Description

Technical Field

[0001] The invention relates to a transfer device for transferring a prefabricated building component from one position to another, belonging to the field of prefabricated buildings. Background Art

[0002] Prefabricated buildings are buildings that are manufactured by moving traditional on-site cast parts to the factory, and then transporting them to the construction site for on-site assembly. The components of prefabricated buildings are produced in factories, so they can be standardized in design and industrialized in production. This not only allows for good quality control, but also speeds up the construction cycle of buildings. They are the representative of modern production. Building components that are standardized in factories are generally cast on a formwork table. First, the mold is assembled on the surface of the formwork table, and then the concrete material is poured into the mold by the distribution device. After smoothing and vibration compaction, the formwork table and the components are put into the curing kiln for curing. After the curing is completed, the concrete components have hardened. At this time, the components need to be removed from the formwork table and transported out of the factory building, and then stacked in the factory area to wait for transportation. Since concrete components are very heavy, the transportation process is very laborious. Currently, workers use trolleys to transport them. They need to stand the components up and put them in the bucket of the trolley. One person pushes the trolley, and several people hold the components for transportation. In this process, it is very difficult to stand the components up, and equipment such as cranes are needed to assist. In addition, because the workshop is noisy, the lifting process may also injure workers doing other operations. When the components are transported to the factory, it is even more difficult to unload them from the trolley, because there is no lifting equipment outside like in the workshop, and they need to be carried manually, which is very difficult. When the components are transported away, they need to be lifted onto the truck, which is even more difficult. Summary of the invention

[0003] The purpose of the present invention is to provide a prefabricated building component transfer device to solve the problem of difficulty in transferring prefabricated building components in the prior art.

[0004] In order to achieve the above objectives, the present invention adopts the following technical scheme: an assembled building component transfer device, comprising a lifting mechanism, the lifting mechanism having a lifting part that moves vertically for lifting components on both sides, a moving frame is provided on the upper sliding guide of the frame, a hook is provided on the moving frame, the lower end of the hook has a hook portion for hooking components on both sides, each hook portion is below the extreme position after the lifting part moves up, a moving structure is provided between the hook and the moving frame to enable the hook portion on one side to open and close with the hook portion on the other side to allow components to pass through or hook the components, and a positioning structure is provided between the hook and the moving frame to position the hook after each hook portion hooks the component.

[0005] The motion structure includes a rotating part that rotatably assembles the upper end of each hook with the moving frame, a driving part that pushes the upper end of each hook to close the hook on one side and the hook on the other side, and a resetting part that drives the upper end of each hook to open the hook on one side and the hook on the other side.

[0006] The driving part comprises a crank slider mechanism assembled on the moving frame, and the slider of the crank slider mechanism is pushed and matched with the upper end of each hook.

[0007] The positioning structure is a crank slider mechanism corresponding to each hook, and after each hook hooks the component, the crank and connecting rod of the crank slider mechanism are in line.

[0008] The rotating part comprises a pair of assembly ears fixed on the hook, a fixed ear protruding from the corresponding position of the movable frame and extending between the pair of assembly ears, and a pin shaft for rotating and assembling the assembly ear and the fixed ear together.

[0009] The reset part is a reset torsion spring arranged between the moving frame and the hook.

[0010] A descending mechanism having the same structure as the lifting mechanism is also arranged on one side of the lifting mechanism.

[0011] The lifting mechanism includes a frame, on which are arranged two pairs of chain transmission mechanisms, with two sprockets of each chain transmission mechanism arranged one above and one below, and the two chain transmission mechanisms of a pair of chain transmission mechanisms are respectively located on both sides, and the lifting part is a support plate rotatably arranged on the chain of each chain transmission mechanism and moving vertically with the chain, and a supporting support plate is fixed on the chain so that the support plate can lift the component.

[0012] The movable frame is moved and guided by two parallel guide rails, and the lower part of the movable frame is provided with rollers which cooperate with the two guide rails.

[0013] The two ends of the guide rail are detachably fixed on the frame of the lifting mechanism and the frame of the descending mechanism.

[0014] The present invention has a lifting mechanism, the lifting part of the lifting mechanism will lift the component, and at the same time, the hooks on both sides will be opened. Because the hooks are below the limit position after the lifting part moves up, the component can be moved onto the hook part of the hook, and then the hooks on both sides are retracted, and then the lifting part of the lifting mechanism is lowered, the component will be separated from the lifting part and hooked by the hook, and the moving frame can be moved to transport the component. No manual lifting is required, making the transfer of the component simple and easy.

[0015] One side of the lifting mechanism of the present invention is also provided with a landing mechanism with the same structure as the lifting mechanism. When the component moves to the landing mechanism along with the mobile frame, the lifting part of the landing mechanism moves up to support the component, the hooks on both sides open, and the lifting part of the landing mechanism descends to put down the component. A supporting protrusion is provided on the foundation, and the component can be placed on the supporting protrusion to complete the transfer.

[0016] The landing mechanism and the lifting mechanism of the present invention have the same structure, and the main body is a chain transmission mechanism. The lifting part is a support plate that is rotatably arranged on the chain of each chain transmission mechanism and moves vertically with the chain. A fixed support that supports the support plate so that the support plate can lift the component is fixed on the chain. In this way, when the landing mechanism is working, after the component is put down, the support plate continues to move down. When encountering an obstacle, it will rotate to pass the obstacle and turn to the other side of the chain transmission mechanism and then turn back to the working side to continue to receive the component. It is only necessary to place a support between adjacent components so that the two adjacent components do not touch each other tightly, and the components can be stacked up without putting down a component and changing a position. The landing mechanism can also be directly set on both sides of the truck, and the component device can be transported on the truck. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Embodiment 1 of a prefabricated building component transfer device, in Figure 1-8 In the invention, there is a lifting mechanism 1 and a lowering mechanism 2, and the structures of the lifting mechanism 1 and the lowering mechanism 2 are exactly the same. Here, the lifting mechanism 1 is taken as an example to describe its structure. The frame 3 of the lifting mechanism 1 is divided into two parts, and the two parts are respectively located on both sides. The two parts are respectively fixed on the ground foundation. The opposite side of the two parts is the inner side, and the other side is the outer side. Two sets of chain transmission mechanisms 4 are arranged on both parts of the frame 3, and a chain transmission mechanism on one part is a pair with a chain transmission mechanism on the other part, and the positions of the pair of chain transmission mechanisms correspond. The two sprocket wheels 5 of each chain transmission mechanism 4 are arranged one above and one below, that is, the chain transmission mechanism 4 is arranged vertically. A support plate 6 is rotatably mounted on the chain of each chain transmission mechanism 4, and a fixed support 7 is also fixedly arranged on the chain. When the support plate 6 is on the inner side, the fixed support 7 will lift the support plate so that the support plate 6 cannot hang down. At this time, the four support plates 6 can lift the components upward after moving upward.

[0028] Two mutually parallel guide rails 8 are arranged above the lifting mechanism 1 and the lowering mechanism 2. The two ends of the guide rails 8 are supported on the frame of the lifting mechanism 1 and the frame of the lowering mechanism 2 respectively. The fixing between the guide rails and the frame of the lifting mechanism 1 is detachable, and the fixing between the guide rails and the frame of the lowering mechanism 2 is also detachable. In this embodiment, bolts are used for fixing. A crossbeam 9 is arranged between the two parts of the frame of the lifting mechanism 1. The two ends of the crossbeam 9 are respectively fixed to the two parts of the frame of the lifting mechanism 1 by bolts. Similarly, a crossbeam is also arranged between the two parts of the frame of the lowering mechanism 2. The two ends of this crossbeam are also respectively fixed to the two parts of the frame of the lowering mechanism 2 by bolts. The two ends of the guide rails are respectively fixed to the two crossbeams. In this way, the guide rails and the frame of the lifting mechanism and the frame of the lowering mechanism are all detachable, which is convenient for storage and easy to move, and can be conveniently transported to the required place.

[0029] A movable frame 10 is provided on the two guide rails 8. The movable frame 10 is plate-shaped, and rollers 11 are provided on the lower surface thereof for rotation. There are four rollers 11, two of which are in rolling cooperation with one guide rail, and the other two are in rolling cooperation with the other guide rail. The two rollers 11 respectively cooperating with the two guide rails share a rotating shaft 12, and the other two rollers also share a rotating shaft. One of the rotating shafts 12 is rotatably provided on the movable frame 10 through two bearing seats, and the corresponding two rollers 11 are fixedly assembled on the two ends of the rotating shaft 12. The rotating shaft 12 is driven by a movable motor 13, and the movable motor 13 drives the rotating shaft 12 to rotate after passing through a reduction mechanism. The reduction mechanism has two bevel gears meshing with each other, one of which is fixedly provided on the rotating shaft 12, and the other is installed on the output shaft of the movable motor. Driving the movable motor 13 to rotate can drive the rollers to rotate, so that the movable frame moves relative to the guide rail. The movable motor 13 is fixed on the movable frame through a support frame 14. The movable motor 13 is a motor with a stop locking function.

[0030] Two hooks 15 are provided on one side of the mobile frame 10, and two hooks 15 are also provided on the other side of the mobile frame 10. The upper end of the hook 15 is rotatably assembled on the mobile frame 10, and the lower end of the hook 15 has a hook portion 16. The rotational assembly between the hook 15 and the mobile frame 10 is achieved as follows: the hook 15 is provided with assembly ears 24 arranged in pairs, and a fixed ear 17 is convexly provided on the corresponding side of the mobile frame. The fixed ear 17 extends between the corresponding pair of assembly ears 24, and the fixed ear and the assembly ear are rotationally assembled together through the pin 18, thereby realizing the rotational assembly between the hook 15 and the mobile frame. A reset torsion spring is respectively provided on each pin 18, and the reset torsion spring can open the hooks on both sides. The setting method of the reset torsion spring is conventional technology. Two mutually meshing gears 19 are rotatably arranged on the upper surface of the moving frame 10, and connecting rods 20 are rotatably arranged on the wheel surfaces of the two gears 19, and the two connecting rods 20 correspond to a slider 21, respectively. One gear 19 and the corresponding connecting rod 20 and slider 21 form a crank slider mechanism, and the slider 21 slides and presses on the upper ends of a pair of hooks, so that the pair of hooks overcome the spring force of the reset torsion spring and close, and one of the two gears 19 is driven to rotate by the rotating motor 22. Another pair of crank slider mechanisms with the same structure as the above-mentioned crank slider mechanism are also arranged on the moving frame corresponding to the other pair of hooks.

[0031] When the slider moves to the outer limit position, the corresponding hook is closed, and the corresponding connecting rod is in line with the crank at this time, that is, it is the dead point position, and even if the slider is driven by the hook, the slider will not move and is in a positioned state. The rotating motor 22 is a motor with a stop locking function.

[0032] The transfer device in this embodiment has multiple use occasions. When removing the component from the mold platform, it needs to be used in conjunction with the split mold platform. The two sides of the mold platform can be lowered. In this way, the middle part of the component is supported on the middle part of the mold platform, and the two sides of the component are suspended. The lifting mechanism is placed on both sides of the mold platform, and the drive chain transmission mechanism moves so that the support plate moves to the bottom of the component to lift the component. The crank of the crank slider mechanism moves inward, and the hook opens under the action of the reset torsion spring, so that the component can pass through, and then the crank slider mechanism is driven to move. The slider overcomes the spring force of the reset torsion spring, so that the hook is retracted. At this time, the drive chain transmission mechanism moves, so that the support plate moves down together with the component, and the component will be hung by the hook. The moving motor is driven to move the moving frame to transfer the component. The mold platforms can all be removed from each mold platform by passing between the two parts of the frame of the lifting device.

[0033] When stacking components, use the landing mechanism. When the mobile frame moves to the landing mechanism, let the pallet move up, hold the component and move up a little, so that the component completely leaves the hook. After the hook is opened, the pallet moves down with the component. After placing the component on the support, the pallet continues to move down. When encountering an obstacle, the pallet will rotate to pass the obstacle, turn to the other side of the chain drive mechanism, and then turn back to the working side to continue receiving the component.

[0034] When transferring the stacked components, the pallet of the lifting mechanism is rotated to the top of the component stack, and then the pallet is moved down. When it touches the top component, the pallet rotates to make way for the component. When the pallet moves between two components, the pallet is supported on the fixed support under the action of gravity. Then the pallet is moved up to lift the top component and send the component to the hook. Then the pallet continues to move down, repeating the above action to lift the second component. The method of rotating the pallet to the top of the component stack can be to keep moving the pallet down to the sprocket below and turn to the other side, and then turn back to the inside.

[0035] When loading the components, the lowering mechanism is set on both sides of the truck. Since the sides of the truck can be opened, the components can be stacked on the truck by stacking the components, and a spacer can be set between two adjacent components. Figure 1 The crossbeam of the landing mechanism is not shown because the crossbeam is on the outside of the pallet. Figure 1 It is a cross-sectional view with the beam cut off.

[0036] Embodiment 2 of a prefabricated building component transfer device, Fig. 9 and Fig.10 The difference between this embodiment and embodiment 1 is that no landing mechanism is provided, the other end of the guide rail is fixed on the bracket 23, and the fixing method of the guide rail and the bracket 23 is also detachable.

[0037] The lifting mechanism in the above-mentioned embodiment is a chain transmission mechanism, and in other embodiments it may also be a hydraulic cylinder assembly capable of lifting the component.

[0038] The hook in the above embodiment is rotatably mounted on the mobile frame, and in other embodiments it may be horizontally mounted on the mobile frame. In this structure, its opening and closing can be achieved by using a hydraulic cylinder.

[0039] The movable frame in the above-mentioned embodiment is arranged to be moved by means of guide rails, and can also be guided and moved by means of structures such as guide rods.

[0040] When the descending mechanism is not provided, the component is lowered manually.
