Description

[Technical field]

[0001] The present invention relates to a jet treatment device. [Background technology]

[0002] Wall cleaning equipment that sprays water jets may be used to clean various wall surfaces, such as ships, buildings, and large tanks, and for pre-treatment before painting (for example, Patent No. 7389011). Summary of the Invention [Problem to be solved by the invention]

[0003] When the surface can be treated with a single pass of the water jet, when an operator enlarges the water jet treatment surface by sliding the treatment surface sequentially, the water jet treatment may overlap an already treated area, thereby extending the work time. The object of the present invention is to reduce overlap between a portion that has already been processed and the portion to be processed next. [Means for solving the problem]

[0004] A first aspect of the present invention is a jet treatment device having an adsorption part that adsorbs to a treatment surface, a cup-shaped nozzle cover, a frame that supports the nozzle cover and the adsorption part, a nozzle that is arranged within the nozzle cover and sprays a treatment liquid onto the treatment surface, a driver that is arranged on the frame and rolls in contact with the treatment surface to cause the frame to travel relative to the treatment surface, and a treatment end marker that is arranged on the frame, extends along the traveling direction of the driver, protrudes from the nozzle cover, and indicates the positions of both ends of the spraying range of the nozzle when it travels in the traveling direction.

[0005] The treatment surface is, for example, a wall surface. The wall surface extends in the vertical direction. The wall surface is, for example, a steel wall or a reinforced concrete wall. The wall surface includes a ship's hull, particularly a ship's side. The treatment surface may be a horizontal surface.

[0006] The jet treatment device may be remotely controlled. The suction unit is, for example, a permanent magnet or a suction pad. The suction pad is connected to a suction device for suction. The suction device for suction may be disposed outside the jet treatment device. The frame may have a hanging hook, whereby the jet treatment device is hung via a rope.

[0007] The nozzle may be arranged so as to be able to swing, and in this case, the processing end mark indicates the swing width of the nozzle.

[0008] The drive body may be, for example, a wheeled vehicle or a tracked vehicle. The jet treatment device may have a drive source connected to the drive body and driving the drive body. The drive source may be, for example, an electric motor or a hydraulic motor.

[0009] The nozzle cover may have a sliding pad. The sliding pad closes a gap between the nozzle cover and the processing surface. The nozzle cover may be connected to a liquid suction device. The liquid suction device may be disposed outside the jet processing device.

[0010] The processing end marker may be, for example, triangular or trapezoidal. A trapezoidal processing end marker may extend over the entire width of the processing width. A bar-shaped processing end marker may be, for example, round or square. The processing end marker is preferably marked in a color complementary to the color of the processing surface. The entire surface and tip of the processing end marker may be marked in the opposite color to the processing surface. The processing end marker may be marked in different colors along the length. The processing end marker may be detachable from the frame. The processing end marker may be supported rotatably on the frame. Effect of the Invention

[0011] According to the present invention, it is possible to reduce overlap between a portion that has already been processed and a portion to be processed next. [Brief description of the drawings]

[0013] <Embodiment 1> As shown in Figs. 1 to 5, the jet processing device 10 of this embodiment includes a nozzle cover 13, a frame 11, a suction port 43, a sliding pad 41, a nozzle motor 31, an arm 33, a nozzle 35, a drive motor 23, two pairs of wheels (drive bodies) 25, an adsorption unit 27, a processing end marker 51, and a base 55. The jet processing device 10 performs water jet processing on a planar processing surface 1. The processing surface 1 is a magnetic body and extends in the vertical direction. The processing surface 1 is installed at an angle of, for example, 70 degrees to 110 degrees from the horizontal. The nozzle 35 rotates or swings around a rotation shaft 32. The radially outward side as viewed from the rotation shaft 32 is referred to as the outside. The direction toward the rotation shaft 32 is referred to as the inside. The jet processing device 10 is suspended by a rope 7 (see Fig. 5) and remotely operated by an operator.

[0014] The frame 11 has a pair of side plates 21, an inner beam 15, and an outer beam 17. The frame 11 supports the nozzle cover 13, the wheels 25, and the drive motor 23. The side plates 21 are arranged on both sides of the frame 11. The side plates 21 extend perpendicular to the processing surface 1. The inner beam 15 connects the side plates 21 to each other. Two or more inner beams 15 may be arranged. The outer beam 17 connects the side plates 21 to each other. The outer beam 17 is arranged outside the inner beam 15. The outer beam 17 does not need to contact the nozzle cover 13. The outer beam 17 may have a hanging hook 19. The jet processing device 10 is hung by the hanging hook 19. The hanging hook 19 may be arranged at both ends of a single outer beam 17.

[0015] Two wheels 25 are arranged on the outer sides of each side plate 21. The wheels 25 are rotatably supported on the side plate 21. The wheels 25 are connected to a drive motor 23 via a chain 24. The jet treatment device 10 travels on the treatment surface 1 by the wheels 25. The jet treatment device 10 mainly travels in a travel direction 61.

[0016] The suction unit 27 is disposed on the outside of the wheel 25. The suction unit 27 is a magnet. The magnet is, for example, a permanent magnet or an electromagnet. The suction unit 27 holds the jet treatment device 10 on the treatment surface 1. The suction unit 27 may be a suction pad.

[0017] The nozzle cover 13 is shaped like a hollow bowl. The nozzle cover 13 is fixed to the inner beam 15. The nozzle cover 13 is placed on the processing surface 1 so as to cover the nozzle 35. The nozzle cover 13 prevents the processing liquid 39 from scattering. A suspension (not shown) may be disposed between the inner beam 15 and the nozzle cover 13. The suspension absorbs undulations of the processing surface 1. The nozzle cover 13 may be included in the frame 11 .

[0018] The sliding pad 41 closes the gap between the nozzle cover 13 and the processing surface 1. The sliding pad 41 is annular and surrounds the outer edge of the nozzle cover 13. The sliding pad 41 may be biased toward the processing surface 1. The sliding pad 41 is made of a flexible material. The sliding pad 41 is, for example, rubber or synthetic resin.

[0019] The nozzle motor 31 is disposed in the center of the nozzle cover 13. The nozzle motor 31 is fixed to the outer surface of the nozzle cover 13. The nozzle motor 31 has a rotating shaft 32. The rotating shaft 32 is hollow. The rotating shaft 32 is connected to an arm 33. The processing liquid 39 is supplied to the nozzle motor 31, passes through the inside of the rotating shaft 32, and is supplied to the arm 33.

[0020] The arm 33 is rotated about a rotation shaft 32 by the nozzle motor 31. The arm 33 is linear and extends in the radial direction. The arm 33 is disposed closer to the processing surface 1 than the nozzle motor 31. The nozzle 35 is disposed on the arm 33 and faces the processing surface 1. The nozzles 35 are arranged in a radial direction. The nozzle 35 sprays the processing liquid 39 toward the processing surface 1. The number of nozzles 35 may be one. The arm 33 may have a plurality of arms extending from the rotation shaft 32. The arm 33 may also be capable of swinging.

[0021] The suction port 43 is disposed in the nozzle cover 13. The suction port 43 protrudes from the nozzle cover 13. A suction hose 65 is connected to the suction port 43. The suction hose 65 is connected to a liquid suction device 67 disposed externally.

[0022] The base 55 is disposed on the nozzle cover 13. The base 55 replaceably supports the processing end marker 51. The support 53 fixes the processing end marker 51 to the base 55.

[0023] The processing end marker 51 indicates both ends of the spray range 37 of the nozzle 35 in the traveling direction 61. The processing end marker 51 is arranged on both the left and right sides in the traveling direction 61. The spray range 37 is the rotation diameter of the nozzle 35 arranged on the outermost side. The processing end marker 51 protrudes from the side peripheral surface of the nozzle cover 13. The processing end marker 51 is rod-shaped. The rod-shaped processing end marker 51 extends along the traveling direction 61. The processing end marker 51 may be arranged only in front of the traveling direction 61 of the wheel 25. Preferably, the processing end marker 51 is arranged in front and rear of the traveling direction 61 of the wheel 25. The processing end marker 51 may be made of an elastic body so as to bend when it comes into contact with the processing surface 1. Preferably, the processing end marker 51 has a surface hardness lower than that of the processing surface 1. Preferably, the processing end marker 51 is marked in a color opposite to the color of the processing surface 1. The processing end marker 51 may be marked in different colors for different portions. For example, the tip of the processing end marker 51 is marked in a first color 57, the middle portion in a second color 58, and the base portion in a third color 59. The processing end marker 51 may be made of a retroreflective material. The processing end marker 51 may have a light emitter (not shown) and may emit light. The light emitter may be lit or flashing.

[0024] The treatment process by the jet treatment device 10 will be described with reference to Fig. 5. The jet treatment device 10 is suspended by a rope 7. The rope 7 is hung on a hanging hook 19. The rope 7 is wound up and let out in synchronization with the travel of the jet treatment device 10. The jet treatment device 10 adheres to the treatment surface 1 and travels on the treatment surface 1 by means of wheels 25. The travel direction 61 is the up and down direction. A pressure-resistant hose 63 supplies the treatment liquid 39 to the nozzle 35. The nozzle 35 sprays the treatment liquid 39. The jet of the treatment liquid 39 removes paint and dirt from the treatment surface 1. The sprayed treatment liquid 39 is collected from a suction hose 65.

[0025] The jet processing device 10 reciprocates in the vertical direction. This exposes the material of the treatment surface 1 in an oval range. The surface that has been water jet processed is called the treated surface 3. The boundary between the treatment surface 1 and the treated surface 3 is called the boundary line 5. The operator slides the jet processing device 10 sideways when it reaches the top or bottom of the treatment range. The operator controls the position of the jet treatment device 10 so that the processing end marker 51 coincides with the boundary line 5. Next, the operator moves the jet treatment device 10 so that the processing end marker 51 coincides with the boundary line 5. This prevents the spray ranges 37 of the treatment liquid 39 from overlapping, and promotes a reduction in the operation time.

[0026] <Embodiment 2> 6, the jet processing device 110 of this embodiment has a processing end mark 151 and a base 155. The other configurations of the jet processing device 110 are the same as those of the jet processing device 10 of the first embodiment.

[0027] The base 155 is disposed on the outer beam 17 of the frame 11 and supports the processing end marker 151. The processing end marker 151 is triangular with a pointed tip. When viewed in the travel direction 61, the tips of the processing end marker 151 indicate both ends of the spray range 37. The processing end marker 151 is marked in a color opposite to that of the processing surface 1 to improve visibility. The processing end marker 151 may be made of an elastic body. The processing end marker 151 may be disposed at both the front and rear of the travel direction 61.

[0028] <Embodiment 3> 7, the jet processing device 210 of this embodiment has a sign plate 254 and a base 255. The other configurations of the jet processing device 210 are the same as those of the jet processing device 10 of the first embodiment.

[0029] The base 255 is disposed on the frame 11 and supports the sign board 254 . The sign plate 254 extends across the entire width of the spraying range 37. The sign plate 254 is trapezoidal in shape with the shorter side facing away from the nozzle cover 13. The intersection of the shorter side and the hypotenuse of the sign plate 254 forms the processing end marker 251. When viewed in the travel direction 61, the processing end marker 251 coincides with both ends of the spraying range 37. The sign plates 254 are disposed at the front and rear of the travel direction 61.

[0030] <Embodiment 4> 8, the jet processing device 310 of this embodiment has a base 355, a rotating joint 60, and a processing end marker 351. The rotating joint 60 has a pin 356 and a support 353. The other configurations of the jet processing device 310 are the same as those of the jet processing device 10 of the first embodiment.

[0031] The base 355 is disposed on the frame 11 and supports the pin 356. The pin 356 has a circular cross section. The pin 356 protrudes in a direction perpendicular to the travel direction 61. The support 353 can swing around the pin 356 as an axis. The support 353 supports the processing end marker 351. An elastic ring 353b is disposed at the interface between the pin 356 and the support 353. The elastic ring 353b functions as a friction body. A friction force acts on the support 353 to the extent that it does not rotate naturally. When no external force is applied, the processing end marker 351 maintains a constant posture relative to the pin 356. The processing end marker 351 may be made of an elastic body so that it can be bent when it comes into contact with the processing surface 1.

[0032] When using the jet processing device 310, the positioning accuracy can be improved by bringing the tip of the processing end marker 351 close to the processing surface 1. When the processing end marker 351 comes into contact with the processing surface 1, the processing end marker 351 may swing relative to the pin 356. When the jet treatment device 310 is not in use, the processing end marker 351 may be arranged to face inward. In this embodiment, the jet treatment device 310 can be stored compactly without removing the processing end marker 351. The processing end marker 351 on the right side of Fig. 8 is in a state of protruding outward. The processing end marker 351 on the left side is in a state of facing inward.
