Description

本発明は振動リッパー（vibration ripper）に係り、さらに詳しくは振動保持構造が改善された振動リッパーに関する。   The present invention relates to a vibration ripper, and more particularly to a vibration ripper having an improved vibration holding structure.

一般に、高速道路、港湾、橋梁、ダム、建築物、都市の開発などのための土木、建築現場で使用される掘削機は打撃作動、回転作動及びドリリング作動による地盤の押し固め、破砕、掘削などを行う過程において激しい騒音が発生する。   Generally, excavators used in highways, harbors, bridges, dams, buildings, urban development, etc., and excavators used at construction sites are ground compaction, crushing, excavation, etc. by hammering operation, rotation operation and drilling operation During the process, intense noise is generated.

特に、岩盤、コンクリート構造物、堅固な地盤などの掘削または地盤の土壌をかき集めるために掘削機のブームにブレーカやリッパーユニットを装着して使用するようになるが、ブレーカまたはリッパーユニットから発生する振動が直接にブームスタンドに伝達される。このような振動は騒音を引き起こすが、この騒音がブームスタンドに伝達される過程で増幅して倍加される。   In particular, the excavator boom is equipped with a breaker or ripper unit to excavate rocks, concrete structures, solid ground, etc., or to collect ground soil, but the vibration generated from the breaker or ripper unit Is transmitted directly to the boom stand. Such vibration causes noise, but is amplified and doubled in the process of transmitting this noise to the boom stand.

この点に鑑みて、韓国特許公開第２００６−００３３８９３号には掘削機用リッパーが開示されている。この掘削機用リッパーは掘削機のブームに連結される連結マウント部、該連結マウント部に掘削回転自在に装着され、地盤の土壌を掘削するためのブレード本体、それから前記ブレード本体に装着され、前記ブレード本体に振動力を提供するための振動手段とを含む。   In view of this point, Korean Patent Publication No. 2006-0033893 discloses an excavator ripper. This excavator ripper is connected to the boom of the excavator, is connected to the connecting mount portion so that excavation rotation is possible, a blade main body for excavating ground soil, and then attached to the blade main body, Vibration means for providing a vibration force to the blade body.

従来の掘削機用リッパーは掘削機のブームにブレード本体が回転自在に装着され、該ブレード本体に振動手段が設けられているので、この振動がブレード本体を介してブームに伝達される。このようにブームに伝達された振動は増幅して掘削機の調整を困難にし、ひいては掘削機を損傷させる問題点がある。   In the conventional excavator ripper, the blade body is rotatably mounted on the boom of the excavator, and the blade body is provided with vibration means, so that the vibration is transmitted to the boom via the blade body. In this way, the vibration transmitted to the boom is amplified, making it difficult to adjust the excavator, which in turn causes the problem of damaging the excavator.

そして、韓国特許公開第２０１１−０１１６６４７号には重装備用振動リッパーが開示されている。この振動リッパーは油圧モータによって回転するギアが内部に上下方向に整列されて回転自在に配され、前記それぞれのギアには偏心錘が装着されてギアの回転中に上下方向の振動を発生させる振動本体を備え、前記振動本体の下部には振動本体の長手方向にリッパーの刃を装着して地盤掘削時、振動本体がリッパーの刃に沿って地中の深いところまで挿入自在に構成される。   Korean Patent Publication No. 2011-0116647 discloses a vibration ripper for heavy equipment. In this vibration ripper, gears that are rotated by a hydraulic motor are arranged in an up and down direction so as to be freely rotatable, and an eccentric weight is attached to each of the gears to generate a vibration in the up and down direction while the gears are rotating. A main body is provided, and a ripper blade is attached to the lower portion of the vibration main body in the longitudinal direction of the vibration main body so that the vibration main body can be inserted deep into the ground along the ripper blade when excavating the ground.

本発明者は振動リッパーのダンパー及び弾性保持構造を根強く研究して特許第0878296号として登録を受けており、この振動リッパーをさらに研究し続けて後続出願を行うように至った。   The present inventor has intensively studied the damper and the elastic holding structure of the vibration ripper and has been registered as Patent No. 0878296, and has continued to research this vibration ripper and file subsequent applications.

A jaw coupling portion 101 is formed in the lower part of the ripper blade 100, and a coupling groove 106 in which the jaw coupling portion 101 is coupled is formed in the jaw 105. The key unit 110 includes a fixing member 111 held on both sides of the jaw 105 and a guide bar 112 slidably held on the jaw coupling portion 101 of the ripper blade 100 and coupled to the fixing member 111. A key member 113 and a coupling member 114 coupled to the guide rod 112 and held by the ripper blade 100 are provided, and a plurality of washers 115 are formed between the coupling members 114.

前述したように構成された本発明に係る振動リッパーの作用を説明すれば次の通りである。   The operation of the vibration ripper according to the present invention configured as described above will be described as follows.

本発明に係る振動リッパーは、土木、建築物の建設現場、撤去現場などで一般の土質より強度の高いコンクリート、アスファルト、軟質岩を破砕及び掘削する作業を行うもので、作業時騒音を最小化し、振動がブームまたはアームに伝達されることを防止できる。すなわち、本発明に係る振動リッパー１０が掘削機のブームに装着された状態で振動ユニット２０のバイブレータの油圧モータが駆動されれば、バイブレータに設けられた偏心ウェイトが回転するようになって振動が発生する。従って、振動ユニット、すなわちハウジング２１とこれに連結されるリッパーブレード１００の主な振動は上下方向に行われる。   The vibration ripper according to the present invention is a work for crushing and excavating concrete, asphalt, soft rock, which is stronger than ordinary soil, in civil engineering, building construction sites, removal sites, etc., and minimizes noise during work. , Vibration can be prevented from being transmitted to the boom or arm. That is, if the vibrator hydraulic motor of the vibration unit 20 is driven in a state where the vibration ripper 10 according to the present invention is attached to the boom of the excavator, the eccentric weight provided in the vibrator rotates and vibrations are generated. Occur. Therefore, main vibrations of the vibration unit, that is, the housing 21 and the ripper blade 100 connected thereto are performed in the vertical direction.

この過程で、前記振動ユニット２０のハウジング２１は、防振手段４０の防振部材４１、４２、すなわち弾性力を有するゴム材よりなる防振部材４１、４２によって懸架されているので、上下方向への振動に干渉を受けなくなる。特に、本発明に係る振動リッパー１０はハウジング２１と本体１３が第１連結リンク５１により連結されているので、振動の範囲を限定するようになる。 すなわち、第１連結リンク５１の長さは限定されているので、回動される範囲が限定されることから振動の幅を限定するようになる。前記第１連結リンクは２つの第１及び第２リンク部材５１ａ、５１ｂがインライン状に連結されているので、上下方向への振動自由度と左右方向への振動自由度が確保される。この自由度はリンクを連結することによる振動の増幅を軽減することができる。   In this process, the housing 21 of the vibration unit 20 is suspended by the vibration isolating members 41 and 42 of the vibration isolating means 40, that is, the vibration isolating members 41 and 42 made of a rubber material having an elastic force. No interference from vibration. In particular, the vibration ripper 10 according to the present invention limits the vibration range because the housing 21 and the main body 13 are connected by the first connection link 51. That is, since the length of the first connecting link 51 is limited, the range of rotation is limited, so that the width of vibration is limited. Since the two first and second link members 51a and 51b are connected in-line in the first connection link, the degree of freedom of vibration in the vertical direction and the degree of freedom of vibration in the left-right direction are ensured. This degree of freedom can reduce the amplification of vibration caused by connecting the links.

また、ハウジング２１の下部側と本体１３が第２連結リンク５５により連結された構造を有しているので、前述したように第１連結リンクと第２連結リンクの拘束を制御して、ブレードリッパーの作用反作用の力が防振部材にかかることを防止し、リッパーブレード１００による作業時作業力がリッパーブレード１００からハウジング２１側に伝達され、前記ハウジング２１を保持する防振部材４１、４２の損傷を防止できるようになる。すなわち、ゴム材のプレートよりなる防振部材が破裂したり耐久性が低下することを防止できる。   Further, since the lower side of the housing 21 and the main body 13 are connected by the second connecting link 55, the blade ripper is controlled by controlling the restraint between the first connecting link and the second connecting link as described above. The working force of the ripper blade 100 is transmitted from the ripper blade 100 to the housing 21 side, and the vibration isolating members 41 and 42 holding the housing 21 are damaged. Can be prevented. That is, it is possible to prevent the vibration isolating member made of a rubber material plate from being ruptured or the durability from being lowered.

そして、作業する過程で前記リッパーブレードの端部に設けられたジョー１０５はキーユニット１１０により保持されているので、直接的な衝撃または振動伝達時騒音を無くす機能を果たし、しかも消耗性部品であるジョーの取替えが容易になる。   Since the jaw 105 provided at the end of the ripper blade is held by the key unit 110 in the process of working, it functions to eliminate noise during direct impact or vibration transmission and is a consumable part. Jaw replacement is easy.

以上述べたように、本発明に係る振動リッパーは振動限定ユニットである第１及び第２連結リンクによって作業時に発生する作用反作用を制御することができるので、掘削または岩破砕作業の際に、作業力によって防振手段が損傷することを防止できる。   As described above, since the vibration ripper according to the present invention can control the action and reaction generated during the operation by the first and second connecting links which are the vibration limiting units, It is possible to prevent the vibration isolating means from being damaged by the force.

本発明は前述した特定の望ましい実施例に限定されず、請求の範囲で請求する本発明の要旨を逸脱せず当該発明の属する技術分野における通常の知識を有する者であれば誰でも多様な変形実施が可能であることは勿論、そのような変更は請求の範囲の記載の範囲内にある。   The present invention is not limited to the specific preferred embodiments described above, and various modifications can be made by anyone having ordinary knowledge in the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Such modifications are, of course, possible within the scope of the appended claims.

本発明の振動リッパーは、リッパーブレードによる掘削または破砕作業の時に、振動の振幅を防振ユニットに提供することにより耐久性を向上させたものであって、土木、建設のための各種の重装備に広く使用できる。   The vibration ripper according to the present invention has improved durability by providing vibration isolation to the vibration isolation unit during excavation or crushing work with a ripper blade, and includes various heavy equipment for civil engineering and construction. Can be used widely.
