JP 2008-69759 A

  However, when the oil breakwater as described above is formed integrally with the lower frame, it can be applied to a small engine working machine with almost no problem, but if it is applied to a large engine working machine, the engine housed in the casing Since heavy objects such as work machines and work machines must be supported by the lower frame, it is necessary to increase rigidity by increasing the thickness of members such as the bottom plate and the side plate that constitute the oil barrier. For this reason, since the manufacturing cost of a casing rises and a weight also increases, there is also a problem in transportation.

  Therefore, the present invention provides a support for an engine working machine that can obtain sufficient rigidity with a simple structure, can prevent fuel from flowing out to the outside, and can reduce manufacturing costs and improve transportability. The purpose is to provide a platform.

  To achieve the above object, an engine work machine support frame according to the present invention includes an engine work machine that houses a work machine, an engine that drives the work machine, and a fuel tank that stores fuel for the engine in a casing.

  According to the support frame for an engine work machine of the present invention, the load of the engine work machine can be supported by a plurality of leg members and a plurality of support members provided above and below the bottom plate, and the bottom plate and the side plate need to have a large rigidity. Therefore, even a gantry that supports a large engine working machine can use a thin plate for the bottom plate and the side plate, thereby reducing the manufacturing cost and improving the transportability by reducing the weight. Moreover, since the oil barrier is formed by the bottom plate and the side plate at the upper part of the gantry, even if fuel leaks from the engine working machine, it can be received at the upper part of the gantry and the fuel can be prevented from flowing out to the outside. .

  In particular, by making the bottom plate contact surfaces of the leg member and the support member the same shape and overlapping each other, the load from the support member can be directly received by the leg member, so that the bottom plate can be made thinner. it can. Further, by providing a connecting portion for connecting the casing, it is possible to transport the mounted engine working machine and the support frame in an integrated state.

  An engine work machine support frame (hereinafter referred to as a support frame) 21 on which the engine work machine 11 is placed has a width dimension and a depth dimension larger than the width dimension and the depth dimension of the lower frame 13 of the casing 12. A rectangular bottom plate 22, a pair of long side plates 23 erected from the opposing long sides of the bottom plate 22, a pair of short side plates 24 erected from the opposing short sides of the bottom plate 22, and the bottom surface of the bottom plate 22 Further, three leg members 25 provided at predetermined intervals in a direction parallel to the short side plate 24, and three supports provided on the upper surface of the bottom plate 22 so as to overlap the leg members 25. A pair of inverted U-shaped connecting portions 27 provided at both ends of the member 26 and the supporting members at the center of the three supporting members 26, a drainage portion 28 and a drain provided at the central portion of the short side plate 24. And a 9, on the upper side of the bottom plate 22, receiving tank 30 which four sides are surrounded by the long side plate 23 and the short side plate 24 is formed. The height of the long side plate 23 and the short side plate 24 is a volume that can receive all the fuel leaked from the engine working machine 11 in the receiving tank portion 30 on the bottom plate 22 surrounded by the long side plate 23 and the short side plate 24. It is set to be obtained.

  Both the leg member 25 and the support member 26 are made of channel steel having the same opening width with a length that can be accommodated between the long side plates 23, and facing both openings with the opening side facing the bottom plate 22. The bottom plate 22 is disposed above and below the bottom plate 22 with the edges 25a and 26a sandwiched from above and below, and the respective opening edges 25a and 26a are fixed to each other by welding to the bottom plate 22. The height of the leg member 25 is arbitrary. For example, it is preferable that the leg member 25 has a height that allows a forklift claw to be inserted between the bottom surface (grounding surface) of the leg member 25 and the bottom surface of the bottom plate 22.

  Further, the height of the support member 26 is to prevent the engine working machine 11 from being submerged or corroded by contact with water even when the receiving tank 30 is filled with water or the like. The upper end surface of the support member 26 is flush with the upper ends of the long side plate 23 and the short side plate 24, or is higher than the upper ends of the long side plate 23 and the short side plate 24. Further, the central support portion 26 of the three support members 26 is disposed so as to pass through the center of gravity of the support frame 21, and the connecting portion 27 provided on the support member 26 is connected to the support frame 21. On a straight line passing through the center of gravity, two are provided at symmetrical positions around the center of gravity.

  In addition, a cutout portion 26b obtained by cutting out the upper surface portion and the upper portion of the side surface is provided at both upper ends of each support member 26, and the end portion side of the cutout portion 26b is inserted below the upper end bent piece 23a of the long side plate 23. The front end edge is welded to the inner surface of the long side plate 23 with a gap provided between the upper surface portion of the support member 26 and the upper end bent piece 23 a of the long side plate 23. A semicircular through hole 26 c for forming a flow path between the support plate 26 and the bottom plate 22 is provided at the lower edge of each support member 26.

  The drainage part 28 is a drainage pipe which penetrates the upper part of the water collection part 28a which consists of the recessed part provided in the short side board 24 side of the baseplate 22, and the short side board 24, and the inner side opened near the bottom face of the said water collection part 28a. 28 b and a water receiving portion 28 c provided below the drain pipe 28 b opened at the upper part on the outer side of the short side plate 24.

  The support base 21 formed in this way directly receives the load of the engine work machine 11 applied to the support member 26 by the leg member 25 when the engine work machine 11 is placed on the upper surface of the support member 26. Since the work machine 11 can be supported, even when a large and heavy engine work machine 11 is placed, the load of the engine work machine 11 is applied to the bottom plate 22 and the side plates 23 and 24 of the support base 21 at all. There is nothing.

  Accordingly, the bottom plate 22 and the side plates 23 and 24 need only have rigidity capable of maintaining these shapes and holding the fuel leaked from the engine working machine 11. , 24 can be reduced in thickness, and the weight of the support frame 21 can be reduced and the manufacturing cost can be reduced.

  Further, when the engine work machine 11 is placed on the support frame 21, the connection fitting 18 provided on the casing 12 and the connection portion 27 provided on the support frame are connected by a connection means such as a connection wire 31. Thus, the engine working machine 11 and the support base 21 can be integrated. Thereby, when the engine work machine 11 is transported, the engine work machine 11 and the support work base 21 need to be lifted separately because the support work base 21 can be lifted at the same time when the engine work machine 11 is lifted by the suspension bracket 17. Therefore, workability during transportation and work time can be shortened. In particular, when the connecting portion 27 is provided at a position corresponding to the center of gravity of the support base 21, the engine work machine 11 and the support base 21 in an integrated state using the suspension bracket 17 of the engine work machine 11 are lifted. In addition, since the center of gravity is not moved by the support base 21, the engine work machine 11 and the support base 21 can be lifted and transported in a stable posture.

  In addition, when oil or fuel leaks from the engine work machine 11, fuel or the like can be received in the receiving tank portion 30 on the bottom plate 22 surrounded by the long side plate 23 and the short side plate 24. Can be prevented from leaking. At this time, since the fuel or the like that has flowed down to the upper surface of the support member 26 flows downward from the notch 26b, it does not flow out beyond the long side plate 23, and the through hole 26c is formed in the lower edge of the support member 26. Since the liquid level in the receiving tank portion can be made uniform, fuel and the like can be received by the entire upper surface of the bottom plate 22.

  Furthermore, when fuel leaks in a state where rainwater has accumulated in the receiving tank, fuel with a low specific gravity floats on the water, so that the liquid level in the receiving tank is from the external opening position of the drain pipe 28b. When it becomes higher, only water can be discharged from the drain pipe 28b to the outside from the bottom of the water collecting portion 28a, and leaked fuel or the like can be prevented from flowing out beyond the side plates 23 and 24.

  FIGS. 8 to 11 show a second embodiment of the present invention. Components that are the same as those in the first embodiment are designated by the same reference numerals, and detailed description thereof is omitted.

  The support frame 21 shown in the present embodiment is provided with two leg members 25 and a support member 26 in a direction parallel to the long side plate 23, and a pair of connecting portions 27 is provided on the upper surface of the center portion of both the support members 26. In addition, notches 26b similar to those described above are provided in the upper portions of both ends of each support member 26, and through holes 26c are provided in the lower edge portion.

  Thus, the arrangement of the leg member 25 and the support member 26 can be arbitrarily set, and the leg member 25 and the support member 26 can be combined in a square shape.

  In addition, the structure and shape of each member, the number of leg members and support members can be appropriately set according to the engine working machine having the maximum weight and the maximum bottom surface dimension of the engine working machine to be supported. For example, H-shaped steel or Z-shaped steel can be used for the leg member and the supporting member, or angle steel can be used in combination, and the bottom plate and the side plate are formed integrally by processing one metal plate. Is also possible. Moreover, the structure of a connection part or a waste_water | drain part is also arbitrary, for example, the connection part may be a through-hole which penetrates a wire and a bolt, and can also be provided in three or more places. Furthermore, the well-known oil-water separation means provided in the oil breakwater etc. can also be employ | adopted for a drainage part.
