SU1254034A1 - Apparatus for heating rolling surface of wheel pairs - Google Patents

Description

112

The invention relates to the heating of worn wheelsets of rolling stock and can be used in railway transport repair plants.

The aim of the invention is to expand the functional possibilities while maintaining the uniformity of heating.

Figure 1 shows the proposed device in the plan; figure 2 is the same, side view; on fig.Z - the same, front view; figure 4 - the relative position of the inductor with rollers relative to the treated surfaces

The device consists of a power source 1, a stand 2 for mounting and rotating a wheel pair, a rotary mechanism 3 with pushers 4 and a track 5.

The stand has driving support rollers 6, a reduction gear 7 with an electric motor 8 and non-driving support rollers 9, which are capable of moving in a vertical plane by means of a lifting mechanism 10, which presses the wheel set to the stop rollers 11 attached to it. bracket 12.

The device is equipped with a mechanism 13 of the reversed rotation of the stand in a horizontal plane at an angle relative to the center of rotation 14, which ensures a uniform gap between the heated surface of the wheels and the transmitter 15,

The reverse rotation mechanism 13 rotates the stand until both thrust rollers II touch the Katani surface of the wheelset.

The mechanism 13 of the reversing rotation consists of a thrust bearing 16, supports 17 and a screw assembly. Including the nut 18, the support 19, the screw 20 and connected through a gearbox 21 to the engine 22.

For a constant installation of wheel sets to one of the sides of the supporting drive and non-drive rollers, the axles 23, which interconnect only the drive rollers and only the non-drive rollers, are mounted with an inclination

An inclined path 4 is installed to feed the wheelsets to the swivel mechanism, and a draft 24 is used to remove harmful emissions.

5 The device operates as follows.

Wheelsets are fed along an inclined path to a swivel mechanism that turns the wheelset

 by 90 °.

When lowering the non-driving support rollers 9 to the lowest position, the pushers 4 feed the wheelset to the driven support rollers 6, at this moment the lifting mechanism 10 lifts it up to one of the P. hard rollers. Next, the reversing mechanism of the stand 13 rotates the stand until the surfaces touch the wheels simultaneously with two thrust rollers 11, while due to the inclination of the axles 23, the wheel pair is pressed permanently to one side 6 of the support roller, which provides orientation-wheel pairs with different distances Between the wheels.

After the orientation of the wheelset has been completed, the rotation mechanism is turned on, the power source is heated with a chain to reduce the hardness of the worn wheel hardness layer. by 180 °.

Pushers 4 podazot wheelset again on the drive support rollers,

0 and further, similarly to the processing of the first wheel, the second wheel is processed.

Then the wheelset rolls back again onto the rotary mechanism 3, which rotates it, by 90 °, and the pushers 4 feed it for further processing.

The proposed device allows the processing of wheels of pairs

50 different sizes, alternately both wheels, while ensuring the stability of heating.
