Description

The present invention relates to an engine working machine, and more particularly to an engine working machine in which an oil guard is arranged below an engine for driving the working machine.

Conventionally, in an engine working machine, in order to prevent the oil leaked from the engine from leaking to the outside, an oil guard for receiving the oil is provided at the lower part of the casing.

Further, cleaning and inspection of the box-shaped oil guard having an open upper portion can be performed through an inspection door provided on the casing, and the oil guard and the casing are fixed with bolts so as to be removable. There was something that was there. (See, for example, Patent Document 1.).

Japanese Patent No. 5642614

However, in the engine working machine of Patent Document 1, it takes time and effort to bolt the oil guard and the casing. In addition, since the oil guard has a large bottom area and is made of a plate material that is thinner than the casing, when the oil guard and the casing are welded, the engine work machine is lifted and moved by a crane or the like. If this is done, the oil guard may be distorted and damaged, or the oil accumulated in the oil guard may leak to the outside.

Therefore, an object of the present invention is to provide an engine working machine capable of integrating the casing and the oil guard in a simple process and ensuring the strength of the oil guard when it is lifted by a crane. ..

In order to achieve the above object, in the engine working machine of the present invention, the working machine and the engine for driving the working machine are housed on a pedestal provided at the lower part of the casing, and an oil guard is provided below the engine. In the arranged engine working machine, the gantry has a pair of side frames that support both sides of the casing in the longitudinal direction, and a plurality of equipment support frames that are bridged over both side frames, and the oil guard is rectangular. A plurality of boxes formed in a box shape having an opening at the upper part consisting of a bottom plate having a shape and side plates erected on four circumferences of the bottom plate, and having both ends projecting from the side plates at the bottom plate orthogonal to the side frame. The oil guard support frame is welded, the oil guard support frame and the side frame are welded , and the oil guard forms a drain port mounting portion over the side plate and the bottom plate facing the side frame. A drain port protruding outward is projected from the drain port mounting portion, and a drain port insertion hole is formed in the side frame. The drain port is outside with the tip side inserted into the drain port insertion hole. It is characterized by protruding toward the direction .

According to the engine working machine of the present invention, the oil guard support frame is welded to the bottom plate of the oil guard, and the oil guard support frame is welded to the side frame to integrate the oil guard and the casing. And the oil guard can be integrated in a simple process. Furthermore, the strength of the oil guard can be ensured by the oil guard support frame, and when the engine work machine is lifted and moved by a crane or the like, the oil guard is distorted and damaged, or the oil accumulated in the oil guard is removed. There is no risk of leakage to the outside.

In addition, since the tip side of the drain port provided on the oil guard is inserted into the drain port insertion hole formed in the side frame, the drain port is connected to the side frame to provide a function to prevent the oil guard from falling off. Can be done.

It is sectional drawing side view of the engine working machine which shows the example of one embodiment of this invention. FIG. 2 is a sectional view taken along line II-II of FIG. It is a main part plan view of the engine working machine which shows the example of one embodiment of this invention. Similarly, it is a side view of a main part of an engine working machine. It is a VV sectional view of FIG. FIG. 6 is a sectional view taken along line VI-VI of FIG.

1 to 6 are views showing an example of one form of the engine working machine of the present invention. The engine working machine 11 includes a generator (not shown), which is one of the working machines, and an engine 14 for driving the generator, on a gantry 13 provided under the casing 12 having a soundproof structure. It houses equipment such as a fuel tank 15 and a radiator 16. Further, an oil guard 17 is arranged below the engine 14.

The casing 12 is formed in a substantially rectangular parallelepiped box shape, and a plurality of inspection doors for performing maintenance and inspection work of the equipment are provided on the side wall. The gantry 13 has a pair of side frames 13a and 13a that support both sides of the casing 12 in the longitudinal direction, and a plurality of device support frames 13b that are bridged over the upper portions of both side frames 13a and 13a.

The oil guard 17 is formed in a box shape having an opening at the upper part including a rectangular bottom plate 17a and side plates 17b erected on the four circumferences of the bottom plate 17a. Further, two oil guard support frames 17c and 17c which are orthogonal to the side frame 13a and whose both ends project outward from the side plate 17b are welded to the bottom plate 17a, and both ends of the oil guard support frames 17c and 17c are welded. Is welded to the side frames 13a and 13a, so that the oil guard 17 is fixed to the casing 12 and integrated. Further, a gap is formed between the oil guard 17 and the side frame 13a.

Further, drain port mounting portions 17d and 17d are formed over the side plate 17b and the bottom plate 17a facing the side frame 13a in the vicinity of the corner portions at diagonal positions of the oil guard 17, respectively, and the drain port mounting portions 17d are formed. Drain ports 18 are projected from each of the two. The drain port 18 includes a cylindrical portion 18a welded to the drain port mounting portion 17d, a tip member 18b screwed to the tip of the cylindrical portion 18a, and a plug body 18c screwed to the tip member 18b. ing. Further, the side frame 13a is formed with a drain port insertion hole 13c through which the tip member 18b is inserted.

Each drain port 18 inserts a tip member 18b into which a plug body 18c is screwed into the tip from the outside of the side frame 13a toward the cylindrical portion 18a welded to the drain port mounting portion 17d into the drain port insertion hole 13c. It is attached to the oil guard 17 by being screwed into the cylindrical portion 18a.

This embodiment is formed as described above, and by providing the oil guard 17 below the engine 14, oil and cooling water leaked from the engine 14 are dropped onto the oil guard 17 and collected via the drain port 18. can do. Further, the oil guard 17 can be cleaned and inspected by opening the inspection door (not shown) provided in the casing 12.

Further, the oil guard support frame 17c is welded to the bottom plate 17a of the oil guard 17, and both ends of the oil guard support frame 17c are welded to the side frame 13a to integrate the oil guard 17 and the casing 12. The casing 12 and the oil guard 17 can be integrated in a simple process. Further, since the strength of the oil guard 17 can be ensured by the oil guard support frame 17c, the oil guard 17 may be distorted and damaged when the engine working machine 11 is lifted and moved by a crane, or may be inside the oil guard 17. The accumulated oil does not leak to the outside.

Further, the oil guard 17 is provided with a drain port 18 projecting outward, and the tip member 18b of the drain port 18 is inserted into the drain port insertion hole 13c formed in the side frame 13a. Since the drain port 18 is inserted into the drain port insertion hole 13c even if it is about to come off from the casing 12, the drain port 18 is connected to the side frame 13a to provide a function to prevent the oil guard 17 from falling off. can.

The engine working machine of the present invention is not limited to the above-mentioned embodiment, and may be provided with three or more oil guard support frames on the bottom plate of the oil guard. Further, the position where the drain port is provided on the oil guard is arbitrary, and the tip end side of the drain port may not be inserted into the side frame.
