specific Embodiment approach 1

[0005] Specific implementation mode one: the following combination figure 1 and figure 2 This embodiment will be specifically described. This embodiment consists of a frame-shaped main frame 3, two slideways 1, safety railings 2, bearing housings 4, through shafts 5, screw nuts 17, levers 8, left travel switches 6, right travel switches 18, and rollers 9. , reducer 10, motor 11 and steel wire rope 12, the through shaft 5 is set horizontally on the upper top of the main frame 3 through the bearing seat 4, the roller 9 is fixed on the through shaft 5 and rotates coaxially with the through shaft 5, and the lead screw Nut 17 is screwed in the lead screw that is opened in the middle section of through shaft 5 length direction, and driving rod 8 is fixed on the leading screw nut 17, and left travel switch 6 and right travel switch 18 are respectively arranged on the left and right sides of driving rod 8. At the two cut-off positions, one end of the through shaft 5 is connected to...

specific Embodiment approach 2

[0006] Specific implementation mode two: the following combination figure 2 , Figure 4 and Figure 5 This embodiment will be specifically described. The difference between this embodiment and Embodiment 1 is that it also includes the moving contact ZC of the upwell contactor, the moving contact FC of the downhole contactor, the on-board sensor 13, the off-board sensor 14, the program controller 20, the forward rotation The contactor 21 and the reverse contactor 22, one end of the moving contact ZC of the upper well contactor and the moving closing contact FC of the lower well contactor are connected to the power supply VCC, and the other end of the moving closing contact ZC of the upper well contactor is connected to the vehicle sensor 13 One connection terminal of the left travel switch 6 and the moving contact of the left travel switch 6, the other end of the downhole contactor moving contact FC is connected with a connection terminal of the alighting sensor 14 and the m...

specific Embodiment approach 3

[0007] Specific implementation mode three: the following combination image 3 This embodiment will be specifically described. The difference between this embodiment and the first embodiment is that the rod body 2-1 of the safety railing 2 is a steel pipe, and a steel wire rope 2-2 is passed through the inner cavity of the rod body 2-1. So set, the anti-collision strength of safety railing 2 is big.

Abstract

The invention relates to an inclined shaft sports car prevention safety door device, concretely relates to an mine inclined shaft safety device prevented mine car from automatically sliding back to the inclined shaft. Feed-through shaft is set at the top of the main frame. Roller is fixed at the feed-through shaft and did coaxial rotation with it. Its one end is connected to the output shaft of the electric machine by the speed reducer. The up end of the wire rope is twined at the roller, and the down is fixed at the top of the insurance balustrade. It is set in the vertical two slide ways. The plane with the two slide ways is paralleled with the plane with the main frame. After the mine car is ran in the inclined shaft and passed through the main frame, the electric machine is rotated along the clockwise, and drove the feed-through shaft to rotate, the insurance balustrade is put down. When the mine car is run away, the insurance balustrade is rose up. The insurance balustrade is put down at once when the mine car is run. This can avoid that the protective measures can not be brought into effect in time after the accident happened. And the operation of rising up and putting down the protective device are not need handwork.

Description

Technical field: [0001] The invention relates to a safety device for preventing a mine car from slipping back into the shaft in an inclined shaft of a mine. Background technique: [0002] At present, the mine car is the main means of transportation in the mine inclined shaft production. Because the exit of the inclined shaft has a certain slope, it is easy for the mine car to slip back into the well due to abnormal reasons, causing accidents. In order to prevent the occurrence of such accidents, the country has required each wellhead to realize the protective measures of "one slope and three gears" in production operation, that is, there must be three obstacles to prevent sports cars. These three gears include manually forcing the mine car to fall off the track, manually closing the safety door, and manually setting up the cart net. Obviously, these methods are not the way to prevent in advance. It is easy to be caught off guard after a sports car occurs, and the risk of m...
