Description

Technical Field

[0001] This utility model relates to the field of flexible braking technology, and in particular to a flexible low-speed brake. Background Technology

[0002] The flexible low-speed brake has very high requirements for the control of hydraulic oil. The threaded cartridge valves used are mainly imported and expensive. The hydraulic station is made of aluminum alloy, and the oil circuit integration block, an important part, is made of aerospace aluminum alloy to ensure reliable strength.

[0003] The flexible braking method uses an overflow valve in conjunction with a flow control valve to achieve flexible braking in low-speed braking. The principle of low-speed braking is that the mechanical force generated by the "compression" and "release" of the disc spring is transmitted to the brake disc through the friction pads.

[0004] However, the use of conventional brakes currently in place results in inertia during braking, which can easily damage equipment and transported materials. Utility Model Content

[0005] The purpose of this invention is to provide a flexible low-speed brake, which solves the problem that conventional brakes used in the prior art cause inertia during braking, leading to easy damage to equipment and transported materials.

[0006] To achieve the above objectives, this utility model provides a flexible low-speed brake, comprising a low-speed brake and a flexible hydraulic station. The low-speed brake includes a base, a bracket, two cylinder units, a flow divider, and a main flow pipe. The bracket is welded to the base and located at the upper end of the base.

The multiple bolts pass through the fixing plate and are respectively located inside the bracket. The hydraulic cylinder is fixedly connected to the side of the fixing plate. The output end of the hydraulic cylinder passes through the fixing plate and is fixedly connected to the friction plate. One end of the oil pipe is connected to the lower end of the hydraulic cylinder, and the other end of the oil pipe is connected to the diverter block.

[0010] The parallelism of the friction plate is controlled to be 0.1 mm. One end of the main flow pipe is connected to the branch block, and the other end of the main flow pipe is fixedly connected to the accumulator.

[0011] This utility model discloses a flexible low-speed brake. The flexible hydraulic station is made of an all-aluminum structure, which is corrosion-resistant, lightweight, and has good heat dissipation. The cylinder unit is equipped with a disc spring shell, which compresses the disc spring through liquid pressure to generate a reliable force to produce a stable and reliable flexible braking force on the disc braking system.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] This utility model provides a flexible low-speed brake, including a low-speed brake and a flexible hydraulic station. The low-speed brake includes a base 1, a bracket 2, two hydraulic cylinder units 5, a flow divider 3, and a main flow pipe 4. The bracket 2 is welded to the base 1 and is located at the upper end of the base 1. The two hydraulic cylinder units 5 are respectively located at the upper end of the base 1 and on both sides of the bracket 2. The flow divider is fixedly connected to the rear end of the bracket 2. One end of the main flow pipe 4 is connected to the flow divider 3, and the other end of the main flow pipe 4 is connected to the flexible hydraulic station.

[0021] In this embodiment, the flexible hydraulic station is made of an all-aluminum structure, which is corrosion-resistant, lightweight, and has good heat dissipation. The cylinder 5 unit is equipped with a disc spring shell, which compresses the disc spring through liquid pressure to generate a reliable force to produce a stable and reliable flexible braking force on the disc brake system. The structure has been improved to obtain a new and novel structure and performance. Both the performance and the size of the structure have been comprehensively improved, making it a new type of machine structure that meets modern use. Through the cooperation of the flexible hydraulic station and the low-speed brake, the device can slowly trigger the brake disc and then perform flexible braking to avoid inertial damage to the equipment and transported materials during braking.

[0022] Further, each of the hydraulic cylinder 5 units includes a hydraulic cylinder 5, a friction plate 6, a fixing plate 7, multiple bolts 8, and an oil pipe 9. The fixing plate 7 is disposed on the side of the bracket 2, and the multiple bolts 8 pass through the fixing plate 7 and are respectively located inside the bracket 2. The hydraulic cylinder 5 is fixedly connected to the side of the fixing plate 7, and the output end of the hydraulic cylinder 5 passes through the fixing plate 7 and is fixedly connected to the friction plate 6. One end of the oil pipe 9 is connected to the lower end of the hydraulic cylinder 5, and the other end of the oil pipe 9 is connected to the diverter block 3. The flexible hydraulic station includes an accumulator 10, a threaded cartridge valve 11, a control box 12, a motor 13, and an oil tank 14. The accumulator 10 is disposed on the oil tank 14, the motor 13 is disposed at the lower end of the oil tank 14 and located at the upper end of the base 1, the control box 12 is fixedly connected to the rear end of the oil tank 14, and the threaded cartridge valve 11 is disposed on the accumulator 10. The flexible hydraulic station also includes a temperature sensor 15, a liquid level sensor 16, a manual control valve 17, and an electrical box 18. The temperature sensor 15 is located at the upper end of the oil tank 14, the liquid level sensor 16 is located at the upper end of the oil tank 14, the electrical box 18 is located at the rear end of the oil tank 14 and above the control box 12, and the manual control valve 17 is located on the oil tank 14.

[0023] In this embodiment, when the power is off, the flexible hydraulic station slowly depressurizes. At this time, the pressure in cylinder 5 decreases, the disc spring opens, and the friction pads 6 slowly move inward to grip the brake disc, thus performing flexible braking. When released, the flexible hydraulic station is powered on to rapidly pressurize cylinder 5. At this time, the pressure in cylinder 5 increases, the disc spring contracts, and the friction pads 6 quickly move outward to release the brake disc. The brake disc is positioned between the two friction pads 6, and braking is achieved through the friction pads 6. Oil flows into the diverter block 3 through the main flow pipe 4, then into the oil pipe 9, and finally into cylinder 5. The temperature in the oil tank 14 is monitored in real time by the temperature sensor 15, and the oil level in the oil tank 14 is detected by the level sensor 16. Furthermore, the flexible hydraulic station is an improvement on the original ordinary hydraulic station, becoming a flexible hydraulic station by externally attaching the threaded cartridge valve 11. The flexible brake is used in scenarios requiring flexible braking, such as high-speed conveyor belts. These application scenarios ensure the safe and stable operation of the equipment.
