As this type of working machine, a vehicle body frame is provided with a machine room for accommodating various machines in addition to a driver's cab and various working machines (for example, working machines configured with booms, arms, buckets, etc.). Is known (for example, see Patent Document 1).

  In a work machine in which a machine room is provided in a body frame like the work machine described in Patent Document 1, generally, an opening facing the inside of the machine room is formed in a side surface portion of the body frame. Maintenance of various machines arranged inside the machine room is performed through the opening.

Japanese Patent Laid-Open No. 2006-102358

  By the way, in recent years, a hybrid specification working machine that uses a generator motor together with an engine as a drive source has been developed, and the number of various machines installed in the machine room tends to increase. Conventionally, there is a demand for downsizing work machines. Therefore, in recent work machines, the space between various machines and the body frame in the machine room is reduced.

  However, if the space is reduced in this way, sufficient space cannot be secured inside the machine room, and it will be difficult to perform maintenance on various machines such as replacement of the oil filter of the hydraulic pump. There was a problem.

  Further, as a method for improving maintainability, there is a method in which various machines to be maintained are installed in the vicinity of the opening of the machine room. However, in general, the open / close panel that covers the opening of the machine room is thinned in order to facilitate its movement, and the rigidity may not be sufficient.

  Therefore, when various machines to be maintained are installed near the opening, they are installed near the opening / closing panel when the opening / closing panel covering the opening is deformed or damaged due to contact with the surrounding environment. There was a risk of deformation and breakage in various machines.

  The present invention has been made in view of the above points, and it is possible to easily perform maintenance of various machines housed in the machine room and to prevent deformation and breakage of various machines. The purpose is to provide.

The work machine of the present invention is
A working machine including a vehicle body frame having an opening of a machine room provided on a side surface and an openable and closable panel covering the opening,
Inside the machine room, an aftertreatment device connected to the exhaust system of the engine, a gantry supporting the aftertreatment device, a reinforcing member movable from the inside to the outside of the machine room, A coupling mechanism for movably coupling the reinforcing member to the gantry,
The gantry has a pair of legs at a position facing the opening,
When the reinforcing member is accommodated in the machine room, the reinforcing member is bridged between the pair of legs.

  Thus, in the work machine of the present invention, the reinforcement member is configured to be movable toward the outside of the machine room (for example, turnable or pullable) by providing the coupling mechanism. As a result, when performing maintenance of various machines arranged inside the machine room, the reinforcing member can be retracted to the outside of the machine room, so that the space for maintenance can be easily kept inside the machine room. Can be secured.

  In addition, in the work machine according to the present invention, a member that is bridged to a pair of legs of the gantry at a position facing the opening when accommodated in the machine room (that is, both sides of the gantry The member whose part is supported is a reinforcing member. Therefore, the reinforcing member faces the gantry and the open / close panel when the open / close panel is closed. Here, since the gantry supports a heavy post-processing device among various machines installed in the machine room, the gantry is formed using a highly rigid material.

  As a result, even when the open / close panel collides with the surrounding environment, the open / close panel is supported by the highly rigid base via the reinforcing member, so that deformation and breakage are prevented. As a result, deformation and breakage of various machines housed in the machine room provided inside the open / close panel are also prevented.

  Further, in the work machine of the present invention, the pair of legs of the gantry is located at a position facing the opening, so that if the open / close panel collides with the surrounding environment, the reinforcing member Therefore, it is sandwiched between the opening / closing panel deformed inward and the pair of legs of the gantry.

  As a result, even if the open / close panel collides with the surrounding environment and the coupling mechanism is damaged, the position of the reinforcing member is held to some extent by the open / close panel and the pair of legs of the mount. Is done. As a result, even if the opening / closing panel subsequently collides with the surrounding environment, the various machines arranged in the machine room are protected by the reinforcing members as they are.

  Therefore, according to the working machine of the present invention, it is possible to prevent deformation and breakage of various machines arranged inside the machine room, and also to secure a sufficient space inside the machine room, Maintenance of various machines can be easily performed.

In the work machine of the present invention,
The machine disposed in the machine room has a protruding portion that protrudes toward the opening rather than the gantry,
The reinforcing member is located below the protruding portion when being accommodated in the machine room, and the various machines accommodated in the machine room have a protruding portion. There is something. Therefore, when various machines arranged in the vicinity of the reinforcing member have such a protruding portion, the reinforcing member is positioned below the protruding portion when the panel is closed. If comprised in this way, space saving of a machine room can be achieved, and by extension, the size of the whole work machine can be reduced. In addition, since the reinforcing member is positioned below, it is difficult for the reinforcing member to reach a state during maintenance, and the reinforcing member can be easily moved.

In the work machine of the present invention,
A plurality of various machines are arranged inside the machine room,
It is preferable that at least one of the plurality of various machines is attached to the inside of the machine room of the reinforcing member.

  With this configuration, the machine attached to the reinforcing member can be moved from the inside of the machine room where there is not enough space to perform the simple operation of moving the reinforcing member. Can be easily moved to the outside. Thereby, the maintenance of the machine can be performed easily.

Moreover, in the work machine of the present invention, in the case of a configuration in which the machine is attached to the reinforcing member,
The various machines include a first machine fixed inside the machine room, and a second machine attached to the inside of the machine room of the reinforcing member,
The first machine and the second machine are connected to each other by piping,
It is preferable that at least a part of the piping is routed so as to extend along the reinforcing member.

  If comprised in this way, since it will prevent that piping hangs down when a reinforcement member is opened, piping will become further difficult to prevent a maintenance operation | work. Thereby, maintenance can be performed more easily.

Moreover, in the work machine of the present invention, in the case of a configuration in which the machine is attached to the reinforcing member,
It is preferable that the machine attached to the reinforcing member is attached to the reinforcing member via a buffer member.

  In this way, if a shock absorbing member is provided between the reinforcing member and the machine attached thereto, even if the shock is transmitted to the reinforcing member, the shock is absorbed by the shock absorbing member. It is possible to prevent deformation and breakage of the installed machine.

FIG. 2A is a plan view schematically showing the inside of the machine room of the hydraulic excavator in FIG. 1, FIG. 2A shows a state in which the holding member is closed, and FIG. 2B shows a state in which the holding member is opened. The side view of the machine room of FIG. The perspective view which shows the structure of the oil filter of the hydraulic pump accommodated in the machine room of FIG.

  Hereinafter, a hydraulic excavator S that is a work machine according to an embodiment will be described with reference to the drawings. In the following description, the front and front sides in the traveling direction of the excavator S are simply referred to as “front” and “front”, and the rear and rear sides in the traveling direction are simply referred to as “rear” and “rear”.

  In this embodiment, a hydraulic excavator S is used as an example of a work machine. However, the work machine of the present invention includes an opening of a machine room and an open / close panel that covers the opening on a side surface of a vehicle body frame. There is no limitation to the hydraulic excavator. For example, a crane vehicle or the like may be used.

  As shown in FIG. 1, the hydraulic excavator S includes a lower traveling body 1 and an upper swinging body 2 (body frame) that is mounted on the lower traveling body 1 so as to be able to swivel.

  The lower traveling body 1 includes a lower frame 1a and a pair of crawlers 1b provided on both sides of the lower frame 1a. The crawler 1b is driven by a traveling hydraulic motor that is a hydraulic actuator.

  Note that the lower traveling body is not limited to the one constituted by the lower frame and the crawler, and may be any one provided with a vehicle body frame provided with a machine room. Therefore, the lower traveling body may be moved by wheels or may be a legged movement. Further, when the work machine is used on water, the lower traveling body may be a trolley or the like.

  The upper swing body 2 is provided on an upper frame 2a that is supported to be rotatable with respect to the lower frame 1a, a cab 2b that is provided on the front side of the upper frame 2a, and a side of the cab 2b. The work machine 2c includes a cab 2b and a counterweight 2d mounted behind the work machine 2c, and a machine room 2e defined by the upper frame 2a and the counterweight 2d.

  In the cab 2b, the driver operates the hydraulic excavator S, such as various levers (not shown) for operating the work implement 2c, turning the upper swing body 2, and moving the lower traveling body 1. Various devices are provided.

  The work implement 2c is pivotally connected to the upper frame 2a of the upper swing body 2 so as to be pivotable, an arm 2c2 pivotally coupled to the boom 2c1, and the arm 2c2. Bucket 2c3.

  Further, the work implement 2c includes a boom cylinder 2c4 having both ends attached to the upper frame 2a and the boom 2c1 of the upper swing body 2, an arm cylinder 2c5 having both ends attached to the boom 2c1 and the arm 2c2, an arm 2c2, A bucket cylinder 2c6 having both ends attached to the bucket 2c3 is provided.

  The boom 2c1 is pivotally supported by the upper frame 2a of the upper swing body 2 so as to be pivotable, and pivots by the expansion and contraction operation of the boom cylinder 2c4 with the shaft as a fulcrum. The arm 2c2 is pivotally supported by the boom 2c1, and is rotated by the expansion / contraction operation of the arm cylinder 2c5 with the shaft as a fulcrum. The bucket 2c3 is pivotally supported by the arm 2c2, and rotates by the expansion and contraction operation of the bucket cylinder 2c6 with the shaft as a fulcrum.

  The counterweight 2d maintains a balance as a whole of the excavator S with the work machine 2c by its weight. A space serving as a machine room 2e is formed between the counterweight 2d, the cab 2b, and the work machine 2c.

  As shown in FIG. 2, the inside and the outside of the machine room 2 e are communicated with each other through an opening 2 e 1 provided on the side surface of the upper swing body 2. Maintenance of various machines accommodated in the machine room 2e is performed through the opening 2e1. The opening 2e1 is covered with an openable / closable opening / closing panel 2f.

  As shown in FIGS. 2 and 3, the machine room 2e includes an engine 3 and a generator motor 4 as a drive source, a hydraulic pump 5 (first machine) for supplying oil to the engine 3 and the like, exhaust of the engine. Along with various machines such as the post-processing device 6 connected to the system, a support structure for supporting them (for example, a stand 7 for supporting the post-processing device 6) is installed.

  In the vicinity of the hydraulic pump 5, a first oil filter 8a (second machine) and a second oil filter 8b (second machine) for removing abrasion powder and the like from oil supplied to the engine 3 and the like are installed. Yes. The engine 3, the hydraulic pump 5, and the first oil filter 8a and the second oil filter 8b are connected by a pipe 8c.

  As shown in FIG. 4, the 1st oil filter 8a is comprised by the connection part 8a1 for attaching to the reinforcement member 9 mentioned later, and the main-body part 8a2 comprised as a cartridge with respect to the connection part 8a1.

  The connecting portion 8a1 is provided with a plurality of mouth portions 8a3 communicating with the inside of the main body portion 8a2. Piping 8c is attached to these mouth parts 8a3. The first oil filter 8a and the engine 3 or the second oil filter 8b are connected to each other via the pipe 8c.

  The main body 8a2 houses a filter element therein. Therefore, the oil supplied from the engine 3 to the main body portion 8a2 through the predetermined mouth portion 8a3 is filtered by the filter element, then discharged from the other mouth portion 8a3, and supplied to the second oil filter 8b. .

  The second oil filter 8b is configured in the same manner as the first oil filter 8a. The second oil filter 8b is disposed between the first oil filter 8a and the hydraulic pump 5, and after further filtering the oil supplied from the first oil filter 8a, supplies the oil to the hydraulic pump 5.

  Two oil filters are not necessarily provided, and only one oil filter may be provided, or three or more oil filters may be provided.

  Returning to FIG. 2 and FIG. 3, the post-processing device 6 includes, for example, a urea SCR (selective catalytic reduction) unit that removes nitrogen oxides (NOx) and the like contained in exhaust gas generated from a diesel engine.

  Since the aftertreatment device 6 is for treating the exhaust gas from the engine 3, it is installed in the vicinity of the engine 3 together with the hydraulic pump 5 that supplies oil to the engine 3. Specifically, the post-processing device 6 and the hydraulic pump 5 are installed at the upper and lower portions of the gantry 7 fixed at positions adjacent to the engine 3 and the generator motor 4.

  The gantry 7 is disposed at a position facing the opening 2e1 of the machine room 2e (specifically, a position exposed from the opening 2e1 or close to a portion forming the opening 2e1 of the upper swing body 2). ing.

  The gantry 7 includes a top plate 7a on which the post-processing device 6 is placed and a plurality of legs 7b that support the top plate 7a horizontally. The post-processing device 6 is fixed to the top plate 7a with a bolt or the like via a vibration isolating member (not shown) such as a mount rubber. Each leg 7b is fixed to the upper frame 2a with bolts or the like.

  The post-processing device 6 generally has a weight of about 100 kg when the excavator S is of the 20t class. In order to support the post-processing device 6 having such a large weight, the gantry 7 that supports the post-processing device 6 is formed of a material having high rigidity.

  By the way, the hydraulic excavator S is a hybrid type model that employs not only the engine 3 but also the generator motor 4 as a drive source. Therefore, the space inside the machine room 2e is narrower than that of a hydraulic excavator using only the engine as a drive source by the amount of the generator motor 4 (see FIG. 2).

  When the space inside the machine room 2e is narrow, the members surrounding the machine room 2e (specifically, the upper frame 2a, the counterweight 2d, the opening / closing panel 2f covering the opening 2e1, etc.) are deformed by collision with the surrounding environment, etc. When this occurs, the deformed member and the various machines accommodated in the machine room 2e are likely to come into contact with each other. As a result, various machines may be deformed or damaged.

  In particular, the open / close panel 2f is designed to be lightweight in order to facilitate its open / close operation (that is, unlike the upper frame 2a and the counterweight 2d, since it is thinned, etc., its rigidity is low). ), Easily deformed. Therefore, there is a higher possibility that the opening / closing panel 2f and the machine located at the position facing the opening / closing panel 2f will be contacted and deformed / damaged based thereon.

  Therefore, in the hydraulic excavator S, the reinforcing member 9 that supports and reinforces the opening / closing panel 2f from the machine room 2e side causes deformation of the opening / closing panel 2f, and hence deformation and breakage of various machines due to contact with the deformed opening / closing panel 2f. It is preventing.

  The reinforcing member 9 is a long plate-like bridge that is bridged to a pair of leg portions 7b arranged at a position facing the opening 2e1 of the machine room 2e among the plurality of leg portions 7b of the gantry 7. It is a member. The reinforcing member 9 is located at a position facing the open / close panel 2f when housed in the machine room 2e.

  Here, the reinforcing member 9 to which the first oil filter 8a and the second oil filter 8b are attached is configured to face the gantry 7 and the open / close panel 2f when the open / close panel 2f is closed. Yes. Further, since the gantry 7 to which the reinforcing member 9 is attached supports the post-processing device 6 having a large weight among various machines installed in the machine room 2e, a material having high rigidity is used. Is formed.

  As a result, even when the open / close panel 2f has collided with the surrounding environment, the open / close panel 2f is supported by the rigid base 7 via the reinforcing member 9, so that the deformation / breakage is prevented. Is prevented. As a result, various machines (in particular, the first oil filter 8a and the second oil filter 8b attached to the reinforcing member 9) housed in the machine room 2e provided inside the open / close panel 2f. Deformation and breakage are also prevented.

  Further, in the hydraulic excavator S, the pair of legs 7b of the gantry 7 is located at the position facing the opening 2e1 of the machine room 2e, so that if the open / close panel 2f collides with the surrounding environment, The reinforcing member 9 is sandwiched between the opening / closing panel 2f deformed inward by the collision and the pair of legs 7b of the gantry 7.

  As a result, if the open / close panel 2f collides with the surrounding environment, the connecting portion (specifically, a hinge 9a (connecting mechanism) described later) between the reinforcing member 9 and the gantry 7 is damaged. Even if it exists, the position of the reinforcing member 9 is held to some extent by the open / close panel 2f and the pair of legs 7b of the gantry 7. As a result, even if the open / close panel 2f subsequently collides with the surrounding environment, the various machines arranged inside the machine room 2e are protected by the reinforcing member 9 as they are.

  Meanwhile, if the space inside the machine room 2e is narrowed, a sufficient space for maintenance inside the machine room 2e cannot be secured, and maintenance work for various machines housed in the machine room 2e is not possible. Is difficult to do. In particular, it is difficult to replace the first oil filter 8a and the second oil filter 8b connected to the hydraulic pump 5 for supplying oil to the engine 3 and the like.

  In order to prevent the surroundings from being contaminated by oil leaked during the replacement work, an oil pan is placed below the first oil filter 8a and the second oil filter 8b prior to the replacement. This is because it needs to be installed.

  That is, for the replacement work of the first oil filter 8a and the second oil filter 8b, it is not enough to simply move the first oil filter 8a and the second oil filter 8b. This is because a certain amount of space is required.

  Therefore, in the hydraulic excavator S, the reinforcing member 9 is configured to be movable from the inside of the machine room 2e to the outside, and by holding the first oil filter 8a and the second oil filter 8b in the reinforcing member 9, The first oil filter 8a and the second oil filter 8b can be easily replaced.

  As shown in FIG. 3, in the machine room 2e, the gantry 7 is arranged so that the pair of leg portions 7b faces the opening 2e1. Between the pair of leg portions 7b, the hydraulic pump 5 is disposed at a position facing the opening 2e1.

  A hinge 9 a (a coupling mechanism) is provided at one end of the reinforcing member 9. The reinforcing member 9 is rotatably attached to one of the pair of leg portions 7b (the leg portion 7b positioned below in FIG. 2) via the hinge 9a.

  Further, a hooking claw (not shown) is provided at the other end of the reinforcing member 9. By this nail | claw, the reinforcement member 9 can be hooked with respect to the other (leg part 7b located upwards in FIG. 2) of a pair of leg part 7b. In addition, when it is the structure where the reinforcement member 9 is fixed by other means, such as a magnet, you may abbreviate | omit the nail | claw for latching.

  The first oil filter 8a and the second oil filter 8b are fixed to the hydraulic pump 5 side of the reinforcing member 9 thus configured (that is, inside the machine chamber 2e) via a bracket 9b described later. ing.

  Thereby, in the hydraulic excavator S, the first oil filter 8a and the second oil filter 8b can be moved only by performing a simple operation of rotating the reinforcing member 9 (transitioning from the state of FIG. 2A to the state of FIG. 2B). The open / close panel 2f and the reinforcing member 9 can be easily moved integrally from the inside of the machine room 2e where there is not enough space to the outside of the machine room 2e where there is enough space. Yes.

  Moreover, since the reinforcing member 9 and the hydraulic pump 5 are located at positions facing each other, the pipe 8c for connecting them does not become excessively long. The pipe 8c is a portion located in the vicinity of the reinforcing member 9, and is hooked and routed on the hydraulic pump 5 side of the reinforcing member 9 by a hook member (not shown).

  This prevents the pipe from drooping when the reinforcing member 9 is opened. Therefore, when the first oil filter 8a and the second oil filter 8b are exchanged, the work may be hindered by the pipe 8c. Absent. When the pipe 8c is sufficiently short, the pipe 8c does not necessarily have to be routed along the reinforcing member 9 in the reinforcing member 9.

  Further, in the hydraulic excavator S, only a part of the pipe 8c is routed along the reinforcing member 9, but the site where the pipe 8c is routed may be appropriately changed according to the structure of the work machine. For example, not only a part but the whole may be routed along the reinforcing member 9.

  By the way, in the hydraulic excavator S, the reinforcing member 9 is used together with the gantry 7 to which the reinforcing member 9 is attached in order to suppress deformation / breakage of the open / close panel 2f.

  Therefore, when an impact is applied to the reinforcing member 9, the impact cannot be sufficiently transmitted to the gantry 7, and the first oil filter 8a and the second oil filter 8b attached to the reinforcing member 9 are also impacted. May be added. Such an impact causes deformation and breakage of the first oil filter 8a and the second oil filter 8b.

  Therefore, in the excavator S, the first oil filter 8a and the second oil filter 8b are attached to the reinforcing member 9 via the bracket 9b (buffer member). Thereby, even if an impact is transmitted to the reinforcing member 9, the impact is absorbed by the bracket 9b, so that the deformation and breakage of the first oil filter 8a and the second oil filter 8b are prevented.

  In addition, when the reinforcing member 9 is provided at a position where it is difficult to transmit an impact from the outside, the bracket 9b as a buffer member may be omitted. Further, the buffer member is not limited to the bracket, and may be any member that can absorb the impact. For example, it may be composed of an elastic member such as rubber.

  The reinforcing member 9 is bridged to the pair of legs 7b of the gantry 7, and the hydraulic pump 5 is disposed between the pair of legs 7b. Therefore, when the reinforcing member 9 is closed, the maintenance of the hydraulic pump 5 may be deteriorated by being blocked by the reinforcing member 9.

  Therefore, in the hydraulic excavator S, by configuring the reinforcing member 9 using a horizontally long member, by providing a gap above and below the reinforcing member 9, even if the reinforcing member 9 remains closed, The hydraulic pump 5 can be maintained.

  In addition, the reinforcing member 9 should just be a shape which can be attached to the mount frame 7, and does not necessarily need to be a horizontally long member.

  For example, when the opening is provided in addition to the opening 2e1 other than the side surface (for example, the lower surface or the upper surface) of the upper swing body 2, the hydraulic pump 5 can be maintained from other directions. In this case, a plate material that covers the entire opening 2e1 side of the hydraulic pump 5 may be used. With such a configuration, the hydraulic pump 5 can be protected by the holding member when an impact is applied to the panel covering the opening 2e1.

  In addition, when the reinforcing member 9 is provided, the space inside the machine room 2e is reduced by the amount of the reinforcing member 9 disposed. Therefore, in the hydraulic excavator S, the semicircular cutout portion 9c provided in the substantially central upper portion (upper edge) of the reinforcing member 9 is provided, and when the open / close panel 2f is closed, the cutout portion 9c is provided inside the cutout portion 9c. The protruding portion 5a of the hydraulic pump 5 (the portion corresponding to the axis of the rotating body inside the hydraulic pump 5) is positioned. That is, the reinforcing member 9 is configured to be positioned below the protruding portion.

  Thereby, the increase in the required space inside the machine room 2e due to the provision of the reinforcing member 9 is suppressed, and consequently, the enlargement of the entire hydraulic excavator S is suppressed.

  In addition, you may design the shape of the notch part 9c suitably according to the shape of the reinforcement member 9 itself and the shape of the protrusion part 5a. Therefore, when the vertical width of the reinforcing member 9 is sufficiently short, the notch 9c may be reduced or omitted.

  Although the illustrated embodiment has been described above, the present invention is not limited to such a form.

  For example, in the above embodiment, the first machine fixed inside the machine room 2e is the hydraulic pump 5, and the second machine attached to the reinforcing member 9 is the first oil filter 8a and the second oil. The filter 8b is used. However, the machine attached to the reinforcing member of the present invention is not limited to such a machine.

  For example, the first machine may be an engine and the second machine may be a fuel filter for the engine. In addition, the machine attached to the reinforcing member is not limited to filters and the like, but may be an independent machine that is used alone.

  Moreover, in the said embodiment, the reinforcement member 9 is rotatably attached with respect to the mount frame 7 with the hinge 9a which is a connection mechanism. However, the coupling mechanism of the present invention is not limited to such a configuration, and any coupling member may be used as long as the reinforcing member can be attached to the gantry so as to be movable toward the outside of the machine room. For example, it may be freely drawable with respect to the gantry.
