Description
Technical field
The present invention relates to the directional blasting operation, be specifically related to blasting operation auxiliary directional technology such as a kind of chimney, water tower and other cylindrical high-lager building.
Background technology
Along with country promotes the use of attention and the New Building Materials of environmental resource protection, the past was that the kiln factory of raw material baking red bricks is closed successively with the clay in recent years.After kiln factory closed, in order to reclaim, kiln body and chimney all will be removed, because chimney is tall and big, removed the method that chimney is taked directional blasting substantially.When cylindrical high-lager buildings such as explosion chimney, water tower, the buildings surrounding environment that has is very complicated, the direction that can collapse is limited in scope, sometimes have only 20～30 degree, this just requires orientation very accurate, thereby must be according to the impact point that collapses (G point) positioning operation impact point (H point) on chimney exactly.And in practical operation, on the chimney wall, accurately find ten fens difficulties of satisfactory operative goals point.Look for the method for operative goals point to mainly contain dual mode at present: the one, the people stands in the impact point that collapses (G point) and looks for operative goals point on the chimney wall by naked eyes, and this method deviation is very big.The 2nd, look for the H point with total station survey, though this method looks for the H point accurate than naked eyes are direct at the chimney wall, total powerstation not only price is expensive, and troublesome poeration, will have three people to cooperate just usually can finish.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of civil blast operation field auxiliary directional device, and it looks for a little accurate, easy and simple to handle, with low cost.
For achieving the above object, civil blast operation field auxiliary directional device of the present invention, comprise two long connecting rods, two long connecting rods are hinged at an one end points interaction, also comprise two short connecting rods, an end points of two short connecting rods is mutually hinged, and another end points is movably connected in respectively on two long connecting rods symmetrically.
Described short connecting rod is 1:3～5 with the length ratio of long connecting rod.
The tie point of described short connecting rod and long connecting rod apart from the length of the distance of two common end points of long connecting rod and long connecting rod than being 1:3～5.
The material of long connecting rod, short connecting rod is angle steel, lumps of wood bar or engineering plastics.
The present invention also provides and has used above-mentioned civil blast operation field auxiliary directional device to carry out the method for auxiliary directional, may further comprise the steps:
The impact point that collapses of the collapse direction of A, earlier definite chimney blasting operation;
B, with the end support of two long connecting rods of described civil blast operation field auxiliary directional device on the chimney outer wall, two long connecting rods that horizontally slip make the common end points sight alignment of the common end points of the impact point that collapses, two long connecting rods, two short connecting rods;
C, with above-mentioned 3 become line to extend with the chimney outer wall to intersect, namely obtain the operative goals point.
Technique scheme meets in the geometry isosceles triangle perpendicular bisector that two summits and circle on the outer arbitrary base of circle intersect necessarily through the principle in the center of circle.Operation process is simple, and the operative goals point location is accurate, and manufacturing cost and operating cost are all extremely cheap.
Description of drawings
Fig. 1 is principle schematic of the present invention;
Fig. 2 is the structural representation of civil blast operation field auxiliary directional device of the present invention;
Fig. 3 is the structural representation of civil blast operation field auxiliary directional device embodiment two of the present invention.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing.
Embodiment one
As Fig. 1, Fig. 2 as seen, the center of circle of chimney 3 is the O point, the impact point that collapses is the G point shown in Fig. 1,2 of A, D are two long connecting rods 1,1 ' active distal end, 2 of B, C are two short connecting rods 2,2 ' and two long connecting rod 1,1 ' tie point, the E point is two short connecting rods 2,2 ' common end points, and the F point is two long connecting rods 1,1 ' common end points.
△ AFD is an isosceles triangle, and AF=DF, A, D intersect at A, D 2 points with circle O respectively.Make BC ∥ AD, EB=EC, EF fixes on the △ AFD perpendicular bisector with regard to one so, prolongs FE and meets at the H point with circle O, and the H point namely is the point that will look for.B, C, E, F four points of connection should guarantee four connecting rod activities freely.
Civil blast operation field auxiliary directional device of the present invention, comprise two long connecting rods 1,1 ', two long connecting rods 1,1 ' hinged at an one end points interaction, also comprise two short connecting rods 2,2 ', two short connecting rods 2, an end points of 2 ' are mutually hinged, and another end points is movably connected in respectively on two long connecting rods 1,1 ' symmetrically.
Described short connecting rod is 1:3～5 with the length ratio of long connecting rod.
Two long connecting rods 1 of tie point distance of described short connecting rod and long connecting rod, the distance of 1 ' common end points are 1:3～5 with the length ratio of long connecting rod.
Be adapted to China rural area common be the kiln factory chimney external diameter of raw material baking red bricks with the clay, civil blast operation field auxiliary directional device of the present invention, two long connecting rods 1,1 ' length L
1At 1.2 meters～1.8 meters, two short connecting rods 2,2 ' length L
2At 30 centimetres～40 centimetres, the tie point of short connecting rod and long connecting rod apart from two long connecting rods 1,1 ' common end points apart from BF be 40 centimetres～50 centimetres comparatively suitable.L
1Preferably 1.5 meters, L
2Preferably 35 centimetres, preferably 40 centimetres of BF.
The material of long connecting rod, short connecting rod is angle steel, lumps of wood bar or engineering plastics.
As Fig. 1, Fig. 2 as seen, use above-mentioned civil blast operation field auxiliary directional device to carry out the method for auxiliary directional, may further comprise the steps:
The impact point that collapses of the collapse direction of A, earlier definite chimney blasting operation; This impact point that collapses (being the G point shown in Fig. 1) in the directional blasting operation process, requires chimney 3 to collapse along its center of circle O point and G point line direction.
B, two long connecting rods 1 of described civil blast operation field auxiliary directional device, 1 ' end (being A, D 2 points among Fig. 1) are supported on chimney 3 outer walls, the operator stands in the ABCD zone, two long connecting rods 1,1 ' that horizontally slip make the impact point G point that collapses, two long connecting rods 1,1 ' common end points F point, two short connecting rods 2,2 ' common end points E point sight alignment.
Civil blast operation field auxiliary directional device of the present invention owing to used bar linkage structure, thereby can be regulated two long connecting rods 1,1 ' subtended angle arbitrarily according to the chimney external diameter, has improved operation adaptability.
C, with 3 of above-mentioned G, F, E become line to extend with chimney 3 outer walls to intersect, namely obtain operative goals point H point.Perhaps on the chimney periphery to 2 lines of A, D, find the mid point of this line, be operative goals point H point.
In the directional blasting operation process, after accurately finding this operative goals point H point, can carry out the explosion design, thereby carry out directional blasting exactly according to job requirements.
Technical scheme provided by the present invention through a plurality of chimney explosion practices, proves that it is easy to use, just can accurately find the operative goals point in two minutes, actual measurement after operation is finished, and chimney collapse direction and design direction error are within ± 3 degree.
