Description
Technical field
This utility model belongs to connection triangle fields of measurement, relates to a kind of main foot rest being used for suspending in midair plumb bob in city, mine connection triangle measurement (connection survey).
Background technology
Connection survey is that ground survey coordinate system is delivered to underground, makes the measurement work that ground, underground coordinate system are consistent.In city underground, mining tunnel construction, because of the particularity of its construction, the method that connection survey needs to adopt connection triangle or Two-staged technique.Both approaches is required for that from ground, the plumb bob of 10kg weight is hung underground activities face by the steel wire of 0.3mm and implements connection survey work, and in measurement process, steel wire and plumb bob will remain static, otherwise will directly affect the precision of connection survey, thus the stability requirement of the support system hanging steel wire and plumb bob is significantly high.
Normal practice is that (vertical shaft, launching shaft periphery) sets up a very huge supporter at the construction field (site) with steel pipe, or adopts I-steel one suspension system of processing, suspends plumb bob in midair with steel wire.The shortcoming of this method is length consuming time, and because suspension system is very huge, impact construction, generally it is required for after being measured removing, when so next time implements connection survey, needs again to repeat to set up.Waste of manpower, material resources, financial resources.
Utility model content
In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of mobile flexible, easy to use, and can guarantee that " people " font foot rest of certainty of measurement, be used for suspending plumb bob in midair.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that
A kind of connection triangle is used for suspending in midair the foot rest of plumb bob in measuring, including: left ladder, right ladder, supporting leg.Described left ladder, right ladder all include the equal vertical beam of 2 root length degree and the equal crossbeam of many root lengths degree；Described supporting leg includes the equal vertical beam of 2 root length degree and many root lengths degree crossbeam not etc..Left ladder, the top of right ladder and the two ends of supporting leg are respectively provided with crossbeam, and left ladder, right ladder and supporting leg are linked together by the public crossbeam on top.The crossbeam at described supporting leg two ends is respectively mounted a pulley, the cylindrical roll of one winding steel wire of right side welding of right ladder.A steady rest is welded in the bottom of described right ladder.When described foot rest launches, left ladder and right ladder are in " people " font, and described steady rest keeps flat on the ground, and steady rest is placed above weight, and described supporting leg is propped up by the support bar being stuck on the crossbeam of described left ladder and supporting leg.
Further, described left ladder, right ladder the length of vertical beam be 1500～2000mm, left ladder, right ladder the length of crossbeam be 300～500mm.
Further, the length of the vertical beam of described supporting leg is 1500～2000mm, the crossbeam length respectively 300～500mm at the two ends of described supporting leg, 120～160mm.
Further, the diameter of described cylindrical roll is 150～200mm.
Further, the vertical beam of described left ladder, right ladder and supporting leg all adopts the square steel that the length of side is not less than 20mm.
Further, the public crossbeam of described left ladder, right ladder and supporting leg adopts diameter to be the round steel of 20mm；Other crossbeam adopts diameter to be the round steel of 6mm.
Further, described left ladder, the crossbeam of right ladder and the crossbeam of supporting leg are all equidistantly distributed.
Compared with prior art, this utility model has the advantages that
Connection triangle described in the utility model is used for suspending in midair the foot rest of plumb bob in measuring, be mainly made up of left and right ladder and supporting leg, simple in construction, lightweight, mobile flexible, and erection and dismounting are all very convenient.Both can guarantee that certainty of measurement, improve again measurement efficiency, save human and material resources and financial resources.
