Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides construction work equipment, particularly a cart equipped with construction work equipment such as a pile driver, a crane, and an excavator, on a work frame that is movably installed at a construction site. The present invention relates to a construction work device that is mounted on a construction machine and that performs construction work by extending and hanging a part of the work machine below the side of a work platform.

Conventionally, in this type of construction work equipment, when moving the trolley from one side of the work platform to the other side, the extended hanging portion of the work equipment is first pulled up and then moved.

However, when the extended hanging part of the work equipment is pulled up above the work platform as described above, not only does the top of the work equipment on the dolly become even higher, but also its center of gravity becomes higher, making it unstable. There were problems such as not only making turning movement difficult but also dangerous.

The present invention has been made in order to solve the problems of conventional construction work equipment as described above, and its purpose is to temporarily support the extended hanging portion on the side of the work platform and then attach it to the main body of the work machine. To provide a construction work device that can safely and quickly move a truck by separating it from the work machine and moving the truck equipped with the work machine.

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3, reference numeral 1 denotes a gate-shaped work platform, such as a Goliath work machine, which runs on platform running rails 3 laid on both sides of a route 2. An inner guide rail 4 is installed at the center of the work platform 1, and an outer guide rail 5 is installed concentrically outside of the inner guide rail 4. A truck 6 is mounted on these guide rails 4 and 5, and is capable of turning movement. The truck 6 is equipped with a piling tower consisting of a stay 7, a leader 8, and the like. An attachment leader 9 is attached to a connecting portion 10 at the lower part of the leader 8.
They are detachably connected. When the attachment leader 9 is separated from the leader 8, it is temporarily fixed to the side of the work platform 1 with a pin (not shown) or the like so that it can be temporarily received.

Next, the operation of the above embodiment device will be explained.

First, the traveling device of the work platform 1 is operated to move it on the rails 3 to the construction site, and when the attachment leader 9 reaches the pile driving position, it is stopped and the traveling device is locked onto the rail 3. Install the work platform 1.

Next, the drive device of the trolley 6 is operated to rotate the trolley 6 along the guide rails 4 and 5 to the position shown by the solid line in FIG. The leader 8 is moved in the direction of the arrow in FIG. 3 by appropriate means to position it directly above the attachment leader 9. Next, the reader 8 and the attachment leader 9 are connected by the connecting part 10, and then the attachment leader 9 is connected.
from the side of work platform 1. Next, leader 8,
After setting the verticality of 9, start the necessary pile driving work.

When the pile driving work is completed, the work platform 1 is moved as appropriate along the rail 3 while maintaining the state shown in FIG. 2, and the pile driving work is successively repeated several times.

When the pile driving work on one side of the work frame 1 is completed as described above, the attachment leader 9 is fixed to the side of the frame 1 again and then separated from the leader 8, and if necessary, the stay 7 and leader 8 are temporarily removed. After retreating inward, the carriage 6 is again guided by the guide rails 4 and 5 and rotated on the pedestal 1, and set at the opposite position shown by the imaginary line in FIG. Once the trolley 6 is set, another attachment leader 9', which had been installed in advance on the opposite side of the work frame 1, is connected and the pile driving work is repeated again, and finally the pile driving work is repeated on both sides of the route 2. Carry out pile driving.

Incidentally, in the above embodiment, the cart is configured to turn and move while being guided by the guide rail, but it may be able to run and move freely without the need for a guide rail. Further, the working equipment installed on the trolley is not limited to the above-mentioned pile driving machine, but any equipment such as a crane, an excavator, etc., may be used as long as a working attachment is extended and suspended from the side of the working platform. Further, the work platform of the present invention is not limited to one on land, but may be a barge for working on a lake or river.

As described above, the present invention makes it possible to freely separate the work attachment, which is a part of a construction work machine installed on a cart movable on a work platform and extends and hangs from the side of the platform, from the work machine. Since it is provided and fixed to the side of the pedestal at the time of separation, there is an effect that the cart can be safely and reliably rotated on the work pedestal.
