The specific embodiment
With reference to accompanying drawing, will be described in detail the specific embodiment of the present utility model.
The excavator 7 that can turn round the multipurpose suspender that is equipped with of the present utility model, structure as shown in Figure 2, can comprise not shown motor, hydraulic system, equipment, part such as running gear and electrical control, make it have the basic function of excavator, described excavator is replaced by suspender 4 of the present utility model with the shovel of common excavator 3, between described suspender 4 and the forearm 2 at a, two points of b place is hinged, can adopt two parallel bearing pins and forearm 2 to be hinged, can realize that suspender 4 serves as that axle is rotated with the axis of rotation (bearing pin) that parallels with ground, thus can with facade that drawing parallels on swing up and down.The pin joint of this suspender can match with existing excavator.Certainly, this jointed shaft also can with ground at an angle.
The structure of described suspender 4 as shown in Figure 3, Figure 4, Fig. 3 is the front view of suspender 4, Fig. 4 is the vertical view of suspender 4, described suspender 4 comprises the connector 42 that is connected with forearm 2, connector 42 is hinged by bearing pin and forearm 2.
42 times turntable 43 can be installed at connector, the protruding rod pallet fork 44 that is used to pitch goods on the turntable 43.Described turntable 43 can with the perpendicular plane of drawing in (is the plane to call this face in the following text) carry out independent revolution, that is: with the perpendicular axle of described bearing pin be that axis of rotation rotates, thereby drive pallet fork 44 revolutions.According to different needs, described axis of rotation also can be other directions, such as: angled with described bearing pin.If do not need revolution, then can not establish turntable 43, directly protruding pallet fork 44 on connector 42 drives the motion of pallet fork 44 by the unitary rotation of suspender.
The revolution of described turntable 43 can be controlled by hydraulic system, so set up a hydraulic system on original excavator, perhaps utilizes original hydraulic system, increases corresponding component.As Fig. 2, Fig. 5, shown in Figure 7, the structure of hydraulic system is by the control pedal in the locomotive 51 (or handle) control reversal valve 52, the power oil 58 that makes input reversal valve 52 is connected in the hydraulic power unit 54 that is installed on the suspender through fluid pressure line 53, drives and control hydraulic power unit 54, hydraulic power unit 54 drives turntable 43 revolutions by its transmission mechanism, thus and then drive pallet fork 44 revolutions.
Described reversal valve 52 can be as Fig. 5, and bi-bit bi-pass reversal valve shown in Figure 7 also can adopt the control valve of other form, and the power oil 58 on it can be from hydraulic pump (not shown) supporting on the excavator.
The structure of described hydraulic power unit 54 can be existing any form.Below be preferred two kinds of structures:
First, as Fig. 5, shown in Figure 6, described hydraulic power unit 54 can be: the worm screw 55 that the hydraulic motor (not shown) that is connected with fluid pressure line 53 drives, described worm screw 55 is because the two-way function of bi-bit bi-pass reversal valve 52, so can carry out two-way rotation, as shown in Figure 6, worm screw 55 is meshed with worm gear 56, connect pallet fork 44 on worm gear 56 outputs, the rotation of described worm gear 56 can realize by the ball 57 that is arranged at worm gear 56 inboards among Fig. 6, also can rotating shaft be set in the axle center of worm gear.
Second, as Fig. 7, shown in Figure 8, hydraulic power unit 54 can be: the oil cylinder 61 that is connected with fluid pressure line 53 is because the two-way function of bi-bit bi-pass reversal valve 52, so can move back and forth, as shown in Figure 8, oil cylinder 61 connects tooth bar 62, drives tooth bar 62 and moves back and forth, rack and pinion 63 is meshed, handsetting gear 63 serves as that axle rotates with bearing pin 64, connects pallet fork 44 on the output of gear 63, rotates thereby drive pallet fork 44.Described pallet fork 44 can link together by bearing pin 64 and gear 63 simultaneously.
Above structure can realize the full circle swinging or half revolution of pallet fork 44.
The form of described pallet fork 44 can be according to the different structure of kind design of the goods that will load and unload, and such as directly pitching as shown in drawings, described straight fork can be single or multiple.Described pallet fork also can be hook-shaped.
The excavator that can turn round the multipurpose suspender that is equipped with of the present utility model, because the excavator walking is flexibly, body can turn round, and big arm, forearm stretch flexibly, suspender of the present invention in addition can planar turn round, thereby makes its flexibility that works together bigger, and efficient is higher.
In implementation process, be preferably applied to following two kinds of operating modes:
The scroll wire rod in shipment, unload ship time, as shown in Figure 9, can utilize suspender of the present utility model belowdecks, pitch center with pallet fork belowdecks into coiled material, carry out work.
Equally, the scroll wire rod as shown in figure 10, can utilize suspender of the present utility model in entrucking, when unloading, and pitches center into coiled material with pallet fork, carries out work.
Equally, this suspender also can hang the kinds of goods of lifting rope.
