Car-sliding-prevention self-adjusting buffer system for transportation on oblique alley and application of system

Abstract

The invention relates to a car-sliding-prevention self-adjusting buffer system for transportation on an oblique alley and application of the system. The system comprises a mine car lifting winch, a car barrier lifting system and a car barrier buffer system; through sensors arranged on an upper car yard, the oblique alley, a lower car yard and a mine car, conditions of the mining car during transportation on the oblique alley of a coal mine are monitored in real time and transmitted to a controller through a signal repeater arranged along the oblique alley, and the controller collects data of each sensor to judge whether or not there is an accident during transportation and controls each subsystem to make corresponding actions and adjustments to prevent occurrence of the accident. The car barrier buffer system is additionally arranged in a car sliding prevention device, so that the buffering process is more stable and controllable. At the same time, a buffer device in the car barrier buffer system adopts a magnetorheological buffer for cooperating with a pressure sensor and a speed sensor, so that the problem is solved that buffering forces of conventional car barrier system cannotbe automatically adjusted according to the weight of mine cars and the speed of the mine cars.

Description

technical field [0001] The invention relates to a sports car-proof self-adjusting buffer system for inclined lane transportation and its application, belonging to the technical field of mine transportation. Background technique [0002] The lifting and transportation of inclined shafts is an important part of the entire mine transportation system, and it is also an important link in mine safety production. It is responsible for lifting coal, rocks, lowering equipment and materials, and some are also used for lifting personnel. However, due to reasons such as decoupling of mine cars and broken ropes, it has become a frequent area for mine transportation accidents. [0003] According to statistical data, in the daily mining and production of coal mines, accidents in coal mine transportation are the second largest accidents in terms of the number of occurrences and the impact caused, and among them, the accidents caused by mine trucks and sports cars accounted for the largest n...

Problems solved by technology

However, with this design idea, when adjusting the buffer resistance of the buffer energy-absorbing device, the screw rod must be manually adjusted, and real-time adjustment and correction cannot be made for the running speed of the mine car and the weight of the mine car. limitation

[0006] Chinese patent ZL201610157787.1 designed an anti-car system for inclined lanes in coal mines, which is mainly composed of inclined lane rails, mine cars, steel wire ropes, car barrier wire mesh, surrounding rock anchorage for inclined lanes, speed sensors, consoles, etc., and is installed on mine cars The speed sensor on the wheel shaft detects the running speed of the mine car. When the sensor detects that the mine car is overspeed, it controls the lowering of the car stop net; if the buffer resistance is too large, the mine car will derail and other accidents will occur, and the buffer resistance is too small. An issue that would cause minecarts to be unable to intercept a sports car accident

[0007] None of the above design ideas solves the problem of how to adjust the buffer damping force in real time according to the weight and speed of the mine car to effectively improve the safety and reliability of the system
