International Publication No. WO 96/16242 and International Publication No. WO 99/11887, which are proposed and known by the present inventors and applicants. In this method, a vertically extending tower mast is installed at a construction position of a large concrete structure or a dam, etc., a boom that turns around the mast is provided on the tower mast, and a bucket elevator or the like is provided on the tower mast. In addition to providing a conveying means, the rotating boom is also provided with a conveying means such as a belt conveyer for receiving the granular material (fresh concrete) conveyed by the conveying means of the tower mast and conveying it to the end of the boom. This is a method in which a granular material (fresh concrete) is transported by a transport device provided on a mast and a boom, and is sprinkled and cast.

[0003] In this method for transferring and dispersing powdery and granular materials using a tower mast, fresh concrete or the like carried in from a fresh concrete plant is transferred upward by means of a tower mast, and further booms on a belt conveyor provided on the boom. Is transferred to the tip and sprayed. In particular, the method proposed in WO 99/11887 divides the boom into a first boom component, a second boom component and a plurality of boom components, wherein the first boom component is a tower mast. , And the second boom component is attached to the tip of the first boom component and configured to pivot horizontally, thereby increasing the pivot angle of the first and second boom components. By moving the second boom component tip along any straight line or arc,
Describes a method of distributing and pouring fresh concrete discharged from a boom component according to a set path. Further, International Publication Number WO99 / 1188
No. 7 discloses that the first and second boom components are arranged on a tracked vehicle equipped with a caterpillar or the like,
A method has also been proposed in which fresh concrete is poured into a predetermined area at an arbitrary position along an arbitrary path. That is, a first boom component that turns horizontally on the tracked vehicle is provided, and a second boom component that turns horizontally is attached to the tip of the first component, and a setting program or the like is used. A method is described in which fresh concrete is cast by program-controlling the turning angles of the first and second boom components so that the tip of the second boom component moves along a set path. .

[0004] Since a dam is usually constructed at the back of a mountain, a fresh concrete transport route to a fresh concrete placing position for dam construction includes a mountain, a valley, and a road.
There are many other obstacles. Further, during the construction of the dam, it may be difficult to transport the fresh concrete to the casting position due to the dam itself under construction.
Therefore, it is necessary to always carry out the work while securing the carry-in path.

However, when the above-described tower mast transfer device is used, the upper space where the dam is constructed can be used as a transfer path for fresh concrete. It can transport and cast fresh concrete. However, this tower transfer device has a drawback that the position at which fresh concrete can be transferred is limited to the longest circle of the boom from the tower installation position. Further, since the tower transport device becomes large, the inertia of the boom is large and it is difficult to increase the turning speed of the boom.

On the other hand, in the above-described transfer device in which a turning boom is attached to a vehicle, the inertia of the boom is not a problem because it is not large, and the driving position is not limited.
However, this vehicle must be moved to the casting position,
In addition, there is a drawback that a fresh concrete carry-in route to this position must be secured.

Delivered to 6.

The method of manually, semi-automatically and automatically controlling the tip position and speed of the second boom component 205 of the first vehicle 200 is described in International Publication No. WO 99/11887 described above.
Since it is described in detail in the official gazette, details are omitted and the outline is described.

In this embodiment, the tower transport device 10
The first vehicle 200, the second vehicle 300, and the second vehicle 300 are all configured to operate wirelessly, and have separate operation panels. This operation panel may be provided for each of the tower transport device 100, the first vehicle 200, and the second vehicle 300. Alternatively, the tower transport device 100, the first vehicle 200, the plurality of The switching operation of the second vehicle 300 may be enabled. The configuration of this operation panel is also substantially the same as that of the operation panel described in International Publication No. WO 99/11887, and the description thereof will be omitted.

When the tip position of the second boom component 205 of the first vehicle 200 is manually controlled, a stage turning drive mechanism is operated by operating an operation lever provided on the operation panel for turning the stage 203. To rotate the first and second boom components 204 and 205 as a whole, or operate an operation lever that drives a servo motor 212 for rotating the second boom component 205 and operate the turning mechanism 2.
11 is driven to rotate only the second boom component 205 to move the tip position of the second boom component 205, and to place fresh concrete in an arbitrary area.

To operate semi-automatically, the control device 214 can be operated by operating an operation lever in the X-axis direction or the Y-axis direction with respect to the XY horizontal plane on a predetermined rectangular coordinate system.
Converts a movement command in the X or Y axis direction into a turning angle of the stage 203 and the second boom component 205 and drives a stage turning drive mechanism, and a servo motor that turns the second boom component 205 212, the tip of the second boom component 205 is commanded while performing feedback control of position and speed based on a feedback signal from a pulse coder serving as a position / speed detector provided in these servomotors. It can be moved linearly in the X and Y axis directions, and the fresh concrete can be poured straight.

Further, in the case of automatic operation, when an automatic driving start command is given, the leading end of the second boom component 205 is set based on a preset program or a set path pattern and a driving area. Along the path,
Alternatively, the fresh concrete is cast by moving in the set casting area according to the set route pattern.

As described above, the fresh concrete put into the hopper 120 provided at the base of the tower mast 101 passes through the tower transport device 100 and the second vehicle 300 as a repeater, and finally as a casting device. Is transported to the driving position by the first vehicle 200 and is driven.

When the second vehicle 300 is to be cast at a position distant from the tower transfer device 100, it is sufficient to increase the number of the second vehicles 300. For a close position, fresh concrete is directly applied from the tower transfer device 100 to the first vehicle 200. It is only necessary to reduce the number of the second vehicles 300 to be received and driven or to relay from the tower transport device 100 to the first vehicle 200. Further, when the vicinity of the base of the tower mast 101 of the tower transport device 100 is to be driven, the first vehicle 200 and the second vehicle 300 are arranged in the opposite direction to that of FIG. The fresh concrete may be conveyed and cast from the lower part of the tip to the region near the base of the tower mast 101.

As described above, by increasing or decreasing the number of use of the second vehicle 300, fresh concrete can be poured into an arbitrary position and area.
There is no area limitation. In addition, the loading port for fresh concrete is provided on the hopper 12 provided at the base of the tower mast 101.
Since zero is essentially sufficient, only one port for fresh concrete is required, and the loading path is fixed, leading to a reduction in dam construction costs.

In the second vehicle 300 described above, the boom extends from the stage 303 to both sides, but a hopper extending to only one side and having a center substantially on the same line as the rotation axis of the stage 303 is attached to this boom. The structure may be provided. That is, the second boom component 2 of the first vehicle 200
It is also possible to provide a second vehicle in which a boom is constituted only by the first component 204 without the 05. The second vehicle 300
It is needless to say that the first vehicle 200 may be used as a repeater as a substitute for.

In this embodiment, the fresh concrete is lifted upward by the tower transport device 100 and transported by the boom 103 in the upper space position.
Even if there are peaks and valleys at the bottom of the tower transport device 100, there are some structures, and even if there is a part of the dam already manufactured, without being disturbed by these things,
Dam construction work can be performed, and efficient work can be performed. Moreover, in the example shown in this embodiment, since the boom of the tower transport device 100 turns around the tower mast 101, the tip position of the boom that discharges fresh concrete can be changed. Therefore, the position at which fresh concrete is discharged from the tower transport device 100 is selected as a position that does not interfere with dam construction, and fresh concrete is transferred from this position along a route (first and second vehicle arrangement positions) that does not interfere with work. It can be transported and cast. In addition, since the position of the leading end of the boom 103 and the transport path can be arbitrarily changed, an optimal position path can be selected and changed according to the degree of dam construction.

The tower transport device 100 has a hoist crane 113. This hoist crane 113
Using the to transport the members disassembled the first and second vehicles,
It can be assembled and used where needed. Further, since various members required for dam construction work and the like can be carried by the hoist crane, construction such as dam construction can be efficiently performed with the tower carrying device 100 as a center.

In the above-described embodiment, the boom 103 of the tower transfer device 100 can be turned around the tower mast 101, but may be a fixed one that does not turn. Further, a boom that expands and contracts in the longitudinal direction may be used, such as a tower transporting device disclosed in JP-A-8-209937 and International Publication No. WO96 / 16242. Also, as shown in International Publication No. WO 99/11887, the first boom component pivots around the tower mast, and the second boom component is centered on the tip of the first boom component. It may have a revolving structure.

Further, the second vehicle 30 constituting the repeater
0 also for tracked vehicle 301. Although the boom 305 turns horizontally, the tracked vehicle 301
Since the direction itself can be changed, the boom 305 may not be able to turn even in the second vehicle.

Although the first and second vehicles are capable of automatic traveling, the first and second vehicles are fixed at a predetermined position when performing the operation of transferring (casting) fresh concrete. The work is not necessarily self-propelled, and may be arranged at a predetermined position by towing by another self-propelled vehicle. Further, the vehicle may be constituted by a vehicle having wheels instead of the endless track vehicle.

The first and second vehicles are provided with a generator. However, the generator is composed of another vehicle or the like. May be supplied with power. Alternatively, only the first vehicle 200 may be provided with a generator, and the generator may supply power to the second vehicle 300 as well.

In the above-described embodiment, an example has been described in which fresh concrete is transferred and sprinkled as granules in dam construction or the like. However, as granules, besides fresh concrete, earth and sand, mud, mortar, etc. The method and apparatus for transferring and dispersing a powdery or granular material of the present invention can be used as long as the powdery or granular material is.
