Description
Technical Field
The invention relates to the field of rust removal and corrosion prevention of ship surfaces, in particular to a rust removal device for a ship surface.
Background
Before launching a new ship, the anticorrosion work of the ship body assembly can be completed before the ship body is assembled. However, after the entire ship is launched into the sea and navigated in the ocean for a period of time, the hull surfaces are highly susceptible to corrosion due to both electrochemical corrosion and marine corrosion. Even if the isolation corrosion prevention and the electrochemical corrosion prevention are adopted, the occurrence of the event cannot be prevented. When the corrosion phenomenon occurs, the surface of the ship body is required to be repaired in time, namely surface rust removal and secondary corrosion prevention treatment. However, because of the large volume of the ship (especially for marine facilities such as various large transport ships and offshore oil drilling platforms), when the surface of the ship body is corroded, the surface rust removal and secondary coating work can only be carried out on the dock, and the large-area ship surface rust removal work has extremely high requirements on the rust removal efficiency and the rust removal quality. On the one hand, the overall rust removal treatment needs to be carried out on the surface of the whole ship within a few days. On the other hand, the surface of the hull after rust removal needs to reach certain rust removal quality and surface roughness (GB 8923 Sa 2.5, GB/T13288 medium grade) so as to meet the adhesive force requirement of a coating material.
At present, the main hull surface rust removal methods can be divided into the following three categories: 1. derusting by an artificial ship; 2. chemical ship rust removal; 3. and (5) derusting the mechanical ship. The manual ship rust removal method has the longest application time and the widest application range. The manual ship rust removal takes manpower as main labor force, and the rust removal worker is provided with rust removal tools such as a hammer, a scraper knife, a scraper, a steel wire brush and the like. However, due to low efficiency and poor rust removal quality of artificial rust removal, artificial ship rust removal is replaced by mechanical ship rust removal and chemical ship rust removal in the early century. The chemical ship rust removal is a ship rust removal method which removes a rust layer on the surface of a ship by utilizing double decomposition reaction of acid and metal oxide to generate soluble metal ion salt. Compared with manual ship rust removal, the chemical rust removal has higher cost and higher requirement on the operation environment, and generally can only be operated in a workshop and is not suitable for dock operation. In addition, in the chemical rust removal process, the steel which is not corroded yet is also corroded by acid, and irreversible damage is easily caused to ships. And the waste water generated by chemical rust removal belongs to dangerous waste, the treatment difficulty and the treatment cost of the dangerous waste are extremely high, the requirement of environmental protection is not met, and the sustainable development of enterprises is not facilitated.
Compared with manual ship rust removal and chemical ship rust removal, mechanical ship rust removal gradually occupies the ship rust removal market by virtue of the advantages of high efficiency, low price and the like. The existing mechanical ship rust removal mainly comprises sand blasting rust removal and ultrahigh pressure water jet rust removal. Compressed air is used as power for sand blasting and rust removal, spray materials (garnet sand, copper ore sand, quartz sand, carborundum, iron sand, Hainan sand and the like) are sprayed to the rusty ship surface at a high speed after high-speed spraying is formed, so that a rust layer falls off from the ship surface under the high-speed impact of the spray materials, and the aim of removing rust on the ship surface is fulfilled. Compared with manual rust removal, the sand blasting rust removal is simple and convenient, and the rust removal efficiency is high. However, the method has high energy consumption, great dust and noise pollution and intensive labor. Therefore, the use of sand blasting has been gradually prohibited since the beginning of the century. Compared with sand blasting and rust removal, the ultrahigh pressure water jet rust removal is a novel environment-friendly and economic ship rust removal method. And (3) utilizing a high-pressure water generating system to enable the water pressure to reach 1500bar, and utilizing the ultrahigh kinetic energy of the high-pressure water to enable the corrosion layer to fall off in the collision process with the jet water. The ultra-high pressure water jet rust removal does not generate dust pollution, and can carry out rust removal treatment on special parts (such as valves and the like). In addition, the method can effectively remove soluble salt on the surface of the ship so as to reduce the influence of the coating on the adhesion of the ship surface. However, the ultra-high pressure water jet rust removal also has certain limitations. On one hand, the Young modulus of water is very small, so that the surface of the treated steel cannot reach high enough roughness (equal to or larger than middle grade) no matter how large the water pressure is, the chelation degree of secondary spraying is not good enough, and the coating is easy to peel, bubble and fall off; on the other hand, flash rust is very likely to occur in steel products treated with high-pressure water, and the treatment of flash rust often depends on a complicated and expensive aqueous flash rust inhibitor. On one hand, the use of the water-based flash rust inhibitor can increase the rust removal cost, and on the other hand, the water-based flash rust inhibitor can greatly reduce the adhesion between the subsequently coated oil paint and the surface of the ship. Most importantly, the ultra-high pressure water rust removal has large demand on fresh water resources. According to the search and analysis of the prior art documents, when the ultra-high pressure water jet method is used for rust removal, the water consumption per minute reaches 37-120L, and when a ship with the surface area of 10 ten thousand square meters is treated, the water consumption can reach 7500-12000 tons, so that a great deal of fresh water resource waste and fresh water resource pollution are caused, and the current green development and low-carbon development concepts are not met.
By integrating the ship rust removal method and the rust removal difficulty, the development of the high-efficiency rust removal device which does not need to utilize water resources, can effectively reduce energy consumption, does not have dust pollution, does not need sewage treatment and has low labor cost is particularly important in the ship surface rust removal operation process. In fact, shipyards are rigidly equipped with aerial lift trucks for marine operations and high-power suction filtration devices (or industrial vacuum cleaners). By utilizing the existing equipment configuration of a shipyard, a new rust removal device is developed, and the problems of construction cost, environmental pollution, wastewater treatment and the like can be effectively reduced while the rust removal efficiency and effect are considered.
The high-altitude operation vehicle equipped in the shipyard is generally used for high-altitude operations such as manual sand blasting, rust removal, surface painting, surface repair and the like. Because constructors need to carry out high-altitude operation in the operation platform of the high-altitude operation vehicle, in order to prevent the danger of personnel and equipment caused by collision between the high-altitude operation vehicle and a ship body in the operation process, a control platform of the high-altitude operation vehicle is often carried on the operation platform of the high-altitude operation vehicle. The operator can stand in the operation platform to operate the high-altitude vehicle to move front, back, up, down, left and right. The load carrying capacity of such aerial lift trucks is generally low due to the need to carry the operator. Generally, the maximum load bearing limit of an overhead working truck in a dock is about 250kg, and after operators and constructors of the overhead working truck are removed, the residual load bearing capacity is only about 100kg, and the safe load is even lower than 50 kg. Therefore, if a novel rust removing device capable of utilizing the existing high-altitude operation vehicle in a shipyard needs to be developed, the quality of the developed rust removing device needs to be light, and therefore safety of personnel and equipment in the rust removing process is guaranteed. Light derusting equipment cannot provide enough impact force (or pressure, torque and the like) to meet the derusting requirement, for example, the mass of a 1500bar high-pressure water generating system generally reaches over 200kg, and other equipment lower than the mass cannot reach the high pressure of 1500 bar. Therefore, it is necessary to develop a light-weight, high-power rust removing apparatus capable of simultaneously ensuring safety and rust removing quality. The high-power suction filtration equipment of a shipyard is generally used for sewage discharge, cargo transfer and the like of watertight compartments, cargo holds and the like in the cabins of the shipyard. The pumping filtration equipment has high operating power, can generate extremely high negative pressure (about 30kPa), is suitable for pumping filtration of liquid and is also suitable for pumping of gas and granular solids.
According to the existing equipment in the dock, whether a novel mechanical rust removing device can be developed or not can be used for realizing the omnibearing treatment on the surface of the whole ship body by utilizing the high-altitude operation capacity of a high-altitude vehicle; on the other hand, the negative pressure suction filtration function of the existing suction filtration equipment is utilized to collect rust, paint chips and the like generated in the rust removal process. The equipment can meet the requirement of rust removal treatment on the surface of a ship body, can also meet the technical requirements of no water resource utilization, effective reduction of energy consumption, no dust pollution, no sewage treatment, low labor cost and high efficiency rust removal. However, because the surface of the ship body has a certain curvature, the working surface of the rust removing device is always changed at any time, and therefore the rust removing device also needs to meet the requirement of working under various planes with small curvature. Meanwhile, the surface curvature often causes poor fitting degree between the rust removing equipment and the working plane, and rust powder and paint chips generated in the rust removing process may fall onto the surface of a ship body or the inside of a dock to cause pollution. The developed equipment must ensure high waste residue collection effect.
By combining the ship rust removal method and the ship factory prior art, in the ship surface rust removal operation process, the development of the high-efficiency rust removal device which can directly utilize the existing high-altitude operation vehicle and suction filtration equipment (or industrial dust collector) of the ship factory, does not need to utilize water resources, can effectively reduce energy consumption, does not have dust pollution, does not need sewage treatment and has low labor cost is particularly important.

When the rust removing work is performed, the moving mechanism 5 is positioned between the surface of the ship and the rust removing device mounting body 2.
Fig. 3 shows a schematic structural view of the fixing mechanism 1 used in the rust removing device 100 of the present invention. As shown in fig. 3, the fixing mechanism 1 is attached to the top of the rust removing device mounting body 2 (directly above as shown in fig. 2), and includes: an operating arm 6, an operating arm spring hook 7, a fixed spring 9 and a universal ball base 8. The fixing mechanism 1 is arranged on one side of the derusting device and the carrying main body 2 far away from the surface of the ship (the derusting mechanism is arranged on one side of the carrying main body 2 near the surface of the ship), and is connected with the carrying main body 2 through an operating arm spring hook 7, a carrying main body spring hook 14 and eight fixing springs 9 which are distributed in a centrosymmetric mode. One ends of eight fixed springs 9 which are distributed in a central symmetry mode are mounted on an operation arm spring hook 7 on an operation arm 6, and the other ends of the eight fixed springs are mounted on a main body mounting spring hook 14 right above a rust removing device mounting main body 2. The eight fixed springs 9 distributed in the central symmetry can provide a certain degree of freedom of rotation around the center for the carrying main body 2 of the derusting device, so that the derusting device can adjust the direction at a small angle when moving on a curved ship surface, the fit degree between the derusting device and the ship surface is enhanced, the eight springs in the central symmetry are the same, the length of the springs and the included angle between the springs and the operating arm 6 can be determined according to actual needs, and the projection length of the springs on the axis of the operating arm 6 is substantially equal to the vertical distance between the spring hook 7 of the operating arm and the top of the carrying main body 2 or is slightly longer.
As shown in fig. 4 and 5, the operation arm 6 is composed of an operation arm support 10 and a universal ball 11. The gimbaled ball 11 is located at the end of the operating arm support 10. The arm support 10 is mainly used for connecting a working platform of an aerial work vehicle in a dock, and can be strongly fixed with the working platform through an expansion sleeve, a fastening bolt and the like. When an operator controls the overhead working truck to move, the operating arm support 10 can transmit the movement kinetic energy of the overhead working truck to the derusting device, so that the derusting device can be controlled to move forwards, backwards, upwards, downwards, leftwards and rightwards on the surface of a ship. The universal ball 11 is nested in the universal ball carrying port 13 of the universal ball base 8, and the universal ball base fixing base 12 of the universal ball base 8 is connected with the upper surface of the rust removing device carrying main body 2 through bolts, so that the rust removing device carrying main body 2 is prevented from falling off from the fixing mechanism 1, and danger is caused. The ball 11 can be rotated three-dimensionally at a small angle through the ball mounting port 13. The universal ball 11 can make the derusting device carry on the main part 2 and carry on the small angle ground adjustment direction on the surface of the ship under the pressure effect that the high altitude construction car provided, and the extension and the compression of eight centrosymmetric distribution's fixed spring 9 cooperate, the derusting device can better laminate with the ship surface of partial bending to improve the laminating degree of derusting device and ship surface. In the present invention, the improvement in fit includes, but is not limited to, one or more of the following: universal ball 11, fixed spring 9, U-shaped piece and hydraulic platform.
As shown in fig. 1, 2, 6, 7 and 8, the overall rust removing device mounting body 2 is a rectangular parallelepiped structure, and eight centrally symmetrically distributed mounting body spring hooks 14 are mounted on the top of the body for connecting with the fixing springs 9 on the fixing mechanism 1. The rust removing mechanism 3 is provided inside the rust removing device carrying body 2 and is exposed through the bottom of the rust removing device carrying body 2, so that the rust removing mechanism 3 is in direct contact with the surface of the ship and rust removal is possible. A circular waste residue blocking brush 49 is also arranged at the bottom of the rust removing device carrying main body 2 around the exposed rust removing mechanism 3. The waste residue blocking brush 49 is composed of hundreds of vertically arranged polyethylene terephthalate fibers and a fiber fixing substrate. On one hand, the polyethylene terephthalate fiber can generate small-amplitude deformation under the pressure action of the overhead working truck, so that the rust removing device can be better attached to the surface of the ship. On the other hand, hundreds of vertically arranged polyethylene terephthalate fibers can obstruct waste residues generated in the derusting operation, prevent the waste residues from falling out of the derusting device, and improve the recovery capacity of the derusting waste residues. The waste residue blocking brush 49 includes, but is not limited to, a vertically arranged fiber group structure, a solid hole structure, a fiber mesh structure, a flocculent structure, and the like, and all components having the air-permeable function and the waste residue blocking function belong to the application range of the waste residue blocking brush 49.
As shown in fig. 6, 7, 8, 9 and 10, the front end of the rust removing device carrying body 2 does not carry any relevant equipment, and a suction filtration equipment interface 39 connected with the negative pressure suction filtration device, a power supply interface 48 and a lead fixing hole 51 are left right in the middle of the rear end. One end of the suction filtration equipment interface 39 close to the rust removal device carrying main body 2 is connected with a waste residue recovery mechanism 4 carried in the rust removal device, and the other end is connected with a negative pressure suction filtration device in a shipyard through a corrugated pipe and used for recovering solid wastes generated in the rust removal operation process. One end of the power supply interface 48 close to the rust removing device carrying main body 2 is connected with the internal rust removing motor 17, and the other end is connected with a power supply facility through a lead to provide power input for the rust removing device. The wire fixing hole 51 is used for fixing relevant wires inside the rust removing device carrying main body 2 so as to prevent the wires from loosening and damaging equipment due to vibration and movement in the rust removing operation or transportation process.
As shown in fig. 6, 11, and 12, two sets of moving mechanisms 5 are connected to both sides of the rust removing device mounting body 2. The moving mechanism 5 and the side of the rust removing device carrying main body 2 are connected with the riveting bolt through the angle iron-main body connecting hole 46. The four groups of moving mechanisms 5 can realize that the derusting device can freely move on the surface of the ship body by 360 degrees, effectively avoid the problems of derusting dead angles and the like, and improve the derusting efficiency.
As shown in fig. 13, 14, and 22, the rust removing mechanism 3 is provided inside the rust removing device mounting body 2, and the detailed structure thereof is shown in fig. 13 and 14. The derusting mechanism 3 mainly comprises a power part and a derusting unit. The power part consists of a plurality of small derusting motors 17 with the same specification and model, at least two motors are arranged, preferably 3 motors, 4 motors, 5 motors, 6 motors or 8 motors are arranged uniformly and at intervals along the circumferential direction of the rotor bevel gear; the number of the rust removing motors is 4, and the motors are uniformly arranged along the circumferential direction of the rotor bevel gear at intervals of 90 degrees. The rust removing unit is a bowl-shaped wire brush assembly 22 composed of a bowl-shaped wire brush 32 and the like. Four small-sized rust removing motors 17 are positioned at the uppermost end of the rust removing mechanism 3 and fixed on a motor fixing base 20. The motor fixing base 20 is fixed above the insulating cylinder 21 by a zigzag iron 27. Inside the isolation cylinder 21 and right below the motor fixing base 20 is a bowl-shaped wire brush assembly 22.
As shown in fig. 13, 14, 15, and 22, the four rust removing motors 17 in the rust removing mechanism 3 are uniformly distributed in four directions of the motor fixing base 20, and the motor rotors 53 thereof are all directed toward the center of the motor fixing base 20. The rust removing motor 17 is fixed above the motor fixing base 20 through a plurality of motor fixing holes 23 (in fig. 15, each rust removing motor is connected to the motor fixing base through four holes as an example) and a motor base 55. The torque of the motor provides enough torque for the bowl-shaped wire brush assembly 22 through the torque summarizing and regulating device to meet the requirement of rust removal work. In the example of the invention, the torque summing and control device comprises a transmission gear 19, a rotor bevel gear 18 and an output shaft; the drive gear 19 is installed at the front end of the motor rotor 53 of the rust removing motor 17 and engaged with the rotor bevel gear 18, which cooperates to converge the torques of all the rust removing motors 17 and adjust the total torque direction to a direction parallel to the working surface. In actual use, the torque summing and control device has a plurality of variants and equivalent implementation methods, including but not limited to rotor bevel gear engagement, helical gear engagement, disk type gear engagement, and belt drive.
In the present invention, the rotor bevel gear 18 is merged with the drive gear 19 and is provided to the bowl-shaped wire brush assembly 22 after being adjusted in direction. The total torque merged by the rotor bevel gear 18 and the transmission gear 19 is parallel to the motor fixing base 20, and can provide a torsion force parallel to the surface of the ship for the bowl-shaped wire brush assembly 22, namely, the merged total torque enables the bowl-shaped wire brush assembly 22 to rotate around an axis perpendicular to the motor fixing base 20. The total torque after the rotor bevel gear 18 and the transmission gear 19 are merged is higher than 6 kg.m, so that the requirement of rust removal is met. The rust removal motor 17 adopted by the invention is a high-speed light motor. The high speed is to meet the requirement of efficient rust removal, and the light weight is to reduce the weight of the rust removal device as a whole. The single high-speed or light motor can not meet the requirement of the rust removing motor of the invention on rust removal of the rust removing mechanism, so that a plurality of rust removing motors are required to be connected in parallel to realize torsion convergence so as to meet the requirement of the invention. For this reason, when the number of the examples is 4, the no-load rotating speed of the derusting motor used by the invention is higher than 10000rpm/min, and the single torque is higher than 1.5 kg.m. In the example, the circuit connection of the four rust removal motors 17 is parallel connection, so that the voltages at two ends of each motor and the passing currents are completely the same, and the matching purpose is achieved. The rotating speeds of the four rust removing motors 17 can be manually controlled by a single resistance adjusting knob regulator, and the controllable rotating speed is between 0rpm and 10000 rpm/min.

The number of the bowl-shaped steel wire brushes 32 can be determined according to the actual requirement and the size of the steel wire brush fixing substrate, and is at least 3, can be 3-12, and is preferably 7, 8 and 9. The number of examples of the present invention is 9. The bowl-shaped wire brush 32 is located right below the bowl-shaped wire brush fixing disc 31 and is connected with the fixing clamping plate 33 through the bowl-shaped wire brush fixing hole 35 and the bowl-shaped wire brush fixing bolt 37. The bowl-shaped wire brush fixing disc 31 and the fixing splint 33 are used for fixing the bowl-shaped wire brush 32, so that the rust removing area is increased. The bowl-shaped steel wire brush fixing holes 35 are uniformly distributed on the bowl-shaped steel wire brush fixing disc 31, 3-12, preferably 7, 8 and 9, and are distributed in a centrosymmetric manner by taking the circle center of the bowl-shaped steel wire brush fixing disc 31 as the center, so that the requirement of angular momentum isotropy is improved, the rotation stability is improved, the abrasion degree is reduced, and the service life of the device is prolonged. The bowl-shaped steel wire brush 32 is fixed with a special steel wire 36 with the diameter less than 1mm and the length more than 3cm and is used for removing rust on the surface of the ship body. The diameter of the special steel wire 36 is less than 1mm, so that the surface of the derusted ship can reach the roughness meeting the standard, namely the surface roughness of the derusted ship by the special steel wire 36 is higher than the GB/T13288 medium-grade requirement. The length of the special steel wire 36 is higher than 3cm, and the diameter is lower than 1mm, so that the joint degree of the rust removal unit and the surface of the ship is better under the pressure of the overhead working truck, and the service life of the rust removal unit can be further prolonged. The surface of the special steel wire 36 is plated with copper, so that the wear resistance is strong, and the continuous rust removal work requirement of more than twelve hours can be met. The special steel wires 36 have even distribution density, and the number of the special steel wires in each square centimeter range is higher than thirty.
In the present invention, the bowl-shaped wire brush fixing disk 31 is a disk shape with a steel centrosymmetry, the center thereof has a base connection hole 56, and the edge thereof has a plurality of bowl-shaped wire brush fixing holes 35 distributed centrosymmetrically. Two crescent bowl-shaped wire brush limiting holes 34 are arranged on two sides of the bowl-shaped wire brush fixing hole 35. The bowl-shaped wire brush limiting hole 34 and the bowl-shaped wire brush fixing hole 35 are centrosymmetric, so that the requirement of angular momentum isotropy can be improved, the rotation stability of the derusting mechanism 3 can be improved, the abrasion degree of a rotating part can be reduced, and the service life of the device can be prolonged. The bowl-shaped wire brush assembly 22 includes but is not limited to a bowl-shaped wire brush 32 and a bowl-shaped wire brush fixing plate 31, and all the wire brush assemblies adopting the steel wire and steel wire bearing base structure belong to the scope of the bowl-shaped wire brush assembly 22.

The top of the isolation cylinder 21 is connected with the motor fixing base 20 through the Z-shaped iron 27 and the base fixing hole 29. In one aspect, a spacer 21 may be used to carry the motor fixing base 20 and the descaling motor 17. On the other hand, the isolation cylinder 21 can be used for isolating the rust removal motor 17 and the bowl-shaped wire brush assembly 22 in the rust removal device carrying body 2, so as to prevent iron rust, paint waste residues, water and the like generated in the rust removal process from entering the rust removal device carrying body 2 to influence the normal work of the work pieces such as the rust removal motor 17 and the like. 3-7 suction ports 26, preferably 5, are reserved on the side surface of the isolation cylinder 21, and are used for installing a corrugated pipe-suction port adapter 41 and connecting to the waste residue recovery mechanism 4.

The other end of the bellows 40 is connected to the suction filtration device port 39. The bellows-suction filter adapter 41 is used for sucking off waste residues, dust, etc. generated by the bowl-shaped wire brush assembly 22 during the rust removal process. The bus of the corrugated pipe 40 is corrugated, so that the corrugated pipe has good bending performance on one hand, and the corrugated pipe shell can bear higher internal and external air pressure difference on the other hand, thereby effectively avoiding the phenomenon that the conveying pipe is flattened due to the internal and external air pressure difference in the negative pressure suction filtration process. One end of the suction filtration equipment interface 39 close to the outer side of the rust removal device can be connected with the existing suction filtration equipment in a shipyard and is used for recovering iron rust, paint waste residues and the like generated in the rust removal operation.
