Field of the Invention The present invention relates to a crane device for hanging a transport container, which is provided with a detent mechanism on a hook body connected by means of a hook. 2. Description of the Related Art Conventionally, as a transport container for storing earth and sand, a bottom plate of the transport container is provided so as to be openable and closable. There is one that opens the bottom plate to let the earth and sand fall. As a technique for suspending this type of transport container,
For example, one disclosed in Japanese Utility Model Laid-Open No. 49-64958 is known. In this method, a guide fitting is provided below the hook body of the crane boom, a wire connected to the bottom plate of the transport container is connected to the guide fitting, and the bottom plate is opened by lowering and loosening the guide fitting. I have. However, in the above-mentioned prior art, when the transport container is hung by the crane boom, the hook body rotates left and right, and the transport container also rotates accordingly. There was a problem. The present invention has been made in view of the above-described problems of the related art, and has a crane device for hanging a transport container that can prevent rotation of a hook body and a transport container during a suspending operation of the transport container. Is to provide. According to the present invention, there is provided a crane apparatus for suspending a transport container having an openable and closable bottom plate, in addition to a wire for suspending the transport container. An opening and closing wire that opens and closes the bottom plate is provided,
The opening / closing wire is suspended from the hook body, the detent holding member is fixed to the hook body, and the hanging wire is inserted through the wire insertion portion of the detent holding member. [0005] A crane device for transporting containers according to the present invention is used for civil engineering, construction, ships, manufacturing factories, and the like. The transport container hanging crane apparatus includes a suspending wire, and the suspending wire suspends a transport container provided with an openable / closable bottom plate (opening / closing door). The transport container is
It is a box-shaped or cylindrical container mainly having an upper end opening, and accommodates an object in a state where the transport container is lowered or hung on the ground. Objects contained in the transport container include earth and sand,
Examples include waste, product materials, agricultural products, marine products, minerals, and the like, and the physical state thereof is not limited to solid or liquid. The crane beam, which is the main body of the crane device for transporting container suspension, includes a hook main body that supports an opening / closing wire connected to the bottom plate,
A hook support wire and a transport container lifting wire are provided. The supporting wire supports a hook main body (a pulley block) having a hook portion, and fixes a rotation preventing holding member in a horizontal direction on an upper portion of the hook main body. An O-shaped or C-shaped ring-shaped wire insertion portion is provided at a distal end portion of the detent holding member. A lifting wire is inserted through the wire insertion portion. This enhances the mutual binding force between the lifting wire and the hook body. In the above configuration, to close the openable bottom plate of the transport container, the open / close wire may be pulled up by lifting the hook body with the hook support wire. Then, the bottom plate turns upward and closes due to the pulling force of the opening / closing wire. Conversely, to open the bottom plate, the tension of the opening / closing wire may be reduced by lowering the hook body with the support wire. Then
The bottom plate pivots downward and opens. In the present invention, the detent holding member is fixed to the hook main body in the lateral direction, and the container lifting wire is inserted downward through the wire insertion portion on the distal end side of the detent holding member. In this case, in a state where the lifting wire is inserted through the wire insertion portion, the load load G of the transport container acts on the hook body via the pulling force of the opening / closing wire, and a strong force is applied between the wire insertion portion and the lifting wire. An interlocking force occurs. For this reason, even if a large rotational force around the guide shaft is applied to the hook body during the suspension operation of the transport container, the rotation of the hook body is prevented. Therefore, it is possible to reliably prevent the hook body and the transport container from suddenly turning left and right during the hanging operation. Next, an embodiment of the present invention will be described with reference to an embodiment shown in the drawings. In the present embodiment, a movable container (hook body) and a hook portion are supported by a support wire in a transport container suspension crane device to which a block (hook) support wire and a container (transport container) lifting wire are attached. The detent holding member is fixed to the upper part of the movable block in the horizontal direction, and a wire insertion ring (wire insertion part) is provided at the tip of the detent holding member, and the lifting wire is inserted through this ring to lift the lifting member. The restraining force between the wire and the movable block is increased to prevent the movable block and the hook from turning.

Reference numeral 11 denotes a horizontal bar. The lower end of a bar holding wire 13 is connected to the center of the horizontal bar 11. The upper end of the bar holding wire 13 is locked by the hook 2. At the left and right ends of the horizontal bar 11, the upper ends of two sets of opening / closing wires 15, 16 of which two are one pair (pair) are fixed, and the lower ends of the opening / closing wires 15, 16 of each set are:
The box-shaped container 9 extends along the front side and the back side.
The lower ends of the opening / closing wires 15 and 16 pass through a pair of left and right narrow wire holding brackets 22 and 23 and a wide wire holding bracket 24 provided on the front side and the back side of the box-shaped container 9. The narrow wire holding brackets 22 and 23 and the wide wire holding bracket 24 are formed in a U-shape,
Horizontal (horizontal) at the top and middle of the box-shaped container 9
Attached to. In the present embodiment, a roller is attached to the wire abutting portion of the wire holding fittings 22, 23, 24, and the opening and closing wires 15, 1
6 is smoothly guided. A plate-shaped or rod-shaped U-shaped hanging rod 10 is attached to an upper central portion of the box-shaped container 9, and a lower mounting portion of the hanging rod 10 is swingably connected to a horizontal shaft 14. A wire 18 extending to one side (the left side in FIG. 1) of the box-shaped container 9 is connected to a horizontal upper portion of the hanging rod 10.
A weight 19 is connected to the lower end of 8. The weight 19 is fitted so as to be able to move up and down along a guide shaft 17 parallel to one side surface of the housing box-shaped container 9. For this reason, the hanging rod 10 is
Due to its own weight, the box-shaped container 9 is constantly urged downward in one direction. Reference numerals 20 and 21 denote a pair of left and right opening / closing gates, which constitute the lower bottom portion of the box-shaped container 9. Opening gate 2
The outer ends of 0 and 21 are hinged to the lower edge of the box-shaped container 9 via hinges 12, and the lower ends of the open / close wires 15 and 16 are connected to the inner ends of the open / close gates 20 and 21. ing. Thereby, the opening / closing gates 20 and 21 are attached to the box-shaped container 9 so as to be openable and closable up and down, and the opening / closing gates 20 and 21 can be opened by pulling the opening / closing wires 15 and 16 upward. Next, the operation of the present invention will be described. In the transport container hanging crane device, when storing and loading earth and sand in the box-shaped container 9, first, the open / close gates 20 and 21 of the box-shaped container 9 are closed. Opening gate 20, 2
1 is closed while the box-shaped container 9 is lifted. That is, in FIG. 1, the pair of opening / closing wires 15 and 16 at both ends of the horizontal bar 11 are pulled up by gradually lifting the hook portion 2 of the movable block 5 by the block supporting wire 3. Then, by the pulling force of the pair of opening / closing wires 15, 16, the opening / closing gate 20,
21 pivots upward around the hinge 12 inside the box-shaped container 9, and the open / close gates 20, 21 are completely closed. When the gate is closed, the weight 19 moves to the upper end of the guide shaft 17 via the wire 18 as shown in FIGS. Thereafter, earth and sand are stored and loaded in the box-shaped container 9 while the box-shaped container 9 is suspended. After storing and loading the earth and sand in the box-shaped container 9, the box-shaped container 9 is moved to a target carrying place, and the opening and closing gates 20 and 21 are opened to drop the earth and sand while the box-shaped container 9 is lifted. In this case, in order to open the opening / closing gates 20 and 21, the tension of the pair of opening / closing wires 15 and 16 is relaxed by gradually lowering the hook 2 of the movable block 5 with the support wire 3. Then, the loosening of the opening / closing wires 15, 16 causes the opening / closing gates 20, 21 to pivot below the box-shaped container 9 around the hinge 12 as shown in FIGS.
1 is completely open. Next, after all the earth and sand is dropped from the box-shaped container 9, the box-shaped container 9 is moved again to the earth and sand loading place to newly store and load the earth and sand. When storing and loading earth and sand, the opening and closing gates 20 and 21 are completely closed as described above. That is, while the box-shaped container 9 is being lifted, the tension of the pair of opening / closing wires 15 and 16 is increased by lifting the hook portion 2 with the support wire 3. Then, the opening / closing gates 20 and 21 rotate upward around the hinge 12 inside the box-shaped container 9, and the opening / closing gates 20 and 21 are completely closed. When the opening / closing gates 20 and 21 are closed, the container lifting wire 4 is pulled down to bring the box-shaped container 9 into contact with the ground. After the grounding, the lifting wire 4 is further pulled down to release the pulling force on the hanging rod 10. Then, as shown by imaginary lines in FIGS. 5 and 6,
The hanging rod 10 is pulled obliquely downward by the weight 19 to 90
The hanging rod 10 tilts to the side of the box-shaped container 9 horizontally. Thereby, the box-shaped container 9
Of the box-shaped container 9 because the upper opening of the
It becomes possible to easily carry out the work of storing and loading the earth and sand into the yard. After that, when the earth and sand are stored and loaded in the box-shaped container 9, a predetermined amount of earth and sand can be transported to a target place by repeating the above-described operation procedure. In loading and unloading earth and sand using the box-shaped container 9, a force for rotating the movable block 5 acts on the block support wire 3. However, in this embodiment, the movable block 5 does not rotate. That is, since the container lifting wire 4 is inserted through the ring 7 of the detent holding member 6 connected to the movable block 5, the load G (about 4.5) of the box-shaped container 9 within the width W of the moving pulley 8.
Tongue), a strong locking force is generated between the ring 7 and the lifting wire 4, and the movable block 5 and the hook portion 2 do not rotate left and right around the guide shaft. Although the above embodiment has been described above, the present invention can be applied to various modifications. For example, hanging rod 1
For 0, a rectangular member other than a plate or a rod may be used, and the lower end of the hanging rod 10 may not be configured to be swingable with respect to the upper part of the box-shaped container 9. In this case, it is preferable that the height of the hanging rod 10 is set to be longer than a predetermined value so that the presence of the hanging rod 10 does not hinder the sediment storage and loading operation. As described above, according to the present invention, the detent holding member is fixed to the hook body, and a wire insertion portion through which the hanging wire is inserted is formed at the tip of the detent holding member. As a result, a mutual restraining force is generated between the hanging wire and the hook main body, so that there is an excellent effect that the hook main body and the transport container can be reliably prevented from rotating during the crane operation.
