Abstract
The utility model discloses a nondestructive dismounting device for a side rolling resistant torsion bar of a light rail vehicle. The utility model is characterized in that the nondestructive dismounting device comprises a mechanism, wherein a screw rod and a double-side wedge block of the mechanism are connected to form an integrity; a round nut is matched with the screw rod; a handlebar is inserted in the hole of the round nut; a locating support is arranged on the upper surface of the round nut; an opening of the locating support aims at a bumping at the lower part of a vehicle body; a stop iron is fixedly connected with a bottom frame of the vehicle body in a space connected by the lower part of the bottom frame of the vehicle body and the side rolling resistant torsion bar; and a choker block is arranged between the stop iron and the locating support. The nondestructive dismounting device has the positive effects that the screw rod is used to drive the double-side wedge block to move downwards, so that a vertical acting force is converted into a horizontal thrust; therefore, the side rolling resistant torsion bar can be separated from the vehicle body without damaging the associated spare part.
Description
Technical field
The utility model belongs to trolley coach mounting technology field, relates to the provision for disengagement of light rail vehicle anti-side rolling torsion rod.
Background technology
At present, light rail vehicle anti-side rolling torsion rod and car body bottom are that the taper hole of taper pin and tapered hub closely cooperates, and in light rail vehicle assembling, maintenance, do not have special-purpose anti-side rolling torsion rod extracting tool.Because the narrow space that the underframe bottom of light rail car is connected with anti-side rolling torsion rod, instrument can't enter, and uses existing instrument can damage car body and axle sleeve and some parts that is mutually related.
The utility model content
The purpose of this utility model provides a kind of light rail vehicle anti-side rolling torsion rod provision for disengagement that is used for, and solves light rail vehicle anti-side rolling torsion rod nondestructive demounting problem in assembling, maintenance, reaches and do not damage related part purpose in unloading process.
For achieving the above object, the utility model provides a kind of light rail vehicle anti-side rolling torsion rod provision for disengagement that is used for, it is characterized in that: comprise the mechanism that screw rod and two-sided wedge connect as one, round nut cooperates with screw rod, handlebar is inserted in the hole of round nut, be provided with the location holder above the round nut, the gap of location holder is aimed at the projection of car body bottom, in car body underframe bottom and space that anti-side rolling torsion rod is connected and with the car body underframe, be fixedly connected with buting iron, be provided with choker block between buting iron and the location holder.
Good effect of the present utility model is: utilize screw rod to drive two-sided wedge and move down, convert the vertical direction active force to horizontal direction thrust, realize not damaging in the unloading process related part anti-side rolling torsion rod is separated with car body.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
With reference to accompanying drawing, the taper pin 10 of anti-side rolling torsion rod 9 is the structures that closely cooperate with the taper trepanning 11 of light rail car body underframe 12 bottoms.The handlebar 1 of this provision for disengagement is screwed operation in the hole by connecting axle 2 insertion round nuts 3.Round nut 3 is threaded engagement with screw rod 4, and when round nut 3 rotated, screw rod 4 was done rectilinear motion.Screw rod 4 connects as one with two-sided wedge 5, and screw rod 4 moves downward and drives two-sided wedge 5 simultaneously and move downward.5 one faces of two-sided wedge lean against on the buting iron 6, and another face withstands on the termination of taper pin 10.Buting iron 6 kept motionless when two-sided wedge 5 moved down, and taper pin 10 is subjected to the thrust that two-sided wedge 5 produces, and displacement vertically breaks away from from taper trepanning 11.
During use, to locate holder 8 and be inserted in screw rod 4, the gap of location holder 8 is aimed at the projection of light rail car body underframe 12 bottoms, a face of two-sided wedge 5 withstands on the termination of taper pin 10, another face leans against on the buting iron 6, in car body underframe 12 bottoms that are fixed on the light rail car on the buting iron 6 and the space that anti-side rolling torsion rod is connected, and put into choker block 7 at the buting iron 6 and the gap location of location holder 8.More than effect is to stop round nut 3 to top offset, makes it and can only rotate; And screw rod 4 and two-sided wedge 5 can only be done rectilinear motion.By screwing handlebar 1, mild pulls down taper pin 10 from taper trepanning 11, realizes not damaging in the unloading process related part anti-side rolling torsion rod is separated with car body.
