JPS5893634A - Tension releasing device for wire rope in container cargo handling vehicle - Google Patents

Abstract

PURPOSE:To loosen easily a wire rope on a tension, by a method wherein a latch plate provided with a hook groove and a lock groove on its circumference is hinged on a bracket and free taking in and out of a lock arm to or from the lock groove of the latch plate is allowed. CONSTITUTION:When a lever 27 is turned to a position A at the time of traction of a container by a wire rope for piling up, a roller 30 of a lock arm 26 enters into a lock groove 19 of a latch plate 17. The latch plate 17 is held at a position where it hits against a stopper 24. When a pin 37 of hook metal fittings on the tip of the wire rope 8 is connected with the hook groove of the latch plate 17 and the wire rope 8 is pulled under this state the container can be pulled by a winch. To release a tension state of the wire rope 8, turn the lever 27 to a position B, then the roller 30 comes off from the lock groove 19, through which control of the plate 17 is released and tension of the wire rope 8 released.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire rope tension release 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 as to be able to be lifted up and down, 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, and the winch installed at the front end of the tilt frame unwinds with a wire rope, and the hook at the end of the rope is placed on the container side. The container is hooked onto the hook, and then the winch is driven to take up the container and pull it up onto the tilt frame.

After the container is loaded in this way, the tilt frame is returned to the horizontal position and the container is transported to the destination location, but a forklift may be used to unload the container at the site.

At this time, it is necessary to remove the footer at the end of the winch's wire lobes, but there is a problem in that the lobes are normally in a tensioned state, making it difficult to remove the hook.

Therefore, one object of the present invention is to provide a wire rope tension release device for a container cargo handling vehicle, which uses a winch's wire lobe to tow and load a container, put it in a tensioned state, and easily loosen the wire rope. There is a particular thing.

In order to achieve the above object, the device according to the present invention includes a bracket fixed to a container, a latch plate rotatably supported on the bracket and provided with a hook port and a lock groove on the periphery. The latch plate is rotatably mounted to the bracket and has a lock foot that can be moved in and out of the lock groove of the latch plate.

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

Figure 1 shows a cab-over type cargo handling vehicle, with a subframe fixed to the top of the vehicle's chassis, and a pair of brackets on both sides of the subframe near the rear end of the vehicle. ),? , j are fixed, and near the rear end of the tilt frame is pivotably supported with respect to these plaquettes J and J so as to be able to move up and down about a pivot pin Ja. The tilt 7-frame bow can be moved up and down by a dump cylinder device I installed between the chassis I and the tilt frame bow as shown in the figure.

A winch base is installed near the front end of the tilt 7 frame shaft, and the winch 6 has a winding drum γ driven to rotate by a hydraulic motor. Above fist WA? The wire rope t wound above is wound around the outside of the fixed sheep 9, and then the 7 hooks 10 at the tip of the wire loop t are connected to the front panel saw of the container 1 through tension release @ 10, which will be described later. It is designed so that it can be locked.

In addition, Fig. 1 shows a state in which the container /l is towed to the frontmost end using the winch base on the tilt frame, and in this state, the winding drum t of the winch 6 and the container /l are pulled together.
The wire loop t connecting the wires 1 and 1 is under tension.

Next, release the tension on the wire rope t.
The configuration of 41 will be explained with reference to FIG.

In FIG. 1, the reference numeral /S designates a fixing bracket fixed on the front panel l of the container l, and this bracket lI consists of two parallel plates. A latch plate rotatable about a pivot 14 is pivotally attached to the fixed bracket)/j. A hook mat and a lock groove 19 are formed on the periphery of this latch #1. Also, the protrusion of the latch plate 17! A spring n is hooked between / and the cross beam n, and the latch plate l is urged to rotate in the direction of the hour hand in the figure. The maximum rotational position of the latch plate I in the clockwise direction is regulated by a stopper tab.

On the other hand, a p-tsuk arm that can be rotated about a pivot is pivotally supported on the fixed bracket /j, and an operating lever protrudes from this lock arm roller, and a g9yp-X is attached to the tip of the lock arm. It is installed.

A roller rotatable around -M is pivotally supported at the tip of the lock arm. When the roller J0 is locked, the latch IF1 has a groove l! It allows you to go inside.

Further, a spring J/ is provided between the operating lever J7 and the front panel saw, and the maximum clockwise position of the operating lever is regulated by a stopper.

On the other hand, a hook fitting J is provided at the tip of the wire robe I. This hook metal fitting 341 is made of parallel link plates 36, 3! It consists of one bin 36.3 placed at a distance from t, and the bin 36.
A wire loop t is connected to the pin 3 so that the pin 3 engages with the hook groove /1 of the latch plate 17.

Next, the mode of use of the wire lobe tension release device described above will be explained.

First, when it is necessary to index the containers // with the wire rope I of winch 4 in order to stack them on the tilt frame, grip the grip It rotates until it is still in contact with the rotation stopper. Then, the roller V at the end of the lock arm is connected to the latch plate/lock groove of the soil/? In this state, the latch plate 170 is held in a position in contact with the stopper, and the clockwise rotation of the latch plate 170 is restricted. In this state, the bottle 3 of the hook metal fitting 34 at the end of the lie 5 and the robe l is locked to the hook #4/j of the latch plate l as shown. By driving the winch and pulling the wire lobe S in this state, the container // can be towed by the winch.

Next, when trying to release the tensioned state of the wire lobe t, the operation lever J? Grasp the grip X and rotate the control lever counterclockwise around the pivot
Lower it to the ■ position shown by the chain line in the figure.

Then, the roller 30 at the tip of the lock arm becomes a latch latch.
It will come out to the outside from the lock groove l.

Then, since the restriction on the latch plate is released, the tension of the wire lobe i causes the latch plate 17 to rotate counterclockwise on the hook metal part 1, and the tension on the wire lobe is released. . Therefore, the wire lobes t can be easily removed from the hook fitting 3'l at the end, and the connection between the container // and the wire lobes t can be broken very easily.

As is clear from *q above, according to the present invention, the rotation of the latch plate that crushes the tip of the wire lobe is restricted during towing, and when the wire lobe tension is released, the lock arm is moved into the lock groove of the latch plate. It can be moved in and out, making it easy to release tension from the wire robe.
