Description

Technical Field

[0001] This utility model relates to the field of building steel structure assembly technology, specifically to an auxiliary assembly tool for steel structure components. Background Technology

[0002] Steel structures are widely used in construction engineering for super high-rise buildings, large factories, stadiums and other fields. With their technical advantages of light weight, high strength, short construction period, environmental protection and recyclability, and excellent seismic resistance, they meet the "dual carbon" goals and the development needs of prefabricated buildings, and have broad development prospects.

[0003] Steel structures are typically assembled on-site using prefabricated technology. The various components of a steel structure are generally fabricated in a factory and then transported to the construction site for assembly. Currently, on-site assembly of steel structures generally utilizes truck cranes for lifting and assembling components. However, truck cranes require significant on-site operating space, making them unsuitable for lifting and assembling steel structure components in confined spaces. This hinders the smooth progress of on-site assembly. Furthermore, truck cranes typically use steel cables for lifting, which have limited lateral restraint capabilities, making them unsuitable for lifting operations in windy conditions. This further impedes the shortening of the steel structure construction cycle. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary assembly tool for steel structure components. Multiple sets of this tool can work together to lift steel structures in a construction site with limited space, ensuring the smooth assembly of steel structures in narrow spaces. By using hooks to clamp the steel structure components, the lateral movement of the steel structure is limited, so that the assembly of steel structure components can be carried out smoothly even in windy conditions, thereby shortening the steel structure assembly construction cycle.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an auxiliary assembly tool for steel structure components, including adjusting columns, connecting beams, and hoisting components. Two adjusting columns are fixedly installed at the left and right ends of the connecting beams. The hoisting components are slidably installed between the two adjusting columns. An auxiliary moving component is installed at the bottom of the adjusting columns. A power component is installed on the connecting beams. The power component provides power for the up and down movement of the hoisting components. The hoisting components include a hoisting box, a hook assembly, and an adjusting component. The hook assembly and the adjusting component are installed on the hoisting box. The hook assembly includes two hooks. The adjusting component is used to drive the two hooks to move closer or further apart.

[0006] Furthermore, the adjusting column includes a hollow column, a base, and an adjusting screw. The hollow column is fixedly installed on the upper part of the base, and the adjusting screw is vertically rotatably installed inside the hollow column. A screw gear is installed on the upper part of the adjusting screw.

[0007] Furthermore, the lower part of the hook is L-shaped and a support plate is provided at the lower part of the hook.

[0008] Furthermore, a grid of reinforcing ribs is provided at the bottom of the hoisting box.

[0009] Furthermore, the auxiliary movement component is disposed at the bottom of the chassis, and the auxiliary movement component includes a plurality of omnidirectional wheels, which are arranged in a matrix at the bottom of the chassis.

[0010] Furthermore, the power assembly includes a drive motor and a fixed base. The drive motor is fixedly mounted on the fixed base, which is located on the upper part of the connecting crossbeam. A transmission sleeve is provided at the output end of the drive motor.

[0011] Furthermore, a power gear is provided inside the connecting crossbeam. The upper part of the rotating support shaft of the power gear is connected to the transmission sleeve by a key transmission method. A coaxial gear set is provided on both the left and right sides of the power gear. The coaxial gear set includes a first reduction gear and a second reduction gear, which are distributed vertically. A third reduction gear is provided on one side of the first reduction gear, and the third reduction gear meshes with the corresponding screw gear.

[0012] Furthermore, the hook assembly also includes transverse guide rails and a transverse drive shaft. An adjustment groove is provided at the bottom of the lifting box. Two transverse guide rails are arranged on the upper sides of the adjustment groove. The transverse drive shaft is rotatably arranged inside the lifting box and located above the adjustment groove. The upper middle part of the two hooks is sleeved on the transverse drive shaft, and the upper sides of the hooks are locked on the corresponding transverse guide rails. The middle part of the two hooks is sleeved in the adjustment groove. A force transmission worm gear is fixedly arranged in the middle of the transverse drive shaft. By rotating the transverse drive shaft, the two hooks can move away from or towards each other.

[0013] Furthermore, the adjustment assembly includes an adjustment rod, a transmission worm gear, and an adjustment wheel. The transmission worm gear is fixedly disposed in the middle of the adjustment rod. The adjustment rod is rotatably disposed in the hoisting box and is distributed in a mutually perpendicular state with the transverse transmission shaft. The transmission worm gear meshes with the force transmission worm wheel. An adjustment wheel is provided at both ends of the adjustment rod, and the adjustment wheel is located on the outside of the hoisting box.

[0014] The beneficial effects of this utility model are: the operation area is small, reducing the requirements for site conditions for lifting rigid structural components; at the same time, the lifting operation cost is low, which helps to reduce the construction cost of steel structure assembly; the two hooks use a rigid clamping method to clamp and lift the rigid structural components, thereby effectively limiting the lateral movement of the rigid structural components and improving the adaptability of the lifting operation environment of the rigid structural components; by using the gear transmission principle, the rotational torque of the adjusting screw is amplified, thereby enabling the smooth lifting of heavier rigid structural components.

Detailed Implementation

[0036] The following will describe specific embodiments and appendices. Figure 1-19The technical solutions in the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0037] This utility model provides an auxiliary assembly tool for steel structure components (such as...). Figure 1 As shown, the system includes adjusting columns 1, connecting beams 2, and lifting components 3. Two adjusting columns 1 are fixedly installed at the left and right ends of the connecting beams 2. The lifting components 3 are slidably installed between the two adjusting columns 1. In practical applications, the height of the adjusting columns 1 determines the lifting height of the rigid structural member 4. Therefore, the height of the adjusting columns 1 can be set based on construction experience during manufacturing. An auxiliary moving component is installed at the bottom of the adjusting columns 1, enabling flexible movement of the adjusting columns 1 on the construction site, thus facilitating rapid positioning and placement. A power component 22 is installed on the connecting beams 2. The power component 22 is the upper... The downward movement provides power, and the hoisting assembly 3 is used to clamp and fix the rigid structural member 4. The hoisting assembly 3 includes a hoisting box 32, a hook assembly 33, and an adjustment assembly 34. The hook assembly 33 and the adjustment assembly 34 are mounted on the hoisting box 32. The two ends of the hoisting box 32 are slidably connected to the corresponding adjustment columns 1, which facilitates the up and down sliding of the entire hoisting assembly 3. The hook assembly 33 includes two hooks 331. The adjustment assembly 34 is used to drive the two hooks 331 to move closer or further apart. In actual application, the two hooks 331 moving closer together clamp and fix the rigid structural member 4, and the two hooks 331 moving further apart release the rigid structural member 4. In practical applications, the construction operation of this utility model occupies a small area, which facilitates hoisting operations in relatively small construction sites, thus enabling the smooth hoisting of steel structure component 4. At the same time, by using two hooks 331 to clamp the ends of the steel structure component 4, the lateral movement of the steel structure component 4 can be effectively limited, thereby improving the adaptability of the hoisting operation environment of the steel structure component 4.

[0038] Based on the above embodiments, the specific implementation of the adjusting column 1 is as follows: The adjusting column 1 includes a hollow column 11, a base 12, and an adjusting screw 13.

Specifically, a column connecting flange 113 is fixedly installed at the bottom of the hollow column 11, and a base bolt hole 122 corresponding to the through hole of the column connecting flange 113 is provided on the upper part of the base 12. The column connecting flange 113 is fixedly connected to the base bolt hole 122 by a plurality of column fixing bolts 115, thereby achieving a fixed connection between the bottom of the hollow column 11 and the base 12. The adjusting screw 13 is rotatably and vertically installed inside the hollow column 11. Specifically, a bearing 52 is provided on the upper part of the base 12, and the bottom of the adjusting screw 13 is sleeved in the bearing 52.

The gear compartment bearing cover plate 114 is provided with through holes corresponding to the gear compartment bearing cover plate bolt holes 116. The gear compartment bearing cover plate 114 is fixed to the upper part of the bearing housing by several bolts, thereby achieving axial positioning of the bearing 51. The top end of the adjusting screw 13 is sleeved in the inner ring of the bearing 51. Therefore, the upper and lower ends of the adjusting screw 13 are supported by the bearing 51 and the bearing 52, so that its stable rotation is achieved. A screw gear 131 is provided at the upper part of the adjusting screw 13. The screw gear 131 is located inside the gear compartment 111. The rotation of the screw gear 131 can drive the rotation of the adjusting screw 13. Furthermore, the specific implementation method for the fixed connection between the connecting beam 2 and the two gear compartments 111 is as follows: a gear compartment connecting flange 1111 is provided on the outside of the gear compartment 111, and a plurality of gear compartment connecting flange bolt holes 1112 are provided on the gear compartment connecting flange 1111. At both ends of the beam box 26 of the connecting beam 2, a connecting beam connecting flange 21 corresponding to the gear compartment connecting flange bolt holes 1112 is provided. A connecting flange bolt hole 211 corresponding to the gear compartment connecting flange bolt holes 1112 is provided on the connecting beam connecting flange 21. By passing a plurality of connecting bolts through the gear compartment connecting flange bolt holes 1112 and the connecting flange bolt holes 211, the connecting beam 2 and the gear compartment 111 are firmly fixed, thereby achieving the fixed connection between the connecting beam 2 and the two hollow columns 11.

[0039] Based on the above embodiments, the specific implementation of the auxiliary moving component is as follows: the auxiliary moving component is disposed at the bottom of the chassis 12, and the auxiliary moving component includes a plurality of universal wheels 121. The plurality of universal wheels 121 are arranged in a matrix at the bottom of the chassis 12. Each universal wheel 121 includes a universal wheel shaft 1211 and a universal wheel body 1212. Two universal wheel bodies 1212 are rotatably disposed at the bottom of the universal wheel shaft 1211. The top end of the universal wheel shaft 1211 is rotatably connected to the bottom of the chassis 12, thereby enabling the universal wheels 121 to turn freely. In this specific embodiment, three rows of universal wheel groups are provided at the bottom of the chassis 12. Each row of universal wheel groups includes seven universal wheels 121. Under light load conditions, the chassis 12 can be moved by manually pushing the adjusting column 1. Under heavy load conditions, the entire chassis 12 can be moved by using an external traction mechanism (such as a tractor head) to pull the adjusting column 1.

[0040] Based on the above embodiments, the specific implementation of the power assembly 22 is as follows: the power assembly 22 includes a drive motor and a fixed base 221. The drive motor is fixedly mounted on the fixed base 221, and the fixed base 221 is located on the upper part of the connecting beam 2. Specifically, a plurality of power assembly fixing bolts 223 are provided on the fixed base 221, and a plurality of fixing base screw holes 233 corresponding to the power assembly fixing bolts 223 are provided on the upper cover plate 23 of the connecting beam 2. The fixing bolt 223 passes through the fixing base screw hole 233 to firmly install the fixing base 221 onto the cover plate 23, thereby achieving a stable installation of the drive motor; several cover plate bolts 231 are provided on the front and rear sides of the cover plate 23, and cover plate screw holes 232 corresponding to the cover plate bolts 231 are provided on the upper part of the front and rear side walls of the connecting box. The cover plate 23 and the connecting box are fastened by screwing the cover plate bolts 231 into the cover plate screw holes 232; the output end of the drive motor faces downward, and a transmission sleeve 222 is provided at the output end of the drive motor.

[0041] Based on the above embodiments, the specific implementation of the internal structure of the connecting beam 2 is as follows: a power gear 24 is provided inside the connecting beam 2. The upper part of the rotating support shaft 241 of the power gear 24 is connected to the transmission sleeve 222 by a key drive. Specifically, a keyway is provided at the upper end of the rotating support shaft 241 and the lower part of the output end of the drive motor. A transmission flat key 2221 is provided on the keyway of the inner sidewall of the transmission sleeve 222. After the transmission sleeve 222 is fitted onto the lower end of the output end of the drive motor and the upper end of the rotating support shaft 241, the transmission flat key 2221 is fitted into the corresponding keyway. A coaxial gear set 27 is provided on both the left and right sides of the power gear 24. The coaxial gear set 27 includes a first reduction gear and a second reduction gear. The first reduction gear and the second reduction gear are distributed vertically, and the power gear 24 meshes with the second reduction gear. A third reduction gear 28 is provided on one side of the first reduction gear. The first reduction gear meshes with the third reduction gear 28, and the third reduction gear 28 meshes with the corresponding screw gear 131. In actual application, in order to make the screw gear 131 have a large rotational torque, the transmission ratio between the third reduction gear 28 and the screw gear 131 is kept constant, thereby ensuring that the speed of the adjusting screw 13 is not too fast. At the same time, the transmission ratio between the first reduction gear and the third reduction gear 28 is appropriately increased so that the third reduction gear 28 has a large torque output, thereby effectively driving the adjusting screw 13 to rise and fall stably. In actual processing, the coaxial gear set 27 and the third reduction gear 28 are both rotatably installed inside the connecting beam 2 using the corresponding gear shaft 25. Specifically, both ends of the gear shaft 25 are fixed to the shaft hole on the side wall of the connecting beam 2 by bearings.

[0042] Based on the above embodiments, the specific implementation method for the vertical sliding connection of the hoisting box 32 between the two adjusting columns 1 is as follows: a connecting rod 35 is respectively provided on the left and right sides of the hoisting box 32, and a connecting sleeve 31 is fixedly provided at the end of the connecting rod 35. The connecting sleeve 31 is sleeved on the corresponding adjusting screw 13 and the transmission is realized through threaded engagement. Through the cooperation relationship of the power gear 24, the second reduction gear, the first reduction gear, the third reduction gear 28 and the screw gear 131, the two adjusting screws 13 are synchronously rotated in the same direction when the power gear 24 rotates, thereby driving the connecting sleeve 31 to rise and fall in the vertical direction, thereby driving the hoisting box 32 to slide smoothly between the two adjusting columns 1. Meanwhile, two vertical slide grooves 321 are respectively provided on the left and right sides of the hoisting box 32, and vertical guide rails 112 matching the vertical slide grooves 321 are provided on the two hollow columns 11. The vertical slide grooves 321 and the vertical guide rails 112 slide in cooperation to ensure that the hoisting box 32 maintains stable vertical operation during the lifting process.

[0043] Based on the above embodiments, the specific implementation of the hook assembly 33 is as follows: The hook assembly 33 further includes a transverse guide rail 333 and a transverse drive shaft 332. An adjustment groove 323 is provided at the bottom of the lifting box 32. Two transverse guide rails 333 are arranged on the upper sides of the adjustment groove 323. The transverse guide rails 333 are fixedly connected to the bottom wall of the lifting box 32. The transverse drive shaft 332 is rotatably arranged inside the lifting box 32 and located above the adjustment groove 323. Specifically, a bearing 53 is symmetrically arranged on the left and right sides inside the lifting box 32. The two ends of the transverse drive shaft 332 are respectively inserted into the bearing 53 to achieve rotational support. The upper middle part of the two hooks 331 is sleeved on the transverse drive shaft 332, and the upper sides of the hooks 331 are locked in the corresponding... Specifically, on the transverse guide rail 333, on both sides of the upper part of the hook 331, there are slots 3312 corresponding to the transverse guide rail 333. The slots 3312 slide with the transverse guide rail 333, thereby realizing the left and right movement guidance of the hook 331 and the front and back swing limit of the hook 331. The transverse transmission shaft 332 is threaded with the upper middle part of the hook 331. Specifically, an adjustment hole 3311 is provided on the upper part of the hook 331. The adjustment hole 3311 is sleeved on the transverse transmission shaft 332 and threaded with the transverse transmission shaft 332. The middle parts of the two hooks 331 are sleeved in the adjustment groove 323. A force transmission worm gear 334 is fixedly installed in the middle of the transverse transmission shaft 332. By rotating the transverse transmission shaft 332, the two hooks 331 can move away from or towards each other.The worm gear 334 drives the transverse transmission shaft 332 to rotate, and the threaded engagement drives the two hooks 331 to move synchronously towards or away from each other along the transverse guide rail 333, realizing flexible adjustment of the distance between the hooks 331. This facilitates the fixed clamping of the steel structure component 4 using the two hooks 331. Furthermore, the specific implementation of the rotation drive of the worm gear 334 using the adjustment assembly 34 is as follows: the adjustment assembly 34 includes an adjustment rod 342, a transmission worm 343, and an adjustment wheel 341. The transmission worm 343 is fixedly installed in the middle of the adjustment rod 342, and the adjustment rod 342 is rotatably installed inside the lifting box 32 and is perpendicular to the transverse transmission shaft 332. The hoisting box 32 is symmetrically equipped with bearings 54 on its front and rear side walls. The two ends of the adjusting rod 342 pass through the bearings 54. The transmission worm 343 meshes with the power transmission worm wheel 334. An adjusting wheel 341 is located at both ends of the adjusting rod 342, and is positioned on the outside of the hoisting box 32. In practical application, the operator rotates the adjusting wheel 341 to drive the transmission worm 343, which in turn drives the power transmission worm wheel 334 to rotate, thus rotating the transverse transmission shaft 332. This ultimately drives the two hooks 331 to move synchronously along the transverse guide rail 333, enabling rapid clamping and positioning of steel structure components 4 of different widths.

[0044] In practical applications, to facilitate the clamping and fixing of the wing plate of the steel structure component 4 using the hook 331, the lower part of the hook 331 is L-shaped and a support plate 3313 is provided at the lower part of the hook 331. Furthermore, to improve the structural support strength of the hoisting box 32, a grid reinforcing rib 322 is provided at the bottom of the hoisting box 32. The grid reinforcing rib 322 will not hinder the sliding movement of the hook 331 along the transverse guide rail 333.

[0045] In the actual processing, in order to facilitate the sealing of the upper part of the hoisting box 32, a detachable sealing plate is set at the upper end of the hoisting box 32. The sealing plate is fixedly connected to the hoisting box 32 by bolts. Specifically, several hoisting box bolts 324 are set at both ends of the sealing plate. The hoisting box bolts 324 pass through the sealing plate and are screwed into the threaded holes at the upper end of the hoisting box 32 to achieve a firm fixation of the sealing plate. Then, the sealing plate is used to achieve the sealing of the upper part of the hoisting box 32.
