Abstract

The invention discloses a method, device and apparatus for stepless regulation of propelling pressure of a tube push bench. The method comprises the following steps that pressure data at an outlet of a tube push bench propulsion hydraulic system are collected; a control instruction signal is sent out according to the pressure value of the propelling pressure needing to be adjusted; and the pressure of the hydraulic system is controlled after the control instruction signal is amplified proportionally. The control instruction signal is an electric signal, so that transmission is facilitated, and remote control is achieved; the method for stepless regulation of the propelling pressure of the tube push bench can continuously and proportionally the pressure of the hydraulic system and achieve accurate control over the propelling pressure; and the characteristics that intelligent control is facilitated, the process is simplified, and the production efficiency is improved are achieved, and great significance for actual production is achieved.

Description

technical field [0001] The invention relates to a method, device and equipment for steplessly adjusting the propulsion pressure of a pipe jacking machine, and belongs to the technical field of scanner calibration. Background technique [0002] With the construction of urban rail transit and urban pipe gallery, non-excavation, low pollution, and high-efficiency underground construction methods will surely become a trend. The application of specialized equipment integrating communication and sensing was born. [0003] This intelligent tunnel construction special equipment of existing pipe jacking machine is made up of cutter head, shield body, screw conveyor, annular top iron, U-shaped top iron, propulsion oil cylinder frame body and reaction force frame. When the pipe jacking machine is in the initial state, that is, before the cutter head of the pipe jacking machine performs normal cutting and excavation, its propulsion load and friction force are very small. At this stage,...
