Abstract
The invention discloses a flexible ejection head for a wheel-pair wheel returning machine, comprising a fixing block, a flexible ejection head and a connecting device, wherein the connecting end of the fixing block and the flexible ejection head is of an outward-convex spherical face; the connecting end of the flexible ejection head and the fixing block is a concave face which is concave inwards and is adapted to the spherical face of the connecting end of the fixing block; the fixing block and the flexible ejection head are contacted through the spherical face and the concave face; and the connecting device is used for movably connecting the fixing block with the flexible ejection head. The flexible ejection head guarantees that the force application direction of a piston rod is parallel to the central axis of a car axle, thereby achieving the convenient dismantling.
Description
Technical field
The present invention relates to take turns to moving back the pressure head that is used for the piston rod end of turbine.
Background technology
Wheel is to being the running part of rolling stock, and it mainly is comprised of an axletree and two wheels, and for guaranteeing the safe operation of rolling stock, two wheels of these parts all are installed in the two ends of axletree in the mode of interference fit.Behind vehicle operating certain hour or mileage, must enter factory's maintenance to it, and the first working procedure of maintenance is that two wheels are decomposed out from the axletree two ends, namely moves back the wheel operation.This operation is normally moved back turbine at the rolling stock of special use and is finished.When moving back the wheel operation, to take turns first to send into move back turbine move back the wheel station, be arranged on the cylinder piston rod that moves back on the turbine and withstand axletree one end, the wheel hub position of wheel abuts on the load boss that moves back the stressed crossbeam of turbine, the hydraulic cylinder fuel feeding, after piston rod headed on axletree operation LAP, the wheel that can finish an end moved back the work of unloading.Wheel in moving back the process of unloading, the application of force direction that requires hydraulic cylinder piston rod all the time with axletree axial line keeping parallelism, otherwise can greatly increase the power of unloading of moving back, cause wheel to move back and unload difficulty, even cause the axle shaft end pier thick and can't continue to use.
Summary of the invention
Purpose of the present invention solves exactly wheel and is difficult to be consistent with axle centerline to moving back turbine piston rod application of force direction, causes the problem of unloading difficulty even damage of moving back.
For addressing the above problem, the technical solution used in the present invention is: be used for wheel to moving back the flexibility top of turbine, it is characterized in that it comprises the fixed block fixing with moving back turbine hydraulic cylinder piston rod end section, the jockey of the flexibility top that is connected with fixed block and connection fixing block and flexible top, described fixed block with flexibility top link be outwardly sphere, what described flexibility came directly towards is to inwardly concave the recessed face suitable with the link sphere of fixed block with the fixed block link, fixed block contacts with recessed face by sphere with flexible top, and jockey is flexibly connected fixed block and flexible top.
The center of described fixed block and flexible top is provided with axially extending bore, has telescopic toply in the through hole, and through hole and push rod profile are suitable, and push rod and flexibility come directly towards between the hole wall of central through hole gapped.Described jockey comprises fixed cover and screw, described fixed block and junction, flexible top are sleeved in the fixed cover cavity, screw is connected and fixed cover and flexible top, fixed cover and fixed block link are provided with the annular boss that stretches out to the fixed cover center, the corresponding position of fixed block is provided with the annular groove that cooperates with it, and the boss of fixed cover is positioned at the annular groove realization fixed cover of fixed block and the flexible connection of fixed block.Be provided with flat rubber pad and circumferential rubber blanket in the annular groove of described fixed block, make annular groove and boss flexible contact.Described top push rod, sleeve and the spring of comprising, described sleeve set is on push rod, the non-operative end thread connection slotted nut of push rod, be provided with the split pin by push rod in the open slot of slotted nut, be set with two packing rings on the push rod between sleeve and the slotted nut, spring housing is contained on the push rod between two packing rings.
Beneficial effect of the present invention is: when flexibility top is expressed to the right wheel face of train wheel, when piston rod and the right wheel shaft of wheel not point-blank the time, flexible top can be rotated around fixed block under the effect of extruding force, reach and guarantee that the flexible top end surface fits with the right wheel end face of wheel all the time, the direction of extrusion to piston rod is revised, guarantee piston rod application of force direction all the time with axletree axial line keeping parallelism, realize for convenience detach.
