Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a bracket tooling for shafting sample bars. Background Technology

[0002] In ship shafting systems, shafting templates are precision measuring tools used for inspecting and assembling shafting components. They serve as a quality control benchmark during production and are used to verify the positional accuracy of various shafting components. A single shafting system typically has a large number of templates, each exceeding 8 meters in length. Current technology uses a method of fixing shafting templates by welding angle irons to support the template. A T-shaped angle iron is then welded to each of the template's three or four equal divisions to support it, thus fixing the template. The template is then used as a reference for the installation and positioning of the shafting equipment. Fixing the template by welding angle irons requires at least 36 such T-shaped angle irons per ship, resulting in a large welding workload and involving personnel working across compartments, posing safety hazards. Furthermore, after the templates are used, a series of repair tasks are required, including cutting off the angle irons and grinding weld spatter. The entire construction process is cumbersome, involves numerous open flame operations, and carries low safety risks. Utility Model Content

[0021] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation.

[0022] Example 1

[0023] like Figures 1 to 3 As shown, this embodiment provides a bracket fixture for a shaft system sample bar, the bracket fixture comprising:

[0024] Main support 1 is a hollow cylindrical seamless steel pipe. U-shaped fixing frame 3 is welded to the bottom of main support 1. The U-shaped opening of fixing frame 3 is horizontal and faces the outside of main support 1. The combination of main support 1 and fixing frame 3 is L-shaped.

[0025] The fixing frame 3 includes two horizontally arranged clamping plates, at least one of which has bolt holes. The U-shaped opening of the fixing frame 3 is used to clamp the load-bearing components of the ship's shafting system. The fastening bolts 4 pass vertically through the bolt holes and abut against the surface of the load-bearing components to fix the main support. For example, the upper clamping plate has two bolt holes and is equipped with two fastening bolts 4 of the same specification. During installation, the main support 1 is installed on the load-bearing components by fastening the bolts 4, which can achieve the effect of supporting the shafting sample rod.

[0026] The bracket fixture also includes a rotating horizontal support 2 and a sleeve 5, both constructed from hollow cylindrical seamless steel pipes. The sleeve 5 is fitted onto the main support 1 and can move up and down along the main support 1. The rotating horizontal support 2 is horizontal and welded to the outer wall of the sleeve 5, specifically, it can be welded to the center of the sleeve 5. A bolt hole is also provided on the outer wall of the sleeve 5, along with a limiting member 6. The limiting member 6 passes through the bolt hole on the outer wall of the sleeve 5 and abuts against the outer wall of the main support 1, thus fixing the position of the sleeve 5. During installation and use, the sleeve 5 is fitted onto the main support 1, and the rotating horizontal support 2 can rotate 360° around the main support synchronously with the sleeve 5. Simultaneously, it can move up and down along the axial direction of the main support 1 to achieve the required installation position.

[0027] Multiple brackets are arranged along the ship's shafting direction, and multiple rotating cross supports 2 are used to support the shafting sample bars 10 arranged along the ship's shafting direction.

[0028] Furthermore, the load-bearing component includes an equipment base, which includes a T-shaped connected flat plate 21 and a longitudinal plate 22. The longitudinal plate divides the flat plate into two blocks along a direction parallel to the ship's shaft system, and the fixing frame is clamped at the edge of at least one block.

[0029] Furthermore, the edges of both blocks are clamped with the fixing frame 3 and the main support 1, and the two main supports 1 are respectively connected to the two ends of the same rotating cross support 2 through sleeves 5, thus forming a gate-shaped structure, thereby further improving stability and preventing positional displacement or swaying. Of course, in practice, for ease of height adjustment, in most cases only a single main support is used, which can also meet the support requirements.

[0030] Furthermore, when setting up two main supports, the two main supports do not need to be symmetrically arranged; that is, the connection between the two main supports does not necessarily have to be perpendicular to the direction of the ship's shafting. This is because, for a single load-bearing component, regardless of whether one or two main supports are set up, the rotating cross brace 2 can rotate, and therefore can be at any angle to the direction of the ship's shafting.

[0031] Furthermore, the surface of the rotating cross support 2 may be knurled to increase the contact friction with the shaft sample bar.

[0032] The steps for using the above-mentioned bracket tooling are as follows:

[0033] Using the load-bearing components inside the ship, the multiple sets of brackets in this application are fastened to the relevant load-bearing components by fastening bolts 4. The ship shafting sample bar is placed on the rotating cross support 2. The straightness of the ship shafting sample bar is ensured by adjusting the sleeve 5 up and down through the limiting component 6, so as to meet the construction requirements.

[0034] In summary, this utility model provides a bracket fixture for shafting sample bars. The bracket fixture includes a main support, with a fixing frame welded to the bottom end. The U-shaped opening of the fixing frame is used to clamp the load-bearing components of the ship's shafting system, thus fixing the main support. A sleeve is fitted onto the main support and can move up and down along it. A rotating cross support is horizontal and welded to the outer wall of the sleeve. Multiple main supports are arranged along the ship's shafting direction, and multiple rotating cross supports are used to support the shafting sample bars arranged along the ship's shafting direction, thus providing auxiliary fixation for the shafting sample bars. This bracket fixture is inexpensive and simple to manufacture. It allows for convenient and quick positioning and installation of ship shafting sample bars, improving both the installation quality and efficiency. It also enhances construction safety and shortens the construction cycle. Since there is no wear and tear during use, it can be reused, significantly saving costs and achieving energy conservation and emission reduction.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
