Abstract
The utility model disclose a railway sleeper bar, which is a groove track bar of a reversal 'U' form on the transect, which comprises an upper wall, a couple of side walls and a couple of ends; the upper wall is roughly horizontal with three fastening hole groups arranged, a groove containing steel track is formed between the fastening hole group, the distance between the fastening holes at the two ends is fitted with the broad gauge train, the distance between the fastening hole group in the middle and one of the other two hole group is fitted with the narrow gauge train, wherein the groove leans inward and upward, the leaning angle is 1:20. The utility model is a design of mixed track, steel track of two gauges can be paved on the steel bar, which largely reduces the materials and fees of paving the train and reduces the occupying space of the trains, at the same time, the leaning angle of the groove for the steel track placed on the steel bar is improved, which can make the steel track be stressed more evenly to decrease the abrasion wear of the top of the steel track and increase the bearing ability of the steel track.
Description
Technical field
The utility model relates to the sleeper of railway track, particularly a kind of railway steel sleeper.
Background technology
The sleeper material that extensively adopts on the railway is three kinds now: wooden sleeper, concrete sleeper and steel sleeper.Cheap wooden sleeper and the concrete sleeper of the general employing of China.Tong Hang sleeper is the steel sleeper of regulation in " International Union of Railways " in the world, and the reliability of steel sleeper is better than wooden sleeper and concrete sleeper.This steel sleeper is made up of pair of sidewalls and a upper wall, and its cross section is inverted U basically, end sealing, and the upper wall approximate horizontal has the fastener hole group at each position that rail is installed on the upper wall, is used for being connected with the fixing shoulder pad of rail.Position from-inner-to-outer between the fastener hole group is inclined upwardly, and the angle of inclination was generally 1: 40.Prove that through long-term use this angle of inclination is unreasonable, especially when load-carrying was big, the abrasion at rail top were comparatively serious.In addition, the historical in the world train that gets off to have broad gauge and two kinds of different gauges of narrow gauge that follows, the railway that therefore needs to lay two kinds of gauges could adapt to the travelling of train of different size, have consumptive material, consume the phenomenon of the wastings of resources such as ground.
The utility model content
Technical problem to be solved in the utility model provides a kind of railway steel sleeper, improve the gradient of the sidewall that contacts with rail, increased the lifting capacity of rail, reduced the top loss of rail, and wide, narrow two kinds of rail can be set on a kind of steel sleeper, save material and space.
For addressing the above problem, technical solution adopted in the utility model is: a kind of railway steel sleeper, for the cross section is the slot type sleeper of inverted U basically, comprise a upper wall, pair of sidewalls and pair of end portions, the upper wall approximate horizontal, upper wall is provided with the fastener hole group, position between the fastener hole group forms the groove of ccontaining rail, described fastener hole group is three groups, be positioned at the distance and broad gauge train coupling of the fastener hole group at two ends, the distance of one of the fastener hole group in the middle of being positioned at and other two groups of fastener hole groups is mated with narrow-gauge train.
Wherein, described groove is inclined upwardly from inside to outside, and the angle of inclination is 1: 20.
The beneficial effect that the utility model can reach is:
1. the utility model can be laid the rail of two kinds of gauges for mixing the rail design on a steel sleeper, has saved the material and the expense that place an iron railway greatly, and has reduced the shared space of railway.
2. the utility model has improved the angle of inclination of placing the groove of rail on the steel sleeper, makes the stressed more even of rail, has reduced the abrasion at rail top, has increased the supporting capacity of rail.

The specific embodiment
Consult Fig. 1～3, be the schematic diagram of a kind of railway steel sleeper of the utility model embodiment.The utility model is the improvement design of carrying out on the general steel sleeper basis of International Union of Railways.This railway track is a kind of slot type sleeper, comprise a upper wall 1, pair of sidewalls 2 and pair of end portions 3, upper wall 1 approximate horizontal, upper wall 1 is provided with three groups of fastener holes 4,5,6, the fastener hole group is used for being connected with the fixing shoulder pad of rail, wherein is positioned at the distance and the broad gauge train coupling of the fastener hole group 4,6 at two ends, and the fastener hole group 5 in the middle of being positioned at is mated with narrow-gauge train with the distance of left side fastener hole group 4.The fastener hole group of existing sleeper is also slightly different according to the difference of shoulder pad, but generally comprise two holes 41,42 of mating at least with the rail width, position between the hole 41,42 forms the groove 7 of ccontaining rail, groove 7 towards close end be inclined upwardly from inside to outside, the angle of inclination is 1: 20, this angle of inclination can make the impact minimum of train to the rail top, reduces the abrasion of rail.
Claims (2)
1, a kind of railway steel sleeper, for the cross section is the slot type sleeper of inverted U basically, comprise a upper wall, pair of sidewalls and pair of end portions, upper wall approximate horizontal, upper wall is provided with the fastener hole group, position between the fastener hole group forms the groove of ccontaining rail, it is characterized in that, described fastener hole group is three groups, be positioned at the distance and broad gauge train coupling of the fastener hole group at two ends, the distance of one of the fastener hole group in the middle of being positioned at and other two groups of fastener hole groups is mated with narrow-gauge train.
