Description

  The present invention relates to a transportation vehicle.

  Conventionally, a transport vehicle called a bottle car has been used as a vehicle for delivering a drinking water bottle or the like from a factory to a retail store or a home. The bottle car is, for example, a small or medium truck, and a loading platform for storing a load such as a drinking water bottle is attached to the rear of the cab.

  For example, as in Patent Document 1, the loading platform has a box shape, and a slide-type side door is provided on the side surface. The load is carried in and out from this side door.

  Further, in order to increase the load storage efficiency, the loading platform divides the internal space into a plurality of loading chambers. For example, by installing a plurality of shelves in the vertical direction, the inside of the cargo bed is divided into a plurality of loading rooms. The interval between the shelves is set to an interval that gives a predetermined margin to the height of the load. By dividing the space in the loading platform into a loading chamber having a height substantially equal to the height of the load, the gap in the loading platform can be reduced.

JP 2001-171421 A

  Although the conventional loading platform has high storage efficiency, there are cases where places where it is difficult to carry in or out are generated. For example, when carrying a load into the back of the shelf at the upper stage of the loading platform or unloading a load stored in such a place, the operator may place the foot on the edge of the loading platform in an unstable state. Will be carried in and out. At this time, when the load is heavy, it becomes difficult to carry in and out because the operator loses balance. For these reasons, it is desired to develop a transport vehicle including a loading platform that can carry in and out a load more easily than in the past.

  The present invention relates to a transportation vehicle. The transport vehicle has a cargo bed. The loading platform is a shelf that extends from the loading / unloading side to the back side for loading / unloading the load, and a turn that rotates the shelf plate from a horizontal state to a state where the loading / unloading side is lowered with respect to the back side. By locking the shelf plate in a horizontal state with the moving portion, the shelf plate is kept in a horizontal state in cooperation with the rotating portion, and the locking portion is released, so that the rotating portion is rotated. And a stopper for setting the shelf board in a state where the loading / unloading side is lowered with respect to the back side.

  Moreover, in the said invention, it is suitable that the rotation angle of a shelf board is 15 degrees or more and 25 degrees or less.

  Moreover, in the said invention, it is suitable to provide the damper which brakes rotation of a shelf board when a stopper is removed.

  Moreover, in the said invention, it is suitable for the rotation part to be provided in the carrying in / out side rather than the termination | terminus part of the back | inner side of a shelf board.

  The bottom plate 18 is fixed to the chassis 14. The front plate 22, the rear plate 24, and the side plate 26 are formed so as to connect the bottom plate 18 and the ceiling plate 20, and each extend vertically from the bottom plate 18. The front plate 22 is disposed on the cab 12 side of the transport vehicle 10, and the rear plate 24 is disposed on the rear side of the vehicle.

  The side plate 26 is provided with a loading / unloading port 27 (see FIG. 3), and the loading / unloading port 27 is provided with a side door 28. The side door 28 is slidable in the longitudinal direction (X-axis direction) of the transport vehicle 10, and the loading / unloading port 27 is opened by sliding the side door 28. Further, in FIG. 1, a loading / unloading port 27 and a side door 28 are similarly provided on the side plate 26 on the hidden side.

  The rear plate 24 is provided with a rear door 30 and a tailgate (rear door) 32. The rear door 30 and the tail gate 32 are rotatable with respect to the rear plate 24, and the rear of the loading platform 16 is opened by rotating the rear door 30 and the tail gate 32.

  The internal structure of the loading platform 16 is shown in FIGS. 2 is a cross-sectional view in the XZ plane of FIG. 1, and FIG. 3 is a cross-sectional view in the XY plane of FIG. As shown in FIGS. 2 and 3, the inner space of the loading platform 16 is divided into a plurality of cargo compartments by a partition plate 34 and a shelf plate 36. The partition plate 34 and the shelf plate 36 are plate-like members formed from, for example, aluminum or stainless steel. The partition plate 34 extends vertically from the bottom plate 18 toward the ceiling plate 20 (in the Z-axis direction), and extends along the short direction (Y-axis direction) of the transport vehicle 10 as shown in FIG. ing. In the present embodiment, four partition plates 34 are provided. However, the present invention is not limited to this configuration. In consideration, an appropriate number of partition plates 34 can be provided.

  Further, the shelf plate 36 is installed in the horizontal direction between the front plate 22 and the partition plate 34 or between the partition plates 34. Here, the “horizontal direction” refers to a direction having an angle such that the load 38 does not slide and move when the load 38 is placed on the shelf board 36, and is ± 5 ° from the horizontal direction (0 °). The direction includes the range. Two shelves 36 are installed in the height direction (Z-axis direction) of the transporting vehicle 10, and thereby the loading platform 16 is partitioned into three stages of cargo compartments. In the present embodiment, the two shelf plates 36 are provided in the vertical direction. However, the present invention is not limited to this configuration, and an appropriate number of the shelf plates 36 is provided in consideration of the height of the load 38 and the height of the loading platform 16. Provided.

  Further, the distance between the bottom plate 18 and the shelf plate 36, the interval between the shelf plates 36, and the interval between the shelf plate 36 and the ceiling plate 20 are set to a height with a slight allowance with respect to the height of the load 38. It is comprised so that it may become. For example, a distance of about 5 to 10 cm is provided from the top of the load 38 to the upper shelf board 36 or the ceiling board 20.

  As shown in FIGS. 2 and 3, the partition plate 34 and the shelf plate 36 divide the space in the loading platform 16 into 25 cargo compartments. Of the 25 cargo compartments, a carriage or the like is stored in the cargo compartment provided at the rearmost of the transport vehicle 10. In addition, a load 38 is accommodated in each of the other 24 cargo compartments.

  Further, the shelf plate 36 has a square flat plate shape, and it is preferable that the length of the transport vehicle 10 in the short side direction (Y-axis direction) is equal to the length in the long side direction (X-axis direction). It is. In this case, the lengths in the X-axis direction and the Y-axis direction are determined according to the diameter of the load 38. In this embodiment, three loads 38 are stored in the X-axis direction and the Y-axis direction, respectively. It is formed to a length that can be used. That is, nine loads 38 can be placed on one shelf plate 36. Further, the thickness of the shelf board 36 is determined in consideration of the total weight of the load 38 placed on the shelf board 36. For example, when a 12 liter bottle storing drinking water is used as the load 38, a load exceeding 100 kg is applied to the shelf plate 36 on which nine 12 liter bottles are placed. The thickness of the shelf board 36 is determined so that it can bear this load. For example, when the shelf board 36 is formed of aluminum, it is preferable that the thickness of the shelf board 36 is 25 mm to 35 mm.

  Further, a guide 40 extending in the short direction (Y-axis direction) of the transport vehicle 10 is provided on the shelf board 36. The guide 40 is a member for aligning the load 38 on the shelf plate 36, and the interval between the adjacent guides 40 is determined according to the diameter of the load 38. Furthermore, as shown in FIG. 4 to be described later, a rising portion 42 is provided on the loading / unloading side of the shelf plate 36 to prevent the load 38 from jumping out.

  Next, the support structure of the shelf board 36 will be described with reference to FIG. FIG. 4 is an enlarged view when the loading platform 16 is viewed from the side. For example, when the side door 28 is opened, the operator can see the cargo bed as shown in FIG. In the present embodiment, the support structures of the lower shelf board 44 and the upper shelf board 46 are different for the two shelf boards installed in the height direction (Z-axis direction). The lower shelf plate 44 is fixed to the front plate 22 and the partition plate 34 in a horizontal state by fixing means (not shown) such as screws. On the other hand, the upper shelf plate 46 can be rotated from a horizontal state to a state where the loading / unloading side is lowered with respect to the back side of the upper shelf plate 46.

  The upper shelf 46 is supported by the rotating portion 50 at the bottom. The rotating portion 50 is located on the far side from the center when viewed from the extending direction of the upper shelf plate 46 (the direction from the loading / unloading side to the far side, the Y-axis direction in FIG. 3), and on the far side. It is provided closer to the center than the end portion 57. In this embodiment, the rotation part 50 is provided in the position of 1 / 3L from the termination | terminus part 57 with respect to the full length L of the extending direction of the shelf 46 of the upper stage.

  The rotating part 50 includes a fixed shaft 52 and an insertion part 54 through which the fixed shaft 52 is inserted. Both ends of the fixed shaft 52 are fixed to adjacent partition plates 34 and extend in the longitudinal direction (X-axis direction) of the transport vehicle 10. Further, the insertion portion 54 includes a fixing portion 56 and a housing portion 58. The fixing portion 56 is fixed to the bottom surface of the upper shelf 46 by fastening means such as screws. The housing portion 58 is a U-shaped member connected to the fixing portion 56, and the fixing shaft 52 is inserted into the housing portion 58. The insertion portion 54 is rotatable with respect to the fixed shaft 52. When the stopper 53, which will be described later, is released, the upper shelf plate 46 rotates about the fixed shaft 52 as a rotation axis, and from the horizontal state. Tilt to the state where the loading / unloading side is lowered with respect to the back side.

  Furthermore, a stopper 53 is provided on the carry-in / out side of the upper shelf plate 46 at the bottom side of the position where the rotation unit 50 is provided. The stopper 53 includes two movable shafts 55a and 55b, a spring 61, and a spring receiver 63. The movable shafts 55 a and 55 b are arranged in a straight line in the longitudinal direction (X-axis direction) of the transporting vehicle 10 and are accommodated in a casing 59 provided at the bottom of the upper shelf 46. The moving direction of the movable shafts 55a and 55b is restricted by the casing 59 only in the X-axis direction.

  Further, the movable shafts 55a and 55b are provided with projecting portions 60 extending in the Z-axis direction perpendicular to the X-axis direction in which the movable shafts 55a and 55b extend. In addition, a spring 61 is disposed around a portion from the projecting portion 60 to the inner end portion (that is, the end portion on the center side of the upper shelf 46) of the portions of the movable shafts 55a and 55b. Further, a spring receiver 63 (see FIG. 5) is provided at the bottom of the upper shelf 46 and on the extension line of the inner ends of the movable shafts 55a and 55b. In such a structure, the spring 61 is sandwiched between the protrusion 60 and the spring receiver 63.

  An engagement hole 62 is provided on the extension line of the movable shafts 55a and 55b of the partition plate 34. The outer end portions of the movable shafts 55 a and 55 b (that is, the end portions on the side surface side of the upper shelf plate 46) are inserted into the engagement holes 62 or pulled out from the engagement holes 62.

  Further, a slide handle 64 is provided at the bottom of the upper shelf 46. The movement direction of the slide handle 64 is regulated by a guide member (not shown), and slides in the Y-axis direction between the back side of the upper shelf 46 and the carry-in / out side. The slide handle 64 has a square shape and includes two sides extending in the Y-axis direction and two sides extending in the X-axis direction. Furthermore, a plate 66 is provided on the inner side of the two sides extending in the Y-axis direction and on the back side when viewed from the Y-axis direction. By pulling the slide handle 64 toward the loading / unloading side, the plate 66 comes into contact with the protrusions 60 of the movable shafts 55a and 55b.

  The movable shafts 55a and 55b and the slide handle 64 are made of, for example, aluminum or stainless steel. However, if both are made of a metal material, an unpleasant noise may be generated when the projections 60 of the movable shafts 55a and 55b and the plate 66 of the slide handle 64 come into contact with each other. Therefore, the plate 66 is made of a resin material. May be. Further, since the engagement of the stopper 53 as will be described later cannot be released when the plate 66 is worn, the plate 66 may be composed of a fixing base and a removable contact member that fixes the plate 66 to the base. In this case, the contact member may be made of a resin material.

  Further, dampers 68 are provided on both side surfaces of the upper shelf plate 46. The damper 68 may be, for example, an air damper in which air is sealed, or an oil damper in which oil is sealed. The rotation of the upper shelf plate 46 is braked by the damper 68, and the rotation width of the upper shelf plate 46 is limited to the stroke (extension / contraction width) of the damper 68.

  Further, a gutter member 70 is provided between the lower shelf plate 44 and the upper shelf plate 46 of the partition plate 34. As will be described later, the upper end of the shelf 46 can be prevented from jumping up by engaging the outer ends of the movable shafts 55a and 55b with the flange member 70.

  Next, an operation for rotating the upper shelf 46 from the horizontal state will be described with reference to FIGS. 5 and 7 show only the operation of the movable shaft 55a, the movable shaft 55b performs the same operation as the movable shaft 55a. As shown in FIG. 5, in a state where the slide handle 64 is disposed on the back side of the upper shelf plate 46, the spring 61 provided around the movable shafts 55a and 55b is formed on the protrusions 60 of the movable shafts 55a and 55b. It abuts and urges the movable shafts 55a and 55b outward (from the center side to the side surface side of the upper shelf 46). Thus, the outer end portions of the movable shafts 55a and 55b are inserted into the engagement holes 62 of the partition plate 34. At this time, the upper shelf 46 is locked by the stopper 53. This locked state is shown in FIG. In the locked state, the upper shelf board 46 is maintained in a horizontal state by the cooperation of the stopper 53 and the rotating portion 50.

  Next, as shown in FIG. 7, the slide handle 64 is slid to the loading / unloading side. As the slide handle 64 slides, the plate 66 and the protrusion 60 of the slide handle 64 come into contact with each other. The plate 66 is provided with an inclined portion that gradually increases in width. By pulling the slide handle 64 toward the loading / unloading side, the inclined portion of the plate 66 against the urging force of the spring 61 causes the protrusion 60 to move upward. Move to the center side of the shelf 46. Accordingly, the outer end portions of the movable shafts 55a and 55b are pulled out from the engagement holes 62. Thereby, the locked state of the stopper 53 is released.

  When the locked state is released, as shown in FIG. 8, the upper shelf plate 46 rotates about the rotation unit 50 as a rotation axis. At this time, the operator who slides the slide handle 64 moves the upper shelf plate 46 downward in the Z-axis direction, so that the upper shelf plate 46 is in a state where the loading / unloading side is lowered with respect to the rear side. At this time, the damper 68 brakes the rotation of the upper shelf 46 so that the upper shelf 46 is prevented from rotating suddenly. By preventing the sudden rotation, the load 38 placed on the upper shelf 46 can be prevented from dropping from the upper shelf 46.

  Further, after rotating the upper shelf plate 46, the movable shafts 55 a and 55 b are engaged with the flange member 70 provided on the partition plate 34. If the load 38 loaded on the upper shelf 46 decreases and the load on the damper 68 decreases, the restoring force of the damper 68 may cause the upper shelf 46 to jump up. Accordingly, the movable shafts 55a and 55b are locked to the flange member 70 before the load 38 is taken out, thereby preventing the upper shelf 46 from jumping up. Thereby, it is possible to work safely.

  By rotating the upper shelf 46, the loading / unloading side of the upper shelf 46 tilts downward as viewed from the vehicle height direction, so that an operator who carries out the load 38 can easily carry out the upper shelf. The load 38 loaded on 46 can be taken out. In addition, since the upper shelf 46 is inclined, the load 38 stored on the far side slides toward the loading / unloading side along the inclination of the upper shelf 46. By moving the load 38 from the back side to the loading / unloading side, the operator can easily take out the load 38.

  The upper shelf plate 46 rotates by the stroke of the damper 68 (the amount of expansion / contraction). Here, it is preferable to set the stroke of the damper 68 so that the rotation angle θ of the upper shelf plate 46 is 15 ° or more and 25 ° or less, and more preferably 20 °. If the rotation angle is smaller than 15 °, the load 38 loaded on the upper shelf 46 is less likely to slide into the loading / unloading side. Further, if the rotation angle is larger than 25 °, the inclination of the upper shelf 46 becomes steep, and the load 38 sliding on the upper shelf 46 may get over the rising portion 42 and fall from the upper shelf 46. .

  For example, when the distance from the rotation part 50 that is the center of rotation to the carry-in / out side of the upper shelf 46 is about 53 cm, the carry-in / out side of the upper shelf 46 is reduced by setting the rotation angle to 20 °. Go down 20cm. When the upper shelf 46 in the horizontal state is at an overhead position (about 180 cm) of the operator, the upper shelf 46 is lowered to the height of the face (about 160 cm) by rotation, and the work of taking out the load 38 is easy. become.

  Further, by setting the rotation angle of the upper shelf plate 46 to 25 ° or less, the load 38 packed in the back side of the upper shelf plate 46 and the ceiling plate 20 of the loading platform can be avoided, and both Collisions can be avoided. Similarly, excessive approach between the load 38 stacked at the center of the lower shelf 44 and the bottom of the upper shelf 46 is avoided, and collision between the two is avoided. In FIG. 8, if the upper shelf plate 46 is rotated, the load 38 loaded on the loading / unloading side (frontmost row) of the lower shelf plate 44 may collide with the bottom of the upper shelf plate 46. Therefore, it is preferable to rotate the upper shelf 46 after taking out the load 38 on the loading / unloading side of the lower shelf 44.

  In the above-described embodiment, only the upper shelf 46 is rotatable, but in addition to this, the lower shelf 44 may be rotatable.
