Description
Technical field
The utility model belongs to the safety of coal mines equipment technical field, is specifically related to the folding full open type safety door of hydraulic-driven that a kind of coal mine well port is used.
Background technology
According to " safety regulations in coal mine " regulation, coal mine shaft well head and the turnover car side that respectively promotes the stage casing all need be installed safety door, can when cage arrives well head or promotes the stage casing, open, cage leaves well head or close when promoting the stage casing, plays the reliable protection effect.Safety door is opened to be needed flexibly, and helps the various operations in well head and stage casing.Conclusion is got up, and China's coal-mine can be divided into 3 types substantially at the safety door of usefulness, i.e. manually-operated formula, cage drive vertical-lifting, powder actuated.Wherein, that powder actuated can be divided into again that hydraulic cylinder or blast cylinder drive is sliding, collapsible, hinge door leaf formula, Electrohydraulic push rod formula etc.These safety doors respectively have characteristics, and major part all has certain application.Hydraulic-driven because have the safety reliability height, operate steadily, opening and closing speed is fast, impact advantages such as little, is the power-actuated first-selection of present safety door.
Present colliery is poor at the operation stability that exists with safety door mostly, switching motion slow, impact greatly, extremely difficulty maybe can't lengthen down/deficiencies such as aniseed in order to overcome; Some are designed based on hydraulically powered full open type safety door and develop; As the patent No. be the disclosed a kind of hydraulic rotary safety door of ZL200620084256.6 and Liu Wei, Zhu Jianan etc. (see " and Liu Wei, Zhu Jianan, Liu Zhizhong; etc. the development of coal mine shaft swing type safety door. coal; 2006,15 (5): 20-22 ") a kind of swing type safety door of design, and obtain effect of field application preferably.But these safety doors still exist to a certain extent self locking safety property not high, open and close to impact big, the perishable inefficacy of hydraulic cylinder, bar or problem such as beam is easy to wear, durable and aesthetic degree is relatively poor, be difficult to satisfy well application requirements.
The utility model content
The utility model is in order to solve weak point of the prior art, provides that a kind of compact conformation is attractive in appearance, security reliability is high, flexible operation is steady, noise is little, the folding full open type safety door of the hydraulic-driven of long working life.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: hydraulic-driven folds the full open type safety door; Comprise head tree 3, spacing column 1, active crossbeam 5, driven crossbeam 2, hydraulic cylinder 4 and brace 6, hydraulic cylinder 4 is located in the groove of head tree 3, and the clutch end of hydraulic cylinder 4 is with initiatively crossbeam 5 one ends are hinged; Initiatively crossbeam 5 is hinged with head tree 3 respectively with driven crossbeam 2; Initiatively crossbeam 5 laterally arranges with driven crossbeam 2, and brace 6 is hinged with active crossbeam 5 and driven crossbeam 2 respectively, and said spacing column 1 is provided with the load-bearing buffer that cooperates with active crossbeam 5 other ends.
Said spacing column 1 is provided with vertical elongated slot 11; The load-bearing buffer comprises the two-layer guide strip 12 that elongated slot 11 lower horizontal are provided with; Two-layer guide strip 12 correspondences are provided with pilot hole, are equipped with guide rod 9 in the pilot hole, and guide rod 9 lower ends are provided with the locating part 13 that is positioned at lower floor's guide strip 12 belows; Guide rod 9 tops are provided with rubber pad 8, are arranged with the spring 7 between rubber pad 8 and upper strata guide strip 12 on the guide rod 9.
Said active crossbeam 5 is positioned at driven crossbeam 2 belows, initiatively crossbeam 5 be "
﹂" shape, the clutch end of hydraulic cylinder 4 is oblique down hinged with the upper end of the vertical section of active crossbeam 5.
Said driven crossbeam 2 is provided with two-layer at least, brace 6 through pin assemblies 10 respectively with active crossbeam 5 and the folding parallelogram sturcutre of two-layer driven crossbeam 2 hinged formation.
Said every cover pin assemblies 10 is made up of bearing pin 10-1 and two pad 10-2; Initiatively the placement relation at pin assemblies 10 places is followed successively by between crossbeam 5 or driven crossbeam 2 and the brace 6: brace 6, pad 10-2, active crossbeam 5 or driven crossbeam 2, pad 10-2, brace 6; They couple together through bearing pin 10-1, and bearing pin 10-1 two ends are provided with protruding cap 14.
The line at the hinge hole center between described active crossbeam 5, driven crossbeam 2 and the head tree 3 is parallel with brace 6.
