Drawings
Fig. 1 is a schematic structural diagram of a mine inclined drift sports car protection device.
Detailed Description
The utility model is described in detail with the following figures:
referring to fig. 1, the mine inclined roadway roadster protecting device comprises a track 1, a mine car 2 is connected to the track in a sliding mode, and a roadster protecting assembly is further arranged in the mine inclined roadway.
Sports car protection component includes box 3, and the box is located orbital centre, and the box is less than the track setting.
The bottom fixedly connected with pneumatic cylinder fixed plate 4 of box 3, the pneumatic cylinder fixed plate is the U-shaped. A hydraulic cylinder 5 is fixed on the hydraulic cylinder fixing plate, and a piston rod of the hydraulic cylinder is hinged with a swing baffle 6.
The top of pneumatic cylinder fixed plate is provided with fixed block 7, and it has connecting plate 8 to articulate on the fixed block, and the other end of connecting plate articulates the middle part at swing baffle.
When a piston rod of the hydraulic cylinder extends out, the swing baffle is driven to swing upwards, and the upper part of the swing baffle extends out of the middle of the track and is finally perpendicular to the track. At the moment, the swing baffle can block the mine car with a sports car accident.
When a piston rod of the hydraulic cylinder retracts, the swing baffle is driven to swing downwards, and the top of the swing baffle is finally parallel to the top of the track or slightly higher than the top of the track. At the moment, the mine car can normally pass.
The rear portion of mine car 2 is provided with the buffer, and the buffer includes backup pad 9, and the lower surface of backup pad is provided with the slide rail, and sliding connection has buffer block 10 on the slide rail, and the front end of buffer block passes through spring 11 and links to each other with the mine car.
After the mine car takes place the sports car accident, the buffer block at mine car rear portion is through colliding with swing baffle, and under the effect of spring, the mine car can slow down safely, and the phenomenon of mine car derailment after can not bumping, and the speed reduction effect is splendid.
The sports car protection assembly further comprises a sensor assembly and a PLC (programmable logic controller), the PLC is located in the box body, the sensor assembly comprises a first position sensor 12, a second position sensor 13 and a third position sensor 14, and the first position sensor, the second position sensor and the third position sensor are all electrically connected with the PLC.
