Detailed description of the invention
nullAs shown in Fig. 1 to Fig. 6，A kind of many pipe joints header welding device，It includes rigidity girder 1，Rigidity girder 1 two ends are separately installed with arm-tie 2，The quantity of arm-tie 2 and position can be adjusted with factors such as welding positions according to the actual requirements，Header through hole 8 is had on arm-tie 2，Guide rail 9 also it is installed with on rigidity girder 1，Guide rail 9 is arranged between two arm-ties 2，This position is also can be adjusted according to the actual requirements etc.，The riser 1-2 that guide rail 9 is arranged by two pieces of spacing side by side is formed，Guide rail 9 both sides are mounted on reinforcing plate 1-3，Be provided with activity on guide rail 9 holds out against slide block 3，Hold out against the arc that slide block 3 side is provided with header 7 surface engagement and be adjacent to face，Middle by the header of the modes such as shimming and similar sizes specification with the use of，Hold out against to be provided with between slide block 3 opposite side and rigidity girder 1 and make to hold out against slide block 3 and be closely attached on the wedge structure of header 7，Specifically include fixing wedge and the movable tapered wedge 4 of cooperation，Fixing wedge includes fixing wedge seat 6 and fixing tapered wedges 5，Fixing wedge seat 6 is installed on rigidity girder 1 by screw bolt and nut cooperation，Wherein can increase cushion block to adjust position before and after wedge structure，Be conducive to whole header welding anti-deformation，Fixing tapered wedges 5 is fixedly installed in fixing wedge seat 6，Movable tapered wedge 4 is arranged at fixing tapered wedges 5 and holds out against between slide block 3，Movable tapered wedge 4 is perpendicular with the contact surface holding out against slide block 3，Fixing tapered wedges 5 is 5 ° to 8 ° with the wedge oblique angle of movable tapered wedge 4，Use less wedge oblique angle，Ensure there is self-locking action，Will not get loose in the course of the work；Fixing tapered wedges 5, holding out against slide block 3 both sides and be provided with support rim, fixing tapered wedges 5, the lower surface of the support rim holding out against slide block 3 are supported in guide rail 9 upper surface；Rigidity girder 1 is made up of with gusset 1-7 H profile steel 1-1, rigidity girder 1 bottom welding equipment has lower support plate 1-5, top welding equipment to have handling otic placode 1-6, it is convenient to use and the handling of rigidity girder 1, on rigidity girder 1, also welding equipment has connecting plate 1-4, and arm-tie 2 coordinates, by bolts and nuts, the connection realized with connecting plate 1-4 thus is installed on rigidity girder 1.
Operating process is as described below: rigidity girder 1 is placed in header 7(workpiece) weld diastrophic opposite side, arm-tie 2 is inserted in header 7(workpiece) two ends, adjust rigidity girder 1 and header 7(workpiece) relative distance, rigidity girder 1 is joined with bolts with arm-tie 2, wedge is fixed seat 6 and fixing tapered wedges 5 screw connects fixing, then with bolt, wedge is fixed seat 6 to be fixed on rigidity girder 1, the lower surface making the both sides boss of fixing tapered wedges 5 abuts against guide rail 9 upper surface so that it is stress is reliable.Being placed on guide rail 9 holding out against slide block 3, the lower surface of its both sides boss contacts with guide rail 9 upper surface, makes to hold out against slide block 3 simultaneously and abuts against header 7(workpiece) on.Movable tapered wedge 4 be placed in fixing tapered wedges 5 with hold out against slide block 3 in the middle of, the inclined-plane of movable tapered wedge 4 matches with the inclined-plane of fixing tapered wedges 5, the upper end of movable tapered wedge 4 is tapped again with instruments such as hammers, make to hold out against slide block 3 and header 7(workpiece) compress, thus the installation completing many pipe joints header anti-deformation device is fixed.During dismounting, coordinate with hammer and push rod, below guide rail 9, tap the bottom of movable tapered wedge 4, make wedge structure get loose.Back out the fixing bolt of arm-tie 2 and rigidity girder 1, from header 7(workpiece) take down arm-tie 2, just dismantled.
The size of arm-tie 2 mainly determines bore size with the outside dimension of concrete header plus certain fit-up gap, and in header, the adnexa such as primary tube joint and otic placode needs rationally to dodge simultaneously, determines length dimension etc. with this.Corresponding header is coordinated to use, to ensure versatility of the present utility model by changing various sizes of arm-tie 2.
