Description
Technical field
The utility model relates to the most advanced and sophisticated frame rail reinforcement tools of a kind of rail yard point tongue for rail yard point tongue tip place.
Background technology
Track switch is the necessaries that locomotive changes between two railway lines, and primarily of steering unit, railway frog and guard rail part and coupling part composition are one of links the weakest during railway line is formed.Rolling stock turnover track switch, by tongue pilot engine, adjusts to location or antiposition according to the instruction of driving; The transition operation of tongue is made a connection to have come by pull bar by electricity entirely.
Railway is very strict to the quality requirement of turnout switch part, and railway " skill rule " regulation turnout rail is apart from static allowable error value+3.-2mm, and the point of switch gauge allowable variation installing electricity favourable turn must not more than 1mm., wearing and tearing large to the impact of tongue at the situation Train of circuit instability greatly also very easily damage, and directly affect transport.
The impact that between the switch tie under the changing points part point of switch, (sleeper box) makes a connection because track switch is electric cannot penetrate horizontal beam of lifting and reinforce, cause stock rail and the point of switch nearly 1.2m length unsettled, the switch tie at point of switch place has lost the ability of the effect of bearing rail power transmission and opposing circuit displacement in length and breadth.Traditional work mode takes bundle rail method to reinforce, but the part that bends up that the longitudinal rail of bundle rail may collide electricity favourable turn pull bar causes device damage and potential safety hazard.How convenient and swift, handling these problems safely and effectively well is problems that those skilled in the art are concerned about.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide the most advanced and sophisticated frame rail reinforcement tools of a kind of rail yard point tongue, and the switch tie that effectively can solve point of switch place cannot bear the problem of the effect of rail power transmission and the opposing circuit ability of displacement in length and breadth.
The technical scheme that the utility model solves is, comprise switch tie, before and after switch tie the corner of two side lower parts respectively spiral-lock have equal leg angle, the two ends of switch tie are stretched out at the two ends of equal leg angle, two groups of connecting angles linked together by the equal leg angle of both sides, front and back the two ends of stretching out are equipped with all successively, the connecting angle of inner side and the both ends of the surface of switch tie are close to, the boatswain chair of level is equipped with in the outside of switch tie both sides slide plate on switch tie, boatswain chair is equipped with the U-bolt for equal leg angle and switch tie being closely fixed together.
The utility model novel structure is unique, and advantages of simple, easily produces, and use material simple and easy to get, peace is torn open quick, and labor intensive is little, and the steel wood mixing switch tie whole structure of formation is good, and cost is low, safe and reliable, easy to use, effective.

Fig. 1 is front view of the present utility model (only showing the switch tie of half).
Fig. 2 is top view of the present utility model (only showing the switch tie of half).
Fig. 3 is cross sectional side view of the present utility model.
Fig. 4 is using state figure of the present utility model (only display is provided with one end of electricity favourable turn).
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Provided by Fig. 1-4, the utility model comprises switch tie, before and after switch tie 6 corner of two side lower parts respectively spiral-lock have equal leg angle 5, the two ends of switch tie 6 are stretched out at the two ends of equal leg angle 5, two groups of connecting angle 1a, 1b linked together by the equal leg angle of both sides, front and back the two ends of stretching out are equipped with all successively, the connecting angle 1b of inner side and the both ends of the surface of switch tie 6 are close to, the boatswain chair 3 of level is equipped with in the outside of switch tie 6 both sides slide plate 2 on switch tie, boatswain chair 3 is equipped with the U-bolt 4 for equal leg angle 5 and switch tie being closely fixed together.
For ensureing result of use, described equal leg angle 5 has identical two groups, and its specification is 100 × 100 × 12mm, long 4.5m, the corner of two groups of difference spiral-locks, two side lower parts before and after switch tie 6;
The equal leg angle of described connecting angle 1a, 1b to be specification be 100 × 100 × 12mm, length is 230mm, and the outside of a connecting angle 1b vertical plane and the end face of switch tie 6 of inner side are close to;
The steel plate of described boatswain chair 3 to be specifications be 100 × 350 × 16mm;
The diameter of described U-bolt 4 is 20mm.
When the utility model uses (as shown in Figure 4), according to the frame rail scheme formulated, first the equal leg angle 5 that 4.5m long size is 100 × 100 × 12mm is intercepted, remove ballast aggregate around switch tie, equal leg angle 5 is passed below the fixing steel framework 9 being used for installing electricity favourable turn 7, equal leg angle is held in the corner of two side lower parts before and after switch tie, shelves or hang and indulge on girder steel 8 in frame rail; Withstand switch tie two ends with the long connecting angle 1b of 230mm and weld together with equal leg angle 5; The boatswain chair 3 coordinating 16mm thick at the U-bolt 4 of the outside φ 20 of the slide plate 2 of switch tie is fastening, adopts pad nut to fix; The equal leg angle two ends of finally shelving or hanging on longeron are welded and fixed with connecting angle 1a again, form an overall steel wood mixing switch tie, thus utilize the gap of the lower 105mm of electricity favourable turn, equal leg angle crosses electricity favourable turn, is placed in or hangs on railway line frame rail steel longeron 8, fix frame rail with U-bolt, after the end of job, cut off connecting angle, equal leg angle is extracted out, for having enough to meet the need use; Compared with prior art, the utility model uses material simple and easy to get, and peace is torn open quick, and labor intensive is little, change the reinforcing mode that tradition adopts rail bundle rail, the switch tie at effective solution point of switch place cannot bear the problem of the effect of rail power transmission and the opposing circuit ability of displacement in length and breadth, and the steel wood mixing switch tie whole structure of formation is good, and cost is low, safety is guaranteed, easy to use, effective, there is good Social and economic benef@.
