Background technology
In known technology, general hand pulling type single rope grab is equipped with the start-stop system that a cover pulls running rope rope control grab bucket.Its weak point is that the people must stand in the not far place of grab bucket with pulling running rope rope control grab bucket, so not only influences work efficiency, and the influence safety in production.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and provides a kind of method of available motor tool pulling rope to control the single rope grab that grab bucket opens and closes, make this grab bucket applying working condition comformability more extensive, the handling efficiency of grab bucket is higher, more can ensure safety in production.
The purpose of this utility model can reach by following measure:
An end that has the rope control steel rope of shackle links with the clamping bar of controlling on the single rope grab of restricting, the other end and steel wire rope winch steel rope link, the pulling force of the coil spring on the steel wire rope winch less than clamping bar from half of gravity, the pulling force of driven by motor magnetic clutch greater than the friction self-lock force of mechanism for opening/closing and clamping bar from the gravity sum.
The utility model is compared with original technology has following advantage: the method for available motor tool pulling rope is controlled the single rope grab that grab bucket opens and closes, novel, easy to operate, make this grab bucket applying working condition comformability more extensive, the handling efficiency of grab bucket is higher, more can guarantee the safety of operating personal.

The specific embodiment
Describe in detail according to the concrete scheme that the utility model proposes below in conjunction with legend:
Bolster 13 through beams 14 clamping bars 15 bucket bodies 16 inclined plates 17 eccentric disks 18 in rope control single rope grab 1 rope control steel rope 2 shackles 3 steel wire rope winch 4 electric cabinets 5 coil springs 6 cable drums 7 magnetic clutchs 8 supports 9 motors 10 deck beams 11 struts 12
In accompanying drawing 1, the control single rope grab 1 of restricting is hung on the hoist rope of crane, and the shackle 3 that being installed in the rope control steel rope 2 of rope control single rope grab 1 clamping bar 15 1 ends passes the restrict deck beam 11 of controlling single rope grab 10 and the steel rope that support 9 is installed in the steel wire rope winch 4 of crane suspension rod tail end and links.The cable of electric cabinet 5 is connected on the steel wire rope winch 4.
In accompanying drawing 2, steel wire rope winch 4 is made up of coil spring 6, cable drum 7, magnetic clutch 8, support 9, motor 10, the pulling force of coil spring 6 adjust to less than clamping bar 15 from half of gravity, promptly adjust to not stretchy clamping bar 15 of the steel rope that makes on the cable drum 7; Motor 10 drive pulling force that magnetic clutchs 8 rotate adjust to greater than the friction self-lock force of mechanism for opening/closing and clamping bar 15 from the gravity sum, promptly adjust to when motor 10 rotations, drive magnetic clutch 8, the clamping bar 15 that steel rope pulling on the cable drum 7 is compressed by eccentric disk 18, grab bucket is opened, referring to accompanying drawing 9.
In accompanying drawing 3, rope control single rope grab 1 is made up of deck beam 11, strut 12, middle bolster 13, through beam 14, and on the bolster 13, its other end linked with the rope control steel rope 2 that has shackle 3 during an end of clamping bar 15 was hinged on.
In accompanying drawing 4, the switching mechanism of rope control single rope grab 1 mainly is made up of clamping bar 15, inclined plate 17, eccentric disk 18, and on the bolster 13, eccentric disk 18 was installed on the through beam 14 during clamping bar 15, inclined plate 17 were installed in.
In accompanying drawing 5, accompanying drawing 6, accompanying drawing 7, the accompanying drawing 8, be the novel rope control single rope grab 1 mechanism for opening/closing fundamental diagram of expression.In accompanying drawing 5, the last angular plane surface of two eccentric disk 18 upper end flange places and inclined plate 17 is close to, and clamping bar 15 is clamped in the middle of two eccentric disks 18.At this moment, grab bucket opening and closing mechanism is in the friction self-locking state, hoist rope rises, bolster 13 is being with through beam 14 to rise simultaneously in making, rope control single rope grab 1 progressively grasps goods and closes, since the pulling force of the coil spring 6 on the steel wire rope winch 4 less than clamping bar 15 from half of gravity, grab bucket 1 can not be opened.In accompanying drawing 6, discharging place has been arrived in the grab bucket of carrying full goods, presses the unlatching switch on the electric cabinet 5, rotates the motor 10 on the steel wire rope winch 4, make magnetic clutch 8 drive cable drum 7 rotations and generation pulling force, clamping bar 15 and two eccentric disks 18 break away from, motor 10 SELF CL, at this moment, middle bolster 13 is thrown off with through beam 14 and is combined with deck beam 11, see accompanying drawing 7, grab bucket 1 is opened, and goods unloads.Accompanying drawing 8 is that extracting goods place is got back in grab bucket 1, and crane rope descends, and two eccentric disk 18 upper end flange places progressively engage with the last angular plane surface of inclined plate 17, and clamping bar 15 progressively is clipped in the middle of two eccentric disks 18, up to being in accompanying drawing 5 states.
Rope control single rope grab 1 is before loading and unloading operation, earlier the steel rope of the shackle 3 on the rope control steel rope 2 with steel wire rope winch 4 linked, and the pulling force of the coil spring on the steel wire rope winch 46 be transferred to pulling force that the half-sum from gravity less than clamping bar 15 drives magnetic clutchs 8 to motor 10 be transferred to greater than the friction self-lock force of 1 mechanism for opening/closing of grabbing bucket and clamping bar from the gravity sum.At work, rope control single rope grab 1 is placed on the goods that is loaded and unloaded, middle bolster 13 descends with the hoist rope of crane, two eccentric disks, the 18 upper end flange places of through beam 14 and the last angular plane surface of the inclined plate 17 on the middle bolster 13 are close to, clamping bar 15 is clamped in the middle of two eccentric disks 18, i.e. the mechanism for opening/closing of rope control single rope grab 1 is closure state.The hoist rope of crane rises, and full goods is grabbed in grab bucket 1.Rope control single rope grab 1 is hung discharging place, press the unlatching switch on the electric cabinet 5, rotate the motor 10 on the steel wire rope winch 4, make magnetic clutch 8 drive cable drum 7 rotations and generation pulling force, clamping bar 15 and two eccentric disks 18 are broken away from, motor 10 SELF CL, rope control single rope grab 1 is opened, goods is unstowed, and enters next circulation.
