Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding, in particular to a positioning tool for installing a ship T-profile and a ship T-profile installation method. Background Art

[0002] In the process of shipbuilding, the use of steel sections, especially T-sections, is quite common because they can provide excellent mechanical properties and structural stability. With its unique "T"-shaped cross-section design, T-sections are ideal for keels, ribs and other key structural parts. However, in actual operation, especially during placement, transportation, and installation, the positioning of T-sections has become a thorny issue. In particular, when the flange plate of the T-section is placed upward, it is easy to tip over due to the high center of gravity, which not only increases the difficulty of construction, but also poses a safety hazard.

[0003] In order to avoid the risk of tipping over during placement and transportation, the usual practice is to fix the T-profile on the base or bracket by welding or other fixing methods. However, although this method is effective, it greatly increases the overall workload. In addition, the welding process is time-consuming. If the overall workload is increased, it will lead to a longer overall time consumption, which is not conducive to improving production efficiency.

[0004] In order to improve efficiency, some specially designed tooling is usually used to assist in the installation of T-profiles. The purpose of designing these tooling is to simplify the installation process and reduce unnecessary fixing work while ensuring safety. However, most of the existing tooling designs have certain limitations. For example, they often directly connect the entire T row, which means that once the number of T profiles in the T row changes, new tooling needs to be replaced, resulting in poor adaptability of the tooling. In addition, some existing tooling structures are relatively complex, which brings inconvenience to production and handling. In view of this, there is an urgent need to develop a more flexible and simple-structured tooling to meet the installation needs of different numbers of T profiles. Summary of the invention

[0005] In view of the problems that the existing tooling has poor adaptability, complex structure, and is inconvenient to produce and carry, the present invention provides a tooling for installing ship T-profiles and a ship T-profile installation method. Two adjacent T-profiles are positioned by a tooling, and the tooling can effectively achieve equal spacing between two adjacent T-profiles and prevent the T-profiles from tipping over. As the number of T-profiles to be installed increases, only the corresponding number of tooling needs to be added. The tooling has strong applicability, simple structure, low production cost, easy use, and easy to carry.

[0006] The technical solution adopted by the present invention is:

[0007] A positioning tool for installing T-profiles on ships, comprising a support beam, a first "L"-shaped clamping portion, and a second "L"-shaped clamping portion. The two first "L"-shaped clamping portions are respectively fixedly connected to the two ends of the support beam, and the two second "L"-shaped clamping portions are respectively arranged opposite to the two first "L"-shaped clamping portions. The ends of the first "L"-shaped clamping portion and the second "L"-shaped clamping portion form a clamping accommodating cavity for clamping the T-profile.

[0008] Furthermore, it also includes an adjusting bolt and a threaded rod, wherein the second "L"-shaped clamping portion is slidably connected to the support beam; the threaded rod is formed by welding two bolts with external threads in opposite directions at the nut, and the two bolts are respectively threadedly connected to the two second "L"-shaped clamping portions;

[0009] The two adjusting bolts are respectively arranged at the ends of the two first “L”-shaped clamping parts.

[0010] Furthermore, the second "L"-shaped clamping portion is nested in the slide groove of the support beam through the slider at its upper end; the cross-sections of the slide groove and the slider are both "T"-shaped.

[0011] Furthermore, the second "L"-shaped clamping portion is sleeved on the support beam through a sleeve at its upper end.

[0012] Furthermore, the threaded rod is arranged opposite to the horizontal section of the second "L"-shaped clamping portion.

[0013] Furthermore, the lower end of the second "L"-shaped clamping portion extends d 1 Greater than the length of the T-section flange protruding from the T-section web d 2 .

[0014] Furthermore, the support beam, the first "L"-shaped clamping portion, and the second "L"-shaped clamping portion are all made of metal.

[0015] A method for installing a ship T-profile based on the positioning tool for installing a ship T-profile, comprising the following steps:

[0016] S1. Fix the first T-shaped profile at the installation position according to the installation requirements;

[0017] S2. Place the second T-profile in parallel with the first fixed T-profile at a set interval, use a positioning tool, and respectively cover the two clamping accommodating cavities at both ends of at least one positioning tool on the adjacent T-profiles to position the two adjacent T-profiles, and then place the next T-profile in turn and position it using the positioning tool; after positioning the T-profile using the positioning tool, perform the fixing operation.

[0018] Furthermore, in step S2, when the spacing distance between two adjacent T-profiles does not match the distance between the two clamping cavities of the positioning fixture, the positioning fixture is tilted and / or the adjusting bolts and threaded rods of the positioning fixture are adjusted to adapt to the spacing between the two T-profiles.

[0019] The beneficial effects of the present invention are:

[0020] When using the positioning fixture of the present invention, two adjacent T-profiles are positioned by one positioning fixture, and as the number of T-profiles to be installed increases, only the corresponding number of fixtures need to be added, without the need to replace new fixtures, and the applicability is strong. In addition, the fixture can effectively achieve equal center spacing positioning between two adjacent T-profiles, and can also prevent the T-profiles from tipping over.

[0021] In the invention, the adjusting bolt can be preliminarily adjusted in advance according to the spacing between the T-profiles, and the threaded rod can be further adjusted so that the two adjacent T-profiles are further clamped, the installation effect is good, and the T-profile is not easy to fall off. In addition, the adjusting bolt can also be further adjusted after installation, and the T-profile installation effect is good by adjusting the adjusting bolt and the threaded rod multiple times. Only one rotation of the threaded rod is required to clamp the two T-profiles at the same time, which is convenient to use.

[0022] The threaded rod is arranged opposite to the horizontal section of the second "L"-shaped clamping part, so that the threaded rod will not interfere with the clamping and installation of the T-profile; and the upper and lower ends of the accommodating cavity can limit the T-profile, increasing the stability of the installation. The sleeve is arranged outside the support beam. On the one hand, there is no need to process holes and grooves inside the support beam, reducing the difficulty of processing. On the other hand, the contact area between the sleeve and the support beam is larger, which is less likely to be damaged and less likely to get stuck. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention will be further described in detail below with reference to the specific implementation modes of the accompanying drawings, but the protection scope of the present invention is not limited thereto. Example

[0034] Figure 1-4 A structure of a positioning tool for installing T-profiles for ships as described in the present invention, the positioning tool includes a support beam 1, a first "L"-shaped clamping part 2, a second "L"-shaped clamping part 3, an adjusting bolt 4, and a threaded rod 5. The two first "L"-shaped clamping parts 2 are respectively fixedly connected to the two ends of the support beam 1, and the two second "L"-shaped clamping parts 3 are respectively arranged opposite to the two first "L"-shaped clamping parts 2. The ends of the first "L"-shaped clamping part 2 and the second "L"-shaped clamping part 3 form a clamping accommodating cavity 6 for clamping the T-profile 7.

[0035] The second "L"-shaped clamping portion 3 is slidably connected to the support beam 1. Specifically, in this embodiment, the sliding of the second "L"-shaped clamping portion 3 is achieved through a sliding groove structure. Figure 3-4 As shown, a slide groove 11 is arranged in the support beam 1, and a slider 31 cooperating with the slide groove 11 is arranged on the upper end of the second "L"-shaped clamping part 3. The slider 31 on the upper end of the second "L"-shaped clamping part 3 is nested in the slide groove 11 of the support beam 1, so that the second "L"-shaped clamping part 3 can slide relative to the support beam 1; the cross-sections of the slide groove 11 and the slider 31 are both "T"-shaped, which can prevent the slider 31 from falling off in the slide groove 11.

[0036] The support beam 1, the first "L"-shaped clamping portion 2, and the second "L"-shaped clamping portion 3 are all made of metal. The use of metal materials can ensure that the overall strength meets the use requirements.

[0037] Two adjusting bolts 4 are respectively arranged at the ends of the two first “L”-shaped clamping parts 2 , and the distance between the head of the adjusting bolt 4 and the second “L”-shaped clamping part 3 can be adjusted to adapt to the spacing between adjacent T-shaped bars 7 .

[0038] The threaded rod 5 is formed by welding two bolts with opposite rotation directions of external threads 51 at the nut, and the two bolts are respectively threadedly connected with the two second "L"-shaped clamping parts 3. When the threaded rod 5 is rotated, the threaded rod 5 drives the two second "L"-shaped clamping parts 3 to move left and right, and because the external threads 51 at both ends of the threaded rod 5 rotate in opposite directions, the two second "L"-shaped clamping parts 3 move in opposite directions, thereby adjusting the width of the accommodating chamber 6, so that only one rotation of the threaded rod 5 is required to clamp the two T-shaped profiles 7 at the same time, which is convenient to use. The threaded rod 5 is arranged opposite to the horizontal section of the second "L"-shaped clamping part 3. Specifically, an internal thread hole is arranged in the horizontal section of the second "L"-shaped clamping part 3. The external thread 51 on the threaded rod 5 is threadedly connected with the internal thread hole in the horizontal section of the second "L"-shaped clamping part 3, so that the threaded rod 5 will not interfere with the clamping and installation of the T-shaped profile 7, and the upper and lower ends of the accommodating chamber 6 can limit the T-shaped profile 7, thereby increasing the stability of the installation. In addition, there is also enough space when using a tool to twist the threaded rod 5, which is convenient for operation.

[0039] In the present invention, the adjusting bolt 4 can be preliminarily adjusted in advance according to the spacing between the T-profiles 7, and the threaded rod 5 can be further adjusted so that the two adjacent T-profiles 7 are further clamped. Of course, the adjusting bolt 4 can also be further adjusted after installation.

[0040] Combination Figure 5-7 The distance between the lower end of the threaded rod 5 and the upper end of the horizontal section of the second "L"-shaped clamping part 3 is greater than the thickness of the T-shaped flange plate 71, so that when the positioning tool installs the T-shaped bar 7, the T-shaped flange plate 71 can be located between the lower end of the threaded rod 5 and the upper end of the horizontal section of the second "L"-shaped clamping part 3. d 1 Greater than the length of the T-shaped flange plate 71 protruding from the T-shaped web plate 72 d 2 ,like Figure 7 As shown, when the first “L”-shaped clamping portion 2 and the second “L”-shaped clamping portion 3 clamp the T-shaped bar 7, the lower end of the second “L”-shaped clamping portion 3 abuts against the web 62 of the T-shaped bar, so that the T-shaped bar 7 is less likely to fall off. Example

[0041] Different from the first embodiment, the second "L"-shaped clamping portion 3 in the present embodiment is slidably connected to the support beam 1. Figure 8-9As shown. A sleeve 32 is fixed to the upper end of the second "L"-shaped clamping part 3, and the second "L"-shaped clamping part 3 and the sleeve 32 can be fixed by welding. The sleeve 32 at the upper end of the second "L"-shaped clamping part 3 is sleeved outside the support beam 1, so that the second "L"-shaped clamping part 3 can slide relative to the support beam 1. By sleeve 32 being sleeved outside the support beam 1, on the one hand, there is no need to process holes and grooves inside the support beam 1, reducing the difficulty of processing. On the other hand, the contact area between the sleeve 32 and the support beam 1 is larger, less prone to damage, and less prone to getting stuck.

[0042] A method for installing a ship T-profile based on the positioning tool for installing a ship T-profile, comprising the following steps:

[0043] S1. Fix the first T-shaped bar 7 at the installation position according to the installation requirements.

[0044] S2. Place the second T-profile 7 in parallel to one side of the first fixed T-profile 7 at a set interval, use a positioning fixture, and respectively cover the two clamping accommodating cavities at both ends of at least one of the positioning fixtures on the adjacent T-profiles 7, position the two adjacent T-profiles 7, and then place the next T-profile 7 in sequence and use the positioning fixture to position it; after positioning the T-profile 7 using the positioning fixture, perform the fixing operation. When the interval between the two adjacent T-profiles 7 does not match the distance between the two clamping accommodating cavities of the positioning fixture, tilt the positioning fixture and / or adjust the adjusting bolts 4 and threaded rods 5 of the positioning fixture to adapt to the interval between the two T-profiles 7.

[0045] When using the positioning fixture of the present invention, two adjacent T-profiles 7 are positioned by a positioning fixture. As the number of T-profiles 7 to be installed increases, only the corresponding number of fixtures need to be added without replacing new fixtures, and the applicability is strong. In addition, the fixture can effectively achieve the equal center spacing positioning between two adjacent T-profiles 7, and can also prevent the T-profiles 7 from tipping over. In the present invention, the adjusting bolt 4 can be preliminarily adjusted in advance according to the spacing between the T-profiles 7, and the threaded rod 5 can be further adjusted so that the two adjacent T-profiles 7 are further clamped, the installation effect is good, and the T-profiles 7 are not easy to fall off; only the threaded rod 5 needs to be rotated once to clamp the two T-profiles 7 at the same time, which is convenient to use. The positioning fixture of the present invention has a simple structure, low production cost, and is easy to use and carry.

[0046] The examples are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essential content of the present invention belong to the protection scope of the present invention.
