The worm drives the first rotating shaft to rotate through the worm gear. The rotation of the first rotating shaft can drive the wire winding roller to rotate to wind up the steel wire. While the steel wire is being wound up, the sliding frame can be driven to move upward through the limiting ring and the second limiting block.

[0021] S3. After placement, start the hydraulic cylinder to drive the rollers to reset. Then start the second motor to drive the second rotating shaft to rotate in the reverse direction to lower the steel wire. At the same time, start the first motor. The rotation of the first motor can drive the screw rod to rotate. The rotation of the screw rod can drive multiple connecting plates to move outward simultaneously, driving multiple sliding blocks to move outward. The sliding blocks drive the wedge block to disengage from the card slot through the sliding rod.

While the steel wire is being wound up, the sliding frame can be driven to move upward through the limiting ring and the second limiting block. When the wedge block is stuck into the card slot, continuing to move upward can drive the wedge block to move outward, compressing the spring until the roof moves to the required height.

[0024] 2. For the steel structure roof lifting and sliding system disclosed by the present invention, when starting the hydraulic cylinder, the hydraulic cylinder can drive the sliding plate to move on one side of the channel steel, driving the rollers to roll in the channel steel, thereby driving the roof to move. While the sliding plate is moving, the counterweight can be driven to slide upward on the second connecting frame through the pulling rope until the roof moves to the required position. At this time, multiple counterweights are completely suspended, keeping the sliding plate balanced.

[0025] 3.

The tops of the plurality of support frames 1 on the same side are fixedly connected with the same channel steel 4. A sliding plate 5 is slidably provided on one side of the channel steel 4. The tops of the two sliding plates 5 are fixedly connected with a plurality of first connecting frames 7. The inner wall of the first connecting frame 7 is penetrated by a first rotating shaft 8 which is rotatably connected. The outer wall of the first rotating shaft 8 is fixedly sleeved with a wire take-up roller 9. The outer wall of the wire take-up roller 9 is fixedly sleeved with a steel wire rope 10 which is wound around the outer wall. The roof 3 is arranged on the top of the workbench 2. The other end of the steel wire rope 10 is connected to the roof 3.

[0041] A hydraulic cylinder 12 is fixedly connected to the top of the channel steel 4, and an output end of the hydraulic cylinder 12 is fixedly connected to one end of the sliding plate 5 to drive the sliding plate 5 to move horizontally;

[0042] The transmission structure is arranged on one side of the first connecting frame 7 and is used to simultaneously drive the plurality of first rotating shafts 8 to rotate so that the lifting and lowering thereof are stable; Figure 4 The transmission structure includes a support plate 19 fixedly connected to one side of the first connecting frame 7, one side of the multiple support plates 19 penetrates and is rotatably connected to the same second rotating shaft 20, the outer wall fixed sleeve of the second rotating shaft 20 is provided with multiple worms 21, the outer wall fixed sleeve of the first rotating shaft 8 is provided with a worm wheel 22 meshing with the worm 21, and one side of the support plate 19 located on the side is fixedly connected to a second motor 18, and the output end of the second motor 18 is fixedly connected to the second rotating shaft 20. In the above technical solution, the second rotating shaft 20 can be driven to rotate by starting the second motor 18, and the rotation of the second rotating shaft 20 can drive the worm 21 to rotate. The worm 21 can drive the first rotating shaft 8 to rotate through the worm wheel 22, thereby driving multiple first rotating shafts 8 to rotate at the same time, and the worm 21 and the worm wheel 22 have a self-locking function to prevent the first rotating shaft 8 from reversing.

[0043] The anti-fall mechanism is arranged on the top of the first connecting frame 7 to prevent the roof 3 from falling when the wire rope 10 breaks; Figure 3 , Figure 4 and Figure 7, the anti-falling mechanism includes a sliding frame 11 slidably arranged through the top of the first connecting frame 7. A concave block 26 is fixedly connected to the top of the first connecting frame 7. A sliding block 27 is arranged on the inner wall of the concave block 26. One end of the sliding block 27 is slidably provided with two sliding rods 28. One end of the two sliding rods 28 is fixedly connected to the same wedge block 29. A plurality of card slots 31 matched with the wedge block 29 are arranged on one side of the sliding frame 11. A spring 30 is sleeved on the outer wall of the sliding rod 28. Two ends of the spring 30 are respectively fixedly connected to the closer sides of the sliding block 27 and the wedge block 29. One end of the steel wire rope 10 away from the wire winding roller 9 is connected to the sliding frame 11. In the above technical solution, through the setting of the wedge block 29, when the sliding frame 11 rises, the wedge block 29 can be driven to compress the spring 30 by the card slot 31 against the wedge block 29, which can ensure the normal rising of the sliding frame 11. When the steel wire rope 10 breaks, when the sliding frame 11 descends, the card slot 31 will contact the wedge block 29 to limit the sliding frame 11, so as to protect the roof 3.

[0044] Refer to Figure 7 , a first motor 16 is fixedly connected to the top of one of the first connecting frames 7. First limit blocks 32 are fixedly connected to both ends of the sliding block 27.

One of the connecting plates 17 is threadedly sleeved on the screw rod 25. In the above technical solution, by starting the first motor 16, the screw rod 25 can be driven to rotate. The rotation of the screw rod 25 can drive the multiple connecting plates 17 to move simultaneously, drive the sliding block 27 to move, and the sliding block 27 can drive the wedge block 29 to move through the sliding rod 28, so that the wedge block 29 completely disengages from the card slot 31, facilitating the normal descent of the sliding frame 11.

[0045] The stabilizing mechanism is arranged below the sliding plate 5 and is used to make the sliding plate 5 more stable when moving. In the above technical solution, through the transmission structure, multiple first rotating shafts 8 can be driven to rotate simultaneously, so that the lifting of the steel wire rope 10 is synchronized. And during the lifting process, the anti-falling mechanism can protect the roof 3 to prevent the roof 3 from falling when the steel wire rope 10 breaks. When the sliding plate 5 moves horizontally, the stabilizing mechanism can also make the sliding plate 5 more stable when moving and will not tilt.

[0046] Refer to Figure 1 、 Figure 2 and Figure 5, the stabilizing mechanism includes two second connecting frames 13 fixedly connected to the ground. A plurality of counterweights 14 are slidably sleeved on the outer wall of the second connecting frame 13. A wire reel 23 is rotatably connected to the inner wall of the second connecting frame 13. The tops of the plurality of counterweights 14 are fixedly connected with the same pulling rope 15 at equal intervals in a penetrating manner. One end of the pulling rope 15 away from the counterweight 14 is fixedly connected to one side of the sliding plate 5. In the above technical solution, when the sliding plate 5 moves, it can drive the pulling rope 15 to move. The movement of the pulling rope 15 can successively pull the counterweights 14 into the air until all the counterweights 14 are suspended in the air. At this time, the lateral position movement of the roof 3 is completed.

[0047] Refer to Figures 1-4 , a plurality of rollers 6 are rotatably connected to one side of the sliding plate 5. The rollers 6 are located in the channel steel 4. In the above technical solution, the setting of the rollers 6 can make the sliding plate 5 move more smoothly.

[0048] Refer to Figure 6 , two groups of second limit blocks 33 are fixedly connected to one side of the sliding frame 11. The steel wire rope 10 penetrates through the second limit blocks 33. A limit ring 24 is fixedly sleeved on the outer wall of the steel wire rope 10. The limit ring 24 is located between the two second limit blocks 33. In the above technical solution, through the cooperation of the limit ring 24 and the second limit blocks 33, when the steel wire rope 10 rises, it can drive the sliding frame 11 to rise through the limit ring 24 and the second limit blocks 33, so that the sliding frame 11 can protect the roof 3 to prevent it from falling.

[0049] A construction method of a steel structure roof lifting and sliding system includes the following steps:

[0050] S1. Place the roof 3 on the workbench 2 for splicing. After splicing, fix one end of a plurality of steel wire ropes 10 to the roof 3. Then start the second motor 18. The second motor 18 can drive the second rotating shaft 20 to rotate. The rotation of the second rotating shaft 20 can drive the worm 21 to rotate. The worm 21 drives the first rotating shaft 8 to rotate through the worm wheel 22. The rotation of the first rotating shaft 8 can drive the wire winding roller 9 to rotate to wind up the steel wire rope 10. While the steel wire rope 10 is being wound up, through the limit ring 24 and the second limit blocks 33, it can drive the sliding frame 11 to move upward. When the wedge block 29 is stuck into the card slot 31, continuing to move upward can drive the wedge block 29 to move outward, squeezing the spring 30 until the roof 3 moves to the required height;

[0051] S2. Start the hydraulic cylinder 12. The hydraulic cylinder 12 can drive the sliding plate 5 to move on one side of the channel steel 4, driving the rollers 6 to roll in the channel steel 4, so as to drive the roof 3 to move. While the sliding plate 5 is moving, it can drive the counterweight 14 to slide upward on the second connecting frame 13 through the pulling rope 15 until the roof 3 moves to the required position. At this time, a plurality of counterweights 14 are completely suspended in the air to keep the sliding plate 5 balanced;

[0052] S3. After the placement is completed, start the hydraulic cylinder 12 to drive the roller 6 to reset. Start the second motor 18 to drive the second rotating shaft 20 to rotate in the reverse direction to lower the steel wire rope 10. At the same time, start the first motor 16. The rotation of the first motor 16 can drive the screw rod 25 to rotate. The rotation of the screw rod 25 can drive a plurality of connecting plates 17 to move outwards simultaneously, and can drive a plurality of sliding blocks 27 to move outwards. The sliding block 27 drives the wedge block 29 to disengage from the clamping groove 31 through the sliding rod 28. At this time, under the action of gravity, the sliding frame 11 makes the second limiting block 33 abut against the counterweight 14, and the next roof 3 is jacked and moved.

[0053] However, as is well known to those skilled in the art, the working principles and wiring methods of the hydraulic cylinder 12, the first motor 16 and the second motor 18 are common knowledge. They all belong to conventional means or well-known common knowledge, and will not be elaborated here. Those skilled in the art can make arbitrary selections according to their needs or convenience.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
