Abstract

The utility model discloses a wood sleeper rail fixed by bolt press plate, belonging to mining machinery. Two bolt holes which are used for placing bolts are respectively opened on two ends of the wood sleeper for lying a steel rail, the bottom of the bolt holes are square or polygon counter-bores which are matched with a bolt head. Bolts which are passed into the bolt holes from the bottom of the wood sleeper and a steel cushion plate which is arranged under the steel rail on the wood sleeper are also included, holes which can be passed by two bolts are opened on the steel cushion plate, the bottom of the steel rail is placed on the steel cushion plate and is pressed tightly and fixed by a steel press plate and nuts which are passed through by the two bolts. The utility model has the beneficial effects that the structure is reliable, the fixation of the steel rail is firm, and the using effect is good.

Description

The fixed wooden sleeper track of bolt clip plate

Technical field

The utility model relates to a kind of mining machinery, specifically is the fixed wooden sleeper track of a kind of bolt clip plate.

Background technology

The mine rail transportation be unable to do without sleeper.Sleeper is rail " pillow ", is used for bearing the pressure of rail, and transfers the pressure to ballast aggregate and get on, and keeps the gauge of two rail simultaneously, prevents that track from moving.Sleeper has wooden and two kinds of steel concrete.Wooden sleeper is that various countries' railway adopts the earliest, and a kind of sleeper that is still generally adopted up till now.For a long time, be rail, backing plate and wooden sleeper to be nailed together with railway spike.The shortcoming of this structure is:

1), rail be subjected to load and on railway spike is floated when scratching.

2), be subjected to the extruding of train lateral force, gauge is difficult for keeping.

3), do not hole easy splitting when directly pounding railway spike in advance.

4), railway spike bows, faces upward, askew, skew, floating, from, mill, curved " eight evils ", maintenance capacity is big, the expense height.

In the past,,, threatened traffic safety, influenced requisite quality so the ubiquity railway spike lost efficacy, the super wide problem of gauge because the exploiting field track all is to adopt the fixed wooden sleeper of railway spike.

Summary of the invention

The purpose of this utility model is in order to overcome the above-mentioned shortcoming of the fixed wooden sleeper of railway spike, to provide a kind of bolt clip plate fixed wooden sleeper track.Fundamentally solve railway spike float inefficacy, gauge super wide, threaten traffic safety, influence the requisite quality problem.

The utility model is realized with following technical scheme: the fixed wooden sleeper track of a kind of bolt clip plate, comprise wooden sleeper, the rail of accumbency on wooden sleeper, it is characterized in that the rail place of putting for sleeping in respectively has two bolts hole of placing bolts at the both ends of wooden sleeper, the bottom of bolt hole is the square or polygonal counterbore that matches with bolt head; Also comprise the bolt that bottom wooden sleeper, penetrates the bolt hole, be placed on the wooden sleeper below the rail billet, having two on the billet can be for two hole that bolt passes, and crouches to be put on the billet and by being through two keeper plate of steel and nuts on the bolt and be fixed in the bottom of rail.

Can also place the rail place at billet and be provided with the groove that card is put rail, crouch to be put in the groove and by being through two keeper plate of steel and nuts on the bolt and be fixed in the bottom of rail.

The beneficial effects of the utility model are: rational in infrastructure, and the rail fixation, result of use is good.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the utility model overall structure schematic diagram;

Fig. 2 is the partial enlarged drawing of Fig. 1.

Among the figure: 1, wooden sleeper, 1-1, bolt hole, 1-2, counterbore, 2, bolt, 3, billet, 4, keeper plate of steel, 5, nut, 6, rail.

The specific embodiment

As depicted in figs. 1 and 2, comprise wooden sleeper 1, the rail 6 of accumbency on wooden sleeper, wooden sleeper 1 long 1200mm, wide 160mm, high 140mm.Crouch at the both ends of wooden sleeper and to put the rail place and respectively have two bolt hole 1-1 that place bolts, the spacing between two bolt hole external diameters equals the width of rail 6 bottoms.The bottom of bolt hole is the square or polygonal counterbore 1-2 that matches with bolt head; Bolt 2 penetrates the bolt hole from the wooden sleeper bottom, lay billet 3 below the rail on wooden sleeper, having two on the billet can be for two hole that bolt 2 passes, and crouches to be put on the billet 3 and by being through two keeper plate of steel 4 and nuts 5 on the bolt 2 and be fixed in the bottom of rail 6.

Also can have the groove that card is put rail at the placement rail place of billet 6, the wide 94mm of groove, crouch and be put in the groove in the bottom of rail 8, fit on keeper plate of steel 4, the keeper plate of steel inclined-plane is consistent with rail bottom side gradient.Be fixed by the nut 5 on two bolts 2.Bolt 2 is square toes or polygonal hook bolt, is difficult for rotating.

Claims

1, the fixed wooden sleeper track of a kind of bolt clip plate, comprise wooden sleeper (1), the rail (8) of accumbency on wooden sleeper, it is characterized in that the rail place of putting for sleeping in respectively has two bolts hole (1-1) of placing bolts at the both ends of wooden sleeper, the bottom of bolt hole is the square or polygonal counterbore (1-2) that matches with bolt head; Also comprise the bolt (2) that bottom wooden sleeper, penetrates the bolt hole, be placed on the wooden sleeper below the rail billet (3), have two holes that can supply two bolts (2) to pass on the billet, the bottom of rail (6) billet (3) that is put in for sleeping in is gone up and is fixed by the keeper plate of steel (4) and the nut (5) that are through on two bolts (2).

2, the fixed wooden sleeper track of bolt clip plate according to claim 1, it is characterized in that placing rail (6) at billet locates to be provided with the groove that card is put rail, crouches to be put in the groove and by the keeper plate of steel (4) and the nut (5) that are through on two bolts (2) and is fixed in the bottom of rail (6).

3, the fixed wooden sleeper track of bolt clip plate according to claim 1 is characterized in that bolt (2) is square toes or polygonal hook bolt.
