Background technology
When the supervisory system of installation tap water, rock gas, heat distribution pipeline, need to measure the radian of pipeline, so that make monitor data more accurate.Particularly when monitoring the parameters such as the water percentage in tap water quality, natural gas line, pipeline radian is significant as the basic data calculated.But large diameter pipeline is difficult to ensure due to the large manufacturing accuracy of volume, brings larger difficulty to follow-up monitoring.Therefore, the first step of installing monitoring sensor measures the radian of this Sensor monitoring pipeline.
Prior art generally adopts the methods such as radius caliper method, common slide calliper rule, arc caliber rule, measurement of coordinates, the high chord length of bow to measure, but degree of accuracy is low, difficulty of construction large, efficiency is not high.At present, rely on grating to carry out the arc measurement device measured although also exist, it could be measured after needing support to fix, and efficiency is low, is not easy to operate.
Utility model content
The utility model object is to provide the arc measurement device of a kind of heavy caliber monitoring pipeline, solves the technical matters that existing arc measurement device degree of accuracy is low, difficulty of construction large, efficiency is not high.
The technical solution adopted in the utility model is: a kind of arc measurement device of heavy caliber monitoring pipeline, comprising:
Surface is provided with the crossbeam of the first indication grating;
The two ends of crossbeam are hinged with the back up pad of circular arc respectively;
Measuring box and crossbeam are slidably connected by horizontal through hole, the inwall of horizontal through hole is provided with corresponding with the first indication grating first and measures grating;
Measuring box is also slidably connected by vertical holes with vertical rod;
The bottom of vertical rod is hinged with measurement pulley by measured hole;
The left and right both ends of the surface measuring pulley are provided with the second indication grating;
The inwall of measured hole corresponds to the second indication grating and is provided with the second measurement grating;
First indication grating, first measures grating, the second indication grating, and second measures grating is all connected with counting circuit, and counting circuit is connected with display.
Further, the top of vertical rod is connected with the inwall of vertical holes by spring.
Further, the outside surface of back up pad is provided with one deck rubber blanket.
Further, display is arranged at the outside surface of measuring box.
Further, counting circuit is also connected with storer.
The utility model provides a kind of heavy caliber to monitor the arc measurement device of pipeline, and operating efficiency is high, is easy to operation, and has higher accuracy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the arc measurement device of a kind of heavy caliber monitoring pipeline in the utility model;
Fig. 2 is the schematic diagram of the measuring box of the arc measurement device of a kind of heavy caliber monitoring pipeline in the utility model;
Fig. 3 is the partial enlarged drawing of the measurement pulley of the arc measurement device of a kind of heavy caliber monitoring pipeline in the utility model.
Embodiment
As shown in Figure 1,2 and 3, a kind of arc measurement device of heavy caliber monitoring pipeline, comprising:
Surface is provided with the crossbeam 3 of the first indication grating 9;
The two ends of crossbeam 3 are hinged with the back up pad 1 of circular arc respectively;
Measuring box 2 and crossbeam 3 are slidably connected by horizontal through hole 10, the inwall of horizontal through hole 10 is provided with corresponding with the first indication grating 9 first and measures grating 11;
Measuring box 2 is also slidably connected by vertical holes 13 with vertical rod 4;
The bottom of vertical rod 4 is hinged with by measured hole 8 measures pulley 5;
The left and right both ends of the surface measuring pulley 5 are provided with the second indication grating 6;
The inwall of measured hole 8 corresponds to the second indication grating 6 and is provided with the second measurement grating 7;
First indication grating 9, first is measured grating 11, second indication grating 6, second measurement grating 7 and is all connected with counting circuit, and counting circuit is connected with display.
The top of vertical rod 4 is connected with the inwall of vertical holes 13 by spring 12.
The outside surface of back up pad 1 is provided with one deck rubber blanket.
Display is arranged at the outside surface of measuring box 2.
Counting circuit is also connected with storer.
During use, the utility model is positioned on the pipeline of needs detection, allows the back up pad 1 at crossbeam 3 two ends abut against on pipeline, meanwhile, measurement pulley 5 is close to pipeline, then horizontally slips.Counting circuit will measure by the first indication grating 9, first chord length that grating 11 obtains sliding path, measure grating 7 and will obtain the arc length slipping over path, then get radian according to the mathematical relation of arc length and chord length by the second indication grating 6, second.
It should be noted that, measurement pulley of the present utility model is single wheel, and compared with two-wheel, accuracy is higher, because can not occur because of the out-of-flatness of duct bottom tilting, causes the different personnel of same place pipeline to measure different data.In addition, the second indication grating 6 that measurement pulley is arranged and the second measurement grating all have 2, can increase the adaptability to rough surface.Counting circuit of the present utility model adopts pure circuit to arrange, with low cost.When manufacturing cost is permitted, it can be replaced with single-chip microcomputer.
The utility model provides a kind of heavy caliber to monitor the arc measurement device of pipeline, and operating efficiency is high, is easy to operation, and has higher accuracy.
Above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
