Description of the Related Art In general, a container cargo handling vehicle has a dump frame pivotally supported at the rear end of a chassis so as to be tiltable rearward of a vehicle body, and is supported by the dump frame via a supporting portion so as to be rotatable in the vehicle longitudinal direction. A cargo handling frame having an L-shaped arm that can be extended and retracted on the distal end side. The cargo handling frame is rotated with respect to the dump frame in a state where the L-shaped arm is contracted and the container is moved backward on the chassis. While loading and unloading the container between the ground and the undercarriage, the container is tilted rearward on the undercarriage by tilting the cargo handling frame together with the dump frame while the L-shaped arm is extended. It is configured.

テナ傾動直後に一体的に固縛されるようにしている。When the dump frame is tilted from above the chassis, it is necessary to tilt the dump frame and the cargo handling frame together. Therefore, the dump frame and the cargo handling frame are separated from each other in the longitudinal direction of the vehicle body. A securing device that secures the frame integrally may be provided. As such a lashing device, for example, as disclosed in Japanese Patent Publication No. 54-25684, the lashing device is pivotally supported at the rear end of a cargo handling frame and swings between a lashing position and a lashing release position. A securing member which is provided at the front end of the dump frame, engages with the securing member at a securing position, and releases the engagement at a securing release position; A securing direction biasing member for biasing the binding member in the securing direction, and a securing direction biasing member provided on the undercarriage, against the urging force of the securing direction biasing member when the dump frame is lying down on the undercarriage. There has been known a device provided with a stopper which abuts on the securing member so as to restrict the movement of the securing member to the securing position. When the dump frame and the cargo handling frame are both lifted (slightly tilted) via the container during the tilting of the container in which the dump frame is tilted from above the chassis, the contact of the stopper with the securing member is released, and the securing member is released. Is quickly moved to the securing position by the securing direction urging member, so that the dump frame is integrally secured to the cargo handling frame immediately after the container tilts.

の間で積み降しされる。According to the above-mentioned structure, according to the first aspect of the present invention,
When loading / unloading the container, the L-arm is moved to the contracted state, so that the L-arm-side securing member contacting piece which moves to the rear of the vehicle body with the contraction movement of the L-arm is fixed to the guide member side. The securing member abuts against the binding member and moves to the rear of the vehicle body in the abutting state, whereby the securing member moves to the securing release position against the urging force of the securing direction urging member. I do. For this reason, the securing member is separated from the secured member on the dump frame side to enable rotation of the cargo handling frame around the support portion with respect to the dump frame, so that the dump frame and the cargo handling frame are unlocked. That is, they are separated. Thus, when the lift cylinder or the like is extended, only the cargo handling frame is tilted, and the container is loaded and unloaded between the ground and the chassis.

It is positioned at the securing position by the urging force in the securing direction by the binding direction urging member and engages with the member to be secured,
Rotation of the cargo handling frame around the support portion with respect to the dump frame is prohibited. For this reason, the dump frame and the cargo handling frame are in an integrated securing state in which the rotation around the support portion is already prohibited during the tilting operation of extending the lift cylinder and the like to tilt the dump frame and the cargo handling frame. The container tilts on the chassis due to the tilting of the dump frame and the cargo handling frame.

There is no locking delay between the two members, and the engagement of the two members is performed smoothly and reliably without interference with each other. Furthermore, since the engagement of the securing member with the secured member is performed by the urging force of the securing direction urging spring interlocking with the extension state of the L-shaped arm, a hydraulic mechanism such as a hydraulic cylinder or a control unit is used. This is unnecessary, and the securing device is inexpensive and simple in construction.

It is possible to dispose the securing member outside the moving range, and the securing member moves with respect to the cargo handling frame in a state where the movement trajectory between the securing position and the securing release position is sufficiently secured. And easy to install.

テナが地上と車台上との間で円滑に積み降しされる。Further, according to the third aspect of the present invention, when loading / unloading the container, the securing member is secured by contact with the securing member abutting piece which moves rearward as the L-shaped arm is contracted. The lashing member is positioned at the securing release position against the urging force of the direction urging member. Therefore, abutment of the securing member and the engagement member via the engagement member abutting piece is avoided, and the engagement member is moved to the engagement position by the urging force in the engagement direction by the engagement direction urging member. The container and the dump frame are engaged by the engagement device, and the container is moved between the ground and the chassis by the tilting operation around the support portion of only the cargo handling frame in the unlocked state by the securing device. It is loaded and unloaded smoothly between.

The member will position the lashing position. Therefore, the securing member and the engaging member abut via the engaging member abutting piece, and the engaging member is disengaged against the urging force in the engaging direction by the engaging direction urging member. Move to the position. Thereby, when the container is tilted, the engagement between the underframe and the dump frame by the engagement device is released, and the tilting operation between the dump frame and the cargo handling frame, which are integrally locked by the locking device, is hindered. The container is tilted smoothly on the chassis.

し、コンテナ５内の内容物が排出される。On the other hand, when the container 5 is tilted from the state shown in FIG. 6, the contraction operation of the telescopic cylinder 18 is prohibited, and the L-shaped arm 17 is held in the extended state. The securing member 24 has a securing direction so that the swing arm 29 is maintained at a swing position in which the outer end is positioned rearward of the vehicle body without contact between the swing arm 29 and the inner end of the swing arm 29. The urging spring 26 is positioned at the securing position by the urging force of the urging spring 26 and is engaged with the member 25 to be secured. The engagement between the securing member 24 and the secured member 25 causes the extension operation of the L-shaped arm 17 to continue when the container 5 is mounted on the sub-chassis 4 and swings with the securing member contact piece 31. This is performed when the contact with the inner end of the moving arm 29 is avoided. By the engagement between the securing member 24 and the secured member 25, the left and right front ends of the dump frame 12 are separated from the support shaft 13 between the dump frame 12 and the cargo handling frame 14 by the loading frame. 14 is secured to the rear of the guide member 16 by the securing device 21, and
Three turns are prohibited. As a result, the dump frame 12 and the cargo handling frame 14 are integrally secured during the tilting operation of extending the lift cylinder 19 to tilt the dump frame 12 and the cargo handling frame 14, and the dump frame as shown in FIG. The container 5 is tilted on the undercarriage 2 by tilting the container 12 and the cargo handling frame 14 backward about the pivot 11, the tailgate 7 is opened, and the contents in the container 5 are discharged.
