Description

Technical Field

[0001] This utility model relates to the field of welding platform technology, and in particular to a movable welding platform for assembling suction buckets. Background Technology

[0002] Offshore wind energy is a safe, clean, and stable renewable energy source, and a strategic choice to alleviate the current energy shortage and solve environmental pollution problems. As wind energy development moves from land to sea and gradually into the deep sea, the special and harsh marine environment places higher demands on the construction and operation of wind turbine foundations and overall structures. In fields such as marine engineering, suction tanks are important basic structural components. With the advancement of marine resource development, the demand and size of suction tanks are constantly increasing, and the installation of suction tanks requires welding operations.

[0003] In existing technologies, when welding suction barrels, a hoisting tool is often used to lift the basket or seat plate close to the welding point, and workers then perform welding work on the basket or seat plate. This method not only occupies the hoisting mechanism, but also prevents multiple welding points from working simultaneously, reducing work efficiency. To address this, a mobile welding platform for assembling suction barrels has been designed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a movable welding platform for assembling suction buckets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A movable welding platform for assembling a suction bucket includes a workbench. A railing is fixedly connected to the top of the workbench. Adjustment mechanisms are provided at both ends and the middle of the top of the workbench away from the railing. Each adjustment mechanism includes an inner sleeve fixedly connected to the top of the workbench. An outer sleeve is slidably fitted onto the outer side of the inner sleeve. Multiple locking slots are equidistantly provided on both sides of the outer sleeve. An outer sleeve is located on the side of the outer sleeve closest to the workbench. Two sliding rods are fixedly connected between the two sides of the inner wall of the top of the inner sleeve. The same locking block is slidably fitted onto both ends of the two sliding rods. Two circular holes adapted to the sliding rods are provided at the bottom of each locking block. Openings adapted to the locking blocks are provided on both sides of the top of the inner sleeve, and the locking blocks and locking slots are adapted to each other. Each of the two card blocks is fixedly connected to a fixing plate on one side, and the two fixing plates are staggered. Each of the two fixing plates has an oblique hole. A guide rod is fixedly connected between the two sides of the top of the inner sleeve, and a screw block is slidably fitted on the circumferential surface of the guide rod. The screw block has a round hole that matches the guide rod. A sliding rod is fixedly connected to the bottom of the screw block, and the sliding rod is slidably connected in the two oblique holes. A lead screw is also rotatably connected between the two sides of the top of the inner sleeve, and the lead screw thread passes through the screw block. A lead screw nut that matches the lead screw is fixedly fitted at the bottom of the screw block. The end of the lead screw near the vertical slot hole passes through the inner sleeve and is fixedly connected to a first synchronous pulley. The lead screw is located inside the vertical slot hole. The inner sleeve has a round hole that matches the lead screw.

[0007] As a further embodiment of this utility model, the adjustment mechanism also includes a second synchronous wheel that is rotatably connected to the outer side of the inner sleeve near the vertical slot hole via a rotating shaft. The second synchronous wheel and the first synchronous wheel are fitted with the same synchronous belt, and a crank is fixedly connected to the outer side of the second synchronous wheel. By rotating the crank in both directions, the locking block can be unlocked, thereby enabling rapid adjustment of the distance between the top plate and the worktable.

[0008] As a further embodiment of this utility model, the top of the three outer sleeves is fixedly connected to the same top plate, and the bottom ends of the top plate away from the workbench are fixedly connected to a locking rod. A first positioning roller is rotatably connected to the middle of the bottom of the top plate. Through the cooperation of the first positioning roller and the second positioning roller, the top plate can be stably locked on the top of the barrel.

[0009] As a further embodiment of this utility model, rectangular holes are provided at both ends of the top of the top plate near the locking rod. A strip frame is fixedly connected to the top of the top plate near the two rectangular holes. A sliding block is slidably connected inside each strip frame. A second positioning roller is rotatably connected to the bottom of each sliding block. The same round rod is fixedly connected between the two ends of each strip frame, and each round rod slides through a matching sliding block. A round hole matching the round rod is provided at the bottom of each sliding block.

[0010] As a further embodiment of this utility model, a fixing block is fixedly connected to both sides of the top center of the top plate, and a bidirectional lead screw is rotatably connected between the two fixing blocks. Both ends of the bidirectional lead screw are screwed with sliders, and a lead screw nut adapted to the bidirectional lead screw is fixedly sleeved on each of the two sliders. A pull rod is rotatably connected to one side of each slider, and the other end of each pull rod is rotatably connected to a nearby sliding block. A worm gear is fixedly sleeved in the middle of the bidirectional lead screw.

[0011] As a further embodiment of this utility model, two U-shaped plates are fixedly connected to the top of the top plate, and a worm gear is rotatably connected between the two U-shaped plates. The worm gear meshes with a worm wheel. One end of the worm gear near the worktable passes through the U-shaped plate and is fixedly connected to a rotating rod. The other end of the rotating rod is fixedly connected to a handwheel. The worm gear drives the worm wheel to rotate, causing the bidirectional lead screw to rotate, thereby moving the slider.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model employs an adjustment mechanism, a top plate, and second and first positioning rollers. Through the cooperation of components on the top plate with the top of the barrel, the device is stably hung on the top of the barrel wall. The adjustment mechanism facilitates the adjustment of the distance between the top plate and the worktable, allowing the worktable to be positioned closer to the welding point. This effectively solves the problems mentioned in the background art, such as the need for hoisting equipment. It achieves the technical effect of suspension installation without occupying hoisting equipment, facilitating the adjustment of the worktable to the welding point, and not occupying ground space. Furthermore, multiple devices can be installed circumferentially when welding circumferential seams, greatly improving work efficiency.

[0014] This utility model: By setting up a first positioning roller, a second positioning roller, a bidirectional lead screw, a worm gear and a worm, the distance between the two second positioning rollers and the first positioning roller can be adjusted, so that the top plate can be stably locked on the top of the barrel.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Reference Figures 1-8A movable welding platform for assembling suction buckets includes a workbench 1. A railing 101 is fixedly connected to the top of the workbench 1. Adjustment mechanisms 2 are provided at both ends and the middle of the top of the workbench 1 away from the railing 101. The adjustment mechanism 2 includes an inner sleeve 204 fixedly connected to the top of the workbench 1. An outer sleeve 201 is slidably fitted on the outside of the inner sleeve 204. Multiple slots 202 are equally spaced on both sides of the outer sleeve 201. An outer sleeve is provided on the side of the outer sleeve 201 closest to the workbench 1. Two sliding rods 210 are fixedly connected between the two sides of the top inner wall of the inner sleeve 204 and the cylinder 201. The same locking block 209 is slidably fitted at both ends of the two sliding rods 210. Two round holes adapted to the sliding rods 210 are opened at the bottom of each locking block 209. Openings adapted to the locking blocks 209 are opened on both sides of the top of the inner sleeve 204, and the locking blocks 209 are adapted to the locking slots 202. Fixing plates 211 are fixedly connected to the sides of the two locking blocks 209 that are close to each other. 1. The two fixed plates 211 are staggered and each has an oblique hole 212. The two oblique holes 212, together with the sliding rod 216, allow the two locking blocks 209 to move closer or further apart synchronously. A guide rod 213 is fixedly connected between the two sides of the top of the inner sleeve 204, and a screw block 215 is slidably fitted on the circumferential surface of the guide rod 213. The screw block 215 has a round hole that matches the guide rod 213. The bottom of the screw block 215 is fixedly connected to the sliding rod 216. 6. A sliding connection is made in two inclined holes 212. A lead screw 214 is rotatably connected between the top two sides of the inner sleeve 204. The lead screw 214 is threaded through the screw block 215. A lead screw nut that matches the lead screw 214 is fixedly sleeved at the bottom of the screw block 215. The end of the lead screw 214 near the vertical slot hole 203 passes through the inner sleeve 204 and is fixedly connected to the first synchronous pulley 205. The lead screw 214 is located inside the vertical slot hole 203. A round hole that matches the lead screw 214 is opened on the inner sleeve 204.

[0027] In this embodiment, the adjustment mechanism 2 also includes a second synchronous pulley 207 rotatably connected to the outer side of the inner sleeve 204 near the vertical slot hole 203 via a rotating shaft. The second synchronous pulley 207 and the first synchronous pulley 205 are fitted with the same synchronous belt 206. A crank handle 208 is fixedly connected to the outer side of the second synchronous pulley 207. By rotating the crank handle 208 in both directions, the position of the control block 209 can be controlled, which facilitates the adjustment of the distance between the top plate 3 and the worktable 1.

[0028] In this embodiment, the top of the three outer sleeves 201 are fixedly connected to the same top plate 3, and the bottom ends of the top plate 3 away from the workbench 1 are fixedly connected to the clamping rods 301. The bottom middle of the top plate 3 is rotatably connected to the first positioning roller 302.

[0029] In this embodiment, rectangular holes 303 are provided at both ends of the top plate 3 near the locking rod 301. A strip frame 4 is fixedly connected to the top of the top plate 3 near the two rectangular holes 303. A sliding block 402 is slidably connected inside each strip frame 4. A second positioning roller 403 is rotatably connected to the bottom of each sliding block 402. The same round rod 401 is fixedly connected between the two ends of each strip frame 4, and each round rod 401 slides through the matching sliding block 402. A round hole matching the round rod 401 is provided at the bottom of each sliding block 402. Through the cooperation of the second positioning roller 403 and the first positioning roller 302, the top plate 3 can be stably locked to the top of the barrel.

[0030] In this embodiment, fixing blocks 5 are fixedly connected to both sides of the top middle of the top plate 3. A bidirectional lead screw 501 is rotatably connected between the two fixing blocks 5, and sliders 502 are screwed to both ends of the bidirectional lead screw 501. A lead screw nut that matches the bidirectional lead screw 501 is fixedly sleeved on both sliders 502. A pull rod 404 is rotatably connected to one side of each slider 502, and the other end of each pull rod 404 is rotatably connected to the adjacent slider block 402. A worm gear 6 is fixedly sleeved in the middle of the bidirectional lead screw 501.

[0031] In this embodiment, two U-shaped plates 7 are fixedly connected to the top of the top plate 3. A worm gear 701 is rotatably connected between the two U-shaped plates 7, and the worm gear 701 meshes with the worm wheel 6. One end of the worm gear 701 near the worktable 1 passes through the U-shaped plate 7 and is fixedly connected to a rotating rod 702. The other end of the rotating rod 702 is fixedly connected to a handwheel. Through the arrangement of the worm gear 701 and the worm wheel 6, the bidirectional lead screw 501 can slide stably with the slider 502 to adjust the distance between the two second positioning rollers 403 and the first positioning roller 302.

[0032] Working principle: Before welding, measure the distance between the welding plane and the hanging point on the cylinder wall. Based on the distance, confirm the position of the working surface. Adjust the distance between the top plate 3 and the workbench 1. Rotate each crank 208, causing the second synchronous pulley 207, synchronous belt 206, and first synchronous pulley 205 to drive the lead screw 214 to rotate. This causes the screw block 215 to move with the sliding rod 216 in the inclined hole 212, bringing the two locking blocks 209 closer together. At this point, use a forklift, crane, or other equipment to lift the top plate 3, ensuring the distance between the workbench 1 and the top plate 3 reaches the required height. Then, reverse the crank 208, causing the locking blocks 209 to engage in the corresponding locking slots 202. This fixes the distance between the workbench 1 and the top plate 3. By rotating the rotating rod 702, the worm gear 701 drives the worm wheel 6 to rotate, bringing the two sliders 502 closer together. Pulling the lever 404 causes the two sliding blocks 402 to slide along the adjacent round rod 401 with the second positioning rollers 403. When the two second positioning rollers 403 are located inside the suction barrel and the first positioning roller 302 is located outside the suction barrel, the position of the two second positioning rollers 403 close to the position between the second positioning rollers 403 and the first positioning roller 302 can precisely lock the top of the suction barrel. Then, with the assistance of forklifts, cranes, or other equipment, the device can be lifted, so that the top plate 3 is stably locked on the top of the suction barrel with the cooperation of the two second positioning rollers 403 and the first positioning roller 302. At the same time, the workbench 1 is close to the outer wall of the suction barrel, and the workers can enter the workbench 1 to work. Multiple of these devices can be installed around the circumference of the barrel. After installation, the working surface is unobstructed and does not occupy lifting equipment, thus improving work efficiency.
