Further, fastening nut is slotted nut, and being equipped with split pin prevents fastening nut from loosening.
Further, the diameter of shaft is more than the internal diameter of through hole and the diameter less than connecting rod, the length of shaft on pressing plate Slightly larger than the distance between ball bearing outer end face and plane bearing outer end face.
Further, pulley yoke section is U-shaped, and both sides are pulley otic placode, along in shaft on two side roller otic placodes The direction of heart line is equipped with limit otic placode, and gag lever post is equipped between limit otic placode.
The utility model has the beneficial effects that:
The utility model middle pulley frame is connected on crane arm beam, and axis can be rotated around the shaft;When steel wire rope with lead To when having angle between wheel, pulley yoke can deflect with the cross component force of steel wire rope, to reduce between steel wire rope and pulley Friction avoids racking the safety accident of pulley edge initiation because of steel wire rope.

Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment, and following embodiment is only retouched The property stated, it is not restrictive, protection scope of this utility model cannot be limited by this.
The utility model belongs to derrick crane technical field, is related to a kind of guiding for optimization of traction mechanism in power hoist Wheel, including pulley 1, pulley yoke 2 and crane arm beam 3 are as shown in Figure 1 the overall structure diagram of the utility model, at wherein A For the structural schematic diagram inside crane arm beam 3;The enlarged drawing being illustrated in figure 2 in Fig. 1 at A;It is illustrated in figure 3 in Fig. 1 at B-B Sectional view.
It cuts hole on crane arm beam 3 to weld columnar fixing sleeve 4 in the inner, axis and the crane arm beam 3 of fixing sleeve 4 hang down Directly, shaft 5 is penetratingly equipped in fixing sleeve 4;One end of fixing sleeve 4 is equipped with ball bearing 41 and coordinates with shaft 5, ball bearing 41 Outside is equipped with bearing (ball) cover 42;The other end of fixing sleeve 4 is equipped with plane bearing 43 and coordinates with shaft 5, and 43 outside of plane bearing is set There are circular pressing plate 44, pressing plate 44 to be equipped with through hole;Shaft 5 is connected with connecting rod 51 close to one end of ball bearing 41, even 51 other end of extension bar and pulley yoke 2 are affixed;Shaft 5 is connected with close to one end of plane bearing 43 with externally threaded locating rod 52, locating rod 52 is matched equipped with fastening nut 521 with 52 screw thread of locating rod through the through hole on pressing plate 44,44 outside of pressing plate It closes.In this way, pulley yoke 2 can be made to be connected on crane arm beam 3, and 5 axis can rotate around the shaft;When between steel wire rope and directive wheel When having angle, pulley yoke 2 can deflect with the cross component force of steel wire rope, to reduce the friction between steel wire rope and pulley 1, It avoids racking the safety accident of 1 edge of pulley initiation because of steel wire rope.
Shaft 5 when rotation, may be such that fastening nut 521 loosens in fixing sleeve 4, and even fastening nut 521 falls off, Directive wheel is detached from from crane arm beam 3, eventually leads to the generation of safety accident.In the utility model further, fastening nut 521 be slotted nut, and is equipped with split pin;In this way, fastening nut 521 can be effectively prevent to loosen, ensure the use of directive wheel Safety.
5 length of shaft is long to be easy to make the sliding in fixing sleeve 4 of shaft 5, causes pressing plate 44, ball bearing 41, plane axis It holds 43, bearing (ball) cover 42 to fall off out of fixing sleeve 4, makes directive wheel cisco unity malfunction.In the utility model further, shaft 5 diameter is more than the internal diameter of through hole and the diameter less than connecting rod 51 on pressing plate 44, and the length of shaft 5 is slightly larger than ball bearing The distance between 41 outer end faces and 43 outer end face of plane bearing;In this way, the sliding in fixing sleeve 4 of shaft 5 can be prevented, it is ensured that be oriented to The normal work of wheel.
When generating angle between steel wire rope and directive wheel, steel wire rope is easily detached from from pulley 1, causes safety accident.This reality With further, 2 section of pulley yoke is U-shaped in novel, both sides are pulley otic placode, along perpendicular to shaft on two side roller otic placodes The direction of center line is equipped with limit otic placode, and gag lever post 21 is equipped between limit otic placode;In this way, steel wire rope can be effectively prevent from pulley Upper disengaging ensures safe operation.
Above-described is only preferred embodiments of the present invention, it is noted that for the ordinary skill of this field For personnel, under the premise of not departing from utility model design, various modifications and improvements can be made, these belong to this reality With novel protection domain.
