All-terrain multi-functional pipe lifting machine based on excavator platform

Abstract

The invention discloses an all-terrain multi-functional pipe lifting machine based on an excavator platform, and belongs to the technical field of pipe lifting machines. The all-terrain multi-functional pipe lifting machine based on the excavator platform comprises a chassis component, a pipe lifting working device, a rotary table component and a revolving mechanism; the chassis component and the rotary table component are connected with the revolving mechanism, the front end of a connector is connected with a lifting arm and lifting system, the front end of the connector and the root of the lifting arm and lifting system are connected with a variable-amplitude oil cylinder, the two ends of a variable-rail oil cylinder are connected with a vehicle frame and a crawler belt longitudinal beam respectively, a crawler belt is mounted on the surface of the crawler belt longitudinal beam, and a dozer blade is fixedly mounted at the front end of the vehicle frame. According to the all-terrain multi-functional pipe lifting machine based on the excavator platform, switching between an excavating and a pipe lifting function can be achieved; corresponding crawler belts can be switched according to construction terrains; an execution mechanism is additionally arranged on a lower vehicle to achieve the functions of bulldozing and the like; a telescopic oil cylinder is additionally arranged on a lower vehicle to achieve the function of operation at different track gauges; the excellent overall performance of the excavator covers the pipe lifting machine, so that all the functions in pipe lifting construction are achieved; and compared with an existing pipe lifting machine on the market, the all-terrain multi-functional pipe lifting machine based on the excavator platform has various functions.

Description

technical field [0001] The invention relates to the technical field of pipelayers, in particular to an all-terrain multifunctional pipelayer based on an excavator platform. Background technique [0002] At present, the pipelayers on the market are all based on the chassis of the bulldozer and designed with side-mounted booms. Such pipelayers have single functions and poor adaptability to working conditions, and cannot meet complex conditions such as steep mountains and swamps. Working conditions, and the boom can only rotate in the direction of luffing and cannot rotate horizontally, so it is impossible to achieve multi-angle hoisting operations at the same position. [0003] At present, the pipelayers in the domestic market have a single function, and only have the function of lifting pipelines for pipeline laying construction, and the adaptability of the bulldozer platform to the terrain is poor. In terms of the climbing ability of the whole machine, the general pipelayer ...

Problems solved by technology

[0002] At present, the pipelayers on the market are all based on the chassis of the bulldozer and designed with side-mounted booms. Such pipelayers have single functions and poor adaptability to working conditions, and cannot meet complex conditions such as steep mountains and swamps. Working conditions, and the boom can only rotate in the direction of luffing and cannot rotate horizontally, so it is impossible to achieve multi-angle hoisting operations at the same position

[0003] At present, the pipelayers in the domestic market have a single function, and only have the function of lifting pipelines for pipeline laying construction, and the adaptability of the bulldozer platform to the terrain is poor. In terms of the climbing ability of the whole machine, the general pipelayer The climbing ability is average when the climbing ability is below 20°, the ground clearance of the chassis is small, the passing rate of the chassis is low, the size of the disembarked car with similar tonnage is slightly small, the stability of the whole machine is relatively poor, and the boom of the pipelayer is only It can swing up and down, but cannot turn on the horizontal plane. The track gauge is fixed and the working width of the whole machine cannot be adjusted.
