Description

Technical Field

[0002] At present, the operating mileage of urban rail in China has reached more than 7,500 kilometers. According to the Urban Rail Transit Development Plan for 2035, 86 cities in my country will develop rail transit, and the planned line mileage will reach more than 30,000 kilometers. With the continuous development of urban rail transit, the workload of urban rail maintenance has become increasingly heavy, and the operating lines of urban rails are facing prominent problems such as equipment aging, failure, and safety hazards. Casing failure is one of the common problems, especially the casing of the rail engineering fastener system, which can affect the comfort of the ride at the least and endanger the driving safety at the worst. At present, there is no positioning device specifically for the failed casing in the process of drilling and coring during the anchoring construction on the market. The existing casing anchoring construction drilling positioning depends entirely on experience and trial drilling. The hole accuracy and verticality pass rate depend on the technical level and experience of the operators.

[0003] The problems existing in the existing technology are as follows: (1) The positioning of anchor change depends entirely on experience and has low accuracy; (2) When drilling holes for anchor change construction, a test drill is first performed, and then the test drill position is checked to see if it is qualified. If it is qualified, drilling is continued. If it is unqualified, the drill position needs to be readjusted and then drilling is performed, resulting in low efficiency of anchor change; (3) During the test drilling for anchor change construction, there is a safety hazard of drill bit shaking, or even the anchor change machine losing control and injuring people; In summary, the existing anchor change construction positioning technology has the disadvantages of difficulty in ensuring hole accuracy and verticality, low construction efficiency, and high safety risks.
