Description

Technical Field

[0001] The invention relates to the technical field of glass fiber reinforced plastic ship testing, in particular to a device for testing the oblique tension of a connection node of a glass fiber reinforced plastic ship. Background Art

[0002] FRP boats are different from other ships. They need to be initially coated with a paint layer in a prefabricated mold, and glass-reinforced fiber plastic is evenly laid in the paint layer. The glass-reinforced fiber plastic is bonded with glue until it solidifies. When the prefabricated mold is disassembled, the rough blank of the FRP hull can be formed. Because it has superior performance over metal materials, it is widely used in military and civilian fields.

[0003] Since the most basic components of different types of FRP boats are the hull, deck, hull and cabin, the deck installed on the top of the hull needs to be fixed and sealed by self-tapping screws, expansion agents and structural adhesives, and most of these connection points are T-shaped structures, and this kind of gluing and other operations need to rely on manual operation. After the expansion agent and structural adhesive form the gap between the side of the ship and the hull, the bulge formed at the connection node is difficult to carry out compression testing, so the stability of the deck and bulkhead after installation on the hull and the looseness of the gap are difficult to detect.

[0004] In view of this, a fiberglass reinforced plastic ship connection node oblique tension test device was designed to solve the above problems. Summary of the invention

It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0054] A device for testing the oblique tension of a fiberglass reinforced plastic ship connection node provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0055] Embodiment 1:

[0056] Combination Figure 1-Figure 12 As shown, a fiberglass ship connection node oblique tension test device provided by the present invention includes two reinforced suction cups 200, an angle adjustment mechanism 100 arranged on the two reinforced suction cups 200, a guide pressure mechanism 300 arranged on the angle adjustment mechanism 100, a side testing mechanism 400 arranged on the guide pressure mechanism 300, and a cable 500 arranged on the side testing mechanism 400, the angle adjustment mechanism 100 is used to provide a stable testing support platform for the side testing mechanism 400, the two reinforced suction cups 200 are used to support the angle adjustment mechanism 100, the guide pressure mechanism 300 is used to control the inclination angle of the side testing mechanism 400 and adapt to structural seams of different sizes, and the side testing mechanism 400 is used to perform compression testing on the splint and the side of the ship.

[0057] The angle control mechanism 100 includes two first screw sleeves 140, a first limit beam plate 110 movably mounted on one of the reinforcing suckers 200, and a second limit beam plate 120 movably mounted on the other reinforcing sucker 200. A distance control screw rod 150 and two clamping seats 160 are movably mounted in the first screw sleeve 140.

[0058] The first limiting beam plate 110 and the second limiting beam plate 120 are both provided with transverse grooves inside, and the adjacent ends of the first limiting beam plate 110 and the second limiting beam plate 120 are provided with combined bolts 130;

[0059] Two clamping seats 160 are arranged on the sleeve, and the two clamping seats 160 are clamped on the column heads at the inner ends of the distance control screw rods 150;

[0060] The two reinforced suction cups 200 are used to absorb and fix the outer wall of the hull and provide a sufficiently stable support force for the angle control mechanism 100;

[0061] The guide pressure mechanism 300 includes a pad 310 disposed between the first limiting beam plate 110 and the second limiting beam plate 120, a guide rail 350 is movably mounted on the pad 310, and a sliding groove 370 with a triangular structure is provided inside the guide rail 350;

[0062] The side testing mechanism 400 includes a fixture 430, a slide post 420 movably mounted in the slide slot 370, a pressure-bearing component 410 mounted on the top of the slide post 420, and a pressurizing component 460 for applying pressure to the structural joint for testing is mounted on the pressure-bearing component 410;

[0063] A horizontal hydraulic component 440 is installed in the clamp 430, and a baffle 450 is installed on the hydraulic sub-rod in the hydraulic component 440;

[0064] The baffle plate 450 is disposed on top of the push plate 462;

[0065] The cable 500 is mounted on the footing of the outer wall of the fixture 430;

[0066] The cable 500 is connected to an external traction device and provides oblique pressure to the side testing mechanism 400.

[0067] Since the FRP hull needs to be prefabricated inside a mold, once the FRP hull is made, it is necessary to use lifting equipment to fix the components such as the plywood, bulkhead and hull on the top of the hull in steps. After the installation of the various components of the lever, the fixed parts need to be fixed with self-tapping screws and structural adhesives, and the exposed gaps need to be filled with expansion agents. However, the above operations need to be done manually. After the structural adhesive and expansion agent are filled, due to the influence of the depth of the syringe inserted into the structural seam, there will be gaps inside the solidified glue and expansion agent, which will affect the firmness of the plywood or the hull.

[0068] The device is fixed on the outer wall of the glass hull by free adsorption. When the two reinforcing suction cups 200 are fixed, the angle control mechanism 100 as a whole can be movably installed on the two reinforcing suction cups 200. By adjusting the angle extension of the first limiting beam plate 110 and the second limiting beam plate 120, the guide pressure mechanism 300 locked by the combination bolt 130 can drive the side test mechanism 400 to selectively adjust toward the structural seam.

[0069] Then, the second screw rod 330 is adjusted to rotate clockwise, so that the suspension 340 pushed by the second screw rod 330 can push the guide rail 350 toward the outer wall of the hull until it is close to the outer wall. At this time, the slide column 420 and the pressure-bearing component 410 movably installed in the slide groove 370 can be quickly aligned along the structural seam. After the first limiting beam plate 110 and the second limiting beam plate 120 drive the guide pressure mechanism 300 and the pressure-bearing component 410 to push upward, the bottom plate 411 and the booster rod 467 can be squeezed into the interior of the structural seam.

[0070] As the hydraulic component 440 operates, the internal hydraulic sub-rod will push the baffle 450 and the push plate 462 to extend outward, and finally the inclined arm 465 will push the booster rod 467 to apply a squeezing force to the structural seam. At this time, the gear pin block 413 can guide the booster rod 467 to apply a firm detection pressure to the structural seam.

[0071] When the preliminary inspection of the structural seam is completed, the teeth on the outer end of the booster rod 467 will be engaged in the structural seam, and then Li Yonggang's external traction equipment will stretch the cable 500. Finally, the tightened cable 500 will apply selective traction to the side test mechanism 400, and the side test mechanism 400 will perform tilted pressure inspection along the slide groove 370. At this time, the firmness of the hull, deck and hull installation parts can be tested.

[0072] Embodiment 2:

[0073] Combination Figure 9-12 As shown, based on Example 1, the pressure-bearing component 410 includes a bottom plate 411, a trapezoidal groove is provided at the top of the outer end of the bottom plate 411, and two slideways are provided on the inner wall of the trapezoidal groove;

[0074] A guide rod 412 is disposed in one of the slideways, a gear pin block 413 is disposed outside the guide rod 412, and two support rods 414 are movably mounted at both ends of the guide rod 412;

[0075] The two side walls at the outer end of the bottom plate 411 are provided with evenly distributed limiting slots, and the support rods 414 are adapted to be snapped into the limiting slots.

[0076] Preferably, the outer end of the bottom plate 411 is a flat structure for quick adaptation to the structural seam, wherein the gear pin block 413 is movably installed in the trapezoidal groove, and the top of the gear pin block 413 is provided with an inclined slope;

[0077] After the two support rods 414 are tilted along the two ends of the guide rod 412, the gear pin block 413 set on the guide rod 412 can be selectively adjusted in one of the slideways, and the two support rods 414 can be selectively clamped in the limiting slots at the outer ends of the bottom plate 411.

[0078] The booster assembly 460 includes a side seam base 461 disposed on the top of the bottom plate 411, a push plate 462 is movably mounted inside the side seam base 461, an insertion rod 463 is mounted on the outer end of the push plate 462, two rectangular sliders 464 are mounted on both ends of the insertion rod 463, and two inclined arms 465 are movably mounted on the insertion rod 463;

[0079] The bottom ends of the two oblique arms 465 are provided with end rods 466, and a booster rod 467 is provided on the end rods 466, and the booster rod 467 is located inside the trapezoidal groove;

[0080] The end rod 466 is movably mounted in another slideway;

[0081] The bottom of the outer end of the boost rod 467 is provided with an inclined surface adapted to bear pressure on the gear pin block 413;

[0082] The top of the outer end of the boost rod 467 is provided with a corrugated groove for increasing the friction resistance, and the top of the corrugated groove is provided with uniformly distributed teeth.

[0083] Preferably, the top inclined slope of the gear pin block 413 is adapted to fit the bottom inclined surface of the boost rod 467. When the gear pin block 413 is selectively adjusted in the trapezoidal groove, the extended boost rod 467 can be guided by the gear pin block 413 after the adjustment to increase the extension angle, so that the structural seams between the hull, the deck and the hull can be pressurized.

[0084] An insertion rod is installed at one end of the side seam base 461 away from the insertion rod 463, and both ends of the insertion rod are movably installed in slots on the inner wall of the side seam base 461. As the hydraulic component 440 operates, its internal hydraulic sub-rod will push the baffle 450 and the side seam base 461 to extend horizontally, and finally, with the guidance of the gear pin block 413, the booster rod 467 that is further pushed can expand the structural seam, so as to facilitate the insertion of the syringe into the gap, so as to improve the filling efficiency of the structural glue and the expansion agent into the structural seam.

[0085] After the rod structural adhesive and the expansion agent are cured, the above-mentioned pressure test can be used to test the firmness of the hull, deck and body.

[0086] Embodiment 3:

[0087] Combination Figure 2-Figure 10 As shown, on the basis of Example 1, a second screw sleeve 320 is provided in the end plate at the other end of the backing plate 310, a second screw rod 330 is movably installed inside the second screw sleeve 320, and a suspension 340 is movably installed at the inner end of the second screw rod 330;

[0088] Two clamps 360 are installed on the guide rail 350, and the two clamps 360 are movably installed on both ends of the suspension 340;

[0089] Two return springs 380 are disposed in the slide groove 370 , and adjacent ends of the two return springs 380 are pressed against two side walls of the slide post 420 .

[0090] Preferably, the guide rail 350 movably mounted on the pad 310 will approach the outer wall of the hull after being compressed, until the rubber pad at the bottom of the outer end of the guide rail 350 is pressed against the outer wall of the hull, the slide column 420 in the initial state is located in the middle of the slide groove 370, and the outer end of the pressure-bearing component 410 is inserted into the center of the structural seam, and the subsequent radial pressure test is performed for the booster component 460;

[0091] When the guide rail 350 is stable, an external traction device of the same specification tightens the cable 500. At this time, the side test mechanism 400 can be tilted and pressurized along the slide groove 370 as a whole. At this time, the firmness of the structural glue and the expansion agent in the structural seam can be tested in real time, and the degree of relaxation of the hull after curing can be pressure tested.

[0092] The top and bottom surfaces of the pad 310 are provided with hemispherical slots distributed in a circumference;

[0093] The bottom of the inner end of the first limiting beam plate 110 and the top of the inner end of the second limiting beam plate 120 are both provided with a column head adapted to the hemispherical slot;

[0094] Air pipes and T-shaped columns are disposed in the two reinforced suction cups 200 , and sleeves are movably installed outside the T-shaped columns, and the sleeves are adapted to fit in the transverse grooves.

[0095] When in use, after the nuts in the shift rod assembly bolt 130 are loosened, the first limiting beam 110 and the second limiting beam 120 can be bent in the same direction along the top and bottom of the pad 310. When the angles of the first limiting beam 110 and the second limiting beam 120 are determined, the nuts can be tightened. At this time, the first limiting beam 110 and the second limiting beam 120 can be firmly pressed on the pad 310. At this time, the locked first limiting beam 110 and the second limiting beam 120 can provide a stable support platform for the pad 310, and the stabilized pad 310 can provide vertical support force for the guide rail 350 and the side test mechanism 400, thereby facilitating the booster component 460 to perform multi-point detection of the connection node.

[0096] Embodiment 4:

[0097] Combination Figure 7-Figure 11 As shown, in the above embodiment, the pad 310, the guide rail 350 and the bottom plate 411 are all made of stainless steel pipe material, and the guide rail 350 is used to provide inclination adjustment for the pressure-bearing assembly 410;

[0098] A rubber gasket is disposed at the bottom of one end of the guide rail 350 away from the pad 310 .

[0099] Preferably, after the outer end of the guide rail 350 is attached to the outer wall of the hull, the slide column 420 and the pressure-bearing component 410 extending along the inside of the slide groove 370 can be inclined to adapt to the gradual structural seam, and the structural glue and expansion agent inside the structural seam can be tested by the pressure-boosting rod 467;

[0100] The two return springs 380 disposed in the slide slot 370 can provide a positioning force for rapid calibration for the slide post 420 .

[0101] The working principle and use process of the present invention are as follows: a fiberglass boat is a boat made of fiberglass. An outer layer of paint is pre-coated on the inner wall of a prefabricated mold, and then glass reinforcing fibers are evenly laid inside the dried paint, and the evenly laid glass reinforcing fibers are adhered to the outer layer of paint by using glue. After the glass reinforcing fibers are stacked multiple times, a rough blank of a fiberglass hull is finally formed inside the prefabricated mold. After the rough blank of the fiberglass hull is further polished, the deck, the hull and the bulkhead can be fixed to the hull in steps.

[0102] The assembly of the above components requires the use of self-tapping screws, structural adhesives and expansion agents to fix and seal the gaps of the components. This assembly method is mostly a T-shaped connection node structure. Different from other equipment, the T-shaped connection node on the hull can further increase the pressure that the hull can withstand in different directions;

[0103] In order to detect the compressive strength of the above-mentioned connection nodes and the stability of the connections between the various components of the hull, two reinforcing suction cups 200 are pre-adsorbed on the outer wall of the fiberglass reinforced plastic boat according to the requirements of the ship's side belt detection position, and then the external exhaust equipment and pipelines are connected to the air pipes on the two reinforcing suction cups 200 until the air inside the two reinforcing suction cups 200 is emptied. At this time, the two reinforcing suction cups 200 can provide a sufficiently stable supporting force for the first limiting beam plate 110 and the second limiting beam plate 120. When the adjacent ends of the first limiting beam plate 110 and the second limiting beam plate 120 are bent and adjusted, the nuts in the combined bolts 130 can be tightened. At this time, the first limiting beam plate 110 and the second limiting beam plate 120 after the angle adjustment can be fixed;

[0104] At this time, the pad 310 can be pressed and fixed by the first limiting beam 110 and the second limiting beam 120 after the angle adjustment, and then the second screw rod 330 is controlled to rotate clockwise, and the second screw rod 330 can extend upward along the inside of the second screw sleeve 320, and finally the suspension 340 will push the two clamps 360 and the guide rail 350 to approach the outer wall of the hull and the side of the ship's side, until the outer end of the guide rail 350 is attached to the outer wall of the hull, and the sliding column 420 and the pressure-bearing component 410 movably installed in the clamp 360 will tilt and roll along the outer wall of the hull until the top of the pressure-bearing component 410 is located at the bottom of the ship's side;

[0105] Then, loosen the nut in the combined bolt 130, and then push the adjacent ends of the first limiting beam plate 110 and the second limiting beam plate 120 upward until the top of the pressure-bearing component 410 is inserted into the gap between the ship's side and the hull, and then tighten the combined bolt 130;

[0106] When the above preparations are completed, according to the need for shipboard pressure detection, the hydraulic component 440 is pre-operated. As the hydraulic sub-rod in the hydraulic component 440 extends outward, the hydraulic sub-rod will push the baffle 450 and the push plate 462 to extend upward, and the push plate 462 limited by the side seam base 461 will push the inclined arm 465 and the booster rod 467 to expand. The booster rod 467 is obliquely guided by the gear pin block 413, and the top of the booster rod 467 guided finally can apply outward pressure to the gap between the shipboard and the hull. At this time, the gap between the shipboard, the deck and the hull can be pressurized for detection at the part fixed with self-tapping screws and expansion agents;

[0107] When it is necessary to detect the shaking of the components above the top of the hull, according to the compression and locking of the inner wall of the shell by the teeth at the top of the booster rod 467, it is necessary to use an external traction device to apply pressure to the cable 500. At this time, the side test mechanism 400 as a whole can be tilted along the triangular slide groove 370 in the guide rail 350 to be stressed. At this time, the device can detect whether the top components of the hull are tightly connected. When the deck and other components are installed at the top of the hull and there is shaking, the tilted pressure can cause it to change due to external force;

[0108] At the same time, the device can not only detect the pressure of the connection node between the FRP hull and the side of the ship, but also provide a common effective gap for the addition and supplement of structural adhesive and expansion agent.

[0109] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
