Description

Technical Field

[0001] The utility model relates to the technical field of roadbed repair, in particular to a high-speed railway roadbed settlement repair operation device. Background Art

[0002] High-speed railway, referred to as HSR, refers to a railway system with high design standards and can be used for safe and high-speed travel of trains. Its concept is not limited to tracks, let alone trains. The roadbed is the foundation of the railway track. It bears the weight of the railway track and the dynamic load of locomotives and vehicles. At the same time, it is constantly attacked by water flow, wind and sand, rain and snow, severe cold, high temperature, etc. and various adverse geological conditions and human factors. Among them, the "high-speed railway roadbed settlement repair operation device" disclosed by the authorization announcement number "CN210368474U" has solved the problem of high-speed railway roadbed construction intensity and the need for repair. The existing railway needs to be blocked for construction, which restricts the passage of railway vehicles and has a long construction period. However, during use, bolts are horizontally inserted into the roadbed to connect the roadbed to the base plate. During the high-speed railway roadbed repair operation, the force it bears is supported only by bolts, which can easily cause damage to the high-speed railway base or bending of the bolts, affecting the subsequent high-speed railway roadbed repair work or the normal operation of the high-speed railway. In addition, the connecting holes are arranged horizontally, and when the high-speed railway passes by, vibration is generated, which can easily cause the bolts to loosen and fall off. Therefore, it is necessary to design a high-speed railway roadbed settlement repair operation device. Utility Model Content

[0003] The utility model aims to provide a high-speed railway subgrade settlement repair operation device to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-speed railway subgrade settlement repair operation device, comprising a high-speed railway subgrade, two connecting plates are arranged on the outside of the high-speed railway subgrade, both of the connecting plates are in close contact with the outer surface of the high-speed railway subgrade, a mounting plate is arranged on the outside of the connecting plate, a hydraulic rod is fixed on the upper surface of the mounting plate, the hydraulic rod is inclined, and one end of the hydraulic rod away from the mounting plate is fixed on the top of the connecting plate away from the surface of the high-speed railway subgrade.

[0005] When the high-speed railway subgrade is supported by the connecting plate for subsequent repair work, the inclined hydraulic rod is operated to drive the connecting plate to move toward the direction close to the high-speed railway subgrade, thereby increasing the contact friction between the connecting plate and the high-speed railway subgrade, improving the supporting effect of the connecting plate on the high-speed railway subgrade, and reducing the vibration generated by the high-speed railway subgrade when the high-speed railway passes.

[0006] Preferably, a connection hole is provided inside the high-speed railway foundation, a connection bolt is threadedly connected inside the connection plate, the connection bolt is located inside the connection hole, and the connection bolt and the connection hole are both inclined. The connection plate can be connected to the high-speed railway foundation by the connection bolt and the connection hole, and the connection bolt and the connection hole are inclined, which can further improve the stability between the high-speed railway foundation and the connection plate, and can prevent external moisture from accumulating inside the connection hole.

[0007] Preferably, a positioning cover is provided on the outer side of the end of the connecting bolt, a connecting block is fixedly provided on the outer side surface of the positioning cover, and a positioning spring is fixedly provided between the connecting block and the outer surface of the connecting plate. The elastic force of the positioning spring cooperates with the connecting block and the positioning cover to limit the position of the connecting bolt, thereby preventing the connecting bolt from loosening.

[0008] Preferably, the mounting plate is internally threaded with mounting bolts, and the mounting bolts are arranged obliquely. The arrangement of the mounting bolts can increase the stability of the mounting plate.

[0009] Preferably, a base plate is fixedly provided on the upper surface of the high-speed railway foundation, and a track is fixedly provided on the upper surface of the base plate. The track is installed through the base plate, which can increase the stability of the track.

[0010] Preferably, a fixing bolt is threadedly connected to the bottom of the track, and the lower end of the fixing bolt passes through the track and extends to the inside of the base plate. The track is installed by the fixing bolt, which is convenient for workers to disassemble and assemble the track.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The connecting plate is connected to the high-speed railway foundation through the connecting bolts and the connecting holes. The inclined hydraulic cylinder can move the mounting plate toward the direction close to the high-speed railway foundation. The position of the connecting bolts can be limited by the positioning spring, the connecting block and the positioning cover to prevent the vibration caused by the high-speed railway passing by, which may cause the connecting bolts to loosen and fall off. The connecting holes are inclined to prevent external moisture from accumulating inside the connecting holes, which may easily cause damage to the high-speed railway foundation.
