Abstract
The utility model discloses a device used for solving the railway ballast play problem at long-span bridge girder ends of ballast tracks. The device comprises railway ballasts arranged on a bridge girder body, railway tracks are arranged on the railway ballasts, and ballast baffles are arranged on one side face of the railway ballasts on the bridge girder body along the direction of the railway tracks. The ballast baffles and the bridge girder body are in an integrated structure. Anti-falling structures are arranged between adjacent ballast baffles. The anti-falling structures are connected with the ballast baffles through pothooks. The ballast baffles solve the problem that the railway ballasts arch up or fall off at girder gaps. The shortcomings that steel rails are not smooth in vertical direction, the geometric shapes and positions of steel rail telescopic adjusting devices are hard to maintain and the like due to railway ballast play can be effectively prevented from occurring. Maintenance and repair work load is significantly reduced. The device used for solving the railway ballast play problem at the long-span bridge girder ends of the ballast tracks has the advantages of being simple in structure, easy to machine, wide in sources, low in cost, and reliable in quality.
Description
Technical field
The utility model relates to the railroad track technical field, refers to particularly it is a kind of device that solves Ballast track long span bridge beam-ends railway ballast play.
Background technology
Railway ballast is the bulk solid structure, when being equipped with tiny fragments of stone, coal, etc. track on the long-span bridge, falls tiny fragments of stone, coal, etc. phenomenon, the current measure of generally taking to arrange at beam seam place cover plate for preventing the flexible beam-ends that causes of bridge.After cover plate was set, no matter whether long-span bridge beam-ends steel rail laying expansion and cotraction regulator, and play all appears in railway ballast easily, causes the rail irregularity.When the long-span bridge beam-ends does not arrange rail overlapping device, the elongation of summer high temperature beam body can cause the railway ballast arch of beam seam place, winter low temperature beam body shortens the whereabouts that causes beam seam place railway ballast, railway ballast arch whereabouts can cause the vertical irregularity of rail, and it is just relevant therewith to have opened on the rail that circuit occurs summer doming effect at present.When long-span bridge beam-ends steel rail laying expansion and cotraction regulator, because rail overlapping device is the weak link of gapless track, in bridge beam body under the flexible and locomotive load effect repeatedly, larger relative displacement can occur between expansion and cotraction regulator place beam rail, the easy play of railway ballast at beam seam place, cause the railway ballast at rail overlapping device place inhomogeneous, the vertical irregularity of rail will occur, the adjuster track geometry is difficult to the diseases such as maintenance.Therefore, Ballast track Longspan Bridge seam place arranged the very reasonable part of method existence of rail overlapping device in the past, the play of railway ballast can cause the vertical irregularity of beam-ends rail, rail overlapping device track geometry to be difficult to the diseases such as maintenance, when serious even can be critical to train operating safety, maintenance to works department has also caused very large trouble, therefore, need prior art is improved.
The utility model content
The purpose of this utility model is exactly the deficiency that will solve the above-mentioned background technology, a kind of device that solves Ballast track long span bridge beam-ends railway ballast play is provided, can effectively prevents from causing because of the railway ballast play generation of the harm such as rail arch, rail overlapping device track geometry are difficult to keep.
The technical solution of the utility model is: a kind of device that solves Ballast track long span bridge beam-ends railway ballast play, it comprises the railway ballast that is arranged on the bridge beam body, be provided with railroad track at railway ballast, it is characterized in that: the direction side of railway ballast on bridge beam body along railroad track is provided with gear tiny fragments of stone, coal, etc. plate, and described gear tiny fragments of stone, coal, etc. plate and bridge beam body are the integral type structure.
In such scheme:
Described bridge beam body is steel work, and gear tiny fragments of stone, coal, etc. plate is structure of steel product, mode and bridge beam body the be combined as a whole formula structure of gear tiny fragments of stone, coal, etc. plate by welding.
Described bridge beam body is concrete structure, and gear tiny fragments of stone, coal, etc. plate is reinforced concrete structure, and gear tiny fragments of stone, coal, etc. plate is by anchoring adhesive and the bridge beam body formula structure that is combined as a whole.
Be provided with Anti-falling structure between the adjacent gear tiny fragments of stone, coal, etc. plate, Anti-falling structure is connected by hook with gear tiny fragments of stone, coal, etc. plate.
Described Anti-falling structure is the plastic net structure.
The utility model has the advantage of:
1, keeps off the problem that arranging of tiny fragments of stone, coal, etc. plate solved in the past beam seam place railway ballast arch or fallen, can effectively prevent from being difficult to the generation of diseases such as keeping owing to the railway ballast play causes the vertical irregularity of rail, rail overlapping device track geometry, significantly reduce the maintenance workload.
2, be equipped with Anti-falling structure in this device, can have prevented that railway ballast or other foreign material from falling and contaminated environment or injure pedestrian etc. from the beam seam, also can avoid the maintenance personnel that falling accident occurs.
3, the utility model is simple in structure, and used former material is common iron or concrete material, and processing is simple, wide material sources, cheap, reliable in quality.
