SU10457A1 - A device for recording the profile of the tires - Google Patents

Description

The present invention aims to create savings in the length of service of the tires of wheel ramps in railway facilities by applying, after the wear of the rock, not only its profile, but also the roll circumference, which determines the skate eccentricity and determines the minimum and maximum radii .;

In FIG. 1 shows the installation of the device on the ramp; fng 2- longitudinal section of the device; FIG. 3- the same, top view with partial section; FIG. 4-record profiles; fig 5 is a side view of the device when processing a ramp on a machine.

The device consists of two symmetrically placed one above the other holders 7 (Fig. 3), separated by partitions 9 and fastened with screws 8. In the holes of one of the partitions 9 are rods 14, which are under the action of springs 17. In the slots of the square guide rods 14 16 knurled wheels 15 are placed on the axle 16, and on the cylindrical end of the rods 14 there are fitted dies 11 with needles 12 fastened with nuts 19. Dies 11 when pressed on the wheels 15 will longitudinally move in slots 10 cages 7. In the same slots 10 close with nuts 19 placed loosely ne Other dies 11 with needles 12, moving along the rods 14. The sleeves 7 are mounted on the rods 5 and 20 (Fig. 1) fixed on the frame 4, the latter being installed in the centers of the slope 1 with screws 2. In addition to the device, the board 21 is supposed (Fig 2) with a sheet of paper 22, slid into the holder 23, mounted on the frame 4. For applying REMOVED pricked on the board 21 of the banding profile with the aim of turning the latter on the machine, stand 27 is installed (Fig. 5) with a retractable holder 28 and an ANGULAR lever 30 pivotally fixed on the axis 29, whose short arm is connected by a TOWER 13 with the axis 33 of the ratchet wheel of the screw of the supor and the long one is equipped with a needle with a key 31. For using this device, frame 4 (Fig. 1) ) screws 2, installed in the centers of the axis of the slope. On the rods 5 and 20 crawls}, gnami 6 strengthens the left and npaBjTO holders 7 with the needles 12 up or, instead, with pencils, having previously moved the dies 11 until the needles touch 12. Over the ferrule 7 they fix the ferrule 23 on the frame 4, the latter can be folded back hinged to insert the board 21 with a sheet of paper 22 into it.

The loaded frame 4 hands lead to a horizontal position on the ramp 1, located on the rails (Fig. 1) and carefully roll it to about one turn. The needles 12 or pencils (Fig. 3), due to the pressure of the wheels 17 on the profile of the slope by the springs 17, trace traces of the radii of the katani circles on the paper, according to the positions of the extreme points of which the maximum and minimum radii are found.

In view of the fact that several rods are located along the profile of the slope, the same number of skating circles are obtained and if in addition to this holder 7 to be moved to the rods 5 and 20, then you can find exactly the worn surface of the Katani of the whole bandage with all the potholes obtained during service.

If we supplement the device with a template of a normal bandage profile and lay it on the board 21 so that it fits into the profile of the points of the smallest radii, then using pointers 25 and 26 you can find a valid new profile of the slope.

The skates' surfaces recorded by this device in the wheeled park on sheets of paper, even before entering the workshops, will make it possible to take into account the presence of sets of the required diameter and point to small ones that are sent to replace the tires.

Ramps accompanied in a wheel shop with a profile applied to the paper can be machined on the wheel machines if the profile with the board 21 is placed in a pull-out box 28 (Fig. 5) of the rack 27 fixed on the fixed part of the machine's support. The distance of the cutting edge of the cutter fixed on the suporta, to the needle must be strictly defined, which is observed if the cutter is installed on the bracket 35 (template) applied to the machined part of the suporta and the cutting edge of the incisor. The longitudinal supports are set so that the cutting edges of the incisors fit exactly against the ridge of the flange and mark K (Fig. 3), filled with the core on the wheel pair during its marking against the wheel 15 and put the boards 21 with profiles in both 28 so that the needle is angular levers 30 hundred la against the cross (-) -) profile 12i. The key 31 is advanced by the value of the maximum permissible cutting depth.

The subject of the patent.

1. An instrument for recording a profile of wheel ramps, characterized by the fact that in the holders 7 consisting of two figured plates attached to the partitions 9 there are rods 14, which are under the action of springs 17 and bearing on one end x 16 wheels 15, and at the other end nuts 19, located between movable 10 holes 11, fitted with needles 12, which sleeves 7 are mounted on rods 5 and 20, mounted on frame 4, mounted on centers on wheel axle 1.

2. With the use described in item 1 of the device, for removing the profile of the bandage, the board 21 with a sheet of paper 22, inserted into the holder 23, reinforced on.

3. Application of the bandage profile that has been punctured on the board 21 for turning the bandage on the machine, characterized in that the boards 21 lie on the uprights of the racks 27 located on the fixed bases of the suports, under the needles fixed on the long arm 30 of the angle / lever, which is rotatable mounted on an axle 29 and whose short arm is connected by a pull 32 with an axle 33 pawns turning the screw of the longitudinal suporort.
