Description

Technical Field

[0001] The invention relates to the technical field of hoisting fixtures, and in particular to a prefabricated assembled aluminum alloy building hoisting device. Background Art

[0002] In recent years, prefabricated buildings with aluminum alloy components as the main load-bearing components have begun to attract attention because aluminum alloy materials are stronger, lighter, and more corrosion-resistant than concrete and steel. Precisely because of their high strength and light weight, aluminum alloy materials have the conditions for optimized lifting.

[0003] The prefabricated construction model usually requires the prefabrication of the main components in the factory, which are then transported to the construction site and then hoisted to the designated location and installed through lifting and other technical means. There are many traditional lifting methods. One is to use a lifting rope as a lifting part and a supporting part, that is, to set the lifting rope loop on the part to be lifted, and then use the lifting hook to hook the end of the lifting rope. However, this lifting method is prone to the risk of the hanging part slipping off the lifting rope due to the offset of the center of gravity of the hanging part, causing the risk of falling; another lifting method is to use a lifting clamp to clamp the edge of the hanging part, and then use a lifting machine to hook the lifting clamp. This lifting method also has some technical problems when installing the lifting clamp. When using the clamp, it is necessary to first lift the component to be hoisted to a certain height and then insert the lifting clamp. Since some components to be hoisted are too heavy, it is easy to pinch hands during the lifting process, causing personal injury. In addition, the component to be hoisted is in close contact with the placement plane when it is not lifted. The auxiliary lifting piece needs to be inserted between the component to be hoisted and the placement platform to break the contact between the two before the seesaw can be inserted to lift the component to be hoisted. However, when the auxiliary lifting piece is inserted, it is easy to cause damage to the edge of the component to be hoisted, affecting its appearance when used.

[0004] Therefore, in order to ensure the stability and safety of the hoisting, and to lift the component and install the hoisting fixture without damaging the surface of the component, it is urgent to design a prefabricated aluminum alloy building hoisting device. Summary of the invention

[0028] Example

[0029] like Figures 1 to 3 As shown, the present invention provides a prefabricated and assembled aluminum alloy building hoisting device, including a hoisting device 200 installed on a component 100 to be hoisted, and the hoisting device 200 is made of steel as a whole to ensure firmness and durability. Preferably, the hoisting device 200 includes a lifting lug 210, a hoisting rope 220, a lifting auxiliary component 230 and a supporting component 240, the lifting auxiliary component 230 is buckled at the four corners of the component 100 to be hoisted (it is worth mentioning that the component 100 to be hoisted here is a square plate), and is tightly fitted with the three adjacent mutually vertical surfaces at the corners of the component 100 to be hoisted, the lifting lug 210 is installed on the lifting auxiliary component 230, the lifting rope 220 is bolted to the lifting lug 210, and the four strands of the lifting rope 220 converge to a position above the middle of the component 100 to be hoisted, and the supporting component 240 is rotatably installed on the lifting auxiliary component 230;

[0030] During hoisting, the crane first hooks the hoisting hook to the connection knot of the hoisting rope 220 gathered above the middle of the component to be hoisted 100. When the crane hooks the hoisting rope 220 and pulls it upward, a hoisting tension is generated along the hoisting rope 220. Since the lifting auxiliary component 230 is wrapped around the corner of the component to be hoisted 100 and fits tightly with the three adjacent perpendicular planes on the corner of the component to be hoisted 100, when the hoisting rope 220 is lifted upward by the crane, according to the principle of action and reaction force, a reaction force (limiting force) is generated in the opposite direction of the hoisting tension. A friction force in the horizontal direction along the upper end surface of the component 100 to be hoisted and a downward pressure perpendicular to the horizontal surface of the component 100 to be hoisted are generated so that the lifting auxiliary component 230 clamps the component 100 to be hoisted; when the component 100 to be hoisted is lifted to a certain height by the lifting auxiliary component 230 using the reaction force (it is worth mentioning that the lifting height is higher than the thickness of the supporting component 240), the supporting component 240 is flipped and buckled down, and the component 100 to be hoisted is supported. The overall shape of the installed lifting device 200 is the same as that of a lifting clamp, that is, it is clamped on the edge of the component. This type of lifting device 200 has a simple structure, is easy to operate, and is stable and safe during the lifting process. It does not cause problems such as pinching the hand and causing scratches and wear to the plate surface of the component to be hoisted in the traditional lifting steps of first lifting the component 100 to be hoisted and then buckling it into the lifting clamp.

[0031] In some preferred embodiments, the lifting auxiliary component 230 includes three mutually perpendicular first laminating panels 231, second laminating panels 232 and third laminating panels 233, wherein the first laminating panel 231 is tightly fitted with the upper end surface of the component to be hoisted 100, and the second laminating panel 232 and the third laminating panel 233 are tightly fitted with the two side surfaces adjacent to the upper end surface of the component to be hoisted 100, respectively. Among them, the contact surfaces of the first laminating panel 231, the second laminating panel 232 and the third laminating panel 233 with the component to be hoisted 100 are all provided with an anti-skid rubber layer. The provision of the anti-skid rubber layer can increase the friction between the laminating panel and the board surface of the component to be hoisted 100, ensuring a more stable and firm process during lifting.

[0032] In some preferred embodiments, the second bonding panel 232 and the third bonding panel 233 are square panels, the cross section of the first bonding panel 231 is triangular, and the adjacent two sides of the first bonding panel 231, the second bonding panel 232 and the third bonding panel 233 are connected to each other. The ear 210 is rotatably mounted on the first bonding panel 231 through the mounting block 211.

[0033] In some preferred embodiments, the supporting assembly 240 includes a connecting arm 241, a rotating shaft 242, a supporting ring arm 243 and a locking bolt 244. The rotating shaft 242 is provided on the inner side of the connecting arm 241. The connecting arm 241 is rotatably mounted on the side surfaces of the second bonding panel 232 and the third bonding panel 233 through the rotating shaft 242. A sliding groove is provided on the connecting arm 241. The supporting ring arm 243 is slidably arranged on the connecting arm 241. A limit stop is provided on the end of the supporting ring arm 243. The limiting plate can prevent the supporting ring arm 243 from sliding off the connecting arm 241. One end of the supporting ring arm 243 is connected to the connecting arm 241 installed on the second fitting panel 232, and the other end is connected to the connecting arm 241 installed on the third fitting panel 233. The connecting arm 241 is provided with a threaded hole, and the locking bolt 244 is installed in the threaded hole. The end of the locking bolt 244 abuts against the supporting ring arm 243 to fix the supporting ring arm 243 on the connecting arm 241. The supporting assembly 240 can be adjusted accordingly according to the thickness of the component 100 to be hoisted.

[0034] It is worth mentioning that the insertion end of the supporting ring arm 243 is set in a slope. The transition setting of the slope can avoid scratching the bottom surface of the plate when buckled into the bottom surface of the component to be hoisted 100, affecting the overall beauty of the prefabricated aluminum alloy component. The setting of the slope can facilitate the supporting ring arm 243 in the lifting auxiliary component 230 to be better clamped under the component to be hoisted 100.

[0035] Initially, the crane lifts the component 100 to be hoisted to a thickness greater than the thickness of the supporting ring arm 243 (the lifting height only needs to be higher than the clamping thickness of the lifting fixture instead of using the entire force for lifting), drives the supporting ring arm 243 to flip and clamp to the bottom of the component 100 to be hoisted, and then slowly descends to make the bottom surface of the component 100 to be hoisted fit the supporting ring arm 243, drives the lifting auxiliary component 230 and the supporting ring arm 243 to clamp the component 100 to be hoisted, and tightens it with the locking bolt 244, and finally the hoisting can be carried out.

[0036] A hoisting operation step of a prefabricated aluminum alloy building hoisting device:

[0037] The operator first buckles the lifting auxiliary component 230 on the four corners of the component 100 to be hoisted, at this time, the supporting component 240 is in an unfastened state, that is, it is flipped outward, and when the buckle is engaged on the corner of the component 100 to be hoisted, ensure that the lifting auxiliary component 230 is tightly fitted with the three adjacent mutually vertical surfaces at the corners of the component 100 to be hoisted; the lifting rope 220 is bolted to the lifting ear 210, and the four strands of the lifting rope 220 are gathered to the position above the middle of the component 100 to be hoisted, and the lifting rope 220 connection knot gathered above the middle of the component 100 to be hoisted is hooked by the crane. When the crane hooks the lifting rope 220 and pulls it upward, a lifting tension is generated along the lifting rope 220. Since the lifting auxiliary component 230 is wrapped on the corner of the component 100 to be hoisted and is connected to the The three adjacent perpendicular planes on the corners of the component 100 are tightly fitted, so when the lifting rope 220 is lifted upward by the crane, according to the principle of action and reaction force, a reaction force (limiting force) is generated in the opposite direction of the lifting tension, and the reaction force is divided into a friction force in the horizontal direction along the upper end surface of the component 100 to be lifted and a downward pressure perpendicular to the horizontal surface of the component 100 to be lifted so that the lifting auxiliary component 230 clamps the component 100 to be lifted; when the component 100 to be lifted is lifted to a certain height by the lifting auxiliary component 230 using the reaction force (it is worth mentioning that the lifting height is higher than the thickness of the supporting component 240), the supporting component 240 is flipped over and buckled down, and the component 100 to be lifted is supported, and the overall shape of the installed lifting device 200 is the same as the lifting clamp type, that is, it is clamped on the edge of the component.

[0038] In summary, the present invention provides a prefabricated and assembled aluminum alloy building lifting device, which utilizes the principle of action and reaction force to assist the lifting of components and install them into the lifting clamp. This lifting structure is simple, easy to operate, and stable and safe during the lifting process. There will be no problems of pinching hands and causing scratches and wear to the plate surface of the component to be lifted, such as the traditional lifting steps of first lifting the component 100 to be lifted and then buckling it into the lifting clamp. The lifting device provided by the present invention can be adjusted accordingly according to the thickness of the component to be lifted, and its applicability is good.

[0039] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
