Description
Technical Field
The invention belongs to the field of engineering quality detection, and particularly relates to a civil air defense ventilation pipe inner diameter measuring device.
Background
According to the test and quality detection standard of civil air defense engineering protection equipment, the pipe diameter of the civil air defense ventilation pipe is an important index required by civil air defense, the detection of the outer diameter can be conveniently carried out by using the bow-shaped percentile ruler, but the detection of the inner diameter is difficult due to the long pipeline, and the pipe can only detect the inner diameter of the pipe orifice generally.
Disclosure of Invention
The invention provides a device for quickly measuring the diameter of an air pipe, which aims to solve the problem that the inner diameter of the middle section part of a civil air defense ventilation pipe is difficult to detect.
The invention relates to a device for rapidly measuring the diameter of an air pipe, which comprises: dolly, the vertical horizontal installation rotating head on the dolly of walking in the tuber pipe, radial symmetry install on the rotating head and measure the direction towards two laser range finder of pipe wall, the push rod of being connected with the rotating head, the push rod can promote the dolly and move ahead, and can drive the rotating head rotatory when the push rod rotates, and the digital display table in addition, the digital display table is laid in the tuber pipe outside, and the digital display table is connected with two laser range finder wires for show laser range finder's measured value.
The trolley is pushed into the air pipe through the push rod, the push rod is rotated, the two laser distance measuring instruments which are radially and symmetrically arranged on the rotating head measure the distance to the pipe wall, the measured value is displayed on a digital display meter outside the pipe, the sum of the measured distances of the two laser distance measuring instruments and the distance between the two laser distance measuring instruments obtain the inner diameter size of the air pipe, a plurality of inner diameter sizes in the circumferential direction of the air pipe can be measured through rotating the rotating head, after one section is measured, the trolley is pushed forward through the push rod, the inner diameter of the next section of the air pipe is measured, and the inner.
The invention comprises a trolley running in an air pipe, a rotating head longitudinally and horizontally arranged on the trolley, two laser distance measuring instruments which are radially and symmetrically arranged on the rotating head and are provided with measuring heads back to each other, and a push rod connected with the rotating head.
