本発明はプレーシングブーム本体を駆動車輪付台車に載
架し、軌条を走行させてコンクリートを打ち込みする方
決に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of placing a placing boom body on a truck with driving wheels and running the concrete on a rail.
従来、建設作業現場で使用されているプレーシングブー
ム（コンクリート輸送管付タワーとグーの構成からなり
、コンクリートを輸送するもの）は固定式であるため、
移動にあたつては■クレーン等でプレーシングブーム全
体を吊り上げるか、■全体をいくつかに分解して組み立
て直す方法がとられてきた。Conventionally, the placing boom (composed of a tower with a concrete transport pipe and a goose for transporting concrete) used at construction sites is a fixed type.
When moving, the methods used have been to either hoist the entire placing boom using a crane or the like, or disassemble the entire placing boom into several parts and reassemble them.
しかし、作業現場の立地条件や、狭隘な場所等での移動
には作業上の困難や、相当の手数を要する等の不便があ

策とならないのが現状であった。As an example of these solutions, the refractive pool can be configured to be rotatable from a vertical direction to a horizontal direction at a portion near its base, so that it can be effectively used for a wide range of concrete placement. (Japanese Unexamined Patent Publication No. 6O-47161), a switchable distribution pipe is installed in the middle of a concrete transport pipe that has multiple pumping routes, so that the placement position can be changed at will while the concrete pump is running. to improve efficiency. (Japanese Unexamined Patent Publication No. 6O-138165), however, movement is limited only to the range of the distribution pipe that has been partially expanded or pre-cented, and in the case of a position range exceeding the above two examples. Considering the above, the current situation is that no drastic measures can be taken.
これらの点に鑑みなされた本発明は、プレーシングブー
ムの下部に車軸付車輪を備え、モータ等の駆動部を車軸
に取りつけた台車上に載架し、レール上を自走できるよ
うにして従来の不便を解消しようとした方法である。The present invention was developed in view of these points, and the placing boom is equipped with a wheel with an axle at the bottom, and a drive unit such as a motor is mounted on a trolley attached to the axle so that it can run on rails. This is a method that attempts to eliminate the inconvenience of

である。To explain the present invention with reference to the drawings, FIG. 1 shows a placing boom main body in which a tower part 11 is mounted on a wheeled cart 10, and a boom part 12 is further attached to the upper part of the tower part 11.
13 is a weight placed on the trolley IO, 14 is a concrete transport pipe, and 15 is an outrigger attached to the trolley 10.
116 is a rail, 17 is a wheel, 18 is a bearing, and 19 is an axle.

16 is a rail, 17 is a wheel, 18 is a bearing, 19 is an axle, 20 is a motor attached to the truck, and 21 is a gear portion for decelerating the rotation of the motor.

The boom 12 reaches the entire location H, but does not reach locations C and D, so when working on locations C and D, the placing boom body must be moved to the left position. be. Although straight rails are shown here, it is of course possible to set the locations where movement is predicted in advance and lay the rails in a circular shape.

も本方法による採用には顕著なものがある。As mentioned above, with regard to placing booms that are used under conditions where concrete pump trucks cannot operate, there are limits to the work that is performed with fixed or movable types.
When large movements are required, it is important to be able to move easily.
In the case of the partial movement method, there are problems or limitations, and when considering the scale of the work and the conditions of the installation location, we have made it possible to increase the movement by laying rails as in the present invention. It is something. In cases where large and large movements are required, there are considerable advantages to adopting this method, considering the overall process related to concrete pouring, F: rate, labor savings, etc. There is.
