Technical Field
The invention relates to the field of engineering machinery, in particular to an air pressure maintaining system for a double-wheel stirring drilling machine.
Background
For a two-wheel stirring drilling machine, the working environment is often bad. For example, on the outside of a two-wheeled blender is a slurry mix, while on the inside of a two-wheeled blender is a precision gearbox and hydraulic motor. Since the milling wheel of the double-wheel stirring drilling machine continuously rotates during working, a fixed sealing structure cannot be arranged, and a dynamic sealing structure is generated between the inner side and the outer side of the double-wheel stirring drilling machine. In order to ensure the reliability of the movable sealing structure, the inner side of the double-wheel stirring drilling machine is generally provided with injected oil so as to balance the pressure between the inner side and the outer side of the double-wheel stirring drilling machine. This ensures that the slurry mixture outside the dual-wheel blender does not enter the interior of the dual-wheel blender and damage the gearbox and hydraulic system.
However, as the drilling depth of the double-wheel stirring drilling machine is increased, the geological conditions are more and more complex. For the current double-wheel stirring drilling machine, higher requirements are put on a milling head sealing device. The original pressure balance pressure maintaining system on the inner side and the outer side is not very reliable, and meanwhile, with the development of the modern construction level, a long conveying time is required for pumping hydraulic oil from the ground into a deep underground double-wheel stirring drilling machine for the traditional method adopting the hydraulic oil as a key medium of pressure balance. That is, the existing method for achieving the purpose of pressure balance by using hydraulic oil has the problems of unreliable pressure maintaining, untimely pressure maintaining feedback, inconvenient maintenance and the like.
