Description
Technical field
The utility model is related to a kind of mining rail connection rail mouthpart.
Background technology
Mine rail is the key facility in Modern Pit transportation system, and it is responsible for heavy fortune coal and fortune spoil
Task.At present, joint uses seamed connection when mine rail is laid, and laying standard is：Down-hole main haulage roadway lays track
It is 30Kg/m and the track of the above that rail type, which must be used, and the rail type of the region such as inclined gallery and exploiting field laying track must not be less than 22Kg/
m.When track is connected, rail joint must use qualified road clamping plate, and be fixed with four bolts, and all rail joint spacing are not
5mm must be more than, just 2mm is cannot be greater than with left and right mismatch.When rail joint is using outstanding connect, 30Kg/m models railway sleeper is away from connecing
Head distance is 240mm, and deviation is no more than 240mm, and deviation is no more than 30mm, and 22Kg/m models railway sleeper is away from joint distance
220mm, deviation is no more than 30mm；When joint is using accepting, joint totally 3 sleepers, a middle joint in two tracks,
Another two respectively away from middle sleeper 240mm（30Kg/m tracks）, 220mm (22Kg/m), straightway should dock, and mistake is away from little relatively
In 50mm, curved section answers misconnection, and corresponding mistake is away from not less than 2m.But due to the presence of rail gap, wheel connects with rail gap in transportation
Tactile moment can produce huge percussion and noise, and the service life of reduction locomotive, mine car and track adds the maintenance of track
Cost；When rail gap is exceeded and during joint out-of-flatness, occurs in car-haul and hangs phenomenon, huge peace is brought to coal production
It is complete to threaten.
With the development of technology, being seamlessly connected turns into the trend that future track is connected, such as Publication No.
CN101177924A Chinese invention patent application discloses a kind of noise elimination rail joint, it is characterised in that the joint system of track
Identical grafting joint or many identical grafting joints of broken line reply of angle is tackled into angle, and installs solid with joint steel plate and screw
It is fixed to constitute.This invention eliminates joint lateral clearance breaking joint on track road surface, makes to alternate between two rail joints to scoop out,
The noise for reducing the percussion in wheel and rail joint gap and producing, but relatively difficult and grafting when processing of many broken line joints
The problem of easily there is out-of-flatness in joint, rail gap is uneven.
Utility model content
The purpose of this utility model is to provide a kind of mining rail connection rail mouthpart, when being seamlessly connected to solve track
The problem of out-of-flatness occurs in rail joint, rail gap is uneven, reduces rail gap welding difficulty, improves operating efficiency.
To achieve the above object, the utility model is adopted the following technical scheme that：A kind of mining rail connects rail mouthpart, including
Pressing plate, includes offering the first connecting hole, the one of the pressing plate on the base of supporting track interface, the upper surface of the base
Side offers the second connecting hole corresponding with the first connecting hole, and the bottom surface of the pressing plate opposite side is provided with matches somebody with somebody with track lower inclined plane
The bolt that bottom plate is compressed and is packed on base is combined with the mating surface of conjunction, first and second connecting hole.
Described base is in " work " font, including centerbody, epipleural and lower side panel, the upper and lower side of centerbody respectively with it is upper
Side plate, lower side panel are fixedly connected, and the first described connecting hole is opened at the two ends of the epipleural, and the first connecting hole is symmetrically in distribution.
The two ends of the Its lower side plate offer fixing hole.
The beneficial effects of the utility model：Two rail joints to be welded are positioned on bottom plate, and with pressing plate by two
Rail joint is pressed on base, it is ensured that two rail joints are smooth, and rail gap is uniformly neat, is easy to seamless welding, is improved work
Efficiency.

Embodiment
The utility model mining rail connects the embodiment of rail mouthpart, as shown in Figures 1 to 6, including pressing plate 4 and supporting rail
The base of pipeline joint, the upper surface of base is provided with the first connecting hole 7, and the side of pressing plate 4 offers corresponding with the first connecting hole 7
Second connecting hole 8, the bottom surface of the opposite side of pressing plate 4 is provided with the mating surface coordinated with track lower inclined plane, first and second connecting hole
7th, the bolt that pressing plate 4 is compressed and is packed on base is combined with 8.In embodiment, base be in " work " font, including centerbody 1,
Epipleural 3 and lower side panel 2, epipleural 3 are welded on the upper end of centerbody 1, and lower side panel 2 is welded on the lower end of centerbody 1, epipleural
The first connecting hole 7 that 3 two ends are opened up, the first connecting hole 7 is symmetric, and the first connecting hole 7 is connected with second on pressing plate 4
8 holes are corresponded to up and down.Certainly, in other embodiments, the shape of base is unrestricted, such as base can be cube type or circle
Column type.
In addition, opening up fixing hole 6 at the two ends of lower side panel 2, so that base is fixed on ground basal plane, prevent base from tilting
Collapse the actual bodily harm caused to staff.
Base when in use, is fixed on straight ground basal plane by above-described embodiment first with bolt, being welded
The first rail joint 9 and the second rail joint 10 be positioned on base, and the vertical center line of rail gap and base is protected substantially
Hold on one wire, the second connecting hole 8 on pressing plate 4, the first connecting hole 7 on base are then sequentially passed through using bolt 5, will
Two tracks connect 9,10 and are pressed on base.
