The pile driving machine 11 shown in the present embodiment includes a base machine 15 composed of a lower traveling body 13 provided with a crawler 12 and an upper revolving body 14 provided on the lower traveling body 13 so as to be rotatable, and an upper turning A leader 16 provided at the front of the body 14 and a pair of left and right back stays 17 that support the leader 16 in the working state from the rear side of the base machine 15. A battery storage unit 19 for storing the batteries 18 is provided.

  The upper swing body 14 has an opening 21 defined by an opening frame 20 on one side wall 14a, and an opening / closing door 23 can be opened and closed on one vertical frame 20a of the opening frame 20 via a vertical hinge 22. Is attached. The battery storage unit 19 is provided inside the opening / closing door 23, a support base 24 on which two batteries 18, 18 can be placed, and an upper part of the support base 24, and the two batteries 18, 18 are connected to each other. A fixing member 25 for fixing, and a guide member 26 for guiding the batteries 18 and 18 outward from the battery storage portion 19 in a state where the opening / closing door 23 is opened are provided.

  The battery 18 is a well-known battery formed in a rectangular parallelepiped shape, and a handle 18a is provided on each of the upper portions of the front surface and the rear surface. The fixing member 25 is disposed on the battery mounting tray 27 on which the two batteries 18 and 18 are placed side by side in the front-rear direction of the upper swing body 14 and on the upper surface of the batteries 18 and 18 mounted on the battery mounting tray 27. Presser plates 28, 28, and four clamp members 29 that connect the presser plates 28, 28 and the battery mounting tray 27, respectively.

  The battery loading tray 27 includes first frame bodies 27 a and 27 a that surround the outer side surfaces of the batteries 18 and 18 that are arranged in the front-rear direction of the upper swing body 14, and a second frame that surrounds the rear surfaces of both the batteries 18 and 18. The body 27b and the partition plate 27c that partitions the batteries 18 and 18 are provided, and the upper surface and the open / close door side surface are open. Each of the first frame bodies 27a is formed with engaging portions 27d and 27d for engaging the clamp member 29 on the outer surface at corresponding positions. The presser plate 28 is disposed with a predetermined interval in the direction orthogonal to the first frame bodies 27a and 27a, with both ends projecting outward from the first frame bodies 27a and 27a, and the first frame body 27a. , 27a, insertion holes are formed in both end portions. The clamp member 29 includes a bolt member 29b having a J-shaped hook 29a at a lower end portion, and a clamp wing nut 29c that is inserted into the insertion hole of the presser plate 28 and screwed into the male screw portion protruding upward. I have.

  The guide member 26 is attached to the lower end of the first frame 27a, 27a on one side of the opening / closing door so as to be pivotable in the vertical direction by a hinge 30. When the battery is fixed, the guide member 26 is in a vertical state with respect to the battery mounting tray 27. At the same time, the wing nuts 31, 31 are fixed to one end portions of the first frame bodies 27 a, 27 a of the battery loading tray 27. The guide member 26 is formed by fixing a resin plate 26b to the surface of the metal plate 26a, and guide grooves 26c and 26c for guiding the movement of the batteries 18 and 18 are formed on the surface of the resin plate 26b.

  The above-described pile driver 11 is in a state where the batteries 18 and 18 are accommodated in the battery accommodating portion 19 and the open / close door 23 is closed during operation and traveling. At this time, the batteries 18 and 18 are placed on the battery placement tray 27, the press plates 28 and 28 are disposed on the upper surface, and the hooks of the bolt members 29b are engaged with the engaging portions 27d of the first frames 27a and 27a. 29a is engaged, and the front end of the bolt member 29b is protruded from the bolt insertion hole of the presser plate 28, and the clamp wing nut 29c is screwed to the front end of the protruded bolt member 29b. Accordingly, the batteries 18 and 18 are pressed against the battery placement tray 27 by the presser plates 28 and 28, and the movement of the batteries 18 and 18 in the longitudinal direction of the vehicle body is performed by the first frame bodies 27a and 27a and the partition plate 27c. Be regulated. Further, the guide member 26 is arranged in a vertical state at one end of the battery loading tray 27 on the opening / closing door side, fixed to the first frame bodies 27a and 27a by wing nuts 31 and 31, and the front surfaces of the batteries 18 and 18; The guide groove 26c of the guide member 26 comes into contact with the guide member 26, and the movement of the batteries 18 and 18 in the vehicle body width direction is restricted by the guide member 26 and the second frame 27b. This prevents the batteries 18 and 18 from moving or vibrating in the battery storage unit 19 when the pile driving machine 11 is working or running.

  Further, when the batteries 18 and 18 are to be moved from the battery storage portion 19 to the outside in order to perform inspections and replacement of the batteries 18 and 18 and replenishment of the battery liquid, the open / close door 23 is opened and the wing nuts 31 and 31 are opened. , And the guide member 26 arranged in a vertical state with respect to the battery placement tray 27 is rotated so that the front end side is placed on the lower frame 20b of the opening frame 20 to be in a horizontal state. Further, each of the clamping wing nuts 29c is removed from the tip of the bolt member 29b, and the holding plates 28, 28 are removed, thereby making the batteries 18, 18 movable. Next, the handle 18 a provided on each battery 18 is pulled to the door side, and each battery 18 is slid along the guide grooves 26 c and 26 c formed on the resin plate 26 b of the guide member 26. By moving in the direction, it is possible to easily perform operations such as inspection and replacement of the batteries 18 and 18 and replenishment of battery fluid.

  As described above, the present embodiment can easily and reliably fix the batteries 18 and 18 by the fixing member 25 and the guide member 26 arranged in the vertical state when the pile driving machine 11 is operated or moved. The batteries 18 and 18 are prevented from moving or vibrating in the battery housing portion 19, and there is no possibility that the batteries 18 and 18 are damaged. Further, when performing operations such as inspection and replacement of the batteries 18 and 18 and replenishment of the battery liquid, the guide member 26 simply pulls the handles 18a and 18a of the batteries 18 and 18 to lower the lower frame 20b of the opening frame 20. Since the batteries 18 and 18 can be easily moved outward from the opening / closing door 23 by sliding on the guide member 26 supported by the operator, even in the case of a large battery provided in a large work machine, Can be reduced and workability can be improved. Further, since the guide member 26 is supported by the lower frame 20b of the opening frame 20, the number of parts can be reduced and the stability can be improved as compared with the case where a separate support member is provided.

  The present invention is not limited to the above-described embodiment, and the number of batteries stored in the battery storage unit is arbitrary, and the size of the support base and the shape of the battery mounting tray are appropriately changed depending on the number of batteries. do it. The presser plate and the clamp member may have any structure as long as the battery can be detachably fixed. Further, the guide member may be provided with no guide groove on the surface of the resin plate, or the guide member may be formed of a metal plate. Moreover, it can be applied to various construction machines such as cranes other than pile driving machines.
