The specific embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail embodiment:
As shown in Figure 1, the utility model is a kind of device that prevents the header welding deformation, the described device of header welding deformation that prevents comprises two end cage plates 1, two cover board mounts 2, be provided with a plurality of on the described end cage plate 1 and the supporting installing hole 6 of header body 5 external diameters, on the described end cage plate 1 connecting rod 7 is set, described connecting rod 7 is connected on the cover board mount 2, the two ends of described a plurality of header bodies 5 are set in the installing hole 6 of two end cage plates 1, between per two adjacent header bodies 5 a plurality of support bars 8 are set in described a plurality of header bodies 5.
Be set between described end cage plate 1 and the connecting rod 7 " T " font structure, connecting rod 7 passes cover board mount 2, and the end that cover board mount 2 contacts with ground is fixedlyed connected with support base plate 3.
Described end cage plate 1 is set to rectangular platy structure, installing hole 6 on the end cage plate 1 is provided with two, described two header bodies 5 are installed in respectively in the installing hole 6 of end cage plate 1 at two ends, described a plurality of support bar 8 is set to the different structure of length, support bar 8 length that are arranged on two end cage plate 1 centre positions are the longest, and the length of the support bar 8 of the end cage plate 1 of close both sides is the shortest.
Connecting rod 7 on the described end cage plate 1 is set to rotating structure on cover board mount 2, is the vertical angle structure between described connecting rod 7 and the cover board mount 2.
Described support bar 8 two ends all are set to recessed crescent structure, and crescent matches with the structure of header body 5 outer surfaces.
Described support bar 8 is the channel-section steel material.
Structure of the present utility model, before welded stub connection 4, earlier the two ends of header body 5 are respectively installed in the installing hole 6 of end cage plate 1 of both sides, with end cage plate 1 two ends of header body 5 are fixed, use the not isometric support bar 8 of regulation with its jack-up between two header bodies 5 successively, make header body 5 that the distortion of arcuate structure take place, carry out the welding of pipe joint 4 this moment, laggard line pipe joint welding linearity will reach qualified requirement.
Adopt the device that prevents the header welding deformation of the present utility model, cancelled the operation of proofreading and correct header body 1 linearity, reduced labor strength, and product quality is also further improved, reduced demand oxygen-acetylene.The two ends of two header bodies 5 are fixing with end cage plate 1, and the middle part uses the support bar 8 of not isometric channel-section steel material of 8 regulations with its jack-up successively, makes it bend to arc, carries out the welding of pipe joint 4 again in the outside of warp architecture.
Because header body 5 is when carrying out pipe joint 4 welding, local heating is local again cold, this just causes it to a side of welded pipe structure recessed arc-shaped deformation to take place, therefore, adopt structure of the present utility model, before welding, by structure of the present utility model, allow its arc that arches to a side of welded stub connection 4 change, so earlier, after the operation of welded stub connection 4 is finished, because the generation of shrinkage, header body 5 will be to the direction bending of opposite side, after welding is finished, after dismantling device of the present utility model, the linearity of header body 5 just just can standard compliant straight line requirement.
The two ends of each support bar 8 of the present utility model all are set to the crescent structure, such structure, be convenient to support bar 8 more stably be installed on two the association bodies 5 between, and not can because of stressed and mobile in addition jump out two the association bodies 5 between.
Structure of the present utility model, when two association's bodies 5 are installed in end cage plate 5, be up and down the structure of arranging, and be positioned at the height of association's body 5 of upside, the height of standing when just having adapted to operating personnel and being welded, therefore, after top association's body 5 carried out pipe joint welding, pivoting end cage plate 1 allowed up and down association's body 5 occurrence positions conversion, like this, just can be to being the welding of association's body 5 of below originally.So just be very easy to operating personnel, and reduced the labour intensity when welding.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the concrete realization of the utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or design of the present utility model and technical scheme are directly applied to other occasions without improving, all in protection domain of the present utility model.
