Abstract

A special movable pulley for a crane comprises a main pulley, a supporting plate, a stud bolt, a pin shaft, cotter pins, fastening press plates, bolts and the like in order. Compared with the prior art, a lifting ring is replaced by the fastening press plates fixed by the pin shaft and four cotter pins, and the fastening press plates which are manufactured into stamped parts are fixed by two bolts and separated by the same so as to form a drawing steel wire rope mounting hole and a main cable mounting hole, thereby separating a drawing steel wire rope from a cable, and avoiding earth leakage caused by mutual winding and friction of cables.

Description

Hoisting crane special mobile pulley
Technical field
The utility model relates to elevator machinery, is applicable to the fixing of hoisting crane cable trunk line, haulage cable.
Concrete background technology
Hoisting crane special mobile pulley is the indispensable instrument of suspended cables line, haulage cable, when the hoisting crane main line moves at random the cloth cable, power immediately to each motor.Mobile pulley in the market is made of head pulley, stay bearing plate, bearing pin, two-thread screw, suspension ring etc.Cable, haulage cable are fixed on the suspension ring with finer wire, and freely rolling by head pulley stretches or folding and unfolding cable in an orderly manner again on steel rope.But head pulley is owing to often roll, and causes fixedly that the nut at two-thread screw two of head pulley becomes flexible, thereby can make the head pulley lack of equilibrium, makes troubles to production work, even the danger that comes off and hurt sb.'s feelings is arranged.For these drawbacks, most of users adopt the nut spot welding at the fixing two-thread screw two ends of head pulley dead; But bring difficulty for maintenance next time.Moreover haulage cable and cable be fixed together, and causes that easily haulage cable and cable twine friction mutually, causes electric leakage after cable is damaged.
Summary of the invention
In order to overcome existing mobile pulley all deficiencies in use, the utility model provides a kind of hoisting crane special mobile pulley, can effectively avoid the fixedly two-thread screw two ends nut loose or dislocation of head pulley, also prevent that haulage cable and cable from causing electric leakage owing to friction is aging simultaneously.
Technical scheme
The technical scheme of this utility model is: be made of in order head pulley, stay bearing plate, thru-bolt, spring cotter, bearing pin, clam member, bolt.Head pulley is to be connected by thru-bolt with stay bearing plate, and with fixing about bullet pad, nut, its lower end clam member is installed in the centre of stay bearing plate by bearing pin and spring cotter, bores 4 spring cotter pin-and-holes on the bearing pin, the assurance stay bearing plate is parallel to each other, and clam member is separated respectively by bolt.And become the backbone cable hole of treasured calabsh shaped shape and lead the hole threaded hole of steel.In use, earlier two bolts on the clam member are turned on, again steel rope is packed in the haulage cable hole, after with the upper end bolted, just can fix steel rope, cable is installed in the backbone cable hole, the bolt of the bottommost of screwing on is at last driven the stretching or the folding and unfolding of cable and haulage cable by the rolling of head pulley again.
The utility model and original technology relatively are that suspension ring are changed into by bearing pin and the fixing clam members of four spring cotters, clam member are made blanked part and with two bolt and separate the haulage cable hole and backbone cable hole two mounting holes.So haulage cable and cable are spaced from each other, and avoid cable to cause electric leakage because of frictional failure.
Description of drawings
Fig. 1 is the utility model constructional drawing
Below in conjunction with accompanying drawing the utility model is described further.
In Fig. 1 b: 1. head pulley; 2. stay bearing plate; 3. bullet pad; 4. nut; 5. thru-bolt; 6. bearing pin; 7. clam member; 8. bolt; 9. backbone cable hole; 10. haulage cable hole; 11. spring cotter
The specific embodiment
In Fig. 1 b, boring 4 spring cotter pin-and-holes on the bearing pin 6, can guarantee that stay bearing plate 2 is parallel to each other, head pulley 1 is to be connected by thru-bolt 5 with stay bearing plate 2, and it is fixing with bullet pad 3, nut about 4, its lower end clam member 7 is installed in the centre of stay bearing plate 2 by bearing pin 6 and spring cotter 11, and clam member 7 is separated respectively by bolt 8 and forms backbone cable hole 9 and haulage cable hole 10.
When mounted bolt 8 is turned on earlier that the dress steel rope is installed in cable in the backbone cable hole 9 again to traction steel wire hole 10 in, tightened four bolts 8 at last respectively, reach steel rope and cable separates respectively, the mutual purpose that does not rub.
