Abstract
The utility model belongs to the connection technique of pipelines, which is divided into a lineation gauge and a lineation shelf, wherein, the lineation gauge is composed of a fixing foot, a slide sleeve barrel and a rotary foot. The slide sleeve barrel is sheathed on a fixing foot rod and can be slid upwards and downwards. The upper end of the rotary foot is connected to the slide sleeve barrel. A lineation foot of the lower end of the rotary foot is hinged on a rod shelf. The lineation shelf is composed of a transverse shelf rod, a vertical shelf rod and positioning slide blocks. The vertical shelf rod is positioned on the midpoint position of the transverse shelf rod. The transverse shelf rod is provided with a chute for moving leftwards and rightwards two positioning slide blocks. The inner sides of the positioning slide blocks are arc shapes which are anastomosed and matched with a pipeline wall.
Description
The utility model belongs to pipeline connection technology, mainly proposes a kind of chalker of mutually high pipeline tapping.
Pipelayer's journey accounts for the sizable part of whole building installation engineering, and in the pipeline installation process, branching of pipes and intersection are again the problems that often runs into.The conventional construction method that intersects pipeline is at first to carry out laying-down with the expansion collimation method on felt, model is cut be applied to the model line of pipeline upper edge more then, at last could cutting along the line.This construction method generally needs three process, and needs the long time, for the setting-out again again of different calibers, and very loaded down with trivial details; And mapping is the approximation method that adopts with straight Dai Qu, and therefore the continuity of the typical curve of releasing is limited, and error is also bigger.
The purpose of this utility model promptly is to propose a kind of chalker that is used for intersecting pipeline tapping, utilizes it directly to rule at tube surface, thereby increases work efficiency, guarantees the accuracy and the continuity of intersection curve.
The utility model is finished the technical scheme that its invention task taked: it is divided into marking gauge and scribing block; Wherein marking gauge is made up of fixing feet, sliding sleeve and rotation pin, sliding sleeve is enclosed within on the bridge of fixing feet can slide up and down the adjustment upper-lower position along bridge, rotate that the pin upper end is connected on the sliding sleeve and hinged with it, the line pin that rotates the underfooting end is hinged on and rotates on the foot lever frame.Adjust sliding sleeve and can adjust fixing feet and rotate spacing between the pin, rotate underfooting end line pin and can guarantee the parallel of fixing feet and rotation pin with the articulated structure of bridge at the upper-lower position on the fixing feet.
Scribing block is by cross bar, and perpendicular hack lever and positioning sliding block are formed, and perpendicular hack lever is positioned at the point midway of cross bar, sets the chute for two positioning sliding block move left and right on the cross bar, and the inboard of positioning sliding block is for kissing the arc of joining with tube wall.Positioning sliding block can be adjusted the position arbitrarily according to the size of caliber, and perpendicular hack lever so perpendicular hack lever overlaps with the extended line of the arm axis of required opening, so just can guarantee the quality of the arm aperture lines of drawing owing to be between two positioning sliding blocks.
The special use line instrument of the crossing pipeline tapping that the utility model proposes can directly be rule at tube surface, has save traditional setting-out operation, compare with traditional opening scribble method, not only save time but also laborsaving, can improve 3～5 times of work efficiency, practical function is bigger in pipeline engineering.
Embodiment:
Accompanying drawing 1 is the marking gauge structural representation.
Schematic diagram when accompanying drawing 2 is adjusted lead pin pitch for marking gauge.
Accompanying drawing 3 is the scribing block structural representation.
Accompanying drawing 4 is the vertical view of Fig. 3.
With reference to accompanying drawing its structure is further specified:
Shown in accompanying drawing 1,2, marking gauge is made up of fixing feet 2, sliding sleeve 1, rotation pin 3 three parts, sliding sleeve 1 is enclosed within can slide up and down on the bridge of fixing feet 2 adjusts the position, rotate that pin 3 upper ends are connected on the sliding sleeve 1 and hinged with it, the line pin 4 that rotates the underfooting end is with to rotate the foot lever frame hinged.Need to adjust fixing feet 2, when rotating the spacing between the pin 3, sliding sleeve 1 adjusted the position downwards get final product, the line pin 4 that rotates pin 3 lower ends is designed to articulated structure with bridge, can guarantee fixing feet and rotate the parallel of pin.
Shown in accompanying drawing 3,4, scribing block is by cross bar 6, and perpendicular hack lever 7 and positioning sliding block 5 are formed, and perpendicular hack lever 7 is positioned at the point midway of cross bar 6, set the chute 8 for two positioning sliding block 5 move left and right on the cross bar 6, the inboard of positioning sliding block 5 is for kissing the arc of joining with tube wall.Be provided with the clamp nut of positioning sliding block location.
Use operation of the present utility model:
1, the line on trunk line, when the trunk line upper shed, at first want centering to intersect the direction of angulations of pipeline, be the angle in two-phase traffic control road, then the fixing feet of the planing axis direction along arm fixed, adjust to the radius value of arm rotating pin, rotate moving pin, promptly form a space curve on the surface of trunk line, this line is the aperture position line of pipeline, and the open-work of trunk line has promptly been finished in cutting along the line.
2, in the line on the arm: when ruling, at first utilize two adjustable positioning sliding blocks on arm, scribing block is fixed on the openend of arm, this moment, the center line of perpendicular hack lever promptly was the extended line of arm axis.After fixing scribing block, on the perpendicular hack lever of scribing block, find out the radius value of trunk line and the angle of cut in two-phase traffic control road, and draw circle with planing on the surface of arm as the center of circle and radius value, on the surface of arm, promptly form a space curve, this line is the aperture position line of arm, and the open-work of arm has promptly been finished in cutting along the line.
