Abstract
The invention discloses a multifunctional fluid testing platform for a shield tunneling machine. The multifunctional fluid testing platform comprises a cutter disc ejection device, a stirring device, a foam system, a bentonite system, a water system, a grease system, an air system, a monitoring system, a collection tank, an external interface integral plate and a base, wherein the cutter disc ejection device comprises a stirring container, a cutter disc ejection hole, a soil pressure sensor, a diaphragm type pressure gauge, a glass view mirror and a stirring rod; and the stirring device comprises a speed reducer, a main shaft, a bearing, a shaft end seal, stirring blades and a stirring rod. Different fluid systems of the shield tunneling machine are integrated, working states under different working conditions, and property parameters of a whole testing system and elements of the testing system can be simulated, meanwhile multiple fluid mediums can be output, and a testing study platform is provided for design, manufacturing and use of the shield tunneling machine.
Description
technical field [0001] The invention relates to the technical field of tunnel construction equipment, in particular to a fluid multifunctional test bench for a shield machine. Background technique [0002] With the rapid development of my country's urbanization process, shield tunneling technology is rapidly popularized, but at present, the performance of each fluid system, the performance and parameters of each component in the design of the shield machine fluid system mainly depends on experience or on-site testing. There is no special equipment for testing the fluid system of the shield machine. In order to shorten the design cycle, speed up the research and development of new products, make the design of the shield machine scientific and reasonable, and improve the technical level of existing products, design a set of shield machine fluid that is safe, environmentally friendly, convenient, easy to expand, and strong adaptability The multi-kinetic test platform is an impo...
