Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] In this embodiment, the propulsion cylinder of a 6m tunnel boring machine is taken as the control object as an example. The main control requirements of the tunnel boring machine cylinder (including cylinder diameter, rod diameter, stroke, working pressure, and speed requirements during extension and retraction) are measured and calculated. Output: When the oil cylinder is extending, the flow rates of the rodless cavity and the rod cavity are 67L / min and 19L / min respectively; 35L / min. Then carry out specification matching according to the calculated flow rate. The compact two-way cartridge valve for controlling the rodless chamber of the tunnel boring machine cylinder is selected with a diameter of DN16, and the compact two-way cartridge valve for controlling the rod chamber of the tunnel boring machine cylinder is selected for DN10. Diameter sp...

Abstract

The invention relates to a tunnel boring machine propulsion valve group adopting full cartridge valve control. A base joint group body comprises an oil feeding joint unit, a plurality of working jointunits, a tail joint unit and connecting, detecting and communicating accessories; the plurality of working joint units are connected between the oil feeding joint unit and the tail joint unit in series; the oil feeding joint unit is provided with a compact two-way cartridge valve; the compact two-way cartridge valve is connected with a combined flange control cover plate provided with a threadedpilot control valve; the combined flange control cover plate provided with the threaded pilot control valve controls the opening or closing of the compact two-way cartridge valve; each working joint unit is provided with two groups of compact two-way cartridge valves, and each group of compact two-way cartridge valves consists of two compact two-way cartridge valves; and the two groups of compacttwo-way cartridge valves are respectively connected with a rodless cavity and a rod cavity of a propulsion oil cylinder of a tunnel boring machine through combined flange control cover plates providedwith pilot control valves. The propulsion valve group of the tunnel boring machine controlled by the full cartridge valves has good manufacturability, assemblability and maintainability, and the configuration scheme of the propulsion valve group makes the tunnel boring machine to be more efficient and energy-saving and meet lower emission requirements.

Description

technical field [0001] The invention relates to a tunnel boring machine propulsion valve group, in particular to a tunnel boring machine propulsion valve group controlled by a full cartridge valve. Background technique [0002] At present, traditional "plate valves", "superimposed valves" and their combined products based on mounting surface connections at home and abroad are facing high-power-density hydraulic products such as "threaded cartridge valves" and "two-way cartridge valves" based on cartridge connections. challenge. The high-power-density modular hydraulic control unit based on plug-in connection is in a rapid development stage. It is a highly reliable component-level product for hydraulic equipment in the medium flow (100-400L / min) demand, and has strong technical and cost advantages. [0003] Traditional products based on two-way cartridge valve technology are mainly used in the medium and large flow and power ranges of industrial hydraulics. The application h...
