Abstract
Description
Technical Field
[0001] The utility model belongs to the field of building construction hoisting, and more specifically relates to a hoisting device for integral hoisting of a roof steel structure. Background Art
[0002] At present, during the construction of steel structure workshops, there are three main installation methods for the roof purlins of portal light steel structures: manual material distribution on the roof after whole bundle hoisting, single hoisting, and string hoisting. Manual material distribution after whole bundle hoisting is only applicable to structures with small purlin weight and convenient manual material distribution. This solution is not used for structures with heavy roof purlins. Single hoisting has low construction efficiency. String hoisting is more dangerous during implementation because the hoisting object is high and is affected by wind speed during the hoisting process. Utility Model Content
[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a roof steel structure integral lifting sling, which has the advantages of improving the purlin lifting efficiency and reducing high-altitude operations.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A roof steel structure integral lifting sling, including a lifting beam, the lifting beam is formed by splicing and welding four horizontal beams, a plurality of lifting ears are arranged on the lifting beam, a plurality of hooks are installed under the lifting beam, the hooks are symmetrically installed under two of the horizontal beams, the lifting beam and the hooks are movably connected by means of a pin shaft, and a detachable anti-hooking component is provided at the bent hook end of the hook.
[0006] The advantages of this solution are at least that: by adding multiple hooks under the lifting beam for lifting, multiple roof purlins can be lifted at one time, thereby improving the lifting efficiency; after lifting into place, the staff only needs to install the bolts at both ends in the aerial vehicle, which can reduce high-altitude operations and reduce the risk factor of the construction process; by providing an anti-unhooking component, the anti-unhooking component can prevent the hoisted roof purlins from being unhooked during lifting, thereby improving the safety during lifting; the pin shaft is used for active connection so that the horizontal beam and the hook can be relatively flexibly rotated and moved, thereby making the lifting operation more convenient.
[0007] The utility model is further configured as follows: at least four lifting ears are provided, and the four lifting ears are located at four corners of the lifting beam.
[0008] The advantages of this solution are at least that: the provision of four lifting ears allows lifting through four points during the lifting process, which greatly improves the stability during lifting.
[0009] The utility model is further configured as follows: the hook is a retractable hook.
[0010] The advantage of this solution is at least that when hoisting objects that are not on the same horizontal plane, the objects can be placed on the same horizontal plane through the adjustable hook, thereby ensuring stability during hoisting and improving the applicability of the hoisting sling.
[0011] The utility model is further configured as follows: the anti-hook-off assembly comprises: a thread arranged at the end of the hook, and an anti-hook-off block is threadedly connected to the thread.
[0012] The advantage of this solution is at least that the anti-dropping block is installed at the end of the hook by threaded connection, which is very convenient and quick to operate.
[0013] The utility model is further configured as follows: at least six hooks are arranged on the lower surfaces of the two horizontal beams, and there is a spacing between adjacent hooks.
[0014] The advantages of this solution are at least that it is convenient to hoist the roof purlins after they are assembled into a whole, the roof purlins after splicing have greater rigidity, and the hoisting process is safer.
[0015] The utility model is further configured as follows: reinforcing ribs for reinforcing the strength of the hoisting beams are welded at four corners of the four horizontal beams.
[0016] The advantage of this solution is at least that the provision of the reinforcing ribs improves the connection strength between two adjacent horizontal beams.
[0017] In summary, the utility model has at least the following advantages:
[0018] 1. By adding multiple hooks under the lifting beam for lifting, multiple roof purlins can be lifted at one time, thereby improving the lifting efficiency. After lifting in place, the staff only needs to install the bolts at both ends in the aerial vehicle, which can reduce high-altitude operations and reduce the risk factor of the construction process. By setting up anti-unhooking components, the anti-unhooking components can prevent the hoisted roof purlins from being unhooked during lifting, thereby improving the safety during lifting. The pin shaft can be used for active connection so that the horizontal beam and the hook can be relatively flexibly rotated and moved, making it more convenient to perform lifting operations;
[0019] 2. By setting up a retractable hook, when hoisting objects that are not on the same horizontal plane, the adjustable hook can be used to keep the objects on the same horizontal plane, ensuring the stability during hoisting and improving the applicability of the hoisting sling;
[0020] 3. At least six hooks are provided on the lower surface of two symmetrical horizontal beams. The advantage of this arrangement is that it is convenient to hoist the roof purlins after they are assembled into a whole. The roof purlins after splicing have greater rigidity, which makes the hoisting process safer. The setting of the reinforcement ribs improves the connection strength between the two adjacent horizontal beams. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0025] A roof steel structure integral lifting sling, such as Figure 1 As shown, it includes a hoisting beam 1, which is formed by splicing and welding four horizontal beams. A plurality of lifting ears 2 are provided on the hoisting beam 1. In some embodiments, at least four lifting ears 2 are provided. The four lifting ears 2 are located at the four corners of the hoisting beam 1. The hoisting is performed by four points, which greatly improves the stability during hoisting. It is worth mentioning that reinforcing ribs 5 for reinforcing the strength of the hoisting beam 1 are welded at the four corners of the four horizontal beams. The provision of the reinforcing ribs 5 improves the connection strength between two adjacent horizontal beams.
[0026] like Figure 1 As shown, a plurality of hooks 3 are installed below the lifting beam 1. The hooks 3 are symmetrically installed below two of the horizontal beams. The lifting beam 1 and the hooks 3 are movably connected by a pin shaft.
[0027] In some preferred embodiments, in order to facilitate the hoisting of the roof purlins after being assembled into a whole, at least six hooks 3 are provided on the lower surface of the horizontal beam, and there is a spacing between adjacent hooks 3. It is worth mentioning that the hooks 3 are retractable hooks 3. When hoisting objects that are not on the same horizontal plane, the adjustable hooks 3 can put the objects on the same horizontal plane, thereby ensuring stability during hoisting and improving the applicability of the hoisting sling.
[0028] like Figure 2As shown, in order to prevent the phenomenon of unhooking when hoisting the roof purlin, in some embodiments, a detachable anti-unhooking component 4 is provided at the bent hook end of the hook 3, and the anti-unhooking component 4 includes: a thread 401 set at the bent hook end of the hook 3, and an anti-unhooking block 402 is threadedly connected to the thread 401. The anti-unhooking block 402 is installed at the bent hook end of the hook 3 by connecting with the thread 401, so that the installation and disassembly of the anti-unhooking block 402 is more convenient and quick.
[0029] The working process and beneficial effects of the utility model are as follows:
[0030] By adding six hooks 3 under the lifting beam 1 for lifting, multiple roof purlins can be lifted at one time, and the roof purlins assembled into a whole can also be lifted, thereby improving the lifting efficiency. After lifting in place, the staff only needs to install the bolts at both ends in the aerial vehicle, which can reduce high-altitude operations and reduce the risk factor of the construction process. The anti-unhooking component 4 can prevent the hoisted roof purlin from unhooking during lifting, thereby improving the safety during lifting. The anti-unhooking block 402 is installed at the bent hook end of the hook 3 by using a threaded connection. This connection method is very convenient and quick in both disassembly and installation. The pin shaft is used for active connection so that the horizontal beam and the hook 3 can be relatively flexibly rotated and moved, thereby making it more convenient to perform lifting operations.
[0031] When it is necessary to hoist objects that are not on the same horizontal plane, the retractable hook 3 is adjusted to place the objects on the same horizontal plane, thereby ensuring stability during hoisting and improving the applicability of the hoisting sling.
[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
