Description

Technical Field

[0001] This utility model relates to the field of bridge installation technology, and in particular to a through-hole rate inspection device for trial assembly of steel bridges. Background Technology

[0002] A bridge generally refers to a structure erected over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. To adapt to the modern, rapidly developing transportation industry, the term "bridge" has also been extended to refer to structures erected to cross mountains, overcome adverse geological conditions, or meet other transportation needs, making travel more convenient. A bridge generally consists of a superstructure, substructure, supports, and ancillary structures. The superstructure, also known as the bridge span structure, is the main structure that crosses obstacles. The substructure includes abutments, piers, and foundations. Supports are force-transmitting devices installed at the support points between the bridge span structure and the piers or abutments. Ancillary structures refer to bridge approach slabs, tapered slopes, revetments, and diversion works, etc. During bridge trial assembly, it is necessary to check the perforation rate, which requires the use of a perforation rate checking device.

[0003] However, in practical applications, it is necessary to use a device to inspect the through holes, which will require inspection devices of different sizes. If it is inconvenient to replace the inspection parts during use, the parts will need to be replaced frequently in subsequent use, thus reducing the ease of use of the device. Utility Model Content
