During the installation of the piers, the position and height of the piers are first determined, and then the foundation construction is carried out. Next, the columns and beams of the piers are installed, and finally welding and tightening work is carried out. During the welding process of the viaduct piers, as the welding height of the columns changes, the center of gravity of the lifting equipment rises. At this time, the stability of the lifting equipment is poor, which may affect the welding accuracy and safety of the welding operation. In addition, the harmful gases and smoke generated during welding may affect the operators or the surrounding environment.

The part body can be clamped between the two clamping assemblies. A spacing adjustment assembly used in conjunction with the two clamping assemblies is also provided in the working box.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. An adjustment component is provided. When welding the column and beam at a high place, the operator climbs to the top of the support plate using a ladder. At this time, multiple hydraulic lifting rods are started. The telescopic end of the hydraulic lifting rod drives the support plate and the enclosure to rise, and the telescopic end of the hydraulic lifting rod also drives the arc block and the toothed plate to rise. The toothed plate first meshes with the lowest gear, and when the toothed plate is from contact with the gear to separation from the gear, it will just drive the gear to rotate half a circle.

When the limit When the rod is stuck in the lower seat, the inner rod drives the plug connector to be completely stuck in the slot, thereby improving the connection strength between the hydraulic lifting rod and the fixed column and the supporting stability of the support plate. When the hydraulic lifting rod drives the arc block to descend, the toothed plate drives the gear to reverse and reset, the limit rod is stuck in the upper seat, the pull rope is wound and reeled in, and the pull rope drives the plug connector to reset. The multiple gears set will be driven in sequence as the height of the arc block rises, so that the plug connector is clamped in the slot from bottom to top in sequence, so that the lifting height of the support plate can be adapted to the lifting height, and the supporting stability can be superimposed in sequence, reducing the problem of increasing the center of gravity during lifting and affecting the supporting stability, and solving the problem of not being convenient to correspondingly improve the stability of the lifting equipment when welding high-place columns and beam components, reducing the welding accuracy and welding safety of operators;

[0031] 2. A positioning assembly is provided. After adjusting the height, the operator starts the electric push rod, which drives the clamping block to press against the column body, so as to facilitate the positioning of the column body. Then, the cross beam body is kept between the two positioning bars on the same side, and the double-headed screw on the side is rotated. The limit frame limits the positioning bar, so that the two positioning bars are close to each other until the two positioning bars clamp the cross beam body, so as to facilitate the horizontal positioning welding of the cross beam body, and improve the welding stability. When the operator uses the welding equipment to weld, the exhaust fan is started, and the exhaust fan exhausts air through the extraction pipe and the extraction hood, so as to facilitate the extraction of the fume and dust generated by welding, and temporarily store them in the dust collecting box, so as to improve the convenience of welding.
