Can be loaded on transport vehicles. As a result, the container can be efficiently transported regardless of the transport distance of the container.
[0004]
[Problems to be solved by the invention]
However, in a conventional container transport vehicle, when loading and unloading containers to and from the loading platform, not only the operation of raising and lowering the container by the container lifting device, but also the operation of moving the container lifting device in the vehicle front-back direction using both movable bodies. Had to do. For this reason, conventional container transport vehicles require not only a container lifting device for raising and lowering containers, but also a movable body for moving the container lifting device into and out of the vehicle from the loading platform. Sometimes a large working space was needed.

[0014]
[Action]
According to the first aspect of the present invention, when loading / unloading the container, the lifting / lowering frame is raised / lowered along the column by the frame lifting / lowering means, and the container is lifted (loaded) and lowered (loaded / unloaded) in the internal space of the storage cart. And). Thus, the container can be loaded and unloaded on the container transport vehicle without using a large forklift, a crane, or the like. As a result, the container can be efficiently taken into the storage trolley and transported regardless of the transport distance of the container. In addition, for example, when loading / unloading a container, the container is placed in the lifting frame and moved up / down, so that stable loading / unloading of the container with high safety can be performed. In addition, compared to a conventional container transport vehicle that involves not only raising and lowering the container but also moving the container in the front-rear direction, the structure is simpler and the cost can be reduced, and the space for loading and unloading the container is reduced. be able to.
[0015]
In particular, according to the second aspect of the present invention, the lifting frame is made to stand by at the upper part of the internal space before, for example, loading the container into the container transport vehicle. As described above, since the standby position of the lifting frame is located at the upper part of the internal space, the movement of the movable container with the casters can be particularly smoothly performed. For example, containers can be taken in and out from both sides of the vehicle.
When loading the container, the ascending position of the elevating frame is regulated by the ascending regulating means. Thereby, the lifting frame is unnecessarily raised in the internal space, and the loading position of the container is higher than the set position. As a result, it is possible to prevent the center of gravity of the container transport vehicle from rising and the traveling of the container transport vehicle from becoming unstable.
[0016]
Further, according to the third aspect of the present invention, when loading the container, the shaft is rotated to the rising regulation side of the lifting frame, and the stopper member is arranged at the projecting position. Thereafter, when the lifting frame is raised by the frame lifting means, the floating container stops at the container holding position. As described above, the lift of the container supported by the lifting frame is restricted by a simple structure, so that, for example, an electric motor with an encoder (servo motor) and a control unit for controlling the rotation speed of its output shaft are used. This eliminates the need for a special and expensive frame elevation control device that detects the elevation position of the elevating frame and controls its elevation. As a result, it is possible to reduce the cost of the ascent control means and, consequently, the cost of the container transport vehicle.
[0017]
According to the invention described in claim 4, the movement of each container in the internal space of the container transport vehicle is guided by the guide rollers. Thereby, when loading / unloading or transporting the containers, it is possible to prevent collision between the containers in the internal space.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 14, reference numeral 10 denotes a container transport vehicle according to an embodiment of the present invention. The container transport vehicle 10 has an internal space capable of storing three containers 11 with casters C, and is provided on both side walls. A storage trolley 12 in which a loading / unloading entrance 12a of the container 11 is formed, an elevating frame 13 which is disposed in a gap between the internal space and the container 11 and is hung by the container 11 and can be moved up and down integrally with the container 11; 12, a frame elevating means 14 for elevating the elevating frame 13, a plurality of hanging members 15 provided to be able to be taken in and out of the elevating frame 13, and hung on the bottom of the container 11, and each hanger member 15. A locking means 16 for locking the bottom of the container 11.
[0019]
The storage trolley 12 is a gate-shaped traction trolley (semi-trailer) having a rectangular shape in plan view on which the four columns 17 are arranged. The storage trolley 12 is pulled by a tractor (not shown), and a caster C for traveling is disposed at the bottom of each support 17.

The upper frame plate 20 is provided with a total of four guide frames 21 each having a rectangular shape on the side surface at two end portions in the length direction of the internal space and at two locations that divide the internal space into approximately three equal parts in the length direction. It is arranged. In each guide frame 21, a total of six vertically long guide rollers 21a are pivotally supported at a constant pitch with the axial direction directed vertically.
[0020]
A pair of long hydraulic cylinders 22 with the length direction of each rod 22a directed to the length direction of the storage trolley 12 is provided on the outer surface of both long side frames 20a constituting a part of the upper frame plate 20. Are arranged. A double sprocket having a small diameter first sprocket S1 and a second sprocket S2 having the same rotation axis is rotatably supported at the tip of each rod 22a. A pair of sprockets S3, S4 are individually disposed on the outer surfaces of both ends of the both side frames 20a on the long side. Since the movements of the piston rods 22a of both hydraulic cylinders 22 are synchronized (synchronized) by the shafts S31 and S41 connecting the pair of sprockets S3 and S4, the elevating frame keeps its posture constant (horizontal) during elevating. To). Furthermore, large-diameter first sprockets S5 are respectively disposed on the outer surfaces of the long side frames 20a at positions slightly opposite to the hydraulic cylinder 22 from the longitudinally intermediate portions of the both frames 20a. Supported.
[0021]
Each of the first sprockets S1 and S5 is provided with a pair of first chains 23, respectively. Each of the first chains 23 has one base end fixed to an upper position near the sprocket S5 on the outer surface of both side frames 20a on the long side through a pin P1, and the other bases are fixed to each other. The ends are fixed to the corners on one end side in the length direction of the lifting frame 13. Here, the routing of both first chains 23 will be described with reference to each one of the base ends. Both first chains 23 extend from the base end of each one to the first sprocket S1 having a small diameter, and are bridged and folded over the first sprocket S1. Thereafter, both first chains 23 are bridged over the large-diameter sprockets S5 and further folded back. Then, when the first chains 23 reach one ends of the side frames 20a on the long sides, the first chains 23 are bridged over the sprocket S3, and the traveling directions are respectively changed downward. Then, the other base ends of the first chains 23 are respectively fixed on both corners on one end side of the lifting frame 13.
[0022]
In addition, a pair of second chains 24 are bridged between the respective second sprockets S2 and S4. Each of the second chains 24 has one base end fixed to a lower position near the sprocket S5 on the outer surface of the long side frame 20a on the long side via a pin P2, and the other bases of the two second chains 24 are fixed to each other. The ends are fixed to the corners on the other end side in the length direction of the lifting frame 13. Specific routing of both second chains 24 will be described with reference to the base end of each one. Both second chains 24 extend from one base end to the second sprocket S2 having a small diameter, and are bridged over the second sprocket S2 and folded. Thereafter, when the second chains 24 reach the other ends of the side frames 20a on the long sides, the second chains 24 are wound around the sprocket S4, and change the traveling direction downward. Then, the other base ends of the two second chains 24 are respectively fixed on both corners on the other end side of the lifting frame 13.
The frame lifting / lowering means 14 mainly includes a hydraulic cylinder 22, sprockets S1 to S5, and chains 23 and 24.
[0023]
Next, the lifting frame 13 will be described in detail with reference to FIG. 4, FIG. 9, FIG. 12, and FIG.
As shown in FIGS. 4, 9, 12 and 13, the lifting frame 13 is a frame slightly smaller than the internal space of the storage trolley 12 in plan view. A pair of shafts 26 are rotatably arranged between both ends in the width direction of the lifting frame 13 via a number of bearings 25. Both ends of each shaft 26 protrude outside the lifting frame 13. Two pairs of large-diameter sprockets 27 are provided on the base side of these protruding portions.
Among the sprockets 27, an endless chain 28 is bridged between the sprockets 27 arranged on both short sides of the elevating frame 13 in an eight-shaped crossing manner.
Thereby, the rotation directions of the shafts 26 that rotate synchronously are opposite to each other. In the vicinity of the short side end of the lifting frame 13, the distal end of each stopper member 29, which will be described later, is held at a position slightly separated from the shaft support portion of the shaft 26, and the downward rotation of each stopper member 29 is performed. Four abutment plates 30 for regulating the angle of movement are provided to project outward.
[0024]
In addition, at both ends of each shaft 26, at the front end side of a portion that protrudes outward, a base portion of a stopper member 29 is fixed. These stopper members 29 have a small plate shape, and a protruding position (horizontal position (FIG. 13)) for restricting the elevation of the lifting frame 13 with the rotation of the shaft 26, and a retracted position (vertical position) for releasing the restriction. Position (FIG. 12)). At the lower part of each support 17, only when the container 11 is loaded, the stopper members 29 arranged at the protruding positions are latched, so that the stopper latch portions 31 for restricting the elevation of the lifting frame 13 are provided. I have.
[0025]
The stopper retaining portion 31 is a short rectangular member having a tip protruding in the direction of the lifting frame 13, and is fixed to one side surface of the corresponding column 17 via a bracket 32. A stopper member 29 that has reached the retracted position is leaned against the surface of each column 17 on the side of the lifting frame 13. As the lifting frame 13 moves up and down, the stopper member 29 slides up and down with the stopper member 29 in the leaning state. The moving guide rail 33 is fixed. A gap d is formed between the sliding guide rail 33 and the stopper engaging portion 31 so that the stopper member 29 in the upright state can be passed with ease (FIGS. 12 and 13).
The stopper member 29, the abutment plate 30, the stopper engaging portion 31, the bracket 32, and the sliding guide rail 33 constitute an ascent control means 40 which controls the highest position of the elevating frame 13 when loading the container.
[0026]
Next, a method of transporting containers by the container transport vehicle 10 according to one embodiment will be described with reference to FIGS.
First, the container transport vehicle 10 is connected to a tractor (not shown). At this time, one of the stopper members 29 is rotated upward about the shaft 26. Then, the other shaft 26 rotates synchronously in the opposite direction via the endless chain 28. As a result, each stopper member 29 is leaned against the corresponding slide guide rail 33, and each latch member 15 is also leaned against the inner surface of the lifting frame 13.
[0027]
Next, when the rods 22a of the hydraulic cylinders 22 are retracted, the chains 23, 24 are dragged upward, the horizontal state is maintained along the guide rails 18, and the lifting frame 13 is raised to the upper end of the internal space. I do. At this time, each stopper member 29 slips through the gap d. The maximum rising position is the standby position of the lifting frame 13 before the container 11 is loaded (FIGS. 1 and 3).
Next, the tractor is operated, the container transport vehicle 10 is moved in a predetermined direction, and the three containers 11 arranged on the ground at a constant pitch are taken into the internal space from the loading / unloading entrance 12a on one side of the storage truck 12. In the internal space of the storage trolley 12, the containers 11 are guided to a predetermined storage position by a number of guide rollers 21a so that the containers 11 do not collide with each other.
[0028]
Thereafter, the rods 22a of both hydraulic cylinders 22 are made to protrude. As a result, both chains 23 and 24 extend downward and descend to the lower end of the internal space with the lifting frame 13 being horizontally arranged (FIGS. 5 and 6).
Next, one of the stopper members 29 is rotated downward about the shaft 26. This causes the other shaft 26 to rotate synchronously in the opposite direction via the endless chain 28. As a result, the distal end portion of each stopper member 29 is supported in a horizontal state by the predetermined contact plate 30, and each of the locking members 15 is also arranged horizontally. Next, in this state, the rods 22a of both hydraulic cylinders 22 are retracted again. As a result, both chains 23 and 24 are dragged upward, and the lifting frame 13 is raised in a horizontal state. However, when the elevating frame 13 slightly rises to reach the container loading position, each stopper member 29 is hooked on the stopper hooking portion 31, and its rising is regulated. As a result, each container 11 is held at the container loading position (FIGS. 9B, 10 and 11).
Thereafter, the tractor is operated to transport the container transport vehicle 10 in which the container 11 is stored to a predetermined moving position. Each container 11 is unloaded at the destination. In that case, the above operation is performed in reverse.
[0029]
As described above, when the container 11 is loaded and unloaded, the container 11 is moved up and down as the lifting frame 13 is moved up and down. Therefore, the container 11 can be loaded and unloaded on the container transport vehicle 10 without using a large forklift, a crane, or the like. . As a result, regardless of the transport distance, the container 11 can be efficiently taken into the internal space of the storage trolley 12 and transported. In addition, since the container 11 is arranged in the lifting frame 13 and the lifting frame 13 is moved up and down along the columns 17, it is possible to stably load and unload the container 11 with high safety. In addition, for example, when loading / unloading the container 11, the structure is simpler and the cost can be reduced as compared with a conventional container transport vehicle that involves not only raising and lowering the container 11 but also moving the container 11 in the front-rear direction of the vehicle. It is possible to reduce the space for the loading and unloading operation of the eleventh embodiment.
Further, since the standby position of the lifting frame 13 is set at the upper part of the internal space, the container can be freely taken in and out. The loading / unloading direction is also free.
[0030]
Further, at the time of loading the container 11, the lifting position of the lifting frame 13 is regulated by the lifting restricting means 40, so that the lifting frame 13 is unnecessarily raised in the internal space, and the loading position of the container 11 is higher than the set position, As a result, it is possible to prevent the traveling of the container transport vehicle 10 from becoming unstable due to an increase in the center of gravity of the container transport vehicle 10.
When the container is loaded, the elevation of the container 11 supported by the elevating frame 13 is restricted by the simple structure as described above. For example, the ascending position of the elevating frame is detected, and the elevating frame is specially controlled. An expensive frame raising control device is not required. As a result, the cost of the ascent control means 40 can be reduced, and the cost of the container transport vehicle 10 can be reduced.
Then, since the movement of each container 11 in the internal space is configured to be guided by the guide rollers 21a, it is possible to prevent collision between the containers 11 in the internal space when loading / unloading and transporting the container 11. Can be.
Further, as shown in FIG. 14, the container transport vehicle 10 can be employed not for transporting the container 11 with the casters C but for transporting the container 11 placed on the pallet P. In that case, the hanging member 15 is hung on the pallet P, and each container 11 is lifted.
[0031]
【The invention's effect】
According to the first aspect of the present invention, when loading / unloading the container, the container is moved up and down in the storage trolley as the lifting frame is moved up and down. Therefore, a large forklift, a crane or the like is not required at the time of loading / unloading. Further, since the container is accommodated in the lifting frame and moved up and down, the safety of lifting and lowering the container is high, and stable loading and unloading of the container becomes possible. As a result, regardless of the transport distance, the container can be efficiently taken into the storage trolley and transported. In addition, for example, when loading / unloading containers, the structure becomes simpler and lower cost compared to a conventional container transport vehicle that involves not only raising and lowering the containers but also moving the containers in the front-rear direction. The space for the unloading operation can be reduced.
[0032]
In particular, according to the second aspect of the present invention, the standby position of the lifting frame is set at the upper part of the internal space, so that the container can be carried in and out freely. In addition, it is possible to take in and out the vehicle from both sides.
Also, when loading containers, the lifting position of the lifting frame is regulated by the lifting control means, so that the lifting frame is unnecessarily raised in the internal space, and the loading position of the container is higher than the set position. Can be prevented from becoming high and the running of the container transport vehicle becomes unstable.
[0033]
According to the third aspect of the invention, when the container is loaded, the lifting of the container supported by the lifting frame is regulated by a simple structure. For example, the rising position of the lifting frame is detected and the lifting is controlled. This eliminates the need for a special and expensive frame raising control device. As a result, the cost of the ascent control means can be reduced, and the cost of the container transport vehicle can be reduced.
[0034]
According to the fourth aspect of the present invention, since the movement of each container in the internal space of the container transport vehicle is guided by the guide rollers, collision of containers in the internal space is prevented when loading / unloading or transporting containers. can do.
