Abstract
The utility model relates to a rail vehicle core pin with pull node separator, set up in the base at position sleeve rear portion including the position sleeve, through the location pull rod, the position sleeve front end has and draws internal screw -thread fit's external screw thread, is provided with slidable direction pressure head in the position sleeve, and direction pressure head front end is suitable for the outer terminal surface that supports the towing pin, is fixed with the hydro -cylinder on the base, and the rear end of direction pressure head is aimed at to the piston of hydro -cylinder, and separator still has a hydraulic pump, and the external hydraulic service end of hydraulic pump is through the hydraulic pressure input of high pressure fuel pipe connection hydro -cylinder. During the use, twisting to pull the body with the position sleeve front end, then installation location pull rod, direction pressure head, hydro -cylinder and base in proper order, connecting the hydraulic pump after that, the switch on makes the direction pressure head push away the towing pin forward through driving oil cylinder, under reaction force's effect, will do all can the transmission through the location pull rod and give and pull the body, makes and pulling the body from towing pin separation.
Description
Technical field
The utility model relates to rail vehicle centrepin and traction node separator, belongs to rail truck and manufactures maintenance craft technical field.
Background technology
Domestic novel 25T type passenger vehicle draw-gear is the product structure introducing Europe, centrepin (towing pin) is cone match with traction node (traction body), being easy to that adhesion causes cannot natural separation, node is caused to pull damage, artificial measures is relied on to push up pressure or adopt cutting and separating, the large cost height cycle length of working strength and inefficiency.Also there is no the instrument that a kind of 25T of being exclusively used in type passenger vehicle centrepin is separated with traction node at present.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the above-mentioned shortcoming of prior art, provides a kind of rail vehicle centrepin and traction node separator.
In order to solve above technical problem, the rail vehicle centrepin that the utility model provides and traction node separator, it is characterized in that: comprise positioning sleeve, the base at positioning sleeve rear portion is arranged at by positioning tie bar, described positioning sleeve front end has the external screw thread with traction body screw-internal thread fit, the pressure head that slidably leads is provided with in positioning sleeve, guiding pressure head front end is suitable for the outer face propping up towing pin, described base is fixed with oil cylinder, the rear end of the piston alignment guide pressure head of oil cylinder, separator also has hydraulic pump, the hydraulic pressure output of hydraulic pump connects the hydraulic pressure input of oil cylinder by high-pressure oil pipe.
The utility model also has following improvement:
1, described hydraulic pump is Mini electric hydraulic pump.
2, described oil cylinder is miniature aluminum alloy hollow oil cylinder.
During use, positioning sleeve front end is screwed into traction body, then positioning tie bar, guiding pressure head, oil cylinder and base are installed successively, then connecting fluid press pump, switching on power, making guiding pressure head push away towing pin forward, under the effect of reaction force by driving oil cylinder, by positioning tie bar, power is passed to traction body, traction body is separated from towing pin.
Fast traction body can be separated from towing pin by the utility model, easy to operate, reduce the labour intensity of workman, improve operating efficiency.
Utility model beneficial effect is as follows:
1, digest and assimilate external key technology, improve the maintenance manufacturing capacity of self;
2, meet production maintenance and use requirement, ensure that the quality of product is used in maintenance.
3, autonomous Design completely, and according to the research approach of production domesticization, significantly reduce manufacturing cost.
4, the key interface of autonomous Design meets domestic instructions for use, is simple and easy to use.
