[0002] During the construction process, some buildings need to be constructed in combination with prefabricated components. The use of prefabricated components can accelerate the construction process of the building. The hoisting of building components plays a vital role in construction projects. Through mechanized hoisting operations, the construction efficiency can be greatly improved and the construction period can be shortened. Especially in the construction of high-rise buildings and large-span structures in coastal areas, the application of hoisting technology can significantly accelerate the progress of the project.

[0003] At present, the hoisting method for prefabricated building components in coastal areas generally adopts the method of hook. After the component is hoisted to the designated position, it is necessary to manually release the hoisting lock. Since some buildings are high, if the hoisting position is at the edge of the building, it increases the safety hazard. In addition, after each component is hoisted, the lock needs to be manually released, which will greatly affect the hoisting efficiency and construction progress, and is not conducive to actual use.

[0017] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention. Example 1

[0018] like Figure 1-Figure 6 As shown, a decoupling mechanism for rapid lifting of building components comprises a shell 1 of a hollow structure, the shell 1 is U-shaped, two partitions 2 are fixedly connected to the inner wall of the shell 1 symmetrically, three support rings 3 are fixedly connected to the bottom surface of the shell 1 symmetrically, the inner walls of the support rings 3 are rotatably connected to screw sleeves 4, the screw sleeves 4 are internally threadedly connected to screw rods 5, the side walls of the shell 1 are provided with round holes corresponding to the screw rods 5, and the side walls of the screw sleeves 4 are provided with first transmission components and second transmission components; Specifically, the number of the single-side screw rods 5 is 3 or more, which can share the gravity of the building component. Compared with a single screw rod 5, using multiple screw rods 5 has higher strength.

[0019] The opposite ends of the screw rods 5 on both sides are abutted, the threads on the left and right screw rods 5 are opposite, and the screw rods 5 are matched with the screw sleeves 4.

[0020] like Figure 3 and Figure 4 As shown, the first transmission assembly includes a sprocket 6 fixedly connected to the side wall of the screw sleeve 4, and the sprockets 6 on the same side are transmission-connected with the same chain 7.

[0021] The screw sleeves 4 on the same side are connected by a sprocket 6 and a chain 7 so that the screw rods 5 on the same side can rotate synchronously. Since the threads on the screw rods 5 on both sides are arranged in opposite directions, when the screw sleeve 4 drives the screw rod 5 to rotate, the screw rods 5 on both sides move in opposite directions, so as to realize the locking or unlocking of the lifting lock buckle. In addition, the transmission method using the sprocket 6 and the chain 7 also has the following advantages: the chain drive meshes the roller part on the chain 7 with the tooth part of the sprocket 6, thereby ensuring the accuracy and stability of power transmission. This transmission method has no slippage phenomenon and can maintain an accurate average transmission ratio, so it is reliable and efficient; compared with other transmission methods, the chain drive can withstand a larger load, making it more widely used in the field of high-load and high-power transmission. This is due to the high-strength design of the chain 7 and the sprocket 6, which enables them to meet the needs of heavy-load transmission.

[0022] like Figure 3 and Figure 5 As shown, the second transmission assembly includes a first bevel gear 8 fixedly connected to the side wall of the intermediate screw sleeve 4, a second bevel gear 9 is meshed on the upper side of the first bevel gear 8, a transmission shaft 10 is fixedly connected to the top surface of the second bevel gear 9, the top end of the transmission shaft 10 passes through the partition 2 and is rotatably connected thereto, a first gear 11 is fixedly connected to the top end of the transmission shaft 10, a motor 12 is fixedly connected to the top surface of the inner cavity of the shell 1, a second gear 13 is fixedly connected to the output end of the motor 12, and the first gear 11 is meshed with the second gear 13.

[0023] Among them, the second transmission assembly does not use the motor 12 for direct drive but uses the first gear 11 and the second gear 13 for indirect transmission, which has the following advantages: the torque and speed output by the motor 12 are transmitted through the meshing of the gears, which can achieve the increase or decrease of speed and the amplification or reduction of torque, and the design and manufacturing precision of the gear transmission is high, which can provide a more accurate transmission ratio and position control. Since the motor 12 needs to drive the rotation of multiple screws 5 on the same side, the initial starting torque is relatively large, and the use of the first gear 11 and the second gear 13 can alleviate the initial torque, which plays a certain protective role on the motor 12.

[0024] like Figure 6 As shown, a positioning rod 14 is fixedly connected to the left end surface of the right screw rod 5 , and a positioning hole 15 is opened on the right side wall of the left screw rod 5 , and the positioning rod 14 corresponds to the positioning hole 15 .

[0025] Specifically, when the screw rods 5 on both sides lock the lifting lock buckle, the positioning rod 14 on the right screw rod 5 is inserted into the positioning hole 15 on the left screw rod 5. On the one hand, it increases the force balance between the screw rods 5 on both sides, and can be used for a long time. The ends of the screw rods 5 that are subjected to force for a long time will bend or deform. On the other hand, it can reduce the gap between the screw rods 5 on both sides to prevent the lifting lock buckle from being stuck in the gap between the screw rods 5.

[0026] like Figure 6 As shown, the side wall of the screw rod 5 is provided with a plurality of grooves 16, and movable wheels 17 are rotatably connected in each of the grooves 16. The grooves 16 are arranged in a staggered distribution or an equidistant distribution. When the lifting lock buckle needs to be unlocked, the screw rods 5 on both sides are retracted. At this time, the movable wheels 17 can be used to reduce the friction between the lifting lock buckle and the screw rod 5, so that the lifting lock buckle can be easily disengaged.

[0027] like Figure 1 and Figure 2 As shown, the left and right side walls of the housing 1 are respectively fixedly connected with protective cylinders 18 at the circular holes, and the screw rod 5 corresponds to the protective cylinders 18 .

[0028] Among them, when the screw 5 is in the unlocked state, the end of the screw 5 away from the center of the shell 1 is located in the protective tube 18, which can protect the screw 5. Even in rainy and snowy weather, it will not affect the normal use of the screw 5, reduce the corrosion of the screw 5 caused by natural factors, and improve the life and strength of the screw 5.

[0029] like Figure 1-Figure 3 As shown, the top surface of the housing 1 is equipped with a lifting ring 19. Among them, the lifting ring 19 is an existing common structure, and the user can replace it with other shapes or structures according to actual needs, and it will not be described in detail in the solution. Example 2

[0030] A method for unhooking a unhooking mechanism for rapid hoisting of a building component, the method comprising the following steps: S1: First, the housing 1 is hung on an external lifting device through the lifting ring 19. When the building component needs to be lifted, the lifting lock of the building component is placed on the inner side of the housing 1; S2: Then the motor 12 is started, the output shaft of the motor 12 drives the second gear 13 to rotate, the second gear 13 engages with the first gear 11 to drive the transmission shaft 10 to rotate, the transmission shaft 10 drives the second bevel gear 9 to rotate, the second bevel gear 9 engages with the first bevel gear 8 and drives the middle screw sleeve 4 to rotate, the middle screw sleeve 4 is driven by the sprocket 6 and the chain 7, so that the screw sleeve 4 drives the screw rods 5 on both sides to move relative to each other, which is used to fix the lifting lock buckle; S3: After the screw rods 5 on both sides abut against each other, the right screw rod 5 drives the positioning rod 14 to be inserted into the positioning hole 15; S4: When the building component needs to be unhooked, the motor 12 is started to rotate in the opposite direction, driving the screw 5 to move into the protective tube 18, and the screws 5 on both sides are opened, so that the lifting lock is disengaged from the inner side of the shell 1, and the lifting of the building component is completed.

[0031] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
