Description

[Detailed description of the invention] (Field of industrial application) The present invention is a device for tightening containers loaded onto railway cars so that they do not move on the train. The present invention relates to an improved attachment device for container fasteners.

(Conventional technology) When loading a conventional container onto a railway vehicle,
As shown in Fig. 7, in order to prevent the container 1 from moving on the floor surface 3 of the vehicle due to vibrations caused by the running of the vehicle 2, a protrusion 4 is installed upward from the floor of the vehicle to prevent the container 1 from being loaded. The container 1 is provided with holes 5 at its four corners into which the projections fit, and the container 1 is inserted into the vehicle 2.
It is tightened (fixed) on the floor. Therefore, the protrusions planted from the floor of the vehicle 2 are planted according to the dimensions of the containers, but if it is necessary to load containers of different sizes, in that case, the protrusions planted can be turned up and down as needed to fit different types of containers. In that case, generally a rotating shaft 7 is provided on the edge 6 of the floor 3 of the vehicle 2, as shown in FIG. . If it is necessary to provide a protrusion, the container fastener 8 is placed on the floor of the vehicle and the protrusion is planted (A and C in Fig. 8); when the protrusion is not required, The container fastener 8 rotates around the rotation shaft 7 and falls downward, so that the floor surface of the vehicle becomes flat (B in FIG. 8).

(Problem to be solved by the invention) In this case, if the rotation axis 7 is provided above the floor surface 3 so that the center of rotation of the tightening tool 8 is above the floor surface 3, the tightening tool 8 can be moved below the floor surface 3. When the container 1 is positioned in
When the tightening device 8 corresponding to the
The rotating shaft 7 and the tightening device 8 remaining on the top will get in the way of the forklift when loading and unloading the container 1. For this reason, the rotation axis 7 cannot be provided above the vehicle floor 3, and when the container fastener 8 is rotated downward and stored under the floor of the vehicle, the rotation axis 7 cannot be installed above the vehicle floor 3. There is also a restriction that the extending arm 8a of the container fastener cannot protrude above the vehicle floor surface. Therefore, the state in which the container fastener 8 is placed on the floor of the vehicle and the protrusion is installed is as shown in FIG. 9, and when the container fastener 8 is rotated downward and stored under the floor. , the state will be as shown in FIG.

In this state, the protrusion 4 of the container fastener 8 hits the underframe 9 of the vehicle 2, and the container fastener 8, which should normally be rotated by about 3/4 of a turn and stored under the floor, does not rotate sufficiently and ends up in the middle. It stops. If this happens, the container fastener 8 will protrude from the specified vehicle width (vehicle limit) L, which will impede driving. To avoid this, cut out the lower part of the underframe 9 of the floor 3 of the vehicle 2 with a notch 9 as shown in the figure.
There are cases where it is necessary to make a notch. However, if the notch 9a cannot be made due to the shape or strength of the vehicle 2, the container fastener 8 can be attached to the underframe 9.
However, due to the hole 5 of the container 1, if such a movement is not possible, the container fastener 8 cannot be attached and the container cannot be loaded. There was a problem in that there were restrictions on the number of containers that could be used, which resulted in vehicles with poor operating efficiency. In addition, if it is absolutely necessary to install the container fastener 8, even if it is somewhat inconvenient when loading the container,
There was a problem in that the rotation shaft 7 had to be higher than the floor surface 3 of the vehicle.

In the present invention, the container fastener 8 rotates and falls.
When stored under the floor of the vehicle 2, the arm 8a of the tightening tool 8 can rotate without coming into contact with the underframe 9, and the vehicle limit is not affected. To provide a mounting device for a container fastener 8 in which an arm 8a of the fastener 8 does not protrude and a cutout 9a does not need to be provided in a lower part of an underframe 9.

(Means for Solving the Problems) The present invention, as a means for solving the above problems, rotates the container fastener around a rotation axis provided at the edge of the floor of the vehicle. Accordingly, in a vehicle in which the container fastening device is installed on and retracted from the floor of the vehicle, the pivot shaft is provided on the edge of the vehicle, and a second pivot is provided above the pivot shaft toward the vehicle side. A movable shaft is provided, a mounting arm of the container fastener is pivotally attached to the second rotary shaft, and a link whose both ends are rotatably rotatably mounted by the both rotary shafts is provided between the two rotary shafts. It is an intervention.

(Function) By doing this, the radius of rotation of the rotating part can be shortened compared to the conventional container tightening device in which the container tightening device is attached to the floor of the vehicle by a single rotating shaft. I can do it. In addition, by using the link, the installation position of the container fastener can be set with a certain degree of freedom when the container fastener is placed on the floor of the vehicle or stored under the floor of the vehicle. . As a result, when the container fastener is rotated and stored under the floor, it can be kept in a state in which it does not collide with the underframe, does not interfere with the vehicle limits, and does not protrude above the floor of the vehicle.

(Example) An example of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, a floor 10 of a railway vehicle for container transportation consists of an underframe 11 and a cross beam 12. A bracket 13 is provided laterally protruding from the edge of the floor, that is, the edge of the underframe 11, and supports a pivot shaft 14 at its tip. One pin hole 15b of the link 15 is rotatably attached to the rotation shaft 14, and the other pin hole 15a of the link 15 is connected to the second rotation shaft 1 to the mounting arm 17 of the container fastener 16.
8, it is rotatably attached to the shaft.

In the state shown in FIGS. 1 to 3, the container fastener 16 is placed on the floor of the vehicle and protrudes, and in the state shown in FIG. 4, it is rotated downward and buried in the floor of the vehicle. .

A stopper 19 is attached to the link 15 to limit the rotation angle between the attachment arm 17 of the container fastening tool 16 and the link 15. In other words, the container fastener 16 and the link 15 are allowed to rotate only 1/4 of a rotation relative to each other, and the link 15 is also allowed to rotate only about 1/2 of a rotation relative to the underframe 11 around the rotation axis 14. installed. If the container fastener 16 is thereby rotated, the link 15 will rotate within an angle range smaller than about 1/4 turn.
It rotates following the movement of the container fastener 16.
By newly providing the second rotation shaft 18 above the rotation shaft 14 on the vehicle 2 side, the lower part of the underframe 11 can be rotated without interfering with the container fastener 16. .

In this way, the link 15 and the container fastener 16
rotation around the second rotation axis 18 and the link 15
The rotation of the container and the underframe 11 around the rotation axis 14 is appropriately regulated by a stopper, and the placement position of the container fastener on the floor and the posture when stored under the floor are adjusted to suit the conditions of the case. Can be configured.

Next, the process of rotating the container fastening tool 16 from the state where the container fastening tool 16 is placed on the underframe 11 and storing it under the floor 10 of the vehicle will be described with reference to FIG. To do this, the container fastener 16 is lifted upward and rotated from the state shown in FIG.
The container fastener 16 rotates about 1/4 turn around , and the mounting arm 17 of the container fastener 16 comes into contact with the side surface 19a of the stopper 19 of the link 15 (FIG. 5a). Thereafter, the container fastening tool 16 and the link 15 rotate together around the rotating shaft 14 (FIG. 5b), and the container fastening tool 16 and the link 15 rotate about 1/2 and rotate to the fourth position. It is stored under the floor of the vehicle in the position shown in the figure. In this case, the container fastener 16 will not come into contact with the underframe 11, will not protrude from the vehicle limit L, and will not protrude above the floor surface 10 of the underframe 11.

Next, the process of placing the container fastener 16 on the underframe 11 from the storage position under the floor will be described with reference to FIG. When attempting to lift the container fastener 16 upward from the state shown in FIG. Mounting arm 17
comes into contact with the horizontal surface 19b of the stopper 19 of the link 15 (FIG. 6a). Thereafter, the container fastener 6 and the link 15 rotate together around the rotation shaft 14 (FIG. 6b), and the container fastener 16 and the link 15 rotate by about 1/2, as shown in FIG. The container fastener 16 is placed on the floor of the vehicle.

(Effects of the invention) Since the present invention has the above-described structure and function, the container tightening device is rotated around a rotation axis provided at the edge of the floor of the vehicle and stored under the floor. In this case, the container can be stored without any protruding objects protruding from the top surface of the underframe (vehicle floor surface), and without the container fasteners coming into contact with the underframe. Therefore, there is no need to cut out the underframe, and there is no problem with vehicle limits. As a result, the container fastener can be placed at any position on the floor of the vehicle without being limited by the width of the lower part of the underframe 9, and any container can be loaded. Vehicles with high operational efficiency can be provided.
