Description

Technical Field

[0001] This invention relates to the field of thermal insulation building materials technology, specifically to a self-adaptive hoisting and alignment device for prefabricated wall panels. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods.

[0003] Currently, prefabricated buildings typically require hoisting equipment for installation assistance. However, existing hoisting equipment still has certain shortcomings. Hoisting equipment often uses cables to connect to the wall panels. During hoisting, the wall panels sway with the cables, preventing the positioning holes from quickly connecting with the ground positioning ribs, thus affecting installation efficiency. Furthermore, excessive cable swaying during hoisting can easily cause the wall panels to injure workers assisting with the hoisting, resulting in low hoisting stability. Summary of the Invention

[0004] This invention provides a prefabricated wall panel self-adaptive hoisting and alignment device to solve the problems of low installation efficiency and low stability of existing hoisting devices that use cables to connect to the wall panels.

[0005] In a first aspect, the present invention provides a prefabricated wall panel adaptive hoisting and alignment device, comprising: A tracked trolley, wherein a lifting mechanism is installed at the forward end of the tracked trolley; The hoisting mechanism includes a hoisting structure and an auxiliary hoisting structure. The hoisting structure is installed on the lifting end of the hoisting mechanism, and the auxiliary hoisting structure is installed on the hoisting structure. The hoisting structure includes a first housing, a drive assembly, an adaptive clamping assembly, and a power tangential assembly. The first housing is connected to the lifting end of the lifting mechanism. The drive assembly, the adaptive clamping assembly, and the power tangential assembly are all mounted on the first housing. The drive end of the drive assembly is connected to the adaptive clamping assembly, and the power tangential assembly is mounted on one side of the drive assembly. The auxiliary hoisting structure includes a second housing, a positioning component, a lateral adjustment component, and a longitudinal adjustment component. The second housing is located on the side of the first housing away from the lifting mechanism. The lateral adjustment component is located between the first housing and the second housing. The longitudinal adjustment component is located on the second housing. The positioning component is located on the moving end of the longitudinal adjustment component. The drive assembly is rotatably mounted on the first housing, and the power tangential assembly is adapted to drive the drive assembly to rotate, so that the drive assembly has a clamping state in which the drive end is connected to the adaptive clamping assembly, and an adjusting state in which the drive end is connected to the lateral adjusting assembly.

[0006] Beneficial effects: Through the lifting mechanism set on the tracked trolley, when the tracked trolley moves to the vicinity of the wall panel, the lifting mechanism can drive the lifting mechanism to approach the wall panel. Thus, under the drive of the drive component, the self-adaptive clamping component can clamp both ends of the wall panel, and the power tangential component can drive the drive component to rotate, so that the drive end of the drive component is connected to the lateral adjustment component, and the lateral adjustment component is driven to adjust the distance between the first housing and the second housing, so that the positioning component can abut against the surface of the wall panel under the drive of the longitudinal adjustment component, thereby realizing three-point clamping of the wall panel, which is beneficial to improving the lifting stability.

[0007] In one optional embodiment, the adaptive clamping assembly includes a clamping seat, at least two pulleys, a clamping arm, and a disc chuck. The clamping seat is disposed on the first housing. The two pulleys are slidably disposed at both ends of the clamping seat. One end of the clamping arm is rotatably connected to the pulleys, and the other end is connected to the disc chuck. Both of the pulley carriages are connected to the drive end of the drive assembly, so that under the drive of the drive assembly, the two pulley carriages drive the clamping arm and the disc chuck to move closer to or further away from each other.

[0008] Beneficial Effects: By setting an adaptive clamping assembly including a clamping base, two pulleys, a clamping arm, and a disc chuck, the clamping base is mounted on the first housing. The two pulleys are slidably mounted at opposite ends of the clamping base. One end of the clamping arm is rotatably connected to a pulley, and the other end is connected to the disc chuck. The drive end of the drive assembly is connected to the two pulleys. Driven by the drive assembly, the two pulleys can move the clamping arm and the disc chuck closer together or further apart. When the two pulleys approach each other, the two disc chucks contact both ends of the wall panel, clamping them. When the two pulleys move apart, the two disc chucks separate from the wall panel, releasing it. It should be noted that because the clamping arm and pulleys are rotatably connected, when the disc chuck contacts the wall panel, the clamping arm can rotate relative to the pulleys, allowing for surface contact rather than line contact, increasing the friction between the disc chuck and the wall panel.

[0009] In one optional embodiment, the drive assembly includes a first drive member and at least two winding units. The first drive member and the two winding units are both disposed on the first housing. The two winding units are symmetrically arranged. The drive end of the first drive member is connected to the two winding units. Each winding unit is connected to a pulley cart to drive the two pulley carts to move closer to or further away from each other.

[0010] Beneficial effects: By setting the drive assembly to include a first drive member and two winding units, the first drive member in this embodiment is a servo motor or a variable frequency motor. The first drive member and the two winding units are both set on the first housing. The two winding units are symmetrically arranged. The drive end of the first drive member is connected to the two winding units. Each winding unit is connected to a pulley. Thus, under the drive of the first drive member, the two winding units can simultaneously drive the two pulleys to move closer or further away from each other, thereby realizing the clamping or releasing of the two ends of the wall panel.

[0011] In one optional embodiment, any of the winding units includes a winding roller, a turbine, a worm gear, a cable, a first sprocket, a second sprocket, and a chain. The winding roller and the turbine are spaced apart and rotatably mounted on the first housing. The first sprocket is mounted on the winding roller, and the second sprocket is mounted on the turbine. The chain is mounted between the first sprocket and the second sprocket. The worm gear is meshed with the turbine, and one end of the worm gear is provided with a U-shaped seat. The U-shaped seat is adapted to connect to the driving end of the first driving member so that the worm gear rotates under the drive of the first driving member. The cable is wound on the winding roller, and one end of the cable is connected to the winding roller, and the other end is connected to the pulley carriage.

[0012] Beneficial effects: By configuring each winding unit to include a winding roller, a worm gear, a cable, a first sprocket, a second sprocket, and a chain, wherein the winding roller and the worm gear are spaced apart and both are rotatably mounted on the first housing, the first sprocket is mounted on the winding roller, the second sprocket is mounted on the worm gear, the chain is mounted between the first and second sprockets, the worm gear is meshed with the worm gear, and one end of the worm gear is provided with a U-shaped seat, which can be connected to the drive end of the first drive component (the drive component is in a clamping state). In the first driving component, the U-shaped seat can drive the worm gear to rotate, which in turn drives the turbine to rotate. The turbine then drives the winding roller to rotate via a chain. A rope is wound on the winding roller, with one end connected to the winding roller and the other end connected to the pulley. As the winding roller rotates, the rope will either tighten or loosen onto the winding roller. When it tightens, the two pulleys will move closer to each other, and when it loosens, the two pulleys will move away from each other. In this way, the two pulleys can be driven simultaneously.

[0013] In one optional embodiment, the positioning component includes a first telescopic arm, a second telescopic arm, and a positioning plate. The first telescopic arm is disposed on the second housing, the second telescopic arm is slidably disposed on the first telescopic arm, the positioning plate is disposed at the end of the second telescopic arm away from the first telescopic arm, and the longitudinal adjustment component is disposed on the first telescopic arm, with its moving end connected to the second telescopic arm.

[0014] Beneficial effects: By setting the positioning component including a first telescopic arm, a second telescopic arm, and a positioning plate, wherein the first telescopic arm is mounted on the second housing, the second telescopic arm is slidably mounted on the first telescopic arm, the positioning plate is mounted on the end of the second telescopic arm away from the first telescopic arm, and the longitudinal adjustment component is mounted on the first telescopic arm, with the moving end of the longitudinal adjustment component connected to the second telescopic arm, the second telescopic arm can move relative to the first telescopic arm under the drive of the longitudinal adjustment component, thereby allowing the positioning plate to contact the center position of the wall panel surface. This provides stable support for the wall panel during installation, facilitating the positioning and installation of the wall panel.

[0015] In one optional embodiment, the longitudinal adjustment assembly includes a slide rod, a slide block, a first threaded rod, a threaded slide block, and a second driving member. The slide rod and the first threaded rod are respectively disposed on both sides of the first telescopic arm. The slide block is slidably disposed on the slide rod. The threaded slide block is threadedly connected to the first threaded rod. Both the slide block and the threaded slide block are connected to the second telescopic arm. The driving end of the second driving member is connected to the end of the first threaded rod to drive the first threaded rod to rotate.

[0016] Beneficial effects: By setting the longitudinal adjustment component including a slide rod, a slide block, a first threaded rod, a threaded slide block, and a second driving member, the second driving member in this embodiment is a servo motor or a variable frequency motor. The slide rod and the first threaded rod are respectively set on both sides of the first telescopic arm. The slide block is slidably set on the slide rod, and the threaded slide block is threadedly connected to the first threaded rod. Both the slide block and the threaded slide block are connected to the second telescopic arm. The driving end of the second driving member is connected to the end of the first threaded rod. Thus, under the drive of the second driving member, the first threaded rod can rotate, causing the threaded slide block to move on it. This causes the second telescopic arm to move relative to the first telescopic arm through the threaded slide block, thereby enabling the positioning plate to move in the vertical direction. When the second telescopic arm moves, the slide block will move relative to the slide rod under the drive of the second telescopic arm, providing a guiding effect for the movement of the second telescopic arm.

[0017] In one optional embodiment, the lateral adjustment assembly includes an internal threaded rod, a second threaded rod, and a plurality of telescopic rods. One end of the internal threaded rod is connected to the first telescopic arm, and the other end is threadedly connected to the second threaded rod. A connecting seat is provided at the end of the second threaded rod away from the internal threaded rod. An arc-shaped groove is provided on the connecting seat, which is adapted to connect to the driving end of the first driving member. All the telescopic rods are spaced apart between the first telescopic arm and the second housing.

[0018] Beneficial effects: By setting a lateral adjustment component including an internal threaded rod, a second threaded rod, and several telescopic rods, one end of the internal threaded rod is connected to the first telescopic arm, and the other end is threadedly connected to the second threaded rod. The end of the second threaded rod away from the internal threaded rod is provided with a connecting seat, and the connecting seat has an arc-shaped groove. The connecting seat can be connected to the driving end of the first driving component through the arc-shaped groove (when the driving component is in the adjustment state). All the telescopic rods are spaced apart between the first telescopic arm and the second housing. In this way, under the drive of the first driving component, the connecting seat can drive the second threaded rod to rotate, so that the internal threaded rod can move closer to or away from the second threaded rod, thereby realizing the adjustment of the distance between the first telescopic arm and the second housing. The telescopic rods can ensure the stability of the movement of the first telescopic arm.

[0019] In one optional embodiment, the power tangential assembly includes a third drive member, a movable seat, a third screw, a gear, and a rotating rod. The third drive member is disposed on the first housing, the movable seat is slidably disposed on the first housing, one end of the third screw is connected to the drive end of the third drive member, and the other end is threadedly connected to the movable seat. The movable seat is provided with a rack, and the gear is meshed with the rack. One end of the rotating rod is connected to the gear, and the other end is rotatably connected to the first drive member.

[0020] Beneficial effects: By setting the power tangential assembly including a third driving member, an action, a third screw, a gear, and a rotating rod, the third driving member in this embodiment is a servo motor or a variable frequency motor. The third driving member is set on the first housing, and the moving seat is slidably set on the first housing. One end of the third screw is connected to the driving end of the third driving member, and the other end is threadedly connected to the moving seat. Thus, under the drive of the third driving member, the third screw can rotate and drive the moving seat to move on it. The moving seat is provided with a rack, and the gear is meshed with the rack. One end of the rotating rod is connected to the gear, and the other end is rotatably connected to the first driving member. Thus, when the moving seat moves, the gear will rotate under the action of the rack, thereby enabling the gear to drive the rotating rod to rotate, and the rotating rod to drive the first driving member to rotate. In this way, the first driving member can be switched between the clamping state and the pitch adjustment state.

[0021] In one optional embodiment, the drive assembly further includes a rotating shaft, one end of which is connected to the drive end of the first drive member, and the other end of which is provided with an arc-shaped rotating head. In the adjustable state, the arc-shaped rotating head is adapted to engage with the arc-shaped slot. The rotating shaft is also provided with a ball seat, and the U-shaped seat is provided with a spherical groove adapted to the ball seat. In the clamping state, the arc-shaped rotating head is adapted to connect with the U-shaped seat, and the ball seat is adapted to be rolled within the spherical groove.

[0022] Beneficial effects: By including a rotating shaft in the drive assembly, one end of the rotating shaft is connected to the drive end of the first drive member, and the other end is provided with an arc-shaped rotating head. In the adjustable state, the arc-shaped rotating head can engage with the arc-shaped slot, so that the first drive member can drive the second screw to rotate through the rotating shaft. In addition, the rotating shaft is also provided with a ball seat, and the U-shaped seat is provided with a spherical groove that matches the ball seat. So in the clamping state, the arc-shaped rotating head can connect with the U-shaped seat, and the ball seat can be placed in the spherical groove. Thus, when the first drive member drives the worm to rotate through the arc-shaped rotating head, an effective torque transmission lock is formed between the ball seat and the spherical groove, so that the rotating shaft, ball seat and U-shaped seat temporarily become a rigid whole, completely suppressing the inherent swing freedom of the ball seat in the spherical groove.

[0023] In one optional embodiment, the lifting mechanism includes a hydraulic lifting seat and a sliding arm. The hydraulic lifting seat is disposed on the forward end of the tracked trolley, and one end of the sliding arm near the hydraulic lifting seat is slidably disposed on the hydraulic lifting seat. The other end of the sliding arm away from the hydraulic lifting seat is connected to the hoisting mechanism.

[0024] Beneficial effects: By setting up a lifting mechanism including a hydraulic lifting seat and a sliding arm, wherein the hydraulic lifting seat is set on the forward end of the tracked trolley and is driven by one or more hydraulic cylinders, and has a built-in high-precision displacement sensor, the high-precision displacement sensor is used to provide real-time feedback on the lifting height, and the end of the sliding arm close to the hydraulic lifting seat is slidably set on the hydraulic lifting seat, while the end away from the hydraulic lifting seat is connected to the hoisting mechanism, the lifting of the hoisting mechanism can be realized through the hydraulic lifting seat and the sliding arm.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of 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, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The following is combined with Figures 1 to 9 The following describes embodiments of the present invention.

[0030] According to embodiments of the present invention, in one aspect, a self-adaptive hoisting and alignment device for prefabricated wall panels is provided, such as... Figures 1 to 9 As shown, the system includes a tracked trolley 1 and a lifting mechanism 2. The tracked trolley 1 has a lifting mechanism installed at its forward end. The lifting mechanism 2 includes a lifting structure and an auxiliary lifting structure. The lifting structure is mounted on the lifting end of the lifting mechanism, and the auxiliary lifting structure is mounted on the lifting structure. The lifting structure includes a first housing 21, a drive assembly 22, an adaptive clamping assembly 23, and a power tangential assembly 24. The first housing 21 is connected to the lifting end of the lifting mechanism. The drive assembly 22, the adaptive clamping assembly 23, and the power tangential assembly 24 are all mounted on the first housing 21. The drive end of the drive assembly 22 is connected to the adaptive clamping assembly 23, and the power tangential assembly 24 is located on one side of the drive assembly 22. The auxiliary lifting mechanism 2... The hoisting structure includes a second housing 25, a positioning component 26, a lateral adjustment component 27, and a longitudinal adjustment component 28. The second housing 25 is located on the side of the first housing away from the lifting mechanism. The lateral adjustment component 27 is located between the first housing and the second housing 25. The longitudinal adjustment component 28 is located on the second housing 25. The positioning component 26 is located on the moving end of the longitudinal adjustment component 28. The drive component 22 is rotatably mounted on the first housing 21. The power tangential component 24 is adapted to drive the drive component 22 to rotate, so that the drive component 22 has a clamping state where the drive end is connected to the self-adaptive clamping component 23, and an adjustment state where the drive end is connected to the lateral adjustment component 27.

[0031] The prefabricated wall panel adaptive hoisting and positioning device described above uses a hoisting mechanism 2 mounted on a tracked trolley 1. The tracked trolley 1 has a lifting mechanism installed at its forward end. The hoisting mechanism 2 includes a hoisting structure and an auxiliary hoisting structure. The hoisting structure is mounted on the lifting end of the lifting mechanism, and the auxiliary hoisting structure is mounted on the hoisting structure. When a wall panel needs to be hoisted, the tracked trolley 1 can carry the hoisting mechanism 2 to the vicinity of the wall panel. The lifting mechanism then brings the hoisting mechanism 2 close to the wall panel so that it can clamp the wall panel. When the hoisting mechanism 2 clamps the wall panel, the lifting mechanism can lift the hoisting mechanism 2 to move the wall panel away from the ground, thus achieving the hoisting of the wall panel. This allows the tracked trolley 1 to move the wall panel.

[0032] It should be noted that the tracked trolley 1 is the mobile base and load-bearing platform of the entire device. It adopts a tracked walking mechanism, which has significant advantages over wheeled structures, such as low ground pressure, high traction, flexible steering, and strong adaptability to complex ground conditions at the construction site. This not only ensures that the device can move stably to the wall panel stacking area, but also ensures the accuracy and stability when making micro-adjustments at the installation position.

[0033] Specifically, the hoisting structure includes a first housing 21, a drive assembly 22, an adaptive clamping assembly 23, and a power tangential assembly 24. The drive assembly 22, the adaptive clamping assembly 23, and the power tangential assembly 24 are all mounted on the first housing 21. The drive end of the drive assembly 22 is connected to the adaptive clamping assembly 23 so that when the tracked trolley 1 moves near the wall panel, the drive assembly 22 can drive the adaptive clamping assembly 23 to clamp both ends of the wall panel. The power tangential assembly 24 is located on one side of the drive assembly 22, and its drive end is connected to the drive assembly 22 to drive the drive assembly 22 to rotate.

[0034] The auxiliary hoisting structure includes a second housing 25, a positioning assembly 26, a lateral adjustment assembly 27, and a longitudinal adjustment assembly 28. The second housing 25 is located on the side of the first housing 21 furthest from the lifting mechanism. The longitudinal adjustment component 28 is mounted on the second housing 25, and the positioning component 26 is mounted on the moving end of the longitudinal adjustment component 28. Driven by the longitudinal adjustment component 28, the positioning component 26 can move vertically, allowing it to contact the wall panel surface. Thus, when the self-adaptive clamping component 23 clamps both ends of the wall panel, the positioning component 26 then contacts the wall panel surface, forming a three-point clamping mechanism for the wall panel, which improves the clamping stability of the hoisting mechanism 2. The lateral adjustment component 27 is mounted between the first housing 21 and the second housing 25 to adjust the distance between them. Since the positioning component 26 is mounted on the second housing 25, the lateral adjustment component 27 can adjust the distance between the first housing 21 and the second housing 25 for different wall panels, ensuring that the positioning component 26 always contacts the wall panel surface, thus improving the versatility of the hoisting mechanism 2.

[0035] In addition, the drive assembly 22 is specifically rotatably mounted on the first housing 21, so that the power tangential assembly 24 can drive the drive assembly 22 to rotate relative to the first housing 21. This allows the drive assembly 22 to have a clamping state where the drive end is connected to the adaptive clamping assembly 23, and an adjusting state where the drive end is connected to the lateral adjusting assembly 27. In the clamping state, the drive end of the drive assembly 22 can drive the adaptive clamping assembly 23 to clamp both ends of the wall panel. In the adjusting state, the drive assembly 22 can drive the lateral adjusting assembly 27 to adjust the distance between the first housing 21 and the second housing 25, so that the positioning assembly 26 can contact the surface of the wall panel under the drive of the longitudinal adjusting assembly 28.

[0036] It should be noted that since the hoisting mechanism 2 is mounted on the tracked trolley 1 via a lifting mechanism, the lifting and lowering of the hoisting mechanism 2 is achieved through the lifting mechanism, while the clamping of the wall panel is achieved through the hoisting mechanism 2. Therefore, when the hoisting mechanism 2 clamps the wall panel and the tracked trolley 1 moves, the hoisting mechanism 2 will not sway, and consequently, the wall panel will not sway. This helps to improve the stability of the hoisting. Furthermore, because the wall panel will not sway during hoisting and movement, the wall panel can be quickly aligned during installation, which helps to improve the installation efficiency of the wall panel.

[0037] In summary, by using the lifting mechanism 2 mounted on the tracked trolley 1, when the tracked trolley 1 moves to the vicinity of the wall panel, the lifting mechanism can drive the lifting mechanism 2 to approach the wall panel. Thus, under the drive of the drive assembly 22, the self-adaptive clamping assembly 23 can clamp both ends of the wall panel, and the power tangential assembly 24 can drive the drive assembly 22 to rotate, so that the drive end of the drive assembly 22 is connected to the lateral adjustment assembly 27, and the lateral adjustment assembly 27 is driven to adjust the distance between the first housing 21 and the second housing 25, so that the positioning assembly 26 can abut against the surface of the wall panel under the drive of the longitudinal adjustment assembly 28, thereby achieving three-point clamping of the wall panel, which is beneficial to improving the lifting stability.

[0038] In one embodiment, such as Figure 3 As shown, the adaptive clamping assembly 23 includes a clamping base 231, at least two pulley carriages 232, a clamping arm 233, and a disc chuck 234. The clamping base 231 is disposed on the first housing 21. The two pulley carriages 232 are slidably disposed at both ends of the clamping base 231. One end of the clamping arm 233 is rotatably connected to the pulley carriage 232, and the other end is connected to the disc chuck 234. Both pulley carriages 232 are connected to the driving end of the driving assembly 22, so that under the drive of the driving assembly 22, the two pulley carriages 232 drive the clamping arm 233 and the disc chuck 234 to move closer to each other or further away from each other.

[0039] The prefabricated wall panel adaptive hoisting and alignment device described above, by setting an adaptive clamping assembly 23 including a clamping seat 231, two pulleys 232, a clamping arm 233, and a disc chuck 234, wherein the clamping seat 231 is set on the first housing 21, the two pulleys 232 are respectively slidably set at opposite ends of the clamping seat 231, one end of the clamping arm 233 is rotatably connected to the pulley 232, and the other end is connected to the disc connector, and the driving end of the driving assembly 22 is connected to the two pulleys 232. Thus, under the drive of the driving assembly 22, the two pulleys 232 can drive the clamping arm 233 and the disc chuck 234 to move closer or further away from each other. When the two pulleys 232 move closer to each other, the two disc chucks 234 can contact the two ends of the wall panel and achieve clamping of the two ends of the wall panel, and when the two pulleys 232 move further away from each other, the two disc chucks 234 separate from the wall panel to release the wall panel. It should be noted that since the clamping arm 233 and the pulley 232 are rotatably connected, when the disc chuck 234 contacts the wall panel, the clamping arm 233 can rotate relative to the pulley 232 so that the disc chuck 234 and the wall panel can achieve surface contact rather than line contact, thereby increasing the friction between the disc chuck 234 and the wall panel.

[0040] In one embodiment, such as Figure 3 As shown, the drive assembly 22 includes a first drive member 221 and at least two winding units 222. The first drive member 221 and the two winding units 222 are both disposed on the first housing 21. The two winding units 222 are symmetrically arranged. The drive end of the first drive member 221 is connected to the two winding units 222. Each winding unit 222 is connected to a pulley carriage 232 to drive the two pulley carriages 232 to move closer to or further away from each other.

[0041] The prefabricated wall panel adaptive hoisting and positioning device described above, by setting a drive component 22 including a first drive component 221 and two winding units 222, wherein the first drive component 221 is a servo motor or a variable frequency motor in this embodiment, wherein the first drive component 221 and the two winding units 222 are both set on the first housing 21, and the two winding units 222 are symmetrically arranged, the drive end of the first drive component 221 is connected to the two winding units 222, and each winding unit 222 is connected to a pulley 232, thereby under the drive of the first drive component 221, the two winding units 222 can simultaneously drive the two pulleys 232 to move closer or further away from each other, thereby realizing the clamping or releasing of both ends of the wall panel.

[0042] In one embodiment, such as Figure 5 and Figure 6As shown, any winding unit 222 includes a winding roller 2221, a turbine 2222, a worm gear 2223, a cable 2224, a first sprocket 2225, a second sprocket 2226, and a chain 2227. The winding roller 2221 and the turbine 2222 are spaced apart and rotatably mounted on the first housing 21. The first sprocket 2225 is mounted on the winding roller 2221, the second sprocket 2226 is mounted on the turbine 2222, and the chain 2227 is mounted on the first sprocket 2225.
