Abstract
Description
Technical Field
[0001] This utility model relates to the field of twist detection technology, specifically to a contact wire foundation twist detector. Background Technology
[0002] With the rapid development of modern rail transit, the overhead contact system, as a key facility for power transmission, is crucial for ensuring the normal operation of trains. The overhead contact system foundation, as the cornerstone supporting the entire system, directly affects the operational performance of the system. However, due to long-term exposure to environmental erosion, train vibration, and material aging, the foundation is prone to torsional deformation. If this deformation is not detected and repaired in time, it can lead to serious accidents such as tilting of overhead contact towers and conductor detachment, threatening train operation safety.
[0003] Traditional methods for inspecting overhead contact lines mainly rely on manual observation and simple measuring tools, which suffer from problems such as low efficiency, poor accuracy, and strong subjectivity, making it difficult to meet the requirements of modern rail transit for safety and efficiency.
[0004] Therefore, a contact wire foundation twist detection instrument is needed to improve the above-mentioned problems. Utility Model Content

[0008] As a preferred embodiment of this utility model, a set of hinge members is provided, and the adjustable upright can rotate relative to the hinge members.
[0009] As a preferred embodiment of this utility model, the connection structure includes a set of connecting blocks. Two connecting blocks are respectively distributed on the inner side of the two adjustable uprights. Each adjustable upright is provided with a fixing plate on its outer side. The fixing plates on both sides are connected into one piece by a connecting rod a, which passes through the connecting block.
[0010] As a preferred embodiment of this utility model, the lower support member includes a support plate, and a connecting rod b is provided through the support plate and the connecting block to connect the support plate.

[0025] The inspection holes 4 of the anchor bolt hole spacing inspection mold 1 are used to inspect the pre-embedded status of the anchor bolts. According to the limit value of the contact network foundation, the length of the limit measuring ruler 10 is adjusted. Under the condition that the limit requirements are met, the short crossbar 11 (the reference end of the rail) is set on the inner edge of the rail. The rail surface is used as the reference surface of the foundation. The height is adjusted according to the rail foundation height difference required by the design and the bubble condition of the level ruler on the measuring ruler. After the height is adjusted to the design value, the adjustable upright 3 is locked. Finally, the gap between the short crossbar and the inner edge of the rail is measured.
