After the rotating shaft stops rotating, the vertical plate moves back, so that the brake pad can move back to clamp the friction wheel, which is convenient for use.

[0038] The brake control member 910 includes a slide groove 9101 opened at the top of the pressure plate 905, the bottom end of the vertical plate 907 is slidably connected to the slide groove 9101, a fixed plate 9102 is fixedly installed at one end of the top of the pressure plate 905, a third spring 9103 is installed between the vertical plate 907 and the fixed plate 9102, a rotating tube 9104 is provided below the rotating shaft 701, the rotating tube 9104 is rotatably connected to the side plate 3, and one end of the rotating tube 9104 is installed inside the installation cavity 6, and a fan blade 910 is installed at an equal angle on the inner wall of the rotating tube 9104. 5. A stopper 9106 is installed inside one end of the rotating tube 9104 located inside the installation cavity 6. An end plate 9107 is installed at one end of the stopper 9106. A second guide rod 9108 is symmetrically installed on the inner wall of the installation cavity 6. The end plate 9107 is slidably connected to the second guide rod 9108. A gear ring 91012 is installed on the outer side of the rotating tube 9104. A third gear 91013 is installed on the rotating shaft 701. The third gear 91013 is meshed with the gear ring 91012.

When the stopper 9106 moves toward the outside of the rotating tube 9104, the vertical plate 907 is pulled toward the mounting plate 901 by the third connecting rod 9109, so that the first tooth plate 908 corresponds to the second tooth plate 909, and the third gear 91013 on the rotating shaft 701 corresponds to the gear ring on the rotating tube 9104. 91012 are meshed, and when the rotating shaft 701 rotates, it drives the rotating tube 9104 to rotate, and the air pressure at one end of the stopper 9106 is increased through the fan blade 9105, pushing the stopper 9106 to move, and then the vertical plate 907 is pulled toward the mounting plate 901 to the corresponding position of the first tooth plate 908 and the second tooth plate 909 through the third connecting rod 9109, so as to facilitate pushing the pressure plate 905 to move downward. After the rotating shaft 701 stops rotating, the vertical plate 907 moves back, so that the brake pad 902 can move back to clamp the friction wheel 5, which is convenient for use.

[0039] Working principle: When working, firstly wind the cable to be laid around the outside of the winding roller 4, and fix one end of the winding roller 4 at the initial position for laying the cable, and then control the moving seat 1 to move, and the driving motor on the electric moving wheel 2 controls the roller to rotate, and then when moving, the winding roller 4 rotates continuously, so as to continuously roll out the cable for laying, while the existing winding roller 4 is not provided with a power system, and the cable generates a pulling force on the winding roller 4, so that the winding roller 4 rotates to continuously roll out the cable;

[0040] The two limiting plates 7021 limit the airbag 7024, and the rubber friction ring 7025 on the outside of the airbag 7024 contacts the outer wall of the friction wheel 5. At the same time, the limiting plate 7021 is fixedly connected to the rotating shaft 701. The first gear 703 at the end of the rotating shaft 701 and the outer side of the second gear 704 on one of the roller shafts are installed with a synchronous belt 705, so that during the movement, the airbag 7024 and the rubber friction ring 7025 are driven to rotate by the synchronous belt 705. Under the friction force of the rubber friction ring 7025 on the friction wheel 5, part of the power is provided for the rotation of the winding roller 4, thereby reducing the tension generated by the cable on the winding roller 4, and then protecting the cable to avoid the cable being damaged by the large tension.

[0041] When in use, the control electromagnet 806 is energized to generate a repulsive force on the magnetic block 805, so that the sensing rod 801 moves downward and contacts the cable on the outside. When the cable is continuously rolled out, the distance between the outermost cable of the winding roller 4 and the outer wall of the winding roller 4 gradually decreases, so that the length of the cable rolled out by one rotation of the winding roller 4 decreases. At this time, the sensing rod 801 moves downward as the cable is continuously rolled out. When the sensing rod 801 moves downward, the push rod 7029 is pushed toward the airbag 7024 through the first connecting rod 807, so that the air inside the airbag 7024 is The pressure increases. Since the airbag 7024 is limited by the limiting plates 7021 on both sides, the air pressure acts on the rubber friction ring 7025, which increases the pressure of the rubber friction ring 7025 on the friction wheel 5. As a result, the friction force of the rubber friction ring 7025 on the friction wheel 5 increases. Then, as the cable outside the winding roller 4 is continuously rolled out, the kinetic energy provided by the rotation of the rubber friction ring 7025 to the winding roller 4 increases, so that the effect of the rubber friction ring 7025 on the rotation speed of the winding roller 4 is proportional to the amount of cable outside the winding roller 4, which facilitates the cable rolling out.

[0042] Two brake pads 902 are arranged on both sides of the friction wheel 5. When the rotating shaft 701 rotates, the third gear 91013 on the rotating shaft 701 drives the rotating tube 9104 to rotate through the gear ring 91012, and then drives the outside air to continuously enter the rotating tube 9104 through the fan blades 9105, so that the air pressure at one end of the stopper 9106 close to the rotating tube 9104 increases. Under the action of the air pressure, the stopper 9106 moves outward until it moves to the limit position. When moving, the vertical plate 907 is pulled by the third connecting rod 9109 to move along the slide groove 9101 toward the side of the mounting plate 901, so that the first tooth plate 908 corresponds to the second tooth plate 909. When the rotating shaft 701 rotates, the second tooth plate 909 produces a friction force on the first tooth plate 908. The second connecting rod 906 drives the two brake pads 902 to move away from each other. When the cable laying needs to be stopped, the movable seat 1 stops moving. At this time, the rotating shaft 701 and the rotating tube 9104 stop rotating, so that the air pressure at one end of the stopper 9106 is reduced, and the vertical plate 907 is moved back under the elastic force of the third spring 9103, so that the first tooth plate 908 is no longer affected by the second tooth plate 909, so that the two brake pads 902 clamp the friction wheel 5 under the elastic force of the second spring 904, and clamp and fix the winding roller 4 to prevent the winding roller 4 from continuing to rotate under the action of inertia when the cable is stopped, causing excessive winding of the cable, thereby facilitating cable laying.
