[0023] 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.

[0024] See also Figures 1-4 , the utility model provides the following technical solutions:

[0025] A braking device for unfolding a cable reel comprises a placement plate 2, an electric lock 4, a vertical electric telescopic rod 5 and a horizontal electric telescopic rod 6. The horizontal electric telescopic rod 6 is installed at both ends of the horizontal electric telescopic rod 6, and the end of the horizontal electric telescopic rod 6 is installed with an electric lock 4. It also comprises a driving roller 9, which is located at the bottom of both ends of a cable reel body 1. The driving roller 9 supports the cable reel body 1. A fixing rod 7 is installed on the placement plate 2. The placement plate 2 is located at the end position of the cable reel body 1. The electric lock 4 is located at the lower side of the cable reel body 1. The electric lock 4 locks the cable reel body 1.

[0026] The position of the driving roller 9 is adjusted according to the specifications of the cable drum 1. After the driving roller 9 is adjusted, the cable drum 1 is placed on the driving roller 9, and then the cable drum 1 can be unfolded. After the cable drum 1 is unfolded, the vertical electric telescopic rod 5 and the horizontal electric telescopic rod 6 are controlled to move the electric lock 4 to fit the side of the cable drum 1. The electric lock 4 locks the cable drum 1 to prevent the cable drum 1 from being unstable. The cable drum 1 is supported by the setting of the driving roller 9, which can prevent the entire weight of the cable drum 1 from acting on the electric lock 4, thereby protecting the electric lock 4.

[0027] An adjusting mechanism is provided at the end of the cable drum body 1, which changes the position of the driving roller 9. Cable drum bodies 1 of different specifications are used. The adjusting mechanism includes a slide 3, a rotating bevel gear 10, a threaded rod 11 and a fixed bevel gear 12. The slide 3 is opened on the placement plate 2, and the driving roller 9 slides inside the slide 3, and the driving roller 9 slides inside the slide 3; the threaded rod 11 is rotatably connected to the end of the fixed rod 7, and the other end of the threaded rod 11 is threadedly connected to the driving roller 9; a rotating rod 8 is rotatably connected to the placement plate 2, and the rotating bevel gear 10 is fixed on the threaded rod 11. The solid bevel gear 12 is installed at the bottom end of the rotating rod 8, and the rotating bevel gear 10 and the solid bevel gear 12 are engaged with each other. The central angles corresponding to several rotating bevel gears 10 are on the same horizontal line with the center of the rotating rod 8, and the slide 3 is parallel to the threaded rod 11.

[0028] When the position of the drive roller 9 needs to be adjusted, the rotating rod 8 is manually rotated. The rotation of the rotating rod 8 drives the fixed bevel gear 12 to rotate synchronously, thereby causing the fixed bevel gear 12 to revolve. When the fixed bevel gear 12 rotates to mesh with the rotating bevel gear 10, the fixed bevel gear 12 rotates the rotating bevel gear 10, which in turn drives the threaded rod 11 to rotate synchronously. The threaded rod 11 rotates and moves the drive roller 9. The drive roller 9 slides within the chute 3. The rotation angle of the fixed bevel gear 12 is a multiple of 360 degrees, so that all the drive rollers 9 move at the same distance, forming an arc, avoiding tilting when supporting the cable drum 1 and maintaining stability. The central angle formed by several drive rollers 9 is less than 180 degrees. The drive rollers 9 are in an inverted "T" structure. Several drive rollers 9 are arranged in an arc below the cable drum 1. The drive rollers 9 are located between the electric locks 4 on both sides. The lower end of the placement plate 2 protrudes from the lower end of the horizontal electric telescopic rod 6, and the placement plate 2 is directly in contact with the ground.
