The utility model relates to a fixed mould of pipeline weld bond butt joint has solved easy dislocation in the small pipe diameter pipeline weld bond butt joint process, and constructor can't find suitable operating position and take time and trouble scheduling problem when independent uses such as current fixed pipe clamp, checkpost, clip. The utility model discloses the mould includes the support frame, and the top of support frame is fixed with to mouthful groove, is fixed with operation platform to mouthful groove on, center pin, connecting axle and the location axle that connects gradually on the operation platform, and the location axle is located directly over to mouthful groove. The utility model discloses fixed mould design science, simple structure, preparation are easy, easy and simple to handle, low cost, circulated used repeatedly, can fixed pipeline, prevent the dislocation in the butt joint in-process, avoided the drawback that causes the weld joint dislocation because of the difficult fixed in the butt joint both ends of pipeline before the welding, the effectual recruitment quantity of having practiced thrift has shortened operating time, very big improvement the efficiency of construction.
Description
Technical Field
The utility model relates to a pipeline weld bond butt joint technical field, in particular to an auxiliary fixture that is used for prefabricated small-diameter pipeline weld bond butt joint in the limited operation space specifically is a fixed mould of pipeline weld bond butt joint.
Background
At present, the known auxiliary fixing devices for the butt joint of the weld joints of the small-diameter pipelines are provided with fixed pipe clamps, clips, clamps and the like, and the auxiliary fixing devices are used for fixing the pipelines before spot welding during butt welding of the pipelines so as to prevent the pipelines from dislocation and shaking. However, the existing fixing pipe clamps, clips, clamps and the like are easy to fall off in the fixing process, and in the installation process, a constructor cannot find a proper operation position, and the operation position belongs to a normal state, so that the part of the fixing pipe clamps, clips, clamps and the like is used by other aids, and a used single piece is small and easy to lose, the construction complexity is increased, the manual waste is caused, and the work efficiency is reduced.
Disclosure of Invention
The utility model aims at solving the easy dislocation of small pipe diameter (being less than DN100) pipeline weld bond butt joint in-process, and constructor can not find suitable operating position and take time and work a lot of scheduling problem when independent uses such as current fixed pipe clamp, checkpost, clip, and provide a fixed mould of pipeline weld bond butt joint.
The utility model discloses a realize through following technical scheme:
a fixing die for butt joint of pipeline welded junctions comprises a support frame, wherein a long-strip butt joint groove with an upward notch is fixed at the top of the support frame; an operation platform which is horizontally arranged is fixed at the groove edge at one side of the top of the butt groove; a fixing nut is fixed on the operating platform, a vertically arranged central shaft is connected to the fixing nut, a horizontally arranged connecting shaft is connected to the central shaft, a vertically arranged positioning shaft is connected to the far end of the connecting shaft, and the central shaft and the connecting shaft as well as the positioning shaft and the connecting shaft are in threaded connection; the top end of the positioning shaft is fixed with a rotating handle, and the axis of the positioning shaft is superposed with the center line of the notch of the aligning groove.
During construction, will the utility model discloses fixed mould places in the intensive prefabricated aspect of pipeline needs, then places the pipeline in fixed mould's the opposite port inslot. Before the pipelines are aligned, the rotating handle can be pulled, and the positioning shaft is pushed to the alignment surface of the alignment groove; when the pipeline is aligned, the rotating handle is pulled, the positioning shaft is pulled back to the position above the pipeline, the double shafts (the positioning shaft and the central shaft) are controlled to position the aligned pipeline by rotating the rotating handle, namely the positioning shaft is pushed to a specified position by screwing the rotating handle and is fixed at the top end of the aligned pipeline; after the pipeline is aligned, the positioning shaft is loosened through rotating the rotary handle, the rotary handle is stirred, the positioning shaft is pushed to the alignment groove alignment surface, and the alignment pipe is convenient to remove and install. In the specific butt joint process, along with the size of pipe diameter, the height and the position of location axle can be adjusted to the accessible rotation handle.
As the preferred technical scheme, the support frame is a lifting support frame. The support frame can go up and down as required to satisfy the constructor of different statures physique, thereby reach the state work of relative freedom.
The utility model discloses fixed mould design science, simple structure, preparation are easy, easy and simple to handle, low cost can fixed pipeline, prevent the dislocation in the butt joint in-process, have avoidd the drawback that causes the weld joint dislocation because of the difficult fixed in the butt joint both ends of pipeline before the welding, and the effectual recruitment quantity of having practiced thrift has shortened operating time, very big improvement the efficiency of construction. And the utility model discloses the mould is releasable connection, circulated used repeatedly, has higher practical value.
