Description

Technical Field

[0001] This invention relates to the field of steel beam hoisting for steel structure factory roofs, specifically a hoisting and positioning device for steel beams on the roofs of steel structure factory buildings. Background Technology

[0002] Steel structure factory buildings are factory buildings that use steel as the main structural material. They can withstand large spans and heavy loads, providing better structural stability. Steel structure factory buildings are mainly composed of multiple sets of steel columns and steel beams. (See also...) Figure 9 When constructing a steel structure workshop, steel columns are vertically installed to their corresponding positions, and steel beams are symmetrically installed to their corresponding positions on the steel columns. After installation, there is a certain angle between the steel beams and steel columns, thus completing the installation of the steel beams and steel columns.

[0003] The current method for installing steel beams and columns involves placing the steel columns in their corresponding positions, suspending the steel beams using a crane, manually adjusting the angle between the steel beams and columns, and finally securing the steel beams to the columns with bolts, thus completing the installation of the steel beams and columns.

[0004] The following problems exist in the current installation of steel beams and columns: The angle between the steel beams and columns needs to be manually adjusted, posing a certain safety risk; the steel beams may tilt in the front-to-back direction when installed onto the columns, resulting in the beams and columns not being on the same horizontal plane after installation, thus reducing the quality of the completed steel structure building; and the need for manual alignment and installation of the beams and columns reduces installation efficiency.

A positioning device is slidably installed in the square grooves. The positioning device is fixedly installed at the lower end of the U-shaped plate.

[0008] The positioning device includes a sleeve slidably installed in a square groove, a push column with an elastic telescopic structure slidably installed inside the sleeve, and a plurality of vertically arranged flat plates provided at the end of the push column away from the sleeve. Guide grooves are symmetrically opened at the front and rear ends of the upper side of the middle of the U-shaped plate. A guide slider is fixedly installed at the lower end of the push column and is slidably installed in the guide groove. The positioning device also includes a hydraulic cylinder fixedly installed at the lower end of the U-shaped plate. An L-shaped rod is installed at the lower end of the sleeve, and the opposite sides of the L-shaped rod are jointly installed on the telescopic end of the hydraulic cylinder.

[0009] Preferably, the clamping unit includes multiple vertically arranged clamping plates disposed at the front end of the adjusting rod, wherein the middle clamping plate is fixedly installed at the front end of the adjusting rod, and the upper and lower clamping plates are jointly installed with a clamping screw through a threaded connection, and the middle clamping plate and the middle clamping screw are rotatably installed, and locking pins are installed at both the upper and lower ends of the middle clamping plate, and the locking pins are slidably connected to their corresponding clamping plates, and multiple fastening teeth are evenly installed on the side of the clamping plates that are close to each other.

[0010] Preferably, a square rod is installed at the end of the L-shaped rod away from the connecting rod, and a mating plate is installed at the end of the square rod away from the L-shaped rod.

[0011] Preferably, the mating plate has an inclined surface at one end near the L-shaped rod.

[0012] Preferably, the front and rear side walls of the U-shaped plate are slidably equipped with limiting posts with elastic telescopic structures. The ends of the limiting posts that are far apart from each other are set as inclined surfaces that cooperate with the inclined surfaces of the near-L-shaped rods, and the ends of the limiting posts that are close to each other are provided with multiple limiting plates.

[0013] Preferably, the plurality of limiting plates are arranged vertically, wherein the lower limiting plate and the limiting post are fixedly installed, the upper limiting plate is fitted with a limiting bolt by means of thread engagement, and the lower end of the limiting bolt is rotatably installed with the lower limiting plate.

[0016] The beneficial effects of the present invention are as follows: 1. The present invention uses a clamping device to centrally clamp the steel column, which facilitates the positioning of the steel beam and the steel column. The clamping device can clamp steel columns of different specifications at multiple ends, thereby enabling the steel column to be stably and vertically installed in the corresponding installation position. At the same time, a synchronization device is set to support the steel beam, and the synchronization device can drive the steel beam to rotate, thereby adjusting the angle between the steel beam and the steel column, increasing the applicability of the present invention.

[0017] 2. This invention uses a positioning device to clamp and smooth the steel beam, preventing it from slipping out of the synchronization device. Simultaneously, when installing the steel beam onto the steel column, the positioning device can smooth the beam at multiple ends, increasing the smoothing effect and preventing tilting in the front-to-back direction. This ensures that the installed steel beam and steel column are on the same horizontal plane, increasing the quality of the completed steel structure workshop. After smoothing the steel beam, the positioning device aligns the middle of the steel beam and steel column, and moves the steel beam towards the steel column to the corresponding installation position, facilitating installation and increasing the efficiency of steel beam and steel column installation.

[0018] 3. This invention limits the smoothed steel beam by setting a limiting plate, preventing the steel beam from tilting in the front-to-back direction when it is moved towards the steel column, thereby further increasing the quality of the steel structure workshop after construction.

[0030] The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where no specific technology or conditions are specified in the embodiments, they shall be performed in accordance with the technology or conditions described in the literature in the field or in accordance with the product manual.

[0031] See Figure 1 A steel structure factory roof steel beam hoisting and positioning device includes a clamping device 1, a synchronization device 2 installed above the clamping device 1, and a positioning device 3 installed inside the synchronization device 2.

[0032] This invention can clamp steel beams and columns of different sizes, thus increasing its applicability. It can also flatten the clamped steel beams to prevent them from tilting forward or backward, enabling precise and stable installation of the beams and columns, increasing the stability of the assembled steel structure workshop. Furthermore, it aligns the center of the steel beams and columns, increasing installation efficiency. Specifically, clamping device 1 clamps the steel column, and by controlling clamping device 1, it moves the clamped steel column to the installation position. Synchronization device 2 clamps the steel beam, and synchronization device 2 can... The clamped steel beam is rotated, and the angle between the steel beam held by the synchronous device 2 and the steel column held by the clamping device 1 is changed according to the specifications of the steel structure workshop to be built. After the synchronous device 2 is adjusted, the positioning device 3 can smooth the clamped steel beam and align the middle of the smoothed steel beam and the steel column. Then, the steel beam is moved to the corresponding installation position of the steel column to complete the installation. The clamping device 1 releases the installed steel column, and the synchronous device 2 releases the installed steel beam. The above steps are repeated to continuously install steel columns and steel beams to complete the construction of the steel structure workshop.

[0033] See Figures 1-3 The clamping device 1 includes a U-shaped base 11, with a fixing plate 16 symmetrically installed at the rear end of the base 11. Rollers 12 are evenly installed at the lower end of the base 11. Adjustment grooves 13 are symmetrically opened at the rear end of the inner side of the base 11. Adjustment rods 14 are slidably installed in the adjustment grooves 13. A clamping unit 15 is installed at the front end of the adjustment rods 14. A bidirectional lead screw 17 is installed at the rear end of the adjustment rods 14 through a threaded connection, and the bidirectional lead screw 17 is rotatably connected to the fixing plate 16.

[0034] The clamping unit 15 includes a plurality of vertically arranged clamping plates 151 disposed at the front end of the adjusting rod 14. The middle clamping plate 151 is fixedly installed at the front end of the adjusting rod 14. The upper and lower clamping plates 151 are connected together by a threaded connection to a clamping screw 152. The middle clamping plate 151 and the middle clamping screw 152 are rotatably installed. Locking pins 154 are installed at both the upper and lower ends of the middle clamping plate 151. The locking pins 154 and their corresponding clamping plates 151 are slidably connected. A plurality of fastening teeth 153 are evenly installed on the side of the clamping plates 151 that are close to each other.

[0035] The clamping device 1 is used to clamp steel columns of different specifications and can move the clamped steel columns to the corresponding installation positions, thereby enabling continuous installation of steel columns. The clamping unit 15 can clamp steel columns of different sizes from multiple ends, increasing the stability of the clamped steel columns. Specifically, the steel column to be installed is placed in the groove of the U-shaped base 11, and the clamping screw 152 is turned. The clamping screw 152 drives the upper and lower clamping plates 151 to move synchronously away from the middle clamping plate 151, thereby adjusting the spacing between the clamping plates 151 according to the specifications of the steel column. The locking pin 154 can lock the upper and lower clamping plates 151 in direction to prevent rotation. Turning the bidirectional screw 17 controls the adjusting rod 14 to move synchronously inward, and the adjusting rod 14 drives the clamping plates 151 to clamp the steel column. The clamping mechanism utilizes fastening teeth 153 on clamping plates 151 to increase friction between the clamping plates 151 and the steel column, further enhancing stability during clamping. Multiple clamping plates 151 provide multi-end clamping of the steel column, further increasing stability. Rollers 12 are installed at the lower end of the base 11, enabling the base 11 to move the clamped steel column to the corresponding installation position. After a set of steel columns and beams is installed, the double-acting screw 17 is turned to move the adjusting rod 14 synchronously in the same direction. The adjusting rod 14 moves the clamping plates 151 synchronously, releasing the installed steel column and placing a new steel column into the groove of the base 11. Tightening the double-acting screw 17 then clamps the steel column with the clamping plates 151, pushing the base 11 to move the clamped steel column to the installation position, thus enabling continuous installation of steel columns.

[0036] See Figure 2 and Figure 4 Hydraulic rods 111 are symmetrically installed on the upper end of the base 11. The synchronization device 2 includes a U-shaped support plate 21 with the upper end of the hydraulic rods 111 installed together. Connecting rods 22 are symmetrically installed on the left and right sides of the upper end of the support plate 21. An electric push rod 23 is installed in the middle of the upper end of the support plate 21. A U-shaped synchronization rod 24 is installed on the upper end of the electric push rod 23. The upper end of the connecting rod 22 and the upper end of the synchronization rod 24 near the connecting rod 22 are hinged to a U-shaped plate 25. The hinge of the synchronization rod 24 and the U-shaped plate 25 is slidably installed. Square grooves 26 are symmetrically opened at the front and rear ends of the U-shaped plate 25. A positioning device 3 is slidably installed in the square grooves 26. The positioning device 3 is fixedly installed at the lower end of the U-shaped plate 25.

[0037] The synchronization device 2 is used to support the steel beam and drive the supported steel beam to rotate, thereby adjusting the angle of the supported steel beam according to the specifications of the steel structure workshop to be built, increasing the applicability of the invention; the steel beam is placed in the U-shaped plate 25 and the hydraulic rod 111 is activated to drive the support plate 21 to move upward, so that the steel beam supported by the U-shaped plate 25 moves upward to the corresponding installation position. The electric push rod 23 is activated to push the synchronization rod 24 upward, and the synchronization rod 24 pushes the U-shaped plate 25 upward. The synchronization rod 24 and the U-shaped plate 25 are slidably installed at the hinge joint, so that the U-shaped plate 25 can rotate with the hinge joint of the U-shaped plate 25 and the connecting rod 22 as the reference under the action of the connecting rod 22 at the lower end. This allows the angle of the steel beam held by the U-shaped plate 25 to be adjusted, so that the steel beam can be installed at a suitable tilt angle on the upper end of the steel column according to the specifications of the steel structure workshop to be built.

[0038] See Figure 4 , Figure 5 and Figure 7 The positioning device 3 includes a sleeve 31 slidably installed in a square groove 26. A pusher 32 with an elastic telescopic structure is slidably installed inside the sleeve 31. Multiple flat plates 33 are provided at the end of the pusher 32 away from the sleeve 31. Guide grooves 255 are symmetrically opened at both ends of the upper middle part of the U-shaped plate 25. A guide slider 321 is fixedly installed at the lower end of the pusher 32, and the guide slider 321 is slidably installed in the guide groove 255. The positioning device 3 also includes a hydraulic cylinder 34 fixedly installed at the lower end of the U-shaped plate 25. The lower end of the sleeve 31 is equipped with... There is an L-shaped rod 35, and the opposite sides of the L-shaped rod 35 are jointly installed on the telescopic end of the hydraulic cylinder 34; multiple flat plates 33 are arranged vertically, and the lower flat plate 33 and the push column 32 are fixedly installed. The upper flat plate 33 is equipped with an adjusting bolt 331 by means of thread engagement, and the lower end of the adjusting bolt 331 is rotatably installed with the lower flat plate 33. The upper end of the upper flat plate 33 is set as an inclined surface, and the upper end of the lower flat plate 33 is fixedly installed with a limit block 332, and the limit block 332 is slidably connected to the upper flat plate 33.

[0039] The positioning device 3 can clamp the steel beam supported by the U-shaped plate 25, thereby enabling the steel beam to be stably placed inside the U-shaped plate 25. The positioning device 3 can also smooth the steel beam to prevent it from tilting forward or backward. This ensures that the steel beam and steel column are on the same horizontal plane when the steel beam is installed onto the steel column, increasing the quality of the completed steel structure workshop. At the same time, the positioning device 3 can also align the middle of the clamped steel beam and steel column, thereby facilitating the installation of the steel beam and steel column and increasing the installation efficiency.

[0040] Specifically, when the steel beam is placed into the U-shaped plate 25, the smoothing plate 33, under the elastic structure of the push column 32, adheres to the front and rear sides of the steel beam. The inclined surface of the upper smoothing plate 33 facilitates the placement of the steel beam into the U-shaped plate 25. The hydraulic cylinder 34 is activated to push the L-shaped rod 35 towards the steel column. The L-shaped rod 35 drives the sleeve 31 to move along the square groove 26. The sleeve 31, through the push column 32, drives the smoothing plate 33 to move. The push column 32, under the action of the guide slider 321, moves along the guide groove 255, thus allowing the smoothing plate 33 to first smooth the steel beam. Furthermore, by turning the adjusting bolt 331, the upper smoothing plate 33 moves upward, thereby adjusting the spacing between the smoothing plates 33, enabling the smoothing of steel beams of different specifications. Multi-end smoothing enhances the smoothing effect on the steel beam. Simultaneously, the limiting block 332 can limit the upper smoothing plate 33 to prevent it from rotating. After the steel beam is smoothed, the guide slider 321 can move along the guide groove 255 towards each other, thereby driving the smoothing plate 33 to move towards the steel beam via the push column 32, aligning the middle of the steel beam and the steel column. The push column 32 is an elastic telescopic structure, which allows the smoothing plate 33 to move the steel beam to the installation position with the steel column and complete the installation. After the steel beam is installed, the hydraulic cylinder 34 drives the L-shaped rod 35 to retract, thereby driving the push column 32 and the smoothing plate 33 back to their initial state via the sleeve 31, facilitating the installation of the next set of steel beams.

[0041] See Figure 5 , Figure 6 and Figure 8 A square rod 36 is installed at the end of the L-shaped rod 35 away from the connecting rod 22. A mating plate 37 is installed at the end of the square rod 36 away from the L-shaped rod 35. The mating plate 37 has an inclined surface at the end near the L-shaped rod 35. Limiting posts 251 with elastic telescopic structures are slidably installed on the front and rear side walls of the U-shaped plate 25. The ends of the limiting posts 251 that are far apart are set as inclined surfaces that mate with the inclined surface near the L-shaped rod 35. Multiple limiting plates 252 are provided at the ends of the limiting posts 251 that are close to each other. Multiple limiting plates 252 are evenly installed vertically at the end. The lower limiting plate 252 and the limiting post 251 are fixedly installed. The upper limiting plate 252 is fitted with a limiting bolt 253 by means of thread engagement. The lower end of the limiting bolt 253 is rotatably installed with the lower limiting plate 252. A locking block 256 is fixedly installed on the upper end of the lower limiting plate 252 and is slidably connected to the upper limiting plate 252. Multiple rollers 254 are evenly installed on the side of the limiting plate 252 corresponding to the middle part of the U-shaped plate 25.

[0042] When the hydraulic cylinder 34 is activated, pushing the L-shaped rod 35 towards the steel column, the L-shaped rod 35 drives the mating plate 37 to move via the square rod 36. The inclined surface of the mating plate 37 can engage with the inclined surface of the limiting post 251, causing the limiting post 251 to move towards the steel beam. Under its own elasticity, the limiting post 251 causes the limiting plate 252 to fit against the front and rear sides of the steel beam. Consequently, when the smoothing plate 33 moves the steel beam towards the steel column, the mating plate 37 can limit the steel beam, preventing the smoothed steel beam from tilting forward or backward again. Furthermore, by tightening the limiting bolt 2... 53 can control the upper and lower limit plates 252 to move synchronously away from the middle limit plate 252, thereby adjusting the distance between the limit plates 252, so that the limit plates 252 can limit the steel beams of different specifications at multiple ends, increasing the limiting effect on the steel beams. The locking block 256 can limit the upper limit plate 252 to prevent the upper limit plate 252 from rotating. The rollers 254 set at the section where the limit plates 252 are close to each other can reduce the friction between the steel beam and the limit plates 252, so that the smooth plate 33 can drive the steel beam to the installation position more smoothly.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
