Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elastic track plate attached to each iron track plate constituting a track of a tracked vehicle such as a bulldozer, a power shovel, and the like. , The purpose is to improve work efficiency.

[0002]

2. Description of the Related Art Iron crawler belts mounted on endless track vehicles have recently been made of urethane or rubber elastic material on each track constituting the crawler belts to damage the road surface when traveling on a normal paved road surface. When the body is attached, the crawler belt is constructed by removing the crawler belt from the endless track vehicle or attaching the body part to the endless track vehicle as shown in FIG. of,
The metal plate 11 is integrally formed on the rear surface of each metal shoe plate 14 having the raised portion 15 formed on one side,
The metal plate 14 has mounting bolts 12 projecting to the back side at the four corners of the metal plate 11, and one elastic shoe plate integrally attached with an elastic body 13 such as urethane on the surface side thereof. The bolt 16 is inserted into the bolt hole 17 of the groove portion 16 formed between the respective projections 15, and is integrally tightened and fixed by a tightening nut (not shown) through a spring washer from the opposite side.

[0003]

However, in the above-mentioned conventional elastic crawler plate, each of the metallic crawler plates 1 is used.
In the case of attaching to No. 4, since it is tightened and fixed to the metal plate 14 by the bolts 12 provided at the four corners of each elastic shoe plate, the workability is remarkably poor.
In particular, one of the four mounting bolts 12 at the four corners is located inside the crawler belt in the crawler vehicle, which makes mounting work extremely difficult. By the way, the time required to attach the elastic crawler plate to the crawler belt for one standard power shovel (average 84) is about 4 hours.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems in the prior art and improves the workability of attaching the elastic track plate to each track plate of the endless track zone.
Specifically, it is an elastic crawler plate attached to each iron crawler plate constituting a crawler track of a tracked vehicle, the elastic crawler plate has a metal plate integrally on its back surface, and the metal plate has Elasticity for a crawler belt characterized in that a mounting bolt is projectingly provided at one end in its length direction, and a bending hook capable of engaging with the end of the iron track plate is provided at the other end. Regarding footwear.

[0005]

[Function] The metal plate on the rear side is set so that the side where the folding hook is provided is the back (head), and from the side of the crawler track to the iron crawler plate to which the crawler is to be attached (the crawler on the vehicle side First, the folding hook is attached to the inner end of the track plate located on the inner side of the track) by utilizing the groove portion of the track plate, and further on the opposite side of the metal plate (outer side of the crawler track on the side surface of the endless track vehicle). The mounting bolt is inserted into the bolt hole formed in the outer end portion of the iron-made shoe plate, and tightened and fixed by the nut from the opposite surface side.

[0006]

The concrete contents of the present invention will be described below with reference to FIG.
And based on the embodiment shown in FIG. 2,
Reference numeral 1 denotes a metal plate, and 4 denotes an elastic body such as urethane or rubber, which is integrally attached to the surface side of the metal plate 1. The metal plate 1 is formed in a corrugated shape in the width direction thereof so as to correspond to the projections and depressions 6 of the iron shoe plate 5 to be attached and the grooves 7 and 7 formed between the projections 6 and 6. At the same time, the mounting bolts 2, 2 are provided at one end in the lengthwise direction of the portion of the iron-made track plate 5 that is made to project in correspondence with the groove portions 7, 7, and further at the other end, Bending hooks 3, 3 that can be engaged with the groove portions 7, 7 at the ends of the iron shoe plate 5 are formed.

In this case, the distance between the tips of the folding hooks 3 and 3 and the metal plate 1 is ideally set to be approximately equal to the thickness of the groove portion 7 of the iron shoe plate 5. Therefore, the elastic shoe plate of the present application integrally has the metal plate 1 on the back surface of the elastic body 4 as described above, and the metal plate 1 has the mounting bolts 2 on the one end side in the length direction as in the conventional case. , 2,
Moreover, since the other end is provided with the folding hooks 3, 3 which can be engaged with the end of the iron-made shoe plate 5, the mounting is performed as follows.

That is, the metal plate 1 provided on the back side of the elastic crawler plate is positioned from the side surface of the crawler vehicle to the rear side of the crawler track, with the side provided with the bending hooks 3 being the head. With respect to the iron-made track plate 5 to which the crawler belt is to be attached, first, the folding hooks 3, 3 are engaged with the groove portions 7, 7 at the ends of the iron-made track plate 5 located at the back (inside of the vehicle), and further the metal plate. Insert the mounting bolts 2 and 2 on the opposite side of 1 (positioned outside the endless track vehicle) through the bolt holes 8 and 8 formed at the outer end (seen from the vehicle) of the iron track 5 described above. From the opposite surface side, the spring washer 9 is interposed and the nut 10 is tightened and fixed.

[0009]

As described above, the present invention is an elastic crawler plate attached to each iron crawler plate constituting a crawler belt of a crawler vehicle, and the elastic crawler plate integrally has a metal plate on its back surface. At the same time, the metal plate is provided with a mounting bolt projecting from one end in the lengthwise direction, and the other end is provided with a bending hook capable of engaging with the end of the iron track plate. Therefore, when the elastic track plate is attached to the iron track plate, it is positioned inside the tracked vehicle as compared to the conventional one in which the mounting bolts protruding at the four corners are used to tighten and fix each one. With a folding hook for the narrow part of the vehicle, you can extend your hand from the outside of the vehicle toward the inside and simply hook it, and there is no need for the operator to enter the narrow inside of the track in the vehicle. Time is at least half, thereby improving greatly the workability, it is possible to reduce cost.
