The housing portion 600BR is a member that supports the arm cylinder unit 220 and the arm rod 230 of the movable leg portion 200BR. The housing parts 600FL, 600FR, 600BL and 600BR are fixed to the floor inside the container body 10 .

The housing portion 600FR has the same structure as the housing portion 600FL, and corresponds to the housing portion 600FL that is reversed in the left-right direction with respect to the center plane C1 in the width direction shown in FIG. 3 and then slightly shifted forward. . The housing portion 600BL has the same configuration as the housing portion 600FL, and is symmetrical with the housing portion 600FL with respect to the longitudinal center plane C2 shown in FIG. The housing portion 600BR has the same structure as the housing portion 600BL, and corresponds to the housing portion 600BL that is reversed in the left-right direction with respect to the center plane C1 in the width direction shown in FIG. 3 and then slightly shifted rearward. . Thus, housing portions 600FR, 600BL, and 600BR have a common configuration with housing portion 600FL. Therefore, in the following, the housing portion 600FL will be mainly described, and with respect to the housing portions 600FR, 600BL, and 600BR, the same reference numerals will be given to the structures common to the housing portion 600FL, and the description thereof will be omitted as appropriate.

As shown in FIGS. 4 and 5, the housing portion 600FL includes a housing body 610, a receiving portion 620 (left receiving portion in the present invention), an upper wheel body 630 (upper left guide rotating member in the present invention), and a lower wheel. It has a body 640 (left lower guide rotating member according to the present invention) and spring units 650 and 660 (left elastic members according to the present invention).

The housing body 610 is box-shaped and has a rectangular left half 611 elongated in the horizontal direction and a rectangular cylindrical right half 612 projecting rightward from the right end of the left half 611 . is a member of The internal space of the housing main body 610 consists of the internal space of the left half portion 611 and the internal space of the right half portion 612 . The internal space of the left half portion 611 is considerably larger than the arm cylinder unit 220 in the longitudinal direction. The internal space of the right half portion 612 is slightly larger than the arm cylinder unit 220 in the front-rear direction. As a result, a space in which the arm cylinder unit 220 can move horizontally in the front-to-rear direction within the housing body 610 is secured within the range indicated by the arrow d1 in FIG.

The upper wheel body 630 is rotatably supported on the upper part of the left half part 611 by supporting the shaft part 632 on the pivot part 250 . Further, the upper wheel body 630 rotates as the arm cylinder unit 220 moves in the arm extension/retraction direction while restricting the upward movement of the arm cylinder unit 220 by coming into contact with the upper surface 221a of the unit main body 221. . Accordingly, the upper wheel body 630 serves to guide the movement of the arm cylinder unit 220 in the arm extension/retraction direction. Moreover, the upper wheel body 630 does not restrict the movement of the arm cylinder unit 220 in the direction crossing the arm extension/retraction direction. That is, upper wheel body 630 restricts upward movement of arm cylinder unit 220 while allowing horizontal movement of arm cylinder unit 220 .

The lower wheel body 640 has a wheel body 641 and a shaft portion 642 serving as a rotation axis thereof. The wheel body 641 is a cylindrical member along the front-rear direction. The wheel body 641 is slightly shorter in the front-rear direction than the internal space of the left half portion 611 . The shaft portion 642 protrudes forward from the front end of the wheel body 641 and protrudes rearward from the rear end of the wheel body 641 . The shaft portion 642 is supported by the shaft support portion 260 . The pivotal support portion 260 is provided at the lower portions of the front wall portion and the rear wall portion of the left half portion 611 (the lower left restricting portion referred to in the present invention), both of which are provided near the left end of the left half portion 611 . The lower wheel body 640 is rotatably supported on the lower portion of the left half portion 611 by supporting the shaft portion 642 on the pivot portion 260 . Further, the lower wheel body 640 rotates as the arm cylinder unit 220 moves in the arm extension/retraction direction while restricting the downward movement of the arm cylinder unit 220 by coming into contact with the lower surface 221b of the unit main body 221. . Accordingly, the lower wheel body 640 serves to guide the movement of the arm cylinder unit 220 in the arm extension/retraction direction. Further, the lower wheel body 640 does not restrict the movement of the arm cylinder unit 220 in the direction crossing the arm extension/retraction direction. That is, the lower wheel body 640 restricts the downward movement of the arm cylinder unit 220 while allowing the horizontal movement of the arm cylinder unit 220 .

The spring unit 650 has a spring portion 651 and a contact portion 652 . The spring portion 651 is an elastic member extending in the front-rear direction and capable of extending and contracting in the front-rear direction. The front end portion of the spring portion 651 is fixed to the front wall portion of the left half portion 611 slightly to the right of the upper wheel body 630 in the left-right direction and in the center of the left half portion 611 in the up-down direction. The contact portion 652 is a member that contacts the arm cylinder unit 220 and is fixed to the rear end portion of the spring portion 651 . A limit switch is provided in the spring unit 650 . This limit switch operates when the spring portion 651 is contracted to the limit, and transmits an alert signal to the control portion 110 .

[Container behavior]
In the above configuration, when arm cylinder unit 220 and arm rod 230 are extended under the control of control section 110 , wheel unit 240 provided at the right end of arm rod 230 contacts the right wall section of receiving section 620 . As a result, the arm cylinder unit 220 and the arm rod 230 extend while the arm rod 230 is supported by the receiving portion 620, so the arm cylinder unit 220 moves leftward along the arm extension/retraction direction. Along with this, the jack leg 210 fixed to the left end of the arm cylinder unit 220 moves in a direction projecting leftward from the container body 10 . Further, when arm cylinder unit 220 and arm rod 230 contract, wheel unit 240 comes into contact with the left wall portion of receiving portion 620 . As a result, the arm cylinder unit 220 and the arm rod 230 are contracted while the arm rod 230 is supported by the receiving portion 620, so that the arm cylinder unit 220 moves in the direction of retraction into the container body 10 along the arm extension/contraction direction. Along with this, the jack leg 210 fixed to the left end of the arm cylinder unit 220 moves in the direction in which it is pulled into the container body 10 . In this way, the movable leg portion 200FL can be moved from the container body 10 by moving the arm cylinder unit 220 as described above while the jack leg portion 210 has a length that allows it to move in and out of the container body 10 through the entrance 11b. The jack legs 210 can selectively assume a state of being extended to the outside and a state of being retracted into the container body 10.例文帳に追加

In the state shown in FIG. 1 in which the container 1 is loaded on the vehicle 6, the jack legs 210 of both the front leg pair 20 and the rear leg pair 30 are retracted, and the jack legs 210 are retracted into the container body 10. Contained. Also, the doors of the entrances 11b, 11c, 12b and 12c are closed. In order to shift from this state to the state shown in FIG. 2 in which the container 1 is unloaded from the vehicle 6 onto the ground, the container 1 is operated as follows. First, the doors of the entrances 11b, 11c, 12b, and 12c are opened, and the movable legs 200FL, 200FR, 200BL, and 200BR are driven under the control of the control unit 110 to move the jack legs 210 to the outside of the container body 10. protrude. Next, the jack legs 210 are extended until each jack pad 213 protrudes downward from the bottom wall 16 of the container body 10 and the container body 10 is supported on the base B placed on the ground as shown in FIG. . As a result, after the container body 10 is separated upward from the loading platform of the vehicle 6 , the vehicle 6 is moved forward and separated from the container 1 . Next, the jack legs 210 are contracted to lower the container body 10 to the state shown in FIG. Further, the container body 10 is lowered to bring the bottom wall 16 of the container body 10 into contact with the ground. Then, the controller 110 drives the movable legs 200FL, 200FR, 200BL, and 200BR, thereby accommodating the jack legs 210 in the container body 10 .

After the container 1 has been lowered and installed on the ground as described above, the container 1 can be translated or rotated as follows in order to adjust its installation position. The following steps are performed by the controller 110 controlling the operations of the movable legs 200FL, 200FR, 200BL and 200BR. In addition, the following steps are assumed to start from a state in which the container body 10 is placed on the ground and the jack legs 210 are retracted and housed in the container body 10 .

(parallel movement)
A case of moving the container 1 in parallel will be described. First, each jack leg 210 is made to protrude to the side of the container body 10 . Here, the movable legs 200FL, 200FR, 200BL, and 200BR are allowed to assume the state shown in FIG. 7 in plan view, for example. That is, the jack legs 210 of the movable legs 200FL and 200BL are protruded relatively close to the left side wall 11 of the container body 10, and the jack legs 210 of the movable legs 200FR and 200BR are It is protruded at a position relatively separated from the right side wall 12 of the container body 10.例文帳に追加Then, the jack legs 210 are brought into a supporting state, and the container body 10 is separated above the ground to the state shown in FIG. From this state, the jack legs 210 of the movable legs 200FL and 200BL are moved relative to the container body 10 in a leftward projecting direction, and the jack legs 210 of the movable legs 200FR and 200BR are moved. , relative to the container body 10 in the direction to pull it in to the left. At this time, the relative movement of all jack legs 210 with respect to the container body 10 is the same speed. As a result, the container body 10 moves to the right with respect to the ground, resulting in the state shown in FIG. Next, the container body 10 is lowered onto the ground. Then, the jack legs 210 of the respective movable legs are retracted, and the jack legs 210 are accommodated in the container body 10 . As described above, the installation position of the container 1 can be reset to a position shifted to the right from the initial position.

(rotational movement)
A case in which the container 1 is rotated will be described. First, each jack leg 210 is made to protrude to the side of the container body 10 . Here, the movable legs 200FL, 200FR, 200BL, and 200BR are made to assume the state shown in FIG. 9 in plan view, for example. That is, the jack leg 210 of the movable leg 200FL is positioned relatively close to the left side wall 11 of the container body 10, and the jack leg 210 of the movable leg 200BR is positioned relatively close to the right side wall 12 of the container body 10. overhang. Also, the jack leg 210 of the movable leg 200FR is positioned relatively apart from the right side wall 12 of the container body 10, and the jack leg 210 of the movable leg 200BL is positioned relatively apart from the left side wall 11 of the container body 10. overhang. Then, the jack legs 210 are brought into a supporting state, and the container body 10 is separated above the ground to the state shown in FIG.

From this state, in the front leg pair 20, the jack legs 210 of the movable legs 200FL are moved relative to the container body 10 in the direction of projecting leftward, and the jack legs of the movable leg 200FR are moved. The portion 210 is moved relative to the container body 10 in the direction of retraction to the left. Further, in the rear leg pair 30, the jack leg 210 of the movable leg 200BL is moved relative to the container body 10 in a rightward drawing direction, and the jack leg 210 of the movable leg 200BR is moved. , relative to the container body 10 in the direction of projecting to the right. As a result, the front end of the container body 10 provided with the front leg pair 20 moves to the right with respect to the ground, and the rear end of the container body 10 provided with the rear leg pair 30 moves relative to the ground. Move left. Therefore, the container body 10 as a whole rotates clockwise in a plan view, and enters the state shown in FIG. 10 . The dashed lines α1 and β1 in FIG. 10 respectively indicate positions through which the width direction center plane C1 and the length direction center plane C2 pass when the container body 10 is in the state before rotational movement (the state shown in FIG. 9). 10 indicate positions through which the width direction center plane C1 and the length direction center plane C2 pass respectively when the container body 10 is in a state after rotational movement.

During rotational movement as shown in FIGS. 9 and 10, movable legs 200FL, 200FR, 200BL and 200BR move relative to housing sections 600FL, 600FR, 600BL and 600BR as follows while telescoping. do. That is, each movable leg rotates counterclockwise in a plan view around the wheel unit 240 or its vicinity with respect to each housing. Further, in each movable leg, the wheel unit 240 has a certain degree of freedom of movement within the range of the receiving portion 620 . As a result, in the movable leg portions 200FL and 200FR, each wheel unit 240 intersects the arm expansion/contraction direction along the right wall portion while maintaining the state in which the wheel body 241 is in contact with the right wall portion of the receiving portion 620. move in the direction In addition, in the movable legs 200BL and 200BR, each wheel unit 240 moves along the left wall of the receiving part 620 in a direction intersecting with the extension and contraction direction of the arm while maintaining a state in which the wheel body 241 is in contact with the left wall of the receiving part 620. move to In this way, each movable leg can rotate relative to each housing portion, and the wheel unit 240 can move relative to the receiving portion 620 . As a result, the movable legs are smoothly driven, and the container body 10 is smoothly rotated. As each movable leg rotates relative to each housing portion, the arm cylinder unit 220 contacts and compresses the spring unit 650 in the movable legs 200FR and 200BL. Also, in the movable legs 200FL and 200BR, the arm cylinder unit 220 contacts the spring unit 660 and compresses it. When the spring unit 650 or 660 is contracted to the limit, the limit switch is activated and the control section 110 stops the movement of the movable leg corresponding to the activated limit switch.

Next, the container body 10 is lowered onto the ground. Then, the jack legs 210 of the respective movable legs are retracted, and the jack legs 210 are housed in the container body 10 . The jack legs 210 are separated from the base B when the jack legs 210 are caused to take the retracted state. Therefore, the load rotating the arm cylinder unit 220 is also released. Therefore, the restoring force applied to the arm cylinder unit 220 by the spring units 650 and 660 causes the arm cylinder unit 220 to be tilted in the left-right direction (rotated with respect to the housing portion) as shown in FIG. 4, it returns to a position (predetermined position in the present invention) along the horizontal direction as shown in FIG. As described above, the installation position of the container 1 can be reset to a position rotated from the initial position in plan view.

[Main effects of the first embodiment]
According to the present embodiment described above, the jack legs 210 of the front leg pair 20 and the rear leg pair 30 are projected outside the container body 10 to be in a supported state, and then the movable legs 200FL and 200FR are in a supported state. One jack leg 210 is moved in the direction to project and the other jack leg 210 is moved in the direction to pull out, and one jack leg 210 of the movable legs 200BL and 200BR is moved in the direction to project and the other. move in the direction to pull out the jack leg portion 210 of the .

The jack leg 700 is a prism-shaped member extending in the vertical direction, and is manually or mechanically driven to expand and contract. As a result, the jack legs 700 can take a state in which the container body 10 is supported on the ground at one point and a state in which it is retracted from the ground. When the jack legs 700 support the container main body 10 at one point on the ground, the container main body 10 can rotate about the jack legs 700 with respect to the ground in plan view. In the pair of front leg portions 20 of the container 1′, each jack leg portion 210 is projected to the outside of the container body 10 to be in a supporting state, and the jack leg portion 700 is also in a state of supporting the container body 10, and then the movable leg portion One of the jack legs 210 of 200FL and 200FR is moved in the extending direction and the other jack leg 210 is moved in the pulling direction. As a result, the front portion of the container body 10 moves left or right. Therefore, the container body 10 can be rotated about the jack legs 700 with respect to the ground. Note that such jack legs 700 may be added to the first embodiment described above.
