Description

【0001】
【発明の属する技術分野】
本発明は、クレーンを旋回自在に取付けた車両の前方部および後端部に、車両の左右に張出して設置されるアウトリガ装置をそれぞれ取付けると共に、車両の後端部にレッキングアーム取付け装置を備えてなるレッカー車に関するものである。
【0002】
【従来の技術】
従来のレッカー車として図3および図4に示されたものが知られている(例えば、特許文献1参照。)。
【0003】
図3および図4に示す如く、レッカー車は、クレーン1を旋回自在に取付けた車両2の前方部および後端部に、車輌の左右に張出して接地されるアウトリガ装置3、4をそれぞれ取付けると共に、車両2の後端部にレッキングアーム取付け装置5を備えており、レッキング時には、前記レッキングアーム取付け装置5にレッキングアーム6を取付け、このレッキングアーム6の先端部に牽引すべき車両の前部あるいは後部を載置するものである。また、クレーン作業する時には、前記各アウトリガ装置3、4を接地させ、クレーン1を使用するものである。
【0004】
ところでこの種のレッカー車は、レッキング時に生じる車両2前輪2aの負荷減少を可及的に小さく押さえるため、所定の長さを有するレッキングアーム6先端部の被牽引車の支持力点が車両2の後車輪2bに出来るだけ近づくよう、車両2の後端部のレッキングアーム取付け装置5を、車両2の後輪2bに出来るだけ近づけて配置する必要がある。
【0005】
そのため、図4に示すように車両2の後端部のアウトリガ装置4の外箱4a、4aを、車両2の後端部に上下併設状態で横設した上下一対に構成し、互いに車両2の反対側の側方に伸縮可能なよう内箱4c、4cを伸縮可能なよう前記一対の外箱4a、4aに嵌挿し、その外箱4a、4aの後側にレッキングアーム取付け装置5を配置したものが知られていた。
【0006】
あるいは、図示しないが車両2の後端部のアウトリガ装置4の外箱を1個の箱とし、その左右の端部から左右一対の内箱4c、4cをそれぞれ嵌挿するようにしたものも知られている。
【0007】
このように、車両2の後端部に前後に併設状態で一対の外箱を横設したものに比べ、レッキングアーム取付け装置5を車両2の後車輪2bに近づけて配置することによりレッキング能力を増大するようにしていた。

【発明が解決しようとする課題】
ところが、近年、より大型の車両を牽引できるようにしたい、あるいはレッカー車の車両を小型化しても同等のレッキング能力を確保したい等の理由からさらなるレッキング能力の向上が望まれている。
【0010】
そこで、本発明は、上述した従来のレッカー車に比べさらにレッキング能力を向上することができるレッカー車を提供しようとするものである。
【0011】
【課題を解決するための手段】
本願の請求項1に記載されたレッカー車は、クレーンを旋回自在に取付けた車両の前方部および後端部に、車両の左右に張出して設置されるアウトリガ装置をそれぞれ取付けるとともに、車両の後端部にレッキングアーム取付け装置を備えてなるレッカー車において、車両の後端部のアウトリガ装置の外筒をその中央部が車両前方に向かって屈曲した平面視くの字状に構成し、その先端部にジャッキを備えた左右一対の内筒を互いに車両の反対側の側方に伸縮可能なよう前記外筒の両端からそれぞれ嵌挿すると共に、後端部のアウトリガ装置の前記外筒の中央部後側に前記レッキングアーム取付け装置を配置したことを特徴とする。
【0012】
この構成により従来のレッカー車に比べ、さらにレッキングアーム取付け装置を車両の後車輪に近づけて配置できるので、レッキング能力を増大することができるのである。
【0013】
【発明の実施の形態】
図1に、本願発明の実施の形態に係るレッカー車の側面図を示す。レッカー車は、クレーン11を旋回自在に取付けた車両12の前方部および後端部に、車両の左右に張出して接地されるアウトリガ装置13、14をそれぞれ取付けている。車両12の後端部にレッキングアーム取付け装置15を備えており、レッキング時には、レッキングアーム取付け装置15にレッキングアーム16を取付け、このレッキングアーム16の先端部に牽引すべき車両17の前部あるいは後部を載置するようになっている。また、クレーン作業をする時には、前記各アウトリガ装置13、14を接地させ、クレーン11を使用するようになっている。
【0014】
図2は図1のA矢視図であって、レッカー車の後端部を上方から見た図である。車両12の後端部のアウトリガ装置14の外筒18をその中央部14aが車両前方に向かって屈曲した平面視くの字状に構成している。本実施の形態では、前記外筒18の左側外筒18aと右側外筒18bとを同一の高さに構成し、左右の外筒端面同士を車両中央部でつなぎ合わせる構造を採用している。
【0015】
なお、後端部アウトリガ14の外筒の構成としては、右側外筒18aと左側外筒18bを高さ違いにして、上下に併設するようにしてもよいことは勿論である。この場合は、右側外筒18aと左側外筒18bの長さをより長く構成できるため、それに内挿する内筒の長さもより長いものとでき、その結果後端部アウトリガ14の張出幅をより大きなものとできるという利点を有する。
【0016】
前記外筒18の先端部にはジャッキ19、19を備えた左右一対の内筒20、20を互いに車両12の反対側の側方に伸縮可能なよう前記外筒18の両端からそれぞれ嵌挿している。
【0017】
レッキングアーム取付け装置15は、後端部アウトリガ装置14の前記外筒18が車両前方に向かって屈曲した平面視くの字状に構成した中央部後側に配置している。16は、レッキングアーム取付け装置15に取付けたレッキングアームである。
【0018】
図2に示したL1は車両12の後車輪12bから前記レッキングアーム取付け装置15までの距離である。本願発明の上述した構成により、内筒20を外筒18に格納した時のジャッキ19の後車輪12bに対する前後位置を従来と同じとしても、前記距離L1を従来のレッカー車よりも短くすることができる。したがって、レッキングアーム16の長さL2は従来と同じでありながらも、後車輪12bからレッキングアーム16の支持力点21までの距離Lを従来のレッカー車よりも短くすることができる。
【0019】
すなわち、レッキング時に生ずる車両12の前車輪12aの負荷減少を可及的に小さく押さえることができるので、前記支持力点21に負荷できる許容荷重であるレッキング能力を高めることができる。
【0020】
【発明の効果】
本願発明のレッカー車は、車両の後端部のアウトリガ装置の外筒をその中央部が車両前方に向かって屈曲した平面視くの字状に構成し、前記外筒の中央部後側に前記レッキングアーム取付け装置を配置したので、従来のレッカー車に比べ、レッキングアーム取付け装置を車両の後車輪に近づけて配置できることとなり、レッキングアーム支持力点におけるレッキング能力を増大することができる。

Utility Model Registration No. 2581210 (Page 2, FIG. 1-2)
[0009]
[Problems to be solved by the invention]
However, in recent years, further improvement in the wrecking capacity has been desired for reasons such as the ability to tow a larger vehicle or to secure the same wrecking capacity even when the size of the wrecker vehicle is reduced.
[0010]
Therefore, an object of the present invention is to provide a tow truck capable of further improving the wrecking ability as compared with the conventional tow truck described above.
[0011]
[Means for Solving the Problems]
The tow truck according to claim 1 of the present application has an outrigger device that is installed to extend to the left and right of the vehicle at a front portion and a rear end portion of a vehicle on which a crane is pivotably mounted, and a rear end portion of the vehicle. In a tow truck equipped with a wrecking arm mounting device, the outer cylinder of the outrigger device at the rear end of the vehicle is formed in a U-shape in a plan view in which the center portion is bent toward the front of the vehicle, and a jack is provided at the front end thereof. A pair of left and right inner cylinders each having a pair are inserted from both ends of the outer cylinder so as to be expandable and contractible to the opposite side of the vehicle, and the rear end portion of the outer cylinder is located at the center rear side of the outer cylinder. The wrecking arm mounting device is disposed.
[0012]
With this configuration, the wrecking arm mounting device can be arranged closer to the rear wheel of the vehicle than in a conventional tow truck, so that the wrecking ability can be increased.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows a side view of a tow truck according to an embodiment of the present invention. In the tow truck, outrigger devices 13 and 14 are attached to the front and rear ends of a vehicle 12 on which a crane 11 is pivotably mounted, and are extended to the left and right of the vehicle and grounded. At the rear end of the vehicle 12, a wrecking arm mounting device 15 is provided. At the time of wrecking, a wrecking arm 16 is mounted on the wrecking arm mounting device 15, and a front or rear portion of a vehicle 17 to be towed to the tip of the wrecking arm 16. Is to be placed. When performing a crane operation, the outrigger devices 13 and 14 are grounded, and the crane 11 is used.
[0014]
FIG. 2 is a view taken in the direction of the arrow A in FIG. 1 and is a view in which a rear end of the tow truck is viewed from above. The outer cylinder 18 of the outrigger device 14 at the rear end of the vehicle 12 has a central portion 14a that is bent toward the front of the vehicle and has a U-shape in plan view. In the present embodiment, the left outer cylinder 18a and the right outer cylinder 18b of the outer cylinder 18 are configured to have the same height, and a structure is employed in which the left and right outer cylinder end faces are joined at the center of the vehicle.
[0015]
It should be noted that the outer cylinder of the rear end outrigger 14 may of course be configured such that the right outer cylinder 18a and the left outer cylinder 18b have different heights and are arranged vertically. In this case, since the length of the right outer cylinder 18a and the left outer cylinder 18b can be made longer, the length of the inner cylinder inserted therein can be made longer, and as a result, the overhang width of the rear end outrigger 14 can be reduced. This has the advantage that it can be made larger.
[0016]
A pair of left and right inner cylinders 20, 20 having jacks 19, 19 are fitted into the distal end of the outer cylinder 18 from both ends of the outer cylinder 18, respectively, so that the inner cylinders 20, 20 can expand and contract toward the opposite side of the vehicle 12. I have.
[0017]
The wrecking arm mounting device 15 is disposed at the center rear side of the rear end outrigger device 14 which is formed in a U-shape in a plan view in which the outer cylinder 18 is bent toward the front of the vehicle. Reference numeral 16 denotes a wrecking arm attached to the wrecking arm attachment device 15.
[0018]
L1 shown in FIG. 2 is a distance from the rear wheel 12b of the vehicle 12 to the wrecking arm mounting device 15. According to the above-described configuration of the present invention, the distance L1 can be shorter than that of a conventional tow truck even when the front and rear positions of the jack 19 with respect to the rear wheel 12b when the inner cylinder 20 is stored in the outer cylinder 18 are the same as those of the conventional tow truck. . Therefore, while the length L2 of the wrecking arm 16 is the same as that of the conventional wrecker, the distance L from the rear wheel 12b to the supporting force point 21 of the wrecking arm 16 can be shorter than that of the conventional wrecker.
[0019]
That is, the decrease in the load on the front wheels 12a of the vehicle 12 that occurs during wrecking can be suppressed as small as possible, so that the wrecking ability, which is the allowable load that can be applied to the supporting force point 21, can be increased.
[0020]
【The invention's effect】
The tow truck according to the present invention is characterized in that the outer cylinder of the outrigger device at the rear end of the vehicle is formed in a V-shape in a plan view in which the center is bent toward the front of the vehicle, and the wrecking is performed on the rear side of the center of the outer cylinder. Since the arm mounting device is disposed, the wrecking arm mounting device can be disposed closer to the rear wheel of the vehicle as compared with a conventional tow truck, and the wrecking ability at the wrecking arm supporting force can be increased.
