JP, 2008-88642, A

  Although a self-propelled water sprinkler as shown by patent document 1 is made applicable also to dismantling of a high-rise building RC, the place where a high-rise building RC actually exists is often an urban area. In an urban area, the site itself of the high-rise building RC is narrow, and the road condition leading to the site is not always good. In other words, if a work support machine as shown in Patent Document 1 is used in an urban area, the work support machine and the work machine can not be replaced appropriately, so the work support machine occupies a constant space at the work site CS constantly. As a result, the number and size of working machines that perform dismantling operations themselves placed in the site will be limited. Moreover, the work support machine having such a configuration is not always required at the work site CS. Therefore, by using the work support machine as shown in Patent Document 1, it is not possible to effectively support the work as a result. For example, it may be difficult to quickly disassemble the high-rise building RC. .

  Therefore, the present invention has been made to solve the above-mentioned problems and the like, and it is an object of the present invention to provide a work attachment and a work machine capable of effective work support even when the size of a site is limited. Do.

  The present invention is a work attachment attached to a swingable arm of a work machine, the equipment mounting part supporting a support equipment for supporting work, and an expandable support column supporting the equipment mounting part And a connection portion connected to the support portion and detachably connected to the arm body, and power of the arm body is transmitted to the support portion via the connection portion to extend and contract the support portion. Solves the problems described above.

  That is, in the present invention, an equipment mounting portion for supporting the support equipment, an expandable support portion for supporting the equipment mounting portion, and a connection portion connected to the support portion and detachably connected to the arm body The configuration provided is a work attachment. For this reason, the work itself can be performed by attaching a work attachment capable of performing the work itself to the work machine as necessary. And this work attachment can be attached to the work machine only when necessary. That is, space saving can be realized by sharing the working machine main body. Moreover, since the work attachment is attached to the arm body, the equipment mounting portion can be raised to a high position even if the work machine is small. For this reason, for example, if the support equipment has a water sprinkler (water sprinkler), dust can be effectively suppressed even if the high-rise building RC is disassembled or the like. The support equipment is not limited to the water sprinkling means, and may be another means as long as the work support equipment. In addition, the work here may include not only dismantling work but also work such as construction work, fire fighting and disasters.

  In addition, even if the state of the arm body and the support section changes, when the equipment mounting unit is controlled to be kept horizontal, it is possible to stably execute the work support by the support equipment. Become. At the same time, the possibility of dropout of support equipment itself can be reduced.

  In addition, when the said support apparatus has a water sprinkling means as mentioned above, work assistance can be performed by suppressing generation | occurrence | production of the dust from a work location by a water sprinkling means.

  In addition, when the said support apparatus has an imaging means, work assistance can be performed by imaging a work location by an imaging means. For example, even if the working condition of the working place can not be directly seen from the working machine, the working condition can be confirmed by a monitor wirelessly connected to the imaging means provided in the working machine.

  In addition, when the said support apparatus has an illumination means, work assistance can be performed by making the work location bright with an illumination means. For example, it is possible to check the work status of the work location even if the situation is not clearly seen in a dark situation.

  In the case where the support equipment has a shatterproof member including a sheet member capable of blocking the work piece generated at the work location and a frame member for keeping the sheet member flat, the shatterproof member serves as the work location By arranging in close proximity to each other, it is possible to prevent the work pieces generated at the work place from being scattered widely. Moreover, since the sheet member is kept flat by the frame member, scattering of the work piece can be effectively prevented while reducing the weight of the scatter prevention member, and even if the angle range generated by the work piece is wide. It becomes.

  The support equipment has a plurality of the same types, and the support equipment of the same type is supported at equal intervals in the circumferential direction on the equipment mounting portion, and the entire circumferential direction on the equipment mounting portion is by the support equipment. When the support equipment is made rotatable so as to be the target of the work support, the work support can be equally performed in all circumferential directions without being influenced by the orientation of the equipment mounting portion.

  In addition, when the said support apparatus is remotely operated by radio | wireless, it becomes possible to expand the positional freedom degree of an equipment mounting part compared with the case of wired operation. At the same time, it will be easier to support support equipment.

In the work machine to which any one of the work attachments described above is attached , when the other work attachment is attachable by removing the work attachment, the work attachment uses the other work attachment. Work can proceed.

  According to the present invention, effective work support can be performed even if the size of the site is limited.

  Hereinafter, an example of the first embodiment of the present invention will be described in detail with reference to the drawings.

  First, the configuration of the backhoe (working machine) 100 according to the present embodiment will be described with reference to FIG. Note that this backhoe 100 can be widely used for dismantling work of buildings regardless of the high-rise building RC.

  The backhoe 100 includes a vehicle body 120, an arm body 127, and a work attachment 140, as shown in FIG. The vehicle body 120 includes a crawler-type traveling body 122, a turning mechanism 124, and a turning body 126. That is, the swing body 126 is rotatable relative to the traveling body 122 by the swing mechanism 124. The revolving structure 126 is provided with a cab 126A. The operator's cab 126A has a sealable configuration, can block rain and wind, and can be temperature controlled by an air conditioner. That is, the driver can operate the backhoe 100 stably without being influenced by the weather (not limited to this, the backhoe may be operated unmanned). An arm body 127 which is pivotable up and down is attached to the revolving body 126. The backhoe main body has a form in which the work attachment 140 is removed, and includes a vehicle body 120 and an arm body 127.

  The arm body 127 includes a boom 128 attached to the rotating body 126 and an arm 132 attached to the tip of the boom 128, as shown in FIG. The arm 132 is pivotable by the cylinder mechanism 130. That is, the arm body 127 can be swung by the hydraulic pressure supplied from the vehicle body 120. A work attachment 140 is attached to the tip of the arm 132. The work attachment 140 is pivotable by the cylinder mechanism 134 via the link mechanism 136. That is, the work attachment 140 is attached to the swingable arm 127 of the backhoe 100, and is movable in the vertical direction and in the front-rear and left-right directions with respect to the vehicle body 120 of the backhoe 100. The backhoe 100 can be attached with other work attachments such as a grapple, a cutter, and a crusher by removing the work attachment 140.

  Next, the work attachment 140 will be schematically described with reference to FIGS.

  The work attachment 140 is, as shown in FIG. 1, an equipment mounting portion 150 on which a sprinkler (supporting equipment for supporting the work, and a sprinkler) 152 is supported (arranged), and the equipment mounting portion 150 via a support mechanism 148. And a connectable portion 142 connected to the support portion 144 and detachably connected to the arm body 127. Although not shown, the hydraulic pressure, which is the power of the arm 127, is transmitted to the support 144 through the connection 142 to extend and contract the support 144.

  Next, each component of the work attachment 140 will be described in detail with reference to FIGS. 2 and 3A to 3C.

  As shown in FIGS. 3A to 3C, the connection portion 142 includes a fixed portion 142A and a movable portion 142B fixed to the arm body 127, and an engaging portion 142C fixed to the support 144. Equipped with The fixing portion 142A is substantially L-shaped, and is fixed to the arm body 127 by the first connecting shaft 142AB and the second connecting shaft 142BB. Then, a first concave portion 142AA engaged with the engaging portion 142C is provided on the outside of the distal end portion of the fixing portion 142A. The movable portion 142B is substantially I-shaped, and is attached to the arm body 127 so as to be rotatable by the second connecting shaft 142BB. A second concave portion 142BA engaged with the engaging portion 142C is provided on the outer side of the distal end portion of the movable portion 142B in the direction opposite to the first concave portion 142AA. In the present embodiment, a spring (not shown) is engaged with the movable portion 142B so that a force acts on the second recess 142BA in a direction away from the first recess 142AA (even if this spring is not provided). Good).

  On the other hand, the engagement portion 142C supports the first engagement shaft 142CA engaged with the first recess 142AA and the second engagement shaft 142CB engaged with the second recess 142BA to the outside. Therefore, in order to connect the connection portion 142, the following procedure is performed.

  First, as shown in FIG. 3A, the fixed portion 142A and the movable portion 142B are made to approach the engaging portion 142C. Then, in a state in which the arm body 127 is inclined and the first recess 142AA and the first engagement shaft 142CA are separated, the second recess 142BA is first engaged with the second engagement shaft 142CB. Then, the fixing portion 142A is pushed toward the engaging portion 142C, and as shown in FIG. 3B, the distance between the first recess 142AA and the second recess 142BA is reduced. Next, the first recess 142AA is inserted between the first engagement shaft 142CA and the second engagement shaft 142CB to reduce the distance from the first engagement shaft 142CA. Then, as shown in FIG. 3C, the first recess 142AA and the first engagement shaft 142CA are engaged. In addition, the removal of the connection part 142 can be implement | achieved by reversely performing the procedure performed at the time of said connection.

  Therefore, for example, by moving the arm body 127 relative to the state in which the work attachment 140 is disposed on the ground, detachment of the work attachment 140 at the connection portion 142 can be easily realized. Here, the load from above the work attachment 140 is supported by the first concave portion 142AA of the fixed portion 142A shown in FIGS. 3 (A), (B), and (C). Then, the lateral movement of the work attachment 140 is configured to be received by the second concave portion 142BA of the movable portion 142B. For this reason, when connected by the connection part 142, it is possible to support the work attachment 140 stably.

  As shown in FIGS. 4 (A) and 4 (B), in the support column 144, cylindrically shaped first support column 144A to sixth support column 144F having different cross-sectional outer diameters are fitted in an expandable and contractable direction O with each other. The configuration is For this reason, the supporting column 144 is relatively lightened while increasing the expansion ratio. A hydraulic cylinder (not shown) is disposed inside the sixth support column 144F, and the hydraulic cylinder is driven by the hydraulic pressure that is the power of the arm body 127 to control the amount of expansion and contraction of the support column 144 (for example, It becomes 2 to 3 m in length in the contracted state, and more than a dozen m in its expanded state). Reference numeral 146 denotes a hose reel, which is configured to wind up a water supply hose connected to a water sprinkler 152 supported by the equipment mounting unit 150 in accordance with the expansion and contraction of the support 144.

  The support mechanism 148 is disposed between the support portion 144 and the equipment mounting portion 150, as shown in FIGS. Then, in the support mechanism 148, (the upper surface of) the equipment mounting portion 150 remains horizontal even when the support post 144 is inclined from the vertical direction V (that is, even when the states of the arm body 127 and the support post 144 change). (That is, when the tilt state of the equipment loading unit 150 is recognized without control from the outside, it is controlled so as to automatically cancel the tilt state). Specifically, as shown in FIG. 5C, the support mechanism 148 includes an inclination sensor IS, a processing unit PS, and a drive mechanism DF. The inclination sensor IS is attached to the equipment mounting unit 150 and detects the inclination angle of the equipment mounting unit 150 from the horizontal direction. The processing unit PS is attached to the frame 148A of the support mechanism 148, processes the output of the inclination sensor IS, and outputs a signal for driving the drive mechanism DF so as to correct the inclination angle of the equipment mounting unit 150. The drive mechanism DF is attached to the frame 148A such that the inclination angle of the support 144 can be adjusted.

  5A and 5B show an example of a specific configuration of the support mechanism 148 which can adjust the inclination angle of the sixth support 144F in the axial direction. Here, the cylinder mechanism 148D is a part of the drive mechanism DF (that is, the adjustment of the inclination angle in the two axial directions is achieved by the configuration of the cylinder mechanism 148D shown in FIGS. 5A and 5B). Therefore, in the present embodiment, the inclination angle of the sixth support 144F in the direction of one axis can be adjusted, or in the direction of the two axes of the sixth support 144F. The angle of inclination of can be made adjustable). The sixth support portion 144F rotatably supports the frame 148A by a support shaft 148B. A cylinder mechanism 148D is connected to the frame 148A via an adjusting shaft 148C. The rod 148E, which is a movable member of the cylinder mechanism 148D, is rotatably supported by the sixth support 144F by the rod support shaft 144FA. Therefore, as shown in FIGS. 5A and 5B, it is possible to appropriately change the angle of the sixth support 144F with respect to the frame 148A by expanding and contracting the rod 148E by the output of the processing unit PS. is there. The power supply of the inclination sensor IS and the processing unit PS may be, for example, a rechargeable battery or the like, and may be exchangeably disposed inside the frame 148A. The power supply of the drive mechanism DF may have a similar configuration. Of course, if the drive mechanism DF includes the cylinder mechanism 148D, a hydraulic pressure that is also supplied to the arm body 127 may be used as the power (the drive mechanism DF may be configured using an electric motor). In addition, you may carry out remote control so that it may become possible to change not only this but the angle of an equipment mounting part and a support | pillar part suitably according to a condition. Alternatively, the angle between the equipment mounting portion and the support portion may be adjusted and fixed in advance so that the upper surface of the equipment mounting portion becomes horizontal when the length of the specific support portion or the inclined state is reached.

  The equipment mounting portion 150 has a plate shape as shown in FIG. 6 (B), and a plurality of water sprayers 152 are detachably mounted on the upper surface thereof and mounted. In addition, when the water sprinkler 152 is unnecessary, the water sprinkler 152 can be removed from the upper surface of the equipment mounting portion 150 (or together), and a light projector (illumination means) capable of changing the light projection direction It is possible to attach other supporting equipment such as a camera (imaging means) whose magnification can be changed. As shown in FIG. 6 (A), the water sprayer 152 is rotatable in the vertical direction and the horizontal direction in the direction of the water spray port 152A. The direction and opening / closing of each of the water spray ports 152A are remotely controlled by wireless by one transmitter (not shown) (that is, the sprinkler 152 is remotely controlled by wireless). The three sprinklers 152 are of the same type, and are supported at equal intervals in the circumferential direction on the equipment mounting portion 150 as shown in FIG. 6 (B). That is, they are disposed at every 120 degrees in the circumferential direction. And each water sprinkler 152 is made rotatable at least 120 degrees or more so that the entire circumferential direction on the equipment mounting portion 150 is the target of the work support by the water sprinkler 152 (in addition, it is not limited to this. The machines may vary in size, and the number of sprinklers may be two or four.

  Next, the operation of the present embodiment will be described.

  In the present embodiment, the equipment mounting unit 150 on which the water sprayer 152 for supporting the work is supported, the expandable support column 144 supporting the equipment installation unit 150, and the support column 144 are detachable from the arm 127. The work attachment 140 is configured to include the connection portion 142 to be connected. That is, in the present embodiment, for example, work is performed using a backhoe attached with a work attachment for performing the work itself. Then, in the middle of the work or at a part of the work, the work attachment for performing the work itself is removed from the backhoe. And it becomes possible to attach the above-mentioned work attachment 140 and perform watering etc. by backhoe 100 using the same backhoe main body to support work (the order of changing work attachments may be reversed, or It may be repeated).

  As described above, in the present embodiment, the work itself can be performed by attaching the work attachment capable of performing the work itself to the backhoe 100 as needed. The work attachment 140 can be attached to the backhoe 100 only when necessary. That is, space saving can be realized by sharing the backhoe main body. Moreover, since the work attachment 140 is attached to the arm body 127, the equipment mounting portion 150 can be elevated to a high position even if the backhoe 100 is small. For this reason, even if the high-rise building RC is disassembled or the like by the water sprinkler 152, the generation of dust from the work site can be effectively suppressed, and work support can be performed. Further, since the hydraulic pressure which is the power of the arm body 127 is used as the power of the support 144, it is not necessary to separately provide a power for expanding and contracting, and the configuration can be simplified. Furthermore, since the water sprinkler 152 supported by the equipment mounting unit 150 is detachable, it can be detached when the water sprinkler 152 is not used, and other supporting equipment such as a light projector and a camera can be attached and used.

  Further, in the present embodiment, even if the states of the arm body 127 and the support portion 144 change, the equipment mounting portion 150 is controlled to be horizontal. That is, the direction control of the actual sprinkling port 152A in consideration of the position of the object to be sprinkled can be performed independently of the arrangement position of the sprinkler 152. For this reason, it becomes possible to stably execute the work support by the water sprinkler 152 supported by the equipment mounting unit 150. At the same time, since the sprinkler 152 itself is not inclined, the possibility of dropout of the sprinkler 152 itself can be reduced. In addition, it is not limited to this, When the state of an arm body and a support | pillar part is specific conditions, the upper surface of the equipment mounting part may become horizontal. At that time, the sprinkler may be controlled under the specific condition. Or you may control a sprinkler instead of such specific conditions.

  Further, in the present embodiment, three of the same types of sprinklers 152 are supported by the equipment mounting unit 150. Then, the same type of water sprayers 152 are supported at equal intervals in the circumferential direction on the equipment mounting portion 150, and the water sprinkler 152 is provided such that the entire circumferential direction on the equipment mounting portion 150 becomes a target of work support by the water sprinklers 152. Is made rotatable. Therefore, the work support can be equally performed in the circumferential direction without being affected by the orientation of the equipment mounting unit 150.

  In addition, in the work site CS, for example, the high-rise building (reinforcing steel structure) RC is disassembled, and the generated concrete pieces CP are collected at one place to form the glared mountain MP. In many cases, a plurality of backhoes BH are attached to the mountain MP from different directions, and work is often performed to further crush concrete CP which can be reused. At this time, as shown in FIG. 7, the equipment mounting portion 150 is positioned by the backhoe 100 near the top of the mountain MP, and the water sprinkler 152 is disposed corresponding to the direction of each backhoe BH (FIG. 7). Then, the generation of dust can be effectively prevented by the dotted line). At this time, since the backhoe 100 is configured to include the expandable and contractible support 144 at the tip of the arm body 127, the working position of the other backhoe BH is not hindered. Moreover, it is possible to avoid the operator who sprinkling water to water the mountain MP itself ascend to the mountain MP, and of course, it is possible to avoid arranging the water sprayer on the mountain MP and changing its position, and the worker's safety and convenience Sex can also be secured securely.

  Not limited to this, one or more sprinklers may be supported by the equipment mounting unit. Alternatively, instead of a water sprayer, a light projector may be used. In this case, the work support can be performed by brightening the work place with the light projector. For example, it is possible to check the work status of the work location even if the situation is not clearly seen in a dark situation. Alternatively, it may be a camera. In that case, work support can be performed by imaging the work place with a camera. For example, even if it is not possible to directly view the work status of the work location from the backhoe BH, it becomes possible to check the work status with a monitor wirelessly connected to the imaging means provided on the work machine.

  Further, in the present embodiment, the water sprinkler 152 is remotely controlled by wireless. For this reason, it is possible to expand the degree of freedom in the position of the equipment mounting unit 150 as compared to the case of the wired operation. At the same time, the support of the water sprayer 152 is facilitated.

  Further, in the present embodiment, another work attachment is also attachable to the backhoe 100 to which the work attachment 140 is attached. For this reason, it becomes possible to advance work itself using other work attachments by this backhoe 100.

  That is, according to the present embodiment, effective work support is possible even if the size of the site is limited.

  Although the present invention has been described with the above embodiment, the present invention is not limited to the above embodiment. That is, it goes without saying that improvements and design changes can be made without departing from the scope of the present invention.

  For example, in 1st Embodiment, although the backhoe 100 was small and three water sprinklers 152 were used, this invention is not limited to this. For example, it may be as in the second embodiment shown in FIG. Note that, in FIG. 8, all schematic diagrams when various states of the arm body 227 and the work attachment 240 are changed are displayed as solid lines. In the second embodiment, as shown in FIG. 8, a larger backhoe 200 is used. Therefore, in combination with the length of the arm body 227, it is possible to elevate the equipment mounting portion, for example, from 20 to 30 m from the ground (9 floors or more in the case of an apartment). In the present embodiment, only one sprinkler 252 is attached to the equipment mounting portion. Moreover, although the arm body 227 is comprised from one boom and one arm also in this embodiment, the arm body may be comprised from several boom and several arm.

  Moreover, in the said embodiment, although the support | pillar part of the work attachment was comprised from six support | pillar parts, it is not limited to this. For example, the third embodiment shown in FIGS. 9A to 9C may be employed. In the third embodiment, the support portion 344 is formed of five support portions (344A to 344E), and the shape of the connection portion 342 is different from that of the first embodiment (note that FIGS. 9A to 9C). In (C), only the engaging portion 342C of the connecting portion 342 is shown). The number of support portions is not limited to five, and may be plural.

  In the first and second embodiments, the support equipment is mainly a water sprinkler, but the present invention is not limited to this. For example, it may be the fourth embodiment shown in FIG.

  In the fourth embodiment, as shown in FIG. 10, the support equipment makes the sheet member 452B and the sheet member 452B flat, which can block the fragments (workpieces) BP of the dismantling material generated at the work site (of the work of disassembly) And a frame member for holding the same. Specifically, the equipment mounting portion 450 of the work attachment 440 includes a winding mechanism (not shown) inside. The winding mechanism can raise and lower the hook 450A at the tip end by winding up the wire rope 450B (also by this, the vertical position of the anti-scattering member 452 can be adjusted). In the hook 450A, the shatterproof member 452 is supported (note that the equipment mounting portion may directly support the shatterproof member without the winding mechanism, the wire rope, the hook, and the like).

  The sheet member 452B of the scattering prevention member 452 is a curing sheet made of a tape such as polyethylene, for example. Therefore, the sheet member 452B can be well ventilated, not easily torn, and can secure a light and wide area. The frame member in FIG. 10 includes an upper frame body 452A, a lower frame body 452C, and a connecting rope 452D. As the upper frame body 452A and the lower frame body 452C, for example, a metal cylindrical pipe or the like used in the work site CS can be used. By firmly fixing all the upper sides of the sheet member 452B to the upper frame body 452A, the sheet member 452B can be spread. Further, by fixing a plurality of places (two ends in FIG. 10) of the sheet member 452B to the lower frame body 452C by the connecting rope 452D, the sheet member 452B becomes a weight, and the sheet member 452B is substantially vertical Can be kept flat.

  By this, for example, as shown in FIG. 10, it is assumed that the high-rise building RC is disassembled by the crusher CR which is a work attachment attached to another backhoe BH. At this time, by arranging the scattering prevention member 452 close to the work area by the crusher CR, it is possible to prevent the fragments BP of the dismantling material generated at the work area from being shielded by the scattering prevention member 452 and scattering widely. Is possible. Moreover, since the sheet member 452B is maintained flat by the frame member, the scattering prevention member 452 can be made lightweight, and the fragments BP of the disassembling material can be effectively produced even if the angular range in which the fragments BP of the disassembling material are generated is wide. It is possible to prevent the scattering of In FIG. 10, the broken line indicates the scattering of the fragments BP of the disassembly material, and the broken line arrow indicates that the fragments BP of the disassembly material are blocked by the sheet member 452B and dropped.

  In addition, a sheet member and a frame member are not limited to the said structure. In addition, a plurality of shatterproof members may be used as in the case of the water sprayer of the above embodiment.

  Moreover, in the said embodiment, although the backhoe was used for disassembly operation, this invention is not limited to this.
