Description of the Related Art Conventionally, an engine-driven work machine having a casing has an intake port that is an outside air intake port for internal cooling and an exhaust port that discharges air after cooling. Inlet for engine-driven working machine to protect the equipment that is disposed inside the housing from the rainwater to be used outdoors, air discharge opening and the door or the like ducts subjected to guttering and rainwater measures for rainwater immersion entering prevented Is arranged.

An example of a conventional example is shown in Patent Document 1, and in describing the invention, the designation is described by the notation of Patent Document 1. While preventing rainwater immersion entry into the soundproof case is disclosed as devised for not increasing the installation space of the engine-driven work machine.

In order not to increase the installation space for the engine-driven work machine, a rain gutter is provided above the intake port without forming a hood that covers the intake port on the intake port formed on the side wall surface of the soundproof case. receiving an upper portion of the from the transmitted drops rainwater housing from the gutter in該雨gutter, to drop the rainwater at a distance from the intake port, thereby preventing rainwater immersion incoming from inlet.

The idea of preventing rainwater immersion incoming from air discharge port facing upward to the ceiling surface of the soundproof case in Patent Document 2 is disclosed. According to the present invention, a plurality of inclined plates are installed at predetermined intervals in the exhaust outlet facing upward, and the inclined plates always fall into the inclined plates against rainwater that falls down within a predetermined angle. There has been disclosed a device in which a gutter that collects rainwater touching the gutter is formed at the lower end of the inclined plate and discharged to the outside from both ends of the gutter.

  As an example of another conventional example, FIG. 6 shows a structure in which rain gutters are formed in an intake duct 230 of an engine-driven work machine 200 installed as equipment, and FIG. 7 shows an enlarged view of the intake duct 230. In the engine-driven work machine 200, an engine 60 having a cooling fan on a base 205, which is a basic frame body, and a work machine main body 50 driven by the engine 60 are disposed in a casing.

  A roof member 210 is disposed on the upper part of the housing, and the roof member 210 is assembled by individual parts of the roof member pieces 210a, 210b, 210c, 210d, and 210e because the engine-driven work machine 200 is large. An air inlet 211 for sucking cooling air is formed at the right end of the roof member 210 in the figure, and an air exhaust port 212 for discharging the exhausted air after cooling to the outside is formed at the left end.

  In the intake port 211, the intake duct 230 is locked with the opening 230a downward for the purpose of preventing noise emitted to the outside and preventing the intrusion of rainwater that is sucked into the sucked air. Has been. On the lower end side wall surface of the intake duct 230, a gutter 230b with an opening facing upward is formed around the intake duct 230. The intake duct 230 collects rainwater during rain and has a relatively weak suction force of the cooling air Q1. Is discharged to both corners at the right end of the figure.

  In many cases, the engine-driven work machine is rarely fixed at the work site to be used, and is often carried and used at each work site. In such a case, it is preferred that the engine-driven work machine has no protruding portion such as a duct from the casing. Also, since ducts and gutters protrude from the housing, they are struck against surrounding buildings and other engine-driven work machines during lifting work or installation by an engine-driven work machine crane, etc. It may stop functioning or damage the opponent's structure.

  When the gutter is made of metal and the casing and gutter are welded, the joint surface cannot be painted and the joint surface needs to be caulked in order to suppress the occurrence of rust. In addition, when a metal gutter is fixed to the housing with a bolt or the like, if the gutter is long, a gap may be formed on the joint surface, and therefore caulking is necessary.

  Further, when the engine-driven work machine becomes large, the entire housing is divided into a plurality of constituent members, and each of the constituent members is coupled by a bolt or the like to form one housing. Among the constituent members, the constituent member (for example, the roof member) provided with the air inlet for sucking the cooling air is further divided into a plurality of small constituent member pieces having the same shape and divided into bolts. It becomes one component member by the coupling | bonding.

When the intake port is formed continuously with a plurality of small component pieces, when a rain gutter is provided as a measure against rainwater, it is passed through the wall surfaces of the plurality of small component pieces arranged side by side. Must be installed. However although a plurality of small components pieces having the same shape, there is a case where the outer shape dimensions are not necessarily finished in the same. In such a case, the small constituent member pieces are installed side by side and coupled with bolts or the like, and an assembly error is added, so that a step is naturally formed on the joint surface.

Since there also be subjected to such a small component pieces cross section arcuate coking as rise from the surface at the bonding surface full length as input prevention immersion rainwater on the joint surface of, impaired further flatness of the joint surface End up. In such a case, a metal gutter mounting by bolts, may not always Nara If Ne Kokinguse around the mounting surface after performing the gap adjustment takes time to mount. In addition, if the gap adjustment is insufficient, the gutter may be deformed.

Means to solve the problem

  In order to solve the above-described problems, according to the present invention, at least an engine, a work machine body driven by the engine, and a cooling fan are disposed in the casing, and the side wall surface of the casing In the engine-driven work machine in which the rain gutter is disposed, the rain gutter is formed of a flexible member, and the gutter has a substantially concave drainage groove with the opening facing upward, and the drainage gutter A rain gutter continuous with the lower end of the planar vertical wall, the outer surface of one side wall of the both side walls forming a flat vertical wall from the upper end of the side wall to the lower end extending downward from the bottom of the drainage groove. A hollow space is formed in the longitudinal direction of the gutter in a substantially middle region of the lump portion surrounded by the bottom surface and the bottom surface of the drainage groove.

Is formed of a resin material having flexibility, and is disposed at the upper portion of the air inlet formed toward the side wall of the housing.

  In order to solve the above-mentioned problems, according to the present invention, the present invention provides a rain gutter of an engine-driven work machine according to claim 2, wherein the bottom surface of the drainage groove is substantially the same as the vertical wall. Formed below the center position, one end of the bottom surface of the drainage groove is connected to the inner wall surface of the flat vertical wall, the other end is connected to the inner surface of the outer wall of the drainage groove, and the outer wall of the drainage groove is the contact point The drainage groove outer wall is extended outward so that the rain gutter width is maximized at the upper side.

  In order to solve the above-described problems, according to the present invention, as described in claim 4, it is a rain gutter of the engine-driven work machine according to claims 1 to 3, wherein the drain groove has the substantially concave shape. One side surface of the elastic member is attached to a flat vertical wall formed on one side wall of both side walls, and the other side surface of the elastic member is formed so as to be attached to the side wall surface of the casing of the engine-driven working machine.

  In order to solve the above-described problems, according to the present invention, as described in claim 5, the drainage groove of the engine-driven work machine according to claim 4, which is opposed to the planar vertical wall. A flat plate-like projecting piece facing downward from the bottom of the rain gutter is formed continuously in the longitudinal direction of the gutter below the outer surface connected to the outer wall.

  In order to solve the above-described problems, according to the present invention, as described in claim 6, it is a rain gutter of the engine-driven work machine according to claim 5, and is near the upper side of the bottom surface of the substantially concave drainage groove. At least two horizontal bolt mounting holes penetrating the planar vertical wall which is one side wall of the drainage groove are formed, and the fixing of the gutter is reinforced with bolts inserted into the bolt mounting holes.

The invention's effect

  The present invention has the following effects by being configured as described above.

  A gutter is formed of a flexible resin material, and a resin member between the bottom surface of the concave drainage groove used for drainage of rainwater and the bottom surface of the gutter located below the bottom surface of the drainage groove is formed as a lump. Since a hollow space is formed in a substantially intermediate region of the existing portion, it is possible to provide a rain gutter that is flexible and expected to have a restoring force while having a reaction force against a pressing force in a direction penetrating the lump portion. .

  For this reason, even if the engine-driven work machine is lifted by a crane or the like and hits nearby buildings during installation, the rain gutter itself and the opponent are less likely to be damaged, and the resilience itself is excellent. Loss of function as a gutter can be reduced by deformation.

  The drainage groove outer wall of the drainage groove facing the vertical wall that is the attachment surface of the gutter is formed by projecting the drainage groove outer wall outwardly so that the drainage groove width is maximized above the bottom surface of the drainage groove, It is the most protruding part from the side wall of the housing of the drive work machine.

With this configuration, when the maximum protrusion of the rain gutter disposed on the side wall surface of the casing is struck by another structure from a substantially horizontal direction, the bottom surface of the drain gutter having a reaction force is formed into the planar shape. It is deformed so that the whole rotates inward with the intersection with the vertical wall as a supporting point. Planar vertical wall of the upper than this time fulcrum is never so it is no Ru peeling the stuck by an elastic member so the direction to be pressed against the housing side wall rainwater soak than guttering top.

  At this time, the planar vertical wall below the fulcrum works in the direction of peeling, but even if the adhered elastic member is peeled off, the upper part of the fulcrum is securely attached, so rainwater from above There is no need to worry about the intrusion.

  A flat plate-like projecting piece that faces the bottom of the gutter bottom surface is formed below the outer surface of the drainage groove outer wall facing the flat vertical wall that is the attachment surface of the gutter. Since the raindrops touching the outer surface are transmitted along the protruding pieces and fall directly below, they are not transmitted to the intake port formed on the side wall surface of the casing through the bottom surface of the rain gutter.

  Bolts for fixing the housing side wall surface and the rain gutter are arranged horizontally from the inside of the drainage groove of the vertical wall formed as a flat surface as the mounting surface, near the upper side of the bottom surface of the drainage groove. Therefore, the vicinity of the fulcrum where the bottom surface of the drainage groove intersects the flat vertical wall is pressed against the side wall surface of the housing by the bolt, so even when a horizontal external force is applied to the gutter The fulcrum portion is stably pressed.

  Since the rain gutter is formed of a flexible resin material, it is possible to attach the gutter without any gaps without worrying about the flatness of the housing side wall surface, which is the affixing surface. In addition, when the engine-driven work machine is large and the casing part that forms the air inlet is assembled with a plurality of small component pieces, and the caulking process is performed on the casing joint surface, a step is partially generated, The rain gutter which can absorb and stick to this level | step difference can be provided.

Rain gutters can be securely attached to the housing surface without gaps, and the elastic member usually uses a porous material formed of closed cells, so that it is possible to eliminate water permeation of the elastic member itself and water permeation through the gap. Because it can, you can omit the caulking work, and the finish will be better. In addition, since the bolt head is disposed inside the concave groove, it is not visible from the outside and the aesthetic appearance is not impaired.

BEST MODE FOR CARRYING OUT THE INVENTION

  Examples of the present invention will be described below with reference to FIGS.

  FIG. 1 shows an embodiment of the present invention, which shows a side view of an engine-driven working machine in which a rain gutter is disposed on a side surface of a casing, and will be described in detail below. The engine-driven work machine 100 is formed by a base 110, a lower frame 120, an upper frame 130, and the like, which are part of the casing. On the base 110 inside the housing, an engine 60, a work machine main body 50 driven by the engine 60, a cooling fan 61, a radiator 62, an electrical component storage box 70, and the like are disposed.

  Since the lower frame 120 has a large engine-driven work machine 100, a plurality of lower frame pieces 121, 122, 123, and 124 and a lower frame piece 125 are respectively fastened with bolts. The frame is provided with a door for inspecting the inside of the housing as necessary.

  Since the upper frame 130 is also large in size, the upper frame 130 is composed of a plurality of small frame member pieces 131, 132, 133, 134, and 135 that are fastened with bolts (not shown) to form a single upper frame 130. ing.

  Since the engine-driven work machine 100 is often installed outdoors, the upper frame 130 which is a ceiling surface is a strip-shaped coking member whose section is raised in an arc along the outer peripheral joint surface of the upper frame pieces. 160 is continuously applied to prevent rainwater from entering the housing.

  Air inlets 136 and 137 for sucking cooling air are formed on the side wall surfaces of the upper frame piece 134 and the upper frame piece 135, and the inside of the housing is cooled through a ventilation path (not shown) and discharged to the outside from the air exhaust port 131a. The A rain gutter 80 is arranged above the intake ports 136 and 137 from the upper frame piece 132 to the upper frame piece 135.

  2 is a cross-sectional view taken along the line AA shown in FIG. 1, and FIG. 3 is an enlarged view of the gutter 80 shown in FIG. 2, which will be described in detail below. An intake port 137 for sucking cooling air is formed on the side wall surface 135a of the upper frame piece 135 with a swash plate 137a for preventing rainwater from entering. A rain gutter 80 that collects rainwater flowing down from the ceiling surface or the like above the intake port 137 is disposed on the side wall surface 135 a of the upper frame piece 135 after the elastic member 85 is adhered.

  As shown in FIG. 3, the rain gutter 80 disposed on the side wall surface 135a of the upper frame piece 135 has a substantially concave drainage groove 80e facing upward, and forms the drainage groove 80e. The wall surface is flat and forms a vertical wall 80a extending downward from the bottom surface 80f of the drainage groove. One surface of the elastic member 85 made of closed cells is attached to the outer wall surface of the vertical wall 80a, and the other surface is attached to the sidewall surface 135a. Further, a rain gutter is screwed between the bolt 92 and a nut 93 fixed to the side wall surface 135a.

  A hollow space 80c is formed in the longitudinal direction of the rain gutter 80 in a substantially intermediate region surrounded by the drain groove bottom face 80f and the bottom face 80k of the rain gutter 80 connected to the lower end of the vertical wall 80a. After the drainage groove outer wall 80d facing the vertical wall 80a is connected to the right end of the bottom surface 80f of the drainage groove and extends outward while extending upward, the drainage groove 80e is widened to form the maximum groove width. The width of the drainage groove 80e is narrowed at the upper position.

  The lower side of the drain groove outer wall 80d extends to the bottom surface 80k of the gutter. At the boundary between the drain groove outer wall 80d and the rain gutter bottom surface 80k, a flat plate-shaped projecting piece 80g facing downward is formed to drop water drops flowing down along the surface of the drain groove outer wall 80d.

  When a force is applied from the inside of the drain groove outer wall 80d in the direction of the arrow F1 to the arrow F2, the drain groove outer wall 80d falls down like a drain groove outer wall 80j indicated by an imaginary line, so that the bolt 92 can be inserted. When the force in the direction F1 is removed, the drain groove outer wall 80j returns to the drain groove outer wall 80d, which is the original position indicated by the solid line.

  Below the drain groove bottom surface 80f, a lump portion 80b having a hollow gap 80c is formed in a substantially central portion. The lump 80b has a repulsive force against an external force as compared with other rain gutters and acts as a shock absorbing material against an impact. It helps to protect the machine against external forces caused by the bumps that occur when the engine-driven work machine is moved or transported, and also reduces damage to the counterpart structure. Thus, the gutter 80 is a gutter having a function as a buffer material.

  4 is a view taken in the direction of arrow P shown in FIG. 1 and shows a state before the rain gutter 80 is attached. There is a manufacturing dimensional error between the upper frame piece 134 and the upper frame piece 135 to be joined, or between the side wall surface 134a of the upper frame piece and the side wall surface 135a of the upper frame piece generated during assembly. The step d1 may occur due to the deviation.

  Further, a caulking member 160 is continuously applied along the joint portion as a rainwater countermeasure at the joint portion between both upper frame pieces, and the cross section of the caulking member is constructed so as to rise in an arc shape from the surface. A raised portion 160a of a caulking member 160 that gently covers the step d1 is formed at the portion where the step d1 occurs.

  FIG. 5 shows a state in which a gutter 80 is attached to FIG. An elastic member made of synthetic rubber with a gutter 80 facing the opening of the substantially concave drainage groove 80e across the side wall surface 134a of the upper frame piece having the step d1 and the side wall surface 135a of the upper frame piece. 85 is affixed to the vertical wall 80a of the rain gutter 80 and is arranged in close contact with each side wall surface of the upper frame.

  The rain gutter 80 is formed of a vinyl chloride resin having a predetermined hardness by adding a plasticizer. The gutter 80 has an upper surface which is a mounting surface while having flexibility together with an elastic member 85 made of synthetic rubber stuck to the vertical wall 80a. It absorbs deformations and steps on each side wall of the frame. In order to ensure the close contact state of the stepped portion of the mounting surface and the raised portion 160a of the caulking portion, the bolt 92 is inserted and fixed from the inside of the drainage groove 80e to the nut 93 fixed to the housing side.

  In describing the shape of the rain gutter 80, the stepped portion d1 of the upper frame, and the shape of the caulking member 160, each main portion is exaggerated. Further, in the embodiment, an example in which the rain gutter 80 is disposed so as to straddle a plurality of joined upper frame pieces is disclosed, but it goes without saying that the mounting surface formed by one flat member is also effective. Needless to say, when the elastic member 85 to be attached is a flat mounting surface formed of a single member, a thin double-sided tape or the like can be used.

FIG. 1 is a side view of an engine-driven work machine showing an embodiment of the present invention. 2 is a cross-sectional view taken along line AA shown in FIG. 3 is an enlarged view of the gutter 80 shown in FIG. 4 is a view taken in the direction of arrow P shown in FIG. 5 is a diagram in which rain gutters are arranged in FIG. FIG. 6 shows a conventional example in which rain gutters are formed in the intake duct. 7 is an enlarged view of the rain gutter portion of the conventional example shown in FIG.
