressed against the upper and lower end faces of the exterior wall. Then, the lifting equipment is activated, causing the lifting rope to move the wall upwards, lifting the exterior wall away from the ground. Finally, the exterior wall is rotated to flip it over.

[0004] However, the exterior wall has a certain weight. When the horizontal exterior wall is flipped to a vertical position, the exterior wall and the plywood may slip under the action of gravity, which may cause the exterior wall to sway or even fall off in the air, thus affecting the stability of the flipping process and potentially causing serious safety accidents. Utility Model Content

[0005] To improve the stability of the exterior wall during rotation, this application provides a modular light steel exterior wall rotation amplitude control hoisting system.

[0006] This application provides a modular lightweight steel exterior wall rotation amplitude control hoisting system, which adopts the following technical solution:

[0007] A modular light steel exterior wall rotation control hoisting system includes a crane, wherein the crane is slidably equipped with hoisting ropes;

[0008] A lifting plate is disposed on the side of the lifting rope away from the crane, and mounting plates are symmetrically disposed on the side of the lifting plate away from the lifting rope;

[0009] The first clamping seat has multiple clamping seats and is rotatably disposed on the side opposite to the mounting plate, and clamping grooves are respectively opened on the side opposite to the first clamping seat;

[0010] The clamping plates are arranged opposite each other in the clamping groove, and a clamping space is formed between the upper and lower clamping plates. Control bolts that are threadedly connected to the first clamping seat are respectively rotatably connected to the opposite sides of the clamping plates.

[0011] There are multiple second clamping seats, which are staggered and spaced apart from the first clamping seats in the circumferential direction. Connecting ropes are respectively connected to the opposite side of the second clamping seats, and the connecting ropes slide through the first clamping seats.

[0012] A control component is disposed in the first clamping seat, and the control component controls the sliding of the connecting rope into and out of the first clamping seat.

[0013] By adopting the above technical solution, before the exterior wall is flipped, the lifting plate is moved to allow the exterior wall to slide into the clamping space. Then, the control worm gears on both sides are rotated simultaneously, causing the two second clamping seats to move closer together and clamp the exterior wall. Next, by rotating the control bolts, the clamping plates in the same group cooperate to clamp the exterior wall tightly. Afterward, the crane can be started, allowing the lifting rope to lift the exterior wall. When the wall is flipped and in a horizontal state, the clamping plates cooperate to support the wall; when the wall is flipped to a vertical state, the second clamping seats support the exterior wall, reducing the risk of slippage between the exterior wall and the clamping plates, which could cause the exterior wall to sway or even fall off in mid-air. This improves the stability of the exterior wall flipping process and reduces the possibility of safety accidents.

[0014] Optionally, the control assembly includes a control worm gear, a control worm, and a control shaft;

[0015] The control shaft is rotatably connected to the first clamping seat, and the connecting rope is connected to the control shaft on the side away from the second clamping seat, and the connecting rope is wrapped around the outer periphery of the control shaft;

[0016] The control worm gear is disposed on the outer periphery of the control shaft, and the control worm is rotatably connected to the first clamping seat. The control worm gear meshes with the control worm.

[0017] By adopting the above technical solution, and by setting the control worm gear to mesh with the control worm, the self-locking characteristic of the worm gear transmission is utilized to effectively reduce the possibility of the connecting rope becoming unexpectedly loose during hoisting, thereby improving the stability of the system.

[0018] Optionally, a connecting sleeve is slidably sleeved on the outer periphery of the control bolt, and the connecting sleeve is rotatably connected to the first clamping seat;

[0019] A linkage block is provided on the inner circumference of the connecting sleeve, and a linkage groove is provided on the outer circumference of the control bolt for the linkage block to slide axially.

[0020] The first clamping seat is provided with a transmission component. When the control shaft winds the connecting rope, the transmission component drives the connecting sleeve to rotate, so that the clamping plates move closer to each other.

[0021] By adopting the above technical solution, the linkage structure between the connecting sleeve and the control bolt enables the clamping plates to automatically move closer to each other when the control shaft winds the connecting rope, making it convenient for the clamping plates to clamp the outer wall.

[0022] Optionally, the transmission assembly includes a transmission gear and a connecting gear;

[0023] The transmission gear is disposed on the outer periphery of the control shaft, and the connecting gear is disposed on the outer periphery of the connecting sleeve. The connecting gear meshes with the transmission gear.

[0024] By adopting the above technical solution, the connecting gear meshes with the transmission gear, so that when the control shaft rotates, it can drive the connecting sleeve to rotate synchronously.

[0025] Optionally, the connecting gear is rotatably connected to the connecting sleeve, and a connecting groove surrounding the connecting sleeve is formed on the inner peripheral sidewall of the connecting gear;

[0026] The outer periphery of the connecting sleeve is provided with sliding teeth that slide in the connecting groove. The connecting gear is provided with a plurality of connecting teeth located in the connecting groove evenly arranged in the circumferential direction. The connecting teeth mesh with the sliding teeth, and the sliding teeth slide on the connecting teeth.

[0027] By adopting the above technical solution, when the clamping plate clamps the outer wall and there is a gap between the second clamping seat and the outer wall, the connecting teeth slide on the sliding teeth, so that the control shaft can continue to wind the connecting rope. At this time, the connecting sleeve and the connecting gear rotate relative to each other.

[0028] Optionally, a rotating shaft parallel to the control bolt is rotatably connected to the second clamping seat, with both ends of the rotating shaft protruding out of the second clamping seat;

[0029] Limiting plates are provided at both ends of the rotating shaft;

[0030] The outer circumference of the rotating shaft is provided with rotating teeth, and the second clamping seat is provided with a rotating groove that surrounds the rotating shaft and allows the rotating teeth to slide.

[0031] The second clamping seat is evenly provided with a plurality of limiting teeth along the circumference and in contact with the limiting teeth in the rotating groove. The rotating teeth mesh with the limiting teeth and slide on the limiting teeth.

[0032] By adopting the above technical solution, when the second clamping seat clamps the outer wall, rotating the rotating shaft causes the limiting plate to abut against the outer wall surface, which helps to improve the connection stability between the second clamping seat and the outer wall.

[0033] Optionally, the rotating shaft is provided with connecting screws at both ends, the limiting plate slides on the connecting screws, the connecting screws are threaded and provided with connecting nuts, and the limiting plate is located between the connecting nuts.

[0034] By adopting the above technical solution, the position of the limiting plate can be adjusted by rotating the connecting nut, which is beneficial for adapting to exterior walls of different thicknesses.

[0035] Optionally, the mounting plate is slidably connected with a pin, and the first clamping seat has a plug slot for inserting the pin.

[0036] By adopting the above technical solution, the pin is inserted into the insertion slot, so that the first clamping seat and the mounting plate can be temporarily fixed.

[0037] In summary, this application includes at least one of the following beneficial effects:

[0038] 1. When the wall is flipped, the wall is supported by the cooperation of the clamping plates when the wall is in a horizontal state; when the wall is flipped to a vertical state, the outer wall is supported by the second clamping seat, which reduces the risk of slippage between the outer wall and the clamping plate, which may cause the outer wall to sway or even fall off in the air. This helps to improve the stability of the outer wall flipping process and reduce the possibility of safety accidents.

[0039] 2. When the second clamping seat clamps the outer wall, rotating the rotating shaft causes the limiting plate to abut against the outer wall surface, which helps to improve the connection stability between the second clamping seat and the outer wall. Attached Figure Description

[0046] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0047] This application discloses a modular light steel exterior wall rotation amplitude control hoisting system.

[0048] Example 1

[0049] See Figure 1 The hoisting system includes a crane 1, on which a hoisting rope 11 is slidably connected. The crane 1 is the power source, and the hoisting rope 11 drives the exterior wall to rise and fall.

[0050] See Figure 1 and Figure 2 The hoisting system also includes a hoisting plate 12, a first clamping seat 2, and a clamping plate 22. The hoisting plate 12 is fixedly connected to the side of the hoisting rope 11 away from the crane 1. The side of the hoisting rope 11 away from the crane 1 can have a forked structure to improve the connection strength between the hoisting rope 11 and the hoisting plate 12. An installation plate 13 is fixedly connected to the side of the hoisting plate 12 away from the hoisting rope 11. There are two installation plates 13, which are symmetrically arranged. The hoisting plate 12 and the installation plate 13 are supported in an inverted "U" shape.

[0051] There are two first clamping seats 2, each rotatably connected to the opposite side of the mounting plate 13. Each of the two opposite sides of the first clamping seats 2 has a clamping groove 21. There are two sets of clamping plates 22, each set corresponding to one first clamping seat 2. Each set has two clamping plates 22 arranged vertically opposite each other, and the clamping plates 22 are located within the clamping grooves 21. A clamping space 221 is formed between two clamping plates 22 in the same set. Control bolts 23 are rotatably connected to the opposite sides of two opposite clamping plates 22 in the same set, and the control bolts 23 are threadedly connected to the first clamping seats 2. Before hoisting the exterior wall, the control bolt 23 is rotated to move the two clamping plates 22 in the same group away from each other, so that the width of the clamping space 221 is greater than the thickness of the exterior wall. Then, the hoisting plate 12 is moved so that the clamping space 221 is aligned with the exterior wall. Then, the hoisting plate 12 is moved horizontally so that the exterior wall slides into the clamping space 221. Finally, the control bolt 23 is reversed to move the two clamping plates 22 in the same group closer to each other until the clamping plates 22 are pressed against the exterior wall surface, thus realizing the connection between the first clamping seat 2 and the exterior wall.

[0052] See Figure 2 and Figure 3 The mounting plate 13 is slidably provided with a pin 131, and the first clamping seat 2 has a insertion groove 24 on the side facing the mounting plate 13. When the first clamping seat 2 does not need to be rotated, the pin 131 is inserted into the insertion groove 24, and the mounting plate 13 and the first clamping seat 2 are temporarily fixed at this time; when the first clamping seat 2 needs to be rotated, the pin 131 is driven to slide away from the insertion groove 24.

[0053] The hoisting system also includes second clamping seats 3 and a control component 4. Multiple second clamping seats 3 are arranged opposite each other. In this embodiment, there are two second clamping seats 3, with the first clamping seat 2 and the second clamping seats 3 staggered circumferentially. During clamping, the opposing sides of the two clamping seats abut against the opposite vertical sidewalls of the exterior wall. Connecting ropes 31 are fixedly connected to the opposite sides of the second clamping seats 3, and the connecting ropes 31 slide through the first clamping seat 2 on the side away from the second clamping seat 3. The control component 4 is located on the first clamping seat 2. When the second clamping seats 3 need to clamp the wall, the control component 4 controls the connecting ropes 31 to slide into the first clamping seat 2. At this time, the two opposing second clamping seats 3 move closer to each other and cooperate to clamp the exterior wall. When the second clamping seats 3 need to release the wall, the control component 4 controls the connecting ropes 31 to slide out of the first clamping seat 2.

[0054] The control assembly 4 includes a control worm gear 41, a control worm 42, and a control shaft 43. The control shaft 43 corresponds one-to-one with the first clamping seat 2, and is rotatably connected to the first clamping seat 2, passing through the clamping groove 21. A connecting rope 31 is fixedly connected to the outer periphery of the control shaft 43 on the side away from the second clamping seat 3, and is wound around the outer periphery of the control shaft 43. The control worm gear 41 is fixedly connected to the outer periphery of the control shaft 43 and is rotatably connected to the first clamping seat 2. The control worm 42 is rotatably connected to the first clamping seat 2, and the control worm gear 41 and the control worm 42 mesh, satisfying self-locking parameters. When the worm gear 42 rotates, the control shaft 43 rotates via the control worm wheel 41, causing the control shaft 43 to wind the connecting rope 31 and move the relative second clamping seats 3 closer together. When the worm gear 42 rotates in reverse, the control shaft 43 rotates in the opposite direction via the control worm wheel 41, causing the control shaft 43 to release the connecting rope 31, at which point the relative second clamping seats 3 loosen from the outer wall. A drive motor can also be installed and fixed on the first clamping seat 2. The output shaft of the drive motor is fixedly connected to the control worm gear 42. When the drive motor starts, it drives the control worm gear 42 to rotate.

[0055] The implementation principle of the modular light steel exterior wall rotation amplitude control hoisting system in Embodiment 1 of this application is as follows:

[0056] Before the exterior wall is flipped, the lifting plate 12 is moved to allow the exterior wall to slide into the clamping space 221. Then, the control worm gears 42 on both sides are rotated simultaneously, causing the two second clamping seats 3 to move closer together and clamp the exterior wall. Then, by rotating the control bolt 23, the clamping plates 22 in the same group cooperate to clamp the exterior wall. After that, the crane 1 can be started, causing the lifting rope 11 to lift the exterior wall. Then, the pin 131 can be removed to flip the wall. When the wall is flipped, the wall surface is supported by the cooperation of the clamping plates 22 when the wall surface is in a horizontal state; when the wall surface is flipped to a vertical state, the second clamping seats 3 support the exterior wall, reducing the risk of slippage between the exterior wall and the clamping plates 22, which could cause the exterior wall to sway or even fall off in the air. This helps to improve the stability of the exterior wall flipping process and reduces the possibility of safety accidents.

[0057] Example 2

[0058] See Figure 2 and Figure 3The difference between Embodiment 2 and Embodiment 1 is that: a rotating shaft 32 is rotatably connected to the second clamping seat 3, and the rotating shaft 32 is parallel to the control bolt 23. Both ends of the rotating shaft 32 protrude outside the second clamping seat 3, and connecting screws 322 are fixedly connected to both ends of the rotating shaft 32. The connecting screws 322 and the rotating shaft 32 are coaxially arranged. A limiting plate 33 is slidably connected to the connecting rod, and the limiting plate 33 corresponds one-to-one with the connecting screw 322. A connecting nut 323 is threaded onto the connecting screw 322. Each connecting screw 322 has two connecting nuts 323 arranged opposite to each other, and the limiting plate 33 is located between the two opposite connecting nuts 323.

[0059] See Figure 4 A rotating tooth 321 is fixedly connected to the outer periphery of the rotating shaft 32. The second clamping seat 3 has a rotating groove 34 surrounding the rotating shaft 32, and the rotating tooth 321 is slidably connected within the rotating groove 34. A limiting tooth 35 is fixedly connected to the second clamping seat 3. The limiting tooth 35 is located on the groove wall of the rotating groove 34 away from the rotating shaft 32. There are multiple limiting teeth 35, evenly arranged circumferentially. The rotating tooth 321 meshes with the limiting tooth 35. Both the limiting tooth 35 and the rotating tooth 321 have a triangular tooth structure and are made of a material with elastic deformation capability, such as plastic or rubber. The rotating tooth 321 and the limiting tooth 35 are rotatably connected.

[0060] The implementation principle of a modular light steel exterior wall rotation amplitude control hoisting system according to Embodiment 2 of this application is as follows:

[0061] Before the two second clamping seats 3 clamp the outer wall together, the distance between the two opposing limiting plates 33 is adjusted by rotating the connecting nut 323 so that the distance between the two limiting plates 33 adapts to the thickness of the outer wall. When the two second clamping seats 3 clamp the outer wall together, rotating the rotating shaft 32 causes the limiting plates 33 to flip and abut against the opposite sides of the outer wall, which helps to improve the connection stability between the second clamping seats 3 and the outer wall, and further improves the stability when the outer wall flips.

[0062] Example 3

[0063] See Figure 3 and Figure 5The difference between Embodiment 3 and Embodiment 2 is that: a connecting sleeve 5 is slidably sleeved on the outer periphery of the control bolt 23, and one end of the connecting sleeve 5 is rotatably connected to the first clamping seat 2. A linkage block 51 is fixedly connected to the inner periphery of the connecting sleeve 5, and a linkage groove 231 is formed on the outer periphery of the control bolt 23, extending axially along the control bolt 23. In use, the linkage block 51 is slidably connected within the linkage groove 231. When the connecting sleeve 5 rotates, the control bolt 23 rotates through the linkage block 51. Since the control bolt 23 is threadedly connected to the first clamping seat 2, the control bolt 23 slides within the connecting sleeve 5 at this time.

[0064] The first clamping seat 2 is equipped with a transmission assembly 6. When the control shaft 43 winds the connecting rope 31, the transmission assembly 6 drives the connecting sleeve 5 to rotate, causing the relative clamping plates 22 to move closer or further apart. The transmission assembly 6 includes a transmission gear 61 and a connecting gear 62. The transmission gear 61 is fixedly connected to the outer periphery of the control shaft 43. The connecting gear 62 has a sliding hole in the middle, and the connecting sleeve 5 slides through the sliding hole. The connecting gear 62 and the transmission gear 61 mesh with each other.

[0065] A connecting groove 622 extending circumferentially is formed on the peripheral wall of the sliding hole, surrounding the connecting sleeve 5. A sliding tooth 52 is fixedly connected to the outer periphery of the connecting sleeve 5, protruding into the connecting groove 622 and sliding within it. A connecting gear 62 is fixedly connected to a connecting tooth 621, located on the groove wall of the connecting groove 622 away from the connecting sleeve 5. Multiple connecting teeth 621 are evenly distributed circumferentially, and they mesh with the sliding tooth 52. Both the sliding tooth 52 and the connecting tooth 621 have a triangular tooth structure and are made of a material with elastic deformation capability, such as plastic or rubber. The sliding tooth 52 and the connecting tooth 621 are rotatably connected.

[0066] The implementation principle of a modular light steel exterior wall rotation amplitude control hoisting system according to Embodiment 3 of this application is as follows:

[0067] When the control shaft 43 rotates, the connecting gear 62 and the transmission gear 61 cooperate with each other, causing the connecting sleeve 5 to rotate, which in turn drives the control bolt 23 to rotate, facilitating the clamping plate 22 to clamp the outer wall. When the clamping plate 22 clamps the outer wall and there is a gap between the second clamping seat 3 and the outer wall, the connecting tooth 621 slides on the sliding tooth 52, allowing the control shaft 43 to continue winding the connecting rope 31. At this time, the connecting sleeve 5 and the connecting gear 62 rotate relative to each other.

[0068] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
