Description

Technical Field

[0001] This utility model belongs to the field of contact wire technology, specifically relating to a simulation device for adjusting subway contact wire turnouts. Background Technology

[0002] Currently, there are generally two methods for adjusting overhead contact line switches. Method one involves using tools such as a plumb bob and measuring tape in conjunction with the adjustment work. The procedure is to hang the plumb bob on the overhead contact line and then use the measuring tape to re-measure the corresponding pull-out value on the rail. This needs to be repeated at each suspension point. Method two involves using an overhead contact line laser measuring instrument in conjunction with the adjustment work. The procedure is to re-measure at each suspension point.

[0003] The existing technical solutions, methods 1 and 2, serve the same main purpose: to measure data at each point on the overhead contact line. However, during construction, it is difficult to intuitively and quickly grasp the completeness of the overall parameters of a turnout section; therefore, measurements can only be taken at one point before moving on to the next.

[0004] Secondly, when using a plumb line, the line is suspended in the air and affected by the swaying of the wind, resulting in a large error value and extremely low construction efficiency.

[0005] Secondly, while the contact wire laser measuring instrument is powerful in measuring contact wire parameters, it can only measure parameters one by one. Although using multiple instruments in combination can achieve the goal of adjusting contact wire branches, the equipment investment and labor costs are high. Furthermore, in low-temperature environments, the battery power of the contact wire measuring instrument depletes rapidly, shortening its operating time. Utility Model Content

A handle is provided on the middle side of the measuring instrument base.

A rail clamping device is provided at the bottom left side of the measuring instrument base, and the rail clamping device has a tightness adjustment function.
