Description
Technical field
The present invention relates to a kind of fastener that connects rail and railway roadbed, relate in particular to a kind of fastener structures of gauge adjustment.
Background technology
The Chinese city track traffic that starts from the nineties in last century is in fast development, and it is reported at present domesticly has 36 cities to design and the planning construction urban track traffic, and plan 96 rail lines of construction before and after 2015.And fastener is the critical piece that connects rail and railway roadbed in the track traffic design, and the track traffic fastener is of a great variety, mainly is made up of buckling piece, resilient sleeper-bearing and anchor connector three parts.Shape, kind and material and systemic-function, mode of connection, manufacturing difficulty or ease, construction and maintenance method and the financial cost etc. of each parts of composition fastener system are closely related.Fastener system is distinguished by different modes, and polytype is arranged, as: by distinguishing, be nonseparated rail fastening and separated rail fastening with the connected mode of railway roadbed; Mode by bearing horizontal force is distinguished, for shoulder block fastener and non-shoulder fastener are arranged; Press the fastening means of buckling piece and distinguish, for bolt fastener and non-bolt fastener are arranged.Although fastener is of a great variety, rely on the insulation rail of changing different model to adjust with regard to its gauge regulating power overwhelming majority apart from pad (being mainly high-elastic degree nylon material), in its use, there is following shortcoming:
(1) gauge pad compressive strength is not enough, the compression yield phenomenon often occurs in using at the scene.
(2) gauge pad flexural strength is not enough, diseases such as fracture, perk, bending occur in using at the scene.
(3) the pressure head area withheld on the gauge pad of spring is little, makes the gauge pad bear compressive strength in the area and can reach 155 MPa effectively withholding.It is reported that the producer that respectively produces reinforcing material all can't satisfy this requirement, this is to cause product one of reason of the low fracture of toughness of material, bending that toughness of material is high to occur.
(4) in train travelling process, owing to huge pressure, frequent vibration and friction, produce very big heat, make the deliquescing of gauge pad, reduced the product result of use widely.
(5) the gauge adjusting range be+8～-12mm, the gauge pad model that in track operation process, needs is more.
(6) the adjustment precision leans on model, the kind of gauge pad to decide, and desired precision is high more, and then corresponding gauge pad kind is many more, is unfavorable for the maintenance work in the operation process.
Summary of the invention
The present invention proposes to the problems referred to above; Purpose just provides a kind of structure simply, rationally; Can solve in the past gauge and regulate the gauge pad and the limited deficiency of adjustment amount of the multiple model of needs that exists, realize gauge regulate easy, flexibly, a kind of fastener structures of adjusting gauge accurately.
The technical scheme of technical solution problem of the present invention to achieve these goals is:
A kind of fastener structures of adjusting gauge; It comprises: iron chair, be located at the rail both sides relatively, and be fixed in left iron seat and the right iron seat on the iron chair, it is inboard and withhold left L shaped gauge pad and the right L shaped gauge pad on rail to be located at left and right iron seat; Iron chair places on the sleeper through backing plate; It is: L shaped two limits of described left and right L shaped gauge pad are different-thickness, and thickness differs 1 ~ 3mm, are equipped with the adjustment assembly on the adjacent adapting position of described left and right iron seat; This adjustment assembly mainly is made up of gauge locating piece, anchor bolt; It is that oval cone constitutes that described gauge locating piece has positive through hole outside by the middle part; Oval taper hole matches on this ellipse cone and the iron chair, and described gauge locating piece is fixed on the sleeper through described anchor bolt.
Described gauge locating piece adopts the middle part to have the outside gauge adjusting block for oval cone of eccentric through-hole when adjustment and substitutes.
Described adjustment assembly also has packing ring.
Described anchor bolt links to each other with sleeper through pre-buried insulation sleeve in sleeper.
The present invention compared with prior art has advantage and effect:
(1) gauge locating piece and gauge adjusting block material are metal material, and relatively only the L shaped gauge pad intensity with nylon material is high, helps keeping reasonable gauge.
(2) because the oval cone of the outside employing of gauge locating piece and gauge adjusting block; Corresponding with oval taper hole on the iron chair; Can realize the slitless connection between iron chair and gauge locating piece or gauge adjusting block through the buckle press of anchor bolt; Effectively realize the globality of iron chair, reduce the appearance of error.
(3) the gauge adjusting range be+8～-12mm, satisfy the requirement of " rail track is repaired rule ".
(4) the adjustment accessory only needs gauge adjusting block, and model is single, and cooperates the L shaped gauge pad of adjustment gauge constant, is the adjustment of single position, need not to be equipped with the L shaped gauge pad of multiple model again, is convenient to the maintenance operation.
(5) gauge adjustment error is little, and its ability can reach+0.5～-0.5mm.
(6) the present invention adjust mode easy, save time flexibly, accurately, easy operating.
