Abstract
The utility model relates to a dual elastic adjustable fastener which is a rail fastener with elastic strips. The dual elastic adjustable fastener comprises a track gauge apron, a track gauge adjusting block and elastic strips. The dual elastic adjustable fastener can be fixed to the screw spike of a sleeper by nuts for buckling rails. The dual elastic adjustable fastener is characterized in that the added track gauge apron and the track gauge adjusting block have a vertical contact face which can not parallel the rail web of the rail; the track gauge can be adjusted by moving the track gauge adjusting block. The other embodiment is that the track gauge can be adjusted by turn the nuts on the screw bolt which is sheathed on the rolled tail part of the sigma shaped plate elastic sheet fastener. The utility model can conveniently adjust the track gauge and the track height of the track of the elastic fastener without replacing parts, and can cause the track gauge and the track height to keep in qualified state in the labour saving and time saving way.
Description
The utility model is a kind of rail fastening that uses spring or plate shell fragment, is used for rail is fixed on sleeper, and can adjusts gauge, rail height easily.
In the prior art, TB1911.1-87 spring I type tightening means for height-adjusting mainly is made up of gauge apron, spring and apron block, with nut its bolt is withheld rail on the screw spike of concrete sleeper, this fastener is to realize by gauge apron and the apron block of changing different in width when adjusting gauge, spare part is many, and it is little to adjust inconvenience and adjusting range.
The purpose of this utility model is to design a kind ofly need not change parts and can adjust the elastic bar fastener of gauge on a large scale.
The purpose of one of the utility model is achieved in that it is mainly by gauge apron, gauge adjusting block, spring are formed, gauge adjusting block and gauge apron have and the uneven vertical contact surface of the rail web of the rail, can do two gauge adjusting blocks opposing when adjusting gauge or relatively move, because inclined-plane contact and gauge apron can not be made move left and right, thereby make rail make move left and right, when reaching assigned address, spring is enclosed within on the screw spike of concrete sleeper and uses nut screwing clamping, thereby realized the adjustment gauge.
The concrete structure of utility model is provided by following examples and accompanying drawing: the assembly drawing of embodiment 1 as shown in Figure 1.The assembly drawing of embodiment 2 as shown in Figure 2.1-gauge apron among the figure; 2,3-gauge adjusting block; 4,25-spring; The 5-nut; The 6-screw spike; The 7-insulation spacer; The 8-rail; The 9-concrete sleeper.
Spring among the embodiment 1 (4) is a W shape, and spring among the embodiment 2 (25) is a V-arrangement.
Fig. 5 is the structure chart of gauge apron; Fig. 6 is the structure chart of gauge adjusting block.This device is mainly by gauge apron (1), and gauge adjusting block (2), (3) are formed, join with spring, nut etc.The technical characterictic of gauge apron has been inclined-plane (16), and the technical characterictic of gauge adjusting block has been inclined-plane (15), and the inclined-plane is and the uneven vertical plane of the web of the rail, on inclined-plane (15), (16) tooth is arranged.
During installation, with gauge apron, gauge adjusting block is placed in the concrete sleeper rail support groove, press spring, cover top nut, it is opposing that two gauge adjusting blocks are done, and relatively moves, because inclined-plane contact and gauge apron can not be made move left and right, thereby make rail make move left and right, can make rail be in the gauge position of requirement, thereby adjust gauge.Owing to have tooth on gauge apron and the gauge adjusting block contact surface, thereby gauge adjusting block can not skid off because of vibration.
Because the contact surface of gauge apron and gauge adjusting block is vertical, therefore when increasing the pad height adjusting cushion plate under the rail, rail and gauge adjusting block can rise together along the vertical barricade (16) of gauge apron, do not realize adjusting the rail height thereby the gauge variation does not take place again.
The two adjustable technical schemes of another kind of solution spring secures rail to sleeper are that this device mainly is made up of the bolt (22) of fastener (21) or (25) and two adjustable gauges, the fastener of this device is the plate shell fragment (or V-arrangement spring) of a kind of σ of curving, adjusts gauge and is by rotation and realize with the nut on the bolt that fastener (or iron seat) links to each other.The assembly drawing of the embodiment 3 of this utility model as shown in Figure 3, the assembly drawing of embodiment 4 as shown in Figure 4:
21-σ shape plate shell fragment; The 22-gauge is adjusted bolt; The 23-cushion block; 24-iron seat; 25-V shape spring; 30-gauge adjusting nut; The 5-nut; The 6-screw spike; The 7-insulating pad; The 8-rail; The 9-concrete sleeper.
Fig. 7 is the structural plan figure of V-arrangement spring, Fig. 8 is the unfolding assumption diagram of σ shape plate shell fragment, Fig. 9 is the structure chart of iron seat 24, Figure 10 is the structure chart that gauge is adjusted bolt 22, Figure 11 is the structure chart of U bolt 26, Figure 12 is the structure chart of cushion block 23, and the major technique feature of σ shape plate shell fragment is to curve σ shape with steel plate, and its afterbody of rolling has two holes; The major technique feature of bolt (22) is to have a nut (30) on it at least, and one (29) contacting with rail or cushion block are thicker.The bolt that screws on nut passes two holes of shell fragment afterbody, and an end withstands rail (or cushion block), and an end withstands shell fragment, and swivel nut is having than length of adjustable bolt then, thereby make the rail move left and right adjust gauge.In addition,, certain altitude is arranged because that bolt withstands (29) of rail is thicker, so as to adjust the rail height, when rail rises, bolt head still can block rail foot, keeps gauge constant.
For the stability that increases by two bolts prevents to be offset about it, bolt can be made U-shaped as shown in figure 11.
When using the V-arrangement spring, needing increases iron seat (24) as shown in Figure 9, and the major technique feature of iron seat is that two wall (27), (28) that have the hole are arranged.Bolt can pass this hole, rotary sleeve on bolt nut (30) thus the effective length that can change bolt realize to be adjusted gauge.
The new shape of this practicality can make railway department save the standby fastener that large quantities of adjustment gauges are used when maintenance track, and gauge is adjusted on saving of work and time ground, the rail height makes track be in eligible state, and tangible technical economic benefit is arranged.
