Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
An adjustable clamp for quickly fixing a welded steel pipe comprises a square support 1, wherein a V-shaped positioning groove 11 arranged along the horizontal direction is formed in the upper surface of the square support 1; the end face of one end of the square support 1 is provided with a positioning cross rod 12 with the horizontal height lower than the upper surface of the square support 1, the square support further comprises a positioning plate 2 for connecting the positioning cross rod 12 and the square support 1, and four first positioning bolts 21 are vertically arranged on the positioning plate 2; the movable rod 3 is movably arranged on the upper surface of the square support 1 through a through hole arranged on the square support 1, a second positioning bolt 31 is arranged at the bottom end of the movable rod 3 along the horizontal direction, and the second positioning bolt 31 is clamped in a gap between every two adjacent first positioning bolts 21; the top end of the movable rod 3 is connected with a horizontal adjusting rod 5 through a horizontally arranged bearing 4, the tail end of the adjusting rod 5 is provided with an adjusting nut 51 with internal threads, and a jackscrew 52 with external threads is vertically screwed into the adjusting nut 51.
The movable rod 3 can move along the vertical direction through the through hole arranged on the square bracket 1, and the trend of the movable rod 3 moving along the radial direction is limited; the four first positioning bolts 21 form three mounting gaps, the second positioning screw 31 on the movable rod 3 is screwed into the mounting gaps, and the effect of fixing the movable rod 3 is achieved through the interaction between the first positioning bolts 21 and the second positioning bolts 31.
The utility model discloses the theory of operation of device does: measuring the outer diameter of the steel pipe to be welded, and enabling the lowest point of a jackscrew 52 to be higher than the top point of the steel pipe to be welded through the height of a first positioning bolt 21 on a positioning plate 2 and the height of a second positioning bolt thick-strip jackscrew 52 on a movable rod 3, and reserving a part of adjustment quantity; the adjusting rod 3 is rotated through the bearing 4, so that the lifting and the placement of the welded steel pipe are facilitated; place through V-arrangement constant head tank 11 and treat welded steel pipe and fixed, prevent that the steel pipe from rotating, it is right above the welded steel pipe to rotate the regulation pole 3 through bearing 4 again, through with jackscrew 52 screw in or screw out adjusting nut 51 finely tune the height of jackscrew 52, until support the top of taking welded steel pipe tightly, thereby play firm steel pipe position and prevent that the pipeline from rotating and rocking, then carry out weldment work, treat the welding and accomplish the back, anticlockwise screw out jackscrew 52, treat that the clearance appears in jackscrew 52 bottom and steel pipe, rotate regulation pole 3 through bearing 4, be convenient for take out the steel pipe.
