Specific implementation mode

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Refer to Figures 1-5, an embodiment provided by the present utility model: It includes a base 1, a pulley group housing 19, and a steel cable 28. A load-bearing plate 2 is fixedly connected to the upper end of the base 1. Support frames 3 are fixedly connected to both the front and rear sides of the load-bearing plate 2. A connecting plate 4 is fixedly connected to the upper end of the support frame 3; a second pulley groove 14 is opened at the front end of the support frame 3, guide rail grooves 13 are opened on both the left and right sides of the support frame 3, a caliper groove 12 is opened at the rear side of the support frame 3, a caliper 11 is fixedly connected in the caliper groove 12, a first wire guide wheel 10 is rotatably connected to the bottom of the support frame 3, grooves 24 are opened in the middle of both the left and right sides of the load-bearing plate 2, steel cable grooves 6 are opened through the front and rear sides of the load-bearing plate 2, first pulley grooves 5 are opened through the left and right sides of both the front and rear sides of the load-bearing plate 2, the middle of the lower end of the pulley group housing 19 is rotatably connected to a fourth rotating shaft 18, a runner 20 is fixedly connected to the outer wall of the fourth rotating shaft 18, a rubber sleeve 21 is fixedly connected to the outer wall of the middle of the runner 20, the upper end of the pulley group housing 19 is rotatably connected to a second rotating shaft 16, the middle rear side of the pulley group housing 19 is rotatably connected to a third rotating shaft 17, the upper rear side of the pulley group housing 19 is rotatably connected to a first rotating shaft 15, a gear 9 is fixedly connected to the outside of the first rotating shaft 15, the steel cable 28 is slidably connected to the first wire guide wheel 10, the second wire guide wheel 26, the third wire guide wheel 27, and the rubber sleeve 21, and the head and tail of the steel cable 28 are connected end to end.

[0035] During the operation of the device, the rubber sleeve 21 increases the friction between the steel cable 28 and the runner 20, enabling the runner 20 to easily drive the rotation of the steel cable 28. When the pulley group rises to the highest position, the steel cable 28 lifts the steel structure. The head and tail of the steel cable 28 are connected end to end to form a closed loop. When the runner 21 rotates, it drives the entire closed loop to rotate, and the lifted steel structure will also rotate around the center accordingly, realizing flipping.

[0036] Fixed blocks 25 are fixedly connected to the middle of both the left and right sides of the upper end of the base 1. A third wire guide wheel 27 is rotatably connected to the upper end of the fixed block 25, and a second wire guide wheel 26 is rotatably connected to the lower end of the fixed block 25. The fourth rotating shaft 18 passes through the pulley group housing 19 and is fixedly connected to the output end of the second motor 8. The first rotating shaft 15 passes through the pulley group housing 19 and is fixedly connected to the output end of the first motor 7. Bearings 22 are rotatably connected to the outer walls of the second rotating shaft 16 and the third rotating shaft 17, and the bearings 22 are slidably connected to the second pulley groove 14. The pulley group housing 19 is engaged with the first pulley groove 5. The gear 9 is engaged with the caliper 11. An operation screen 23 is fixedly connected to one side of the load-bearing plate 2.

[0037] The first motor 7 drives the gear 9 to rotate, changing the height of the pulley group, thereby lifting the steel structure. The second motor 8 drives the runner 20 to rotate, realizing the rotation of the steel cable 28. Due to the restriction of the third wire guide wheel 27, the other end of the steel cable 28 slides freely between the third wire guide wheel 27 and the second wire guide wheel 26, enabling the cable coil to rotate smoothly. The operation screen 23 can perform unified editing on the motors. When multiple sets of devices need to be spliced to realize the turning over of an ultra-long steel structure, debugging can also be carried out quickly.

[0038] Working principle: The operator operates the screen 23 to drive the first motor 7 to rotate the gear 9, lower the pulley block to the lowest position, the pulley block housing 19 is clamped into the first pulley groove 5, the steel cable 28 is wound in the steel cable groove 6, keep the bearing plate 2 flat, place the steel structure on the bearing plate 2, and then adjust the first motor 7 to raise the pulley block. When the pulley block rises to the highest position, the steel cable 28 lifts the steel structure. The second motor 8 drives the runner 20 to rotate, realizing the rotation of the steel cable 28. The steel cable 28 is connected end to end to form a closed loop. Due to the limitation of the third wire pulley 27, the other end of the steel cable 28 slides freely between the third wire pulley 27 and the second wire pulley 26. When the runner 21 rotates, it drives the entire closed loop to rotate. Under the action of gravity and the friction force of the steel cable 28, the lifted steel structure will also rotate around the center of gravity, realizing flipping. When it is flipped to the appropriate angle, adjust the first motor 7 to lower the pulley block, and the steel structure is newly placed on the bearing plate 2.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
