Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crawler supporting structure for a crawler type traveling body to which a crawler can be attached and detached. 2. Description of the Related Art Some crawler-type traveling bodies such as self-propelled cranes extend the width of the right and left crawlers during operation and reduce the width of the right and left crawlers during transportation. In some cases, the crawler is removed due to weight restrictions and the vehicle and the crawler are transported separately. The crawler support structure of this type of crawler type traveling body includes, for example, as shown in FIGS. 4 and 5, a pair of axle beams 2 extending from the front and rear portions of a track frame 1 to the left and right of the vehicle body. A pair of sub-axles 3 are provided so as to be rotatable in the horizontal direction, and when the width of the right and left crawlers is expanded, the sub-axles 3 are inserted into the through holes 5 of the crawler frame 4 and bolted to the tip of the sub-axle 3. connecting the 6 and the bracket 7 of the crawler frame 4, at the time of reduction of the left and right crawler width, crawler 8 fold the sub axle 3 to the outside of the crawler frame 4 by inserting the a Kusurubimu 2 into the through-hole 5 of the crawler frame 4 I support. [0004] However, in the above-described structure, the width of the stopper bolted to the tip of the sub-axle is larger than the through hole of the crawler frame. It was necessary to remove the axle from the tip, and the removal and installation of the stopper was troublesome, which could cause problems such as forgetting to tighten the bolts, and the removal and installation of the crawler required time and effort. SUMMARY OF THE INVENTION It is an object of the present invention to provide a crawler supporting structure for a crawler type traveling body in which a crawler can be easily removed and attached. In order to achieve the above-mentioned object, the present invention provides a pair of sub-apertures at the tip of an axle beam.
The provided rotatably in a horizontal direction Kusuru, in the crawler support structure for crawler type traveling body for supporting the crawler by inserting the sub-axle in the through hole of the crawler frame, to the tip of each sub <br/> Buakusuru, sub Approximately the same width or width as the axle
Narrowly formed brackets are provided, and a link is pivotally supported at the tip of each bracket by a support pin so as to be rotatable in the horizontal direction, and the tip of the link and the bracket of the crawler frame are connected to each other. A locking pin detachably connected to the link pin;
The tip of the claw and the bracket of the crawler frame are locked
When the link and the sub-actuator are
With a rotation restriction pin inserted into the bracket at the end of the through,
With the locking pin and the rotation restricting pin removed,
The axle beam, sub-axle and link are straight
It is characterized in that that. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on an embodiment shown in FIGS. The crawler-type traveling body 10 includes a pair of sub-axles 1 rotatable in the horizontal direction at the ends of a pair of axle beams 12 extending from the front portion and the rear portion of the track frame 11 to the left and right of the vehicle.
3 and a bracket 14 is provided at the tip of each sub axle 13.
Are mounted, and a link 15 is pivotally supported at the tip of each bracket 14 by a support pin 16 so as to be rotatable in the horizontal direction. [0008] The bracket 14 is abbreviated to the sub-axle 13.
If it is formed to have the same width or narrow width and is bolted to the tip of the sub-axle 13, compatibility and commonality with the conventional sub-axle can be achieved.
And an integral structure. When the width of the left and right crawlers 17 is extended to support the crawlers 17, the sub axles 13, 13 are connected to the through holes 1 of the crawler frame 18 as shown in FIG.
9, each bracket 14 is projected from the through hole 19 to the outside of the crawler frame 18, and the tip of the link 15 is fixed to the bracket 20 of the crawler frame 18 by the locking pin 2.
Connect at 1. At this time, a rotation restricting pin 22 is inserted into the link 15 and the bracket 14 to restrict the rotation of the link 15. When the width of the left and right crawlers 17 is reduced to support the crawlers 17, the locking pin 21 is pulled out to release the connection between the link 15 and the bracket 20, and the cylinder 23 provided on the track frame 11 is reduced. And crawler 17
2, the axle beam 12 inside the sub axle 13 is inserted into the through hole 19 of the crawler frame 18 as shown in FIG. 2, and each sub axle 13 protruding from the through hole 19 is rotated. Along the outside of the crawler frame 18, attach the tip of the link 15 to the crawler frame 1.
8 with a locking pin 21. When the crawler 17 is to be removed, as shown in FIG.
The sub axle 13 and the link 15 are respectively rotated to be linear with the axle beam 12, and the cylinder 23 is reconnected to the bracket 24 inside the crawler frame 18,
The cylinder 23 is extended and the crawler 17 is removed. Also,
When reassembling the crawler 17, the order is reversed. As described above, when removing and attaching the crawler 17, the link 15 can be removed without removing the link from the sub-axle 13, so that the crawler 17 can be easily removed and attached, and problems such as forgetting to tighten the bolts can be achieved. Also does not occur. As described above, the crawler supporting structure for a crawler-type traveling body according to the present invention has a sub axle at the tip of an axle beam inserted into a through hole of a crawler frame in order to support the crawler. Provide a bracket at the tip,
A link is pivotally supported on the bracket so as to be rotatable in a horizontal direction,
Since the tip of the link was detachably connected to the bracket of the crawler frame by a pin, when removing the crawler, the connection pin between the link and the bracket of the crawler frame was removed, and the link was rotated to make the crawler straight with the axle beam. Remove. In addition, when the crawlers are re-assembled, the crawlers are re-assembled in the reverse order, so that the crawlers can be easily removed and attached without removing the link from the sub-axle, and problems such as forgetting to tighten bolts do not occur.
