Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a container trailer connected to a tractor and capable of dumping up a container.
[0002]
[Prior art]
As shown in FIG. 4, the conventional container trailer T has a structure in which the container 11 is integrally attached to the frame 12, and the dump of the container trailer T is lifted by the tractor 14 attached to the frame 12 via the lift coupler 13. Performed by the arm 15.
[0003]
At this time, the rotation shaft 16 of the lift coupler 13 at the tip of the lift arm 15 rises while drawing an arc E having a radius r centering on the rotation shaft 17 of the lift arm 15.
[0004]
Therefore, when coming to rise pivot shaft 16 of the lift coupler 13 from position A to position B, it comes in dashed position by the arcuate movement container trailer T retreats from the solid line position by a distance L _1. When the rotation shaft 16 is at the more elevated to the position C, now come to dashed line position advances from the dashed line position by a distance L _2.
[0005]
[Problems to be solved by the invention]
In this way, the conventional container trailer T moves backward after moving back in the dump-up process. For this reason, there are the following problems.
[0006]
(1) is scheduled to retreat distance L ₁ of the container trailer T, because must be made to the dump up, is troublesome positioning of the container trailer T.
[0007]
(2) Since the container trailer T cannot be moved by applying a brake or the landing gear 18 cannot be used to maintain the attitude of the container trailer T horizontally, the container trailer T becomes unstable and falls. Or an excessive force may be applied to the lift arm 15 to break it.
[0008]
An object of this invention is to provide the container trailer which can solve such a conventional problem.
[0009]
[Means for Solving the Problems]
The present invention can solve the above problems by providing the following configuration.
[0010]
(1) A container trailer connected to a tractor, comprising a landing gear on the front side and a container having an outrigger jack on the rear side so that the container can be rear dumped via a dump hinge. A container dump-up mechanism is provided, and the dump-up mechanism is a hydraulic cylinder disposed in the center in the width direction of the frame and interposed between the frame and the container. container trailer, characterized in that it comprises a stabilizer that prevents swaying of containers on the left and right sides of the hydraulic cylinder there.
[0011]
[Action]
Since the container trailer according to the present invention is configured so that the container can be rear dumped on the frame and is dumped up by the dump up mechanism installed on the frame, the container trailer does not move as the container is dumped.
[0012]
[Reference example]
Reference Example 1 will be described below prior to the embodiment of the present invention.
[0013]
[ Reference Example 1]
FIG. 1 is a side view schematically showing a state in which a container trailer of a reference example is connected to a tractor, and FIG. 2 is a plan view of the container trailer in FIG.
[0014]
In the figure, T ₁ is a two-axis container trailer, and T ₂ is a two-axis tractor connected to the container trailer T ₁ via a coupler C.
[0015]
The container trailer T ₁ includes a container 1, a frame 3 in which the container trailer T ₁ is mounted so as to be capable of rear dumping via a dump hinge 2, and a multistage hydraulic cylinder 4 interposed between the frame 3 and the container 1.
[0016]
The hydraulic cylinder 4 has a lower end attached to the frame 3 by a rotating shaft 5 and an upper end attached to a bracket 7 of the container 1 by a rotating shaft 6.
[0017]
The container 1 is rear dumped with the front end pushed up by the force generated by the hydraulic cylinder 4.
[0018]
Although not shown, the frame 3 has a structure in which a floor plate is attached to a frame main body formed by connecting a main rail and a side rail with a cross member and an outrigger.
[0019]
The front side of the frame 3, the landing gear 8 (auxiliary leg) is attached for supporting the front portion of the container trailer T _1, the rear end, outrigger jack 9 for supporting the container 1 which is Riyadanpu at its lower side Is attached. The outrigger jack 9 is a support leg provided as necessary. In addition, 10a is an oil tank and 10b is a fuel tank.
[0020]
As described above, the container trailer T ₁ of this reference example has a configuration in which the container 1 is mounted on the frame 3 so as to be capable of rear dumping, and is dumped up by a hydraulic cylinder 4 interposed between the frame 3 and the container 1. Therefore, it does not move back and forth as the container 1 is dumped up.
[0021]
Therefore, the position to dump up container 1, i.e. it is easy to determine the position of the container trailer T _1.
[0022]
Further, by applying a brake to the container trailer T ₁ or using the landing gear 8, the container trailer T ₁ can be held horizontally so as not to move. As a result, or the container trailer T ₁ is overturned becomes unstable in the course of dump up container 1, it takes an excessive load on the hydraulic cylinder 4, which may no longer be or broken.
[0023]
Further, since the outrigger jack 9 effectively receives the load applied to the rear side of the frame 3 due to the dumping up of the container 1, it is possible to prevent the frame 3 from being inclined due to the dumping up.
[0024]
Next, an embodiment of the present invention will be described.
[0025]
[Example 1]
Container trailer shown in Figure 3 is an example in which a stabilizer S of preventing shaking of the left and right container 1 in the right and left sides of the hydraulic cylinder 4 in the container trailer T ₁ 2. The stabilizer S here is of the same type and type as the hydraulic cylinder 4.
[0026]
If the stabilizer S is used in this way, it is possible to prevent an excessive load from being applied to the hydraulic cylinder 4 even when the frame 3 is inclined when the container 1 is dumped up.
[0027]
【The invention's effect】
As described above, the container trailer according to the present invention is configured so that the container can be rear dumped on the frame and is dumped up by the dump up mechanism that is also installed on the frame, and does not move with the container dumping up. Since this is done, the following effects are produced.
[0028]
(1) Since it is not necessary to schedule the movement of the container trailer accompanying the dumping of the container, the positioning of the container trailer is facilitated.
[0029]
(2) Since the container trailer can be held horizontally so as not to move by using a brake or a landing gear, there is no possibility of the container trailer becoming unstable and falling over in the process of dumping the container. Further, for the same reason, an excessive load is applied to the hydraulic cylinder, and there is no possibility that it will break.
