Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding, and in particular to a reusable curved segmented active support tool and application thereof. Background Art

[0002] When modern advanced shipbuilding companies plan and construct the construction process, straight sections generally adopt a production line layout; curved sections and large assembly sections are generally built in a fixed area, commonly known as position construction. When the number of positions is fixed, speeding up the cycle of positions and reducing the time for erection and disassembly of positions has become the most effective way to increase the number of sections built.

[0003] During the construction of the shipyard, the curved segmented construction position is usually supported by flexible supports to ensure the linear shape of the outer plate. That is, the flexible support fixing base is welded and fixed at a spacing of 1 meter on the surface of the embedded steel plate of the cage, and the support rod is installed on the upper part of the base. The rotating head is installed at the end of the support rod, and the end height is fine-tuned by the rotating head to ensure that the design support requirements are met. When the adjustment height of the rotating head cannot meet the height adjustment requirements, the support rod needs to be replaced and the height adjustment needs to be achieved in conjunction with the rotating head. A connecting rod of about 1 meter is also required between the horizontal and vertical directions to connect and fix the two adjacent support rods together to keep the support rods relatively fixed.

[0004] However, in actual use, since the flexible supports are installed and arranged with equal spacing in the horizontal and vertical directions, when constructing a large curved segment of 18 meters by 16 meters, at least 288 flexible supports need to be installed, and the height of each support needs to be adjusted to the size required by the drawings. At the same time, connecting rods of about 1 meter are used to fix each other, and about 442 connecting rods need to be installed, which consumes a lot of manpower and takes a long time. This part of time is the invalid time of the fetal position. The shorter the invalid time, the more helpful it is to increase the number of segment construction. In addition, when constructing the next curved segment, the original support needs to be adjusted or dismantled, and the flexible support that meets the design height needs to be re-erected. Although the centralized construction of the same segments in actual use can also reduce the frequency and time of adjusting the flexible supports, even for mass product construction, the adjustment frequency of the flexible supports is still very high due to the limitations of storage site resources, storage cycle, and the order of use of the segment assembly, and the labor and time consumed are still high.

[0045] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0046] The present embodiment discloses a reusable curved segmented flexible support tooling, comprising a plurality of fixed bases, flexible supports and a quick assembly positioning tire frame.

[0048] The outer diameter of the active support is set to 83mm and the wall thickness is set to 8mm, including a support rod 21 and an adjustment rod 28. The support rod is as follows Figure 3As shown, a fixed wire rotating block 23 is arranged on the top of the support rod, an external rotating block 22 is arranged on the fixed wire rotating block 23, the fixed wire rotating block 23 is threadedly connected to the external rotating block 22, a semicircular rotating head 24 is connected to the top of the external rotating block, a rotating hole 25 is arranged on the rotating head 24, and a steel column is passed through the rotating hole to adjust the height of the rotating head. Multiple pairs of supporting holes 26 are arranged at equal intervals along the axial direction of the support rod on both sides of the support rod. In this embodiment, the diameter of the supporting hole is set to 22mm, the vertical spacing between two adjacent supporting holes is 100mm, and the distance between the supporting hole at the bottom of the support rod and the bottom end of the support rod is 100mm; a conical head 27 is arranged at the bottom of the support rod, the length of the conical head is set to 50mm, the diameter gradually decreases from top to bottom, and the lowest end diameter is 43mm, which can facilitate the bottom of the support rod to be introduced into the mounting groove of the fixed base. The adjusting round rod 28 is matched with the supporting hole 26 of the supporting rod, and is used to pass through the supporting hole to support the supporting rod on the fixed base. The active supports on adjacent fixed bases are connected by connecting rods 29 in the original design and use to fix adjacent active supports. However, too many are installed, and the fetal position is occupied for too long. Figure 4 In the present invention, a special tool 3 is used to pre-install the flexible support on the quick assembly positioning tire frame 6 in advance, and when in use, the special tool 3 is used to fix it longitudinally on the fetal position.

[0049] In order to meet the requirements of support height, the present embodiment is equipped with flexible supports of various lengths, but the size specifications of the support hole in the support rod, the fixed wire rotating block, the external rotating block and the rotating head in the flexible supports of different lengths are the same. After the support rod is fixed to the fixed base by passing the adjusting round rod 28 through the support hole, the rotating head on the support rod is adjusted to a preset height according to the design drawing. If the height of the rotating head after adjustment cannot meet the preset height requirement, the support height of the flexible support is made to meet the requirements of the design drawing by adjusting the position of the support hole through which the adjusting round rod 28 passes or replacing flexible supports of other height sizes.

[0050] The special tooling 3 is made of channel steel. Figure 5As shown, the size of the channel steel is 200mm×73mm×9mm, and a plurality of pairs of arc holes 31 are arranged at equal intervals at relative positions on both side walls of the trough body of the special tooling. The spacing between adjacent arc holes on the same side wall is 1m, the arc radius of the arc hole 31 is set to 41.5mm, and the arc depth is set to 15mm.

The support rod of the active support is embedded in two arc holes 31 arranged oppositely in the special tooling, and the same pair of positioning holes 32 are respectively located on both sides of the support rod. The U-shaped screws 33 are sequentially passed through the positioning holes 32 on both sides of the support rod, and the two ends of the U-shaped screws are respectively fixed with nuts 34, so that the support rod and the special tooling are relatively fixed to form a whole. Figure 6 shown.

[0051] The rapid assembly positioning tire frame 6 is as follows Figure 7 As shown, it includes a bottom plate 60, a limiting column 65, a plurality of vertical column channel steels 61 and a plurality of transverse connecting channel steels 63, wherein the vertical column channel steel 61 is made of a channel steel with a size of 200mm×73mm×9mm, and the transverse connecting channel steel 63 is made of a channel steel with a size of 100mm×50mm×5mm. The limiting column 65 and the vertical column channel steel 61 are both fixed to the bottom plate, and a reinforcing plate 66 for support is provided at the bottom of the vertical column channel steel 61. A limiting column 65 is provided on one side of the quick assembly positioning tire frame 6, and a plurality of vertical column channels are provided at intervals on one side of the limiting column 65. Steel 61, the spacing between two adjacent vertical column channel steels is 1000mm, and the distance between the vertical column channel steel 61 closest to the limit column 65 and the limit column 65 is 600mm, and a plurality of transverse connecting channel steels 63 are arranged in the vertical direction of the vertical column channel steel 61, and the ends of the transverse connecting channel steels 63 are fixed to the limit column 65, and the distance between the upper surface of the bottom transverse connecting channel steel and the bottom plate surface is 700mm. In this embodiment, the distance between the upper and lower adjacent transverse connecting channel steels 63 is determined according to the gap between the positioning plates 62, which plays a role in fixing the vertical column channel steel 61.

[0052] A plurality of positioning plates 62 are arranged at equal intervals on the front side of the bottom plate of the trough body of the vertical column channel steel 61. The slope angle between the positioning plates 62 and the bottom plate of the vertical column channel steel 61 is 50°, and the distance between two adjacent positioning plates is 600 mm. The special tooling is installed on the positioning plates and is tightly attached to the vertical column channel steel 61 for subsequent installation and fixing of the flexible support 2. A pedestrian platform 64 is arranged on the back side of the bottom plate of the trough body of the vertical column channel steel 61.

[0053] The limiting block 5 is fixed on the side wall of the channel body of the vertical column channel steel 61. Figure 8 As shown, the outer width of the slot body of the limit block is set to 27mm and the length is set to 60mm, the inner length of the slot body is set to 44mm and the width is set to 11mm, and the slot body width is set to 20mm. The surface of the limit block 5 is provided with a scale line 51, and the setting length of the limit block is determined according to the height of the quick assembly positioning tire frame. The zero scale of the scale line on the limit block 5 is flush with the upper surface of the transverse connecting channel steel 63 at the bottom of the quick assembly positioning tire frame 6. The limit block 5 is connected to the mobile module 4, and the mobile module 4 includes an arc block 40, a long block 41 and a limit rod 44, as shown in FIG. Fig. 9 As shown, the length of the long block is 200mm, the width is 42mm, and the thickness is 10mm. One side of the arc block of the mobile module 4 is fixed to the long block, and the other side is connected to the limit rod 44. The top of the arc block 40 and the bottom of the limit rod 44 are both provided with height measurement lines. The long block 41 of the mobile module 4 is embedded in the limit groove on the outside of the limit block 5, moves up and down along the axis of the limit groove, and is fixed in the limit block 5 by a butterfly screw 43. Threaded holes 42 are provided at both ends of the long block of the mobile module 4, and an arc block 40 is fixed at the middle position. The threaded hole 42 is 15mm away from the top edge of the long block and 21mm away from the edges on both sides of the long block. The arc side of the arc block 40 protrudes outward, and the butterfly screw 43 passes through the threaded holes provided at the end of the limit rod and the top surface of the arc block 40 in turn to thread the arc block 40 and the limit rod. The limit rod 44 can be rotated and fixed with the butterfly screw 43 as the center of the circle. Fig.10 shown.

[0054] The application process of a reusable curved segmented flexible support tooling proposed in this embodiment is as follows:

[0055] Fig.11The figure shows the assembly drawing of the quick assembly positioning frame and the flexible support of the present invention. The special tool is hoisted and installed on the positioning plate of the quick assembly positioning frame, and the special tool is placed on the positioning plate so that the special tool is in close contact with the vertical column channel steel, and the end of the special tool is in close contact with the limit column, ensuring that the two ends of multiple special tooling are placed in the corresponding arc holes. According to the size requirements of the design drawing, adjust the height measurement line of the mobile module to the scale corresponding to the preset height of the limit block, and use butterfly screws to fix the long block of the mobile module at the preset position. Adjust the position of the limit rod and fix it with butterfly screws to adjust the reference object that meets the design height. Similarly, adjust the limit rods of the mobile modules in all vertical column channel limit blocks to the design height. Then, for the active supports used at each position, roughly select active supports of appropriate height, pass the adjusting round rod 28 through the supporting hole of the supporting rod in the active support, and support the adjusting round rod 28 on the upper surface of the transverse connecting channel steel at the bottom of the quick assembly positioning tire frame, and judge whether the top of the rotating head can be adjusted to the lower surface of the limit rod by adjusting the rotating head of the support rod. If the top of the rotating head can be adjusted to the lower surface of the limit rod by adjusting the rotating head of the support rod, use U-shaped screws and matching nuts to fix the support rod on the special tooling, otherwise, use the support holes at other positions on the support rod to support the adjustment Round rod, but the maximum adjustment size should not be greater than the height of the fixed base. Since the distance between the upper surface of the bottommost transverse connecting channel steel and the bottom plate is 700mm, the lower extension of the active support is limited by the bottom plate. At this time, it will be impossible to achieve subsequent assembly by replacing and adjusting the round rod support position. It is necessary to replace the remaining length of the active support to achieve the coordination of the active support and the quick assembly positioning frame. By adjusting the length of the active support, the position of the selected support hole and the rotation angle of the rotating head, the active support that meets the design requirements at each support position is determined, and each active support is pre-installed and connected with special tooling to form a Fig.12 The transverse integral frame flexible support 7 shown in the figure realizes the pre-installation of the flexible support. At the same time, the number of each pre-installed transverse integral frame flexible support is determined, and each transverse integral frame flexible support is numbered in the manner of "segment number + sequence number". For example, the transverse integral frame flexible support of the first row of the 1334 segment is 1334-1, the transverse integral frame flexible support of the second row is 1334-2, and the others are named 1334-3, 1334-4... in sequence. The transverse integral frame flexible support 7 in this embodiment can be stored upright or stacked flatly, which saves storage space.

[0056] When in use, install the pre-installed horizontal integral frame flexible supports in the order of numbers, and use the guiding function of the conical heads at the bottom of each flexible support to quickly insert them into the fixed base. Fig.13As shown, at the same time, each active support is supported on the top surface of the fixed base by adjusting round rods to complete the installation of the horizontal overall frame active support, and then each active support is fixed on the special tooling 3 by using U-shaped screws 33 and matching nuts 34, and the special tooling is fixed in the longitudinal direction to complete the curved segmented active support tire.

[0057] After the reusable curved segmented flexible support tooling in this embodiment is used, the U-shaped screws and the nuts used in conjunction are removed, the special tooling installed in the longitudinal direction is removed, and then the flexible supports are removed in sequence according to the numbers and the horizontal integral frame flexible support 7 is stored, and it will be assembled and used again when the same type of segmented support is needed next time. If there is no need for the same type of segmented support for a long time, the flexible supports in the horizontal integral frame flexible support 7 are disassembled and assembled into supports of other required types of segmented support.

[0058] It can be seen that the reusable curved segmented active support tooling proposed in the present invention occupies the fetal position only when the horizontal overall frame active support is installed and the longitudinal special tooling is fixed. Compared with the prior art method of directly installing nearly three hundred active supports and more than four hundred connecting rods by occupying the fetal position for support and fixation, the reusable curved segmented active support tooling proposed in the present invention greatly reduces the invalid time of occupying the fetal position, greatly improves the utilization efficiency of the fetal position, and increases the segmented output.

[0059] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not a limitation of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the protection scope of the present invention.
