Abstract
The invention discloses a device for detecting an appearance size of an expansion joint. The device comprises a detecting platform, a detecting magnetic base, a first measuring tool, a second measuring tool and a positioning bar, wherein the detecting platform is of a carbon steel plate; area and thickness of the detecting platform can meet requirements on the area and weight for bearing the expansion joint; the first measuring tool is fixed on the detecting platform through the magnetic base; the first measuring tool is fixed with the magnetic base and is perpendicular to the detecting platform; the measuring tool is of a vernier caliper; the second measuring tool is transversely arranged in 90 degrees with the vertical first measuring tool; and the second measuring tool moves up and down along the first measuring tool. A beginning point of a 0-scale of the second measuring tool is arranged at an outer vertical face of the first measuring tool. The device is manufactured by modifying a detecting tooling according to a theory of the vernier caliper, then a measurement result is more accurate; the device is convenient to use and high in efficiency when multiple parameters are measured synchronously; the device is particularly suitable for measuring the appearance size of the expansion joint; and a defect of the prior art is solved.
Description
Technical field
The present invention relates to expansion joint apparent size pick-up unit, belong to the machine-building field of measuring technique.
Background technology
The extra-stress that expansion joint causes because of temperature difference and mechanical vibration for compensation, and be arranged on a kind of flexible structure on shell of tank or the pipeline.Because it is as a kind of elastic compensating element that can freely stretch, advantages such as reliable operation, functional, compact conformation have been widely used in fields such as chemical industry, metallurgy, nuclear energy.And this has also just had higher requirement to the apparent sizes such as the wave height pitch of waves of expansion joint.If these sizes have deviation or deviation bigger, the usability of expansion joint is had very big influence.Thereby the result of use and the life-span of equipment have been influenced.
The resultant error that former detection method is measured is bigger, and will detect step by step, can't measure wave height, right alignment, overall height together.
Summary of the invention
The objective of the invention is, propose a kind of expansion joint apparent size pick-up unit, measurement result is wanted accurately.Convenient during use, efficient is higher.Especially design an easy dimensional measurement frock, be used to measure the expansion joint apparent size, solve two problems that above-mentioned prior art exists.
Technical scheme of the present invention is: expansion joint apparent size pick-up unit
,Comprise detection platform, detect magnet base, first and second measurer and positioning strip; Detection platform is that carbon steel is dull and stereotyped; Its area and thickness satisfy the area and the weight requirement of bearing expansion joint; Fixing first measurer of magnet base is on detection platform; First measurer and magnet base are fixed, and perpendicular to detection platform, said measurer is a vernier caliper; Second measurer and the first vertical measurer become again 90 ° horizontal, second measurer is up and down along first measurer.0 scale starting point of second measurer is positioned at the outer facade of first measurer.
Be provided with that positioning strip 5 is installed on second measurer and parallel with first measurer, vertical with second measurer.The wave height that is used for the subsidiary expansion joint.0 scale mark begins from the detection platform face.(first measurer not only can be measured the height of expansion joint but also can be used as the right alignment that a ruler is measured expansion joint).Positioning strip 5 is enclosed within on the bar of second measurer through a sliding sleeve.
The invention has the beneficial effects as follows: a kind of expansion joint apparent size pick-up unit that the present invention proposes, it is to change a social system according to vernier caliper principle that the present invention detects frock, makes measurement result accurate.Convenient during use, multi parameter simultaneous measuring and efficient is high.The present invention is specially adapted to measure the expansion joint apparent size, has solved the deficiency of prior art.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in the figure, detection platform 1, expansion joint 2, magnet base 3, first measurer 4, second measurer 6, positioning strip 5,0 scale mark 7.
First: detection platform is the core of this device.At first be that the selection of platform: carbon steel sheet 4m * 4m is square, surperficial Vehicle Processing is seen flat, thickness 50mm.Also can use the dull and stereotyped platform of carbon steel sheet of different size and thickness.
Second portion: magnet base.Be used for fixing measurer on detection platform.At screw thread of the side of magnet base processing, with first measurer and magnet base vertical fixing (vertical) with flat board.Become a try square shape.0 scale mark 7 begins from the detection platform face.Said measurer is a vernier caliper.
Third part: measurer and positioning strip.Measurer is wanted accurately, and metering regularly.Complete metering report is arranged, and by the metrological personnel keeping.According to the size of the expansion joint of measuring, replaceable measurer range.First measurer is fixed (first measurer not only can be measured the height of expansion joint but also can be used as the right alignment that a ruler is measured expansion joint) second measurer and is become 90 ° again with the first vertical measurer with magnet base; Second measurer is enclosed within on the bar of first measurer through a sliding sleeve; Sliding sleeve is provided with screw and first measurer and fixes or unclamp, and makes second measurer up and down along first measurer.0 scale starting point of second measurer is positioned at the outer facade of first measurer.And positioning strip is parallel with first measurer, and is vertical with second measurer.The wave height that is used for the subsidiary expansion joint.Positioning strip 5 is enclosed within the structure said structure roughly the same on the bar of second measurer through sliding sleeve.
Method of application of the present invention:
1. the expansion joint that will detect is placed on the detection platform.
2. installation magnet base, measurer length according to the expansion joint height that will detect regulate, guarantee that range is enough.
3. second measurer 6 and positioning strip are installed.
4. promote magnet base with first measurer 4 and the snap of expansion joint inwall.Second measurer 6 moves to the expansion joint port, sees that first measurer 4 and expansion joint inside surface have or not the gap, reads the reading of second measurer 6, and these data are that two mouthfuls right alignment is poor up and down for expansion joint.
5. these data of data of reading second measurer are the height of expansion joint.
6. the slip positioning strip makes it to be close to the expansion joint crest, reads the size of second measurer, and these data are the wave height of expansion joint.
