Description

Technical Field

[0001] The utility model relates to the technical field of reference wire frames, in particular to an adjustable reference wire frame for ships. Background Art

[0002] In shipbuilding, the centerline of the foundation serves as the reference line for hull foundation installation and positioning. A laser theodolite is typically used to confirm the position, and then a sample punch mark or steel wire is placed at the corresponding location to serve as a marker. Channel steel or angle steel is welded to the deck surface, and the wire is tightened using a hanging weight. Welding angles are generated after the channel steel or angle steel is removed.

[0003] For example, the Chinese utility model patent with authorization announcement number CN214870528U and authorization announcement date 2021.11.26 discloses a wire pulling tool for installing a deck pipe system bracket, which specifically includes two parallel wire racks and a wire drum for retracting and releasing the reference line. The wire rack includes a magnetic base, a vertical rod fixed to the top of the magnetic base, a slideway provided on the vertical rod, a slider provided on the slideway, a latch provided on the slider, an adjustment hole for matching the latch provided on the bottom of the slideway, and a wire clamping device provided on the slider. Place two wire racks at the confirmed position, adjust the sliders on both sides to the appropriate height and fix them, pull the reference line out of the wire drum, straighten it, and fix it with the wire clamping devices on both sides, and install the deck pipeline bracket on the deck along the reference line according to the spacing required by the design.

[0004] The existing wire-pulling tooling used for installing deck piping brackets consists of two wire racks, a wire reel, a magnetic base, and a wire clamp. The reference wire is pulled from the reel, straightened, and secured with clamps on either side. However, if the position of the wire rack on the deck deviates slightly, the magnetic base must be removed and repeatedly adjusted and installed, making it difficult to quickly and accurately complete the reference wire installation operation. Utility Model Content

[0005] The technical problem to be solved by the present invention is that if there is a slight deviation in the position of the wire rack placed on the deck, the magnetic base needs to be removed and repeatedly debugged and installed, making it difficult to quickly and accurately complete the operation of setting up the baseline.

[0006] In order to solve the above technical problems, the utility model provides a technical solution of an adjustable reference wire frame for ships:

[0007] The marine adjustable reference line frame includes a first bracket, a second bracket and a reference line. The lower parts of the first bracket and the second bracket are both provided with a magnetic seat, and the magnetic seat is used to detachably magnetically cooperate with the deck;

[0008] A first transverse screw and a first threaded sleeve are installed on the first bracket, the first transverse screw is fixedly arranged on the upper part of the first bracket, and the first threaded sleeve is threadedly engaged with the first transverse screw;

[0009] A second transverse screw and a second threaded sleeve are installed on the second bracket, the second transverse screw is fixedly arranged on the upper part of the second bracket, and the second threaded sleeve is threadedly engaged with the second transverse screw;

[0010] The first bracket is also equipped with a wire-receiving structure and a locking piece, and the locking piece is locked or unlocked with the wire-receiving structure; one end of the alignment line is connected to the second threaded sleeve, and the other end of the alignment line is connected to the wire-receiving structure, and the alignment line is overlapped with the outside of the first threaded sleeve.

[0011] Furthermore, a first limiting portion is provided on the outside of the first threaded sleeve, and a second limiting portion is provided on the outside of the second threaded sleeve. The first limiting portion and the second limiting portion cooperate with the alignment line in a transverse limiting manner.

[0012] Furthermore, the first limiting portion is a first card slot, which is opened in the middle of the outer wall of the first threaded sleeve, and the second limiting portion is a second card slot, which is opened in the middle of the outer wall of the second threaded sleeve.

[0013] Furthermore, the first bracket includes two first vertical rods that are spaced apart and parallel to each other, the first transverse screw is fixedly connected between the two first vertical rods, and the lower ends of the two first vertical rods are both equipped with the magnetic base.

[0014] Furthermore, the second bracket includes two second vertical rods that are parallel and spaced apart, the second transverse screw is fixedly connected between the two second vertical rods, and the lower ends of the two second vertical rods are both equipped with the magnetic base.

[0015] Furthermore, the wire-winding structure includes a rotating shaft and a wire-winding crank. The rotating shaft is installed between the two first vertical rods. The wire-winding crank is fixedly connected to one end of the rotating shaft. The rotating shaft is wound and connected to the outside of the rotating shaft.

[0016] Furthermore, a stopper is fixedly mounted on one end of the rotating shaft, and when locked, the stopper cooperates with a side transverse stopper of one of the first vertical rods.

[0017] Furthermore, the other end of the rotating shaft is also provided with an external thread section, which protrudes from the outside of the first vertical rod. The locking piece is a locking nut, which is threadedly engaged with the external thread section. When locked, the locking nut is pressed against the side of the other first vertical rod.

[0018] Furthermore, bearings are provided in the middle of the two first vertical rods, and the ends of the rotating shaft are assembled in the corresponding bearings.

[0019] Compared with the prior art, the utility model provides an adjustable marine reference line frame, which has the following beneficial effects: the adjustable marine reference line frame adopts a design form of a first bracket, a second bracket, a magnetic base and a reference line, wherein the lower parts of the first bracket and the second bracket are both provided with a magnetic base, which can be placed at the reference position of the deck through the magnetic base, and the magnetic base has an open magnetic attraction state and a closed magnetic attraction state. When open, the first bracket can be reliably fixed on the deck through the magnetic base, and when closed, the magnetic attraction force between the magnetic base and the deck disappears, and the first bracket and the second bracket can be disassembled and removed from the deck, thereby achieving the purpose of flexible disassembly and assembly for use without leaving welding angle codes on the deck.

[0020] The first bracket is mounted with a first transverse screw, a first threaded sleeve, a take-up mechanism, and a locking member. A second transverse screw and a second threaded sleeve are mounted on the second bracket. A reference line is connected between the second threaded sleeve, the first threaded sleeve, and the take-up mechanism. During operation, the take-up mechanism winds the reference line, straightening it between the first and second threaded sleeves to form a reference line. The locking member locks the take-up mechanism and maintains the straightened reference line. These reference lines are spaced apart on the upper portion of the deck, allowing for measurement of the lateral distance between the base and the reference line, thereby ensuring the accurate installation position of the base on the baseplate.

[0021] In addition, a first transverse screw is fixedly mounted on the upper portion of the first bracket, with a first threaded sleeve threadedly engaged with the first transverse screw. Correspondingly, a second transverse screw is fixedly mounted on the upper portion of the second bracket, with the second threaded sleeve threadedly engaged with the second transverse screw. Because the alignment line overlaps the exterior of the first threaded sleeve, the alignment line's transverse position on the first transverse screw is adjusted by rotating the first threaded sleeve, while the alignment line's transverse position on the second transverse screw is adjusted by rotating the second threaded sleeve. This eliminates minor positional deviations when the bracket is placed on the deck without having to remove the bracket, avoiding repeated adjustments and installation, and enabling quick and accurate completion of the baseline installation operation.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0030] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; they can refer to direct connection or indirect connection through an intermediate medium; they can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0031] like Figures 1 to 4As shown, an adjustable reference line frame for ships in an embodiment of the present invention includes a first bracket 1, a second bracket 2 and a reference line 4. The lower parts of the first bracket 1 and the second bracket 2 are provided with a magnetic seat 3, which is used for detachable magnetic engagement with the deck 6; a first transverse screw 10 and a first threaded sleeve 11 are installed on the first bracket 1, and the first transverse screw 10 is fixedly arranged on the upper part of the first bracket 1, and the first threaded sleeve 11 is threadedly engaged with the first transverse screw 10.

[0032] A second transverse screw 20 and a second threaded sleeve 21 are installed on the second bracket 2. The second transverse screw 20 is fixedly arranged on the upper part of the second bracket 2, and the second threaded sleeve 21 is threadedly engaged with the second transverse screw 20; a wire-taking structure 5 and a locking piece 50 are also installed on the first bracket 1, and the locking piece 50 is locked or unlocked with the wire-taking structure 5; one end of the alignment line 4 is connected to the second threaded sleeve 21, and the other end of the alignment line 4 is connected to the wire-taking structure 5, and the alignment line 4 is overlapped on the outside of the first threaded sleeve 11.

[0033] The marine adjustable reference line frame adopts a design form of a first bracket 1, a second bracket 2, a magnetic base 3 and a reference line 4, wherein the lower parts of the first bracket 1 and the second bracket 2 are both provided with a magnetic base 3, which can be placed in the reference position of the deck 6 through the magnetic base 3. The magnetic base 3 has an open magnetic state and a closed magnetic state. When open, the first bracket 1 can be reliably fixed on the deck 6 through the magnetic base 3. When closed, the magnetic force between the magnetic base 3 and the deck 6 disappears, and the first bracket 1 and the second bracket 2 can be disassembled and removed from the deck 6, so that they can be flexibly disassembled and used without leaving welding angle codes on the deck 6.

[0034] A first transverse screw 10, a first threaded sleeve 11, a take-up structure 5, and a locking member 50 are mounted on the first bracket 1. Furthermore, a second transverse screw 20 and a second threaded sleeve 21 are mounted on the second bracket 2. The alignment line 4 is connected between the second threaded sleeve 21, the first threaded sleeve 11, and the take-up structure 5. During use, the take-up structure 5 is operated to wind the alignment line 4, straightening the alignment line 4 between the first threaded sleeve 11 and the second threaded sleeve 21 to form a reference line. The locking member 50 then locks the take-up structure 5 and maintains the alignment line 4 in the straightened state. These reference lines are spaced apart on the upper portion of the deck 6 and can be used to measure the lateral distance between the base 7 and the alignment line 4, thereby ensuring the accuracy of the base 7's installation position on the baseplate 6.

[0035] In addition, a first transverse screw 10 is fixedly mounted on the upper portion of the first bracket 1, and a first threaded sleeve 11 is threadedly engaged with the first transverse screw 10. Correspondingly, a second transverse screw 20 is fixedly mounted on the upper portion of the second bracket 2, and a second threaded sleeve 21 is threadedly engaged with the second transverse screw 20. Because the reference line 4 overlaps the exterior of the first threaded sleeve 11, the transverse position of the reference line 4 on the first transverse screw 10 is adjusted by rotating the first threaded sleeve 11, and the transverse position of the reference line 4 on the second transverse screw 20 is adjusted by rotating the second threaded sleeve 21. This eliminates minor positional deviations of the bracket on the deck 6 without having to remove the bracket, avoiding repeated debugging and installation, and enabling the rapid and accurate completion of the reference line installation operation.

[0036] In this embodiment, a first limiting portion 110 is provided on the exterior of the first threaded sleeve 11, and a second limiting portion 210 is provided on the exterior of the second threaded sleeve 21. The first limiting portion 110 and the second limiting portion 210 cooperate with the alignment line 4 to provide lateral positional restraint. Specifically, the first limiting portion 110 is a first retaining groove located in the middle of the outer wall of the first threaded sleeve 11, and the second limiting portion 210 is a second retaining groove located in the middle of the outer wall of the second threaded sleeve 21. The first retaining groove of the first threaded sleeve 11 and the second retaining groove of the first threaded sleeve 11 serve as a retaining mechanism for the alignment line 4, ensuring that the alignment line 4 can be stably adjusted in lateral position when the threaded sleeve is rotated.

[0037] As a further preferred embodiment, the first bracket 1 includes two parallel, spaced-apart first vertical rods 12, a first transverse screw 10 fixedly connected between the two first vertical rods 12, and a magnetic base 3 mounted at the lower end of each of the two first vertical rods 12. The second bracket 2 includes two parallel, spaced-apart second vertical rods 22, a second transverse screw 20 fixedly connected between the two second vertical rods 22, and a magnetic base 3 mounted at the lower end of each of the two second vertical rods 22. In other words, the two first vertical rods 12 and the first transverse screw 10 form a first gantry structure, while the two second vertical rods 22 and the second transverse screw 20 form a first gantry structure, resulting in a simpler and more reliable gantry structure.

[0038] The wire take-up structure 5 includes a rotating shaft 51 and a wire take-up crank 52. The rotating shaft 51 is mounted between the two first vertical rods 12. The wire take-up crank 52 is fixedly connected to one end of the rotating shaft 51, and the rotating shaft 51 is wound around the outside of the rotating shaft 51. The wire take-up crank 52 drives the rotating shaft 51 to reel in or unreel the line 4, making the wire take-up and unreeling operations more convenient. Furthermore, bearings 55 are provided in the middle of each of the first vertical rods 12. The ends of the rotating shaft 51 are assembled in the corresponding bearings 55. The bearings 55 are designed between the first vertical rods 12 and the rotating shaft 51, improving the precision of the wire take-up rotation.

[0039] In addition, a stopper 53 is fixedly mounted on one end of the rotating shaft 51. When locked, the stopper 53 engages laterally against the side of one first vertical rod 12. The other end of the rotating shaft 51 is also provided with an externally threaded section 54, which protrudes from the outside of the first vertical rod 12. The locking member 50 is a locking nut that threadably engages with the externally threaded section 54. When locked, the locking nut presses against the side of the other first vertical rod 12. To secure the straightened alignment line 4, the locking nut is tightened against the side of the other first vertical rod 12. The locking nut and the stopper 53 jointly generate a transverse tightening force on the rotating shaft 51, thereby locking the line take-up structure 5 to keep the alignment line 4 straight.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
