Anti-deviation welding equipment for roll-on / roll-off ship columns

Abstract

The present invention discloses an anti-deviating welding device for a column of a rolling ship. The present invention relates to the field of welding technology. In the process of welding two large plates, it is necessary to limit the welding position of the plates so that the welding gap between the plates is reduced. However, in the process of pressing the blocks, due to the presence of burrs and protrusions at the edges of the plates, the pressing of the plates will cause the plates to be pressed down excessively, increasing the welding gap and causing a cold weld. In the process of lateral movement, a protrusion appears at the welding position of the plates, pushing the pressing block to the side away from the slot, and transmitting the pressure to the rubber pad through the connecting column, causing the rubber pad to deform, and changing the clamping position of the clamping block and the slot. The protrusion generates an upward thrust on the pressing block, causing the pressing block to move up through the inclined surface between the clamping block and the slot, avoiding the increase in the downward pressure distance of the plate welding position when the protrusion appears, increasing the welding gap between the plates, and causing a cold weld on the plates after welding is completed.

Description

Technical Field

[0001] The invention relates to the technical field of welding, in particular to an anti-deviating welding device for a roll-on / roll-off ship column. Background Art

[0002] Currently, a ship column refers to a columnar structure used to support or reinforce a part of a ship. For example, a high-pile dock has pile foundations, and the upper part of the pile that is above the water surface is also called a column. These columns support the superstructure and transfer loads deep into the foundation, while also helping to stabilize the bank slope. Welding equipment refers to the various tools, machines, and devices used in the welding process to achieve the connection of metal or other materials.

[0003] In the process of welding two large plates, it is necessary to limit the welding position of the plates to reduce the welding gap between the plates and at the same time press to prevent the plates from shifting. However, in the process of pressing the plates, due to the burrs on the edges of the plates, the pressure on the plates will cause the plates to be pressed down too much, increasing the welding gap and causing a cold weld.

[0009] The top end face of said sliding panel also is provided with an interlocking structure, and the interlocking structure of said sliding panel also is provided with an interlocking structure. The cam is pressed against the plate and the pressing block is moved upwards to prevent the plate from being pressed downwards and the welding position of the plate being shifted.

[0010] Preferably, the welding gun mechanism includes a support beam, a fixing plate is fixedly installed on the outer side of the support beam, and the number of the fixing plates is two, one of the fixing plates is fixedly connected to the inner wall of the wire gun, and the other is fixedly connected to the inner wall of the fixing plate. The end of the outer side of the support beam away from the welding gun is fixedly connected to the fixing bracket, and the side of the support beam away from the fixing plate is fixedly connected to the welding wire wheel, and the top of the outer side of the wire gun is fixedly connected to a wire guide ring, and during the wire guiding process, the wire guide ring utilizes its own arc-shaped annular surface to perform arc-shaped transmission and guide the path of the welding wire, thereby reducing the tortuosity of the welding wire and preventing large creases in the welding wire from causing obstruction of the wire output and affecting the welding process. The top of the support beam is fixedly connected to a wire guide assembly, and the wire guide assembly is located between the welding wire wheel and the wire gun, and a motor is fixedly installed on the top of the wire guide assembly.

[0011] The guide wire assembly of claim 1, wherein the support frame is fixedly mounted on one side of the connecting frame near the wire gun, and the support frame is symmetrically installed along the center position of the axis of the connecting frame, and a limit ring is rotatably installed between the support frame and the limit ring, and the limit ring cooperates with the wire guide ring to guide and limit the output of the welding wire in a straight line to the direction of the wire guide ring, ensuring smooth guiding of the welding wire and avoiding position deviation, cooperating with the wire guide ring to reduce the tortuosity during the welding wire transmission and reduce friction. The inner wall of the connecting frame is fixedly connected with a slot plate, and the slot plate is symmetrically installed along the center position of the axis of the connecting frame, and a column hole is provided on one side of the outer side of the slot plate, and a sliding groove is provided on the other side of the outer side of the slot plate, and a rotating column is rotatably installed at the column hole of the slot plate, the top of the rotating column is fixedly connected to the output end of the motor, the outer side of the motor is fixedly connected to the top of the connecting frame, and a sliding column is slidably installed at the sliding groove of the slot plate, and both ends of the sliding column are provided with protrusions.

[0012] The cam is fixedly mounted on the outside of the gear train and is secured to the gear train with respect to the cam, and the cam is secured to the gear train with respect to the gear train when the cam is in motion.

[0013] The present invention provides an anti-deviation welding device for a roll-on / roll-off ship column. It has the following beneficial effects:

[0014] 1. The anti-deviation welding equipment of the rolling ship column of the vehicle, through the adaptation of the card block and the card slot, during the lateral movement, a bulge appears at the welding position of the plate, pushing the pressure block to the side away from the card slot, and transmitting the pressure to the rubber pad through the connecting column, causing the rubber pad to deform and the clamping position of the card block and the card slot to change. During the movement, the bulge generates an upward thrust on the pressure block, causing the pressure block to move upward through the inclined surface between the card block and the card slot, avoiding the increase of the downward pressure distance of the plate welding position when the bulge appears, causing the plate welding position to shift, and at the same time increasing the welding gap between the plates, resulting in cold welding of the plates after welding is completed, thereby reducing the welding quality.

[0015] 2. The anti-deviation welding equipment of the roll-on / roll-off column of the vehicle cooperates with the column block and the pressure block. The two column blocks press the two plates respectively, and at the same time, the column blocks press the welding positions away from the plates. When the pressure blocks move and stop pressing the welding positions of the plates, the column blocks press the two plates separately to ensure the normal welding and prevent the plates from deviating.

[0016] 3. The anti-deviation welding equipment of the rolling ship column of the vehicle uses the arc-shaped ring surface of the wire guide ring to guide the path of the welding wire in an arc shape during the wire guiding process, thereby reducing the tortuosity of the welding wire and preventing large creases in the welding wire from causing obstruction of the wire output and affecting the welding process. The limiting ring cooperates with the wire guide ring to guide and limit the output of the welding wire, so that the welding wire is guided and limited in a straight line in the direction of the wire guide ring, ensuring smooth guiding of the welding wire and avoiding position deviation. The limiting ring cooperates with the wire guide ring to reduce the tortuosity of the welding wire transmission process and reduce friction.

[0017] 4. The anti-deviation welding equipment of the rolling ship column of the vehicle contacts the welding wire through the ring groove of the groove wheel, uses the pressure of the spring plate to deform the rubber ring, increases the transmission friction between the rubber ring and the welding wire, and ensures the smooth extraction of the welding wire. At the same time, during the transmission process, one of the groove wheels is not installed with a rubber ring to ensure the depth of the ring groove and prevent the welding wire from falling off, causing the welding wire to be out of transmission and making it impossible to transmit the welding wire.

[0032] Hydraulic cylinder 6, which is used to control the welding height. The outer side of the hydraulic cylinder 6 is fixedly connected to a connecting plate 5. The hydraulic cylinder 6 is connected to the gantry's traveling vehicle through the connecting plate 5, and the output end of the hydraulic cylinder 6 is fixedly connected to the top of the frame 1;

[0033] A welding gun mechanism 3 is used for welding column plates and is installed inside the frame 1;

[0034] The pressing mechanism 2 is used to press the plates together to prevent them from shifting during welding, and is installed outside the welding gun mechanism 3;

[0035] Among them, the pressing block mechanism 2 includes a fixing frame 201, the fixing frame 201 is fixedly installed on the outside of the welding gun mechanism 3, and the bottom of the fixing frame 201 is fixedly connected to the bottom of the bottom plate 202, and the bottom of the bottom plate 202 is fixedly installed with a slot frame 203, and one side of the bottom of the slot frame 203 is provided with a square slot, and the bottom of the square slot is provided with a card slot 209, the card slot 209 is inclined downward, and a pressing block 206 is slidably installed at the square slot of the slot frame 203, and a card block 207 is fixedly installed on the outside of the pressing block 206, and the card block 207 is connected to the card slot 209.

The end of the connecting column 210 away from the pressure block 206 is fixedly connected with a slide plate 204. The frame 1 moves downward under the drive of the hydraulic cylinder 6, so that the welding gun mechanism 3 drives the pressure block mechanism 2 to move downward, and the welding gun mechanism 3 is connected to the fixing frame 201. Under the drive, the bottom plate 202 is driven downward by the fixing frame 201, so that the bottom plate 202 drives the slot frame 203 to move to the welding position of the welding plate, and the slot frame 203 is connected to the welding gun mechanism 3. The pressing block 206 and the column block 208 are driven to approach the welding position of the plate to squeeze the welding position of the plate.

During the welding process, the column block 208 and the pressure block 206 are first flattened and then the welding is performed. During the horizontal movement, the column block 208 first squeezes the two plates so that the welding positions of the two plates are parallel and in the same plane. Then the pressure block 206 limits the welding position to facilitate subsequent welding. The column block 208 is symmetrically installed along the center position of the axis of the slot frame 203, and the bottom of the column block 208 and the bottom of the pressure block 206 are in the same horizontal position.

[0036] The second embodiment, based on the first embodiment, see Figure 4As shown, the welding gun mechanism 3 includes a support beam 31, and a fixed plate 35 is fixedly installed on the outer side of the support beam 31. There are two fixed plates 35, and the inner wall of one fixed plate 35 is fixedly connected to the wire gun 33, and the inner wall of the other fixed plate 35 is fixedly connected to the welding gun 32. The welding wire reel is placed in the welding wire wheel 37, and the welding wire passes through the wire guide assembly 36 and enters the wire gun 33. It is led out from the bottom end of the wire gun 33 and energized by the welding gun 32 to weld the led-out welding wire to the material and the plate. At the same time, it is connected to the frame 1 through the support beam 31, and the end of the outer side of the support beam 31 away from the welding gun 32 is connected to the fixed frame 201 is fixedly connected, and a welding wire wheel 37 is fixedly connected to the side of the support beam 31 away from the fixed plate 35, a wire guide ring 34 is fixedly connected to the top of the outer side of the wire gun 33, and a wire guide assembly 36 is fixedly connected to the top of the support beam 31. During the welding process, the wire guide assembly 36 is driven by the motor 38 to move, and the welding wire is evenly driven toward the wire gun 33 during the welding process. The welding wire is restricted by the wire guide ring 34 on the top of the wire gun 33 so that it can smoothly enter the wire gun 33. The wire guide assembly 36 is located between the welding wire wheel 37 and the wire gun 33, and a motor 38 is fixedly installed on the top of the wire guide assembly 36.

[0037] The third embodiment, based on the first and second embodiments, see Figures 5 and 6 As shown, the guide wire assembly 36 includes a connecting frame 361, and a support frame 363 is fixedly installed on one side of the connecting frame 361 close to the wire gun 33. The support frame 363 is symmetrically installed along the center position of the axis of the connecting frame 361, and a limit ring 362 is rotatably installed between the support frames 363. The inner wall of the connecting frame 361 is fixedly connected to a slot plate 364, and the slot plate 364 is symmetrically installed along the center position of the axis of the connecting frame 361, and a column hole is provided on one side of the outer side of the slot plate 364, and a slide groove is provided on the other side of the outer side of the slot plate 364. A rotating column 365 is rotatably installed at the column hole of the slot plate 364, and the top of the rotating column 365 is connected to the output of the motor 38 The ends are fixedly connected, and the motor 38 is connected to the connecting frame 361. The output end drives the rotating column 365 to rotate, and the rotating column 365 drives the groove wheel 367 fixedly connected to the outside of the rotating column 365 to rotate. The welding wire passes through the two groove wheels 367, and the elastic force of the spring plate 368 pushes the sliding column 366 to move toward the column hole in the slide groove of the groove plate 364. The sliding column 366 drives the groove wheel 367 installed at the center position of the outer side to approach the other groove wheel 367. The outer side of the motor 38 is fixedly connected to the top of the connecting frame 361, and the sliding column 366 is slidably installed at the slide groove of the groove plate 364, and both ends of the sliding column 366 are provided with protrusions.

[0038] The center position of the outer side of the sliding column 366 and the rotating column 365 is equipped with a groove wheel 367. The sliding column 366 and the inner wall of the groove wheel 367 are rotatably connected through a bearing. The outer side of the rotating column 365 is fixedly connected to the inner wall of the groove wheel 367. The protrusions at both ends of the sliding column 366 are fixedly connected with a spring plate 368. The side of the spring plate 368 away from the sliding column 366 is fixedly connected to the inner wall of the connecting frame 361. The center position of the outer side of the groove wheel 367 is provided with an annular groove, and is rotatably mounted with the sliding column 366. A rubber ring 369 is fixedly installed in the annular groove of the groove wheel 367. During the approach process, the rubber ring 369 in the annular groove of the groove wheel 367, which is rotatably installed on the outer side of the sliding column 366, contacts one side of the welding wire, pressing the welding wire into the annular groove of the other groove wheel 367. At the same time, the elastic force of the spring plate 368 provides pressure for the contact between the rubber ring 369 and the welding wire, causing the rubber ring 369 to deform under the pressure between the rubber ring 369 and the welding wire, thereby increasing the contact area between the rubber ring 369 and the welding wire.

[0039] During use, the welding equipment is connected to the gantry traveling vehicle through the connecting plate 5, and the welding equipment is fixed on the gantry. The welding equipment is driven by the gantry traveling vehicle to move horizontally, and the frame 1 is driven downward by the hydraulic cylinder 6, so that the frame 1 drives the welding gun mechanism 3 and the briquetting mechanism 2 to move downward to the welding position. Then, the welding equipment is driven by the gantry traveling vehicle to move on the gantry to weld the plates. At the same time, the briquetting mechanism 2 is used to flatten the two welded plates during the walking welding process.

[0040] During the process of welding the plate through the welding gun mechanism 3, the welding wire reel is placed in the welding wire wheel 37, so that the welding wire passes through the wire guide assembly 36 and enters the wire gun 33, is led out from the bottom end of the wire gun 33, and is energized through the welding gun 32, and the led-out welding wire is used to weld the material and the plate, and is connected to the frame 1 through the support beam 31. During the welding process, the wire guide assembly 36 is driven to move by the motor 38, and the welding wire is evenly driven toward the wire gun 33 during the welding process. The welding wire is restricted by the wire guide ring 34 at the top of the wire gun 33 so that it can smoothly enter the wire gun 33.

[0041] The motor 38 is connected to the connecting frame 361, and the output end drives the rotating column 365 to rotate, which drives the groove wheel 367 fixedly connected to the outside of the rotating column 365 to rotate through the rotating column 365, and the welding wire passes between the two groove wheels 367. The elastic force of the spring plate 368 pushes the sliding post 366 to move in the sliding groove of the groove plate 364 toward the column hole. The sliding post 366 drives the groove wheel 367 installed at the outer center position to move closer to the other groove wheel 367. At the same time, during the approaching process, the rubber ring 369 in the ring groove of the groove wheel 367 installed to rotate with the outer side of the sliding post 366 contacts one side of the welding wire, pressing the welding wire into the ring groove of the other groove wheel 367. At the same time, the elastic force of the spring plate 368 provides pressure for the contact between the rubber ring 369 and the welding wire, causing the rubber ring 369 to deform under the pressure between the welding wire, thereby increasing the contact area between the rubber ring 369 and the welding wire.

[0042] During the welding movement, the frame 1 moves downward under the drive of the hydraulic cylinder 6, so that the welding gun mechanism 3 drives the pressure block mechanism 2 to move downward, and the welding gun mechanism 3 is connected to the fixed frame 201. Under the drive, the base plate 202 is moved downward through the fixed frame 201, so that the base plate 202 drives the slot frame 203 to move toward the welding position of the welding plate, and drives the pressure block 206 and the column block 208 to approach the plate welding position through the slot frame 203, and squeezes the plate welding position. At the same time, due to the downward position limitation of the hydraulic cylinder 6, excessive downward pressure is prevented. At the same time, during the horizontal movement welding, the welding positions of the two welded plates are flattened by the cooperation of the column block 208 and the pressure block 206. During the welding process, the column block 208 and the pressure block 206 are first flattened before welding. During the horizontal movement, the two plates are first squeezed by the column block 208 so that the welding positions of the two plates are parallel and in the same plane. Then the pressure block 206 limits the welding position to facilitate subsequent welding.
