Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building construction technology, specifically a hoisting device for prefabricated buildings. Background Technology

[0002] Prefabricated construction refers to transferring a large amount of on-site work from traditional construction methods to factories. Building components and accessories, such as floor slabs, wall panels, stairs, and balconies, are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. Prefabricated buildings mainly include precast concrete structures, steel structures, and modern wood structures. Because they adopt standardized design, factory production, assembly construction, information management, and intelligent applications, they represent modern industrialized production methods. Hoisting equipment is required to lift the prefabricated panels on the construction site of prefabricated buildings.

[0003] Existing hoisting equipment is too bulky, inconvenient to store when not in use, and not flexible enough when in use. It is also unstable during hoisting, unable to stabilize the position of the components, and prone to falling off, resulting in a low safety factor.

[0004] Therefore, this utility model provides a hoisting device for prefabricated buildings. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A hoisting device for prefabricated buildings, comprising a support base; a servo motor is fixedly connected to the bottom of the support base, a straight shaft is fixedly connected to the top of the servo motor, the straight shaft is rotatably connected to the support base, multiple cables are fixedly connected to the outside of the straight shaft, multiple through holes are opened on the outside of the support base, the cables are slidably connected to the through holes, a hoisting block is fixedly connected to the end of the through hole, a slot is opened on one side of the hoisting block, a rope is fixedly connected to the top of the hoisting block, and a hook is fixedly connected to one end of the rope. During operation, the servo motor is first started, driving the straight shaft to rotate, thereby rotating the cables out. The ends of the multiple cables are connected to the straight shaft. In the same direction, the forward and reverse rotation of the linear shaft can control the release distance of the cable. Adjust the cable distance according to the size of the assembly plate, then align the lifting clamp with the corner of the assembly plate, insert the clamp into the corner, and ensure the support base fits against the bottom of the assembly plate. Then, start the servo motor to retract the cable tightly, ensuring a close fit between the lifting clamp and the assembly plate. Next, attach the hook to the crane, and the hook pulls the rope, which in turn pulls multiple clamps to transport the assembly plate. After use, remove the lifting clamp and start the servo motor to rewind the cable. By setting a support base to support the center of the assembly plate and adjusting the cable with the servo motor, it is easy to adapt to different sized assembly plates, achieving quick adjustment and flexible, convenient use.

[0007] Preferably, the top of the slot is provided with a screw rod, which is threadedly connected to the lifting block. A clamping plate is fixedly connected to the bottom of the screw rod, and a handle is fixedly connected to the top of the screw rod. During operation, when the assembly plate is placed in the slot, the handle is rotated, and the screw rod moves up and down on the lifting block, thereby adjusting the position of the clamping plate in the slot. The clamping plate provides auxiliary fixation for the assembly plate and can be adjusted according to the size of the assembly plate to reduce the phenomenon of the assembly plate shaking in the slot. By setting the screw rod, clamping plate, and handle, assembly plates of different sizes can be tightly fitted with the slot, reducing gaps between the assembly plate and the slot, and further improving the stability of the assembly plate during the lifting process.

[0008] Preferably, two sleeves are fixedly connected to the other side of the lifting block. A spring is fixedly connected to the middle of the sleeve, and a sleeve rod is fixedly connected to one end of the spring. The sleeve rod is slidably connected to the sleeve, and an elastic ball is fixedly connected to one end of the sleeve rod. During operation, the elastic ball is provided on the outside of the lifting block. When the lifting block collides with the outside, the elastic ball will first contact the object to buffer it. Then the sleeve rod will squeeze the spring. After the spring is compressed, the sleeve rod slides in the sleeve. Then the spring force reacts to the sleeve rod, pushing the sleeve rod and the elastic ball to return to their original positions, reducing the possibility of the lifting block hitting the object, and thus reducing the phenomenon of damage to the assembly plate due to collision.

[0009] Preferably, airbags are provided on both sides of the sleeve. The airbags are fixedly connected to the lifting block. During operation, the airbags extend to the outer range of the lifting block, thereby increasing the distance between the airbags and the assembly plate. When the lifting block comes into contact with an object, the airbags will block it, further reducing the occurrence of collisions with the assembly plate during this process.

[0010] Preferably, the top of the support base is provided with a silicone pad, which is fixedly connected to the support base. During operation, the silicone pad increases the friction between the assembly plate and the support base, reducing the sliding of the assembly plate on the support base.

[0011] Preferably, a protective ring is fixedly connected to the outside of the through hole. The protective ring is slidably connected to the cable. During operation, the cable passes through the through hole, and friction between the cable and the through hole is inevitable. The protective ring protects the cable, reduces the phenomenon of cable damage caused by the through hole, and extends the service life.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The hoisting device for prefabricated buildings described in this utility model supports the center of the assembly plate by setting a support base, and the servo motor adjusts the cable, which is convenient to adapt to the use of assembly plates of different sizes, and achieves the effect of quick adjustment and flexible and convenient use.

[0014] 2. The hoisting device for prefabricated buildings described in this utility model, by setting screws, clamps, and handles, enables assembly plates of different sizes to fit tightly with the slots, reduces gaps between the assembly plates and the slots, and further improves the stability of the assembly plates during hoisting.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 3 As shown in the embodiment of this utility model, a hoisting device for prefabricated buildings includes a support base 1. A servo motor 11 is fixedly connected to the bottom of the support base 1, and a straight shaft 12 is fixedly connected to the top of the servo motor 11. The straight shaft 12 is rotatably connected to the support base 1. Multiple cables 13 are fixedly connected to the outside of the straight shaft 12. Multiple through holes 14 are opened on the outside of the support base 1. The cables 13 are slidably connected to the through holes 14. A hoisting block 15 is fixedly connected to the end of the through hole 14. A slot 16 is opened on one side of the hoisting block 15. A rope 17 is fixedly connected to the top of the hoisting block 15. A hook 18 is fixedly connected to one end of the rope 17. During operation, the servo motor 11 is first started, which drives the straight shaft 12 to rotate, thereby rotating the cables 13. The ends of the multiple cables 13 are connected to different sides of the straight shaft 12. The forward and reverse rotation of the linear shaft 12 controls the release distance of the cable 13. Adjust the cable 13 to an appropriate distance according to the size of the assembly plate. Then, align the lifting block 15 with the corner of the assembly plate, insert the slot 16 into the corner, and ensure the support base 1 fits against the bottom of the assembly plate. Start the servo motor 11 to retract the cable 13 tightly, ensuring a close fit between the lifting block 15 and the assembly plate. Next, hang the hook 18 on the crane, which pulls the rope 17, which in turn pulls multiple slots 16 to transport the assembly plate. After use, remove the lifting block 15 and start the servo motor 11 to rewind the cable 13. By setting the support base 1 to support the center of the assembly plate and adjusting the cable 13 with the servo motor 11, it is easy to adapt to assembly plates of different sizes, achieving rapid adjustment and flexible, convenient use.

[0024] like Figures 1 to 4As shown, a screw 2 is provided at the top of the slot 16. The screw 2 is threadedly connected to the lifting block 15. A clamping plate 21 is fixedly connected to the bottom of the screw 2, and a handle 22 is fixedly connected to the top of the screw 2. During operation, when the assembly plate is placed in the slot 16, the handle 22 is rotated, and the screw 2 moves up and down on the lifting block 15, thereby adjusting the position of the clamping plate 21 in the slot 16. The clamping plate 21 provides auxiliary fixation for the assembly plate and can be adjusted according to the size of the assembly plate to reduce the phenomenon of the assembly plate shaking in the slot 16. By setting the screw 2, clamping plate 21, and handle 22, assembly plates of different sizes can be tightly fitted with the slot 16, reducing gaps between them and the slot 16, and further improving the stability of the assembly plate during the lifting process.

[0025] like Figures 1 to 5 As shown, two sleeves 3 are fixedly connected to the other side of the lifting block 15. A spring 31 is fixedly connected to the middle of the sleeve 3. A sleeve rod 32 is fixedly connected to one end of the spring 31. The sleeve rod 32 is slidably connected to the sleeve 3. An elastic ball 33 is fixedly connected to one end of the sleeve rod 32. During operation, the elastic ball 33 is provided on the outside of the lifting block 15. When the lifting block 15 collides with the outside, the elastic ball 33 will first contact the object to buffer it. Then the sleeve rod 32 will squeeze the spring 31. After the spring 31 is compressed, the sleeve rod 32 slides in the sleeve 3. Then the elastic force of the spring 31 reacts to the sleeve rod 32, pushing the sleeve rod 32 and the elastic ball 33 to return to their original positions, reducing the possibility of the lifting block 15 hitting the object, and thus reducing the phenomenon of damage to the assembly plate due to collision.

[0026] like Figures 1 to 4 As shown, airbags 4 are provided on both sides of the sleeve 3. The airbags 4 are fixedly connected to the lifting block 15. During operation, the airbags 4 extend to the outer range of the lifting block 15, thereby increasing the distance with the assembly plate. When the lifting block 15 comes into contact with an object, the airbags 4 will block it, further reducing the occurrence of the assembly plate being collided during this process.

[0027] like Figure 3 As shown, a silicone pad 5 is provided on the top of the support base 1. The silicone pad 5 is fixedly connected to the support base 1. During operation, the silicone pad 5 increases the friction between the assembly plate and the support base 1, reducing the sliding of the assembly plate on the support base 1.

[0028] like Figures 2 to 3 As shown, a protective ring 6 is fixedly connected to the outside of the through hole 14. The protective ring 6 is slidably connected to the cable 13. During operation, the cable 13 passes through the through hole 14. Friction between the cable 13 and the through hole 14 is inevitable. The protective ring 6 protects the cable 13, reduces the phenomenon of cable 13 being damaged by the through hole 14, and extends its service life.

[0029] Working principle: First, start the servo motor 11, which drives the linear shaft 12 to rotate, thereby rotating out the cable 13. The ends of multiple cables 13 are connected to different directions of the linear shaft 12. The forward and reverse rotation of the linear shaft 12 can control the release distance of the cable 13. According to the size of the assembly plate, adjust the cable 13 to an appropriate distance. Then, align the lifting block 15 with the corner of the assembly plate, and insert the slot 16 into the corner of the assembly plate. The support base 1 fits against the bottom of the assembly plate. Then, start the servo motor 11 to retract and tighten the cable 13, so that the lifting block 15 fits tightly with the assembly plate. Finally, hang the hook 18 on the crane, and the hook 18 pulls the rope 1. 7. Rope 17 pulls multiple slots 16 to transport the assembly plate. After use, the lifting block 15 is removed, and the servo motor 11 is started to reel in the cable 13. The assembly plate is supported at its center by a support base 1, and the servo motor 11 adjusts the cable 13 to accommodate assembly plates of different sizes, achieving quick adjustment and flexible use. When the assembly plate is placed in the slot 16, the handle 22 is turned, and the screw 2 rises and falls on the lifting block 15, thereby adjusting the position of the clamp 21 in the slot 16. The clamp 21 provides auxiliary fixation for the assembly plate and can be adjusted according to the size of the assembly plate. To minimize the wobbling of the assembly plate within the slot 16, the screw 2, clamp 21, and handle 22 are designed to ensure a tight fit between assembly plates of different sizes and the slot 16, reducing gaps and further improving the stability of the assembly plate during hoisting. The hoisting block 15 has an elastic ball 33 on its outer side. When the hoisting block 15 collides with an external object, the elastic ball 33 will first contact the object for cushioning. Subsequently, the sleeve rod 32 will compress the spring 31. After the spring 31 is compressed, the sleeve rod 32 slides within the sleeve 3. Then, the spring force of the spring 31 reacts to the sleeve rod 32, pushing the sleeve rod 32 and the elastic ball 33 back to their original positions, reducing the impact of the hoisting process. The mounting block 15 is designed to reduce the possibility of impact with objects, thereby reducing the possibility of damage to the assembly plate due to collision. The airbag 4 extends to the outer range of the mounting block 15, thereby increasing the distance between it and the assembly plate. When the mounting block 15 comes into contact with an object, the airbag 4 will block it, further reducing the possibility of the assembly plate being hit during this process. The silicone pad 5 increases the friction between the assembly plate and the support base 1, reducing the possibility of the assembly plate sliding on the support base 1. The cable 13 passes through the through hole 14. Friction between the cable 13 and the through hole 14 is inevitable. The protective ring 6 protects the cable 13, reducing the possibility of the cable 13 being damaged by the through hole 14 and extending its service life.
