Description

[0002] Deep well cargo oil pumps (imported from abroad are generally supplied by MARFLEX, FRAMO, and WARTSILA, and require very high installation accuracy) are widely used in various types of oil and chemical ships. Because their products are arranged in cargo oil tanks, the overall length of the cargo pump is generally 10-20 meters. It is necessary to fix its support ring with multiple layers of intermediate supports and weld the intermediate supports to the trough bulkhead. The design of cargo oil pumps and intermediate supports requires comprehensive consideration of: manufacturer standards, cargo pump position (laser alignment), wave-shaped trough wall layout, large gangway on the main deck, T-plate and bulb flat steel structure on the main deck, cargo oil pipes, and electrical cable layout.

DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be described in detail below by way of embodiments with reference to the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0035] The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, B exists alone, and A and B exist at the same time. The term " / and" in this article describes another type of association object relationship, indicating that there can be two relationships. For example, A / and B can mean: A exists alone, and A and B exist alone. In addition, the character " / " in this article generally indicates that the previous and next associated objects are in an "or" relationship.

[0036] according to Figure 1-Figure 12 As shown, a deep well cargo oil pump system includes a cargo pump support and an oil level lifting member, wherein the cargo pump support is arranged on the oil tank 1 and the cargo pump 2, and the oil level lifting member is arranged on the oil tank 1. The cargo pump support includes a layered support member 24, and the layered support member 24 connects the oil extraction pipe 7 of the cargo pump 2 to the bulkhead of the oil tank 1 in layers. The oil extraction pipe 7 is vertically inserted into the oil tank 1, so that the cargo pump 2 can pump oil out of the oil tank 1.

[0037] The layered support member 24 includes an ear plate 3, a support connection block 4 and a support ring 5. The ear plate 3 is arranged on the grooved bulkhead 6 of the oil tank 1, one end of the support connection block 4 is connected to the ear plate 3, the support ring 5 is set and limited outside the oil extraction pipe 7, and the support ring 5 is connected to the other end of the support connection block 4 to support and limit the oil extraction pipe 7 to prevent the oil extraction pipe 7 from shaking when pumping oil.

[0038] Furthermore, the ear plate 3 is L-shaped or I-shaped. When the two ends of the ear plate 3 are welded to the grooved bulkhead 6, the lengths of the two ends of the ear plate 3 can be freely selected according to the angle shape of the grooved bulkhead 6 at the construction site, so as to meet the welding requirements in time, reduce stress concentration, and improve the installation adaptability and installation efficiency of the ear plate 3. One end of the support connection block 4 is detachably connected to the ear plate 3 by a first bolt. Furthermore, the mounting hole on the ear plate 3 cooperates with the first bolt, and the mounting hole is completed by laser cutting after positioning at the construction site, so as to prevent the mounting hole prefabricated on the ear plate 3 from having a large error when the support connection block 4 is detachably connected, and the connection operation cannot be completed quickly. After the support ring 5 is fastened and sleeved outside the pumping pipe 7, it is connected to the other end of the support connection block 4 by a second bolt.

[0039] Two ear plates 3 are provided, and the two ear plates 3 are spaced apart on the grooved bulkhead 6 on the same plane. Two supporting connection blocks 4 are provided, and the two supporting connection blocks 4 correspond to the two ear plates 3 one by one, and the two supporting connection blocks 4 are both connected to the supporting ring 5. The supporting ring 5 is in an eight-shaped shape through the two supporting connection blocks 4 to support and limit the oil pumping pipe 7.

[0040] As an option, four sets of the layered support members 24 are provided, and the four sets of the layered support members 24 are used to fasten, support and limit the oil pumping pipe 7 at equal vertical intervals to improve the stability of the cargo pump 2 during the oil pumping process, and improve the oil pumping efficiency and safety of the oil pumping process.

[0041] It should be noted that our company has improved the conventional door-type bracket type and directly adopted the combination type of eight-shaped angle steel support + L-shaped ear plate 3 (or I-shaped), which not only saves a lot of support materials, but also meets the design requirements of the manufacturer. The most important thing is that it reduces at least half of the engineering workload and technical difficulty for on-site installation and alignment. It has now been fully promoted to all subsequent oil and chemical ships 15000DWT / 3600DWT special coating / 6000DWT / 6600DWT / 10600DWT special coating / 7850DWT... and has formed the company's internal production design standard.

[0042] The specific effects in production include:

[0043] 1) Save material costs and reduce the folding material of AIS316L stainless steel (or duplex stainless steel)

[0044] 2) Save production costs, optimize design forms, reduce intermediate manufacturing welding volume and working hours (zero welding is achieved in the new bracket design);

[0045] 3) Save construction costs, reduce the workload of on-site hoisting and alignment, greatly improve installation and positioning efficiency, and optimize lighting tooling design and materials;

[0046] 4) Optimize the design to help reduce the empty ship weight (based on a 3600DWT chemical tanker)

[0047] Conventional single bracket material L100X100X10 is about 1100+1140+441+1473+486=4.64 meters, weighing about 72.8KG

[0048] Improved single bracket material: single bracket L100X100X10 is about 1342+787=2.12 meters and weighs about 33.43KG.

[0049] On average, each ship has 7 cargo holds and 14 cargo pumps, which can save angle steel L100X100X10, about 14*2*(4.64-2.12)=65.52 meters, and reduce weight by 0.99T;

[0050] 5) The length of the L-shaped ear plate 3 (or I-shaped) of the bracket can be freely adjusted according to the corner of the grooved bulkhead 6 to avoid the stress area (100MM from the corner);

[0051] 6) The bolt holes of the L-shaped ear plate 3 (or I-shaped) of the bracket can be positioned and punched after laser alignment, which effectively solves the trouble of readjusting the bracket due to alignment deviation;

[0052] 7) The length of the L-shaped ear plate 3 can be freely adjusted without being affected by the specific arrangement of the cargo pump (the cargo oil pipeline on the main deck, the gangway, and the oil suction well under the cargo hold are arranged according to strict specifications and cannot be adjusted at will).

[0053] The oil level lifting member includes an oil level lifting support member, an oil level power lifting member and an oil level lifting limit member.

The support leg 8 is cylindrical, and one end of the support leg 8 is vertically fixed on the bottom surface of the oil tank 1. There are six support legs 8, and the six support legs 8 are evenly distributed around the circumference of the vertical projection of the oil pumping pipe 7. The radius of the circle formed by the six support legs 8 is three times greater than the radius of the oil pumping pipe 7, so as to increase the oil surface area lifted by the oil level lifting member and meet the suction requirements of the oil pumping pipe 7. The support connection slider 9 is annular, and the inner wall of the support connection slider 9 is fixedly connected and sleeved on the six support legs 8 at the same time to improve the support stability of the six support legs 8 and provide support for the oil level power lifting member.

[0055] The oil level power lifting member includes an oil level lifting power member and an oil level gathering lifting member, wherein the oil level lifting power member is arranged on the oil level lifting support member, and the oil level gathering lifting member is arranged on the oil level lifting power member.

[0057] The power part includes a motor 12 and a gear 13. The motor 12 is fixedly arranged on the bottom surface of the oil tank 1. The gear 13 is fixedly arranged on the rotating shaft of the motor 12, and the gear 13 is meshed with the ring gear 11. When the motor 12 is started, the ring gear 11 will be driven to rotate through the gear 13. Furthermore, a gear housing is provided at the meshing point between the gear 13 and the ring gear 11. As an option, the motor 12 is a waterproof, pressure-resistant and explosion-proof motor, and the motor 12 is covered with a sealed protective shell to meet the requirements of use in oil.

[0058] The oil level gathering lifting member includes an oil level gathering arm 14 and a transmission stabilizing rod 15. The oil level gathering arm 14 is in the shape of a spiral line plate. One end of the oil level gathering arm 14 is horizontally fixedly arranged on the side wall of the power transmission pipe 10, and the lower side of the oil level gathering arm 14 is slidably fitted with the bottom surface of the oil tank 1. At the same time, the upper and lower widths of the oil level gathering arm 14 are greater than the distance from the bottom end of the power transmission pipe 10 to the bottom surface of the oil tank 1. Further, four oil level gathering arms 14 are provided, and the four oil level gathering arms 14 are evenly distributed around the circumference of the power transmission pipe 10. One end of the transmission stabilizer bar 15 is horizontally fixed on the power transmission tube 10, and the other end of the transmission stabilizer bar 15 is horizontally fixed on the other end of the oil level gathering arm 14, so as to improve the circumferential rotation of the oil level gathering arm 14 when the power transmission tube 10 rotates, thereby gathering the oil within the range of the oil level gathering arm 14 into the power transmission tube 10, and raising the oil level by cooperating with the oil level lifting limiter, so as to facilitate the oil to be pumped out by the cargo pump 2. The four transmission stabilizer bars 15 correspond to the four oil level gathering arms 14 one by one. Furthermore, a universal ball 16 is provided on the lower side of the oil level gathering arm 14, so that the oil level gathering arm 14 is in sliding contact with the bottom surface of the oil tank 1 through the universal ball 16, so as to further improve the stability of the oil level gathering arm 14 during the rotation process of the power transmission tube 10 and improve the efficiency of gathering the oil into the power transmission tube 10.

[0059] The oil level lifting limiter includes a folding power member and a limit folding member. The folding power member is arranged on the oil level lifting support member, and the limit folding member is arranged on the folding power member. The folding power member includes a folding guide shaft 17, a folding power tube 18 and a magnetic coil. The length of the folding guide shaft 17 is greater than the distance from the bottom port of the pumping pipe 7 to the bottom surface of the oil tank 1. One end of the folding guide shaft 17 is vertically arranged on the other end of the support leg 8, and the axis of the folding guide shaft 17 coincides with the axis of the support leg 8. The folding power tube 18 is tubular, and the inner diameter of the folding power tube 18 is not less than the diameter of the folding guide shaft 17.

Further, the sliding block on the inner wall of the folding power tube 18 cooperates with the sliding groove on the side wall of the folding guide shaft 17, and the top of the sliding groove is not through the top of the folding guide shaft 17, so as to limit the folding power tube 18 axially and prevent the folding power tube 18 from sliding out of the other end of the folding guide shaft 17. The magnetic coil is fixedly embedded in the spiral groove on the inner wall of the folding power tube 18 .

[0060] When direct current is passed into the magnetic coil to generate a magnetic field, the folding power tube 18 will be driven to slide up and down along the folding guide shaft 17, thereby providing power for the unfolding and folding of the limit folding member. Furthermore, six sets of folding power members are provided, and the six sets of folding power members correspond to the six support legs 8 one by one. It should be noted that since the switching switch for controlling the direction of the direct current passed into the magnetic coil is located outside the oil tank 1, and no sparks are generated during the process of passing the current into the magnetic coil, the magnetic coil is highly safe when used in the oil tank 1 and meets the use requirements.

[0061] The position-limiting folding member includes an annular slide rail 19, a soft oil pipe 20 and a top transmission ring 21.

When a positive direct current is passed into the magnetic coil to generate a magnetic field, the folding power tube 18 will be pushed to slide upward on the folding guide shaft 17, and then the other end of the soft oil pipe 20 will be driven to expand upward to form a cylindrical shape through the top transmission ring 21. The oil entering the power transmission tube 10 is continuously pushed in by the oil surface gathering arm 14, so that the oil surface continues to rise in the soft oil pipe 20, and then submerges the bottom port of the pumping pipe 7, so that the pumping pipe 7 can further discharge oil outward and reduce the amount of residual oil at the bottom of the oil tank 1. Furthermore, a support hoop 23 is fixedly connected to the soft oil pipe 20, and multiple support hoops 23 are evenly distributed along the axial direction on the soft oil pipe 20 to improve the radial bearing capacity of the soft oil pipe 20 after expansion, and to facilitate the uniform folding of the soft oil pipe 20.
