Description
Technical Field
The utility model relates to the technical field of steel rails, in particular to a railway steel rail profile ruler.
Background
The high-speed railway, called high-speed railway for short, is a railway with high infrastructure design speed standard and capable of providing safe high-speed running of trains on the railway, the train operation speed is more than 200km/h, the existing high-speed railway comprises two parallel steel rails, the steel rails are fixedly placed on sleepers, ballast is arranged below the sleepers, the trains repeatedly roll the steel rails at high speed for a long time, the abrasion and plastic deformation of the rail surfaces of the steel rails can be caused, meanwhile, nonstandard flash can appear on the inner sides of the heads of the steel rails, particularly, turnouts and curve sections are serious, the flash of the steel rails not only accelerates the abrasion of wheels, but also reduces the service life of the wheels, and simultaneously increases the reactive energy consumption of locomotive traction, so that the steel rails need to be replaced after being used for a long time.
The cost of the steel rail in the high-speed railway track is high, so the cost of repairing the high-speed railway track through replacement is also high, in fact, the flash on the steel rail can be repaired through polishing, the steel rail after being polished and repaired is capable of being used continuously, therefore, a detection tool is needed to detect whether the steel rail meets the operation design requirements, the detection is mostly carried out through a profile ruler at present, each curved surface of the steel rail is detected through the profile ruler, the profile ruler is mostly placed on the steel rail in a hand-held mode at present, the detection is directly influenced if the manual placement position is inaccurate, the whole length direction needs to be detected due to the fact that the steel rail is longer, the manual taking and placing efficiency is low, in addition, the profile ruler is mostly provided with a corresponding detection curved surface on one side, the profile ruler with a corresponding size is matched with different steel rails, and based on the defects and the defects, the existing technology needs to be improved, a railway steel rail profile ruler is designed.
SUMMERY OF THE UTILITY MODEL
The utility model mainly solves the technical problem of providing the railway steel rail profile ruler which is simple in structure, ingenious in design, convenient to operate, multipurpose and capable of being compatible with two types of steel rails simultaneously, and cost is saved.
In order to solve the technical problems, the utility model adopts a technical scheme that: the utility model provides a railway rail profile chi, this kind of railway rail profile chi includes telescopic link, supporting wheel, profile chi mount pad, profile chi body and cushion, the supporting wheel is installed to the telescopic link afterbody, the flexible head of telescopic link is fixed with the profile chi mount pad, the profile chi mount pad stretches out the end and is provided with vertical mounting plane, installs the profile chi body on the mounting plane, both sides are provided with the rail profile who detects two kinds of specification rails about the profile chi body, and rail profile department mark is equipped with the scale mark, and a chi is dual-purpose, the profile chi mount pad stretches out the end rear side and clamps the cushion that is used for supporting.
Preferably, the profile ruler body is made of 304 stainless steel.
Preferably, the supporting wheel is made of nylon, is light and convenient, and does not damage the steel rail in the detection rolling process.
Compared with the prior art, the utility model has the beneficial effects that:
simple structure, design benefit, the operation of being convenient for, a chi is multi-purpose, can compatible two kinds of rail simultaneously, practices thrift the cost.

Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and will thus define the scope of the utility model more clearly and clearly.
Referring to fig. 1 to 3, an embodiment of the present invention includes:
the utility model provides a railway rail profile chi, this kind of railway rail profile chi includes telescopic link 1, support wheel 2, profile chi mount pad 3, profile chi body 4 and cushion 5, support wheel 2 is installed to 1 afterbody of telescopic link, 1 flexible head of telescopic link is fixed with profile chi mount pad 3, profile chi mount pad 3 stretches out the end and is provided with vertical mounting plane 30, installs profile chi body 4 on mounting plane 30, both sides are provided with the rail profile who detects two kinds of specification rails about the profile chi body 4, and rail profile department mark is equipped with a scale mark chi dual-purpose, profile chi mount pad 3 stretches out the end rear side and clamps and is used for the cushion 5 that supports.
The profile rule body 4 is made of 304 stainless steel.
The supporting wheels 2 are made of nylon materials, are light and convenient, and do not damage steel rails in the rolling detection process.
When the railway steel rail profile ruler works, after a grinding machine finishes grinding, the telescopic rod 1 is held by hand, the support wheel 2 and the cushion block 5 are erected on two steel rails, the steel rail profile of the profile ruler body 4 is clamped on the steel rails, when grinding is complete, each scale mark corresponds to the steel rail profile, if grinding is not in place, a gap exists between the profile ruler body 4 and the steel rails, the position which is not ground is found through the scale marks, then grinding is carried out, and if different steel rails are detected, the profile ruler body 4 can be rotated by 180 degrees, and the steel rail profile matched with the profile ruler can be selected.
The railway rail profile ruler provided by the utility model has the advantages of simple structure, ingenious design, convenience in operation, multiple purposes, capability of being compatible with two types of rails and cost saving.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
