Normally closed type intelligent catcher

Abstract

The invention discloses a normally closed type intelligent catcher belonging to the technical field of mine hoisting equipment protection. The catcher is provided with a car blocking column with a buffer action on a well wall. A performing structure for lifting and descending the car blocking column is arranged on the car blocking column. Two buffers are symmetrically arranged on a track in front of the car blocking column and are connected with the car blocking column. The catcher also comprises a speed sensor for detecting the speed of a mining car, a controller connected with the speed sensor, a monitoring case having the functions of displaying the state of the car blocking column and alarming and connected with the controller, a power supply and a switch which are connected with the controller, wherein the power supply is connected with the performing structure; the speed sensor is arranged on a depth indicator for indicating the lifting/descending depth of a mining car by a winch; an upper limit sensor and a lower limit sensor for detecting the state of the car blocking column are arranged on the performing structure and are connected with the controller. The invention has the advantages of improving the safety in the transportation process of an inclined shaft.

Description

technical field [0001] The invention relates to the technical field of anti-sports car protection for mine vehicles, in particular to a normally closed intelligent anti-sports car device. Background technique [0002] The anti-sports car device is an indispensable equipment in inclined shaft transportation. In case of failure, the anti-sports car device can play a good role in safety protection and ensure the personal safety of the staff. The old-fashioned anti-sports car device is composed of mine I-beam, 6-inch and 4-inch steel pipes, shaft wall fixing devices, hooks, swing rods and wire ropes. When the mine car is overspeed, the mine car hits the swing rod to make the swing rod swing If the amplitude is increased, the swing rod can touch the above car stopper, causing it to fall down and block the mine car; the disadvantage of this method is that the safety factor of the anti-car device is not high. At present, the new anti-sports car device collects the running speed of...

Problems solved by technology

The old-fashioned anti-sports car device is composed of mine I-beam, 6-inch and 4-inch steel pipes, shaft wall fixing devices, hooks, swing rods and wire ropes. When the mine car is overspeed, the mine car hits the swing rod to make the swing rod swing If the range is increased, the pendulum can touch the upper car stopper, causing it to fall down and block the mine car; the disadvantage of this method is that the safety factor of the anti-car device is not high

At present, the new anti-sports car device collects the running speed of the mine car through the sensor installed on the track, and judges the speed of the mine car through the controller, and then lifts and lowers the car block; this method is prone to misoperation , which brings certain hidden dangers to the construction of inclined shafts
