[0014] 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.

[0015] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0016] Reference Figure 1-2 The present invention provides a ratchet-type pay-off stand with a brake function, comprising a first support frame 1 and a second support frame 2. A pay-off shaft 3 is rotatably arranged between the first support frame 1 and the second support frame 2. Both ends of the pay-off shaft 3 pass through the first support frame 1 and the second support frame 2, respectively. A brake disc 4 is fixedly connected to the end of the pay-off shaft 3 close to the first support frame 1. A brake assembly is installed on the first support frame 1. The brake assembly and the brake disc 4 are arranged correspondingly. A non-return assembly for controlling the brake assembly is installed on the first support frame 1. The brake pads 8 in the brake assembly cooperate with the brake disc 4 to achieve control of the pay-off shaft 3. Braking can be completed by simply pulling the toggle lever 10. It is easy to control and has a short reaction time, and the braking operation can be completed in time. The non-return assembly can control the brake assembly to ensure the braking state of the brake assembly, and there is no need for workers to pull the toggle lever 10 for a long time.

[0017] To further optimize the solution, the brake assembly includes a first gear 5 and a second gear 6 that are rotatably connected to the first support frame 1. The first gear 5 is meshed with the second gear 6. The first gear 5 is located above the second gear 6. A connecting column 7 is fixedly connected to the side face of the second gear 6. A brake pad 8 is slidably connected to the side wall of the first support frame 1. The brake pad 8 is located below the brake disc 4 and is arranged corresponding to the brake disc 4. A push rod 9 is rotatably connected between the connecting column 7 and the bottom wall of the brake disc 4. The second gear 6 is coaxially fixedly connected to a connecting rod, and a toggle rod 10 is fixedly connected to the end of the connecting rod. By pulling the toggle rod 10, the second gear 6 is driven to rotate, and then the first gear 5 is electrically rotated. During the rotation process, the first gear 5 will push the push rod 9 to rotate through the connecting column 7, thereby pushing the brake pad 8 to fit the brake disc 4 and braking the pay-off shaft 3.

[0018] A further optimized solution is provided, in which the non-return assembly includes a ratchet 11 rotatably connected to the first support frame 1. The ratchet 11 is fixedly connected to the second gear 6 via a connecting shaft, which passes through the first support frame 1 and is rotatably connected to the first support frame 1. A rotating rod 12 is rotatably connected to the first support frame 1, and the rotating rod 12 is set through the first support frame 1. One end of the rotating rod 12 is fixedly connected to a pawl 13, which is adapted to the ratchet 11. The other end of the rotating rod 12 is fixedly connected to a pedal 14, and a reset spring 15 is fixedly connected between the pedal 14 and the bottom of the first support frame 1. The ratchet 11 is limited by the pawl 13, so that the second gear 6 and the toggle lever 10 remain at the braking state angle, eliminating the need for workers to constantly pull the toggle lever 10, saving manpower. When it is necessary to continue paying out the line, one only needs to step on the pedal 14, which drives the pawl 13 to rotate through the rotating rod 12, so that the pawl 13 no longer limits the ratchet 11, and then reset the toggle lever 10.

[0019] Further optimization scheme, two cone sleeves 16 are detachably connected to the pay-off shaft 3, and the two cone sleeves 16 are arranged oppositely. Through the two oppositely arranged cone sleeves 16, the cables can be gathered in the middle of the pay-off shaft 3 to prevent the cables from running away.

[0020] Further optimizing the solution, a U-shaped groove 17 is formed on both the first support frame 1 and the second support frame 2, and the pay-off shaft 3 is located in the U-shaped groove 17. A pressure block 18 is detachably connected to the U-shaped groove 17 through a pin. The pressure block 18 is located above the pay-off shaft 3 and is in contact with the pay-off shaft 3. By installing the pressure block 18 in the U-shaped groove 17 through the pin, the pay-off shaft 3 can be limited to prevent jumping during the pay-off process.

[0021] The working process of the present invention is as follows: when in use, the pay-off shaft 3 is placed in the U-shaped groove 17, and the pressure block 18 is fixed above the pay-off shaft 3 with a pin to prevent the pay-off shaft 3 from jumping during rotation. When braking is required, the toggle lever 10 is pulled, and the toggle lever 10 drives the second gear 6 to rotate, thereby driving the first gear 5 to rotate. During the rotation of the first gear 5, the brake pad 8 is pushed upward through the connecting column 7, thereby contacting the side of the brake disc 4 and braking the pay-off shaft 3; at the same time, the second gear 6 drives the ratchet 11 to rotate during rotation. When the toggle lever 10 is pulled, the pawl 13 limits the ratchet 11, thereby limiting the second gear 6, so that the second gear 6 and the toggle lever 10 remain at the angle when braking, and the worker does not need to pull the toggle lever 10 all the time. When it is necessary to continue to pay out the line, only the pedal 14 is pressed, and the pawl 13 is driven by the rotating rod 12 to stop limiting the ratchet 11, and the toggle lever 10 is restored to its position.

[0023] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
