Specific embodiment
Below in conjunction with attached drawing and the embodiment provided, the present invention is further illustrated.
As shown in Fig. 1 to Fig. 7, Figure 15, Figure 18 and Figure 19, a kind of anti-tipping dumper, including compartment 1, rack 2 and act
Rise control mechanism 3；The rear portion in the compartment 1 is hinged in rack 2；The lifting control system 3 include fuel tank 4, hydraulic pump 5,
Hand-operated direction valve 6, elevating ram 7；The oil inlet of the hydraulic pump 5 is connected to fuel tank 4, the oil outlet of hydraulic pump 5 with change manually
It is connected to the oil inlet P mouth of valve 6；The piston rod 7-1 of the elevating ram 7 is hinged on the middle part or front in compartment 1, elevating ram
7 cylinder body 7-2 is hinged in rack 2；It further include anti-tilting apparatus 8；The anti-tilting apparatus 8 include stopper 9, mandril 10,
Return of stroke valve installing mechanism 11 and return of stroke valve 12；As shown in Figure 3 and Figure 4, the stopper 9 is fixedly connected on rack 2
On；As shown in Figure 7 and Figure 8, the return of stroke valve installing mechanism 11 includes weight element 13 and mounting plate 14；The counterweight member
The top of part 13 has circular hole 13-1 and weight element 13 is hinged with rack 2 at circular hole 13-1, and weight element 13 can be around rack 2
Rotation, the mounting plate 14 are fixedly connected on weight element 13；Weight element 13 uses the biggish material of specific gravity, such as can be with
Using steel or copper, the material lighter using specific gravity of mounting plate 14, such as aluminium or plastic part can be used, circular hole 13-1 setting is being matched
Between the center of gravity of weight element 13 and the center of gravity of mounting plate 14, return of stroke valve installing mechanism 11 need to meet following relational expressions: G1*L1
=G2*L2, wherein G1 is the weight of mounting plate 14, and L1 is the center of gravity of mounting plate 14 to the horizontal distance of circular hole 13-1, and G2 is counterweight
The weight of element 13, L2 is the center of gravity of weight element 13 to the horizontal distance of circular hole 13-1, due to return of stroke valve installing mechanism
11 weight element 13 is hinged with rack 2 at circular hole 13-1, and return of stroke valve installing mechanism 11 meets above-mentioned relation formula, because
This trip reversal valve installing mechanism 11 can be swung around the hinge of itself and rack 2, and return of stroke valve installing mechanism 11 is in gravity
Under the action of so that mounting plate 14 is remained at the horizontality in Fig. 7, i.e., rack when dumper goes up a slope can in heeling condition,
But return of stroke valve installing mechanism 11 can rotate relative to rack 2 under gravity and mounting plate 14 is made to remain at level
State.As shown in figure 14, hinge of the weight element 13 of the return of stroke valve installing mechanism 11 around weight element 13 and rack 2
Weight element 13 offsets with stopper 9 when being rocked to set angle；Set angle therein is to be computed and dumper can be caused to send out
The angle of gradient of the upward slope road of raw overthrow accident.As shown in figure 12, at this moment dumper on it can generate the up gradient road tumbled,
At this moment the angle of gradient of upward slope road is set angle.At this moment the compartment 1 of dumper not yet lifts the thing that will not also tumble
Therefore as shown in figure 15, overthrow accident will occur when lifting compartment 1 on this up gradient road when dumper to certain angle.
The mandril 10 is fixedly connected on the rear on compartment 1 and being located at the hinge of compartment 1 and rack 2, and the return of stroke valve 12 is solid
Surely it is connected on the mounting plate 14 of return of stroke valve installing mechanism 11；The compartment 1 drives mandril 10 around compartment 1 and rack 2
When hinge rotates to set angle, mandril 10 can be made to meet the idler wheel 12-1 of return of stroke valve 12 and drive return of stroke valve 12
Spool is mobile；As shown in figure 18, A mouthfuls of execution mouth of the oil inlet P mouth of the return of stroke valve 12 and hand-operated direction valve 6 are connected to,
A mouthfuls of mouth of execution of return of stroke valve 12 are connected to the rodless cavity of elevating ram 7, the oil return inlet T mouth of return of stroke valve 12 and manually
The oil return inlet T mouth of reversal valve 6 is connected to fuel tank 4.Return of stroke valve 12 is a kind of servomotor driven change valve, the type of return of stroke valve 12
Number it can be 23C-25B or 23C-25BH.Under normal circumstances, the oil inlet P mouth of return of stroke valve 12 communicates for mouth A mouthfuls with execution,
After mandril 10 meets the idler wheel 12-1 of return of stroke valve 12 and drives the spool movement of return of stroke valve 12, return of stroke valve 12
Oil return inlet T mouth with execute mouth A mouthfuls communicate.
As shown in figure 18, the oil inlet of the hydraulic pump 5 to the oily channel of fuel tank 4 is equipped with filter 15.
The oil outlet of the hydraulic pump 5 to the oily channel of fuel tank 4 is equipped with safety valve 16.
As shown in Figs. 8 to 11, the weight element 13 of the return of stroke valve installing mechanism 11 and the rear portion in compartment 1 pass through
Pin shaft 17 is coaxially hinged in rack 2.Only weight element 13 and compartment 1 need to can be made hinged using a pin shaft 17 in this way
In rack 2, structure is very simple.
Working principle of the present invention is as follows: self-unloading is carried out when dumper is no on the up gradient road for can occur overthrow accident
When operation, as shown in Figure 12, Figure 13 and Figure 14, rack 2 is in heeling condition, and return of stroke valve installing mechanism 11 is in the work of gravity
Horizontality is remained at lower installation board 14, as shown in figure 14, the at this moment weight element 13 of return of stroke valve installing mechanism 11
It offsets with the stopper 9 for being fixedly connected on rack 2, return of stroke valve installing mechanism 11 cannot be rotated clockwise with respect to rack 2 again；
As shown in Figure 15 to Figure 17, Figure 18, when dumper need to carry out self-unloading operation, the handle of hand-operated direction valve 6 is operated, makes to change manually
To valve 6 oil inlet P mouth with execute mouth A mouthful and communicate, due under normal circumstances, oil inlet P mouth and the execution of return of stroke valve 12
A mouthfuls of mouth communicates, therefore the pressure oil in hydraulic pump 5 can enter elevating ram 7 through return of stroke valve 12 again through hand-operated direction valve 6
Rodless cavity, pressure oil push the piston rod 7-1 of elevating ram 7 to stretch out.It drives compartment 1 to rotate around vehicle frame 2 by piston rod 7-1, makes
It lifts to carry out self-unloading operation in compartment 1.When elevating ram 7 drives compartment 1 to rotate around the hinge of itself and rack 2 to can cause to incline
When turning over the angle of accident, at this moment compartment 1 drives mandril 10 to rotate to set angle around the hinge of compartment 1 and rack 2, and mandril 10 touches
To the idler wheel 12-1 of return of stroke valve 12, since return of stroke valve installing mechanism 11 cannot the opposite rotation clockwise of rack 2 again at this time
Turn, mandril 10 will not make return of stroke valve installing mechanism 11 with respect to 2 up time of rack when pushing the idler wheel 12-1 of return of stroke valve 12
Needle rotation, therefore the spool of return of stroke valve 12 can be pushed mobile, make mouth A mouthfuls of oil return inlet T mouth and the execution of return of stroke valve 12
It communicates, the pressure oil of the rodless cavity of elevating ram 7 can return to fuel tank 4, the i.e. rodless cavity of elevating ram 7 through return of stroke valve 12 not
There is pressure oil again, the gravity lower piston rod 7-1 in compartment 1 is retracted, and drives compartment 1 reversed around vehicle frame 2 by piston rod 7-1
Rotation makes compartment 1 fall, the overthrow accident of dumper will not thus occur.
