Abstract

The invention provides an inflation control device of an inflatable anchor. The inflation control device comprises a pressure sensor arranged in a bag body of the inflatable anchor and used for acquiring a gas pressure signal produced by the bag body due to inflation; a piezoelectric conversion component connected with the pressure sensor and used for acquiring the gas pressure signal, and converting the gas pressure signal into current; an electromagnetic induction component connected with the piezoelectric conversion component and used for converting the current into a magnetic field, wherein the electromagnetic induction component makes action according to the magnetic field; and the inflation control component connected with the electromagnetic induction component and used for connecting with or disconnecting from the inflation device according to the action. The inflation device for the inflatable anchor can realize automatic inflation or stop inflation according to the pressure in the bag body of the inflatable anchor; and the control device is simple in operation, high in construction efficiency, adjustable in inflation pressure and capable of realizing quantitative inflation function.

Description

technical field [0001] The invention belongs to the technical field of inflatable anchor rods, and in particular relates to an inflation control device for inflatable anchor rods. Background technique [0002] Inflatable anchor is a new form of anchor, which has the advantages of economy, environmental protection and large bearing capacity. It has been widely used in soft engineering. Existing equipment cannot carry out quantitative inflation according to the design air pressure value, and the inflation process is entirely based on experience, and it is impossible to judge whether the inflation bolt has been inflated; The occurrence of accidents such as bag or deflation. In addition, the inflatable process of the inflatable anchor can only be simplified to a low level, and the operation is cumbersome, which seriously affects the construction efficiency of the inflatable anchor. Contents of the invention [0003] In order to overcome the above-mentioned technical defects,...
