Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire rope hook device for a container handling vehicle.

In general, a container cargo handling vehicle has a tilt frame mounted on the chassis of the container cargo handling vehicle so that it can be raised and raised, and the container is pulled up along the top surface of the tilt frame during loading.
In other words, when loading a container on the ground onto the tilt frame, the tilt frame is dumped, the wire rope of the winch that is pre-equipped at the front end of the tilt frame is unwound, and the hook at the end of the rope is attached to the container side. The container is hooked onto a hook, and then the winch is driven to take up the container, thereby lifting the container onto the tilt frame.

After the container is loaded in this way, the tilt frame is returned to the horizontal position, the container is transported to the destination location, the wire rope hook is removed again, and the container is lowered to the ground using, for example, a forklift.

In this way, both when loading a container and when unloading a container, it is necessary to connect or disconnect the hook at the end of the wire rope with the hook on the container side.

However, the work of connecting and disconnecting the hook at the end of the wire rope to the hook on the container side is often difficult because the wire rope is heavy or there is tension in the wire rope itself. Ta.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a wire rope hook device that allows a hook at the end of a winch wire rope to be easily and reliably connected to or detached from a hook on a container side.

In order to achieve the above object, the present invention includes a bracket that is fixed to the container side and has a receiving hole opening forward, and a bracket that is rotatably pivoted with respect to this bracket, so that a hook groove can be moved in and out of the receiving hole. The present invention is characterized by comprising a hook plate having the above structure, an operating rod projecting from the hook plate, and a lock pin penetrating the bracket from the side and being inserted into the stopper hole of the hook plate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a wire rope hook device for a container cargo handling vehicle according to the present invention will be described below with reference to the drawings.

FIG. 1 shows a cab-over type container handling vehicle. A subframe 2 is fixed on the chassis 1 of this vehicle, and a pair of brackets 3, 3 are mounted on both sides of the subframe 2 near the rear end of the vehicle. is fixed, and the vicinity of the rear end of the tilt frame 4 is pivotably supported to these brackets 3, 3 so as to be able to move up and down about a pivot pin 3a. The tilt frame 4 is given an upward and downward movement by a dump cylinder device 5 which is incorporated between the chassis 1 and the tilt frame 4 as shown in the figure.

A winch 6 is installed near the front end of the tilt frame 4, and a winding drum 7 of the winch 6 is rotationally driven by a hydraulic motor. The wire rope 8 wound on the winding drum 7 is wound around the outside of the fixed sheave 9, and then the hook fitting 10 at the tip of the wire rope 8 is attached to the front panel 12 of the container 11 by a hook device (described later). It can be connected or detached via 14.

In addition, FIG. 1 shows the poop 6 on the tilt frame 4.
The figure shows the container 11 being towed to the front end using the .

Next, attach hook 10 of wire rope 8 to container 1
The structure of the hook device 14 connected to the first side will be explained with reference to FIGS. 2 and 3.

In FIG. 2, reference numeral 15 indicates a fixed bracket fixed to the front panel 12 of the container 11, and a part of the front edge of the fixed bracket 15 is cut out to form a receiving hole 16. The frontage dimension of the receiving hole is indicated by L ₁ .

A hook plate 18 rotatable about a pivot 17 is pivotally supported on the bracket 15. A portion of the front lower edge of the hook plate 18 is hollowed out in the shape of a fishhook to form a hook groove 19. Further, an operating rod 20 is provided projecting above the hook plate 18, and a grip 21 is attached to the tip of the operating rod 20. Therefore, the grip 21 can be grasped and rotated about the pivot shaft 17 between the position shown by the solid line in the figure and the position shown by the imaginary line. The groove 19 can freely move in and out of the receiving hole 16. In addition, when the operating rod 20 is in the position shown in FIG. 2, the hook plate 18 enters into the upper part of the receiving hole 16 as shown by the solid line, and the frontage dimension at that time is indicated by _L2 in the drawing.

As shown in FIG. 3, a guide tube 22 is fixed to one side of the bracket 15 by welding, and a lock pin 23 is installed in the guide tube 22 so as to be slidable in the axial direction. A knob 24 is fixed to the rear end of this lock pin 23, and a spring 26 is connected between it and the end plate 25 of the guide tube 22.
is included. This spring 26 acts to constantly push the lock pin 23 inward. Further, a stopper hole 27 is bored in the hook plate 18, and the stopper hole 27 is slightly larger in diameter than the lock pin 23. The stopper hole 27 is bored at a position where the lock pin 23 is fitted when the hook plate 18 is in the solid line position in FIG.

In addition, in FIG. 2, the hook fitting 10 at the tip of the wire rope 8 is attached to two parallel plates 2.
8, 28, and two pins 29, 30 are installed between these plates.

Since the present invention is constructed as described above, the hook fitting 10 at the end of the wire rope 8 is attached to the hook plate 1.
When it is necessary to engage 8, use knob 2 at each end.
4 in the direction of the arrow, then grasp the grip 21 and tilt the operating stick 20 to the position. Then, the hook groove 19 of the hook plate 18 retreats as shown by the imaginary line. Therefore, since the opening of the receiving hole 16 is wide open, the hook fitting ₁ can be inserted through the opening L1.
0 pin 29 is fitted into the receiving hole 16. Then,
When the operating rod 20 is tilted upward to the position, the lock pin 23 enters the stopper hole 27 by the pressing force of the spring 26. As a result, the hook plate 18
is engaged and held while capturing the pin 29 of the hook metal fitting 10, thereby preventing the hook metal fitting 10 from coming off. Note that the frontage dimension L ₂ at this time is configured to be smaller than the diameter of the pin 29.

When it is necessary to remove the hook fitting 10 from the hook plate 18, it is sufficient to pull the knob 24 in the direction of the arrow, remove the lock pin 23, and tilt the operating rod 20 to the position.In this way, the hook fitting 10 can be easily removed. It can be measured.

As is clear from the above description, according to the present invention, a rotatable hook plate is pivotally supported on the bracket on the container side, and the hook groove of the hook plate can be moved in and out of the receiving hole of the bracket. Furthermore, since the bracket and the hook plate can be locked with a lock pin, the hook metal fitting at the end of the wire rope can be easily engaged and disengaged using the hook groove of the hook plate. In addition, it is possible to prevent the wire rope hook fitting from accidentally coming off after it has been engaged with the hook plate.
