Abstract
The invention discloses a fall-preventing brake sliding carriage and a fall-preventing brake method for a hoist bucket of a vertical shaft. The fall-preventing brake sliding carriage comprises a carriage body sleeved on a hoist steel wire rope, two springs and support seats which are symmetrically fixed on a top beam of the carriage body, levers hinged with the support seats, connecting plates connected with the upper parts of the levers, connecting blocks hinged with the connecting plates, four guide sleeves which are symmetrically fixed on longitudinal beams at two sides of the carriage body and sleeved on stable ropes, two fall-preventing catch forceps which are symmetrically fixed on the longitudinal beams at two sides of the carriage body as well as a self-locking mechanism. When the hoist steel wire rope is broken above the sliding carriage, the hoist bucket quickly falls off and a rope cappel downwards slides into a lower sliding wedge along with the downwards-moving hoist steel wire rope to drive the sliding wedge to downwards move; the hoist steel wire rope is clamped by the self-locking mechanism on the sliding carriage; the sliding carriage is clamped on the stable ropes by the fall-preventing catch forceps; and the hoist bucket of the hoist steel wire rope is prevented from falling and is protected. The sliding carriage can be used for guiding for the hoist bucket and also has the functions of fall-preventing protection, automatic combination and separation from the hoist steel wire rope and the like. The sliding carriage is simple in structure and favorable in fall-preventing effect.
Description
Technical field
The present invention relates to the anti-fall braking balladeur train of a kind of vertical shaft hoisting well-bucket and anti-fall braking method, be particularly useful for the guiding of hoist bucket of construction vertical shaft and anti-fall, be also applicable to the vertical-lifting container guiding of rope guiding with anti-fall.
Background technology
At present, in most of vertical construction projects, use the waste rock discharge device of well-bucket as construction.Well-bucket, by wire rope suspensioning, moves up and down in shaft of vertical well.In order to prevent shaking in process that well-bucket moves in pit shaft, conventionally use the guide piece of balladeur train as well-bucket.But existing carriage apparatus can only provide guide function for well-bucket, when hoisting cable generation fracture accident, can not provide anti-falling protection for well-bucket.Existing bucket falling protector; that balladeur train is improved; balladeur train can for providing, well-bucket be led and anti-fall function simultaneously; but this balladeur train is to compress hoisting cable by spring force; when there is rope-broken accident; balladeur train can not effectively be firmly grasped hoisting cable, when the well-bucket weight of below is larger, still can not guarantee actv. anti-falling protection.
Summary of the invention
Technical matters: the object of the invention is to overcome the weak point in prior art, provide a kind of compact conformation simple, anti-fall effective and there is the anti-fall braking balladeur train of vertical shaft hoisting well-bucket and the anti-fall braking method of directional tagging.
