Description

Technical Field

[0001] This utility model belongs to the field of hoisting technology, specifically relating to a steel structure hoisting equipment. Background Technology

[0002] Steel structure hoisting is the process of transporting prefabricated steel components to a designated location for installation using equipment such as cranes. Key steps include preparation, trial hoisting, adjustment, and securing. Using equipment such as tower cranes, crawler cranes, or floating cranes, precise measurements and positioning ensure accurate alignment of each component. Strict control over safety and precision is required throughout the process to guarantee structural stability and construction quality. This operation demands a high degree of coordination and professional technical guidance.

[0003] Existing steel structure installations utilize conventional lifting equipment, which is inconvenient for controlling the structure's posture when hoisting long, strip-shaped components. This can easily lead to rotation, safety accidents, and it's difficult to accurately position the components. Therefore, a new type of steel structure hoisting equipment is needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a steel structure hoisting device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A steel structure hoisting device includes a telescopic boom extending from a hoisting device. A horizontal bar is rotatably connected to the telescopic boom. A rotating assembly is connected to the end of the horizontal bar furthest from the telescopic boom. An output component of the rotating assembly is connected to a mounting base. An extension assembly is mounted on the mounting base. The extension assembly includes: a threaded rod with opposite threads rotatably installed in the inner cavity of the mounting base; a worm gear is coaxially fixedly sleeved on the middle of the threaded rod, and the worm gear meshes with a worm. A second motor with its output end coaxially fixedly connected to the worm is mounted on the outer wall of the mounting base. Telescopic rods are threadedly connected to both ends of the threaded rod, and the telescopic rods are slidably connected to the inner cavity of the mounting base. A winding wheel is rotatably installed at the end of the telescopic rod extending out of the mounting base. A winch is mounted at the end of the mounting base, and the winch winds a cable, with the extended section of the cable wrapping around the winding wheel at least one turn.

[0007] As a preferred embodiment of this utility model, the end of the mounting base extends out and connects to the mounting rods at both ends of the winch.

[0008] As a preferred embodiment of this invention, each of the extended sections of the cable is connected to a hook at its bottom.

[0009] As a preferred technical solution of this utility model, the middle part of the positive and negative threaded rod is provided with two limiting ring protrusions that are adapted to the mounting seat.

[0010] As a preferred embodiment of this utility model, the rotating assembly includes: a fixed shaft seat fixedly connected to a horizontal rod, a rotating shaft seat rotatably connected to the fixed shaft seat, the fixed shaft seat having an annular groove coaxial with itself, and a plurality of balls placed in the annular groove, all the balls together supporting the rotating shaft seat, a first gear being sleeved on the rotating shaft seat, the first gear meshing with a second gear, a first motor being embedded in the horizontal rod, and the output end of the first motor being coaxially and fixedly connected to the second gear.

[0011] In a preferred embodiment of this invention, the diameter of the first gear is larger than the diameter of the second gear.

[0012] As a preferred embodiment of this utility model, both the telescopic arm and the horizontal bar are provided with connecting seats, and the two connecting seats are rotatably connected to a hydraulic rod.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. When the two winches have different winding cable lengths, the height of the two ends of the steel structure component can be adjusted to adjust the installation posture of the steel structure component, such as adjusting the tilt installation of the steel structure component, which reduces the construction difficulty of steel structure buildings.

[0015] Second, the worm gear and worm wheel of this application drive two telescopic rods to move closer or further apart through positive and negative threaded rods, thereby adjusting the distance between the two winding wheels to adapt to the hoisting of steel structures of different lengths. Moreover, after the two winding wheels are pulled apart to a certain distance, the hoisted steel structure components are less likely to rotate and their posture is easier to control, making it easier to hoist the steel structure components to the accurate installation position and improving the safety of the hoisting process.

[0027] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0028] Please see Figure 1-5 A steel structure hoisting device includes a telescopic boom 1 extending from the hoisting equipment, with a horizontal bar 2 rotatably connected to the telescopic boom 1. Both the telescopic boom 1 and the horizontal bar 2 are provided with connecting seats 6, and the two connecting seats 6 are rotatably connected to a hydraulic rod 7. The hydraulic rod 7 extends or retracts before use to keep the horizontal bar 2 as horizontal as possible. A rotating assembly 3 is connected to the end of the horizontal bar 2 away from the telescopic boom 1. The output component of the rotating assembly 3 is connected to a mounting base 4, and an extension assembly 5 is mounted on the mounting base 4.

[0029] The rotating assembly 3 includes: a fixed bearing 301 fixedly connected to the horizontal rod 2, and a rotating bearing 302 rotatably connected to the fixed bearing 301. The fixed bearing 301 has an annular groove coaxial with itself, and a plurality of balls 303 are placed in the annular groove. All the balls 303 together lift the rotating bearing 302, reducing the friction between the fixed bearing 301 and the rotating bearing 302. A first gear 304 is sleeved on the rotating bearing 302, and the first gear 304 meshes with a second gear 305. A first motor 306 is embedded in the horizontal rod 2, and the output end of the first motor 306 is coaxially and fixedly connected to the second gear 305.

[0030] The diameter of the first gear 304 is larger than the diameter of the second gear 305, so that the output end of the first motor 306 can amplify the torque to drive the rotating shaft 302 to rotate.

[0031] The extension assembly 5 includes: a threaded rod 501 rotatably mounted in the inner cavity of the mounting base 4, with two limiting annular protrusions in the middle of the threaded rod 501 that fit the mounting base 4. Two vertical plates are rotatably connected to the threaded rod 501 in the inner cavity of the mounting base 4, and the two vertical plates restrict the linear movement of the threaded rod 501 along its own axis via the annular protrusions. A worm gear 502 is coaxially fixedly sleeved in the middle of the threaded rod 501, and the worm gear 502 meshes with a worm 503. A second motor 504 is mounted on the outer wall of the mounting base 4, with its output end coaxially fixedly connected to the worm 503. Telescopic rods 505 are threadedly connected to both ends of the threaded rod 501, and the telescopic rods 505 are slidably connected to the inner cavity of the mounting base 4. A winding wheel 508 is rotatably mounted on the end of the telescopic rod 505 extending out of the mounting base 4, and a winch 506 is mounted on the end of the mounting base 4. The winch 506 winds a cable 507, and the extended section of the cable 507 wraps around the winding reel 508 at least once to prevent the cable 507 from coming off the winding reel 508 during use. Each extended section of the cable 507 is connected to a hook 509 at its bottom, or other components that can be used to fix and connect the steel structure to be hoisted.

[0032] The end of the mounting base 4 extends out and connects to the mounting rods at both ends of the winch 506. The winch 506 is driven by a built-in motor to rotate the outer drum.

[0033] Working principle:

[0034] In use, the lifting equipment controls the telescopic boom 1 to rise and fall. The hydraulic rod 7 extends and retracts with the tilt angle of the telescopic boom 1 to keep the horizontal rod 2 horizontal. Then, hooks 509 are used to hook the two ends of the steel structure component to be lifted. Then, the winch 506 rotates and winds the cable 507 to lift the steel structure component. When the lengths of the two winches 506 and the cable 507 are different, the height of the two ends of the steel structure component can be adjusted to adjust the installation posture. Then, the first motor 306 drives the rotating shaft seat 302 to rotate through the meshing first gear 304 and second gear 305, so that the steel structure component rotates to adjust its posture and align with the installation position.

[0035] While in use, the first motor 306 drives the rotating shaft seat 302 and the mounting seat 4 to rotate together through the first gear 304 and the second gear 305, so as to adjust the installation posture of the steel structure components.

[0036] Before use, the distance between the two winding wheels 508 is adjusted according to the length of the steel structure components. The second motor 504 rotates to drive the worm gear 503 to rotate. The worm gear 503 drives the positive and negative threaded rods 501 to rotate through the worm wheel 502 that meshes with it. The rotating positive and negative threaded rods 501 drive the two telescopic rods 505 to move closer or separate from each other, thereby adjusting the distance between the two winding wheels 508. This adapts to the hoisting of steel structure components of different lengths. Moreover, when the two winding wheels 508 are pulled apart to a certain distance, the hoisted steel structure is less prone to rotation and its posture is easier to control.

[0037] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
