First, the locking device 114 of the moving mechanism 110 shown in FIG. 10A is released, and the battery 46 is moved to the side of the vehicle together with the front moving member 113. At this time, the tip moving member 113 is supported by the intermediate moving member 112 and starts to slide relative to the intermediate moving member 112. When the holding portion 113b comes into contact with the engaged portion 112b, the tip moving member 113 is moved forward. The sliding movement of the part moving member 113 is completed. Subsequently, when the battery 46 is moved to the side of the vehicle together with the tip moving member 113, the sliding movement of the intermediate moving member 112 with respect to the fixed member 111 is started. The sliding movement between the leading part moving member 113 and the intermediate moving member 112 is completed when the engaged part 112b is engaged with the engaging part 111b, and the movement of the battery 46 to the maintenance position is completed (see FIG. 11). ).

The tip moving member 113 is cantilevered with respect to the intermediate moving member 112 because the bottom surface thereof is in contact with the lower surface of the slide portion 112a of the intermediate moving member 112 and the holding portion 113b is in contact with the upper surface of the slide portion 112a. The intermediate moving member 112 is in contact with the fixing member 111 because the bottom surface thereof is in contact with the lower surface of the sliding portion 111a of the fixing member 111 and the upper surface including the engaged portion 112b is in contact with the upper surface of the sliding portion 111a. Cantilevered.
Thus, the battery 46 is held at the maintenance position on the side of the garbage collection vehicle 1, and the maintenance work can be performed without the battery 46 disposed in the box lower space Sd being obstructed by the dust container 2. Furthermore, since the maintenance position is set above the ground and the battery 46 is supported at the maintenance position, the lower surface of the battery 46 is obstructed by the vehicle engine and other mounted devices around the engine at the storage position. Although the work is hindered, the maintenance work can be performed at the maintenance position without being obstructed by the engine of the vehicle and other mounted devices around the engine. At this time, a hole for maintenance is provided on the bottom surface of the tip moving member 113, or the tip moving member 113 is configured by two channel members having a substantially U-shaped cross section like the intermediate moving member 112. Thus, the maintenance work on the lower surface of the battery 46 is further facilitated at the maintenance position.
After the maintenance work is completed, the battery 46 at the maintenance position is slid and returned to the travelable state shown in FIG.

  According to the refuse collection vehicle 1 of the present embodiment configured as described above, the battery 46 is supported by the moving member 111 so as to be movable to the side of the dust collection vehicle 1, and thus is disposed in the box lower space Sd. When performing maintenance work on the battery 46, the battery 46 is tilted to the side of the dust container 2 so that the maintenance work can be easily performed without being obstructed by the dust container 2. Therefore, the maintenance work of the driving device 58 arranged in the box lower space Sd can be easily performed. In particular, this is effective when inspecting and replacing the heavy battery 46.

  As shown in FIGS. 8 and 9, the moving mechanism 110 (in the example shown, the upper part of the fixing member 111) may be provided with a central support portion 64 ′. In this case, the dedicated central support portion 64 is provided. Can be dispensed with at low cost.

FIGS. 15-18 is a figure which shows the refuse collection vehicle by the 2nd Embodiment of this invention.
The second embodiment is mainly different from the first embodiment in that a cover for protecting the driving device and the hydraulic piping arranged in the space under the box is provided.
Hereinafter, the second embodiment will be described in detail. In this embodiment, the same configuration as that of the first embodiment is indicated by the same reference numeral as that of the first embodiment.
15 and 17, a pair of left and right side covers 100 are provided between the vehicle body frame 1b and the refuse storage box 2 so as to cover the driving devices 58 disposed in the box lower space Sd from both outer sides in the vehicle width direction.

Is attached. A locking device 105 that prevents the lower portion of the front cover portion 101 (vertical surface 101a) from rotating is attached to the fixing member 111 of the moving mechanism 110. Since the front cover 101 has a horizontal surface 101d fixed to the bottom plate 2b by welding, it is not necessary to form a bolt hole in the bottom plate 2b. For this reason, it can prevent that the sewage of the dust accommodated in the dust storage box 2 leaks outside from the bottom plate 2b.
The front cover 101 and the rib 103 can be fixed by welding. In this case, since there is no projecting part such as a bolt on the outer side of the front cover part 101, aesthetics can be improved.
Since the rear cover portion 102 has the same mounting structure as the front cover portion 101, detailed description thereof is omitted.

  In FIG. 15, the front cover portion 101 on the port side is a substantially central portion in the front-rear direction of the space formed between the bottom plate 2 b of the dust container 2 and the upper surface of the vehicle body frame 1 b when viewed from the side of the vehicle (the central support in FIG. It is arranged so as to cover the front part (including the box lower space Sd) and the lower part of the box front space Sf from the vicinity of the front surface of the portion 64. Thereby, the battery 46 arranged in the box lower space S and the power unit 49 arranged on the port side below the box front space Sf are covered and protected by the front cover portion 101 from the outer side on the port side. (See also FIG. 1). An opening 101 b is formed on the vertical surface 101 a of the front cover 101 so that the power cable 51 can be connected to the connector 52 of the charger 50. The opening 101b is opened and closed by a lid member (not shown).

  The port side rear cover portion 102 is disposed so as to cover a rear portion from the substantially central portion of the space formed between the bottom plate 2b and the upper surface of the vehicle body frame 1b in a side view of the vehicle. Specifically, the front end edge 102a of the rear cover portion 102 is disposed adjacent to the rear end edge 101c of the front cover portion 101, and the rear end edge 102b is adjacent to the front surface 2g1 of the stiffener 2g. Has been placed. Thereby, the space formed between the charger 50 and the valve block 33 disposed in the box lower space S, and the central support portion 64 and the rear support portion 65 of the support member 61 is formed by the rear cover portion 102. It is covered and protected from the outside on the port side (see also FIG. 1). Further, the lower surface of the rear cover portion 102 is formed in an arc shape along the rear wheel on the left side.

  In FIG. 17, the starboard side front cover portion 101 is a front portion (a space under the box) from the substantially central portion of the space formed between the bottom plate 2b of the dust container 2 and the upper surface of the vehicle body frame 1b in a side view of the vehicle. (Including Sd). Thereby, the battery 46 and the charger 50 arranged in the box lower space S are covered and protected from the outer side on the starboard side by the front cover portion 101 (see also FIG. 4). Note that the front end of the front cover portion 101 (the right side in FIG. 17) is arranged behind the box front space Sf to avoid interference with the step 96 arranged in the box front space Sf.

  The starboard-side rear cover portion 102 has the same arrangement and shape as the port-side rear cover portion 102. As a result, the space formed between the charger 50 and the valve block 33 disposed in the box lower space Sd and the central support portion 64 and the rear support portion 65 of the support member 61 is starboard by the rear cover portion 102. It is covered and protected from the outside of the side (see also FIG. 4).

  In the lower box space Sd, a valve block 33 containing a valve body is arranged in a state of being fixed to the upper surface of the base frame 72a of the lower box mounting part 72. The valve block 33 is connected to a hydraulic pipe 40 that is a pipe for supplying and discharging hydraulic oil (working fluid). The pipe sections 40a and 40b of the hydraulic pipe 40 are the same as those in the first embodiment. Similarly, it arrange | positions along each corner | angular part 2e and 2h of the refuse storage box 2. FIG.

  The entire pipe part 40a extending in the horizontal direction of the hydraulic pipe 40 is covered and protected from the outside in the vehicle width direction by the rear cover part 102 on the starboard side. Further, the piping part 40b extending diagonally forward in front of the hydraulic pipe 40 and the piping part 40c arranged in the horizontal direction along the upper surface of the dust container 2 are entirely on the side wall 2f side of the dust container 2. The upper cover portion 111 is covered and protected from the outside in the vehicle width direction. The rear cover portion 102 and the upper cover portion 111 constitute a cover member 110 that covers the hydraulic pipe 40 from the outside.

In FIG. 18, the upper cover portion 111 has an L-shaped cross section, and is parallel to a parallel portion 111a disposed substantially parallel to the side wall 2f of the dust container 2, and bent perpendicular to the parallel portion 111a. The vertical portion 111b is integrally formed.
The end of the parallel part 111a is sandwiched between an outer surface of a stiffener 2g formed in a U-shaped cross section and a sandwiching piece 112 having a substantially inverted Z-shaped section fixed along the outer surface. Further, the end portion of the vertical portion 111b is fixed to a fixing piece 113 made of a plurality of angle members fixed to the side wall 2f in contact with the side wall 2f by bolts 114 and nuts 115. Thereby, the piping part 40b is protected by covering the four sides with the side wall 2f, the stiffener 2g, and the upper cover part 111.

  Next, an operation of moving the drive device 58 from the storage position to the maintenance position when performing the maintenance work of the drive device 58 disposed in the box lower space Sd of the garbage truck 1 according to the second embodiment will be described. . Since the moving mechanism 110 is the same, a detailed description thereof is omitted.

The locking device 105 is released, and the vertical surface 101a of the front cover portion 101 is rotated upward. At this time, the buffer member 104 provided on the back surface of the vertical surface 101a also rotates together to release the battery 46 from being fixed by the buffer member 104, so that the battery 46 can slide. Then, the battery 46 is slid and moved to the maintenance position, and the battery 46 is held at the maintenance position on the side of the garbage collection vehicle 1, whereby the maintenance work of the battery 46 disposed in the box lower space Sd can be performed.
After the maintenance work is completed, the battery 46 at the maintenance position is slid and returned to the travelable state shown in FIG.

According to the garbage truck 1 according to the second embodiment configured as described above, the driving device 58 disposed in the box lower space Sd is covered by the side cover 100 from both outer sides in the vehicle width direction. Therefore, the driving device 58 can be protected by the side cover 100 so as not to interfere with obstacles on both outer sides (for example, roadside trees protruding on the road side). Therefore, it can suppress that the drive device 58 arrange | positioned in box lower space Sd is damaged by the said obstruction.
Moreover, since both the front cover part 101 and the rear cover part 102 which comprise the side cover 100 are attached to the dust container 2 side, if each cover part 101,102 is previously attached to the dust container 2, The cover portions 101 and 102 can be attached to the vehicle in a state of being united with the dust container 2. Therefore, it is not necessary to attach each cover part 101,102 and the dust container 2 to a vehicle separately, and the attachment work to a vehicle can be performed easily.

  Further, since the buffer member 104 is provided in the front cover portion 101, the battery 46 can be fixed at the storage position of the box lower space Sd only by fixing the front cover portion 101 with the lock device 105. The battery 46 can be moved only by releasing it, and maintenance work becomes easy. The buffer member 104 is configured to contact the driving device 58 (battery 46), but is configured to contact only the moving mechanism 110 or both the moving mechanism 110 and the driving device 58 (battery 46). May be.

Further, since the valve block 33 is arranged in the box lower space Sd, the center of gravity of the entire vehicle can be further lowered. Therefore, the running stability of the vehicle can be improved.
Further, since the hydraulic pipe 40 for supplying and discharging the hydraulic oil between the valve block 33 and the driving device 58 is arranged at the corners 2e and 2h which are relatively difficult to vibrate in the entire dust container 2, it is loaded. During the operation of the device T, it is possible to suppress resonance of vibration noise between the hydraulic pipe 40 and the dust container 2. Therefore, noise during loading work can be effectively reduced.

Further, since the hydraulic pipes 40 arranged at the corners 2e and 2h are covered from the outer side in the vehicle width direction by the cover member 110, the outer side obstacles are covered by the cover member 110. It can be protected so as not to interfere with (for example, a roadside tree protruding on the road side). Therefore, it is possible to suppress the hydraulic pipe 40 from being damaged by the obstacle.
Further, since the rear cover portion 101 of the side cover 100 that protects the driving device 58 is also used as a part of the cover member 110 that protects the hydraulic piping 40 (pipe portion 40a), the side cover 100 and the cover member 110 are also used. The manufacturing cost can be reduced.

  The present invention is not limited to the above embodiment. For example, the moving mechanism 110 supports the battery 46 so as to move from the storage position to the maintenance position. However, the moving mechanism 110 may support other driving devices so as to move, and at least the driving device in the lower space Sd. A part may be moved. Specifically, the parts (battery 46 and charger 50) arranged in the space under the box Sd may be fixed to the front part moving member 113 and may be supported so as to be slidable. The driving device 58 in the state may be supported so as to be slidable.

  In addition, the moving mechanism 110 is configured to slide a part of the driving device 58 in the above embodiment, but the rotating shaft facing the vehicle vertical direction is fixed to the vehicle body frame 1b side, and the moving member is attached to the rotating shaft. The driving device may be fixed to the moving member so as to be pivotable, and the moving member is supported by a link mechanism having a base fixed to the body frame side, and the driving device is fixed to the moving member. It may be. At this time, if at least the driving device arranged in the box lower space Sd is fixed to the moving member, the driving device arranged in the box lower space Sd can be easily maintained.

  As described above, in the two embodiments, the moving mechanism 110 is configured to support the battery 46 (a part of the driving device 58) at the maintenance position, but it is not necessary to support the battery 46 at the maintenance position. What is necessary is just to comprise so that it can move from the storage position of space Sd, and what is necessary is just to insert the protrusion part 46a of the battery 46 so that sliding movement is possible to the front part moving member 113, for example. At this time, if a work table is separately prepared at the maintenance position and the battery 46 is moved to the work table to perform the maintenance work, the maintenance work can be performed without being disturbed by the storage box 2.

  Further, the fastening means 80 and 81 detachably fix the support main body 61 to the front support 63 and the central support 64, but the support main body 61 is attached to the front support 63 and the central support 64. The front support part 63 and the center support part 64 can also be fixed to the attachment member 71 (base frame 72a) so as to be detachable. In this case, the rear lashing portion 78 may tie the base frame 72a to the vehicle body frame 1b instead of the central support portion 64.

Further, a part of the drive device 58 is disposed in the box lower space Sd. For example, the lower box space Sd is formed by forming the recess 66 long in the vehicle front-rear direction so as to widen the box lower space Sd. Alternatively, the entire drive device 58 may be disposed.
Moreover, although the support main body part 62, the front support part 63, the center support part 64, and the rear support part 65 are each comprised as a separate member, these can also be integrally formed.
Moreover, although the hollow part 66 is formed of the support main body part 62, the front support part 63, and the center support part 64, it can also be formed only by the support main body part 62 formed in bulk. In this case, a part of the support main body 62 may be cut out to form the recess 66, and the box lower space Sd may be formed by the recess 66 and the vehicle body frame 1b.
The box lower space Sd is formed by the vehicle body frame 1b and the recessed portion 66 opened downward. However, the box lower space Sd can be formed by forming a through hole in the support member 61.

Further, the box lower space Sd is formed between the front support part 63 and the center support part 64, but it can also be formed between the center support part 63 and the rear support part 65. For example, the front support portion 63 is disposed slightly rearward of the arrangement of the above embodiment to form a box lower space Sd in front of the front support portion 63, or the rear support portion 65 is slightly forward of the arrangement of the above embodiment. It is also possible to form the lower box space Sd behind the rear support portion 65 by arranging them in the rear. In the former case, since the box lower space Sd and the box front space Sf are formed as continuous spaces, the degree of freedom of arrangement of the drive devices 58 in these spaces can be increased.
The box lower space Sd is formed below the lower surface of the support main body 62, but is outside or inside in the vehicle width direction of the support main body 62, above the lower surface, and in the dust container box 2. The space below the bottom plate 2b may be a box lower space Sd.

The drive device 58 disposed in the box lower space Sd is attached to the box lower mounting portion 72 before the dust container 2 is mounted on the support member 61, but is attached after the dust container box 2 is mounted. You may be made to do.
Further, the drive devices 58 arranged in the box lower space Sd and the box front space Sf are attached to the vehicle body frame 1b via the box lower attachment portion 72 and the box front attachment portion 73, respectively. Of these, the drive device 58 disposed in one or both of the spaces may be directly attached to the upper surface of the vehicle body frame 1b.

    Moreover, although the bottom plate 2b of the dust container 2 is formed in a flat plate shape, a concave portion that opens downward is formed at both ends in the vehicle width direction, and the convex portions 46c and 46d of the battery 46 are accommodated in the concave portion. Is also possible. In this case, it is possible to more effectively suppress the increase in the overall height of the dust container box 2. Furthermore, if the concave portion is formed in the bottom plate 2b in front of the lower portion of the inclined portion 18a in a state where the discharge plate 18 has moved to the foremost position, the concave portion can be disposed in a dead space in front of the discharge plate 18. Therefore, it is possible to suppress an increase in the overall height of the dust container box 2 without reducing the storage space Sa in the dust container box 2 in front of the discharge plate.

Moreover, although the valve block 33 is being fixed to the dust container 2 side, you may be fixing to the vehicle body frame 1b side. In this case, if the connection between the valve block 33 and each cylinder 9, 12, 19, 31 is a flexible hydraulic hose instead of the hydraulic pipe 40, the above connection state is maintained when the dust container 2 is tilted. Can be maintained.
The drive device 58 operates all the cylinders 9, 12, 19, and 20 constituting the loading device T, but it is sufficient that at least one cylinder is operated.
Moreover, although the loading apparatus T is a press type which loads dust only with the pushing plate 8, it may be a rotating plate type which loads dust with the cooperation of the pushing plate and the rotating plate. In this case, the pushing plate, the rotating plate, and a cylinder and / or a motor for operating them constitute a part of the loading device T.
