Abstract
A kind of railway track compound gap bridge joint, comprise the inner side bridge for embedding I-shaped rail grooves on two sides and outside bridge, described outside bridge is made up of bridge body and transition guide, described transition guide upper longitudinal to curved shape, arc heights of roofs 2-5mm.Described inner side bridge, between outside bridge and rail, be provided with beam.A kind of railway track compound gap bridge joint of the present utility model, by bridge outside rail joint place is designed to rail joint transition guide, when making train wheel grind rail joint place, the strength of wheel all acts in transition guide, avoid the impact of wheel to rail joint position, make the rail joint damaged have cheap alternative, be more the reduction of the loss changed rail and bring.In addition, beam is set between rail and bridge, reduces train through the impact of out-of-date vibrations on bridge, also ensure that stability and the safety of transition guide simultaneously.
Description
Technical field
The utility model relates to a kind of railway track gap bridge piecing devices, is specially one and can slows down the wearing and tearing of rail joint position, improve the gap bridge joint in rail application life.
Background technology
At present, be in operating railway line, due to the enormous impact power that the wheel of high-speed cruising produces rail joint place, rail joint place and switch zones is made to become rail position the most easy to wear, the degree of wear at this two place directly affects railway operation safety, therefore must change rail when wearing and tearing acquire a certain degree, line outage can be brought thus to lose and change rail cost and artificial input etc.To wear and tear the problems referred to above brought to reduce rail joint place, have employed rail joint bridge and being welded with the mode of high-abrasive material, but weld seam is easily ftractureed due to the high-strength impact power of wheel, cause gap bridge joint fails.In addition also have and adopt the integral structure component of carbon steel as gap bridge joint, and due to the anti-wear performance of carbon steel on the low side, application life is short, once bridge portion wears away limit, slows down the function that joint impacts and just greatly reduces.It is combine and easily loosen by force between bridge and rail that the mode installing gap bridge joint additional has another problem, can cause safety problem thus.
Summary of the invention
For the problems referred to above, devise a kind of railway track compound gap bridge joint, solve gap bridge joints wear and loosening deficiency.
A kind of railway track compound gap bridge joint, comprise the inner side bridge for embedding I-shaped rail grooves on two sides and outside bridge, it is characterized in that described outside bridge is made up of bridge body and transition guide, described transition guide upper longitudinal to curved shape, arc heights of roofs 2-5mm.
Described a kind of railway track compound gap bridge joint, is characterized in that described inner side bridge, is provided with beam between outside bridge and rail.
A kind of railway track compound gap bridge joint of the present utility model, by bridge outside rail joint place is designed to rail joint transition guide, when making train wheel grind rail joint place, the strength of wheel all acts in transition guide, avoid the impact of wheel to rail joint position, make the rail joint damaged have cheap alternative, be more the reduction of the loss changed rail and bring.In addition, beam is set between rail and bridge, reduces train through the impact of out-of-date vibrations on bridge, also ensure that stability and the safety of transition guide simultaneously.
Accompanying drawing explanation
Fig. 1 is inner side bridge schematic diagram;
Fig. 2 is outside bridge and transition guide schematic diagram;
Fig. 3 is the A direction view of Fig. 2;
Fig. 4 is transition guide scheme of installation.
In figure, 1-wheel; 2-transition guide; Bridge outside 3-; 4-beam; 5-bolt; Bridge inside 6-; 7-rail.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
It is bridge schematic diagram inside current a large amount of rail joint used shown in Fig. 1.Its shaped exterior shape is mated with the inner groovy of the I-shaped rail of current standardization.The inner side of rail joint is directly entrenched in during use.
Bridge and transition guide structural representation outside rail joint of the present utility model shown in Fig. 2.Its underpart shape and structure is identical with inner side bridge, be all by standard-required with the bridge of I-shaped rail matching grooves, its top is transition guide or can be described as transition rail, and its width is slightly less than standard rail width.
Shown in Fig. 3, outside rail joint and transition guide top are arcuate structure, and arc heights of roofs is two ends height 2-5mm comparatively.
Bridge shown in Fig. 4 is arranged on two rail joint place schematic diagrames, the inside and outside both sides of I-shaped rail 7 are separately installed with inner side bridge 6 and outside bridge 3, both sides clamping plate connect firm by bolt 5, bridge is caused to loosen in order to reduce vibrations, beam 4 is also provided with between bridge and rail, the top of outside bridge is transition guide 2, transition guide top is arcuate shape, its longitudinal two ends flush with rail or a little less than rail, centre is then higher than rail 2-5 millimeter, train causes in transition guide by the rail transition of joint one end outside its wheel 1 of rail joint, then be transitioned into another rail again from the transition guide other end, steadily cross rail joint, avoid the impact to rail joint, decrease rail to be hit the damage caused.
Above-mentioned outside bridge adopts the alloy steel material forging and stamping of our factory's research and development to form, the all more common rail of its intensity and stiffness wants high, detect through Metals & Chemistry Research Institute, tensile strength improves 20%, and stiffness improves 40%(60) type.Product is through Quality Supervision and Inspection Center of former Ministry of Railways railway construction inspection point check character standardization and allowance enters road test, through several years tentative use, respond well.
