Description

multi-disassembler

The present invention relates to a novel multi-dismantling machine suitable for dismantling various damaged objects at various sites, such as, for example, waste automobiles, building waste, and pipe waste, and the like.

Although it is an old story now, the scrap dismantling work of scrap vehicles is to unload the scrap car in bulk one by one with a crane, transport it by a transport vehicle, and cut it to an appropriate size using a cutting torch, etc., at the workshop of a scrap factory, or engine The parts were being separated.

In response to such a situation, the present inventor is equipped with a pair of left and right working arms that can be opened and closed by power on the front or rear part of a self-propelled vehicle having a hydraulically operated boom having an opening and closing pencher at the tip so that it can swing and undulate, and this operation A pair of opposing cups for holding the scrap object rotatably from both sides to the arm, and a pair of breaking tools for crushing or breaking the scrap object by forcing it from both sides have already been proposed. There is (for example, refer patent document 1). The efficiency of the scrap dismantling operation was dramatically improved by the proposed dismantling machine or other improved dismantling machines following it, and the fractional collection of scrap by material was also made possible with high efficiency.

In addition, in recent years, not only discarded automobiles, but also various other scrap objects, for example, household appliances such as refrigerators and washing machines, construction waste such as reinforcing bars and window sashes, or waste piping such as water supply pipes and drain pipes, etc. It was impossible to process them all, and various scrap objects were accumulated in various places, and it was a situation waiting for dismantling.

In the conventional dismantling machine, without directly withdrawing the electric motor or compressor inside them by the opening/closing work pen point of the tip of the hydraulically operated boom, dismantling by separate manual operation or inevitably disposing of it as a whole without separation, etc. was performed. .

Under this circumstance, the present inventor has proposed a multi-purpose scrap dismantling machine capable of efficiently performing the classification and dismantling of various scrap objects, including scrap cars, by expanding the handling range of the fractional collection of scrap objects in terms of dimensions and strength (e.g. For example, refer to patent document 2).

In addition, the present inventor is a multi-dismantling machine suitable not only for dismantling automobile scraps, but also for fractional dismantling of building waste, and a pair of left and right working arms capable of undulating driving and opening/closing driving mounted on the front or rear part of the vehicle. A dismantling machine equipped with cutting scissors for cutting a scrap object at a position near the pivoting point of the arm has already been proposed (see, for example, Patent Document 3).

Japanese Patent Publication No. 3-78460 Japanese Patent Publication No. 3101717 Japanese Patent No. 4737751

Moreover, in recent years, the energy of recycling use of resources is increasing, and it is required to separate and collect waste materials as reusable raw materials rather than landfilling and disposing of waste materials, such as waste automobiles, as well as building waste and piping waste. For example, in the dismantling of buildings made of reinforced concrete, the distribution lines surrounding each section of the interior are copper resources, window sashes and partition panel frames are aluminum resources, and the steel frame itself, including railings and fire doors, is iron resources. can be reused as

However, in the conventional cutting shears as described above, when transporting high-strength aluminum or high-strength steel frame from a dismantling site, in order to be mounted on a transport vehicle such as a truck, it may not be cut to an appropriate size.

In the present invention, there is provided a hydraulically operated boom mounted on a self-propelled vehicle so as to be able to turn and undulate, a pencher for scrap dismantling operation that is opened and closed by remote operation attached to the tip of the boom, and the front or rear portion of the vehicle is undulating. It is a multi dismantling machine which is drivably mounted and provided with shearing tool means capable of shearing a scrap object.

As a supporting structure of the shearing tool means of the present invention, it is sufficient if it is mounted so as to be able to undulate on the front or rear of the vehicle and capable of shearing the scrap object. What is necessary is just to provide the point as a rotation center of undulation drive, and the power point which receives the force of the hydraulic actuator which expands and contracts at the height position lower than this point in order to make undulation drive possible. Thereby, when the hydraulic actuator is extended, the tip of the shearing tool means rises centering on the point as an action point. As a hydraulic actuator, since extension rather than contraction can give a tremendous force, it exhibits the advantage of being able to perform shearing work satisfactorily.

The tip structure of the shearing tool means of the present invention includes first and second jaws for shearing a scrap object with a shear blade mounted relatively rotatably between an open position and a closed position, and these first and/or second jaws. What is necessary is just to be provided with the hydraulic drive means which rotates a part. When opening and closing both the first jaw and the second jaw, respectively, hydraulic drive means must be provided, so that the shear tool means itself becomes heavy. For this reason, Preferably, it is set as either the 1st jaw part or the 2nd jaw part, More preferably, it is set as the mechanism which opens and closes only the 1st jaw part provided with the front-end|tip blade.

As a specific structure of the shearing tool means of the present invention, a shearing blade of a first jaw, having a maximum width equal to the thickness of the first jaw, through which the tip penetrates into the scrap to be sheared; A pair of first shearing blades respectively bent in an obtuse angle with respect to the first jaw and disposed on both surfaces of the first jaw, and a pair of first shearing blades bent in an obtuse angle with respect to the first shearing blade attachment portion and disposed on both surfaces of the first jaw, respectively 2 A shear blade is provided.

In addition, as a shear blade of the second jaw, a groove portion for traversably accommodating the tip blade and all of the pair of first shear blades and a part of each of the pair of second shear blades during relative movement with the first jaw; A leading edge receiving blade disposed on the inner wall surface of the groove portion other than through which the first shearing blade passes so as to surround the outer peripheral surface of the leading edge, and along the inner wall surface of the groove portion in the region through which both outer peripheral surfaces of the first shearing blade pass. A pair of first shearing blade receiving blades respectively disposed and a pair of second shearing blade receiving blades respectively disposed along the inner wall surface of the groove portion in a region through which both outer peripheral surfaces of the second shearing blade pass are provided.

With the first jaw and the second jaw, the tip of the tip of the tip of the first jaw comes into contact with the shearing object at the start of shearing, and the pressure of the hydraulic drive system can be concentrated on the tip, so that the high-strength scrap object is sheared. It can also be done easily. That is, when only the tip of the tip blade of the first jaw part contacts the high-strength scrap object, the hydraulic pressure can be concentrated on this part, and the drilling hole is formed. It can be well sheared by the first shearing blade and the first shearing blade receiving blade continuing to the formed drilling hole.

In addition, since the tip of the tip blade of the first jaw is pressed in a substantially vertical direction with respect to the scrap to be sheared, the tip does not come off from the pressing position, and the hydraulic pressure can be satisfactorily concentrated on the pressing position. That is, when cutting a high-strength scrap object, the tip of the tip of the first jaw is pressed to the cutting point, and the pressure is concentrated on the tip, so that the tip does not come off from the pressing point, and the drilling hole is easily formed by the tip. Then, the high-strength scrap object is sheared by the first and second shearing blades behind the later leading edge. If the second jaw can also be opened and closed, there is an advantage of adjusting the opening and closing state according to the thickness of the scrap object.

In the shearing tool means of the present invention, it is preferable that the shearing blade of the first jaw as a tip blade has a maximum width equal to the thickness of the first jaw, and that the tip penetrates the object to be sheared. In a preferred embodiment, the tip blade is disposed at the tip of the first jaw and has a small spherical surface having a blade width smaller than the thickness of the first jaw first contacting an object to be sheared, and is disposed on both sides of the small spherical surface and the blade width is continuously increased toward the rear end. A pair of blades having a pair of tip tapered blades, and a pair of blades arranged in an obtuse angle with respect to each attachment portion of the trailing end of the tip tapered blade and arranged in a direction to widen the distance from each other across each of the first shear blades of tapered blades.

Thereby, the pressure of the hydraulic drive system is favorably generated as shear stress on the small spherical surface of the width smaller than the thickness of the first jaw and the width receiving blade, and even the shearing object of the high-strength scrap object easily penetrates the tip of the tip blade. As a result, a perforation hole is formed. For this reason, after the small spherical surface of the tip blade of the first jaw portion first contacts the shearing object and drilling the high-strength scrap object, a pair of tip tapered blades widen the drilled hole, and further cutting with a pair of tapered blades It is widened to the width of the first shear blade.

In this way, by gradually driving the first jaw part, it can be broken while forming a large number of drilling holes on the small spherical surface of the tip blade. , a high-strength scrap object can be sheared by the first shearing blade and the second shearing blade.

In addition, the shah angle, which is the opening angle of the opposing blades of the shear blade of the present invention, reduces the force required for cutting by giving an angle to the blade of one side (usually the blade of the movable side) in the straight blade, A clean cross section is obtained by continuously cutting out from one direction. If the sharp angle is increased, the “maximum shear force” is reduced and the power of the shear (cutter) can be made small. In other words, the quality and quality of shear products are deteriorated.

Further, depending on the size of the gap (clearance) between the opposing blades of the shear blade of the present invention, the quality of the cross section, the required shear force, the lateral force, and the like change. In shearing machines, the standard value of the clearance value is often indicated by the thickness of the cut plate or the classification of the steel type to a certain extent. Select the optimum clearance. For example, for a thickness of 20 mm, a clearance of 20% of the thickness is taken.

In addition, the tip blade of the first jaw part contacts the small spherical surface with a strong pressure to the shearing target, concentrates the pressure of the hydraulic drive system on the tip to shear the shearing target, and a pair of tip formed from the small spherical surface to both sides. The hole drilled by the tapered blade is widened, and it is widened to the width of the first shearing blade while cutting with a pair of continuous tapered blades. Therefore, since a strong force is applied to the tip blade, when the outer side in the rotational direction from the small spherical surface of the tip is reinforced compared to the inner side, the life can be prolonged. As reinforcement, the outer side may be thicker than the inner side, or the same material as the tip blade or a reinforcing material of a different material may be disposed.

An arranged hydraulically operated boom 16, a scraper 14 for scrap dismantling attached to the tip of the boom 16, and shearing tool means mounted undulatingly drivably on the front of the vehicle 11 and shearing the scrap (20) is 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 generating device 15 is mounted on the rear of the stage 12 . On the stage 12, the driving cabin 13 is installed on the left side of the front part so as to be in the forward direction when traveling, and the hydraulically operated boom 16 is pivotally supported by a hydraulic actuator 17, etc. The boom 16 has a pen point 14 for dismantling work at its tip. This boom 16 is folded when conveying the vehicle 11 by a trailer truck or the like.

The penser 14 for dismantling work is handed over to the shearing tool means 20 in a state of holding the scrap object by opening/closing operation, or holding the scrap object when shearing with the shearing tool means 20, or the shearing tool means 20 Various dismantling operations such as cutting the thin plate portion of the scrap object sandwiched by the stylus 14 with the cutting blade of the pencher 14, gripping and tearing the parts around the scrap object, or separating can be performed.

In addition, a support shaft 21 for supporting the rear end of the front end tool means 20 in the horizontal direction is attached to the front portion of the vehicle 11 by a support shaft holding member 18 . The undulating operation of this shear tool means 20 is performed by a hydraulic actuator 19 provided to project forward from the vehicle 11 . The front end of the extensible hydraulic actuator 19 is attached to the power point 22 receiving the force of the hydraulic actuator 19 at a height lower than the support shaft 21 of the rear end of the front end tool means 20, and the rear end is attached to the vehicle ( 11), when the hydraulic actuator 19 extends, the tip of the shear tool means 20 rises centering on the support shaft 21 serving as a fulcrum, and descends when the hydraulic actuator 19 expands.

In addition to being able to undulate, the shear tool means 20 may preferably be rotated about its longitudinal axis. That is, a rotation motor may be provided in the rear end provided with the support shaft 21 and the force point 22, and a front-end|tip part may be made to rotate around the axial center of a rotation motor.

Due to such a configuration, when shearing by the first and second jaws 23 and 24 of the distal end of the shearing tool means 20, the first jaw 23 at a desired angle with the support shaft 21 as a fulcrum. ) and the opening of the second jaw part 24 can be sheared after matching. In addition, when performing the tearing by the pincher 14, the first jaw portion 23 and the second jaw portion are pinched by the first jaw portion 23 and the second jaw portion 24, and then the tip portion is undulated in the vertical direction to determine the tearing direction. By pulling in the direction toward the rotational shaft 26 of the 24, a good tearing operation can be performed so that the pinching of the first jaw part 23 and the second jaw part 24 is not loosened.

The shear tool means 20 of the present embodiment is rotatable from a downward position of 20° from the horizontal direction to a 70° upward position from the horizontal direction. Thereby, it becomes possible to adjust the opening positions and opening angles of the first and second jaws 23 and 24 according to the type and size of the scrap object, the operation of the penser 14 for dismantling, and the like. It is also possible to operate the shearing tool means 20 itself to press the scrap object.

That is, it is also possible to tear off the scrap between the shearing tool means 20 and the ground. In this case, it may be pressed from the lower side of the second jaw portion 24, which is the lower side, or if the shear tool means 20 is rotatable about the longitudinal axis, it is rotated 180° to the first jaw portion 23 and the second jaw portion 24. You may tear it upward with the pen point 14 by pressing it against the ground with the opening direction of You may tear it off by pressing it upwards with the pliers 14.

The specific configuration of the shearing tool means 20 includes first and second jaws 23 and 24 that are mounted to be rotated relatively between an open position and a closed position and shear the scrap with a shearing blade, and the first jaws are rotated. and first hydraulic drive means 25 as hydraulic drive means. At the rear end of each of the pair of tip tapered blades 31b of the first jaw portion 23, each of the attachment portions is bent in an obtuse shape to widen the distance from each other over each of the subsequent first shear blades 33. A pair of tapered blades 32 arranged in the direction are arranged. A tapered blade receiving blade 37 is provided at a position opposite to the second jaw portion 24 of the tapered blade 32 .

In addition, a pair of tapered blades 32, a pair of first shearing blades 33, a pair of second shearing blades 34, and a pair of tapered accommodating blades 37 of a groove part 35 facing them; As for the pair of first shearing blade receiving blades 38 and the pair of second shearing blade receiving blades 39, it is composed of a rectangular parallelepiped-shaped replaceable blade, and is configured with four length sides as shear blades, so each attachment By removing the bolts (not shown in the drawing) and replacing and mounting each shear blade, it becomes possible to quadruple the life of each shear blade.

As a movement of the 1st jaw part 23 and the 2nd jaw part 24, as shown in FIG. 3B, the 1st jaw part 23 and the 1st jaw part 23 in an open state and the 2 The jaws 24 are gradually closed around the rotation shaft 26 . The tip blade 31 is composed of a tip blade 31A disposed at the tip portion and a tapered blade 32 following it. In this case, the first jaw portion 23 is the second jaw portion 24 so that the small spherical surface 31a of the tip blade 31A at the tip of the tip blade 31 of the first jaw portion 23 is pressed in the substantially vertical direction. It penetrates into the groove part (35). For this reason, even if it is a high-strength scrap object, the small spherical surface 31a of the tip blade 31A of the tip end of the tip blade 31 penetrates along the width reception blade 36a of the tip edge receiving blade 36, and the drilling hole this is formed

Due to the extension of the additional first hydraulic drive means 25, the tip tapered blade 31b of the tip blade 31A of the tip blade 31 penetrates into the tip tapered blade receiving blade 36b, and the small spherical surface 31a ), the drilling hole of the size is gradually widened, and as it is sheared more widely by the tapered blade 32 and the tapered receiving blade 37 of the leading edge 31, the first shearing in parallel on the rotational shaft 26 side The through-hole is cut by the front end of the blade 33 and the first shearing blade receiving blade 38, and even if it is a high-strength scrap object by the front end of the second shearing blade 34 and the second shearing blade receiving blade 39 Shears well.

In the present 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 this second jaw portion ( 24) may be rotated by the second hydraulic drive means. Thereby, it becomes possible to adjust the 2nd jaw part 24 so that the front-end|tip of the 1st jaw part 23 may become substantially right-angled according to the thickness of a scrap object.

In more detail, the tip of the first jaw part 23 is detachably attached to the tip of the first jaw part 23, and the tip of the tip blade 31 has a blade width smaller than the thickness of the first jaw part 23, It has a small spherical surface 31a which can be contacted with respect to a shearing object. The longitudinal side of the small spherical surface 31a in the width direction is disposed to face the width receiving blade 36a of the tip receiving blade 36 of the second jaw portion 24, and shearing the small spherical surface 31a with these width sides causes the small spherical surface 31a this is swept away

On both sides of the small spherical surface 31a, a pair of tip tapered blades 31b are arranged such that the blade width is continuously increased as they face the rear end, and the outer ridge of the pair of tip tapered blades 31b becomes the blade portion, When the first jaw part 23 and the second jaw part 24 rotate and intersect, the pair of tip tapered blades 31b and the tip tapered edge receiving blade 36b rub against each other, and the shearing object is sheared. In addition, since a strong force is applied to the tip blade 31, a thick portion 31c whose outer side in the rotational direction is thicker than the inner side is disposed from the small spherical surface 31a of the tip. For this reason, life can be lengthened.

In addition, as shown in FIG. 4A, the multi-dismantling machine 60 of another embodiment has a configuration in which the front-end tool means 20 of the multi-disassembler of FIG. 1 is changed to the front-end tool means 40, so that of the same configuration The same code|symbol is attached|subjected to the point.
