Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cargo handling vehicle used for loading and unloading luggage into and from a large container with one-way opening, for example.

[0002]

[Prior Art]

 Currently, there is no dedicated machine for loading and unloading large, heavy items that are full of space and are large in size, such as sea containers. For this reason, luggage is currently taken in and out by using rollers or sliding the floor. However, since such a method requires so-called human power to load and unload, it is troublesome and dangerous.

[0003]

[Problems to be solved by the device]

 The present invention was devised in order to solve this problem in view of the above-mentioned problems, and the purpose thereof is to save a lot of time for loading and unloading luggage into a container, etc. The purpose is to provide a cargo handling vehicle that is capable of working.

[0004]

[Means for Solving the Problems]

 The cargo handling vehicle of the present invention is basically a front vehicle body, a rear vehicle body that is bendably provided on the rear side of the front vehicle body and is inserted under the eaves of a pallet, and a front vehicle body that is independently rotated right and left. It is characterized in that it is composed of a front wheel that is driven, a rear wheel that is provided on the rear side of the rear vehicle body, and an elevating device that is provided on the rear vehicle body and that raises and lowers the pallet.

[0005]

[Action]

 Luggage is loaded on the pallet. When loading a pallet into a cargo-handling vehicle, the rear vehicle body is inserted under the eaves of the pallet, and the pallet is lifted by the lifting device and then taken off. When carrying a pallet loaded in a cargo handling vehicle, the front wheels are driven to rotate and the cargo handling vehicle travels. When moving a cargo-handling vehicle straight, rotate the left and right front wheels at the same speed. When the cargo handling vehicle is turned, the left and right front wheels are rotated at different speeds. Then, the front vehicle body and the rear vehicle body are bent toward the slower rotation speed and are diverted in the same direction. When pallets are unloaded from a cargo handling vehicle, the procedure is the reverse of loading.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing a cargo handling vehicle according to an embodiment of the present invention. FIG. 2 is a plan view of FIG. 1. FIG. 3 is a schematic side view showing a state where the cargo handling vehicle is used in the container. The cargo handling vehicle 1 is mainly composed of a front vehicle body 2, a rear vehicle body 3, a front wheel 4, a rear wheel 5, and an elevating device 6, and in this example, three pallets are placed in a container C that is 40 feet open on one side. The luggage W loaded on P is taken in and out. The front vehicle body 2 forms a basic part of the cargo handling vehicle 1. In this example, a driver's cab 7 is provided. The rear vehicle body 3 is provided on the rear side of the front vehicle body 2 so as to be bendable and is inserted into the eaves Q of the pallet P. In this example, the main body 8 and the left and right parts extending rearward from the lower part It is composed of an arm 9 and a connecting device 10 for detachably connecting them, has a substantially L-shaped side surface, and is of a so-called articulate type depending on the front vehicle body 2. The front side of the main body 8 is pivotally connected to the rear side of the rear vehicle body 3 via a turning shaft 11. Each arm 9 has a sheath-fork shape and is integrated through front and rear and X-shaped connecting members 12, and is inserted into the eaves Q of the pallet P. Each connecting device 10 includes a left and right connecting piece 13 having a bifurcated shape protruding from the rear side of the main body 8, and a connecting hole 14 (a hollow arm 9 formed on the front side of the arm 9 into which the connecting piece 13 is inserted. The inner front side is utilized.), A pair of front and rear lateral holes 15 formed over the connecting piece 13 and the arm 9, and a pin 16 detachably inserted into these. . The pallet P is a single-sided pallet or a skid on which a load W is loaded and the lower eaves Q are opened. The front wheels 4 are provided on the front vehicle body 2 and are driven to rotate independently left and right. In this example, the two front wheels 4 are provided on the front vehicle body 2 so as to be rotatable, and are not shown. The left and right hydraulic drive units (HST) driven by the prime mover are independently driven to rotate, which is a so-called skid steer type. The rear wheels 5 are provided on the rear side of the rear vehicle body 3, and in this example, four rear wheels 5 are provided rotatably on the lower rear side of each arm 9 for a total of eight wheels. The elevating device 6 is provided on the rear vehicle body 3 to elevate and lower the pallet P. In this example, the elevating device 6 is a total of four lift cylinders provided before and after each arm 9, and the front one is especially It is designed so as not to interfere with the coupling device 10. That is, the connecting piece 13 of the connecting device 10 is bifurcated so as not to interfere with the lift cylinder. Next, the operation will be described based on such a configuration. Loads W are loaded on the pallet P. When loading the pallet P onto the cargo handling vehicle 1, after the arm 9 of the rear vehicle body 3 is inserted under the eaves Q of the pallet P, the four lift cylinders, which are the lifting devices 6, are extended synchronously, so that the pallet P is loaded. Is lifted and taken off. When carrying the pallets P loaded on the cargo handling vehicle 1, the front wheels 4 are rotationally driven to drive the cargo handling vehicle 1. When moving the cargo handling vehicle 1 straight ahead, the left and right front wheels 4 are rotated at the same speed. When the cargo handling vehicle 1 is turned, the left and right front wheels 4 are rotated at different speeds. Then, the front vehicle body 2 and the rear vehicle body 3 are bent toward the slower rotation speed and are diverted in the same direction. When pallets P are unloaded from the cargo handling vehicle 1, the procedure is the reverse of loading. Since the front body 2 and the rear body 3 of the cargo handling vehicle 1 are so-called articulate type, the turning loci of the front wheels 4 and the rear wheels 5 are substantially the same, and the turning radius can be reduced. In the cargo handling vehicle 1, since the front vehicle body 2 and the rear vehicle body 3 are so-called articulate type and the front wheels 4 are so-called skid steer type, the steering cylinder can be omitted. Since the main body 8 of the rear vehicle body 3 and the arm 9 are detachably connected by the connecting device 10, the length of the arm 9 can be changed to a different one, and the length of the luggage W and the pallet P can be changed. Can respond to it.

Although the cargo handling vehicle 1 loads and unloads the luggage W into and from the container C in the previous embodiment, the invention is not limited to this. Although the arm 9 of the rear vehicle body 3 can be attached to and detached from the main body 8 in the previous embodiment, the present invention is not limited to this, and these arms may be integral with each other and non-attachable. Although the rear vehicle body 3 is provided with the left and right arms 9 in the previous embodiment, the present invention is not limited to this, and these may be replaced by platforms, for example. Although the lifting device 6 is four lift cylinders in the above embodiment, the lifting device 6 is not limited to this, and may be, for example, a lift table or the like that is lifted by a lift cylinder.

[0008]

[Effect of the device]

 As described above, according to the present invention, the following excellent effects can be obtained. (1) The front body, the rear body, the front wheels, the rear wheels, and the lifting device are configured so that they can be loaded and unloaded by the so-called mechanical force, so it does not take much time to load and unload luggage into and from containers. You can work safely. (2) Since the front vehicle body and the rear vehicle body can be bent, and the front wheels are independently driven to rotate left and right, the turning radius can be reduced and the steering cylinder can be omitted.
