Abstract
Description
Technical Field
[0001] The embodiments disclosed herein belong to the field of structural component installation technology, specifically relating to a lifting hook detacher and a structural component installation method. Background Technology
[0002] There are a lot of high-altitude hoisting operations during the steel structure installation process. When hoisting steel components, the steel components and hoisting equipment are usually temporarily connected by shackles. After the steel components are installed in place, the hoisting equipment needs to be separated from the steel components. This process is commonly known as unhooking.
[0003] There are generally two methods for unhooking. The first method is for workers to climb to the shackle position using a steel ladder pre-installed on the steel column to complete the unhooking. This method requires the installation of a temporary ladder on the steel column, and workers should wear safety belts and fall arrestors during the climb. This process has high safety risks and high labor intensity. The second method is for workers to operate an aerial work platform to rise to the shackle position to complete the unhooking. Although this method significantly reduces safety risks, it greatly increases equipment costs, and the location of the aerial work platform is easily restricted by the installation site environment.
[0004] In view of this, the inventor designed a hook unloader for hoisting, which connects steel components to hoisting equipment. The hook unloader is controlled by workers on the ground. When the steel components need to be unhooked after installation, workers only need to stand on the ground and perform simple operations to complete the unhooking. This greatly reduces safety risks and equipment costs, reduces the labor intensity of workers, and improves construction efficiency. Summary of the Invention

[0025] The items include:
[0026] The lifting lug of the structural component is inserted between the two free ends of the shackle body, and the lifting traction component is wound around the shackle body.
[0027] Optionally, after the hook remover and the lifting lug of the structural member are disengaged, the other end of the tension member is released so that the blocking member returns to the locked position under the preload of the elastic member.
[0028] Optionally, the structural component is a steel column, and the fixing component is a steel column base nut.

[0039] To enable those skilled in the art to better understand the technical solutions of this disclosure, the disclosure will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0040] On the one hand, such as Figures 1 to 3 As shown, a lifting hook undock 100 includes: a shackle body 110; a housing 120 fixedly connected to the outside of any free end 111 of the shackle body 110, with an opening at one end surrounding a connecting hole (not shown) corresponding to the free end 111; an insert 130 movably inserted through the connecting holes of both free ends 111 of the shackle body 110, with one end extending toward the housing 120 and used to connect a tension member 200; a blocking member 140 fixedly connected to the insert 130 and located inside the housing 120, the blocking member 140 being switchable between a locked position and a released position; and an elastic member 150 fixed inside the housing 120 with a preset preload, one end connected to the insert 130 and the other end connected to the inner wall of the housing 120.
[0041] In the free state, the blocking member 140 is in the locked position, and under the pre-tightening force of the elastic member 150, the blocking member 140 abuts against the outside of the corresponding free end 111 of the shackle body 110. When the insert 130 is pulled towards the end extending towards the housing 120, the insert 130 overcomes the pre-tightening force of the elastic member 150 and drives the blocking member 140 to the release position, so that the two free ends 111 of the shackle body 110 are in an unoccupied state.
[0042] Specifically, such as Figures 1 to 3 As shown, a housing 120 is fixedly connected to the outside of the free end 111 below the shackle body 110. The upper opening of the housing 120 surrounds the outside of the communicating hole of the free end 111 below the shackle body 110. The insert 130 passes through the communicating holes of the two free ends 111 of the shackle body 110 respectively, and one end of the insert 130 extends into the housing 120. The blocking member 140 is disposed inside the housing 120 and connected to the insert 130. One end of the elastic member 150 is connected to the insert 130, and the other end is connected to the inner wall of the housing 120. During the application of the hook remover 100, in the free state, due to the pre-tightening force of the elastic member 150, the blocking member 140 abuts against the outside of the communicating hole of the free end 111 below the shackle body 110. At this time, the upper end of the insert 130 passes through the communicating hole of the two free ends 111 of the shackle body 110, and the blocking member 140 is in the locked position.
[0043] When the tension member 200 is connected to the end of the insert 130 extending into the housing 120 (i.e., the lower end of the insert 130), and the tension member 200 is pulled downwards, the tension member 200 overcomes the preload of the elastic member 150 and drives the insert 130 to move downwards. The upper end of the insert 130 moves downwards and passes through the connecting holes of the two free ends 111 of the shackle body 110. At the same time, the blocking member 140 moves downwards with the insert 130 to the release position. At this time, the two free ends 111 of the shackle body 110... When the shackle body 110 is in an empty state, the hoisting traction component 400 can be wrapped around the shackle body 110, the hook remover 100 can be aligned with the lifting lug 310 of the structural component, the tension component 200 can be released so that the blocking component 140 can be restored to the locked position under the rebound of the elastic component 150, and the upper end of the insert 130 passes through the connecting hole of the two free ends 111 of the shackle body 110 and the lifting lug 310 of the structural component. The hook remover 100 connects the hoisting traction component 400 and the lifting lug 310 of the structural component at the same time.
[0044] During hoisting, the lifting traction component 400 is used to lift and raise the hook detacher 100, thereby lifting and raising the lifting lug 310 of the structural component, and then lifting and raising the structural component. After the structural component is lifted and raised, the pulling component 200 is pulled down. The pulling component 200 overcomes the preload of the elastic component 150 and drives the insert 130 to move downward. The upper end of the insert 130 moves downward and passes through the connecting hole of the two free ends 111 of the shackle body 110. At the same time, the blocking component 140 follows the insert 130 downward to the release position. At this time, the two free ends 111 of the shackle body 110 are in an empty state, and the hook detacher 100 can be disengaged from the lifting lug 310 of the structural component.
[0045] The lifting hook unloader of the present disclosure, through the provided shackle body, housing, insert, blocking member and elastic member, can lift structural components and avoid climbing to a height to unhook them after lifting, thereby reducing construction safety risks and construction costs and improving construction efficiency. At the same time, the designed hook unloader is small in size and light in weight, making it more convenient to use.
[0046] For example, such as Figures 1 to 3 As shown, one end of the insert 130 extending toward the housing 120 protrudes from the opening at the other end of the housing 120.
[0047] Furthermore, the elastic element 150 is wound around the insert 130, one end of the elastic element 150 is fixed to the blocking element 140, and the other end is fixed to the bottom wall of the housing 120.
[0048] Specifically, such as Figures 1 to 3As shown, in the free state, the blocking member 140 is in the locked position, the upper end of the insert 130 passes through the connecting hole of the two free ends 111 of the shackle body 110, and the lower end of the insert 130 extends out of the lower end opening of the housing 120. When the pulling member 200 is connected to the lower end of the insert 130 and the pulling member 200 is pulled downward, the pulling member 200 overcomes the preload of the elastic member 150 and drives the insert 130 to move downward. The blocking member 140 moves downward with the insert 130, and the elastic member 150 is compressed between the blocking member 140 and the bottom wall of the housing 120 until the blocking member 140 reaches the release position.
[0049] It should be noted that the insert and elastic element can also be configured in other forms. For example, in the free state, the blocking element 140 is in the locked position, the upper end of the insert 130 passes through the connecting hole of the two free ends 111 of the shackle body 110, and the lower end of the insert 130 is located inside the housing 120. One end of the elastic element 150 is fixed to the insert 130, and the other end is fixed to the inner wall of the housing 120. When the pulling element 200 is connected to the lower end of the insert 130 and the pulling element 200 is pulled downward, the pulling element 200 overcomes the preload of the elastic element 150 and drives the insert 130 to move downward. The blocking element 140 moves downward with the insert 130, and the elastic element 150 is compressed between the insert 130 and the inner wall of the housing 120 until the blocking element 140 reaches the release position. The embodiments of this disclosure do not limit the specific configuration of the insert and elastic element.
[0050] The lifting unhooking device of the present disclosure, through the provided insert and elastic member, can control the blocking member to be in a locked position in a free state. When the insert moves and compresses the elastic member, it controls the blocking member to move to the release position, avoiding the need to climb to a height for unhooking operations. The lifting and unhooking separation of structural components can be achieved simply by pulling the tension member, reducing construction safety risks and construction costs, and improving construction efficiency. At the same time, the designed unhooking device is small in size and light in weight, making it more convenient to use.
[0051] For example, such as Figures 1 to 3 As shown, the hook remover 100 also includes a connecting portion 160. The connecting portion 160 is fixed to one end of the insert 130 extending toward the housing 120. The connecting portion 160 has a through hole 161 along its thickness direction. The through hole 161 is used to connect one end of the pulling member 200, and the other end of the pulling member 200 is used to apply force for pulling.
[0052] Specifically, such as Figures 1 to 3As shown, a connecting portion 160 with a through hole 161 is fixedly connected to the lower end of the insert 130. One end of the tension member 200 passes through the through hole 161 and is connected to the connecting portion 160. The other end of the tension member 200 is used to apply force to pull and overcome the preload of the elastic member 150. The connecting portion facilitates the connection of the tension member.
[0053] It should be noted that the insert 130 can be a pin, the elastic element 150 can be a spring, and the tension element 200 can be a cable. Of course, the insert, elastic element, and tension element can also be other specific parts, and this embodiment does not impose any specific restrictions on them.
[0054] On the other hand, such as Figure 4 As shown, this disclosure also provides a method for installing structural components, using the hook remover 100 described above. The specific structure of the hook remover 100 can be found in the preceding descriptions and will not be repeated here. The method includes:
[0055] S11. The lifting lugs and lifting traction components of the structural member are connected by the hook unhooking device, and one end of the tension member is connected to the end of the insert extending toward the housing.
[0056] Refer to together Figure 2 and Figure 3 , Figure 5 and Figure 6 In this step, a tension member 200 is connected to the end of the insert 130 extending towards the housing. By pulling the tension member 200, the lifting lug 310 of the structural component can pass through the insert 130 between the two free ends 111 of the shackle body 110, and the lifting traction member 400 is wound around the shackle body 110. It should be noted that, as Figure 6 As shown, the lifting traction component 400 can be configured as a cable, which can be used to lift and raise the unhooking device 100 and the structural component using lifting equipment. The following description uses a steel column as an example of a structural component.
[0057] S21 uses the lifting traction component to lift the interconnected unhooking device and the structural component.
[0058] Refer to together Figure 5 and Figure 7 In this step, the steel column is slowly lifted with the column base plate as the center and the length of the steel column as the radius. During the lifting process, the tension member 200 is always in a free state.
[0059] S31. After the structural component is hoisted into place, the fixing component is installed to secure the structural component.
[0060] Refer to together Figure 5 and Figure 8After the steel column is hoisted into place, steel column base nuts are installed at the bottom of the steel column to fix it in place.
[0061] S41. Pull the other end of the tensioning member to move the blocking member to the release position and unhook it, so that the unhook device and the lifting lug of the structural member are disengaged.
[0062] Refer to together Figure 3 and Figure 9 After the steel column is installed and fixed, the operator pulls the other end of the tension member 200 to move the blocking member 140 of the hook undock 100 to the release position. By pulling the tension member 200, the hook undock 100 can be disengaged from the lifting lug 310 of the structural member to achieve the hook undock operation. After the hook undock is completed, the hook undock 100 is still wrapped around the hoisting traction member 400.
[0063] Furthermore, such as Figure 1 and Figure 2 As shown, after the hook remover 100 and the lifting lug 310 of the structural member are disengaged, the other end of the tension member 200 is released so that the blocking member 140 returns to the locked position under the pre-tightening force of the elastic member 150.
[0064] Specifically, such as Figure 1 and Figure 2 As shown, after the unhooking operation is completed, the pull on the other end of the tension member 200 is released. The blocking member 140 of the unhooker 100 returns to the locked position under the rebound action of the elastic member 150. At this time, the lifting traction member 400 is still wrapped around the shackle body 110, making it convenient to continue using the unhooker 100 for lifting and unhooking next time. The elastic member can control the blocking member to automatically reset to the locked position after the unhooking operation is completed, so as to connect to the lifting traction member for convenient use next time. In addition, the blocking member of the unhooker in the free state being in the locked position can also ensure the safety of lifting and prevent falling.
[0065] The structural component installation method of the present disclosure can hoist and lift the structural component, and after hoisting and lifting, pull the detachment device from the structural component by pulling the detachment device, avoiding the need to climb to a height for detachment work, reducing construction safety risks and construction costs, and improving construction efficiency.
[0066] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of this disclosure, and this disclosure is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of this disclosure, and these modifications and improvements are also considered to be within the scope of protection of this disclosure.
