Hole detection mechanism provided with push frame

Abstract

The invention discloses a hole detection mechanism provided with a push frame. The hole detection mechanism comprises a conical base body, a plurality of section rods and a plurality of standard snaprings with different inner and outer diameters and height dimensions; the conical base body comprises a disk and a conical counter weight body fixed onto the bottom end of the disk; two uniformly distributed guide rods are fixed on the upper end surface of the disk; the standard snap ring comprises an annular main body and a fixing block which is integrally formed with the annular main body and disposed along the radial direction of the annular main body; a through hole through which the section rod can conveniently pass is formed at the middle of the fixing block; and the standard snap ringsof which the inner diameters are sequentially increased are nested to one another so as form a hole detection main body. According to the hole detection mechanism of the present invention, the standard snap rings of which the inner diameters are sequentially increased are nested to one another so as form the hole detection main body; the plurality of standard snap rings with different inner and outer diameters are additionally adopted, and therefore, the size of a certain position of an inner bundle pipeline can be calculated, and the detection of the apertures of different inner bundle pipelines can be facilitated; and a condition that an inner bundle pipeline is deformed when standard snap rings are additionally adopted and arranged in the inner bundle pipeline can be avoided.

Description

technical field [0001] The invention relates to the field of engineering construction equipment, in particular to a hole inspection mechanism provided with a push frame. Background technique [0002] There are many bundled pipes in the prefabricated box girder body. After the preparation of the prefabricated box girder body, it is necessary to measure the diameter of the bundled pipes in the prefabricated box girder. The size of the existing hole inspection mechanism with a push frame is single and fixed. To detect multiple pipes with different apertures, it is necessary to replace a different hole inspection mechanism with a push frame, which is time-consuming and laborious. The precise hole inspection mechanism is likely to cause deformation of the prefabricated box girder internal bundle pipe, and the position and amount of deformation cannot be determined, which brings great inconvenience to the later on-site installation and prolongs the construction period of the on-si...
