Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding, and in particular to a fast marking device and a marking method for a dock position. Background Art

[0002] Ship assembly and construction is generally divided into several major construction stages, including dock construction, wharf construction, mooring test, and navigation test. Among them, dock construction, as the first stage in the ship assembly and construction process, plays a very important role in the ship assembly and construction process.

[0003] When a ship is assembled and built in a dock, the first step is the layout of the dock piers. The on-site construction department of the shipyard usually arranges the dock piers according to the dock position and dock pier layout drawings of the design department. Before the dock piers are arranged, it is necessary to survey and mark the dock grid lines. The function of the dock grid lines is to serve as the reference lines for positioning the ship sections and the overall sections (including the center line, rib inspection line, break seam line, etc.).

[0004] After the baseline survey is completed, the dock pier layout begins. The conventional method for arranging the dock piers is to use a tape measure or a long tape measure to mark the dock pier position, and then use a forklift to arrange the cement. This method has a slow marking speed and requires a high level of technical skills from the marking personnel. The method of marking with a tape measure or a long tape measure is difficult to control the accuracy of verticality.

[0050] In order to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings.

[0051] The present invention provides a rapid marking device for a dock pier position, comprising a center positioning ruler 1 arranged on the center line of a dock bottom, a telescopic ruler 2 movably arranged on the center positioning ruler 1 and capable of sliding along the length direction of the center positioning ruler 1, and a marking frame 3 movably arranged on the telescopic ruler 2 and capable of sliding along the length direction of the telescopic ruler 2.

[0052] The center positioning ruler 1 is used as the reference for the position of the entire device. The center positioning ruler should be placed on the center line of the dock bottom, and its center line should coincide with the center line 4 of the dock bottom. The center line of the dock bottom is a reference line pre-marked on the bottom of the dock, and the center line of the dock bottom is perpendicular to the rib inspection line 5. A first scale line 1-1 is provided on the side of the center positioning ruler 1. When placing the device, the 0 scale line of the first scale line 1-1 should be aligned with the rib position 0 on the center line of the dock bottom.

[0053] The center positioning ruler 1 is provided with a first slide groove 1-12 along its length direction, the telescopic ruler 2 is perpendicular to the center positioning ruler 1, and a first connecting mechanism is provided at one end of the telescopic ruler, the upper end of the first connecting mechanism 7 is rotatably connected to the telescopic ruler, and the lower end is slidably arranged in the first slide groove 1-12 of the center positioning ruler 1 so that the telescopic ruler 2 can slide along the center positioning ruler 1.

[0054] The first slide groove 1-12 on the center positioning ruler 1 runs through the top of the center positioning ruler 1 to the bottom thereof, that is, the first slide groove 1-12 is a notch that runs through the center positioning ruler 1 in the vertical direction. A center position positioning piece 1-9 is provided at the center of the bottom of the first connecting mechanism 7. When the lower end of the first connecting mechanism 7 extends into the first slide groove 1-12 and a part of its structure is stuck in the slide groove of the first slide groove 1-12, the center position positioning piece 1-9 at the bottom of the first connecting mechanism 7 can be used as an indicating reference to indicate that the center line of the center positioning ruler 1 coincides with the center line of the dock bottom, so as to ensure the position accuracy of the device, and further ensure the marking accuracy of the dock pier. A telescopic ruler position positioning piece 1-3 is provided on the side of the first connecting mechanism to cooperate with the first scale line 1-1 on the center positioning ruler to position the telescopic ruler 2 in the Y direction. The telescopic ruler position positioning piece 1-3 is located on the center line of the telescopic ruler 2.

[0055] Specifically, the first connecting mechanism 7 includes a block 1-2, a block fixing member 1-4 arranged on the side of the block 1-2 to lock the position of the block 1-2, a telescopic ruler rotating bearing 1-5 arranged on the upper surface of the block 1-2, a connecting slide shaft 1-10 arranged at the center of the lower surface of the block 1-2, and a telescopic ruler moving roller 1-8 arranged on the connecting slide shaft 1-10 and movably clamped in the first slide groove 1-12. When the block 1-2 is clamped on the center positioning ruler 1 from above, the connecting slide shaft 1-10 at the bottom of the block 1-2 is engaged with the center positioning ruler 1. -10 The telescopic ruler moving roller 1-8 extending into the first slide groove 1-12 and fixed thereon is just stuck in the slideway of the first slide groove 1-12. When the clamping block 1-2 is made to slide along the first slide groove 1-12, the clamping block 1-2 can slide synchronously with the telescopic ruler 2, and the telescopic ruler 2 can slide synchronously with the marking frame 3, so as to adjust the position of the marking frame 3 in the Y direction. When the clamping block 1-2 is moved into place (that is, the position of the marking frame 3 in the Y direction is adjusted into place), the clamping block fixing member 1-4 is used to laterally press the clamping block 1-2 to lock it in the current position.

[0056] The telescopic ruler position positioning member 1-3 is arranged on the side of the card block 1-2 where the card block fixing member 1-4 is arranged. In this embodiment, a positioning groove 1-11 is arranged in the middle of the side of the card block 1-2 where the card block fixing member 1-4 is arranged, that is, the positioning groove 1-11 is arranged in the middle of the front and rear sides of the card block 1-2, and the telescopic ruler position positioning member 1-3 is arranged in the positioning groove 1-11. The telescopic ruler position positioning member 1-3 is a pointer, and its pointer needle point is vertically downward, and the needle point of the telescopic ruler position positioning member 1-3 points to the first scale line 1-1 on the side of the center positioning ruler 1 to judge whether the card block 1-2 is accurately moved into place.

[0057] In this embodiment, the block 1-2 can be set as a U-shaped block, and the block 1-2 is clamped on the center positioning ruler 1 from the top downward. The block fixing member 1-4 can be a screw or a bolt. When the block fixing member 1-4 is tightened, the head of the block fixing member 1-4 can press the block 1-2 from the side, thereby locking the block 1-2 in the current position.

[0058] The center position positioning member 1-9 is fixed on the connecting sliding shaft 1-10, and the center position positioning member 1-19 is vertically arranged. In this embodiment, the center position positioning member 1-9 is also a pointer, and its pointer needle point is vertically downward. The center position positioning member 1-9 can be used to determine whether the center line of the center positioning ruler 1 coincides with the center line 4 of the dock bottom.

[0059] In this embodiment, the telescopic ruler position positioning member 1-3 and the center position positioning member 1-9 are both located on the center line of the clamping block 1-2, and the connecting line of the telescopic ruler position positioning member 1-3 and the center position positioning member 1-9 is perpendicular to the center line of the dock bottom.

[0060] Since the telescopic ruler 2 is connected to the telescopic ruler rotating bearing 1-5 of the first connecting mechanism, it can realize horizontal rotation, and the position adjustment of the port side or starboard side of the marking frame 3 is indirectly realized by the rotation of the telescopic ruler 2, and the position of the marking frame 3 represents the position of the dock pier. Generally, there are two types of dock pier arrangements: 0° or 180°, that is, the dock pier can be located on the port side of the dock bottom centerline 4, or on the starboard side of the dock bottom centerline 4. By rotating the telescopic ruler, the marking frame 3 can be moved from a certain position on the port side of the dock bottom centerline 4 to a symmetrical position on the starboard side.

[0061] When the marking frame 3 is adjusted to the port side or the starboard side, in order to lock it to prevent the telescopic ruler 2 from rotating again under external force (such as accidental contact by a worker) and thus causing the position of the marking frame 3 to deviate, preferably, a telescopic ruler fixing block 1-6 can be added to the first connecting mechanism, and the telescopic ruler fixing blocks 1-6 are respectively vertically arranged on both sides of the clamping block 1-2, that is, Figure 2 As shown, the telescopic ruler fixing block 1-6 can be vertically fixed on the left and right sides of the clamping block 1-2.

[0062] The telescopic ruler fixing block 1-6 is provided with a third sliding groove 1-14, and the third sliding groove 1-14 is provided with a telescopic ruler fixing member 1-7 for locking the position of the telescopic ruler fixing block 1-6 so that the telescopic ruler fixing block 1-6 clamps the telescopic ruler 2 from both sides to prevent the telescopic ruler 2 from rotating. In this embodiment, the telescopic ruler fixing member 1-7 can be a bolt or a screw. When the marking frame 3 needs to be moved from a certain position on the port side of the dock bottom centerline 4 to a relatively symmetrical position on the starboard side, it is only necessary to loosen the telescopic ruler fixing member 1-7, so that the telescopic ruler fixing block 1-6 can be moved downward, thereby releasing the restriction of the telescopic ruler fixing block 1-6 on the left and right sides of the telescopic ruler 2, and the telescopic ruler 2 can rotate around the telescopic ruler rotating bearing 1-5; when the position of the marking frame 3 is rotated to the right position, the telescopic ruler fixing block 1-6 is moved upward, and the telescopic ruler 2 is restricted between the left and right telescopic ruler fixing blocks 1-6, and then the telescopic ruler fixing member 1-7 on the two telescopic ruler fixing blocks 1-6 is tightened, and the head of the telescopic ruler fixing member 1-7 presses the telescopic ruler fixing block 1-6, so that the left and right telescopic ruler fixing blocks 1-6 clamp the telescopic ruler 2, so that the telescopic ruler 2 can be prevented from rotating.

[0063] The telescopic ruler 2 is perpendicular to the center positioning ruler 1, and a second scale line 2-8 is provided on the side of the telescopic ruler 2, and the 0 scale line of the second scale line 2-8 is adjacent to the 0 scale line of the first scale line 1-1 on the center positioning ruler 1. A second sliding groove 1-13 with a downward opening is provided on the telescopic ruler 2 along its length direction, and the second sliding groove 1-13 is opened from the bottom of the telescopic ruler 2, but does not pass through the top of the telescopic ruler 2, that is, the second sliding groove 1-13 is a groove that does not pass through the telescopic ruler 2 in the vertical direction and the opening direction faces downward.

[0064] The other end of the telescopic ruler 2 is provided with a second connecting mechanism 8, the lower end of the second connecting mechanism 8 is rotatably connected to the marking frame 3, and the upper end is slidably arranged in the second slide groove 1-13 of the telescopic ruler 2 so that the marking frame 3 can slide along the telescopic ruler 2, and the side of the second connecting mechanism 8 is provided with a marking frame position positioning member 2-3 for cooperating with the second scale line on the telescopic ruler to position the marking frame 3 in the X direction.

[0065] Specifically, the second connecting mechanism 8 includes a connecting and fixing shaft 2-1 arranged at the center of the marking frame 3, a marking frame rotating bearing 2-5 arranged at the top of the connecting and fixing shaft 2-1, a marking frame connecting rod 2-4 arranged at the top of the marking frame rotating bearing 2-5, and a marking frame moving roller 2-6 arranged on the marking frame connecting rod 2-4 and movably clamped in the second sliding groove 1-13, and a marking frame fixing part 2-7 is vertically downwardly provided on the top of the telescopic ruler 2 to push down on the marking frame connecting rod 2-4 to lock the position of the marking frame 3 in the X direction.

[0066] The marking frame connecting rod 2-4 of the second connecting mechanism extends upward from the bottom of the telescopic ruler 2 into the second slide groove 1-13, and the marking frame moving roller 2-6 fixed thereon is just stuck in the slideway of the second slide groove 1-13. When the second connecting mechanism slides along the second slide groove 1-13, the second connecting mechanism can slide synchronously with the marking frame 3, so as to adjust the position of the marking frame 3 in the X direction. When the position of the marking frame 3 is moved into place, the marking frame fixing piece 2-7 is tightened downward so that the marking frame fixing piece 2-7 presses down on the marking frame connecting rod 2-4 to lock the marking frame 3 in the current position.

[0067] Since the connection fixing shaft 2-1 directly connected to the marking frame 3 is connected to the marking frame connecting rod 2-4 through the marking frame rotating bearing 2-5, the marking frame 3 can be directly rotated horizontally to adjust its length and width position.

[0068] The two sides of the connecting fixed shaft 2-1 are fixed with marking frame position positioning members 2-3 through transverse fixing members 2-2. The marking frame position positioning members 2-3 are used as an indicating reference for indicating the moving distance of the marking frame 3 to ensure the accuracy of the moving position of the marking frame 3, thereby ensuring the marking accuracy of the dock pier. The marking frame 3 cooperates with the second scale line on the side of the telescopic ruler 2 to locate the position of the marking frame 3 in the X direction, and judges whether the movement of the marking frame 3 is in place according to the corresponding scale on the telescopic ruler at its position.

[0069] In this embodiment, the marking frame position positioning member 2 - 3 is a pointer, and the tip of the pointer is vertically upward to indicate the second scale line 2 - 8 on the side of the telescopic ruler 2 .

[0070] In this embodiment, the inner frame size of the marking frame 3 is equal to the size of the dock pier. In actual use, the marking frame 3 of various specifications with corresponding sizes can be produced according to the size, model and type of the dock pier in the dock. When the sizes of the two dock piers to be marked are different, only the marking frame 3 needs to be replaced, and there is no need to replace the entire device, which greatly saves construction time. Since there is no need to replace the entire device, the time for subsequent device positioning is also reduced, further improving the marking efficiency of the dock pier in the dock.

[0071] The present invention also provides a method for marking a dock position using the above-mentioned dock position rapid marking device, which specifically includes the following steps:

[0072] S1, assembling the dock position rapid marking device and moving it to the position of the hull centerline pre-marked in the dock pier marking area.

[0073] S2, adjust the position of the dock pier position quick marking device so that its center position positioning member 1-9 is aligned with the center line of the dock bottom, so that the center line of the center positioning ruler 1 coincides with the center line of the dock bottom, and then align the 0 scale line on the center positioning ruler 1 with the No. 0 rib position on the center line of the dock bottom.

[0074] S3, according to the theoretical distance from the dock to be marked in the Y direction to the centerline 6 of the hull on the dock layout diagram (i.e., the theoretical distance from the dock to be marked in the Y direction to the rib position No. 0), adjust the telescopic ruler 2 to move along the length direction of the center positioning ruler 1 (the telescopic ruler 2 moves synchronously with the marking frame 3), until the scale value indicated by the telescopic ruler position positioning member 1-3 reaches the corresponding position, that is, the scale value indicated by the telescopic ruler position positioning member 1-3 should be equal to the theoretical distance from the dock to be marked in the Y direction to the centerline of the hull; then use the clamping block fixing member 1-4 to laterally press the clamping block 1-2 to lock the position of the telescopic ruler 2 in the Y direction.

[0075] S4, according to the side position of the dock to be marked (i.e., on the dock layout diagram, whether the dock to be marked is located on the port side or the starboard side of the dock bottom centerline), the telescopic ruler 2 is rotated, and the telescopic ruler 2 rotates with the marking frame 3 so that the marking frame 3 is located on the corresponding side.

[0076] S4, according to the theoretical distance from the dock to be marked in the X direction to the center line of the dock bottom on the dock layout diagram, adjust the marking frame 3 to move it along the length direction of the telescopic ruler 2 until the scale value indicated by the marking frame position positioning member 2-3 reaches the corresponding position (that is, the scale value indicated by the marking frame position positioning member 2-3 should be equal to the theoretical distance from the dock to be marked in the X direction to the center line of the dock bottom), and then use the marking frame fixing member 2-7 to press the marking frame connecting rod 2-4 downward to lock the marking frame 3 so that its position remains unchanged.

[0077] S5, draw lines at the four corners of the inner frame of the marking frame 3 to draw the dock pier position positioning line.

[0078] S6, connect the dock position positioning lines and draw the dock position.

[0079] According to the above method of the present invention, the positions of all dock piers in the dock can be marked in sequence. When the positions of the two dock piers marked with the front and rear lines are on different sides of the dock bottom centerline (for example, if the front dock pier with the positioning line marked is located on the port side of the dock bottom centerline, and the rear dock pier to be marked is located on the starboard side of the dock bottom centerline), it is only necessary to loosen the telescopic ruler fixing part 1-7 and rotate the telescopic ruler 180° to rotate the marking frame to a symmetrical opposite side position.

[0080] It should be clear that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
