[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a container that can be mounted on a vehicle, a railway freight car, or the like.
[0002]
[Prior art]
The conventional container has an inlet at the upper side to facilitate the input of garbage, earth and sand, etc., and the inlet canopy prevents the stored items such as earth and sand from scattering around the container during the transportation of the container. Can be opened and closed. The canopy is formed by fixing a canopy main body formed in a flat shape to a frame member formed in a lattice shape, and the canopy main body is reinforced by the frame member.
[0003]
[Problems to be solved by the invention]
However, in the above structure, since the canopy main body is formed in a flat shape, the portion that is not supported by the frame member is easily bent and deformed by its own weight, and the canopy main body is easily distorted as a whole. There was a drawback, and there was a problem that many reinforcing members had to be provided to solve this.
Further, since the frame member is formed long in the front-rear direction of the container, there is a problem that the intermediate portion thereof is bent downward by its own weight and easily deforms.
Therefore, the present invention provides a canopy structure in a container with a canopy opening / closing device that can reliably prevent deformation of the canopy without providing an extra reinforcing member.
[0004]
[Means for Solving the Problems]
The present invention is a container provided with a canopy opening and closing device that forms an inlet on the upper side and opens and closes by moving the inlet to one side of the canopy formed so as to be able to refract in a pair of left and right. The frame member includes a frame member in which a vertical frame and an arc-shaped horizontal frame are combined in a lattice shape, and a side-falling arc-shaped canopy main body fixed to the frame member. And a cover composed of a left side cover is fixed, and the cover is disposed between the canopy and a top plate of the container in which the insertion port is formed. It is formed in the same arc shape as the canopy and is fixed to the canopy, the lower end edge of the cover is formed linearly along the upper surface of the top plate, and the right and left covers are one Side cover is characterized in that each of the lower end in a state of entering into the inside of the cover on the other side are rotatably supported to each other.

At a position below the floor surface 9 of the side wall 7, a pair of insertion ports 14 are provided on the front and rear and on the left and right so that the fork of a forklift can be inserted to lift the container 1.
[0008]
Further, an openable / closable canopy opening / closing device 15 for covering the insertion port 10 is provided above the top plate 11. The canopy opening / closing device 15 prevents the contents from being scattered when the container 1 is transported by the transport vehicle 2 or the railway freight car. A rectangular block-like lower base 16 is fixed to the lower end of the column 6, and the lower base 16 is a hole 17 that can be engaged with and disengaged from a dump frame 4 of the transport vehicle 2 and a twist lock (not shown) provided on a railway freight car. Is formed, and the lower end of the lower base 16 is located slightly lower than the lower end of the side wall 7.
[0009]
On the other hand, a flat plate-like upper base 18 having the same shape as the lower surface of the lower base 16 is fixed to the upper end of the support 6 so that the lower base 16 can be placed on the upper base 18. In addition, a lateral L-shaped stopper 19 is fixed to the outer periphery of the upper base 18 so as to prevent the lower base 16 placed on the upper base 18 from shifting back and forth and from side to side. Furthermore, the position of the upper base 18 is set to be slightly higher than the canopy opening / closing device 15, and the lower surface of the upper container 1 does not interfere with the canopy opening / closing device 15 of the lower container 1 when the containers 1 are stacked. It is like that.
[0010]
Next, the canopy opening / closing device 15 will be described. The canopy opening / closing device 15 includes a canopy 20 that can close the insertion port 10 and a drive device 21 that opens and closes the canopy 20. As shown in FIGS. 10 to 13, the canopy 20 is divided into left and right parts so that it can be refracted. First, the frame member 22 is divided into left and right parts (upper and lower parts in FIG. 11). Three vertical frames 22b are formed in a lattice shape, and only the horizontal frame 22a is formed so as to descend in an arc shape from the center to the side. Further, a rotation shaft 23 is fixed to a side end portion (upper end in FIG. 11) of the one side frame member 22, and this rotation shaft 23 is supported by a bearing 24 erected on the top plate 11.
[0011]
A plate-shaped canopy main body 25 is riveted to the upper part of the frame member 22, and the entire canopy main body 25 has an arc shape along the horizontal frame 22a. Thus, since the canopy main body 25 has an arc shape, the occurrence of distortion between the frames can be reduced without providing a large number of horizontal frames 22a, and the canopy main body 25 can bend due to the weight of the vertical frame 22b. It is possible to prevent the vertical frame 22b from being bent.
[0012]
A vertical cover 26 is fixed to the front and rear surfaces of the frame member 22, and the left cover 26 (left side in FIG. 12) slightly enters the inside of the right cover 26 (right side in FIG. 12). When the canopy 20 is opened, the left and right canopies 20 are refracted around this pivot point Y.
At the front and rear positions of the canopy main body 25, arms 27 are arranged, respectively. The arms 27 support the right canopy 20 when the canopy 20 is opened and closed, and reduce labor when opening and closing the canopy 20. That is, the base end of the arm 27 is pivotally supported on the top plate 11 so as to be able to turn left and right, and a pair of coil springs 29 provided between the regulating member 28 fixed to the arm 27 and the top plate 11. Are provided so that the elastic force acts in a direction opposite to the direction in which the canopy 20 is rotated by its own weight.

The center point X of the rotating shaft 23, the shaft fulcrum Y of the left and right canopy 20 and the center point Z of the shaft 32 of the mounting member 31 are arranged. The connected line XYZ (dashed line) is refracted downward, and the line XYZ becomes a straight line (FIG. 21b) while the canopy 20 is opened, and the distance between X and Z is the maximum at that time. Therefore, the long hole 30 can absorb this change.
[0014]
Reference numeral 34 denotes a canopy lock device for holding the canopy 20 in a closed state. As shown in FIGS. 10 and 15 to 19, the canopy locking device 34 includes a pin 35, a hook 36, a connecting member 37, a spring 38, an operating lever 39, a stopper 40, and a regulating member 41.
The pin 35 protrudes at the center of one side surface of the canopy 20 (side surface opposite to the rotating shaft 23 side). The hook 36 is pivotally supported on the side wall 7 of the container 1 close to the pin 35, and can be engaged with the pin 35 by rotating the hook 36 in the front-rear direction. The hook 36 is connected to one end of an operation lever 39 via an arm 36 a integrated with the hook 36 and a connecting member 37. The operation lever 39 is pivotally supported by a rod 42 at the lower part of the side wall 7 (below the floor surface 9), and a handle 39a is formed at the other end.

Further, a spring 38 is attached to the connecting member 37 so that the hook 36 is rotated in the disengagement direction and the operation lever 39 is rotated counterclockwise. It can be held in the engaged state. That is, the restricting member 41 pivotally supports one end of the L-shape so as to be pivotable toward the side wall 7, and the other end restricts the counterclockwise rotation of the operating lever 39 by rotating downward to keep the hook 36 engaged. When it is rotated upward (FIG. 18), the restriction of the operation lever 39 is released, and the operation lever 39 is rotated counterclockwise by the spring 38 force and the operator's force (FIG. 19). The engagement state is released. When the hook 36 is in the engaged state, the operating lever 39 is rotated clockwise until it abuts against the stopper 40 against the force of the spring 38, and the regulating member 41 is rotated downward to engage the hook 36. It can be held in the combined state (FIG. 18).

A part thereof enters the recess 55. Further, a hook 58 is pivotally supported below the floor surface 9 so as to be pivotable up and down, and a part of the hook 58 protrudes partly from the opening 9b of the girder 9a and a pin 57 that enters the recess 55 of the receiving member 56 is inserted. It is supposed to be tied up.
[0020]
The end of the hook 58 is connected to the rod 61 via a connecting member 59 and a refractive link 60. The connecting member 59 is provided with a spring 62 so as to always urge the hook 58 in the direction of releasing the lashing. Further, when the hook 58 reaches the locked position due to the rotation of the rod 61, the refractive link 60 is positioned beyond the dead point as shown in FIG. 25a, so that the locked state of the hook 58 can be maintained. ing.
[0021]
The end of the rod 61 protrudes from the hole 63 in the side wall 7 as shown in FIGS. 26 and 27 to form a connecting portion 64 having the same shape as the connecting portion 49 of the hydraulic pump 44. The handle 50 to be used can also be used. Reference numeral 65 denotes a bearing for supporting the rod 61.
The main lock device 53 is used to securely hold the rear lid 12 together with the auxiliary lock device 54 in a closed state, and to make the closed state strong. 28 and 29, first, a seal member 66 and an engagement member 67 are provided on the beam 9a below the floor surface 9, and the seal member 66 is closed when the rear lid 12 is closed.

It can be done.
[0024]
In this embodiment, the stopper fixed to the upper base is formed in an L shape. However, even if the stopper is formed in a rectangular frame shape so as to surround the entire circumference of the upper base, the same effect is obtained. It is. Further, the drive device of the canopy opening / closing device is constituted by a hydraulic pump and a hydraulic cylinder, but the drive device may be formed by a chain or a gear. Further, although the lower lock device is constituted by the main lock device and the auxiliary lock device, the lower lock device may be constituted by only one of the main lock device and the auxiliary lock device. Furthermore, the shaft fixed on the arm side is connected to the long hole formed on the canopy side, but the same effect can be obtained by connecting the shaft fixed on the canopy side to the long hole formed on the arm side. I have it.
[0025]
The present invention is constructed as described above, and the operation will be described next.
First, when storing containers 1, if the site to be stored is large, store them one by one as shown in FIG. 3, and if the site is small, store containers 1 by stacking them as shown in FIG. To do. That is, when the containers 1 are stacked, the fork of the forklift is put into the insertion port 14 of the container 1 and the container 1 is lifted, and the lower base 16 of the lifted container 1 is placed on the upper base 18 of the separate container 1 in this way. Stack up.
[0026]
At that time, since the canopy opening / closing device 15 is lower than the upper base 18, there is no danger that the bottom surface of the upper container 1 interferes with the lower container 1, and the upper container 1 tends to shift somewhat due to vibration or the like. In addition, since the lower base 16 is regulated by the stopper 19, it is possible to reliably prevent the upper container 1 from being displaced.
Next, the case where the container 1 is used will be described. The empty container 1 is mounted on the transport vehicle 2 or the railway wagon in FIG. After the container 1 is lowered to the work site, the operation lever 39 of the canopy lock device 34 is operated to unlock the canopy 20. That is, when the regulating member 41 is rotated, the operation lever 39 is rotated in the direction of the arrow in FIG. 19 by the force of the spring 38 and the force of the operator, and the locked state by the hook 36 is released. At that time, since the unlocked state can be grasped also by the indicator needle 43 located on the opposite side wall 7, the risk of damaging the canopy locking device 34 by opening the canopy 20 in the locked state is prevented. Can do.
[0027]
When the unlocking of the canopy locking device 34 is completed, the handle 50 is attached to the connecting portion 49 of the hydraulic pump 44 and manually rotated in the normal rotation direction to operate the hydraulic pump 44. The pressure oil delivered from the hydraulic pump 44 is supplied to the hydraulic cylinder 45 through the pipe 46, and the hydraulic cylinder 45 is operated to rotate the canopy 20 in the opening direction. At this time, since the arm 27 supporting the canopy 20 is provided with the coil spring 29, the canopy 20 can be opened by a slight handle operation.
[0028]
Immediately before the start of canopy 20 release, as shown in FIG. 20b, the line XYZ is refracted downward, so the linear distance of XZ is short, and the shaft 32 of the mounting member 31 is located on the left side of the long hole 30 of the arm 27. It becomes. When the canopy 20 is further rotated and the line XYZ becomes a straight line (FIG. 21b), the distance of XZ becomes maximum, the shaft 32 moves to the right side of the long hole 30, and the canopy 20 is absorbed while absorbing the displacement of the shaft 32 with respect to the arm 27. Can be supported. When it is further rotated, it passes through FIG. 22b and reaches FIG. 23b, and the container 10 is fully opened. At this time, since the shaft fulcrum Z is located above the right canopy 20, the canopy 20 can be brought closer to the side wall 7 of the container 1, and the amount of protrusion of the canopy 20 toward the container 1 becomes small and narrow. Container 1 can also be installed at a place.
[0029]
In that state, a container such as garbage or earth and sand is introduced. When the charging is completed, the handle 50 attached to the connecting portion 49 of the hydraulic pump 44 is reversed, the pressure oil is pumped in the reverse direction, and the canopy 20 is rotated from the state of FIG. 23a to pass the container through FIGS. 22a and 21a. 1. Close the top inlet 10 (FIG. 20a). At that time, since the canopy 20 has an arc shape, earth and sand can be piled up along it.
[0030]
When the canopy 20 is closed, the operation lever 39 of the canopy lock device 34 is rotated clockwise against the spring 38 (FIG. 18), and the operation lever 39 is held at that position by the regulating member 41. As a result, the upper hook 36 engages with the pin 35 on the canopy 20 side, and the opening of the canopy 20 is restricted. During the transportation of the container 1, the hook 36 is detached due to vibration or the like and the canopy 20 is locked. It is possible to reliably prevent the release.
[0031]
When the operation is completed, the container 1 is placed on the dump frame 4 of the transport vehicle 2 by a forklift to be integrated, and transported to a waste disposal place. When arriving at the disposal site, the transport vehicle 2 is stopped, the handle 50 is attached to the nut 76 of the main lock device 53 at the rear of the container 1, and the engaging pin 74 is recessed in the engaging member 67 by operating the handle 50. Remove from 68. After that, it moves to the side of the container 1, attaches the handle 50 removed from the nut 76 to the connecting portion 64 on the auxiliary lock device 54 side, rotates the handle 50, rotates the refraction link 60, and releases the dead point. Then, the hook 58 is brought into a state of releasing the lashing. At this time, if the container 1 is full of contained items, the contained items may leak out from the container 1 by spreading the rear door 12 at the same time as the lashing is released. Since it is operating, it is possible to prevent the worker from getting dirty with the leaked contents.
[0032]
After that, when the dump frame 4 is tilted rearward around the rear hinge 5 by the lifting device 4a, the container 1 also tilts, and the lower part of the rear saddle door 12 is released from being locked. The door 12 is rotated by its own weight, and the contents of the container 1 are discharged to the rear of the container 1. At that time, when the canopy 20 is opened and the discharge efficiency is better, the dump frame 4 may be tilted after the canopy 20 is opened.
When the discharge of the container 1 is completed, the dump frame 4 is stored, the auxiliary lock device 54 is operated, the pin 57 of the rear door 12 is secured, and the main lock device 53 is also secured with the same handle 50. To do. Then, it transports to a container storage place with the transport vehicle 2 grade | etc., And drops the container 1 from the transport vehicle 2 in the said storage location.
[0033]
【The invention's effect】
As described above, according to the present invention, the canopy is formed by the frame member in which the vertical frame and the arc-shaped horizontal frame are combined in a lattice shape, and the arc-shaped canopy main body that is fixed to the frame member and descends laterally. As a result, distortion due to its own weight is less likely to occur even at locations that are not supported by the frame member, and deformation of the entire canopy main body can be reliably prevented without providing an extra reinforcing member.
Further, it is possible to prevent the vertical frame from being bent by its own weight due to the tensile force of the canopy body, and it is also possible to prevent the frame member from being deformed.
