Description

  The present invention relates to a simple temporary equipment cleaning apparatus, and more particularly, a simple temporary equipment cleaning apparatus that removes and cleans deposits adhering to temporary equipment by spraying pressurized water ejected from a pressurized water spray gun onto the temporary equipment. About.

  When constructing a building, temporary construction for construction scaffolding such as pipe building frames, plate-like scaffolding plates, pipe bracing, and L-joints for connecting pipes to form a building frame Assemble the scaffolding according to the height of the building using the equipment. The temporary equipment constituting the scaffold is attached with deposits such as concrete at the time of placing concrete and paint at the time of painting the outer wall. Therefore, after dismantling the scaffold after completion of the work, it is necessary to perform a cleaning work to remove the deposits in preparation for the next work.

  Cleaning methods include a method of scraping off deposits with a rotating brush of wire, shot blasting, etc., and a method of cleaning the deposits by spraying pressurized water sprayed from a pressurized water spray gun onto temporary equipment. Has problems with noise and dust compared to the pressurized water system.

  As a cleaning operation of temporary equipment by a general pressurized water method, the temporary equipment to be cleaned by the cleaning operator A is placed on a cleaning floor such as concrete, and the pressurized water jetted from the pressurized water ejection gun held by the cleaning operator B in his hand. On temporary equipment. As a result, after the surface of the temporary equipment has been cleaned, the cleaning operator A turns over the temporary equipment so that the back surface is the upper side, and the cleaning operator B cleans the back surface with the pressurized water jet gun. That is, by performing cleaning by two cleaning workers A and B, the cleaning labor is reduced and the cleaning efficiency is increased.

  However, cleaning temporary equipment with only human power cannot sufficiently reduce cleaning work labor and cannot achieve sufficient improvement in cleaning efficiency. Further, the pressure of the pressurized water ejected from the pressurized water ejection gun used for the cleaning operation of the temporary equipment is dangerous, for example, at an ultrahigh pressure of 100 MPa. Further, since the spraying and splashing of pressurized water is applied to the cleaning operator, there is a problem that the working environment is bad.

  From such a background, the present applicant has proposed Patent Document 1 as automatic cleaning of a pressurized water type temporary equipment cleaning apparatus.

  The temporary equipment cleaning apparatus of Patent Document 1 includes a transport means for shuttle transporting temporary equipment between a carry-in / carry-out stage and a cleaning stage, and a holding jig for detachably holding the temporary equipment on the transport means in a vertical state. And a pair of cleaning robots arranged opposite to each other in the cleaning stage and equipped with a pressurized water spray gun, a cleaning chamber surrounding the cleaning stage, and a counter-matching means for preventing the cleaning robots from being in a co-matching state, The robot includes a handling robot provided on the carry-in / carry-out stage, and a control unit that controls at least the transfer unit, the cleaning robot, and the handling robot. Thereby, since the temporary equipment can be automatically cleaned, not only the cleaning efficiency can be remarkably improved, but also the cleaning work labor and the cleaning work environment of the cleaning operator can be remarkably improved.

Japanese Patent Laying-Open No. 2015-226893

  However, the temporary equipment cleaning apparatus that is highly mechanized and performs automatic cleaning in Patent Document 1 has a problem that the apparatus cost is high.

  For this reason, there is a demand for a simple temporary equipment cleaning apparatus that can reduce the cost of the apparatus and can greatly improve the cleaning work labor, the cleaning work environment, and the cleaning efficiency of the cleaning worker as compared with the case of only human power.

  The present invention has been made in view of such circumstances, and provides a simple temporary equipment cleaning apparatus that can improve the cleaning work effort and the cleaning work environment of a cleaning operator and can realize low-cost apparatus costs. With the goal.

  In order to achieve the above object, a simple temporary equipment cleaning apparatus according to the present invention is a simple temporary equipment cleaning apparatus for cleaning temporary equipment for a construction scaffold with pressurized water, and a cleaning unit for cleaning the temporary equipment, A carriage unit that carries unwashed temporary equipment into the washing unit and carries out the temporary equipment after washing, and the washing unit is provided above the washing stage, the washing stage on which the washing table is formed, A pressurized water ejection gun having an ejection head for ejecting pressurized water, and a scattering prevention chamber which surrounds the pressurized water ejection gun to prevent the scattering of pressurized water and which has a gate-shaped opening for carrying in and out temporary equipment at the bottom. The carriage part has a wire mesh member on which temporary equipment is placed, the front part in the loading direction is placed non-fixed on the washing table, and the rear part is arranged on a handle part arranged outside the washing part. The supported mounting table and the mounting table A plurality of omnidirectional moving bodies that are provided on the surface and movably support the mounting table on the cleaning table, and provided on the handle, support the rear portion of the mounting table at the height of the cleaning table and casters at the lower end. And a leg portion.

  According to the simplified temporary equipment cleaning device of the present invention, when the cleaning operator places the temporary equipment to be cleaned on the wire mesh member of the mounting table, the front portion of the mounting table is placed non-fixed on the cleaning table. Then, a carriage having a simple structure in which the rear portion is supported by a leg portion having a caster via a handle portion is pushed to carry the mounting table into the washing table of the washing unit.

  Then, in the cleaning table, pressurized water is sprayed to the temporary equipment from the pressurized water spray gun surrounded by the scattering prevention chamber, and the mounting table is moved back and forth and left and right by the omnidirectional moving body on the cleaning table, so that the pressurized water is supplied to the temporary equipment. To be sprayed evenly. After cleaning the temporary equipment in the cleaning section, the cleaning operator pulls the carriage section and carries out the temporary equipment placed on the mounting table from the cleaning section.

  As described above, the simplified temporary equipment cleaning apparatus of the present invention simply carries uncleaned temporary equipment into the cleaning section in the carriage section, cleans it in the anti-scattering chamber, and removes it from the cleaning section after cleaning. Temporary equipment can be cleaned with a simple operation.

  As a result, the cost of the apparatus can be reduced, and the cleaning work effort, the cleaning work environment, and the cleaning efficiency of the cleaning operator can be greatly improved as compared with the case of only human power.

  In another aspect of the present invention, it is preferable to have a drop-off prevention mechanism for preventing the front portion of the mounting table placed non-fixed on the washing table from falling off the washing table.

  As a result, even when the front part of the mounting table in the carriage unit has a simple structure in which the front part of the mounting unit is not fixedly placed on the cleaning table of the cleaning unit, when the temporary equipment is carried out of the cleaning unit, The front part does not fall off the washing table. Therefore, if the front part of the mounting table falls off the cleaning table, the extra work of re-loading the front part of the mounting table onto the cleaning table can be eliminated, so that the cleaning work labor can be reduced.

  In another aspect of the present invention, the drop-off prevention mechanism is formed at least in the drainage groove on the rear side in the carry-in direction among the drainage grooves formed in a concave shape in the radial direction around the washing table, and has a height of the outer wall of the drainage groove. The step groove structure is lower than the height of the surface of the washing table, and the omnidirectional moving body provided at the tip in the loading direction among the omnidirectional moving bodies provided on the mounting table of the carriage unit. It is preferable that the omnidirectional mobile body is formed in such a size that it falls into the drainage groove and gets caught.

  As a result, when the temporary equipment placed on the mounting table is carried out of the cleaning unit, the omnidirectional mobile body at the tip of the mounting table is immediately before the dropping table is dropped from the cleaning table. Since it is caught in the structure, the front portion of the mounting table does not fall off the cleaning table.

  In addition, when carrying temporary equipment into the cleaning section, the height of the outer wall of the drainage groove on the rear side in the loading direction of the drainage groove is a step groove structure that is lower than the height of the surface of the cleaning table, In addition, the rear portion of the mounting table is supported at the height of the cleaning table by the legs of the carriage unit. Therefore, if the omnidirectional mobile body at the tip in the loading direction of the mounting table is placed on the cleaning table, the subsequent omnidirectional mobile body is not caught in the drainage groove.

  In another aspect of the present invention, it is preferable that an opening having a diameter equal to or greater than a diameter at which the pressurized water ejected from the ejection head hits the surface of the cleaning table is formed immediately below the ejection head in the cleaning table. As a result, the pressurized water that has passed through the wire mesh member of the mounting table does not hit the surface of the cleaning table and scatter, so that the spray of pressurized water is less likely to scatter outside the scattering prevention chamber, thereby further improving the cleaning work environment.

  In another aspect of the present invention, it is preferable that a transparent plate is erected at the rear end in the loading direction of the mounting table. Thereby, even if pressurized water is scattered outside the scattering prevention chamber, it can be prevented from hitting the cleaning operator by the transparent plate of the mounting table, so that the cleaning work environment can be further improved.

  In another aspect of the present invention, it is preferable that an air ejection nozzle is provided in the vicinity of the ejection head to blow off the scattered and splashed pressurized water ejected from the ejection head to the front side in the loading direction of the cleaning table. As a result, it is possible to further prevent the pressurized water from splashing outside the scattering prevention chamber and hitting the cleaning operator, thereby further improving the cleaning work environment.

  In another aspect of the present invention, it is preferable that a cylindrical brush member protruding from the tip of the ejection head is attached to the ejection head. As described above, by projecting the cylindrical brush member from the tip of the ejection head, it is difficult for the pressurized water to scatter around, and the ejection sound of the pressurized water can be reduced, so that the cleaning work environment can be further improved.

  In another aspect of the present invention, a fixing jig for fixing the temporary equipment to the mounting table according to the shape of the temporary equipment is provided, and the fixing jig is attached to and detached from the holding portion for holding the temporary equipment and the opening of the wire mesh member. It is preferable to have an insertion leg that fixes the holding portion to the wire mesh member by freely inserting. Thereby, even if ultra-high pressure pressurized water is sprayed on the temporary equipment, the temporary equipment does not move or jump on the mounting table. Accordingly, since there is no need to replace the moved temporary equipment, not only the cleaning work labor can be reduced, but also the work efficiency is improved.

  As a fixing jig, the holding part is composed of a holding frame, female screws formed at a plurality of positions of the holding frame, and a plurality of rod-like members formed with male screws screwed into the female screws. Is preferred. Thereby, it can respond to temporary equipment of various shapes.

  According to the simplified temporary equipment cleaning apparatus of the present invention, the cost of the apparatus can be reduced, and the cleaning work effort, the cleaning work environment, and the cleaning efficiency of the cleaning operator can be greatly improved as compared with the case where only human power is used.

And an omnidirectional moving body 36 (see FIG. 5) that supports the pedestal, and a leg that is provided on the handle portion 32 and supports the rear portion of the mounting table 34 at the height of the cleaning table 16 and has a caster 38 at the lower end. Part 40.

<Detailed structure of the cleaning part>
As shown in FIGS. 2 and 3, the cleaning stage 18 of the cleaning unit 12 mainly includes a cleaning table 16 having a drain groove 46 with a concave radial cross section formed in the periphery, and a cleaning table 16 via a pedestal 44. It is comprised with the base frame 19 to support. The relationship between the cleaning table 16 and the pedestal 44 is substantially the same as the pedestal 44 having a drainage groove 46 around the rectangular pedestal 44 in which side plates 42 and 42 are erected on both side ends in the lateral direction. A rectangular washing table 16 having a size is placed and fixed.

  As shown in FIG. 3, the side plate 42 of the pedestal 44 is formed to be higher than the position of the surface of the cleaning table 16. Further, out of the drain grooves 46 having a concave radial cross section formed around the cleaning table 16, at least the outer wall 46B of the drain groove 46A formed on the rear side (B direction side) of the cleaning table 16 (FIG. 1 and FIG. 1). 3), the height of the surface 16A of the cleaning table 16 is lower than the height of the surface 16A. In the step groove structure, the carriage unit 14 in which the front portion of the mounting table 34 is non-fixedly supported on the cleaning table 16 (synonymous with the surface 16A) is moved in the unloading direction B with respect to the cleaning unit 12. Sometimes, a part of the configuration of the drop-off prevention mechanism 48 is formed so that the mounting table 34 does not fall off the cleaning table 16. A detailed description of the dropout prevention mechanism 48 will be described later.

  The anti-scattering chamber 26 includes a rectangular cylindrical chamber portion 50 that is open at the top and bottom, a portal opening 24 formed in the lower portion of the chamber portion 50, and a lower end on the rear side (B direction side) of the chamber portion 50, that is, A plurality of strip-shaped members 52, 52... Hanging from the upper end of the gate-shaped opening 24 to the surface 16 A of the cleaning table 16.

  The chamber portion 50 is configured such that the inside of the chamber portion 50 can be seen from the outside by fitting a transparent window 56 (for example, a transparent acrylic plate) into a frame member 54 that forms a square tube. Thereby, the ejection situation of the pressurized water ejected from the ejection head 20 of the pressurized water ejection gun 22 and the cleaning situation in which the temporary equipment W is cleaned can be visually observed.

  Further, the central surface portion of the rear surface side (surface in the B direction) of the chamber portion 50 is supported by the frame member 54 so as to be freely opened and closed via a hinge 58 and can be opened and closed by the lock member 60 in a closed state. A window 62 (see FIG. 1) is formed. Thereby, by opening the opening / closing window 62, it is possible to perform the attaching operation, the detaching operation, the adjustment of the ejection head 20 and the like of the pressurized water ejection gun 22 disposed inside the scattering prevention chamber 26.

  Further, by forming the portal opening 24 in the lower portion of the chamber portion 50, the mounting table 34 of the carriage unit 14 on which the temporary equipment W is mounted between the lower end surface of the chamber unit 50 and the surface 16 </ b> A of the cleaning table 16. The opening space part which can pass is formed. That is, the height of the gate-shaped opening 24 needs to be a height that allows the portal-shaped opening 24 to pass in a state in which the temporary equipment W is mounted on the mounting table 34 of the carriage unit 14. Further, the ejection head 20 of the pressurized water ejection gun 22 is disposed above the opening space of the portal opening 24, and the temporary equipment W mounted on the mounting table 34 is temporarily installed after passing through the portal opening 24. Pressurized water is sprayed on the equipment W.

  Further, by suspending a plurality of transparent strip-shaped members 52 in the portal opening 24, the pressurized water ejected from the ejection head 20 is prevented from scattering from the rear side (B direction side) of the chamber portion 50 to the outside. . In FIG. 1, the strip-shaped member 52 is not provided in the central portion of the rear side of the chamber portion 50 through which the mounting table 34 passes, but may be provided.

  As shown in FIG. 3, the pressurized water ejection gun 22 is disposed in the scattering prevention chamber 26 in the vertical direction (direction perpendicular to the ground). The pressurized water ejection gun 22 includes an ejection head 20 disposed above the cleaning table 16, a connection adapter 64 disposed above the ejection head 20, and a pressurized water pipe 66 that connects the ejection head 20 and the connection adapter 64. Is done. The middle of the pressurized water pipe 66 is held by a holding member 68 supported by the frame member 54 of the chamber unit 50.

  If the holding member 68 is configured so that the pressurized water pipe 66 can be detachably held on the holding member 68, only the pressurized water ejection gun 22 can be removed from the cleaning unit 12 and used alone. As the attachment / detachment structure between the holding member 68 and the pressurized water pipe 66, for example, a structure in which the holding member 68 is tightened with a screw can be adopted. However, it is desirable to adopt a clamp structure using a toggle clamp so that the attachment / detachment can be easily performed without using a tool. .

  Then, high-pressure water from an ultra-high pressure plunger pump (not shown) is supplied to the pressurized water ejection gun 22 through the high-pressure water supply hose 70, the connection adapter 64, and the pressurized water pipe 66. Further, as shown in FIG. 1, a switch button 74 for turning ON / OFF the pressurized water ejection gun 22 is provided on the side of the cleaning unit 12. Thus, when the switch button 74 is turned ON, ultrahigh pressure pressurized water is jetted from the ejection head 20 toward the cleaning table 16 as a jet flow. The pressure of the pressurized water ejected from the ejection head 20 is in the range of 30 to 300 MPa, more preferably 100 to 150 MPa. The amount of pressurized water ejected from the ejection head 20 is preferably in the range of 15 to 25 liters / minute.

  FIG. 6 is a schematic cross-sectional view showing an example of the ejection head 20. A nozzle head 76 is provided at the tip of the pressurized water pipe 66, and a plurality of nozzles 78 are provided on the tip of the nozzle head 76 (the surface facing the cleaning table 16). , 78... Are provided. The nozzle head 76 is covered with a cylindrical head cover 80, the surface on the nozzle 78 side is opened, and the opposite surface side of the nozzle 78 is supported by the pressurized water pipe 66.

  In addition, a cylindrical brush member 82 protruding from the tip of the head cover 80 can be mounted around the head cover 80 of the ejection head 20. The brush member 82 is a member in which brush bristles are gathered. By mounting the brush member 82 on the ejection head 20, it is possible to prevent the pressurized water from being scattered to the surroundings and to expect a silencing effect to reduce the ejection sound of the pressurized water. Although not shown, a rotation mechanism that rotates the nozzle head 76 around the pressurized water pipe 66 may be provided.

  A distance H (see FIG. 3) from the front end surface (lower end surface) of the ejection head 20 to the surface 16A of the cleaning table 16 allows the temporary equipment W placed on the placement table 34 of the carriage unit 14 to pass through and from the ejection head 20. It is necessary to have a height at which the temporary equipment W can be efficiently washed with the jetted pressurized water. When the brush member 82 is mounted on the ejection head 20, the temporary equipment W mounted on the mounting table 34 can pass through a distance H from the tip surface (lower end surface) of the brush member 82 to the surface 16 </ b> A of the cleaning table 16. It is necessary to make such a distance. Therefore, the holding position of the pressurized water ejection gun 22 held by the holding member 68 of the chamber unit 50 may be adjusted as appropriate.

  In order to facilitate the adjustment of the holding position of the pressurized water jet gun 22, an elevating device (not shown) is attached so that the holding member 68 holding the pressurized water jet gun 22 can be raised and lowered with respect to the frame member 54. preferable. As the elevating device, any device may be employed. For example, a rack and pinion mechanism similar to a mechanism for moving the lens barrel of the optical microscope up and down can be employed. At that time, it is desirable to provide a lock mechanism that can be securely fixed at an arbitrary position.

  Further, it is desirable that a tilting mechanism (not shown) is installed on the holding member 68 so that pressurized water can be applied to the object to be cleaned from an oblique direction, not from the vertical direction (directly above). As the tilting mechanism, for example, a shaft fixed to one side for enabling the holding member 68 to rotate with respect to the frame member 54, a bearing fixed to the other receiving the shaft so as to rotate, The lock mechanism can be configured to be fixed at a rotation angle.

  Accordingly, the pressurized water jet gun 22 can be tilted by rotating the holding member 68 to a predetermined angle with respect to the frame member 54 and fixed, and pressurized water can be applied obliquely to the object to be cleaned. In FIG. 3, when the holding member 68 is rotated and tilted with respect to the frame member 54, the pressurized water ejection gun 22 is inclined in the short direction, so that the pressurized water can be applied to the object to be cleaned from the oblique short direction.

  In the case where it is desired to apply pressurized water to the object to be cleaned from an oblique longitudinal direction, the holding member 68 is rotated 90 degrees around the longitudinal direction of the pressurized water ejection gun 22 in FIG. Should be adopted.

  Thereby, if the holding member 68 is rotated and tilted in this state, the pressurized water can be applied to the object to be cleaned from an oblique direction in the longitudinal direction. It is preferable to apply pressurized water to the temporary cleaning equipment from the oblique longitudinal direction, in particular, obliquely from the carrying-out direction A to the carrying-out direction B (tilt so that the tip of the pressurized water jet gun 22 comes to the front of the washing operator). As a result of evaluating the shape of a particularly long temporary cleaning equipment, it was found that the cleaning effect is high by applying pressurized water at an angle of 15 degrees from the vertical direction (particularly an angle of 15 degrees).

  Therefore, in the cleaning of the temporary cleaning equipment by the apparatus according to the present invention, it is preferable that the pressurized water ejection gun 22 can be tilted up to 15 degrees from the vertical so that the front end of the pressurized water ejection gun 22 comes closer to the cleaning operator. Even if it is tilted at an angle larger than that, a large cleaning effect cannot be expected and there is no meaning, and the apparatus cost increases.

  The orientation of the non-long temporary cleaning equipment may be adjusted at the time of installation, but the long temporary cleaning equipment can only be installed with the longitudinal direction being the AB direction in the apparatus of the present invention. In that case, we investigated the angle of applying pressurized water and the cleaning effect on various types of long-term temporary cleaning equipment. By applying pressurized water at an angle of 15 degrees from the vertical direction (especially an angle of 15 degrees), the cleaning effect was obtained. Is found to be high.

  In the present embodiment, one pressurized water ejection gun 22 is provided. However, a plurality of pressurized water ejection guns 22 may be provided along the longitudinal direction (or the direction perpendicular to the longitudinal direction) of the cleaning table 16. In this case, a plurality of pressurized water ejection guns 22 may be surrounded by one scattering prevention chamber 26, or a plurality of pressurized water ejection guns 22 surrounded by one scattering prevention chamber 26 may be arranged. .

  Further, as shown in FIG. 7, in the vicinity of the ejection head 20, a plurality of air ejection nozzles 84, 84, which blow off the splashes and splashes of pressurized water ejected from the ejection head 20 to the front (direction A) of the cleaning table 16. Is preferably provided. Thereby, when carrying the carriage part 14 in the washing | cleaning part 12 and wash | cleaning the temporary equipment W, it is further prevented that the spraying and splashing of the pressurized water which ejected from the ejection head 20 apply to the washing operator P (refer FIG. 1). it can. When this inventor produced and evaluated the prototype of this invention, he discovered that pressurized water splashed to the operator P and workability | operativity was bad. Therefore, as a result of diligent efforts, it was found that by providing the air ejection nozzle 84, scattering of the pressurized water to the worker P could be prevented, and an extremely good result was obtained when an experiment was performed with an actual prototype.

  Further, in this case, as shown in FIG. 7, an opening that is equal to or larger than the diameter at which the pressurized water ejected from the ejection head 20 hits the surface 16 </ b> A of the cleaning table 16 at a position directly below the ejection head 20 on the surface 16 </ b> A of the cleaning table 16. It is preferable to form the portion 86, and it is more preferable to form the equivalent opening 86.

  The temporary equipment W has a rod-like, triangular, L-shaped pipe and the like in addition to a plate-like shape such as a plate-like scaffold plate (not shown), and the shape and size thereof are various. Therefore, it is rare that all of the pressurized water ejected from the ejection head 20 hits the temporary equipment W placed on the wire mesh member 30 of the placement table 34, and usually passes through the wire mesh member 30 and hits the cleaning table 16. Since the pressurized water hitting the cleaning table 16 is splashed and scattered, the working environment is deteriorated.

  However, as in the present embodiment, the above-described opening 86 is formed at a position directly below the ejection head 20 on the surface 16A of the cleaning table 16, so that the pressurized water that has passed through the wire mesh member 30 passes through the opening 86. Since it does not collide with the washing table 16, the generation of splashes can be suppressed.

  As shown in FIGS. 3 and 8, the contaminated water recovery mechanism 28 is formed around a cylindrical body 88 extending below the cleaning table 16 from an opening 86 formed in the cleaning table 16 and around the cleaning table 16. The drainage groove 46 for discharging the cleaning contaminated water collected on the cleaning table 16 and the storage provided below the cleaning table 16 and into which the cleaning contaminated water that has passed through the cylinder 88 and the cleaning contaminated water that has flowed into the drainage groove 46 flow in. A tank 90. The storage tank 90 is disposed in the base frame 19.

  The cleaning contaminated water that has flowed into the drainage groove 46 from the cleaning table 16 flows into the storage tank 90 through the two drainage pipes 92, 92 extending obliquely downward from the drainage groove 46.

  Further, it is preferable that the lower surface of the cylinder 88 is closed and discharged to the storage tank 90 from an outflow pipe 94 extending from the side of the cylinder 88. When the lower surface of the cylindrical body 88 is opened, the pressurized water that is ejected from the ejection head 20 and passes through the cylindrical body 88 directly hits the washed contaminated water stored in the storage tank 90, and the washed contaminated water is exposed to the outside. It becomes easy to scatter. However, as in the present embodiment, the bottom surface of the cylinder 88 is closed and discharged from the outflow pipe 94 provided on the side of the cylinder 88 to the storage tank 90, thereby preventing the cleaning contaminated water from scattering.

  In addition, the storage tank 90 is provided with a discharge pipe 96 with a valve 96A for discharging the accumulated cleaning contaminated water and a plurality of casters 98, 98... (See FIG. 3). Accordingly, when the storage tank 90 is filled with the cleaning contaminated water, the cleaning tank 90 can be moved to a wastewater treatment facility or the like to process the cleaning contaminated water.

<Detailed structure of bogie>
As shown in FIGS. 4 and 5, the mounting table 34 of the carriage unit 14 includes a plurality of mounting tables 34 between two parallel trees 100 and 100 that are long in the longitudinal direction (AB direction) of the carriage unit 14. Are formed by stretching a wire mesh member 30 on a rectangular frame 104 to which the crosspieces 102, 102... (6 in FIG. 4) are passed. As the metal mesh member 30, a mesh member having many openings such as an expander metal, a punching metal, a metal mesh, and a grating can be used, but an expander metal is most preferable. The vertical tree 100 is formed so that its height is higher than the surface of the wire mesh member 30 (see FIG. 5).

  The length of the mounting table 34 in the longitudinal direction (AB direction) is formed substantially equal to the length of the cleaning table 16, and the width in the short side direction (XY direction) is narrower than the width of the cleaning table 16. The For example, the width D1 of the mounting table 34 is preferably about half of the width D2 of the cleaning table 16 (see FIG. 2). Thereby, since the mounting table 34 can be moved back and forth and right and left on the cleaning table 16, the pressurized water from the ejection head 20 can be sprayed uniformly on the temporary equipment W mounted on the mounting table 34. The cleaning effect can be improved.

  A plurality of omnidirectional mobile bodies 36 are provided on the lower surface of the crosspiece 102 provided on the frame 104 of the mounting table 34. In FIG. 4, three omnidirectional mobile bodies 36 are provided on each crosspiece 102 and a total of 18 are provided on the mounting table 34, but the number is not limited to this. In short, it is sufficient that the mounting table 34 can move smoothly back and forth and right and left on the cleaning table 16. The omnidirectional mobile body 36 may be anything as long as the mounting table 34 can move smoothly back and forth and right and left on the cleaning table 16, but a ball that receives a single main ball with a number of sub-balls and supports them. A ball bear composed of a receiving part is preferred. In this embodiment, a ball bear is shown.

  As shown in FIGS. 1 and 5, the handle portion 32 and the leg portion 40 that support the base end portion (the end portion in the B direction of the mounting table) of the mounting table 34 are integrally formed. It is formed by passing two horizontal pipes 108, 108 between two parallel vertical pipes 106, 106 extending in an inverted L shape from the end. One of the two horizontal pipes 108 is provided at an L-shaped bent position of the vertical pipe 106, and the other horizontal pipe 108 is provided at a lower position of the vertical pipe 106.

  Casters 38 are provided at the lower ends of the two parallel vertical pipes 106, 106, and the casters 38 run on a floor surface 39 on which the temporary equipment cleaning device 10 is disposed.

  The cleaning operator P holds the upper horizontal pipe 108 and pushes or pulls the carriage unit 14 to carry in and out the temporary equipment W mounted on the mounting table 34 to the cleaning table 16 of the cleaning unit 12. . The number of horizontal pipes 108 is not limited to two, and the position held by the cleaning operator P is not limited to the upper horizontal pipe 108.

  Further, as shown in FIGS. 1 and 5, the base end of the mounting table 34 is transparent at the same height as the gate opening 24 of the anti-scattering chamber 26 described above, which is the same as the width of the mounting table 34 and is about 10 cm higher. A plate 110 (for example, an acrylic plate) is erected.

  Further, as described above, since the front portion of the mounting table 34 of the carriage unit 14 is only placed on the cleaning table 16 of the cleaning unit 12 in a non-fixed manner, the mounting table 34 is disposed on the carriage unit 14. A drop-off prevention mechanism 48 for preventing the drop-off from the 16 is provided.

  As shown in FIG. 2, the dropout prevention mechanism 48 is formed at least in the drainage groove 46 </ b> A on the rear side (B direction side) of the drainage groove 46 having a concave radial cross section around the cleaning table 16. The step groove structure in which the height of the outer wall 46B of the groove 46A is lower than the height of the surface 16A of the cleaning table 16, and the front end portion in the loading direction A of the omnidirectional moving body 36 provided on the mounting table 34 of the carriage unit 14. The omnidirectional mobile body 36A is formed in such a size that the omnidirectional mobile body 36A is caught in the drainage groove 46A.

  Thereby, in order to carry out the temporary equipment W after cleaning by the cleaning unit 12, when the mounting table 34 of the carriage unit 14 is pulled in the unloading direction B, the mounting table 34 is just before the mounting table 34 is dropped from the cleaning table 16. The omnidirectional moving body 36A at the tip of 34 falls into the drainage groove 46A on the rear side of the cleaning table 16 and is caught. Therefore, since the movement of the carriage unit 14 in the carry-out direction B is stopped, it is possible to prevent the front part of the mounting table 34 of the carriage unit 14 from dropping from the cleaning table 16.

  Further, when the temporary equipment W is carried into the cleaning section 12, a step groove structure is formed in which the height of the outer wall 46B of the drain groove 46A on the rear side in the loading direction A is lower than the height of the surface 16A of the cleaning table 16. In addition, the rear portion of the mounting table 34 is supported at the height of the cleaning table 16 by the legs 40 of the carriage unit 14. Therefore, as long as the omnidirectional mobile body 36A at the tip of the loading table 34 in the loading direction A is placed on the cleaning table 16, the subsequent omnidirectional mobile body 36 is not caught in the drain groove 46A. Accordingly, the mounting table 34 of the carriage unit 14 can be smoothly carried in and moved.

  In this way, the drop-off prevention mechanism 48 is constructed without requiring a special member as the drop-off prevention mechanism 48 by a simple configuration in which the drain groove 46A formed in the cleaning table 16 is simply formed in the step groove structure. Can do.

  The dropout prevention mechanism 48 is configured by the relationship between the drainage groove 46A and the omnidirectional mobile body 36A described above, and, for example, a retractable pin (not shown) provided on the mounting table 34 of the carriage unit 14 includes a drainage groove. It can also be set as the structure which appears and disappears in 46A. In this case, if a ball bear is provided at the tip of the retracting pin, smooth movement of the mounting table 34 on the cleaning table 16 is not hindered. Also in the case of this drop prevention mechanism 48, the drain groove 46A of the washing table 16 is used as a part of the configuration of the drop prevention mechanism 48, so that the drop prevention mechanism 48 can be constructed with a simple configuration.
