Detailed description of the invention
Dish-type positioning interval device as Figure 1-4, be provided with block plate 1, block plate 1 central authorities upside is provided with connecting hole 4, the fixed bar 8 vertical with block plate is plugged with in connecting hole 4, fixed bar 8 can move upward and to be separated with connecting hole 4, block plate 1 periphery is evenly equipped with and has flexible location wing plate 2, location wing plate is fan-shaped or trapezoidal, and wing plate downside, location is provided with downslide barrier rib 3.The inner end of location wing plate 2 is fixedly connected with block plate, the inner of location wing plate is positioned at same plane and reclines connected successively, be bent upwards outside location wing 2 plate, outer edge is when being positioned at sustained height, the adjacent edges of adjacent two location wing plates recline or superimposed, location wing plate 2(plastics mutually) and block plate 1 form the airtight space disc of circle centered by connecting hole 4.Location wing plate 2 use has flexible plastics and makes.
The present invention improves further, and the inner of described location wing plate 2 is vertical with fixed bar 8, outer end and fixed bar (axis) angle in 10-45 °, as can be seen from Fig. 1-Fig. 3, locates the angle that wing plate outer end and fixed bar are 30 ° in the present embodiment; In adjacent two location wing plates, the concave station 7,6 cooperatively interacted when (adjacent two location wing plate adjacent parts) are superimposed both the location wing plate upper side below the wing plate downside, location above sides adjacent is positioned at is positioned at sides adjacent is respectively equipped with.As can be seen from Fig. 1-3, location wing plate is formed by stacking by the location-plate that two pieces is quadrangle, and an end (location wing plate is inner) of two pieces of location-plates is completely overlapping, the 0.2-0.8 of the other end (locating wing plate outer end) its width of two pieces of location-plates is overlapping; Part underlapped on two pieces of location-plates be adjacent two location wing plate adjacent edges superimposed time the concave station that cooperatively interacts, as can be seen from the figure, concave station is triangular in shape.Location wing plate being inclined upwardly relative to block plate upper side from-inner-to-outer, as can be seen from Figure 5, when positioning interval device enter diameter be less than in the big gun hole of space disc diameter time, the outside of location wing plate is bent upwards, some is overlapping at the concave station place of wing plate 2 outside, adjacent two location, the thickness of lap is identical with the thickness of location wing plate, space disc good leak tightness, and explosive is not easily lower to be leaked; When after location wing plate and big gun hole contact internal walls, rotate fixed bar press space disc in big gun hole while, to the side that location wing plate is higher, space disc can be driven to rotate and enter in big gun hole, reduce stop and the friction of hackly big gun hole inwall contraposition wing plate, fixed behaviour is more laborsaving, raises the efficiency.Described fixed bar is provided with external screw thread, and fixed bar is connected with extension bar through external screw thread; The extension bar installing different length can be coordinated according to the degree of depth in big gun hole.
The present invention improves further, taper type big up and small down in the middle part of described block plate 1, connecting hole 4 is bellmouth, on the inwall of bellmouth, circumference is evenly equipped with at least two multiple edge body shape draw-in grooves 5 vertical with bus, fixed bar 8 lower end is provided with the taper type grafting block 9 matched with connecting hole 4, grafting block 9 is provided with groove, outer surface and the grafting block periphery shell fragment 10 on same taper seat is provided with in groove, shell fragment 10 is provided with the snap fit tabs 11 matched with draw-in groove 5, snap fit tabs 11 1 side (the side homonymy higher with nearest location wing plate) for draw-in groove inside fit face directly, opposite side is inclined-plane.When the grafting block 9 of fixed bar inserts in taper connection hole 4, snap fit tabs 11 embeds in draw-in groove 5, rotates forward fixed bar, facing directly inside side and draw-in groove of snap fit tabs 11 is fitted, and drives block plate to rotate; Rotate backward fixed bar, snap fit tabs inclined-plane can in draw-in groove relative sliding, when block plate rotate be subject to certain resistance time, snap fit tabs can press curved in shell fragment 10, skid off in draw-in groove 5; Carry fixed bar 8 now, fixed bar moves upward and to be separated with connecting hole 4.During use, be plugged on by fixed bar in the connecting hole of block plate, when without external force, the two is not easily separated, is applicable to use when big gun hole upper diameter is larger, installs easier.
Connecting hole described in the present invention also can be many ribs hole or pyramid hole, and fixed bar lower end is provided with the terrace with edge coordinated with many ribs hole or the grafting of pyramid hole.
The present invention in use, fixed bar is inserted in connecting hole, fixed bar is used to be pressed into by space disc in big gun hole, location wing plate outside be bent upwards, with the inwall close contact of positioning disk in big gun hole, two adjacent location wing plate portions are superimposed, and location wing plate and block plate form tight bowl-shape space disc.When space disc enters the appropriate depth in big gun hole, propose fixed bar, explosive can be placed on the upside of space disc.Structure of the present invention is simple, with low cost, simple to operation, without the need to using any gas and high pressure tank, substantially increases efficiency and the security of mining production.
The present invention is by pressing down and be rotatably connected the action bars on fixed bar, just fanhole(s) locator can be put into the optional position in big gun hole, no matter be that dry hole and water hole can use, after position determines, by rotating lengthening bar, just fixed bar can be withdrawn, only space disc be stayed inside big gun hole, this method of operating is simple, efficient, and dry hole, water hole can be general.
