たつてクローラを巻回したクローラ走行装置に関
する。[Detailed Description of the Invention] The present invention provides a track frame with a plurality of guide wheels that act on the inner circumferential surface of the ground-contacting side portion of the crawler, and a drive wheel, a tension wheel, and a crawler across the guide wheels. This invention relates to a crawler traveling device that is wound with.

ものが知られている。 Conventionally, this type of crawler traveling device
For example, as disclosed in Japanese Utility Model Application Publication No. 57-159583, a crawler detachment prevention member fixed to the track frame is located on the lateral side of the core protrusion of the crawler and extends between the wheels. What has been established is known.

た場合に、クローラがガイド輪から離れて垂れた
状態となつて、前記外れ防止部材を芯金突起から
離れ、その状態でクローラに横方向の力がかかる
と、クローラがガイド輪から外れるとともに緊張
輪及び駆動輪から外れてしまう問題があつた。 However, in the crawler traveling device, even though the crawler is provided with a member to prevent the crawler from coming off, when the crawler goes over a ridge or rides on a relatively high raised object, the crawler separates from the guide wheel and becomes sagging. When the detachment prevention member is separated from the core protrusion and a lateral force is applied to the crawler in this state, there is a problem in that the crawler comes off the guide wheel and also comes off the tension wheel and the drive wheel.

進行に伴い、その大きく持ち上がつた機体が畦等
の頂部を支点として回転して下降接地するため、
その接地の際の衝撃が大で安全性に欠ける等の欠
点を有していた。 In addition, in the crawler traveling device described above, since the crawler detachment prevention member is in a fixed state and the spacing between adjacent guide wheels is almost constant, the crawler's contact surface is This prevents the top of the ridge, etc. from getting into the area, so after the front of the aircraft lifts up significantly, as the aircraft advances, the aircraft rotates around the top of the ridge, etc. as a fulcrum and descends to the ground. In order to
It has drawbacks such as a large impact when it touches the ground and a lack of safety.
そこで、従来は、例えば、実開昭52−14646号

するように構成していた。 Therefore, conventionally, for example, as disclosed in Japanese Utility Model Application Publication No. 52-14646, guide rings are individually positioned between the core protrusions, corresponding to each guide ring.
Alternatively, disengagement prevention members for the crawler are provided on both sides of the core protrusion, and each disengagement prevention member is provided with a biasing mechanism such as a compression spring.
The detachment prevention member was configured to be biased toward the side of contact with the inner peripheral surface of the crawler.
ところが、前記クローラ走行装置においては、

品点数が多く、高価になると共に取付に手間を要
する欠点があつた。 However, in the crawler traveling device,
Since each guide ring is provided with a detachment prevention member, the number of parts is large, the cost is high, and installation is time-consuming.
本考案は、前記実状を鑑みて為されたものであ
つて、部品点数を少なくして製造コスの低減化
や、生産性の向上を図り、かつ、畦越え等におい

するクローラ走行装置の提供を目的とする。 The present invention has been developed in view of the above-mentioned circumstances, and aims to reduce manufacturing costs and improve productivity by reducing the number of parts, and to prevent the aircraft from lifting up or descending when going over ridges, etc. The purpose of the present invention is to provide a crawler traveling device that reduces the impact of time.

とを特徴構成とする。 In order to achieve the above-mentioned object, the crawler traveling device according to the present invention has a structure in which two adjacent guide wheels are arranged near the center of the ground-contacting side portion of the crawler in the longitudinal direction. Set the distance to be larger than the distance between other adjacent guide wheels at a position different from this guide wheel, and
The crawler detachment prevention member is provided in a state that spans between two adjacent guide wheels disposed near the center and is located laterally of the core protrusion of the crawler, and further, A biasing mechanism is provided for urging the detachment prevention member to be displaced toward the contact side with the crawler, and the downward surface of the detachment prevention member is positioned near the center of the ground-contacting side portion of the crawler in the front-rear direction. The guide wheels are characterized in that they are curved upward in the middle between the adjacent guide wheels.

ともに取付時間が少なくなつて、生産性の向上が
図れた。 That is, since the crawler detachment prevention member is provided so as to span two guide wheels arranged near the center of the ground-contacting side portion of the crawler, the conventional structure in which a detachment prevention member is provided on each guide wheel is provided. Compared to the previous model, the number of parts is smaller, the structure can be made at a lower cost, and the installation time is reduced, which improves productivity.

ようにして、クローラがガイド輪から外れるのを
防げる等の効果を奏するに至つた。 Moreover, the distance between the two adjacent guide wheels arranged near the center is made larger than the distance between the other two guide wheels arranged near the ends, and the distance between the two adjacent guide wheels arranged near the center is made larger, and the distance between the two guide wheels arranged near the center is made larger, and the distance between the two guide wheels arranged near the center is made larger than the distance between the two guide wheels arranged near the center, and the distance between the two guide wheels arranged near the center is made larger than the distance between the two guide wheels arranged near the center. A biasing mechanism is provided that biases the member to be displaced to the side of contact with the crawler, and further,
The downward facing surface of the detachment prevention member is curved upward in the middle between the two adjacent guide wheels disposed near the center, so when going over a ridge etc. When the crawler is installed and rides on the top of a ridge, etc. between two guide wheels, the crawler is curved so as to come into pressure contact with the protruding curved surface of the detachment prevention member, and furthermore, while riding on the top of the ridge, etc., the crawler is biased. Since the detachment prevention member is pushed up over a large range in the longitudinal direction at the center of the crawler against the biasing force of the member, the support position of the aircraft by ridges etc. is lowered, and it is possible to suppress large lifting of the front of the aircraft and also prevent the lifting. The impact caused by the crawler's downward contact with the ground when it crosses over a ridge can be reduced, making it possible to smoothly and safely go over a ridge or over a relatively large bulge.Furthermore, the biasing member allows the detachment prevention member to come into contact with the crawler. As a result, the crawler is prevented from sagging and the crawler is prevented from coming off the guide wheel.
