Description

4 and 5, located at the ends of the cast part of the guardrail, are symmetrically relative. in terms of the point of application of the press. The cross is bent by the force of the pres-5s by an amount determined by the tab. face depending on the amount of wear, type and mark of the cross.

The invention relates to railway transport and concerns methods of repairing elements of the upper structure of the track, namely, turnouts of turnouts.

The purpose of the invention is to increase the durability and reliability of operation.

Figure 1 shows the cross in

bending process, side view; in Fig. 2, the bent crosspiece is fixed to the same, in the course of the mechanical treatment of the 10 supporting base 6, the metalworking; using a detachable joints using inventory pads .7 of various thicknesses and a metal-cutting tool 8-15 by a cutter, the metal is removed above level B-B. The surface treatment of the rolls is carried out in compliance with the established transverse slope. When laying the repaired cross, direction B, to the bottom of the cross, 20 into the path below its cross section, the maximum wear and cross section of the bar should be fitted with gaskets of the appropriate thickness to eliminate the leakiness of the cross to the crossbar, due to the cross that was repaired from the polluter 1 repair - copy, determine its vertical wear in the zone of maximum wear in section A-A, located in the area where the core width is 20-40 mm. Then the spider is mounted on the frame 2 hydraulic press and in i

AA make a press effort of 50-100 tons, depending on the type of cross. The crosspiece rests against the surface of the Katani in the fixedly curved base of the cruciate of the cruciform on the frame of the hydraulic press.

4 and 5, located at the ends of the cast part of the guardrail, are symmetrically relative. in terms of the point of application of the press. The cross is flexed by the force of the press by an amount determined by the tab. face depending on the amount of wear, type and mark of the cross.

METHOD FOR REPAIR OF ARROW CROSSES, consisting in machining of the rolling surface, different? In order to increase the durability and reliability of work, before machining, the crosspiece is bent until the levels of the skating surface at its ends and in the zone of maximum wear are bent (after removing the bending load), and the skating surface located above the specified level is machined. μ ——— / —.---------- SU. ,,. 1239185 Figure 1
