Description

Technical Field

[0001] The utility model belongs to the technical field of steel-in-steel production equipment, in particular to a steel-in-steel cutting and welding compensating elbow. Background Art

[0002] Steel-in-steel is one of the most common steel products at this stage. It needs to go through a welding process during the production process. In order to improve the welding quality during the steel-in-steel welding process, it is also necessary to perform welding compensation. When performing welding compensation, it is necessary to use a welding compensator. The welding compensator used for steel-in-steel welding is mostly a tubular structure, which is inserted inside the steel-in-steel. It is not only used to bear the steel-in-steel, but also used to assist the two steel-in-steel that need to be welded to each other to dock.

[0003] The existing welding compensator used for steel-in-steel welding is a tubular object, which can be hollow or solid, and is connected to each other in a vertical welding manner. Therefore, when welding the steel-in-steel, two steel-in-steel sleeves need to be inserted at both ends of the tubular compensator;

[0004] The above-mentioned welding compensator used for steel-in-steel welding is a tubular structure. When in use, the steel sleeve needs to be inserted into it. The calibers of different types of steel sleeves are also different. When the steel sleeve is inserted into it, it cannot be perfectly matched, and it is easy for the steel sleeve to shake or rotate on its surface. Also, when the steel sleeve is inserted into the tubular welding compensator, the welding work at the butt joint can be carried out. As the welding work continues, the position of the weld needs to be adjusted to facilitate welding. However, the method of adjusting the weld is to hold the steel sleeve pipe by hand to rotate it on the tubular welding compensator, which is not only extremely physically demanding but also easy to cause the weld to deviate from the initial position. To this end, we provide a steel sleeve cut welding compensation elbow to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a steel-in-steel cut-welding compensating elbow, which can fix steel-in-steel with different diameters on the outer wall of a straight pipe by utilizing a supporting assembly, and because the supporting assembly is installed on a driving assembly, the supporting assembly can be driven to rotate by the driving assembly, thereby achieving the effect of rotating the steel-in-steel, thereby solving the problems of the existing welding compensator used for steel-in-steel welding.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a steel sleeve steel cut-welding compensation elbow, comprising a straight pipe and a bent pipe rotatably connecting two straight pipes; a pipe groove is provided inside the straight pipe, a driving assembly is clamped in the pipe groove, the driving assembly comprises a stepping motor and a rotating rod installed on the shaft end thereof, a fixing frame is respectively provided on the stepping motor and the rotating rod, and the fixing frame is clamped at both ends of the pipe groove;

[0008] A support assembly is arranged on the outer wall of the rotating rod, and the support assembly comprises a central column and a hydraulic rod installed on the outer side wall thereof, and a support plate is installed on the shaft end of the hydraulic rod.

[0009] The utility model is further configured that the inner walls of the two axial ends of the pipe groove of the straight pipe are provided with clamping grooves, and the clamping grooves are clamped with the end side walls of the fixing frame, and the fixing frame is arranged in a "cross" shape.

[0010] The utility model is further configured such that the support legs of the stepper motor in the driving assembly are connected to the fixing frame by bolts, and the stepper motor is connected to the slot at the end of the pipe slot shaft through the fixing frame, a bearing is embedded on the inner wall of the other fixing frame, and the fixing frame is rotatably connected to the rotating rod through the bearing.

[0011] The utility model is further configured that side holes are opened on the outer wall of the straight tube, and the side holes are provided in three groups, each of which has four side holes, and one group of side holes is correspondingly provided to one support assembly.

[0012] The utility model is further configured such that a connecting sleeve is embedded in the center of the central column in the support assembly, and the central column is fixedly connected to the rotating rod through the connecting sleeve. A column hole is opened on the outer wall of the central column, and there are four column holes in total, and the four column holes are respectively arranged at four quadrant points of the outer side wall of the central column.

[0013] The utility model is further configured that the column hole is threadedly connected to the connecting frame, and the central column is connected to the hydraulic rod through the connecting frame, the shaft end of the hydraulic rod is sleeved with a column sleeve, and the hydraulic rod is connected to the support plate through the column sleeve.

[0014] The utility model is further configured such that the support plate is configured in a triangular plate-like structure, and the rear side wall of the support plate cooperates with the inner wall of the side hole on the straight tube, a plate groove is opened on the outer side wall of the support plate, and an anti-slip pad is bonded in the plate groove.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model sets a support assembly. When the steel sleeve is connected to the outer wall of the straight pipe, the support assembly is started, and the hydraulic rod in the support assembly extends to drive the support plate on its shaft end to extend outward. At that time, the support plate will directly abut against the inner wall of the steel sleeve through the anti-slip pad, that is, the timely placement of steel sleeves of different calibers can also achieve a stable support effect.

[0017] 2. The utility model sets a driving component, and the supporting component is installed on the driving component. When the steel sleeve is fixed and the welding position needs to be adjusted, the driving component is started, and the stepper motor in the driving component works, and the rotating rod on the shaft end thereof also rotates accordingly. Then, because the supporting component is installed on the rotating rod on the driving component, the supporting component also rotates with the rotating rod. When the supporting component rotates, the steel sleeve abutted at its end can also rotate accordingly, thereby achieving the effect of adjusting the welding position.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
