Abstract
The utility model discloses a long rail propelling movement auxiliary device, including cable suspension device and running gear, cable suspension device includes crossbeam and the two piece longerons of fixed mounting at the crossbeam both ends, running gear is including transversely installing at two main shafts of two longerons bottoms and installing the walking wheel at two spindle noses respectively, two main shafts with the crossbeam is parallel, two longerons are all perpendicular with the crossbeam, use fortune roof beam car or other railways rail vehicle as draw gear, in the transportation, it is inboard to treat that the rail of laying is arranged in to the long rail of propelling movement, uses wire rope or iron chain will treat the long rail of propelling movement and hangs in proper order the utility model discloses on the auxiliary device's of required protection the crossbeam, using draw gear to pull long rail and moving ahead simultaneously with long rail propelling movement auxiliary device, the structure is simpler, facilitates the use, can only use even the utility model discloses with the long rail propelling movement of the supporting completion of draw gear, the propelling movement cycle is short, can effectively shorten construction cycle.
Description
Technical field
The utility model relates to gapless line technical field of transportation, particularly relates to a kind of gapless line and pushes servicing unit.
Background technology
Along with greatly developing of domestic high-speed railway, road speed also increases substantially, in order to ensure High Speed Railway Trains riding stability, existing high-speed railway all adopts gapless track, so-called " gapless track ", exactly the rail of not holing, quenchless 25m is long, in the way of base factory gas pressure welding or Contact welding, be welded into the gapless line of 200m to 500m, then transport to place of laying a railway track, be welded into the length of 1000m to 2000m again, be taped against on circuit and just become one section of gapless track.If do not have the difficulty in processing, transport, construction, theoretically, " gapless track " can endless.
The high-speed railway of current China adopts the gapless line of 500m substantially, specifically laying a railway track in process, T11 is mostly adopted to transport rail car, but T11 transports rail car limited amount, constrain the process of laying a railway track to a certain extent, therefore, a kind of simple and practical gapless line conveying arrangement of development and Design is this area urgent problem.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of gapless line and pushes servicing unit, transporting rail car to have bad luck the cycle long, restricting the problem of process of laying a railway track for solving in existing process of laying a railway track T11.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of gapless line pushes servicing unit, comprise erecting by overhang and walking mechanism, described erecting by overhang comprises crossbeam and is fixedly mounted on two longerons at crossbeam two ends, described walking mechanism comprises the road wheel being laterally arranged on two main shafts bottom two longerons and being arranged on two spindle noses respectively, described two main shafts are parallel with described crossbeam, and described two longerons all and beam vertical.
Described crossbeam and longeron are square steel, and crossbeam two ends are welded with in the middle part of two longerons.
Described road wheel is the rail wheel coordinated with rail end face, and its outer edge surface is secondary step structure, and when walking, one section that diameter is less is positioned at rail surface, and one section that diameter is larger is positioned at inside rail, and described road wheel is connected with bearing between main shaft.
Coated for crashproof rubber sleeve outside described main shaft.
The beneficial effect adopting technique scheme to produce is: by using 32 groups of the utility model as gapless line braced structures, use Beam transportation vehicle or other railroad track vehicles as draw-gear, in transportation, to wait that pushing gapless line is placed in inside the rail that lays, wire rope or iron chains is used to wait that pushing gapless line hangs successively on the crossbeam of the utility model servicing unit required for protection, use draw-gear traction gapless line and gapless line to push servicing unit to move ahead simultaneously, transport for rail car relative to existing T11, structure is simpler, easy to use, even can the utility model and the supporting gapless line that completes of draw-gear be only used to push, the propelling movement cycle is short, effectively can shorten construction period, improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In the accompanying drawings: 1, crossbeam; 2, longeron; 3, road wheel; 4, main shaft.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
T11 car must be used to solve the propelling movement of existing gapless line, cycle of having bad luck is long, problem long in time limit, the utility model provides a kind of gapless line to push servicing unit, comprise erecting by overhang and walking mechanism, described erecting by overhang comprises crossbeam 1 and is fixedly mounted on two longerons 2 at crossbeam 1 two ends, described walking mechanism comprises the road wheel 3 being laterally arranged on two main shafts 4 bottom two longerons 2 and being arranged on two main shaft 4 ends respectively, described two main shafts 4 are parallel with described crossbeam 1, and described two longerons 2 are all vertical with crossbeam 1; Described crossbeam 1 and longeron 2 are square steel, and crossbeam 1 two ends are welded with in the middle part of two longerons 2; Described road wheel 3 is the rail wheel coordinated with rail end face, and its outer edge surface is secondary step structure, and when walking, one section that diameter is less is positioned at rail surface, and one section that diameter is larger is positioned at inside rail, and described road wheel 3 is connected with bearing between main shaft 4; Coated for crashproof rubber sleeve outside described main shaft 4.
In concrete use procedure, the utility model and the draw-gear that can walk on the railroad track support the use, gapless line head end and draw-gear specify, the utility model is evenly arranged at draw-gear rear, spacing between adjacent two covering devices is to ensure that gapless line does not stress bending being limited, general for 500m gapless line, 32 groups of servicing units disclosed in the utility model are set at draw-gear rear, use Beam transportation vehicle or other railroad track vehicles as draw-gear, in transportation, to wait that pushing gapless line is placed in inside the rail that lays, wire rope or iron chains is used to wait that pushing gapless line hangs successively on the crossbeam of the utility model servicing unit required for protection, use draw-gear traction gapless line and gapless line to push servicing unit to move ahead simultaneously, transport for rail car relative to existing T11, structure is simpler, easy to use, even can the utility model and the supporting gapless line that completes of draw-gear be only used to push, the propelling movement cycle is short, effectively can shorten construction period, improve operating efficiency.
