Description

Technical Field

[0001] The present invention relates to the technical field of heat treatment of forgings, and in particular to an electric drive device and method for heat-treating forgings. Background Art

[0002] Wind turbine flange forgings are key metal components used to connect core components such as towers, nacelles, and hubs in wind turbines. They function like "joints," requiring them to withstand significant loads (such as wind pressure, gravity, and vibration) while ensuring structural sealing and long-term stability.

[0003] Wind turbine flange forgings need to be heat treated during the production process, and the heat treatment of wind turbine flange forgings involves the transportation of wind turbine flange forgings. The traditional transportation method is mostly through engineering vehicles for processing-transfer to cooling workshops, and the degree of automation is not high. Therefore, the present invention proposes an electric drive device and method for heat treatment forgings to solve the problems existing in the prior art. Summary of the Invention

[0010] Further improvements are: a through slot is provided on the limit plate, a first infrared temperature measuring instrument is provided on the inner wall of the base support plate at a position flush with the through slot, and multiple groups of second infrared temperature measuring instruments are provided above the conveying roller. The multiple groups of second infrared temperature measuring instruments are symmetrically distributed on both sides of the base support plate and fixedly connected to the inner wall of the base support plate. The first infrared temperature measuring instrument and the second infrared temperature measuring instrument are both connected to the sub-control panel.

[0011] Further improvements are: a first axial flow fan unit is provided at the bottom of the conveying roller, a second axial flow fan unit is provided at the bottom of the top plate, a first U-shaped tube group is provided above the first axial flow fan unit, and a second U-shaped tube group is provided below the second axial flow fan unit, and the first U-shaped tube group and the second U-shaped tube group are respectively provided with an inlet pipe and an outlet pipe at both ends, and three-way valves are installed at the ends of the inlet pipe and the outlet pipe. One ends of the upper and lower groups of three-way valves are connected by a conveying pipe, and the other ends are connected to the pipes for input and output. A water pump is provided on the conveying pipe to ensure water circulation between the first U-shaped tube group and the second U-shaped tube group.

[0012] A further improvement is that the first U-shaped tube group and the second U-shaped tube group have the same structure, both including a mounting frame and a U-shaped loop tube, and multiple groups of the U-shaped loop tubes are sequentially connected and fixed in the mounting frame.

[0013] Further improvements are: the conveying roller is a hollow structure, and connecting pipes are provided at both ends of the conveying roller. The outer sides of the two groups of base support plates are provided with main pipes. One end of the connecting pipe passes through the base support plate and is connected to the main pipe through a rotating joint. The middle end of the main pipe is provided with a pipe for input and output, and a heater is provided inside the conveying roller.

[0014] Further improvements are: the adjustment component includes a bidirectional cylinder, a connecting plate and a connecting rod, the bidirectional cylinder is symmetrically provided with two groups, respectively arranged below the two ends of the first axial fan unit, the output end of the bidirectional cylinder passes through the base support plate and is fixedly connected to the connecting plate, two groups of connecting rods are fixed on the top of the connecting plate, a through hole is provided on the base support plate, one end of the connecting rod passes through the through hole and is fixedly connected to the limit plate.

[0015] A further improvement is that the connecting member includes a first rotating seat, a second rotating seat and an insertion shaft. The first rotating seat is fixed on one side of one end of the electric conveying mechanism, and the second rotating seat is fixed on the other side at the same position as the first rotating seat. The first rotating seat and the second rotating seat are adapted to be connected by an insertion shaft.

[0016] The method of using the above-mentioned electric drive device for heat-treated forgings comprises the following steps:

[0017] S1. Establishment of automatic conveying lines. Lines are planned between workshops, and electric conveying mechanisms are arranged according to the planned lines. Multiple groups of electric conveying mechanisms are articulated through connectors. On the turning lines, the angles between the electric conveying mechanisms are adjusted to achieve turning. At the same time, limit springs are installed between adjacent rotating blocks to limit the position of the wind turbine flange forgings when turning, ensuring smooth turning of the wind turbine flange forgings.

[0018] S2. The operation of the automated conveying line is to drive multiple sets of conveying rollers to rotate, thereby driving the wind turbine flange forgings above the conveying rollers to move. At the partition of the electric conveying mechanism, when it is a straight connection, the wind turbine flange forgings are stably moved to the next set of electric conveying mechanisms. When it is a steering connection, the wind turbine flange forgings first contact with the rotating block, so that the limit spring and the torsion spring work synchronously. At the same time, the conveying rollers synchronously convey continuous forward power, thereby changing the state of the wind turbine flange forgings, so that the wind turbine flange forgings can smoothly enter the next set of electric conveying mechanisms;

[0019] S3. Insulation and cooling treatment of wind turbine flange forgings. During the transportation of wind turbine flange forgings, according to the temperature of the wind turbine flange forgings and the ambient temperature, the first axial flow fan unit and the second axial flow fan unit are started to form air flow channels at the upper and lower ends of the wind turbine flange forgings. When the ambient temperature of the transfer workshop is higher than the preset temperature of 35°C, in order to avoid uneven stress inside the material or degradation of mechanical properties, cold water can be transported into the first U-shaped tube group and the second U-shaped tube group, and the wind turbine flange forgings can be initially cooled by blowing cold air to the wind turbine flange forgings. When the temperature of the wind turbine flange forgings is higher than the set temperature of 900°C, cold water can be transported into the conveying rollers to further increase the cooling effect by contact heat conduction. When the ambient temperature is lower than the preset temperature of 0°C, In order to prevent the flange from overcooling and causing increased brittleness of the material, hot water can be transported into the first U-shaped tube group and the second U-shaped tube group, and the wind turbine flange forging can be initially insulated by blowing hot air into the wind turbine flange forging. After the water flow in the first U-shaped tube group and the second U-shaped tube group has circulated for the first time, hot water will no longer be transported, and the first U-shaped tube group and the second U-shaped tube group will be connected by opening the three-way valve, and the second U-shaped tube group will be heated by the rising hot air flow to achieve thermal circulation and reduce energy consumption. When the temperature drop rate of the wind turbine flange forging is greater than the preset value of 20°C / min, water is transported into the conveying roller and the water flow inside the conveying roller is heated by turning on the heater. The insulation effect is further increased by reducing the temperature difference.

[0020] The beneficial effects of the present invention are as follows: the present invention forms an integrated automatic conveying line by combining multiple groups of electric conveying mechanisms with connecting parts, so that the wind power flange forgings can be automatically conveyed to the cooling workshop during the cooling process after the heat treatment is completed. There is no need for workers to drive engineering vehicles for transportation, which reduces the use of manpower and material resources. At the same time, the use of automated transportation is safer, further increasing the degree of automation of the entire industry. At the same time, the device fully considers the impact of environmental factors on the transportation of wind power flange forgings. By setting the first axial flow fan unit and the second axial flow fan unit in conjunction with the first U-shaped tube group and the second U-shaped tube group, hot air or cold air is evenly conveyed to the wind power flange forgings, and the wind power flange forgings are evenly cooled and insulated, thereby preventing problems with the wind power flange forgings during transportation, greatly increasing the practicality of the device.

[0030] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the examples. The examples are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0031] according to Figures 1-8 As shown, this embodiment provides an electric drive device for heat-treated forgings, including multiple sets of electric conveying mechanisms, with connectors provided between the ends of the multiple sets of electric conveying mechanisms. The multiple sets of connectors cooperate with the multiple sets of electric conveying mechanisms to construct an integrated automatic conveying line. To ensure the smooth operation of the automatic conveying line, the steering angle between the electric conveying mechanisms should not be greater than 30 degrees.

[0032] The electric conveying mechanism includes a base support plate 2, conveying rollers 3 and a top plate 4. The base support plates 2 are symmetrically distributed in two groups, and multiple groups of conveying rollers 3 are provided and are evenly spaced between the two groups of base support plates 2. The top plate 4 is fixed on the top of the two groups of base support plates 2. To further reduce costs, multiple groups of conveying rollers 3 can be driven by the same drive source, and the multiple groups of conveying rollers 3 can be linked together only by chains and sprockets.

[0034] A limit plate 6 is symmetrically provided on the inner side of the base support plate 2. The limit plate 6 is driven by an adjustment assembly. Two sets of rotating blocks 7 are symmetrically provided at both ends of the limit plate 6. Both sets of rotating blocks 7 are rotatably connected to the limit plate 6 through torsion springs. Multiple sets of positioning seats 8 are also fixed on the end faces of the rotating blocks 7.

[0035] A limit spring 9 is provided between two adjacent groups of rotating blocks 7 at the ends of the multiple groups of electric conveying mechanisms, and both ends of the limit spring 9 are respectively mounted on the positioning seats 8 .

[0036] Multiple groups of electric conveying mechanisms are connected through connecting parts to form an integrated automatic conveying line, so that the wind power flange forgings can be automatically conveyed to the cooling workshop during the cooling process after the heat treatment is completed. There is no need for workers to drive engineering vehicles for transportation, which reduces the use of manpower and material resources. At the same time, the use of automated transportation is safer, further increasing the degree of automation of the entire industry. Taking into account the complexity of the lines between the production workshops, the device can perform a certain degree of steering as needed. At the same time, through the design of the rotating block 7 with the torsion spring and the installation of the torsion spring between adjacent rotating blocks 7, it is ensured that when the wind power flange forgings are turned, they can stably enter another group of electric conveying mechanisms from one group of electric conveying mechanisms, ensuring the stability of the transportation of wind power flange forgings and further increasing the usability of the device.

[0037] A through slot 10 is provided on the limiting plate 6, and a first infrared thermometer 11 is provided on the inner wall of the base support plate 2 at a position flush with the through slot 10. A plurality of groups of second infrared thermometers 12 are provided above the conveying roller 3. The plurality of groups of second infrared thermometers 12 are symmetrically distributed on both sides of the base support plate 2 and fixedly connected to the inner wall of the base support plate 2. The first infrared thermometer 11 and the second infrared thermometer 12 are both connected to the sub-control panel 5.

[0038] A first axial flow fan unit 13 is provided at the bottom of the conveying roller 3, and a second axial flow fan unit 14 is provided at the bottom of the top plate 4. A first U-shaped tube group 15 is provided above the first axial flow fan unit 13, and a second U-shaped tube group 16 is provided below the second axial flow fan unit 14. The first U-shaped tube group 15 and the second U-shaped tube group 16 are respectively provided with an inlet pipe 17 and an outlet pipe 18 at both ends. A three-way valve 19 is installed at the end of the inlet pipe 17 and the outlet pipe 18.

The conveying pipe 20 is provided with a water pump 21 to ensure water circulation between the first U-shaped tube group 15 and the second U-shaped tube group 16.

[0039] The first U-shaped tube group 15 and the second U-shaped tube group 16 have the same structure, both including a mounting frame 22 and a U-shaped loop tube 23 . Multiple groups of U-shaped loop tubes 23 are sequentially connected and fixed in the mounting frame 22 .

[0040] The conveying roller 3 has a hollow structure. Connecting pipes 24 are provided at both ends of the conveying roller 3. Main pipes 26 are provided on the outside of the two sets of base support plates 2. One end of the connecting pipe 24 passes through the base support plate 2 and is connected to the main pipe 26 through a rotating joint 25. The middle end of the main pipe 26 is provided with a pipe for input and output. A heater 27 is provided inside the conveying roller 3.

[0041] Taking into account the impact of ambient temperature on the transportation of wind turbine flange forgings, this device sets a first axial flow fan unit 13 and a second axial flow fan unit 14 in conjunction with a first U-shaped tube group 15 and a second U-shaped tube group 16 to insulate the surface of the wind turbine flange forging in a low temperature environment to prevent the brittleness of the surface of the wind turbine flange forging from increasing due to excessive cooling, and to perform a preliminary uniform and slow cooling of the wind turbine flange forging in a high temperature environment, thereby preventing local overheating of the wind turbine flange forging, thereby avoiding the occurrence of uneven stress inside the material, further increasing the scope of use of this device. In order to ensure the safety of the operation of this device, pressure monitoring valves and pressure relief valves are required to be installed on all practical pipes of this device. At the same time, this device adopts the method of controlling multiple groups of sub-control panels 5 by the main control panel 1, which can monitor the temperature in real time, thereby adjusting the temperature of the air blown by the first axial flow fan unit 13 and the second axial flow fan unit 14, further increasing the protection of the wind turbine flange forgings.

[0042] The adjustment component includes a two-way cylinder 28, a connecting plate 29 and a connecting rod 30. The two-way cylinder 28 is symmetrically arranged in two groups, which are respectively arranged below the two ends of the first axial fan unit 13. The output end of the two-way cylinder 28 passes through the base support plate 2 and is fixedly connected to the connecting plate 29. Two groups of connecting rods 30 are fixed to the top of the connecting plate 29. A through hole 31 is provided on the base support plate 2. One end of the connecting rod 30 passes through the through hole 31 and is fixedly connected to the limit plate 6.

[0043] The connecting part includes a first rotating seat 32, a second rotating seat 33 and an insertion shaft 34. The first rotating seat 32 is fixed on one side of one end of the electric conveying mechanism, and the second rotating seat 33 is fixed on the other side at the same position as the first rotating seat 32. The first rotating seat 32 and the second rotating seat 33 are adapted and connected by the insertion shaft 34.

[0044] The method of using the above-mentioned electric drive device for heat-treated forgings comprises the following steps:

[0045] S1. Establishment of automatic conveying lines. Lines are planned between workshops, and electric conveying mechanisms are arranged according to the planned lines. Multiple groups of electric conveying mechanisms are articulated by connectors. On the turning lines, the angles between the electric conveying mechanisms are adjusted to achieve turning. At the same time, limit springs 9 are installed between adjacent rotating blocks 7, so that the wind turbine flange forgings can be limited when turning, ensuring smooth turning of the wind turbine flange forgings.

[0046] S2. The operation of the automated conveying line is achieved by driving multiple sets of conveying rollers 3 to rotate, thereby driving the wind turbine flange forging above the conveying rollers 3 to move. At the partition of the electric conveying mechanism, if it is a straight connection, the wind turbine flange forging can be stably moved to the next set of electric conveying mechanisms. If it is a steering connection, the wind turbine flange forging first contacts the rotating block 7, so that the limit spring 9 and the torsion spring work synchronously, and at the same time, the conveying rollers 3 synchronously convey continuous forward power, thereby changing the state of the wind turbine flange forging, so that the wind turbine flange forging can smoothly enter the next set of electric conveying mechanisms;

[0047] S3. Insulation and cooling treatment of wind turbine flange forgings. During the transportation of wind turbine flange forgings, according to the temperature of the wind turbine flange forgings and the ambient temperature, the first axial flow fan unit 13 and the second axial flow fan unit 14 are started to form air flow channels at the upper and lower ends of the wind turbine flange forgings. Because the temperature of the wind turbine flange forgings themselves is very high, they will continue to conduct heat to the surrounding air due to the temperature difference. When the ambient temperature of the transfer workshop is greater than the preset temperature of 35°C, the temperature difference becomes smaller, which affects the heat dissipation of the wind turbine flange forgings. At this time, in order to avoid uneven internal stress of the material or decreased mechanical properties caused by the slow cooling of the wind turbine flange forgings, cold water can be transported into the first U-shaped tube group 15 and the second U-shaped tube group 16, and the wind turbine flange forgings can be initially cooled by blowing cold air to the wind turbine flange forgings. If the temperature of the wind turbine flange forgings is greater than the set temperature of 900°C, cold water can be transported into the conveying roller 3 to further increase the heat dissipation through contact heat conduction. Cooling effect: When the ambient temperature is lower than the preset temperature of 0°C, the surface temperature of the wind turbine flange forging is very different from the external temperature. In order to prevent the flange from being overcooled, which leads to increased brittleness of the material, hot water can be transported into the first U-shaped tube group 15 and the second U-shaped tube group 16, and the wind turbine flange forging can be initially insulated by blowing hot air into the wind turbine flange forging. After the water flow in the first U-shaped tube group 15 and the second U-shaped tube group 16 has completed the first round of circulation, hot water will no longer be transported, and the three-way valve 19 will be opened to connect the first U-shaped tube group 15 and the second U-shaped tube group 16, and the second U-shaped tube group 16 will be heated by the rising hot air flow to realize thermal circulation and reduce energy consumption. If the temperature drop rate of the wind turbine flange forging is greater than the preset value of 20°C / min, water will be transported into the conveying roller 3 at this time, and the water flow inside the conveying roller 3 will be heated by turning on the heater 27. By reducing the temperature difference, the insulation effect is further increased.

[0048] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and descriptions are merely illustrative of the principles of the present invention.

By opening the three-way valve (19), the first U-shaped tube group (15) and the second U-shaped tube group (16) are connected. The second U-shaped tube group (16) is heated by the rising hot air flow to achieve thermal circulation and reduce energy consumption. When the temperature drop rate of the wind turbine flange forging is greater than the preset value of 20°C / min, water is transported into the conveying roller (3) and the water flow inside the conveying roller (3) is heated by turning on the heater (27). By reducing the temperature difference, the insulation effect is further increased.
