Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically relating to an integrated device for stacking and transporting irregularly shaped PC components and its construction method. Background Technology

[0002] With social development and advancements in construction technology, prefabricated construction is increasingly advocated in the building industry, leading to a higher utilization rate of prefabricated components. However, composite slabs, a common type of precast concrete (PC) component, face challenges in stacking and transportation, including low storage space utilization, repeated lifting during transport, and susceptibility to damage. Furthermore, as a customized product, PC components often exhibit irregular shapes and specifications, resulting in space-consuming and time-consuming stacking and transportation of these irregularly shaped composite slabs, significantly impacting construction efficiency. To address these issues in existing technologies, this application proposes an integrated stacking and transportation device and its construction method for irregularly shaped PC components. This device and method will resolve the problems associated with stacking and transporting irregularly shaped composite slabs. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0004] An integrated stacking and transporting device for irregularly shaped PC components is characterized by: a carrying plate 1 located at the bottom, several supporting mechanisms on the front and rear sides of the carrying plate 1, several clamping mechanisms on the left and right sides of the carrying plate 1, the carrying plate 1 comprising two plates, left and right, and an unfolding device at the bottom of the carrying plate 1, the unfolding device comprising a scissor-type telescopic frame 2 and an elliptical ring track 25, the elliptical ring track 25 being divided into two halves respectively opened at the bottom of the left and right plates of the carrying plate, the end of the scissor-type telescopic frame 2 being provided with a slider 24, the slider 24 being embedded in the elliptical ring track 25, and when the scissor-type telescopic frame 2 is extended and retracted, the slider 24 slides within the elliptical ring track 25 to adjust the distance between the left and right plates of the carrying plate.

[0005] The scissor-type telescopic frame 2 includes two hollow square steel pipes 22 that are hinged together in the middle. Each of the four ends of the square steel pipe 22 is fitted with a telescopic pipe 23 with an outer diameter slightly smaller than that of the square steel pipe. The telescopic pipe 23 adjusts the telescopic range of the scissor-type telescopic frame 2 by telescopically moving within the square steel pipe 22.

[0006] Each of the four ends of the two square steel tubes 22 is provided with a fixing bolt 26. The telescopic tube 23 has a row of bolt holes on the side corresponding to the fixing bolt 26 on the square steel tube 22. The telescopic tube 23 is moved to the required length and fixed by the fixing bolt 26 and the bolt holes. The slider 24 is set at the end of the telescopic tube 23. The slider 24 is a T-shaped block structure. The elliptical ring track 25 is an inner concave groove that is adapted to the shape of the T-shaped slider.

[0007] The support mechanism includes a sleeve 4 disposed on the front and rear sides of the carrying plate 1. A toothed rod 8 is fitted inside the bottom of the sleeve 4. The toothed rod 8 can slide up and down inside the sleeve. The lower end of the toothed rod 8 is connected to a gas-liquid damper 9 for shock absorption during the movement of the device. The lower end of the gas-liquid damper 9 is connected to a roller 10 with a brake pad 34. The roller 10 is a universal wheel and can rotate freely.

[0008] Eight sleeves 4 are symmetrically arranged on the front and rear sides of the carrying plate 1, and a toothed rod 8 is fitted inside the bottom of each sleeve 4.

[0009] Several sets of gears are symmetrically arranged on the front and rear sides of the carrying plate 1. Each set of gears meshes with a set of wheels. The set of wheels includes an operating part gear disk group 7 that meshes with one side of the gear 8. The gear disk group 7 includes a spur gear disk 28, a helical gear disk 27, and a turntable 29. The spur gear disk 28, the helical gear disk 27, and the turntable 29 are coaxially connected to the same connecting rod 17. Another spur gear disk is provided at the other end of the connecting rod 17. The teeth of the spur gear disk 28 mesh with the teeth of the gear 8. A second one-way clamp 16b is provided above the helical gear disk 27. The end of the second one-way clamp 16b is hinged and fixed to the sleeve 4. The second one-way clamp 16b can rotate around the axis fixed to the sleeve 4. A handle 15 is provided above the second one-way clamp 16b. The handle 15 is connected to the sleeve 4 through the support rod 3. The support rod 3 is vertically fixed above the second one-way clamp 16b on the outside of the sleeve 4. The handle 15 can rotate around the axis fixed on the support rod 3. A rotary spring is provided inside the handle 15. One end of the spring is placed on the support rod 3 and the other end is placed inside the handle 15. The spring applies a counterclockwise rotational force to the handle 15, which is transmitted to the second one-way clamp 16b through the front end of the handle 15, causing it to rotate clockwise and generate a downward force acting on the helical gear plate 27, ensuring that the second one-way clamp 16b and the helical gear plate 27 are always tightly fitted.

[0010] The connecting rod 17 connects a spur gear 28, a helical gear 27, and a turntable 29 on the operating side, and only a spur gear 28 is provided on the non-operating side. The four spur gears on the non-operating side are respectively connected to four racks 8 located on that side. Two gears connected by the same connecting rod 17 form a set of wheels. The device has four sets of wheels, namely the first set of wheels 18, the second set of wheels 19, the third set of wheels 20, and the fourth set of wheels 21. When the turntable 29 is rotated clockwise, it drives the helical gear plate 27 and the spur gear plate 28 to rotate clockwise. The spur gear plate 28 drives the rack 8 to lift upwards. The connecting rod 17 drives the spur gear plate 28 on the opposite side to rotate, which in turn drives the rack 8 on the opposite side to lift upwards, thus achieving synchronous lifting of the same set of wheels. When the rotation stops, the carrying plate 1 will move downwards due to gravity, causing the spur gear plate 28 to rotate counterclockwise, which in turn drives the helical gear plate 27 to rotate counterclockwise. Due to the presence of the second one-way clamp 16b, the counterclockwise rotation of the helical gear plate 27 can be prevented, thus preventing the downward movement of the entire set of wheels, achieving the purpose of self-locking.

[0011] The clamping mechanism includes several sets of fixing components arranged on the left and right sides above the carrier plate 1. Each set of fixing components can be advanced a different distance according to the shape of the component to perfectly fit the irregular component and achieve the purpose of fastening the irregular component. The fixing components include a hollow outer tube 11 that can move left and right. The upper end of the hollow outer tube 11 is provided with a fin tooth groove 32. The hollow outer tube 11 is provided with a threaded inner tube 14. Fin teeth 31 are fixed above the inner end of the threaded inner tube 14. Fin teeth 31 move along the fin tooth groove 32. The tail end of the hollow outer tube 11 is provided with a rotating nut 13. The rotating nut 13 is provided with a rotating rod 12. The rotating rod 12 can be operated to rotate the rotating nut 13. The threaded inner tube 14 matches the rotating nut 13. A first one-way clamp 16a is provided on the upper part of the hollow outer tube 11 and the threaded inner tube 14. The end of the first one-way clamp 16a abuts against the outside of the fin teeth 31.

[0012] Each of the sleeves 4 has several symmetrical semi-circular support blocks 5 on its left and right sides, and a fixing ring 6 on the top outer side for fixing the entire frame to the transport vehicle. The semi-circular support blocks 5 are fixed to the sleeves 4 by bolts, and the bolts are screwed inwards at a distance less than the distance from the toothed rod 8 to the inner wall of the sleeve 4.

[0013] Each of the sleeves 4 is provided with eight sets of support blocks 5 at equal intervals along the longitudinal direction of the sleeve, which are used to place the single-layer load plate located on the upper layer in sequence. The support blocks 5 are detachable.

[0014] The single-layer loading plate located on the upper layer has a collar 33 on its side corresponding to the sleeve 4. The inner diameter of the collar 33 is slightly larger than the outer diameter of the sleeve 4. After the single-layer loading plate is sleeved on the sleeve 4 through the collar 33, it is placed on the support block 5 of each layer for support and fixation. The bottom of the single-layer loading plate located on the upper layer is also provided with an unfolding device.

[0015] A construction method for an integrated stacking and transport device for irregularly shaped PC components, characterized by comprising the following steps:

[0016] First, adjust the unfolding distance of the carrying plate 1, fix the fixing bolts 26 to ensure that the scissor telescopic frame 2 no longer moves, lower the brake pads 34 to ensure that the entire device no longer moves, hoist the component onto the carrying plate 1, move each hollow outer tube 11 towards the component until it touches the component, rotate the rotating nut 13 to move the threaded inner tube 14 away from the component until the fin teeth 31 touch the first one-way clamp 16a, then stop rotating the rotating nut 13 and install the bottom support block 5; then install the upper single-layer carrying plate 1, place the component on it, push the hollow outer tube, and rotate the rotating nut 13 again until the fin teeth 31 touch the first one-way clamp 16a to complete the loading of the second layer carrying plate, and then install the second layer support block 5; proceed in sequence until all the upper carrying plates are loaded, open the brake pads 34, push the device to the stacking area, and after reaching the stacking area, lower the brake pads to complete the stacking;

[0017] When transportation is required, the brake pads are released to push the device toward the transport vehicle. Assuming the fourth set of wheels 21 is close to the vehicle, the turntable 29 is rotated to raise the fourth set of wheels 21 until the roller 10 is exactly at the height of the vehicle's loading platform. The device is then pushed forward until the third set of wheels 20 is close to the vehicle's loading platform. At this point, the fourth set of wheels 21 is supported on the vehicle's loading platform. The turntable 29 is rotated to raise the third set of wheels 20 until the roller 10 is exactly at the height of the vehicle's loading platform. The device is then pushed forward until the second set of wheels 19 and the first set of wheels 18 are all on the vehicle's loading platform. The component is then pushed to the designated position, the brake pads are released, and the entire frame is secured to the vehicle's loading platform by passing a rope through the fixing ring 6 at the top of the sleeve 4. At this point, the entire component is loaded onto the vehicle.

[0018] When unloading, untie the fixing ropes, open the brake pads, pull the frame until the first set of wheels 18 is suspended in the air, press the second one-way clamp 16b to lower the rack 8 down to the roller 10 and touch the ground, continue pulling forward until the third set of wheels 20 is suspended in the air, press the second one-way clamp 16b to lower the rack 8 down to the roller 10 and touch the ground, continue pulling forward until the third set of wheels 20 and the fourth set of wheels 21 are lowered to the ground in sequence, completing the unloading of the entire component.

[0019] The present invention has the following advantages:

[0020] 1. This invention provides an efficient and feasible construction method for stacking and transporting irregularly shaped PC components.

[0021] 2. The invention device adopts a scissor telescopic structure combined with an elliptical ring track, so that the device can be unfolded. It can unfold to different sizes according to different components, adapting to the stacking and transportation of more specifications of PC components, thus improving the applicability of the device.

[0022] 3. The invention device adopts a design with four sets of independently operating wheels, which solves the problem of the stacking rack being unable to move. In addition, the independent lifting design solves the problem of the inconvenience of loading and unloading the rack and the need for a crane, which greatly improves the efficiency of loading and unloading and saves manpower and material resources.

[0023] 4. The invention device achieves the purpose of fastening irregularly shaped components by designing multiple sets of independent spiral inner tubes and hollow outer tubes, thus solving the problem of displacement of irregularly shaped components during movement or transportation.

[0024] 5. The invention device achieves shock absorption by setting up a gas-liquid damper, reducing the problem of components being damaged by disturbance during movement or transportation.

[0025] 6. The invention device achieves the purpose of stacking multiple layers of a single frame by setting up support blocks and single-layer load-bearing plates, thus solving the problem of damage caused by stacking components. Attached Figure Description

Detailed Implementation

[0036] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings, such as... Figure 1-9As shown, an integrated stacking and transport device for irregularly shaped PC components includes a loading plate 1 located at the bottom. The loading plate 1 has several supporting mechanisms on its front and rear sides, and several clamping mechanisms on its left and right sides. The loading plate 1 comprises two plates, left and right. An unfolding device is located at the bottom of the loading plate 1. The unfolding device includes a scissor-type telescopic frame 2 and an elliptical ring track 25. The elliptical ring track 25 is divided into two halves, each located at the bottom of the left and right plates of the loading plate. A slider 24 is provided at the end of the scissor-type telescopic frame 2. The slider 24 is embedded within the elliptical ring track 25. When the scissor-type telescopic frame 2 extends and retracts, the slider 24 slides within the elliptical ring track 25, adjusting the distance between the left and right plates of the loading plate.

[0037] The scissor-type telescopic frame 2 includes two hollow square steel tubes 22 that are hinged together in the middle. Each of the four ends of the square steel tube 22 is fitted with a telescopic tube 23 with an outer diameter slightly smaller than that of the square steel tube. The telescopic tube 23 adjusts the telescopic range of the scissor-type telescopic frame 2 by telescopically moving within the square steel tube 22.

[0038] Each of the four ends of the two square steel tubes 22 is provided with a fixing bolt 26. The telescopic tube 23 has a row of bolt holes on the side corresponding to the fixing bolt 26 on the square steel tube 22. The telescopic tube 23 is moved to the required length and fixed by the fixing bolt 26 and the bolt holes. The slider 24 is set at the end of the telescopic tube 23. The slider 24 is a T-shaped block structure. The elliptical ring track 25 is an inner concave groove that is adapted to the shape of the T-shaped slider.

[0039] The support mechanism includes a sleeve 4 set on the front and rear sides of the carrying plate 1. A toothed rod 8 is fitted inside the bottom of the sleeve 4. The toothed rod 8 can slide up and down inside the sleeve. The lower end of the toothed rod 8 is connected to a gas-liquid damper 9 for shock absorption during the movement of the device. The lower end of the gas-liquid damper 9 is connected to a roller 10 with a brake pad 34. The roller 10 is a universal wheel and can rotate freely.

[0040] Eight sleeves 4 are symmetrically arranged on the front and rear sides of the carrying plate 1, and a toothed rod 8 is fitted inside the bottom of each sleeve 4. Several sets of toothed rods are symmetrically arranged on the front and rear sides of the carrying plate 1. Each set of toothed rods cooperates with a set of wheels. The set of wheels includes an operating part gear disk group 7 that engages with the toothed rod 8 on one side. The gear disk group 7 includes a spur gear disk 28, a helical gear disk 27, and a turntable 29. The spur gear disk 28, the helical gear disk 27, and the turntable 29 are coaxially connected to the same connecting rod 17. Another spur gear disk is provided at the other end of the connecting rod 17. The teeth of the spur gear disk 28 engage with the teeth of the toothed rod 8. A second one-way clamp 16b is provided above the helical gear disk 27. The end of the second one-way clamp 16b is hinged and fixed to the sleeve 4. The second one-way clamp 16b can rotate around the axis fixed to the sleeve 4. A handle 15 is provided above the second one-way clamp 16b. The handle 15 is connected to the sleeve 4 through the support rod 3. The support rod 3 is vertically fixed above the second one-way clamp 16b on the outside of the sleeve 4. The handle 15 can rotate around the axis fixed on the support rod 3. A rotary spring is provided inside the handle 15. One end of the spring is placed on the support rod 3 and the other end is placed inside the handle 15. The spring applies a counterclockwise rotational force to the handle 15, which is transmitted to the second one-way clamp 16b through the front end of the handle 15, causing it to rotate clockwise and generate a downward force acting on the helical gear plate 27, ensuring that the second one-way clamp 16b and the helical gear plate 27 are always tightly fitted.

[0041] Linkage 17 connects to a spur gear 28, a helical gear 27, and a turntable 29 on the operating side, and only a spur gear 28 on the non-operating side. The four spur gears on the non-operating side are respectively connected to four racks 8 located on that side. Two gears connected by the same link 17 form a set of wheels. The device has four sets of wheels, namely the first set of wheels 18, the second set of wheels 19, the third set of wheels 20, and the fourth set of wheels 21. When the turntable 29 is rotated clockwise, it drives the helical gear plate 27 and the spur gear plate 28 to rotate clockwise. The spur gear plate 28 drives the rack 8 to lift upwards. The connecting rod 17 drives the spur gear plate 28 on the opposite side to rotate, which in turn drives the rack 8 on the opposite side to lift upwards, thus achieving synchronous lifting of the same set of wheels. When the rotation stops, the carrying plate 1 will move downwards due to gravity, causing the spur gear plate 28 to rotate counterclockwise, which in turn drives the helical gear plate 27 to rotate counterclockwise. Due to the presence of the second one-way clamp 16b, the counterclockwise rotation of the helical gear plate 27 can be prevented, thus preventing the downward movement of the entire set of wheels, achieving the purpose of self-locking.

[0042] The clamping mechanism includes several sets of fixing components arranged on the left and right sides above the carrying plate 1. Each set of fixing components can be advanced a different distance according to the shape of the component to perfectly fit the irregular component and achieve the purpose of fastening the irregular component. The fixing components include a hollow outer tube 11 that can move left and right. The upper end of the hollow outer tube 11 is provided with a fin tooth groove 32. The inside of the hollow outer tube 11 is provided with a threaded inner tube 14. Fin teeth 31 are fixed above the inner end of the threaded inner tube 14. Fin teeth 31 move along the fin tooth groove 32. The tail end of the hollow outer tube 11 is provided with a rotating nut 13. The rotating nut 13 is provided with a rotating rod 12. The rotating rod 12 can be operated to rotate the rotating nut 13. The threaded inner tube 14 matches the rotating nut 13. A first one-way clamp 16a is provided on the upper part of the hollow outer tube 11 and the threaded inner tube 14. The end of the first one-way clamp 16a abuts against the outside of the fin teeth 31.

[0043] Each of the sleeves 4 has several symmetrical semi-circular support blocks 5 on its left and right sides, and a fixing ring 6 on the top outer side for fixing the entire frame to the transport vehicle. The semi-circular support blocks 5 are fixed to the sleeves 4 by bolts, and the bolts are screwed inwards at a distance less than the distance from the toothed rod 8 to the inner wall of the sleeve 4.

[0044] Each sleeve 4 has eight sets of support blocks 5 at equal intervals along the longitudinal direction of the sleeve, which are used to place the single-layer load plate located on the upper layer in sequence. The support blocks 5 are detachable.

[0045] The upper single-layer loading plate has a collar 33 on its side corresponding to the sleeve 4. The inner diameter of the collar 33 is slightly larger than the outer diameter of the sleeve 4. After the single-layer loading plate is fitted onto the sleeve 4 through the collar 33, it is placed on the support block 5 of each layer for support and fixation. The bottom of the upper single-layer loading plate is also provided with an unfolding device.

[0046] A construction method for an integrated stacking and transportation device for irregularly shaped PC components includes the following steps:

[0047] First, adjust the unfolding distance of the carrying plate 1, fix the fixing bolts 26 to ensure that the scissor telescopic frame 2 no longer moves, lower the brake pads 34 to ensure that the entire device no longer moves, hoist the component onto the carrying plate 1, move each hollow outer tube 11 towards the component until it touches the component, rotate the rotating nut 13 to move the threaded inner tube 14 away from the component until the fin teeth 31 touch the first one-way clamp 16a, then stop rotating the rotating nut 13 and install the bottom support block 5; then install the upper single-layer carrying plate 1, place the component on it, push the hollow outer tube, and rotate the rotating nut 13 again until the fin teeth 31 touch the first one-way clamp 16a to complete the loading of the second layer carrying plate, and then install the second layer support block 5; proceed in sequence until all the upper carrying plates are loaded, open the brake pads 34, push the device to the stacking area, and after reaching the stacking area, lower the brake pads to complete the stacking;

[0048] When transportation is required, the brake pads are released to push the device toward the transport vehicle. Assuming the fourth set of wheels 21 is close to the vehicle, the turntable 29 is rotated to raise the fourth set of wheels 21 until the roller 10 is exactly at the height of the vehicle's loading platform. The device is then pushed forward until the third set of wheels 20 is close to the vehicle's loading platform. At this point, the fourth set of wheels 21 is supported on the vehicle's loading platform. The turntable 29 is rotated to raise the third set of wheels 20 until the roller 10 is exactly at the height of the vehicle's loading platform. The device is then pushed forward until the second set of wheels 19 and the first set of wheels 18 are all on the vehicle's loading platform. The component is then pushed to the designated position, the brake pads are released, and the entire frame is secured to the vehicle's loading platform by passing a rope through the fixing ring 6 at the top of the sleeve 4. At this point, the entire component is loaded onto the vehicle.

[0049] When unloading, untie the fixing ropes, open the brake pads, pull the frame until the first set of wheels 18 is suspended in the air, press the second one-way clamp 16b to lower the rack 8 down to the roller 10 and touch the ground, continue pulling forward until the third set of wheels 20 is suspended in the air, press the second one-way clamp 16b to lower the rack 8 down to the roller 10 and touch the ground, continue pulling forward until the third set of wheels 20 and the fourth set of wheels 21 are lowered to the ground in sequence, completing the unloading of the entire component.

[0050] The scope of protection of this invention is not limited to the embodiments described above. Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its scope and spirit. If these modifications and variations fall within the scope of the claims of this invention and their equivalents, then the intent of this invention also includes these modifications and variations.
