Description

この発明は建設機械の警報装置の技術分野に属する。更に詳細には、建設機械の警報装置の警報音発生器の構造に関する。 The present invention belongs to the technical field of construction machine alarm devices. More particularly, the present invention relates to a structure of an alarm sound generator of an alarm device for construction machinery.

従来から、油圧ショベル等は下部走行体とその上に旋回可能に載置された旋回体を有する建設機械では、走行したり、旋回したり、或いは作業装置を仰伏動させる作業時には、周囲の作業者に注意を与えるために、これらの作業者に対し警報装置を備えたものがある。建設機械の警報装置は警報音が周囲の作業者によく聞こえるようにし、かつオペレータが警報音を耳障りと感じないようにして安全性と作業性を向上させるために警報音発生器の取付け場所や構成などに関して種々の工夫がなされてきた。 Conventionally, in a construction machine having a lower traveling body and a swivel mounted so as to be able to swivel thereon, a hydraulic excavator or the like is used when traveling, swiveling, or working for raising and lowering a working device. Some of these workers are equipped with alarm devices to give attention to the workers. The warning device of construction machinery is designed to make the alarm sound well audible to surrounding workers and to prevent the operator from feeling the alarm sound harsh and improve the safety and workability. Various contrivances have been made regarding the configuration and the like.

例えば、取付け場所としては、特許文献１、特許文献２に開示されているように、カウンタウエイトの外面とか、運転席の後方の近くにある支柱に設けられている。又、警報音発生器としてはブザーや、１個のホーンを利用した構成が採用されている。
公開特許公報、特開平５−９７３９４号 公開特許公報、特開２００１−１２０４０７号 For example, as disclosed in Patent Document 1 and Patent Document 2, the mounting location is provided on the outer surface of the counterweight or on a support column near the rear of the driver's seat. Further, a configuration using a buzzer or one horn is employed as the alarm sound generator.

ブザー音は機械的な音がして周囲の作業者に危険を報せるという課題があり、警報音としてはあまり芳しくない。また、ホーンを１個だけ設けた場合は、音量の調節が複雑であるだけでなく、ホーンが故障した場合にホーンの交換作業、或いは修理作業が複雑で、建設作業の中断が余儀なくされるという課題が生じる。
本発明は、上記問題を解決するためになされたものであり、以下のような解決手段を採用している。 There is a problem that the buzzer sounds mechanically and can report the danger to surrounding workers. In addition, when only one horn is provided, not only is the volume adjustment complicated, but if the horn breaks down, the replacement or repair of the horn is complicated, and construction work must be interrupted. Challenges arise.
The present invention has been made to solve the above-described problems, and employs the following solutions.

請求項１に記載の発明は、下部走行体と該下部走行体の上側に載置されて旋回可能な旋回体を有する建設機械の警報装置において、前記警報装置は警報音を発生する複数個のホーンを具備し、該複数個のホーンを相互に前後方向に偏位させて配置すると共に、上下方向にも相互に偏位させてホーンの縁部が重なるか、或いは、近接した位置に在るように配置してキャブの床下のフレーム本体に固定したことを特徴としている。 The invention according to claim 1 is an alarm device for a construction machine having a lower traveling body and a revolving body mounted on the upper side of the lower traveling body and capable of turning, wherein the alarm device includes a plurality of alarm sounds. A horn is provided, and the plurality of horns are displaced from each other in the front-rear direction, and are also displaced from each other in the vertical direction so that the edges of the horns overlap or are close to each other. It is characterized by being arranged and fixed to the frame body under the floor of the cab.

請求項２に記載の発明は、前記複数個のホーンは２個のホーンとしたことを特徴としている。 The invention described in claim 2 is characterized in that the plurality of horns are two horns.

また、請求項３に記載の発明は、請求項１又は請求項２の何れか１に記載の発明において、前記旋回体のフロントカバーに、前記ホーンの略正面位置に音抜け用の開口を設けたことを特徴としている。 According to a third aspect of the present invention, in the first or second aspect of the present invention, the front cover of the revolving structure is provided with an opening for sound removal at a substantially front position of the horn. It is characterized by that.

複数個のホーンを設けたことにより、大きな音量の出力が容易となり、更に個別にオン・オフすることにより音量の調節が容易となる。更に、ホーンの一部が故障した場合でも建設作業を続行できるという効果が得られる。また、ホーンの配置を相互に前後方向及び上下方向に偏位させたことにより設置スペースを小さくでき、組立が容易になるという効果が得られた。また、音の出る開口を小さくでき、意匠的な工夫が容易になるという効果が得られる。 By providing a plurality of horns, it is easy to output a large volume, and furthermore, the volume can be easily adjusted by turning on / off individually. Furthermore, the construction work can be continued even when a part of the horn breaks down. Moreover, the installation space can be reduced by shifting the arrangement of the horns in the front-rear direction and the up-down direction. In addition, it is possible to reduce the opening from which sound is produced, and the effect that the design device is facilitated can be obtained.
