Description

[Detailed Description of the Invention] This invention relates to a container device for processing excavated earth and sand.

Conventionally, when underground pipes are buried under roads, etc., a trench is first excavated for management purposes, and the earth and sand created by the excavation is removed from the site using a transport vehicle.

Next, the underground pipe is laid in the excavated trench, and earth and sand for backfilling is brought in again to backfill the trench and then compacted, thereby completing the burial of the underground pipe.

However, the problem with the above work is the disposal of earth and sand.

In particular, loading and unloading of earth and sand at work sites with heavy traffic such as in urban areas invites traffic waves, and the earth and sand once removed from the site must be brought in again to backfill trenches, making it difficult to dispose of earth and sand. There were also some problems, such as the need for a lot of expenses.

This idea was made with the aim of improving this problem, and by providing a container device that could easily handle excavated earth and sand, it would reduce the expense required for transporting earth and sand, and it would The aim is to minimize traffic disturbances during work.

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

In the figure, reference numeral 1 denotes a cart having a plurality of casters 2 at its bottom, and a pair of fork holes 1a opening in the horizontal direction into which lifting forks 4 of a load-throwing mechanism 3, which will be described later, can be inserted and removed.

Reference numeral 5 denotes a container body that can be loaded on the cart 1, and has an open top surface, and a pair of fork holes 5a that are horizontally opened at the bottom, into which the reversing forks 6 of the load-throwing mechanism 3 can be freely inserted and removed. ing.

On the other hand, the loading mechanism 3 has a storage section 7 into which a pallet fork of a cargo handling vehicle such as a forklift truck (not shown) can be inserted and removed, and a mast 8 is provided at the front end of the storage section 7.
has been erected.

The mast 8 consists of an outer mast 8a fixed to the storage section 7 side, an inner mast 8b located inside the outer mast 8a and movable up and down by a lift cylinder 9, and a horizontal rod 8c suspended between the lower parts of the outer mast 8a. The lifting fork 4 is provided to protrude from the front surface of the inner mast 8b, and a rotation mechanism 10 is attached to the front surface of the inner mast 8b.

The rotation mechanism 10 includes a rotation support part 10a attached to the inner mast 8b side, and an annular rotation part 10b rotatably supported on the circumferential surface of the rotation support part 10a. The rotating part 10b is rotated by a drive source (not shown) provided in the rotating support part 10a.

Earth and sand excavated during underground pipe burying work, etc., is laid on a trolley 1 and stored in a movable container body 5. Some of it is stocked near the site for backfilling, and the rest is transported. Transported from the site by vehicle.

For unloading, the tip of the lifting fork 4 of the loading mechanism 3 installed on the cargo handling vehicle was inserted into the fork hole 1a of the cart 1, and the tip of the reversing fork 6 was inserted into the fork hole 5a of the container body 5. After that, the inner mast 8b is raised by the lift cylinder 9, and only the container body 5 is raised to the height of the loading platform of the transport vehicle, as shown in FIG.
All you have to do is load it onto a loading platform and transport it from the site.

In order to backfill the trench after the installation of the underground pipe is completed, the earth and sand previously stocked in the container body 5 for backfilling is moved to the vicinity of the trench by the trolley 1, and then the lifting fork 4
into the fork hole 1a of the truck 1, and then the reversing fork 6
are inserted into the fork holes 5a of the container body 5, and only the container body 5 is raised to a predetermined height, and then the container body 5 is rotated by the rotation mechanism 10, and the earth and sand accommodated in the container body 5 are All you have to do is throw it into the trench and backfill it.

On the other hand, when both the truck 1 and the container body 5 are loaded on a transport vehicle and moved around the site, the lifting fork 4 is inserted into the fork hole 1a of the truck 1, and the reversing fork 6 is inserted into the fork hole 5a of the container body 5. With the pallet fork (not shown) inserted into the storage section 7, the entire loading mechanism 3 is raised to the height of the loading platform of the transport vehicle and loaded onto the loading platform.

As detailed above, this idea involves storing a portion of the excavated earth and sand in the container body for backfilling and storing it near the site, so the amount of earth and sand to be carried out is significantly greater than with conventional construction methods. In addition, there is no need to transport earth and sand for backfilling using a transport vehicle, which significantly reduces the cost of transporting earth and sand, and also minimizes traffic disturbances during construction work in urban areas. Can be done.

In addition, since the earth and sand are stored and treated in the container body,
The soil stocked for backfilling is less likely to be scattered, and the soil inside the container body can be thrown into trenches by reversing the container body using a rotating mechanism during backfilling, making backfilling work easy and efficient. be able to.
