As shown in figure 12, described subframe 11 tops have fixed cover, have the skewed slot for fixing front leg strut 19 and rear support leg 21 in the time that front leg strut 19, rear support leg 21 fold in this fixed cover.
Thus, the pulling type lorry-mounted crane of the present embodiment has following function:
One, hoisting function:
1, dead work:
Main car is pulled trailer to work-yard, caterpillar wheel 20 is transferred to landing, front leg strut 19 and rear support leg 21 are turn to ground from subframe 11, insert bearing pin, start power system 9, control 22 liftings of rear support leg oil cylinder by hydraulic efficiency pressure system 8 and electric system 7, regulate the lifting of rear support leg oil cylinder 22 that the support foot plate of front leg strut 19 is effectively landed, now road wheel 10 is suspended from the ground (now adopting suspension hook 2 operations)
2, working process:
By the action of amplitude oil cylinder 16, the first telescopic oil cylinder 15, the second telescopic oil cylinder 13, drive the action of the first telescopic boom 14, the second telescopic boom 12, basic arm 17, can realize hoisting, declining of suspension hook 2, under the driving of swing type mechanism 18, hoisting device can do 360 ° of revolutions, thereby realizes the hoisting operation in certain scope of work;
Two, capture function.
1, dead work:
Main car is pulled trailer to work-yard, caterpillar wheel 20 is transferred to landing, front leg strut 19 and rear support leg 21 are turn to ground from subframe 11, insert bearing pin, start power system 9, control 22 liftings of rear support leg oil cylinder by hydraulic efficiency pressure system 8 and electric system 7, regulate the lifting of rear support leg oil cylinder 22, the support foot plate of front leg strut 19 is effectively landed, now road wheel 10 is suspended from the ground, combining action by arm moves to chassis of trailer 5 by arm head and lays robot device 1 place, take off suspension hook 2, bearing pin is through arm head suspension hook connecting bore and motor 23 head mounting holes, thereby robot device 1 is fixed on to arm head.
2, working process:
By the action of amplitude oil cylinder 16, the first telescopic oil cylinder 15, the second telescopic oil cylinder 13, drive the action of the first telescopic boom 14, the second telescopic boom 12, basic arm 17, can realize hoisting, declining of robot device 1, controlling ratchet 24 by hydraulic efficiency pressure system 8 and electric system 7 launches or shrinks, capture goods function thereby realize, by the rotation of motor 23 output shafts, can realize goods towards conversion, under the driving of swing type mechanism 18, hoisting device can do 360 ° of revolutions, realizes the crawl operation in certain scope of work.
Three, with car transportation function
Loop wheel machine assembly is bounced back to lowest order, place forward, supporting leg before and after packing up, lands the road wheel of chassis of trailer 5 10, rises caterpillar wheel 20, and trailer can be realized with car transportation function.
Four, from walking function
Transfer caterpillar wheel 20 and land, start power system 9, by driving the rub tyre surface of trailer road wheel 10 of assembly 6, thereby realize from walking function.
Pulling type lorry-mounted crane of the present invention is equipped with hoisting device, car load main body by self-powered source get on the bus, chassis of trailer 5 forms.Chassis of trailer 5 is for body supports and walking, gets on the bus for hoisting operation in self-powered source.
X-type subframe of the present invention has adopted light-weight design, has designed X-type, can alleviate the weight of subframe.
Supporting leg upset mode of the present invention adopts following design:
Front leg strut 19 has adopted weight-saving Truss Design, and weight is lighter, is convenient to upset.Single hinging-ear 25 on front leg strut 19 inserts the two hinge ears 28 on subframe 11, is then connected by torsion bar 26.When folding and unfolding supporting leg, can rotate torsion bar 26 by boosting-rod 27, thereby drive supporting leg rotation, transfer put in place after (as upper supporting leg is transferred as shown in constitution diagram), insert anchor shaft, as shown in upper supporting leg rounding state figure, when the lower rhabd of front leg strut 19 is inserted in the skewed slot of nylon jacket 29 on subframe completely, get final product fixed supporting leg.
Rear support leg 21 adopts same project organization with front leg strut 19, and upset mode is consistent.
Because single hinging-ear 25 forms angle with the mobile jib axis of front leg strut 19, two hinge ears 28 are also to form angle with subframe line of centers, so path of motion when supporting leg folding and unfolding is the conical surface, so, this kind of mode can make vehicle in the time that supporting leg draws in, take less space, thereby meet transportation request, can make again vehicle have larger supporting leg span in the time that supporting leg launches, thereby the operational capability of lifting vehicle.
As shown in the figure, front leg strut 19 line of centerss and supporting leg single hinging-ear 25 line of centerss form angle, and the two hinge of subframe fixed supporting leg line of centers and subframe ear 28 line of centerss form angle, therefore, front leg strut 19 can be around the rotation of supporting leg rotation centerline, and its path of motion is the conical surface, i.e. dash area shown in Figure 13.
Crawl operation of the present invention and hoisting operation pattern handoff procedure are: capture operation and hoisting operation pattern switching mechanism and be made up of bearing pin 30, suspension hook 2, manipulator assembly 1.On flexible arm head 31, leave mounting hole, in the time of hoisting operation, suspension hook 2 is connected to arm head by bearing pin 30, can drive hoisting, declining of suspension hook by boom arm sections resultant motion, thereby complete hoisting operation.Capture when operation can be by manipulator assembly 1, be connected to arm head by bearing pin 30, by the action of ratchet on boom arm sections resultant motion and robot device, can complete the actions such as goods captures, turns to.
The content that above-described embodiment is illustrated should be understood to these embodiment only for being illustrated more clearly in the present invention, limit the scope of the invention and be not used in, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the amendment of the various equivalent form of values of the present invention.
