Description

Technical Field

[0001] This invention relates to the field of building construction machine technology, specifically a prefabricated component lifting and conveying system for prefabricated buildings. Background Technology

[0002] The top of the building construction machine is mainly a frame, which facilitates movement for people. A curtain is installed in the space between the frames. During construction, the main work area is located below the building construction machine platform. When the curtain is closed, it avoids direct sunlight and facilitates subsequent curing of building materials.

[0003] Firstly, prefabricated buildings are often transported in the form of prefabricated components. The number of building construction machines increases with the building's height, leading to a corresponding increase in the travel and cycle time of subsequent hoisting operations. For small prefabricated components, cargo elevators can be used for transport. However, for large prefabricated components, hoisting is the only option, followed by placement through the gaps in the platform above the building construction machine into the assembly area below.

[0004] The fixing method of the traction rope is not stable. In actual operation, the traction rope is responsible for bearing the weight of the precast component, and multiple auxiliary traction mechanisms fix multiple points of the precast component for positioning or auxiliary traction, so that the precast component is lowered accurately. Due to the limited travel area of ​​the frame above the building machine and the limited number of load-bearing points above the building machine, the efficiency of the auxiliary traction above is low. Therefore, how to accurately and quickly send the precast component through the opening at the top of the building machine into the construction area below is a problem that needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a prefabricated component lifting and conveying system for prefabricated buildings, which can solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A precast component lifting and conveying system for prefabricated buildings includes a building machine. A precast component platform lifter is mounted on the side of the building machine for lifting precast components onto an operating platform. A self-propelled precast component alignment platform is slidably connected to the precast component platform lifter for actively aligning with the lifted precast components. A precast component positioning conveyor is mounted on the top of the building machine for positioning and conveying the precast components lifted onto the operating platform. The precast component positioning conveyor has at least two movement tracks, and each track is slidably connected to a precast component longitudinal guide release device. The precast component longitudinal guide release device is used to move and convey the precast components lifted by the self-propelled precast component alignment platform onto the operating platform.

[0007] As a further embodiment of the present invention: the precast component positioning conveyor consists of a transverse conveying track and a longitudinal conveying track, which are vertically intersecting. The transverse conveying track and the longitudinal conveying track move along the two horizontal and vertical sides of the operating platform, respectively. Both ends of the transverse conveying track and the longitudinal conveying track are open structures. When the precast component longitudinal guide release device moves to the edge limit position of the transverse conveying track or the longitudinal conveying track, the precast component longitudinal guide release device is located directly above the self-propelled precast component alignment platform.

[0008] As a further embodiment of the present invention: the precast component positioning conveyor consists of a long-distance fixed track and a short-distance sliding track, with a gap between the long-distance fixed track and the short-distance sliding track. The long-distance fixed track is fixedly connected to the line connecting the midpoints of the short sides of the operating platform. The two ends of the short-distance sliding track are slidably connected to the long sides of the operating platform, and the short-distance sliding track is located below the long-distance fixed track. The precast component platform lifter and the self-propelled precast component alignment platform are respectively arranged on the side of the building machine near the end of the long-distance fixed track, and the self-propelled precast component alignment platform corresponds to the end of the long-distance fixed track. Two precast component longitudinal guide release devices are slidably connected on the long-distance fixed track, and at least one precast component longitudinal guide release device is slidably connected on the short-distance sliding track.

[0009] As a further embodiment of the present invention: the precast platform lifter includes a vertical lifting track, a vertical sliding mechanism, a rotating locking plate, and a sliding platform. The vertical lifting track and the sliding platform are fixedly connected to the side of the building machine. The vertical sliding mechanism is slidably connected to the vertical lifting track, and the rotating locking plate is rotatably connected to the side of the vertical sliding mechanism.

[0010] As a further embodiment of the present invention: at least four columns are fixedly connected to the top of the self-propelled precast component alignment platform, and each column is provided with a conveying clamp for connecting precast components. The bottom of the self-propelled precast component alignment platform is provided with a self-propelled mechanism for driving the self-propelled precast component alignment platform to move. A limiting disk is fixedly connected to the outer wall of the self-propelled mechanism. The limiting disk is circular. The surface of the sliding platform is provided with a sliding trajectory groove for the movement of the self-propelled mechanism. The side wall of the sliding trajectory groove is provided with a limiting groove that cooperates with the limiting disk.

[0011] As a further embodiment of the present invention: the rotating locking plate is detachably connected to the self-propelled prefabricated component alignment platform, an insert-type fixing device is provided on the inner side of the rotating locking plate, a hole is opened on the side of the self-propelled prefabricated component alignment platform, a trigger controller is provided in the hole to cooperate with the insert-type fixing device, and four sets of retractable corners are provided on the surface of the sliding platform, the telescopic mechanism of the retractable corners is signal connected to the trigger controller.

[0012] As a further embodiment of the present invention: a surrounding storage compartment is vertically slidably connected inside the prefabricated longitudinal guide release device. The inner side wall of the surrounding storage compartment has several equidistantly distributed plate-type limiting grooves. Several clamping units are vertically and equidistantly fixedly connected inside the plate-type limiting grooves. A protruding connecting unit is fixedly connected to the outer wall of the surrounding storage compartment. The prefabricated longitudinal guide release device and the protruding connecting unit are slidably connected through a multi-section telescopic sleeve rod.

[0013] As a further embodiment of the present invention: the top of the building machine is fixedly connected to a support rail, the support rail supports the track of the precast component positioning conveyor, and there is a margin of space between the precast component positioning conveyor and the operating platform to meet the construction requirements.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This system distributes hoisting and positioning across two areas, enabling the positioning and transport of prefabricated components on the building construction machine platform. While effectively utilizing the space of the machine, the different areas allow for overlapping hoisting and positioning operations, facilitating better monitoring and management of the entire construction process. The system employs a multi-stage process: alignment and locking of the self-propelled prefabricated component alignment platform with the prefabricated component; locking the platform with the longitudinal guide release device using a platform lifter; adjusting the horizontal position of the longitudinal guide release device using a prefabricated component positioning conveyor; and finally, directional vertical release using the longitudinal guide release device. This method solves the problem of limited open space above the building construction machine and difficulty in hoisting components to the installation area. Furthermore, it can be easily modified and added to existing building construction machines, demonstrating significant application value. Attached Figure Description

[0017] Please see Figures 1-7 : The system includes a building machine 1, on the side of which is a precast component platform lifter 4 for lifting precast components onto the operating platform. A self-propelled precast component alignment platform 5 is slidably connected to the precast component platform lifter 4 for actively aligning with the precast components. A precast component positioning conveyor 2 is installed on the top of the building machine 1 for positioning and conveying the precast components lifted onto the operating platform. The precast component positioning conveyor 2 has at least two motion tracks, and each precast component positioning conveyor 2 is slidably connected to a precast component longitudinal guide release device 3. The precast component longitudinal guide release device 3 is used to move and convey the precast components lifted by the self-propelled precast component alignment platform 5 on the operating platform. Firstly, since long-distance rail transport of large precast components is impractical due to numerous safety considerations, a follow-up short-distance sidewall lifting method is proposed to address these issues. This method separates hoisting and positioning into two steps, which is more conducive to construction process management.

[0018] Firstly, the building machine 1 will increase in height as the number of floors in the building increases. Therefore, a precast platform lifter 4 is installed on the side of the building machine 1. Although the precast platform lifter 4 is a bracket with a low load-bearing capacity, it only exists in a local area. Therefore, the strength of the bracket can be increased locally.

[0019] The precast platform lifter 4 needs to provide temporary support for the precast components, therefore it needs to have a sliding platform 44. Simultaneously, the precast platform lifter 4 needs to raise the height, therefore it needs a vertical lifting track 41. However, the stability of the hoisting direction control is poor. To improve the fixing speed, a self-propelled precast component alignment platform 5 is installed.

[0020] Firstly, the self-propelled precast component alignment platform 5 can move on the sliding platform 44. At this point, the crane only needs to move the precast component completely to the sliding platform 44. The self-propelled precast component alignment platform 5 can then quickly move to directly below the corresponding position of the precast component using laser positioning or image algorithms. When the traction mechanism 32 releases downwards, it does not exhibit inertia as in horizontal movement. Therefore, using the self-propelled precast component alignment platform 5 to locate the precast component increases the fixing efficiency.

[0021] After the precast component is fixed in place by the self-propelled precast component alignment platform 5, it moves to the vertical lifting track 41 and is lifted to the top via the vertical lifting track 41. Since the movement of the self-propelled precast component alignment platform 5 is mainly in the form of a mechanical structure, the displacement caused by inertia is relatively low compared to the rope. Therefore, the self-propelled precast component alignment platform 5 can accurately return to the position of the vertical lifting track 41.

[0022] At this point, the prefabricated component is clamped by the prefabricated component longitudinal guide release device 3 on the prefabricated component positioning conveyor 2. Once the prefabricated component longitudinal guide release device 3 moves to the boundary of the prefabricated component positioning conveyor 2, the self-propelled prefabricated component alignment platform 5 is located directly below the prefabricated component longitudinal guide release device 3. The prefabricated component is conveyed by the rising of the self-propelled prefabricated component alignment platform 5 and the falling of the prefabricated component longitudinal guide release device 3. The self-propelled prefabricated component alignment platform 5 forms an internal fixed structure through the column 51, and the prefabricated component longitudinal guide release device 3 forms an external fixed structure through the enclosed storage compartment 31. During separation, after the enclosed storage compartment 31 is fixed to the prefabricated component, the column 51 separates from the prefabricated component. At this time, the self-propelled prefabricated component alignment platform 5 falls, and the prefabricated component longitudinal guide release device 3 can then drive the prefabricated component to move.

[0023] The precast component positioning conveyor 2 consists of a transverse conveying track 2A and a longitudinal conveying track 2B. The transverse conveying track 2A and the longitudinal conveying track 2B are vertically staggered. The transverse conveying track 2A and the longitudinal conveying track 2B move along the two horizontal and vertical sides of the operating platform, respectively. Both ends of the transverse conveying track 2A and the longitudinal conveying track 2B are open structures. When the precast component longitudinal guide release device 3 moves to the edge limit position of the transverse conveying track 2A or the longitudinal conveying track 2B, the precast component longitudinal guide release device 3 is located directly above the self-propelled precast component alignment platform 5. Example 1

[0024] The number of precast component platform lifters 4 is at least two, and each lifter 4 corresponds to a transverse conveying track 2A and a longitudinal conveying track 2B, respectively. When applied to small, square-shaped buildings, the transverse and longitudinal conveying tracks 2A and 2B are relatively short. Both transverse and longitudinal conveying tracks 2A and 2B can slide along the edge of the top platform of the building construction machine 1, and corresponding sliding tracks can be set for guidance, cooperating with traction or self-propelled mechanisms to achieve movement. Since precast component assembly has a certain cycle, the two self-propelled precast component alignment platforms 5 can synchronously transport precast components to the transverse and longitudinal conveying tracks 2A and 2B, respectively. At this time, the transverse and longitudinal conveying tracks 2A and 2B can operate synchronously at different positions. While operating simultaneously, the crane can continue to prepare the next precast component at the precast component platform lifter 4. This cross-operation method is more in line with future construction management and monitoring.

[0025] Example 2

[0026] The longitudinal conveyor track 2B is located below the transverse conveyor track 2A. The longitudinal conveyor track 2B is supported by a sliding connection with the support rail 11. There is a gap between the longitudinal conveyor track 2B and the upper operating platform of the building machine 1, which can be used for personnel movement and other operations. Simultaneously, the longitudinal conveyor track 2B supports the transverse conveyor track 2A. The top surface of the longitudinal conveyor track 2B and the bottom surface of the transverse conveyor track 2A slide relative to each other, preventing interference between the transverse conveyor track 2A and the longitudinal conveyor track 2B while increasing stability.

[0027] The precast component positioning conveyor 2 consists of a long fixed track 2C and a short sliding track 2D. There is a gap between the long fixed track 2C and the short sliding track 2D. The long fixed track 2C is fixedly connected to the line connecting the midpoints of the short sides of the operating platform. The two ends of the short sliding track 2D are slidably connected to the long sides of the operating platform. The short sliding track 2D is located below the long fixed track 2C. The precast component platform lifter 4 and the self-propelled precast component alignment platform 5 are respectively set on the side of the building machine 1 near the end of the long fixed track 2C, and the self-propelled precast component alignment platform 5 corresponds to the end of the long fixed track 2C. Example 3

[0028] Buildings with rectangular cross-sections are frequently used in residential communities, making improvements to this design potentially more widely applicable. However, when operating a building with a rectangular cross-section using this method, the long fixed track 2C between the short sides has an excessively narrow movement range and is also too long. Therefore, the long fixed track 2C is fixedly connected to the top surface of the building construction machine 1, and a precast component longitudinal guide release device 3 is slidably connected to it. The short sliding track 2D, spanning the long side, is shorter and more stable. Therefore, a precast component platform lifter 4 is placed at the end of the long fixed track 2C, allowing the long fixed track 2C to position the precast component at the centerline and lower it vertically to the work area for assembly. Simultaneously, it can divert the precast component longitudinal guide release device 3 on the short sliding track 2D, transporting the precast component from the long fixed track 2C to the short sliding track 2D.

[0029] Because there is a gap between the long-distance fixed track 2C and the short-distance sliding track 2D, the precast component longitudinal guide release device 3 on the long-distance fixed track 2C only needs to be fixed at the top of the precast component. At this time, the precast component longitudinal guide release device 3 on the short-distance sliding track 2D can move to the bottom of the precast component longitudinal guide release device 3 on the long-distance fixed track 2C. By lowering the precast component longitudinal guide release device 3 on the long-distance fixed track 2C, the unfixed area below the precast component can be transported to the precast component longitudinal guide release device 3 on the short-distance sliding track 2D. At this time, the precast component longitudinal guide release device 3 on the short-distance sliding track 2D drives the precast component to descend, thus completing the separation of the two precast component longitudinal guide release devices 3.

[0030] The precast component platform lifter 4 includes a vertical lifting track 41, a vertical sliding mechanism 42, a rotating locking plate 43, and a sliding platform 44. The vertical lifting track 41 and the sliding platform 44 are fixedly connected to the side of the building machine 1. The vertical sliding mechanism 42 is slidably connected to the vertical lifting track 41. The rotating locking plate 43 is rotatably connected to the side of the vertical sliding mechanism 42. At least four columns 51 are fixedly connected to the top of the self-propelled precast component alignment platform 5. Each column 51 is equipped with a conveying clamp 52 for connecting precast components. The bottom of the self-propelled precast component alignment platform 5 is equipped with a self-propelled mechanism 53 for driving the self-propelled precast component alignment platform 5 to move. The outer wall of the self-propelled mechanism 53 is fixedly connected to... A limiting disk 54 is connected, which is circular. The surface of the sliding platform 44 is provided with a sliding track groove 441 for the movement of the self-propelled mechanism 53. The side wall of the sliding track groove 441 is provided with a limiting groove 442 that cooperates with the limiting disk 54. The rotating locking plate 43 is detachably connected to the self-propelled prefabricated component alignment platform 5. An insert-type fixing device 431 is provided on the inner side of the rotating locking plate 43. A hole is provided on the side of the self-propelled prefabricated component alignment platform 5. A trigger controller 55 that cooperates with the insert-type fixing device 431 to trigger is provided in the hole. The surface of the sliding platform 44 is provided with four sets of retractable corners 443. The telescopic mechanism of the retractable corners 443 is connected to the trigger controller 55. Example 4

[0031] First, after the sliding platform 44, the vertical lifting track 41, and the building construction machine 1 are fixed, the self-propelled precast component alignment platform 5 slides on the sliding platform 44. However, the self-propelled precast component alignment platform 5 needs to be connected with the vertical sliding mechanism 42. Because the vertical lifting track 41 and the vertical sliding mechanism 42 form a sliding structure, but the vertical sliding mechanism 42 is long and narrow, there are few fixing points between the vertical sliding mechanism 42 and the self-propelled precast component alignment platform 5. After the rotating locking plate 43 is set, the rotating locking plate 43 can rotate to the horizontal, thereby contacting the side of the self-propelled precast component alignment platform 5, and locking is achieved by inserting the insert-type fixing device 431 into the hole. To ensure the stability of the self-propelled precast component alignment platform 5, multiple horizontally and vertically distributed grid-shaped sliding track grooves 441 are opened on the surface of the precast component platform lifter 4. The self-propelled mechanism 53 moves within the sliding track grooves 441 to achieve self-propelled movement. However, to prevent the rotating locking plate 43 from disengaging from the sliding track grooves 441, a limiting plate 54 cooperates with the limiting grooves 442. At this time, the self-propelled mechanism 53 is always in close contact with the sliding platform 44 during the movement.

[0032] However, this prevents the self-propelled precast component alignment platform 5 from separating from the precast component platform lifter 4, so a retractable corner 443 is provided. When the self-propelled precast component alignment platform 5 moves to the fixed position that engages with the rotating locking plate 43, the insert-type retainer 431 contacts the trigger controller 55 inside the hole, controlling the movement of the retractable corner 443, so that the upper end of the limiting groove 442 at the retractable corner 443 is in the open stage. At this time, the self-propelled precast component alignment platform 5 and the rotating locking plate 43 are in the locked stage, and the lifting stage can then begin.

[0033] Example 5

[0034] The main reason for setting up the columns 51 is that, for the panel, the four columns 51 form two fixed surfaces, which can also be used to fix the panel. For the frame structure, the columns 51 are located inside the structure, and can also be limited using the conveyor clamp 52. The conveyor clamp 52 can use push rods or pin holes for clamping, which will not be elaborated further here. The conveyor clamp 52 can extend into the interior of the enclosed storage compartment 31, thereby adjusting the clamping position of the prefabricated component by adjusting the enclosed storage compartment 31 according to requirements.

[0035] The prefabricated longitudinal guide release device 3 is vertically slidably connected to an enclosed storage compartment 31. The inner side wall of the enclosed storage compartment 31 has several equidistantly distributed plate-type limiting grooves 311. Several clamping units 312 are vertically and equidistantly fixedly connected within the plate-type limiting grooves 311. The outer wall of the enclosed storage compartment 31 is fixedly connected to a protruding connecting unit 313. The prefabricated longitudinal guide release device 3 and the protruding connecting unit 313 are slidably connected through a multi-section telescopic sleeve rod 33. The top of the prefabricated longitudinal guide release device 3 is rotatably connected to a guide roller 34. The outside of the prefabricated longitudinal guide release device 3 is fixedly connected to a support plate 321. The traction mechanism 32 is fixedly connected to the top of the support plate 321. The traction rope wound on the traction mechanism 32 is fixedly connected to the enclosed storage compartment 31 through the guide roller 34. First, the prefabricated component longitudinal guide release device 3 slides within the track of the prefabricated component positioning conveyor 2 via the support plate 321 and its own sidewall slider. The power source can be any form, such as traction or self-propelled. The traction mechanism 32 is mounted on the support plate 321 and is fixedly connected to the enclosed storage compartment 31 via a traction rope. Multiple plate-type limiting grooves 311 within the enclosed storage compartment 31 can cooperate to fix the plate. At the same time, the plate-type limiting grooves 311 still have rectangular space inside, so a three-dimensional rectangular frame can be stored and fixed by the clamping unit 312. Since the prefabricated component will have many pre-reserved fixing parts, the clamping unit 312 can be directly fixed to the fixing parts. Since there are many fixing methods for the clamping unit 312, and they are very common in this field, and the electric control methods are also diverse, they will not be described in detail here. When the enclosed storage compartment 31 descends, it can be guided by the protruding connecting unit 313 in cooperation with the multi-section telescopic sleeve rod 33. The guide roller 34 prevents wear on the traction rope.

[0036] The top of the building construction machine 1 is fixedly connected to a support rail 11, which supports the track of the precast component positioning conveyor 2. There is sufficient space between the precast component positioning conveyor 2 and the operating platform to meet the construction requirements. Since operators need to walk above and observe and control the precast component longitudinal guide release device 3, there is sufficient margin between the precast component positioning conveyor 2 and the operating platform to meet construction requirements.

[0037] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
