The specific embodiment
As shown in the cutaway view of an embodiment of anti-overturn device of container face crane as of the present invention in Fig. 1, anti-overturn device of container face crane of the present invention comprises: be arranged on the first support 13 and the second support 14 between vehicle frame and the back axle of suspension transferring machine, sensor 10, controller, described vehicle frame and back axle are hinged by described the first support and described the second support, described the second support comprises and moves up and down pair, in the time that suspension transferring machine has the danger of toppling, vehicle frame rear portion can upwarp, described back axle can be around the hinge-point rotation of described the first support under the effect of deadweight, describedly move up and down secondary interelement and occur relatively moving, described in described sensor detects, move up and down secondary movable signal and send to described controller, described controller control suspension transferring machine jib stops stretching out and promoting.
Particularly, as shown in Figure 2, be welded with the first bearing 13c on vehicle frame, the first bearing 13c is a pair of otic placode, is welded with connecting panel 13e on back axle, and connecting panel 13e is between the first bearing 13c, and it is hinged to pass through the first bearing pin 13a.Between the first bearing pin 13a and connecting panel 13e, be provided with the first oscillating bearing 13b.
The second support 14 also comprises: be fixed on the second bearing 1 on vehicle frame, the described pair that moves up and down comprises core body 2, back axle casing 3, described the second bearing 1 is hinged by the second bearing pin 5 with described core body 2, described back axle casing 3 is fixed on described back axle, described in described core body position in back axle casing, and can move up and down.
Particularly, as shown in Figure 3, the second bearing 1 of the present invention is for being welded on a pair of otic placode on vehicle frame, and back axle casing 3 of the present invention is welded on back axle 11, the cross-sectional plane of back axle casing 3 is sealing rectangle (as shown in Figure 4), the open-top of back axle casing 3.The top of core body 2 is placed between a pair of otic placode, and hinged with a pair of otic placode by the second bearing pin 5, insert in back axle casing 3 bottom of core body 2, in the pair of side plates of back axle casing 3, be respectively arranged with through hole 30a, 30b, the bottom of core body 2 is provided with the through hole corresponding with through hole 30a, 30b 20, one end of the 3rd bearing pin 7 is passed through hole 30a, through hole 20, through hole 30b successively, thereby the bottom of core body 2 is connected with back axle casing 3.One end of the 3rd bearing pin 7 is set with locating piece 7b, locating piece 7b is positioned at through hole 30b, and the other end of the 3rd bearing pin 7 has termination 7a, and termination 7a is positioned at through hole 30a, the height of locating piece 7b and termination 7a and/or length are greater than through hole 20, thereby the 3rd bearing pin 7 can not deviate from from through hole 20.
Said in the present invention " length of locating piece 7b and termination 7a " refers to: in the horizontal surface of the axis by the 3rd bearing pin 7, and in the direction axial perpendicular to the 3rd bearing pin, the size of locating piece 7b and termination 7a.
Wherein, the height of through hole 30a, 30b is greater than respectively the height of termination 7a and locating piece 7b.
The present invention also comprises the sensor 10 moving for detecting core body 2, be arranged on (as shown in Figure 4) on back axle casing 3, and be connected with control system (not shown), in the time that container face crane will topple, core body 2 moves up, the core body movable signal detecting is passed to control system by sensor 10, and the jib of control system control container face crane stops extending and hoisting, thereby plays the effect that prevents that front swing-machine from toppling.
Concrete, in the time that container face crane is normally worked lift heavy, the termination 7a of the 3rd bearing pin 7 contacts with the bottom of through hole 30a, 30b respectively with locating piece 7b.In the time that container face crane topples, vehicle frame rear portion will be upturned, drive the first bearing 13c, the second bearing 1 to move up, because core body can be up and down in back axle casing, back axle can rotate around the 3rd bearing pin under own wt effect, the relative back axle casing of core body 2 is moved up, sensor 10 detects when the movement of core body 2 reaches predetermined value, just this movable signal is passed to control system, the jib of control system control container face crane stops extending and hoisting, thereby prevents toppling of front swing-machine.
Due to inertia or tilting moment excessive, although the jib of front swing-machine has stopped extending and hoisting, vehicle frame likely continues to topple forward, so just, can drive core body 2 to continue to move up, core body 2 drives the 3rd bearing pin 7 to move up in through hole 30a, 30b, when the termination 7a that moves to the 3rd bearing pin 7 when the 3rd bearing pin 7 contacts with the top of through hole 30a, 30b respectively with locating piece 7b, the weight of whole back axle 11 has been added to vehicle frame rear portion, has prevented the generation that vehicle frame further topples.
For the termination 7a and the locating piece 7b that prevent the 3rd bearing pin 7 clash into the top of through hole 30a, 30b respectively, the present invention is provided with collision mat 6 at the top of through hole 30a, 30b.
As shown in Figure 4, through hole 30a, the 30b in the present invention is rectangle, and termination 7a and locating piece 7b are also rectangle; Through hole 20 is circular, and the 3rd bearing pin 7 is also circular.Through hole 30a, 30b top can also be circular (as shown in Fig. 4 a) or other shape, and termination 7a and locating piece 7b can be also circular (as shown in Fig. 4 a), wedge shape or other shape.
Bottom and back axle casing 3 inner bottom parts for fear of core body 2 clash into, and the present invention is provided with collision mat 8 at back axle casing 3 inner bottom parts.
In addition, ride comfort when guaranteeing that container face crane travels on rugged road surface, and container face crane turn time alerting ability, the present invention is provided with second joint bearing 4 between the top of core body 2 and the second bearing pin 5, and the top of core body 2 is sleeved on the second bearing pin 5 by second joint bearing 4.
As shown in Figure 6, in the present embodiment, the middle part diameter of the 3rd bearing pin 7 is greater than both ends diameter; Stop block 7c for the middle part of backstop the 3rd bearing pin is installed in through hole 30a, 30b on back axle casing 3, stop block 7c can be fixed on any position in through hole 30a, 30b, to dwindle the A/F of through hole 30a, 30b, make the A/F of through hole 30a, 30b be less than the middle part diameter of the 3rd bearing pin, to prevent that the 3rd bearing pin 7 from deviating from from through hole 20.
Other structure of the present embodiment is identical with embodiment 1, is not repeated at this.
Although above the present invention is explained in detail; but the invention is not restricted to this; those skilled in the art can principle according to the present invention modify, and therefore, all various modifications of carrying out according to principle of the present invention all should be understood to fall into protection scope of the present invention.
