DETAILED DESCRIPTION

[0032] The following examples are for illustrative purposes only and are not intended to limit the scope of the application.

[0033] Example 1

[0034] Reference Figures 1-10The utility model relates to a kind of wind power equipment casting steel structure flip welding auxiliary tool, including bottom plate 1 and two parallelly arranged guide rails 2, guide rail 2 is distributed in the front and back of bottom plate 1, top plate 3 is equipped above bottom plate 1, and top plate 3 lower end is fixedly connected with two front and back arranged vertical plate 4, vertical plate 4 is distributed in the outside of two guide rails 2. Top plate 3 upper end is fixedly installed with first electric telescopic rod 5, and the telescopic end of first electric telescopic rod 5 extends to the below of top plate 3 and is fixedly installed with first welding torch 6, first electric telescopic rod 5 drives first welding torch 6 to lift, for the outside welding of tower barrel weld seam. Two guide rails 2 are slidably connected with two moving assemblies, and two moving assemblies are placed with tower barrel. As shown in FIG. Figure 7 Eight vertical plates 8 are fixedly connected with connecting plate 9, and connecting plate 9 is used to connect each vertical plate 8 and support roller 7, so that four support rollers 7 move synchronously on guide rail 2. Further, the tower barrel to be welded is placed on the moving assembly using a crane, and the tower barrel can be pushed to move horizontally.

[0035] As shown in FIG. Figures 3-5 The left side of bottom plate 1 is provided with a moving mechanism, and the moving mechanism includes two first end plates arranged left and right, a first threaded rod 10 is rotatably connected between the two first end plates, a moving sleeve block 12 is threadedly sleeved on the first threaded rod 10, a right-angle plate 13 is fixedly connected to the upper end of the moving sleeve block 12, a cylinder blocking disc 14 is fixedly connected to the upper end of the right-angle plate 13, a first motor 11 is fixedly installed on the left first end plate to drive the first threaded rod 10 to rotate, the first motor 11 drives the moving sleeve block 12 and the right-angle plate 13 to move horizontally by driving the first threaded rod 10 to rotate, thereby pulling the moving assembly and the cylinder blocking disc 14 on the left side to move horizontally, so that the tower barrel to be welded can be placed on the leftmost moving assembly on the left side of the bottom plate 1.

[0036] As shown in FIG. Figure 5 The right end of the cylinder blocking disc 14 is installed with a plurality of first balls 15 evenly circumferentially distributed, the first balls 15 are in rolling contact with the left end of the tower barrel on the left side, and the cylinder blocking disc 14 plays a limiting role on the tower barrel, so that the tower barrel cannot move to the left on the moving assembly, and the arrangement of the first balls 15 does not affect the rotation of the tower barrel on the moving assembly.

[0037] As shown in FIG. Figure 7As shown, the upper end of each connecting plate 9 is fixedly connected with two plug boxes 16, which are located in the gap between the connecting plate 9 and the tower drum. The plug box 16 is provided with a left-right through cavity, which is in a rectangular structure. The upper end of the plug box 16 is provided with a limiting hole 17, and the two plug boxes 16 on the right side are each provided with a limiting plug. The limiting plug includes a plug rod 18 which is slidably arranged in the plug box 16 and has a rectangular cross section. The plug rod 18 is matched with the cavity of the plug box 16, facilitating horizontal insertion into the plug box 16 and preventing rotation. The right end of the plug rod 18 is fixedly connected with a blocking drum plate 19, and the left end of the blocking drum plate 19 is mounted with a second ball 32. The second ball 32 is in rolling contact with the right end of the tower drum on the right side, which is used to block the right movement of the tower drum and does not affect the rotation of the tower drum. The plug rod 18 is provided with an extension cavity 20, and the extension cavity 20 is provided with a lifting plate 21. Two vertical rods 22 are fixedly connected between the upper and lower inner walls of the extension cavity 20. The vertical rods 22 penetrate through the lifting plate 21 and are slidably connected with the lifting plate 21. The lifting plate 21 can vertically lift under the limitation of the two vertical rods 22. Two first springs 23 are fixedly connected between the lifting plate 21 and the inner bottom wall of the extension cavity 20. The first spring 23 is a tensile spring, which is used for the reset of the lifting plate 21. The upper end of the lifting plate 21 is fixedly connected with a limiting column 24 which is matched with the limiting hole 17. The upper end of the limiting column 24 penetrates through the inner top wall of the extension cavity 20 and extends into the limiting hole 17, which plays a limiting role and locks the plug rod 18, so that it cannot move. When the plug rod 18 is locked, the limiting plug is locked on the corresponding plug box 16, thereby limiting the tower drum.

[0038] The right end of the lifting plate 21 is fixedly connected with a contact protrusion 25, which is a cylindrical block welded on the lifting plate 21. The right side inner wall of the extension cavity 20 is provided with a movable slot 26, and the movable slot 26 is slidably connected with a push block 27. The left end of the push block 27 is provided with an inclined surface and extends into the extension cavity 20. The inclined surface is in sliding contact with the contact protrusion 25, so that the lifting plate 21 can be lifted and displaced by the push block 27. The second spring 28 is fixedly connected between the push block 27 and the right side inner wall of the movable slot 26. The second spring 28 is a compression spring, which can keep the left end of the push block 27 in the leftmost position in the normal state, so that the lifting plate 21 and the limiting column 24 remain in the highest position. The right end of the push block 27 is fixedly connected with a pull rod 29, and the right end of the pull rod 29 extends to the right side of the blocking drum plate 19 and is fixedly connected with a pull block 30. The pull rod 29 penetrates through the plug rod 18 and the blocking drum plate 19 and is slidably connected with them. The right side of the blocking drum plate 19 is fixedly connected with a handrail 31. Under the influence of external force, the second spring 28 remains in a compressed state, and the left end of the push block 27 remains in the extension cavity 20. The lifting plate 21 is in the highest position by the action of the inclined surface and the contact protrusion 25. The two first springs 23 are in a stretched state, and the limiting column 24 remains inserted into the limiting hole 17, thereby locking the position of the plug rod 18 and fixing the position of the blocking drum plate 19, thereby effectively limiting the tower drum.

[0039] It should be noted that, only by pulling the block 30 and the pull rod 29 to the right to pull the block 27, the left end is moved to the active slot 26, the lifting plate 21 and the limiting column 24 can be moved downward under the action of the first spring 23, so that the limiting column 24 moves out of the limiting hole 17, the locking of the plug rod 18 is released, and the limiting plug can be removed.

[0040] The inner side welding mechanism is arranged on the right side of the bottom plate 1, the inner side welding mechanism comprises two second end plates which are arranged at intervals left and right, two slide rods 33 are fixedly connected between the two second end plates, a moving plate 34 is commonly and slidably connected on the two slide rods 33, a second threaded rod 35 is rotatably connected between the two second end plates, the second threaded rod 35 penetrates through the moving plate 34 and is threadedly connected with the moving plate 34, a second motor 36 for driving the second threaded rod 35 to rotate is fixedly installed on the second end plate located on the right side, and the second motor 36 can drive the moving plate 34 to move transversely through the second threaded rod 35. First air cylinders 37 are fixedly installed at the front and rear ends of the moving plate 34, control boxes 38 are fixedly connected on the extension ends of the two first air cylinders 37 through fixing members, a cross plate 39 is fixedly connected on the left end of the control box 38, and the two first air cylinders 37 work synchronously to drive the control box 38 to vertically ascend and descend. When the first air cylinders 37 are in the contracted state, the positions of the control box 38 and the cross plate 39 are all lower than the height of the lower end of the connecting plate 9, so that the moving assembly can be conveniently moved above the inner side welding mechanism. When the first air cylinders 37 drive the control box 38 and the cross plate 39 to move upward, the cross plate 39 can be moved to the position height of the inner circle of the tower drum, and then the driving action of the second motor 36 is matched to move the cross plate 39 from the right side of the tower drum to the inside of the tower drum.

[0041] A rectangular overturning opening 40 is formed in the cross plate 39, and an overturning block 41 is rotatably connected in the overturning opening 40. The overturning block 41 is arranged leftward relative to the rotation axis of the overturning opening 40. A rotary air cylinder 44 for driving the overturning block 41 to overturn is fixedly installed on the rear end of the cross plate 39 and at the position corresponding to the rotation axis of the overturning block 41. The rotary angle of the rotary air cylinder 44 is 90 degrees. A second electric telescopic rod 42 is fixedly installed on the end portion of the overturning block 41. A second welding gun 43 is fixedly installed on the extension end of the second electric telescopic rod 42. Before welding work is performed, the overturning block 41, the second electric telescopic rod 42 and the second welding gun 43 are all located in the overturning opening 40, and do not affect the normal movement of the moving assembly. When the cross plate 39 is moved into the tower drum, the rotary air cylinder 44 can drive the overturning block 41 to overturn by 90 degrees, so that the second electric telescopic rod 42 and the second welding gun 43 are in the vertical state, and the second welding gun 43 faces the top wall in the tower drum, thereby facilitating the welding work on the inner side of the tower drum.

[0042] As Figure 1 and Figure 2As shown, the third cylinder 47 is fixedly installed in the inner side of the front vertical plate 4, the telescopic end of the third cylinder 47 is transversely arranged and fixedly connected with the plug-in box 48, the plug-in box 48 is longitudinally slidably inserted with the movable push plate 49, the movable push plate 49 can be moved to the right side of the moving assembly on the right side by pushing, so that the moving assembly is gradually moved left by the third cylinder 47, thereby facilitating the welding surface contact work of the two tower drums.

[0043] Specifically, after the tower drum on the left side is placed on the corresponding moving assembly, it can be moved to the position below the top plate 3 by the first motor 11, and the welding end surface thereof is corresponded with the position of the first welding gun 6, then the tower drum on the right side is placed on the moving assembly on the right side, and after being pushed to the position close to the tower drum on the left side by the electric trolley, it is further moved left by the third cylinder 37 and the movable push plate 49 until the welding end surfaces of the two tower drums are completely contacted and fitted, at this time, the position of the weld formed is directly corresponded with the position of the first welding gun 6.

[0044] The second cylinder 45 is fixedly installed on the two vertical plates 4, the telescopic end of the second cylinder 45 extends to the position below the top plate 3 and is provided with the electric roller 46, after the weld is formed, the corresponding electric roller 46 can be moved by the second cylinder 45, so that the two electric rollers 46 are simultaneously contacted with the two tower drums, and then the synchronous rotation of the electric rollers 46 can drive the two tower drums to rotate. Further, when the second welding gun 43 is moved to the weld position by the inner welding mechanism, it is arranged opposite to the first welding gun 6, only the first welding gun 6 and the second welding gun 43 are started at the same time, and the rotation of the two tower drums is matched, the synchronous girth seam welding work of the inner and outer sides of the tower drum can be carried out.

[0045] When the welding of the tower drum needs to be continued, the inner welding mechanism is first reset, that is, it is moved to the position between the two guide rails 2 and is horizontally placed. A moving assembly is additionally installed on the guide rail 2 on the right side of the inner welding mechanism, and the two limiting inserts are disassembled and assembled on the moving assembly, and the tower drum which has been welded is moved left by the moving mechanism, so that the welding end surface on the right side of the tower drum is moved below the first welding gun 6, and then the next tower drum is moved to the welding position by the additionally installed moving assembly, thereby the synchronous girth seam welding work of the inner and outer sides can be continuously carried out.

[0046] Specifically, the conventional process needs to first complete the outer girth seam welding, and then manually weld the inner side, which takes about 40-60 minutes per section; the present tooling synchronously works by the inner and outer double welding guns (the first welding gun 6 and the second welding gun 43), the single welding time is shortened to 15-20 minutes per section, and the efficiency is improved by 60%-75%.

[0047] Support multi-section tower pipeline welding (through the movement of the assembly 9 and limit plug quick disassembly), replace the time-consuming ≤5 minutes, more than 70% of the traditional repositioning auxiliary time saving.

[0048] The first welding gun 6 and the second welding gun 43 are precisely aligned with the weld (error ≤0.5mm), which ensures uniform molten depth inside and outside, and avoids stress concentration defects caused by unilateral welding. Synchronous welding makes the heat input symmetrically distributed, and the roundness deviation of the tower after welding is ≤1.2mm (the deviation of the traditional process is ≥3mm).

[0049] Effectively avoid high-risk operations, completely replace manual welding inside the tower, eliminate the risk of closed space operation, and effectively improve the incidence of safety accidents. Only one operator is needed for a single device, which reduces 50% of the labor demand compared with the traditional two-person collaborative mode (one external welder + one internal welder).

[0050] Example two

[0051] Reference Figures 11-12 , the case can also have other operation modes on the basis of example one, specifically, two front and rear interval setting positioning seats 50 are fixedly connected on the bottom plate 1, two arc-shaped placing seats 51 are fixedly connected between the two positioning seats 50, for placing the tower just welded. The bottom plate 1 is provided with support piers 52 on the left and right sides, and the opposite ends of the two support piers 52 are installed with electric turntables 53, the fourth cylinders are installed on the two electric turntables 53, the inner support assemblies 54 are installed on the extension ends of the two fourth cylinders, and the electric turntables 53 can drive the corresponding fourth cylinders to rotate, so as to drive the corresponding inner support assemblies 54 to rotate. The inner support assembly includes a bidirectional electric guide rail fixedly installed on the extension end of the fourth cylinder, and two support blocks are slidably connected on the bidirectional electric guide rail. The bidirectional electric guide rail can drive the two support blocks to move relative to each other, so as to facilitate the movement of the support blocks into the tower, and then the support blocks are tightly contacted with the inner wall of the tower. When the four support blocks are tightly contacted with the inner wall of the tower at the same time, only the synchronous rotation of the two electric turntables 53 can drive the tower to rotate.

[0052] The positioning seat 50 is provided with a notch at the center of the upper end, and the notch is fixedly connected with a polishing machine fixing piece 55 on both sides. The polishing machine is fixed in the notch position, and the weld position of the tower after welding is just aligned with the notch. The polishing machine can polish the weld of the tower during rotation. Polishing can remove oxides, slag, pores and other defects on the surface of the weld, and enhance the integrity and sealing of the weld. The positioning seat 50 is fixedly connected with a mounting seat 56 at the upper end, and the mounting seat 56 is used to install a monitoring element (the monitoring element is prior art, which is not described here). The polishing effect of the weld is guaranteed.

[0053] Further solve the problem that the weld of the tower drum needs to be polished by manual after welding, and improve the processing efficiency of the wind power tower drum.

[0054] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
