Description
Technical field
The utility model belongs to railway classification yard speed governing gravity type boat davit retarder, particularly pneumatic or hydraulic pressure gravity type boat davit retarder.
Background technology
Present pneumatic, the hydraulic pressure gravity type boat davit retarder that uses, all adopt cylinder or oil cylinder directly to promote the parallelogram transmission device and drive the braking rail action, realization is to vehicle braked and alleviation, and the selection of its retarder cylinder or cylinder thrust is mainly considered the locking force of retarder glancing impact and repeated braking force.Merely from satisfying the angle of retarder action, only need just passable than the cylinder or the oil cylinder of low thrust, but existing retarder is owing to adopt cylinder or oil cylinder directly to promote, so must select the locking force that cylinder or oil cylinder than high thrust could satisfy glancing impact and repeat required braking force, cause the volume of drive part big, energy consumption is higher.In addition, because existing pneumatic or hydraulic pressure retarder employing cylinder or the direct locking of oil cylinder, so under locking states, still can produce the cylinder phenomenon of " kowtowing ", cause the deficiency of retarder braking potential, also can produce direct physical shock at glancing impact simultaneously to cylinder or oil cylinder.Existing another problem of the direct locking of cylinder or oil cylinder is: glancing impact cylinder or in-oil cylinder medium are in the pressure mode of operation all the time, so need bleed off the gas or the oil of cylinder or oil cylinder brake side when alleviating earlier, and then to alleviating side input pressure gas or oil, cause alleviation speed slow, control accuracy is low.
Summary of the invention
The utility model has solved " kowtowing " phenomenon of retarder glancing impact cylinder in the background technology, the technical matters that energy consumption is relatively large.
Technical solution of the present utility model is:
Pneumatic or the hydraulic pressure retarder of the gravity type boat davit that is provided comprises brake clamp, promotes the parallel-crank mechanism and the driving cylinder of this brake clamp.Improvements of the present utility model are to be provided with the three-link mechanism that a piston rod by described driving cylinder, first connecting rod and second connecting rod are formed, one end of the piston rod of wherein said driving cylinder and first connecting rod and an end of second connecting rod are hinged, cranking arm of second end of first connecting rod and described parallel-crank mechanism is hinged, and second end and the pedestal of second connecting rod join.Cylinder or oil cylinder promote parallel-crank mechanism indirectly by three-link mechanism and drive the braking rail action, and above-mentioned three-link mechanism can amplify the thrust of cylinder or oil cylinder, thereby can use cylinder or oil cylinder than low thrust to produce bigger braking force.Because three-link mechanism can realize mechanical latching, thereby eliminated " kowtow " phenomenon and avoided the retarder body that the direct mechanical of cylinder or oil cylinder is impacted of cylinder.
Concrete technical solution is as follows:
Pneumatic or the hydraulic pressure retarder of a kind of gravity type boat davit, comprise brake clamp, promote the parallel-crank mechanism and the driving cylinder 14 of this brake clamp, it is characterized in that being provided with the three-link mechanism 2 that a piston rod 9 by described driving cylinder, first connecting rod 8 and second connecting rod 10,22 or 23 are formed, the piston rod 9 of wherein said driving cylinder is hinged with an end of an end of first connecting rod 8 and second connecting rod 10,22 or 23, cranking arm of second end of first connecting rod 8 and described parallel-crank mechanism is 7 hinged, and second connecting rod 10,22 or 23 second end and pedestal join.
The pendulum angle β of above-mentioned driving cylinder 14 can be 0～10 °, and the first connecting rod 8 of described three-link mechanism can be 0～10 ° in soil with the second end line of second connecting rod 10,22 or 23 and the angle α of first connecting rod 8 under locking states.
Second end of the second connecting rod 10 of above-mentioned three-link mechanism is the best to be hinged on the pedestal 11.
When the second connecting rod of above-mentioned three-link mechanism adopted the roller 22 that can roll on a constant inclined surface, the pendulum angle β of driving cylinder 14 was good with 0 °.
The second connecting rod of above-mentioned three-link mechanism adopt one can be when the slide block 23 that fixedly slides in the chute, the pendulum angle β of driving cylinder 14 is good with 0 ° also.
The utlity model has following advantage:
The three-link mechanism that the utility model is set up has amplifying power, thereby has reduced the thrust of cylinder or oil cylinder, has reduced the volume and the energy consumption of cylinder or oil cylinder; Since can carry out mechanical locking, thereby improve the braking potential of retarder widely and repeated braking potential, simultaneously, owing to avoided the retarder body to cylinder or the direct physical shock that produces of oil cylinder, so improved the service life of equipment.In addition, because the utility model can carry out mechanical locking at glancing impact, so after retarder brake puts locking in place, just can bleed off braking usefulness gas or oil, when receiving the alleviation order, can import gas or oil to the alleviation side of cylinder or oil cylinder immediately, thereby reduced remission time, improved control accuracy.
