Description

Technical Field

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

[0002] Steel structure buildings are structures constructed using structural steel as their load-bearing structure. They typically consist of beams, columns, trusses, and other components made of shaped steel and steel plates, forming the load-bearing structure together with the roof, floors, and walls to create a complete building. Structural steel usually refers to hot-rolled angle steel, channel steel, I-beams, H-beams, and steel pipes. During the construction of steel structure buildings, cranes and other lifting machinery are used with lifting tools to hoist the steel beams. Tools such as balance beams, plate clamps, C-hooks, and slings are generally used. While these tools can meet conventional hoisting needs, they present certain inconveniences and safety hazards due to limitations in adjusting for beam dimensions, the need for specialized lifting tools for each beam size, and insufficiently secure fixing methods between the lifting tools and the beams. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a steel structure hoisting device. This device can meet the fixing requirements of steel structure beams of different lengths, cross-sectional shapes and sizes, and the fixing between the device and the steel structure beam is relatively stable, thus better meeting the hoisting and installation requirements of steel structure beams.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a steel structure hoisting device, comprising a hollow crossbeam, into which a telescopic crossbeam is inserted and installed. An adjustable clamp is installed at the bottom of one end of the telescopic crossbeam. The adjustable clamp includes a transmission connection device fixed to the telescopic crossbeam. A first fixed seat and a second fixed seat are respectively provided on both sides of the transmission connection device. A first rack and a second rack are respectively provided at one end of the first fixed seat and the second fixed seat. The first rack and the second rack are inserted into the interior of the transmission connection device. An L-shaped clamp is connected to the bottom, and a through groove is provided between the two sides of the L-shaped clamp to slide and connect with the lifting clamp. A slide rod and a screw are installed on the top of the lifting clamp. A bidirectional screw mounting seat is fixedly installed inside the hollow crossbeam. A bidirectional screw is rotatably installed on the inner side of the bidirectional screw mounting seat. The bidirectional screw is threadedly connected to the telescopic crossbeam. A first bevel gear is sleeved on the outer side of the bidirectional screw. A fourth rotating shaft is rotatably installed through one side wall of the hollow crossbeam. A second bevel gear is installed at one end of the fourth rotating shaft. The second bevel gear meshes with the first bevel gear.

[0005] The beneficial effects of this utility model are as follows: This device can meet the fixing requirements of steel structure beams of different lengths, cross-sectional shapes and sizes, and the fixing between it and the steel structure beam is relatively stable, thus better meeting the hoisting and installation requirements of the steel structure beam.

[0006] To adjust the spacing between two sets of L-shaped clamps in the same adjustable fixture:

[0007] As a further improvement to the above technical solution: a first rotating shaft and a second rotating shaft are rotatably mounted inside the transmission connection device. A first gear and a worm gear are sleeved on the outer side of the first rotating shaft. A second gear and a third gear are sleeved on the outer side of the second rotating shaft. A third rotating shaft is rotatably mounted inside the transmission connection device. A worm is sleeved on the outer side of the third rotating shaft. The first gear meshes with the second gear. The third gear meshes with the first rack and the second rack. The worm meshes with the worm wheel.

[0008] The beneficial effects of this improvement are as follows: By rotating the handwheel at one end of the third rotating shaft, the worm can be driven to rotate. The worm drives the worm wheel to rotate, which in turn drives the first rotating shaft and the first gear to rotate. At the same time as the first gear rotates, the two sets of second gears meshing with the first gear rotate the rollers simultaneously, thereby driving the two sets of second rotating shafts and the third gear on the outside of the second rotating shafts to rotate. Through the transmission between the third gear and the first rack and the second rack, the first rack and the second rack are driven to move in opposite directions under the guidance of the guide bar and the guide groove, thereby driving the first fixed seat and the second fixed seat to move towards or away from each other, thereby adjusting the distance between the two sets of L-shaped clamps in the same adjustable fixture.

[0009] As a further improvement to the above technical solution: the top and bottom of the first rack and the second rack are provided with guide bars, and the inner side of the transmission connection device is provided with guide grooves, and the guide bars and guide grooves are slidably connected.

[0010] The guide bar and guide groove are slidably connected, which serves to limit the movement between the first rack, the second rack and the transmission connection device, and to provide auxiliary guidance when the first rack and the second rack move.

[0011] As a further improvement to the above technical solution: the slide rod and the screw rod both pass through the first fixed seat and the second fixed seat, the slide rod is slidably connected to the first fixed seat and the second fixed seat, and the screw rod is threadedly connected to the first fixed seat.

[0012] The screw drives the lifting clamp to move up and down through the threaded transmission between it and the first fixed seat, and the slide bar plays a guiding and auxiliary supporting role for the lifting clamp.

[0013] As a further improvement to the above technical solution: the fourth rotating shaft is located at one end outside the hollow crossbeam, the third rotating shaft is located at one end outside the transmission connection device, and the top of the screw is equipped with a handwheel. The outer side of the fourth rotating shaft located outside the hollow crossbeam is threaded and threaded locking sleeve is installed.

[0014] The handwheel is used to facilitate the rotation of the fourth shaft, the third shaft, and the screw. After the threaded locking sleeve is tightened, the fourth shaft can be locked so that it cannot be rotated.

[0015] For the hoisting of this device:

[0016] As a further improvement to the above technical solution: a steel cable connector is installed on the top of the hollow beam, a steel cable is connected to the top of the steel cable connector, a hook connector is connected to the top of the steel cable, and a lifting ring is connected to the top of the hook connector.

[0017] The beneficial effect of this improvement is that after connecting the lifting ring to the hook of the hoisting machinery, the device can be lifted together with the steel structure.

[0018] For the synchronous lifting and lowering adjustment of the two sets of price-increasing clamps:

[0019] As a further improvement to the above technical solution: one end of one of the lifting clamps is provided with a telescopic connecting plate, and the telescopic connecting plate is inserted and connected to the other lifting clamp.

[0020] The beneficial effects of this improvement are: the telescopic connecting plate allows the two sets of lifting clamps to rise and fall synchronously, so a single screw can be used to adjust the synchronous rise and fall of the two sets of lifting clamps.

[0021] To improve the clamping stability of the steel structure beam:

[0022] As a further improvement to the above technical solution: the bottom of the lifting clamp and the inner bottom surface of the L-shaped clamp are both provided with anti-slip rubber pads.

[0023] The beneficial effects of this improvement are: the anti-slip rubber pad increases the friction between the L-shaped clamp, the lifting clamp, and the steel structure beam, thereby further improving clamping stability.

[0024] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0033] like Figure 1-6As shown, a steel structure hoisting tool includes a hollow crossbeam 1, into which a telescopic crossbeam 2 is inserted. An adjustable clamp is installed at the bottom of one end of the telescopic crossbeam 2. The adjustable clamp includes a transmission connection device 3 fixed to the telescopic crossbeam 2. A first fixed seat 12 and a second fixed seat 13 are respectively provided on both sides of the transmission connection device 3. A first rack 14 and a second rack 15 are respectively provided at one end of the first fixed seat 12 and the second fixed seat 13. The first rack 14 and the second rack 15 are inserted into the interior of the transmission connection device 3. An L-shaped clamp 18 is connected to the bottom of the first fixed seat 12 and the second fixed seat 13. A through groove 19 is provided between the two sides of the clamping plate 18 and is slidably connected to the lifting clamping plate 20. A sliding rod 22 and a screw 23 are installed on the top of the lifting clamping plate 20. A bidirectional screw mounting seat 31 is fixedly installed inside the hollow crossbeam 1. A bidirectional screw 32 is rotatably installed on the inner side of the bidirectional screw mounting seat 31. The bidirectional screw 32 is threadedly connected to the telescopic crossbeam 2. A first bevel gear 33 is sleeved on the outer side of the bidirectional screw 32. A fourth rotating shaft 34 is rotatably installed through one side wall of the hollow crossbeam 1. A second bevel gear 35 is installed at one end of the fourth rotating shaft 34. The second bevel gear 35 meshes with the first bevel gear 33.

[0034] This device can meet the fixing requirements of steel structure beams of different lengths, cross-sectional shapes and sizes. The fixing between the device and the steel structure beam is relatively stable, which better meets the hoisting and installation requirements of the steel structure beam.

[0035] The transmission connection device 3 has a first rotating shaft 4 and a second rotating shaft 7 rotatably mounted inside. A first gear 5 and a worm gear 6 are sleeved on the outer side of the first rotating shaft 4. A second gear 8 and a third gear 9 are sleeved on the outer side of the second rotating shaft 7. A third rotating shaft 10 is rotatably mounted inside the transmission connection device 3. A worm 11 is sleeved on the outer side of the third rotating shaft 10. The first gear 5 meshes with the second gear 8. The third gear 9 meshes with the first rack 14 and the second rack 15. The worm 11 meshes with the worm gear 6.

[0036] By rotating the handwheel 24 at one end of the third rotating shaft 10, the worm gear 11 can be driven to rotate. The worm gear 11 drives the worm wheel 6 to rotate, which in turn drives the first rotating shaft 4 together with the first gear 5 to rotate. At the same time as the first gear 5 rotates, the two sets of second gears 8 meshing with the first gear 5 rotate the rollers simultaneously, thereby driving the two sets of second rotating shafts 7 together with the third gear 9 on the outside of the second rotating shaft 7 to rotate. Through the transmission between the third gear 9 and the first rack 14 and the second rack 15, the first rack 14 and the second rack 15 are driven to move in opposite directions under the guidance of the guide bar 16 and the guide groove 17, thereby driving the first fixed seat 12 and the second fixed seat 13 to move towards or away from each other, thereby adjusting the distance between the two sets of L-shaped clamps 18 in the same set of adjustable clamps.

[0037] The first rack 14 and the second rack 15 are provided with guide bars 16 at the top and bottom, and the inner side of the transmission connection device 3 is provided with a guide groove 17. The guide bars 16 and the guide groove 17 are slidably connected.

[0038] The guide bar 16 and the guide groove 17 are slidably connected, which serves to limit the movement between the first rack 14, the second rack 15 and the transmission connection device 3, and to provide auxiliary guidance when the first rack 14 and the second rack 15 move.

[0039] The slide rod 22 and the screw rod 23 both pass through the first fixed seat 12 and the second fixed seat 13. The slide rod 22 is slidably connected to the first fixed seat 12 and the second fixed seat 13, and the screw rod 23 is threadedly connected to the first fixed seat 12.

[0040] The screw 23 drives the lifting clamp 20 to rise and fall through the threaded transmission between it and the first fixed seat 12, and the slide bar 22 plays a guiding and auxiliary supporting role for the lifting clamp 20.

[0041] The fourth rotating shaft 34 is located at one end outside the hollow crossbeam 1, the third rotating shaft 10 is located at one end outside the transmission connection device 3, and the top of the screw 23 are all equipped with handwheels 24. The outer side of the fourth rotating shaft 34 located outside the hollow crossbeam 1 is threaded and threaded locking sleeve 25 is threadedly installed.

[0042] The handwheel 24 is used to facilitate the rotation of the fourth shaft 34, the third shaft 10 and the screw 23. After the threaded locking sleeve 25 is tightened, the fourth shaft 34 can be locked so that it cannot be rotated.

[0043] A steel cable connector 27 is installed on the top of the hollow crossbeam 1. A steel cable 28 is connected to the top of the steel cable connector 27. A hook connector 29 is connected to the top of the steel cable 28. A lifting ring 30 is connected to the top of the hook connector 29.

[0044] After connecting the lifting ring 30 to the hook of the hoisting machinery, the device can be lifted together with the steel structure.

[0045] One end of one of the lifting clamps 20 is provided with a telescopic connecting plate 21, and the telescopic connecting plate 21 is inserted and connected to the other lifting clamp 20.

[0046] The telescopic connecting plate 21 enables the two sets of lifting clamps 20 to rise and fall synchronously. Thus, a single screw 23 is sufficient to achieve synchronous lifting and lowering adjustment of the two sets of lifting clamps.

[0047] The bottom of the lifting clamp 20 and the inner bottom surface of the L-shaped clamp 18 are both provided with anti-slip rubber pads 26.

[0048] The anti-slip rubber pad 26 increases the friction between the L-shaped clamping plate 18, the lifting clamping plate 20 and the steel structure beam, thereby further improving the clamping stability.

[0049] The working principle and usage process of this utility model: When using this device, the extension length of the telescopic beam 2 is adjusted according to the length of the steel structure beam to be hoisted. During adjustment, loosening the threaded locking sleeve 25 allows the handwheel 24 to rotate the fourth rotating shaft 34, driving the second bevel gear 35 to drive the first bevel gear 33 and the double-acting screw 32 to rotate. This, through the transmission between the double-acting screw 32 and the telescopic beam 2, drives the two sets of telescopic beams 2 to move synchronously in opposite directions or towards each other, thereby adjusting the distance between the two sets of adjustable clamps to meet the clamping and fixing needs of steel structure beams of different lengths. After completing this adjustment, the threaded locking sleeve 25 can be tightened again to adjust the fourth rotating shaft 34. Locking is performed to maintain a stable and fixed distance between the two sets of adjustable clamps. During the hoisting of steel beams, the adjustable clamps can be adjusted according to the cross-sectional shape of the beam. During adjustment, rotating the handwheel 24 at one end of the third rotating shaft 10 drives the worm gear 11 to rotate. The worm gear 11 drives the worm wheel 6 to rotate, which in turn drives the first rotating shaft 4 along with the first gear 5 to rotate. Simultaneously, the two sets of second gears 8 meshing with the first gear 5 rotate, thereby driving the two sets of second rotating shafts 7 along with the third gear 9 on the outer side of the second rotating shaft 7 to rotate. Through the transmission between the third gear 9 and the first rack 14 and the second rack 15, the first rack is driven... 14. The second rack 15 moves in opposite directions under the guidance of the guide bar 16 and the guide groove 17, thereby driving the first fixed seat 12 and the second fixed seat 13 to move towards or away from each other. This adjusts the distance between the two sets of L-shaped clamping plates 18 in the same adjustable fixture, meeting the clamping needs of steel beams with different cross-sectional widths. By rotating the handwheel 24 at the top of the worm gear 11, the two sets of lifting clamping plates 20 can be driven to move synchronously under the sliding guide of the slide rod 22 and the first fixed seat 12 and the second fixed seat 13, thereby adjusting the distance between the bottom plate of the L-shaped clamping plate 18 and the lifting clamping plate 20, meeting the clamping needs of steel beams with different cross-sectional heights. This is useful when hoisting steel structure beams. Using L-shaped clamps 18 and lifting clamps 20, the outer ends of the steel beam structure are securely clamped from all directions. Anti-slip pads 26 increase the friction between the L-shaped clamps 18, lifting clamps 20, and the steel beam, further improving clamping stability. After connecting the lifting rings 30 to the hooks of the hoisting machinery, the device can be lifted together with the steel structure. After the steel beam is hoisted and placed in the installation position, the device can be released from fixing the steel beam. In summary, this device can meet the fixing requirements of steel beams of different lengths, cross-sectional shapes, and sizes, and the fixing between the device and the steel beam is relatively stable, better meeting the hoisting and installation requirements of steel beams.
