Problems solved by technology

[0002] Inclined mine car rail transportation is a transportation method widely used in coal mines and other mines. Its transportation form is to pull the mine car group by a winch installed above the inclined shaft. Due to various reasons, the traction wire rope is often prone to breakage. Safety accidents causing car crashes and fatalities
At present, mines have adopted various anti-car systems, but all of them have defects of one kind or another, and have not been able to form a perfect solution

Embodiment Construction

[0015] As shown in the figure: a single-track double-wedge braking system for inclined shaft mine car rail transportation, its characteristics are: the braking system includes a frame 2, a pull rod 1 is mounted on the frame, and a brake spring 6 is located at the lower end of the pull rod. There is also a manual key 4 on the frame, and a key baffle plate 5 on the brake key; the pull rod is connected with a frame structure composed of connecting rod 10 and rod 8 through bolts; there are guide rods in the frame 17. There are guide rod bearings 11 respectively up and down the guide rod, and springs 13 and sliding rollers 14 are fixed on the guide rod bearings by adjusting nuts 12; there are also movable wedges 15 and fixed wedges 16 on the guide rods, wherein Protruding wings are arranged below the moving wedge 15.

[0016] Described guide rod 17 is supported by guide rod bearing 11, and guide rod bearing is fixed on the frame 2, has rectangular hole on the guide rod bearing,...

Abstract

The invention relates to transportation of a mine car rail, in particular to a double-wedge block braking system for a transportation monorail of an inclined shaft mine car rail. The braking system comprises a frame, wherein a pull rod is arranged on the frame; a brake spring is arranged at the lower end of the pull rod; a brake key is also arranged on the frame; a key baffle plate is arranged on the brake key; the pull rod is connected with a frame structure formed by a connecting rod and a rod through a bolt; a guide rod is arranged in the frame; the upper side and the lower side of the guide rod are provided with a guide rod support respectively; the guide rod supports are fixedly provided with springs and sliding rollers through regulating nuts; a movable wedge block and a fixed wedge block are arranged on the guide rod; and a protruded wing is arranged on the lower side of the movable wedge block. Once rope breaking accidents occur in a winch for dragging a mine car group, a brake vehicle between two mine cars drives the movable wedge block to move under the action of spring force, the movable wedge block is tightly wedged between the fixed wedge block and the rail, and the brake vehicle is blocked on a brake rail, so that the whole mine car group can be braked.

Description

technical field [0001] The invention relates to a mine car rail transportation, in particular to a monorail double-wedge braking system for an inclined shaft mine car rail transportation, belonging to the technical field of mine safety. Background technique [0002] Inclined mine car rail transportation is a transportation method widely used in coal mines and other mines. Its transportation mode is to pull the mine car group by a winch installed above the inclined shaft. Due to various reasons, the traction wire rope is often prone to breakage. A safety accident that caused a car crash. Mine has adopted multiple anti-car systems at present, but all there is such and such defective, can not form a kind of perfect solution. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art and provide a single-track double-wedge brake system for inclined shaft mine car rail transportation. The brake ...
