The laser range finder is disposed on the pipeline crawl device and comprises a laser head which can rotate in the range of 360 degrees. The system also comprises a control device which is located outside the pipeline. The control device is connected with the pipeline crawl device and the laser range finder. According to the utility model, the laser range finder which is disposed on the pipeline crawl device is used for annular point scanning of the inner wall of the pipeline. The external control device is used for the collecting connection of a point array which is formed by multiple measurement, thereby forming the pipeline section. The mapping system provided by the utility model is applicable to a pipeline which is deformed in any way. No matter which place of the pipeline the pipeline crawl device is located at, the mapping system can be used for carrying out rotation measurement in the range of 360 degrees through the laser range finder, thereby accurately mapping the sectional view of the interior of the pipeline, which is convenient for a technician to analyze whether there is a deformation defect existing in the pipeline or not.

Background technology
The detection of pipeline is to repair and the prerequisite of reasonable maintenance.The big-diameter pipeline that can enter for personnel, from considering economically, can send the workmen directly to enter inspection record.And, for the unapproachable pipeline of personnel, must adopt additive method.
Using the most general pipe detection instrument now is closed-circuit television (Closed-Circuit Television, CCTV) detection system, is to be specifically applied to the instrument that underground pipeline detects.The CCTV detection system comprises the camera head be loaded on pipe crawling device, and the external control device be connected with camera head with pipe crawling device respectively by cable.Under the instruction that externally control device sends, pipe crawling device is advanced into pipe interior by camera head, then by camera head, takes the pipe interior image, and data are sent to the external control device carry out stores processor.The technician detects video recording according to these, carries out interpretation and the analysis of pipe interior situation, to determine whether pipeline needs to repair and repair to adopt which kind of engineering method, thereby scientifically works out the maintenance scheme.
Whether existing CCTV detection system can only rely on the technician for this fault of construction of pipe deforming amount qualified from the image assessment according to the personal experience, sometimes camera is advanced and is not just being caused image twisted by dirt pollution, image fault, crawl device, just can not accurately judge from image whether pipeline is out of shape, thereby can't know that pipeline is embedded in the underground true strain amount that produced by soil body extruding.
The utility model content
The purpose of this utility model is to provide a kind of pipeline section mapping system, accurately surveys and draws the pipe interior sectional view, avoids existing CCTV detection system to advance and just do not waiting factor to cause artificially judging defect of pipeline due to camera lens pollution, image fault, crawl device.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of pipeline section mapping system, comprise the pipe crawling device and the laser range finder that are positioned at described pipe interior, described laser range finder be loaded on described pipe crawling device and comprise one can 360 the laser head of degree rotation; And the control device that is positioned at described pipeline external, described control device is connected with laser range finder with described pipe crawling device respectively.
The rotational speed of described laser head is constant.
The rotational speed of described laser head be 18 degree/time.
Described laser range finder is positioned on the midline position of described pipeline section.
Described laser range finder is positioned on the non-midline position of described pipeline section.
