Description

Technical Field

[0001] This invention relates to the field of auxiliary tools for hull measurement, and in particular, auxiliary tools for hull measurement. Background Technology

[0002] Ships are a general term for all kinds of vessels. They are means of transportation that can navigate or anchor in waterways for transport or operations, and vary in technical performance, equipment, and structural type according to different usage requirements.

[0003] A ship is a man-made means of transportation that primarily operates in water. Civilian vessels are generally called ships, military vessels are called warships, and small boats are called boats or dinghies; collectively, they are referred to as ships or naval vessels. Internally, they mainly include interior space, supporting structures, and drainage structures, and possess a propulsion system that utilizes external or internal energy sources. Their external shape is generally a streamlined envelope that helps overcome fluid resistance. Materials are constantly updated with technological advancements; early materials included natural materials such as wood, bamboo, and hemp, while modern materials primarily include steel, aluminum, fiberglass, acrylic, and various composite materials.

[0004] Currently, total stations are widely used in shipbuilding. However, in the measurement of hull sections and overall sections, due to the complexity of the working conditions, it is often necessary to carry various auxiliary measuring tools during the measurement process. These auxiliary measuring tools include: measuring tape, steel ruler, right-angle ruler, and reflective sheets for measuring points. Different auxiliary measuring tools need to be used according to different working conditions on site, and a variety of auxiliary measuring tools need to be carried to meet the measurement accuracy requirements.

[0005] During ship surveying, there are numerous structural points to be measured, and these points vary in form. Frequent changes to auxiliary measuring tools can lead to low measurement efficiency. Furthermore, the large number and small size of the auxiliary measuring tools carried increase the risk of loss. Summary of the Invention

[0006] The purpose of this invention is to provide a hull measurement auxiliary tool that integrates multiple tools to reduce the inefficiency caused by frequent replacement of auxiliary measuring tools.

[0007] The technical solution to achieve the above objective is: a ship hull measurement auxiliary tool, including a main scale, one end of which is connected to a secondary scale, the secondary scale and the main scale being vertically distributed, reflective sheets being provided at both ends of the connection between the main scale and the secondary scale, a first sliding groove being provided at the upper end of the main scale, a sliding component being provided on the main scale, an adjustment component being provided on the sliding component, and a limit component being installed on the adjustment component.

[0008] Preferably, the sliding assembly includes a slider, a screw hole, a screw, a slide plate, a through hole, a first fixing plate, and a guide rod. The slider is slidably connected to the side wall of the first slide groove, and the top of the slider is provided with a screw hole. The outer wall of the main scale is connected to the first fixing plate, the side wall of the first fixing plate is connected to the guide rod, the outer wall of the guide rod is slidably connected to the slide plate, the top of the slide plate is provided with a through hole, and the side wall of the screw hole is threaded with a screw.

[0009] Preferably, the through hole and the screw hole are aligned, the screw passes through the through hole, and the top diameter of the through hole is larger than the bottom diameter of the through hole.

[0010] Preferably, the adjustment assembly includes a second fixed plate, a circular hole, a first limiting hole, an insertion hole, an insertion rod, a circular rod, a connecting block, and a second limiting hole. The second fixed plate is connected to the side wall of the main scale. The second fixed plate and the first fixed plate are located on the same side wall of the main scale. A circular hole is opened on the outer wall of the second fixed plate. An insertion hole is opened at the end of the guide rod away from the first fixed plate. An insertion rod is inserted and connected in the insertion hole. The distance between the insertion hole and the second fixed plate is greater than the width of the slide plate. A circular rod is connected to one end of the insertion rod. A connecting block is connected to the end of the circular rod away from the insertion rod. A second limiting hole is opened at the top of the connecting block.

[0011] Preferably, the limiting assembly includes a second sliding groove, a limiting plate, a limiting spring, a support block, a first limiting rod, a second limiting rod, and a limiting slot. The bottom end of the connecting block has a second sliding groove, the side wall of the second sliding groove is slidably connected to a limiting plate, the side wall of the limiting plate is connected to a limiting spring, one end of the limiting spring is connected to the connecting block, a first limiting rod is inserted into the first limiting hole, the top end of the first limiting rod is connected to a support block, the bottom end of the support block is connected to a second limiting rod, the outer wall of the second limiting rod is inserted into the second limiting hole, and a limiting slot is formed on the side wall of the second limiting rod.

[0012] Preferably, the first and second slides are both T-shaped, the limiting plate is L-shaped, and the second limiting hole penetrates the side wall of the connecting block.

[0013] Preferably, the side wall of the auxiliary ruler has a protractor hole.

[0014] Preferably, the slide plate is L-shaped, and a groove is formed on the side wall of the slide plate away from the through hole.

[0015] The beneficial effects of this invention are:

[0016] 1) Using the main ruler, draw auxiliary lines on the hull to locate the point to be measured. The main ruler and vernier ruler can be used as general rulers to measure straightness or allowance. They can also be used as extension rulers for obscured structural points. Use the protractor hole to measure the angle between lines. The sliding component can be used to easily draw quantitative line segments along the main ruler, thereby improving measurement efficiency. The adjustment component can be used to replace the slide plate. The slide plate wears out after long-term use, and it can be easily replaced to improve measurement accuracy.

[0017] 2) Open the adjustment assembly, insert the slide plate onto the guide rod, align the through hole with the screw hole, and screw the screw into the screw hole to fix the slide plate and the slider together. At this time, insert the marker into the groove. According to the required marking length and the scale on the main scale, press the main scale and push the marker. The marker will be stuck in the groove, allowing the marker to easily draw a line segment of the specified length. At the same time, the slide plate can be used as an extension section for easy comparison with the scale on the main scale.

[0018] 3) Insert the first limiting rod into the first limiting hole and the second limiting rod into the second limiting hole, thus initially fixing the connecting block and the second fixing plate together. At this time, the tops of the support block and the connecting block are in contact. At the same time, pull the limiting plate outward, and the limiting plate pulls the limiting spring. After the second limiting rod passes through the second limiting hole, release the limiting plate, so that the limiting spring pushes the limiting plate back and inserts it into the limiting slot, thus fixing the connecting block and the second fixing plate together. The reverse operation can be used to untie it, achieving the effect of fixing and stabilizing the adjustment component and making it easy to open, thus achieving the effect of conveniently replacing the slide plate.

The second fixing plate 601 is connected to the side wall of the main scale 1. The second fixing plate 601 and the first fixing plate 506 are located on the same side wall of the main scale 1. The outer wall of the second fixing plate 601 has a round hole 602. The end of the guide rod 507 away from the first fixing plate 506 has an insertion hole 604. The insertion rod 605 is inserted into the insertion hole 604. The distance between the insertion hole 604 and the second fixing plate 601 is greater than the width of the slide plate 504. One end of the insertion rod 605 is connected to the round rod 606. The end of the round rod 606 away from the insertion rod 605 is connected to the connecting block 607. The top of the connecting block 607 has a second limiting hole 608.

[0039] Pass the round rod 606 through the round hole 602, and insert the insertion rod 605 into the insertion hole 604 to complete the initial fixation, connecting the round rod 606 and the guide rod 507 into one piece, so that the connecting block 607 is in contact with the second fixing plate 601. The connecting block 607 cannot pass through the round hole 602. At this time, the limiting component 7 fixes the connecting block 607 and the second fixing plate 601 together, thereby fixing the round rod 606 and the guide rod 507 together. To open the connection between the round rod 606 and the guide rod 507, simply reverse the above operation.

[0040] Reference Appendix Figure 6-10 The limiting assembly 7 includes a second sliding groove 701, a limiting plate 702, a limiting spring 703, a support block 704, a first limiting rod 705, a second limiting rod 706, and a limiting slot 707.

[0041] After passing the round rod 606 through the round hole 602 and inserting the insertion rod 605 into the insertion hole 604, initial fixing is completed, connecting the round rod 606 and the guide rod 507 into one piece. After the connecting block 607 is in contact with the second fixing plate 601, the first limiting rod 705 is inserted into the first limiting hole 603, and the second limiting rod 706 is inserted into the second limiting hole 608. This initially fixes the connecting block 607 and the second fixing plate 601 together. At this time, the top ends of the support block 704 and the connecting block 607 are in contact. When the limiting plate 702 is pulled outward, the limiting plate 702 pulls the limiting spring 703. After the second limiting rod 706 passes through the second limiting hole 608, the limiting plate 702 is released, and the limiting spring 703 pushes the limiting plate 702 back and inserts it into the limiting slot 707, thereby fixing the connecting block 607 and the second fixing plate 601 together. The reverse operation can be used to disassemble it, which realizes the fixed and stable function of the adjusting component 6 and the effect of easy opening, and realizes the effect of easy replacement of the sliding plate 504.
