Abstract

The invention provides a crane and relates to the field of explosion-proof crane technologies and safety. The crane is suitable for special chemical industry and military environment and mainly comprises a trolley, a cart running mechanism, a hoisting mechanism, a hydraulic system and the like. For the crane, the self weight of the crane can be effectively lowered; in addition, by adopting hydraulic transmission and safe voltage control, the safety performance and the stability performance of lifting equipment can be better ensured; and the technical problems of easiness in damage of explosion-proof electrical elements, difficulty in electrical arrangement, easiness in electric leakage injury caused by explosion-proof equipment, high requirements for grades of an anti-explosion electric hoist and a motor, poor smoothness in starting and braking of the motor, easiness in abrasion of a steel wire rope and swing of the steel wire rope, instability in the steel wire rope and the like in the prior art solved, so that the crane is convenient to use and overhaul, the artificial intelligence (AI) chemical plant can be easily realized in the future, the cost is lowered, and the safety is improved.

Description

Technical field [0001] The invention relates to the field of explosion-proof crane technology and safety, in particular to the field of innovation of explosion-proof cranes. Background technique [0002] The explosion-proof crane under the existing technical conditions is mainly a double-beam bridge crane with an explosion-proof electric hoist as the lifting mechanism. It must meet the requirements of the JB / T10219-2001 "Explosion-proof beam crane" standard. The working power supply is three-phase AC and rated The voltage is 380V; the working environment temperature is -20~40℃; the relative humidity should not exceed 50% when working indoors at 40℃, and the relative humidity can be as high as 100% when working outdoors at 25℃; the altitude of the installation site should not exceed 2000m. [0003] There are many electrical components on the existing lifting equipment, which will produce sparks during use. If they are in a flammable and explosive environment, they will cause serious...
