Description

Multi purpose partal crane quick-replaceable suspension hook group
Technical field
The present invention relates to a kind of multi purpose partal crane quick-replaceable suspension hook group, belong to logistics equipment technical field.
Background technology
Along with present Development of Logistics Industry, each port and pier of high pedestal jib crane widespread use, it is mainly used in the loading and unloading operation of ship, because the goods of ship shipment is different, require that the suspender of crane goods handling is also different, such as silt, iron ore sand, coal etc. need grab bucket to carry out loading and unloading operation, and timber, coiled steel plate etc. bundle sundries needs suspension hook to carry out loading and unloading operation.The steel rope of the switching mechanism of existing crane grab from the assembly pulley be wrapped in after each leading sheave after reel rope stretching grab bucket, then passes through each leading sheave backrush cylinder, by pressing plate, steel rope is fixed on reel.If suspender is changed suspension hook to carry out operation, just need lay winding wire ropes again, this is a job of wasting time and energy, and have impact on the service efficiency of hoisting crane, adds shipping and delivery cost.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of multi purpose partal crane quick-replaceable suspension hook group is provided, achieves the quick-replaceable between grab bucket, suspension hook, improve the service efficiency of hoisting crane, reduce the labour intensity of staff.
According to technical scheme provided by the invention, described multi purpose partal crane quick-replaceable suspension hook group, comprises two piece of second connecting panel, arranges lifting beam with hook, lifting beam with hook installs suspension hook between the bottom of two piece of second connecting panel; It is characterized in that: between the top of described two piece of second connecting panel, connect two the 3rd bearing pins respectively, two the 3rd bearing pins connect the first connecting panel respectively, respectively by the second bearing pin, two swivel coupling lower connecting plates are installed on the top of the first connecting panel, the upper end of swivel coupling lower connecting plate is fixedly connected with bearing outside, bearing outside arranges axle on swivel coupling, swivel coupling arranges clutch shaft bearing between axle and bearing outside; On described swivel coupling, the upper end of axle is connected with carving to overlap by the first bearing pin, carves in cover to arrange and carves block, carve winding steel rope on block.
Further, the both ends of described lifting beam with hook are fixed by the first clamp.
Further, the both ends of described first bearing pin are fixed by the second clamp.
Further, the two ends of described 3rd bearing pin are fixed by the 3rd clamp.
Further, the both ends of described second bearing pin are fixed by the 4th clamp.
The present invention has the following advantages: (1) the present invention is simple and reliable for structure, easy to maintenance; (2) present invention achieves the quick-replaceable between grab bucket and suspension hook, improve the service efficiency of hoisting crane.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the lateral plan of Fig. 1.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Fig. 1 ~ Fig. 2: as described in multi purpose partal crane quick-replaceable suspension hook group comprise steel rope 1, carve block 2, carve axle 5 on cover 3, first bearing pin 4, swivel coupling, clutch shaft bearing 6, the 4th clamp 7, bearing outside 8, swivel coupling lower connecting plate 9, second bearing pin 10, first connecting panel 11, spacing sleeve 12, the 3rd bearing pin 13, second connecting panel 14, nut 15, second bearing 16, lifting beam with hook 17, first clamp 18, suspension hook 19, second clamp 20, the 3rd clamp 21 etc.
As shown in Figure 1 and Figure 2, the present invention includes two piece of second connecting panel 14, lifting beam with hook 17 is set between the bottom of two piece of second connecting panel 14, the both ends of lifting beam with hook 17 are fixed by the first clamp 18, lifting beam with hook 17 is installed suspension hook 19, the lower end of suspension hook 19 is hook-shaped, and the sheathed nut 15 in upper end of suspension hook 19, arranges the second bearing 16 between nut 15 and suspension hook 19; Two the 3rd bearing pins 13 are connected respectively between the top of described two piece of second connecting panel 14, the two ends of the 3rd bearing pin 13 are fixed by the 3rd clamp 21, sheathed spacing sleeve 12 on the 3rd bearing pin 13 two the 3rd bearing pins 13 connecting respectively the first connecting panel 11, first connecting panel 11 both sides; Respectively by the second bearing pin 10, two swivel coupling lower connecting plates 9 are installed on the top of described first connecting panel 11, the upper end of swivel coupling lower connecting plate 9 is fixedly connected with bearing outside 8, bearing outside 8 arranges axle 5 on swivel coupling, swivel coupling arranges clutch shaft bearing 6 between axle 5 and bearing outside 8; On described swivel coupling axle 5 upper end by the first bearing pin 4 with carve cover 3 and be connected, carve in cover 3 to arrange and carve block 2, carve winding steel rope 1 on block 2;
The both ends of described first bearing pin 4 are fixed by the second clamp 20, and the both ends of the second bearing pin 10 are fixed by the 4th clamp 7.
Working process of the present invention: after unloading grab bucket by the quick coupling of steel rope, by four of hoisting crane steel ropes, (wherein two is grab bucket hoist rope, two with grab bucket opening and closing steel rope) respectively with carving block 2(4), carve 3(4, cover) be fixed in suspension hook group, steel rope 1 fixing firm after can carry out suspension hook loading and unloading operation.When in operation; steel rope there will be torsion phenomenon; after steel rope reverses; can drive carve axle 5 axle 5 on swivel coupling on cover 3, swivel coupling axis centered by rotate; and suspension hook 19 can not be driven by force to rotate, so both release the twisting resistance of steel rope, protect steel rope; the suspension hook hanging weight can not be driven again by force to rotate, ensure that the safe reliability of suspension hook operation.
