DETAILED DESCRIPTION

[0044] The technical solutions of the present application will be described clearly and completely below in combination with the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of the embodiments.

[0045] ​​​To solve the contradiction that the section cannot be directly hoisted into place, the workshop preliminary planning designs a tool to move the section from the side to the middle of the ship to move the section to the installation position. Considering that the heaviest section does not exceed 15 tons, the workshop planning and design rigid rail platform and shelf tool, through the laying of round steel on the track, using a hand hoist to move the section from the side to the middle of the ship and then lift it up to realize the installation of the section in place. The main operation is as follows:

[0046] Embodiment one of the shelf tool:

[0047] As shown in Figures 1-3 , it includes a sliding beam seat 3 and a profile support 4. The sliding beam seat 3 is a linear beam structure, as shown in Figure 2 , the material of the sliding beam seat 3 in this embodiment is processed and made of I-beam. Specifically, the cross section of the sliding beam seat 3 is in the shape of an "I", the upper end surface is a section fixing plate 11, the lower end surface is a rolling plate 12, and the beam seat vertical plate 13 is vertically arranged between the two. The upper side of the section fixing plate 11 is used to support and fix the ship section, and the rolling plate 12 is used to hoist the entire section to the rail platform 2 for sliding contact by the dock crane. The two sides of the beam seat vertical plate 13 are respectively provided with a plurality of reinforcing rib plates 14, as shown in Figure 1 , which effectively improve the lateral support force of the section fixing plate 11; one end of the beam seat vertical plate 13 is provided with a traction hole 15, and the two sides of the traction hole 15 are provided with reinforcing rings 16; when the section is hoisted into place, it is connected to the traction hole 15 by a hand hoist or other equipment, and the entire ship section is moved horizontally, so that the section is moved horizontally from the outside along the sliding rail 6 to the installation position of the original ship structure. The rolling plate 12 is fixedly provided with a reinforcing rib 17 at one end of the traction hole 15, and the bottom of the reinforcing rib 17 is flush with the lower end surface of the rolling plate 12. The width of the reinforcing rib 17 is equal to the width of the rolling plate 12. Since the rolling plate 12 contacts the round steel 8, and the end is first subjected to pressure from the round steel 8 during horizontal movement, in order to avoid end deformation, the reinforcing rib 17 is provided to improve the strength, and the bottom is flush with the rolling plate 12 to facilitate the rolling of the round steel 8 on the lower side of the rolling plate 12.

[0048] In this embodiment, as shown in Figure 1 , a pipe support 38 is vertically fixed on the section fixing surface, which supports the suspended position of the section above the sliding beam seat 3, thereby providing good support for the section. In actual use, the pipe support 38 is welded to the section, and the bottom of the curved section 7 in this embodiment is a flat surface, so that the bottom surface of the section is directly welded to the contact position of the sliding beam seat 3. The pipe support 38 extends upward to the outer surface of the curved section 7 to form a support therefor, and a triangular rib plate 18 can be provided between the side of the pipe support 38 and the section fixing plate 11, as shown in Figure 5 .

[0049] The upper end of the sliding beam seat 3 is provided with a conforming support 4. The lower end of the conforming support 4 is fixedly connected to the sliding beam seat 3, and the upper end is a conforming bracket 5. The shape of the conforming bracket 5 matches the curved surface segment 7, and the conforming bracket 5 is fixedly connected to the curved surface segment 7.

[0050] Example 2 of shelf fixture 1:

[0051] Because the curved sections 7 of the hull have various shapes from bow to stern, therefore, Figure 4 As shown, in this embodiment, when the bottom surface of each segment is entirely curved, the number of conformal support members 4 can be increased. In this embodiment, tube support members 38 are provided at both ends of the upper part of the sliding beam seat 3, providing two supports on the sliding beam seat 3. In order to avoid segmental deformation at the support position, wooden blocks can be inserted into the gaps to strengthen the support area and reduce the contact pressure.

[0052] In this embodiment, the conformal support 4 is a beveled surface 19 cut from the upper end of the tube support 38 to match the curvature of the surface at the support point. For example... Figure 4 As shown, in this embodiment, the upper end of the pipe support 38 is directly processed to form the support. The cutting angle of the beveled surface 19 matches the curved surface of the segment, which can increase the contact area and improve the support stability. The beveled surface 19 is welded and fixed to the segment to improve the firmness.

[0053] Example 3 of shelf fixture 1:

[0054] like Figure 5 As shown, the sliding beam seat 3 in this embodiment is the same as that in the previous embodiment, except that the top of the upper conformal support 4 is provided with a conformal bracket 5 as a support point.

[0055] Specifically, the conformal support 4 includes a horizontal plate 20 set on the upper end of the tube support 38, and a vertical plate 21 is vertically set on the horizontal plate 20. The vertical plate 21 facing the curved surface segment 7 has a beveled surface 19 processed according to the curvature of the curved surface at the support point. Triangular ribs 18 are provided on both sides of the vertical plate 21. The advantage of this embodiment is that the shape of the fitting line between the vertical plate 21 and the outer curved surface of the segment is easy to cut and process, and the multiple triangular ribs 18 can effectively supplement the rigidity of the lateral support. Furthermore, the welding line between the vertical plate 21 and the segment is relatively straight, which facilitates welding and subsequent cutting and dismantling.

[0056] The pipe support 38 or the vertical plate 21 is provided with a transport column 22 parallel to the sliding beam seat 3. The transport column 22 is welded to the surface of the curved segment 7 with a beveled surface 19 at one end. Figure 5As shown, in this embodiment, a transport column 22 is added to facilitate welding and fixing of such high sections during movement, preventing them from tipping over and improving safety during transport.

[0057] Example 1 of track platform 2:

[0058] Track platform 2, such as Figures 6-8 As shown, at least two sliding tracks 6 are provided in parallel. The sliding beam seat 3 is slidably connected and placed in the sliding track 6. The sliding beam seat 3 can be placed in or removed from the sliding track 6 at any position above the sliding track 6.

[0059] Specifically, such as Figure 8 As shown, the sliding rail 6 has an "I"-shaped cross-section, including an upper rail surface 23. In this embodiment, the sliding rail 6 can also be processed using I-beams. A lower rail surface 24, a rail support plate 25 is vertically arranged between the upper rail surface 23 and the lower rail surface 24. Multiple reinforcing ribs 14 are provided on both sides of the rail support plate 25. Round steel bars 8 are arranged inside the sliding rail 6, with the axis of the round steel bars 8 perpendicular to the axis of the sliding rail 6. The arrangement of the round steel bars 8 allows for rolling contact between the shelf fixture 1 and the rail platform 2, facilitating segmented lateral sliding. Rail baffles 9 are vertically arranged on both sides of the sliding rail 6 along its length. The sliding rail 6 is mounted on the support frame 10. Specifically, the track baffle 9 includes an inner baffle 26 and an outer baffle 27. The inner baffle 26, the upper track surface 23, and the outer baffle 27 are arranged in a U-shape, forming an axially oriented elongated opening on the upper side of the sliding track 6. This open design allows the sliding beam seat 3 to be easily placed into the track at any position and moved. Figure 6 , 8 As shown, the sliding track 6 is also provided with a hoisting limit plate 28. There are at least two hoisting limit plates 28 at corresponding positions on each sliding track 6. The hoisting limit plate 28 is a vertical plate that is fixedly installed on the outside of the sliding track 6 and extends outward and upward. The hoisting limit plate 28 extends upward and is higher than the sliding beam seat 3. Thus, when docking, a stop bar can be provided at the hoisting limit plate 28 to prevent automatic sliding when the segmented hoisting enters the sliding track 6. When the manual hoist for traction is set, the stop bar is removed, and the segmented lateral movement is pulled by active traction.

[0060] Due to the complex ground conditions within the dock, with many supports in some areas, when there are no protruding supports at the location of the displacement, a method such as... Figure 6The shown support frame 10, with two said sliding tracks 6 arranged on the connected support frame 10. The support frame 10 includes column supports 35, longitudinal diagonal braces 36, and transverse diagonal braces 37. Below each of the two sliding tracks 6, there are multiple column supports 35. Between the column supports 35 on both sides, there are transverse diagonal braces 37 arranged in an X-shaped cross, and longitudinal diagonal braces 36 are provided between the columns on the same side. By Figure 6 As shown in the three views, longitudinal diagonal braces 36 are obliquely arranged between the column supports 35 on the same side, and transverse diagonal braces 37 that are connected to each other are arranged between the column supports 35 on both sides. As shown in the actual drawing, they enclose a shape like the Chinese character 'Ri', thus having better stable support performance.

[0061] Embodiment two of the track platform 2:

[0062] When there are many piers in the dock, it is not convenient to directly connect between the column supports 35 on both sides. As Figure 9 shown, it is the three views of one side of the sliding track 6 and the corresponding column support 35. In this embodiment, the structure of the longitudinal diagonal brace 36 is the same as that in the previous embodiment, the difference being that the transverse diagonal brace 37 is independently arranged and supported on the ground to form a triangular stable support; the advantage of this embodiment is that it is convenient to erect along the gaps between the piers where there are many piers.

[0063] As Figure 7 shown, find the hull base surface on the column support 35 and make center punch marks at the corresponding positions for subsequent translation operations.

[0064] As Figure 12 shown, in some embodiments, round steel 8 is arranged loosely in the sliding track 6. When translating the segment, it is necessary to continuously add round steel 8 in front of the moving direction in the sliding track 6. This is rather cumbersome, and if the added round steel 8 rotates horizontally on the upper track surface 23, the rolling support effect is lost, and the contact friction force suddenly increases.

[0065] As an improvement, as Figure 10 shown, in this embodiment, both ends of each round steel 8 are arranged and connected through a winch chain 29 to form an entire heavy-duty roller chain similar to a chain. At both ends of the sliding track 6, wide-width sprockets 30 are respectively rotatably connected. The width of the wide-width sprocket 30 matches the length of the round steel 8. In actual use, the round steel 8 is stuck into the teeth of the wide-width sprocket 30. Not only can it pull the movement of the entire wide-width sprocket 30 as the segment is translated, but through the limit of the winch chain 29, each round steel 8 can be kept parallel and will not twist in the horizontal direction; thus ensuring a good rolling effect.

[0066] Below both ends of the sliding track 6, there are respectively provided winding mechanisms 31. As Figure 10As shown, the heavy roller chain moves to the right with the movement of the segment, at which time the right side winding mechanism 31 winds, while the left side unwinds, and vice versa before the segment enters the sliding rail 6, so that the tool can be repeatedly used. The winding shaft mechanism includes a winding shaft 32 and a winding baffle 33, as shown Figure 13 、 14 As shown, the winding shaft 32 is provided with a winding baffle 33 at one end, and two winding baffles 33 are provided in parallel, and the spacing between the two winding baffles 33 is matched with the width of the heavy roller chain, so that the heavy roller chain can be neatly wound between the two winding baffles 33, and the winding shaft 32 is provided with a long through hole 34 for the sprocket to pass through, and the long through hole 34 is arranged between the two winding baffles 33. The long through hole 34 is for the end of the heavy roller chain to pass through, and the end of the heavy roller chain is fixed by rotating the winding shaft 32.

[0067] A method for using a curved segment 7 in-dock translation tool, as shown in Figure 11 、 12 The method comprises the following steps:

[0068] S1, segment tool, processing the rack tool 1 at the hull curved segment 7 jig, installing two I-beams at the lower opening of the curved segment 7 to form a reference plane according to the center of gravity of the segment, to ensure that the segment can be placed stably, and the I-beams are used to make the sliding beam seat 3;

[0069] According to the width and weight of the segment, the length of the sliding beam seat 3 tool is determined;

[0070] During the segment manufacturing stage, the I-beam plane is determined to be parallel to the theoretical hull base plane for segment positioning, and a profiled support 4 is welded on the upper surface of the I-beam;

[0071] S2, in-dock tool, determine the platform length by simulating the horizontal translation distance of the segment through the segment lifting point; to avoid collision during the segment translation process, the platform height is 100mm lower than the theoretical installation height of the segment; according to the layout of the hull support in the dock, an independent support frame 10 or a connected support frame 10 is selected;

[0072] Weld the sliding rail 6 on the support frame 10, and design rail baffles 9 on both sides of the sliding rail 6 to avoid derailment during the segment translation process;

[0073] S3, after the ship enters the dock, according to the original ship center, rib position and ship bottom base plane, the in-dock tool is welded on the dock deck corresponding to the segment tool;

[0074] S4, the segment is lifted on the sliding rail round steel 8 of the tool sliding rail 6, and is slowly translated into the ship under the cooperation of the dock crane;

[0075] S5, using the handle gourd or jack to lift the section to the installation position, trim the excess amount, and complete the assembly.

[0076] Where the maximum section curved line type, the highest installation position (joint distance to the deck 7.5 meters), the largest tool, about 12 tons of 823 / 833 section in the whole implementation of the use of the process, only 15 minutes of translation time, the whole lifting process 30 minutes dock crane hook, 60 minutes section in place, the rest of the section to achieve the goal of 30 minutes hook, 10 days to complete the lifting of all sections, achieved good results, for the project dock period control laid the foundation.
