Abstract
The utility model discloses a kind of foldable triangular minute hole chi, comprising: crossfoot and perpendicular chi, hinged between crossfoot and perpendicular chi; The free end of described crossfoot and perpendicular chi is connected by stay cord; Between crossfoot and perpendicular chi by bolted splice; Crossfoot and perpendicular chi middle part are provided with air level.The utility model adopts accordion structure, carries with easy to use, measures accurate quick, not limited by landform, has greatly saved the activity duration, has reduced manpower consumption, has improved work efficiency.
Description
Technical field
The utility model relates to location survey technical field of tools in transmission line construction.
Background technology
35KV and following electric line are measured requirement over the years, the location of often need to digging pit in setting up electric pole construction, distance between the electric pole setting up must meet Design Requirement Drawing, bury underground between the hole of electric pole and must meet electric pole Design Requirement Drawing, therefore in construction, should dig pit in strict accordance with figure paper size, guarantee construction quality.In existing operating technique, use transit, line rod, tape measure to dig pit and position setting up in electric pole construction as combination tool.By using in real work, find that this combination tool is not only time-consuming but also require great effort in setting up electric pole construction, and sometimes because landform limits, the actual measured value drawing neither be very accurate.Especially rugged, tiltedly drape over one's shoulders on the ground, high point is determined the position in first hole again, when low spot is determined second willing position again, due to clinoform, use above-mentioned combination tool, can not guarantee the accuracy of two horizontal ranges between hole, can not guarantee construction quality, not meet the standard that 35KV and following transmission and distribution line are built.
Utility model content
The utility model provides a kind of foldable triangular minute hole chi, adopts accordion structure, carries with easy to use, measures accurate quick, not limited by landform, has greatly saved the activity duration, has reduced manpower consumption, has improved work efficiency.
Technical solution adopted in the utility model is:
Foldable triangular divides a hole chi, comprising: with crossfoot and the perpendicular chi of scale, hinged between crossfoot and perpendicular chi; The free end of described crossfoot and perpendicular chi is connected by stay cord.
Preferably, between crossfoot and perpendicular chi by bolted splice.
Preferably, crossfoot and perpendicular chi middle part are provided with air level.
Preferably, crossfoot and perpendicular chi are Collapsible structure.
This instrument is used in actual job, if longitude and latitude selected after, with this chi, divide hole, not limited by landform, greatly saved the activity duration again, reduced manpower and expended.
This instrument is as extensively used in 35KV and following electric line set up, and the most direct benefit is exactly greatly to shorten prospecting in early stage to measure the duration, and then accelerates the circuit progress that puts into operation, the optimum ratio of formation inputoutput early; Secondly in cost control, can reduce manpower uses approximately 40% exactly, from the overall general layout of large electrical network, large construction over the years, has in mind, makes power grid construction fund flower in the input of equipment and technology and research and development, has saved human cost input; Again, be exactly to expend the most significant man-hour to save above, under the prerequisite that the utilization of this instrument can be equal in workload, shorten the activity duration, reduce labour intensity.
The beneficial effect that adopts technique scheme to produce is:
1, the utility model employing crossfoot and perpendicular chi are hinged, are scalable, folding structure, carry with easy to use, measure accurate quick, not limited by landform, have greatly saved the activity duration, have reduced manpower consumption, have improved work efficiency.
2, adopt air level auxiliary adjustment to divide the level of cheating chi, measure more convenient and quicker, further improved work efficiency.
3, the utility model is simple in structure, easy to use, has high promotional value.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
1, crossfoot; 2, perpendicular chi; 3, stay cord; 4, bolt; 5, air level.
Embodiment
Foldable triangular divides a hole chi, comprising: with crossfoot 1 and the perpendicular chi 2 of scale, hinged between crossfoot 1 and perpendicular chi 2; The free end of described crossfoot 1 and perpendicular chi 2 is connected by stay cord 3.
Another technical scheme of the utility model is that crossfoot 1 and perpendicular chi 2 are Collapsible structure.
Another technical scheme of the utility model is, hinged by bolt 4 between crossfoot 1 and perpendicular chi 2.
Another technical scheme of the utility model is that crossfoot 1 and perpendicular chi 2 middle parts are provided with air level 5.
Before construction survey, first will erect chi 2 and crossfoot 1 hinged and fixing by bolt 4, make to form right angle between perpendicular chi 2 and crossfoot 1, then two free ends at perpendicular chi 2 and crossfoot 1 are connected stay cord 3.
After transit is selected, determine first position, hole, regulating the link of crossfoot 1 and perpendicular chi 2 is that root is opened half of distance, the right-hand member of crossfoot 1 is aimed to first position, hole, then will divide hole chi to carry out flip horizontal, adjusting level, determines position, second hole with the left end of crossfoot 1.
Crossfoot 1 and perpendicular chi 2 can adopt the line rod of sign red and white, and the folding overcasting staff of can doublely doing is afterwards used.
As long as after longitude and latitude is selected, divide hole with this chi, limited by landform, greatly saved the activity duration again, reduced manpower and expended.
