Simple track gauge pull rod device for tunnel construction

Technical Field

The utility model belongs to the technical field of the tunnel construction, specific theory relates to a tunnel construction is with simple and easy track gauge pull rod device.

Background

In tunnel engineering construction such as water conservancy and hydropower, municipal administration, highway, railway, adopt the mode of rail transportation, lay the rail through installing interim sleeper in shaping tunnel bottom, transport personnel, equipment and goods and materials through diesel locomotive or storage battery locomotive to ensure that construction work normally goes on. However, in the actual construction process on site, due to weak geology and long-time operation of a locomotive, the bolt of a sleeper rail pressing block is loosened, the requirement for the precision of the rail spacing cannot be met, and the rail spacing is too large, so that derailment is easy to occur in the operation process of the locomotive and safety accidents occur. The prior general method for keeping the track gauge of the track comprises two methods, one is to open a hole at the waist position of the original track and transversely connect two steel rails by adopting a track gauge pull rod, and the method destroys the original structure of the track, causes irreparable damage to the track and is not beneficial to the recycling of the track; the other method is to transversely connect two steel rails at the bottom of the rail through the gauge pull rod, the method needs manufacturers to customize a gauge pull rod device, the production period is long, the use cost is high, and the gauge pull rod is more applied to building running lines of high-speed rails, subways and the like of a general traffic train. Therefore, in order to ensure the operation safety of the locomotive, reduce the occurrence of the derailment of the locomotive, and simultaneously, in order to reduce the construction cost and improve the construction and transportation efficiency, a self-made simple track gauge pull rod device needs to be designed urgently.
