Description

Technical Field

[0001] This utility model relates to the field of tank welding, specifically to a tank welding tilting platform. Background Technology

[0002] During the tank manufacturing process, the welding of circumferential and longitudinal seams requires precise positioning and multi-angle rotation to achieve all-position welding.

[0003] Traditional tank welding platforms generally suffer from low positioning accuracy. These platforms often use mechanical blocks or manual marking for positioning, which is greatly affected by the operator's experience. The verticality deviation of the tank end face can reach 5-10mm, resulting in excessive weld misalignment.

[0004] Therefore, it is very necessary to provide a tank welding and tilting platform to solve the above-mentioned technical problems. Utility Model Content

[0005] Based on the above description, this utility model provides a tank welding and flipping platform to solve the problems of low positioning accuracy and excessive weld deviation that are common in existing tank welding platforms.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A tank welding and tilting platform includes several parallel mounting longitudinal frames and several parallel mounting transverse frames connected to the mounting longitudinal frames in a vertical direction. The mounting longitudinal frames are used to position the two ends of the tank in a vertical direction during the welding process through multiple sets of parallel mounting longitudinal frames. The mounting transverse frames are used to position the sides of the tank in a vertical direction during the welding process through multiple sets of parallel mounting transverse frames. A tilting component and an auxiliary component are connected to the mounting transverse frames. The tilting component is used to drive the tank to tilt. The auxiliary component is used to support the sides of the tank during the rotation of the tank.

[0007] Furthermore, each of the mounting frames is connected in sequence to a frame positioning laser light at both ends. The frame positioning laser light is used to emit laser beams in a vertical direction to both ends of the tank for laser positioning of both ends of the tank.

[0008] Furthermore, each of the mounting crossbeams is connected to a crossbeam positioning laser light at both ends in sequence. The crossbeam positioning laser light is used to emit laser beams in the vertical direction to the two sides of the tank for laser positioning of the two sides of the tank.

[0009] Furthermore, end vertical frames are connected to the mounting cross frames at both ends, and end horizontal cross frames are connected to the end vertical frames. The end horizontal cross frames are used to provide a reference at the upper-middle position of the tank end for positioning the tank during the welding process. End positioning laser lights are connected to the end horizontal cross frames for emitting laser beams at both ends of the tank in a horizontal direction for laser positioning of the tank.

[0010] Furthermore, the flipping component includes a horizontal roller frame connected to the mounting crossbeam at the middle position, and four horizontal rollers rotatably connected to the horizontal roller frame, which are symmetrically arranged in pairs. The horizontal rollers are used to provide rolling support for the bottom of the tank.

[0011] Furthermore, each of the mounting crossbeams in the middle position is provided with several crossbeam adjustment holes, and a crossbeam screw is connected to the crossbeam adjustment hole. The crossbeam screw is connected to the cross roller frame, and the crossbeam screw is used to fix the cross roller frame on different crossbeam adjustment holes to realize the adjustment of the position of the cross roller frame, thereby supporting tanks of different specifications.

[0012] Furthermore, it also includes a lateral tilting drive component, which includes a lateral transmission gear rotatably connected to the lateral roller frame and a lateral transmission rod rotatably connected to the lateral roller frame and connected to each of the lateral transmission gears at the middle position. Horizontal gears are connected to two adjacent lateral rollers. The lateral transmission gears are geared to the lateral transmission gears. A rod gear is connected to one end of the lateral transmission rod. A drive gear is connected to the rod gear. A drive motor is connected to the drive gear.

[0013] Furthermore, rod bearings are connected to the mounting crossbeams at both ends, and the transverse transmission rod is rotatably connected to the rod bearings.

[0014] Furthermore, the auxiliary component includes a side vertical bar connected to each of the mounting crossbars in the middle position, an auxiliary roller frame connected to the side vertical bar, and four auxiliary rollers symmetrically arranged in pairs rotatably connected to the auxiliary roller frame. The auxiliary rollers are used to provide rolling support for the side of the tank.

[0015] Furthermore, the side vertical rod has several auxiliary first adjustment holes from top to bottom. The auxiliary component includes an auxiliary sliding sleeve and an auxiliary screw connected to the auxiliary sliding sleeve. The auxiliary screw is threadedly connected to the auxiliary first adjustment holes. The auxiliary roller frame is slidably connected to the auxiliary sliding sleeve. The auxiliary roller frame has several auxiliary second adjustment holes along the horizontal direction. The auxiliary screw passes through the auxiliary second adjustment holes. The auxiliary first adjustment holes are used to adjust the fixed height of the auxiliary roller frame. The auxiliary second adjustment holes are used to adjust the horizontal position of the auxiliary roller frame.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0017] Multiple sets of parallel longitudinal supports form a vertical support frame, which rigidly fixes both ends of the tank vertically using end slots or clamps. This eliminates axial displacement caused by welding thermal deformation and ensures that the tank axis coincides with the welding fixture baseline within a preset range. Multiple sets of vertically intersecting horizontal supports form a grid-like support surface, which, together with adjustable side auxiliary components, provides stable circumferential support for the tank. This solves the problems of low positioning accuracy and excessive weld deviation commonly found in existing tank welding platforms. Attached Figure Description

A tilting component 3 and an auxiliary component 4 are connected to the mounting transverse frames 2. The tilting component 3 drives the tank to tilt. The auxiliary component 4 supports the sides of the tank during rotation.

[0046] In this embodiment, multiple sets of parallel mounting longitudinal frames 1 form a vertical support skeleton.

[0062] Example 1:

[0063] Multiple sets of parallel mounting frames 1 are horizontally fixed to the ground or workbench. The spacing between the frames is adjusted according to a certain interval, ensuring that the actual spacing can meet the processing requirements of tanks of different specifications. At the same time, ensure that the plane of the frames is perpendicular to the ground.

[0064] Preferably, horizontal mounting frames 2 are sequentially connected to the vertical mounting frame 1 from one end to the other to form a U-shaped frame. The number of horizontal mounting frames 2 is determined according to the general specifications of different processing tanks. Each set of horizontal frames 2 is fixed to the vertical frame 1 by bolts or welding to ensure the rigidity of the frame.

[0065] Preferably, a frame positioning laser light 5 is installed on each of the two ends of each mounting frame 1. The laser light emits vertically upward, and the laser beam is aligned with the vertical center line mark on the end face of the tank by adjusting the angle of the light body.

[0066] Preferably, a crossbeam positioning laser light 6 is installed on each of the two ends of each mounting crossbeam 2. The laser light emits light vertically towards the side of the tank. During debugging, it is ensured that the laser beam coincides with the vertical reference line of the side of the tank.

[0067] Preferably, an end vertical frame 7 is welded to the end of the horizontal frame 2 installed at both ends. The height is adjusted adaptively according to the processing height of the tank. The top of the end vertical frame 7 is horizontally fixed to the end horizontal frame 71. The upper surface of the horizontal frame 71 is engraved with scale lines with an accuracy of 1mm to serve as a reference for positioning the height of the tank.

[0068] Preferably, an end positioning laser lamp 8 is installed at the center of the end horizontal crossbeam 71. The laser beam is emitted in a horizontal direction, and the horizontal height of the laser irradiation end can be adjusted to effectively align with the horizontal center line of the tank end face.

[0069] Preferably, on the mounting crossbeam 2 at the middle position, the crossbeam adjustment hole 21 is selected according to the tank diameter, and the cross roller bracket 31 is fixed in the adjustment hole 21 by the crossbeam screw 22. For example, the cross rollers 32 on both sides are adjusted to support the bottom 1 / 4 height of the tank. At the same time, it is ensured that there are multiple sets of cross roller brackets 31 supporting the tank along the length of the tank.

[0070] Preferably, four horizontal rollers 32 are symmetrically installed on the horizontal roller frame 31. The surface of the rollers is covered with a rubber layer of a certain thickness, such as 10mm, to ensure anti-slip when in contact with the tank. The roller shafts are fixed by bearing seats, allowing the rollers to rotate freely.

[0071] Preferably, the transverse transmission gear 331 is sleeved on the transmission shaft of the transverse roller frame 31 and meshes with the transverse gear 333 at the shaft end of the transverse roller 32. The transmission shafts of adjacent transverse roller frames 31 are connected by transverse transmission rods 332, and rod bearings 34 are installed at both ends of the transmission rod on the transverse frames 2 at both ends to reduce rotational resistance.

[0072] Preferably, the drive motor 336 is fixed to the side of the horizontal roller frame 31, and the motor shaft is connected to the drive gear 335 through a coupling. The drive gear 335 meshes with the rod gear 334. During commissioning, the motor is started to check the rotation synchronization of the horizontal roller 32.

[0073] Preferably, a side vertical rod 41 is fixed on the intermediate mounting frame 2. An auxiliary first adjustment hole 411 is selected according to the height of the tank. The hole spacing of the auxiliary first adjustment hole 411 is 30mm. An auxiliary sliding sleeve 44 is fixed to the vertical rod by an auxiliary screw 45. For example, when the tank height is 2m, the auxiliary sliding sleeve 44 is adjusted to the middle of the vertical rod so that the center height of the auxiliary roller 43 is 1m.

[0074] Preferably, the auxiliary roller frame 42 is pushed to slide horizontally on the auxiliary sliding sleeve 44. The distance between the roller and the side of the tank is adjusted through the auxiliary second adjustment hole 421, which has a hole spacing of 20mm. At the same time, a gap of 5-10mm is reserved. Then, the auxiliary screw 45 is passed through the adjustment hole to fix it, ensuring that the auxiliary roller 43 and the horizontal roller 32 work together to support the tank.

[0075] Preferably, the tank is hoisted onto the tilting platform, with its bottom placed on the horizontal rollers 32 and its sides close to the auxiliary rollers 43.

[0076] Preferably, turn on the longitudinal frame positioning laser light 5 and observe whether the laser beam is projected onto the vertical positioning line on the end face of the tank; turn on the transverse frame positioning laser light 6 and the end positioning laser light 8 to calibrate the horizontal reference line on the side and end face of the tank. If the deviation exceeds 2mm, correct it by adjusting the position of the transverse roller frame 31 or the auxiliary roller frame 42.

[0077] Preferably, the scale lines on the end horizontal crossbeam 71 are used to check whether the height of the upper and middle positions of the tank end is consistent, ensuring that the tank is placed horizontally. The drive motor 336 is started, which drives the horizontal roller 32 to rotate via the horizontal tilting drive component 33, causing the tank to slowly tilt. During the tilting process, the auxiliary roller 43 rolls synchronously to support the side of the tank, preventing it from tilting. When the tank is tilted to the welding angle, such as 45°, the motor is turned off, and the position of the auxiliary roller frame 42 is locked by the auxiliary screw 45 to fix the tank's posture.

[0078] Preferably, the welder welds the tank seam. After completing the welding on one side, the motor is restarted to rotate the tank 180° and the above support and welding steps are repeated.

[0079] Preferably, when changing tanks of different diameters, first loosen the crossbeam screw 22, move the cross roller bracket 31 along the crossbeam adjustment hole 21, adjust the spacing of the cross rollers 32, the formula is: spacing = tank diameter × 0.8, and then tighten the screw to fix it.

[0080] Preferably, the auxiliary screw 45 is loosened, and the height of the auxiliary sliding sleeve 44 is adjusted along the first auxiliary adjustment hole 411. The height is equal to the radius of the tank body (adjustments can be made according to actual use, which should also be within the scope of protection of this application). The horizontal position of the auxiliary roller frame 42 is adjusted through the second auxiliary adjustment hole 421 so that the auxiliary roller 43 is in contact with the side of the tank body.

[0081] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0082] Multiple sets of parallel longitudinal supports form a vertical support frame, which rigidly fixes both ends of the tank vertically using end slots or clamps. This eliminates axial displacement caused by welding thermal deformation and ensures that the tank axis coincides with the welding fixture baseline within a preset range. Multiple sets of vertically intersecting horizontal supports form a grid-like support surface, which, together with adjustable side auxiliary components, provides stable circumferential support for the tank. This solves the problems of low positioning accuracy and excessive weld deviation commonly found in existing tank welding platforms.
