Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cargo loading and unloading device for a cargo handling vehicle, which allows containers containing cargo to be loaded and unloaded onto a vehicle platform.

Conventionally, for example, as a means of transporting steel slag generated in a steel mill to a collection and processing plant, the pot body was generally loaded onto a dive car using a crane or the like, and at the collection site, the pot body was overturned along with the dump truck's cargo box. There are problems such as the fact that it takes a lot of effort to secure the pot body to the packing box.

For this reason, in recent years, special steel slag transport vehicles have been used to transport the steel slag. The steel slag transport vehicle has arms rotatably supported at the rear of both sides of the vehicle, the arms lift the pot body loaded with steel slag, and by rotating the arms back and forth, the pot body is moved to the vehicle platform. In addition to loading and unloading on top, the arm is rotated in a state where the arm and the pot body are engaged, and the pot body is turned in half to discharge the steel slag.

However, depending on the steelworks, it is not always possible to obtain a pot body that is compatible with the above-mentioned arm due to operational convenience or other reasons. In addition, in order to match the left-right spacing of the arms, the pins have to be long depending on the width of the pot body, and there is a risk that the pins will break, which may impede normal steelmaking work. Furthermore, if a pot body is manufactured that matches the left-right spacing of the arms, there are problems such as excessive weight.

This is not just limited to steel mills, but also applies to the loading and unloading and transportation of containers containing cargo in various industries.

The present invention has been made in view of these points, and includes a container framework on which a container for storing a load can be placed, and a loading/unloading means provided on a cargo handling vehicle to place the container together with the container framework onto the vehicle platform. The purpose of this is to increase the versatility of the cargo handling vehicle by allowing the cargo handling vehicle to carry out loading/unloading and transport without the need to adapt the container to the loading/unloading means described above.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments and drawings.

The arm 14.14 is rotatably supported in the longitudinal direction on a pivot 15 laterally attached to the rear of the installation base 16, and there is a space between the center of the arm 14.14 and the vehicle base 6. is provided with an arm actuating cylinder 16.16, and the arm 14.
14 is rotated back and forth around a pivot 15.

The arm 14.14 has a mounting base 13 as shown in FIG.
cam surface-shaped engagement recesses 17, 17 that open upward when the container frame 3 is oriented upwardly and are formed to engageably hold the container framework 3; Retractable locking pins j8 and 18 are provided for regulation, and the locking pins 18 and 18 are operated manually or by appropriate means such as a hydraulic cylinder.

The container framework 6 has support portions 21 and 21 erected on both sides of the base frame 20 with an interval for accommodating the container 2. On the upper surface of each support portion 21, there are support portions 21 and 21 that protrude from the container 2. A cutout hole 22 into which the lashing hanger 11 is inserted is opened, and the container 2 is suspended between the supporting portions 21 and 21, and each cutout hole 22 has a cutout hole 22 into which the lashing hanger 11 is inserted. An opening 23 is provided so as to be inclined in one direction so as not to fall off even when tilted.

On the outside of the support part 21.21, there is an engagement support member 2 located approximately in the center of the container framework 3 and engaged with the loading/unloading means 5.
5.25 is provided, and the engagement support member 25.25
Each of the side plates 26 is provided with a support shaft 27 that protrudes laterally to be engaged with the engagement recess 17, and a recess 28 into which the engagement pin 18 is fitted is provided at an appropriate position. The recess 28 is formed into an ellipse in the vertical direction in order to facilitate the insertion of the engagement pin 18.

Note that a pedestal 29 is provided on the lower surface of the base frame 20 at an interval to form an appropriate space between the base frame 20 and the installation base 13 when the base frame 20 is placed on the cargo handling vehicle 4.

Next, the effect will be explained based on the diagram.

First, the container 2 is lifted up by a crane or the like by engaging the hook 60 with the lifting hanger 10, and set on the container framework 3 (FIG. 2A). The cargo handling vehicle 4 pulls out the engagement pins 18.18 in advance to move the cargo handling vehicle 4 backward, so that the container framework 3 can freely move in and out between the arms 14.14. The arm 14.14 is rotated rearward by the operation of the engaging recess 17.1.
7 is engaged with the support shaft 27, 27 of the container frame 6.

In this case, when the container 2 is to be tilted after being transported, the openings 23 and 26 of the notch holes 22 and 22 provided at an angle in the container framework 3 are positioned toward the cargo handling vehicle 4 side.

The arm 1.4.14 is then rotated to lift the container framework 3 together with the container 2 (FIG. C). The container framework 6 is suspended together with the container 2 using the support shaft 27.27 as a fulcrum, and is maintained in a substantially horizontal state, and the arm 14.14 is further rotated to place it on the installation base 13 of the cargo handling vehicle 4. d) in the same figure, it is transported to the required location.

If the container framework 6 is to be unloaded as is, the above operation may be performed in reverse.

Next, when discharging steel slag etc. from the container 2, insert the engaging pins 18.18 provided on each arm 14. This causes the arm 14.14 to pivot rearward by actuation of the arm actuating cylinder 16.16. As a result, the container frame 3 is rotated together with the arms 14, 14, and the steel slag and the like in the container 2 are discharged by rotating to a required discharge angle A (see e in the figure). In this case, lashing of container 2/X nga 1
