Abstract
The utility model discloses a kind of king-post 3 D locating device, the semicircle anchor ear including two pairings；The both ends of semicircle anchor ear extend outward to form interconnecting piece along the diameter of anchor ear, and connection through-hole is offered on interconnecting piece, and bolt passes through the connection through-hole and connects two anchor ear pairings；It is set on one of anchor ear there are two location hole, the line and another location hole of one of location hole to the anchor ear center of circle to the angle between the line in the anchor ear center of circle are right angle；Prism bar is connected at the location hole of anchor ear.The utility model is simple in construction, easy to disassemble and assemble, two vertically disposed prisms enable it to the convenient suitable bridge that must obtain king-post to direction across bridge coordinate, in conjunction with the use of the measuring instruments such as total station, so that the three-dimensional coordinate measurement work of king-post is convenient and efficient.
Description
Technical field
The utility model relates to the fields of measurement of bridge king-post, and in particular to arrive a kind of king-post 3 D locating device.
Background technique
The construction survey of suspension bridge is because of the features such as its span is big, Sarasota is high, required precision is high, to our construction survey control
System brings many difficult and challenge.And king-post is influenced by factors such as sunshine, temperature, vibration, atmosphere in the construction process, tower
The axis of column can generate offset, and this is deviated commonly greater than king-post construction allowable error, so the construction Survey Control of king-post is
One of the key of king-post quality control on construction.
King-post operation side is very narrow, and the hollow tower column structure of common design, concrete wall thickness are narrower small at present.Tower
In column work progress, the crisscross intersection of steel construction is interfered with each other, and king-post anchoring piece measurement accuracy requires height, but measurement point position is by tower
Rod structure influence can only be arranged on narrow space, and the included common foot prop of measuring instrument is difficult to dispose, big by construction infection,
It is not easy to king-post structures construction survey.
Currently, the method that king-post construction survey placement instrument foot prop uses is generally the following two kinds:
1) by equipment placement in the ground control point far from king-post, this method measurement accuracy is influenced by long range sight
It greatly, can not daytime measurement and because king-post is by the deformation of Sunlight Action Sunday.
2) by equipment placement to the measuring table for riding upon king-post work surface, it is flat to set up and remove measurement for this method
Platform is time-consuming and laborious, and platform stabilization is bad, big by construction infection, influences measurement accuracy.
Utility model content
The utility model provides a kind of king-post 3 D locating device, efficiently and conveniently to realize the measurement work of king-post
Make.
In order to solve the above technical problems, the technology employed by the present utility model is
A kind of king-post 3 D locating device, the semicircle anchor ear including two pairings；Two are connected on one of anchor ear
A prism bar, the axle center of prism bar along long line by the center of circle of anchor ear, the line of one of prism bar to the anchor ear center of circle and another
One prism bar to the angle between the line in the anchor ear center of circle be right angle；Prism is connected to the top of prism bar.
According to above scheme, the both ends of the semicircle anchor ear extend outward to form interconnecting piece along the diameter of anchor ear, even
Connection through-hole is offered in socket part, bolt passes through the connection through-hole and connects two anchor ear pairings；On one of anchor ear
If there are two location hole, the line of the line of one of location hole to the anchor ear center of circle and another location hole to the anchor ear center of circle it
Between angle be right angle；The prism bar is connected at the location hole of anchor ear.
Compared with prior art, the utility model has the beneficial effects that simple in construction, easy to disassemble and assemble, two are vertically arranged
Prism enable it to the convenient suitable bridge that must obtain king-post to direction across bridge coordinate, in conjunction with making for the measuring instruments such as total station
With so that the three-dimensional coordinate measurement work of king-post is convenient and efficient.

Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing, the paraphrase of each label in figure
Are as follows: anchor ear 1, prism bar 2, interconnecting piece 3 connect through-hole 4, location hole 5.
The utility model includes the semicircle anchor ear 1 of two pairings, and the both ends of anchor ear 1 are along the straight radially outwardly extending of anchor ear 1
It stretches to form interconnecting piece 3, connection through-hole 4 is offered on interconnecting piece 3, bolt connects two 1 pairings of anchor ear after passing through the connection through-hole 4
It picks up and comes on banding to king-post.It is set on one of anchor ear 1 there are two location hole 5, one of location hole 5 arrives 1 center of circle of anchor ear
Line and another location hole 5 to the angle between the line in 1 center of circle of anchor ear be right angle.The bottom of cylindrical prism bar 2
It is greater than the disk of 2 diameter of prism bar equipped with a diameter, the diameter of prism bar 2 is slightly less than the diameter of location hole 5；The thickness of disk
Very little, about 1~2mm.Prism bar 2 passes through the location hole 5 of anchor ear 1, and the disk of 2 bottom of prism bar is then pressed to king-post by anchor ear 1
On, so that the axes extending line of prism bar 2 passes through the center of circle of anchor ear 1.The top of each prism bar 2 is respectively connected with a rib
Mirror so that one of prism to 1 center of circle of anchor ear line and another prism to 1 center of circle of anchor ear line be right angle.
The top of prism bar 2 is equipped with annular groove to correspond to the interface of prism, convenient for prism to be connected to the top of prism bar 2.
Using the utility model measurement king-post coordinate when, from one of prism measurement king-post along bridge to coordinate value,
The coordinate value of another prism measurement king-post direction across bridge can be obtained king-post in conjunction with the auxiliary of the measuring instruments such as total station
D coordinates value.
