Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0019] Example 1

[0020] like Figure 1-3 As shown, this is the first embodiment of the present invention. This embodiment provides a steel hoisting device for construction engineering, including a mobile base 1. A support assembly 2, a lifting assembly 3, and a rotating assembly 4 are installed on the top of the mobile base 1. The support assembly 2 and the lifting assembly 3 are used for hoisting steel, and the rotating assembly 4 is used for adjusting the direction. The support assembly 2 is fixed to the top of the rotating assembly 4, the lifting assembly 3 is installed on the surface of the support assembly 2, and the rotating assembly 4 is fixed to the top of the mobile base 1. The rotating assembly 4 includes a support column 401, a support plate 402, a fixed gear 403, a rotating gear 404, and a servo motor 405. The fixed gear 403 is fixed to the top of the support column 401. The support plate 402 is movably connected to the fixed gear 403 through a bearing. The rotating gear 404 meshes with the fixed gear 403. The servo motor 405 is fixed to the top of the support plate 402, and the output shaft of the servo motor 405 passes through the support plate 402 and is connected to the rotating gear 404 for transmission.

[0021] like Figure 1-3As shown, the servo motor 405 is fixed to the top of the support plate 402, and its output shaft passes through the support plate 402 and is connected to the rotating gear 404. The rotating gear 404 meshes with the fixed gear 403. When the servo motor 405 starts, it will drive the rotating gear 404 to rotate. Due to the meshing relationship between the rotating gear 404 and the fixed gear 403, the support plate 402 rotates around the support column 401. The support assembly 2 is fixed to the top of the support plate 402 of the rotating assembly 4, and the lifting assembly 3 is installed on the surface of the support assembly 2. This allows the rotation of the support plate 402 to drive the support assembly 2 and the lifting assembly 3 to rotate as a whole, which facilitates the adjustment of the lifting direction and solves the problem of difficulty in adjusting the lifting direction due to the inconvenience of the boom rotation. This provides convenience for steel lifting operations. The support plate 402 and the fixed gear 403 are connected by bearings, which can greatly reduce the rotational friction. The servo motor 405 is used for gear meshing transmission, and 360° precise positioning is achieved through closed-loop control.

[0022] Example 2

[0023] Reference Figure 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0024] In this embodiment, the movable base 1 includes a support base 101, a caster wheel 102 and a handle 103. The support column 401 is fixedly connected to the support base 101, the handle 103 is fixed to the top of the support base 101, and the caster wheel 102 is installed at the bottom of the support base 101.

[0025] The support assembly 2 includes a column 201, a first cantilever 202, a second cantilever 203, a connecting plate 204, a first hydraulic cylinder 205, and a second hydraulic cylinder 206. The column 201 is fixed to the top of the support plate 402. One end of the second cantilever 203 extends into the inner cavity of the first cantilever 202 and is slidably connected to the inner cavity of the first cantilever 202.

[0026] One end of the connecting plate 204 is fixedly connected to the first cantilever 202, and the other end of the connecting plate 204 is movably connected to the column 201 via a movable pin. One end of the first hydraulic cylinder 205 is movably connected to the column 201 via a movable pin, and the output end of the first hydraulic cylinder 205 is movably connected to the connecting plate 204 via a movable pin. One end of the second hydraulic cylinder 206 is movably connected to the first cantilever 202 via a movable pin, and the output end of the second hydraulic cylinder 206 is movably connected to the second cantilever 203 via a movable pin.

[0027] The lifting assembly 3 includes an electric hoist 301, a rope 302, a pulley 303, a hook 304, and a permanent magnet lifting device 305. The pulley 303 is fixed to one end of the second cantilever 203 located outside the first cantilever 202, and the electric hoist 301 is fixed to the top of the first cantilever 202.

[0028] The rope 302 is wound around the surface of the electric hoist 301. The permanent magnet lifting device 305 is movably connected to the hook 304. One end of the rope 302 passes through the pulley 303 and is fixedly connected to the hook 304.

[0029] like Figure 1-3 As shown, the mobile base 1 includes a support base 101, casters 102, and a handle 103. The casters 102 are installed at the bottom of the support base 101. By pushing the handle 103, the entire hoisting equipment can be flexibly moved to a suitable position in a construction site with limited internal space. This not only assists in adjusting the hoisting direction but also allows for steel hoisting at different positions, further improving the equipment's operational flexibility in limited spaces. The support assembly 2 includes a column 201, a first cantilever 202, a second cantilever 203, a connecting plate 204, a first hydraulic cylinder 205, and a second hydraulic cylinder 206. The lifting assembly 3 includes an electric hoist 301, a rope 302, a pulley 303, a hook 304, and a permanent magnet lifting device 305. Hydraulic cylinder 205 and hydraulic cylinder 206 can adjust the position and angle of the first cantilever 202 and the second cantilever 203. The second cantilever 203 slides in the inner cavity of the first cantilever 202 through the extension and retraction of the second hydraulic cylinder 206 to achieve radius adjustment. The first hydraulic cylinder 205 drives the connecting plate 204, causing the first cantilever 202 to rotate around the hinge point of the column 201 to achieve pitch angle adjustment. The electric hoist 301 lifts and lowers the steel through the rope 302, pulley 303 and hook 304. It works in conjunction with the rotating component 4. After the rotating component 4 adjusts its direction, the support component 2 and the lifting component 3 can quickly carry out the steel lifting operation, improving the lifting efficiency and better adapting to the construction environment with limited internal space.

[0030] In use, the support base 101 serves as the basic support structure for the entire equipment. The casters 102 installed at the bottom allow the equipment to flexibly change its direction of movement. Operators can move the equipment to the required position for steel hoisting operations by holding the handle 103 on top of the support base 101 and pushing or pulling it. The first hydraulic cylinder 205 and the second hydraulic cylinder 206 are used to adjust the angle and length of the cantilever. One end of the first hydraulic cylinder 205 is movably connected to the column 201, and the output end is connected to the connecting plate 204. Its extension and retraction can change the angle of the first cantilever 202 relative to the column 201. The second hydraulic cylinder 206 connects the first cantilever 202 and the second cantilever 203; its extension and retraction can control the extension and retraction of the second cantilever 203 relative to the first cantilever. The sliding mechanism within 202 allows for adjustment of the cantilever length. When steel needs to be lifted, the operator controls the electric hoist 301 to rotate, lowering the rope 302 and moving the permanent magnet lifting device 305 above the steel. The permanent magnet lifting device 305 uses magnetic force to attract the steel, and then the electric hoist 301 rotates in the opposite direction, retracting the rope 302 and lifting the steel. When the lifting direction needs to be adjusted, the servo motor 405 is started, driving the rotating gear 404 to rotate. Since the rotating gear 404 meshes with the fixed gear 403, the rotating gear 404 will roll along the fixed gear 403, thereby driving the support plate 402 to rotate. The support assembly 2 and lifting assembly 3 installed on the support plate 402 also rotate accordingly, realizing the adjustment of the lifting direction.
