An intelligent digging pipe jacking machine

Abstract

The invention discloses an intelligent excavating and pipe jacking machine. The machine comprises an excavation arm assembly, an anti-collapse cylinder assembly, a conveying mechanism and a control system. The excavation arm assembly comprises an excavation arm, a rotary unit and a swing unit. The anti-collapse cylinder assembly comprises a front cylinder and a rear cylinder. The conveying mechanism comprises a conveying belt and a conveying vehicle. The conveying belt is arranged below the excavation arm assembly. The conveying belt and the conveying vehicle are used for conveying excavated soil. The control system comprises a main control unit, an excavation arm control unit, a cylinder control unit and a conveying control unit. The main control unit is in signal connection with the excavation arm control unit, the cylinder control unit and the conveying control unit. The main control unit is used for controlling the excavation arm control unit, the cylinder control unit and the conveying control unit. The excavation arm control unit, the cylinder control unit and the conveying control unit are used for controlling automatic work of the excavation arm assembly, the anti-collapse cylinder assembly and the conveying mechanism.

Description

technical field [0001] The invention relates to the field of excavating machinery, in particular to an intelligent excavating pipe jacking machine. Background technique [0002] Pipe jacking construction is a non-excavation construction method, and it is a pipeline burying construction technology that does not excavate or excavates less. Pipe jacking construction is to use the jacking force generated by the jacking equipment in the working pit to overcome the friction between the pipeline and the surrounding soil, push the pipeline into the soil according to the designed slope, and transport the earth away. After one section of pipe has been jacked into the soil layer, the second section of pipe will continue to be jacked. Its principle is to push the tool pipe or pipe jacking machine from the working pit through the soil layer to the receiving pit by means of the thrust of the main jacking cylinder, the pipe room, and the relay room. The pipeline is buried between the two...

AI Technical Summary

Problems solved by technology

[0004] The existing excavating arm assembly can only excavate in a single direction, and the bucket can only excavate repeatedly in one direction, and other directions, such as materials located on the side of the bucket, cannot be excavated.

When existing pipe jacking machines excavate places with soft soil layers, landslides often occur above, and the excavation work has to be suspended, seriously affecting production efficiency, and even directly threatening the safety of personnel and equipment. Therefore, a kind of anti-collapse device arranged at the front end of the pipe jacking machine is more and more required on the market

[0005] In addition, due to the low level of automation of existing pipe jacking machines, manual operations or on-site supervision are still required. This method of operation is low in production efficiency and poses a certain safety risk to people. Therefore, there are more and more pipe jacking machines in the market. The more we need an intelligent operation excavating pipe jacking machine
