Abstract
The utility model relates to a spring bar height-regulating fastener, belonging to the technical field of a railway sleeper fastener. The utility model is composed of a screw thread spike, a screw, a big plane pad, a spring bar, a track gauge stopping plate, a track gauge stopping block, a concrete sleeper, etc. The concrete sleeper is provided with a baffle seat and the track gage baffle, and the track gauge baffle is provided with an upright wall with a slope. A stud of the track gauge is arranged between a track and the track gauge baffle; a pressure-bearing surface of the track gauge baffle is arranged on the track; a dovetail is arranged between the two upright walls of the track gauge baffle, and is fixed by the screw thread spike. The utility model has the advantages of good performance, high regulating range, and safety.
Description
The utility model belongs to railway concrete sleeper fastening technical field, is a kind of Spring bar height-regulating fastener.
The still nonelastic tightening means for height-adjusting of present domestic 50Kg/m rail concrete sleeper circuit, fastener is divided into two kinds of 50Kg/m rail intermediate fastening and 50Kg/m rail joint fasteners again, so the existing joint of rail joint and the middle location rail to 50Kg/m rail concrete sleeper circuit sinks, the circuit irregularity that railway roadbed is loose and freeze injury causes not can not get timely radical cure because there being suitable elasticity tightening means for height-adjusting.Now with spring I type fastener to circuit with make firm by ramming, during the way regulation circuit disease of pad regulation, it is less that it adjusts aspect ratio, the gauge plate washer work elevation angle can reach 15 degree, the function of the gauge plate washer of this structure particularly keeps the ability of gauge at this moment, the ability of opposing horizontal component reduces greatly, even gauge plate washer " go up a heatable brick bed " can take place, serious problems such as gauge is out of control have influenced 50Kg/m rail concrete sleeper line quality.
The purpose of this utility model provides a kind of reasonable in design, the elasticity tightening means for height-adjusting that functional performance is good.
The utility model is by screw spike, nut, big flat washer, spring, the gauge plate washer, mid-rail is apart from link stopper, joint gauge link stopper, the plate washer seat, rubber mat plate, splice bar, rail, concrete sleeper is formed, the plate washer seat is arranged on concrete sleeper, the gauge plate washer, there is the wall that has reinforcing rib gauge plate washer both sides, under the inclined-plane wall groove is arranged, there is square hole the centre, the gauge link stopper has stud, pressure-bearing surface, dovetail, groove, the stud of gauge link stopper places between rail and the gauge plate washer, pressure-bearing surface places on the rail, dovetail places between two walls of gauge plate washer, spring one end is pressed on the groove of gauge plate washer, the other end is pressed on the groove of gauge link stopper, the spring big flat washer, nut, screw spike is fixed.
The utility model has the advantages that reasonable in design, functional performance are good, guarantee that circuit is smooth-going, buckle press is all rare, and it is big to heighten scope, safe and reliable.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a gauge barrier structure schematic diagram of the present utility model.
Fig. 3 is the vertical view of the utility model Fig. 2.
Fig. 4 is the structural representation of gauge link stopper of the present utility model.
Fig. 5 is the vertical view of Fig. 4 of the present utility model.
Number in the figure is described as follows, and 1, screw spike, 2, nut, 3, big flat washer, 4, spring, 5, the gauge plate washer, 6, joint gauge link stopper, 7, mid-rail is apart from link stopper, 8, plate washer seat, 9, rubber mat plate, 10, splice bar, 11, rail, 12, concrete sleeper, 13, groove, 14, base, 15, reinforcing rib, 16, wall, 17, groove, 18, pressure-bearing surface, 19, stud, 20, dovetail, 21, square hole.
As shown in the figure the utility model by screw spike 1, nut 2, big flat washer 3, spring 4, gauge plate washer 5, mid-rail apart from link stopper 6, joint gauge link stopper 7, plate washer seat 8, rubber mat plate 9, splice bar 10.Rail 11, concrete sleeper 12 is formed, plate washer seat 8 is arranged on concrete sleeper 12, gauge plate washer 5, there is the wall 16 that has reinforcing rib gauge plate washer 5 both sides, groove 13 is arranged under the inclined-plane wall, there is square hole 21 centre, gauge link stopper 6 has stud 19, pressure-bearing surface 18, dovetail 20, groove 17, the stud 19 of gauge link stopper 6 place between rail 11 and the gauge plate washer 5, pressure-bearing surface 18 places on the rail 11, dovetail 20 places between two walls 16 of gauge plate washer 5, and spring 4 one ends are pressed on the groove 17 of gauge link stopper 6, and the other end is pressed on the groove 13 of gauge plate washer 5, spring 4 usefulness big flat washer 3, nut 2, screw spike 1 is fixing, and gauge link stopper 6 is different apart from the position that link stopper 7 uses with mid-rail, the gauge link stopper is used in the rail connection, mid-rail is used in position between two one steel rails, 11 joints apart from link stopper 7, and rubber pad 9 is arranged below rail, between rail 11 and gauge link stopper 6 splice bar is arranged.The pressure-bearing surface 18 of gauge link stopper 6 one ends is pressed on the rail 11, and other end dovetail 20 shapes place between two walls of rail 11 plate washers 5, slippage up and down, and dovetail 20 shapes play the guiding role, and prevent that gauge link stopper 6 or 7 from misplacing.Gauge plate washer 5, gauge link stopper 6 or 7 are equipped with semi-circular grooves 13, and spring 4 one ends are pressed on the groove 13 of gauge plate washer 5, and the other end is pressed on the groove of gauge link stopper 6 or 7, make the condition of work of spring 4 stable.The profile of gauge plate washer has guaranteed rationally laying of spring, makes spring its position in heightening be in stable state all the time.The stud fixed size of gauge link stopper is clipped between rail and the gauge plate washer and transmits horizontal component, and its pressure-bearing surface and rail are closely connected.Spring is not directly withheld rail but is withheld rail by the gauge link stopper, and it is that spring forward and backward withheld an active force equilibrium that spring is withheld the position.In heightening, the gauge link stopper is along moving vertically between gauge plate washer two walls, so that the pressure-bearing surface of gauge link stopper remains with rail is closely connected, do not have gauge link stopper elevation angle phenomenon.
It is as follows to install the Spring bar height-regulating fastener program, places the plate washer seat earlier, lays the gauge plate washer again, and plate washer seat and gauge plate washer should require to determine the respective number specification according to the circuit gauge.Answer caution area tap place joint gauge link stopper when laying the gauge link stopper, middle place uses mid-rail apart from link stopper, the gauge link stopper should be squeezed between rail and the gauge plate washer in the crack gently, install spring, plain cushion has high input, nut, tighten nut, both sides correspondence simultaneously tighten, and notice that at any time the gauge link stopper is gone into the position and spring end two limbs are gone into a gauge link stopper groove situation.
In sum, the utility model is the comparatively desirable a kind of Spring bar height-regulating fastener of 50Kg/m rail concrete sleeper circuit.
