Background technology

In Modern Power Plant process of construction, in the workload of large footpath weld bond more and more, in the quality of large footpath weld bond and the counterpart quality of pipeline have very large care, meeting as bad in counterpart causes root mismatch, occurs incomplete fusion or root undercut; Cause two female tube-surfaces uneven simultaneously, all essential counterpart work of paying attention to Large diameters, how better efficiently pipe welding port to good, reach the requirement in standard.At present, during general Large diameter counterpart, take to use a plurality of electric blocks to regulate weld bond, determine the horizontal and vertical requirement of pipeline, not only need long time to regulate, also wasted a large amount of manpowers, material etc., sometimes also do not guarantee the welding quality of counterpart simultaneously.

Summary of the invention

The utility model is in order to overcome the deficiency of above technology, and a kind of pipeline welding counterpart adjusting device that can rapid adjustment pipeline alignment clearance is provided.

The utility model overcomes the technical scheme that its technical problem adopts:

This pipeline welding counterpart adjusting device, comprise semicircular in shape and internal diameter and need the pipeline I of butt welding and clasp I and clasp II that pipeline II external diameter matches, be arranged at respectively the fastener of clasp I and clasp II both sides, described clasp I and clasp II are fastened on the alignment clearance place of pipeline I and pipeline II, and clamp and be fixed on pipeline I and pipeline II outer surface by fastener, in described clasp I and clasp II, be along the circumferential direction provided with some slotted holes, the mouth of pipe gap between pipeline I and pipeline II is positioned at the below of slotted hole.

Above-mentioned fastener comprises the ear seat I and the ear seat II that are arranged at respectively clasp I and clasp II both sides, is fixed on the jack in ear seat I and is arranged at the hook groove in ear seat II, the upper end of link is connected in the piston rod head end of jack, and its lower end is placed in hook groove.

In order to realize accurate adjustment, also comprise and be along the circumferential direction fixed on the some nuts in clasp I and clasp II and be combined on bolt in each nut, the bottom of described each bolt contacts with the outer surface of pipeline I.

For the convenient size of adjusting mouth of pipe gap, also comprise and be along the circumferential direction arranged at the some circular holes in clasp I and clasp II and be plugged in each circular hole and head end is conical lash adjusting device, the head end of described lash adjusting device is arranged in mouth of pipe gap.

The beneficial effects of the utility model are: clasp I and clasp II are buckled in the pipeline I and pipeline II that needs welding, and lock by fastener, clasp I after locking and clasp II are that a circle is wrapped in pipeline I and pipeline II outer surface, thereby make the dead in line of pipeline I and pipeline II, therefore can not cause all well and good mouthful and the generation of rough phenomenon.During welding, welding rod is inserted from slotted hole, in mouth of pipe gap location welding portion length, to unclamp fastener afterwards, clasp I and clasp II are removed from pipeline I and pipeline II, the local repair welding of again mouth of pipe gap location not being welded is afterwards complete, can realize the butt welding work of pipeline, simple and fast, has improved efficiency.

The specific embodiment

Below in conjunction with accompanying drawing 1 to 4 pairs of the utility model of accompanying drawing, be described further.

As shown in Figures 1 and 2, this pipeline welding counterpart adjusting device, comprise semicircular in shape and internal diameter and need the pipeline I 8 of butt welding and clasp I 1 and the clasp II 2 that pipeline II 9 external diameters match, be arranged at respectively the fastener of clasp I 1 and clasp II 2 both sides, clasp I 1 and clasp II 2 are fastened on alignment clearance 10 places of pipeline I 8 and pipeline II 9, and clamp and be fixed on pipeline I 8 and pipeline II 9 outer surfaces by fastener, in clasp I 1 and clasp II 2, be along the circumferential direction provided with some slotted holes 11, mouth of pipe gap 10 between pipeline I 8 and pipeline II 9 is positioned at the below of slotted hole 11.Clasp I 1 and clasp II 2 are buckled in the pipeline I 8 and pipeline II 9 that needs welding, and lock by fastener, clasp I 1 after locking and clasp II 2 are that a circle is wrapped in pipeline I 8 and pipeline II 9 outer surfaces, thereby make the dead in line of pipeline I 8 and pipeline II 9, therefore can not cause all well and good mouthful and the generation of rough phenomenon.During welding, welding rod is inserted from slotted hole 11,10 place's welding portion length in mouth of pipe gap, to unclamp fastener afterwards, clasp I 1 and clasp II 2 are removed from pipeline I 8 and pipeline II 9, the local repair welding of again 10 places, mouth of pipe gap not being welded is afterwards complete, can realize the butt welding work of pipeline, simple and fast, has improved efficiency.

As shown in Figure 1, fastener can be for following structure it comprise the ear seat I 3 and the ear seat II 4 that are arranged at respectively clasp I 1 and clasp II 2 both sides, be fixed on the jack 5 in ear seat I 3 and be arranged at the hook groove 7 in ear seat II 4, the upper end of link 6 is connected in the piston rod head end of jack 5, and its lower end is placed in hook groove 7.When needs are fastening, by operation jack 5, make its piston rod protruding, thereby piston rod pulls link 6 to move, therefore link 6 has been realized spacing tension between clasp I 1 and clasp II 2 owing to being stuck in hook groove 7, thereby it is clamped on pipeline I 8 and pipeline II 9 outer surfaces.Simple in structure, rapid operation, has improved efficiency.

As shown in Figure 3, can also comprise and along the circumferential direction be fixed on the some nuts 13 in clasp I 1 and clasp II 2 and be combined on bolt 14 in each nut 13, the bottom of each bolt 14 contacts with the outer surface of pipeline I 8.When by clasp I 1 and clasp II 2 by pipeline I 8 and pipeline II 9 fixing after.Thereby can realize the radial position of accurate adjustment pipeline I 8 by rotating each bolt 14, the inwall of guaranteeing pipeline I 8 is adjusted to the inwall of pipeline II 9 and axially overlaps, improved the accuracy of adjusting.Further guaranteed the quality of welding.

As shown in Figure 4, also comprise and be along the circumferential direction arranged at the some circular holes 12 in clasp I 1 and clasp II 2 and be plugged in each circular hole 12 and head end is conical lash adjusting device 15, the head end of lash adjusting device 15 is arranged in mouth of pipe gap 10.Because the head end of lash adjusting device 15 is to continue after therefore pyramidal structure is inserted in circular hole 12 to promote forward to make gradually the spacing in mouth of pipe gap 10 to increase, thereby realized the object in convenience adjustment mouth of pipe gap 10, further guaranteed welding weld bond quality.
