Abstract
The utility model discloses a large-tonnage single-girder steel wire rope type electric hoist which comprises a lifting device, a running device and an electric control device, and is characterized in that the electric control device is connected with a first drive device used for driving the lifting device and is also connected with a second drive device used for driving the running device; the lifting device comprises a winding drum device, a lifting hook device and a pulley device; the first drive device is used for driving the winding drum device to rotate, and meanwhile, the winding drum device is used for driving the lifting hook device to move up or down through the pulley device. The electric hoist has the advantages of simple structure, large lifting capacity, safety and reliability.
Description
Technical field
the utility model relates to a kind of electric block, especially a kind of large tonnage single beam steel-wire rope type electric block.
Background technology
in prior art, steel-wire rope type electric block is a kind of small lifting equipment, steel-wire rope type electric block has compact conformation, lightweight, volume is little, component universality is strong, the advantage such as easy to operate, it both can be arranged separately on I-beam section, also can supportingly be arranged on the hoisting cranes such as electronic or manual single-beam, twin beams, cantilever, gantry and use, the maximum tonnage of electric single-beam steel rope cucurbit can only be accomplished 12.5t in the market, and often need hoisting capacity to surpass the electric single-beam steel rope cucurbit of 12.5t, limited steel-wire rope type electric block lifted load.
Summary of the invention
the utility model object is: provide a kind of simple in structure, the large tonnage single beam steel-wire rope type electric block that hoisting capacity is large and safe and reliable.
the technical solution of the utility model is a kind of large tonnage single beam steel-wire rope type electric block, comprise jack up unit, running gear and electrical controller, it is characterized in that, described electrical controller connects for driving the actuating device one of described jack up unit, this electrical controller also connects for driving the actuating device two of described running gear simultaneously, described jack up unit comprises roll device, cargo hook gear and pulley gear, described actuating device one drives described roll device to rotate, and this roll device drives cargo hook gear up-and-down movement by pulley gear simultaneously.
preferably, described pulley gear is provided with chain wheel rope, and this chain wheel rope end is fixed by end anchor fitting.
preferably, also comprise lifting altitude restraint device, described lifting altitude restraint device is connected with described jack up unit.
preferably, described actuating device one drives roll device to rotate by retarder one.
preferably, described running gear comprises operation wheel, and drives this operation wheel lateral rotation by the retarder two being connected with described actuating device two.
the utility model concrete operation step is as follows, when pressing the operating order button that hoists, electrical controller accessory drive one drives jack up unit, this jack up unit comprises roll device, cargo hook gear and pulley gear, be that actuating device one drives roll device to rotate, then this roll device drives cargo hook gear up-and-down movement by pulley gear; When pressing cross motion order button, electrical controller accessory drive two drives operation wheel, thereby the weight lifting on cargo hook gear is laterally moved.
the utility model has the advantages that: not only simple in structure, hoisting capacity is large, and safe and reliable.
Accompanying drawing explanation
