Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is that A of the present invention is to scheme drawing.
The specific embodiment
Embodiment during following the present invention incites somebody to action by reference to the accompanying drawings is further described:
As Fig. 1 ~ shown in Figure 2, the present invention includes operator's station 1, derricking gear 4, pulley mechanism 6, cable 8, base seat support 10, take-up basket 12, hook 13 and grab bucket 15, described base seat support 10 is positioned at the transfer crane top, operator's station 1 and derricking gear 4 are positioned on the base seat support 10, pulley mechanism 6 is positioned at base seat support 10 head upper surfaces, hook 13 is connected pulley mechanism 6 lower ends by steel rope 5, and described take-up basket 12 is positioned on the cable 8; Described cable 8 upper ends are connected in the operator's station 1, and the lower end is connected in the grab bucket 15; Described grab bucket 15 is positioned at hook 13 lower ends.
Described operator's station 1 is provided with operating handle 11 and plugs and sockets 9, and the upper end of cable 8 is connected with plugs and sockets 9; Described derricking gear 4 is provided with steel rope 5, and derricking gear 4 is connected with pulley mechanism 6 by steel rope 5; Described hook 13 is connected pulley mechanism 6 lower ends by steel rope 5; Described pulley mechanism 6 and derricking gear 4 are on the same straight line; Described base seat support 10 is provided with aisle 2, and 2 both sides, aisle are provided with guardrail 3; Also be provided with cable hanger 7 on base seat support 10 lower planes; Described cable 8 is provided with clip 8-1; Described grab bucket 15 comprises upper cover 15-1, hydraulic pressure assembly 15-2, hydraulic ram 15-3, upper shell 15-4, lower shell 15-5 and bucket body 15-6, and described upper cover 15-1 is positioned at upper shell 15-4 upper end, and lower shell 15-5 is positioned at upper shell 15-4 lower end; Described hydraulic pressure assembly 15-2 is positioned at upper shell 15-4 and lower shell 15-5 inside, and hydraulic ram 15-3 one end connects upper shell 15-4, and the other end connects bucket body 15-6, connects by hydraulic pipe between hydraulic ram 15-3 and the hydraulic pressure assembly 15-2.Described quick coupling 14 is positioned in the grab bucket 15, and the lower end of cable (8) connects quick coupling 14.
Working process of the present invention:
Before the transfer crane work, to carry out the erection work of cable 8 earlier.When mounted, the operator enters operator's station 1 and opens host power supply, and the steel rope 5 in derricking gear 4 reels is put down.On the described cable 8 clip 8-1 is arranged, staff on the ground is buckled in cable 8 on the steel rope 5 that puts down, and will grab bucket 15 hang over the hook 13 on, the lower end of cable 8 is connected in the quick coupling 14 of grab bucket.To rising, the cable 8 of will grabbing bucket takes transfer crane top to by steel rope 5.Be welded with cable hanger 7 on the described base seat support 10, the operator takes off cable 8 on the steel rope 5, and with cable 8 upper end connection plug sockets 9, the clip 8-1 on the cable 8 hangs on the cable hanger 7.Erection work this moment is finished, and grab bucket 15 can begin to grasp goods.When work, 15-3 stretches out and withdrawal by hydraulic pressure assembly 15-2 control hydraulic ram, stretch out and the withdrawal of hydraulic ram 15-3 drives closing up of bucket body 15-6 again and opens, can control the strength size that each bucket lobe grasps goods by the size of control hydraulic coupling, the alerting ability of grab bucket 15 is strengthened greatly.After finishing the work, the operator takes off cable 8, is buckled on the steel rope 5, and steel rope 5 is put down.The surface work personnel take off the cable 8 that lowers from steel rope 5, and the grab bucket 15 on hook 13 is taken off, and then cable 8 lower ends are taken off from quick coupling 14.The surface work personnel should keep properly cable 8 and the grab bucket of taking off 15, and the operator receives in the reel steel rope 5 and the Shutdown Hosts power supply.
