Description

Technical Field

[0001] The utility model relates to the technical field of power pole tower production, in particular to a welding device for power pole tower production. Background Art

[0002] The pole tower is used to support the transmission line. It is mostly made of steel. In order to ensure its stability and to set up the transmission line, there are a lot of connecting rods on the pole tower. These connecting rods are generally made of steel after rolling and then welding the gaps. Since the welding point is a continuous straight line, it is also called straight seam welding.

[0003] In the prior art, when welding the side panels of a power tower, it is necessary to first splice and fix the adjacent side panels and then weld them. However, after welding one side, the side panel needs to be disassembled, turned over and re-fixed, and then welded on the other side. This operation is relatively cumbersome. For this reason, we propose a welding device for power tower production. Utility Model Content

[0004] The utility model aims to provide a welding device for producing power pole towers, which can turn over welded side plates without re-fixing.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A welding device for producing power poles and towers, comprising:

[0007] A base, a support base is installed on the top of the base, the number of the support bases is two, both support bases are rotatably connected with a rotating shaft, the end of the rotating shaft is fixedly connected with an adjustment base, the inside of the adjustment base is rotatably connected with a first threaded rod, the first threaded rod is rotatably connected with a moving frame, the moving frame is rotatably connected with a second threaded rod, and the bottom end of the second threaded rod is rotatably connected with a fixed plate;

[0008] A storage box, the storage box is fixedly connected to one of the side walls of the support seat, a worm is rotatably connected inside the storage box, a worm wheel is meshingly connected to the outer surface of the worm wheel, and the worm wheel is fixed to the rotating shaft;

[0009] A cross bar is fixed on the support seat, and a welding machine is slidably connected inside the cross bar.

[0010] Based on the above technical solution, its use principle and the technical effects produced are as follows:

[0011] When it is necessary to weld the plates of the power pole tower, first place the plates on the mobile frame, then turn the second handle to drive the fixed plate to move downward to clamp and fix the plates. After the two plates are fixed, turn the first handle to drive the first threaded rod to rotate, so that it drives the two mobile frames to move toward the middle at the same time, and splice the two fixed steel plates together. At this time, the splicing seam of the two plates will be located below the welding machine. Then the staff holds the handle and starts the welding machine to perform straight seam welding on the steel plates. After the top welding is completed, turn the third handle to drive the worm to rotate, and the worm gear is driven by the worm to rotate, thereby driving the shaft to rotate. When the shaft rotates, it will drive the adjustment seat to flip, so that the plate can be flipped, which is convenient for welding the bottom surface after the top surface welding is completed. There is no need to disassemble and re-fix the plate, which is convenient and practical. It should be noted that there is a certain damping between the shaft and the support seat, so when the steel plate is flipped, no deflection or shaking will occur, affecting the welding effect.

[0012] In a preferred example, the utility model can be further configured as follows: the two support seats are arranged symmetrically on the left and right, and the support seats are fixedly connected to the base by bolts.

[0013] In a preferred example, the utility model can be further configured as follows: the number of the rotating shafts is two, and one of the rotating shafts passes through the support seat and extends into the storage box.

[0019] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0020] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0021] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0022] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.);

[0023] An active connection is a connection in which parts or components are fixed so that they can move relative to each other.

[0024] The above technical solution of the utility model has the following beneficial technical effects:

[0025] 1. In the utility model, by cooperating with each other of the adjustable seat, the movable frame, the fixed plate and other structures, the side panels of different specifications can be spliced ​​and fixed, and the connecting seam after splicing is just located directly below the welding machine. The staff only needs to move the welding machine to perform straight seam welding on the side panels without the need for butt seam welding.

[0026] 2. In the utility model, by cooperating with each other among the worm, worm wheel, rotating shaft and other structures, the plate can be turned over after the top surface welding is completed, without the need to disassemble and re-fix the plate, which is simple to operate, convenient and practical.

[0033] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure. It should be noted that the embodiments of the present utility model and the features in the embodiments can be combined with each other without conflict.

[0034] According to the concept of this application, Figures 1 to 4 The following describes an embodiment of a welding device for producing power poles and towers, which is used for welding the flat plates of power poles and towers. Specifically, the welding device for producing power poles and towers is constructed as an integrated structure, which has three components, namely a base, a storage box and a cross bar. Through the cooperation of the adjustment seat, the movable frame, the fixed plate and other structures, the side panels of different specifications can be spliced ​​and fixed, and the connecting seam after splicing is just located directly below the welding machine. The staff only needs to move the welding machine to perform straight seam welding on the side panels, and there is no need to perform seam matching. Moreover, through the cooperation of the worm, worm wheel, rotating shaft and other structures, the plate can be flipped over after the top surface welding is completed, without the need to disassemble and re-fix the plate. The operation is simple, convenient and practical.

[0035] Combination Figure 1-4 As shown, the utility model provides a welding device for producing power poles and towers, comprising:

[0036] A base 1, a support base 2 is installed on the top of the base 1, the number of the support bases 2 is two, the two support bases 2 are rotatably connected with a rotating shaft 3, the end of the rotating shaft 3 is fixedly connected with an adjusting base 4, the inside of the adjusting base 4 is rotatably connected with a first threaded rod 5, the first threaded rod 5 is rotatably connected with a moving frame 6, the moving frame 6 is rotatably connected with a second threaded rod 7, and the bottom end of the second threaded rod 7 is rotatably connected with a fixed plate 8;

[0037] A storage box 9 is fixedly connected to one of the side walls of the support seat 2. A worm 10 is rotatably connected inside the storage box 9. A worm wheel 11 is meshingly connected to the outer surface of the worm 10. The worm wheel 11 is fixed to the rotating shaft 3.

[0038] The cross bar 12 is fixed on the support seat 2, and a welding machine 13 is slidably connected inside the cross bar 12.

[0039] The support seat 2 is mainly used to provide support. In some embodiments, the overall shape of the support seat 2 can be set to a rectangular or cylindrical shape. For the technical solution of the present application, the overall shape of the support seat 2 is set to a rectangular shape, and the two support seats 2 are arranged symmetrically on the left and right, and the support seat 2 is fixedly connected to the base 1 by bolts.

[0040] According to the technical solution of the present application, there are two rotating shafts 3, one of which is rotatably connected to the side wall of the support seat 2 through a bearing, and the other rotating shaft 3 passes through the other support seat 2 and extends into the storage box 9, and the end of the rotating shaft 3 is rotatably connected to the inner wall of the storage box 9 through a bearing.

[0041] According to the technical solution of the present application, the left and right sections of the first threaded rod 5 are arranged with opposite thread directions, and two movable frames 6 are symmetrically arranged on each first threaded rod 5. The side walls of the two movable frames 6 are provided with first threaded holes adapted to the first threaded rod 5. The first threaded rod 5 is arranged through the adjustment seat 4, and one end of the first threaded rod 5 is fixedly connected to a first turning handle 14. Rotating the first turning handle 14 drives the first threaded rod 5 to rotate, which can drive the two movable frames 6 to move along the adjustment seat 4, thereby making the two movable frames 6 approach or move away from each other, which is convenient for adapting the connecting steel plate of the power pole tower.

[0042] Furthermore, a second threaded hole compatible with the second threaded rod 7 is opened on the side wall of the movable frame 6, and a second handle 15 is fixedly connected to the top of the second threaded rod 7. Turning the second handle 15 drives the second threaded rod 7 to rotate, so that the second threaded rod 7 can drive the fixed plate 8 to move on the movable frame 6, thereby facilitating the clamping and fixing of the steel plate. The technical solution of the present application is mainly for horizontal and transverse fixation of two steel plates to be spliced. Fixing in this way is convenient for lifting the steel plates from above to the top of the movable frame 6 with the help of external lifting equipment, and then clamping and fixing the steel plates one by one, which is convenient for rapid loading.

[0043] On the other hand, one end of the worm 10 is rotatably connected to the storage box 9 through a bearing, and the other end is arranged through the storage box 9, and the penetrated end is fixedly connected to a third handle 16. When the third handle 16 is rotated, the worm 10 is driven to rotate, and the worm wheel 11 is driven to rotate through the worm 10, thereby driving the rotating shaft 3 and the adjusting seat 4 to rotate, so as to facilitate the flipping of the steel plate after welding the top surface, so as to weld the bottom surface of the steel plate. In some embodiments, the deflection of the adjusting seat 4 can also be achieved by gear meshing rotation, specifically, a driven gear is installed on the rotating shaft, and a driven gear is installed on the driven gear. The outer side of the moving gear is meshed with the driving gear, and the deflection of the adjustment seat 4 is achieved by the rotation of the driving gear and the driven gear. However, the rotation of the gear cannot be locked, and the steel plate cannot be effectively fixed in the current position when the steel plate is welded, which easily causes the steel plate to deflect. The worm 10 and the worm wheel 11 can be used to lock the position of the rotating shaft 3 and the adjustment seat 4 after flipping. According to the layout of the steel plate in this application, when the adjustment seat 4 is flipped 90 degrees, the welded steel plate will face outward, which is convenient for unloading the steel plate, further enhancing the practicality of the device.

[0044] According to the technical solution of the present application, a guide block 17 is fixedly connected to the side wall of the welding machine 13, and a guide groove 18 compatible with the guide block 17 is opened on the side wall of the cross bar 12. By using the set guide block 17 and guide groove 18, the welding machine 13 can be installed on the cross bar 12 to prevent it from detaching, and a handle is installed on the side wall of the welding machine 13. When welding is required, the staff holds the handle and pushes the welding machine 13 to move on the cross bar 12, which is convenient for straight seam welding of steel plates without the need for alignment.

[0045] Specifically, when it is necessary to weld the plates of the power tower, first place the plates on the mobile frame 6, then turn the second handle 15 to drive the fixed plate 8 to move downward to clamp and fix the plates. After the two plates are fixed, turn the first handle 14 to drive the first threaded rod 5 to rotate, so that it drives the two mobile frames 6 to move toward the middle at the same time, and splice the two fixed steel plates together. At this time, the splicing seam of the two plates will be located below the welding machine 13. Then the staff holds the handle and starts the welding machine 13 to perform straight seam welding on the steel plates. After the top welding is completed, turn the third handle 16 to drive the worm 10 to rotate, and drive the worm wheel 11 to rotate through the worm 10, thereby driving the rotating shaft 3 to rotate. When the rotating shaft 3 rotates, it will drive the adjusting seat 4 to flip, so that the plate can be flipped, which is convenient for welding the bottom surface after the top surface welding is completed. There is no need to disassemble and re-fix the plate, which is convenient and practical. It should be noted that there is a certain damping between the rotating shaft 3 and the support seat 2, so when the steel plate is flipped, no deflection or shaking will occur, affecting the welding effect.

[0046] The welding device for producing power poles and towers provided by the present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0050] The cross bar 12 is fixed on the support seat 2, and a welding machine 13 is slidably connected inside the cross bar 12.

[0051] The working principle and use process of the utility model are as follows: first, the plate is placed on the movable frame 6, and then the second turning handle 15 is turned to drive the fixed plate 8 to move downward to clamp and fix the plate. After the two plates are fixed, the first turning handle 14 is turned to drive the first threaded rod 5 to rotate, so that it drives the two movable frames 6 to move toward the middle at the same time, and the two fixed steel plates are spliced ​​together. At this time, the splicing seam of the two plates will be located below the welding machine 13. Then the staff holds the handle and starts the welding machine 13 to perform straight seam welding on the steel plate. When the top welding is completed, the third turning handle 16 is turned to drive the worm 10 to rotate, and the worm wheel 11 is driven to rotate through the worm 10, thereby driving the rotating shaft 3 to rotate.
