Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and a detailed implementation manner and a specific operation process are provided, but the protection scope of the present invention is not limited to the present embodiment.
The embodiment provides a contact net motor-driven pay-off device, as shown in fig. 1-2, which comprises a vehicle body flat plate 1, a driving wheel 2, a driven wheel 3, a seat 4, a hydraulic oil cylinder 5, a wire coil fixing frame 6, a brake holding frame 7, a wire coil supporting shaft 8, a shaft seat 9, a first support 10, a second support 11, a driven shaft 12, a driving shaft 13, an engine device 14 and a brake holding device;
the brake device comprises a brake roller 15, a hydraulic oil cylinder 5, a brake frame 7 and a bottom bracket 16; the brake holding frame 7 comprises a base 71, a pull rod 72 and upright rods 73, the base 71 is fixed on the top of the bottom support 16, the upright rods 73 are respectively arranged on two sides of the base 71, the bottom ends of the upright rods 73 are rotatably connected with the base 71, so that the upright rods 73 on two sides can rotate in opposite directions or in opposite directions, one end of the pull rod 72 is connected to the top end of the upright rod 73 on one side, and the other end of the pull rod 72 is connected to the hydraulic oil cylinder 5; the brake roller 15 is clamped between the two vertical rods 73; the bottom bracket 16 is fixed with the vehicle body panel 1;
