Engineering vehicle

Abstract

The invention discloses an engineering vehicle. The engineering vehicle comprises a chassis, a bearing platform arranged on the chassis and an aboard and machine tool platform. The aboard and machinetool platform is arranged on the bearing platform in an interval mode, and the machine tool platform is used for placing at least two machine tools so that an aboard operating arm can replace the machine tools. The engineering vehicle has a working state and a machine tool replacement state. The machine tool platform is rotatably arranged relative to the bearing platform so that the operating armcan correspond to the position of a machine tool to be replaced in the at least two machine tools to be replaced in the machine tool replacement state. The engineering vehicle is provided with a machine tool platform which is arranged on the bearing platform and specially used for placing the machine tools, the machine tool platform can be rotated relative to the bearing platform, when the machinetools need to be replaced, the machine tool platform can be controlled to rotate to enable the operating arm to correspond to the positions of the machine tools to be replaced on the machine tool platform so that the operating arm can be connected with the machine tools to be replaced, the replacement time of the machine tools is reduced, and the operation efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an engineering vehicle. Background technique [0002] With the development of excavator technology and the continuous innovation of equipment, the operating arm of the excavator can be equipped with various equipment such as breaker, hydraulic shear, stone grabber, compactor, rock saw, etc. to meet different operating needs. In general, the working arm will use this tool to work for a long time after changing one tool without frequent replacement of other tools. However, in some special cases, such as emergency rescue, the operating arm needs to frequently replace the working tools in a short period of time according to different working conditions, which requires such engineering vehicles to carry multiple tools. [0003] Most of the various machinery and tools of construction vehicles are fixed on the frame by ropes and slings. When the machinery needs to be repl...

AI Technical Summary

Problems solved by technology

However, in some special cases, such as emergency rescue, etc., the operating arm needs to frequently replace the operating tools in a short period of time according to different working conditions, which requires this type of engineering vehicle to carry a variety of tools

[0003] Most of the various machines and tools of construction vehicles are fixed on the frame by ropes, slings, etc. When the machines need to be replaced, they need to be disassembled and installed manually, which seriously affects the operation efficiency and takes up too much rescue time

However, various tools of some engineering vehicles need to be equipped with special auxiliary vehicles for transportation, which is costly and reduces the application range of engineering vehicles.
