Insulating explosion-proof formula hoist
Technical Field
The utility model relates to a hoist field especially relates to an insulating explosion-proof formula hoist.
Background
The explosion-proof crane under the prior art condition is mainly a double-beam bridge crane taking an explosion-proof electric hoist as a hoisting mechanism, and must meet the regulation of JB/T10219-2001 'Standard of explosion-proof Beam Crane', a working power supply is three-phase alternating current, and the rated voltage is 380V; the working environment temperature is-20 to 40 ℃; the relative humidity can not exceed 50% when the indoor temperature is 40 ℃, and the relative humidity can be up to 100% when the outdoor temperature is 25 ℃; the altitude of the place for installation and use is not more than 2000 m. The existing hoisting equipment is provided with a plurality of electrical components, sparks can be generated in use, if serious accidents can be caused in a combustible and explosive environment, especially in chemical enterprises, the requirement on explosion prevention is high, the existing hoisting equipment is mostly imported explosion-proof hoisting equipment, and the existing hoisting equipment is complex in structure, high in price and difficult to maintain.
In the hoisting mechanism of the explosion-proof crane in the prior art, a reel rising mechanism is adopted, so that a hoisting steel wire rope can be wound around more pulleys, the bending times are more in the working process, the service life of the hoisting steel wire rope is reduced, and the service life of each steel wire rope is different due to different hoisting steel wire rope numbers, so that the maintenance workload is increased, and the waste is possibly caused; moreover, the deflection angle of the hoisting steel wire rope entering and exiting the winding drum is large, and almost reaches the limit range specified by the design and manufacture standard, so that the steel wire rope is excessively worn, the service life is shortened, the rope groove of the winding drum is easy to be sharpened due to the excessive wear of the hoisting steel wire rope, and the situation is more serious when the hoisting height is higher; and the weight of the trolley frame is unbalanced, so that the problem of unbalanced load of the trolley frame can be seriously solved. Most importantly, the hoisting mechanism of the crane in the prior art cannot solve the problem that the hoisting tool shakes seriously, the hoisting tool is easy to touch other equipment in a workshop, sparks are generated to cause danger, and the hoisting area of the conventional hoisting device cannot be adjusted.
