Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a temporary construction for construction that removes deposits such as concrete and paint that are attached to pipe scaffolds and scaffolding boards used for temporary scaffolding for construction work. The present invention relates to an equipment cleaning device.

[Prior Art] In building construction work, pipe scaffolds are piled up in multiple steps according to the height of the building in the vicinity of the building, and scaffold boards are hung between the pipe scaffolds to form temporary scaffolds. Then, construction work is underway. These pipe scaffolds and scaffolding boards may adhere to concrete when pouring concrete and paint when painting the outer wall, and after dismantling the scaffold when the construction is completed, those deposits are prepared for the next construction. Are working to remove

As a device for removing the deposits, Japanese Patent Laid-Open No. 50-976
No. 18 gazette discloses that when a vertically long roller conveyor is sandwiched between two nozzles that inject high-pressure water, the concrete formwork carried by the roller conveyor stands upright when the concrete formwork passes near the nozzle. A cleaning device dedicated to concrete formwork has been proposed in which the formwork surface is washed with high-pressure water.

In addition, in Japanese Utility Model Laid-Open No. 59-184992, a large number of nozzles for injecting high-pressure water so as to surround the roller conveyor are provided in the middle of the roller conveyor in which two pairs of rubber wheels are connected at equal intervals by a chain. A cleaning device for exclusive use of metal mold steel has been proposed, which cleans the surface of the mold steel by high-pressure water sprayed from the nozzle when the conveyed metal mold steel passes through the nozzle.

[Problems to be Solved by the Invention] However, the above-described conventional cleaning device is a dedicated machine for objects to be cleaned which have substantially the same shape, such as elongated concrete formwork and elongated metal form steel. Since the nozzles that inject high-pressure water also have fixed mounting positions and high-pressure water injection directions according to the object to be cleaned, they are collected from the construction site, such as scaffolding boards or pipe scaffolds with different lengths or widths. It is inconvenient to wash temporary construction equipment such as pipe-shaped single pipe scaffolds with a single device.

In view of the above points, the present invention has an object to provide a cleaning device capable of effectively removing adhering matter from temporary construction equipment of different shapes with one device.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a transfer means for supporting an object to be cleaned on a pedestal and transferring it from one end to the other end. A traveling rail is installed at an upper position so as to be orthogonal to the transfer direction of the object to be cleaned, and a traveling body having an injection nozzle vertically attached to the traveling rail is movably arranged and the injection nozzle generates high-pressure water. A chuck part for connecting both ends of the pipe-shaped object to be cleaned, which is connected to the apparatus and further transferred to the position below the injection nozzle by the transfer means, is arranged on the gantry, and the chuck part is configured to be rotatable. is there.

[Operation] In the present invention, the adhered matter is removed by washing with high-pressure water. When washing temporary equipment having a horizontally long and flat shape such as scaffolding boards and scaffolding frames, The object to be cleaned is placed parallel to the traveling rail on one end side of the transfer means on the gantry, and the transfer means is driven to transfer the object to be cleaned directly below the jet nozzle of the traveling body and stop. Then
High-pressure water is jetted from the jet nozzle, and the jet nozzle is moved along the traveling rail while colliding the high-pressure water all over the surface from one end of the object to be cleaned. When the jet nozzle reaches the other end of the object to be cleaned, the object to be cleaned is sent for a certain distance, and then the traveling body is made to travel in the opposite direction while spraying high-pressure water to clean the remaining part. . This cleaning operation may be performed according to the width of the object to be cleaned. When the cleaning is completed, the high-pressure water injection is stopped, the object to be cleaned is transferred toward the discharge side of the other end, and at the same time the next object to be cleaned is moved to a position directly below the injection nozzle, and the next cleaning is performed. To do.

Further, when the temporary equipment is a pipe, the object to be cleaned is placed on the transfer means, and the transfer means is driven to transfer it to a position just below the injection nozzle, and both ends thereof are clamped by the chuck portions and then rotated. Then, high-pressure water is jetted from the jet nozzle toward the rotating object to be washed, and the jet nozzle is moved and washed in the same manner as described above, and the deposits adhering to the pipe-shaped equipment such as the pipe scaffold are removed. You can
