Abstract

(57) [Abstract] [Purpose] By constructing the crawler belt pad 2 with the two pad members 2a and 2b, even if one pad member is damaged, the other pad member can continue to be used. If so, it is an object to provide a track pad that can be economically used by replacing only the damaged pad member. [Structure] A hook portion 4a that engages with an end of the shoe plate 1 is formed at one end in an elastic member that is shorter than half the length of the shoe plate 1 and has a substantially rectangular cross section. Two pad members 2a, 2b each having a cored bar 4 having a connecting portion formed at the other end therein.
The connecting portions 4b and 4b are bolted to each other.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a track pad that is attached to each track plate that constitutes a track used in a tracked vehicle for road surface protection.

[0002]

[Prior Art]

 In order to protect the road surface from the crawler track, pads have been attached to the tread side of each track plate that constitutes the crawler track. As a conventional track pad of this type, for example, the one disclosed in Japanese Utility Model Publication No. 62-32138 is known. In this conventional one, the crawler belt pad for one crawler plate is a single one.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional crawler belt pads, one crawler track pad is integrally formed for each crawler plate. Therefore, even if it is partially damaged due to uneven wear or the like, one whole crawler track pad must be replaced. It was uneconomical.

The present invention has been conceived in view of the above, and by constructing a crawler pad with two pad members, even if one pad member is damaged, the other pad member continues. The object of the present invention is to provide a track pad that can be economically used by replacing only the damaged pad member if it can be used.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the crawler belt pad according to the present invention has a crawler plate 1 at one end in an elastic member which is shorter than 1/2 of the length of the crawler plate 1 and has a substantially rectangular cross section. Two pad members 2a, 2b each having a hook 4a engaged with one end thereof and having a connecting portion 4b formed at the other end are internally attached to each of the connecting portions 4b, 4b by bolts. It is configured to be united.

[0006]

[Work]

 The two pad members 2a and 2b are mounted by engaging the hook portions 4a and 4b with the ends of the shoe plate 1 and connecting the opposing connecting portions 4b and 4b with bolts 8.

[0007]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes a crawler plate, and the crawler plate 1 is endlessly connected by a track link (not shown) to form a crawler belt. Reference numeral 2 denotes a crawler belt pad according to the present invention which is easily attached to the tread side of the crawler plate 1 according to the present invention. The crawler belt pad 2 is composed of two pad members 2a and 2b which are separated in the longitudinal direction of the crawler plate 1. It consists of Since both pad members 2a and 2b have the same structure, one of them will be described below. Reference numeral 3 denotes an elastic member. The elastic member 3 has a width narrower than the width of the track plate 1, a length shorter than 1/2 of the length of the track plate 1 and a substantially rectangular cross section. In this elastic member 3, a plate-shaped cored bar 4 is horizontally arranged and installed in the longitudinal direction. The cored bar 4 projects in both lengthwise directions of the elastic member 3, and one end of the cored bar 4 serves as a hook 4a bent into a shape that engages with the end of the shoe plate 1 in a detachable manner. In addition, the other side end portion is twisted vertically and serves as a connecting portion 4b having a bolt hole.

The elastic member 3 is made of a hard elastic rubber material such as natural rubber, synthetic rubber, or plastic, and the core material 4 is inserted when the elastic member 3 is formed.

An anti-slip groove 5 is provided on the upper surface of the elastic member 3 in a mountain shape in the longitudinal direction. A groove 6 that engages with a lug on the tread surface of the shoe plate 1 is provided on the lower surface of the elastic member 3 over the entire length thereof, and a plurality of recesses 7 are provided at the portion of the lower surface that abuts the shoe plate 1. Has been.

In the above structure, in order to attach the crawler belt pad 2 to the crawler plate 1, the two pad members 2a and 2b are engaged with the hooks 4a of the respective cored bars 4 to the end portions of the crawler plate 1. And the lower surface of each of them is brought into contact with the tread surface of the track plate 1. As a result, the pad members 2a, 2b are brought into a state in which the respective connecting portions 4b, 4b face each other. Therefore, the bolt 8 is inserted into the bolt holes of the both connecting portions 4b, 4b and tightened with the nut 9. To wear. By doing so, both pad members 2a and 2b become the crawler belt pad 2 and are attached to each crawler plate 1 as the crawler belt pad. Then, the crawler belt pad 2 is run with the pad 2 attached, but if one pad member is damaged due to this running or the like, only the damaged pad member is removed and replaced. At this time, since the two pad members 2a and 2b constituting the crawler belt pad 2 are the same part, the parts can be easily handled when they are replaced. In the above embodiment, the connecting portions 4b, 4b of the cored bar 4 are formed by vertically twisting the cored bar 4, but this may be left horizontal.

[0011]

[Effect of the device]

 According to the present invention, since the crawler belt pad is composed of the two pad members 2a and 2b, if one pad member is damaged, the other pad member can be used continuously. Only the damaged pad member can be replaced and can be economically used. Further, since the pad members 2a and 2b have the same structure, even if there are two members (pad members) constituting the crawler belt pad, one pad member can be manufactured. Therefore, the cost does not increase.
