The wire drum shaft 2 is supported by the support assembly, and the position of the support assembly can be adjusted as needed, thereby adjusting the position of the wire drum shaft 2. The first brake assembly and the second brake assembly brake the side and end face of the brake disc 3 at the same time, which can provide a more stable braking effect and a faster braking response.
[0021] A further optimized solution is that the support frame includes two support columns 5 fixedly connected to the base 1, a fixed plate 6 is fixedly connected between the two support columns 5, a telescopic electric cylinder 7 is fixedly connected to the fixed plate 6, the telescopic end of the telescopic electric cylinder 7 is fixedly connected to the support assembly, and the support assembly is slidably located between the two support columns 5.
[0022] A further optimized solution is that the support assembly includes a sliding sleeve 8 which is arranged corresponding to the support column 5 and the sliding sleeve 8 is arranged on the outside of the support column 5, a first support plate 9 is fixedly connected between the two sliding sleeves 8, the bottom surface of the first support plate 9 is fixedly connected to the telescopic end of the telescopic electric cylinder 7, a second support plate 10 is arranged above the first support plate 9, and limiting rings 11 are fixedly connected on both sides of the second support plate 10, a rotating sleeve 12 is rotatably connected in the limiting ring 11, and the inner wall of the rotating sleeve 12 and the outer wall of the sliding sleeve 8 are provided with matching threads, the rotating sleeve 12 is sleeved on the outside of the sliding sleeve 8 and is threadedly connected to the sliding sleeve 8, and rollers 13 are rotatably connected on the first support plate 9 and the second support plate 10 respectively, and the rollers 13 are arranged in contact with the wire drum shaft 2. Since the rotating sleeve 12 is threadedly connected to the sliding sleeve 8, the rotating sleeve 12 will move up and down during the rotation process, thereby adjusting the relative distance between the first support plate 9 and the second support plate 10, thereby adjusting it according to the size of the wire drum shaft 2; the first support plate 9 and the second support plate 10 are driven up and down by the telescopic electric cylinder 7, thereby adjusting the position of the wire drum shaft 2, thereby adjusting the wire release height.
[0023] A further optimized solution is that the first brake assembly includes a fixed frame 14 located on the side of the brake disc 3 and rotatably connected to the brake disc 3, a connecting block 15 is fixedly connected between the bottom end of the fixed frame 14 and the first supporting plate 9, a control column 16 is rotatably connected to the fixed frame 14, one end of the control column 16 passes through the fixed frame 14 and is located in the accommodating groove 4, one end of the control column 16 located in the accommodating groove 4 is fixedly connected to a rotating block 17, and the other end of the control column 16 is fixedly connected to a handle 18, two arc plates 19 are provided on the side of the fixed frame 14 close to the brake disc 3, one end of the arc plate 19 is rotatably connected to the fixed frame 14, a push rod 20 is rotatably connected between the middle part of the arc plate 19 and the rotating block 17, and a brake pad 21 is fixedly connected to the side of the arc plate 19 close to the side wall of the accommodating groove 4; the two arc plates 19 and the two push rods 20 are symmetrical about the center of the brake disc 3. The control column 16 is driven to rotate by the handle 18, and then the rotating block 17 is driven to rotate. During the rotation process, the rotating block 17 pushes the two arc plates 19 to move close to the inner wall of the accommodating groove 4 through the push rod 20, thereby driving the brake disc 21 to fit the inner wall of the accommodating groove 4 to brake the brake disc 3.
[0024] A further optimized solution is that the second brake assembly includes a rotating sleeve 12 and a rotating drum 22 arranged on the outside of the fixed frame 14, the control column 16 passes through the rotating drum 22 and is fixedly connected to the rotating drum 22, the connecting block 15 is fixedly connected with a mounting seat 23, the mounting seat 23 is located on the side of the wire drum shaft 2, a vertical plate 24 is fixedly connected to the mounting seat 23, a threaded column 25 is fixedly connected to the vertical plate 24, a rotating gear 26 is arranged on one side of the vertical plate 24, the threaded column 25 passes through the rotating gear 26 and is threadedly connected to the rotating gear 26, a friction plate 27 is fixedly connected to the side of the rotating gear 26 close to the brake disc 3, and a tooth groove matching the rotating gear 26 is provided on the inner wall of the rotating drum 22 corresponding to the rotating gear 26. The control column 16 drives the rotating drum 22 to rotate during the rotation process, and the rotating drum 22 drives the rotating gear 26 to rotate through the tooth grooves on the inner wall. The rotating gear 26 moves axially along the threaded column 25 during the rotation process, thereby driving the friction plate 27 to move toward the brake disc 3, so that the friction plate 27 fits against the side wall of the brake disc 3, and cooperates with the first brake assembly to achieve double-layer braking.
[0025] In a further optimized solution, two conical sleeves 28 are detachably connected to the middle of the reel shaft 2, and the conical surfaces of the two conical sleeves 28 are arranged opposite to each other, so that the pay-off reel can be stabilized in the middle position of the reel shaft 2 to prevent deviation during the pay-off process.
[0026] According to a further optimized solution, a plurality of support rods 29 are fixedly connected between the base 1 and the support column 5 .
[0027] The working process of the present invention is as follows: when in use, the distance between the first support plate 9 and the second support plate 10 can be adjusted by rotating the rotating sleeve 12, so that it can be adjusted according to the size of the wire drum shaft 2. At the same time, the first support plate 9 and the second support plate 10 can be driven up and down by controlling the telescopic electric cylinder 7, so as to adjust the height of the wire drum shaft 2, which is convenient for the wire laying operation. When braking is required, only the handle 18 needs to be pressed down, and the handle 18 drives the control column 16 to rotate, and the control column 16 drives the rotating block 17 to rotate. During the rotation process, the rotating block 17 pushes the arc plate 19 to rotate through the push rod 20, thereby driving the brake disc 21 to contact the side wall of the receiving groove 4, thereby braking. At the same time, the control column 16 will drive the rotating drum 22 to rotate during the rotation process, and the rotating drum 22 drives the rotating gear 26 to rotate through the tooth groove of the inner wall. During the rotation process, the rotating gear 26 drives the friction plate 27 to move toward the side wall of the brake disc 3, thereby braking the side wall of the brake disc 3, thereby achieving double braking.
