Description

この発明は、建設機械のキャブ内に設けたコンソールボックスに関するものである。更に、具体的には、コンソールボックスに設けられる種々の操作装置、特に、チルト角度調節装置に関する技術である。 The present invention relates to a console box provided in a cab of a construction machine. More specifically, the present invention relates to various operation devices provided in the console box, in particular, a technique related to a tilt angle adjusting device.

油圧ショベル等の建設機械には、運転席の左右側方にコンソールボックスを配置し、このコンソールボックスの上側面に作業機の操作や旋回等の操作をするための操作レバーを設けている。オペレータが運転席に乗降する際や、オペレータが乗車していないときに、誤って操作レバーに触れても作業機等が突然動き出すことがないように油圧回路等を遮断するロック装置を設けて安全性を図っている。しかし、オペレータがロック装置のロック操作を忘れて降車した場合には上記の不都合が生じかねない。   In construction machines such as hydraulic excavators, a console box is arranged on the left and right sides of a driver's seat, and an operation lever for operating a work machine, turning, and the like is provided on the upper side of the console box. When the operator gets in and out of the driver's seat or when the operator is not in the vehicle, it is safe to install a lock device that shuts off the hydraulic circuit etc. so that the work implement etc. will not suddenly move even if it touches the operation lever accidentally I am trying sex. However, if the operator forgets to lock the locking device and gets off the vehicle, the above inconvenience may occur.

そこで、オペレータがロック装置のロックを忘れることがないように、オペレータの乗降通路にゲートバーを設け、このゲートバーの操作とロック装置を連動させて、オペレータが降車するときはゲートバーを開放して、ロック装置をロックし、オペレータが運転席にいるときはゲートバーを閉鎖すると共に操作が可能となるようにロックを解除するようにしている。   Therefore, to prevent the operator from forgetting to lock the lock device, a gate bar is provided in the operator's getting-on / off passage, and when the operator gets off, the gate bar is opened and locked when the operation of the gate bar is interlocked with the lock device. The device is locked, and when the operator is in the driver's seat, the gate bar is closed and the lock is released so that the operation can be performed.

乗降通路はオペレータの運転席の前方に設けられるが、建設機械のキャブには余分なスペースが狭いので、ゲートバーを開放しただけでは、乗降通路を十分に広く取ることはできないケースもある。そこで、オペレータの乗降を容易にするためにコンソールボックスに跳ね上げ機構を設けて、作業位置と跳ね上げ位置とに操作可能にしている。また、オペレータの体格や好みに合わせて操作をしやすくするために作業位置におけるコンソールボックスのチルト角度を調節可能にして、オペレータが適宜選択可能にした装置もある。 The entrance / exit passage is provided in front of the operator's driver's seat. However, since the extra space is small in the cab of the construction machine, there are cases where the entrance / exit passage cannot be made sufficiently wide simply by opening the gate bar. Therefore, in order to make it easy for the operator to get on and off, a console box is provided with a flip-up mechanism so that it can be operated between the working position and the flip-up position. In addition, there is also an apparatus that allows the operator to select the tilt angle of the console box at the work position so that the operator can select it appropriately in order to facilitate the operation according to the physique and preference of the operator.

例えば、特許文献１に開示されている建設機械の跳ね上げ装置は、コンソールフレームのキャビン前端面に溝状係止部を設け、跳ね上げレバーを水平軸回りに回動自在に軸支し、跳ね上げレバーの先端部に係止部と係脱する係合部とから構成されている。ここで、係止部はオペレータの体格、好みに合わせて選択自在とするために係止部を上下に所定間隔で複数（例えば４個）を形成してもよい。この装置において、跳ね上げレバーを所定方向に倒回するとコンソールフレームが跳ね上げ位置に回動される。逆に跳ね上がったコンソールフレームを押し下げてロック位置に回動するとロック位置で跳ね上げレバーの係合部が係止部に係合し、下部フレームにコンソールフレームが固定される。
公開特許公報、特開２０００−３２８６０５、建設機械の安全装置 For example, a flip-up device for a construction machine disclosed in Patent Document 1 is provided with a groove-like locking portion on the front end surface of a cabin of a console frame, and a flip-up lever is pivotally supported around a horizontal axis, It is comprised from the engaging part which engages / disengages in a front-end | tip part of a raising lever. Here, a plurality of (for example, four) locking portions may be formed vertically at predetermined intervals so that the locking portions can be selected according to the physique and preference of the operator. In this apparatus, when the flip-up lever is turned in a predetermined direction, the console frame is rotated to the flip-up position. Conversely, when the console frame that has been bounced up is pushed down and rotated to the lock position, the engagement portion of the bounce lever is engaged with the locking portion at the lock position, and the console frame is fixed to the lower frame.

さらに、軸２１にはコンソールボックス１２のチルト角度を調節するチルト調節レバー３０が回動可能に設けられている。チルト調節レバー３０はゲート操作レバー２０とは独立して回動する。チルト調節レバー３０は、図５（Ａ）、（Ｂ）に示すように、頭部に把手３１を有し、略中央に軸２１と嵌合し、回動する筒部３２を有し、下端部には固定フレーム１１の係止部１８（１８ａ〜１８ｄ）と係止する係止ピン３３を有し、連結部材３４、３５によって固設連結されている。なお、チルト調節レバー３０の係止ピン３３は反時計方向にばね４１により付勢されている。 Further, a tilt adjusting lever 30 for adjusting the tilt angle of the console box 12 is rotatably provided on the shaft 21. The tilt adjustment lever 30 rotates independently of the gate operation lever 20. As shown in FIGS. 5A and 5B, the tilt adjustment lever 30 has a handle 31 at the head, a cylindrical portion 32 that fits the shaft 21 at the center and rotates, and has a lower end. This portion has a locking pin 33 that locks with the locking portion 18 (18a to 18d) of the fixed frame 11, and is fixedly connected by connecting members 34 and 35. The locking pin 33 of the tilt adjustment lever 30 is urged by the spring 41 in the counterclockwise direction.

また、固定フレーム１１の係止部１８（１８ａ〜１８ｄ）と同様な形状の係止部３６（３６ａ〜３６ｄ）を有する解除プレート４０が以下のように構成されている。図６は解除プレート４０の構成を示す。（Ａ）は正面図、（Ｂ）は側面図を示す。解除プレート４０は図６に示すように、板部材から構成され、上部にはゲート操作レバー２０の突起ピン２３と嵌合する長穴形状の溝３７を有し、中央部にはゲート操作レバー２０の下端の突起ピン２５と嵌合する長穴形状の溝３８を有し、中央左辺縁に複数の切欠溝３６ａ〜３６ｄからなる係止部３６が設けられている。係止部３６並びに溝３７及び溝３８は突起ピン２３、２５が溝３７及び溝３８に夫々嵌合したときに、それらの中心線が軸１３の中心を中心点とする円弧に形成するのが好ましい。また、下部には固定フレーム１１のガイドピン１９と嵌合するガイド溝３９が設けられている。ガイド溝３９は略水平な第１ガイド溝３９ａと略垂直な第２ガイド溝３９ｂを連結したＬ字形状に形成される。即ち、図１に示したような作業位置にある状態で、第１ガイド溝３９ａはゲート操作レバー２０の突起ピン２３を中心とする円弧からなり、第２ガイド溝３９ｂは軸孔１６（軸１３）を中心とする円弧から構成し、両方の円弧の中心線の交点３９ｃで連結されている。 Further, the release plate 40 having the locking portions 36 (36a to 36d) having the same shape as the locking portions 18 (18a to 18d) of the fixed frame 11 is configured as follows. FIG. 6 shows the configuration of the release plate 40. (A) is a front view and (B) is a side view. As shown in FIG. 6, the release plate 40 is formed of a plate member, and has an elongated hole-shaped groove 37 that fits with the protruding pin 23 of the gate operation lever 20 in the upper portion, and the gate operation lever 20 in the center portion. And a locking portion 36 including a plurality of cutout grooves 36a to 36d is provided on the left edge of the center. The engaging portion 36 and the grooves 37 and 38 are formed in an arc whose center line is centered on the center of the shaft 13 when the projecting pins 23 and 25 are fitted in the grooves 37 and 38, respectively. preferable. A guide groove 39 that fits with the guide pin 19 of the fixed frame 11 is provided at the lower portion. The guide groove 39 is formed in an L shape that connects a substantially horizontal first guide groove 39a and a substantially vertical second guide groove 39b. That is, in the state as shown in FIG. 1, the first guide groove 39 a is an arc centered on the projection pin 23 of the gate operation lever 20, and the second guide groove 39 b is the shaft hole 16 (the shaft 13). ) At the intersection 39c of the center lines of both arcs.

解除プレート４０は上記構成により、溝３７に突起ピン２３が嵌合し、溝３８に突起ピン２５が嵌合している。従って、ゲート操作レバー２０の回転する動きによって解除プレートの係止部３６（３６ａ〜３６ｄ）の姿勢（位置と回転角度）並びにガイド溝３９の姿勢（位置と回転角度）が変化する。図１は解除プレートの係止部３６（３６ａ〜３６ｄ）の姿勢が固定フレーム１１の係止部１８（１８ａ〜１８ｄ）と一致した場合で、ゲート操作レバー２０の把手２２が図１の状態（Ｂ）にある場合、即ちコンソールボックス１２が作業状態の位置にある場合を示す。 With the above-described configuration, the release plate 40 has the projection pin 23 fitted in the groove 37 and the projection pin 25 fitted in the groove 38. Accordingly, the posture (position and rotation angle) of the release plate locking portion 36 (36a to 36d) and the posture (position and rotation angle) of the guide groove 39 are changed by the rotation of the gate operation lever 20. 1 shows the case where the position of the locking portion 36 (36a to 36d) of the release plate matches the locking portion 18 (18a to 18d) of the fixed frame 11, and the handle 22 of the gate operating lever 20 is in the state shown in FIG. The case where it exists in B), ie, the case where the console box 12 exists in the position of a working state is shown.

また、ゲートバー４２は、図１に示すように、コンソールボックス１２の前方に設けられた乗降用通路を遮断（図示省略）及び開放（実線位置）ができるように、コンソールボックス１２の前端部に軸４３により回動可能に設けられている。ゲートバー４２の上端部に設けられたピン孔４４が連結部材４５を介してゲート操作レバー２０のピン孔２４とピン連結されている。さらに、ゲートバー４２が遮断位置と開放位置の何れかの位置で止まるように、連結部材４５とゲートバー４２との間に引っ張りばね４６を設けて付勢している。 Further, as shown in FIG. 1, the gate bar 42 is pivoted at the front end of the console box 12 so that the boarding / alighting passage provided in front of the console box 12 can be blocked (not shown) and opened (solid line position). 43 is rotatably provided. A pin hole 44 provided at the upper end of the gate bar 42 is pin-connected to the pin hole 24 of the gate operation lever 20 via a connecting member 45. Further, a tension spring 46 is provided between the connecting member 45 and the gate bar 42 so as to stop the gate bar 42 at either the blocking position or the open position.

以上に述べた構成により、本実施形態の装置は以下のように機能する。まず、コンソールボックス１２のチルト角度を調節する場合は以下の手順で行う。最初に、図１に示す作業位置で、チルト調節レバー３０を時計方向に回動させて係止ピン３３を固定フレーム１１の係止部１８（例えば、１８ｃ）から外す。この場合、係止ピン３３は同時に解除プレート４０の係止部３６（例えば、３６ｃ）からも外れる。係止ピン３３が外れた状態では、ゲート操作レバー２０の突起ピン２３と突起ピン２５が同時に解除プレート４０の長穴形状の溝３７及び３８を動ける範囲でコンソールボックスの揺動及びそれに伴うチルト調節レバー３０の動きが自由になる。一方、解除プレート４０の第１ガイド溝３９ａが固定フレーム４０の第１ガイド溝３９ａが固定フレーム１１のガイドピン１９に当接して動きが制限されるため、解除プレート４０は位置、角度が変化せず係止部１８（例えば、１８ｃ）と係止部３６（例えば、３６ｃ）は一致している。従って、コンソールボックス１２のチルト角度を好みの角度に選択した後にチルト調節レバー３０を反時計方向に回動させて係止ピン３３を固定フレーム１１の係止部１８（例えば、１８ｂ）及び係止部３６（例えば、３６ｂ）に係止させることによりチルト角度の調節が可能になる。 With the configuration described above, the apparatus of the present embodiment functions as follows. First, when the tilt angle of the console box 12 is adjusted, the following procedure is performed. First, at the working position shown in FIG. 1, the tilt adjustment lever 30 is rotated clockwise to remove the locking pin 33 from the locking portion 18 (for example, 18 c) of the fixed frame 11. In this case, the locking pin 33 is also released from the locking portion 36 (for example, 36c) of the release plate 40 at the same time. In a state where the locking pin 33 is released, the console box is swung and the tilt is adjusted in the range in which the protruding pin 23 and the protruding pin 25 of the gate operation lever 20 can simultaneously move the elongated holes 37 and 38 of the release plate 40. The movement of the lever 30 becomes free. On the other hand, since the movement of the first guide groove 39a of the release plate 40 is restricted by the first guide groove 39a of the fixed frame 40 coming into contact with the guide pin 19 of the fixed frame 11, the position and angle of the release plate 40 change. The locking portion 18 (for example, 18c) and the locking portion 36 (for example, 36c) are coincident with each other. Therefore, after the tilt angle of the console box 12 is selected to a desired angle, the tilt adjusting lever 30 is rotated counterclockwise to lock the locking pin 33 with the locking portion 18 (for example, 18b) of the fixed frame 11 and the locking pin 33. The tilt angle can be adjusted by engaging with the portion 36 (for example, 36b).

次に、ゲートバー４２を遮断位置に回動させるには、図７に示すように、ゲート操作レバー２０の把手２２を（Ｂ）状態から前方に倒して（Ａ）状態にする。これによって、ゲート操作レバー２０の板状部材２０ａがピン２３（軸２１）の回りに回転し、連結部材４５が後方に引かれ、ゲートバー４２が時計方向に回動し、乗降通路を遮断する。この場合にチルト調節レバー３０の係止ピン３３は固定フレーム１１の係止部１８（例えば１８ｃ）と係止した状態を保持し、解除プレート４０はゲート操作レバー２０の下端突起ピン２５が解除プレート４０の溝３８の原位置に嵌合したまま回転する。従って、ゲート操作レバー２０を元の位置（Ｂ）に戻すと、解除プレート４０は原位置に戻り、チルト調節レバー３０の係止ピン３３は解除プレート４０の係止部３６の原切欠溝（例えば３６ｃ）と係止する。 Next, in order to rotate the gate bar 42 to the blocking position, as shown in FIG. 7, the handle 22 of the gate operation lever 20 is tilted forward from the (B) state to the (A) state. As a result, the plate-like member 20a of the gate operating lever 20 rotates around the pin 23 (shaft 21), the connecting member 45 is pulled rearward, the gate bar 42 rotates clockwise, and the entrance / exit passage is blocked. In this case, the locking pin 33 of the tilt adjustment lever 30 is held in a locked state with the locking portion 18 (for example, 18c) of the fixed frame 11, and the release plate 40 is connected to the lower end protrusion pin 25 of the gate operation lever 20 by the release plate. It rotates while fitted in the original position of 40 grooves 38. Therefore, when the gate operation lever 20 is returned to the original position (B), the release plate 40 returns to the original position, and the locking pin 33 of the tilt adjustment lever 30 is moved to the original notch groove (for example, the locking portion 36 of the release plate 40). 36c).

次に、ゲート操作レバー２０の把手２２を図１の（Ｃ）方向（時計方向）に回動するとコンソールボックス１２は、図８に示すように跳ね上がる。図９（Ａ）は完全に跳ね上がる前の経過説明図で、図９（Ｂ）は完全に跳ね上げた後で、元の位置に戻すときの途中経過説明図である。 Next, when the handle 22 of the gate operation lever 20 is rotated in the (C) direction (clockwise) in FIG. 1, the console box 12 jumps up as shown in FIG. FIG. 9 (A) is a progress explanatory diagram before completely jumping up, and FIG. 9 (B) is a progress explanatory diagram when returning to the original position after completely jumping up.

コンソールボックス１２を跳ね上げる前はチルト調節レバー３０の係止ピン３３は固定フレーム１１の係止部１８（例えば１８ｃ）及び解除プレート４０の係止部（例えば３６ｃ）と係止した状態にある。この状態で把手２２を（Ｃ）方向（時計方向）に回動し始めると、図９（Ａ）に示すように、解除プレート４０もゲート操作レバー２０の板状部材２０ａと一緒になって回動を始める。これはチルト調節レバー３０の係止ピン３３が解除プレート４０の係止部（例えば３６ｃ）と係止した状態にあるため、ゲート操作レバー２０の突起ピン２３及び突起ピン２５は解除プレート４０の溝３７及び溝３８の同じ位置（原位置）のまま解除プレート４０が回転する。この回転によって、係止ピン３３と固定フレーム１１の係止部１８（例えば１８ｃ）の係止が外れ、固定フレーム１１のガイドピン１９は第１ガイド溝３９ａとの関係で相対的に右へ移動して交点３９ｃまで来る。ガイドピン１９が交点３９ｃに来ると、ばね１４の付勢力により、コンソールボックス１２は跳ね上がり、図８に示す状態になる。なお、この状態では固定フレーム１１のガイドピン１９が解除プレート４０の第２ガイド溝３９ｂの下端部に当接して動きが抑制されるため、ゲート操作レバー２０を操作（回動）することはできない。 Before the console box 12 is flipped up, the locking pin 33 of the tilt adjustment lever 30 is locked with the locking portion 18 (for example, 18c) of the fixed frame 11 and the locking portion (for example, 36c) of the release plate 40. When the handle 22 starts to rotate in the (C) direction (clockwise) in this state, the release plate 40 also rotates together with the plate-like member 20a of the gate operation lever 20 as shown in FIG. Start moving. This is because the locking pin 33 of the tilt adjusting lever 30 is locked with the locking portion (for example, 36 c) of the release plate 40, so that the projection pin 23 and the projection pin 25 of the gate operation lever 20 are grooves of the release plate 40. The release plate 40 rotates with the same position (original position) of 37 and the groove 38. By this rotation, the locking pin 33 and the locking portion 18 (for example, 18c) of the fixed frame 11 are unlocked, and the guide pin 19 of the fixed frame 11 moves to the right relative to the first guide groove 39a. Then come to the intersection 39c. When the guide pin 19 comes to the intersection 39c, the console box 12 jumps up by the urging force of the spring 14, and the state shown in FIG. In this state, since the guide pin 19 of the fixed frame 11 abuts on the lower end portion of the second guide groove 39b of the release plate 40 and the movement is suppressed, the gate operation lever 20 cannot be operated (turned). .

図８の状態からコンソールボックス１２の前方部を押し下げるか、又は、ゲート操作レバー２０を操作してコンソールボックス１２を一体回動させると、ガイドピン１９は第２ガイド溝３９ｂとの関係で相対的に上方へ移動しながら交点３９ｃまで来る。係止ピン３３が解除プレート４０の係止部３６（例えば３６ｃ）と係止した状態にあるため、ゲート操作レバー２０及び解除プレート４０は一体として回動する。従って、ガイドピン１９が交点３９ｃに来るまでは、即ちガイドピン１９が、図９（Ｂ）に示すように第２ガイド溝３９ｂにある間ゲート操作レバー２０及び解除プレート４０は反時計方向に回動できない。ガイドピン１９が交点３９ｃにきたとき、係止ピン３３は固定フレーム１１の係止部１８に対して元の切欠溝（１８ｃ）と係止する位置に戻り、ばねの付勢力により。係止ピン３３が元の切欠溝（１８ｃ）と係止し、図１に示した状態に戻る。   When the front portion of the console box 12 is pushed down from the state shown in FIG. 8 or the console box 12 is integrally rotated by operating the gate operation lever 20, the guide pin 19 is relative to the second guide groove 39b. To the intersection 39c while moving upward. Since the locking pin 33 is locked with the locking portion 36 (for example, 36c) of the release plate 40, the gate operation lever 20 and the release plate 40 rotate as a unit. Therefore, until the guide pin 19 reaches the intersection 39c, that is, while the guide pin 19 is in the second guide groove 39b as shown in FIG. 9B, the gate operation lever 20 and the release plate 40 rotate counterclockwise. I can't move. When the guide pin 19 comes to the intersection 39c, the locking pin 33 returns to the position where the locking pin 18 is locked with the original notch groove (18c) with respect to the locking portion 18 of the fixed frame 11, and by the biasing force of the spring. The locking pin 33 is locked with the original notch groove (18c), and the state shown in FIG. 1 is restored.

また、ゲート操作レバー２０が図１に示す状態（Ｂ）にあるときに作業機械がロックされるように構成した場合、例えば当接板（図示省略）をゲート操作レバー２０に設けて、ゲート操作レバー２０が図１に示す状態（Ｂ）になったときにリミットスイッチ（図示省略）がオフになってロックされる構成を設けた場合は、以下の様に機能する。即ち、ゲート操作レバー２０の把手２２の操作により、図１に示したコンソールボックス１２が作業位置にあり、且つゲートバー４２が開放位置にあって作業機械の操作がロックされた第２状態（把手２２が（Ｂ）にある状態）と、図７に示すコンソールボックス１２が作業位置にあり、且つゲートバー４２が遮断位置にあり、作業機械の操作が可能な第１状態（把手２２が（Ａ）にある状態）と、図８に示すコンソールボックス１２が跳ね上げ位置にあり、且つゲートバー４２が開放位置にあり、作業機械の操作がロックされた第３状態（把手２２が（Ｃ）にある状態）とに切り替えることができる。 When the work machine is configured to be locked when the gate operation lever 20 is in the state (B) shown in FIG. 1, for example, a contact plate (not shown) is provided on the gate operation lever 20 so as to operate the gate. When a configuration is provided in which the limit switch (not shown) is turned off and locked when the lever 20 is in the state (B) shown in FIG. 1, the following functions. That is, by the operation of the handle 22 of the gate operation lever 20, the console box 12 shown in FIG. 1 is in the working position and the gate bar 42 is in the open position and the operation of the work machine is locked (the handle 22). 7 (B)), the console box 12 shown in FIG. 7 is in the working position, and the gate bar 42 is in the blocking position, so that the work machine can be operated (the handle 22 is in (A)). 8) and the third state in which the console box 12 shown in FIG. 8 is in the flip-up position and the gate bar 42 is in the open position, and the operation of the work machine is locked (the state in which the handle 22 is in (C)). And can be switched.

以上に説明したように、本実施形態によれば、コンソールボックスのチルト角度を調節する操作は最初の１回で済み、操作が容易になるという効果が得られる。また、ゲート操作レバーの操作のみで乗降の操作が可能になり、乗降時のレバー操作が簡便になるという効果も得られる。   As described above, according to the present embodiment, the operation of adjusting the tilt angle of the console box is performed only once, and an effect that the operation becomes easy can be obtained. Moreover, the operation of getting on and off can be performed only by operating the gate operation lever, and the lever operation at the time of getting on and off can be simplified.
