Description

Technical Field

[0001] The present invention relates to the field of welding, and more particularly to a wind power generation support tower steel welding device. Background Art

[0002] The wind turbine tower is the tower of wind power generation. It mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the set. The wind tower is generally cut by a CNC cutting machine. The thick plate needs to be beveled. After the plate is rolled and formed by the rolling machine, spot welding, positioning, and confirmation are carried out, and the inner and outer longitudinal seams are welded. After the roundness is checked, if there is a problem, a second rounding is carried out. After the single-section cylinder is welded, the hydraulic group is used to assemble the roller frame for spot welding, and the inner and outer circumferential seams are welded. After the straightness and other tolerances are checked, the flange is welded, and non-destructive testing and flatness inspection of the weld are carried out. After sandblasting and painting, the internal parts are installed and the finished product is inspected, and finally transported to the installation site.

[0003] In the prior art, when welding a tower, a roller support frame is usually used to fix and support the tower, and the tower is driven to rotate to achieve the purpose of welding. However, the tower is very thick and heavy, requiring a large driving force, and it is difficult to rotate it smoothly. Moreover, after welding, the weld seam cannot be automatically and automatically dissipated according to the temperature of the weld seam. In addition, if the welding head is offset during welding, it will affect the welding quality of the tower.

[0004] Therefore, a wind power generation support tower steel welding device is proposed to improve the above problems. Summary of the Invention

[0005] In response to the problems existing in the prior art, the purpose of the present invention is to provide a wind power generation support tower steel welding device, which can stably support the tower without the need for tower rotation. The welding head moves automatically to achieve the welding purpose, and can always keep the welding head in the position of the vertical seam without deviation, thereby ensuring the welding quality. It can also automatically blow air to dissipate heat according to the real-time temperature at the weld.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] The cam is provided with a plurality of support rods, the support rods being fixed with a plurality of support rods and the support rods being fixed with a plurality of support rods at the bottom of the frame. The support rods are provided with a plurality of support rods at the bottom of the frame. The support rods are fixed with a plurality of support rods at the top of the frame. The support rods are fixed with a plurality of support rods at the bottom of the frame. The support rods are fixed with a plurality of support rods at the top of the frame. The support rods are fixed with a plurality of support rods at the bottom of the frame.

[0008] The tower is placed on the shaping plate by means of a lifting mechanism, thereby limiting and fixing the tower. At the same time, the vertical seam of the tower is aligned with the position of the welding head. At this time, the hydraulic rod pushes the welding ring down, and the welding ring is set on the surface of the tower. The air pump supplies air to the air bag contained in the side wall of the welding ring through the air pipe. The air bag gradually deforms to an expanded state, thereby abutting against the surface of the tower, limiting the vertical direction of the welding head, and preventing the welding head from angularly deviating during the descent process, thereby ensuring the welding quality. The hydraulic rod continues to descend, causing the welding head to move in a straight line, and the entire vertical seam is welded without moving the bulky tower, and the welding stability is higher. After welding is completed, the hydraulic rod rises to drive the entire The welding ring moves as a whole. At this time, the solenoid valve is opened, so that the gas inside the airbag quickly flows into the air duct. As the welding temperature continues to rise, the heat conducting plate and the heat conducting rod will quickly sense the temperature and conduct heat to the inside of the adaptive degassing part, thereby causing the shape memory alloy rod to deform. When the temperature exceeds the deformation temperature value of the shape memory alloy rod, the shape memory alloy rod changes from a bent state to a straight state, thereby squeezing and pushing the air blocking parts on both sides to expand toward both ends, realizing the function of adjusting the size of the airflow jet, increasing the jet volume, and quickly blowing and cooling the high-temperature vertical welding seam. After the airbag is deflated, its volume becomes smaller and is re-stored into the storage tank on the inner wall of the welding ring. At this time, the welding ring rises and detaches from the tower.

[0009] Furthermore, the airbag is made of high-temperature resistant elastic material, and the interior of the airbag is also filled with an elastic shaping net. The high-temperature resistant material of the airbag can effectively prevent burns and ruptures caused by excessively high welding temperatures, and the filled elastic shaping net can shape the filling of the airbag to ensure the expansion and fullness of the airbag.

[0010] Furthermore, the air outlet of the air duct is directly opposite to the side of the welding head, and the inner diameter of the air duct is larger than the diameter of the welding head. The air outlet is set at the side of the welding head, which can ensure that the gas ejected from the inside of the airbag can be directly opposite to the vertical seam of the welding, thereby blowing and dissipating the high-temperature vertical seam welding area, greatly improving the welding quality.

[0011] Furthermore, the adaptive air release part includes a disc, a square channel connected to the air duct is opened in the middle of the disc, and the upper and lower inner walls of the disc are fixedly inlaid with heat-conducting rods fixedly connected to the heat-conducting block, and the inner wall of the square channel is fixedly connected to a heat-conducting sheet fixedly connected to the heat-conducting rod. The inner walls of the square channel on both sides are also fixedly connected to air-blocking parts, and a shape memory alloy rod is fixedly connected between the heat-conducting sheet and the air-blocking part. The welding temperature can be sensed and conducted through the heat-conducting block and the heat-conducting rod. When the temperature exceeds the deformation temperature value of the shape memory alloy rod, the shape memory alloy rod changes from a bent state to a straight state, thereby squeezing and pushing the air-blocking parts on both sides to expand toward both ends, thereby realizing the function of adjusting the size of the airflow jet, increasing the jet volume, and quickly blowing and dissipating the heat of the high-temperature welding vertical seam.

[0012] Furthermore, the gas blocking component includes two symmetrically distributed hard substrates, a side sealing gasket is fixedly connected between the two hard substrates, and a plurality of equally spaced adaptive adjustment components are also fixedly connected between the two hard substrates. The side sealing gasket can ensure the sealing effect of the gas blocking component, and the plurality of equally spaced adaptive adjustment components can connect the two hard substrates to assist the extension and contraction of the shape memory alloy rod, thereby realizing the adjustment of the ventilation flow rate, and then adjusting the amount of the jet flow rate according to the welding temperature.

[0013] Furthermore, the adaptive adjustment part is a hollow elliptical structure, and the adaptive adjustment part is made of elastic material, and the side sealing gasket is made of flexible material. The elliptical structure can keep the two hard substrates in a gap state without excessive fitting, and its own elastic properties are used to assist the shape memory alloy rod in sensing the temperature and moving state. The flexible sealing gasket can effectively protect the hard substrate and prevent the end from cracking and damage.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] The tower is placed on the shaping plate by using a lifting mechanism to limit and fix the tower. At the same time, the vertical seam of the tower is aligned with the position of the welding head. At this time, the hydraulic rod pushes the welding ring down, and the welding ring is set on the surface of the tower. The air pump supplies air to the air bag housed in the side wall of the welding ring through the air pipe. The air bag gradually deforms to an expanded state, thereby abutting against the surface of the tower, limiting the vertical direction of the welding head to prevent the welding head from angular deviation during the descent process, thereby ensuring the welding quality. The hydraulic rod continues to descend, causing the welding head to move in a straight line, and the entire vertical seam is welded. There is no need to move the bulky tower, and the welding stability is higher.

[0016] (2) After welding is completed, the hydraulic rod rises, thereby driving the entire welding ring to move as a whole. At this time, the solenoid valve is opened, allowing the gas inside the airbag to quickly flow into the air duct. As the welding temperature continues to rise, the heat conducting plate and the heat conducting rod will quickly sense the temperature and conduct heat to the inside of the adaptive degassing part, thereby causing the shape memory alloy rod to deform. When the temperature exceeds the deformation temperature value of the shape memory alloy rod, the shape memory alloy rod changes from a bent state to a straight state, thereby squeezing and pushing the air blocking parts on both sides to expand toward both ends, realizing the function of adjusting the size of the airflow jet, increasing the jet volume, and quickly blowing and cooling the high-temperature welding vertical seam. After the airbag is deflated, its volume becomes smaller and is re-stored into the storage tank on the inner wall of the welding ring. At this time, the welding ring rises and leaves the tower.

[0017] (3) The airbag is made of high-temperature resistant material, which can effectively prevent burns and ruptures caused by excessive welding temperature. The elastic shaping net filled in the airbag can shape the filling of the airbag to ensure the expansion and fullness of the airbag.

[0018] (4) The air outlet of the air duct is set at the side of the welding head, which can ensure that the gas ejected from the airbag is directly facing the vertical weld seam, thereby blowing and dissipating the heat of the high-temperature vertical weld seam and greatly improving the welding quality.

[0019] (5) The welding temperature can be sensed and conducted through the heat conduction block and the heat conduction rod. When the temperature exceeds the deformation temperature value of the shape memory alloy rod, the shape memory alloy rod changes from a bent state to a straight state, thereby squeezing and pushing the air blocking parts on both sides to expand toward both ends, realizing the function of adjusting the size of the air flow, increasing the air jet volume, and quickly blowing and cooling the high-temperature vertical welding seam.

[0020] (6) A side sealing gasket is fixedly connected between the two rigid substrates, which can ensure the sealing effect of the gas barrier. A plurality of adaptive adjustment parts arranged at equal intervals can connect the two rigid substrates to assist the expansion and contraction of the shape memory alloy rod, thereby realizing the adjustment of the ventilation flow rate, and then adjusting the amount of the jet flow rate according to the welding temperature.

[0021] (7) The adaptive adjustment part is a hollow elliptical structure, and the adaptive adjustment part is made of elastic material. The side sealing gasket is made of flexible material. The elliptical structure can keep the two hard substrates in a gap state, and will not cause excessive fitting. In addition, the elastic properties of the self-adaptive adjustment part assist the shape memory alloy rod in sensing the temperature and moving state. The flexible side sealing gasket can effectively protect the hard substrate and will not cause end cracking and damage. BRIEF DESCRIPTION OF THE DRAWINGS

A bracket 4 is provided below the frame 1, and a shaping disk 5 is fixedly connected to the upper end of the bracket 4. The tower is placed on the upper end of the shaping disk 5. The shaping disk 5 can be set to different heights as needed, and the welding ring 3 is sleeved on the outside of the tower. The welding ring 3 includes an embracing ring 301, and the inner side wall of the embracing ring 301 is provided with a plurality of symmetrically distributed storage tanks 302. The interior of the storage tank 302 is sealed and connected to an air bag 303. An air pump is installed on one side of the frame 1, and the air pump is connected to the airbag 303 through an air pipe. A groove 304 is further provided at a position between the multiple airbags 303 on the holding ring 301, and the groove 304 is directly opposite the vertical seam position of the tower. A welding head 305 is installed on the side wall of the groove 304. An air duct 3011 is provided in the middle of the inner wall between the groove 304 and the airbag 303. A solenoid valve 6 is installed inside the air duct 3011. An adaptive air release part 7 is fixedly connected to the air duct 3011 near the inner wall of the groove 304, and a heat conductive block 8 connected to the adaptive air release part 7 is fixedly embedded in the side wall of the groove 304.

[0036] The airbag 303 is made of a high-temperature resistant elastic material, and the interior of the airbag 303 is also filled with an elastic shaping net. The high-temperature resistant material of the airbag 303 can effectively prevent burns and ruptures caused by excessive welding temperature. The elastic shaping net can shape the filling of the airbag 303 to ensure the fullness of the airbag expansion.

[0037] The air outlet of the air duct 3011 is directly opposite the side of the welding head 305, and the inner diameter of the air duct 3011 is larger than the diameter of the welding head 305. The air outlet is set at the side of the welding head 305, which can ensure that the gas ejected from the airbag 303 can be directly opposite the vertical weld seam, thereby blowing and dissipating heat at the high-temperature vertical weld seam, greatly improving the welding quality.

[0038] The adaptive air release member 7 includes a disc 701, a square channel 702 connected to the air duct 3011 is opened in the middle of the disc 701, and the upper and lower inner walls of the disc 701 are fixedly inlaid with heat-conducting rods 703 fixedly connected to the heat-conducting block 8, and the inner wall of the square channel 702 is fixedly connected to a heat-conducting sheet 704 fixedly connected to the heat-conducting rod 703. The inner walls of the square channel 702 are also fixedly connected to air blocking members 705 on both sides. A shape memory alloy rod 706 is fixedly connected between the heat-conducting sheet 704 and the air blocking member 705. The welding temperature can be sensed and conducted through the heat-conducting block 8 and the heat-conducting rod 703. When the temperature exceeds the deformation temperature value of the shape memory alloy rod 706, the shape memory alloy rod 706 changes from a bent state to a straight state, thereby squeezing and pushing the air blocking members 705 on both sides to expand toward both ends, thereby realizing the function of adjusting the size of the airflow jet, increasing the jet volume, and quickly blowing and cooling the high-temperature vertical welding seam;

[0039] The air barrier 705 includes two symmetrically distributed rigid substrates 7051, with a side sealing gasket 7052 fixedly connected between the two rigid substrates 7051. A plurality of equally spaced adaptive adjustment members 7053 are also fixedly connected between the two rigid substrates 7051.

The multiple equally spaced adaptive adjustment members 7053 connect the two rigid substrates 7051, assisting the expansion and contraction of the shape memory alloy rod 706 to achieve ventilation flow adjustment, thereby simultaneously adjusting the air flow according to the welding temperature.

[0040] The adaptive adjustment member 7053 is a hollow elliptical structure, and the adaptive adjustment member 7053 is made of elastic material, and the side sealing gasket 7052 is made of flexible material. The elliptical structure can maintain the two hard substrates 7051 in a gap state, and will not be over-fitted. The elastic properties of the adaptive adjustment member 7053 are used to assist the shape memory alloy rod 706 in sensing temperature and moving. The flexible side sealing gasket 7052 can effectively protect the hard substrate 7051 and will not cause end cracking or damage.

[0041] In the present invention, a hoisting mechanism is used to place the tower on the shaping plate 5, thereby limiting and fixing the tower. At the same time, the vertical seam of the tower is aligned with the position of the welding head 305. At this time, the hydraulic rod 2 pushes the welding ring 3 down, and the welding ring 3 is sleeved on the surface of the tower. The air pump supplies air to the air bag 303 housed in the side wall of the welding ring 3 through the air pipe. The air bag 303 gradually deforms to an expanded state, thereby abutting against the surface of the tower, limiting the vertical direction of the welding head 303, and preventing the welding head 303 from angular deviation during the descent process, thereby ensuring the welding quality. The hydraulic rod 2 continues to descend, causing the welding head 305 to move in a straight line, and the entire vertical seam is welded without moving the bulky tower, and the welding stability is higher.

[0042] After welding is completed, the hydraulic rod 2 rises, thereby driving the entire welding ring 3 to move as a whole. At this time, the solenoid valve 6 is opened, so that the gas inside the airbag 303 quickly flows into the air duct 3011. As the welding temperature continues to rise, the heat conducting plate 704 and the heat conducting rod 703 will quickly sense the temperature and conduct heat to the inside of the adaptive degassing part 7, thereby causing the shape memory alloy rod 706 to deform. When the temperature exceeds the deformation temperature value of the shape memory alloy rod 706, the shape memory alloy rod 706 changes from a bent state to a straight state, thereby squeezing and pushing the air blocking parts 705 on both sides to expand toward both ends, realizing the function of adjusting the size of the airflow jet, increasing the jet volume, and quickly blowing and cooling the high-temperature welding vertical seam. After the airbag 303 is deflated, its volume becomes smaller and is re-stored into the storage tank 302 on the inner wall of the welding ring 3. At this time, the welding ring 3 rises and leaves the tower.
