Detailed description of the invention
The one drawing enlarged footing anchor hole internal diameter provided this utility model below in conjunction with specific embodiment is surveyed
Measuring device is further described.
A kind of drawing enlarged footing anchor hole inside caliper, as shown in Figure 1, including being coaxially disposed from inside to outside
Pull bar 1, body 2, described pull bar 1 runs through described body 2 in the axial direction, and described pull bar 1 bottom sets
Being equipped with distraction plate 4, described distraction plate 4 card is vertical with pull bar 1, and described body 2 circumference is arranged with many
Measuring bar 3, the top of described measurement bar 3 is hinged and connected with the sidewall bottom of described body 2, described distraction plate
4 between symmetrical measurement bar 3.
Being provided with base plate 5 at the lower nozzle of described body 2, described base plate 5 center offers to be passed through for pull bar
Through hole, at the mouth of pipe of described body 2, be provided with top board 8, described top board 8 center offer for pull bar lead to
The through hole crossed.Pull bar 1 may pass through the through hole of base plate 5 and top board 8 and carries out straight line back and forth movement in the axial direction.
Further, the top of described pull bar 1 is provided with handle 9 to facilitate gripping.
Described base plate 5 is circumferentially with the flange 6 corresponding with measuring bar 3, described flange 6 offers for measuring
The linear gathering sill 7 that bar 3 passes through, as shown in Figure 2, gathering sill 7 plays position-limiting action to measuring bar 3.
Concrete, the width of described gathering sill 7 will measure bar 3 equal to the shank diameter of measurement bar 3, gathering sill 7
Clamping, makes measurement bar 3 can realize measuring bar 3 body of rod along gathering sill 7 and struts to peripheral direction or as inner circumferential
Direction is gathered.
Described distraction plate 4 generally circular in shape, fixing bottom distraction plate 4 center and pull bar 1.Concrete,
Being provided with two nuts bottom pull bar 1, distraction plate 4 plate body by two nut clampings thus is fixed with pull bar 1.
The 1/5-1/8 of a length of distraction plate 4 diameter of described gathering sill 7, a length of support of the body of rod of described measurement bar 3
Open plate 4 diameter 2-3 times.
Described measurement bar 3 number is two, and the lower end of described measurement bar 3 is provided with circular measurement 10.For
Convenience reads measures the numerical value obtained, and body of rod surface configuration at described pull bar 1 has straight with what measurement bar recorded
The scale groove that footpath is corresponding.
This utility model is achieved in that when measuring anchor hole internal diameter, according to the anchor hole diameter choosing of estimation
Select size and suitably measure bar 3 length and distraction plate 4 diameter, then go deep into measuring device, among anchor hole, working as survey
After gauge rod 3 arrives at the enlarged footing within anchor hole completely, stretching pull bar 1 makes pull bar 1 move upward in the axial direction,
Now, distraction plate 4 moves upward along with pull bar, and the measurement bar 3 contacted with distraction plate 3 border is at distraction plate 4
Effect under strut along gathering sill 7 to peripheral direction, when measure bar 3 lower end measurement 10 touch expansion
During major part hole wall, pull bar 1 motion stops, and is rotated a circle along the same depth location of anchor hole by measuring device, with
Determine that measurement 10, in maximum gauge position, after confirmation, can measure the diameter of enlarged footing.
