Description

[Detailed Description of the Invention] This invention relates to an unloading device that can unload cargo such as lumber loaded onto a logging truck or the like without using any other working machine.

Conventionally, when unloading a load such as lumber loaded on a logging truck, the stake on one side of the loading platform is lowered to allow the load to fall naturally, but with this method, most of the load remains on the loading platform, making it difficult for other working machines to oppose it. It was necessary to push it out from the side.

For this reason, there were problems such as requiring a working machine for extrusion and damaging a part of the cargo by the working machine.

This invention was made with the aim of improving this problem, and is intended to provide a simple configuration of an unloading device that can unload cargo from a loading platform in a short time without using a working machine. .

This invention will be explained in detail below with reference to an illustrated embodiment.

In the figure, reference numeral 1 denotes a loading platform such as a rocking truck, which is approximately L-shaped with a deflection stake 1a erected on one side, and whose bottom portion is supported on a turntable 3 via a rotary joint 2.

On one side of the loading platform 1, the lower end side of a movable stake 4 is rotatably supported by a pin 5 located on the opposite side of the fixed stake 1a. A pulley 6 is provided supported by the.

One end of the wire 7 is fixed to the end of the movable stake 4, and a middle part of the wire 7 is bypassed around the pulley 6, and a tension spring 8 is connected to the other end of the wire 7, so that the above-mentioned possibility is achieved. The stake 4 is urged in the upright direction.

On the other hand, reference numeral 9 is a trip wire, whose middle part is pushed through an annular part 10 provided on the upper end side of the movable stake 4, and both ends are engaged with both ends of hooks 11 provided on the upper end side of the fixed stake 1a. has been done.

The hook 11 is inserted into a substantially L-shaped guide groove 1b formed on the front and rear surfaces of the fixed stake 1a, and both ends of the hook 11 protrude from the guide Jib to the outside of the fixed stake 1a.

Further, a recessed portion 1c into which the hook 11 falls is formed at the upper end of the guide groove 1b, and a substantially ■-shaped lever 12 is rotatably provided below the recessed upper portion 1c with a bent portion pivotally supported. ing.

An actuation cylinder 13 installed in the fixed stake 1a is connected to one end side of this lever 12, and by rotating the lever 12 with this actuation cylinder 13, the hook 1
1 can be pushed out from the recessed portion 1c into the guide groove 1b.

When loading onto the cargo platform 1, the movable stake 4 is held upright and the trip wire 9 is hung as shown in FIG.
Lock it to.

In this state, when loading cargo A such as lumber between each stake 1a and 4, and unloading cargo A, the actuating cylinder 13 is extended by pressure supplied through the rotary joint and the lever is rotated. Slide the hook 11 into the recessed part 1c and into the reguide groove 1.
Push out to b.

As a result, the hook 11 falls to the lower end of the guide groove 1b, and the trip wire 9, which has been under tension due to the load A, loosens, and the movable stake 4 rotates as shown in Figure 6a under the weight of the load A. At the same time, the weight of the falling load A further presses the movable stake 4 downward as shown in FIG. The load A is flipped up by the trip wire 9, and all of the load A remaining on the platform 1 is guided by the slope of the trip wire 9 and falls out of the platform 1, as shown in FIG. 6C.

After unloading, move the vehicle, use input to raise the movable stake 4 as shown in Figure 6d, and then move the guide groove 1b.
It is only necessary to engage the hook at the lower end with the recessed part 1c again, and even if the vehicle is moved without the load A on the trip wire 9, the possible stake 4 can operate the tension spring 8 independently. You don't have to worry about it falling over while driving.

As detailed above, this invention allows all the cargo on the loading platform to fall naturally by simply dropping the hook with the trip wire engaged along the guide groove during unloading.
It does not require a working machine for unloading as in the past, and the load can be unloaded in a short time without damaging the load, resulting in very high work efficiency.

Furthermore, since the configuration is simple, it can be provided at low cost, and the trip wire can be easily replaced when it wears out.
