In petrochemical plant pipeline installation construction, a welding process has become a mainstream of steel pipeline installation, and pipeline weld joint pairing is the most critical process in pipeline welding operation, and the speed and the quality of the pairing directly relate to weld joint quality and welding efficiency. In the field practical pairing operation process, the problems that the ovality of the pipeline exceeds the standard, the wall thickness of the pipeline has errors, the pairing clamp cannot be fixed and the like are often faced, and the pairing quality and efficiency are seriously influenced. How to quickly finish the pipeline weld pairing operation with high quality without damaging the parent metal is a problem which is always explored by countless pipeline constructors.
At present, in the welding seam assembly installation construction of process pipelines, the following difficulties are mainly faced: in actual construction, the most common and common method of welding seam assembly of the process pipeline is that a pipeline is used as a reference, welding seam assembly clamping tools and adjusting tools are uniformly distributed on the outer wall of the pipeline, levelness, misalignment amount and the like of the pipeline connected with the welding seam assembly clamping tools are adjusted, and finally welding seam assembly operation is completed. The method can realize the purpose of weld joint assembly, but the temporary assembly tooling or clamping apparatus is required to be welded on the pipeline, so that the damage of the parent metal of the pipeline is caused, the tooling or clamping apparatus is required to be cut off and polished after welding, the unnecessary engineering quantity is increased, the efficiency is low, and the cost is high.
Disclosure of Invention
The utility model aims to solve the technical problems in the prior art and provides a portable pipeline weld joint assembling clamp, which can rapidly complete pipeline weld joint assembling under the condition of not damaging parent metal, and has high efficiency and low cost.
The utility model aims to solve the technical problems in the prior art, and adopts the technical scheme that: a portable pipeline weld joint assembly fixture adopts a hoop structure, is formed by connecting a front semicircular tube plate and a rear semicircular tube plate in a butt joint way, wherein one side of the front semicircular tube plate and one side of the rear semicircular tube plate are hinged, and the other side of the front semicircular tube plate and the rear semicircular tube plate are locked with two mounting lugs by bolts and nuts; one end of each of the front semicircular tube plate and the rear semicircular tube plate adopts a tooth groove structure, and is provided with clamping teeth and tooth grooves, wherein the number and the positions of the tooth grooves are matched with those of the welding spots in the group.
The two mounting lugs are provided with caulking grooves at the lower part of one of the mounting lugs, the butt joint surface of the other mounting lug is provided with the bolt hinged with the mounting lug, and the bolt is embedded into the caulking grooves during locking.
The nut is a butterfly nut.
The length of the latch is 35 mm-40 mm.
The utility model has the advantages and positive effects that: by adopting the hoop structure, the damage to the parent metal can be avoided; the structure that one side is hinged, and the other side is locked with the two mounting lugs by the bolts and the nuts is adopted, so that the offset can be eliminated by opening and closing one by one, the operation is simple, and the efficiency is high; by adopting the tooth groove structure, the number and the positions of the tooth grooves are matched with those of the welding spots in the assembly, and the spot welding is implemented in the tooth grooves in the assembly, so that the operation is simple, the efficiency is high and the quality is good. In conclusion, the method is simple to operate, high in efficiency, free of damaging the parent metal and capable of reducing construction cost. The utility model has simple and portable structure, can be repeatedly used and has low cost; the device is suitable for the assembly between pipelines, can also be suitable for the assembly of pipelines and pipe fittings, and has wide application range.
