Description

Pipeline welding is with device of keeping to mouthpart

Technical Field

The utility model belongs to the technical field of appurtenance for the pipe welding, especially, relate to a pipe welding is with device of keeping to needs of job.

Background

When the pipeline is buried underground, the pipe ditches (grooves) are orderly, the bottom of the ditches is tamped to be flat, the joint of the pipe orifices is internally sealed by adhesive tapes and is provided with a pipe support or a support pile, so that the pipeline is convenient to align and weld. Before installation, a welding surface (groove) and a welding pipe cavity are cleaned completely, and soil, oil stains and the like are not allowed to exist, so that the welding and sealing quality is guaranteed. The welding sequence is backing welding, filling welding and cover welding. The welding joint is required to be smooth and full, and welding slag, welding beading, splashes and other pollutants on the surface of a weldment are carefully cleaned after welding.

But at present when welding the pipeline, the pipeline is usually to the mouth through the manual work to the mouth department, and the butt joint department atress that can't accomplish each pipeline like this is unanimous, appears the leak source easily when leading to pipeline welding, needs the later stage to repair for rework labor cost is high, can cause the artifical waste of unnecessary.

SUMMERY OF THE UTILITY MODEL

The utility model has the advantages of reduce leak source quantity, reduce the rate of reprocessing of construction to practice thrift the cost of labor.

In order to solve the problems in the background art, the utility model discloses a realize through following technical scheme:

a butt joint device for pipeline welding comprises bases arranged on two sides of a pipeline, wherein a steel pipe is connected between the bases, and a force application assembly for applying force to a welding position is arranged on each steel pipe corresponding to each base; the force application assembly comprises hydraulic equipment and a fixing piece for clamping the pipeline; the fixing piece comprises a concentric clasping clamp; at least two groups of concentric clamps are arranged and are respectively positioned on the force application side of the hydraulic equipment; the elevation of the circle center of the concentric holding clamp is at the same elevation.

As a further explanation of the utility model: the base comprises I-steel.

Compared with the prior art, the utility model discloses following profitable technological effect has:

1. when preparing the welded tube, place this to mouthful device and do the support bottom the pipeline, the elevation that the department of pipeline was located can be guaranteed to the setting of pressing from both sides with one heart is unanimous, provide the power of horizontal direction by hydraulic equipment before the welding, the power of horizontal direction that has hydraulic equipment to provide this moment will be followed pipeline both sides and to the extrusion of pipeline welding department, with the assurance tight at the inside adhesive tape of welding process, thereby prevent that the leak source from appearing in the welding department, reach and reduce leak source quantity, reduce the repair rate of construction, practice thrift the purpose of cost of labor.

2. The base is the I-steel, because the rigidity of steel material is strong, so can suitably reduce the requirement to the degree of compaction of ditch groove bottom in the welding process to reduce by the tamping expense of machinery and manual work production.

3. Because the centre of a circle elevation of all embracing clamps is at same elevation, so this to mouthful device also can be used as the pipe aligning device, has practiced thrift equipment cost, and can replace present common pipeline welding to mouthful ware to realize the advantage of a tractor serves several purposes.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship which is usually placed when the product of the present invention is used, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

Furthermore, the terms "horizontal", "vertical" and the like do not imply that the components are required to be absolutely horizontal or pendant, but rather may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements.
