Description

Technical Field

[0001] The utility model relates to the technical field of detection tooling, in particular to a resin bonding firmness detection tooling used for LNG ships. Background Art

[0002] LNG ship, or liquefied natural gas ship, is a special ship for transporting liquefied gas at a low temperature of -163 degrees Celsius. This type of ship is considered a "three high" product of high technology, high difficulty and high added value, and is often called a "super freezer at sea". LNG ships, large luxury cruise ships and aircraft carriers are known as the three pearls in the crown of the shipbuilding industry. Currently, only a few countries have the ability to build such ships. LNG ships have the advantages of high safety, high efficiency, high environmental protection and strong wind and wave resistance. In terms of types, LNG ships are mainly divided into membrane type and independent liquid tank type (or self-supporting type) according to different cargo tank systems, and independent liquid tank types include spherical tank type and diamond type. In addition, according to different cargo systems, LNG ships can also be divided into traditional LNG ships, LNG ships with reliquefaction devices, and LNG ships with regasification devices.

[0003] As the main means of transporting liquefied natural gas, the structural safety of LNG ships is of vital importance. Resin adhesives are widely used in the construction and maintenance of LNG ships, especially in the installation of insulation boards. Therefore, the bonding strength of resin adhesives directly affects the structural strength and sealing performance of ships. At present, the means of testing the bonding strength of resins is to use a tool to fix the resin coating position, and after the resin reaches the specified time, use a tensile test device to test the resin bonding strength and the bonding strength of the resin-bonded insulation board. This method is cumbersome to operate, and the detection efficiency is relatively low, and it is difficult to meet the needs of fast and accurate detection. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example:

[0029] like Figures 1 to 6 As shown, a resin bonding firmness detection tool for LNG ships includes a body 1, a detection platform 3 is fixed on the upper side of the body 1 by screws, a gantry bracket 4 is arranged on the upper side of the detection platform 3, a pull rod 8 is vertically penetrated through the top of the gantry bracket 4, a tension sensor 9 is installed at the lower end of the pull rod 8, an upper bonding component 7 is arranged on the lower side of the tension sensor 9, a lower bonding component 6 is fixed on the detection platform 3 on the lower side of the upper bonding component 7, and a lifting mechanism 5 is fixed on the left side of the upper end surface of the gantry bracket 4. This design solves the problems that the existing resin bonding firmness detection operation is cumbersome, the detection efficiency is relatively low, and it is difficult to meet the needs of fast and accurate detection.

[0030] A display screen 2 for displaying the pulling force value is installed on the front side of the body 1, which is used to display the pulling force value in real time for the convenience of observation by the operator. Rubber foot pads 11 are installed near the four corners of the bottom of the body 1 to increase the friction between the tooling and the ground and improve stability.

[0031] A sliding seat 81 is provided at the connection between the pull rod 8 and the gantry bracket 4. The sliding seat 81 is embedded in the gantry bracket 4. The pull rod 8 passes through the sliding seat 81 and is slidably connected with it. The sliding seat 81 supports and guides the pull rod 8, which can reduce the friction of the pull rod 8 during the up and down sliding process, ensure the smoothness of the movement, and at the same time ensure a close fit between it and the gantry bracket 4 to prevent the pull rod 8 from shaking or deflecting during the sliding process.

[0032] The lifting mechanism 5 includes a servo motor 51, a hollow column 52 and a threaded sleeve 53. The hollow column 52 is arranged on the upper side of the gantry bracket 4, and its bottom is fixedly connected to the gantry bracket 4 by bolts. A screw rod 54 is vertically arranged inside the gantry bracket 4. The upper end of the hollow column 52 is equipped with a servo motor 51. The output end of the servo motor 51 is fixedly connected to the screw rod 54 through a coupling. The screw rod 54 is equipped with a threaded sleeve 53 through threaded engagement. The threaded sleeve 53 is fixedly connected to a support arm 56. A slide groove 55 is opened on the right side of the hollow column 52. The support arm 56 extends from the slide groove 55 and is fixedly connected to the pull rod 8. The lifting mechanism 5 is used to drive the pull rod 8 to perform precise lifting and lowering movements to detect the resin bonding firmness. When the servo motor 51 is started, its power will be smoothly transmitted to the screw 54 through the coupling, thereby driving the screw 54 to rotate. When the screw 54 rotates under the drive of the servo motor 51, the threaded sleeve 53 will move up and down along the axial direction of the screw 54, driving the support arm 56 and the pull rod 8 to move up and down together, thereby realizing precise control of the lifting and lowering movement of the pull rod 8.

[0033] The upper bonding assembly 7 is composed of a limiting card plate 71, an upper bonding platform 72, a bottom plate 73 and a slot 74. The bottom plate 73 is arranged at the lower side of the tension sensor 9 and is fixedly connected thereto. The upper bonding platform 72 is arranged at the lower side of the bottom plate 73. The upper bonding platform 72 is provided with a T-shaped limiting card plate 71 on the top surface of the upper bonding platform 72 in an integrated manner. The bottom plate 73 is provided with a slot 74 of a T-shaped structure for accommodating the limiting card plate 71. The limiting card plate 71 is inserted into the slot 74.

[0034] An arc-shaped side plate 75 is fixedly provided at the rear edge of the annular surface of the bottom plate 73. The side plate 75 is designed to limit and block the upper bonding platform 72 from the edge to prevent the upper bonding platform 72 from loosening and falling off from the slot 74, thereby ensuring the connection stability between the upper bonding platform 72 and the bottom plate 73.

[0035] The lower bonding component 6 is composed of a lower bonding platform 61, a limiting block 62, a fixing seat 63 and a limiting slot 64. The fixing seat 63 is fixedly installed on the detection platform 3 by multiple sets of bolts. The lower bonding platform 61 is placed inside the fixing seat 63. The height of the lower bonding platform 61 is greater than the height of the fixing seat 63. Two sets of limiting blocks 62 are symmetrically arranged on the annular surface of the lower bonding platform 61 near the bottom edge. Two sets of limiting slots 64 of L-shaped structures for accommodating the limiting blocks 62 are symmetrically opened inside the fixing seat 63.

At this time, the lower bonding platform 61 is firmly fixed in the fixing seat 63. The limit block 62 and the limit slots 64 can ensure the accurate position of the lower bonding platform 61 in the fixing seat 63, prevent it from moving during the detection process, and simplify the installation and removal process of the lower bonding platform 61. When the lower bonding platform 61 needs to be replaced, it only needs to remove the limit block 62 from the limit slots 64, and the lower bonding platform 61 can be easily removed from the fixing seat 63, which is convenient for cleaning the lower bonding platform 61.

[0036] The working principle of the resin bonding firmness detection tool for LNG ships is as follows: first, the operator applies the resin to be tested on the upper surface of the lower bonding platform 61, and then adjusts the height of the pull rod 8 through the lifting mechanism 5, so that the lower surface of the upper bonding platform 72 contacts the resin, so that the resin forms a bonding surface between the upper bonding platform 72 and the lower bonding platform 61. After the resin reaches the specified time. Start the servo motor 51, and smoothly transmit the power to the screw 54 through the coupling to drive the screw 54 to rotate. The threaded sleeve 53 then moves up and down along the axis of the screw 54, and drives the pull rod 8 to perform precise lifting and lowering movements through the support arm 56, and then applies tension to the bonding surface through the pull rod 8, and controls the pull rod 8 to continue to move upward until the resin bonding surface breaks and separates. The tension sensor 9 measures and records the tension value of the bonding surface in real time during the stretching process, and displays these data on the display screen 2 on the front side of the body 1, which is convenient for the operator to observe and analyze in real time. By comparing the tension value and the area of ​​the resin bonding surface under different conditions, the operator can evaluate the bonding firmness of the resin adhesive and judge whether it meets the use requirements. After the inspection is completed, the operator disassembles the upper bonding table 72 and the lower bonding table 61, cleans the resin on the surface, and prepares for the next inspection.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
