At this time, since the multiple suspension cables 12 have their spacing expanded by the multiple racks 19, the multiple suspension cables 12 will not easily rotate or entangle, and the steel cap beam will not easily rotate significantly. Through the above structure, the rotation amplitude of the steel cap beam can be reduced when the steel cap beam is lifted and moved, so that the steel cap beam is more stable when suspended in the air, and the steel cap beam can be installed more conveniently.

[0024] like Figures 1 to 5As shown, a pair of the second fixed blocks 16 are fixedly connected to the top with a circular plate 20; the middle of the functional cable 13 is fixedly connected with a sleeve 2; the bottom of the sleeve 2 is fixedly connected to the top of the disc 14; the middle of the sleeve 2 is rotatably connected with a large gear 21; the large gear 21 is meshed with a plurality of racks 19; the top of the circular plate 20 is fixedly connected with a fixed seat 22; the bottom of the fixed seat 22 is fixedly connected with a motor 23; the output end of the motor 23 is fixedly connected with a small gear 24; the small gear 24 is meshed with the large gear 21; when working, when it is necessary to adjust the distance between the multiple rings 110 to drive the multiple suspension cables 12 When the distance increases, the slider 113 can be driven to move by multiple electric cylinders 112 to release the movement restriction of the multiple racks 19, and then the motor 23 is started to drive the multiple small gears 24 to rotate, thereby driving the large gear 21 to rotate, and then driving the multiple racks 19 to move synchronously at the same time. After the adjustment is completed, the multiple racks 19 are limited by the movement of the multiple sliders 113. Through the above structure, the positions of the multiple rings 110 can be conveniently adjusted, thereby conveniently reducing or expanding the distance between the multiple suspension cables 12, so that the distance between the multiple suspension cables 12 can be adjusted at any time according to actual needs.

[0025] like Figures 1 to 4 As shown, a fixing ring 3 is fixedly connected to the middle part of the rack 19; the fixing ring 3 is arranged around the middle part of the ring 110; a plurality of through grooves 31 are opened in the middle part of the ring 110; a plurality of rollers 32 are rotatably connected to the middle part of the fixing ring 3; the rollers 32 are arranged inside the fixing ring 3, and the middle parts of the rollers 32 extend into the inside of the ring 110; during operation, after the suspension cable 12 passes through the inside of the plurality of rings 110, the plurality of rings 110 are driven to move upward by the contraction of the functional cable 13, at which time the middle part of the suspension cable 12 will generate rolling friction with the plurality of rollers 32, reducing the contact area between the suspension cable 12 and the inner wall of the ring 110, thereby reducing the friction force between the suspension cable 12 and the inner wall of the ring 110. Through the above structure, the friction between the suspension cable 12 and the inner wall of the ring 110 can be reduced, thereby reducing the damage to the suspension cable 12 and the ring 110 caused by mutual friction.

[0026] like Figures 1 to 5 As shown, the middle part of the functional cable 13 is slidably connected with a protective plate 4; a plurality of springs 41 are fixedly connected to the top of the circular plate 20; the tops of the plurality of springs 41 are fixedly connected to the bottom of the protective plate 4; during operation, when the steel cap beam is fixed by a plurality of suspension cables 12, the suspension cables 12 will be in a relatively loose state, and the middle part thereof will shake. By setting the protective plate 4, the shaking suspension cables 12 can be prevented from colliding with the components on the top of the circular plate 20. Through the above structure, when the steel cap beam is connected by the suspension cables 12, the shaking suspension cables 12 can be prevented from causing damage to the components on the top of the circular plate 20 to a certain extent.

[0027] like Figures 1 to 5 As shown, a bearing 5 is fixedly connected to the middle part of the sleeve 2; the inner ring of the bearing 5 is fixedly connected to the sleeve 2; the large gear 21 is fixedly connected to the middle part of the outer ring of the sleeve 2; when working, when the large gear 21 is driven to rotate by starting the motor 23, the friction between the sleeve 2 and the large gear 21 can be reduced, thereby reducing the load borne by the motor 23. Through the above structure, the load on the motor 23 during operation can be effectively reduced, thereby increasing the service life of the motor 23.

[0028] like Figures 1 to 4 As shown, a plurality of damping rods 6 are fixedly connected to the top of the disk 14; the other ends of the plurality of damping rods 6 are fixedly connected to the bottom of the protective plate 4, and the plurality of damping rods 6 are respectively located inside the plurality of springs 41; during operation, after the steel cap beam is lifted, the protective plate 4 will be suspended in the air and will be shaken by the wind. By setting the damping rods 6, the shaking amplitude of the protective plate 4 in the air can be reduced, thereby reducing the influence of the shaking of the protective plate 4 on the lifting of the steel cap beam.

[0029] like Figure 4 As shown, the middle part of the ring 110 is arranged in an arc shape; the arc-shaped protrusion of the ring 110 is arranged toward the inside of the ring 110; when working, after the distance between the multiple cables 12 is enlarged by multiple rings 110, the cables 12 will form an angle with the upper end surface of the ring 110, and the middle part of the cable 12 will contact and rub with the top of the ring 110. Through the arc-shaped setting of the ring 110, the angle requirement for the contact between the cable 12 and the top of the ring 110 becomes larger, thereby reducing the friction between the middle part of the cable 12 and the top of the ring 110.

[0030] During operation, the multiple suspension cables 12 are respectively passed through the rings 110 and then connected to the steel cap beam. Then, the multiple rings 110 are moved away from each other by adjusting the positions of the multiple racks 19. The multiple sliders 113 are slid into the tooth grooves of the racks 19 through the electric cylinders 112 connected to them, and the racks 19 are limited. Then, the functional cables 13 are contracted by controlling the function alone to drive the disc 14 to rise, and drive the multiple racks 19 to rise, so that the distance between the multiple suspension cables 12 is expanded. Then, the multiple suspension cables 12 are controlled to contract, and the steel cap beam is lifted and suspended. At this time, since the spacing between the multiple suspension cables 12 is enlarged by the multiple racks 19, the multiple suspension cables 12 will not easily rotate or entangle, and the steel cap beam will not easily rotate significantly. When it is necessary to adjust the distance between the multiple rings 110 to increase the distance between the multiple suspension cables 12, the sliders 113 can be driven to move by the multiple electric cylinders 112 to release the movement restrictions of the multiple racks 19, and then the motors 23 are started to drive the multiple small gears 24 to rotate, thereby driving the large gear 21 to rotate, and then driving the large gear 21 to rotate. The plurality of racks 19 are driven to move synchronously. After the adjustment is completed, the plurality of racks 19 are limited by the movement of the plurality of sliders 113. After the suspension cable 12 passes through the plurality of rings 110, the plurality of rings 110 are driven to move upward by the contraction of the functional cable 13. At this time, the middle of the suspension cable 12 generates rolling friction with the plurality of rollers 32, thereby reducing the contact area between the suspension cable 12 and the inner wall of the ring 110, thereby reducing the friction between the suspension cable 12 and the inner wall of the ring 110. When the steel cap beam is fixed by the plurality of suspension cables 12, At regular intervals, the suspension cable 12 will be in a relatively loose state, and the middle part will shake. The protection plate 4 can be set to prevent the shaking suspension cable 12 from colliding with the components on the top of the circular plate 20. When the motor 23 is started to drive the large gear 21 to rotate, the friction between the sleeve 2 and the large gear 21 can be reduced, thereby reducing the load on the motor 23. After the steel cap beam is lifted, the protection plate 4 will be suspended in the air and shake due to the wind. The damping rod 6 can be set to reduce the shaking amplitude of the protection plate 4 in the air.
