Pipeline track acquisition technique is to carry out data acquisition using Pipeline Survey instrument at present, utilizes the spy based on electronic compass
Gauge head calculates three-dimensional track by cable transmission in walking in pipe, by the data of measurement to host computer processing, but passes through cable
It can be disturbed in transmission data procedures by environmental magnetic field, cause bearing data misalignment, measurement accuracy reduces, therefore it is applicable
In the environment of magnetic interference without exception.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of pipeline positioning device, and measurement data is more efficient, essence
It is accurate.
To achieve these goals, the technical solution adopted in the present invention is：
A kind of pipeline positioning device, including front wheels, instrument bin and rear wheels, the instrument bin are tubular structure, and its both ends leads to
Cross central shaft to be connected with front wheels and rear wheels respectively, the front wheels and rear wheels are all circumferentially extending assembly pulley, this two
Wheel group is set and is located at instrument bin on same axis in the same direction, and attitude transducer and wireless device are provided with the instrument bin, should
By the way that the track data of measurement is uploaded by wireless transmission method, the front end of the front wheels is provided with leads attitude transducer
Leading-in device, the attitude transducer are the sensor combined using electronic compass with fibre optic gyroscope.
In said structure, the circumferentially extending assembly pulley includes multiple straightening supports and the wheel being arranged on straightening support
Son, the straightening support include two legs and slip collar, and a leg is be hinged on center shaft, and another leg is hinged on slip
On the collar, the wheel is hinged between two legs, and slip collar covers on center shaft and sets spring to make slip collar by bullet
Power movement drives straightening support circumferentially extending.
Preferably, six straightening supports are respectively provided with the front wheels and rear wheels, detector can be kept before slip
Stability during entering.
Beneficial effects of the present invention：Using the Grid Track of attitude transducer measurement pipeline, based on fibre optic gyroscope technology
The interference of environmental magnetic field can be avoided, in detection process, the straightening support of front and rear two-wheeled group make it that wheel is close with duct wall
Contact, keep detector is stable to move ahead, while there is damping, reduce frictional force；The track data measured passes through
Host computer processing is radioed to, without using data wire, operation is more convenient, is wirelessly transferred that speed is fast, anti-interference energy
Power is strong, so as to draw high accuracy, efficient three-dimensional tube track data in real time.
Brief description of the drawings
