Abstract
The utility model discloses the universal concrete for mines sleepers in bolt clip plate formula curved straight road, it include concrete sleeper, concrete sleeper both ends are embedded with outside bolt, inside bolt respectively, pressing plate, nut are separately installed on outside bolt, inside bolt, pressing plate on outside bolt, inside bolt is pressed on rail base wing plate respectively, pressing plate has the step surface to match with rail base, is provided with the bolt hole to match with outside bolt, inside bolt on pressing plate.The utility model can be adapted for the straight rail or bending track road in mine, reduce operational procedure, while reducing labor intensity of workers.
Description
Technical field
The utility model relates to mine rail fields, particularly belong to the universal concrete for mines rail in bolt clip plate formula curved straight road
Pillow.
Background technique
Mine rail transport is underground mining mine prevailing traffic mode, the capital equipment of rail transport have track, mine car,
Pulling equipment, sleeper, mine car are divided into cargo transport mine car, people's vehicle and Special mine car by purposes.The gauge of general mine rail is divided into
900mm,600mm.Traditional sleeper production cost is bigger, is reserved with bolt hole on sleeper, the bad control of the size of bolt hole,
The general aperture using bolt hole is reserved big, but stability will be deteriorated, and bolt is easily lost.When encountering bending track road
When, gauge should slightly be widened, and the position mounting and adjusting of track is cumbersome.
Utility model content
The purpose of the utility model is to provide a kind of universal concrete for mines sleeper in bolt clip plate formula curved straight road, Ke Yishi
For the straight rail or bending track road in mine, operational procedure is reduced, while reducing labor intensity of workers.
Technical solution used by the utility model is as follows:
The universal concrete for mines sleeper in bolt clip plate formula curved straight road includes concrete sleeper, concrete sleeper both ends
It is embedded with outside bolt, inside bolt respectively, is separately installed with pressing plate, nut on outside bolt, inside bolt, outside bolt,
Pressing plate on the bolt of inside is pressed on rail base wing plate respectively, and pressing plate has the step surface to match with rail base, pressing plate
On be provided with the bolt hole to match with outside bolt, inside bolt.
Spacing is a between the step surface and bolt hole center's line of pressing plate on the outside bolt, the pressure on the bolt of inside
Spacing is b, a ≠ b between the step surface and bolt hole center's line of plate.
The track is located at straight line, and a > b；Track is located at turning, and the pressing plate on outside bolt, inside bolt is mutual
It exchanges, and a > b, the track of two sides are displaced outwardly respectively.
Gasket is equipped between the outside bolt, pressing plate and nut on the bolt of inside.
At concrete sleeper both ends, backing plate, bolt, nut will not for the outside bolt of the utility model, inside bolt embedment
It loses, and stability is good.When track is located at straight line, and a > b；When track is located at turning, on outside bolt, inside bolt
Pressing plate is mutually exchanged, and the track of two sides is displaced outwardly respectively, and a > b, so that gauge be widened in right amount, while meeting mine straight rail
The gauge requirement in road or bending track road reduces operational procedure, avoids gauge error, while reducing labor intensity of workers.
It is as follows that preformed is changed to built-in type advantage by the utility model: 1), ensuring gauge, the gauge point of general mine rail
For 900mm, 600mm.2) process, is reduced.3) parts such as backing plate, bolt, nut, is avoided to lose.
Detailed description of the invention
Fig. 1 is that the utility model track is located at the scheme of installation at straight line.
Fig. 2 is the scheme of installation that the utility model track is located at turning.
Specific embodiment
Referring to attached drawing, the universal concrete for mines sleeper in bolt clip plate formula curved straight road, includes concrete sleeper 1, coagulation
Native 1 both ends of sleeper are embedded with outside bolt 2, inside bolt 3 respectively, are separately installed with pressing plate on outside bolt 2, inside bolt 3
4, nut 5, the pressing plate 4 on outside bolt 2, inside bolt 3 are pressed on 6 bottom flap of track respectively, and pressing plate 4 has and track 6
The step surface 7 that bottom matches is provided with the bolt hole 8 to match with outside bolt 2, inside bolt 3 on pressing plate 4；Outside bolt 2
On pressing plate 48 center line of step surface 7 and bolt hole between spacing be a, the step surface 7 and spiral shell of the pressing plate 4 on inside bolt 3
Spacing is b, a ≠ b between 8 center line of keyhole；Track 6 is located at straight line, and a > b；Track 6 is located at turning, outside bolt 2,
Pressing plate 4 on inside bolt 3 is mutually exchanged, and a > b, the track 6 of two sides are displaced outwardly respectively；Outside bolt 2, inside bolt 3
On pressing plate 4 and nut 5 between be equipped with gasket 9.
