Explosion-proof bridge crane provided with isolating frames

Abstract

The invention discloses an explosion-proof bridge crane provided with isolating frames. The explosion-proof bridge crane comprises a crane body and the isolating frames. Fixing base frames are arranged on the two sides of the crane body, rail beams are arranged at the upper ends of the fixing base frames, an explosion-proof main beam is slidably connected between the rail beams on the two sides, and the lower end of the explosion-proof main beam is slidably connected with a hoisting trolley. The outer side of the hoisting trolley is horizontally connected with four telescopic frames, and the lower ends of the telescopic frames are vertically connected with the isolating frames. Each isolating frame comprises a fixed frame and a movable frame, wherein the lower end of the fixed frame is connected with the movable frame, and the movable frame is slidably guided out of the fixed frame or guided into the fixed frame. Fireproof fabric is arranged on the inner end faces of the isolating frames. In this way, when hoisted flammable and combustible hazardous articles explode, the isolating frames are erected outside a combustion point to form an isolating zone to retard outward spreading offires, and workers can be evacuated in time.

Description

technical field [0001] The invention relates to the field of bridge cranes, in particular to an explosion-proof bridge crane equipped with an isolation frame. Background technique [0002] The bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting. Because its two ends are located on tall concrete pillars or metal supports, it is shaped like a bridge. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is a kind of hoisting machinery with the widest range and the largest number. When the bridge crane is lifting flammable and explosive dangerous goods, it may explode due to external factors, causing the on-site warehouse to burn. Failure to prevent the spread of the fire in time will cause irreparable losses, and the tr...
