Description

Sleeper laying structure for railway tunnel

Technical Field

The utility model relates to a technical field is laid to the sleeper, specifically is a sleeper laying structure for railway tunnel.

Background

Railway tunnels are buildings constructed underground or underwater and provided with railways for locomotive vehicles to pass through, and are classified into three major categories according to their locations, namely mountain tunnels for traversing mountains or hills to shorten the distance and avoid large slopes, underwater tunnels for traversing rivers or straits to pass through rivers or undersea, and urban tunnels for traversing cities and underground to meet the needs of railways to pass through large cities, and among the three categories, mountain tunnels are most constructed.

And in building mountain tunnel in-process, the machine is laid evenly with the sleeper to the many needs sleeper, lay the back, evenly settle the limiting plate in sleeper both sides, be used for placing and carry out roll adjustment in-process lateral shifting between the sleeper, then carry out the sleeper range finding, adopt laser range finder range finding at present more, need put the reference object at sleeper face fixed position in the range finding process, then reuse laser is beaten apart from, and suitable spacing is adjusted and is not conform to the sleeper of standard, the weak point of existence has: whether the space between the sleepers meets the standard or not is detected by adopting a laser distance measuring mode, only one sleeper can be detected at a time, the position needs to be temporarily determined on the sleeper surface, and then a reference object is placed, so that the detection is not convenient enough.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a sleeper laying structure for railway tunnel to propose once only can detect the problem whether a sleeper interval accords with the standard in solving above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a structure is laid to sleeper for railway tunnel, includes the backup pad, the backup pad facial make-up is equipped with a plurality of sliding sleeves, the card frame has all been installed to the bottom of sliding sleeve, the one end of sliding sleeve all is equipped with the screw hole, screw hole female connection screw rod, the one end of screw rod has been installed and has been supported the compression leg, it is equipped with the damping ring to support the compression leg facial make-up, the handle has all been installed to the both sides of backup pad.

Preferably, the supporting plate is of a square plate structure, and the sliding sleeve is of a square sleeve structure.
