Description

Technical Field

[0001] The present invention relates to the technical field of heat treatment of mooring chains, in particular to heat treatment equipment for mooring chains. Background Art

[0002] With the development of ocean development and the offshore engineering industry, the market has placed higher demands on mooring chains. Two major trends are currently driving demand for higher strength and larger specifications. The former primarily achieves strength by increasing material strength, while the latter achieves strength requirements by increasing specifications. Heat treatment, a key process in mooring chain manufacturing, has a crucial impact on the performance of the final product. The production process for mooring chains generally includes cutting, braiding, welding, deburring, heat treatment, tensile testing, surface shot blasting, and varnishing. Heat treatment of mooring chains typically involves quenching and tempering. The mooring chain is first heated to a high temperature, then transferred to a quenching furnace for water cooling. After completion, it is transferred to a tempering furnace for tempering and water cooling.

[0003] In existing chain heat treatment devices, the quenching furnace and tempering furnace are separate and need to be operated in between, which makes it impossible to provide continuous heat treatment and reduces production efficiency. In addition, when the heated chain is placed in the cooling pool for cooling, a certain amount of oxide scale or debris on its surface will fall into the water during rapid cooling, and the debris will stick to the chain during subsequent heat treatment. This will cause inaccurate crack detection results after heat treatment and affect the processing quality of the chain.

[0004] Chinese invention patent number CN117845037A discloses a chain heat treatment device with crack detection capabilities, relating to the field of anchor chain heat treatment technology. The device comprises a tempering assembly, a detection assembly, a transfer assembly, and a base plate, which is securely connected to the ground. The tempering assembly, detection assembly, and transfer assembly are positioned above the base plate, securely connected to the base plate, and the transfer assembly includes a loading conveyor belt, a unloading conveyor belt, and a transition unit. Multiple transition units are provided, one on each side of the tempering assembly and the other adjacent to the other. The loading conveyor belt is positioned on the side of the tempering assembly away from the detection assembly, and the other on the side of the detection assembly away from the tempering assembly. This invention, through the coordinated cooperation of the tempering and detection assemblies, enables continuous heat treatment of the entire anchor chain, significantly improving heat treatment efficiency. However, while this invention provides a mechanism for crack detection, it does not address the removal of scale or debris generated during the heat treatment process, resulting in inaccurate crack detection results after heat treatment.

A first chain conveying assembly 5 is provided on one side of the frame 1 for conveying the mooring chain to the tempering mechanism 3, a circulating water cooling mechanism 6 is connected to one side of the cooling pool 2, and the circulating water cooling mechanism 6 includes a water cooling box 61 and a debris filtering device 62. A vibrating frame 7 is provided on the other side of the frame 1 for removing water and slag from the mooring chain, and a second chain conveying assembly 8 is installed on the frame 1 for conveying the mooring chain to the vibrating frame 7. A crack detection mechanism 9 is provided on one side of the vibrating frame 7, and a third chain conveying assembly 10 is provided on one side of the crack detection mechanism 9.

[0038] like Figure 1-2 As shown, the first chain conveyor assembly 5 includes a mounting frame 51, a first sprocket wheel 52 is rotatably mounted on the top of the mounting frame 51, a first drive motor 53 is mounted on the side of the mounting frame 51, and the output end of the first drive motor 53 is fixedly connected to the rotating rod of the first sprocket wheel 52; the first chain conveyor assembly 5 is the same as the third chain conveyor assembly 10; the second chain conveyor assembly 8 includes a second sprocket wheel 81 rotatably mounted on the support leg of the frame 1, and the rotating rod of the second sprocket wheel 81 is fixedly connected to the output end of the second drive motor 82 mounted on the support leg of the frame 1; when in use, the first chain conveyor assembly 5, the second chain conveyor assembly 8 and the third chain conveyor assembly 10 respectively use the drive motor to drive the sprocket wheels to rotate to convey the chains, so that the mooring chains can be automatically conveyed during heat treatment, reducing manual intervention and improving production efficiency;

[0039] like Figure 3-5As shown, the quenching assembly 31 includes a first installation box 311 arranged on the top surface of the frame 1, and a first rotating wheel 312 is rotatably installed in the first installation box 311. The first chain inlet pipe 313 and the first heating pipe 314 are connected to the two sides of the bottom of the first installation box 311 respectively; the first heating pipe 314 is divided into a vertical part, an arc part and a horizontal part. The vertical part of the first heating pipe 314 is provided with a heating furnace 3141, the arc part connected to the vertical part is provided with a heat preservation furnace 3142, and the horizontal part is a chain outlet pipe 3143; the tempering assembly 32 is arranged on one side of the quenching assembly 31, and the tempering assembly 32 includes a A second installation box 321 is provided on the top surface of the frame 1. A second rotating wheel 322 is rotatably installed in the second installation box 321. A second chain feed pipe 323 and a second heating pipe 324 are connected and installed on both sides of the bottom of the second installation box 321. The second heating pipe 324 is identical to the first heating pipe 314. Positioning pulleys are provided on the inner walls of the first chain feed pipe 313, the first heating pipe 314, the second chain feed pipe 323, and the second heating pipe 324. The positioning pulleys are provided in pairs, and the mooring chain passes between the positioning pulleys, thereby ensuring the stable operation of the mooring chain during the heat treatment process and preventing chain deviation and wear.

[0040] During use, the mooring chain is first quenched: the mooring chain enters the first installation box 311 from the first chain inlet pipe 313, and then enters the first heating pipe 314 through the first rotor 312, where the heating furnace 3141 heats the chain. As the mooring chain moves, the heated chain enters the insulation furnace 3142 for temperature equalization, and then continues to move downward through the horizontal chain outlet pipe 3143 into the cooling pool 2 for cooling. The horizontally arranged chain outlet pipe 3143 prevents the steam generated by the heated chain when entering the cooling pool for cooling from directly rushing into the heating furnace and affecting the heating system; then the mooring chain is tempered: after completing cooling in the cooling pool 2, the mooring chain enters the second installation box 321 from the second chain inlet pipe 323, and then enters the second heating pipe 324 through the second rotor 322. Similar to the first heating pipe 314, the chain is heated and insulated, and then enters the cooling pool 2 again for cooling.

[0041] like Figure 1 、 Figure 5 and Figure 6As shown, the blowing assembly 4 includes an air pump 41 installed on the top surface of the frame 1 and multiple groups of blowing rings 42 installed on the second chain inlet pipe 323. The blowing ring 42 is connected to the air pump 41 through a pipeline; the blowing ring 42 includes a blowing block 421 installed around the side wall of the second chain inlet pipe 323, each blowing block 421 is tilted downward, and the blowing port of the blowing block 421 blows air obliquely downward into the second chain inlet pipe 323. Two adjacent blowing blocks 421 are connected by an air pipe 422. After the mooring chain is quenched, when the chain enters the second chain inlet pipe 323, in order to avoid the subsequent When the chain is tempered, the surface of the chain may be affected by the adhesion of oxide cortex or debris, which affects the chain quality. Therefore, this blowing assembly 4 is installed on the second chain inlet pipe 323. When in use, the air pump 41 is started to supply air to the multiple sets of blowing rings 42 through the pipeline, thereby causing the blowing block 421 to blow air, and the blowing port of the blowing block 421 is aligned with the inside of the pipe and blows air diagonally downward. Therefore, as the mooring chain rises and moves, the blowing blocks in the multiple sets of blowing rings 42 can comprehensively blow air to remove water and debris from the mooring chain, thereby ensuring the smooth progress of subsequent processes and avoiding the influence of impurities on product quality.

[0042] like Figure 1 and Figure 7 As shown, the circulating water cooling mechanism 6 includes a water cooling box 61 arranged on one side of the cooling pool 2, the water cooling box 61 is connected to the cooling pool 2 through a water pipe 63, a water pump 64 is installed on the water pipe 63, and a debris filtering device 62 is connected to one side of the water cooling box 61 through a pipeline; the debris filtering device 62 includes a water filter box 621, a filter screen 622 is hung in the water filter box 621, and a box cover is installed on the top of the water filter box 621 through a hinge. 1 is provided with a water pump 623, the other end of which is connected to the cooling pool 2, and a water pump 624 is installed on the water pump 623; the direction of the circulating water in the cooling pool 2 is opposite to the direction of movement of the mooring chain; a mounting plate 12 is connected to the side of the cooling pool 2 near the first chain conveyor assembly 5, and a third runner 13 is rotatably mounted on the mounting plate 12. A fourth runner 14, a fifth runner 15, and a sixth runner 16 for guiding the movement of the mooring chain are rotatably mounted in the cooling pool 2;

[0043] When the mooring chain comes out of the first heating pipe 314 and enters the cooling pool 2 for cooling, the chain is immersed in the pool water and is guided by the fourth runner 14 and the fifth runner 15, then enters the tempering assembly 32 upward, and comes out of the second heating pipe 324 and enters the cooling pool 2 downward. Then, the chain is guided by the sixth runner 16 and enters the next process through the second chain conveying assembly 8. When the mooring chain is cooled in the cooling pool 2, the circulating water cooling mechanism 6 works to circulate the cooling water in the cooling pool 2. First, the water pump 624 is started to pump the cooling water in the cooling pool 2 into the water filter box 621 through the water pumping pipe 623. Then, the filter screen 622 filters the debris in the pumped cooling water. The filtered cooling water It flows from the filtered water box 621 to the water cooling box 61, which cools the cooling water. The water cooling box 61 can be cooled by a water cooler or air cooling, both of which are existing technologies. Then the water pump 64 uses the water pipe 63 to transport the cooled coolant back to the cooling pool 2 to form a circulating cooling. When the cooling water is circulated, the direction of the water flow in the cooling pool 2 is opposite to the direction of movement of the chain at the bottom of the water. Therefore, on the one hand, the flow impact of the water flow can assist in removing debris from the surface of the chain, and on the other hand, the water flow can accelerate the cooling of the chain. In addition, as the water volume in the cooling pool 2 decreases and the water level drops, the water volume can be replenished by adding water to the filtered water box 621 or to the water cooling box 61.

[0044] like Figure 1 and Figure 8 As shown, the vibration frame 7 includes a fixing plate 71 and a support frame 72 installed on the fixing plate 71. Both sides of the top of the support frame 72 are provided with raised clamping parts 73. A vibration unit is provided inside the clamping part 73, and an elastic pad is provided on the surface of the clamping part 73; a slope surface 74 inclined to both sides is provided between the two clamping parts 73, and an elastic pad is provided on the slope surface 74. A slag storage box is provided between the supporting legs of the support frame 72; after the mooring chain is quenched and tempered, when the chain passes through the second chain conveying assembly 8 and the vibration frame 7, the clamping parts 73 clamp the chain from both sides, and the vibration unit inside the clamping part 73 starts to move the chain. The vibration unit is vibrated to remove water and slag from the tempered chain, thereby ensuring the processing quality of the mooring chain and pre-cleaning the crack detection of the mooring chain after heat treatment in the next step, thereby avoiding the large error caused by the slag on the surface of the mooring chain on the detection; when the vibration unit vibrates, it may drive the support frame 72 to vibrate, so the support frame 72 is fixedly installed to the fixed plate 71, and the fixed plate 71 is fixedly installed to the ground, and the slag shaken off by the vibration unit will fall into the slag storage box along the slope surface 74; wherein, the vibration unit belongs to the conventional technical means in this field, and the specific structure is not described.

[0045] like Figure 1 、 Figure 9 and Figure 10As shown, the crack detection mechanism 9 includes a mounting platform 91, and a limiting cylinder 92 is provided on the top of the mounting platform 91 near the vibration frame 7. A first cross channel 921 is provided in the limiting cylinder 92, and a guide slope is provided on the side of the first cross channel 921; a first detection cylinder 93 for detecting the horizontal chain is connected to one side of the limiting cylinder 92, a second cross channel 931 connected to the first cross channel 921 is provided in the first detection cylinder 93, the width of the horizontal channel in the second cross channel 931 is greater than the horizontal channel in the first cross channel 921, and detectors 11 are installed on both side walls of the horizontal channel of the second cross channel 931; a second detection cylinder 94 for detecting the vertical chain is connected to one side of the first detection cylinder 93, a third cross channel 941 connected to the first cross channel 921 is provided in the second detection cylinder 94, the width of the vertical channel in the third cross channel 941 is greater than the vertical channel in the first cross channel 921, and detectors 11 are installed on both side walls of the vertical channel of the third cross channel 941;

[0046] After passing through the vibration frame 7, the mooring chain enters the first cross channel 921 of the limiting cylinder 92 through the guide slope provided on the limiting cylinder 92. The cross channel limits the chain, and then the chain moves forward and enters the first detection cylinder 93. Since the entire mooring chain is composed of alternating horizontal chains and vertical chains, the second cross channel 931 provided in the first detection cylinder 93 is used to detect cracks in the horizontal chains. Figure 10 As shown in the cross-sectional view BB in FIG, the horizontal channel in the second cross channel 931 is relatively wide, and detectors 11 are installed on both side walls of the horizontal channel to detect the cross chain; then the chain enters the third cross channel 941 of the second detection cylinder 94, as shown in FIG. Figure 10 As shown in the cross-sectional view CC in , the vertical channel of the third cross channel 941 is wider, and detectors 11 are installed on both sides of the vertical channel to detect cracks in the vertical chain. The two-stage separate detection can, on the one hand, better limit the chain, and on the other hand, conduct a more comprehensive and accurate detection of the mooring chain, so as to reduce the interference and error generated when the horizontal chain and the vertical chain are detected at the same time, thereby discovering the defects of the chain after heat treatment and improving the heat treatment process in time.

[0047] The working principle of the present invention is as follows: the first chain conveying assembly 5 conveys the mooring chain, and the chain enters the quenching assembly 31 after passing through the third rotor 13, and is heated in the first heating pipe 314. The chain then enters the cooling pool 2 for quenching and cooling. After being guided by the fourth rotor 14 and the fifth rotor 15, the chain enters the tempering assembly 32 upward. When the chain enters the second chain inlet pipe 323, the blowing ring 42 in the blowing assembly 4 blows air to remove water and slag from the chain. Then the second heating pipe 324 tempers the chain, and then the chain continues to enter the cooling pool 2 for tempering and cooling. After being guided by the sixth rotor 16, the chain is driven to move by the second chain conveying assembly 8. When the chain is cooled in the cooling pool 2, the water pump 624 pumps the cooling water in the pool into the filter water box 621. The filter water box 621 filters the cooling water, and then the cooling water is transported to the water cooling box 61 for cooling, and then the cooling water is transported back to the cooling pool 2 by the water pump 64 to form circulating water cooling; the chain is transported to the vibration frame 7 under the drive of the second chain conveying component 8, wherein the clamping parts 73 on both sides of the top of the support frame 72 clamp the chain, and vibrate through the vibration unit arranged in the clamping part 73 to shake off the debris and water stuck on the chain, and then the chain enters the limiting cylinder 92, and then enters the second cross channel 931 in the first detection cylinder 93, and the detector 11 is used to detect cracks on the horizontal chain after heat treatment. As the chain moves, it enters the third cross channel 941 in the second detection cylinder 94, and the detector 11 is used to detect cracks on the vertical chain. The detector 11 includes a detection camera and a directional light source, which can record data on the crack position; finally, the mooring chain is transported out under the drive of the third chain conveying component 10 to complete the heat treatment process.
