Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a push-pull device installed in a forklift, an elevator in a ship, and the like.

[Conventional technology]

Conventionally, pallets with insertion holes into which the fork of a forklift can be inserted have been used so that cargo can be loaded, unloaded, and moved using machines such as a forklift. In order to do this, a fairly large space is required, and there was a problem that the limited storage space for luggage was narrowed down, so in recent years, thin sheet pallets have been used instead of pallets. I'm getting used to it. In correspondence with the sheet pallet, a push-pull device has been developed which is attached to a work body support such as a mast of a forklift via an attachment.

In the push-pull device described above, a pair of platens protrudes forward from the lower end of the frame connected to the work body support part of the lift of the forklift ship, and a face plate with a gripping part at the lower end for gripping the sheet pallet is mounted on the platen. It has a structure that moves the sheet pallet in the front and back direction, and it can grab the sheet pallet on which the baggage is placed and pull it in or push it out onto the platen, or it can also leave the sheet pallet on the platen and stack the baggage in a predetermined place. It has become possible to use sheet pallets to perform the same cargo handling operations as conventional pallets.

[Problem that the invention attempts to solve]

However, in the case of a forklift equipped with the above-mentioned push-pull device, since the push-pull device is configured to handle sheet pallets as described above, it is difficult to handle, for example, flexible containers containing powder-like materials. I couldn't do it. In addition, when moving or stacking flexible containers by force using a push-pull device, it is necessary to hang the container's hanging rope on a long and wide platen. There is a risk of the rope slipping or falling off, and the main body of the machine such as a forklift must be moved forward or backward when attaching or removing the hanging rope, making cargo handling operations complicated. Ta.

[Means for solving problems]

The present invention has been made in consideration of the above-mentioned conventional drawbacks, and includes a frame that is vertically movably attached to a work body support such as a forklift mast, and a frame that protrudes forward from the lower end of the frame. It consists of a pair of platens, and a face plate which is provided with a gripping part consisting of a gripper and a gripper plate at its lower part and is movable in the front and back direction on the platen by a link connected to the frame, and the gripper plate The present invention provides a push-pull device characterized in that a hook is provided on the back side of the link or at the bottom of the link, thereby solving the drawbacks of the conventional push-pull device.

[Effect]

In the present invention, a hook is provided on the back of the gripper plate or at the bottom of the link, so that a rope for hanging bag-like objects such as flexible containers can be hung on the hook.

〔Example〕

Next, the present invention will be explained in detail based on the embodiments shown in FIGS. 1 to 5.

In the figure, reference numeral 1 denotes a push-pull device, and the push-pull device 1, as shown in FIG. A pair of platens 3 protruding forward from the bottom end
and a face plate 4 supported so as to be movable in the front and rear directions on the platen 3 by a link 20 connected to the frame 2 and expanded and contracted by a hydraulic mechanism or the like. Gripper plate 50 with L-shaped cross section
A gripping portion 5 is provided which is composed of a gripper 51 and a gripper 51 and moves in the vertical direction, and the sheet pallet can be gripped by the gripping portion 5.

A reinforcing plate 6 is fixed to the back surface of the gripper plate 50 in the longitudinal direction, and a U-shaped hook 7 is fixed to the center of the reinforcing plate 6. By hanging a hanging rope a for a bag-like object such as a container, the cargo can be lifted and moved easily, reliably, and safely.

Further, as shown in FIGS. 4 and 5, the hook 7 may be fixed to the pivot point 21 on the face plate 4 side at the bottom of the link 20, or when it is fixed to the back of the gripper plate 50. Similarly, by hooking a hanging rope to the hook 7, the cargo can be lifted and moved easily, reliably, and safely.

[Effect of idea]

As explained above, according to the present invention, a hook is provided at the back of the gripper plate at the lower end of the face plate or at the bottom of the link, so that it can be easily pulled from a machine such as a forklift that can handle cargo handling using sheet pallets. Even without removing the device and replacing it with another device, the push-pull device of the present invention can lift and move cargo stored in a bag-like object with a hanging rope, improving the functionality of machines such as forklifts. can be done. In addition, the hanging rope can be attached and detached without moving the machine itself, such as a forklift, making cargo handling operations easier, and the hanging rope is securely locked to the hook, making it possible to carry out cargo handling operations safely. , which has excellent practical effects.
