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

Embodiment Construction

[0013] Such as figure 1 and figure 2 As shown, the normally closed type intelligent anti-running device is equipped with a crossbeam 6 on the well wall, and a car barrier 7 is installed on the crossbeam 6, and the crossbeam 6 is fixed on the well wall by the corbel. Two buffers 12 are symmetrically installed on the front track of the block 7, and the distance between each buffer 12 and the track is greater than 850mm; the buffer 12 is connected with the block 7. The vehicle barrier 7 is equipped with an executive structure 5 for lifting and lowering the vehicle barrier 7; the upper limit sensor 16 and the lower limit sensor 17 for detecting the state of the vehicle barrier 7 are installed on the executive structure 5; the upper limit sensor 16 and the lower limit sensor The sensor 17 is connected to the controller 3 . The device also has a monitoring box 1 connected with the controller 3 to display the status of the block 7 and an alarm function; a power supply 4 and a swit...

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...
