[0030] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figure 1-3 A prefabricated hoisting device for building construction is shown, comprising a lifting bracket 1, a No. 2 hydraulic rod 3 is installed on the top of the lifting bracket 1 through a shaft, a No. 1 hydraulic rod 2 is installed on the surface of the lifting bracket 1 through a shaft, and the power end of the No. 1 hydraulic rod 2 is movably connected to the surface of the No. 2 hydraulic rod 3 through a hinge, and a plurality of hook ropes 4 are connected to the power end of the No. 2 hydraulic rod 3 through a hook, a supporting plate 6 for placing building materials is arranged below the No. 2 hydraulic rod 3, and the tail end of each hook rope 4 is fixedly connected to the side surface of the supporting plate 6, and a transfer supporting plate 12 is rotatably connected to one side of the supporting plate 6 through a shaft, and a plurality of rotating parts 13 are installed on the surface of the transfer supporting plate 12, and a driving motor 7 is connected to one end of the shaft;

[0033] A side plate 61 is installed on the front of the supporting plate 6, and a plurality of binding ropes 5 are fixedly connected to the back of the supporting plate 6. A winding piece 11 corresponding in number to the binding ropes 5 is installed on the bottom of the side plate 61. The winding piece 11 includes a winding column 111 with a rotating screw installed on the surface, and a rotating gear 9 located above the side plate 61 is fixedly sleeved on the top of the rotating screw surface. A rack 10 meshing with the rotating gear 9 is slidably installed on the surface of the side plate 61, and an electric extension rod 8 is installed on the surface of the driving motor 7, and the power end of the electric extension rod 8 is connected to the end of the rack 10.

[0034] Specifically, Figure 6As shown, before lifting and hoisting, the building material object is placed on the surface of the supporting plate 6 (the middle part of the supporting plate 6 is provided with a rolling ball, which is not drawn in the figure, so that the building material object on the surface of the supporting plate 6 can be easily transferred to the surface of the transfer plate 12 when the length of the building material object is less than that of the supporting plate 6). Then, the binding rope 5 is covered on the surface of the building material object, and the excess part of the binding rope 5 is rolled up and knotted on the surface of the winding column 111, so that the binding rope 5 covering the surface of the building material object is tightly pressed on the surface of the building material object to form a bundling effect. At this time, the transfer plate 12 is also in an overlapping state with the supporting plate 6. Afterwards, with the cooperation of the No. 1 hydraulic rod 2 and the No. 2 hydraulic rod 3, the position of the supporting plate 6 is adjusted so that the supporting plate 6 reaches the specified floor position of the building (that is, the opening position for receiving the building material object). Assuming that it is necessary to To deliver building materials to the third floor, the supporting plate 6 needs to be hoisted to a position close to the ceiling of the third floor in the building (this is to provide enough space for the transfer pallet 12 to be turned over), and then the driving motor 7 is started to drive the transfer pallet 12 to turn 180 degrees to form a horizontal state (and at this time, two-thirds of the length of the transfer pallet 12 in the horizontal state is located in the building). At this time, the position of the supporting plate 6 is slightly adjusted so that the supporting plate 6 gradually drops to the position of the floor of the third floor, so that the transfer pallet 12 also gradually approaches the floor of the third floor. After that, the workers in the building can press down the end of the transfer pallet 12 located in the building, so that the supporting plate 6 and the transfer pallet 12 are in an inclined state, which is convenient for the subsequent rolling of building materials;

[0035] Figure 4-5 As shown, after the transfer tray 12 tilts and falls into the building, the electric extension rod 8 is started, driving the rack 10 to move, indirectly driving the rotating gear 9 to rotate, so that the winding column 111 rotates, and then a part of the binding rope 5 in the surface winding state is released (the winding of the surface of the winding column 111 is layer by layer, and the winding thickness is only one layer. The direction of rotation of the winding column 111 is opposite to the winding direction of the binding rope 5, so the binding rope 5 that was originally rolled up can be released, such as Figure 4 As shown in the figure), the binding rope 5 is released from the state of being tightly pressed on the surface of the building material object, so that the building material object can slide along the surface of the supporting plate 6 and the transfer supporting plate 12 into the interior space of the building under the action of its own weight.

[0036] During the above operation, when the building materials are transferred to the interior space of the building, it can avoid the safety hazards caused by workers stretching out the outside of the building to pull the building materials, and can also ensure the smooth transfer of the objects by automatically loosening the surface binding ropes 5 when the building materials are transferred, and realize the automatic loosening of the surface binding ropes 5 after the objects are transferred.

[0037] Brackets are installed at the four corners of the bottom of the supporting plate 6 , and the height of the brackets is greater than the thickness of the transfer bracket 12 , and the distance between the two brackets is greater than the width of the transfer bracket 12 .

[0038] Specifically, the brackets are installed so that when the supporting plate 6 and the adapter pallet 12 are overlapped, there is still a gap between the bottom of the adapter pallet 12 and the ground, thereby ensuring that the supporting plate 6 and the adapter pallet 12 remain stable when overlapped and will not slip due to the rotating part 13 at the bottom. In addition, the design of the spacing between the brackets can prevent the adapter pallet 12 from being disturbed by the brackets when it is flipped.

[0039] A roller is installed at the bottom of one end of the transfer plate 12 away from the driving motor 7 , and in the initial state, the transfer plate 12 and the supporting plate 6 are placed overlapping.

[0040] Specifically, the provision of the rollers facilitates the subsequent transfer tray 12 to leave the floor surface of the building with less effort.

[0041] Figure 7 As shown, a plurality of elastic ropes are installed on the surface of the hook rope 4, and the tail ends of the elastic ropes are connected to the surface of the tying rope 5.

[0042] Specifically, the installation of the elastic rope makes the binding rope 5 in a stretched state when it is pressed against the surface of the building material object. When the binding rope 5 is subsequently relaxed (that is, the winding column 111 rotates to release part of the binding rope 5), the binding rope 5 is pulled up a short distance with the help of the elastic force, so that the binding rope 5 and the elastic rope installation position are separated from the surface of the building material object, and are also synchronously lifted near the binding rope 5 and the elastic rope installation position (the lifting distance is less than the lifting distance at the binding rope 5 and the elastic rope installation position), so that the building material object is better separated from the surface of the binding rope 5.

[0043] Figure 8 As shown, the inner wall of the adapter tray 12 is provided with a recessed rectangular groove, the inner wall of the rectangular groove is installed with a micro electric telescopic rod 14, and the end of the rotating member 13 is installed with a cross plate slidably connected to the rectangular groove through an axis, the bottom of the cross plate is connected to the power end of the micro electric telescopic rod 14, and a pressure sensor is installed inside the rotating member 13.

[0044] Specifically, since the building material object may be very heavy and has rolling friction with the rotating part 13, the inertia effect is relatively large when sliding down, which may cause collision and damage to certain ornaments in the building. Therefore, a micro-electric telescopic rod 14 is designed. After the building material object leaves the surface of the rotating part 13 by two-thirds of the distance (the two-thirds distance can be adjusted according to actual conditions and is not a fixed value. It is only necessary to let the distance that the building material object falls on the surface of the floor of the building floor exceed half of the distance of the building material object itself. In this way, the center of gravity of the building material object basically falls on the floor of the building floor and will not fall in mid-air), at this time, the pressure sensors on the surfaces of several rotating parts 13 on the surface of the transfer tray 12 close to the drive motor 7 are not pressed by the building material object, so the micro-electric telescopic rod 14 retracts, causing the rotating part 13 to fall into the transfer tray 12. At this time, the friction of the building material object is switched to sliding friction, and deceleration is performed.

[0045] It also includes a lifting control system, which includes a lifting adjustment module, a transfer placement module, a release module and a control module, wherein the lifting adjustment module is signal-connected to the No. 1 hydraulic rod 2 and the No. 2 hydraulic rod 3 for controlling the lifting position of the supporting plate 6, the transfer placement module is signal-connected to the drive motor 7 and the lifting adjustment module for assisting the transfer plate 12 in horizontally overlapping and transferring building materials on the surface of the supporting plate 6, the release module is signal-connected to the electric extension rod 8 for adjusting the tightness of the binding rope 5, and the control module is signal-connected to the micro electric telescopic rod 14 for controlling the rotation state of the rotating part 13.

[0046] Specifically, the No. 1 hydraulic rod 2 and the No. 2 hydraulic rod 3 are used to adjust the height of the supporting plate 6 to achieve the purpose of lifting at different heights, and then the driving motor 7 is used to adjust the sequence of the transfer plate 12 to facilitate the subsequent transfer of building materials, and the electric extension rod 8 is used to loosen the binding rope 5 for the building materials, and the micro electric telescopic rod 14 and the pressure sensor are used to control the contact state between the transfer plate 12 and the building materials, so as to control the sliding impact effect of the building materials.

[0047] The second implementation method:

[0048] Figure 9-10 It is shown that the interior of the winding column 111 is provided with an operating groove 113 whose height is smaller than that of the winding column 111, and a rotating rod 116 is installed through the inner center of the operating groove 113, and a second bevel gear 115 is fixedly sleeved on the surface of the rotating rod 116. A plurality of lead screws sliding through the interior of the operating groove 113 are installed on the surface of the winding column 111, and a first bevel gear 114 meshingly connected to the second bevel gear 115 is installed on the surface of one end of each lead screw located in the operating groove 113, and an arc-shaped side branch plate 112 is threadedly sleeved on the surface of the lead screw, and the side branch plate 112 is at the same height as the winding column 111, and the rotating rod 116 is rotatably connected to the winding column 111.

[0049] Different from the first embodiment, since the shape of the building material object is not uniform, there is a possibility that it gradually widens from one end to the other. In this state, the binding ropes 5 are loosened synchronously and to the same degree, which will result in a poorer degree of loosening in the wider part of the building material object. In this embodiment, the threaded area on the surface of the screw is located on the outside of the winding column 111.

[0050] Specifically, according to the cross-sectional shape of the building material object placed on the surface of the supporting plate 6 (such as Fig.11 As shown in the figure), the distance between the winding column 111 and the side branch plate 112 at different positions is adjusted, and the distance between the winding column 111 and the side branch plate 112 is increased in the area with a wider cross-section, so that the winding radius is increased (the rotating rod 116 is rotated, and the lead screw is driven to rotate under the meshing action of the bevel gear to adjust the distance of the side branch plate 112). Therefore, when the winding column 111 rotates by the same angle, the length of the bundle 5 released by the part with a larger winding radius is increased, thereby compensating for the problem of insufficient released length of the bundle 5.

[0051] In summary, when the present application is used to hoist building materials, the building materials can be first placed on the surface of the supporting plate 6, and then the building materials are tied with the binding rope 5. After the tying is completed, the excess part of the binding rope 5 is rolled up on the surface of the winding column 111, and then with the cooperation of the No. 1 hydraulic rod 2 and the No. 2 hydraulic rod 3, the supporting plate 6 is transferred to the specified position, the supporting plate 6 is slightly adjusted and the driving motor 7 is started, so that the transfer plate 12 can be flipped and kept flush with the supporting plate 6, and then the worker presses one end of the transfer plate 12 to form an inclined slope structure, and starts the electric extension rod 8 to indirectly loosen the binding rope 5, so that the building materials can be moved autonomously and transferred to the space of the building, reducing the safety hazards in the process of transferring the building materials to the space of the building during the hoisting process, and reducing the loosening procedure, which is simple and efficient.

[0052] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
