Embodiment

The utility model is introduced below by way of accompanying drawing.It should be noted that it is only for explanation that these, which are introduced, Principle of the present utility model and provide, be not so limited the scope of the utility model.

Fig. 1 and 2, which respectively illustrates, to be applied to tunnel according to fixed track usage plan device 100 of the present utility model and refoots the bowing of operation View and front view.As illustrated in fig. 1 and 2, crossbeam 110 is mainly included according to fixed track usage plan device 100 of the present utility model and is indulged Beam 120.Wherein, some crossbeams 110 are set up in the lower section of rail 20 in a manner of parallel to each other and be spaced apart, for by rail 20 support.So, sleeper (not shown) can be extracted out from the lower section of rail 20.Spacing between adjacent two crossbeams 110 can Selected according to actual conditions and experience, the total quantity of crossbeam 110 can select according to the length of operation interval.

Fixed track usage plan device 100 also includes two longerons 120, and they are in a manner of parallel to each other and be spaced apart in each horizontal stroke The end of beam 110 is set up on crossbeam 110.That is, the base 121 (see Fig. 4) of longeron 120 and the top of crossbeam 110 Side 111 fits (see Fig. 3).As shown in Fig. 2 the both ends of crossbeam 110 usually extend to the drainage channel 50 of the both sides of rail 20 Opening position, drainage channel 50 is interior to be filled and led up (shown in the black bars in Fig. 2) by irrigating slurry.Therefore, two longerons 120 are distinguished It is roughly parallel to the drainage channel 50 of the both sides of rail 20 and extends.

So, intersecting the fixed track usage plan device 100 formed by two longerons 120 and some crossbeams 110 can be effectively Aerial rail 20, total have very high rigidity so that train 10 (schematically showing in fig. 2) can safely pass through Rail 20.At the same time, region 30 can be removed to the inverted arch filling below rail 20 and inverted arch is removed region 31 and operated.

Fig. 3 shows the cross-sectional view of the crossbeam 110 according to fixed track usage plan device 100 of the present utility model.Such as Fig. 3 institutes Show, crossbeam 110 is H profile steel, I-steel or welding shaped steel.In a specific embodiment, crossbeam 110 employ HN300 × 200 type H profile steels, length are 4.4 meters.

Fig. 4 shows the cross-sectional view of the longeron 120 according to fixed track usage plan device of the present utility model.As shown in figure 4, Longeron 120 includes two I-steel being arranged in juxtaposition, I-steel or welding shaped steel.In a specific embodiment, longeron 120 Employ two 45b being arranged in juxtaposition type I-steel.Longeron 120 is erected at the end region of crossbeam 110, parallel to track 20 And extend.Because longeron 120 is directly erected at the top of crossbeam 110, therefore after the laying of crossbeam 110 is completed, can facilitate Longeron 120 is installed on ground, is avoided caused because of installing space when longeron is installed on below the crossbeam (such as in drainage channel) It is narrow and cause the problem of inconvenient for operation.

In order to which longeron 120 is erected on crossbeam 110 securely, according to the utility model, there is provided one kind is used for line The fixation kit 130 that the crossbeam 110 and longeron 120 of road overhead device 100 are fixed together.As it can be seen in figures 5 and 6, fixation kit 130 include buckle 131 and U bolt 132.It should be noted that show in figs. 5 and 6 for being matched with U bolt 132 The nut used, but in view of the pairing use of nut and bolt is known in the art, therefore for the sake of simplifying length, Nut is considered as a part for U bolt herein and is no longer individually described.That is, U bolt 132 includes The matched nut used.

Show the front view and top view of the buckle 131 of fixation kit 130 respectively in figures 7 and 8.As illustrated, button Plate 131 is formed approximately in the part of a shape of a saddle, including horizontal bottom 135, and substantially perpendicular from the both ends of bottom 135 Two vertical portions 136 directly to extend out.The free end of two vertical portions 136 is respectively along opposite horizontal direction to overhanging Go out, form two horizontal fixed parts 137.Fixing hole 138 is provided with each fixed part 137.In addition, the two of fixed part 137 Individual side is each formed with ribs 139, and it connects each fixed part 137 and corresponding vertical portion 136, there is provided increases Strong rigidity.Ribs 139 is for example configured to triangle.

Referring again to Fig. 5 and 6, according to the utility model, two U bolts 132 are arranged in the both sides of longeron 120, And crossbeam 110 is contained in its inner chamber.This is especially clearly shown in Fig. 6 section below.Preferably, crossbeam 110 Base 112 (see Fig. 3) and the base of U bolt 132 fit, and the width of the inner chamber of U bolt 132 is substantially equal to crossbeam 110 width.Thereby it is ensured that crossbeam 110 can be connected by form fit to be securely arranged in U bolt 132.

Two buckles 131, which are spaced, turns up the soil by its inner chamber to be fastened on longeron 120, and its spacing is substantially equal to U-shaped The spacing at the both ends of bolt 132.The both ends of U bolt 132 are each passed through the fixing hole 138 on two buckles 131, and utilize nut Fastening.

In one embodiment, the height of the vertical portion 136 of the depth of the inner chamber of buckle 131, i.e. buckle 131 is chosen to locate In longeron 120 height a quarter in the range of 1/3rd.Set by this size, can more efficiently from Longeron 120 is fixed in top.

Pass through fixation kit 130, it is possible to longeron 120 is securely fixed on crossbeam 110, is effectively improved whole The rigidity of fixed track usage plan device 100, ensure that train by when security.

In a preferred embodiment, fixation kit 130 is arranged so that the connection of two longitudinally adjacent longerons 120 Portion is in the inner chamber of U bolt 132.So, the firm of the connecting portion of two longitudinally adjacent longerons 120 is further ensured Property.

In a preferred embodiment, also included being arranged on each according to fixed track usage plan device 100 of the present utility model Rail distance rod (not shown) between longeron 120 and that adjacent root rail 20.Rail distance rod is that those skilled in the art institute is ripe Know, its specific descriptions is omitted here.Thus, it is possible to ensure the distance between each longeron 120 and that adjacent root rail 20 perseverance It is fixed, further ensure train by when security.

According to fixation kit of the present utility model, the crossbeam in fixed track usage plan device and longeron can be fixed on securely Together so that fixed track usage plan device makes somebody a mere figurehead rail with disclosure satisfy that requirement, so as to ensure train safety, while can be square Just the operation that refoots is carried out.

Finally it should be noted that the foregoing is only preferred embodiment of the present utility model, do not form to this Any restrictions of utility model.Although the utility model is described in detail with reference to foregoing embodiments, for For those skilled in the art, the technical scheme described in previous embodiment can still be modified, or to wherein Some technical characteristics carry out equivalent substitution.All any modifications within the spirit and principles of the utility model, made, equally replace Change, improve, should be included within the scope of protection of the utility model.
