Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for disassembling and transporting a large crawler type pile driver.

[Conventional technology]

When transporting a large pile driver, it is essential to remove the crawler from the pile driver and load it due to the load limit of the transport trailer.In the past, it was necessary to lift the pile driver using a special jack and remove the crawler. Alternatively, for stability during work, use the front jack and outrigger jack provided on the pile driver to lift the pile driver and remove the crawler, then pull in the transport trailer and mount it. , but later,
As shown in Japanese Patent Application Laid-Open No. 58-167'387,
Each jack was removed.

[Problem to be solved by the invention]

For this reason, disassembly and loading work took time and was inefficient.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a disassembly and transportation method that can improve the efficiency and safety of disassembling and transporting a large pile driver.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a method for disassembling and transporting a large pile driver, in which arms equipped with front jacks are provided on both sides of the leader bracket so as to be openable and closable, and arms equipped with outrigger jacks are provided on the rear left and right sides of the upper revolving body. is installed so that it can be folded toward the rear of the vehicle body, and crawlers on both sides of the truck frame are installed at the bottom of the upper revolving body so that it can be rotated.
Follow the steps (1) to (3) below to load the blade onto the transport vehicle.

(1) Extend the front jack and outrigger jack to ground the crawler, extend the crawler extension cylinder to remove the crawler from the truck frame, and then retract each jack to remove the bottom surface of the truck frame. Ground it.

(2) Expand the arms of the front jacks beyond the width of the transport vehicle, extend the front jacks and outrigger jacks to lift the lower surface of the truck frame above the vehicle height of the transport vehicle, and turn the truck frame 90 degrees. do.

(8) Pull the transport vehicle into the space under the truck frame,
Each jack is deflated and mounted on the loading platform of a transport vehicle, and the front jack and outrigger jack are stored within the width of the vehicle body.

[For production]

Therefore, a large pile driver can be equipped with a self-blade on a transport vehicle by using the front jack and outrigger jack, and each jack can be folded and transported as is.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The large pile driver 1 has an upper rotating body 3 on the upper part of the lower traveling body 2.
The leader 5, which is erected on the leader bracket 4 at the front of the upper revolving body 3, is connected to two backstays 6 and 6.
It is supported by

On both sides of the leader bracket 4, arms 8, 8 each having a front jack 7 are provided, each pivotally supported by a bin 9, so as to be able to open and close from side to side.
Arms 11. each are equipped with outrigger jacks 10 on the rear left and right sides. ．． 1.1 are respectively pivotally supported by the bins 2 and are provided so as to be foldable toward the rear of the vehicle body. During work, the arms 11.11 are horizontally rotated to attach to the bins 13. It is fixed and extends from the left and right sides of the vehicle body, and when moving, the bin 13 is removed and rotated to the rear of the vehicle body to fold it.

The lower traveling body 2 is provided with crawlers 15 and 15 on both sides of a track frame 14 which is rotatably connected to the upper rotating body 3 so as to be expandable and retractable in the vehicle width direction by crawler expansion and contraction cylinders 16.

Next, a method for disassembling and transporting the large pile driver 1 configured as described above will be explained.

First, as shown in FIG. 4, after removing the leader 5, backstay 6.6, and counterweight 7 from the upper revolving body 3, the front jack 77 and outrigger jack 10.10 are each extended. Crawler 15,1
．． 5 and extend the crawler telescoping cylinders 16 as shown in FIG.
5 from the truck frame 14, and as shown in FIG. 5, the front jacks 7.7 and outrigger jacks 10.10 are contracted to ground the lower surface of the truck frame 14.

Next, as shown in FIG.
．． The arms 8, 8 of 7 are expanded wider than the width of the transport vehicle 18, and as shown in FIG. Tsuki 77 and Outrigga Jatsuki 10.1
0 is extended to raise the lower surface of the truck frame 14 to a level higher than the vehicle height of the carrier vehicle 18, and the truck frame 14 is turned 90 degrees using a turning mechanism to fit the truck frame 14 within the vehicle width.

In addition, the front jack is 7.7 and the outrigger jack is 10.
．． If the stroke of 10 is long and the lower surface of the truck frame 14 can be raised above the vehicle height of the transport vehicle 18, use the front jack 7°7 and the outrigger jack 10.
．． It is not necessary to insert the spacer 19 at the bottom of 10.

Furthermore, a transport vehicle 18 is placed in the space below the truck frame 14.
The front jack 7.7 and the outrigger jack 10.10 are retracted and mounted on the carrier 18H of the transport vehicle 18, and the front jack 7.7 and the outrigger jack 10 are
．． 10 is stored within the width of the vehicle body, and the large pile driver 1 is transported by a transport vehicle 18.

Further, the removed crawlers 15, 15, etc. are loaded onto another transport vehicle 20 and transported, as shown in FIG.

As described above, the disassembly and transportation method of the present invention has features in the attachment of the front jack 7.7 and outrigger jack 10.10, and the front jack 7.7 and outrigger jack 10.10 are Since it is not necessary to disassemble the crawler 15.15 and mount the blade on the transport vehicle 18, and also to disassemble the outrigger jack 10.10, the efficiency of the disassembly and transportation work of the large pile driver 1 is improved. and safety can be improved.

〔Effect of the invention〕

As described above, the method for disassembling and transporting a large pile driver according to the present invention is to provide an arm equipped with a front jack so that it can be opened and closed, an arm equipped with an outrigger jack that can be folded toward the rear of the vehicle body, and a truck frame on both sides of the truck frame. A large pile driver that can be expanded and contracted in the width direction of the car body with a crawler expansion/contraction cylinder, the front jack and the outrigger jack are each extended to ground the crawler, and the crawler expansion/contraction cylinder is extended. After removing the crawler from the truck frame, contract each jack to ground the bottom surface of the truck frame, expand the arms of the front jacks beyond the width of the transport vehicle, and extend the front jacks and outrigger jacks. Raise the bottom of the truck frame to a level above the vehicle height, turn the truck frame 90 degrees,
The transport vehicle is pulled into the space under the truck frame, each jack is deflated and mounted on the transport vehicle's loading platform, and the front jack and outrigger jack are stored within the width of the vehicle body.
The blade can be mounted on a transport vehicle using the provided front jack and outrigger jack, and there is no need to disassemble the outrigger jack, improving efficiency and safety when disassembling and transporting large pile drivers. can do.
