Description

Technical Field

[0001] The utility model belongs to the technical field of railway construction measurement equipment, and in particular relates to a contact network support foundation stud measurement device. Background Art

[0002] my country has a vast territory, and the length of high-speed railways and passenger-dedicated railways far exceeds that of other countries, making construction and maintenance the most difficult. The overhead contact network project is an important part of the electrified railway. The overhead contact network foundation is generally designed every 50 meters, and there are many foundations along the line. For example, the main line of the Guinan High-speed Railway in Guangxi is 305.66 km long, with nearly 7,000 overhead contact network foundations. The overhead contact network foundation is generally arranged in double lines with a spacing of about 50 meters, and a single foundation has an average of 8 to 10 anchor bolts. The overhead contact network foundation is usually reserved by the construction unit before the station. The foundation bolts are generally prone to problems such as insufficient exposed length, excessive bolt spacing, bolt tilt, bolt corrosion, bolt bending or fracture, and bolt thread damage. The parameters and quality that do not meet the standards will affect the pillar assembly construction. In the early stage of construction, the interface inspection process needs to be checked, measured, and recorded one by one to form an interface problem record table. Generally, there are 2 surveyors, and it takes an average of 7 minutes to measure each foundation. The workload of manual inspection, measurement and record keeping is extremely large, and it is difficult to simultaneously save image data. During the establishment of the inspection ledger, data is entered repeatedly, which is prone to human errors. Failure to organize data in a timely manner leads to multiple visits to the construction site for re-measurement, wasting a lot of time.

[0003] Therefore, the workload of interface inspection in the early stage of construction is large, the measurement work is cumbersome, the amount of data recording is large, and the outdoor work intensity is high. In order to obtain a set of foundation bolt data, interface inspection measurement personnel often need to measure and record repeatedly. The measurement and recording work sometimes has large human errors and is inefficient. Utility Model Content
