The full-hydraulic digitized synergetic linkage control pipe lifting machine comprises a wireless communication module and an electric-hydraulic control system, wherein the plurality of the pipe lifting machines communicate through the wireless communication module, and the electric-hydraulic control system comprises a DSP controller, a closed walking system, an opened working system, and a fan cooling and accumulator liquid filling system. With the full-hydraulic digitized synergetic linkage control pipe lifting machine of the present invention, the working condition of the pipe lifting machine can be real-timely monitored, the host machine anti-tipping alarm function is provided, the counterweight opening angle can be automatically matched so as to achieve the optimal dynamic balance state, and the operation has the excellent micro-mobility through the high precision electric proportional signal; and with the wireless communication module, the synergetic linkage action of the multiple machines can be achieved.

Description

technical field [0001] The invention relates to a full-hydraulic digital collaborative joint control pipelayer. Background technique [0002] Judging from the feedback of the domestic pipelayer market in recent years: there are more and more construction projects for oil, natural gas, and water conservancy pipelines, the scale is getting larger, and the quality requirements are getting higher and higher. Pipeline construction only relies on traditional Advanced lifting equipment and manual auxiliary installation have been unable to meet the progress and quality requirements of large-scale pipeline construction, so the demand for pipelayer products has also increased accordingly. Traditional manual-assisted installation cannot meet the progress and quality requirements of large-scale pipeline construction, and it is easy to cause safety accidents. [0003] At present, pipelayers at home and abroad are secondary developed on the basis of bulldozers, that is, they are driven b...

[0002] Judging from the feedback of the domestic pipelayer market in recent years: there are more and more construction projects in oil, natural gas, and water conservancy pipelines, with larger scales and higher quality requirements. Pipeline construction only relies on traditional Advanced lifting equipment and manual auxiliary installation have been unable to meet the progress and quality requirements of large-scale pipeline construction, so the demand for pipelayer products has also increased accordingly

Traditional manual assisted installation cannot meet the progress and quality requirements of large-scale pipeline construction, and it is easy to cause safety accidents

[0003] At present, pipelayers at home and abroad are secondary developed on the basis of bulldozers, that is, they are driven by mechanical transmission and driven by an open quantitative hydraulic system; although their walking inherits the characteristics of fast speed of bulldozers, they cannot overcome the Walking stability, poor operating comfort and other mechanical transmission characteristics. In addition, due to the excessive emphasis on the secondary parameter walking speed, it has to increase the engine power to achieve it; Disadvantages of low and poor precision in compound action work

[0004] At the same time, the original fan cooling system uses a belt pulley to directly drive the fan, which cannot meet the actual cooling function required, resulting in a waste of energy
