Embodiment Construction
[0017] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0018] An emergency control method for the instability of a support system during lifting operations, comprising the following steps:
[0019] (1) First of all, the operation should be stopped immediately, and the hanging objects should be slowly lowered to the ground and stabilized;
[0020] (2) Because the crane leg is tilted due to internal leakage of the hydraulic cylinder, stop the vehicle immediately for inspection;
[0021] (3) If it cannot be solved, it should be reported to professional maintenance personnel for repair;

Abstract
The invention discloses an emergency control method of unstability of a supporting system during crane hoisting operation. The emergency control method comprises the steps that (1) firstly, operationis immediately stopped, a hoisted object is slowly lowered to the ground and is stably placed; (2) if a crane body inclines due to inner leakage of hydraulic cylinders in carne supporting legs, a crane is immediately stopped for inspection; (3) if problems cannot be solved, the problems are reported to professional maintenance personnel for repairing; and (4) if the crane body inclines due to collapse of the ground where the crane supporting legs are positioned, a collapse part is filled with rubble and is covered with a steel plate, or a plurality of square timber is vertically stacked on theupper and lower sides, and the area is not smaller than 500 mm * 500 mm. The emergency control method has the beneficial effects that when the crane breaks down, staff can perform emergency treatmentaimed at faults, serious accidents caused by the faults are effectively avoided, and the faults can be prevented from further expanding.
Description
technical field [0001] The invention relates to the technical field of subway construction, in particular to an emergency control method for the instability of a support system during hoisting and hoisting operations. Background technique [0002] Subway is a form of railway transportation, which refers to the urban rail transit system that mainly runs underground, that is, the abbreviation of "underground railway" or "subway" (Subway, tube, underground); many such systems are designed to match the built environment. And considering the construction and operating costs, it may be converted into ground or elevated road sections outside the city center. The subway is a proprietary, high-density, high-capacity urban rail transit system (Metro) that covers various underground and above-ground right-of-way in urban areas. The subway in Taiwan, China is called "Rapid transit". [0003] In addition to the subway, it also includes the elevated railway (Elevated railway) or the rail...
