Description

Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to a column installation auxiliary tool and a column installation method. Background Art

[0002] There are over 300 decks on a RoRo ship, including both fixed and movable decks. To ensure deck height and facilitate installation, numerous columns are installed between adjacent decks. The verticality of the columns is crucial, and guide slots are provided on the sides of the columns. During installation, the decks enter through these slots and slide down to their installation positions. Due to the large size of the decks, and the fact that each deck is equipped with at least four columns for simultaneous guidance, any deviation from the verticality of the columns can prevent the decks from being lowered. Therefore, to ensure verticality, the cranes used for hoisting the columns have poor operating precision, resulting in extremely long hoisting times. This extends the platform assembly and docking period, impacting the normal operation of the RoRo ship. Furthermore, because the columns are shipped in batches, diagonal braces are often welded onboard to store the columns before installation due to a lack of suitable storage space. After the columns are installed, the diagonal braces are removed, leaving numerous weld marks on the hull, commonly known as "stubs," which require subsequent polishing, adding unnecessary processing steps.

[0003] Therefore, it is urgent to design a column installation auxiliary tooling and a column installation method to solve the above problems. Summary of the Invention

A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0044] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0045] This embodiment provides a column installation auxiliary tool, which can quickly position and install the column 200 to a vertical state, and can be used to install columns 200 at multiple column installation positions on the same layer, eliminating the need for diagonal bracing and shortening the installation time of the entire dock. Figure 1 and Figure 2As shown, the column installation auxiliary tooling includes a base 10, a U-shaped frame 20 and a U-shaped operating platform 30. The base 10 includes a U-shaped mounting part 11, a universal wheel 12 and a switch magnet 13. The four corners of the U-shaped mounting part 11 are equipped with universal wheels 12. The relative position of the universal wheel 12 and the U-shaped mounting part 11 in the vertical direction is adjustable. The four corners of the U-shaped mounting part 11 are equipped with switch magnets 13; the U-shaped frame 20 is installed on the upper side of the U-shaped mounting part 11 in the vertical direction; the U-shaped operating platform 30 is installed on the upper end of the U-shaped frame 20.

[0046] The column installation auxiliary tooling is implemented by installing a universal wheel 12 and a switch magnet 13 on a U-shaped mounting part 11. After the column installation auxiliary tooling is moved to the position to be installed by moving the universal wheel 12, the universal wheel 12 is adjusted to rise so that the switch magnet 13 is adsorbed onto the deck (the bottom deck is the inner bottom plate. As the decks are installed layer by layer, the bottom of the column 200 of the lower deck needs to be installed on the installed deck of the lower layer. The deck is a metal part). The column 200 enters from the opening of the column installation auxiliary tooling for rough positioning. After the bottom of the column 200 is positioned, the U-shaped operating platform 30 facilitates the vertical adjustment of the top of the column 200, quickly positioning and installing the column 200 to be vertical, and can be used to install the column 200 at multiple column installation positions on the same layer, eliminating the need for the setting of diagonal braces and shortening the installation time of the entire dock.

[0047] Alternatively, as Figure 2 As shown, the U-shaped mounting member 11 includes a main body 111 and a protrusion 112. The main body 111 is U-shaped, and the protrusions 112 are arranged along the four corners of the main body 111. The switch magnet 13 is mounted on the main body 111, and the universal wheel 12 is connected to the protrusion 112. This arrangement rationally arranges the positions of the universal wheel 12 and the switch magnet 13, providing a larger mounting surface. In other embodiments, the positions of the universal wheel 12 and the switch magnet 13 can be interchanged, which is not limited here.

[0048] Optionally, the universal wheel 12 is connected to the U-shaped mounting member 11 via a stud 15 , and the position of the universal wheel 12 relative to the U-shaped mounting member 11 in the vertical direction can be adjusted by screwing the stud 15 .

[0049] Preferably, if Figure 1 and Figure 2 As shown, the base 10 also includes reinforcement plates 14, mounted at each of the four corners of the U-shaped frame 20. One end of the reinforcement plate 14 is attached to the U-shaped mounting member 11, and the other end is connected to the corner of the U-shaped frame 20. This arrangement improves the mounting strength of the U-shaped frame 20. Specifically, the reinforcement plates 14 are mounted on the protrusions 112, spaced apart from the bolts. Optionally, the U-shaped frame 20 and the base 10 are connected by welding.

[0050] During the actual installation process of the columns 200, the height of the column installation auxiliary tooling will be made lower than the height of the columns 200 on that layer to ensure that the top of the column 200 is higher than the U-shaped operating platform 30 to play a limiting role. However, if the column 200 is too high, the height of the column installation auxiliary tooling needs to be changed to ensure that most of the columns 200 are roughly positioned to ensure stability. The height of each layer of columns 200 is different, and the height of the column installation auxiliary tooling used on different layers will also be different. In this embodiment, there are three heights of the column installation auxiliary tooling, and three U-shaped frames 20 with different heights need to be designed, which is more complicated to manufacture.

[0051] In order to solve the above problems, Figure 4 As shown, in this embodiment, the U-shaped frame 20 is divided into a first frame 21 with a height of H1, a second frame 22 with a height of H2, and a third frame 23 with a height of H3. The first frame 21 and the second frame 22 are stacked to form the third frame 23, where H3 = H1 + H2. The column installation auxiliary tooling can be assembled using any of the first frame 21, the second frame 22, and the third frame 23. With this arrangement, when manufacturing the U-shaped frame 20, only the first frame 21 and the second frame 22 need to be manufactured. The third frame 23 is connected by welding, eliminating the need to produce a separate frame. Optionally, the first frame 21 and the second frame 22 are both welded together using connecting rods.

[0052] Preferably, the U-shaped operating platform 30 includes a horizontal plate 31 and a reinforcing vertical plate 32. The reinforcing vertical plate 32 is installed on the lower side of the horizontal plate 31. The U-shaped frame 20 is connected to the horizontal plate 31. Through the above arrangement, the strength of the U-shaped operating platform 30 can be improved.

[0053] Preferably, the opening edges of the horizontal plate 31 are all provided with reinforcing vertical plates 32 , so that the area of ​​the column 200 abutting against the side wall of the column 200 after entering the horizontal plate 31 is increased, thereby improving the stability of rough positioning.

[0054] Preferably, the column installation auxiliary tooling further includes a railing 40 and a ladder 50. The railing 40 is U-shaped and installed on the outer periphery of the U-shaped operating platform 30, and the ladder 50 can lead to the U-shaped operating platform 30. Through the above arrangement, it is convenient for operators to enter the U-shaped operating platform 30, and the railing 40 ensures the safety of the operators.

[0055] This embodiment also provides a column installation method. By using the above-mentioned column installation auxiliary tooling, the column 200 can be quickly positioned and installed vertically, and the column 200 can be installed at multiple column installation positions on the same layer, eliminating the need for the setting of diagonal braces and shortening the installation time of the entire dock.

[0056] The column installation method includes:

[0057] S1: Push the column installation auxiliary tooling to the preset position, adjust the universal wheel 12 upward relative to the U-shaped mounting member 11 to separate from the deck, and turn on the switch magnet 13 so that the switch magnet 13 is attracted to the deck. This step ensures that the entire column installation auxiliary tooling is firmly positioned.

[0058] S2: Hoist the column 200 so that the column 200 enters through the opening of the column installation auxiliary tooling;

[0059] S3: The bottom of the column 200 is aligned and positioned. Two support assemblies 210 are welded to the bottom positioning plate. The two adjacent sides of the bottom of the column 200 are respectively abutted against the two support assemblies 210. Two more support assemblies 210 are welded to the bottom positioning plate so that the support assemblies 210 respectively abut the remaining two sides of the bottom of the column 200. The bottom positioning plate is the part of the inner bottom plate or deck used to install the column 200. Its strength is higher than other parts of the inner bottom plate or deck. First, two support assemblies 210 are welded so that the two connected sides of the bottom of the column 200 are abutted in place. Then, two more support assemblies 210 are welded to limit the four sides of the bottom of the column 200. At this time, the four sides of the bottom of the column 200 are in abutment with the corresponding support assemblies 210 rather than in a connected state. Due to the high height of the column 200, when the verticality of the column 200 is subsequently adjusted at the top, the amount of fine-tuning can be guaranteed without damaging the support assemblies 210.

[0060] S4: Measure the verticality of the column 200 on the U-shaped operating platform 30 and adjust the upper end position of the column 200 to adjust the column 200 to a vertical position. In this embodiment, the verticality accuracy of the four sides of the column 200 is sufficient when it leaves the factory, so the verticality of only three sides needs to be measured.

[0061] S5: Weld a backing plate onto the U-shaped operating platform 30 to hold the upper end of the column 200 in place. The four sides of the bottom of the column 200 are tack welded to the corresponding backing assembly 210. This step is to secure the vertically adjusted column 200 in place and prevent it from shaking. The backing plate can be welded to a suitable location on the horizontal plate 31 or the reinforcing plate 32.

[0062] S6: Recheck the verticality of column 200. If it meets the accuracy standard, remove the support plate on U-shaped operating platform 30. Simply smash the support plate when removing it. If there are any holes on U-shaped operating platform 30, no action is required (just ensure there are no holes on column 200 or the deck).

[0063] S7: Turn off the switch magnet 13, adjust the universal wheel 12 downward, so that the universal wheel 12 contacts the deck, and the switch magnet 13 is lifted off. The column installation auxiliary tool is pushed on the deck to the installation position of the next column 200. This step realizes the sequential installation of columns 200 at different positions on the same floor.

[0064] The column 200 installation method adopts the above-mentioned column installation auxiliary tooling. After the universal wheel 12 drives the column installation auxiliary tooling to the preset position, the universal wheel 12 is adjusted upward so that the switch magnet 13 is adsorbed on the deck, which can not only stably install at the preset position but also realize switching of multiple installation positions; after the column 200 is hoisted and enters from the opening of the column installation auxiliary tooling, the bottom falls to the positioning position, and after the side of the column 200 abuts the backrest assembly 210, the overall verticality of the column 200 is measured on the U-shaped operating platform 30. The operating platform is convenient for adjusting the top on the premise that the bottom of the column 200 is positioned to ensure that the overall verticality of the column 200 is qualified, and then the bottom is welded to the backrest assembly 210 and the top is welded to the back plate. After stabilization, the verticality is measured again, the back plate is removed, and the installation auxiliary tooling is moved to the next positioning position. During the entire process, the column installation auxiliary tooling first gives the column 200 a rough positioning, and the U-shaped operating platform 30 provides a base point for the vertical adjustment, reducing the dependence on the crane during vertical adjustment, avoiding the situation where the crane adjustment accuracy is poor and needs repeated adjustment, and improving the speed of adjusting the verticality of the column 200. It can also be used to install the column 200 at multiple column installation positions, eliminating the need for the setting of diagonal braces and shortening the installation time of the entire dock.

[0065] Preferably, between S2 and S3, there is a step S21: installing a stopper at the opening of the U-shaped operating platform 30 to close the opening; and between S6 and S7, there is a step S61: removing the stopper. The above arrangement prevents the upright column 200 from tipping over toward the opening when inside the U-shaped operating platform 30, thereby improving safety.

[0066] Optionally, in S4, a plumb bob is used to measure the verticality of column 200. A jack or basket is secured to the side of the U-shaped operating platform 30 so that the free end of the jack or basket abuts the side of column 200 to adjust the verticality of column 200. A plumb bob is a common device for measuring verticality, and its use is not described here. The jack and basket allow for convenient adjustment of the top position of column 200. Optionally, the jack or basket is secured to the U-shaped operating platform 30 by welding.

[0067] like Figure 5As shown, in order to improve the stable connection between the backrest assembly 210 and the bottom of the column 200, the thickness of the backrest 211 in the backrest assembly 210 will be more than 15 mm. Ordinary welding cannot weld to the inside of the backrest assembly 210. After long-term use, if corrosion occurs, it will lead to a loose connection. In order to solve the above problem, in S5, the backrest 211 is provided with a bevel 2111 at one end facing the side of the column 200, and the side of the column 200 is fixed to the bevel 2111 by full penetration welding. The setting of the bevel 2111 can provide sufficient welding space for welding, ensuring that the two are fully welded at the welding section after welding, thereby improving the reliability of the connection between the two.

[0068] Preferably, if Figure 5 As shown, the backrest assembly 210 may include at least two backrests 211 to ensure the balance of the corresponding side connections of the column 200.

[0069] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
