Abstract
The utility model discloses a concrete sleeper for coal mine. Two rail support grooves are respectively arranged on the surfaces of the two ends of the sleeper body, the bottom surface of each rail support groove is an inclined bottom surface which is externally high and internally low, the inclination of the bottom surface is 1:20-40, two bolt holes penetrating the sleeper body vertically are arranged on the bottom surface of each rail support groove, and the two bolt holes are respectively arranged on the inside and the outside of the bottom surface of each rail support groove for bolts and fasteners to easily fix the rail from inside and outside. The utility mode which has simple structure, reasonable design and capability of reducing wear between rail and wheel, prolonging service life and reducing maintenance frequency is widely applicable to rail laying for coal mine with good economic benefit.
Description
One, technical field:
The utility model relates to a kind of guiding device, particularly relates to a kind of colliery new type concrete sleeper.
Two, background technology:
As everyone knows, mine car is adopted in the transportation of material more in the colliery, and mine car is the wheel-track type structure mostly, need on supply line, lay track, wherein sleeper is the key that guarantees the track normal transport, concrete sleeper is adopted in the colliery more at present, find its poor effect in using at the scene, be embodied in: the support rail platform of attachment rail is the plane on the sleeper, thereby makes the last contact surface of track also be the plane, causes track and wheel wear excessive, particularly show more very at the turning, it is right to need often to change track and vehicle wheel, waste of manpower, material resources, and influence conevying efficiency, strengthen operation cost, in addition, also there is the fastening bolt excesssive gap that moves about in existing sleeper, and causes gauge to change and is difficult to control; Strength deficiency; Each sharp edge all is the right angle, causes the corner to come off easily and influences defectives such as attractive in appearance.
Three, the content of utility model:
The purpose of this utility model: overcome the defective of prior art, provide a kind of simple in structure, reasonable in design, can reduce abrasion between track and the wheel, long service life and reduce the colliery new type concrete sleeper of frequency of maintenance.
The technical solution of the utility model: a kind of colliery new type concrete sleeper, contain the sleeper body, be respectively arranged with a support rail groove on the two ends upper surface of described sleeper body, the bottom surface of described each support rail groove is high outside and low outside ramped bottom surface, the gradient of described bottom surface is 1: 20～and 40, and be provided with the bolt hole that vertically runs through the sleeper body on the bottom surface of described each support rail groove, be convenient to bolt and fastener trapped orbit.
The bottom surface gradient of described each support rail groove is 1: 40.Perhaps, the bottom surface gradient of described each support rail groove is 1: 30.Perhaps, the bottom surface gradient of described each support rail groove is 1: 25.Perhaps, the bottom surface gradient of described each support rail groove is 1: 35.
Two bolts hole all are set on the bottom surface of described each support rail groove, and two bolts hole lay respectively at the inside and outside both sides of each support rail groove floor, be convenient to bolt and fastener from inside and outside both sides trapped orbit.
The beneficial effects of the utility model:
1, the utility model can reduce abrasion, the long service life between track and the wheel and reduce frequency of maintenance, because the bottom surface of the support rail groove that is provided with respectively on the two ends upper surface of sleeper body is high outside and low outside ramped bottom surface, make the track of installation also inclined, reduce wear particularly reduces the wearing and tearing when turning so greatly, in the application life of advancing the track and wheel, improve economic benefit of enterprises.
2, the utility model is simple in structure, processing easily, cost is lower, be provided with inside and outside two bolts hole in its support rail groove, be convenient to bolt and fastener from inside and outside both sides trapped orbit, reduce the variation of gauge, thereby reduce the flank wear of track and wheel, also can prevent from simultaneously to change the situation of the stuck wheel of track that causes too greatly, use very convenient because of gauge.
3, the utility model design has special-purpose support rail groove, fastener is clamped in the groove, and the diameter dimension and the symmetrical size of appropriate design sleeper T type bolt penetration hole, thereby reduce the bolt free movement greatly, guarantee the uniformity of gauge, in addition, increase the width and the height of original sleeper and adopt high-grade concrete and major diameter skeleton reinforcing steel bar, to improve its intensity; Simultaneously fillet is all made at all sharp comer places of sleeper, improved intensity, also strengthen aesthetic.
4, the utility model scope of application is wide, is particularly useful for the track laying of colliery material transportation, is easy to promote, and has favorable economic benefit.
Four, description of drawings:
Fig. 1 is the structural representation of colliery with new type concrete sleeper;
Fig. 2 is the left view of colliery shown in Figure 1 with new type concrete sleeper;
Fig. 3 is the scheme of installation of colliery shown in Figure 1 with new type concrete sleeper and track.
Five, the specific embodiment:
Embodiment one: referring to Fig. 1, Fig. 2, Fig. 3, among the figure, be respectively arranged with a support rail groove 2 on the two ends upper surface of colliery with the sleeper body 3 of new type concrete sleeper, the bottom surface of two support rail grooves 3 is high outside and low outside ramped bottom surface, its gradient is 1: 40, and be provided with two bolts hole 1 that vertically run through sleeper body 3 on the bottom surface of each support rail groove 3, and two bolts hole 1 lay respectively at the inside and outside both sides of each support rail groove 3 bottom surface, are convenient to bolt 4 and fastener 5 from inside and outside both sides trapped orbit 6.
Because the bottom surface of support rail groove 3 is high outside and low outside ramped bottom surface, makes the track 6 of installation also inclined, reduce wear particularly reduces the wearing and tearing when turning so greatly, in the application life of advancing the track and wheel, improves economic benefit of enterprises.In addition, fastener 5 is clamped in the support rail groove 2, and the diameter dimension and the symmetrical size in appropriate design sleeper T type bolt-through hole 1, thereby reduce bolt 4 free movements greatly, guarantee the uniformity of gauge.
Embodiment two: present embodiment and embodiment one are basic identical, and something in common does not repeat, and difference is: the bottom surface gradient of each support rail groove is 1: 30.
Embodiment three: present embodiment and embodiment one are basic identical, and something in common does not repeat, and difference is: the bottom surface gradient of each support rail groove is 1: 25.
Embodiment four: present embodiment and embodiment one are basic identical, and something in common does not repeat, and difference is: the bottom surface gradient of each support rail groove is 1: 20.
Change the concrete numerical value of gradient, for example 1: 22,1: 28,1: 35,1: 38 etc., can form a plurality of embodiment, be the common excursion of the utility model, do not describe in detail one by one at this.
