Abstract
The utility model belongs to an instrument for measurement of high-speed railway slab, and particularly relates to a special crank arm measurement head for measurement of high-speed CRTS II railway slab, which solves the problem of alignment for template measurement of the prior high-speed CRTS II railway slab template. The special crank arm measurement head consists of a horizontal arm and a vertical arm vertical to the horizontal arm, wherein a plurality of slotted holes are formed on the horizontal arm; and the lower end of the vertical arm is designed to a bevel shape consistent with the slope angle of the nip of a rail-bearing groove. The special crank arm measurement head has the advantages that (1) the measurement head can extend downwards to the groove so as to keep contact with the point position to be measured, therefore, the problem of alignment is solved; (2) the measurement is easy to manufacture, and can achieve the accuracy requirement and the measurement accuracy; and (3) the measurement head has wide application due to the large-scale construction of the high-speed railway and the construction of a lot of railway slab factories. The special crank arm measurement head has high use value and wide prospect.
Description
Technical field
The utility model belongs to high-speed railway track plate to be measured and use utensil, is specifically related to a kind of high-speed railway CRTS II type track plate formwork measurement special use gauge head of cranking arm.
Background technology
At present, high-speed railway is built and is generally adopted CRTS II type prestressed concrete fragment-free track slab.This kind track plate manufacturing accuracy requires very high, adopts batch production production.Therefore also very high to producing the template accuracy requirement that the track plate uses.To laying the rail support groove template of rail, its linearity requires permissible variation only to be ± 0.3mm especially, and this has far surpassed the accuracy requirement of general civil engineering to template, must adopt precision measurement.And precision measurement has become a difficult problem to a problem.
Summary of the invention
The utility model is measured a problem in order to solve existing high-speed railway CRTS II type track plate formwork, provides a kind of high-speed railway CRTS II type track plate formwork to measure the special use gauge head of cranking arm.
The utility model adopts following technical scheme to realize:
A kind of high-speed railway CRTS II type track template is measured the special use gauge head of cranking arm, it is characterized in that it is made of mutually perpendicular horizontal arm and upright arm, have some slotted holes on the described horizontal arm, the lower end of upright arm is the bevel that meets the domatic angle of rail support groove jaw.
The utlity model has following beneficial effect:
1, the rail support groove template is reverse back-off when prefabricated, and rail support groove has partly formed to low groove.Therefore the general measure instrument is difficult to touch to point.The utility model can go deep into groove downwards, touches the some position that will measure, measures putting this difficult problem thereby solved.
2, the utility model is easy to processing, can reach accuracy requirement, satisfies the measuring accuracy needs.
3, the construction of high-speed railway is carried out just on a large scale, and a lot of track plate fields are just newly-built, and a large amount of track plate formworks needs to measure.Therefore, development of the present utility model has great practical value and promotion prospect.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the side view of Fig. 1
Among the figure: 1-horizontal arm, 2-upright arm, 3-slotted hole.
Embodiment
In conjunction with the accompanying drawings embodiment of the present utility model is described further.
One, structure of the present utility model
As shown in Figure 1 and Figure 2, high-speed railway CRTS II type track plate formwork is measured orthogonal two arms that the special-purpose gauge head of cranking arm is designed to the plate shape of steel.Horizontal arm 1 is provided with slotted hole 3, so that be fixed on the prism measuring table with screw.Upright arm 2 highly adheres to specification highly, and the oblique angle that meets the domatic angle of rail support groove jaw is made in the bottom, and the tip, oblique angle is used to contact the template surface conduct to a contact.Two of the utility model are formed a cover.
Two, use of the present utility model
1, horizontal arm of the present utility model is fixed on the prism measuring table with screw, and the horizontal arm extension elongation is regulated consistent.
2, regulating prism measuring table height makes tip, upright arm oblique angle adhere to specification with template contact point height.
3, will install the crank arm prism measuring table of gauge head of special use and be placed on one by one on the rail support groove template to be measured, use total station survey.
