Description

  The present invention relates to a manual storage unit structure in a driving unit of a turning work machine.

  Conventionally, since the swivel work machine is used outdoors, various parts and the like constituting the swivel work machine are likely to deteriorate. However, it is a big problem that the work is interrupted for a long time due to a failure caused by this. . Therefore, it is necessary to frequently inspect and replace parts, and a structure capable of easily performing these is desired.

  However, in general, a turning work machine cannot provide a sufficient space as a whole turning work machine in order to efficiently perform a desired work, etc. At present, it is difficult to add a new structure.

  As one of means for solving this, for example, as shown in Patent Document 1, a bonnet capable of inspecting the engine or the like is provided at the rear of the driver's seat of the turning work machine so as to be opened and closed. It is possible to easily check the engine and its peripheral parts.

  In addition, it is desirable that a manual that describes how to handle a swing work machine in a swing work machine can be confirmed as quickly as possible when it is desired to check the operation method and the inspection method. Therefore, it is desirable that the manual can be stored around the driver's seat, which is the driving section closest to the worker.

  However, as described above, the present situation is that the turning work machine cannot provide a space margin even in the operating part.

  As one of means for solving this problem, for example, as shown in Patent Document 2, there is a storage section for storing a manual on the back of the seat of the driver's seat. Is possible.

Japanese Patent No. 3294100 Japanese Patent No. 3425350

  However, in the above-described bonnet (Patent Document 1), for example, after performing an inspection operation or the like behind the turning work machine with the bonnet for engine inspection or the like, the operation unit is returned to the operation unit and the engine is started to start the turning work machine. There are cases where the result of inspection or adjustment is confirmed while performing the operation or the like, and if insufficient, the engine is stopped and the inspection or the like is performed again behind the turning work machine. In particular, when it becomes necessary to make repeated adjustments or the like, the bonnet portion is away from the operating section, so the reciprocation must be repeated frequently, which is not complicated and unintended.

  Furthermore, even if the bonnet is opened from the back of the turning work machine, all of the engine components cannot be placed behind the turning work machine. Therefore, the starter, alternator, etc. If parts are located below the engine room or placed in front of the engine room, it may be difficult to reach or reach the desired part, or it may be difficult to see in the dark. In addition, maintenance was poor, and even hands that touched parts that did not require inspection were touched.

  On the other hand, in the above-described manual storage unit (Patent Document 2), when the manual to be stored is not covered with a cover or the like, the manual is directly exposed to rain, dust, or the like, so that it is deteriorated and cannot be used.

  Also, even in the case where the stored manual is covered and locked with a cover or the like, the manual is taken out from the manual storage part on the back of the seat for the inspection of the engine, for example, and the rear of the turning work machine with the bonnet (Patent Document) Even after the inspection work in 1), the driver returns to the driving section again, and even if the manual is stored in the manual storage section on the back of the driver's seat, if it becomes necessary to make repeated adjustments, it becomes cumbersome and the cover is locked. Management deficiencies such as storing manuals without doing so tend to occur.

  This also has a side where it is difficult to visually recognize the presence or absence of locking because the manual storage portion is provided on the back of the seat of the driver's seat, and therefore forgetting to lock is likely to occur unless consciously checking. In such a case and in the case of a structure not covered with a cover or the like, it is a situation that a third party can take out the manual without permission.
