The object of the present invention is achieved like this：A kind of bridge machinery field hinge seam displacement measuring device, exists as top pressure
Contact on the hinge seam left beam body bottom surface in side is fixed on measurement bar upper end, and measurement bar is placed in the sliding slot of fixed ruler with moving freely
Interior, compression spring is arranged between measurement bar lower end and fixed ruler, and measurement bar lower end is provided with pointer；Round bar is by cross bar and erects
Bar connection composition；Cross bar left end is connected firmly on fixed ruler, and cross bar right end is connected with montant lower end, and length adjuster is connected to
On cross bar, montant upper end is sequentially connected with steering adjuster and the base as top pressure on the right beam body bottom surface of hinge seam opposite side.
The contact is a steel plate, and the base is the steel base of top surface smooth-going.
The round bar is steel round bar.
Length adjuster and the steering adjuster structure is：Have axial half in cylinder or the steel body of square column type
Hole, is fixed with a spring in half bore.
During measurement, first base is placed in the beam body of hinge seam side, then by steering adjuster and length adjuster, will touched
Head is accurately placed in the surface of hinge seam opposite side beam body, and the change of pointer will be driven when hinge seam is subjected to displacement, is passed through
The reading of reading pointer on the scale come determine hinge seam displacement.
Beneficial effects of the present invention：The present invention provides a kind of measuring device for hinge seam displacement measurement.The apparatus structure is simple,
It is easily operated, measurement error is small, has higher accuracy, can fast and accurately measure hinge seam displacement.Meanwhile the dress
It is simple to put principle, cost is cheap.
Brief description of the drawings
Fig. 1 is measuring device structural map of the present invention.
Embodiment
Reference numeral is in figure：1-beam body；2-base；3-steering adjuster；4-round bar；5-length adjuster；
6-measurement bar；7-contact；8-fixed ruler；9-pointer；10-spring；11-hinge seam.
Technical scheme is described in further detail below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to
It is as described below.
The present embodiment a kind of bridge machinery field hinge seam displacement measuring device, by by base, round bar, length adjuster,
Steering adjuster, fixed ruler with a scale, contact, measurement bar and pointer composition.
A kind of bridge machinery field hinge seam displacement measuring device, as top pressure on the hinge seam left beam body 1a bottom surfaces in 11 sides
Contact 7 is fixed on 6 upper end of measurement bar, and measurement bar 6 is placed in the sliding slot of fixed ruler 8 with moving freely, and compression spring 10 is arranged on
Between 6 lower end of measurement bar and fixed ruler, and 6 lower end of measurement bar is provided with pointer 9；Round bar 4 is connected by cross bar with montant to be formed；It is horizontal
Bar left end is connected firmly on fixed ruler 8, and cross bar right end is connected with montant lower end, and length adjuster 5 is connected on cross bar, montant
Upper end is sequentially connected with steering adjuster 3 and the base 2 as top pressure on right 11 bottom surface of beam body of hinge 11 opposite sides of seam.
The base of the measuring device has larger rigidity, is unlikely to deform, and the material of base can be steel, the shape of pedestal
Shape can be circle, rectangle etc., but have to ensure the smooth-going of pedestal top surface, not bend, and when measurement will ensure that base stitches one with hinge
Curb girder body tightly contacts, and driven therewith.
Contact is a small plain plate, its top planes is tightly contacted with hinge seam opposite side beam body, and driven therewith.
Round bar has larger rigidity, not flexible, is unlikely to deform, and to ensure hanging down for round bar and base end face at the same time
Directly.
Length adjuster is located on cross bar, can elongate the length for shortening cross bar；Steering adjuster is located at base and round bar
Junction；Pass through length adjuster and steering adjuster, it is possible to achieve long range, 360 ° of measurements without dead angle.
Fixed ruler is connected with round bar, is equipped with sliding slot in quarter fixed ruler, measurement bar can move freely in sliding slot.Measurement
Bar has greater stiffness, is not easy flexural deformation, and the upper end of measurement bar is connected with contact, and lower end is connected with pointer.
Length adjuster structure is：Steel body（Such as cylinder, square column type）On have an axial half bore, it is fixed in half bore
There is a spring.Its connection mode is：The right end that left section of cross bar is actively stretched into the half bore of steel body and is connected with spring, cross bar
Right section of left end is connected firmly with steel body.
The structure of steering adjuster is identical with the structure of length adjuster, its connection mode is：Montant hypomere it is upper
End is actively stretched into the half bore of steel body and is connected with spring, and the right end of right section of lower end and the cross bar of montant hypomere is connected, and erects
The lower end of bar epimere is connected firmly with steel body, and the upper end of montant epimere is fixed on base.
The application method of this measurement beam bridge hinge seam gearshift, comprises the following steps：
（1）Pointer is calibrated：Total indicator reading is calibrated in 0 graduation mark position.It should be guaranteed that the contact of measurement bar side when reading is 0
Same level height is in base end face（The requirement can be added to inside claim）.
（2）The fixation of base：Right beam body surface contaminants, dust and soft part are removed, beam body surface is polished smooth.When
When hinge seam displacement will measure for a long time, base can be fixed in beam body by its subsidiary bolt hole；If simply measure certain
During the hinge seam displacement of one moment, base is pressed in beam body by base by human hand.
（3）Contact positions：After the completion of ensuring that base is fixed, by length adjuster and steering adjuster by the accurate nothing of contact
It is adjusted to need the left beam body target location measured by mistake, should be guaranteed that contact and beam body close contact or fixation at this time.
（4）Reading：Reading pointer change after stabilization reading, accuracy of reading according to measurement error it needs to be determined that, gained
Reading is the displacement for cutting with scissors seam both sides beam body.Complete whole measurement process.
Need a bit illustrated：The device and application method of above-mentioned simply measurement hinge seam both sides beam body relative shift.When
When needing the absolute displacement of a certain survey beam body of measurement hinge seam, which only needs to add a steering to adjust again in the position of cross bar
Device, is placed in fixed point during measurement by base, other constant.
