Abstract
The utility model discloses a kind of swing type pulley with self correction function, including pulley base, pulley and pulley spindle, pulley is arranged on pulley base by pulley spindle, the top of the pulley base sets hanging axis, the top of the hanging axis connects spheroid through ball seat, spheroid and the dynamic cooperation of ball seat, guide housing is provided between the pulley base and pulley.The utility model is in use, pulley is in addition to can be around pulley spindle central rotation, it can also slowly rotate on ball seat and slightly swing by spheroid, the angle excursion between steel wire rope and pulley is adjusted, pulley is adapted to the motion of steel wire rope, reduces the angle excursion that steel wire rope moved into, laid out pulley, guide housing then prevents steel cable slot disengaging, the service life of steel wire rope, pulley is improved, reduces and safeguards cost of use, improves the reliability of crane gear.
Description
Technical field
The utility model belongs to crane hoisting equipment technical field, and in particular to a kind of simple in construction, service life length
The swing type pulley with self correction function.
Background technology
Crane species of the prior art is various, but is adopted mostly in the steel cable winding system of crane hoisting mechanism
With the pulley of only one degree of freedom, once occur steel wire rope move into, lay out assembly pulley angle excursion it is larger when, steel wire rope is just
Meeting friction pulley inwall, causes steel wire rope, pulley life-span not high, safeguards that cost of use is higher；In particular cases steel wire rope can be straight
Connect and depart from from pulley groove, now the steel wire rope of stress is extruded is caused to be broken by destruction, causes the security of crane gear
It is not high with reliability.
Therefore, it is the key solved the problems, such as to develop a kind of high pulley of safety and reliability.
Utility model content
The utility model aims to provide a kind of simple in construction, the cunning of the swing type with self correction function of service life length
Wheel.
What the purpose of this utility model was realized in：Including pulley base, pulley and pulley spindle, pulley is set by pulley spindle
It is placed on pulley base, the top of the pulley base sets hanging axis, and the top of the hanging axis connects spheroid, spheroid and ball through ball seat
Seat is dynamic to be coordinated, and guide housing is provided between the pulley base and pulley.
Beneficial effect：In use, pulley can also lead to the utility model in addition to can be around pulley spindle central rotation
Cross spheroid slowly to rotate and slightly swing on ball seat, adjust the angle excursion between steel wire rope and pulley, adapt to pulley
In the motion of steel wire rope, the angle excursion that steel wire rope moved into, laid out pulley is reduced, guide housing then prevents steel cable slot disengaging, carried
High steel wire rope, the service life of pulley, reduce and safeguard cost of use, improve the safety and reliability of crane gear.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is dimensional structure diagram of the present utility model；
Label in figure：1 ~ pulley base, 2 ~ mounting hole, 3 ~ pulley, 4 ~ pulley spindle, 5 ~ hanging axis, 6 ~ ball seat, 7 ~ spheroid, 8 ~ lead
To cover.
Embodiment
The swing type pulley with self correction function shown in 1 ~ 2 with reference to the accompanying drawings, including pulley base 1, pulley 3 and pulley spindle
4, pulley 3 is arranged on pulley base 1 by pulley spindle 4, and the top of the pulley base 1 sets hanging axis 5, the top of the hanging axis 5
Spheroid 7, spheroid 7 and the dynamic cooperation of ball seat 6 are connected through ball seat 6, guide housing 8 is provided between the pulley base 1 and pulley 3.
Described guide housing 8 includes the curved cover plate being respectively arranged on 1 forward and backward face of pulley base, and the curved cover plate passes through
Two curved cover plates are fixed on pulley base 1 by screw；Avoid steel wire rope from departing from from pulley groove, cause steel wire rope to be squeezed
The problem of pressure is caused fracture by destruction.
Mounting hole 2 is set on described pulley base 1, and the hanging axis 5 coordinates with the screw thread of mounting hole 2.
Described spheroid 7 coordinates with the screw thread of hanging axis 5.
Working method of the present utility model：Ball seat 6 is installed on the arm of crane gear, steel wire is set on pulley 3
Rope, during lift cargo, when steel wire rope moves into, lays out the angle excursion of the appearance of pulley 3, drawing of the hanging axis 5 in steel wire rope
Slowly rotated on ball seat 6 by spheroid 7 under power, adjust the angle excursion between steel wire rope and pulley 3 in real time, eliminate angle of deviation
Spend or angle excursion is in minimum, guide housing 8 then avoids steel wire rope from detaching pulley because angle of deviation is big in operation process
Groove.
