Multifunctional operating vehicle

Abstract

A multifunctional operating vehicle comprises a vehicle frame and a driving cab, wherein the driving cab is arranged on the vehicle frame. A working device is arranged at the front end of the vehicleframe and comprises two working arms. The middles of the working arms are fixedly connected, the rear ends of the two working arms are hinged to a fixing shaft at the front end of the vehicle frame, and a quick switching structure is arranged at the front ends of the two working arms, and comprises a first rod and a second rod. The first rod and the second rod are fixedly connected through fixingplates, a hinge pin is arranged in the second rod, and the two ends of the hinge pin stretch out of the fixing plates. A double-end oil cylinder is arranged in the middles of the two fixing plates, and an accessory is arranged at the front end of the quick switching structure. Rocker arms are arranged on the inner sides of the front ends of the two working arms, the top ends of the two rocker armsare fixedly connected through a third rod, the bottom ends of the two rocker arms are fixedly connected through a fourth rod, and the middles of the two rocker arms are fixedly connected through a fifth rod. The middle of the second rod is hinged to a connecting rod, and the tail end of the connecting rod is hinged to the third rod. The fourth rod is hinged to the telescopic end of a boom cylinder, and the fifth rod is hinged to the telescopic end of a rotating bucket oil cylinder. The double-end oil cylinder, the boom cylinder and the rotating bucket oil cylinder are connected to a working hydraulic system.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, in particular to a multifunctional work vehicle capable of loading and unloading, cleaning, manhole cover milling and other functions. Background technique [0002] Common loaders on the market can be used to shovel bulk materials such as soil and sand, and can also do light shoveling operations on ore and hard soil, and can also perform certain bulldozing and lifting operations by replacing different auxiliary working devices. However, the operation is difficult and time-consuming when replacing attachments, and generally requires the cooperation of multiple people, and the attachments have no independent flow supply system, so they can only perform simple operations. In addition, the chassis of the loader usually adopts an articulated chassis. There are disadvantages such as unstable center of gravity, poor comfort, uncompact structure, and large space occupation. Contents of th...
