As shown in fig. 1, an embodiment of the present invention provides an orthogonal guide type hoist winch apparatus including a bracket 1, a rotating lever 2 provided on the bracket 1, and a wire winding roller 4 on which a wire rope 3 is wound. Wherein, support 1 comprises two fixed curb plates, and the both ends of dwang 2 rotate with two fixed curb plates respectively and are connected, and motor 5 is installed in the outside of one of them fixed curb plate, for motor 5 provides the supporting role, is convenient for motor 5's stable output. An output shaft of the motor 5 is connected with an end portion of the rotation lever 2 to drive the rotation lever 2 to rotate. The wire winding roller 4 is sleeved on the rotating rod 2 and can slide along the rotating rod 2. The steel wire guiding mechanism that is located fixed position is arranged to the below of steel wire winding roller 4, and the steel wire guiding mechanism is passed to wire rope 3's end, and is connected with couple 6, relies on couple 6 to fix jack-up things such as rail.
When 5 drive dwangs 2 of motor rotate, drive steel wire winding roller 4 in the lump and rotate and receive and release line, the initial point of 3 whereabouts of wire rope is in the position of steel wire guiding mechanism all the time under the effect of steel wire guiding mechanism, relies on wire rope 3's traction force etc. to make unwrapping wire in-process wire winding roller 4 continuously slide, slows down the displacement shake phenomenon that 3 emergence of unwrapping wire in-process wire rope, stability when promoting the unwrapping wire.
Meanwhile, as shown in fig. 2, both ends of the wire winding roller 4 are fixedly connected with rotating rings 7, ball grooves 9 for accommodating first steel balls 8 are formed on the inner sides of the rotating rings 7, and the ball grooves 9 are bowl-shaped and are arranged in a plurality of numbers and distributed around the rotating rings 7. Correspondingly, the outer side wall of the rotating rod 2 is formed with transverse guide grooves 10 corresponding to the ball grooves 9 one to one, and the transverse guide grooves 10 are distributed along the axis of the rotating rod 2. The cross section of the transverse guide groove 10 can also be in a bowl shape, when the rotating ring 7 is sleeved on the rotating rod 2, the ball grooves 9 and the transverse guide grooves 10 are aligned one by one, one part of the first steel ball 8 is positioned in the ball grooves 9, and the other part is positioned in the transverse guide groove 10 and rolls freely.
Through setting up of horizontal guide way 10, ball groove 9 and first steel ball 8, make motor 5 drive dwang 2 rotatory time by first steel ball 8 transmission torsion, drive swivel becket 7 and steel wire winding roller 4 synchronous revolution, and the spacing of horizontal guide way 10 and first steel ball 8 ensures swivel becket 7 and steel wire winding roller 4 only can be for dwang 2 axial slip. The rotating ring 7 is in rolling contact with the rotating rod 2 through the first steel balls 8, so that friction loss can be reduced, the effect similar to that of a rolling bearing is further reduced, and the displacement shaking phenomenon of the steel wire rope 3 in the paying-off process of the steel wire winding roller 4 is relieved.
Wherein, two fixed curb plates of support 1 have limiting displacement, and the biggest distance of the outside slip of swivel becket 7 at 4 both ends of restriction steel wire winding roller makes steel wire winding roller 4 can not slide from dwang 2, and can not direct and fixed curb plate frictional contact and wearing and tearing.
As a further improvement of this embodiment, the wire guide mechanism is a guide ring 11 that damps the vertical movement of the wire rope 3, and therefore, not only does it have a guiding function, but it can also damp the movement of the wire rope 3 in an auxiliary manner, and further reduce the displacement chattering.
Referring to fig. 3 and 4, the guide ring 11 includes a fixed inner ring 12 and a vertical guide spiral ring 13, and a circular slot 14 for rotatably supporting the vertical guide spiral ring 13 is formed on an inner side of the fixed inner ring 12.

In addition, the outer diameter of the vertical guiding spiral ring 13 is matched with the inner diameter of the annular clamping groove 14, so that the outer side of the vertical guiding spiral ring is contacted with the annular clamping groove 14 after installation, and the vertical guiding spiral ring 13 can be ensured to stably rotate in the annular clamping groove 14 without deflection.
Meanwhile, the outer side wall of the vertical guide spiral ring 13 is provided with a vertical guide groove 17, the whole vertical guide groove 17 is spiral, one end of the steel wire rope 3 is wound on the outer side wall of the steel wire winding roller 4, and the other end of the steel wire rope penetrates out of the vertical guide groove 17 downwards and is connected with the hook 6. The steel wire rope 3 is always contacted with the vertical guide groove 17 in the descending process, and when the steel wire rope 3 descends for a certain distance, the contact point with the vertical guide groove 17, namely the spiral point, needs to be correspondingly changed, so that the shaking of the steel wire rope 3 can be effectively slowed down under the action of the second steel balls 16 along with the rotation of the vertical guide spiral ring 13. The rotation of the vertical guiding spiral ring 13 is adopted to replace the adverse factors of reciprocating motion caused by common spring vibration reduction, and the steel wire rope 3 can be better stably wound and unwound to reduce vibration.
As a further improvement, in the present embodiment, an annular fillet 18 is formed at an inner corner position of the top of the fixed inner ring 12, and the fillet 18 is arranged to reduce wear of the steel wire rope 3 and prolong the service life of the steel wire rope 3.
When the device provided by the invention is applied, the motor 5 drives the rotating rod 2 to rotate, the rotating ring 7 and the steel wire winding roller 4 are driven to rotate together, the tail end of the steel wire rope 3 passes through the hook 6 of the guide ring 11 to hang heavy objects such as a track board to be lifted, and then the steel wire rope 3 moves up and down and rotates in the annular clamping groove 14 along with the vertical guide spiral ring 13 under the action of the vertical guide groove 17, and it needs to be noted that at the moment, because the steel wire rope 3 is in a descending state in the paying-off process, the steel wire rope 3 in the vertical guide groove 17 can rotate along with the vertical guide spiral ring 13, so that the shaking of the steel wire rope 3 is effectively slowed down, and the stable reeling and unreeling of the steel wire rope 3 are better completed.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
