Dual-purpose excavator railway wheel system lifting and driving device for highways and railways

Abstract

The invention relates to a dual-purpose excavator railway wheel system lifting and driving device for highways and railways. The dual-purpose excavator railway wheel system lifting and driving device comprises a vehicle frame and a push shovel, wherein the front part of the vehicle frame is hinged with the push shovel, the back part of the push shovel is provided with a pair of driven wheels, a front hydraulic oil cylinder is hinged between the middle of the back part of the push shovel and the front end of the vehicle frame, the push shovel is driven through the hydraulic oil cylinder for lifting the driven wheels, the back part of the vehicle frame is hinged with a driving wheel support frame, a pair of driving wheels are arranged on the driving wheel support frame, in addition, a back hydraulic oil cylinder is hinged between the middle of the back part of the driving wheel support frame and the back end of the vehicle frame, the driving wheel support frame is driven through the hydraulic oil cylinder for lifting the driving wheels, and the driving wheels are driven through a hydraulic motor. A railway wheel system capable of realizing the driving lifting through a hydraulic system is hinged at the front and back parts of the existing crawler type excavator vehicle frame, so an ordinary crawler type excavator can operation along the railway, and the dual-purpose excavator railway wheel system lifting and driving device can be widely applied to operations such as railway line emergency repair, new line erection and cable construction at two sides of the railways.

Description

technical field [0001] The invention relates to a railway wheel system lifting and driving device for a road-rail dual-purpose excavator, which belongs to the technical field of railway engineering machinery. Background technique [0002] Ordinary excavators have crawler-type or tire-type running mechanisms, which can only be used for construction work on ordinary construction sites. They do not have the functions of running and working on railways, and cannot meet the operational needs of emergency repairs of railway lines, erection of new lines, and construction of cable trenches on both sides of railways. Contents of the invention [0003] The technical problem solved by the present invention is to design a railway wheel system lifting and driving device for a road-rail dual-purpose excavator. After adding this set of devices, the ordinary excavator can run along the railway, and can be widely used in railway line repair, new line erection, railway line construction, etc...

AI Technical Summary

Problems solved by technology

[0002] The running mechanism of ordinary excavators is crawler or tire type, which can only be used for construction work on ordinary construction sites. It does not have the function of running and working on railways, and cannot meet the operational needs of railway line repairs, new line erection, and cable trench construction on both sides of the railway.
