Description

The present invention relates to a novel multi-demolition machine suitable for dismantling various objects to be dismantled, such as scrapped automobiles, construction waste materials, and piping waste materials, at various sites and the like.

It is an old story now, but in the scrap dismantling work of scrapped cars, piled up scrapped cars are lowered one by one to the ground with a crane, carried sideways by a transport vehicle, and cut torch etc. at the scrap factory workshop. , It was cut to an appropriate size, or the engine parts were removed.

In response to such a situation, the present inventor has a pair of left and right working arms that can be opened and closed by power at the front or rear of a self-propelled vehicle equipped with a hydraulically actuated boom having an opening / closing work pencher at the tip so that it can turn and undulate. A pair of facing cups for holding the scrap object by rotatably sandwiching it from both sides, a pair of breaking tools for crushing or breaking the scrap object by strongly pressing it from both sides, etc. , Has already proposed a dismantling machine equipped with various work hands (see, for example, Patent Document 1). The proposed dismantling machine and other improved dismantling machines that followed have dramatically improved the efficiency of scrap dismantling work, and made it possible to separate and collect scrap by material with high efficiency.

In recent years, not only scrapped automobiles but also various other scrap objects such as home appliances such as refrigerators and washing machines, construction waste materials such as reinforcing bars and window frame sashes, and piping waste materials such as water supply pipes and water distribution pipes, etc. However, it could not be processed by normal dismantling work, and various scrap objects were accumulated in various places and were waiting for dismantling.

In conventional dismantling machines, the electric motors and compressors inside these can not be taken out directly by the opening and closing work pencher at the tip of the hydraulically operated boom, and processing such as dismantling by another manual or unavoidably disposing of them as one without sorting is performed. It was done.

Under such circumstances, the present inventor expands the handling range of separate collection of scrap objects in terms of dimensions and strength, and efficiently performs separate and dismantling work of various scrap objects including scrapped vehicles. We have also proposed a multipurpose scrap dismantling machine that can be used (see, for example, Patent Document 2).

In addition, the present inventor can open and close the undulating drive equipped on the front or rear of the vehicle as a multi-purpose demolition machine suitable not only for dismantling automobile scrap but also for separating and dismantling construction waste materials. We have already proposed a dismantling machine equipped with a cutting shear that cuts a scrap object at a position near the arm pivot fulcrum of a pair of driveable left and right work arms (see, for example, Patent Document 3).

Special Fair 3-78460 Gazette Japanese Patent No. 3101717 Japanese Patent No. 4737751

Furthermore, in recent years, the momentum for recycling of resources has increased, and it is required to separate and collect waste automobiles, construction waste materials, piping waste materials, etc. as reusable raw materials rather than landfilling the waste materials. For example, in the dismantling of a reinforced concrete building, the distribution lines stretched around each section inside are used as copper resources, window sashes and partition panel frames are used as aluminum resources, and handrails and fireproof doors are used. The steel frame itself can be reused as an iron resource.

However, with the conventional cutting scissors as described above, when transporting high-strength aluminum or high-strength steel frame from the dismantling site, it is possible to cut the scissors to an appropriate size so that they can be mounted on a transport vehicle such as a truck. Sometimes I couldn't.

It is explanatory drawing explaining the structure of one Example of the multi-disassembly machine of this invention, FIG. aa is a side view, and FIG. b is an enlarged view of a main part. It is a top view of the multi-demolition machine shown in FIG. FIG. 1 is an explanatory view showing a configuration of a shearing tool means of the multi-demolition machine shown in FIG. 1, FIG. 1A is a side view, and FIG. B is an explanatory view showing a shearing operation. It is explanatory drawing explaining the structure of another Example of the multi-demolition machine of this invention, FIG. aa is a side view, and FIG.

In the present invention, a hydraulically actuated boom mounted on a self-propelled vehicle so as to be able to turn and undulate, a scrap dismantling work pencher attached to the tip of the boom and opened and closed by remote operation, and a front or rear portion of the vehicle. It is a multi-demolition machine equipped with a shearing tool means that is equipped to be able to drive undulations and can shear scrap objects.

The support structure of the shearing tool means of the present invention may be any one that is undulatingly driven at the front or rear of the vehicle and is capable of shearing the scrap object. In order to enable the undulating drive, a fulcrum as the rotation center of the undulating drive and a force point that receives the force of the hydraulic actuator that expands and contracts at a height position lower than this fulcrum may be provided. As a result, when the hydraulic actuator extends, the tip of the shearing tool means is lifted around the fulcrum as an action point. As a hydraulic actuator, it is possible to apply a large force to extend it rather than to reduce it, so that there is an advantage that shearing work can be performed satisfactorily.

The tip structure of the shearing tool means of the present invention includes a first jaw portion and a second jaw portion for shearing a scrap object with a shearing blade equipped so as to rotate relatively between an open position and a closed position. Any one provided with a hydraulic drive means for rotating the first jaw portion and / or the second jaw portion may be used. When both the first jaw portion and the second jaw portion are opened and closed, each hydraulic drive means must be provided, so that the shearing tool means itself becomes heavy. Therefore, a mechanism for opening and closing only one of the first jaw portion and the second jaw portion, more preferably only the first jaw portion provided with the tip blade is preferably used.

As a specific structure of the shearing tool means of the present invention, the shearing blade of the first jaw portion has the same maximum width as the thickness of the first jaw portion, and the tip penetrates into the scrap to be sheared. The blade, a pair of first shear blades bent at an oblique angle with respect to the invasion direction of the tip blade and arranged on both sides of the first jaw portion, and an oblique angle with respect to the first shear blade mounting portion. It is provided with a pair of second shear blades that are bent and arranged on both sides of the first jaw portion.

Further, as the shearing blade of the second jaw portion, it is possible to pass through the entire tip blade and the pair of the first shearing blades and a part of each of the pair of the second shearing blades when moving relative to the first jaw portion. Both the outer peripheral surfaces of the tip blade receiving blade and the first shear blade, which are arranged on the inner wall surface of the groove portion in the region other than the groove portion through which the first shear blade passes so as to surround the receiving groove portion and the outer peripheral surface of the passing tip blade, pass through. A pair of first shear blade receiving blades arranged along the inner wall surface of the groove portion in the region to be subjected to, and a pair of first shear blade receiving blades arranged along the inner wall surface of the groove portion in the region through which both outer peripheral surfaces of the second shear blade pass. It is provided with a pair of second shearing blade receiving blades.

The first jaw portion and the second jaw portion allow the tip of the tip blade of the first jaw portion to come into contact with the object to be sheared at the start of shearing, so that the pressure of the hydraulic drive system can be concentrated on this tip. Shearing a strong scrap object can also be easily performed. That is, only the tip of the tip blade of the first jaw portion comes into contact with the high-strength scrap object, so that hydraulic pressure can be concentratedly applied to this portion, and a drilling hole is formed. Following the formed drilling hole, it can be satisfactorily sheared by the first shearing blade and the first shearing blade receiving blade.

The tip of the tip blade of the first jaw portion is pressed in a substantially vertical direction with respect to the scrap to be sheared, so that the tip does not come off from the pressed portion and the hydraulic pressure is satisfactorily concentrated on the pressed portion. Can be made. That is, in cutting a high-strength scrap object, the tip of the tip blade of the first jaw portion is pressed against the cutting portion and the pressure is concentrated on this tip so that the tip does not come off from the pressing portion and the tip A drilling hole is easily formed by the blade, and a high-strength scrap object is sheared by the first shear blade and the second shear blade behind the tip blade. If the second jaw portion can also be opened and closed, there is an advantage that the degree of opening and closing can be adjusted according to the thickness of the scrap object.

In the shearing tool means of the present invention, preferably, the shearing blade of the first jaw portion as the tip blade has the same maximum width as the thickness of the first jaw portion, and the tip penetrates into the object to be sheared. All you need is. In a preferred embodiment, the tip blade is arranged on both sides of the edge surface having a blade width smaller than the thickness of the first jaw portion which is arranged at the tip of the first jaw portion and first contacts the sheared object. A cutting edge with a pair of tip tapered blades whose blade width is continuously increased toward the rear end, and a blunt angle bend with respect to each attachment portion of the rear end of the tip tapered blade of the cutting edge. Each of the first shear blades is provided with a pair of tapered blades arranged in a direction to separate from each other.

As a result, the pressing force of the hydraulic drive system is satisfactorily generated as shear stress on the edge surface and the width receiving blade having a width smaller than the thickness of the first jaw portion, and even a high-strength scrap object can be easily sheared. The tip of the tip blade penetrates and a drilling hole is formed. Therefore, the edge surface of the tip blade of the first jaw portion first abuts on the sheared object to drill a high-strength scrap object, and then widens the hole in which the pair of tip tapered blades are bored. Then, while cutting with a pair of tapered blades, the width of the first shear blade is expanded.

As a result, by driving the first jaw portion in small steps, it is possible to break while making a large number of drilling holes on the edge surface of the tip blade, and after a large number of drilling holes are formed, it is cut with a pair of tapered blades. While expanding to the width of the first shearing blade, the high-strength scrap object can be sheared by the first shearing blade and the second shearing blade.

The shear angle, which is the opening angle of the shear blades of the present invention facing each other, is a force required for cutting by angling one side of the blade (usually the movable side) in the straight blade. By reducing the number of blades and cutting continuously from one direction, a clean cut can be obtained. Increasing the shear angle reduces the "maximum shearing force" and the power of the shear (cutting machine), but as the shear angle increases, the bending and twisting during cutting increases, and the plate dimensions begin to cut. The quality and quality of the sheared product deteriorates, such as being different on the cutting end side.

Further, the quality of the cut edge, the required shearing force, the lateral force, and the like change depending on the size of the clearance between the shearing blades of the present invention. In a shearing machine, the standard value of the clearance value is often shown by the plate thickness to be cut and some steel type classification, but the properties of the cut end due to the difference in mechanical properties of the material to be cut, mechanical accuracy, plate holding force, etc. Select the optimum clearance because the quality) will change. For example, a clearance of 20% of the thickness is taken with respect to the plate thickness of 20 mm.

Further, the tip blade of the first jaw portion abuts its edge surface on the sheared object with a strong pressure, concentrates the pressure of the hydraulic drive system on this tip to shear the sheared object, and from the edge surface to both sides thereof. The hole formed by the pair of tip taper blades formed over is widened, and further widened to the width of the first shear blade while cutting with the pair of tapered blades. Therefore, since a strong force is applied to the tip blade, the life of the tip blade can be extended if the outside of the tip in the rotation direction is reinforced as compared with the inside. As the reinforcement, the outer side may be thicker than the inner side, or a reinforcing material made of the same material as or different from the tip blade may be arranged.

FIG. 2 is a plan view of the multi-demolition machine shown in FIG. FIG. 3 is an explanatory view showing a configuration of a shearing tool means of the multi-demolition machine shown in FIG. 1, a side view is a side view, and b is an explanatory view showing a shearing operation. FIG. 4 is an explanatory view for explaining the configuration of another embodiment of the multi-disassembly machine of the present invention, FIG. 4A is a side view, and FIG. 4B is an enlarged view of a main part.

As shown in FIGS. 1 to 3, the multi-demolition machine 10 of this embodiment includes a self-propelled vehicle 11, a turning stage 12 mounted on the vehicle 11, and a hydraulically operated boom arranged at the center of the stage 12. A scrap dismantling work pencher 14 attached to the tip of the boom 16 and a shearing tool means 20 mounted on the front portion of the vehicle 11 so as to be undulating and driveable to shear scrap are provided.

That is, the self-propelled vehicle 11 is equipped with a turning stage 12 driven by an engine output or electric power supplied from an external power source, and a hydraulic pressure generator 15 is mounted behind the stage 12. On the stage 12, a driving cabin 13 is provided on the left side of the front portion so as to face forward during traveling, and a hydraulically actuated boom 16 is pivotally supported in the central portion by a hydraulic actuator 17 or the like so as to be undulating. The boom 16 has a pencher 14 for dismantling work at its tip. The boom 16 is folded when the vehicle 11 is transported by a trailer truck or the like.

The dismantling work pencher 14 was handed over to the shearing tool means 20 in a state where the scrap object was grasped by the opening / closing operation, held the scrap object when sheared by the shearing tool means 20, or sandwiched by the shearing tool means 20. Various dismantling operations such as sandwiching a thin plate portion of a scrap object with a cutting blade of a pencher 14, grasping and tearing a peripheral part of a scrap object, and removing the scrap object can be performed.

Further, a support shaft 21 for horizontally supporting the rear end portion of the shearing tool means 20 is attached to the front portion of the vehicle 11 by a support shaft holding member 18. The undulating operation of the shearing tool means 20 is performed by a hydraulic actuator 19 provided so as to project forward from the vehicle 11. The tip of the telescopic hydraulic actuator 19 is attached to a force point 22 that receives the force of the hydraulic actuator 19 at a height lower than the support shaft 21 at the rear end of the shearing tool means 20, and the rear end is a vehicle. By being attached to 11, the tip of the shearing tool means 20 is lifted around the support shaft 21 as a fulcrum when the hydraulic actuator 19 is extended, and is lowered when the hydraulic actuator 19 is contracted.

In addition to being able to undulate, the shearing tool means 20 may preferably rotate around a longitudinal axis. That is, a rotation motor may be provided at the rear end portion provided with the support shaft 21 and the force point 22, and the tip portion may be rotated around the axis of the rotation motor.

Due to such a configuration, when shearing by the first jaw portion 23 and the second jaw portion 24 at the tip of the shearing tool means 20, the first jaw portion 23 and the second jaw portion 23 and the second jaw are set at a desired angle with the support shaft 21 as a fulcrum. Shearing can be performed after aligning the openings of the portions 24. Further, when the pencher 14 is used for tearing, the first jaw portion 23 and the second jaw portion 24 are sandwiched between the first jaw portion 23 and the second jaw portion 24, and the tip portion is raised and lowered in the vertical direction to be cut apart. By tearing the 2 jaw portion 24 in the direction toward the rotation shaft 26, the first jaw portion 23 and the second jaw portion 24 cannot be loosened and a good tearing operation can be performed.

The shearing tool means 20 of this embodiment is rotatable from a position 20 ° below the horizontal direction to a position 70 ° above the horizontal direction. As a result, the opening position and opening angle of the first jaw portion 23 and the second jaw portion 24 can be adjusted according to the type and size of the scrap object, the operation of the dismantling work pencher 14, and the like. In addition, it is also possible to operate the shearing tool means 20 itself so as to press it against the scrap object.

That is, it is also possible to cut the scrap by sandwiching it between the shearing tool means 20 and the ground. In this case, it may be pressed below the lower second jaw portion 24, and if the shearing tool means 20 is rotatable around the longitudinal axis, it may be rotated by 180 ° to the first jaw portion 23 and The second jaw portion 24 may be torn upward with the pencher 14 so as to be pressed against the ground with the opening direction facing down, or rotated by 90 ° to form the first jaw portion 23 and the second jaw portion. The scrap may be firmly pressed against the ground in a large area and torn upward with the pencil 14.

The specific configuration of the shearing tool means 20 includes a first jaw portion 23 and a second jaw portion 24, which are equipped with relative rotation between an open position and a closed position to shear scrap with a shear blade, and a first jaw portion 24. 1 The first hydraulic drive means 25 as a hydraulic drive means for rotating the jaw portion is provided. Each rear end of the pair of tip tapered blades 31b of the first jaw portion 23 is bent at an obtuse angle with respect to each mounting portion to provide a distance from each other over each of the subsequent first shear blades 33. A pair of tapered blades 32 arranged in the separating direction are arranged. A taper blade receiving blade 37 is provided at a position facing the second jaw portion 24 of the taper blade 32.

A pair of tapered blades 32, a pair of first shearing blades 33, a pair of second shearing blades 34, a pair of tapered blade receiving blades 37 of grooves 35 facing them, a pair of first shearing blade receiving blades 38, Since the pair of second shear blade receiving blades 39 are composed of rectangular interchangeable blades and four longitudinal sides as shear blades, individual mounting bolts (not shown) are removed. By replacing and mounting the individual shear blades, the life of the individual shear blades can be quadrupled.

As for the movement of the first jaw portion 23 and the second jaw portion 24, as shown in FIG. 3b, the extension of the first hydraulic drive means 25 causes the first jaw portion 23 and the second jaw portion 24 in the open state to move. It is gradually closed around the rotating shaft 26. In this case, the first jaw portion 23 invades the groove portion 35 of the second jaw portion 24 so that the edge surface 31a at the tip of the tip blade 31 of the first jaw portion 23 presses in a substantially vertical direction. Even for a high-strength scrap object, the edge surface 31a at the tip of the tip blade 31 easily penetrates along the width receiving blade 36a of the tip blade receiving blade 36, and a drilling hole is formed.

Due to the further extension of the first hydraulic drive means 25, the drilling hole having the size of the edge surface 31a gradually widens as the tip taper blade 31b invades the tip taper blade receiving blade 36b. A through hole is cut open by shearing between the first shearing blade 33 and the first shearing blade receiving blade 38, which are passed in parallel on the rotation shaft 26 side, while being sheared more widely by the subsequent tapered blade receiving blade 37 of the tapered blade 32. Therefore, even a high-strength scrap object is satisfactorily sheared by shearing between the second shearing blade 34 and the second shearing blade receiving blade 39.

In this embodiment, the first jaw portion 23 is driven by the first hydraulic drive means 25, but the second jaw portion 24 is made rotatable by the rotation shaft 26, and the second jaw portion 24 is made rotatable. May be rotated by the second hydraulic drive means. This makes it possible to adjust the second jaw portion 24 so that the tips of the first jaw portions 23 are substantially at right angles according to the thickness of the scrap object.

More specifically, the tip portion of the first jaw portion 23 is detachably attached to the tip portion of the first jaw portion 23, and the tip of the tip blade 31 has a blade width smaller than the thickness of the first jaw portion 23. The edge surface 31a that can come into contact with the object to be sheared is provided. The longitudinal side of the edge surface 31a in the width direction is arranged to face the width receiving blade 36a of the tip receiving blade 36 of the second jaw portion 24, and the edge surface 31a is formed by shearing between these width sides. To.

A pair of tip taper blades 31b are arranged on both sides of the edge surface 31a so that the blade width is continuously increased toward the rear end, and the outer ridges of these pair of tip taper blades 31b are blades. When the first jaw portion 23 and the second jaw portion 24 rotate and intersect with each other, the pair of tip taper blades 31b and the tip taper blade receiving blade 36b are rubbed against each other to shear the object to be sheared. .. Since a strong force is applied to the tip blade 31, a thick portion 31c is arranged from the edge surface 31a at the tip thereof so that the outside in the rotation direction is reinforced to be thicker than the inside. Therefore, the life can be extended.

Further, as shown in FIG. 4a, the multi-demolition machine 60 of another embodiment has the same configuration because the shear tool means 20 of the multi-demolition machine of FIG. 1 is changed to the shear tool means 40. Have the same code. That is, also in the construction tool means 40 of this embodiment, a support shaft 41 that horizontally supports the rear end portion of the shearing tool means 40 is attached to the front portion of the vehicle 11 by the support shaft holding member 18.

The undulating operation of the shearing tool means 40 is performed by a hydraulic actuator 19 provided so as to project forward from the vehicle 11. The tip of the hydraulic actuator 19 that is expanded and contracted is attached to the force point 42 at a height lower than the support shaft 41 of the rear end of the shearing tool means 40, and the rear end is attached to the vehicle 11. When the hydraulic actuator 19 extends, the tip of the shearing tool means 40 is lifted around the support shaft 41 which is a fulcrum, and when the hydraulic actuator 19 is contracted, it is lowered.

As a shearing blade of the first jaw portion 43 rotated about the rotation shaft 46 by the first hydraulic drive means 45, it has the same maximum width as the thickness of the first jaw portion 43 and has a tip with respect to the scrap to be sheared. A tip blade 51 into which the tip blade 51 penetrates, a pair of first shear blades 53 bent at an oblique angle with respect to the penetration direction of the tip blade 51 and arranged on both sides of the first jaw portion, and the first shear blade 53. A pair of second shear blades 54, which are bent at an blunt angle with respect to the mounting portion and are arranged on both sides of the first jaw portion 43, are provided.

As the shearing blade of the second jaw portion 44, all of the tip blade 51 and the pair of the first shearing blades 53 and a part of each of the pair of the second shearing blades 54 are used when moving relative to the first jaw portion 43. A groove portion (not shown) that allows passage, and a tip blade receiving blade 56 arranged on the inner wall surface of the groove portion in a region other than the region through which the first shear blade 53 passes so as to surround the outer peripheral surface of the passing tip blade 51. , A region through which both outer peripheral surfaces of the pair of first shear blade receiving blades 58 and the second shear blade 54, which are respectively arranged along the inner wall surface of the groove portion, pass through the outer peripheral surfaces of the first shear blade 53. A pair of second shear blade receiving blades 59, which are arranged along the inner wall surface of the groove portion of the above, are provided.

As described above, since the multi-demolition machines 10 and 60 of this embodiment are equipped with the shearing tool means 20 and 40 on the front or rear of the self-propelled vehicle 11 so as to be undulating and driveable, they are long at the demolition work site. Steel frames such as I-shaped steel and thick and long scraps are also finely picked up with the demolition work pencher 14 and lifted with the shearing blades of the first jaw portions 23 and 43 and the second jaw portions 24 and 44 of the shearing tool means 20 and 40. Since it can be cut, the cut steel material can be directly transported from the site to a steel manufacturer or the like. Therefore, the multi-demolition machines 10 and 60 of the embodiment can be operated like a mobile cutting factory.

Multi demolition machine according to the invention described in claim 3, outside the relative rotation direction of the first jaw portion from the small face of the cutting edge blade according to claim 2, the small surface of the cutting edge blade It is characterized in that the first jaw portion is reinforced as compared with the inside in the relative rotation direction .

In the multi-disassembly machine according to the invention according to claim 3, the first jaw portion rotates with respect to the second jaw portion from the edge surface of the tip of the cutting edge blade of the tip blade according to claim 2. It is characterized in that a thick portion reinforced with a wall thickness on the outer side in the direction of rotation intersecting with the inner side is arranged .

As for the movement of the first jaw portion 23 and the second jaw portion 24, as shown in FIG. 3b, the extension of the first hydraulic drive means 25 causes the first jaw portion 23 and the second jaw portion 24 in the open state to move. It is gradually closed around the rotating shaft 26. The tip blade 31 includes a cutting edge blade 31A arranged at the tip portion and a taper blade 32 that follows the cutting edge blade 31A. In this case, the first jaw portion 23 penetrates into the groove portion 35 of the second jaw portion 24 so that the edge surface 31a of the cutting edge blade 31A at the tip of the tip blade 31 of the first jaw portion 23 presses in a substantially vertical direction. Therefore, even for a high-strength scrap object, the edge surface 31a of the cutting edge blade 31A at the tip of the tip blade 31 easily penetrates along the width receiving blade 36a of the tip blade receiving blade 36, and a drilling hole is formed. Is formed.

Due to the further extension of the first hydraulic drive means 25, as the tip taper blade 31b of the cutting edge blade 31A of the tip blade 31 invades the tip taper blade receiving blade 36b, a drilling hole having a size of the edge surface 31a gradually becomes formed. The first shearing blade 33 and the first shearing blade receiving blade 38 passed in parallel on the rotation shaft 26 side while being further widely sheared by the tapered blade receiving blade 37 of the tapered blade 32 of the tip blade 31 that continues to be widened. Through holes are cut open by shearing, and even high-strength scrap objects are satisfactorily sheared by shearing between the second shearing blade 34 and the second shearing blade receiving blade 39.
