The specific embodiment
Core of the present utility model is to provide a kind of device for fixing running tracks, and this device for fixing running tracks can be convenient to the fixed installation of rail, saves man-hour, improves installation effectiveness.
In order to make those skilled in the art understand better the technical solution of the utility model, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1, the structural representation of the device for fixing running tracks that Fig. 1 provides for the utility model.
As shown in Figure 1, the device for fixing running tracks that the utility model provides comprise for the base plate 2 of steel rail laying 1 and be arranged on being used for the fixedly rail pressing device of rail 1 bottom on this base plate 2, and base plate 2 and rail pressing device is the integral type molding structure.
As can be known, in the above-mentioned device for fixing running tracks, base plate 2 and rail pressing device are the integral type molding structure, the relative position that is base plate 2 and rail pressing device is fixing, on-the-spot directly steel rail laying 1 gets final product, and does not adjust about need to not carrying out at the rail pressing device to rail 1 both sides, for uneven highway section, therefore the phenomenon that rail pressing device also can not occur sliding does not need again to adjust yet.Be convenient on the one hand the installation of rail 1, saved on the other hand the time of adjusting, saved man-hour.
Above-mentioned rail pressing device comprises upper cover plate 31 and base 32, particularly, that base 32 is the integral type molding structure with base plate 2, and offer the first connecting hole of up/down perforation, offer second connecting hole corresponding with the first connecting hole on the upper cover plate 31 of rail pressing device, upper cover plate 31 is fixed to ground with base 32 snappings and by the bolt 4 that passes successively the first connecting hole and the second connecting hole.As can be known, in the utility model, every side of rail 1 in fact only need be rushed a through hole, the utility model can be fixed on the ground by a bolt 4, saved man-hour and cost, said further, through bolt 4 also more is conducive to be delivered to the impact force from rail 1 underground, thereby reduced by 1 pair of wearing and tearing of the present utility model of rail, reduced maintenance frequency.
Further, one end of upper cover plate 31 is provided with for the pressure head of compacting rail 1 with for the baffle plate that props up rail 1, and pressure head can directly be pushed down rail 1 as can be known, prevents that effectively it is up and down, baffle plate the bottom margin that can block rail 1 is set, prevent its move left and right.By the setting of upper cover plate 31 seaming chucks and baffle plate, effectively that rail 1 is fixing.Prevent that it from the up and down movement of direction occurring.
Please refer to Fig. 2 and Fig. 3, the top view of a kind of embodiment middle orbit fastening devices that Fig. 2 provides for the utility model; The lateral view of the device for fixing running tracks that Fig. 3 provides for Fig. 2.
In order further to optimize technique scheme, the track secure mounting arrangements that the utility model provides, the upper surface of the base 32 of its rail pressing device also is provided with the recessed slideway of the inclination that is positioned at the first connecting hole outside, ground matches with it, the soffit of upper cover plate 31 is provided with the boss slider that matches with recessed slideway, incline direction is for when boss slider is slided along recessed slideway, gradually near rail 1.Particularly, as shown in Figure 2, its incline direction of recessed slideway that is positioned on the base 32 on rail 1 right side is that right-to-left and this recessed slideway are positioned at the first connecting hole outside.As can be known, the bolt 4 that passes the second connecting hole and the first connecting hole has played fastening effect, directly provide upper cover plate 31 pairs of rail 1 downward active force, the cooperation of recessed slideway and boss slider then is used for overcoming the side-thrust of 1 pair of upper cover plate 31 of rail, the utility model with recessed installation of slide track the outside of the first connecting hole (take away from a side of rail as outside), so that stress point be positioned at bolt 4 the back (take away from a side of rail as after), so that bolt 4 is not subjected to the shearing force of horizontal direction, only play fastening effect, prolong the application life of bolt 4, reduced the number of times of maintenance.
Further, the upper surface of above-mentioned base 32 is inclined surface, and thickness reduces away from the side of the described recessed slideway of a side direction of described rail 1 near rail 1 gradually from recessed slideway.Namely when boss slider during along recessed slideway, upper cover plate 31 near rail 1, slides to lower from eminence gradually on the other hand on the one hand, and each step slides and sliding phenomenon can not occur back like this, namely this structure design has namely played the effect that prevents lateral force, has played again the effect of retaining simultaneously.
Please refer to Fig. 4 and Fig. 5, the top view of the another kind of embodiment middle orbit fastening devices that Fig. 4 provides for the utility model; The lateral view of the device for fixing running tracks that Fig. 5 provides for Fig. 4.
Be provided with a slideway on the base 32 of the rail pressing device among Fig. 2 and Fig. 3, be referred to as single slideway rail pressing device, in order further to strengthen the effect of above-mentioned rail pressing device, above-mentioned two single slideway rail pressing devices can be made one, i.e. Fig. 4 and two slideway rail pressing devices shown in Figure 5.Be to be provided with two slideways on the base 32, corresponding, the cooperation of two boss slider difference is arranged on the upper cover plate 31.
Strengthened like this fastening effect of rail pressing device to rail 1 so that fixing more difficult loosening to rail 1 of the utility model, be used for lifting larger hold car in the month, can effectively reduce maintenance frequency, reduce maintenance cost.
The utility model also comprises the rubber mat plate that meets that is arranged between rail 1 bottom and the base plate 2, so that rail 1 becomes flexible contact with contacting of base plate 2.Wearing and tearing have each other been reduced.
Each embodiment adopts the mode of going forward one by one to describe in this manual, and what each embodiment stressed is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
More than a kind of device for fixing running tracks provided by the utility model is described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
