Described the 3rd rail supporting component 1 is made up of sub-fastener 11 and mother buckle 12, is used to the 3rd rail to provide support.
Described sub-fastener 11 is that steel casting is one-body molded, and this sub-fastener is formed " L " shape by the upright shoulder 112 of lateral piece 111, sub-fastener, the horizontal shoulder 113 of sub-fastener and constructed, and described lateral piece end has and is used for and the sub-fastener assembly opening 1110 of mother buckle stack-mounted; Described lateral piece is the straight horizontal plate, the both sides of sub-fastener have convex ridge, this convex ridge plays the convex edge that forms edge sealing from the lateral piece port through the upright shoulder of sub-fastener until the horizontal shoulder of sub-fastener, not only the lateral piece end has formed the sliding part that combines with mother buckle fitting recess coupling thus, but also can effectively strengthen the bulk strength of these parts.
Described mother buckle 12 is that steel casting is one-body molded, this mother buckle is made of vertical plate part 121 and the horizontal portion 122 of holding, the described horizontal portion of holding has the horizontal shoulder 1223 of mother buckle, described vertical plate part is vertical mutually with the horizontal portion of holding, mother buckle is packed on the mounted base 210 of support upper body by this vertical plate part, be illustrated as three-point fix and install, referring to Fig. 3; The described horizontal portion of holding has horizontal top plate 1221, form the upright shoulder 1222 of mother buckle between the horizontal shoulder 1223 of this horizontal top plate and mother buckle, be extended down to vertical plate part by the horizontal shoulder of mother buckle and form horizonal base plate 1224, form fastener container cavity 1225 between horizonal base plate and the horizontal top plate, the vertical plate part of mother buckle is not provided with the positioning structure and only is responsible for fixing assembling thus, the horizontal fastener container cavity that holds portion of mother buckle forms the hollow out structure, can effectively avoid causing because of parts expand with heat and contract with cold the accident of " jam "; Moreover it also can make the parts lightweight, and the locknut of fastener also can take this to hide oneself, and horizonal base plate also forms further the horizontal shoulder of mother buckle and the upright shoulder of mother buckle and supports; Has the mother buckle assembly opening 1210 that combines with sub-fastener assembly opening coupling on the described horizontal top plate, these horizontal top plate both sides have top board convex ridge 12211,12211 ' and form mother buckle fitting recess 12210, this mother buckle fitting recess becomes to be slidingly installed with the lateral piece end, sub-thus fastener installs by fastener 10 by the mother buckle fitting recess, this fastener includes but not limited to binding bolt and locknut mode as shown in the figure, but actv. solves sub-fastener and the loosening easily problem of mother buckle fastening position.
The upright shoulder of described mother buckle is suitable with the upright shoulder height degree b of sub-fastener, and the geometrical extension a of horizontal shoulder of mother buckle and the horizontal shoulder of sub-fastener is suitable; Mother buckle slightly is wider than sub-fastener, with the sub-fastener of support.
Mother buckle and sub-fastener fasten to have formed and hold the track chamber 16 that the 3rd rail passes through thus, form track jaw 160 between horizontal shoulder of sub-fastener and the horizontal shoulder of mother buckle; Sub-fastener width e is set to 4/9 or 5/9 or 1/3 or 2/3 of track chamber width; Contact surface with effective minimizing the 3rd rail and track chamber; Track chamber width is the upright distance of takeing between the upright shoulder of sub-fastener of mother buckle.
On upright shoulder of mother buckle and the upright shoulder of sub-fastener, and track contact assembly opening (not shown) is set respectively on horizontal shoulder of sub-fastener and the horizontal shoulder of mother buckle, with attachment rail contact 13; Described track contact 13 is made of cap body 131 and assembling bolt 132, described cap body constitutes the semi-cylindrical structure by cap body bottom surface 1310 and cap body periphery 1311, this assembling bolt middle position is in this cap body bottom surface 1310, and cap body bottom surface length is 1 times of cap body bottom width or 1.5 times or 2 times or 2.5 times; Cap body bottom width is 1/3 of the horizontal shoulder elongation of sub-fastener or mother buckle a; Assembling bolt diameter is 1/2 of a cap body bottom width; Cap body bottom width is less than the upright shoulder of mother buckle (or the upright shoulder of sub-fastener) height b, Gou Zao track contact can guarantee that the contact surface of it and the 3rd rail is very little thus, can guarantee that again the track contact is installed in son, solid durable on the mother buckle, difficult drop-off, particularly the track contact of this structure is simple in structure, compatibility is good, as " drawing pin ", can become the industrialization gauge member, easy for installation, arbitrarily " nail " is at the predeterminated position in track chamber, allow the 3rd rail contact with not formation of track chamber face, but linear contact, thereby can effectively solve the such problem that exists in the prior art: the 3rd rail and track chamber contact surface are bigger, and causing expands with heat and contract with cold causes the 3rd rail clip resistance phenomenon.
The track contact is that commercially available nylon material or PTFE anti-wear material is one-body molded.
