[0002] Traditional gas pressure regulating stations are usually set up on the ground, and station buildings need to be built to manage and maintain equipment such as pressure regulators, which not only occupies a large amount of land resources and ground space, but is also not conducive to urban planning. In order to solve the problems existing in traditional gas pressure regulating stations, the current art adopts the method of burying the pressure regulator and the matching pressure regulating box and protective box underground, wherein the pressure regulator is installed in the pressure regulating box, and the protective box is set on the pressure regulating box and exposed to the ground, so that the pressure regulator can be disassembled and assembled by opening the protective box. Because the pressure regulator is heavy, the current art generally uses a crane to lift the pressure regulator (lift the pressure regulator out of the pressure regulating box from bottom to top or put the pressure regulator into the pressure regulator from bottom to bottom). This method not only requires large equipment investment, but also has cumbersome operation. Utility Model Content
