400-1100 Mm X - Ray Pipeline Crawlers 250Kv 17Ah Ndtpipeline Crawler Ndt X Ray Equipment
The basic principle of X-ray pipeline tractor mainly includes
mechanical walking part, ray generation part, positioning sensor,
logic controller, remote power supply and command source, and
positioning outside the pipeline. It is an automatic ray generating
device. The mechanical walking part drives the ray generating
device to move in the pipeline, and the special X-ray film and
label are pasted on the pipe butt weld. Note that through the
cooperation of the remote control device outside the pipeline,
positioning and exposure can be carried out in the pipeline, so as
to carry out X-ray transmission of the pipeline butt girth weld and
realize the non-destructive detection of the pipeline butt girth
weld. In addition, the forward, backward, rest and other actions of
the tractor can also be controlled by the remote control. Dust
control. The pipeline crawler system consists of walking mechanism, visual
inspection device for observing and detecting the inner wall of the
pipe, control and communication device, etc., and repair device for
defects in the pipe can be added if necessary. According to
different application occasions, the robot can be applied to pipe
diameter of 80mm-120mm, 120mm-200mm or larger; The minimum size of
tube defect detection is 0.5×0.5mm. The robot uses dc motor drive
system, the driving force is huge. Can effectively solve pipeline
problems. The hardware design of X-ray pipeline tractor includes: mechanical
walking part, radiation generation part, positioning sensor,
controller (circuit) part, power supply part and automatic
ambulance part. Mechanical part: it is composed of electric body,
charging power body, 24V DC motor, reducer, rubber wheel, axle and
connecting accessories. The whole machine is connected by X-ray
pipeline crawler. Charging power supply car: choose 1mm thick
stainless steel plate, stamping and welding. It is required to have
certain stiffness and is not easy to deform. Install wear resistant
material wheels. The total length is determined by the volume of
the battery. Avoid increasing turning radius, increase
transportation difficulty, the time will not be too long. See
battery Cabling method. Schematic diagram of battery wiring for
X-ray machine (schematic diagram) part: Our proposed design and
interface requirements were handed over to the specialized
manufacturer of X-ray machine. Specific requirements are: DC high
voltage DC power supply, fixed tube voltage 160kV, tube current
3mA, cancel AC/DC part, change the parameters of high voltage
package, provide fault feedback signal, heat dissipation fan
automatically open, automatic delay shutdown as required, to save
power. The console should be small and integrated with the X head.
The structure adopts dustproof design. Localization sensor part:
this problem is basically solved in the gamma-ray track machine
developed successfully in 1997. In order to reduce the complexity
of design, jitter and error can be dealt with in fault-tolerant
programming. Due to the large vibration in the transportation
process, the manufacturing process is required to be higher, the
parts are strictly screened, and anti-vibration measures are taken.
The X-ray pipeline crawlers include the special part that can detect the welding line of long pipeline. The X-ray pipeline crawlers have the advantages of high radiographic quality, high imaging sensitivity, low failure rate and high work efficiency. The X-ray pipeline crawlers have differential driving and vibration absorbers. The chassis of the X-ray pipeline crawlers can be moved in the pipeline steadily without off center running and overturning. The X-ray pipeline crawlers can be moved in the pipeline with great efficiency because it is controlled by PLC with protecting it from blocking and under voltage. The X-ray pipeline crawler is easy to be separated into several parts and then to be put together, so it is easy to carry. You can change the exposure parameter and make the X-ray pipeline crawler move, stop and have an exposure with the exterior controlling source. The X-ray pipeline crawlers are easy to operate.
1 Overview The X-ray Pipeline Crawler is a kind of central radiographic equipments for detecting pipeline welds in long-distance pipeline constructions. The X-ray pipe crawler can be guided into pipes by magnetic locator, and the center of the radiation field can be illuminated at the center of the weld bead. The whole welding joint can be detected in one exposure. Compared with directional radiators, X-ray pipeline crawlers have higher work efficiency but require lower labor intensity. X-ray pipeline crawlers are mainly used in petroleum pipelines, natural gas pipelines, thermal pipelines, etc.
2 Main charateristics 2.1 Unlike controlling the equipments via listening to sounds, manipulators can control the exposure moments and manipulate the X-ray pipeline crawlers to move forward or backward via magnetic orientator. 2.2 Magnetic locators have the following features: higher positional accuracy, strong penetrability, and higher stability. The magnetic transmitter is equipped with electric display. 2.3 The X-ray pipeline crawlers can display the voltage of the battery and directly judge the use of the battery. 2.4 The X-ray pipeline crawlers’ software is written with fault codes. Please refer to the fault code table to detect equipment malfunctions. 2.5 The X-ray pipeline crawler has smaller size, lighter weight, and it is more convenient for transportation and operation. 2.6 Equipped with all kinds of protection functions, including encountering water protection, 20 minutes no one operation protection, etc. 2.7 Users can replace the controller, the circuit board, and other parts easily due to modular design. 2.8 The generator adopts a small 2005 portable circumferential cone target flaw detector: the controller and the head of the machine are separated, which is more convenient for users to replace, debug, and test. If the generator is equipped with the controller, the whole set can be used as a portable flaw detector. 2.9 The crawler is equipped with false load, and the time is set for 0.2 minute. The crawler can simulate the real load working, such as exposure, moving forward or backward without connecting pipe head. This function enable users to learn how to locate and determine the fault. 2.10 The lengthening shaft adopts keyless connection, which is more convenient to replace. 2.11 The magnetic receiver has 8 gear ranges, which satisfy the requirements of different diameters.
