Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention conveys ready-mixed concrete vertically to a required height and continuously and quantitatively delivers the conveyed ready-mixed concrete to a belt conveyor. The present invention relates to a fresh concrete transfer device capable of continuously and quantitatively supplying fresh concrete to a concrete driving position.

[0002]

2. Description of the Related Art Green concrete used for pouring concrete such as dams is generally considered to be a concrete with a large aggregate diameter and a poor mixture (a small amount of cement mixture).
In addition, since it is often required to transfer to a relatively high place, it is not suitable for pumping fresh concrete using a concrete pump, and in many cases, transfer using a bucket has been adopted.

[0003]

In transferring and placing ready-mixed concrete by using such a bucket using, for example, a tower crane or a cable crane,
Includes a relatively large aggregate with a diameter of 80 mm to 150 mm,
Moreover, it has the feature that it can guide and place a poorly mixed ready-mixed concrete to a high place without deteriorating its properties, but on the other hand, because the placing capacity per unit time is small, the construction period becomes longer, In addition, since the pouring interval of each concrete is wide, there is a problem in the temperature stress of the pouring concrete.

In addition, when transferring and placing fresh concrete by a bucket using such a tower crane, a special engineer such as a crane operator needs to operate the concrete.
It was necessary to secure such special engineers for a long period of time.

Further, in transferring and placing fresh concrete by using a cable crane, a lot of equipment and labor are required to stretch the cable, and further, environmental damage is required to stretch the cable. There was an inconvenience that accompanies this.

[0006] Further, the method of transporting the ready-mixed concrete by the dump truck has a feature that a large amount of the ready-mixed concrete can be transported and placed in a relatively short period of time under good placing conditions. On the other hand, when driving the dam concrete near the top of the dam where the driving surface of the dam concrete is narrowed or in the riverbed, install and prepare a cable crane, tower crane, etc. separately,
It was necessary to drive dam concrete by these conventional methods.

Further, in the construction method for transporting ready-mixed concrete by such a dump truck, for example, a dam concrete is placed in a small-scale dam whose surface for placing the dam concrete is not suitable for running the dump, or in the same manner, the dam is also placed. It was difficult to place dam concrete in sabo dams where the concrete placement surface is not suitable for running dumps.

From this point of view, when pouring dam concrete, a tower equipped with a bucket elevator is installed,
It was considered to make a dam concrete by using the bucket elevator installed in this tower.

The dam concrete pouring method using the bucket elevator, like the bucket method in the past, enables the transportation of low slump ready concrete containing large aggregates, and is of the conventional type such as tower cranes. Or, it is expected to have a feature that a large amount of fresh concrete can be transferred to the pouring position, as compared with the case of transporting fresh concrete using a cable crane.

However, in placing dam concrete using this bucket elevator, the equipment cost is relatively high, moreover, there are many movements of the driving part, and it is difficult to take it out at any position. The
Further, it is considered that maintenance cost will be significantly increased, and it is expected that a large number of buckets will need to be washed after each concrete is placed.

On the other hand, at the time of operating the bucket elevator, it is conceivable that the chain meshes with the sprocket or noise is generated due to the sliding of the bucket.

Furthermore, when the ready-mixed concrete for pouring guided by the bucket elevator is supplied to, for example, a belt conveyor provided in a boom, the supplied ready-mixed concrete is piled up on the belt of the belt conveyor. , Inconvenience that the operation of the belt conveyor is hindered is expected.

Further, when the supply amount of green concrete by the bucket elevator to the belt conveyor is reduced so as not to hinder the smooth operation of the belt conveyor, the green concrete is compared with the equipment cost and the maintenance cost. It is expected that the carrying capacity of the will be significantly reduced.

From the above point of view, the present invention is capable of continuously, quantitatively, and transferring a large amount of ready-mixed concrete to a concrete pouring position when constructing various structures such as dams, buildings and chimneys. The main object of the invention is to provide a transfer device for ready-mixed concrete, which enables continuous injection of a large amount of ready-mixed concrete.

Further, the present invention can be installed in a relatively narrow space, and further, for both concrete driving at a low position and concrete driving at a high position, continuously, quantitatively, Another purpose is to provide a transfer device for ready-mixed concrete that can transfer a large amount of ready-mixed concrete.

The present invention also provides a raw concrete transfer device capable of transferring a poorly mixed concrete having a large aggregate diameter continuously, quantitatively and in a large amount to a concrete driving position. It is one of the purposes of.

Further, according to the present invention, a device capable of continuously, quantitatively, and transferring a large amount of ready-mixed concrete to a concrete pouring position can be installed at a relatively low cost and can be operated by a special engineer. Another purpose is to provide a transfer device for ready-mixed concrete that is unnecessary and can be operated at low cost.
