Auxiliary device for paving of Qinghai and Tibet Plateau railway

Abstract

The invention belongs to the technical field of rail traffic, particularly relates to an auxiliary device for paving of Qinghai and Tibet Plateau railway. In order to solve the problem that leveling can be performed for an area section with frozen earth often after shoveling needs to be performed firstly, and then filling is needed, and the operation is very tedious, the auxiliary device is characterized by comprising a frozen earth layer, a broken earth layer, a press roller and two square pipe crossbeams, wherein rectangular holes are respectively formed in positions, close to the front sections, on the opposite sides of the two square pipe crossbeams; two channel steel crossbeams of which the openings are opposite and which are mutual in parallel are welded between the two rectangular holes; the same rectangular sliding block is in slip connection between the two channel steel crossbeams; a driving tank which adopts a barrel-shaped structure is embedded in the middle of the rectangular sliding block. According to the auxiliary device disclosed by the invention, a drilling head can be enabled to slowly decline to be in contact with the surface of the frozen earth layer, and whenthe sharp end of the drilling head encounters a hard substance, the whole auxiliary device has a space for buffering upwards, so that a motor shaft is protected; a buffer spring is arranged, so that vibration of a driving motor can be converted into rhythmical downward impact force of the drilling head, so that the frozen earth layer is slowly broken.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to an auxiliary device for railway laying on the Qinghai-Tibet Plateau. Background technique [0002] The construction of the Qinghai-Tibet Railway has always been a difficult problem due to its complex terrain and climate factors. On the other hand, lack of oxygen on the plateau also increases the difficulty of road construction. Secondly, the ecological environment on the plateau is very fragile. Once it is greatly changed, it will cause a series of chain reactions. Therefore, it is not easy to move too much during the road laying process. The destruction of the surface cannot be too frequent; [0003] There is a special roadbed on the Qinghai-Tibet Railway, that is, a certain thickness of flake stones is filled at the bottom of the earth embankment, and a soil layer is paved on the roadbed. The roadbed needs to be leveled before laying. It is very difficult to level...

AI Technical Summary

Problems solved by technology

The roadbed needs to be leveled before laying. It is very difficult to level the section with frozen soil. It is necessary to level and break the raised frozen soil first, and then slowly insert the heated flakes into the soil layer, which takes a lot of money. step
