Abstract
The utility model provides a pulley with a convenient-to-replace cable, which comprises a main shaft and a connecting frame. Two fan-shaped pulley racks are fixed on the main shaft. A wheel hub is also arranged on the main shaft between the two pulley racks. The outer periphery of the wheel hub is provided with a wheel groove. The wheel hub and the main shaft are connected together through a bearing. The arc-shaped edge of each pulley rack is provided with two convex blocks and the bottom of the connecting frame is provided with a seat body. One end of the seat body is positioned between the two convex blocks of one pulley rack and the end portion of the seat body is connected with the two convex blocks through a fixed pin. The other end of the seat body is positioned between the two convex blocks of the other pulley rack and the end portion of the seat body is connected with the two convex blocks through a moveable pin A. The pulley with a convenient-to-replace cable is simple and compact in structure and the cable of the pulley is simple and convenient in replacement. The actual bearing capacity of the pulley is 120 KN.
Description
Technical field
The utility model belongs to the pulley technical field, is specifically related to a kind of pulley that is convenient for changing cable.
Background technique
Pulley is that a periphery has groove, the wheel that can sway.By the simple and mechanical pulley that is called that can rotate around central shaft that can rotate that fluted wheel hub and the gentle rope (rope, cable, cable wire, chain etc.) that strides across wheel hub formed around central shaft.The pulley that uses on the oil field at present, main shaft is provided with two fan-shaped pulley frames and a wheel hub, and wheel hub all passes through bearing between two pulley frames, wheel hub and the main shaft and is connected between two pulley frames; The arc cylinder side face of each fan-shaped pulley frame is provided with contiguous block; When on the race of wheel hub, overlapping cable; Elder generation's rotary pulley frame staggers two pulley frames, then with cable joint-box on race; Rotary pulley frame again after cover is good; Two pulley frames are overlapped, and the contiguous block on two pulley frames is docking together, and with bolt the contiguous block on two pulley frames being fixed together at last gets final product.The shortcoming of this pulley is: the cover cable is inconvenient on race, and it is complicated to change cable operated, and pulley is stressed less than 65KN.
Summary of the invention
The purpose of the utility model provides a kind of pulley that is convenient for changing cable, has solved existing pulley and has changed the inconvenient problem of cable.
The technological scheme that the utility model adopted is: a kind of pulley that is convenient for changing cable; Comprise main shaft and link press span; Be fixed with two fan-shaped pulley frames on the main shaft; Also be provided with wheel hub on the main shaft between two pulley frames, the outer peripheral surface of wheel hub is provided with race, is connected through bearing between wheel hub and the main shaft; The curved edge place of each pulley frame is provided with two projections; The link press span bottom is provided with pedestal; One end of pedestal is connected through fixing pin between two projections in the end of this pedestal and this between two projections of a pulley frame wherein; The other end of pedestal is connected through loose pin A between two projections in the end of this pedestal and this between two projections of another pulley frame.
Wherein, loose pin A comprises bearing pin, and an end of bearing pin is fixed with the pin head, and an end of the other end of bearing pin and motion bar is hinged.
The beneficial effect of the utility model is, and is simple and compact for structure, and it is simple and convenient to change cable, this pulley can actual strength be 120KN.

Among the figure, 1. main shaft, 2. link press span, 3. pulley frame, 4. wheel hub, 5. race, 6. projection, 7. pedestal, 8. fixing pin, 9. loose pin A, 10. bearing pin, 11. pin heads, 12. motion bars, 13. draw rings, 14. loose pin B.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
As depicted in figs. 1 and 2, the utility model provides a kind of pulley that is convenient for changing cable, comprises main shaft 1 and link press span 2; Be fixed with on the main shaft 1 on the main shaft 1 between 3, two pulley frames 3 of two fan-shaped pulley frames and also be provided with wheel hub 4, the outer peripheral surface of wheel hub 4 is provided with race 5, is connected through bearing between wheel hub 4 and the main shaft 1; The curved edge place of each pulley frame 3 is provided with two projections 6; Connect 2 bottoms and be provided with pedestal 7; One end of pedestal 7 is connected through fixing pin 8 between two projections 6 in the end of this connecting base 7 and this between two projections 6 of a pulley frame 3 wherein; The other end of pedestal 7 is connected through loose pin A9 between two projections 6 in the end of this pedestal 7 and this between two projections 6 of another pulley frame 3.
As shown in Figure 3, loose pin A9 comprises bearing pin 10, and an end of bearing pin 10 is fixed with pin head 11, and an end of the other end of bearing pin 10 and motion bar 12 is hinged, and pin 11 is provided with draw ring 13.
When the utility model pulley is changed cable, with motion bar 12 rotations of loose pin A9, motion bar 12 and bearing pin 10 are positioned on the straight line earlier; Hold draw ring 13 again, A9 pulls out with loose pin, and is as shown in Figure 4; Because an end of pedestal 7 is connected through fixing pin 8 between two projections 6 in the end of this connecting base 7 and this between two projections 6 of a pulley frame 3 wherein, pulls link press span 2 pedestal 7 is rotated up around fixing pin 8; Then the cable in the race 5 is changed; Pull link press span 2 pedestal 7 is rotated down around fixing pin 8 to returning again, the other end that makes pedestal 7 is between two projections 6 of another pulley frame 3, and insertion loose pin A9 is (at this moment in this end of pedestal 7 and two projections 6 again; The motion bar 12 of loose pin A9 and bearing pin 10 are point-blank); Last rotary moveable bar 12 makes motion bar 12 vertical with bearing pin 10, and loose pin A9 just is fixed on the other end of connecting base 7 between two projections 6 of another pulley frame 3 like this.
Link press span 2 takes the shape of the letter U; Be installed with loose pin B14 on the link press span 2, its structure is the same with loose pin A9 structure, when the utility model pulley need be hung in when aerial; Only need hook be hung over loose pin B14 upward gets final product; When the utility model pulley need fix on the ground, pulley was fixed on through link press span 2 on the tripod on ground, with loose pin B14 link press span 2 and tripod was locked.
