　次に、本実施形態に係る油圧ショベル１のメンテナンス方法について説明する。図９及び図１０は、本実施形態に係る油圧ショベル１がメンテナンスされるときの上部旋回体２０の一例を示す斜視図である。なお、図面を見やすくするために、図１０は、エンジン５１が除かれた状態を示す。油圧ショベル１のメンテナンスは、油圧ショベル１の点検を含む。 Next, a maintenance method for the excavator 1 according to this embodiment will be described. 9 and 10 are perspective views showing an example of the upper swing body 20 when the excavator 1 according to the present embodiment is maintained. In order to make the drawing easier to see, FIG. 10 shows a state where the engine 51 is removed. Maintenance of the excavator 1 includes inspection of the excavator 1.
　例えば、エンジン５１の少なくとも一部をメンテナンスする場合、図９に示すように、プレート部材９０が区画部材８１に支持された状態で、プレート部材９０から遮蔽部材９２が外される。遮蔽部材９２は、固定部材９３によりプレート部材９０に着脱可能に支持される。そのため、固定部材９３による固定を解除するだけで、遮蔽部材９２はプレート部材９０から外される。遮蔽部材９２が外されることにより、プレート部材９０に開口部９０Ｋが形成される。作業者は、エンジン室５０の外側から、開口部９０Ｋを介して、エンジン５１を点検することができる。 For example, when maintaining at least a part of the engine 51, the shielding member 92 is removed from the plate member 90 in a state where the plate member 90 is supported by the partition member 81 as shown in FIG. The shielding member 92 is detachably supported by the plate member 90 by a fixing member 93. Therefore, the shielding member 92 is removed from the plate member 90 only by releasing the fixing by the fixing member 93. By removing the shielding member 92, an opening 90K is formed in the plate member 90. An operator can check the engine 51 from the outside of the engine chamber 50 through the opening 90K.
　例えば、熱交換器室６０の熱交換器の少なくとも一部をメンテナンスする場合、図１０に示すように、区画部材８１及び上カバー部材８３からプレート部材９０が外される。プレート部材９０は、固定部材９１により区画部材８１及び上カバー部材８３に着脱可能に支持される。そのため、固定部材９１による固定を解除するだけで、プレート部材９０は区画部材８１及び上カバー部材８３から外される。 For example, when maintaining at least a part of the heat exchanger in the heat exchanger chamber 60, the plate member 90 is removed from the partition member 81 and the upper cover member 83 as shown in FIG. The plate member 90 is detachably supported by the partition member 81 and the upper cover member 83 by the fixing member 91. Therefore, the plate member 90 is removed from the partition member 81 and the upper cover member 83 simply by releasing the fixing by the fixing member 91.
　本実施形態においては、プレート部材９０を外すとき、フロア部材２６が前方にチルトされる。図８に示したように、フロア部材２６は、プレート部材９０よりも前方にチルト可能である。そのため、作業者は、フロア部材２６を前方にチルトさせた状態で、固定部材９１の解除作業を円滑に実施することができる。固定部材９１による固定が解除された後、プレート部材９０は、左方に引き出され、アングル部材９４から外される。本実施形態においては、フロア部材２６がプレート部材９０よりも前方にチルトするので、作業者は、プレート部材９０を引き出す作業を円滑に実施することができる。 In the present embodiment, when the plate member 90 is removed, the floor member 26 is tilted forward. As shown in FIG. 8, the floor member 26 can tilt forward from the plate member 90. Therefore, the operator can smoothly perform the releasing operation of the fixing member 91 in a state where the floor member 26 is tilted forward. After the fixing by the fixing member 91 is released, the plate member 90 is pulled out to the left and removed from the angle member 94. In the present embodiment, the floor member 26 tilts forward relative to the plate member 90, so that the operator can smoothly carry out the operation of pulling out the plate member 90.
　プレート部材９０が外されることにより、図１０に示すように、プレート部材９０が存在していた位置に開口部２００が形成される。 By removing the plate member 90, an opening 200 is formed at the position where the plate member 90 was present, as shown in FIG.
　ファンガード１１０の少なくとも一部は、プレート部材９０と対向するように配置される。そのため、プレート部材９０が外されることにより、開口部２００の近くにファンガード１１０の少なくとも一部が存在することとなる。したがって、作業者は、開口部２００を介して、ファンガード１１０についての作業を円滑に実施することができる。 At least a part of the fan guard 110 is disposed so as to face the plate member 90. Therefore, when the plate member 90 is removed, at least a part of the fan guard 110 exists near the opening 200. Therefore, the worker can smoothly perform the work on the fan guard 110 through the opening 200.
　熱交換器室６０の熱交換器の少なくとも一部をメンテナンスする場合、ファンガード１００がシュラウド部材１２０から外される。ファンガード１１０は、固定部材１１５によりシュラウド部材１２０に着脱可能に支持される。そのため、固定部材１１５による固定を解除するだけで、ファンガード１１０はシュラウド部材１２０から外される。 When maintaining at least part of the heat exchanger in the heat exchanger chamber 60, the fan guard 100 is removed from the shroud member 120. The fan guard 110 is detachably supported by the shroud member 120 by a fixing member 115. Therefore, the fan guard 110 is removed from the shroud member 120 only by releasing the fixing by the fixing member 115.
　固定部材１１５は、前後方向においてプレート部材９０と同じ位置に設けられる。そのため、プレート部材９０が外されることにより、開口部２００の近くに固定部材１１５が存在することとなる。したがって、作業者は、開口部２００を介して、固定部材１１５の固定を解除するための作業を円滑に実施することができる。 The fixing member 115 is provided at the same position as the plate member 90 in the front-rear direction. Therefore, when the plate member 90 is removed, the fixing member 115 exists near the opening 200. Therefore, the operator can smoothly perform an operation for releasing the fixing of the fixing member 115 through the opening 200.
　固定部材１１５による固定が解除された後、シュラウド部材１２０から外されたファンガード１１０がエンジン室５０から搬出される。本実施形態において、車幅方向及び上下方向のそれぞれにおいて、プレート部材９０の寸法は、ファンガード１１０の寸法よりも大きい。したがって、プレート部材９０が外れたことにより形成された開口部２００の車幅方向及び上下方向の寸法も、プレート部材９０よりも大きい。したがって、作業者は、開口部２００を介して、ファンガード１１０をエンジン室５０から円滑に搬出することができる。 After the fixing by the fixing member 115 is released, the fan guard 110 removed from the shroud member 120 is carried out from the engine compartment 50. In the present embodiment, the dimension of the plate member 90 is larger than the dimension of the fan guard 110 in each of the vehicle width direction and the vertical direction. Therefore, the dimension in the vehicle width direction and the vertical direction of the opening 200 formed by the removal of the plate member 90 is also larger than that of the plate member 90. Therefore, the operator can smoothly carry out the fan guard 110 from the engine compartment 50 through the opening 200.
　以上説明したように、本実施形態によれば、ファンガード１１０の少なくとも一部が、プレート部材９０と対向するように配置される。そのため、固定部材９１による固定が解除され、プレート部材９０が外されて開口部２００が形成されることにより、作業者は、開口部２００を介して、ファンガード１１０を円滑に取り外しすることができる。 As described above, according to the present embodiment, at least a part of the fan guard 110 is disposed so as to face the plate member 90. Therefore, the fixing by the fixing member 91 is released, the plate member 90 is removed, and the opening 200 is formed, so that the operator can smoothly remove the fan guard 110 through the opening 200. .
　また、本実施形態においては、ファンガード１１０は、固定部材１１５によりシュラウド部材１２０に着脱可能に支持される。これにより、固定部材１１５による固定が解除されるだけで、ファンガード１１０を簡単に外すことができる。また、固定部材１１５は、前後方向においてプレート部材９０と同じ位置に設けられるので、プレート部材９０が外されて開口部２００が形成されることにより、作業者は、開口部２００を介して、固定部材１１５の固定を解除する作業を円滑に実施することができる。また、プレート部材９０に近い固定部材１１５のみをボルトにしておき、プレート部材９０から遠い固定部材１１５をスライド式にしておけば、プレート部材９０に近い固定部材１１５を外すだけでファンガード１１０をさらに簡単に外すことができる。 In the present embodiment, the fan guard 110 is detachably supported by the shroud member 120 by the fixing member 115. Thereby, the fan guard 110 can be easily removed simply by releasing the fixing by the fixing member 115. Since the fixing member 115 is provided at the same position as the plate member 90 in the front-rear direction, the plate member 90 is removed and the opening 200 is formed, so that the operator can fix through the opening 200. The operation of releasing the fixation of the member 115 can be performed smoothly. Further, if only the fixing member 115 close to the plate member 90 is a bolt and the fixing member 115 far from the plate member 90 is made a slide type, the fan guard 110 can be further removed simply by removing the fixing member 115 close to the plate member 90. Easy to remove.
　また、本実施形態によれば、フロア部材２６は、プレート部材９０よりも前方にチルト可能である。そのため、プレート部材９０を区画部材８１から外す場合、作業者は、固定部材９１による固定を解除する作業及びプレート部材９０を引き出す作業を円滑に実施することができる。 Further, according to the present embodiment, the floor member 26 can tilt forward from the plate member 90. Therefore, when removing the plate member 90 from the partition member 81, the operator can smoothly perform the operation of releasing the fixation by the fixing member 91 and the operation of pulling out the plate member 90.
　また、本実施形態によれば、プレート部材９０の少なくとも一部は、後方に向かって上方に傾斜するように配置される。これにより、空間ＳＰにおけるブーム１１の移動が妨げられない。また、プレート部材９０の少なくとも一部が後方に向かって上方に傾斜し、ファンガード１１０の少なくとも一部がプレート部材９０とファン１００との間においてファン１００よりも前方且つ上方に配置されるので、プレート部材９０が外されたとき、ファンガード１１０は開口部２００の近くに配置される。これにより、作業者は、ファンガード１１０に容易にアクセスすることができる。 Further, according to the present embodiment, at least a part of the plate member 90 is disposed so as to incline upward toward the rear. Thereby, the movement of the boom 11 in the space SP is not hindered. Further, since at least a part of the plate member 90 is inclined upward and rearward, at least a part of the fan guard 110 is disposed between the plate member 90 and the fan 100 in front and above the fan 100, When the plate member 90 is removed, the fan guard 110 is disposed near the opening 200. Thereby, the worker can easily access the fan guard 110.
　また、本実施形態においては、車幅方向及び上下方向のそれぞれにおいて、プレート部材９０の寸法は、ファンガード１１０の寸法よりも大きい。したがって、プレート部材９０を外すことによって形成される開口部２００の寸法も、ファンガード１１０の寸法よりも大きいこととなる。そのため、作業者は、開口部２００を介してファンガード１１０をエンジン室５０の外側に搬出する作業を円滑に実施することができる。 In this embodiment, the dimension of the plate member 90 is larger than the dimension of the fan guard 110 in each of the vehicle width direction and the vertical direction. Therefore, the dimension of the opening 200 formed by removing the plate member 90 is also larger than the dimension of the fan guard 110. Therefore, the worker can smoothly carry out the work of carrying out the fan guard 110 to the outside of the engine room 50 through the opening 200.
　また、本実施形態においては、プレート部材９０には、点検窓として機能する開口部９０Ｋが設けられる。これにより、プレート部材９０全体を外す必要が無い簡易なメンテナンス作業においては、開口部９０Ｋを介してメンテナンス作業を実施することができる。簡易なメンテナンス作業においては、フロア部材２６をチルトさせることなく、遮蔽部材９２を外すだけでよいので、煩雑な作業を実施しなくて済む。また、メンテナンス作業を実施しないときにおいては、開口部９０Ｋは遮蔽部材９２により遮蔽される。これにより、エンジン室５０は保護される。また、遮蔽部材９２は、固定部材９３によりプレート部材９０に着脱可能に支持される。これにより、固定部材９３による固定が解除されるだけで、遮蔽部材９２を簡単に外すことができる。 Further, in the present embodiment, the plate member 90 is provided with an opening 90K that functions as an inspection window. Thereby, in the simple maintenance work which does not need to remove the plate member 90 whole, a maintenance work can be implemented through the opening part 90K. In simple maintenance work, it is only necessary to remove the shielding member 92 without tilting the floor member 26, so that complicated work is not required. When the maintenance operation is not performed, the opening 90K is shielded by the shielding member 92. Thereby, the engine compartment 50 is protected.
