Description

Technical Field

[0001] The utility model relates to the technical field of electric power engineering equipment, in particular to a winding device for electric power engineering. Background Art

[0002] Power engineering refers to engineering related to the production, transmission and distribution of electric energy. In a broad sense, it also includes engineering that uses electricity as power and energy in various fields. Cables are often needed in power engineering to enable the power engineering to be better carried out and developed. After use, most cables will be wound and reeled by manpower for next use.

[0003] In the prior art, a Chinese utility model patent document with the announcement number CN217376826U provides a winding device for electric power engineering. The utility model uses a second drive motor to drive the threaded screw to rotate according to the bendability of the cable and the actual winding needs, so that the four outer rods are moved away from or close to each other, thereby adjusting the spacing between the outer rods, so that the device can meet a variety of different usage needs, thereby significantly improving the applicability and practicality of the device; through the design of the first drive motor, the first drive motor is used to drive the rotating seat to rotate, so that the cable can be automatically wound. Compared with the existing manual winding, the automated winding significantly improves the convenience and saves labor costs.

[0004] However, the utility model has the following defects: First, the outer rod and the inner rod are mainly driven by the first drive motor, the second drive motor, the screw rod, and the moving block. The above structure and the inner rod are distributed on the same axis. The overall length of the above structure is too long. When the cable is wrapped around the outer rod, the cable is distributed as a whole at the right end of the device, and the overall weight center is biased to the right, which is not conducive to the balance and stability of the device; second, in addition to being wrapped around the outer rod, the cable is also wrapped around the rotating seat and the mounting seat, and the side plate of the support and the rotating seat are in relative motion. When the cable is wrapped around the rotating seat, the cable near one end of the rotating seat will have obvious friction with the side plate during the winding process, which will not only affect the rotation effect of the device, but also increase cable wear. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-2 The utility model is a winding device for electric power engineering, comprising a support 1, the support 1 comprising a bottom plate, a side plate provided on the top of one end of the bottom plate, an outer rod 12 rotatably mounted on the side plate, a four-jaw chuck provided between the vertical plate and the outer rod 12, the four-jaw chuck comprising a chuck body 2, a clamping claw 10 slidably mounted on the right end of the chuck body 2, an outer rod 12 provided on the ends of the four clamping claws 10 close to each other, and a baffle 13 provided on the ends of the outer rod 12 away from the clamping claws 10.

[0023] The four-jaw chuck is a mature technology and is mostly used in the clamping mechanism of machine tools such as lathes and milling machines. Its transmission mechanism is mainly a gear plate 9 that drives the clamping jaws 10 to move the clamping jaws 10 closer to or farther away from each other. Compared with the screw nut in the prior art, it effectively reduces its own axial length, which is conducive to reducing the proportion of the transmission mechanism in the transverse axial length of the device, thereby making the center of gravity of the outer rod 12 and the wound cable closer to the center position of the device, thereby increasing the stability of the device when winding the cable;

[0024] At the same time, compared with the existing technology, the cable is only wound around the outer rod 12, and the cables on both sides of the outer rod 12 are in contact with the claws 10 and the baffle 13 respectively. The claws 10 and the baffle 13 rotate synchronously to reduce cable wear.

[0025] A gear plate 9 is rotatably provided inside the chuck body 2 . A thread groove is provided on one end of the gear plate 9 close to the clamping claw 10 . The end of the clamping claw 10 close to the gear plate 9 is engaged with the thread groove.

[0026] A slide groove 11 is machined on the chuck body 2, and the claw 10 is slidably installed in the slide groove 11. The claw 10 slides along the radial direction of the chuck body 2. The end of the claw 10 close to the gear plate 9 is also provided with helical teeth. The specific structure is the same as the structure of the four-jaw chuck in the prior art and is used as a transmission mechanism.

[0027] A rotating shaft 14 is provided at the center of the chuck body 2 , and the gear plate 9 is connected to the rotating shaft 14 via a bearing 15 .

[0028] In the present application, unlike the four-jaw chuck structure in the prior art, a rotating shaft 14 is integrally formed at the center position of the chuck body 2 (the four-jaw chuck in the prior art is a hollow structure), and the gear plate 9 is rotatably mounted on the rotating shaft 14 through a bearing 15, and the gear plate 9 and the chuck body 2 can rotate relative to each other.

[0029] An inner rod is provided at one end of the rotating shaft 14 close to the baffle 13 , and an end of the inner rod away from the rotating shaft 14 is connected to the baffle 13 to increase the structural strength of the device.

[0030] The inner wall of the outer rod 12 is slidably connected to the outer support rod, and the inner wall of the inner rod is slidably connected to the inner support rod. The outer support rod, the inner support rod and the baffle 13 are slidably connected via an adjusting block.

[0031] The connection between the outer rod 12, the outer support rod, the inner rod, the inner support rod and the baffle 13 is the same as that in the prior art. An adjustment pin is installed between the inner rod and the inner support rod. There are multiple slots distributed in the axial direction of the inner support rod. The adjustment pin is movably inserted on the inner rod. Figure 1 As shown, the length of the outer rod 12 is adjustable.

[0032] A first gear ring 5 is provided at one end of the gear plate 9 away from the claw 10, and a first drive unit 4 is provided on one side of the first gear ring 5. The first drive unit 4 is installed on the chuck body 2, and a first gear 3 is provided at the working end of the first drive unit 4. The first gear 3 is engaged with the first gear ring 5.

[0033] When the chuck body 2 rotates and drives the outer rod 12 to rotate synchronously, the first drive unit 4, the first gear 3, the first gear ring 5, and the gear plate 9 are also driven to rotate synchronously. The first drive unit 4 and the second drive unit 8 can optionally use motors. The first drive unit 4 drives the gear plate 9, which rotates relative to the chuck body 2, further driving the claw 10 to move.

[0034] A second gear ring 6 is provided at one end of the chuck body 2 away from the claw 10, and a second drive unit 8 is provided on one side of the second gear ring 6. The second drive unit 8 is embedded in the vertical plate, and a second gear 7 is provided at the working end of the second drive unit 8. The second gear 7 is engaged with the second gear ring 6.

[0035] Compared with the existing technology, the second drive unit 8 drives the chuck body 2 to rotate through the cooperation of the second gear 7 and the second gear ring 6, and the second drive unit 8 is located on the side of the second gear ring 6 close to the four-jaw chuck, further reducing the overall axial length of the second drive unit 8 and the four-jaw chuck, thereby improving the stability of the device when winding the cable.

[0036] Working principle: When in use, according to the bendability of the cable and the actual winding needs, the first drive unit 4 drives the gear plate 9 to rotate, and further drives the claw 10 to move, which is used to adjust the spacing of the outer rods 12, drive the four outer rods closer to or away from each other, adjust the spacing of the outer rods 12, and then adjust the length of the outer rods 12. Finally, the second drive unit 8 is started to drive the chuck body 2 to rotate, and the cable is automatically wound.
