Description

Technical Field

[0001] The invention relates to the technical field of center tie beam welding, and more specifically, to a center tie beam welding device and a construction method for a bridge pier. Background Art

[0002] In the current construction field, especially in the installation of center tie beams, the welding process is a key link to ensure structural stability and safety. During the welding process after the installation of the center tie beams, some complex corners are often encountered. Due to space limitations and special angles, these areas cannot be welded with automatic welding equipment, and must rely on construction workers to use handheld electric welding tongs for manual welding. However, the existing electric welding tongs have many shortcomings in design. The connection method between them and the wires is relatively traditional, and the disassembly and assembly process is cumbersome. Frequent replacement of welding rods or adjustment of positions at the construction site often requires a lot of time and effort.

[0003] In addition, another significant problem exhibited by existing electric welding tongs during actual use is the limitation of electrode position adjustment. Since the structural design of the electric welding tongs is not user-friendly enough, it is difficult for operators to quickly and accurately adjust the angle and direction of the electrode according to different welding angles and position requirements. This design deficiency not only reduces construction efficiency, but may also affect welding quality, especially in some key structural parts that require fine welding. It is difficult for operators to maintain a stable welding posture, which can easily cause problems such as uneven welding or insufficient welding strength. Summary of the invention

[0013] The present invention provides a welding construction method for a center tie beam for a bridge pier, comprising the following steps: Step 1 Angle adjustment process: The operator first pulls the middle disk to drive the adjustment sleeve to slide downward to disconnect it from the adjustment slot, and then rotates the middle disk. Due to the sliding connection between the adjustment sleeve and the inner rod, the inner rod is driven to rotate, so that the rotating circle and the double-side seats are rotated to the required angle. After releasing the middle disk, the adjustment sleeve is reinserted into the adjustment slot under the action of the push spring to achieve fixed locking of the angle; Step 2: Welding rod installation process: The operator holds the guide rod and the handle with one hand, pulls the handle upward to move the pressure block upward, at which time the compression spring is compressed, and inserts the welding rod into the conductive sleeve with the other hand.

Two guide rods 211 are respectively installed on the two double-side seats 24, and a pressure block 212 is slidably connected to each of the two guide rods 211, and a handle 213 is respectively installed on each pressure block 212. A compression spring 214 is sleeved on each guide rod 211, and the compression spring 214 contacts the pressure block 212. A positioning rod 215 is coaxially installed on the inner rod 26, and the positioning rod 215 is rotatably connected in the receiving disk 12. A conductive rod 216 is installed in the fixed sleeve 11, and the conductive rod 216 is electrically connected to the two conductive sheets 22. The rotating circle 21 and the double-side seats 24 are both insulating plastics. The middle circle 23 is embedded in the two conductive sheets 22, and the positions that the operator can touch are all insulated.

[0021] When the operator is welding at the corners of the centering beam, since the welding angle needs to be adjusted according to different situations, the operator first pulls the middle disk 29, which will then drive the adjusting sleeve 27 to slide downward, so that the adjusting sleeve 27 will untie the connection with the adjusting slot 28, and then rotate the middle disk 29. Since the adjusting sleeve 27 is slidably connected to the inner rod 26, it will drive the inner rod 26 to rotate accordingly, and then the rotating circle 21 and the double side seats 24 will rotate accordingly, and then adjust them to the corresponding positions, and then release the middle disk 29. Under the action of the push spring 210, the adjusting sleeve 27 is inserted into the adjusting slot 28 at the corresponding angle, and the fixing stability of the double side seats 24 is guaranteed by the action of the push spring 210, so its angle can be adjusted, ensuring the stability of the angle adjustment.

[0022] When it is necessary to fix the welding rod, the operator first holds the rod and handle 213 at the upper end of the guide rod 211 with one hand, and then pulls the handle 213 hard to make the pressure block 212 move upward. At this time, the pressure block 212 slides upward along the guide rod 211 and the compression spring 214 is in a compressed state. The other hand inserts the welding rod into the corresponding conductive sleeve 25, and then releases the hand to apply pressure to the pressure block 212 under the action of the compression spring 214, and makes the welding rod stuck between the conductive sleeve 25 and the pressure block 212. Since the conductive sleeve 25 is electrically connected to the middle ring 23, and the conductive sheet 22 is electrically connected to the middle ring 23 and the conductive rod 216, the welding rod is electrically connected to the conductive rod 216, and the conductive rod 216 is electrically connected to the cable of the welding machine through the insertion sleeve 310, so the corresponding welding process can be carried out, thereby improving the convenience of use.

[0023] See also Figures 3 to 8 The connection mechanism includes an outer sleeve 31 fixedly mounted on the fixed sleeve 11, and a plurality of clamping blocks 32 arranged at equal intervals along the axis are provided in the outer sleeve 31, a wrapping sleeve 33 is rotatably mounted on the outer sleeve 31, and a threaded strip 34 is installed in the wrapping sleeve 33, and a plurality of clamping blocks 32 are attached to the inner wall of the wrapping sleeve 33, and a threaded groove 35 is provided on a side of each clamping block 32 close to the wrapping sleeve 33, and the threaded groove 35 is engaged with the threaded strip 34, an inclined groove 101 is provided in the outer sleeve 31, and the clamping block 32 is slidably connected in the inclined groove 101, and the connection mechanism also includes an embedded groove 36 provided on the outer sleeve 31, and the inner An inner ring 37 is slidably connected in the embedded groove 36, a manual sleeve 38 is installed on the inner ring 37, and the manual sleeve 38 is connected to the wrapping sleeve 33, and a hexagonal sleeve 39 is installed on the manual sleeve 38, an insertion sleeve 310 is slidably connected in the outer sleeve 31, and the insertion sleeve 310 is connected to the cable of the welding machine, and an internal hole 311 is provided on the insertion sleeve 310, and the conductive rod 216 is electrically connected in the internal hole 311, and each clamping block 32 is installed with a fitting block 312 on one side close to the axis, and each fitting block 312 is respectively provided with a plurality of anti-slip grooves 313, and a plurality of groups of anti-slip grooves 313 are respectively fitted on the side walls of the insertion sleeve 310.

[0024] When the conductive rod 216 and the cable need to be electrically connected, the insertion sleeve 310 on the cable is first inserted into the outer sleeve 31. At this time, the diameter between the multiple fitting blocks 312 is larger than the diameter of the insertion sleeve 310, so the internal hole 311 on the insertion sleeve 310 can be electrically connected to the conductive rod 216, so that the conductive rod 216 is tightly inserted into the internal hole 311, and then the manual sleeve 38 is rotated. Since the inner ring 37 in the manual sleeve 38 is embedded in the inner groove 36, the manual sleeve 38 and the outer sleeve 31 can only rotate relative to each other, and the other end of the manual sleeve 38 is sleeved on the outer sleeve 31, and the multiple threaded strips 34 are engaged in the threaded groove 36. 5, as the manual sleeve 38 rotates, the thread groove 35 rotates, and then the clamping block 32 moves along the inclined groove 101 toward the embedded groove 36 and is in a contracted state until the anti-slip groove 313 on the fitting block 312 presses on the side wall of the insertion sleeve 310, thereby applying a clamping force and a force to move toward the conductive rod 216, which not only ensures the fixed stability of the insertion sleeve 310 but also ensures the stability of the connection between the conductive rod 216 and the internal hole 311, so that it can be easily assembled, and the convenience of use of both is ensured by the convenient assembly, and the heavy cable is prevented from affecting the use of the operator.
