Chain stopper reinforced connection structure

Abstract

The present invention relates to the technical field of installation and positioning of deck chain stoppers, and discloses a reinforced connection structure for chain stoppers, including: a deck surface, and a well truss is welded to the bottom of the deck surface. With this new form of reinforced connection for chain stoppers, by providing a well truss and a through groove, after misalignment occurs between the chain stopper and the reverse side reinforcement, the sliding seat can be slid according to the installation position of the chain stopper, thereby correspondingly adjusting the position of the base, enabling the old-fashioned overhead welding on the reverse side of the deck to be changed to construction on the front side of the deck, increasing the convenience of chain stopper installation. At the same time, using the sliding seat to control the movement of the base and the positioning structure to control the fixation of the base, the base can still be adjusted after the deck is loaded, avoiding the problems of cable, pipe system, and bracket intersecting longitudinal girders on the reverse side of the deck and having no construction space, avoiding high-altitude operations on the reverse side of the deck, reducing the construction risk, changing to normal construction, and having a good construction environment, which is conducive to ensuring the construction quality.

Description

Technical Field

[0001] The invention relates to the technical field of deck chain stopper installation and positioning, in particular to a chain stopper reinforcement connection structure. Background Art

[0002] At present, when a ship drops anchor, the anchor chain will be subjected to huge pulling force due to the weight of the ship itself and the influence of various factors such as water and wind. In order to withstand the huge pulling force and fix the ship, the ship needs to install an anchor chain stopper to protect the transmission shaft of the anchor machine, thereby reducing the pulling force on the anchor machine and its base when dropping anchor.

[0003] After the chain stopper is installed, its reinforcement base and reinforcement plate are located on the reverse side of the deck to improve the tensile strength of the chain stopper. The reinforcement base and reinforcement plate of the chain stopper are generally installed in advance in the segmented stage of the ship production process. After the deck is loaded, the chain stopper will be installed on the deck surface. Because it needs to cooperate with the anchor pulling effect and the gate knife's clamping effect, the chain stopper needs to adjust its position. Therefore, every ship has a situation where the chain stopper and the reverse reinforcement are misaligned. At present, when the chain stopper is misaligned with the reverse reinforcement of the deck, the welding part of the reinforcement base on the reverse side of the deck needs to be planed open, and then repositioned and welded. After the loading stage, the position of the reinforcement base needs to be adjusted again, which requires scaffolding to be lapped and overhead welding to be carried out. Construction on the reverse side of the deck is not only in a small space, but also requires high-altitude operations, which greatly increases the construction risks of construction personnel and affects the construction and production progress. Summary of the invention

[0009] Preferably, the side of the limiting block away from the base is arc-shaped, and the center of the arc on the side of the limiting block corresponds to the center of the shaft rod.

[0010] Preferably, trapezoidal reinforcing ribs are arranged on the top of the reinforcing base platform, and the reinforcing ribs on the top of the reinforcing base platform correspond to the positions of the reinforcing ribs on the side of the chain stopper body.

[0011] Preferably, two clamping bars are welded to the surface of the deck surface, the two clamping bars are respectively located on both sides of the through groove, and a reinforcing steel bar is welded between the two clamping bars.

[0012] Preferably, a positioning steel plate is slidably connected to the inner wall of the clamping bar, and one end of the positioning steel plate close to the base abuts against the bottom of the reinforcing base platform.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. For this new chain stopper strengthening connection form, by providing the well truss and the through groove, after misalignment occurs between the chain stopper and the reverse side reinforcement, the sliding seat can be slid according to the installation position of the chain stopper, so as to correspondingly adjust the position of the base, enabling the old reverse side fillet welding of the deck to be changed to the front side construction of the deck, increasing the convenience of chain stopper installation. At the same time, by using the sliding seat to control the movement of the base and the positioning structure to control the fixation of the base, the base can still be adjusted after being mounted on the deck, avoiding the problems of intertwined cables, pipe systems, and brackets on the reverse side of the deck and the lack of construction space, avoiding high-altitude operations on the reverse side of the deck, reducing the construction risk, changing to normal construction, and having a good construction environment, which is conducive to ensuring the construction quality.

[0017] 2. For this new chain stopper strengthening connection form, by providing the positioning structure, the position of the base is fixed by the nuts and positioning blocks at both ends of the positioning structure. At the same time, by adjusting the positions of the nuts at both ends of the positioning structure to different positions, the base can be slightly rotated depending on the thrust and fixing degree between the clamping plate and the positioning block, enabling the base to be adjusted according to the orientation of the chain stopper positioning after being mounted on the deck, thereby increasing the accuracy of the chain stopper body installation after installation and reducing the influence of the skewing force on the chain stopper.

Detailed Embodiment

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figure 1-6 , the chain stopper strengthening connection structure includes: a deck surface 1, a well truss 6 is welded to the bottom of the deck surface 1, a through groove 10 is formed on the surface of the deck surface 1, the size of the inner wall of the through groove 10 corresponds to the size of the inner wall of the well truss 6, a sliding rod 8 is welded to the inner wall of the well truss 6, a sliding seat 9 is slidably connected to the outer edge of the sliding rod 8, a base 4 is arranged on the top of the sliding seat 9, a sliding groove 11 is formed on the inner wall of the well truss 6, a limiting block 14 is slidably connected to the inner wall of the sliding groove 11, the limiting block 14 is welded to the side of the base 4, a strengthening base 15 is arranged on the side of the base 4 near the top, a chain stopper body 5 is welded to the top of the base 4, and a positioning structure 16 is arranged on the side of the base 4.

[0027] Among them; a reinforcing plate 7 is welded to the outer edge of the well truss 6. The reinforcing plate 7 is a triangular reinforcing rib plate, and the reinforcing plate 7 is welded at the angle between the deck surface 1 and the well truss 6. Fixing the well truss 6 by using the reinforcing plate 7 can further improve the stress capacity of the well truss 6, thereby making the base 4 of the chain stopper more stable.

[0028] Among them; the width of the sliding seat 9 is adapted to the width of the inner wall of the well truss 6. As Figure 2 shown, reducing the distance between both sides of the sliding seat 9 and the side surface of the inner wall of the well truss 6 enables the sliding seat 9 to be directly full-welded to the inner wall of the well truss 6 after the adjustment and calibration are completed, further increasing the stability of the base 4.

[0029] Among them; a through hole 13 is opened on the surface of the base 4, and a shaft rod 12 is rotatably connected to the inner wall of the through hole 13. The shaft rod 12 is welded to the top of the sliding seat 9. As Figure 4 shown, opening the through hole 13 at the center of the surface of the base 4 enables the base 4 to have the ability to rotate. At the same time, the top of the through hole 13 is open, so that after the adjustment and calibration of the base 4 are completed, it can be directly welded to the sliding seat 9, and then the base 4 is fixed. At the same time, the welding of the sliding seat 9 can further increase the load-bearing capacity of the base 4.

[0030] Among them; the side of the limiting block 14 away from the base 4 is set to be arc-shaped, and the center of the arc on the side surface of the limiting block 14 corresponds to the center of the shaft rod 12. As Figure 5 shown, the limiting block 14 arranged on the side of the base 4 has a center of the arc on its surface that can always keep the arc surface in full contact with the inner wall of the sliding groove 11 as the base 4 rotates, thereby increasing the firmness of the base 4 after installation and reducing the probability of the base 4 shaking during adjustment.

[0031] Among them; trapezoidal reinforcing rib plates are arranged on the top of the strengthening base 15, and the reinforcing rib plates on the top of the strengthening base 15 correspond to the positions of the reinforcing rib plates on the side of the chain stopper body 5. By welding the reinforcing rib plates on the top of the strengthening base 15 and the side of the chain stopper body 5, the stress area during the installation of the chain stopper body 5 is increased. At the same time, the trapezoidal reinforcing rib plates arranged on the top of the strengthening base 15 can provide a supporting force for the side of the base 4, enabling the base 4 to be completely butted and installed with the chain stopper body 5.

[0032] Among them; two clamping strips 2 are welded to the surface of the deck surface 1. The two clamping strips 2 are respectively located on both sides of the through groove 10, and a reinforcing steel bar is welded between the two clamping strips 2. By adding the clamping strips 2 to reinforce the periphery of the base 4 later, the base 4 can fill the reserved hole of the well truss 6 after installation.

[0033] Among them, a positioning steel plate 3 is slidably connected to the inner wall of the clamping strip 2. One end of the positioning steel plate 3 close to the base 4 overlaps with the bottom of the strengthening base platform 15. The positioning steel plate 3 is locked on the deck surface 1 through the clamping strip 2, and then one end of the positioning steel plate 3 is used to support the strengthening base platform 15. At the same time, it can be welded later to provide an additional load-bearing structure for the base 4.

[0034] Among them, the positioning structure 16 includes a rotating block 161. Screws 162 are welded on both sides of the rotating block 161. A clamping plate 164 is slidably sleeved on the surface of the screw 162. A positioning block 165 is welded on one side of the clamping plate 164, and a nut 163 is arranged on the other side of the clamping plate 164. By adjusting the position of the nut 163, the fixed positions of the positioning blocks 165 at both ends of the rotating block 161 change. Subsequently, the base 4 will be stressed and rotate slightly. The orientation angle of the chain stopper body 5 can be adjusted by using the rotation of the base 4, thereby increasing the accuracy after the installation of the chain stopper body 5.

[0035] Among them, the length and height of the positioning block 165 respectively correspond to the width and height of the inner wall of the sliding groove 11. By making the positioning block 165 fully contact with the inner wall of the sliding groove 11, and at the same time using the clamping plate 164 to increase the contact area of the positioning block 165, the positioning block 165 can fix the base 4 under the control of the nut 163, and at the same time facilitate the full welding after the subsequent adjustment is completed.

[0036] Working principle: After the deck loading stage, when installing the chain stopper, first use a heavy object to simulate the route of the chain when the ship's anchor is dropped. Then, according to the simulation situation, slide the sliding seat 9 below the chain route. Then, according to the chain orientation, turn the corresponding nut 163. The thrust generated by the combination of the nut 163 and the clamping plate 164 is used to push the screw rod 162 and the rotating block 161, causing the rotating block 161 to rotate at both ends of the base 4, thereby changing the angle of the base 4. At the same time, the through hole 13 on the surface of the base 4 and the shaft rod 12 on the surface of the sliding seat 9 can stably control the rotation orientation of the base 4 to prevent the base 4 from shifting during rotation. After the angle of the base 4 is adjusted, tighten the corresponding nuts 163 at both ends of the same rotating block 161 to fix the base 4. At this time, align the chain stopper body 5 with the top of the base 4 and weld it. Then, use the ship's anchor simulation on the chain stopper body 5 again to ensure that the position of the chain stopper body 5 is adjusted. If there is a deviation, adjust it again according to the above steps and then re-simulate. If there is no deviation, take the welding tool and fully weld the sliding seat 9 to the inner wall of the well truss 6 and the surface of the sliding rod 8 respectively. Then, weld the sliding seat 9 to the base 4 through the shaft rod 12. Subsequently, continue to weld all the movable components on the positioning structure 16 to further improve the stability of the base 4. Finally, use the sliding of the positioning steel plate 3 on the inner wall of the clamping strip 2 to make the positioning steel plate 3 slide below the strengthening base 15, and weld the positioning steel plate 3 to the strengthening base 15 and the clamping strip 2 respectively, so that the installation holes reserved on the deck surface 1 are filled, and at the same time, the firmness between the chain stopper body 5 and the base 4 can be further increased.
