Description

Technical Field

[0001] This utility model relates to the field of power tower welding technology, specifically a welding device for iron accessories of power towers. Background Technology

[0002] Power transmission towers are tower-shaped structures used for power transmission. Their structural characteristics are that all tower types are spatial truss structures, and the members are mainly composed of single equilateral angle steel or combined angle steel. The materials generally used are Q235 and Q345. Steel pipes are required in the iron accessories used in power transmission towers. Traditionally, flanges are welded to both ends of the steel pipes during use to facilitate the connection and installation of the steel pipes with other workpieces.

[0003] According to the existing patents disclosed on the China Patent Network (Announcement No.: CN 219881638 U), the two welding heads are fixed by clamping mechanism and adjusted to the appropriate positions at both ends of the steel pipe by horizontal adjustment mechanism. Then the motor is started, which makes the drum rotate. That is, the steel pipe rotates to achieve simultaneous welding of the flanges at both ends, thus improving welding efficiency.

[0004] However, the above technical solutions still have certain defects. Since the steel pipe to be welded has a certain length, the steel pipe will tilt and swing left and right if it is only supported by the vertical plate. However, when welding the steel pipe and the flange, manual assistance is required to align the flange and the end of the steel pipe, resulting in low welding efficiency. Therefore, a welding device for iron accessories of power tower is proposed. Utility Model Content

[0007] The bottom of the positioning plate frame is connected to a T-plate, which is slidably disposed on the top of the base plate and extends beyond the end face. The top of the base plate is provided with a clearance groove for the T-plate to slide. A driven plate is rotatably sleeved inside the positioning plate frame. An inner plate is fixed at one end of the driven plate near the rolling assembly.

[0008] As a preferred technical solution, the bottom of the positioning plate frame is fixed to the top of the T plate with bolts, and the top of the T plate has multiple sets of threaded holes at equal intervals.

[0009] As a preferred technical solution, the end of the driven disk near the rolling assembly is in the shape of a blind hole, and the blind hole, the inner disk, and the sealing rod form a flange groove for storage.

[0010] As a preferred technical solution, dovetail strips are fixed on the front and rear sides of the T-plate, and dovetail grooves are formed on the inner wall of the clearance groove at positions corresponding to the dovetail strips.

[0011] As a preferred technical solution, the rolling assembly includes a base fixed to the top of the base plate. The top of the base is connected to a movable seat by a hinge. The curved inner wall of the base is rotatably provided with multiple sets of drive rollers that drive the steel pipe to rotate. One end of one of the drive rollers extends to the outside and is equipped with a first transmission gear. A drive motor is assembled on one side of the end of the base. The output end of the drive motor is equipped with a second transmission gear that drives the first transmission gear to rotate.

[0012] As a preferred technical solution, the welding component includes an L-arm fixed to the top of the base plate and extending above the rolling assembly.

[0014] In summary, the present invention has the following main advantages:

[0015] This invention uses a positioning frame to position the flange welded to the end of the steel pipe, simplifying the manual welding process. It also protects the flange end face and threaded hole, preventing weld slag from adhering and affecting subsequent splicing.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The embodiments of this utility model will be described below based on its overall structure.

[0024] A welding device for iron accessories of power transmission towers, such as Figures 1 to 5 As shown, it includes a base plate 100, a rolling assembly 110 for clamping steel pipes is mounted on the top of the base plate 100 and in the center position, a positioning plate frame 120 with positioning flanges is provided on both sides of the top of the base plate 100 and a welding component 130 fixed to the top of the base plate 100 is provided behind the rolling assembly 110.

[0025] The bottom of the positioning plate frame 120 is connected to a T-plate 140. The T-plate 140 is slidably disposed on the top of the base plate 100 and extends to the outside of the end face. The top of the base plate 100 is provided with a clearance groove 150 for the T-plate 140 to slide. The inside of the positioning plate frame 120 is rotatably sleeved with a driven plate 121. An inner plate 123 is fixed at one end of the driven plate 121 near the rolling assembly 110. Multiple sets of sealing rods 122 are fixed in a ring array on the outer side of the inner plate 123 inside the driven plate 121.

[0026] The driven plate 121 is blind hole-shaped at the end near the rolling assembly 110, and the blind hole, the inner plate 123 and the sealing rod 122 form a storage flange groove;

[0027] The rolling assembly 110 includes a base 111 fixed to the top of the base plate 100, and a movable seat 112 is connected to the top of the base 111 by a hinge.

[0028] During welding, the two sets of T-plates 140 are pulled and slid horizontally along the relief groove 150, causing the two sets of positioning plate frames 120 to gradually move away from the rolling assembly 110. The movable seat 112 can then be opened and rotated around its connection point with the base 111, allowing the steel pipe to be placed inside the base 111. At this point, the movable seat 112 is reversed and restored to its original position, wrapping around the outer wall of the steel pipe, thus completing the positioning of the steel pipe. Next, the flange is placed in the flange groove, at which point multiple sealing rods 122 will enter the flange's pre-drilled groove. Inside the threaded hole, the flange will be fitted onto the outer wall of the inner plate 123 to protect the threaded hole on the flange, which can prevent weld adhesion from affecting subsequent use and ensure that the end face of the flange away from the steel pipe is in a flat state, ensuring that the end faces of the flanges at the joint of the two sets of steel pipes can fit tightly. As the two sets of T plates 140 can be pushed closer to the rolling assembly 110, the positioning plate frame 120 moves synchronously, and the flange in the flange groove contacts the end of the steel pipe. At this time, the welding operation of the steel pipe and the flange can be performed.

[0029] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The bottom of the positioning plate frame 120 is fixed to the top of the T plate 140 with bolts, and multiple sets of threaded holes are equally spaced on the top of the T plate 140.

[0030] The position of the positioning plate 120 fixed on the top of the T plate 140 can be determined according to the length of the steel pipe to be welded. This allows for the positioning of the flanges at both ends, thereby improving the welding efficiency between the flanges and the ends of the steel pipe.

[0031] Please refer to this carefully. Figure 2 and Figure 5 The front and rear sides of the T plate 140 are fixed with dovetail strips 141, and the inner wall of the clearance groove 150 is provided with dovetail grooves 151 at the corresponding positions of the dovetail strips 141.

[0032] By using dovetail strip 141 and dovetail groove 151 to increase the static friction coefficient between them, it is ensured that T plate 140 will not move arbitrarily, and the positioning plate frame 120 can make the flange contact the end of the steel pipe and perform welding work.

[0033] Please refer to this carefully. Figure 1 and Figure 3 The welding component 130 includes an L-arm 131 fixed to the top of the base plate 100 and extending above the rolling assembly 110. The end of the L-arm 131 is located above the rolling assembly 110 and the two sets of positioning plate frames 120. Two sets of positioning sleeves 133 are slidably fitted on the outer wall of the frame beam 132. A welding head 135 for welding flanges and steel pipes is assembled below each set of positioning sleeves 133. An electric telescopic rod 134 for driving the welding head 135 to rise and fall is assembled at the bottom of the positioning sleeve 133.

[0034] The front surface of the positioning sleeve 133 has a locking bolt that rotatably abuts against the front surface of the frame beam 132. The front surface of the positioning sleeve 133 has an internal thread hole that matches the locking bolt. The telescopic end of the electric telescopic rod 134 is equipped with a connecting seat at the contact position with the welding head 135, and the connecting seat is rotatably connected to the outer wall of the welding head 135 by a damping shaft.

[0035] The curved inner wall of the base 111 is provided with multiple sets of drive rollers 113 that drive the steel pipe to rotate. One end of one type of drive roller 113 extends to the outside and is equipped with a first transmission gear. A drive motor 114 is assembled on one side of the end of the base 111. A second transmission gear that drives the first transmission gear to rotate is installed at the output end of the drive motor 114.

[0036] The locking bolt can be manually rotated to loosen it, and the positioning sleeve 133 can be pushed to slide on the outer wall of the frame beam 132. The electric telescopic rod 134 can be operated to lower the welding head 135 and bring it closer to the steel pipe, so that the welding head 135 is in the contact position between the steel pipe and the flange. At this time, the locking bolt can be rotated so that its end touches the frame beam 132, and the welding head 135 can be controlled to perform welding operations. At the same time, the drive motor 114 outputs work, which will drive the second transmission gear to rotate. The first transmission gear will also rotate synchronously and drive the drive roller 113 to rotate. Finally, the steel pipe can be driven to rotate, thus completing the full welding operation of the flange at the end of the steel pipe.

[0037] In use, the two sets of T-plates 140 need to be pulled and slid horizontally along the clearance groove 150, so that the two sets of positioning plate frames 120 gradually move away from the rolling assembly 110. The movable seat 112 can be opened and rotated around the connection point with the base 111. The steel pipe is then placed inside the base 111. At this time, the movable seat 112 is turned back to its original position and wrapped around the outer wall of the steel pipe, thus completing the positioning of the steel pipe. Next, the flange is placed in the flange groove. At this time, multiple sealing rods 122 will enter the threaded holes reserved in the flange, and the flange will be fitted onto the inner plate 123. The outer wall protects the threaded holes on the flange, preventing weld adhesion from affecting subsequent use and ensuring that the flange end face away from the steel pipe is flat. It also ensures that the flange end faces at the joint of the two sets of steel pipes can fit tightly together. As the two sets of T plates 140 are pushed closer to the rolling assembly 110, the positioning plate frame 120 moves synchronously, and the flange in the flange groove contacts the end of the steel pipe. At this time, welding operations can be performed on the steel pipe and the flange. All parts not involved in this device are the same as or can be implemented using existing technology.
