The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is A-A generalized section in Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
A kind of cable guide pipe mouth of pipe location of the core device as shown in Figure 1 and Figure 2, it comprises a semicircular location mainboard 2, radially offer three slideways 3 on the mainboard 2 of location centered by the center of circle of location mainboard 2, slideway 3 slidably connects mark post 4, and the axis of mark post 4 is through the center of circle 9 of location mainboard 2
In the present embodiment:
Be provided with slideway slide block 7 in mark post 4 lower surfaces, slideway slide block 7 is slidably connected with slideway 3.Promote slideway slide block 7, can promote mark post 4 and move.
Slideway slide block 7 other ends pass slideway 3, and slideway slide block 7 is fixedly connected with limited block 6, offer two through holes on limited block 6, and through hole lays respectively at slideway slide block 7 both sides, are provided with the first Limit screw 10, the first Limit screws 10 in through hole and are connected with through hole whorl.After mark post 4 moves into place, by tightening the first Limit screw 10, make it prop up location mainboard 2, can limit the movement of mark post 4.
Mark post 4 ends are triangular shape, and after can guaranteeing that mark post 4 moves into place, mark post 4 contacts with cable guide pipe inwall point, guarantee certainty of measurement.
Mark post 4 outer ends are connected with limiting plate 5, and limiting plate 5 is vertical with mark post 4; Can guarantee that like this mark post 4 can only be along the moving radially of cable guide pipe, and not overturn.
Slideway 3 is provided with scale, and the inner end of the length that the scale initial value is mark post 4 and slideway 3 is to the summation of the distance in the center of circle 9 of location mainboard 2.By reading the scale reading of mark post inner end on slideway, can regard as cable guide pipe mouth of pipe radius like this, convenient and swift.The scale initial value of slideway 3 also can be zero, and now cable guide pipe mouth of pipe radius equals the summation of the inner end of the length of the scale reading of mark post 4 inner ends on slideway 3, mark post 4 and slideway 3 to the distance of the central point of location mainboard 2.
Described location mainboard 2 is connected with gag lever post 1 by the second Limit screw 8, gag lever post 1 be arranged in parallel with location mainboard 2, the length of gag lever post 1 is greater than the length of cable guide pipe nozzle diameter, be specially: location mainboard 2 offers many group through holes vertically, every group of through hole at least is provided with two, in through hole, with the second Limit screw 8, is threaded; Gag lever post 1 radially is provided with groove, and groove is threaded with the second Limit screw 8.
In use, its using method is:
1), on-the-spot for steel ruler measure the cable guide pipe diameter, calculate the cable guide pipe radius;
2), three mark posts are outwards slided one by one, when mark post 4 inner ends equal the cable guide pipe radius at slideway 3 high scale readings, the first Limit screw 10 is tightened, by mark post 4 location on the mainboard 2 of location.
3), when the mouth of pipe central point of registration wire conduit upper end, one of the location mainboard 2 of limited location plate 5 is faced down, limiting plate 5 on mark post 4 is close to the cable guide pipe internal wall of pipe orifice, and with gag lever post 1 strut rail, at the cable guide pipe mouth, this timer relies on gravity naturally to be fixed on cable guide pipe;
When the mouth of pipe central point of registration wire conduit lower end, can lay down gag lever post 1, one of limited location plate 2 is faced up, the limiting plate 5 on mark post 4 is close to cable guide pipe mouth of pipe scope place inwall, limiting plate 5 enters the degree of depth of cable guide pipe and by cable guide pipe, is not blocked and be advisable with top, the center of circle, with hand, device is held;
The center of circle 9 of now locating mainboard is the center of circle of the cable guide pipe mouth of pipe.
The present invention utilizes two, center of circle radius to determine a circle, and then the center of circle of definite cable guide pipe mouth of pipe, can improve the positioning precision of cable guide pipe, cut the angle steel link of welding, cut off, polish, shorten the set-up time, there are characteristics simple in structure, convenient to use.
