Abstract
The invention relates to an emergency braking device for a descending mine car. The mine car comprises a plurality of carriages connected with each other in a hung manner, the rear of the last carriage is fixedly connected with a steel wire rope of a winch, fixed pulleys are symmetrically mounted on the top of the carriage front and back, a steel wire hang rope is connected into grooves of the fixed pulleys in a bridged manner, two ends of the hang rope respectively extend to the front and the back of the carriage, the rear end of the hang rope is fixedly connected with the steel wire rope of the winch, the front end of the hang rope droops down from the front of the carriage and is connected with a transverse stop lever in a suspension manner, the length of the transverse stop lever is approximately equal to the perpendicular distance of center lines of two tracks, downward clamping jaws are symmetrically perpendicularly connected to two ends of the stop lever and can be clamped into the tracks to stop the mine car from advancing, and two ends of the stop lever are respectively connected with diagonal digging ropes which are fixedly connected with the hang rope in an upwards diagonal tension manner. The emergency braking device for the descending mine car is simple in structure, the tracks can be clamped under emergency, the winch is stopped from continuing running, safety of workers and facilities can be effectively guaranteed, and the emergency braking device has high practicality.
Description
Technical field
The present invention relates to a kind of brake gear, especially a kind of descending mine car emergency braking apparatus.
Background technology
Under mine, go down the hill to adopt the winch transportation on the inclined plane, when mine car is descending; If brake failure; Steel rope is broken, and then mine car rushes at the tunnel, below with get out of hand with higher speed; Mine personnel and facility are caused huge threat, and also not having preferably so far, method solves this problem.
Summary of the invention
In order to solve mining mine car uncontrollable problem under the situation of brake failure; The present invention proposes a kind of descending mine car emergency braking apparatus; This apparatus structure is simple, can promptly block track, stops mine car to continue to go; Can effectively ensure the safety of workman and facility, have better practicability.
The technical solution adopted for the present invention to solve the technical problems is: this descending mine car emergency braking apparatus comprises lifting rope, fixed pulley, pin, claw; Said mine car is made up of the more piece compartment that articulates each other, captives joint with winch cable in the rear portion in its final section compartment, and the traction mine car goes up and down along track; The top in said compartment, front and back are symmetrically installed with the fixed pulley of directional tagging; Stride across in the groove of said fixed pulley and be connected with wire sling; Extend to the front and back in compartment respectively at the two ends of said lifting rope; Captive joint with winch cable in the rear end of said lifting rope, the front end of said lifting rope hangs down from the front portion in compartment, and suspension is connected with the approximately equalised horizontal pin of vertical distance of length and two track centres; The two ends symmetry of said pin vertically is connected with downward claw, can snap in track and stop mine car to move ahead; The two ends of said pin are connected with the upward oblique rope of captiveing joint with lifting rope that draws respectively, to keep the balance of pin; When running into the open circuited situation of winch cable, said pin promptly can fall to be stuck in and stop mine car to move ahead between the track.
The invention has the beneficial effects as follows: this descending mine car emergency braking apparatus is simple in structure, can promptly block track, stops winch to continue to go, and can effectively ensure the safety of workman and facility, has better practicability.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Accompanying drawing 1 is the example structure scheme drawing of this descending mine car emergency braking apparatus.
Among the figure, 1. winch cable, 2. lifting rope, 3. fixed pulley, 4. pin, 5. claw, 6. compartment, 7. track.
The specific embodiment
In accompanying drawing 1, this descending mine car emergency braking apparatus comprises lifting rope 2, fixed pulley 3, pin 4, claw 5; Said mine car is made up of the more piece compartment that articulates each other, captives joint with winch cable 1 in the rear portion in its final section compartment 6, and the traction mine car goes up and down along track 7; The top in said compartment 6, front and back are symmetrically installed with the fixed pulley 3 of directional tagging; Stride across in the groove of said fixed pulley 3 and be connected with wire sling 2; Extend to the front and back in compartment 6 respectively at the two ends of said lifting rope 2; Captive joint with winch cable 1 in the rear end of said lifting rope 2, the front end of said lifting rope 26 front portion hangs down from the compartment, and suspension is connected with the approximately equalised horizontal pin 4 of vertical distance of length and two tracks, 7 center lines; The two ends symmetry of said pin 4 vertically is connected with downward claw 5, can snap in track and stop mine car to move ahead; The two ends of said pin 4 are connected with the upward oblique rope of captiveing joint with lifting rope 2 that draws respectively, to keep the balance of pin 4; When running into winch cable 1 open circuited situation, said retaining 4 bars promptly can fall to be stuck in and stop mine car to move ahead between the track.
