Abstract
Description
Technical Field
[0001] This application relates to the technical field of steel pipe tower welding, and particularly relates to an auxiliary device for welding internal and external welds. Background Art
[0002] Steel pipe towers play an important role in modern architecture and power transmission. As an important part of power transmission, they have an irreplaceable position in long-distance power transmission. To ensure the safety and stability of steel pipe towers, welding is one of the key processes, especially during the multi-section assembly process. However, the fixation of the weld position during welding directly affects the welding quality and assembly accuracy, so the design of the fixing device is particularly important.
[0003] Currently, steel pipe towers are mainly manufactured by welding two semi-cylinders together. Usually, they are hoisted and welded. If both semi-cylinders are hoisted, during welding, the welding position between the two semi-cylinders is prone to dislocation, thus affecting the welding effect. Therefore, further improvement is needed. Utility Model Content
[0004] To improve the welding effect of steel pipe towers, this application provides an auxiliary device for welding internal and external welds.
[0005] An auxiliary device for welding internal and external welds provided by this application adopts the following technical solution:
[0006] An auxiliary device for welding internal and external welds includes a plurality of fixing components arranged along the length direction of the semi-cylinder. Two fixing components are arranged at intervals along the axis of the semi-cylinder. The fixing component includes a first fixing plate and a second fixing plate respectively arranged on the inner and outer sides of the semi-cylinder and a fixing member for fixing the first fixing plate and the second fixing plate to abut against the semi-cylinder. The first fixing plate and the second fixing plate are both arc-shaped. The first fixing plate and the second fixing plate both abut against the two semi-cylinders. The fixing member includes a bolt passing through the first fixing plate and the second fixing block and a nut threadedly connected to the bolt.
[0007] By adopting the above technical solution, after the first fixing plate and the second fixing plate are respectively abutted against the inner and outer walls of the semi-cylinder, the bolt is passed through the first fixing plate and the second fixing plate and threadedly connected to the nut. Since the first fixing plate and the second fixing plate are both arc-shaped and relatively tightly abut against the two semi-cylinders, the lower semi-cylinder is fixedly connected to the upper semi-cylinder. The upper semi-cylinder can be hoisted to drive the lower semi-cylinder. The first fixing plate and the second fixing plate are installed on the semi-cylinder. Operations such as installation and disassembly are convenient, and the dislocation of the two semi-cylinders is reduced, thereby improving the welding effect.
[0008] Preferably, a plurality of the fixing members are arranged at intervals along the width direction of the first fixing plate.
[0009] By adopting the above technical solution, a plurality of fixing members are arranged at intervals along the width direction of the first fixing plate to improve the fixing effect of the first fixing plate and the second fixing plate on the two semi-cylinders, so as to reduce the possibility of the lower semi-cylinder falling during hoisting, and the influence on subsequent weld welding after a plurality of first fixing plates and second fixing plates are provided can be reduced.
[0010] Preferably, one bolt passes through the two first fixing plates and the two second fixing plates, and three nuts are arranged on one bolt.
[0011] By adopting the above technical solution, by passing one bolt through the two first fixing plates and the two second fixing plates and correspondingly arranging three nuts, the nuts are rotated to respectively abut against the first fixing plate, the first fixing plate and the second fixing plate on the other side for fixing, and the first bolt can perform a certain tension on the first fixing plates and the second fixing plates on both sides to further improve the alignment effect between the two semi-cylinders.
[0012] Preferably, a convex block protrudes from the middle of the second fixing plate toward the surface away from the semi-cylinder.
[0013] By adopting the above technical solution, by providing the convex block, the convex block can be pinched so that the bolt can be threaded with the nut after passing through the first fixing plate and the second fixing plate, thereby reducing the installation difficulty.
[0014] Preferably, a first elastic pad is arranged on the side wall of the convex block, and the bolt part or the nut is used to abut against the first elastic pad.
[0015] By adopting the above technical solution, by providing the first elastic pad, when the bolt or the nut is rotated, it can abut against the first elastic pad to reduce the possibility of the bolt part or the nut slipping and disengaging under the influence of external force, so as to further improve the fixing effect on the two semi-cylinders.
[0016] Preferably, it further includes a hook and a lifting rope arranged on the hook. The number of the hooks corresponds to the number of the convex blocks, and a through hole for the hook to pass through is formed through the upper surface of the convex block.
[0017] By adopting the above technical solution, a through hole is formed in the convex block for the hook to pass through, which can reduce the possibility of relative slippage between the hook and the semi-cylinder when the hook is directly hung on the semi-cylinder, and the two semi-cylinders fixed under the fixing component are also relatively stable during hoisting.
[0018] Preferably, the curvature of the first fixing plate is greater than that of the semi-cylinder, and the curvature of the second fixing plate is less than that of the semi-cylinder.
[0019] By adopting the above technical solution, making the curvature of the first fixing plate greater than that of the semi-cylinder and the curvature of the second fixing plate less than that of the semi-cylinder can reduce the possibility of scraping the semi-cylinder when abutting against it.
[0020] Preferably, there is a gap between the first fixing plate, the second fixing plate and the semi-cylinder, and a second elastic pad for filling the gap is provided on the surfaces of the first fixing plate and the second fixing plate close to the semi-cylinder.
[0021] By adopting the above technical solution, by providing a second elastic pad for filling the gap between the first fixing plate, the second fixing plate and the semi-cylinder, the friction between the first fixing plate, the second fixing plate and the semi-cylinder can be increased, so as to further improve the fixing effect between the two semi-cylinders, thereby improving the subsequent welding effect of the steel pipe tower.
[0022] In summary, the utility model has the following beneficial effects:
[0023] After the first fixing plate and the second fixing plate are respectively abutted against the inner and outer walls of the semi-cylinder, bolts are passed through the first fixing plate and the second fixing plate and threadedly connected with nuts. Since both the first fixing plate and the second fixing plate are arc-shaped and are relatively closely abutted against the two semi-cylinders, the lower semi-cylinder is fixedly connected to the upper semi-cylinder. The upper semi-cylinder can be hoisted to drive the lower semi-cylinder. Installing the first fixing plate and the second fixing plate on the semi-cylinder makes operations such as installation and disassembly convenient, and the dislocation of the two semi-cylinders is reduced, thereby improving the welding effect.

Detailed implementation mode
[0029] The following will further elaborate on this application in conjunction with the attached Figures 1-4 drawings for a more detailed description.
[0030] An embodiment of this application discloses an internal and external weld welding auxiliary device.
[0031] Embodiment 1:
[0032] An internal and external weld welding auxiliary device, referring to Figure 1 , includes several fixing components 2 arranged along the length direction of the semi-cylinder 1, a hook 3 hung on the semi-cylinder 1, and a lifting rope 4 fixedly connected to the hook 3.
[0033] Referring to Figure 1 , Figure 2 , among which, there are specifically two fixing components 2 arranged along the length direction of the semi-cylinder 1, and two are arranged at intervals along the axis of the semi-cylinder 1, so a total of four are set. The fixing component 2 specifically includes a first fixing plate 21 and a second fixing plate 22 respectively arranged on the inner and outer sides of the semi-cylinder 1, and a fixing piece 23 for fixing the first fixing plate 21 and the second fixing plate 22 to abut against the semi-cylinder 1. In this embodiment, both the first fixing plate 21 and the second fixing plate 22 are arc-shaped, the curvature of the first fixing plate 21 is greater than that of the semi-cylinder 1, the curvature of the second fixing plate 22 is less than that of the semi-cylinder 1, and both the first fixing plate 21 and the second fixing plate 22 abut against the two semi-cylinders 1.
[0034] In this embodiment, several fixing pieces 23 are arranged at intervals along the width direction of the first fixing plate 21, specifically two are set. The fixing piece 23 specifically includes a bolt 231 passing through the first fixing plate 21 and the second fixing block, and a nut 232 threadedly connected to the bolt 231. The bolt 231 passes through the weld between the two semi-cylinders 1.
[0035] Furthermore, to facilitate subsequent threading of the bolt 231 through the first fixing plate 21 and the second fixing plate 22 and then threadedly connecting with the nut 232, thereby reducing the installation difficulty, a convex block 5 protrudes from the middle of the second fixing plate 22 towards the surface away from the semi-cylinder 1 for gripping.
[0036] The implementation principle of an internal and external weld welding auxiliary device in an embodiment of the present application is as follows: After the first fixing plate 21 and the second fixing plate 22 are respectively abutted against the inner and outer walls of the semi-cylinder 1, the bolt 231 is passed through the first fixing plate 21 and the second fixing plate 22 and threadedly connected to the nut 232. Since both the first fixing plate 21 and the second fixing plate 22 are arc-shaped, they are relatively closely abutted against the two semi-cylinders 1 to fixedly connect the lower semi-cylinder 1 to the upper semi-cylinder 1. The upper semi-cylinder 1 can be hoisted to drive the lower semi-cylinder 1. The first fixing plate 21 and the second fixing plate 22 are installed on the semi-cylinder 1, and operations such as installation and disassembly are convenient, and the dislocation of the two semi-cylinders 1 is reduced, thereby improving the welding effect.
[0037] Embodiment 2:
[0038] Referring to Figure 3 、 Figure 4 , the difference from Embodiment 1 is that the number of hooks 3 is correspondingly set to the number of bumps 5. A through hole 51 for the hook 3 to pass through is formed through the upper surface of the bump 5 for the hook 3 to pass through, which can reduce the possibility of relative slippage between the hook 3 and the semi-cylinder 1 when the hook 3 is directly hung on the semi-cylinder 1, and the two semi-cylinders 1 are also relatively stably abutted during the hoisting process after being fixed by the fixing assembly 2.
[0039] In this embodiment, one bolt 231 passes through two first fixing plates 21 and two second fixing plates 22. At this time, three nuts 232 are provided on one bolt 231, and the three nuts 232 respectively abut against the first fixing plate 21 near the bolt head of the bolt 231 and the first fixing plate 21 and the second fixing plate 22 on the other side.
[0040] Furthermore, a first elastic pad 6 is provided on the side wall of the bump 5, and the bolt part of the bolt 231 or the nut 232 is used to abut against the first elastic pad 6 to reduce the possibility of relative slippage between the bolt 231 and the nut 232.
[0041] Since the curvature of the first fixing plate 21 is greater than the curvature of the semi-cylinder 1, and the curvature of the second fixing plate 22 is less than the curvature of the semi-cylinder 1, there will be a gap between the first fixing plate 21, the second fixing plate 22 and the semi-cylinder 1. In this embodiment, a second elastic pad 7 for filling the gap is provided on the surface of the first fixing plate 21 and the second fixing plate 22 close to the semi-cylinder 1.
[0042] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
