[0023] Among them, the winding roller 6 and the hanging rope 8 are provided with multiple, multiple winding rollers 6 are coaxially fixedly connected, multiple winding rollers 6 and hanging ropes 8 work cooperatively, can more evenly share the weight of information sign, improve the stability of hoisting process, ensure that when hoisting larger size information sign, can also operate safely and smoothly.

[0024] In addition, the top surface of the installation plate 3 is also rotatably installed with a roller 10, and the plurality of hanging ropes 8 are arranged around the roller 10. The setting of the roller 10 changes the movement direction of the hanging ropes 8, reduces the friction between the hanging ropes 8 and the installation plate 3, makes the hanging ropes 8 more smooth in the process of winding and unwinding, prolongs the service life of the hanging ropes 8, and also improves the flexibility of hoisting operation.

[0025] Example 2

[0026] The embodiment is based on the driving assembly of embodiment 1, and specifically comprises the following:

[0027] Please refer to Figures 3-5 The driving assembly comprises a hollow disc 11, movable plates 12, connecting rods 13, rotating members 14, push-pull rods 15 and a power unit. The hollow disc 11 is fixedly installed on the back of the mounting plate 3. Four movable plates 12 are movably arranged around the periphery of the hollow disc 11. The four movable plates 12 are arranged in one-to-one correspondence with the four limiting corners 4. The movable plates 12 are connected to the limiting corners 4 through the connecting rods 13. The mounting plate 3 is provided with strip-shaped holes 16 for the sliding of the connecting rods 13. The two ends of the push-pull rod 15 are symmetrically fixedly installed with rotating members 14. One of the rotating members 14 is rotatably installed on the mounting plate 3, and the other rotating member 14 is arranged in the hollow disc 11. The side of the hollow disc 11 is provided with a side hole for the sliding of the push-pull rod 15. The power unit is used to provide power for the synchronous movement of the plurality of push-pull rods 15 in or out of the hollow disc 11. The driving assembly drives the movement of the push-pull rod 15 through the power unit, and then drives the synchronous movement of the movable plate 12 and the limiting corner 4. The distance between the limiting corners 4 can be conveniently adjusted to adapt to the installation requirements of information signs of different sizes and improve the versatility of the device.

[0028] Specifically, the power unit comprises a fixed ring 17, a first bevel gear 18, a second bevel gear 19 and a screw rod 20. The fixed ring 17 is fixedly installed in the hollow disc 11 and is arranged concentrically with the hollow disc 11. The first bevel gear 18 is rotatably installed in the fixed ring 17. The periphery of the first bevel gear 18 is meshingly provided with the same number of second bevel gears 19 as the push-pull rod 15. The second bevel gears 19 are fixedly installed with the screw rod 20 at the shaft center. The screw rod 20 is rotatably arranged in the hollow disc 11, and the screw rod 20 is installed with a screw sleeve 21 matched therewith. The other rotating member 14 is rotatably installed on the screw sleeve 21. The power unit utilizes bevel gear transmission and the screw rod 20 screw sleeve 21 structure. When the first bevel gear 18 rotates, the screw rod 20 is driven to rotate through the second bevel gear 19, so that the screw sleeve 21 drives the synchronous movement of the push-pull rod 15, realizing the synchronous and accurate adjustment of the plurality of limiting corners 4, which is simple and convenient to operate and has high adjustment accuracy.

[0029] In addition, the hollow disc 11 is further rotatably installed with a knob 22 connected with the first bevel gear 18. The knob 22 is arranged to facilitate the manual rotation of the first bevel gear 18 by the operator, thereby controlling the movement of the limiting corner 4. The operation is intuitive and convenient, and no additional tools are needed, which improves the efficiency of replacing the information sign.

[0030] Working principle:

[0031] When replacing the information signboard, first, the hook 9 on the hanging rope 8 is hung on the appropriate position of the information signboard, the knob 22 outside the hollow disc 11 is rotated, the knob 22 drives the first bevel gear 18 to rotate, the first bevel gear 18 meshes with the peripheral second bevel gear 19, so that the plurality of second bevel gears 19 rotate synchronously, the second bevel gear 19 drives the screw rod 20 at the shaft center to rotate, the screw sleeve 21 on the screw rod 20 moves on the screw rod 20, the screw sleeve 21 drives the push-pull rod 15 to slide in the side hole of the hollow disc 11 through the rotating part 14, the movement of the push-pull rod 15 drives the movable plate 12 to slide around the mounting plate 3 through the rotating part 14, the movable plate 12 drives the limiting corner 4 to move away from the center of the mounting plate 3 through the connecting rod 13, so as to release the fixation of the signboard.

[0032] Then, the servo motor 7 outside the long barrel cover 5 is started, the servo motor 7 drives the winding roller 6 to rotate, the hanging rope 8 is lowered, after the old signboard is removed, the hook 9 on the hanging rope 8 is hung on the appropriate position of the new information signboard, the servo motor 7 is started again, the hanging rope 8 is wound, the information signboard is hung up by the hanging rope 8, the installation personnel climb up the ladder to assist the signboard to be pasted between the four limiting corners 4, and the signboard is pasted tightly on the mounting plate 3, finally, the knob 22 is reversely rotated, the four limiting corners 4 can fix the new signboard again, so as to complete the replacement of the information signboard.
