Abstract
The utility model discloses a corner cutting running ruler, and relates to an auxiliary device for corner cutting of angle steel for an iron tower in a power transmission line. The running ruler comprises a right-angle ruler with scales, and a strip-type steel plate for connecting two right-angle sides of the right-angle ruler, wherein strip-type sliding holes I of which the axes are parallel to the right-angle sides are formed in the two right-angle sides of the right-angle ruler; a strip-type sliding hole II of which the shape corresponds to that of the strip-type sliding holes I in the right-angle sides is formed in the strip-type steel plate; and the strip-type steel plate is connected with the right-angle ruler through matched bolts and nuts. When the running ruler is used as an auxiliary tool during corner cutting of the angle steel, a corner cutting line can be quickly drawn, the position accuracy of the drawn corner cutting line is high, the condition that the corner cutting line is wrongly drawn is avoided, and corner cutting efficiency is greatly improved.
Description
Technical field
The utility model relates to and a kind of steel tower in the transmission line of electricity is carried out the servicing unit of chamfer, specifically a kind of chamfer guiding ruler with angle steel.
Background technology
In Tower processing technique, the purpose of corner cut is a limb of angle iron component or two limbs to be cut a part bump with other member preventing.At present, the corner cut method generally has two kinds: a kind of is the method for mechanical shearing, generally shears at equipment such as punch press or hydraulic presses; Another kind is to carry out chamfer with thermal cutting modes such as flame cuttings.When the equipment such as punch press or hydraulic press are sheared, as long as first at the batch angle steel measures the corner cut size, draw tangent position, then adjust angle iron position and angle at platen, make tangent line aim at the lathe shearing tool, on platen, angle iron position is drawn with slate pencil again, only need angle steel is put the assigned address of the angle steel that slate pencil draws during afterwards with a collection of cutting corner of angle steel, the operation lathe is sheared, and the corner cut size just can guarantee consistent, and this mode efficient is very high.And in, large-scale angle steel is generally heavier, carry out corner cut if adopt the method for mechanical shearing, the labour intensity of lift to move angle steel is larger, also be subject to the restriction of machine tooling ability, the range of work, therefore adopt the chamfer modes of thermal cuttings more, but need to be on each root angle steel before the chamfer measure respectively length and the width that needs the chamfer size with ruler, and mark, again with slate pencil with the mark line to indicate the chamfer position.Because every angle steel all need be measured twice and just can draw the chamfer position, therefore have the problems such as the inaccurate and efficient in chamfer position is low, thereby even since angle steel in batches larger, machinery repeat to read the problem that the ruler data cause data to misread to cause the chamfer position to make mistakes.
The utility model content
The utility model technical issues that need to address provide and a kind ofly can draw fast the chamfer position, and can guarantee the position precision chamfer guiding ruler high, that be difficult for makeing mistakes when drawing the chamfer line of chamfer line.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
The chamfer guiding ruler, comprise the strip steel plate that graduated square is set and connects square two right-angle sides, the one axis strip slide opening I parallel with right-angle side is set respectively on two right-angle sides of described square, also be provided with the corresponding strip slide opening of the strip slide opening I shape II with right-angle side on the strip steel plate, be connected by equipped mutually screw bolt and nut between described strip steel plate and the square.
Further improvement of the utility model is: the middle part of described strip slide opening be rectangle, two ends for semicircle, the width of described strip slide opening is greater than the diameter of bolt and less than the external diameter of nut.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
With the setting-out of chamfer guiding ruler of the present utility model for the angle steel chamfer, can draw fast the chamfer line position, the chamfer line position accuracy that draws is high, and the setting-out degree of accuracy is also very high, has stopped to draw the situation that the chamfer line is made mistakes.
On two right-angle sides of square scale and strip slide opening are set all, the strip slide opening is set on the steel plate, square and steel plate are bolted, can regulate steel plate with respect to the position of square by bolt and strip slide opening, and then regulate the position in the inboard sideline of steel plate, to draw the chamfer line that needs at different angle steel or to draw different chamfer lines at the angle steel of specification of the same race.In addition, select square as the parts of chamfer guiding ruler, square can be close on two right-angle sides of angle steel, provide benchmark to drawing the chamfer line.
The two ends of the strip slide opening of square and steel plate are semicircle, have increased the intensity of square and steel plate end.The width of strip slide opening is greater than the diameter of bolt, so that bolt is more smooth and easy during adjusting position in the strip slide opening; The width of strip slide opening can make nut that square and steel plate are effectively linked together less than the external diameter of nut, is unlikely to square and steel plate from bolt falling.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details:
A kind of chamfer guiding ruler comprises square 1 and steel plate 2 as shown in Figure 1, all is provided with scale and strip slide opening I 12 on two right-angle sides of square 1, and the axis of strip slide opening I 12 is parallel with two right-angle sides respectively.Scale on two right-angle sides is used for arranging the size of chamfer, and the middle part of strip slide opening is that rectangle, two ends are for semicircle.Steel plate 2 is strip steel plates, and also available ruler replaces, and is provided with strip slide opening II 22 on the steel plate 2, and strip slide opening II 22 is corresponding with strip slide opening I 12 shapes, and the middle part of strip slide opening II 22 is that rectangle, two ends are for semicircle.Square 1 is connected with steel plate and is connected by two bolts 3, and by with the supporting nut screwing clamping of bolt 3.Bolt 3 passes the strip slide opening of square 1 and steel plate 2, and can adjust steel plate 2 with respect to the position of square 1 by the position of adjusting in the strip slide opening of bolt 3 on square 1 and steel plate 2.Mixing up on demand tights a bolt behind the position 3 can form a complete right angled triangle, the inboard right-angle side form right angle leg of square 1 wherein, the inner side edge form right angle hypotenuse of steel plate 2, wherein the size of two right-angle sides can read out by the scale on the square 1.
During use, unclamp first bolt 3, adjust bolt 3 strip slide opening I 12 interior positions on square 1, bolt 3 drives the right angled triangle that steel plate 2 moves to form different sizes, when the size of two right-angle sides of formed right angled triangle just in time equals the length of required chamfer and width dimensions, tight a bolt 3 with fixing right angled triangle, then chamfer guiding ruler of the present utility model is come to the termination of the angle steel 4 that needs chamfer, one right-angle side of square 1 aligns with the termination of angle steel 4 chamfer limbs, another right-angle side aligns with the chamfer limb, as shown in Figure 2, after putting surely, with the inboard setting-out of slate pencil along steel plate 2, the hypotenuse of the right angled triangle that draws namely is the position line that needs chamfer.
