专利说明:
one The invention relates to an upper rail structure, in particular to electrically insulating butt joints of rails. Fitted electrical insulating butt joint of rails containing side plates with holes for fasteners located on the sides of the rails, made of steel with plastic coating 1J However, the known device has an insufficiently high resistance to the longitudinal shift of the plates relative to the rails, especially when they are shortened in case of negative temperature. The purpose of the invention is to increase reliability by increasing the longitudinal resistance to shear of linings relative to rails when shortening the latter. The goal is achieved by the fact that in an electrically insulating butt joint of rails, contained on the sides of the rails. lining with holes for fasteners made of steel with plastic coating on the plastic coating of each lining in the area of interaction with the rails there are vertical protrusions with a face located at an acute angle to the lateral surface of the rails, directed by its top towards the butt gap, and these protrusions are mirror symmetrically relative to the latter. In addition, wear-resistant or metallic granules are distributed in the plastic lining, the hardness of which is greater than the hardness of the rails.

Claims (2) [1] Fig, 1 shows the device, a cross-section along the lining; in fig. 2 is an overlay, viewed from the side surface of the rail; in FIG. 3 is the same, seen from the outer side of the device j in FIG. - section A-A in FIG. in fig. 5 is a section BB in FIG. 2, in FIG. 6 is a section B-B in FIG. 5, FIG. 7, a projection of the plastic covering of the lining when it contacts the side surface of the rail before the mounting tightening of the bolts, top view; FIG. 8 is the same after mounting the bolts. The rail 1 consists of a head 2 and a sole 3 (FIG. 1). Between the rail head 2 and its sole 3, surfaces of the rail 4 section 4 are made, to which the surfaces of the connecting plate 5 placed on both sides of the rail 1 are attached. The latter is fastened with threaded bolts 6 with nuts 7. The bolts 6 pass through the rails in the through holes and through connecting plates 5o. The mounting bolts 6 are secured by means of nuts 7 interacting with washers 8. The connecting plate 5 is made of a steel element 9 with a plastic coating 1.0 (figs, 1, and 5). At the same time, it is important that the steel element 9 in the zone of the through-hole 11 also has a plastic coating 10 in order to ensure the electrical insulation of the connecting plate 5 from the rails .1; For the coating of the steel element 9, polylautine lactam is preferred, since this plastic has good adhesion properties, the ability to regain form and cold resistance On the outer side (Fig. 3 and C) of the connecting plate 5 there is a hole 12 with a large diameter. 8. The surfaces of the connecting plate 5, which are adjacent to the surface of the rail profile 1, are made in the form of protrusions 13 ° with mutual clearance. The faces of the rail profile k adjacent to the surfaces of the rail profile 1 are 14 protrusions 13 located under the base eye angle to the side surface 4 of the profile rail 1 (FIGS. 6-8). Each specified angle of faces k is directed by its top towards the joint gap (indicated in FIG. 6 by line 15) Tie. the projections 13 are mirror symmetrical. Face 14 has a linear contact with the surfaces of profile 4 of rail 1 in an unstressed state, i.e. when mounting bolts 6 are loose or. tightened only a little (Fig. 7). If fastening bolts 6 are tightened to. the standard value, the gap between the side surface of the profile 4 and the face has k connecting pad 5 decreases. In this case, a build-up 16 is formed, which, when subjected to a force in the direction of arrow G (Figs. 7 and 8), i.e., in the direction of the compressive longitudinal force in rail 1, is drawn along arrow D into the gap between the face l of the protrusion 13 and the lateral the surface of the profile k of the rail 1. As a result, the pressing of the connecting plates 5 to the rail 1 in the direction of the arrow F, increases. Due to the shape and mirror-symmetrical arrangement of the projections 13 relative to the line 15 of the joint gap, the resistance of the docking plate 5 increases in proportion to the longitudinal. shear rails during shortening of the latter, especially at negative temperatures, causing them to compress in the direction of arrow G, due to the placement of wear-resistant metal pranules in the plastic coating 10 and above all in the projections 13 (the material of the granules is much harder than the material of the rail) the closure of the plates 5 with the surfaces of the profile k of the rail 1. In this case, the tip of the protrusion 13 can be considered as a shearing knife, the material of which (metal granules) cuts into the material of the rail, as a result an increase in the reliability of the device is achieved, first of all when it is working in a continuous way, and in winter. Claim 1. An electrically insulating butt joint of rails containing side plates of rails with openings for fasteners made of steel with a plastic coating, is characterized in that each lining in the interaction zone with the rails is made vertical protrusions with a face located at an acute angle to the side surface of the rails, on systematic way its apex toward the butt gap, and said projections are arranged mirror sinmetrimno relative to the last .. [2] 2. A compound according to claim 1, characterized in that wear-resistant or metallic glue is distributed in the plastic coating of the lining zeros, the hardness of which is greater than the hardness of the rails.
