Description

technical field [0001] The invention relates to a start-stop synchronous suspension rail type safety brake protection device.

Problems solved by technology

The mechanical suspension rail brake has a huge structure. Although the braking torque is relatively large, the braking process is relatively short, and it is easy to generate a large impact, resulting in unstable braking and accidents.

Although the braking process of the hydraulic hanging rail brake is more stable than that of the mechanical type, it can realize stepless speed regulation during the braking process, but there are many kinds of hydraulic components in the hydraulic system, which makes the hydraulic system too complicated and the operation is cumbersome. At the same time, the hydraulic braking system adopts The open system is easily affected by the surrounding environment. After the oil is polluted, the entire system (especially important valves) often fails to work normally

Neither of these two methods can achieve start-stop synchronization. At present, during the working process of many transportation equipment, especially in downhill conditions, the sliding force generated by the gravity of the material greatly exceeds the running resistance. When parking and braking, The sliding force all acts on the braking device, resulting in a sudden increase in the acceleration of the transportation equipment, which may easily lead to the failure of the braking device and cause speeding, causing injuries and other accidents
