Technical Field
[0001] This invention relates to the technical field of building construction, specifically to a steel structure hoisting device for building construction and its usage method. Background Technology
[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. With the expansion of economic and cultural construction needs and the improvement of people's appreciation of architecture, large-span spatial steel structures are increasingly favored by designers due to their diverse forms, beautiful shapes, and good economy. However, when installing and using the above-mentioned steel structures, hoisting is required.
[0003] Chinese patent CN116040460A discloses a steel structure profile hoisting device, including a hoisting plate, limiting plates, a lead screw, a drive mechanism, brackets, a base plate, and a clamping mechanism. Two opposing limiting plates are positioned below the hoisting plate, perpendicular to it. A drive mechanism is connected to the lead screw, with both ends passing through the two limiting plates. The ends of the lead screw have opposite threads, and the lead screw is threadedly connected to the limiting plates. Brackets are rotatably connected to both ends of the lead screw, and these brackets are connected to the hoisting plate. Base plates are connected to the bottom ends of the opposing sides of the two limiting plates, and opposing clamping mechanisms are connected to the sides of the opposing sides of the two limiting plates. This invention allows for direct adjustment of the spacing between the limiting plates and the clamping mechanisms during use, thus securing the self-made steel structure packing device. This device is simple to operate, requires no repeated disassembly and assembly, and improves hoisting efficiency.
[0004] A Chinese patent with publication number CN112079244A discloses a steel structure component fixed hoisting device, comprising two parallel horizontal bars, end plates mounted on both sides of the horizontal bars by fixing bolts, the horizontal bars passing through the sliding bar grooves on both sides of the slider, a fixing seat one welded above the slider, a claw below the slider, a connecting seat directly above the middle of the horizontal bars, and fixing seats two welded on both sides of the connecting seat, with a connecting rod movably mounted between fixing seats one and fixing seats two via a shaft; this invention, when using this steel structure component fixed hoisting device, can quickly hoist and transport long strip-shaped steel structure components with grooves at the bottom, ensuring stable positioning of the steel structure component during hoisting, and making hoisting fast and convenient.
[0005] However, this steel structure hoisting device has the following drawbacks in practical use:
[0006] Existing steel structure hoisting equipment typically uses mechanical clamping and squeezing to install and fix the steel structure when hoisting steel structures of corresponding sizes, facilitating subsequent hoisting operations. However, in actual operation, the clamping mechanism for holding and positioning the steel structure usually clamps only the middle part of the steel structure. When it is necessary to hoist larger steel structures, it is difficult to guarantee stability. The swaying during the hoisting process can easily cause significant damage to the clamping mechanism, leading to the steel structure falling and affecting the service life and hoisting effect of the hoisting equipment. Summary of the Invention

[0022] As a preferred embodiment of the present invention, the tooth transmission assembly includes:
[0023] The second housing is bolted to the left and right sides of the hoisting frame. The interior of the second housing is hollow and a first transmission gear set is rotatably connected to its center.

[0026] A rotating gear is coaxially connected to a second transmission gear, and a lifting component is meshed with the side of the rotating gear, the lifting component being disposed through the second housing.
[0027] As a preferred embodiment of the present invention, the first transmission gear set has two sets of gears, and the transmission toothed belt, rotating gear and lifting component are all provided with two sets. The side of the lifting component is slidably connected through a protrusion and a recess inside the second housing.
[0028] The lifting component has teeth on its top side.
[0029] As a preferred embodiment of the present invention, the tooth lifting assembly includes:
[0030] A through hole is provided inside the lifting component and several through holes are provided at equal intervals. A lifting frame extending to the outside of the lifting component slides inside the lifting component.
[0031] The lifting frame and the lifting components are both provided with through-hole positioning pins, and a spring compression assembly is installed on the top of the lifting frame.
[0032] The lifting frame has an "L" shaped structure.
[0033] As a preferred embodiment of the present invention, the spring compression assembly includes:
[0034] A cavity is formed at the inner top of the lifting frame, and an extrusion member extending to the outer side of the cavity is slidably connected inside the cavity.

[0038] The steel structure building is positioned by the extrusion component and the limiting block.
[0039] A method for using a steel structure hoisting device for building construction includes the following steps:
[0040] S1. When hoisting a prefabricated steel structure building, first manually adjust the position of the lifting frame according to the size and area of the steel structure building. After the adjustment is completed, the position of the lifting frame is fixed by inserting the positioning pin into the through hole. At this time, the position and height of the spring compression component at the bottom of the lifting frame can be adjusted.
[0041] S2. Then, the entire device can be moved to the side of the steel structure building by moving the universal wheels at the bottom of the hoist. The hoisting frame can be moved to the side of the steel structure building by the hoisting components at the bottom of the hoist. Then, the servo motor can drive the screw drive assembly to operate and drive the transmission seat inside the screw drive assembly to move to the side of the top of the steel structure building. The cylinder can then drive the support seat to move, thus completing the support and positioning of the side of the top of the steel structure building.
[0042] S3. At the same time, when the screw drive assembly operates, it will drive the rotating shaft to rotate, which in turn drives the gear drive assembly connected to the rotating shaft to operate. The operation of the gear drive assembly will drive the lifting component connected inside the gear drive assembly to operate, and finally drive the spring compression assembly installed on the top of the lifting component to move up and down. That is, the spring compression assembly automatically moves to the outside of the bottom of the steel structure building and compresses and fixes the bottom of the steel structure building through the spring compression assembly.
[0043] S4. Finally, after the steel structure building is supported and positioned by the spring compression assembly and transmission seat, the casters can be activated by the control console to move the supported and positioned steel structure building to the corresponding installation position, automatically completing the hoisting and transportation of the steel structure building.
[0044] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:
[0045] 1. The steel structure hoisting device for building construction and its usage method, when hoisting and installing steel structure buildings, can drive the lead screw to rotate through a servo motor, thereby moving the transmission seat connected by ball bearings on the outside of the lead screw to press against both sides of the center of the top of the steel structure building, completing the initial fixation of the steel structure building. At the same time, when the lead screw rotates, it will drive the transmission toothed belt and the gear on its inner side to rotate through the rotating shaft connected to it, thereby driving the lifting components and the lifting frame to move synchronously, supporting the angled part at the bottom of the initially fixed steel structure building, completing the pressing and support fixation of the overall position of the steel structure building, ensuring the stability when actually hoisting heavy steel structure buildings, reducing the degree of damage to the hoisting clamping mechanism that performs pressing and support due to hoisting sway, and ensuring the effect of hoisting the steel structure building;
[0046] 2. The steel structure hoisting device for building construction and its usage method allow for manual adjustment of the distance between the lifting frame and the hoisting frame before hoisting and installing the steel structure building. This allows for adjustment based on the actual height of the steel structure building during hoisting. Furthermore, the device is operated by connecting and disassembling the steel structure using positioning pins and through holes, making it more convenient and allowing for real-time adjustments.
[0047] 3. The steel structure hoisting device for building construction and its usage method, when hoisting and installing steel structure buildings, uses a compression transmission seat on both sides of the center of the top of the steel structure building. The device has a support seat part driven by a cylinder inside. While actually squeezing and positioning the center of the top of the steel structure building, the bottom of the center of the top of the steel structure building can be lifted by lifting and squeezing the support seat, thereby completing the positioning operation of three parts (top, bottom and side) at the center of the top of the steel structure building, further improving the stability when hoisting the steel structure building;
[0048] 4. The steel structure hoisting device for building construction and its usage method: When hoisting and installing a steel structure building, the lifting frame supporting the bottom corner of the steel structure building is equipped with a pressing component. In actual operation, after the pressing component comes into contact with the bottom of the steel structure building, the pressing force after contact can push the pressing component to move and compress the pressing spring set on the side of the pressing component. Then, the spring force of the pressing spring can restore the pressure, pressing the left and right sides of the bottom corner of the steel structure building between the pressing component and the limiting block, realizing the positioning operation of three parts of the bottom corner of the steel structure building (bottom, left side and right side), further improving the stability when hoisting the steel structure building.

[0070] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.
[0071] Please see Figure 1 - Figure 10 A steel structure hoisting device for building construction includes a steel structure building 10 and a hoisting machine 20. The bottom of the hoisting machine 20 is equipped with casters 20i. The bottom of the hoisting machine 20 is connected to a hoisting assembly 30. Hoisting clamping mechanisms 40 are also installed on the bottom and sides of the hoisting frame 30i. The hoisting clamping mechanisms 40 clamp and fix the inner steel structure building 10. The hoisting clamping mechanism 40 also includes a screw drive assembly 50. The screw hoisting frame 30i is installed at the center of its bottom via positioning components 50i. The screw drive assembly 50 is driven by a servo motor 50a installed at the top. The positioning components 50i are installed on the left and right sides of the hoisting frame 30i. The screw drive assembly... The 50 clamps and fixes the top of the inner steel structure building 10; the toothed transmission assembly 60 is installed on the left and right sides of the screw transmission assembly 50, and a rotating shaft 60i is installed and fixed at the center of the toothed transmission assembly 60, which is installed on the left and right sides of the screw transmission assembly 50; the toothed lifting assembly 70 is installed inside the toothed transmission assembly 60 and is driven by the toothed transmission assembly 60; a spring compression assembly 80 is installed at the bottom of the toothed lifting assembly 70, which clamps and fixes the bottom of the inner steel structure building 10; the hoisting assembly 30 and the hoisting clamping mechanism 40 are both electrically connected to the control console.
[0072] The working principle described above is as follows: When hoisting the steel structure building 10, the device is first moved to the corresponding side of the steel structure building 10 via the casters 20i, and then the hoisting frame 30i is moved above the steel structure building 10 by the hoisting machine 20. Afterwards, the servo motor 50a is started via the control console, driving the screw drive assembly 50 connected to its output end to operate, pressing and fixing the center portions of both sides of the top of the steel structure building 10. Simultaneously, when the screw drive assembly 50 operates, it drives the rotating shaft 60i connected to its output end to rotate, thereby driving the gear drive assembly 60 connected to the side of the rotating shaft 60i to operate, driving the gears... The lifting component 606, which is internally engaged with the tooth transmission assembly 60, rises, thereby driving the spring compression assembly 80 at the bottom of the lifting component 606 to move. This provides support and spring compression to the side of the bottom corner of the steel structure building 10, ultimately completing the clamping and positioning of the overall position of the steel structure building 10. This operation can be driven by only one set of servo motors 50a, making it simple and convenient to operate. It can simultaneously clamp the center part of the top and the corner part of the bottom of the steel structure building 10, improving stability when hoisting larger steel structure buildings 10 and reducing the probability of swaying during hoisting.
[0073] For details, please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 To facilitate the winding and unwinding of the cable 302 and the adjustment of the position of the lifting frame 30i, the lifting assembly 30 includes a take-up reel 301, which is installed at the bottom of the lifting frame 30i, and the cable 302 extending to the outside of the take-up reel 301 is provided inside the take-up reel 301; and an installation component 303, which is installed at the bottom of the cable 302 and on the outside of the lifting frame 30i; wherein, there are four sets of both the cable 302 and the installation component 303.
[0074] The steel structure hoisting device for building construction of the present invention can control the operation of the take-up reel 301 through the control console during the actual hoisting of the steel structure building 10. The device can also adjust the position of the hoisting frame 30i connected to the bottom of the cable 302 through the mounting component 303 and the position of the steel structure building 10 after being clamped inside the hoisting frame 30i, thereby improving the stability of the steel structure building 10 during hoisting.

[0076] The steel structure hoisting device for building construction of the present invention starts the operation of the servo motor 50a through the control console, which drives the first bevel gear 502 connected to its output end to rotate, thereby driving the two sets of second bevel gears 503 meshing on the left and right sides of the first bevel gear 502 to rotate synchronously in the same direction. At this time, the rotation of the second bevel gear 503 will drive the transmission screw 504 installed inside to rotate, thereby driving the transmission seat 505 connected to the side of the transmission screw 504 through the ball to move. The internal spiral grooves of the transmission screw 504 are opposite in direction. When the two sets of transmission screws 504 rotate synchronously in the same direction, the two sets of transmission seats 505 set on their outer sides will move towards each other.
[0077] For details, please refer to the following: Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 In order to support the bottom of the top of the steel structure building 10, a cylinder 505a is installed in the inner bottom of the transmission seat 505.

[0080] In the steel structure hoisting device for building construction of the present invention, when the transmission screw 504 rotates, it drives the rotating shaft 60i installed at its bottom to rotate, which in turn drives the first transmission gear set 602 connected to the side of the rotating shaft 60i to rotate. At this time, the rotation of the first transmission gear set 602 drives the two sets of transmission toothed belts 603 set on its outer side to drive, which in turn drives the second transmission gear 604 meshed with the inner side of the transmission toothed belts 603 to rotate. The rotation of the second transmission gear 604 drives the rotating gear 605 coaxially connected to it to rotate, which in turn drives the lifting component 606 connected to the side of the rotating gear 605 through the toothed part 606b to move up and down. The design of the protrusion 606a ensures the stability of the lifting component 606 moving up and down inside the second housing 601.
[0081] For details, please refer to the following: Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10In order to hoist steel structure buildings 10 of different heights, the toothed lifting assembly 70 includes through holes 701. The through holes 701 are opened inside the lifting component 606 and are equally spaced. A lifting frame 702 extending to the outside of the lifting component 606 slides inside the lifting component 606. The lifting frame 702 and the lifting component 606 are both provided with positioning pins 703 through the through holes 701. A spring compression assembly 80 is installed on the top of the lifting frame 702. The lifting frame 702 has an "L" shaped structure.
[0082] The steel structure hoisting device for building construction of the present invention can, when hoisting steel structure buildings 10 of different heights, manually adjust the position of the lifting frame 702 inside the lifting component 606 and use the positioning pin 703 to insert into the through hole 701 to complete the positioning of the lifting frame 702, thereby adjusting the distance between the lifting frame 702 and the second box 601.
[0083] For details, please refer to the following: Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 In order to compress and support the two sides of the bottom of the steel structure building 10, the spring compression assembly 80 includes a cavity 801, which is opened in the inner top of the lifting frame 702. The cavity 801 is slidably connected to the cavity 801 and extends to the outside of the cavity 801. The compression spring 803 located on the side of the lifting frame 702 is also installed on the back of the compression component 802. The limiting block 804 is installed on the side of the lifting frame 702 and located on the side of the cavity 801. The limiting block 804 is located directly below the transmission seat 505. The limiting block 804, the compression component 802 and the top of the lifting frame 702 form a concave shape. The steel structure building 10 is positioned by compression between the compression component 802 and the limiting block 804.
[0084] In the steel structure hoisting device for building construction of the present invention, when the lifting component 606 rises, it will drive the lifting frame 702 fixed inside by the positioning pin 703 to move synchronously. At this time, the lifting frame 702 will contact the two sides of the bottom of the steel structure building 10, and drive the pressing component 802 in contact with it to slide inside the cavity 801, pressing the pressing spring 803. Then, through the elastic force of the pressing spring 803, the two sides of the bottom of the steel structure building 10 are pressed between the pressing component 802 and the limiting block 804, thus completing the support and positioning of the two sides of the bottom angle of the steel structure building 10.
[0085] A method for using a steel structure hoisting device for building construction includes the following steps:
[0086] S1. When hoisting the prefabricated steel structure building 10, firstly, according to the size and area of the steel structure building 10, manually adjust the position of the lifting frame 702. After the adjustment is completed, the position of the lifting frame 702 is fixed by inserting the positioning pin 703 into the through hole 701.
