Description
Technical field
The utility model relates to belt braking device under the coal mine, is specially the safe folding and unfolding braking device of a kind of inclined shaft pressure adjustable.
Background technique
When the coal mine inclined shaft belt conveyor is installed lay belt or regularly tape swapping work, because the gradient is large, during the lay belt, belt glides and runs band is the great difficult problem that perplexs tiltedly to advance belt conveyor lay belt always, and runs the band accident in case occur will cause heavy losses to the colliery safety in production.
Traditional lay belt braking device, general lever pressurization friction catch and the bolt card sub-folder band principle braking dual mode of adopting controlled the belt downslide, adopt lever pressurization friction catch to need many people simultaneously afterburning control of lever to be put tape speed or braking, and reinforcing can not rest, thereby that often personnel are inharmonious because cooperating, the factor such as inhomogeneous of exerting oneself causes belt to glide is too fast, lose control of, cause the band accident of running.
The bolt card sub-folder closes the principle braking device, owing to be by tight nut pressurization braking, so time spent of every braking is longer, cause belt to glide in case occur not stepping up, often have little time the secondary reinforcing, will cause and run the band accident because of too fast the losing control of of gliding, can cause sizable damage to belt even control also.
More than during the operation of two kinds of braking device, from the belt slideway close to, in case accident occurs, often because of the belt swing of gliding fast, cause casualty accident.
Summary of the invention
The utility model is put the easy problem that occurs to run with accident and casualty accident of band in order to solve existing braking device control, provides a kind of inclined shaft pressure adjustable safe folding and unfolding braking device.
The utility model is to adopt following technological scheme to realize: the safe folding and unfolding braking device of inclined shaft pressure adjustable, comprise the support that is arranged on the belt left and right sides, be fixed with the lower supporting rod that is positioned at the belt below between the bottom of two stands, be fixed with upper connecting rod between the top of two stands, and be provided with the upper supporting rod that slides up and down and be positioned at the belt top along it between the two stands, two hydraulic jacks that distribute about being provided with between upper connecting rod and the upper supporting rod, the two ends of hydraulic jack are connected with upper supporting rod with upper connecting rod by oil cylinder seat, and be connected with hydraulic system by pipeline in two oil pockets of hydraulic jack, hydraulic system comprises oil sump, oil hydraulic pump, motor, relief valve, filter, three position four-way directional control valve, pressure gauge, reversible lock, modulating valve, the oil inlet end of oil hydraulic pump and oil revolving end are communicated with oil sump, and be provided with relief valve between the oil revolving end of oil hydraulic pump and the oil sump, the power intake of oil hydraulic pump is connected with the output shaft of motor, the hydraulic pressure delivery side of pump is communicated with the input end of filter, the output terminal of filter is communicated with the input end of three position four-way directional control valve, and be provided with modulating valve between the two, two output terminals of three position four-way directional control valve and the corresponding connection of two oil cylinders of hydraulic jack, and be provided with reversible lock between the two, be provided with pressure gauge between three position four-way directional control valve and the reversible lock.
When the oil hydraulic pump operating stem is got to " clamping " position, under the effect of motor, hydraulic oil in the oil sump is successively in oil hydraulic pump, filter, modulating valve, reversible lock enter an oil pocket of hydraulic jack, the elongation of driving hydraulic jack, supporting rod glides in the promotion, cooperates with lower supporting rod belt is compressed; When operating stem is got to " unlatching " position, hydraulic oil in the oil sump in oil hydraulic pump, filter, modulating valve, reversible lock enter another oil pocket of hydraulic jack, drives hydraulic jack and shrinks successively, and is sliding on the supporting rod in the pulling, cooperate with lower supporting rod belt is unclamped, stop braking; When manometric oil pressure reached load, oil returned oil sump through relief valve, had overcome existing braking device control and had put the easy problem that occurs to run with accident and casualty accident of band.
The utility model reasonable in design is reliable, drives the work of belt clamp holder by hydraulic jack, and the unlatching of clamp holder, braking function in the realization in the time of time saving and energy saving, can be controlled to belt at safe distance, have guaranteed personal security fully; And can brake fully belt within 3 seconds, can also regulate belt friction, thoroughly solve the problem that the lay belt runs band, and in the work of reclaiming old band, saved the production time.
