Railway track displacement monitoring fixture
The utility model relates to the attached of measuring equipment and helps device, relates to fixture, particularly relates to a kind of railway track displacement monitoring fixture.
At present, fixture railway track being installed the displacement meter use for monitoring relative displacement between rail and track plates is normally welded on rail foot.The field monitoring displacement meter welded and installed mode practical operation of this steel rail displacement of prior art is inconvenient, and can produce damage to rail and cannot reuse fixture, this be its shortcoming.
[summary of the invention]
For the shortcoming of prior art, the purpose of this utility model is to provide a kind of structure simple, easy for installation, reliable and safety, can not to rail produce damage be easy to realize the debugging of displacement meter and the railway track displacement monitoring fixture of dismounting.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of railway track displacement monitoring fixture, there is the profile of a class cuboid, it is characterized in that: there is a recess described fixture side, recess form makes according to size at the bottom of Rail, and this recess and rail base plate match and rail bottom panel side can be embedded in this recess; There is screw the top of described recess, and this screw and screw match and be fixed on rail by fixture; There is pass through aperture the below of described recess, for connecting and be fixedly sandwiched in two fixtures of rail both sides.
Can structure grooves be had in the middle of the top of described recess, the top of recess is divided into two joints, often joint have a screw.
Can there be displacement meter connecting hole the below of described recess in the top of through hole 32.Be connected with displacement meter to facilitate.
Described fixture can make of aluminium alloys.
During use, rail base plate is embedded in two symmetrical fixtures placed, the through hole of screw rod through two fixtures, fix with nut screwing clamping, and make clamp on rail with two screws.Fixture is installed relevant displacement meter, can steel rail displacement monitoring be carried out.
The beneficial effects of the utility model are: simple, easy for installation, the reliable and safety of structure, can not produce damage, be easy to the debugging and the dismounting that realize displacement meter to rail.

[detailed description of the invention]
See accompanying drawing, a kind of railway track displacement monitoring of the utility model fixture, has the profile of a class cuboid, it is characterized in that: there is a recess 31 described fixture side, and this recess 31 matches can embed in this recess by rail 1 bottom panel side with rail 1 base plate; There is screw 33 top of described recess 31, and this screw and screw 2 match and be fixed on rail by fixture 3; There is pass through aperture 32 below of described recess 31, for connecting and be fixedly sandwiched in two fixtures of rail both sides.
In embodiment of the present utility model:
There is structure grooves 34 in the middle of the top of described recess 31, the top of recess 31 is divided into two joints, often joint has a screw 33.
There is displacement meter connecting hole 35 below of described recess 31 in the top of through hole 32.For being connected with displacement meter.
Described fixture aluminium alloys makes.
During use, rail 1 base plate is embedded in two symmetrical fixtures 3 placed, the through hole 32 of screw rod 4 through two fixtures, tighten fixing with nut 5,7, and make clamp on rail 1 with two screws 2.Fixture is installed relevant displacement meter, can steel rail displacement monitoring be carried out.
