Description

Technical Field

[0001] This invention belongs to the field of prefabricated component hoisting, and particularly relates to a hoisting device for prefabricated building components. Background Technology

[0002] Prefabricated building components refer to building parts that are prefabricated in a factory and then assembled and connected on the construction site to form a complete building. This method transfers the traditional on-site construction process to a factory environment, thereby improving construction efficiency, reducing costs, minimizing environmental pollution, and enhancing building quality.

[0003] Currently, for the hoisting of building components, multiple hoisting ropes can be directly connected to the components for hoisting, or specialized hoisting equipment can be used to hoist the components.

[0004] However, while rope hoisting is simple to operate, low in cost, and highly flexible, it suffers from poor stability. Hoisting with lifting gear, on the other hand, offers improved stability, but the lifting gear itself is relatively complex, requiring a cumbersome assembly process and constant adjustments to match the corresponding building components. Furthermore, a single type of lifting gear can typically only be used to hoist a few specific types of building components, resulting in significant limitations in its application. Summary of the Invention

[0005] In view of the above problems, the present application provides a prefabricated building component hoisting equipment that can flexibly adjust the traction mechanism according to the position of the hoisting point on the building component, thereby improving the universality of hoisting while ensuring stability.

The guide post is slidably disposed in the second sliding groove, and a first screw is rotatably disposed in the second sliding groove. The first screw is threadedly connected to the guide post.

[0009] According to an advantageous embodiment, a turntable is rotatably provided at the end of the second crossbeam away from the connecting seat. The turntable is fixedly connected to the end of the first screw. Guide holes communicating with the first slide groove are provided on both longer side walls of the first crossbeam. Limit pins are slidably connected in the guide holes. The limit pins are fixedly connected to the side walls of the second crossbeam.

[0010] According to an advantageous embodiment, the second crossbeam has a rectangular moving channel extending along its length. A sliding hole is provided on the lower side of the moving channel. Two sets of symmetrically distributed first toothed plates of the same length as the moving channel are fixedly arranged on the lower inner wall of the moving channel. A slide block is slidably connected inside the moving channel. Two sets of symmetrically distributed second toothed plates are fixedly arranged on the lower side wall of the slide block. The second toothed plates engage with the lower first toothed plates. The slide block is connected to a traction mechanism.

[0011] According to an advantageous embodiment, the traction mechanism includes two mounting columns, both of which are fixedly connected to the lower side wall of the slide, and a pulley assembly is provided between the two mounting columns. A drive assembly is provided on the pulley assembly, and a connecting buckle is also provided on the pulley assembly.

[0012] According to an advantageous embodiment, the pulley block includes two pulley seats symmetrically arranged vertically. A rotating shaft is rotatably arranged on the pulley seats, and two pulley bodies are fixedly arranged on the rotating shaft. A traction rope is sleeved between the four pulley bodies. One end of the traction rope is fixedly connected to any one of the upper pulley bodies, and the traction rope is slidably sleeved on the other three pulley bodies. The other end of the traction rope is fixedly connected to the lower side wall of the upper pulley seat, and the connecting buckle is fixedly connected to the lower side wall of the lower pulley seat.

[0013] According to an advantageous embodiment, the drive assembly includes a worm gear fixedly connected to one end of an upper rotating shaft, a worm gear meshing with a worm rotatably mounted on the side wall of an upper pulley seat via a connecting plate, and a motor fixedly mounted on a mounting post near the worm gear, the output shaft of the motor being fixedly connected to one end of the worm gear.

[0014] According to an advantageous embodiment, the cable harness assembly includes four second screws rotatably disposed on the lower side wall of the lower connecting seat. The four second screws are threadedly connected to a cable harness seat. The cable harness seat has four circumferentially arranged mating grooves.

[0016] Compared with the prior art, the prefabricated building component hoisting equipment provided in this embodiment of the invention has the following beneficial effects:

[0017] 1. In this invention, the first locking component and the second locking component in the connecting mechanism cooperate with each other. The two crossbeam components on the connecting seat can rotate with the connecting seat at the same time, and can also rotate around the connecting seat to adjust the position of the traction mechanism while the connecting seat remains stationary. This allows the four traction mechanisms to match the appropriate hoisting points on the building components as much as possible for stable hoisting operations. It has good stability and good hoisting flexibility, and better adaptability.

[0018] 2. In this invention, the first crossbeam and the second crossbeam provided in the crossbeam assembly can slide relative to each other for adjustment. At the same time, the slide on the second crossbeam can drive the traction mechanism to perform secondary movement adjustment relative to the second crossbeam, which further improves the flexibility of the traction mechanism during hoisting.

[0019] 3. In this invention, the hoisting rope and the limiting rope in the cable assembly can automatically press against the outer wall of the building component when taut, thereby limiting the building component and making the building component more stable during hoisting.

[0030] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0031] Please refer to the following: Figure 1 and Figure 8A prefabricated building component hoisting device includes a connecting mechanism 1, on which four X-shaped crossbeam assemblies 2 are mounted. A traction mechanism 3 is mounted on each crossbeam assembly 2. The connecting mechanism 1 also includes a cable harness assembly 4 that cooperates with the traction mechanism 3 to limit the movement of the building component. The four crossbeam assemblies 2 are mounted in an X-shape on the connecting mechanism 1. After the traction mechanism 3 is connected to external fixing components (dedicated hooks or other clamps adapted to the building component), the external fixing components lock to the building component and guide the traction mechanism 3 through the cable harness assembly 4, enabling the four traction mechanisms 3 to cooperate in hoisting the building component.

[0032] See Figure 1 , Figure 2 , Figure 3 The connecting mechanism 1 includes two upper and lower disc-shaped connecting seats 11, which are rotatably connected by a connecting shaft 12. A first locking component 13 is provided between the two connecting seats 11. Two symmetrical arc-shaped grooves 111 are formed on the outer wall of each connecting seat 11. An arc-shaped first guide rod 14 is fixedly installed within each arc-shaped groove 111 and is connected to a corresponding crossbeam assembly 2. A second locking component 15 is provided on the connecting seat 11 to limit the position of the crossbeam assembly 2. The first locking component 13 locks the relative position of the upper and lower connecting seats 11, preventing them from rotating relative to each other, while the second locking component 15 limits the position of the crossbeam assembly 2, locking it onto the connecting seat 11.

[0033] See Figure 3The first locking assembly 13 includes a plurality of second guide rods 131, which are fixedly disposed on the lower side wall of the upper connecting seat 11 and evenly distributed along the circumference of the connecting seat 11. A locking ring 132 is slidably connected among the plurality of second guide rods 131. A plurality of first positioning pins 133 are fixedly disposed on the lower side wall edge of the locking ring 132 and evenly distributed along its circumference. A plurality of positioning grooves are opened on the upper side wall edge of the lower connecting seat 11 and evenly distributed along its circumference. The first positioning pins 133 are slidably inserted into the positioning grooves. A plurality of first springs 134 are fixedly connected between the upper side wall of the locking ring 132 and the lower side wall of the upper connecting seat 11 and evenly distributed along the circumference of the locking ring 132. The upper and lower connecting seats 11 rotate through the connecting shaft 12. The locking ring 132 moves down under the action of the first spring 134, so that the first positioning pin 133 is inserted into the positioning groove on the upper side wall surface of the lower connecting seat 11, thus locking the two together. When needed, the operator can push the locking ring 132 upward to disengage the first positioning pin 133 from the positioning groove, thereby releasing the lock on the connecting seat 11, allowing the upper connecting seat 11 to rotate and adjust its position. After adjusting to the appropriate position, the locking ring 132 is released, so that the first positioning pin 133 on the locking ring 132 can be inserted back into the corresponding positioning groove for locking.

[0034] See Figure 1 , Figure 2 , Figure 3 and Figure 4The connecting seat 11 has a cavity 112 inside that communicates with two adjacent arc-shaped grooves 111. The surface of the connecting seat 11 away from the connecting shaft 12 has a through hole that communicates with the cavity 112. The second locking assembly 15 includes a locking disc 151 that is slidably disposed in the cavity 112. A pressing post 152 is fixedly disposed on the side of the locking disc 151 near the through hole. One end of the pressing post 152 is slidably connected to the through hole. A plurality of second springs 153 are fixedly disposed on the side of the locking disc 151 away from the through hole. One end of the second spring 153 away from the locking disc 151 is fixedly connected to the inner wall of the cavity 112. A connecting plate 154 is disposed on the crossbeam assembly 2. A positioning hole is provided on the surface of the connecting plate 154. A plurality of second positioning pins 155 are disposed on the side of the locking disc 151 near the through hole, opposite each arc-shaped groove 111. The plurality of second positioning pins 155 are evenly distributed along the arc direction of the arc-shaped groove 111. The positioning hole and the second positioning pin 155 are slidably inserted into each other. The locking disc 151, through the action of the second spring 153, allows the second positioning pin 155 on the locking disc 151 to be inserted into the positioning hole on the corresponding connecting plate 154, preventing the connecting plate 154 from rotating. This also prevents the crossbeam assembly 2 connected to the connecting plate 154 from rotating independently. When the operator pushes the end of the pressing column 152, the pressing column 152 drives the locking disc 151 to slide in the cavity 112, causing the second positioning pin 155, which was originally inserted into the positioning hole, to slide and eventually separate from the positioning hole. This releases the limit on the crossbeam assembly 2, allowing the crossbeam assembly 2 to rotate around the center of the connecting seat 11, thereby allowing the position of the traction mechanism 3 on the crossbeam assembly 2 to be adjusted independently.

[0035] To facilitate adjustment of the traction mechanism 3 according to the position of the hoisting points on the building components, when the hoisting points on the building components are symmetrical, the first locking component 13 releases the restriction between the upper and lower connecting seats 11, allowing the upper and lower connecting seats 11 to rotate relative to each other, causing the two symmetrical crossbeam assemblies 2 on the connecting seats 11 to rotate together, adjusting the position of the crossbeam assembly 2 to a suitable position; when the hoisting points on the building components are asymmetrical, the second locking component 15 releases the restriction of the corresponding crossbeam assembly 2, allowing the corresponding crossbeam assembly 2 to rotate around the center of the connecting seat 11 to adjust the angle, thereby adjusting the position of the corresponding traction mechanism 3, making the hoisting point of the traction mechanism 3 more free.

[0036] See Figure 1 , Figure 2 , Figure 3 and Figure 4The crossbeam assembly 2 includes a first crossbeam 21. One end of the first crossbeam 21 near the connecting seat 11 is slidably disposed in the corresponding arc-shaped groove 111. A connecting plate 154 is fixedly connected to the end face of the first crossbeam 21 located in the arc-shaped groove 111. A first guide rod 14 is slidably connected to the corresponding first crossbeam 21. A first sliding groove is opened on the lower side of the first crossbeam 21. A guide post 22 is fixedly disposed in the first sliding groove. A second crossbeam 23 is slidably disposed in the first sliding groove. A second sliding groove is opened on the second crossbeam 23. The guide post 22 is slidably disposed in the second sliding groove. A first screw 24 is rotatably disposed in the second sliding groove. The first screw 24 is threadedly connected to the guide post 22. A turntable 25 is rotatably mounted on the end of the second crossbeam 23 furthest from the connecting seat 11. The turntable 25 is fixedly connected to the end of the first screw 24 closest to it. Guide holes communicating with the first sliding groove are provided on the longer side walls of the first crossbeam 21. Limit pins 26 are slidably connected within the guide holes and are fixedly connected to the side walls of the second crossbeam 23. The limit pins 26 can move synchronously within the guide holes when the second crossbeam 23 slides, preventing the second crossbeam 23 from completely moving off the first crossbeam 21 when it reaches its limit position. The operator controls the rotation of the turntable 25, causing the first screw 24 to rotate, thereby driving the second crossbeam 23 to slide relative to the first crossbeam 21, adjusting the position of the traction mechanism 3.

[0037] See Figure 4 and Figure 5 A rectangular moving channel 27 extending along the length of the second crossbeam 23 is provided. A sliding hole is provided on the lower side of the moving channel 27. Two sets of symmetrically distributed first toothed plates 28, equal in length to the moving channel 27, are fixedly installed on the lower inner wall of the moving channel 27. A slide block 29 is slidably connected within the moving channel 27. Two sets of symmetrically distributed second toothed plates 30 are fixedly installed on the lower side wall of the slide block 29. The second toothed plates 30 engage with the lower first toothed plates 28. The slide block 29 is connected to the traction mechanism 3. The operator uses tools to lift the slide block 29 upwards, separating the lower second toothed plates 30 from the lower first toothed plates 28. Then, the slide block 29 is moved within the moving channel 27 and adjusted to a suitable position before being lowered back down, causing the lower second toothed plates 30 to engage again with the lower first toothed plates 28 within the moving channel 27, thus limiting the movement of the slide block 29.

[0038] To further facilitate the adjustment of the traction mechanism 3 according to the position of the building component hoisting point, the traction mechanism 3 is installed on the slide 29. The slide 29 can move on the second crossbeam 23, and the second crossbeam 23 itself can also move relative to the first crossbeam 21. The traction mechanism 3 on each crossbeam assembly 2 can slide in two stages, so that the traction mechanism 3 can be adjusted more flexibly according to the position of the building component hoisting point.

[0039] See Figure 1 , Figure 4 , Figure 5 and Figure 6 The traction mechanism 3 includes two mounting posts 31, both fixedly connected to the lower side wall of the slide block 29. A pulley assembly 32 is provided between the two mounting posts 31. A drive assembly 33 is provided on the pulley assembly 32, and a connecting buckle 34 is also provided on the pulley assembly 32. The pulley assembly 32 includes two vertically symmetrical pulley seats 321. A rotating shaft 322 is rotatably mounted on the pulley seat 321. Two pulley bodies 323 are fixedly mounted on the rotating shaft 322. A traction rope 324 is sleeved between the four pulley bodies 323. One end of the traction rope 324 is fixedly connected to any one of the upper pulley bodies 323, and the traction rope 324 is slidably sleeved on the other three pulley bodies 323. The other end of the traction rope 324 is fixedly connected to the lower side wall of the upper pulley seat 321, and the connecting buckle 34 is fixedly connected to the lower side wall of the lower pulley seat 321. The drive assembly 33 includes a worm gear 331 fixedly connected to one end of the upper rotating shaft 322. A worm 332 is meshed on the worm gear 331 and rotatably mounted on the side wall of the upper pulley seat 321 via a connecting plate. A motor 333 is fixedly mounted on the mounting post 31 near the worm 332, and the output shaft of the motor 333 is fixedly connected to one end of the worm 332. The first end of the traction rope 324 is fixed to one of the upper pulley bodies, and then the traction rope 324 is sleeved on the surface of the pulley body 323 directly below it. Then the traction rope 324 is sleeved on the surface of the other upper pulley body 323, passes through the pulley body 323, and is then sleeved on the surface of the pulley body 323 below it. Finally, the end of the traction rope 324 is fixed to the lower side wall of the upper pulley seat 321. The worm gear 332, driven by motor 333, rotates, causing the worm wheel 331 to rotate the shaft 322 on the upper pulley seat 321. Since one end of the traction rope 324 is fixedly connected to one of the pulley bodies 323 on the shaft 322, the traction rope 324 winds around the pulley body 323 along with the shaft 322. Simultaneously, the other three pulley bodies 323 cooperate, causing the lower pulley seat 321 to gradually move upward, thus lifting the corresponding hoisting point. This allows for the control of tilting the building components during hoisting.

[0040] See Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 9The cable harness assembly 4 includes four second screws 41 rotatably mounted on the lower side wall of the lower connecting seat 11. A cable harness seat 42 is threadedly connected to each of the four second screws 41. The cable harness seat 42 has four circumferentially arranged mating grooves. A ring 43 is fixedly mounted on the outer side wall of the cable harness seat 42. A lifting rope 44 is slidably connected to a segment of the ring 43 within each mating groove. One end of the lifting rope 44 is fixedly connected to a corresponding connecting buckle 34. A locking buckle 45 is fitted onto the surface of the lifting rope 44. A limiting rope 46 is fixedly mounted between two adjacent locking buckles 45. A locking bolt is threaded onto the surface of the locking buckle 45, with the end of the locking bolt abutting against the surface of the lifting rope 44. The locking buckle 45 is fixed to the lifting rope 44 by the locking bolt, facilitating adjustment of the specific position of the limiting rope 46. Simultaneously, the locking buckle 45 and the limiting rope 46 can be detached from the lifting rope 44 when not needed. A first gear 47 is fixedly installed on the upper side wall of the second screw 41, and a second gear 48 is rotatably installed at the middle position of the lower side wall of the lower connecting seat 11, which meshes with all four first gears 47. Multiple push seats 49 are fixedly installed on the lower side wall of the second gear 48.

[0041] To further improve the stability of building components during hoisting, workers can push the arbitrary push seat 49 to rotate the second gear 48, which in turn rotates the four first gears 47, controlling the lower cable tie seat 42 to move up or down, adjusting the distance between the cable tie seat 42 and the corresponding building component. One end of the hoisting rope 44 is connected to a fixing piece (a special hook or special clamp) and then locked to the hoisting point at the bottom of the building component. The upper connecting seat 11 is connected to the rope on the external crane. The contraction of the rope on the crane causes the traction mechanism 3 to lift, pulling the hoisting rope 44 to tighten. The four hoisting ropes 44 are brought closer together by the cable tie seat 42, allowing the hoisting ropes 44 to be close to the surface of the building component, limiting the building component's position. At the same time, there is also a limiting rope 46 between two adjacent hoisting ropes 44, which also fits against the surface of the building component, limiting the building component's position during hoisting, further improving the stability of the building component during hoisting. When the building component is a large vertically placed pipe or a large rectangular column, such as Figure 8 As shown, after the pipe fitting is erected, the fixing parts on the lifting rope 44 are secured to the lower edge of the pipe fitting. The fixing parts on the four lifting ropes 44 are connected to the pipe fitting from different directions. When the traction mechanism 3 rises, the lifting ropes 44 are taut under traction force. At this time, the lifting ropes 44 will contact the surface of the pipe fitting, and the limiting ropes 46 between adjacent lifting ropes 44 will adhere to the surface of the pipe fitting for limiting. When the building component is a horizontally placed stone slab, such as Figure 9 As shown, the fasteners on the four hoisting ropes 44 are fixedly connected to the lower part of the stone slab from different directions. When the traction mechanism 3 rises, the hoisting ropes 44 are taut by the traction force. At this time, the four hoisting ropes 44 can contact the four side walls of the stone slab respectively, thereby limiting the position of the stone slab.

[0042] In practical operation, the four crossbeam assemblies 2 are respectively installed on the connecting mechanism 1. The two connecting seats 11 on the connecting mechanism 1 are locked together by the first locking assembly 13. When the first locking assembly 13 is unlocked, the relative positions of the four crossbeam assemblies 2 can be adjusted. The crossbeam assembly 2 itself is connected to the connecting seat 11 through the second locking assembly 15. When the second locking assembly 15 unlocks the crossbeam assembly 2, the crossbeam assembly 2 can rotate independently to adjust the position of the corresponding traction mechanism 3. At the same time, the crossbeam assembly 2 itself can extend and retract to further change the position of the traction mechanism 3, making the position adjustment of the traction mechanism 3 more flexible. After the traction mechanism 3 equipped on the crossbeam assembly 2 is connected to the external fixing component (dedicated hook or other clamps adapted to the building component), the external fixing component is locked to the building component, and the traction mechanism 3 is guided by the cable assembly 4, so that the four traction mechanisms 3 can cooperate with each other to lift the building component.
