The utility model discloses a dysmorphism pilot hole and group to the piece realized the accurate positioning, fast organize right, and adopt anchor clamps, alone can accomplish different wall thicknesss nuclear equipment barrel and pipeline dress card, organize right, its simple structure, the cost that has maintained convenient to use, very big saving.
Description
Technical field
The utility model relate to be applicable to the pipeline welding of different wall core level group to fixture, the group that specifically can be applicable to core level pipeline and nuclear equipment cylindrical shell butt girth welding seam is right, right with group when can be used for other sheet material butt welding.
Background technology
In Nuclear Power Station installation process, relate to a large amount of core level equipment and the butt welding work of pipeline circumferential weld, when its welding, it is right that usual needs rigidly fix group, because the technical requirements such as both sides concentricity of workpiece, interior misalignment will be ensured on the one hand, on the other hand, also prevent its welding deformation.Current common way is as adopted roller bearing or chain block fastening or pipeline, and by the method for manual adjustment, dipstick metering range estimation, precision and efficiency are all very low; Indivedual manufactory adopts special pipeline assembling device, make to get up to waste time and energy, and versatility is bad.Therefore need to design a kind of simple fixture, be convenient to the group of nuclear equipment and pipeline circumferential weld to work.
Utility model content
The utility model provides a kind of group being applicable to the pipeline welding of different wall core level to fixture for the defect of prior art, can be cost-saving while group is fast right.Concrete technical scheme is as follows:
The group being applicable to the pipeline welding of different wall core level to a fixture, comprise rule, lower group to block, upper group to block; Described rule is rectangle, and centre has a rectangle pilot hole, and the top of pilot hole is provided with dovetail groove, and the inner edge up and down of described pilot hole has gradient, and the right and left along described pilot hole is provided with length scale.
Further optimization, during group pair, described rule is positioned over two pipeline joints, makes the zero graduation line of rule central authorities be positioned at the half place of pipeline wall thickness; Described lower group to be cross section to block and upper group to block be rectangular trapezoid block, and the gradient of trapezoid block hypotenuse and the gradient of inner edge up and down of described pilot hole match; First block is inserted to the rule pilot hole placed by lower group during group pair, make lower group to the trapezoidal right-angle side of block near two duct walls; Described upper group also has the dove-tail form projection matched with described pilot hole dovetail groove to block trapezoidal hypotenuse, lower group block is installed after, adopt dovetail groove by upper group to block and pilot hole pre-determined bit, then use instrument knock group to block, make group to block plugging in fitting hole and and pilot hole closely cooperate realize pipeline accurately organize right.
Further optimization, described core level pipeline wall thickness is between 3mm to 40mm.
Further optimization, described rule thickness is between 3mm to 10mm.
Further optimization, described pilot hole length is greater than core level pipeline wall thickness, between 60mm to 100mm.
The beneficial effects of the utility model are as follows:
Adopt a fixture just can be applicable to the core level pipeline welding group pair of multiple different wall, lower group only need be adjusted to block, the upper group of insertion to block for different wall nuclear equipment pipeline, simple to operate, features simple structure, and only need operating personnel just can complete pipe string and dismounting.And adopt rule raising group to accuracy, make lower group to block, upper group stressed more balanced to block, make group be difficult to deflection to pipeline, make follow-up welding more stable and improve weldquality.The utility model is easy to manufacture, easy to carry, avoids and adopts large-scale groups to fixture inefficiency, shortcoming that cost is high.
Accompanying drawing explanation
Fig. 1 is the utility model installment state structural representation.
Fig. 2 is A-A direction side view in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1-2, it is right that the utility model is used for the group of two nuclear equipment pipelines 1, fixture comprise rule 2, lower group to block 3, upper group to block 4.Rule 2 is rectangle, and centre has a rectangle pilot hole 5, and the top of pilot hole 5 is provided with dovetail groove 6, and the inner edge up and down 7 of pilot hole 5 has gradient, and the right and left along pilot hole 5 is also provided with length scale 8, and zero graduation line is in the centre of pilot hole 5.Lower group is cross section to block 3 and upper group to block 4 is rectangular trapezoid block, and the gradient of trapezoid block hypotenuse and inner edge up and down 7 gradient of pilot hole 5 match.Upper group also has the dove-tail form projection 9 matched with the dovetail groove 6 of pilot hole 5 to block 4 trapezoidal hypotenuse.
During group pair, make two nuclear equipment pipelines 1 close to each other, then rule 2 is positioned over the joint of two nuclear equipment pipelines 1, make the zero graduation line of pilot hole 5 central authorities in rule 2 be positioned at the half place of pipeline 1 wall thickness, to control stressed to block of group up and down.Then first block 3 is inserted to the rule pilot hole 5 placed by lower group, make lower group to the trapezoidal right-angle side of block 3 near two inner-walls of duct, to ensure that two inner-walls of duct are located along the same line.Lower group block 3 is installed after, adopt dovetail groove 6 and dove-tail form projection 9 by upper group to block 4 and pilot hole 5 pre-determined bit, then instrument is used to knock the group side larger to block 4, make group to block 4 gradually plugging in fitting hole 5 and and pilot hole 5 closely cooperate, now go up group to the trapezoidal right-angle side of block 4 near two pipeline outer walls, to ensure that two pipeline outer walls are located along the same line, realize thus pipeline accurately organize right.Weld complete when needing clamper for disassembling, only instrument need be used to knock the group side less to block 4, make group shift out pilot hole 5 gradually to block 4, fixture just can be made loosening, dismantle smoothly.
In practical application, the rule of fixture and upper group should adopt low-alloy high-strength steel to make to block, and upper group should adopt low-alloy steel to make to block, because clamp-shaped is simple, easily manufactured, decrease manufacturing cost, be applicable to the core level pipe string of wall thickness between 3mm to 40mm, and the rule thickness of correspondence is between 3mm to 10mm.And in order to adapt to different core level pipeline wall thickness, the pilot hole length being greater than core level pipeline wall thickness should be adopted, pilot hole length is selected to be advisable between 60mm to 100mm.
It is right that the utility model adopts special-shaped pilot hole and group to achieve accurate location, fast group to block, and adopt a fixture just can be applicable to the core level pipeline welding group pair of multiple different wall, and structure is simple, cost-saving, substantially increases group to efficiency.
Obviously, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if belong within the scope of the utility model claim and equivalent technology thereof to these amendments of the present utility model and modification, then the utility model is also intended to comprise these change and modification.
