Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the problem that exists in the above-mentioned background technology, the invention provides a kind of lifting appliance, its oad is little, and is simple in structure, easy for installation, and low cost of manufacture is lightweight, good looking appearance.
the technical solution adopted for the present invention to solve the technical problems is: a kind of lifting appliance, be applicable to driving, lifting on gauntry crane and headstock gear etc. is used, lifting appliance comprises motor-driven reel, the fixed pulley assembly of the close reel on top and the movable pulley assembly of bottom, the fixed pulley assembly is comprised of two fixed pulley groups, the axial direction of fixed pulley group and the axial direction of reel are perpendicular, the movable pulley assembly is splay running block by two axial directions and forms, lifting appliance also has lifting rope, lifting rope across two fixed pulleys on two fixed pulley groups after respectively winding successively between running block and fixed pulley group downwards of two ends, the last two ends, left and right that upwards evenly are around in reel and finally are fixed in reel on running block.
Further: the lifting rope of two fixed pulleys on two fixed pulley groups first is around in downwards respectively and upwards evenly is around in reel on two movable pulleys close on two splayed running blocks, upwards winding successively between the fixed pulley in the fixed pulley group and the movable pulley in running block again, last movable pulley in running block and also finally is fixed in the two ends, left and right of reel.
Further: lifting rope evenly is around at last reel and finally is fixed in two outer ends of reel.
Beneficial effect of the present invention: the advantage of a kind of lifting appliance of the present invention is as follows:
One, the fixed pulley assembly is comprised of two fixed pulley groups, the axial direction of two fixed pulley groups is all perpendicular with the axial direction of reel, this structure is compared with existing structure, because fixed pulley is equivalent to put down in the supporting traverse that is located at top, make the oad of whole lifting appliance diminish, simple in structure, easy for installation, lightweight, good looking appearance.
Two, the movable pulley assembly is comprised of two running blocks, the installation less thick of assembly pulley, and this structure is compared with existing structure, makes equally the oad of whole lifting appliance diminish, and is simple in structure, easy for installation, lightweight, good looking appearance.
Three, the axial direction of two running blocks is splayed, the lifting rope that this structure has reduced to move on the reel is with the drift angle between the lifting rope on close with it movable pulley, reduce between rope and rope and touch friction, can make like this design between reel and fixed pulley group compacter, and can guarantee between the lifting rope of above-below direction noiseless, do not rub, extended the service life of lifting rope yet.
Four, the middle part of lifting rope is at first on two fixed pulley groups, like this can the rugged problem of free adjustment lifting appliance, thus reach the effect of balance type lifting device.
Five, the structure of two fixed pulley groups of employing and two running blocks has increased the multiplying power of pulley, has reduced starting torque, the power of motor of reel, has reduced reductor parameter, drum diameter and lifting rope diameter, has saved the energy, and structure is more simple compact.
Six, the oad due to this lifting appliance is less, so that it does not need to make as large-scale lifting appliance is dismountable, all-in-one-piece frame satisfies the requirement of transportation fully, greatly shortened the cycle of installing, and quality is more guaranteed.
