U-shaped pipe nozzle flange supporting device for welding
Technical field
The utility model relates to U-shaped pipe nozzle flange welding technology field, is specifically related to the bracing or strutting arrangement during welding of U-shaped pipe nozzle flange.
Background technology
At present, during the welding of U-shaped pipe nozzle flange, U-shaped pipe directly places support on the ground.And during nozzle flange welding, need 360o to rotate U-shaped pipe, the rotation of usual U-shaped pipe needs two workmans, not only waste time and energy, and cannot ensure that the mouth of pipe of the U-shaped pipe after rotating is horizontal all the time, once U-shaped pipe tilts, the weldquality of U-shaped pipe nozzle flange and the U-shaped pipe mouth of pipe just cannot ensure.
Utility model content
The purpose of this utility model is: provide one can effectively support U-shaped pipe, and the U-shaped pipe nozzle flange supporting device for welding of energy ease rotation U-shaped pipe.
For achieving the above object, the technical solution adopted in the utility model is: U-shaped pipe nozzle flange supporting device for welding, comprise: bracing frame, described bracing frame comprises bottom support platform, bottom support platform is provided with a pair circular base slab, each circular base slab is by semicircle first Hough gripper shoe and the involutory fixing formation of semicircle second Hough gripper shoe, the straight edges of boards of semicircle first Hough gripper shoe and semicircle second Hough gripper shoe offer two semi-circular recesses respectively, corresponding semicircle first, second Hough gripper shoe is involutory makes the semi-circular recesses on it be combined to form two circular support hole respectively, two circular support hole on each circular base slab all can clamp on the tube wall of two straight lengths being supported on U-shaped pipe respectively, described bottom support platform is provided with two pair rollers, and each circular base slab to be supported on respectively on a pair roller and can to rotate on this pair roller, all the time horizontal positioned state is in by the U-shaped pipe that circular base slab supports.
Further, aforesaid U-shaped pipe nozzle flange supporting device for welding, wherein, a pair circular base slab clamps the forward and backward two ends being supported on U-shaped pipe straight length respectively.
Further, aforesaid U-shaped pipe nozzle flange supporting device for welding, wherein, corresponding semicircle first Hough gripper shoe and semicircle second Hough gripper shoe are fixed by clamping screw is involutory removably.
The utility model has the advantage of: during nozzle flange welding, as long as rotate two pieces of circular base slabs, it is made to rotate on two pair rollers respectively, such U-shaped pipe just can rotate 360o very easily, and make the mouth of pipe of U-shaped pipe remain at level, thus not only facilitate the welding of nozzle flange, improve welding efficiency, and effectively can ensure the weldquality of nozzle flange and the U-shaped pipe mouth of pipe.

Fig. 2 is the structural representation that in Fig. 1, A-A analyses and observe direction.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, U-shaped pipe nozzle flange supporting device for welding, comprise: bracing frame, described bracing frame comprises bottom support platform 1, bottom support platform 1 is provided with a pair circular base slab 2, each circular base slab 2 is by semicircle first Hough gripper shoe 21 and the involutory fixing rear formation of semicircle second Hough gripper shoe 22, the straight flange of each semicircle first Hough gripper shoe 21 and semicircle second Hough gripper shoe 22 offers two semi-circular recesses 3 respectively, corresponding semicircle first, second Hough gripper shoe 21, 22 involutoryly make the semi-circular recesses 3 on it be combined to form two circular support hole 4 respectively, two circular support hole 4 on each circular base slab 2 all can clamp on the tube wall of two straight lengths being supported on U-shaped pipe 5 respectively, described bottom support platform 1 is provided with two pair rollers 6, the bottom of each circular base slab 2 to be supported on respectively on a pair roller 6 and can to rotate on this pair roller 6, and the mouth of pipe of the U-shaped pipe 5 supported by circular base slab 2 is in horizontal positioned state all the time.In order to ensure whole U-shaped pipe 5 balance support, in the present embodiment, a pair circular base slab 2 clamps the forward and backward two ends being supported on U-shaped pipe 5 straight length respectively.In addition, in order to convenient disassembly, semicircle first Hough gripper shoe 21 corresponding in the present embodiment and semicircle second Hough gripper shoe 22 are fixed by clamping screw 7 is involutory removably.
Operation principle is as follows: open a pair circular base slab 2 respectively, the semi-circular recesses 3 in the circular first Hough gripper shoe 21 of HBV"liang dui ban" and semicircle second Hough gripper shoe 22 is made to lay respectively at the outside of two straight lengths at U-shaped pipe 5, then respectively clamping screw 7 is locked, make corresponding semicircle first Hough gripper shoe 21 and semicircle second Hough gripper shoe 22 involutory until semi-circular recesses 3 is combined to form circular support hole 4 and is clamped on the tube wall of two straight lengths of U-shaped pipe 5.When nozzle flange 8 welds, as long as rotate two pieces of circular base slabs 2, it is made to rotate on two pair rollers 6 respectively, such U-shaped pipe 5 just can rotate 360o very easily, and the mouth of pipe of U-shaped pipe 5 remains at level, thus not only facilitate the welding of nozzle flange 8, improve welding efficiency, and effectively can ensure the weldquality of nozzle flange 8 and U-shaped pipe 5 mouth of pipe.
