Problems solved by technology

[0002] For the measurement of the inner diameter of deep holes, the commonly used method is to manually observe the comparison method through a ruler or use the inner diameter caliper measurement method, but it is impossible to quickly and accurately measure the inner diameter of the deep anchor hole, which greatly reduces the accuracy of the test results.
Moreover, the expansion head of the anchor hole expands unevenly, which makes it more difficult to measure the diameter of the deep anchor hole.

Embodiment Construction

[0016] A tension-type enlarged head anchor hole inner diameter measurer provided by the present invention will be further described below in conjunction with specific embodiments.

[0017] A tension-type enlarged head anchor hole inner diameter measuring device, as attached figure 1 As shown, it includes a pull rod 1 and a pipe body 2 coaxially arranged from the inside to the outside. The pull rod 1 runs through the pipe body 2 along the axial direction. 4. The disk surface is perpendicular to the pull rod 1. The pipe body 2 is circumferentially symmetrically provided with a plurality of measuring rods 3. The top ends of the measuring rods 3 are hingedly connected to the bottom of the side wall of the pipe body 2. The expansion plate 4 is Between the symmetrical measuring rods 3.

[0018] A bottom plate 5 is provided at the lower nozzle of the pipe body 2, and a through hole for the passage of the pull rod is provided at the center of the bottom plate 5. A top plate 8 is arra...

Abstract

The invention provides a stretching expanded head anchor hole inner diameter measuring device, which comprises a pulling rod (1) and a pipe body (2) arranged coaxially from inside to outside, wherein the pulling rod (1) passes through the pipe body (2) along an axis direction; the bottom end of the pulling rod (1) is provided with an opening plate (4); the disc of the opening plate (4) is vertical with the pulling rod (1); the circumference of the pipe body (2) is symmetrically provided with multiple measuring rods (3); the top end of each measuring rod (3) is hinged with the bottom of the side wall of the pipe body (2); and the opening plate (4) is located between symmetrical measuring rods (3). As for a non-uniform expanding anchor hole expanded head, the device can quickly and precisely measure the inner diameter of the anchor hole expanded head, the measuring time can be greatly saved, and the measuring efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of anchor hole inner diameter measurement, and in particular relates to a tension-type enlarged head anchor hole inner diameter measurer. Background technique [0002] For the measurement of the inner diameter of deep holes, the commonly used methods are manual observation and comparison with rulers or measurement with inner diameter calipers, but the inner diameter of deep anchor holes cannot be quickly and accurately measured, which greatly reduces the accuracy of test results. Moreover, the expansion head of the anchor hole expands unevenly, which makes it more difficult to measure the diameter of the deep anchor hole. Contents of the invention [0003] In view of this, the present invention provides a tension-type expansion head anchor hole inner diameter measuring instrument, which can quickly and accurately measure the inner diameter of an unevenly expanded anchor hole expansion head, can greatly sav...
