Description

Technical Field

[0001] The utility model relates to the technical field of railway laying, in particular to a positioning auxiliary device for plateau railway laying. Background Art

[0002] During the laying and installation of the railway, the tracks on both sides need to be positioned, and then the tracks are fastened with accessories. The current positioning device is set between the two tracks, but because there are many stones at the bottom of the track, the road between the tracks on both sides is bumpy, making it difficult to move the positioning device, affecting the efficiency of track laying.

[0003] A Chinese patent with publication number CN214362613U was searched and disclosed, which is an auxiliary positioning device for preventing lateral displacement of tracks. The device can be moved on the track by means of rollers, so as to improve the moving efficiency of the device when laying tracks. This solves the problem that the current positioning device is arranged between two tracks, but due to the large number of stones arranged at the bottom of the track, the road between the tracks on both sides is bumpy, making it difficult for the positioning device to move, thus affecting the efficiency of track laying.

[0004] Based on the above search and combined with the prior art, it is found that the above patent has certain defects. The support plate is controlled by a driving motor to close or separate periodically, and the lifting and lowering of the roller is controlled by an electric push rod to support the movement. The storage of the roller cannot be synchronously controlled when controlling the positioning of the support plate. The roller support is automatically ejected when the support plate is loosened and released. The maintenance cost is higher through control of multiple electric push rods, and the motion control is not flexible enough, which reduces the utilization efficiency of the railway laying positioning auxiliary device.

[0008] Preferably, both side outer walls of the bidirectional screw are connected to support plates through threads, both side outer walls of the top of the bottom plate are provided with rectangular holes, the support plates are slidably connected to both side inner walls of the rectangular holes, and both side outer walls of the rectangular holes are fixedly connected to fixed blocks.

The pressing plate and the force plate which are arranged in a right-angle trapezoidal shape both have inclined surfaces. During the pressing process, the force plate drives the mounting frame to descend, the telescopic rod and the spring are stretched, and the roller support at the bottom of the mounting frame makes the rotating wheel suspended in the air for easy movement. When positioning is required, a driving motor controls the transmission rod to rotate in the opposite direction, the support plate is closed for clamping and fixing, the pressing plate is reset, and the force plate and the mounting frame are reset under the action of the spring on the outer wall of the telescopic rod. The lifting and lowering of the roller is realized through the linkage structure, and the roller is stored while the support plate is clamped and positioned.
