Abstract

PROBLEM TO BE SOLVED: To provide a demolition machine capable of transporting a guard for preventing crushed pieces from falling to a cab while being installed on an articulated front without requiring a change in the attitude, whereby a labor for the transportation and assembly can be reduced.SOLUTION: This demolition machine includes an upper structure 3 installed on a lower structure 1, the cab 5 installed on the upper structure 3, and the articulated front 6 installed on the upper structure 1. The articulated front 6 includes a long boom 8 and an arm 14 for high-lift work, a relay boom 11 which is shorter than the boom 8 and the arm 14 and which is attached between the boom 8 and the arm 14 rotatably relative to each other, and a crushing device 15 attached to the distal end of the arm 14. The guard 21 for preventing the crushed pieces crushed by the crushing device 15 from falling to the cab 5 is mounted on the rear surface of the relay boom 11.

Description

本発明は、高所解体作業のため、多関節フロントとして長いブームおよびアームとこれらの間の中継ブームとを備えた解体機に係り、特にアームの先端に取付けられた破砕具による破砕作業で生じた破砕片がキャブに落下することを防止するガードの取付け構造に関する。   The present invention relates to a dismantling machine equipped with a long boom and an arm as a multi-joint front and a relay boom between them for dismantling at a high place, and particularly occurs in a crushing operation by a crushing tool attached to the tip of the arm. The present invention relates to a guard mounting structure that prevents the broken pieces from falling into the cab.

ビル等の高所解体作業を行なう場合、長い多関節フロントを有する解体機が用いられる。このような解体機として、長いブームとアームとの間に比較的短い中継ブームを設けた多関節フロントを備えたものがある（例えば特許文献１参照）。このような中継ブームを持つ多関節フロントを備えた解体機は、これを備えていないものに比較して、アームの姿勢をより広範囲に変更できることと、多関節フロントの先端の破砕具をより高所に到達可能にする点において有利である。   When performing dismantling work at high places such as a building, a dismantling machine having a long articulated front is used. As such a dismantling machine, there is one having an articulated front provided with a relatively short relay boom between a long boom and an arm (for example, see Patent Document 1). The dismantling machine equipped with an articulated front with such a relay boom can change the posture of the arm in a wider range compared to the one without this, and the crushing tool at the tip of the articulated front is higher. This is advantageous in that it can be reached.

この解体機においては、従来より、特許文献１にも開示されているように、ブームの背面に、破砕具による破砕作業で生じた破砕ブロック等の破砕片がキャブに落下することを防止するためのガードを取付けている。   In this demolition machine, as disclosed in Patent Document 1, conventionally, in order to prevent crushing pieces such as crushing blocks generated by crushing work using a crushing tool from falling on the cab on the back of the boom. The guard is installed.

特開２００８−２７２６４８号公報JP 2008-272648 A

図６は前記従来の中継ブームを有する多関節フロントを輸送姿勢状態を示す側面図である。図６において、４０は輸送用トレーラトラック、６はこのトレーラトラック４０の荷台４０ａ上に搭載された多関節フロントである。多関節フロント６は、ブーム８と、このブーム８にピン１０により回動可能に連結された中継ブーム１１と、この中継ブーム１１にピン１３により回動可能に連結されたアーム１４と、ブーム８と中継ブーム１１との間に設けられた中継ブーム回動用の油圧シリンダ９と、中継ブーム１１とアーム１４との間に設けられたアーム回動用の油圧シリンダ１２と、アーム１４の先端に取付けられる破砕具（図示せず）を回動させるためにアーム１４に取付けられた油圧シリンダ１７とを備える。４１はブーム８の背面（ブーム８の作業時における起立状態において背面となる面を意味する。）に取付けたガードであり、キャブ（図示せず）への破砕片の落下を防止するものである。   FIG. 6 is a side view showing a transport posture state of the articulated front having the conventional relay boom. In FIG. 6, reference numeral 40 denotes a transport trailer truck, and reference numeral 6 denotes an articulated front mounted on a loading platform 40 a of the trailer truck 40. The articulated front 6 includes a boom 8, a relay boom 11 that is pivotally connected to the boom 8 by a pin 10, an arm 14 that is pivotally connected to the relay boom 11 by a pin 13, and the boom 8. Are attached to the distal end of the arm 14, the hydraulic cylinder 9 for turning the relay boom provided between the relay boom 11, the hydraulic cylinder 12 for turning the arm provided between the relay boom 11 and the arm 14, and the arm 14. And a hydraulic cylinder 17 attached to the arm 14 for rotating a crushing tool (not shown). Reference numeral 41 denotes a guard attached to the rear surface of the boom 8 (meaning a surface that becomes the rear surface when the boom 8 is standing up), and prevents the shredded pieces from dropping onto the cab (not shown). .

図６に示すように、多関節フロント６の輸送の際には、ブーム８、中継ブーム１１、アーム１４をコ字形に折り曲げ、アーム１４を下にし、ブーム８は荷台４０ａ上に置いた支持台４２により支持して搭載する。このようにブーム８にガード４１を取付けた状態で輸送する場合、ガード４１は搭載状態におけるブーム８から上方に突出するので、その際の輸送高さＨ２は、ガード４１を取外した状態の高さＨ１より高くなる。その結果、このガード４１を取付けたまま多関節フロント６を荷台４０ａに搭載した状態では輸送制限高さを超えてしまう恐れがある。このため、ガード４１を取外して輸送するか、あるいは特許文献１にも記載のように、ガード４１の取付け姿勢を４１Ａで示す低い姿勢に変え、これにより、ガード４１を使用姿勢で取付けた状態の輸送高さＨ２よりも低い輸送高さＨ３にして輸送することが行なわれている。   As shown in FIG. 6, when the articulated front 6 is transported, the boom 8, the relay boom 11, and the arm 14 are folded into a U-shape, the arm 14 is placed downward, and the boom 8 is placed on the loading platform 40a. 42 is supported and mounted. Thus, when transporting with the guard 41 attached to the boom 8, the guard 41 protrudes upward from the boom 8 in the mounted state, so the transport height H2 at that time is the height when the guard 41 is removed. It becomes higher than H1. As a result, in the state where the multi-joint front 6 is mounted on the loading platform 40a with the guard 41 attached, there is a risk of exceeding the transport limit height. For this reason, the guard 41 is removed and transported or, as described in Patent Document 1, the mounting posture of the guard 41 is changed to a low posture shown by 41A, and thus the guard 41 is mounted in a working posture. Transportation is carried out at a transportation height H3 lower than the transportation height H2.

このように、従来のガード４１付きの多関節フロント６を有する解体機においては、輸送にあたり、ガード４１を取外すかあるいは低姿勢にし、現地において再度取付けるか、あるいは低姿勢から使用姿勢に変更する必要があり、輸送および組立に手間がかかるという問題点があった。   As described above, in the dismantling machine having the conventional articulated front 6 with the guard 41, it is necessary to remove the guard 41 or change it to a low position and reattach it on site or change it from a low position to a use position for transportation. There is a problem that it takes time and labor for transportation and assembly.

本発明は、上記問題点に鑑み、破砕片回避用のガードを多関節フロントに設けた解体機において、ガードを多関節フロントに取付けたままでしかも姿勢変更を行なう必要なく輸送することができ、もって輸送および組立における手間を削減できる構成のものを提供することを目的とする。   In view of the above problems, the present invention provides a dismantling machine provided with a guard for avoiding shatter pieces on the articulated front, and can be transported without changing the posture while the guard is attached to the articulated front. An object of the present invention is to provide a configuration that can reduce labor in transportation and assembly.

本発明の解体機は、下部走行体上に設置された上部旋回体と、前記上部旋回体上に設置されたキャブと、前記上部旋回体に取付けられる多関節フロントとを備え、
前記多関節フロントは、高所作業を可能とするための長いブームおよびアームと、前記ブームおよび前記アームより短く、前記ブームと前記アームとの間に相対回動可能に取付けられる中継ブームと、前記アームの先端に取付けられる破砕具とを備えた解体機において、
前記中継ブームの背面に、前記破砕具により破砕された破砕片の前記キャブへの落下を防止するガードを取付けたことを特徴とする。 The demolition machine of the present invention comprises an upper swing body installed on a lower traveling body, a cab installed on the upper swing body, and an articulated front attached to the upper swing body,
The articulated front includes a long boom and an arm for enabling work at a high place, a relay boom that is shorter than the boom and the arm and is attached to the boom and the arm so as to be relatively rotatable, and In a demolition machine equipped with a crushing tool attached to the tip of the arm,
The back of the relay boom is provided with a guard for preventing the crushed pieces crushed by the crushing tool from falling onto the cab.

本発明によれば、中継ブームの背面にガードを取付けたので、ブーム、アームを横向きにしかつ中継ブームをほぼ縦向きにして輸送する場合、ガードが多関節フロントの上面に突出しない。このため、輸送時の姿勢では、ガードを多関節フロントに取付けた状態であっても多関節フロントの輸送状態では高さが変わらない。その結果、多関節フロントの輸送時の高さを輸送制限高さ未満とするためにガードを着脱したり、ガードの取付け姿勢を変更する必要が無くなり、輸送および組立における手間が削減できる。   According to the present invention, since the guard is attached to the rear surface of the relay boom, the guard does not protrude from the upper surface of the multi-joint front when transporting the boom and arm horizontally and the relay boom substantially vertically. For this reason, in the posture at the time of transportation, even if the guard is attached to the articulated front, the height does not change in the transportation state of the articulated front. As a result, it is not necessary to attach or detach the guard or change the mounting posture of the guard in order to make the height of the articulated front when transporting less than the transport limit height, thereby reducing labor in transportation and assembly.

また、ガードを中継ブームに取付けたので、従来のようにブームに取付けた場合に比較してガードの位置が高くなり、その結果、破砕片の落下をカバーしうる範囲が広くなり、ガードを従来よりも小型化することができる。   In addition, since the guard is attached to the relay boom, the position of the guard becomes higher compared to the case where it is attached to the boom as in the conventional case. Can be made smaller.

In this dismantling machine, an upper swing body 3 is installed on a lower traveling body 1 via a swing device 2, and a hydraulic power unit 4 and a cab 5 as a hydraulic power source device are installed on the upper swing body 3, and an upper swing body. An articulated front 6 is attached to 3. The articulated front 6 includes a boom 8 attached to the upper swing body 3 by a hydraulic cylinder 7 so as to be able to be raised and lowered, and a relay boom 11 attached to the tip of the boom 8 so as to be rotatable around a pin 10 by a hydraulic cylinder 9. An arm 14 is provided at the tip of the relay boom 11 so as to be pivotable about a pin 13 by a hydraulic cylinder 12. As shown in the figure, the boom 8 and the arm 14 are formed longer than a general boom and arm used for a hydraulic excavator or the like so that the dismantling work at a high place is possible, and the relay boom 11 is longer than the boom 8 and the arm 14. Formed short.

アーム１４の先端には油圧シリンダ（図示せず）により開閉される鋏状の破砕爪１５ａを有する破砕具１５が、ピン１６を中心に回動可能に取付けられる。１７は破砕具１５を回動させるためにアーム１４の背面に一端を取付けた油圧シリンダである。この油圧シリンダ１７の他端は、アーム１４に枢着したリンク１８と、破砕具１５に枢着したリンク１９に共通にピン連結される。   A crushing tool 15 having a hook-like crushing claw 15 a that is opened and closed by a hydraulic cylinder (not shown) is attached to the tip of the arm 14 so as to be rotatable about a pin 16. Reference numeral 17 denotes a hydraulic cylinder having one end attached to the back surface of the arm 14 for rotating the crushing tool 15. The other end of the hydraulic cylinder 17 is pin-connected to a link 18 pivotally attached to the arm 14 and a link 19 pivotally attached to the crushing tool 15.

ブーム８は１本の長いもので構成する場合もあるが、本実施の形態においては、上部旋回体３に油圧シリンダ７により俯仰可能に取付けられる基端ブーム８ａと、作業箇所の高さに応じて継ぎ足し本数を調整してピン２０により継ぎ足す１本以上の継ぎ足しブーム８ｂと、この継ぎ足しブーム８ｂの最先端にピン２０により着脱可能に取付けられる先端ブーム８ｃとからなる例について示している。中継ブーム１１を回動させる油圧シリンダ９の一端は、この先端ブーム８ｃに連結される。   In some cases, the boom 8 may be constituted by a single long one. In the present embodiment, the boom 8a is attached to the upper swing body 3 by a hydraulic cylinder 7 so that the boom 8 can be raised and lowered, and the height of the work location. An example is shown in which one or more additional booms 8b that are added by pins 20 after adjusting the number of additional lines, and a tip boom 8c that is detachably attached by pins 20 to the foremost end of the additional boom 8b. One end of the hydraulic cylinder 9 for rotating the relay boom 11 is connected to the tip boom 8c.

２１は中継ブーム１１の背面（作業中に中継ブーム１１が起立した状態において背面となる面という意味である。）に取付けたガードである。このガード２１は、破砕具１５により破砕されてアーム１４上を転動するコンクリートブロック等の破砕片を中継ブーム１１の側方に逸らせ、これにより破砕片がキャブ５上に落下することを防止するために設けられる。   Reference numeral 21 denotes a guard attached to the back surface of the relay boom 11 (which means a surface that becomes the back surface when the relay boom 11 stands during operation). The guard 21 deflects a crushed piece such as a concrete block that is crushed by the crushing tool 15 and rolls on the arm 14 to the side of the relay boom 11, thereby preventing the crushed piece from falling onto the cab 5. To be provided.

図２はガード２１の取付け構造を示す側面図、図３はその背面図である。図２、図３において、２２はブーム８に中継ブーム１１を取付けるピン１０を挿着するボス、２３は中継ブーム１１にアーム１４を取付けるピン１３を挿着するボスである。２４は中継ブーム１１の前面に固着したブラケットであり、このブラケット２４は、中継ブーム１１を回動させる油圧シリンダ９の先端をピン付けするピン孔２４ａと、アーム１４を回動させる油圧シリンダ１２の基端をピン付けするピン孔２４ｂとを有する。   FIG. 2 is a side view showing a mounting structure of the guard 21, and FIG. 3 is a rear view thereof. 2 and 3, 22 is a boss for inserting the pin 10 for attaching the relay boom 11 to the boom 8, and 23 is a boss for inserting the pin 13 for attaching the arm 14 to the relay boom 11. Reference numeral 24 denotes a bracket fixed to the front surface of the relay boom 11. The bracket 24 includes a pin hole 24 a for pinning the tip of the hydraulic cylinder 9 that rotates the relay boom 11 and a hydraulic cylinder 12 that rotates the arm 14. And a pin hole 24b for pinning the base end.

２５は中継ブーム１１の背面に固着した板状のガード取付け用ブラケットである。２６はガード２１の下面（下面とは中継ブーム１１が垂直姿勢をとる際に下になる面を意味する。）に固着した平行板状のブラケットである。ガード２１の中継ブーム１１への取付けは、この平行板状のブラケット２６で中継ブーム１１に固着したブラケット２５で挟んで嵌合し、これらのブラケット２５，２６に設けたボルト挿通孔（図示せず）にボルト２７を挿通し、このボルト２７にナット２８を螺合して締結することにより行なわれる。図３、図４に示すように、ガード２１は、中継ブーム１１の起立状態において、左右方向の片側（本例では右側）が他側（本例では左側）よりも高くなる姿勢で取付けられる。このように傾斜させる理由は、ガード２１上に落下した破砕片を中継ブーム１１の側方に滑落させるためである。   Reference numeral 25 denotes a plate-like guard mounting bracket fixed to the back surface of the relay boom 11. Reference numeral 26 denotes a parallel plate-shaped bracket fixed to the lower surface of the guard 21 (the lower surface means a surface that is lowered when the relay boom 11 is in a vertical posture). The guard 21 is attached to the relay boom 11 by being sandwiched and fitted between brackets 25 fixed to the relay boom 11 with the parallel plate-shaped brackets 26 and bolt insertion holes (not shown) provided in these brackets 25 and 26. ) Is inserted into the bolt 27 and a nut 28 is screwed into the bolt 27 and fastened. As shown in FIGS. 3 and 4, the guard 21 is attached in a posture in which one side in the left-right direction (right side in this example) is higher than the other side (left side in this example) in the standing state of the relay boom 11. The reason for inclining in this way is to cause the crushed pieces falling on the guard 21 to slide down to the side of the relay boom 11.

図４はこの解体機の多関節フロント６の輸送状態を示す側面図である。この例ではブーム８は基端ブーム８ａを継ぎ足しブーム８ｂから分離し、継ぎ足しブーム８ｂに先端ブーム８ｃを連結したままで輸送している状態を示す。輸送の際には、前記従来例と同様に、アーム１４を下にし、ブーム８を上にし、中継ブーム１１を縦にし、ブーム８を支持台４２により支持し、コの字形にした姿勢でトレーラトラック４０の荷台４０ａ上に多関節フロント６を搭載する。また、破砕具１５はアーム１４から取外した状態で輸送する。   FIG. 4 is a side view showing a transportation state of the articulated front 6 of the dismantling machine. In this example, the boom 8 is connected to the base boom 8a and separated from the boom 8b, and the boom 8 is transported with the tip boom 8c connected to the boom 8b. At the time of transportation, as in the conventional example, the arm 14 is down, the boom 8 is up, the relay boom 11 is vertical, the boom 8 is supported by the support base 42, and the trailer is in a U-shaped posture. The articulated front 6 is mounted on the loading platform 40a of the truck 40. The crushing tool 15 is transported in a state where it is detached from the arm 14.

このように、トレーラトラック４０に多関節フロント６を搭載した状態においては、作業時には背面となる中継ブーム１１の面が前向きとなるので、この面に取付けられたガード２１は輸送姿勢における高さに影響を与えない。すなわち、この輸送姿勢における多関節フロント６の高さＨ１は、ガード２１による影響を受けず、輸送制限高さを考慮してガード２１を取外す必要がない。このため、輸送に当たってガード２１を中継ブーム１１から取外したり、現地においてガード２１を中継ブーム１１に取付ける必要がなく、また、輸送、組立に当たり、ガード２１の姿勢変更作業を行なう必要がなくなり、輸送および組立における手間が削減できる。   In this way, in the state where the articulated front 6 is mounted on the trailer truck 40, the surface of the relay boom 11 which is the back surface at the time of work is directed forward, so the guard 21 attached to this surface is at a height in the transportation posture. Does not affect. That is, the height H1 of the articulated front 6 in this transport posture is not affected by the guard 21, and it is not necessary to remove the guard 21 in consideration of the transport limit height. For this reason, it is not necessary to remove the guard 21 from the relay boom 11 during transportation, or to attach the guard 21 to the relay boom 11 at the site, and it is not necessary to change the posture of the guard 21 during transportation and assembly. Time and effort in assembly can be reduced.

図５はこの実施の形態のガード２１による破砕片の落下回避範囲と従来のガード５１の破砕片の落下回避範囲とを対比して示す背面図である。線３１，３２間で挟まれる領域が本実施の形態のガード２１による破砕片の落下回避範囲であり、線３３，３４間で挟まれる領域が従来のガード４１による破砕片の落下回避範囲である。図５から分かるように、本実施の形態のガード２１による場合、ガード２１の位置が従来のガード４１より高くなるので、ガード２１による線３１，３２間の破砕片の落下回避範囲が従来のガード４１による場合よりも広くなる。換言すれば、本実施の形態のガード２１の左右の幅を従来のガード４１の左右の幅よりも小さくしても、ガード４１と同等の落下回避範囲が得られるので、ガード２１の小型化が可能となる。   FIG. 5 is a rear view showing the fall avoidance range of the shredded pieces by the guard 21 of this embodiment and the fall avoidance range of the shredded pieces of the conventional guard 51 in comparison. A region sandwiched between the lines 31 and 32 is a fall avoidance range of the shredded pieces by the guard 21 of the present embodiment, and a region sandwiched between the lines 33 and 34 is a fall avoidance range of the shredded pieces by the conventional guard 41. . As can be seen from FIG. 5, in the case of the guard 21 of the present embodiment, the position of the guard 21 is higher than that of the conventional guard 41, so that the fall avoidance range of the fragments between the lines 31 and 32 by the guard 21 is the conventional guard. It becomes wider than the case of 41. In other words, even if the left and right widths of the guard 21 of the present embodiment are made smaller than the left and right widths of the conventional guard 41, a fall avoidance range equivalent to the guard 41 can be obtained. It becomes possible.

以上本発明を一実施の形態により説明したが、本発明を実施する場合、多関節フロント６の構成やガード２１の構成あるいは取付け構造は、上記実施の形態に限らず、本発明の要旨を逸脱しない範囲において、種々に変更可能である。   Although the present invention has been described above with reference to an embodiment, when the present invention is implemented, the configuration of the articulated front 6 and the configuration or mounting structure of the guard 21 are not limited to the above embodiments, and depart from the gist of the present invention. Various modifications can be made without departing from the scope.
