Description

  The present invention protects a worker who sprinkles water from fragments such as concrete, stone, etc. that may scatter from a dismantling / crushing site while sprinkling water toward dust generated during dismantling work of a building or the like in a quarry. The invention relates to a protection device with a water spray function.

  During dismantling with existing crushers such as concrete structures, breakers, etc., water is released toward the dust source to prevent the scattering of dust generated from the dismantling place (Patent Documents 1 to 3) When demolishing the frame, it is also necessary to grind the concrete block to a certain size or less for the convenience of loading on the dump truck.

  Since a concrete block is compressed by using a crusher or the like and crushed by being cut, there is a risk that the crushed pieces may be scattered to the water discharge position at the time of grinding.

  In the patent documents 1-3, in order to prevent scattering of the dust generated at the time of dismantling a structure etc., although the method of sprinkling (water discharge) toward the generation source of the dust is presented, The method of protecting the installation position from the above-mentioned shattering is not shown.

Japanese Utility Model Laid-Open Publication No. 5-71355 (claim 1, paragraphs 0009 to 0011, FIG. 1) Unexamined-Japanese-Patent No. 8-326331 (Paragraph 0022, FIGS. 1-3) Unexamined-Japanese-Patent No. 2004-169461 (Paragraphs 0014-0016, 0022-0025, FIG. 1, FIG. 2)

  Since the flat panel which can mount a watering nozzle is arrange | positioned on the structure side of the scaffold upper part assembled to the periphery of the structure dismantled to the patent document 3 from the crushed pieces which scatter a panel, It is also possible to use it as a shield to protect.

  However, since the panel is inclined from the lower end to the upper end toward the structure side and the direct injection nozzle for preventing the scattering of dust is connected to the upper end of the panel (FIG. 1) It is difficult to say that the function of preventing the shattering pieces scattered to the position of the nozzle can be achieved. In addition, since the panel is fixed on the scaffold assembled in multiple layers around the structure, it should be watered (used) according to the movement of the dismantling place of the structure among the direct injection nozzles installed in multiple places You have to change the direct injection nozzle.

  From the above background, the present invention proposes a protection device with a water sprinkling function which can reliably protect the installation position of a water sprinkling nozzle which is a water sprinkling source from the scattering of crushed pieces and can follow the movement of a dismantling place.

The water protection function protection device according to the present invention is characterized in that the frame has a net, and one end is connected to the frame, the other end is in contact with the ground surface or the floor surface, and the frame is the ground surface Or a support material supported on a floor surface, and a wheel connected below the frame and movably supporting the frame on the ground surface or floor surface,
An opening is formed in a part of the net, and a nozzle connected to a hose for water sprinkling is held in the opening through the opening.

  As shown in FIG. 1 etc., the frame 2 is assembled in a square shape from, for example, the vertical frames 21 21 arranged in parallel in the width direction and the horizontal frames 22 22 arranged in parallel in the height direction. The shape does not have to be a shape, and may be formed in a polygonal shape, a circular shape including an ellipse, a track shape (rounded rectangle), or the like.

  The net 3 is only required to have a function to protect workers located on the back side of the net 3 from crushed pieces scattered from the dismantling source and a visual recognition function that allows the water spray target to be visible from the back side of the net 3. In most cases, a wire mesh is used which is resistant to breakage or damage to the shattered pieces and can protect the shatters. However, the net 3 is not necessarily made of metal, and a net made of a reinforcing fiber or a synthetic resin may be used. The metal mesh 3 includes expanded metal and punching metal. "The back of the net 3" refers to the back (back) side when viewed from the water spray target side.

  The nozzle 6 is held at the opening 3a in a state where the nozzle 3 is inserted through the opening 3a, whereby the connection port 6a to the hose 12 is located on the back side of the frame 2 and the water discharge port 6b protrudes to the front side of the frame 2 . The discharge port 6b of the nozzle 6 protrudes from the opening 3a to the front surface of the frame 2 so that the discharge water is directed to the front surface side of the frame 2 (network 3) while operating the nozzle 6 on the back side of the frame 2 (network 3). It becomes possible to release. The nozzle 6 is held directly at the opening 3a or indirectly via the holding tool 8 or the like (claim 2).

  A net 3 capable of protecting shredded pieces on the substantially entire surface of the frame 2 and the nozzle 6 can be operated on the back side of the frame 2 (net 3) to discharge water at the installation position of the nozzle 6 that is the water source. It is possible to reliably protect a person from crushed pieces that are scattered with kinetic energy from the crushing source. "Substantially" means that an opening 3a for inserting the nozzle 6 is formed in a part of the entire surface of the frame 2, but the meaning of substantially the entire surface of the frame 2 except this opening 3a.

  The backup material 4 is disposed on the back side of the frame 2 and one end thereof is connected to one of the back side of the frame 2 and the like, and the other end is in contact with the ground surface or floor surface. And the frame 2 is stabilized on the ground surface or the like in a state in which the frame 2 is maintained at a constant angle with respect to the vertical surface. The backing material 4 may be connected to the surface side of the frame 2 through the frame 2. The “back of the frame” refers to the side of the frame 2 (the net 3) opposite to the side of the water spray (water discharge) where the operator operates the nozzle 6, and is the same as the back of the net 3.

  The floor surface refers to the upper surface of a floor or slab of concrete or the like constructed or built on the ground surface, or a plate of steel plate or the like installed temporarily. Since the dismantling of the structure is performed at the installation site of the existing structure, the wheel 5 is often installed on the existing concrete slab or on the ground surface after the absence of the slab. The ground surface or floor surface is hereinafter referred to as the ground surface or the like. When the frame 2 includes the vertical frame 21 and the horizontal frame 22, one end of the block 4 is connected to the vertical frame 21 or the horizontal frame 22. If one end of the block 4 is rotatably connected to the frame 2 about a horizontal axis, adjustment of the angle with respect to the vertical plane of the frame 2 and folding of the block 4 can be performed.

  The wheel 5 is rotatably connected to the lower end of the vertical frame 21 or the lower end of the frame 2 such as the lower horizontal frame 22, for example, around a horizontal axis parallel to the axis of the horizontal frame 22. By contacting, the frame 2 is floated from the ground surface, and the frame 2 is supported movably on the ground surface or the like by rolling on the ground surface or the like. The wheel 5 is rotatably connected to the frame 2 by the axle 51 being held rotatably at, for example, the lower end portion of the vertical frame 21 of the frame 2 about a horizontal axis. The wheels 5 are connected to at least a plurality of locations on both sides in the width direction of the frame 2 or at one location in the center in the width direction.

  If, for example, the lower end of the support member 4 is floated from the ground surface or the like by the wheels 5 rolling on the ground surface or the like, the frame 2 (defense device 1) can be As it is possible to move freely on the ground surface etc. and to approach the water spray target, it is possible to spray water intensively to the water spray target reliably. If the braces 4 are arranged in pairs on both sides in the width direction of the frame 2, the frame 2 is stabilized in a stationary state even with one wheel.

  An opening 3a for inserting a nozzle 6 for water sprinkling is formed in part, such as a central portion on the elevation surface of the net 3, and the nozzle 6 is directly or indirectly attached to the opening 3a in a state of inserting the opening 3a. The valve for controlling the amount of water and the knob are located on the back of the net 3, and the discharge port 6b at the tip projects from the net 3 to the surface side. More specifically, the support member 7 is installed at a position passing through the opening 3 a and supported by the frame 2, and the support member 7 is connected to a holding tool (clamp) 8 for holding the nozzle 6. (2). The installation direction of the support member 7 is not limited to horizontal.

  The gripping tool 8 is connected or fixed to the support member 7 with the axis of the nozzle 6 facing, for example, in a direction perpendicular to or close to the surface of the frame 2. If the support member 7 is rotatably supported by the support member 7 (claim 3), and if the support member 7 is horizontally installed between, for example, the vertical frames 21 constituting the frame 2 (claim 4), It is easy to adjust the angle of the nozzle 6 with respect to the horizontal. In this case, the angle adjustment with respect to the horizontal of the nozzle 6 can be freely performed without depending on the angle adjustment of the frame 2 by the stay member 4, that is, keeping the frame 2 at a certain angle with respect to the vertical plane.

  The support member 7 is horizontally installed between the vertical frames 21 and 21 (claim 4), and the holding tool 8 is supported by the support member 7 so as to be rotatable around the support member 7 (claim 3 ), The tip of the nozzle 6 can be oriented in any direction in the height direction simply by rotating the nozzle 6 about the horizontal axis, so that the nozzle 6 is more effective than, for example, when the support member 7 is installed in a direction other than horizontal It becomes easy to adjust the angle of.

  The adjustment of the orientation of the frame 2 in the width direction as well as the angle with respect to the horizontal of the nozzle 6 is possible by securing a clearance between the inner peripheral surface of the grip of the gripper 8 and the outer peripheral surface of the nozzle 6 become.

  For example, since the protection device 1 is used regardless of the season, the frame 2 may support a covering material 9 for protecting the worker from the sunshine at the time of the water discharge operation in summer where the influence of the sunshine and the temperature is large. (Claim 5). In this case, the covering member 9 is disposed on the upper side horizontal frame 22 constituting the frame 2 and is supported by the frame 2 in a state of covering the upper side of the side member 4 (claim 5). The covering material 9 has a role as a shade, and also has a function to protect the operator from crushed pieces scattered from the dismantling place (grind source) as well as the mesh 3 stretched on the frame 2, and both. It may have a role.

  For example, the covering material 9 is projected from the upper side horizontal frame 22 toward the worker (the support 4) side and supported in a cantilever state by the horizontal frame 22, or from the horizontal frame 22 or the vertical frame 21 to the side of the worker It is stabilized on the frame 2 by being supported by the overhang member 9 and the upper horizontal frame 22 supported in a cantilever state or the like by the horizontal frame 22 and the vertical frame 21.

  A net is placed on the substantially entire surface of the frame except for the nozzle position, and the nozzle is held at the opening with the opening formed in a part of the net inserted, whereby the nozzle on the back side of the frame Therefore, it is possible to reliably protect the worker who discharges water at the installation position of the nozzle, which is the water source, from the shattering of the shatters.

  Also, in order to connect the wheel that supports the frame movably on the ground surface etc. to the lower part of the frame, move the frame (defensive device) freely on the ground surface etc. according to the reach distance of water discharged from the nozzle. It is possible to approach the watering target and ensure that the watering target is watered intensively.

It is a perspective view showing an example of production of a defense device. It is an enlarged view of the wheel part of FIG. FIG. 2 is an enlarged view of the upper part including the cover of the protection device shown in FIG. 1; (A) is the perspective view which showed the condition in which the nozzle was hold | maintained at the opening of a part of net | network, (b) is the elevation view which showed the example of the holding tool which hold | maintains a nozzle. It is the elevation view which showed the example of manufacture of the defense device which made the frame support the covering material of a simpler type than the example of FIG. It is the perspective view which showed a mode that the covering material of the protection apparatus shown in FIG. 5 was seen from the back side. It is the perspective view which showed a mode that water was sprayed using the protection apparatus shown in FIG. 1 or the position which set | placed the distance away from the generation source toward the generation source of dust. It is an enlarged view of the defense device of FIG.

  In FIG. 1, one end is connected to the frame 2 with the net 3 stretched and the back surface of the frame 2 and the other end is in contact with the ground surface or floor surface (hereinafter ground surface etc.) And a wheel 5 connected below the frame 2 and movably supporting the frame 2 on the ground surface and the like, and the opening 3a formed in a part of the net 3 for water sprinkling The example of manufacture of the protection apparatus with a water spray function (following, protection apparatus) 1 with which the nozzle 6 connected to the hose 12 of this is hold | maintained is shown.

  The frame 2 is, for example, a linear horizontal frame 21, 21 arranged in parallel, and a linear horizontal frame 22, 22 installed between upper and lower ends of the vertical frames 21, 21 and joined to the vertical frames 21, 21. It is assembled from square shape. However, the vertical frame 21 and the horizontal frame 22 are not limited to be linear, and the elevation shape of the frame 2 is not limited to a square. The frame 2 may be formed, for example, in the shape of a combination of a circular arc or an elliptic arc, or a combination with a straight line. Further, the frame 2 is not limited to the vertical frame 21 and the horizontal frame 22, and may be an annularly continuous frame. For the vertical frame 21 and the horizontal frame 22 constituting the frame 2, steel materials such as shaped steel are mainly used in view of processing such as cutting and easiness of joining, but these materials are not limited.

  For example, one end (upper end) of the backup material 4 may be fixed by bolts or welding to the upper side of the upper ends of the vertical frames 21 or 21 or to the back of both sides in the length direction of the upper horizontal frame 22 As shown in 3, it is connected (connected) rotatably around a horizontal axis by a pin or the like. The other end (lower end) of the block 4 contacts the ground surface or the like directly or via a roller, a plate or the like.

  Even when the upper end of the backup material 4 is fixed to the vertical frame 21 or the like, or when it is rotatably connected, the protective device 1 is stabilized without exerting an excessive force on the backup material 4 when the protection device 1 is used. In the drawing, the connecting member 41 is constructed between the lower end portion of the block 4 and the lower portion and the lower portion of the vertical frame 21 and the lower end portion of the block 4 is the vertical frame 21 and the like. Connected and restrained.

  The net 3 is attached to the entire surface or almost the entire surface in the area divided by the frame 2, and an opening 3 a for allowing the nozzle 6 to be inserted is formed in a part, such as a central portion on an elevation of the frame 2. The position of the opening 3a is set so that the operator can easily grasp the nozzle 6 and operate it. The net 3 is attached to substantially the entire surface of the area surrounded by the frame 2 except for the opening 3a, but it is not necessary to cover the entire surface of the frame 2 and scatters on any part of the frame 2 It is acceptable for the openings to be formed to an extent that they do not interfere with the protection of the crushed pieces.

  The periphery of the net 3 is joined and fixed to the frame 2 by welding, screws, welding or the like, or together with a pressing plate by screws or the like so as not to be separated from the frame 2 at the time of collision of crushed fragments. However, the net 3 does not necessarily have to be fixed to the frame 2 all around, and a part of the net 3 in the circumferential direction may be separated from the frame 2 in order to reduce (absorb) the impact at the time of collision. Although expanded metal or the like made of metal is mainly used for the net 3, materials having reinforcing fibers or the like other than metal are also used if they have strength not to receive and break the crushed pieces that are scattered.

  Since the opening 3a portion of the mesh 3 is vulnerable to the collision of the crushed pieces, a rigid reinforcing member 3b having a circularly closed shape such as a circular shape is disposed around the opening 3a. The circumference is fixed to the reinforcing member 3b by welding, bonding, bonding or the like. For example, a steel material such as a highly rigid reinforcing bar is used as the reinforcing material 3b. The reinforcing member 3b is joined at its periphery to the net 3 and is supported by the net 3 from the lower side or the upper side, so that it is stably stopped at the position of the opening 3a. In the drawing, the reinforcing member 3b is formed in a circular shape so that the tip of the nozzle 6 can be freely directed in the height direction and the lateral direction, and the tension of the mesh 3 is dispersed in the reinforcing member 3b. The shape of is arbitrary, and may be formed in a square shape.

  Since the nozzle 6 is held in the opening 3a of the mesh 3, a support member 7 for supporting the nozzle 6 is installed in the frame 2 at a position passing through the opening 3a and joined to the frame 2 at both ends, Be supported. A gripping tool 8 for gripping and holding the nozzle 6 directly is connected to a section of the support member 7 located in the opening 3 a.

  The drawing corresponds to connecting the holding tool 8 to the support member 7 so as to be freely rotatable as described later, and the support member 7 is horizontally installed between the vertical frames 21 constituting the frame 2, and both ends are vertical frames 21 and 21 are fixed by welding or the like, but the support member 7 may be bridged between the horizontal frames 22 constituting the frame 2 in the vertical direction or in a direction inclined in the vertical direction and the horizontal direction.

  If the holding tool 8 is rotatably connected around the support member 7, the tip of the nozzle 6 can be oriented in any direction regardless of the axial direction of the support member 7. The installation direction is also arbitrary, but if the support member 7 is horizontally installed between the vertical frames 21, there is an advantage that it is easy to adjust the vertical direction of the tip of the nozzle 6 (discharge port 6 b). In addition to the above, there is also an advantage that the support member 7 needs to have a minimum length, as the support member 7 works to increase the rigidity of the frame 2.

  The gripping tool 8 grips the nozzle 6 at normal times and when water is jetted, and in that state, it has any function capable of adjusting the angle with respect to horizontal and vertical to some extent, regardless of the form, but in the drawing the outer peripheral surface of the nozzle 6 Since the inner peripheral surface has a shape corresponding to the shape (cylindrical shape) of the above and the nozzle 6 can be easily grasped and released, a clamp for support is used as the grasping tool 8. As shown in FIG. 4-(b), the holding tool 8 is connected rotatably to the main body 8 a directly or indirectly joined to the support member 7 and about the horizontal axis with respect to the main body 8 a, and is closed. At the same time, it comprises three parts, a pressing part 8b for holding the nozzle 6, and a receiving part 8c which is rotatable around a horizontal axis to the main body 8a and to which the pressing part 8b at closing is connected.

  Also in the figure, in order to be able to freely adjust the longitudinal (vertical) orientation of the nozzle 6, the gripper 8 is rotatably connected to the support member 7 around the support member 7, and this longitudinal direction In order to make it possible to adjust the orientation of the support member 7, the support member 7 is horizontally installed between the vertical frames 21, 21 of the frame 2. The fact that the holding tool 8 is rotatably supported around the support member 7 means that the support member 7 is surrounded by the section in the opening 3a of the support member 7 as shown in FIGS. 4- (a) and (b), for example. It becomes possible by covering the cylindrical surrounding material 71 and joining the main body 8a of the holding tool 8 to the surrounding material 71.

  The surrounding material 71 can be rested at an arbitrary angle with respect to the axis of the support member 7 by interposing a filler material such as a fiber material or rubber material which exerts an appropriate frictional force with the outer peripheral surface of the support member 7, for example. Connected to Since the surrounding member 71 can stand at any angle with respect to the axis of the support member 7, if the center of gravity of the nozzle 6 is positioned on the surrounding member 71, the nozzle 6 does not have to be directly held by hand. The nozzle 6 can stand at any angle with respect to the axis of the support member 7.

  In a state in which the holding portion 8b of the holding tool 8 holds the nozzle 6 together with the main body portion 8a, for example, some clearance (air gap) is secured between the inner peripheral surface of the holding portion 8b and the outer peripheral surface of the nozzle 6 The direction of the axis of the nozzle 6 is adjustable horizontally and vertically in the range of. The adjustable direction of the axis of the nozzle 6 in the range of the clearance between the holding tool 8 allows the surrounding member 71 to which the holding tool 8 is directly fixed to be adjustable in angle with respect to the axis of the support member 7 It becomes possible to point the tip of the nozzle 6 in a wide range, in combination with certain things.

  The nozzle 6 is held by the holding tool 8 in a state where the opening 3a is inserted in the thickness direction of the net 3, and in this state, as shown in FIG. 4-(a), a connection port to a hose on the axial direction rear side of the nozzle 6 6 a is located on the back side of the frame 2, and the water outlet 6 b on the front side protrudes to the front side of the frame 2.

  The wheels 5 are disposed at least at one place at the center in the width direction of the frame 2 or at two places on both sides, and are rotatably connected to the frame 2 to float the frame 2 from the ground surface or the like to ground the frame 2 It supports movably on the top. The wheel 5 is attached to each part of the arrangement position, and may be arranged alone (one), but in terms of stability in the state of connection to the frame 2, the two are paired as shown in the figure. Connected to the frame 2.

  When the wheels 5 are paired as shown in FIG. 1 and FIG. 5, both the wheels 5, 5 are connected by the axle 51, but the axle 51 is the vertical frame 21 of the frame 2 or the lower horizontal frame 22 It is held rotatably around its axis. Specifically, as shown in FIGS. 1 and 2, a cylindrical or grooved cross-sectional shape (C shape) rotatably holding the axle 51 on the vertical frame 21 constituting the frame 2 or the lower horizontal frame 22. Etc., and insert the axle shaft 51 in the axial direction through the retainer 52 and slide the axle 51 on the inner peripheral surface of the retainer 52 or slide it via a bearing etc. It is rotatably held by the holder 52. In FIG. 1 etc., the holder 52 is being fixed to the vertical frame 21 of both sides, and a part of net | network 3. As shown in FIG.

  On the upper horizontal frame 22 constituting the frame 2, a covering material 9 as an awning or as a shredder removing material is provided and supported as needed to cover the upper side of the side of the holding material 4 of the frame 2. In the case where the covering material 9 only needs to serve as a shade, as shown in FIG. 5 and FIG. 6, the covering material 9 is a retention material from the upper portions of the vertical frames 21, or both ends of the upper horizontal frame 22, etc. It is sufficient if it comprises the overhanging members 10, 10 projecting in parallel to the four sides, and the shading member 9a which is detachably mounted on the both overhanging members 10, 10. In this case, the overhang members 10 may be connected to the vertical frames 21 or 21 or the horizontal frame 22 in a fixed state, but may be detachably connected to the vertical frame 21 or the like.

  In FIGS. 5 and 6, the overhanging members 10, 10 are bridged between the overhanging members 10, 10 of the portions near the free ends of the overhanging members 10, 10 and the portions positioned on the horizontal frame 22. Are connected to one another, while the lateral frames 22 side of the overhang members 10, 10 are extended until they reach the net 3 of the frame 2, and the extended part is connected to the net 3 using a clip or the like. It is detachably connected to the frame 2.

  In the case where the covering material 9 is used as a shredder piece removal, the overhanging members 10 are, for example, overhanging members 10 from the upper portions of the vertical frames 21, or from both ends of the upper horizontal frame 22 to the backup material 4 side. , 10 are juxtaposed in parallel and fixed in a cantilever state, or the covering member 9 is connected by being connected to a diagonal member 11 installed between the vertical frame 21 as shown in FIG. 1, FIG. 3 and the like. It is supported by the frame 2 in a state in which it projects from the upper horizontal frame 22 to the side of the block 4.

  In this case, since the covering material 9 needs to have the ability to receive fragments falling from above the operator watering behind the frame 2, the overhang member 10, like the frame 2 on which the net 3 is stretched, A bridging member 10a is installed between the free end side tip end portions 10, and the overhang members 10, 10 form, for example, a rectangular closed shape together with the bridging member 10a. A net 3 is stretched in the area divided by the closed projecting members 9, 9 and the connecting material 10a, and is joined to the extending members 10, 10 and the connecting material 10a around the area.

  If the frame 2 side ends of the overhang members 10, 10 are joined to the horizontal frame 22 or the vertical frame 21, the horizontal frame 22 doubles as the connecting member 10a on the frame 2 side connecting the overhang members 10, 10 However, in FIG. 3, the covering member 10 is separable from the frame 2 and the connecting member 10 a is also constructed between the ends of the overhang members 10, 10 on the side of the frame 2 so as to handle the covering member 9 independently. The connecting member 10 a is connected to the horizontal frame 22. In FIG. 3, particularly, the link member 10a on the frame 2 side is rotatably connected to the upper side horizontal frame 22 of the frame 2 via the hinge 10b so that the cover member 9 can be folded when the protection device 1 is not used. ing.
