Description

Novel air door switch system Technical Field The utility model belongs to the technical field of roadway air door pneumatic control systems, and particularly relates to a novel air door opening and closing system. Background In the traffic management of mine roadways, in order to realize automatic control of air doors and improve traffic efficiency of vehicles and personnel, a pneumatic control system is generally adopted to control the opening and closing of the air doors. In the traditional scheme, a pull switch control system (also called a pull box control system) is often used as a non-electric control pneumatic switching means, and the basic principle is that a pull wire arranged at the front, rear and middle top of a damper is pulled to trigger a pneumatic control box to finish the opening and closing operation of the damper. The system usually needs to arrange branch pipelines at two ends of a roadway, extend control signals from a wire pulling device to a pneumatic control box, and execute opening and closing actions of an air door by a compressed air driving cylinder. However, in actual use, the traditional box pulling system has the following problems that 1, the failure rate is high, and because the pull wire and the pneumatic switch are complex in structure and are easily affected by external force interference or dust, misoperation, clamping stagnation or failure are often caused. 2. The installation difficulty is high, the system relates to a plurality of air source branches and mechanical connection points, the installation process is complicated, the cables and the pipelines are required to be accurately arranged manually, and the construction period is long. 3. The maintenance is inconvenient, the distribution of system components is dispersed, the gas paths are staggered and complicated, once faults occur, the time consumption of the troubleshooting and replacing process is long, and the maintenance efficiency is low. 4. The pipeline management is complex, and a plurality of air source control pipelines are hung on the roadway roof, so that the arrangement confusion or the traffic safety interference can be easily caused. In summary, the existing damper stay wire control system still has a plurality of technical bottlenecks in the underground mine environment, and a novel damper switch system with optimized structure, concise wiring and convenient maintenance is needed to improve the operation reliability and the field management efficiency of the mine damper system. Disclosure of utility model The utility model provides a novel air door switch system, which aims to solve the technical problems of high failure rate, difficult installation, more parts and pipelines, mess hanging, difficult maintenance and high cost of an air door in the use process. The technical scheme includes that the novel air door switch system comprises a pull box, the pull box is connected with an air compressing system through an air pipe and used for supplying air to an air door, the pull box is inversely fixed on a roadway side wall on one side of a roadway, two fixed pulleys are arranged on the roadway side, right above the pull box, close to a top plate, of the side roadway side, switch control pull ropes of the pull box extend upwards around the fixed pulleys respectively and horizontally and oppositely, ends of the switch control pull ropes are fixed on the roadway side, close to the top plate, of the opposite side roadway side, an auxiliary switch control pull rope is fixedly connected to a horizontal section of the switch control pull rope, and the lower ends of the auxiliary switch control pull ropes drop to the upper portion of a bottom plate. Further, two auxiliary switch control pull ropes are arranged on the horizontal section of each switch control pull rope at a certain distance, and the two auxiliary switch control pull ropes are respectively positioned at two sides of a roadway lane.
