Description

Technical Field

[0001] The utility model belongs to the technical field of laminated slab hoisting, and particularly relates to a laminated slab hoisting device. Background Art

[0002] The good integrity of the laminated slab is beneficial to enhancing the seismic performance of the building. The lower surface of the slab is flat, which is convenient for the decoration of the finishing layer. It is applicable to high-rise buildings and large-span buildings with relatively high overall stiffness requirements. During construction on the construction site, prestressed laminated slabs are generally customized in advance, transported to the site in the form of finished products, and then hoisted to the planned position by a tower crane. The traditional method of laminated slab construction is that the tower crane operator operates relying on the prompts and commands of on-site construction personnel. In the traditional hoisting process, only one laminated slab can be hoisted at a time, and most of them use steel ropes for hoisting, which is easy to damage the laminated slab and prone to accidents. Therefore, it is necessary to design a laminated slab hoisting device to solve the above problems. Content of the Utility Model

[0003] The utility model provides a laminated slab hoisting device that places laminated slabs in layers, reduces the labor intensity of operators, and improves the hoisting efficiency to solve the deficiencies of the prior art.

[0004] To achieve the above purpose, the utility model first proposes a laminated slab hoisting device, which includes a hoisting cage. The hoisting cage includes a bottom plate, a top plate, guardrails, and a protective door. The bottom plate and the top plate are connected as a whole through the guardrails vertically arranged on the left and right sides. Protective doors are also installed at the front and rear ends of the bottom plate between the two guardrails on both sides. The bottom plate, the top plate, the guardrails, and the protective door enclose a placement space for placing laminated slabs. The guardrails include multiple vertically arranged support rods and horizontally arranged crossbars. The support rods connect the bottom plate and the top plate as a whole. Between adjacent support rods, multiple crossbars are arranged along the height direction.

[0005] Horizontally arranged telescopic and resilient rods are symmetrically fixed on the opposite surfaces of the crossbars of the two guardrails. The telescopic and resilient rods are vertically arranged with respect to the crossbars. A vertical plate is fixed in the middle of the top surface of the movable end of the telescopic and resilient rod. The vertical plate is vertically arranged with respect to the telescopic and resilient rod. The vertical plate divides the top surface of the movable end of the telescopic and resilient rod into a surface A close to the crossbar and a surface B far from the crossbar. A first roller and a second roller are respectively installed on the surface B and on the side of the vertical plate 14 facing the surface B. The axis of the first roller is horizontally arranged and perpendicular to the crossbar. The axis of the second roller is perpendicular to the axis of the first roller. The first roller and the second roller enclose a support area for supporting the side of the laminated slab and allowing the laminated slab to slide.

[0006] When the utility model is in use, the operator first opens the protective door on one side, leans one side of the laminated board against the support area at the bottom layer of the guardrail on the same side. The second roller of the laminated board and the support area come into contact first, and the second roller is used to limit the moving direction of the laminated board. Then, the operator pushes the laminated board to compress the telescopic and resilient rod on this side, so as to support the other side of the laminated board on the corresponding support area at the bottom layer of the guardrail on the other side. At this time, both sides of the laminated board are in contact with the second roller, and the bottom is in contact with the first roller. Then, the operator pushes the laminated board again to make the laminated board completely enter the placement space. According to the above steps, from bottom to top, the laminated boards are placed in the support areas of each layer. Through this device, the laminated boards are placed in layers, which is convenient for the operator to load and unload the laminated boards, greatly reducing the labor intensity of the operator and improving the hoisting efficiency of the laminated boards.

[0007] In this embodiment, the telescopic and resilient rod includes a square rod, a first spring and a long rod. One end of the square rod is fixed on the cross bar and the other end is open. A square cavity is opened inside the square rod. A slider is slidably assembled inside the square cavity. One side of the slider is connected to the side of the square cavity close to the cross bar through the first spring. A long rod is installed on the other side of the slider. The long rod extends out from the opening of the square rod to form the movable end of the telescopic and resilient rod. When the telescopic and resilient rod contracts, the long rod pushes the slider to move inside the square cavity towards the cross bar direction, compressing the first spring, and making the distance between the vertical plates on the opposite side of the long rod larger. On the one hand, it can adapt to laminated boards of different widths. On the other hand, under the action of the first spring, both second rollers on both sides are in contact with the side wall of the laminated board to limit both sides of the laminated board and prevent the laminated board from shaking during hoisting, ensuring the integrity of the laminated board.

[0008] In this embodiment, the protective door includes a protective net. Long grooves matching the width of the protective door are opened at the front and rear ends of the bottom plate. An opening for the protective net to extend out is provided at the top of the long groove. A round rod is rotatably assembled in the long groove. The round rod is connected to the side wall of the long groove through a torsion spring. One side of the protective net is wound around the outside of the round rod, and the other side extends out from the opening of the long groove and is fixed on a positioning rod parallel to the round rod. Guide grooves vertically arranged and communicating with the long groove are opened on the opposite sides of the support rods on both sides of the protective door. Both ends of the positioning rod are slidably installed in the guide grooves, and the positioning rod is locked at the sliding height in the guide grooves through an elastic locking tongue.

[0009] When in use, through the sliding of the positioning rod in the guide groove, the lifting of the protective net is realized, achieving the effect of opening and closing the protective door. The torsion spring on the round rod is used to realize the return of the round rod, so that the protective net is wound around the side wall of the round rod to store the protective net.

[0010] In this embodiment, the elastic lock tongue includes a limit block, a second spring and a limit rod, and the guide groove is provided with a plurality of limit grooves arranged along the length direction and matching the limit block, and the two end portions of the positioning rod are coaxially provided with cylindrical grooves, and the limit blocks are slidably assembled in the cylindrical grooves, and the middle part of the positioning rod is provided with two slide grooves corresponding to the cylindrical grooves on both sides, and a shift block is slidably installed in the slide groove, and a through hole is coaxially provided in the positioning rod to connect the slide groove on the same side with the cylindrical groove. The limit rod is slidably installed in the through hole, one end of the limit rod is connected with the limit block, and the other end is connected with the shift block, and a second spring is also installed in the cylindrical groove and outside the limit rod, one end of the second spring is fixedly connected to the tail end of the limit block, and the other end is fixedly connected to the inner wall of the rear side of the cylindrical groove.

[0011] When in use, under the elastic action of the second spring, the limit block is inserted into the limit groove to limit the positioning rod, ensuring the normal deployment of the protective net and protecting the overlapping plate on the upper side of the bottom plate; when it is necessary to adjust the height of the protective net, the operator shifts the shift block, and the shift block drives the limit rod to slide, and the limit rod drives the limit block to disengage from the limit groove, and then the operator directly moves the positioning rod to the specified position, and then releases the shift block. Under the elastic action of the second spring, the limit blocks on both sides are inserted into the limit groove to limit the positioning rod, ensuring the safe use of the device.

[0012] In this embodiment, a hook is fixedly provided on the top surface of the top plate.

[0013] In this embodiment, a plurality of support seats are fixedly provided on the lower side of the bottom plate; the support seats provide support for the bottom plate, making it easy to load and unload the composite plate.

[0014] To sum up, the utility model has a stable structure and is easy to load and unload. The design of the guardrail and protective door provides the necessary safety protection for the operator and reduces the operation risk. The design of layered composite panels greatly reduces the labor intensity of the operator and improves the lifting efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] As Figure 1-6 shown, a laminated board hoisting device of the present invention includes a hoisting cage. The hoisting cage includes a bottom plate 1, a top plate 11, guardrails and a protective door. A hook 12 is fixedly provided on the top surface of the top plate 11, and a plurality of linearly distributed support seats 51 are fixedly provided on the lower side of the bottom plate 1; the support seats 51 provide support for the bottom plate 1, facilitating the loading and unloading of the laminated board.

[0025] The bottom plate 1 and the top plate 11 are connected as a whole by guardrails vertically arranged on the left and right sides. Protective doors are also installed at the front and rear ends of the bottom plate 1 between the two side guardrails. The bottom plate 1, the top plate 11, the guardrails and the protective door enclose a placement space for placing the laminated board. The guardrails include a plurality of vertically arranged support rods 10 and horizontally arranged cross bars 13. The support rods 10 connect the bottom plate 1 and the top plate 11 as a whole, and a plurality of cross bars 13 are arranged in the height direction between adjacent support rods 10;

[0026] On the opposite faces of the two guardrail crossbars 13, horizontally arranged telescopic and resilient rods are symmetrically fixed. The telescopic and resilient rods are arranged perpendicular to the crossbars 13. In the middle of the top surface of the movable end of the telescopic and resilient rod, a vertical plate 14 is fixed. The vertical plate 14 is arranged perpendicular to the telescopic and resilient rod. The vertical plate 14 divides the top surface of the movable end of the telescopic and resilient rod into surface A close to the crossbar 13 and surface B away from the crossbar. A first roller 15 and a second roller 16 are respectively installed on surface B and on the side of the vertical plate 14 facing surface B. The rotating shaft of the first roller 15 is horizontally arranged and perpendicular to the crossbar. The rotating shaft of the second roller 16 is arranged perpendicular to the rotating shaft of the first roller 15. The first roller 15 and the second roller 16 enclose a support area for supporting the side edge of the laminated plate and allowing the laminated plate to slide.

[0027] When the present utility model is in use, the operator first opens the protective door on one side, first leans one side of the laminated plate against the support area at the bottom layer of the guardrail on the same side. The laminated plate first abuts against the second roller 16 of the support area. The second roller 16 is used to limit the moving direction of the laminated plate. Then, the laminated plate is pushed to compress the telescopic and resilient rod on this side, so as to support the other side of the laminated plate on the support area at the bottom layer of the guardrail on the other side. At this time, both sides of the laminated plate abut against the second roller 16, and the bottom abuts against the first roller 15. Then, the laminated plate is pushed again to make the laminated plate completely enter the placement space. According to the above steps, from bottom to top, the laminated plates are placed in the support areas of each layer.

The long rod 24 extends out of the opening of the square rod 20 to form the movable end of the telescopic and resilient rod. The vertical plate 14 is fixed on the long rod 24. When the telescopic and resilient rod contracts, the long rod 24 pushes the slider 22 to move inside the square cavity 21 towards the crossbar 13 direction, so that the first spring 23 is compressed, making the distance between the vertical plates 14 on the opposite sides of the long rod 24 larger. On the one hand, it can adapt to laminated plates of different widths. On the other hand, under the action of the first spring 23, both sides of the second roller 16 abut against the side wall of the laminated plate to limit both sides of the laminated plate and avoid the shaking of the laminated plate during hoisting, ensuring the integrity of the laminated plate.
