Abstract

The utility model relates to an overrunning governor for the hanging cage of a shaft-well, being a hoisting safety device for the shaft-well. The utility model is composed of a cage body, a guide rope, a guide wheel group, eccentric overrunning governors, an operating handle, etc. The eccentric overrunning governors are arranged on two edges of the guide rope of two sides of the cage body. The guide wheel group and an eccentric wheel group drive a pull plate by the operating handle and a turning plate. So the eccentric wheel generates friction with the guide rope when the eccentric wheel moves so that the aim that personal casualty which is resulted from the falling over-speed and the squatting cage of the hanging cage is effectively controlled is achieved. Compared with the prior art, the utility model has the advantages of simple structure and convenient and flexible operation, and is a safety transportation device for the shaft-well.

Description

Overrunning governor for cage of shaft-well

The utility model belongs to mine hoisting device technique field, is specifically related to a kind of shaft hoisting safety device.

In medium and small colliery, most of mine uses the transportation mode of shaft hoisting cage, and this mode causes owing to cage is not of uniform size, and the shape disunity does not have safety device again; When cutting off the power supply in the malfunctioning or lifting process when winch, descending speed is too fast, causes jar major accident of back personal casualty of squatting, and this phenomenon is the normal thing that takes place in the vertical shaft transportation, has been to compel as pressing as a fire singeing one's eyebrows so solve the safety problem of vertical shaft cage.

The utility model overcomes the deficiencies in the prior art part and provides a kind of simple in structure, the velocity limiter that restriction cage speed that can be safe and reliable descends.

The utility model is to realize like this, vertical shaft cage velocity limiter, comprise tank body, tank body guide rope, lead wheels, operating handle down, it is characterized in that eccentric velocity limiter being housed on the both sides of tank body both sides guide rope, velocity limiter is made up of track adjusting wheel, eccentric wheel and operating mechanism, be fixed with the eccentric wheel arm-tie that links to each other with handle with flap on the eccentric wheel, handle is contained in is convenient to passenger from line operate in the cage.

The eccentric driving surface of the utility model speed limit is a spill, matches with guide rope.

Description of drawings:

Fig. 1 is the mounting structure scheme drawing of vertical shaft cage velocity limiter on cage.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the constructional drawing of velocity limiter.

Label declaration:

1, handle 2, velocity limiter 3, down lead wheels 4, flap 5, arm-tie 6, guide rope 7, bolt 8, adapter plate 9, wheel shaft 10, eccentric wheel 11, arm-tie set pin 12, tank body 13, on lead wheels 14, track adjusting wheel

With reference to the accompanying drawings embodiment is further described, the utility model is a kind of conveying arrangement that is exclusively used in the vertical shaft colliery, guiding velocity limiter 2 is fixed on the both sides of the both sides guide rope 6 of tank body 12 by bolt 3, the eccentric wheel 10 of velocity limiter and the track adjusting wheel 14 that matches with it and guiding wheels 13 are contained on the adapter plate 8, arm-tie 5 is fixed on the eccentric wheel 10, flap 4 hinge joints are on the framework of tank body 12, handle 1 links to each other with arm-tie 5 by flap 4, when cage normally moves, operating mechanism is quiescence, at this moment, eccentric wheel 10 is that locate under action of the spring in the axle center with off-centre, be hang and guide rope and keep certain distance, under the effect of track adjusting wheel, both sides are not rubbed.When the cage descending speed is accelerated passenger in decline, feel and speed up, to the person when dangerous, operating handle 1 voluntarily, power a little downwards, eccentric wheel 10 is subjected to displacement with guide rope 6 produces friction, utilize the strength that descends, eccentric wheel 10 natures and guide rope 6 lock, thereby play the purpose that cage speed slows down or stops.

The utility model compared with prior art has simple in structure, compact; Flexible and convenient operation, safe and reliable and can effectively control to descend and overrun causes personnel casualty accidents behind the crouching tank, is the product that a kind of update is provided for shaft transport.

Claims

1, a kind of vertical shaft cage velocity limiter, comprise: tank body, tank body guide rope, guiding wheels, operating handle, it is characterized in that eccentric velocity limiter 2 being housed on the both sides of tank body 12 both sides guide ropes 6, eccentric velocity limiter 2 is made up of guiding wheels 13 eccentric group 10,14 and operating mechanism 1,4,5, is fixed with the eccentric wheel arm-tie 5 that links to each other with handle 1 with flap 4 on the eccentric wheel 10.

2, velocity limiter according to claim 1, its feature is a circular arc at the driving surface of ground speed limit eccentric wheel 10, matches with guide rope 6.
