Abstract
The invention relates to a coal well lower rail car tool, in particular to a hydraulic rail clamping device which solves the technical problems that an existing rail clamping tool is complex in structure, operation wastes time and labor and clamping is unstable. The hydraulic rail clamping device comprises a box body with an opening formed in the lower portion. The movable end of an oil cylinder extends into the box body. The left side and the right side of the portion, close to the front end, of the movable end of the oil cylinder are respectively provided with a first rotating shaft horizontally. The two first rotating shafts are respectively hinged to connection plates. The other end of each connection plate is hinged to a clamping base through a second rotating shaft horizontally arranged at the other end of each connection plate. The lower ends of the two clamping base are oppositely and fixedly connected with a pair of braking vanes. The gap between the two braking vanes is larger than the width of a rail. A pair of third rotating shafts are located on the two side plates perpendicular to the third rotating shafts. The hydraulic rail clamping device fully utilizes the lever principle, converts oil pressure of the oil cylinder into the clamping force of the braking plates, effectively ensures clamping to the rail, and firmly clamps a rail car on the rail. The clamping force can reach 700KN.
Description
Technical field
The present invention relates to the automobile-used tool of colliery lower railway, be specially a kind of hydraulic pressure rail meter.
Background technology
During coal mine operation, fortune coal or the rail vehicle that transports personnel's goods and materials usually need to stop on the rail, because the rail friction force is less, usually need to rail vehicle be fixed on the rail with a special card rail apparatus, bring danger to prevent to slip car.But mostly the card rail instrument that uses at present is to utilize bolt or spring force to make the clamp grip track, its complex structure, operate and relatively take a lot of trouble effort, and because the method for clamping that adopts causes clamping strength inadequate, so that stable not potential safety hazard is located in the rail vehicle existence that stops in orbit.
Summary of the invention
Current track car card rail tool construction is complicated, operating relatively wastes time and energy and the stable inadequate technical matters of clamping, and a kind of hydraulic pressure rail meter is provided in order to solve in the present invention.
The present invention realizes by the following technical solutions: a kind of hydraulic pressure rail meter comprises the casing of a lower openings; The upper plate middle part of casing is provided with opening, opening part vertically is connected with a guide groove, vertically be provided with an oil cylinder in the guide groove, the movable end of oil cylinder stretches into box house, the oil cylinder movable end is provided with first rotating shaft near each level about the position of front end, all is hinged with a connecting panel in two the first rotating shafts; One end of each connecting panel is hinged in the first rotating shaft, and the other end of each connecting panel is hinged with a deck by the second rotating shaft that is horizontally disposed with thereon; The upper end of deck is connected with connecting panel by the second rotating shaft; The middle part of described two decks is provided with semi-circular boss in opposite directions, and two decks contact by semi-circular boss; Each deck is positioned at the equal level of semi-circular boss lower position and has an axis hole, is provided with the 3rd rotating shaft in the axis hole; Described first, second, third rotating shaft is parallel to each other; All vertically having a position-limited trough with position corresponding to each the 3rd rotating shaft on the described casing with on vertical two side plates of the 3rd rotating shaft, described each the 3rd rotating shaft all is located in two position-limited troughs corresponding with it; Side in opposite directions, the bottom of two decks is connected with a pair of braking vane, and described two braking vane spacings are greater than the rail width.
During use, the present invention is fixed on the bottom of rail vehicle over against the position of rail, generally has corresponding hole at the rail vehicle vehicle frame, the casing of hydraulic pressure rail meter is fixed in the hole, oil cylinder is positioned at the top of vehicle frame, and the lower openings of casing is over against rail.When rail vehicle stops to need the location, by outside oil circuit pressure is passed to oil cylinder, the movable end of oil cylinder moves downward, connecting panel, deck moves downward along position-limited trough in company with the 3rd rotating shaft, when the 3rd rotating shaft moves to the bottom of position-limited trough, braking vane has moved to the outside of casing, the 3rd rotating shaft is positioned, the oil cylinder movable end continues to move down, this moment, one end of connecting panel rotated around the first rotating shaft, the other end of connecting panel drives deck by the second rotating shaft and rotates take the 3rd rotating shaft as axle, and two deck top spacings increase, and the braking vane of deck bottom is mutually close and rail clamped; The rotation of deck and clamping are based on lever principle.When needing to remove clamped condition, oil cylinder upwards can be risen, connecting panel drives deck and rotates, deck top move toward one another, the braking vane spacing of deck bottom increases, and unclamps the clamping to rail, clamped condition is removed, then connecting panel, deck and the equal upward movement of the 3rd rotating shaft be not until the top of position-limited trough just can interfere between rail meter and the rail like this.The effect of semi-circular boss is that two decks are propped up mutually, can't clamp rail thereby avoid deck to rotate in advance in the process of operation downwards.
The oil inlet of oil cylinder is connected with bidirectional hydraulic lock by pipeline.
The effect of bidirectional hydraulic lock is to have guaranteed to supply under the oil condition in nothing, and rail meter remains the braking to track, has guaranteed the reliability of braking.
The present invention takes full advantage of lever principle, and the oil pressure of oil cylinder is converted into the gripping power of deck lower end braking vane, and gripping power generally can reach 700KN, has effectively guaranteed the clamping to rail, and rail vehicle firmly is stuck on the rail.The present invention is simple in structure, and clamping is stable, and the operation that clamps and remove clamping is also very simple and reliable.
