Description

Technical Field

[0001] The present invention relates to the field of welding technology, and particularly to a welding device and method suitable for processing a ship stern shaft sealing device. Background Art

[0002] The task of the stern tube is to support the stern shaft or propeller shaft and enable the supported stern shaft or propeller shaft to reliably pass out of the ship without allowing a large amount of water outside the ship to leak into the ship, and at the same time, not allowing the lubricating oil to leak out. The stern tube device generally consists of parts such as a stern tube, a stern bearing, a sealing device, and a lubrication and cooling system.

[0003] During the process of processing a ship stern shaft sealing device, a welding device is often required to perform welding treatment on the connection part. Since the thickness of the ship stern shaft sealing device is relatively high, preheating treatment is required. However, the preheating is generally carried out at a specified temperature, and the temperature distribution uniformity of sudden high-temperature preheating is poor. Moreover, due to the drastic temperature change, relatively large thermal stress may be generated, increasing the risk of welding cracks, and the energy consumption is relatively large. And when the weld seam is relatively wide, the welding head usually cannot reciprocate during welding, resulting in a temperature difference between the inner and outer sides of the weld seam, affecting the welding effect of the weld seam. And during the use of the welding equipment, welding generates high-temperature waste gas, which not only easily scalds the nearby personnel, but also the pollutants in the high-temperature waste gas will pollute the environment, and long-term inhalation will endanger personal safety.

[0004] In view of the above problems, the present invention document proposes a welding device and method suitable for processing a ship stern shaft sealing device. Summary of the Invention

[0018] A use method of a welding device suitable for processing a ship stern shaft sealing device includes the following steps:

[0019] S1. When welding the ship stern shaft, the welding head is controlled to move forward through the welding equipment, so as to realize the welding operation of the ship stern shaft. High-temperature heat is generated during the welding process. The double-shaft motor drives the second rotating shaft to rotate. The second rotating shaft below drives the second bevel gear to transmit with the third bevel gear. The third bevel gear drives the first rotating shaft to rotate. The first rotating shaft drives the first fan blade to rotate, so that the first fan blade can transport heat into the heat conduction cavity through negative pressure. After the heat passes through the filter layer for filtration and purification treatment, it flows to the other end of the heat conduction cavity. Part of the heat is discharged through the heat conduction cavity, and part of the heat is guided out through the side cavity. The heat is cooled by the heat dissipation fins. In this way, the heat discharged through the side cavity is preheated for the first time, and the heat discharged through the heat conduction cavity is preheated for the second time;

[0020] S2. The second rotating shaft above also drives the second fan blade to rotate. The second fan blade exhausts air through the ventilation duct, so that the air flow speeds up the air flow speed around the heat dissipation fins, improves the heat conduction efficiency of the heat dissipation fins, cools the heat, and meets the requirement of realizing hierarchical preheating by heat utilization;

[0021] S3. Drive the first bevel gear and the fourth bevel gear to transmit through the second rotating shaft above. The fourth bevel gear drives the third rotating shaft to drive the adjusting cylinder to rotate, so that the adjusting cylinder drives the movable strip to move up and down through the adjusting column and the rotating roller, so that the sliding rod drives the roller to move up and down, so that the roller swings the upper cavity relying on the arc-shaped opening, so that the heat conduction cavity swings, so that the welding head swings to achieve uniform welding operation, and through the swing of the heat conduction cavity and the side cavity, the uniform preheating of the ship's tail shaft can be maintained in this way.

[0022] Compared with the prior art, the present invention provides a welding device and method applicable to the processing of ship tail shaft sealing devices, and has the following beneficial effects:

[0023] 1. For the welding device and method applicable to the processing of ship tail shaft sealing devices, the second rotating shaft is driven to rotate by the double-shaft motor, so that the first bevel gear and the fourth bevel gear can drive the movable strip to reciprocate through the adjusting column, so that the sliding rod drives the rotating roller to move. The rotating roller can drive the upper cavity and the heat conduction cavity to swing relying on the arc-shaped opening. The swing of the heat conduction cavity can drive the welding head to swing and weld, so as to increase the welding area, improve the firmness of the welding, and maintain the uniformity of the welding. Secondly, through the reciprocating swing of the heat conduction cavity, the preheating area can also be increased, and the preheating uniformity of the ship's tail shaft can be improved.

[0024] 2. For the welding device and method applicable to the processing of ship tail shaft sealing devices, the second rotating shaft below is driven to rotate by the double-shaft motor, and the second bevel gear and the third bevel gear are driven to transmit by the second rotating shaft, so that the first rotating shaft drives the first fan blade to rotate. Then the high-temperature heat generated during the welding process of the welding head can be recovered into the heat conduction cavity and conducted to the other end of the heat conduction cavity. At this time, part of the heat is discharged through the guidance of the side cavity, and the heat is conducted outward through the heat dissipation fins on the side cavity to reduce the temperature. In addition, the second rotating shaft above also drives the second fan blade to exhaust through the ventilation duct, so that the air flow speed around the heat dissipation fins is accelerated, the heat dissipation effect is improved, the heat discharged from the side cavity is reduced, and the ship's tail shaft is preheated for the first time, and then preheated for the second time through the heat discharged from the heat conduction cavity, so as to achieve the purpose of gradient grading preheating and improve the welding quality.

[0025] 3. The welding device and method applicable to the processing of ship stern shaft sealing devices drive the second rotating shaft to rotate through a double-shaft motor, enabling the transmission between the second bevel gear and the third bevel gear to drive the first rotating shaft and the first fan blade to rotate. The fan blade can introduce the waste gas generated during welding into the heat conduction cavity through negative pressure, avoiding the outward diffusion of the waste gas, thus preventing the risk of high-temperature waste gas injuring people. Moreover, the waste gas can be subjected to multi-stage filtration treatment through the filter layer, avoiding environmental pollution and improving the working environment. The filtered high-temperature waste gas can preheat the ship stern shaft, thereby realizing the utilization of waste gas. And it is discharged from the other end of the heat conduction cavity, enabling continuous preheating and welding operations. In addition, the second rotating shaft above drives the transmission between the first bevel gear and the fourth bevel gear, enabling the third rotating shaft to drive the movable strip to reciprocate through the adjusting column. In this way, with the cooperation of the rotating roller and the arc-shaped opening, the heat conduction cavity swings, thereby increasing the intake area, effectively avoiding the leakage of waste gas, and greatly improving the preheating and welding effects.
