Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of equipment for ship maintenance, especially a superhigh pressure horizontal bottom derusting operation vehicle for ship maintenance. BACKGROUND

[0002] In recent years, under the pressure of market environment, major ship owner companies increasingly pursue the economy of ship navigation, and the number of ships with hull painting changed to high-efficiency antifouling paint and silicone antifouling paint has generally increased. However, the prerequisite for changing the original paint is that the surface of the steel plate must reach the Sa2.0 standard, so the number of ships with full scraping of the hull in ship repair yards has also been increasing year by year. Each time a full-scraped ship is docked, a large amount of manpower, vehicles, and materials are required.

[0003] The traditional process uses an electric derusting disc for derusting. The derusting disc can be fixed on the operating bar of a high-altitude vehicle for use on the vertical surface of the hull and a small part of the area with large curvature, or it can be installed on a hand-held support for use on the horizontal surface such as the deck and the bottom plate. The work efficiency is low, and the operator is required to have high skills. In addition, under the background of actively advocating environmentally friendly derusting and green painting in various fields, ship repair yards purchase wall-climbing robots for maintenance and sandblasting operations. The robot must use the waterline and the straight bottom bow and stern lines as the key construction areas for superhigh pressure water full scraping. The flat bottom is compensated by increasing the number of sandblasting gun operators to make up for the difference in progress between the flat bottom and the waterline and the straight bottom. However, due to the influence of the flat dock pier, the wall-climbing robot may crash if the operation is not careful, which not only causes damage to the equipment, but also affects the construction progress.

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model.

[0016] like Figs. 1-2 As shown, this utility model includes a rust removal mechanism 1, a support column 2, an adjustment mechanism, and a frame 3. The rust removal mechanism 1 is located on top of the support column 2. The adjustment mechanism includes two sets of parallel connecting frames 4 and an adjustment component. The two ends of the connecting frames 4 are hinged to the support column 2 and the frame 3, respectively. The bottom end of the adjustment component is connected to the frame 3, and the top end of the adjustment component is connected to the middle of the connecting frames 4. The adjustment mechanism adjusts the angle between the connecting frames 4 and the frame 3. By adjusting the angle of the connecting frames 4, the height of the support column 2 can be raised or lowered, thereby pressing the rust removal mechanism 1 onto the horizontal bottom of the ship.

[0017] To ensure stable lifting and lowering of the adjustment assembly, the adjustment assembly includes an adjustment screw 5, an adjustment block 6, two connecting blocks 7, and an adjustment nut 8. The connecting block 7 has a through hole in the middle. The connecting block 7 is hinged to the middle of the connecting frame 4 and the frame 3 via hinges. The connecting blocks 7 are located at both ends of the adjustment screw 5. The left connecting block 7 is fixedly connected to the adjustment nut 8. The adjustment screw 5 passes through the through hole of the adjustment nut 8 and the connecting block 7. A stop block 17 is fixedly connected to the right end of the adjustment screw 5. The stop block 17 is located to the left of the right connecting block 7. The adjustment block 6 is located at the right end of the adjustment screw 5 and abuts against the connecting block 7. Rotating the adjusting block 6 can adjust the length of the screw screw into the adjusting nut 8, thereby adjusting the distance between the two connecting blocks 7. Since the connecting frame 4, the support column 2 and the adjusting screw 5 form a triangle in space, and the support is in a fixed position, adjusting the length of the adjusting screw screw into the adjusting nut 8 will cause the angle of the connecting frame 4 to change, thereby raising or lowering the support column 2 in the vertical direction, adjusting the height of the rust removal mechanism 1 to meet the actual working height requirements.

[0018] To ensure the stability of the support pillars and improve the stability of the rust removal process, the connecting frame 4 is configured as an I-beam, and there are two pillars 2, which are respectively hinged to the front and rear ends of the connecting frame 4.

[0019] In order to press the rust removal mechanism 1 stably on the horizontal bottom of the ship, the bottom of the support column 2 is further provided with a pressing assembly, which comprises a supporting cylinder 9 and a pressing spring 10, the supporting cylinder 9 is provided with a longitudinal sliding cavity, the bottom end of the support column 2 is inserted into the sliding cavity, and the pressing spring 10 is arranged at the bottom of the sliding cavity and supports the support column 2. The connecting frame 4 and the outer wall of the supporting cylinder 9 are hinged through a hinge, and the height of the support column can be adjusted to press the rust removal mechanism 1 on the ship bottom, at this time, the pressing spring 10 is in a compressed state, and the contact between the rust removal mechanism 1 and the ship bottom is ensured.

[0020] Preferably, the rust removal mechanism 1 comprises a water supply pipe 11, an ultrahigh-pressure water rust removal head 12 and a rust removal cavity 13, and the ultrahigh-pressure water rust removal head 12 is located in the rust removal cavity 13. The support column is hinged to the center of the bottom of the rust removal cavity 13, which can make the ultrahigh-pressure water rust removal head slightly inclined with the angle of the ship bottom during the rust removal process, so that the ultrahigh-pressure water rust removal head is in close contact with the ship bottom, and the rust removal effect is improved. The support column pushes the rust removal cavity, so that the ultrahigh-pressure water rust removal head is pressed on the ship bottom. The water supply pipe 11 sprays cooling water towards the ultrahigh-pressure water rust removal head 12, so as to cool and cool during the rust removal process. The bottom of the rust removal cavity 13 is provided with a waste discharge channel 14, the frame 3 is provided with a roller 15 below, and the frame 3 is provided with a push hand 16 on the side. During the rust removal process, the debris enters the rust removal cavity 13, and then the cooling water flows into the rust removal cavity 13 and is discharged from the waste discharge channel 14 for treatment.

[0021] Before use, the utility model is moved to a suitable working position, then the adjusting block 6 is rotated, the ultrahigh-pressure water rust removal head 12 is pressed on the ship bottom, then the ultrahigh-pressure water rust removal head 12 is operated, the ultrahigh-pressure water rust removal head 12 can be moved by pushing the push hand 16, and after rust removal, the anti-collision adjusting block can lower the ultrahigh-pressure water rust removal head 12.

[0022] The above only describes the preferred embodiments of the utility model, and it should be pointed out that, for ordinary skilled persons in the technical field, some improvements and modifications can be made without departing from the technical principles of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
