DETAILED DESCRIPTION
[0012] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0013] The utility model of the wire rope winding and unwinding device, such as Figure 1 to Figure 2 As shown, it includes a base 1, on which a first fixed support 2, a first roller 3, a second fixed support 4, a second roller 5 and a third fixed support 6 are sequentially arranged, and the first fixed support 2, the second fixed support 4 and the third fixed support 6 are all fixedly mounted on the base 1; one end of the first roller 3 can be rotatably mounted on the first fixed support 2, and the other end of the first roller 3 is provided with a connecting tube 7, which passes through the second fixed support 4 and is fixedly connected to the second roller 5, and the connecting tube 7 is clearance-matched with the second fixed support 4, and the end of the second roller 5 away from the connecting tube 7 can be rotatably mounted on the third fixed support 6; a motor 8 is arranged in the second roller 5, and the motor 8 is connected to a multi-stage planetary reduction mechanism, and the output end of the multi-stage planetary reduction mechanism is fixedly connected to the first roller 3.
[0014] The base 1 is a thick metal plate used to support various components and integrate them into a whole. The first fixed support 2, the second fixed support 4 and the third fixed support 6 can be fixedly installed on the base 1 by bolts. The first fixed support 2, the second fixed support 4 and the third fixed support 6 are used to support the first roller 3 and the second roller 5. The first roller 3 and the second roller 5 can use the existing wire rope retracting and unwinding rollers. The ends of the first roller 3 and the second roller 5 can be installed on the first fixed support 2 and the third fixed support 6 through bearings. The first roller 3 can be integrally formed with the connecting cylinder 7, and the connecting cylinder 7 can be connected to the second roller 5 through a plurality of bolts, so that the first roller 3 and the second roller 5 are connected into a whole, and the two can rotate synchronously. The connecting cylinder 7 is supported by the second fixed support 4 to improve the stability of the first roller 3, the connecting cylinder 7 and the second roller 5. The clearance between the outer wall of the connecting cylinder 7 and the inner wall of the second fixed support 4 can ensure that the connecting cylinder 7 can rotate. In addition, the connecting cylinder 7 can also be installed on the second fixed support 4 through a bearing.
[0015] The motor 8 is used to provide the power for rewinding and unwinding, and the multi-stage planetary reduction mechanism is used to increase the output torque, driving the first roller 3 and the second roller 5 to rotate stably. The motor 8 and the multi-stage planetary reduction mechanism can be installed on the first fixed support 2 and the third fixed support 6. Both ends of the first roller 3 and the second roller 5 are open, so the motor 8 can be fixedly installed on the third fixed support 6. One end of the multi-stage planetary reduction mechanism is connected to the motor 8, and the other end is installed on the first fixed support 2, which can ensure the stable installation of the motor 8 and the multi-stage planetary reduction mechanism.
[0016] In the utility model, by arranging the motor 8 and the multi-stage planetary reduction mechanism inside the first roller 3 and the second roller 5, the space inside the first roller 3 and the second roller 5 is fully utilized. Compared with the traditional wire rope winding and unwinding equipment, the floor space of the motor 8 and the multi-stage planetary reduction mechanism is saved, making the whole structure more compact and convenient for overall transportation and installation. In addition, by fixing the planetary gear at the output end of the multi-stage planetary reduction mechanism (the output end is the end away from the motor 8, and the end connected to the motor 8 is the input end) to the first roller 3, when the planetary gear rotates, it will drive the first roller 3 to rotate synchronously, and when the first roller 3 rotates, it can drive the second roller 5 to rotate through the connecting tube 7, so as to realize the synchronous rotation of the first roller 3 and the second roller 5, and the wire ropes on the first roller 3 and the second roller 5 can be synchronously wound and unwound.

One end of the three-stage planetary gear reduction mechanism 9 is connected to the motor 8, and the planetary carrier at the other end is meshed with the output planetary wheel 11. The output planetary wheel 11 is arranged on the output planetary carrier 10, and the output planetary carrier 10 is fixedly connected to the first roller 3. The three-stage planetary gear reduction mechanism 9 of the utility model can be completely adopted from the existing technology, including three sun gears, three sets of planetary wheels and multiple planetary carriers. The output planetary wheel 11 is meshed with the planetary carrier at the output end of the three-stage planetary gear reduction mechanism 9. The power of the motor 8 is transmitted to the planetary carrier at its output end after being reduced by the three-stage planetary gear reduction mechanism 9. The planetary carrier drives the output planetary wheel 11 to rotate, and the output planetary wheel 11 can drive the output planetary carrier 10 to rotate, and the output planetary carrier 10 drives the first roller 3 to rotate. The output planetary carrier 10 can be connected to the first roller 3 by bolts. The output planetary wheels 11 can be 4 or 3. The output planetary carrier 10 can be installed on the first fixed support 2 by bearings.
