Abstract
The utility model relates to an arrival-advance track anti-slide, belonging to the ground facilities of the railway vehicle deceleration and anti-sliding device. It comprises a double-acting cylinder, a swing plate hinged on the brake frame having two fulcrums respectively hinged to the double-acting cylinder and the driving medium of the link mechanism that is a spring hinged to the link mechanism and the swing plate, a brake track connecting with the link mechanism composed of a connecting rod and double swing links hinged to the brake frame. A swing arm is arranged on the swing plate cooperating with the backstop fixed to the brake frame of one side; a frontstop is arranged on one side of the swing link to cooperate with it, which can realizes automatic lock, brake effectively and release easily. It is suitable for the circuitry of the intermediate station or at the end of composing lines of the marshalling station on which anti-sliding of the vehicles is needed to decelerate the slinding of the vehicles and stop them.
Description
Technical field
The utility model is applicable to that to the anti-device that slips of hair line marshaling yard departure track afterbody or intermediate station need prevent on the circuit of wagon running away, makes humping of cars speed slow down, stop, and belongs to the anti-wayside equipment that slips of rolling stock deceleration.
Background technology
The anti-slide facility of marshaling yard departure track or intermediate station mainly is a brake shoe at present, and armrest work industry labour intensity is big, dangerous, also influences efficient.And the anti-slide device (comprising car retarder, stopping device) that uses mostly in the marshalling station is the single shaft clamp type structure, because its brake clamp vertical distance apart from the rail end face when buffering horizontal throw big, the side is little, gauge too high lateral opening in top is narrow partially when promptly alleviating, can only be limited in the marshalling station and use, be unsuitable for hair line.
In order to address the above problem, the big spacing of a kind of lower bound anti-device that slips of lever that makes up tong is disclosed in the Chinese patent 97227676.9, its technical scheme feature is: brake clamp and bearing connect to form four-bar linkage through pivoted arm, force transmission mechanism is the reinforcement crank throw transmission device of eccentric wheel type, crank throw is provided with support roller, and it passes between the pincers with system is that squash type is connected; Cylinder piston rod is connected with cylinder impeller-hub on the crank throw, and crank throw is on anchor shaft is fixed on bearing perpendicular to bearing, and formation power is amplified lever construction thus.Though it can solve the vehicle anti-skid problem to a certain extent, there is following obvious defects in it: the one, and in the necessary continuous firing of glancing impact cylinder, consumes energy.The 2nd, pressure gas has much relations in braking force and cylinder and the cylinder, because the existence of various odjective causes often causes brake failure.
Summary of the invention
In order to overcome the defective that aforementioned prior art exists, it is a kind of to the anti-device that slips of hair line that the purpose of this utility model is to provide, and it can realize auto lock, brakes effectively.
The technical solution of the utility model is: to the anti-device that slips of hair line, comprise double acting hydraulic cylinder, be hinged on the pendulum plate on the brake bracket, on pendulum plate downside two fulcrums hinged double acting hydraulic cylinder of difference and the connecting rod mechanism Transmission, braking rail links to each other with connecting rod mechanism, it is characterized in that described connecting rod machine thing by connecting rod and forming with connecting rod and brake bracket pivotally attached double pendulum bar, described connecting rod mechanism Transmission be and connecting rod mechanism with put plate pivotally attached spring; Described pendulum plate is provided with swing arm and cooperates with the backstop that is fixed on the brake bracket of one side; Described fork one side is provided with fork and cooperates positive stop.
The utility model beneficial effect is: owing to be provided with self-locking mechanism, when glancing impact under forward and backward block effect, the spring center line tilts, a higher end promptly can not fall automatically near a side of pendulum plate, thereby realizes self-locking, this moment, oil cylinder can off-load; And braking force depends on spring, and the elastic force of spring can make the braking continuous and effective.
Description of drawings
Figure is the whole new structure scheme drawing of the utility model.
Among the figure: 1 flange of rail card, 2 rails, 3 wheels, 4 braking rail, 5 connecting rods, 6 forks, 7 springs, 8 pendulum plates, 9 bearing pins, 10 backstops, 11 brake brackets, 12 double acting hydraulic cylinders, 13 positive stops.
The specific embodiment
Following structure drawings and Examples are described further novel.
Figure is the whole new structure scheme drawing of the utility model.Dotted line is depicted as and alleviates the position among the figure, and solid line is depicted as retarder location.
To the anti-device that slips of hair line, comprise double acting hydraulic cylinder 12, be hinged on the pendulum plate 8 that approaches triangular form on the brake bracket 11 by bearing pin 9, pendulum plate hinged respectively double acting hydraulic cylinder 12 of 8 downsides, two fulcrums and connecting rod mechanism Transmission are on the spring 7, spring 7 one ends connect pendulum plate 8, and the other end connects connecting rod mechanism.Braking rail 4 links to each other with connecting rod mechanism, and connecting rod machine thing is reached by connecting rod 5 to be formed with connecting rod 5 and brake bracket 11 pivotally attached parallel double forks 6.Pendulum plate 8 is provided with swing arm and cooperates with the backstop 10 that is fixed on the brake bracket 11 of one side; Described fork 6 one sides are provided with and cooperate positive stop 13 with fork.
Its working process is: when the piston rod of double acting hydraulic cylinder 12 extends, promoting pendulum plate 8 clockwise rotates around bearing pin 9, spring 7 pressurizeds, promotion fork 6 rotates counterclockwise and drivening rod 5 moves with brake 4 parallel come-ups and to rail 2, when piston rod arrives range, when braking rail 4 and rail 2 backstops 10 are spacing, this moment, fork 6 was spacing by positive stop 13, and the line of centers of this spring tilts, side by pendulum plate 8 is high slightly, realize self-locking like this under the combined action of spring and block, double acting hydraulic cylinder 12 can off-load.When double acting hydraulic cylinder shrank, pendulum plate 8 rotated counterclockwise, and when spring 7 line of centerss near pendulum plate one side are lower than horizon, but just autobrake is alleviated.
The anti-slide device of said structure is that bilateral is installed and used on the line.
