[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 4In an embodiment of the utility model, a winding device for power construction includes a base plate 1, and two symmetrically arranged support frames 2 are fixedly connected to the top of the base plate 1. Rotating shafts 3 are rotatably installed on the inner sides of the two support frames 2, and end plates 5 are fixedly connected between the two support frames 2. A winding drum 6 is fixedly connected between the two end plates 5, and a hand wheel 4 is fixedly connected to the outer periphery of the two rotating shafts 3; a plurality of limiting grooves 19 are equidistantly provided on the inner circumference of the end plates 5, and a limiting mechanism is arranged inside the two support frames 2, and a locking mechanism for limiting the limiting mechanism is fixedly connected to the top of the base plate 1.

[0020] In this embodiment, when the cable is unwinding, a downward pulling force is applied to the limiting mechanism until the limiting mechanism is completely separated from the limiting groove 19. At this time, the two end plates 5 are no longer restricted. At the same time, the limiting mechanism moving downward contacts and squeezes the locking mechanism. The compressed locking mechanism rotates and resets after rotating, thereby locking the limiting mechanism and limiting the limiting mechanism to the lower position. Then, one end of the cable is pulled to move. When the cable moves, it drives the reel 6 to rotate, thereby realizing the unwinding function.

[0021] After the cable is used, the handwheel 4 is turned, and the handwheel 4 drives the winding drum 6 to rotate through the rotating shaft 3, and the winding drum 6 can reel in the cable. After reeling is completed, a limit groove 19 is aligned with the limit mechanism, and then the locking mechanism is stepped on to rotate the locking mechanism again to release the lock of the limit mechanism. At this time, the reset limit mechanism limits the end plate 5 and the cable to avoid loosening and unwinding during transportation.

[0022] Please refer to Figure 1 and Figure 2 The limiting mechanism includes a slide groove 7 opened on the inner side of the two support frames 2, and the inner wall of the slide groove 7 is connected to a slider 12 for sliding up and down. The bottom end of the slider 12 is fixedly connected to a spring 13 fixedly connected to the top of the base plate 1, and a limiting rod 8 is fixedly connected between the two sliders 12.

[0023] In this embodiment, by applying a downward pulling force to the limiting rod 8 , the limiting rod 8 drives the two sliders 12 to move downward along the sliding groove 7 , and the spring 13 is compressed during this process.

[0024] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4The locking mechanism includes two fixing ears 9 fixedly connected to the middle part of the top of the base plate 1, and a locking head 10 is rotatably installed between the two fixing ears 9. The top of the locking head 10 is integrally formed with a downwardly inclined pressure inclined surface 15, and the end of the locking head 10 away from the pressure inclined surface 15 is fixedly connected to the foot pedal 11. The locking mechanism also includes a receiving groove 17 opened at both ends of the locking head 10, and one end of the inner wall of the receiving groove 17 is fixedly connected to a rotating shaft 16 rotatably connected to the fixing ear 9, and a torsion spring 18 is fixedly connected between one end of the inner wall of the receiving groove 17 and the fixing ear 9.

[0025] In this embodiment, as the limiting rod 8 moves downward, it gradually contacts and squeezes the pressure inclined surface 15 on the top of the locking head 10. At this time, the locking head 10 rotates with the rotating shaft 16 as the center of the circle, and the locking head 10 drives one end of the torsion spring 18 connected thereto to rotate accordingly, while the other end of the torsion spring 18 is in a stationary state. During this process, the torsion spring 18 is twisted until the limiting rod 8 is misaligned with the pressure inclined surface 15. At this time, the torsion spring 18 is reset, and the reset torsion spring 18 drives the locking head 10 to rotate and reset, thereby locking the limiting rod 8 and preventing it from resetting upward.

[0026] After the cable is wound up, the locking head 10 is rotated again by stepping on the pedal 11 to release the locking of the limit rod 8, and the limit rod 8 is reset upward under the spring 13.

[0027] Please refer to Figure 3 The top of the bottom plate 1 is fixedly connected to the limit plate 14, and the top of the limit plate 14 contacts the bottom end of the pressure inclined surface 15 in the reset state.

[0028] In this embodiment, when the locking head 10 is rotated and reset, the top of the limiting plate 14 can limit the reset state of the locking head 10 to avoid the locking failure caused by excessive reset.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
