Description

  The present invention relates to a freight vehicle, and more particularly to a freight vehicle having a cargo bed having a novel structure that can sufficiently open a ceiling of a cargo compartment.

In carrying out the logistics business, it is necessary to adopt a system that responds to various requirements, such as demands on the loading status due to the characteristics of the luggage itself, logistics systems, and requests for effective operation management.
For this reason, the loading platform of a freight vehicle such as a truck or a trailer used at a transportation site is required to have a structure that can flexibly meet the above requirements. On the other hand, it may be preferable to have a specific platform structure due to the nature of the luggage. In this case, naturally, versatility must be sacrificed.

  For example, in the case of a truck that transports raw wood chips to a paper mill, for example, an open-type loading platform suitable for bulk loading, or a track called a deep loading platform with an open upper part and a peripheral wall panel fixed is used. . On the other hand, from the management point of view of the logistics business or the customer's request, for example, after delivering raw wood chips as luggage, the truck is also used effectively to transport the paper roll as a product from the paper mill. Needless to say, business efficiency can be improved. However, in the case of a loading platform structure specialized for chip transfer as in the present situation, it is not suitable for loading a product of an original fabric roll, and the return path is unavoidably operated in an empty state.

By the way, open-side freight vehicles have become widespread as cargo bed structures that can meet such various conditions in general. In this case, since both sides of the cargo compartment are greatly opened by applying the side opening unit, a cargo handling access space can be taken sufficiently and the sealability of the cargo compartment is excellent.
However, since the panel of the side opening unit itself cannot exert sufficient strength against the holding action of the load, for example, after storing the pallet together with the pallet in a luggage compartment, the load is put on a stable state of loading. Measures to obtain are taken. In place of such measures, if the side opening unit is lowered after the completion of loading, packing-like stuffing is applied to the remaining space on the upper part, and load holding is actively performed, a more effective cargo handling operation can be realized. You can expect. On the other hand, it is also possible to consider loading a load on this portion of the remaining space on the ceiling.
However, in the case of the current side-opening type freight vehicle, once the side-opening unit is closed, the cargo compartment is completely closed and access for work is not possible. As a result, the upper residual space is not effectively used. This is due to the fact that the open side freight vehicle has been highly evaluated for its excellent versatility, excellent cargo handling, and excellent airtightness, and there have been few attempts to improve it. .

Of course, there is a type in which the side panel of the side opening unit is lifted up to a vertical state to allow cargo handling from above (Non-Patent Document 1).
However, this type requires a sufficient space for opening the side opening unit, and is not necessarily good at the handling site. In addition, a configuration in which the ceiling surface of the side opening unit is configured to form a grid with a frame and allows reception of chips and the like is also disclosed in Non-Patent Document 1 described above. Due to the existence, only so-called bulk goods can be handled, and general-purpose cargo handling from above cannot be performed.

Further, side-side tilts 7 are provided on the left and right side edges of the floor surface 3. The side tilt 7 is opened to the outside by using the lower side of the floor surface 3 as a hinge. When the side tilt 7 is long in the longitudinal direction of the loading platform 1, the side tilt 7 is divided into two parts in the front and rear in consideration of operability. An insertion pillar 71 is provided at the center so as to hold it.
Furthermore, a side surface opening unit 10 is provided that divides the range of the side peripheral portion from the upper end of the side wing 7 to the ceiling surface. The side surface opening unit 10 is symmetrically mounted on the loading platform 1 as an example. The pivot fulcrum is provided on the ceiling beam 43, and is opened in the shape of a wing piece to the left and right around this.

  The peripheral wall panel 8 described in the claims of the utility model registration includes the members of the peripheral surface portion that rises upward from the floor surface 3 of the loading platform 1. In this embodiment, the rear door 5, the front panel 6, the side tilt 7, and the side wall portion (side panel 13) of the side surface opening unit 10 are configured. Therefore, even if it is the case of the surrounding wall panel 8, it is an aggregate | assembly of what has a partially different function, and says the member which bears the effect | action which substantially surrounds the side periphery of the loading platform 1.

  Furthermore, about the ceiling panel 2 with which the substantial structure of this invention is provided, it is provided in the upper surface side of the side surface opening unit 10 as an example. First, the side opening unit 10 will be described. The side opening unit frame 10 is configured by a side opening unit frame 11 in an inverted L shape when viewed from the front or the back. It is a part of panel 2. That is, the portion constituting the ceiling panel 2 is constituted by a wing plate ceiling base frame 11a, a wing plate ceiling corner frame 11b on the side wall of the loading platform 1, and a wing plate ceiling width frame 11c connecting them in the width direction. Is configured as a long and narrow rectangular frame in a plan view by a vane ceiling width frame 11c provided between the front end and the rear end of the side surface opening unit 10 and further between them. Further, a side panel 13 is supported below the vane ceiling corner frame 11b. Of course, the side panel 13 itself also includes an appropriate frame member, and an aluminum plate or the like is stretched on the frame member. However, the details of each member will be omitted.

And the blade hinge 12 is provided so that the ceiling beam 43 and the blade base ceiling base frame 11a are rotatably connected. The side surface opening unit 10 centering on the blade hinge 12 is opened upward from the closed state with the longitudinal direction of the cargo compartment as the pivot axis, and is disposed between the blade plate ceiling width frame 11c and the ceiling beam 43. The blade is shifted up and down by the vane plate shift cylinder 14 provided in the cylinder.
That is, the cylinder body 14a side is rotatably attached to the blade shift cylinder base pivot 15 on the ceiling beam 43 side, and the tip of the cylinder rod 14b is provided on the blade plate ceiling width frame 11c in the side opening unit frame 11. The blade plate shift cylinder is rotatably attached to the movable pivot 16. As a result, the side opening unit 10 is opened and closed in response to the expansion and contraction of the blade shift cylinder 14.

The upper part of the side opening unit 10 is the ceiling panel 2, and this part is configured to be opened with the longitudinal direction of the luggage compartment as the rotation base axis. About this ceiling panel 2, the form of both the folding type ceiling panel 20 and the hatch type ceiling panel 120 can take.
First, the half-fold type ceiling panel 20 will be described. In this case, the ceiling panel unit 21 in which the base panel 21A and the free end panel 21B are combined is opened in a folded shape. That is, first, the base panel 21A is pivotally attached to the wing plate ceiling base frame 11a in the side opening unit frame 11 by the base panel hinge 22a serving as a pivot base. In addition, the base panel 21A and the free end panel 21B are configured to be bent in a mountain-like manner by the middle folding hinge 22b. The free end panel 21B has a front end roller 23 attached to the front end side via a roller stay 23a.

  Such a half-folded ceiling panel unit 21 is opened and closed by using the ceiling panel cylinder 24. The ceiling panel cylinder 24 is configured such that a panel cylinder body 24a is pivotally connected to a wing plate ceiling base frame 11a in the side opening unit frame 11 at a panel cylinder base pivot 25a. The base panel 21A is pivotally connected to the panel cylinder movable pivot 25b side.

Such a folding center type ceiling panel unit 21 is further provided with a front end locking structure 26, a center shield structure 27, a middle folding part shield structure 28, and a front end shield structure 29 in order to maintain a completely sealed state of the cargo compartment. With
First, the tip lock structure 26 will be described.
As shown in FIGS. 5 and 6, a part of the front end lock structure 26 is provided on the front end side of the hatch guide rail 17 provided using the inner side surface of the vane ceiling width frame 11c in the side opening unit frame 11 (loading platform 1). At the left and right end sides). That is, the hatch guide rail 17 has a form along the entire width of the wing plate ceiling width frame 11c. However, the hatch guide rail 17 is lowered downward near the tip portion and close to the wing plate ceiling corner frame frame 11b. Part 171 is configured. On the other hand, an upper pressing piece 251 is provided on the side opening unit frame 11 side at this portion, and a space between the tip lowering portion 171 and the upper pressing piece 251 is a holding pocket 252.

  As a result, when the half-folded ceiling panel unit 21 is closed, the tip roller 23 is stored in the holding pocket 252, and the base panel 21A and the free end panel 21B are both connected in a flat plate state. In this case, a state where the free end is lifted upward around the base panel hinge 22a is completely avoided. Of course, the position of the tip roller 23 is important for fitting the tip roller 23 into the holding pocket 252, and the tip roller 23 is almost near the tip of the free end panel 21B, and in the vertical direction. The free end panel 21 </ b> B is provided with a height corresponding to the depth of the tip lowering portion 171.

Next, the center shield structure 27 will be described.
The center shield structure 27 is a shield structure between the rotation center of the side opening unit 10, that is, between the ceiling beam 43 and the base of the side opening unit 10 and the base panel 21 </ b> A of the ceiling panel unit 21. Specifically, as shown in FIG. 7, a flexible seal sheet 127A that allows opening and closing of the side opening unit 10 is stretched on the upper surface of the center of rotation, and this is further extended to the base panel 21A side. It constitutes.

Next, the half-fold shield structure 28 will be described.
As shown in FIG. 8 (a), this includes, as an example, an inverted channel-shaped folded portion covering plate 281 as a part of the base panel 21A. There is a rising portion 281a on the base end side, a top portion 281b is continuously provided on the upper surface thereof, and a distal end pressing portion 281c is provided on the other end of the top portion 281b. A folded portion weather seal 282 is provided so as to be held by such a folded portion cover plate 281. This is, for example, a hollow rubber-like member, and when the ceiling panel 2 is closed, as shown in the lower part of FIG. 8A, the folded portion weather seal 282 contacts the free end panel 21B on the lower surface. However, the upper part is pressed by the tip pressing part 281c in the center folding part cover plate 281 and, as a result, is pressed to the free end panel 21B with a certain elasticity, so that a sealed state appears. .

Next, the tip shield structure 29 will be described.
As shown in FIG. 6, as an example, a free end panel 21B is provided with a front end cover plate 291 that is an angle-shaped member, a front end weather seal 292 provided on the inner side (lower surface), and a side surface. The opening unit 10 is constituted by seal receiving ribs 293 provided on the blade ceiling corner frame 11b. That is, the front end cover plate 291 is a member having an angled cross section including a front projecting portion 291a and a tip lowering portion 291b, and a front end weather seal 292 is provided on the lower surface of the front projecting portion 291a. . In the closed state, the front end weather seal 292 is sandwiched between the seal receiving ribs 293, and the lower end 291 b of the front end cover plate 291 covers the outside of the upper end of the side panel 13. As a result, a sealing action is achieved.

The present invention uses the above-described configuration as one basic configuration and operates as follows.
≪Initial condition≫
First, a state in which the luggage compartments S in the loading platform 1 of the present invention are all closed will be described as a starting state.
In a state where all the side surface opening units 10, the side doors 7, and the rear door 5 are closed so as to constitute the peripheral wall panel 8, in the side surface opening unit 10, the lower end of the side panel 13 and the side doors 7 The joint surface is kept closed by a latch mechanism or the like. In this state, the blade shift cylinder 14 of the side opening unit 10 is in a completely contracted state.
On the other hand, the ceiling panel unit 21 constituting a part of the side surface opening unit 10 has a state in which the base panel 21A and the free end panel 21B are continuously flat and cover the ceiling surface of the cargo compartment S. . In this state, the ceiling panel cylinder 24 is in a contracted state.

≪Main cargo handling status≫
In the main cargo handling operation, the side surface opening unit 10 is opened while the ceiling panel unit 21 is closed as shown in FIG.
The opening of the side opening unit 10 in such a cargo handling operation is performed by extending the blade shift cylinder 14 to lift the blade plate ceiling width frame 11c.
At the same time, the side tilt 7 is lowered to allow the forklift to approach from the side, and the cargo handling operation from the side is performed. That is, for both loading and unloading, for example, the loading work B loaded on the pallet is handled using a forklift or the like.
At this time, the side surface of the loading platform 1 is sufficiently open, and the side panel 13 of the side surface opening unit 10 protrudes to some extent in a bowl shape, so that it functions as a rain guard in the case of outdoor cargo handling work such as raining. Work can be done while protecting B.
In addition, after the cargo handling operation is completed, in order to place the side surface opening unit 10 in the closed state, the blade shift cylinder 14 is contracted to obtain the closed state. Of course, prior to this work, the side-side tilt 7 is in a raised state.

≪Handling work from the ceiling surface≫
Next, when it is necessary to open only the ceiling panel 2 after maintaining the peripheral wall panel of the luggage compartment S in the loading platform 1, the ceiling panel cylinder 24 is extended as shown in FIGS. The ceiling panel unit 21 composed of the panel 21A and the free end panel 21B is raised so as to be raised in a folded manner.
Accordingly, the center-folded ceiling panel unit 21 is lifted around the center-fold hinge 22b, and the tip roller 23 on the tip side rolls on the hatch guide rail 17 and starts from the tip lowering portion 171 first. The free end panel 21 </ b> B is lifted toward the end side, and the free end panel 21 </ b> B raises the front end surface at once, and the front end cover plate 291 in the front end shield structure 29 is the blade ceiling corner frame 11 b in the side opening unit 10. While moving so as not to interfere with each other, it is drawn toward the base panel 21A side to obtain an open state.

In this way, the loading platform 1 can be obtained in a state where the ceiling panel 2 is completely opened while the longitudinal direction of the loading chamber is the rotation base axis, and the loading work, packing of packing members for holding the load B, etc. can be carried out from here. It becomes possible.
After such work is completed, the base panel 21A is laid down by contracting the ceiling panel cylinder 24 again. Along with this, the free end panel 21B also falls down while maintaining a half-fold shape, and finally, a state in which the base panel 21A and the free end panel 21B are formed into a single flat plate shape is obtained.
As can be understood from such an operation mode, various opening / closing drive structures for the ceiling panel 2 using the ceiling panel cylinder 24 as an example can be applied.
For example, hydraulic cylinders, hydraulic actuators, electric cylinders, electric actuators, gas dampers, screw jacks, pneumatic cylinders, pneumatic actuators, rod actuators, linear actuators, racks, pinion mechanisms, push-up devices that use winding springs, etc. The ceiling panel 2 can be opened / closed by being directly driven by these, or by combining a link, a wire, a pulley or the like with these devices.
In addition, the number of members for opening / closing driving of the ceiling panel 2 can be an appropriate number depending on the material of the aggregate of the ceiling and the ceiling length.

≪Maintenance of closed state: Maintenance of sealed state≫
At this time, the front end roller 23 in the free end panel 21B is in a state of being fitted into the holding pocket 252 and is maintained in a state in which the ceiling panel unit 21 is not opened even when subjected to an impact or the like. An appropriate number of tip rollers 23 can be attached according to the material of the ceiling skeleton and the ceiling length.
Further, by the middle folded shield structure 28, the middle folded weather seal 282 obtains a sealed state of the upper surface of the base panel 21A and the free end panel 21B at the middle folded section. Of course, the middle-folded part shield structure 28 is not limited to the form shown in FIG. 8A, but a simple structure in which a so-called mountain rubber or the like is arranged at the center as shown in FIG. 8B. It can be in any form.

Also, at the distal end portion, a sealing state on the distal end portion side is obtained by the action of the distal end weather seal 292, and further the distal end lowered portion 291b and the seal receiving rib 293 on the distal end portion cover plate 291.
Of course, the tip shield structure 29 is not limited to the configuration shown in FIG. 6 and can be a structure shown in FIG. That is, this embodiment is a combination of a pair of tip weather seals 292a and a tip weather seal 292b. First, the tip weather seal 292a is provided at the upper edge of the side panel 13. On the other hand, the tip weather seal 292 b is provided inside the tip cover plate 291 of the ceiling panel unit 21. When the ceiling panel unit 21 is closed, the two end weather seals 292a and 292b come into contact with each other and are pressed against a part of the ceiling panel unit 21 of the end weather seal 292. It is done.
In addition, although each shield structure was limited to the description of basic members, in order to ensure waterproofing, use a combination of waterproof rubber, waterproof rubber packing, resin packing, water-resistant sealer, waterproof cloth sheet, etc. in accordance with conventional methods. There is no problem as well.

[Other Examples]
The present invention uses the embodiment described above as a form of one basic technical idea, but the following modifications are possible.
First, what is shown in FIG. 10 is, for example, when the ceiling beam 43 is not centered in the width direction of the loading platform 1 and is biased to one side, for example, when the side surface opening unit 10 is asymmetrical in the left-right direction. For the panel 2, a hatch type ceiling panel 120 can be applied.
That is, the hatch panel 121 is pivotally connected to the wing plate ceiling base frame 11 a side of the side opening unit frame 11 at the hatch panel hinge 122, and is opened and closed by the hatch panel shift cylinder 124.
In this case, the seal sheet 127A is bonded and fixed to the base side of the hatch panel 121 as the hinge shield structure 127, and the tip shield structure 129 is the same as the tip shield structure 29 in the middle-folded ceiling panel 20. The structure of is adopted.

Further, the embodiment shown in FIG. 11 shows various modified examples of the layout of the basic configuration of the loading platform 1 including the side opening unit 10.
First, what is shown in FIG. 11 (a) is a type in which the side opening unit 10 already described is opened symmetrically, and each ceiling panel 2 is an application of the middle folding type ceiling panel 20. . Further, in the case shown in FIG. 11B, the hatch type ceiling panel 120 described above is applied to the side opening unit 10 in which the side opening unit 10 is asymmetrical and the width of the ceiling surface is smaller. The middle folding type ceiling panel 20 is applied to the side surface opening unit 10 having the larger width dimension of the ceiling surface.

  11 (c) is a type in which the ceiling panel portion of the side surface opening unit 10 is short, and this type has two ceiling beams 43 because the ceiling beam 43 is on each wing base on the loading platform structure. The book exists. The space between the two ceiling beams 43 is fixed as a part of the ceiling panel 2 of the cargo space S and does not move with the side surface opening unit 10. A half-fold type ceiling panel 20 is applied between the two ceiling beams 43.

11D shows a support member of the ceiling panel 2 in the frame 4 to which the side surface opening unit 10 is attached, that is, a lift sub-pillar 41a in the upper part of the rear arch frame 40 and a part of the front panel 6. A pillar-shaped member (not shown) is configured to be movable upward.
When the ceiling panel 2 is configured to be lifted as a whole in this way, the one shown in FIG. 11 (d) is the side opening unit 10 of the type shown in FIG. The combination with the type ceiling panel unit 20 is shown. Needless to say, the configurations of the ceiling panel 2 and the side surface opening unit 10 are not limited to the illustrated types, and may be applied to the types shown in FIGS. 11 (a) and 11 (b).
Thus, when the ceiling panel 2 is of a type that ascends as a whole, it is possible to avoid a situation in which the fork backrest portion that moves up and down in the forklift hits a part of the side opening unit 10 during cargo handling by a forklift or the like. it can.

  Furthermore, although the Example already described illustrated the type fixedly provided in the loading platform 1 of the truck T, it can apply also to a trailer type vehicle.

  In consideration of the case of transporting so-called bulk goods, a dumping specification in which the ceiling panel 2 is opened and the load B is put into the loading room S while the entire loading platform 1 can be tilted backward for taking it out is also possible. Is possible.

Furthermore, the ceiling panel 2 of the ceiling opening and closing mechanism can be used as an individual or combination of aluminum plates, waterproof sheets, resin panels, and the like.
The selection of these materials is determined in accordance with the purpose such as the case where an irregular bulk is handled as a load, the case where it is configured as a cold storage platform, and the like.
