Anchor bolt embedded welding auxiliary device

Abstract

The invention discloses a foundation bolt pre-burying auxiliary welding device, and belongs to the technical field of electric auxiliary tools. The foundation bolt pre-burying auxiliary welding device comprises a bottom plate, a positioning sleeve, a sliding block and a locking part, wherein sliding grooves are formed in the bottom plate radially by taking the central point of the bottom plate as a circle center; central included angles in a length direction among adjacent sliding grooves are equal; scales corresponding to lengths of the sliding grooves are formed in one side in the length direction of the sliding grooves in the bottom plate; a positioning hole is formed in the axial direction of the positioning sleeve; an opening is formed in one end of the positioning sleeve; the end, where the opening is formed, of the positioning sleeve serves as an open end; the bottom wall of the positioning hole serves as a positioning surface; the open end penetrates through the sliding grooves in the bottom plate and is then connected with the sliding block; a positioning boss is arranged, or a clamping plate is connected, onto the outer wall, adjacent to the open end, of the positioning sleeve; a connecting hole matched with the open end is formed in the sliding block; a locking hole matched with the locking part is formed in the sliding block; a calibration device is arranged on the sliding block. By adopting the foundation bolt pre-burying auxiliary welding device, a foundation bolt can be welded by only one person, the working efficiency is high, and the welding quality is good.

Description

technical field [0001] The invention relates to the technical field of electric power auxiliary appliances, in particular to an auxiliary device for pre-embedded welding of anchor bolts. Background technique [0002] With the development of power systems and the advancement of power construction technology, direct-buried cement poles have been gradually eliminated, and pre-buried bolt equipment foundations have been adopted by more and more substations. When the pre-embedded anchor bolt technology is used for construction, it is necessary to weld and fix the anchor bolts at various places with steel bars in advance to make multiple anchor bolts a whole. [0003] If the welding height of the steel bars welded on the anchor bolts is too high, it will cause cracks or bulges on the pouring surface formed after the foundation is poured. Bolts cannot be used. Therefore, the welding quality of anchor bolts is very important. [0004] Because there is no auxiliary device in the e...

Problems solved by technology

Since there is no objective judgment basis, the operator in the existing welding process can only adjust according to his personal feeling, and it is difficult to effectively guarantee the overall verticality of the anchor bolts after welding, the coplanarity of each vertex, and the welding quality

[0005] The center distance of the anchor bolts in the anchor bolt group completed by the existing welding method may not meet the design requirements. If the center distance of two anchor bolts is greater than 1cm, it is necessary to blow off the reinforcement bars and the anchor bolts. The welding points of the bolts are then re-welded, the working hours are long, the work efficiency is low, and the quality of the anchor bolts after welding is seriously affected

[0006] In addition, in the same group of anchor bolts completed by the existing welding method, the exposed thread lengths of the anchor bolts are uneven, and the tops of the anchor bolts are not likely to be on the same plane.

When the tops of the anchor bolts differ by a certain distance, it is necessary to blow off the welding points of the steel bar and the anchor bolts and then re-weld. The workload of rework is large, the work efficiency is low, and the quality of the anchor bolts after welding is seriously affected.
