Abstract
The utility model provides a temporary beam rail fastener for construction, which is fixed at two sides of the railway track to locate the railway track to ensure accurate position of the railway track; the temporary beam rail fastener is composed of a pinch plate locating support, a beam side rib plate, an adjusting pinch plate, a lock washer and a locating bolt; the pinch plate locating support is connected with the beam side rib plate, the adjusting pinch plate is connected on the beam side rib plate by the locating bolt and the lock washer, and one end of the adjusting pinch plate is leaned against to the rail branch at the lower part of the rail, and the other end is pressed on the beam side rib plate. In the utility model, the rail fastener is tightly and firmly connected with the beam, the novel rail fastener adopts inner and outer adjusting pinch plates and the lock washer and other parts, so as to lead the fastener and the beam to be connected tightly and solves the technical problems that the fastener and the beam are connected infirmly, the circuit insulation is unreliable, and the side-to-side adjustment quantity that the pinch plate finely adjusts an iron base is low.
Description
Technical field
The utility model belongs to the location technology that guarantees the rail tram on railroad track the accessory technical field, particularly railroad track.
Background technology
The effect of rail fastening is the tram that keeps rail, prevent that rail from length and breadth to displacement, providing certain track elasticity, and the power that rail is suffered passes to sub rail foundation.The design parameters of determining the rails fastener must be considered the situation of its correlation engineering: line arrangement mode, circuit technical data, road speed, vehicle axle weight and rail type etc.The main design parameters of fastener comprises: buckle press, anti-creep resistance, node rigidity, fatigue performance, gauge and horizontal adjustment amount, insulating properties etc.
The D type just joist steel rail fastener of constructing before the transformation of the way by 20 millimeters designs of rail taper liner thickness of slab, is applicable to 43Kg/m rail, 50Kg/m rail.Main parts size has: buckle positioning support, buckle fine setting iron seat, 70 type standard buckles.Buckle positioning support in the rail fastening directly is connected with crossbeam, and the lateral adjustments amount is 50 millimeters, and the iron seat finely tuned by buckle and the buckle positioning support relies on the M24 bolt and stepped tooth is fastening up and down, and its lateral adjustments amount is 3 millimeters.Utilize the shoulder block up and down of 70 type standard buckles to differ from 2 millimeters, in fact may produce maximum interspace is 1 millimeter.But in using at the scene, connection between rail fastening and crossbeam is insecure, the insulation of rail fastening circuit is reliable inadequately, mistaking signal once, influence driving, and the lateral adjustments amount of buckle fine setting iron seat is 3 millimeters only, and regulated quantity is little, can not solve construction error and track side abrasion and cause the problem that gauge transfinites, therefore certain limitation is in use arranged.
Summary of the invention
The utility model purpose is a kind of just joist steel rail fastener of the construction that plays the role of positioning that the railroad track both sides guarantee the rail tram that is fixed in of design, connect insecure to solve rail fastening and crossbeam, the circuit insulation is unreliable, the little technical barrier of buckle fine setting iron seat lateral adjustments amount.
Specifically, a kind of just joist steel rail fastener of the construction that plays the role of positioning that the railroad track both sides guarantee the rail tram that is fixed in is made of buckle positioning support, crossbeam side gusset, adjustable buckle, stop washer, positioning bolt; The buckle positioning support directly is connected with crossbeam side gusset, and adjustable buckle is connected on the crossbeam side gusset by positioning bolt, stop washer and the one end leans at rail bottom rail and props up, and an other end is pressed on the crossbeam side gusset.
The utility model rail fastening has following major advantage:
1, fastener and crossbeam connect close and firm.Novel rail fastening adopts parts such as inside and outside adjustable buckle, stop washer, fastener and crossbeam is had closely connect.
2, enough intensity and durability are arranged.The railroad track traffic operation time is long, rate of traffic flow is high, the maintenance condition is poor, and the rail fastening after the transformation of the way has enough intensity and durability, to guarantee traffic safety.
3, certain gauge and horizontal adjustment performance are arranged.Novel rail fastening has certain gauge, horizontal adjustment performance, transfinites to solve the rail wear and the differential settlement of structure and gauge, the rail level that construction error was caused.
4, the good insulation performance performance is arranged.Novel rail fastening bearing plate bars adopts the special taper liner plate of neoprene, and certain directionality is arranged, and webbing is placed on the rail outside during installation, adopts nylon insulation angle, and insulating properties are than good before changing a social system.
5, certain general interchangeability being arranged. fastener structures should be made every effort to simply, and component are few, has certain general interchangeability, and cost is low, construction and easy to maintenance.
Description of drawings
Figure is the utility model just joist steel rail fastener structures schematic diagram of constructing.
The specific embodiment
As shown in the figure, constructing just, joist steel rail fastener is made of buckle positioning support 1, crossbeam side gusset 2, adjustable buckle 3, stop washer 4, positioning bolt 5; Buckle positioning support 1 directly is connected with crossbeam side gusset 2, and adjustable buckle 3 is connected on the crossbeam side gusset 2 by positioning bolt 5, stop washer 4 and the one end leans at rail 7 bottom rails and props up, and an other end is pressed on the crossbeam side gusset 2.Between adjustable buckle 3 and rail 7 bottoms, be placed with insulation angle 8.Insulation angle 8 one sides are for to prop up the bending shape that matches with rail 7 rails, an other lateral buckling and adjustable buckle 3 must cave in bend corresponding.Be placed with rubber pad 6 in rail 7 bottoms.
Novel rail fastening is applicable to 43Kg/m rail, 50Kg/m, 60Kg/m rail by 20 millimeters designs of rail rubber mat plate thickness of slab.Main parts size has: buckle positioning support, outer adjustable buckle, interior adjustable buckle, stop washer, nonprene washer, nylon insulation angle.Buckle positioning support in the rail fastening directly is connected with crossbeam side gusset, and the lateral adjustments amount is 50 millimeters, and adjustable buckle is finely tuned along the rail direction, and laterally the maximal regulated amount is 32 millimeters.
