Description

Technical Field

[0001] The present invention relates to the technical field of marine ship design and construction, and in particular to a high-efficiency shuttle tanker shaft rudder system lighting integrated installation device and a use method thereof. Background Art

[0002] As the demand for crude oil is increasing, the market demand for shuttle tankers, a type of ship that can automatically locate at sea and easily dock with floating production storage and offloading vessels, is increasing. As a type of ship with an automatic positioning system, the shuttle tanker has a very high configuration of propulsion system and control system. The propeller blades are variable pitch propellers and the rudder blades are flap rudders. For this type of shipbuilding, the shaft rudder system requires high technical requirements for the installation of the stern tube, stern shaft, and rudder blades, with many processes, high difficulty coefficient, and high labor intensity.

[0003] At present, a Chinese patent with the authorization announcement number CN220076642U discloses a reference tooling for installing lighting for a ship's shaft rudder system, which has a frame-type bracket, a platform is arranged on the top of the bracket, one side of the frame-type bracket is vertically arranged relative to the ground, and the other side is inclined relative to the ground. A target platform is fixed on the top and inside of the frame-type bracket, and the target platform is parallel to the ground. A rectangular first channel steel is welded on the target platform, and the first channel steel is vertically fixed to the edge of the target platform. A first circular hole is opened on the first channel steel, and the first circular hole is 1500mm away from the target platform. The telescope is set at the first circular hole. A second channel steel is welded and fixed to the bottom of the first channel steel. The second channel steel is located outside the bracket and is arranged perpendicular to the first channel steel. The second channel steel has a second circular hole.

[0004] The above existing technical solutions have the following defects: only one working platform is used for lighting, and the installation of the stern tube, stern shaft, and rudder blade requires special devices to complete, and the tooling needs to be replaced constantly. There are many toolings, the tooling cost is high, and the workload of constantly replacing the tooling is greater, and a large number of gantry cranes are required to cooperate. There is a lack of a device that can meet these functions at the same time. Summary of the invention

[0005] The purpose of the present invention is to provide a high-efficiency shuttle tanker shaft rudder system lighting integrated installation device and use method to solve the problems existing in the above-mentioned prior art.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A high-efficiency shuttle tanker shaft rudder system lighting integrated installation device, including slide rails, working platform, winch, pulley, jacking device and support frame, the slide rails are two in total, the two slide rails are parallel and spaced apart, the spacing distance is set according to the spacing of the moving wheels at the bottom of the working platform, the slide rails are slidably installed with the working platform, the working platform is mainly driven by the winch and the pulley, the winch and the pulley are symmetrically arranged, the winding and unwinding of the winch will control the movement of the working platform at both ends of the slide rails, the working platform is divided into an upper frame and a lower frame, and the support frame is divided into an upper support frame and a lower support frame, the lower support frame is fixedly installed at the four corners of the top of the lower frame, the top of the lower support frame is provided with a jacking device, the jacking device is the oil top, the top of the oil top is fixedly installed with the upper support frame, the upper support frame at the front end of the working platform Rollers are also provided on the upper part, and the rollers are inclined toward the center line of the working platform. This is to be able to accommodate cylindrical workpieces. The lower support frame, the oil top and the upper support frame are vertical as a whole. The upper support frame is connected to the left side of the top of the oil top by adjusting bolts. While fixing, the left and right positions of the upper support frame can also be adjusted to accommodate workpieces of different sizes. A number of support plates are provided on the working platform. These support plates are used to place workpieces or to enable operators to stand on the working platform to work. A lifting hoist is also provided on the top of the support plate of the lower frame. There are four lifting hoists in total, and their main purpose is to fix the workpiece. Sometimes they can also play a certain traction role. The top and bottom of the upper frame and the bottom of the lower frame are respectively provided with a first support plate, a second support plate and a third support plate.

[0008] By adopting the above technical scheme, the working platform itself includes two upper and lower platforms, and more working platforms can be integrated to replace the original cumbersome working process and tooling. At the same time, the lifting device can adjust the height of the workpiece. Whether it is the rudder blade, stern tube or variable pitch propeller shaft, it needs to be fixed by a lifting hoist. And because the main weight of the variable pitch propeller shaft is all on the middle track during its walking on the upper platform, the two rows of frames on the upper platform are also added with herringbone braces. At the same time, since there is no need to design a variety of tooling and cumbersome disassembly and installation procedures, relying on the integration of multiple modules on a working platform, the labor intensity is reduced, the difficulty of the operation is greatly reduced, and the installation efficiency of the shaft rudder system lighting, stern tube, stern shaft and rudder blade is effectively improved.

[0009] In a further embodiment, the sliding rail includes two types of rails, a limiting rail and a flat iron rail. Limiting rails are set at both ends of the flat iron rail. The limiting rail and the flat iron rail are both set from front to rear, and a limiting angle steel is set on one side of the limiting rail. The limiting rails at both ends of the flat iron rail on the left have their limiting angle steels set on the left, while the limiting rails at both ends of the flat iron rail on the right have their limiting angle steels set on the right.

[0010] In a further embodiment, support rods are provided at the bottom ends of the left and right sides of the working platform, and guide wheels are rotatably installed on the support rods. The lengths of these support rods are consistent, and the angles are perpendicular to the working platform. At the same time, the spacing between the guide wheels is equal. The main function of this guide wheel is to prevent the working platform from running off the track. At the same time, the guide wheel can also cooperate with the limiting track, so that the working platform can only move back and forth on the part of the slide rail that is not limited by the limiting angle steel, and will not easily fall off the slide rail.

[0011] In a further embodiment, an inclined ladder is provided on the right side of the working platform. The inclined ladder is mainly a climbing device, which is used to facilitate the workers to reach the top of the working platform and complete the lighting work there. A railing is provided on the inclined ladder. Since the environment at the bottom of the dock is relatively dark, it is easy to cause accidents when climbing up when the lighting is not fully set. The railing can effectively avoid such accidents. At the same time, the railing is detachably installed on it. When movement interference occurs for some reason, the railing can also be removed. Another method is to hinge the railing on the inclined ladder and use a chain or the like to secure it. The flange plates are fixed in place, and the support plates are composed of flange plates and H-shaped steel. Most of the flange plates are bolted to the H-shaped steel and cannot be disassembled. The flange plates at the center line of the rudder system are detachable. This is to facilitate the lighting operation of the rudder system. Flower steel plates are welded on the flange plates. The patterns on the surface of the flower steel plates can greatly increase the friction. On the one hand, it is convenient for the placement of tools such as light targets and total stations. On the other hand, it is also convenient for operators to avoid slipping. The support plate at the bottom of the lower stand is flat as a whole, so that the moving wheel group at the bottom of the entire working platform is also evenly stressed.

[0012] In a further embodiment, a plurality of lifting ears are provided on the top of the first support plate, and the main function of these lifting ears is for lifting. The first support plate and the upper frame are fixedly connected, and the upper frame and the lower frame are fixed by bolts, some of which are fixed by welding. This makes it possible to lift the entire work platform by lifting the first support plate, and in subsequent operation processes, when the upper frame needs to be removed, the removed upper frame can also be lifted away from the top of the lower frame conveniently and quickly through the lifting ears.

[0013] In a further embodiment, the entire jacking system includes multiple jacking devices, a hydraulic pump, a distributor and multiple synchronization valves. Through the distributor, the hydraulic pump can control the jacking device at the front end and the jacking device at the rear end respectively, and through the synchronization valve, the hydraulic pump can control all the jacking devices at the front end and the rear end at the same time.

[0014] In a further embodiment, the lighting operation generally includes setting up lighting facilities, setting up light targets, and setting up a total station, calibrating different rudder system base points according to the laser beam emitted by the weight transfer, setting laser reflecting iron sheets on the rudder system base points, and ensuring that the bull's-eyes of each light target are located on the same straight line through a hypothetical telescope. The main equipment used to determine the consistency of the bull's-eyes of the rudder system centerline in the entire process is installed on the top of the working platform, and the top of the working platform is also mainly used for lighting operations.

[0015] In a further embodiment, after the lighting operation is completed, multiple subsequent operations can be started, including the installation of the stern tube, the installation of the variable pitch propeller shaft, epoxy pouring, stern tube drilling and other operations.

[0016] In a further embodiment, when the rudder blade is finally installed, since the shape of the rudder blade is difficult to fix and cannot be simply fixed by a lifting hoist, it is necessary to use additional steel pipe welding to fix the rudder blade and the lower frame. The number of steel pipes to be welded and the position of the welding need to be calculated based on the change of the formula. Only when the safety factor meets the preset value can the transportation officially begin. Otherwise, more steel pipes need to be welded and calculations need to be performed.

In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this specification, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0024] Embodiment 1:

[0025] like Figure 1 - Figure 3As shown, a high-efficiency shuttle tanker shaft rudder system lighting integrated installation device includes a dock bottom, a slide rail 1 is arranged at the dock bottom, the slide rail 1 includes a first flat iron rail and a second flat iron rail arranged in parallel at an interval, and the front sides of the first flat iron rail and the second flat iron rail are aligned, and the distance between the two flat iron rails is consistent with the spacing of the moving wheel groups at the bottom of the working platform 2, and the first limiting rail and the second limiting rail are respectively installed in the same direction on the front and rear sides of the first flat iron rail. Since the first flat iron rail is arranged on the left side of the second flat iron rail, the left side of the front end of the first limiting rail and the left side of the rear end of the second limiting rail are both arranged A first angle steel is arranged, and the function of the first angle steel is to limit the position, and a corresponding arrangement is also arranged on the second flat iron track symmetrically arranged on the right side along the bottom midline of the working platform 2. The second flat iron track is fixedly connected to the third limiting track, the fourth limiting track and the two second angle steels. The working platform 2 is slidably installed on the top of the slide rail 1, and a plurality of first support rods and a plurality of second support rods of the same length are respectively installed on the left side of the bottom end of the working platform 2 and the right side of the bottom end of the working platform 2, and each of the first support rods is installed with a first guide wheel, and each of the second support rods is installed with a second guide wheel, and the first guide wheel and the second guide wheel are installed on the left side of the bottom end of the working platform 2. The intervals between them are equal and consistent, and they are all used to assist the walking of the working platform 2 to avoid deviation during the movement. At the same time, the length of the first support rod does not exceed the length of the first angle steel, which makes the first angle steel and the second angle steel limit the moving distance of the working platform 2. An inclined ladder 9 is welded on the right side of the front end of the working platform 2. The function of the inclined ladder 9 is a climbing device. In order to facilitate the operators to quickly and safely climb the inclined ladder 9, a handrail is detachably installed on the right side of the top of the inclined ladder 9. When the movement trajectory may collide with lifting equipment, tooling, etc., the handrail can be removed from the inclined ladder 9. A plurality of chains are fixedly installed on the track, and the detachable railings are usually fixed by means of chains and buckles. The specific movement of the working platform 2 depends on the winch 3 and the pulley 4, which are respectively arranged at one end of the track and the other end of the track, and are arranged relatively to each other. When the winch 3 is winding, the working platform 2 can be moved away from the winch 3 through the opposite pulley 4. When the winch 3 is releasing the line, the working platform 2 can be moved toward the winch 3 through the opposite pulley 4. The overall moving distance and moving speed are safe and reliable, and there is no need for frequent lifting with lifting equipment, which greatly reduces the complexity of the construction.

[0026] like Figure 1 - Figure 3As shown, the working platform 2 includes an upper platform 21 and a lower platform 22. A first support plate 12 is fixedly installed on the top of the upper platform 21. The function of the first support plate 12 is to provide a working platform for completing the lighting operation. The first support plate 12 is composed of a plurality of H-shaped steels 121 and a plurality of flange panels 122. The two ends of the H-shaped steel 121 are respectively fixedly connected to the inner side of the top of the entire frame of the upper platform 21. These H-shaped steels 121 are welded along the center line direction of the shaft rudder system, and a special space is left in the middle to avoid the lighting wire. This space is called an avoidance groove. The flange panel 122 is bolted and fixed on the H-shaped steel 121. The flange panel 122 is not set at the avoidance groove, but the first flower steel plate 133 can be detachably installed. At the same time, a second flower steel plate 134 is welded and fixed to the top of the flange plate 122. The functions of the first flower steel plate 133 and the second flower steel plate 134 are to increase friction to prevent the operator from slipping during work. The second support plate 13 is fixedly installed at the bottom of the upper platform 21, and the third support plate 14 is fixedly installed at the bottom of the lower platform 22. The structures of the first support plate 12, the second support plate 13 and the third support plate 14 are consistent. The bottom of the upper platform 21 is fixedly connected to the top of the lower platform 22. When connected, it is first fixed by bolting with the connecting plate. After it is firmly fixed, the intersection part is welded. The welding is firm and reliable, and can support the lifting of the lifting equipment without separation. A plurality of lifting ears are evenly distributed on the top periphery of the first support plate 12 , multiple lifting ears are used to lift the work platform 2 onto the slide rail 1 as a whole. After the slide rail 1 is laid, the work platform 2 cannot be driven onto the slide rail 1 by itself, so light and heavy equipment is needed to lift it. Multiple lifting hoists 6 are arranged on the top of the third support plate 14, and the multiple lifting hoists 6 are used to fix the workpiece. A support module 5 is arranged on the third support plate 14. The support module 5 includes multiple lower support frames 52 and multiple upper support frames 51 with the same number as the lower support frames 52. Lower support frames 52 are arranged at the four corners of the top of the third support plate 14. A total of four lower support frames 52 are welded and fixed to the third support plate 14. A jacking device 7 is fixedly installed on the top of each lower support frame 52. The jacking device 7 is actually an oil jack, which relies on hydraulic pressure The hydraulic pump 10 is driven by the pump 10, and the hydraulic pump 10 is fixedly installed on one side of the top of the third support plate 14, and a distributor 11 is arranged beside the hydraulic pump 10. The distributor 11 is responsible for dividing the hydraulic oil output by the hydraulic pump 10 into two parts and distributing them to the oil top at the front end or the rear end. The distributor 11 is provided with a stop valve. When adjusting the front support frame, the stop valve of the rear support frame is closed. Conversely, when adjusting the rear support frame, the stop valve of the front support frame is turned off. In order to ensure that the oil top on the front support frame can be synchronously lifted, and the oil top on the rear support frame can be synchronously lifted, a first synchronous valve and a second synchronous valve are respectively installed behind the distributor 11. The distributor 11 is provided with a first liquid outlet and a second liquid outlet at intervals. The first liquid outlet is connected to the inlet of the first synchronous valve through a high-pressure pipeline.The second liquid outlet is communicated with the inlet of the second synchronous valve through a high-pressure pipeline, the outlet of the first synchronous valve is communicated with a plurality of jacking devices 7 at the front end of the working platform 2, and the outlet of the second synchronous valve is communicated with a plurality of jacking devices 7 at the rear end of the working platform 2. An upper support frame 51 is also vertically arranged on the jacking device 7, and the jacking device 7 is fixedly connected to the upper support frame 51 by a transversely arranged adjustment bolt, so that the spacing between the upper support frames 51 can be adjusted according to the different diameters of the workpieces to be carried. A plurality of avoidance holes corresponding to the positions of the upper support frames 51 are arranged on the first support plate 12 and the second support plate 13, and rollers 8 are arranged on the top of the upper support frame 51 at the front end of the working platform 2, and the rollers 8 are symmetrically arranged along the midline of the first support plate 12 from front to back, and the rollers 8 are all toward the first support The center line of the support plate 12 is inclined. Since the workpieces that the upper platform 21 needs to carry are all cylindrical, such as the stern tube and the variable pitch propeller shaft, the inclined roller 8 can well clamp and fix the workpiece. The roller 8 is made of copper, which can better protect the workpiece. The top of the first support plate 12 is provided with a slide groove from front to back, and a mobile platform is slidably installed in the slide groove. The mobile platform is used to provide a higher height for different types of operations. The mobile platform needs to be moved to avoid interference with the workpiece when carrying the stern tube or the variable pitch propeller shaft. Therefore, it can be moved to the maximum distance. In the processes such as epoxy pouring and stern tube drilling, the height provided by the mobile platform is required to complete the corresponding operation, which can save multiple procedures of tooling and many cumbersome lifting processes. ,

[0027] like Figure 1 - Figure 4 As shown, the steps include: S1, performing lighting operation on the top of the upper stage 21;

[0028] S2. Install the stern tube and the variable pitch propeller shaft in sequence, and perform epoxy pouring and stern tube drilling operations;

[0029] S21, after the lighting operation is completed, the working platform 2 is moved to the designated position by the winch 3, the stern tube is placed on the top of the upper support frame 51, and fixed with the hoist 6;

[0030] S22, the hoisting hoist 6 adjusts the lateral position of the stern tube, and the jacking device 7 adjusts the height of the stern tube. After the calibration is completed, the jacking device 7 is replaced by the supporting bolts;

[0031] S23, the working platform 2 moves and guides the stern tube to penetrate into the hole of the cast steel hole piece. When it is about to reach the stern position, the working platform 2 stops moving, removes the upper support frame 51 at the front end of the working platform 2, and continues to move until the stern tube is in place;

[0032] S24, slide the mobile platform to a suitable position, and the operator stands on the mobile platform to adjust the stern tube, epoxy pouring, stern tube drilling and other operations;

[0033] S25, after the stern tube operation is completed, the working platform 2 is moved to the designated position by the winch 3, the upper support frame 51 is reinstalled, the variable pitch propeller shaft is placed on the top of the upper support frame 51, and fixed with the hoist 6;

[0034] S26, the hoist 6 adjusts the lateral position of the variable pitch propeller shaft, and the jacking device 7 adjusts the height of the variable pitch propeller shaft to calibrate the position of the variable pitch propeller shaft. After the calibration is completed, the jacking device 7 is replaced with the support bolts;

[0035] S27, the working platform 2 moves and guides the variable pitch propeller shaft to penetrate into the hole of the stern tube. During the whole process, an operator needs to use a walkie-talkie to observe the moving state of the variable pitch propeller shaft at the front end of the stern tube and make timely adjustments to avoid damage.

[0036] S28, after the variable pitch propeller shaft is in place, install the stern seal, move the working platform 2 to the designated position by the winch 3, and remove the upper platform 21;

[0037] S3, calculating the safety of the rudder blade and the lower stand 22 after being combined;

[0038] S31, calculating the safety factor of the rudder blade against tipping according to the weight of the rudder blade, the width of the rudder blade, the mass of the rudder blade, the moving speed of the lower stand 22, the height of the center of gravity of the rudder blade and other data;

[0039] S32, if the safety factor is lower than the preset value, first calculate the height of the center of gravity after assembly, and then calculate the overall anti-dumping safety factor according to the overall center of gravity height, the weight of the rudder blade, the weight of the lower stand, the moving speed of the lower stand and other data; if the safety factor is higher than the preset value, start the transportation process;

[0040] S33, if the safety factor is lower than the preset value, the lower stand 22 is further welded to the rudder blade through a steel pipe for further reinforcement; if the safety factor is higher than the preset value, the transportation process is started;

[0041] S4, fixing the rudder blade on the top of the lower stand 22;

[0042] S5. Install the rudder blade.

[0043] In the above steps, the calculation formula for the anti-tilting of the rudder blade is: (g1 b / 2) / (m1 vl 1+fs l 1)>n;

[0044] Among them, g1 is the weight of the rudder blade, b is the width of the rudder blade, M1 is the mass of the rudder blade, v is the acceleration of the rudder blade during movement, l 1 is the height of the center of gravity of the rudder blade, f is the wind pressure, s is the wind-receiving area of ​​the rudder blade, and n is the safety factor. According to the basic parameters of the fully suspended rudder, g1 is taken as 274 tons, b is 9 meters, M1 is 274 tons, v is 0.5 meters per square second, l 1 is 5.4 meters, f is 0.1 MPa, s is 33.4 square meters, and n is 1.2;

[0045] After substitution, the safety factor is about 1.63, that is, the rudder blade will not tip over under the acceleration of the lower gantry 22 of 0.5 meters per square second. If the acceleration is increased to 1 meter per square second, the safety factor is 0.82, which is less than the preset safety factor of 1.2. Therefore, the appropriate acceleration of the lower gantry 22 can be calculated based on the safety factor.

[0046] After the rudder blade and the lower frame 22 are fixed by steel pipe welding, the overall anti-tilting coefficient needs to be calculated. Before the calculation, their overall height and the height of the center of gravity after the combination need to be known first;

[0047] In the above steps, L = (g1L1 + g2L2) / (g1 + g2);

[0048] Wherein, L is the height of the center of gravity after assembly, g1 is the weight of the rudder blade, g2 is the weight of the lower frame 22, L2 is the height of the center of gravity of the lower frame 22, and L1 is the height of the center of gravity after the rudder blade is installed on the lower frame 22. Similarly, g1 is 274 tons, g2 is 10 tons, L1 is 6.6 meters, and L2 is 0.7 meters;

[0049] After substituting, we can get that L is about 6.4 meters;

[0050] After obtaining the height of the center of gravity after reassembly, the overall anti-tipping calculation is performed;

[0051] In the above steps, [(g1+g2)B / 2] / [(m1+m2)vL+fsL]>nL;

[0052] Wherein, g1 is the weight of the rudder blade, g2 is the weight of the lower gantry 22, M1 is the mass of the rudder blade, M2 is the mass of the lower gantry 22, B is the sum of the maximum width of the rudder blade and the maximum width of the front side of the lower gantry 22, v is the acceleration of the rudder blade during movement, f is the wind pressure, s is the wind-receiving area of ​​the rudder blade, n is the safety factor, and g1 is 274 tons, g2 is 10 tons, B is 13.5 meters, M1 is 274 tons, M2 is 10 tons, V is 0.01 meters per square second, f is 1 megapascal, and s is 33.4 square meters;

[0053] After substitution, we can get 8.27>7.68. When the acceleration of the rudder blades during movement after assembly is 0.01 meters per square second, the overall device will not be at risk of tipping over. After confirming that the welding is secure, the device can be moved accordingly to complete the installation of the rudder blades.
