Abstract

The utility model provides a tower straightness accuracy measuring tool which characterized in that is including support, scale and fixing device, support and scale are fixed on the tower that awaits measuring through fixing device, placed laser emitter on the support, laser emitter places towards the scale, makes the laser projection point of laser emitter transmission drop on on the scale. Adopt the utility model discloses a tower straightness accuracy measuring tool can avoid utilizing laser emitter because of the error that self drawback of the steel wire of traditional measuring tool or cotton thread leads to, and economy is convenient, and the flexible operation is simple, and the accuracy is high.

Description

Tower straight line degree measuring tool
Technical field
The utility model belongs to device fabrication and field of measuring technique and in particular to a kind of tower straight line degree measuring tool.
Background technology
During design tower, tower body linearity all has clear and definite technical requirements, and the deviation of linearity is to the intensity of tower, stable Property, secure context etc. all have a significant impact.Traditional tower straight line degree measuring tool includes steel wire measurement, cotton thread measurement etc., but Itself all there is drawback in these metering systems, steel wire can be sagging because conducting oneself with dignity, and cotton thread is difficult to pull into straight line because of elasticity, can cause Measurement is inaccurate, the accuracy of impact unit check.
Content of the invention
For overcoming the defect of prior art presence, the utility model provides a kind of tower that measurement is accurate, operation is succinct Straight line degree measuring tool.
For realizing above-mentioned technical purpose, the utility model adopts the following technical scheme that:
A kind of tower straight line degree measuring tool, including bearing, scale and fixing device;Described bearing and scale pass through to fix Device is fixed on tower to be measured;Generating laser is placed with bearing, generating laser is placed towards scale, makes Laser emission The laser projection point of device transmitting falls on scale.
As of the present utility model further preferably, described fixing device is sucker.Described sucker selection can meet difference The powerful electromagnetic chuck of surface quality requirements.
As of the present utility model further preferably, described generating laser is fixed on bearing.Generating laser is fixed On bearing, can achieve the straight line degree measurement of upright tower.
As of the present utility model further preferably, described survey tool carries out adjustment before use, by bearing and scale It is fixed in same level by fixing device, the vertical range of generating laser laser emission point to tower to be measured and scale Upper laser projection point is equal to the vertical range of tower to be measured.
As of the present utility model further preferably, described bearing is provided with scale, and scale lower end is concordant with rest base. On bearing arrange scale, can conveniently further look at regulation, determine laser emission point and subpoint to tower to be measured vertical away from From equal.
As of the present utility model further preferably, described generating laser is the instrument including Laser emission function. For realizing the multiple utilization of field instrumentation, can be selected for laser range finder.
As of the present utility model further preferably, described scale includes fixture and connecting rod;Described fixture is used for fixing sharp Optical transmitting set, described link supports fixture.Preferably, described connecting rod sets rotating shaft, enable 360 ° of rotations of connecting rod.Swashed with meeting The adjustment demand of optical transmitting set.
As of the present utility model further preferably, described scale is embedded in fixing device, makes scale and tower to be measured It is zero graduation standard at contact surface.
Using tower straight line degree measuring tool of the present utility model, can avoid because the steel wire of conventional gauges or cotton thread from The error that body drawback leads to, using generating laser, economical convenient, flexible operation is simple, and accuracy is high.
Brief description
Fig. 1 is the tower straight line degree measuring tool structural representation of the utility model embodiment 1.
Fig. 2 is the seat structure schematic diagram of the tower straight line degree measuring tool of the utility model embodiment 1.
Specific embodiment
Embodiment 1
As shown in figure 1, a kind of tower straight line degree measuring tool, including bearing 2, scale 3 and fixing device 4;Described bearing 2 It is fixed on tower 5 to be measured by fixing device 4 with scale 3;Scale 3 is embedded in fixing device 4, makes scale 3 and tower to be measured It is zero graduation standard at device 5 contact surface;As shown in Fig. 2 bearing 2 structure includes fixture 21 and connecting rod 22, two arrange rotating shaft on the bank Connecting rod 22 is made to be capable of 360 ° of rotations;Generating laser 1 is fixed with fixture 21, generating laser 1 is put towards scale 3 Put, so that the laser projection point that generating laser 1 is launched is fallen on scale 4.
Survey tool carries out adjustment before use, and bearing 2 and scale 3 are fixed on same level by fixing device 4 On, the vertical range of generating laser 1 laser emission point to tower 5 to be measured and laser projection point on scale 3 are to tower 5 to be measured Vertical range is equal.Place the tool above afterwards and move on tower to be measured, measure the skew of subpoint every a segment distance, finally Tower linearity is calculated after counting each side-play amount.
The fixing device 4 selected in the present embodiment is sucker.
Generating laser 1 in the present embodiment is from the laser range finder including generating laser.
Embodiment 2
Embodiment 2 be the difference is that only with embodiment 1, and described bearing is additionally provided with scale, scale lower end and bearing Bottom is concordant.Regulation can conveniently be further looked at, determine that the vertical range of laser emission point and subpoint to tower to be measured is equal.
