Detailed Embodiment

[0031] In order to make the technical problems, technical solutions and advantages to be solved by the present utility model clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0032] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, in the description of the present utility model, the meaning of "a plurality of" is two or more, unless otherwise specifically defined.

[0033] Figures 1 to 4 The first embodiment of the present utility model is shown: A tensioning and winding integrated device includes a cable winding and unwinding wheel 2 driven by a motor 1. A braking structure 3 is provided on the rotating shaft of the cable winding and unwinding wheel 2. The braking structure 3 includes a brake disc 301 that rotates synchronously with the winding and unwinding wheel 2. An arc-shaped brake pad 302 is arranged around the brake disc 301. The head end of the brake pad is fixed in the circumferential direction of the brake disc 301, and the tail end of the brake pad is connected to an operating rod 303. The operating rod 303 can trigger the arc-shaped brake pad 302 to tighten towards the brake disc 301 to achieve braking or emergency stop through friction.

[0034] Please refer to Figure 4 , during specific implementation, an old cable recycling wheel is also connected to the rotating shaft of the cable winding and unwinding wheel 2. The cable winding and unwinding wheel 2 is in transmission connection with the output shaft of the motor 1 through a transmission structure 5. The transmission structure 5 includes a sprocket assembly 501 and a gear assembly 502.

[0035] As Figure 1As shown in the figure, considering the installation and transportation problems of the device, in order to ensure the compactness of the device, a first vertical plate 6 is provided between the brake disc 301 and the cable winding and unwinding wheel 2, a second vertical plate 7 is provided between the cable winding and unwinding wheel 2 and the transmission structure 5, and a third vertical plate 8 is provided between the transmission structure 5 and the old cable recovery wheel. The head end of the operating rod 303 is rotatably connected to the first vertical plate 6, and the end of the arc-shaped brake pad 302 is movably connected to the rod body of the operating rod 303 through a U-shaped lock 304. When the operating rod 303 is pulled, it can ensure that a section of the arc-shaped brake pad 302 wraps the brake disc 301, so as to apply a frictional force to the brake disc 301 through the arc-shaped brake pad 302, forcing the brake disc 301 to decelerate to a stop, so as to achieve the braking or emergency stop effect on the cable winding and unwinding wheel 2.

[0036] From Figure 2 and Figure 4 It can be seen that in this embodiment, the tensioning and releasing integrated device further includes a frame 9, and the motor 1, the first vertical plate 6, the second vertical plate 7 and the third vertical plate 8 are arranged on the frame 9. Preferably, in order to improve safety protection, a cross bar 10 is connected between the first vertical plate 6 and the third vertical plate 8, and a protective cover 11 is rotatably connected to the cross bar 10.

[0038] In the second embodiment, we further considered the actual application of the cable traction device on the harvesting locomotive head 13. Since the harvesting locomotive head 13 itself has powerful power and moving ability, modifying it into a cable traction device can greatly improve the efficiency of cable construction. Especially in vast areas such as mountains and fields, the harvesting locomotive head 13 has wide adaptability and can easily cope with various terrains and complex environments.

[0039] In this embodiment, the ground ridge structure 12 of the harvesting locomotive head 13 is retained, and this structure can ensure the stability of the harvesting locomotive head 13 during the tensioning and releasing operation. At the rear part, we installed the tensioning and releasing integrated device described above, including key components such as the motor 1, the cable winding and unwinding wheel 2, the braking structure 3, and the old cable recovery wheel. Through careful design and reasonable layout, these components ensure the compactness and high efficiency of the entire device.

[0040] In summary, the cable winding and unwinding wheel 2 driven by the motor 1 in the present utility model, in combination with the braking structure 3, realizes the rapid winding and unwinding of the cable and emergency braking, greatly simplifies the operation process, and improves the work efficiency; the braking structure 3 provided on the rotating shaft of the cable winding and unwinding wheel 2 can quickly achieve braking or emergency stop in case of emergency, effectively reducing the safety risks of the equipment and personnel. At the same time, by setting structures such as the protective cover 11, the safety of the equipment is further enhanced; by integrally installing various components with multiple vertical plates, the device has a smaller volume and a light weight, facilitating installation and transportation; through the setting of the old cable recycling wheel, the recycling and reuse of waste cables are realized, which conforms to the environmental protection concept; the present utility model is modified based on the harvesting locomotive head 13, making the cable traction equipment have strong adaptability and flexibility.
