Description

Technical Field

[0001] The invention belongs to the field of shipboard cabin installation, and in particular relates to a method for installing and positioning a shipboard B-type cabin by using a three-dimensional adjustment machine. Background Art

[0002] Type B tanks are tank-shaped devices used by liquefied gas carriers to store cryogenic liquefied gas. When the Type B tank is hoisted into the hull for installation, a large number of saddle structures need to be aligned and matched between the Type B tank and the hull, and the matching accuracy is high. In addition, accurate alignment is required in the three directions of ship length, ship width and ship height. Since the hoisting equipment has limited ability to adjust the spatial position of the Type B tank, it is difficult to accurately align the Type B tank saddle with the hull saddle. This will cause the gap between the Type B tank saddle and the hull saddle to be greater than or less than the design requirement, making it impossible to install and fill the connecting parts between the Type B tank saddle and the hull saddle - the laminated wood and the epoxy resin for bonding the laminated wood according to the design requirements.

[0003] The three-dimensional adjustment machine is a professional equipment that uses vertical cylinders, longitudinal cylinders, and transverse cylinders as core components, combines electromechanical and hydraulic, and is used for the installation and positioning of large components. It has the characteristics of strong load capacity, high positioning accuracy, simple operation, and high adjustment efficiency. The load capacity of a single three-dimensional adjustment machine is hundreds of tons, and the positioning accuracy can reach 0.1mm. Multiple three-dimensional adjustment machines can be connected in series and in parallel to the central control console through communication lines, and are centrally controlled by the central control console. The three-dimensional adjustment machine has pressure and displacement sensors, which can feed back the adjustment status to the central control console in real time. The vertical cylinders, longitudinal cylinders, and transverse cylinders of multiple three-dimensional adjustment machines can be independently moved and linked in three directions of height, length, and width in any combination to achieve full spatial position adjustment of large components. For example, the 180-ton PLC-controlled three-dimensional adjustment machine of Shanghai Neste Hydraulic Equipment Co., Ltd. has a product model: MCA3 / 1-180-250-100-RC. However, it is difficult to use the three-dimensional adjustment machine to position and adjust the B-type cabin.

[0004] The installation and positioning method of the ship-borne B-type tank in the prior art is: when the B-type tank is installed and positioned, the position of the B-type tank in the height direction of the ship is adjusted and controlled by multiple hydraulic cylinders arranged at the bottom of the B-type tank. The installation and positioning method has the following problems:

[0005] 1. The position of the B-type cabin in the length and width of the ship cannot be accurately controlled, and the lifting equipment needs to be adjusted multiple times. Due to the low adjustment accuracy of the lifting equipment, it is often necessary to cut or replace the longitudinal laminated wood and the transverse laminated wood to cooperate with the installation of the B-type cabin; laminated wood is usually not available in stock and needs to be customized, and it is expensive and has a long production cycle. Therefore, this method will greatly extend the construction period and cause a serious increase in production costs.

[0006] 2. The strong structural positions of the B-type cabin and the hull are occupied by the B-type cabin saddle and the hull saddle. The strength of the B-type cabin structure and the hull structure around the position where the three-dimensional adjustment machine can be arranged and work is relatively weak, which does not meet the strength requirements of the three-dimensional adjustment machine for the surrounding structure under load working conditions.

[0007] 3. The three-dimensional adjustment machine is large in size, while the internal space of the hull where the B-type cabin is installed is small and there are many saddles. It is necessary not only to consider the rationality of the layout and number of the three-dimensional adjustment machine, but also to consider structural interference problems, equipment connections, and personnel and material passages.

[0008] 4. The three-dimensional adjustment machine needs to be withdrawn from the hull after use. At this time, the B-type cabin has been installed and positioned. It is impossible to use lifting equipment to transfer the three-dimensional adjustment machine out of the hull. It can only be transported by manpower. The weight of the three-dimensional adjustment machine is about 1 ton, which makes transportation difficult. Summary of the invention

[0009] The present invention aims to solve the problems that the installation and positioning method of the ship-borne B-type cabin in the prior art is complicated, inefficient, and cannot meet the requirements in terms of precision. It is often necessary to cut or replace the longitudinal laminated wood and the transverse laminated wood to match the installation of the B-type cabin, the construction period is long, and the production cost is seriously increased. A method for installing and positioning the ship-borne B-type cabin using a three-dimensional adjustment machine is provided, which includes the following steps:

[0010] S1: Arrange the position of the three-dimensional adjustment machine in the hull and install it;

[0011] S2: Use lifting equipment to lift the B-type tank vertically into the hull;

[0012] S3: The first hovering of the hoisting device is used to adjust the transverse and longitudinal positions of the B-type cabin;

[0013] S4: The lifting equipment continues to lift the B-type tank vertically into the hull;

[0014] S5: The second hoisting stop is used to adjust the transverse and longitudinal positions of the B-type cabin again;

[0015] S6: After the hoisting equipment continues to hoist the B-type cabin to the installation position, the B-type cabin is installed by operating the three-dimensional adjustment machine;

[0016] S7: Move the three-dimensional adjustment machine out of the hull.

[0017] According to the above-mentioned method for installing and positioning a ship-borne type B cabin using a three-dimensional adjustment machine, in step S1: the three-dimensional adjustment machine includes a machine body, a vertical cylinder, a longitudinal cylinder, and a transverse cylinder arranged on the side wall of the machine body; displacement and pressure sensors are arranged inside the machine body; a base is arranged at the lower part of the vertical cylinder; a hydraulic pump station is arranged at the bottom of the three-dimensional adjustment machine body; height-adjustable universal wheels are arranged on both sides of the three-dimensional adjustment machine body, and when the three-dimensional adjustment machine is moved, the universal wheels are extended and the base leaves the ground; when the three-dimensional adjustment machine is working, the universal wheels are retracted and the base contacts the ground.

[0018] According to the method for high-precision installation and positioning of a ship-borne B-type cabin using a three-dimensional adjustment machine, in step S1: a B-type cabin vertical saddle is provided on the B-type cabin, and a main vertical plate and a panel are provided on the B-type cabin vertical saddle; the main vertical plate is extended to form a new main vertical plate, and the middle area of ​​the panel is extended to form a new panel; a plurality of reinforcing brackets are provided between the new main vertical plate and the new panel; the new main vertical plate, the new panel, and the reinforcing bracket are combined to form a support point for the three-dimensional adjustment machine to work;

[0019] The structure of the hull at the location where the three-dimensional adjustment machine is arranged is strengthened, reinforcing ribs are arranged between the inner bottom longitudinal girder and the T-shaped steel at the lower part of the vertical saddle of the B-type tank, and reinforcing flat irons are arranged between the angle steels, so that the structure of the hull at the location where the three-dimensional adjustment machine is arranged can withstand the pressure of the three-dimensional adjustment machine in the working state;

[0020] The open area in the middle of the bottom of the Type B tank is used as a passage for personnel and materials.

[0021] According to the above-mentioned method for high-precision installation and positioning of ship-borne B-type tanks using a three-dimensional adjustment machine, the load-bearing capacity of the vertical cylinder of the three-dimensional adjustment machine is 1.5 times the weight of the B-type tank area it bears;

[0022] The horizontal pushing capacity of the longitudinal cylinder and the transverse cylinder is:

[0023] [Weight of Type B cabin / number of three-dimensional adjustment machines] × friction coefficient × 1.5;

[0024] At the same time: [the height of the three-dimensional adjustment machine + the height of the joist] < the distance from the support point to the inner bottom plane;

[0025] [Height of 3D adjustment machine + height of joist + stroke of vertical cylinder] > distance from support point to inner bottom plane;

[0026] The stroke of the longitudinal cylinder and the transverse cylinder is greater than the positioning accuracy range of the B-type cabin lifting equipment.

[0027] According to the above-mentioned method for installing and positioning a ship-borne type B cabin using a three-dimensional adjustment machine, in step S1: the three-dimensional adjustment machines are arranged on both sides of the vertical saddle of the type B cabin at the four corners of the bottom of the type B cabin and the middle positions of the left and right sides, and two three-dimensional adjustment machines are arranged near each vertical saddle of the type B cabin, and the three-dimensional adjustment machines are connected to the central control console at the rear side of the type B cabin along the outer edge of the type B cabin using a communication bus;

[0028] The steps of positioning the three-dimensional adjustment machine are as follows:

[0029] S1.1: The base is pressed on top of the hull reinforcement ribs;

[0030] S1.2: Install a joist above the vertical cylinders of the two three-dimensional adjustment machines;

[0031] S1.3: The upper part of the middle position of the joist corresponds to the support point on the vertical saddle of the Type B tank.

[0032] According to the above-mentioned method for installing and positioning a ship-borne type B cabin using a three-dimensional adjustment machine, in step S3: when the distance from the lower surface of the vertical laminated wood of the type B cabin to the upper surface of the vertical saddle of the hull is C1, where: 800mm≤C1≤1200mm, the type B cabin stops falling, and at this time the lower surface of the vertical laminated wood is higher than the upper surface of the support beam; during the first hovering of the lifting equipment, the lateral position and longitudinal position of the type B cabin are adjusted so that each saddle of the type B cabin is aligned with each saddle of the hull.

[0033] According to the above-mentioned method for installing and positioning a ship-borne type B cabin using a three-dimensional adjustment machine, in step S5: the lifting equipment is made to drop the type B cabin, and the distance from the lower surface of the vertical laminated wood to the upper surface of the vertical saddle of the hull is C2: wherein: when: 50mm≤C2≤150mm, the type B cabin stops falling again, and the lifting equipment hovers for the second time. At this time, the longitudinal saddle of the type B cabin enters between the longitudinal saddles of the hull, and the transverse saddle of the type B cabin enters between the transverse saddles of the hull.

[0034] According to the above-mentioned method for installing and positioning a ship-borne B-type tank using a three-dimensional adjustment machine, in step S6: the step of installing the B-type tank by operating the three-dimensional adjustment machine includes:

[0035] S6.1: Control the three-dimensional adjustment machine through the central control console to lift the vertical cylinder and push it to the supporting point through the joist;

[0036] S6.2: The hoisting equipment places the weight of the B-type cabin on the three-dimensional adjustment machine in multiple times and gradually. The three-dimensional adjustment machine cooperates with the hoisting equipment for dynamic adjustment to evenly distribute the force of each three-dimensional adjustment machine until the three-dimensional adjustment machine fully bears the weight of the B-type cabin;

[0037] S6.3: Measure the clearance L between all B-type tank longitudinal saddles and the hull longitudinal saddles; measure the clearance B between all B-type tank transverse saddles and the hull transverse saddles;

[0038] S6.4: The longitudinal cylinders and transverse cylinders of all three-dimensional adjustment machines are controlled through the central control console. The longitudinal cylinders and transverse cylinders push the vertical cylinders, and the vertical cylinders drive the B-type cabin to move longitudinally and transversely, thereby adjusting the gaps L and B;

[0039] The displacement data of the vertical cylinder is transmitted to the central console through the displacement and pressure sensors and displayed. The operator repeatedly operates the central console based on the displayed data to adjust all gaps L and B. The displacement accuracy of the longitudinal and transverse cylinders is 0.1mm, which can achieve high-precision adjustment of the gaps L and B, and finally make the gap L meet the requirements for longitudinal laminated wood installation and the gap B meet the requirements for transverse laminated wood installation.

[0040] Control all vertical cylinders to fall back synchronously, so that the B-type cabin is close to the installation position;

[0041] Measure the gap H between the lower surface of all vertical laminated wood and the surface of the white steel plate on the vertical saddle of the hull;

[0042] The vertical cylinders of all three-dimensional adjustment machines are controlled through the central console to adjust the gap H. The displacement accuracy of the vertical cylinder is 0.1mm, which can achieve high-precision adjustment of the gap H to meet the epoxy resin thickness requirements. At the same time, the B-type cabin is adjusted to ensure that the positioning height and levelness of the B-type cabin meet the installation requirements.

[0043] After the above adjustments are completed, measure the gap L, gap B and gap H again to check whether the gap L, gap B and gap H meet the installation and positioning requirements of type B cabin. If not, continue to use the three-dimensional adjustment machine to adjust until the requirements are met;

[0044] S6.5: All three-dimensional adjustment machines are self-locking and fixed to support the B-type cabin;

[0045] S6.6: Install longitudinal laminated wood, transverse laminated wood, and pour epoxy resin;

[0046] According to the above-mentioned method for installing and positioning the ship-borne B-type cabin using a three-dimensional adjustment machine, the installation requirements of the gap L are: L = the width ZK of the longitudinal laminated wood + the thickness HY of the epoxy resin, and the tolerance of the thickness HY of the epoxy resin is ±10mm;

[0047] The installation requirement of gap B is: B = width HK of horizontal laminated wood + thickness HY of epoxy resin, and the tolerance of thickness HY of epoxy resin is ±10mm.

[0048] According to the above-mentioned method for installing and positioning a ship-borne B-type cabin using a three-dimensional adjustment machine, in step S7: after the installation of the B-type cabin is completed, the three-dimensional adjustment machine is moved to the top open-air cabin, and then transferred out of the hull by a lifting device.

[0049] The beneficial effects of the present invention are as follows:

[0050] 1. The present invention extends the main vertical plate and the middle area of ​​the panel of the original B-type cabin vertical saddle, and sets a plurality of reinforcing brackets between the newly extended main vertical plate and the panel; the main vertical plate, the panel, and the reinforcing bracket are combined to form a support point for the three-dimensional adjustment machine to work; at the same time, the structure of the hull at the arrangement position of the three-dimensional adjustment machine is strengthened, and reinforcing ribs are set between the inner bottom longitudinal girder and the T-shaped steel, and reinforcing flat irons are set between the angle steels, which meets the requirement that the structure of the hull at the arrangement position can withstand the pressure of the three-dimensional adjustment machine in the working state, and improves the installation and positioning accuracy of the B-type cabin.

[0051] 2. The present invention arranges the three-dimensional adjustment machines on both sides of the vertical saddle of the B-type cabin at the four corners of the bottom of the B-type cabin and the middle positions on the left and right sides. Two three-dimensional adjustment machines are arranged near each vertical saddle of the B-type cabin. The three-dimensional adjustment machines are connected to the central control console at the rear side of the B-type cabin along the outer edge of the B-type cabin using a communication bus; the open area in the middle position of the bottom of the B-type cabin is used as a personnel and material passage; the arrangement position and number of the three-dimensional adjustment machines are more reasonable, and the structural interference problem when installing the ship-borne B-type cabin is solved, and personnel and material passages are set. After the installation of the B-type cabin is completed, the three-dimensional adjustment machine can be transferred out of the hull. The three-dimensional adjustment machine is reasonably arranged and easy to move, which improves the accuracy of installation and positioning of the B-type cabin and reduces the production cost.

[0052] 3. The present invention arranges height-adjustable universal wheels on both sides of the three-dimensional adjustment machine body. When the three-dimensional adjustment machine is moved, the universal wheels are extended and the base leaves the ground; when the three-dimensional adjustment machine is working, the universal wheels are retracted and the base contacts the ground. The positioning of the three-dimensional adjustment machine body is stable, which further improves the accuracy and efficiency of the three-dimensional adjustment machine for installation and positioning of the ship-borne type B cabin.

[0053] 4. The present invention adjusts the transverse and longitudinal positions of the B-type cabin by the first hoisting hovering, so that each saddle of the B-type cabin is aligned with each saddle of the hull; the second hoisting hovering makes the longitudinal saddle of the B-type cabin enter between the longitudinal saddles of the hull, and the transverse saddle of the B-type cabin enters between the transverse saddles of the hull; the gap L, gap B and gap H of the ship-borne B-type cabin are adjusted by the three-dimensional adjustment machine; the accuracy of the installation and positioning of the ship-borne B-type cabin by the three-dimensional adjustment machine is ensured.

[0054] 5. The present invention has high precision in installation and positioning of ship-borne type B cabins, so there is no need to cut or replace longitudinal laminated wood and transverse laminated wood to cooperate with the installation of type B cabins; the epoxy resin for bonding laminated wood can also be filled according to design requirements; it solves the problem that laminated wood is usually not available in stock and needs to be customized, and is expensive and has a long production cycle, and the problem that the epoxy resin for bonding laminated wood cannot meet the design requirements. Therefore, this method will greatly shorten the construction period and reduce production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0095] like Figure 15-17As shown: in the step S1: the three-dimensional adjustment machine 15 includes a body, a vertical cylinder 19, a longitudinal cylinder 20, and a transverse cylinder 21 arranged on the side wall of the body; a displacement and pressure sensor 25 is arranged inside the body; a base 22 is arranged at the lower part of the vertical cylinder 19; a hydraulic pump station 24 is arranged at the bottom of the three-dimensional adjustment machine 15 body; height-adjustable universal wheels 23 are arranged on both sides of the three-dimensional adjustment machine 15 body, when the three-dimensional adjustment machine 15 is moved, the universal wheels 23 are extended, and the base 22 leaves the ground; when the three-dimensional adjustment machine 15 is working, the universal wheels 23 are retracted, and the base 22 contacts the ground.

[0096] like Figure 9-11 As shown: in the step S1: the B-type cabin 1 is provided with a B-type cabin vertical saddle 3, and the B-type cabin vertical saddle 3 is provided with a main vertical plate 4 and a panel 5; the main vertical plate 4 is extended to form a new main vertical plate 401, and the middle area of ​​the panel 5 is extended to form a new panel 501; a plurality of reinforcing brackets 6 are provided between the new main vertical plate 401 and the new panel 501; the new main vertical plate 401, the new panel 501, and the reinforcing bracket 6 are combined to form a support point 9 for the three-dimensional adjustment machine 15 to work;

[0097] like Figure 12-13 As shown: the structure of the hull 2 ​​at the arrangement position of the three-dimensional adjustment machine 15 is strengthened, a reinforcing rib 12 is arranged between the inner bottom longitudinal girder 10 and the T-shaped steel 11 at the lower part of the B-type tank vertical saddle 3, and a reinforcing flat iron 13 is arranged between the angle steels 14, so that the structure of the hull 2 ​​at the arrangement position can withstand the pressure of the three-dimensional adjustment machine 15 in the working state;

[0098] The open area in the middle of the bottom of the B-type cabin 1 is used as a passage 18 for personnel and materials.

[0099] Before the B-type cabin 1 is installed, the vertical laminated wood 8 is installed on the vertical saddle 3 of the B-type cabin, and the longitudinal laminated wood 28 and the transverse laminated wood 29 are not installed.

[0100] The load-bearing capacity of the vertical cylinder 19 of the three-dimensional adjustment machine is 1.5 times the weight of the area of ​​the B-type cabin 1 it bears;

[0101] The horizontal pushing capacity of the longitudinal cylinder 20 and the transverse cylinder 21 is:

[0102] [weight of B-type cabin 1 / number of three-dimensional adjustment machines 15]×friction coefficient×1.5;

[0103] At the same time: [the height of the three-dimensional adjustment machine 15 + the height of the joist 26] < the distance from the support point 9 to the inner bottom plane 27;

[0104] [height of the three-dimensional adjustment machine 15 + height of the support beam 26 + stroke of the vertical cylinder 19]> distance from the support point 9 to the inner bottom plane 27;

[0105] The strokes of the longitudinal cylinder 20 and the transverse cylinder 21 are greater than the positioning accuracy range of the B-type cabin 1 hoisting equipment.

[0106] like Figure 14-19 As shown: in the step S1: the three-dimensional adjustment machine 15 is arranged at the four corners of the bottom of the B-type cabin 1 and on both sides of the B-type cabin vertical saddle 3 in the middle of the left and right sides, two three-dimensional adjustment machines 15 are arranged near each B-type cabin vertical saddle 3, and the three-dimensional adjustment machine 15 is connected to the central control console 17 at the rear side of the B-type cabin 1 along the outer edge of the B-type cabin 1 using the communication bus 16;

[0107] The steps of positioning the three-dimensional adjustment machine are as follows:

[0108] S1.1: The base 22 is pressed on the reinforcing rib 12 of the hull 2;

[0109] S1.2: A support beam 26 is erected above the vertical cylinders 19 of the two three-dimensional adjustment machines 15;

[0110] S1.3: The upper part of the middle position of the joist 26 corresponds to the support point 9 on the vertical saddle 3 of the B-type cabin.

[0111] After the three-dimensional adjustment machine 15 is arranged, wired and debugged, the B-type cabin 1 is hoisted into the hull 2 ​​using hoisting equipment.

[0112] like Figure 20-23 As shown: in the step S3: when the distance from the lower surface of the vertical laminated wood 8 of the B-type cabin 1 to the upper surface of the vertical saddle 7 of the hull is C1, where: C1=1000mm, the B-type cabin 1 stops falling, and the lower surface of the vertical laminated wood 8 is higher than the upper surface of the support beam 26; during the first hovering of the lifting equipment, the lateral position and longitudinal position of the B-type cabin are adjusted to align the saddles of the B-type cabin 1 with the saddles of the hull 2.

[0113] like Figure 24-27 As shown: In the step S5: the lifting equipment is made to drop the B-type cabin 1, and the distance from the lower surface of the vertical laminated wood 8 to the upper surface of the vertical saddle 7 of the hull is C2: wherein: when C2=100mm, the B-type cabin 1 stops falling again, and the lifting equipment hovers for the second time. At this time, the longitudinal saddle 30 of the B-type cabin enters between the longitudinal saddles 31 of the hull, and the transverse saddle 32 of the B-type cabin enters between the transverse saddles 33 of the hull.

[0114] In step S6, the steps of installing the B-type cabin 1 by operating the three-dimensional adjustment machine 15 include:

[0115] S6.1: Control the three-dimensional adjustment machine 15 through the central control console 17 to lift the vertical cylinder 19 and push it to the support point 9 through the support beam 26;

[0116] S6.2: The hoisting equipment gradually drops the weight of the B-type cabin 1 onto the three-dimensional adjustment machine 15 in multiple times.
