Description

  The present invention relates to a container transport cart used when transporting a container for storing crops and the like, and more particularly to a container transport cart suitable for a dredging operation for transporting a crop from a field or an orchard.

  In the process of harvesting fruits such as grapes, peaches, apples, pears, and so on, it is not possible to get a truck into a field such as a field or an orchard, so the worker holds the basket in one hand and the other hand When the basket is full (usually 6-7kgs), carry it to the truck stopped on the side road of the field (usually a light truck with a maximum loading capacity of 350kgs). We are moving the harvest to the plastic container that is loaded on the

  In such a carriage by car, it is necessary to carry the truck to the truck every time the car is full. Therefore, there is a problem that the carrying distance becomes considerably large due to repeated carrying times and the work becomes heavy labor.

  In order to shorten the transport distance of the worker himself / herself, the containers are distributed in the field, the items harvested in the basket are transferred to the distributed containers, and the containers are collected when the containers are full. It is possible to carry it to a truck beside the farm. At this time, the work of transferring the harvest to the container placed on the ground is a work of bending the waist, which is also a work that causes considerable pain to the operator. In addition, a truck that transports the container is required to collect the container, but the work of transferring the container loaded on the truck to the truck bed is to remove the heavy container containing the harvest from the lower bed of the truck. It will be transshipped to a truck bed with a height of about 70 cm, which will be a heavy labor that puts a heavy burden on the arms and waist. That is, if the transport distance of the worker himself / herself is shortened, a large amount of labor is concentrated at the time of transporting and transshipping the container, and there is a problem that the work burden is increased for a weak woman or an elderly worker.

  In order to solve these problems, it is effective to use a cart with a lift. As described in Patent Documents 1 and 2 below, the prior art of a truck with a lift has an upper frame that forms a loading platform on a lower frame with wheels, and a cross-link between the lower frame and the upper frame. An elevating mechanism consisting of a jack is interposed.

  If a cart with a lift is used for the above-mentioned dredging work, even when the harvest is transferred from the basket to the container, if the container is lifted up, the work of bending the waist can be avoided and the work load can be avoided. Can be reduced. In addition, when a container is transferred from a truck to a truck bed, the container can be lifted up to the height of the truck bed so that the loading work is considerably facilitated.

  However, when the vehicle is moved in the field with a container loaded on the cart, the field scene is not necessarily flat, and the cargo may collapse during transportation. For this, it is conceivable to fix the container with a string for preventing the collapse of the load, but there is a problem that it takes time to fix the container with the string or the like and to release the lock when unloading. There is also a problem that the cart is easy to move when the container is unloaded, and the unloading operation becomes difficult.

  Furthermore, since the truck with a lift is equipped with a heavy hydraulic jack, there is a problem that the weight of the whole truck becomes large, and the burden on the work of carrying the truck itself and placing it on the truck bed is lowered.

  The present invention has been proposed to cope with such a problem, and can prevent the truck loaded with the container from collapsing, and the container can be fixed and unlocked without much trouble, and the container can be unloaded. The purpose is to be able to easily carry out the work, to easily carry the cart itself, etc., and in particular to provide a container carrying cart that can reduce the labor of unloading work. With the goal.

  In order to achieve such an object, the container transport cart of the present invention is provided with a lower frame provided with wheels and a lower frame that can be raised and lowered via a cross link, and a container for loading a container on the upper surface. An upper frame that forms a loading platform; a push handle provided on one side of the lower frame or the upper frame; and a lift jack that raises and lowers the upper frame with respect to the lower frame. A lower support portion that supports a lower portion of the upper frame, and an upper support portion that supports an upper portion of the lift jack is provided on the upper frame. A container fixing piece that protrudes above the upper surface of the upper frame at the lowered position and retracts below the upper surface by the rising of the upper frame is provided. To.

  In addition to the above-described features, the present invention is characterized in that the hand handle is provided on one side of the upper frame, and the upper support portion is provided on the hand handle.

  In addition to the above-described features, the present invention is characterized in that the lower support portion and the upper support portion removably support the lift jack.

  In addition to the above-described features, the present invention is characterized in that the lower frame is provided with a brake mechanism for fixing the wheels.

  According to the container transport cart having the above-described characteristics, the container fixing piece protrudes above the upper surface of the upper frame that forms the loading platform for container loading when the upper frame is lowered, and is placed on this upper surface. The container is held around the container by a container fixing piece, and the cart can be moved without causing collapse of the cargo. When the container is transferred from the truck to the truck, the upper frame is raised to the height of the truck bed. At this time, the container fixing piece is retracted downward from the upper surface of the upper frame. It is released naturally and containers can be quickly transferred from truck to truck.

  At this time, by adjusting the lift jack so that the floor of the truck bed and the upper surface of the upper frame are the same height, the container can be transferred to the truck bed while sliding the upper surface of the upper frame. Transshipment work can be performed easily without lifting the container. Moreover, since the brake which fixes a wheel to the lower frame is provided in this case, the transshipment work can be performed in a stable state with the wheel fixed.

  In addition, a hand handle is provided on one side of the upper frame, and the hand support handle is provided with an upper support part that supports the upper part of the lift jack, and the member for attaching the upper support part is also used as the hand handle. And manufacturing cost can be reduced.

  Furthermore, since the lower support portion and the upper support portion support the lift jack in a detachable manner, the carriage can be carried with the lift jack removed and lightened. Therefore, when the carriage is placed on the truck bed, the work for lowering the carriage from the truck bed can be easily performed.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing an overall configuration of a container transport cart according to an embodiment of the present invention, and FIG. 2 is a plan view showing an overall configuration of a container transport cart according to an embodiment of the present invention.

  A container transport cart 1 according to an embodiment of the present invention is provided with a lower frame 2 provided with wheels (front wheels 10A and 10B and rear wheels 11A and 11B), and is movable up and down via a cross link 3 with respect to the lower frame 2. An upper frame 4 that forms a loading platform for container loading on the upper surface 4A, a hand handle 5 provided on one side of the lower frame 2 or the upper frame 4, and a lift jack that moves the upper frame 4 up and down relative to the lower frame 2 6.

  In the illustrated example, the lower frame 2 is a rectangular frame, and a caster frame 11b in which front wheels 10A and 10B are supported by horizontal shafts 10a and 10b and rear wheels 11A and 11B are supported by a vertical shaft 11a. Is pivotally supported. Similarly, the upper frame 4 is a rectangular frame, and three rows of containers C are arranged on the upper surface 4A of the upper frame 4 and can be stacked and placed thereon. The container C can be stacked in a heavy box, and the stacked container C has a structure in which a bottom portion thereof can be fitted and fixed to an upper opening portion of a container below the container C.

  As shown in FIG. 3, in the cross link 3, the center of the link members 3A and 3B is pivotally supported by the shaft 3C, one end 3A1 of the link member 3A is pivotally supported by the fixed frame of the lower frame 2, and the other end 3A2 is the upper side. It is pivotally supported by a slide member 3D that slides along the frame 4. Similarly, one end of the link member 3 </ b> B is pivotally supported by the fixed frame of the upper frame 4, and the other end is pivotally supported by a slide member 3 </ b> D that slides along the lower frame 2. By means of this cross link 3, the upper frame 4 can always move up and down parallel to the lower frame 2.

  The lower frame 2 is provided with a lower support portion 7 that supports the lower portion 6A of the lift jack 6, and the upper frame 8 is provided with an upper support portion 8 that supports the upper portion 6B of the lift jack 6. The lower support part 7 consists of a saucer-shaped bracket and supports the lower end of the lower part 6A. The upper support part 8 has an opening hole 8A (see FIG. 2) into which the upper part 6B of the lift jack 6 is inserted and the upper part. It consists of a support frame that supports the flange portion of B.

  In the illustrated example, the hand handle 5 is vertically erected with a lower end fixed to one side surface of the upper frame 4, and the upper support portion 8 is provided on the hand handle 5. When the hand handle 5 is attached to the lower frame 2, it is necessary to separately provide an attachment member for attaching the upper support portion 8 to the upper frame 4.

  The lower support portion 7 removably supports the lower portion 6A of the lift jack 6, and the upper support portion 8 removably supports the upper portion 6B of the lift jack 6. Accordingly, the lift jack 6 can be detached from the cart body, and the cart body (about 40 kgs) can be carried with the heavy (about 5 kgs) lift jack 6 removed.

  For example, a manual hydraulic jack called a long stroke jack can be used as the lift jack 6, and the upper frame 4 is lifted up by extending the rod 6 </ b> E from the cylinder 6 </ b> D by repeatedly operating the lever 6 </ b> C. When descending, the valve (not shown) is opened and the upper frame 4 is lowered by its own weight. By adjusting the opening degree of the valve, the descending speed can be appropriately adjusted. Not only the hydraulic jack but also a jack made of an electric cylinder can be used.

  The other side of the lower frame 2 other than the side to which the handwheel handle 5 is attached protrudes above the upper surface of the upper frame 4 at the lowered position of the upper frame 4, and lower than the upper surface 4 </ b> A due to the upper frame 4 rising. A container fixing piece 9 is provided.

  FIG. 1A shows a state in which the upper frame 4 is at the lowest lowered position. In this state, the container fixing piece 9 provided on the lower frame 2 is above the upper surface 4A of the upper frame 4. It protrudes about 20 mm, and the container C placed on the upper surface 4A is held by this protrusion.

  FIG. 1B shows a state where the upper frame is raised to some extent. In this state, the container fixing piece 9 is retracted below the upper surface 4A of the upper frame 4, and the upper surface 4A of the upper frame 4 is removed. The container C placed on can be moved while sliding along the upper surface 4A.

  FIG. 4 is an explanatory view showing an example of a brake mechanism that can be provided in the lower frame 2. This brake mechanism fixes the front wheels 10A and 10B by pressing the brake claws 20 against the surfaces of the front wheels 10A and 10B provided in the lower frame 2. The brake claw 20 is operated by a rotation operation of an arm 21 integrated therewith, and the arm 21 biased forward by a spring 22 is pulled backward by a wire 23 to perform the rotation operation. The wire 23 can be pulled backward by depressing the foot lever 24. The foot lever 24 can be fixed at the depressed position by a locking means (not shown).

  Next, a case where such a function of the container transporting cart is used for the brewing operation will be described as an example. Here, although an example is given of the brewing operation, the application of the container transport cart of the present invention is not limited to this.

  In the dredging work (for example, harvesting and carrying out fruits in the orchard), as described above, empty containers are distributed in the field, and the basket is filled with the harvested crops in the hand-lowered basket. At that stage, it is transported to the container and transferred to the container. At this time, in the state of FIG. 1A, the containers C are arranged in a plurality of stages (three rows) on the upper surface 4A of the upper frame 4, and the rising height of the upper frame 4 is adjusted to a height at which work is easy. This makes it possible to carry out the work of reloading the harvest from the basket into the container C without bending down, and the work can be performed easily.

  When the first-stage container C is full, the upper frame 4 is once lowered to the state shown in FIG. 1A, and the container is transported while the container C is held by the container fixing piece 9 protruding above the upper surface 4A. The carriage 1 is moved to another place. At this time, since the container C is held by the action of the container fixing piece 9, the container carrying cart 1 can be moved without causing collapse of the cargo.

  When moving to another location, the empty container C is stacked on the first-stage container C, and the rising height of the upper frame is adjusted according to the height of the stacked container C. Perform transshipment work.

  When this series of operations is repeated and the container C storing the harvest is fully loaded on the upper surface 4A of the upper frame 4, the upper frame 4 is lowered to the state shown in FIG. In a state where the container C is held, the container transport cart 1 is moved to the truck on the side of the field. At this time, the container fixing piece 9 directly holds only the lowermost container C, but the containers C stacked on the container fixing piece 9 are coupled to each other by overlapping heavy boxes, so that all the containers C are held on the upper surface 4A. Thus, the container transport cart 1 can be moved without causing collapse of the cargo.

  When the container transport cart 1 is moved to the truck loading position, the brake mechanism is applied to the front wheels 10A and 10B to stop the movement of the container transport cart 1, so that the truck load height and the upper surface 4A coincide. The upper frame 4 is raised. As a result, the container fixing piece 9 naturally retreats below the upper surface 4A, so that the holding of the container C is released. In this state, the container C on the upper surface 4A is slid and transferred to the truck bed.

  As described above, when the container transport carriage 1 is used, the container fixing piece 9 protrudes above the upper surface 4A of the upper frame 4 at the lowered position of the upper frame 4, so that it is placed on the upper surface 4A. The container C is held by the container fixing piece 9, and the carriage can be moved without causing collapse of the cargo. When the container C is transshipped from the truck to the truck, the upper frame 4 is raised to the truck bed height. At this time, the container fixing piece 9 is retreated downward from the upper surface 4A of the upper frame 4. The fixing of the container C is naturally released, and the container C can be quickly transferred from the cart to the truck.

  At this time, by adjusting the lift jack 6 so that the floor surface of the truck bed and the upper surface 4A of the upper frame 4 are at the same height, the container C can be used as the truck bed while sliding on the upper surface of the upper frame 4. It is possible to transfer, and it is possible to easily perform the transshipment work without lifting the container C. At this time, since the brake mechanism for fixing the front wheels 10A and 10B is provided on the lower frame 2, it is possible to perform the transshipment work in a stable state with the carriage fixed.

  When the container transport carriage 1 is placed on the truck bed after the work is finished, the lower support portion 7 and the upper support portion 8 of the container transport cart 1 detachably support the lift jack 6. The truck can be placed on the truck bed in a state where the truck is removed and lightened. Similarly, when the truck is lowered from the truck bed, the lift jack 6 can be lowered with the truck removed from the truck body, so that the work can be performed easily.

  Further, in the container transport cart 1 in the above-described embodiment, the hand handle 5 is provided on one side of the upper frame 4, and the hand support handle 5 is provided with the upper support portion 8 that supports the upper portion 6B of the lift jack 6. Since the member to which the upper support portion 8 is attached is also used as the push handle 5, the structure can be simplified and the manufacturing cost can be reduced.
