Description

Technical Field

[0001] The 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 offshore engineering industry, the market has put forward higher requirements for mooring chains. There are two major trends, one is high strength and the other is large specifications. The former is mainly to ensure strength by improving the strength of the material, while the latter is to achieve strength requirements by increasing the specifications. As one of the key processes in the manufacture of mooring chains, heat treatment has a vital impact on the performance of the final product. The production process of mooring chains generally includes cutting, ring weaving, welding, burr removal, heat treatment, tensile testing, surface shot blasting and varnishing. The heat treatment of mooring chains generally includes quenching and tempering. The mooring chain is first heated to a high temperature, then sent to a quenching furnace, water-cooled, and then transported to a tempering furnace for tempering and water cooling.

[0003] In the existing chain heat treatment device, the quenching furnace and the tempering furnace are separate and need to be operated in the middle, so that continuous heat treatment cannot be provided, which reduces production efficiency; and when the heated chain is placed in the cooling pool for cooling, there will be a certain amount of oxide skin or debris on its surface, which will fall into the water during rapid cooling, and the debris will stick to the chain that is subsequently heat treated, thus causing inaccurate results of crack detection after heat treatment and affecting the processing quality of the chain.

[0004] The Chinese invention patent with the patent number CN117845037A discloses a chain heat treatment device with crack detection function, which relates to the field of anchor chain heat treatment technology, including a tempering component, a detection component, a transfer component, and a base plate. The base plate is fastened to the ground, and the tempering component, the detection component, and the transfer component are arranged above the base plate. The tempering component, the detection component, the transfer component, and the base plate are fastened. The transfer component includes a loading conveyor belt, a unloading conveyor belt, and a transition unit. The transition unit is provided with multiple groups, and the transition units are respectively arranged on both sides of the tempering component and the detection component. The tempering component and the detection component are arranged adjacently. The loading conveyor belt is arranged on the side of the tempering component away from the detection component, and the unloading conveyor belt is arranged on the side of the detection component away from the tempering component. The invention realizes continuous heat treatment of the entire anchor chain through the coordinated cooperation of the tempering component and the detection component, and greatly improves the heat treatment efficiency. However, while providing a mechanism for detecting cracks, the invention does not propose a solution for removing the oxide cortex or debris generated during the heat treatment process, which leads to inaccurate crack detection results after heat treatment.

[0026] like Figure 1 and Figure 7As shown, the circulating water cooling mechanism 6 includes a water cooling box 61 arranged at one side of the cooling pool 2, the water cooling box 61 is connected to the cooling pool 2 through a water delivery pipe 63, a water delivery pump 64 is installed on the water delivery 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, a box cover is hingedly installed on the top of the water filter box 621, and the water filter box 621 is located above the filter screen 622. 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 provided on the water pump 623; the direction of the circulating water flow in the cooling pool 2 is opposite to the moving direction of the mooring chain; a mounting plate 12 is connected to the side of the cooling pool 2 close to the first chain conveying assembly 5, a third rotating wheel 13 is rotatably installed on the mounting plate 12, and a fourth rotating wheel 14, a fifth rotating wheel 15 and a sixth rotating wheel 16 for guiding the movement of the mooring chain are rotatably installed in the cooling pool 2; 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 guided by the fourth rotor 14 and the fifth rotor 15, then enters the tempering assembly 32 upward, and comes out of the second heating pipe 324 and enters the cooling pool 2 downward.

The cross channel limits the chain, and then the chain moves forward into the first detection cylinder 93. Since the entire mooring chain is composed of a combination of horizontal chains and vertical chains alternately, the second cross channel 931 provided in the first detection cylinder 93 is intended to detect cracks in the horizontal chains. Fig.10As shown in the cross-sectional view BB in FIG. 1 , 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.
