Title:
EXPANDABLE MULTI-FUNCTION WORKING VEHICLE HAVING BIDIRECTIONAL OPERATION AND TRANSVERSAL EVACUATION FUNCTION AND USE METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/100890
Kind Code:
A1
Abstract:
An expandable multi-function working vehicle having a bidirectional operation and transversal evacuation function comprises a fixed lifting mechanism (2) and a traverse lifting mechanism (4). The working vehicle is formed by a front vehicle body and a rear vehicle body. The front vehicle body and the rear vehicle body are connected by an expandable mechanism used to realize contraction and expansion between the front vehicle body and the rear vehicle body. The working vehicle further comprises a hoisting system (6) for hoisting and moving a working device (7). A rail engagement device is provided at the bottom of the working vehicle. The working vehicle has an expandable structure, such that a vehicle body (1) can expand in a lengthwise direction thereof, thereby facilitating operation, driving, and transshipment. The working vehicle stays clear of a railway in a transversal direction thereof, ensuring convenient operation of the working vehicle in a long segment of the railway. The invention achieves greater productivity and a wider range of applications. A reasonable combination of vehicle lifting and rail lifting reduces the work load of railway personnel and improves construction efficiency. A variety of working devices can be mounted on the working vehicle. The vehicle is well suited for a variety of working conditions and is highly versatile. The invention further provides a use method for the expandable multi-function working vehicle having a bidirectional operation and transversal evacuation function.
