Abstract
The utility model discloses an intersection cultellation rapid measurement tool, which comprises two connecting poles mutually hinged on a center point, wherein rings are arranged on two ends of each connecting pole. The intersection cultellation rapid measurement tool has the advantages that: 1)the center of a joint of the directions of two projection lines is the center of projection after the directions of the two projection lines on the ground are determined, thus simpleness in operation and high working efficiency are achieved; 2) the center of the measurement tool is of a circular hollow structure, a felting needle capable of rotating is fixed on one side of the circular hollow structure, the length of the felting needle is accurately set, the felting needle is rotated to a preset indicatrix position to ensure that the felting needle is aligned to the center of circle so that the intersection center of the two direction can be accurately determined, high intersection accuracy is achieved; and 3)the intersection cultellation rapid measurement tool is made of an aluminium alloy, is solid and durable, has a light and handy structure, can be folded and unfolded freely, and is convenient for carrying.
Description
Technical field
The utility model relates to a kind of quick measuring tool of intersection cultellation of measuring the vertical projection position of high-altitude building observation point.
Background technology
In engineering survey; Often need the vertical projection position of high-altitude construction of structures observation station be marked out in ground survey; The most directly method is that the surveyor builds the institute's position of surveying setting in construction and sights prism; Supply the ground survey instrument to measure angle, distance or coordinate, and then the measuring point projected position is resolved ground.But in the real work often the danger of observation station position be difficult to climb and maybe can't found prism; Like the tower center of iron tower of power transmission line or electric pole or the hanging wire point of lead; At this moment the hanging wire points of transformer station's portal frame etc. can adopt a kind of indirect measuring method in addition, i.e. the method for direction intersection projection; Two diverse locations set up transit on ground; Observe aerial measuring point from different perspectives, project to ground, below then and emit two straight lines, then the direction intersection point of two straight lines promptly is the floor projections position of aerial observation point.
Principle of work:, require to measure vertical projection position, the ground O ' that certain electric force pole tower center hanging point is observation station O like Fig. 1.At first A0 sets up transit in the place on ground, sights observation station O, and the telescope of vertical rotary apparatus is made A1 and A2 respectively on ground then, and A0, A1, A2 and observation station O are in same straight line at this moment; Be located at the B0 place to instrument stand again, make B1 and B2 equally, this moment, B0, B1, B2 and observation station O were in same straight line, and the direction plotted point of two straight line A1-A2, B1-B2 so is the ground vertical projection O ' of aerial observation point O.
" the quick measuring tool of intersection cultellation " is mainly used in the aerial observation point carried out fast accurately cultellation.The method of tradition expression floor projections line is with two cords, and plotted point is confirmed in the intersection of fixing, stretch of its two ends.Since there is not special fixing device in the open air, therefore very inconvenience of operation, inefficiency, cord is flexible, and the intersection precision is not high.
Summary of the invention
The purpose of the utility model provides a kind of measuring accuracy height, the quick measuring tool of portable intersection cultellation.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The utility model is included in two connecting rods that central point is hinged, and the two ends of each connecting rod all are provided with annulus.
Hinged place at two connecting rods is provided with crosshair, and crosshair is connected with pricker.
Adopt the utility model of technique scheme, have the following advantages:
1) utilize the utility model to confirm two the projection line directions in ground after, the center of its direction intersection just is projection centre, and is simple to operate, high efficiency.
2) the measuring tool center is circular hollow structure, fixing aside rotatable pricker, and the length of this pricker is accurately set, and the rotation pricker makes it aim at the center that the both direction intersection can be accurately confirmed in the center of circle to predetermined index line position, and the intersection precision is high.
3) the quick measuring tool of intersection cultellation adopts aluminum alloy material, and durable, structure is light and handy, open amount to freely, easy to carry.
In addition; The utility model can also be used for the replacing of engineering survey ground stake; Such as being set, timber need be replaced by cement stake or other spud piles etc.; Utilize this moment the quick measuring tool of intersection cultellation to get off the mark heart stationkeeping of former stake position, the accurate setting-out that is used for when newly stake is provided with is restored.
Description of drawings
Fig. 1 is measuring principle figure.
Fig. 2 is the structural representation under the utility model open mode.
Fig. 3 is the structural representation under the utility model closure state.
Embodiment
Like Fig. 2, shown in Figure 3, the utility model is included in two connecting rods 1 that central point is hinged, and the two ends of each connecting rod 1 all are provided with annulus 2.In the hinged place of two connecting rods 1 is the circular hollow structure, and it can be an annulus, and crosshair 3 is set above that, and crosshair 3 is connected with pricker 4, and pricker 4 can rotate.
The principle of work of the utility model is: the annulus 2 at each connecting rod 1 two ends inserts measuring staff or common centering rod when intersection measurement; After the ground transit is sighted aerial measuring point; Rotary apparatus telescope commander surveyor uses measuring staff to make an end points and fixes equidirectional then another end points of making to measuring staff insertion ground; Instrument is removed the station and is sighted aerial measuring point again; Measure fixedly two end points of another one direction successively; Then confirmed two projection line directions, this moment, four end points of measuring tool relied on four measuring staffs that insert ground to be fixed in ground, and rotation intersection point pricker 4 is to the index line position; Below go out mark with thorn acupuncture on the timber that pre-sets of ground, be the floor projections central point of aerial observation point.
Need to prove, the whole aluminum alloy material that adopts of the utility model, simple in structure light and handy, cost of manufacture is low, and is easy to operate.
