Problems solved by technology

However, because the detection effect of the former on pressure or tension is greatly affected by the complexity of the pipeline structure and environment, it is difficult to maintain accurate synchronization of the two speeds.

Embodiment 1

[0050] figure 1 A schematic flow chart of a method for synchronously taking up wires of a cable pipeline crawler according to the first embodiment of the present invention is shown.

[0051] The method for synchronously taking up wires of a cable pipeline crawler includes the following steps:

[0052] Step S101 , when the linkage instruction of the crawler and the take-up and take-off vehicle is acquired, the take-up and take-off vehicle is made to take in and out the cable according to the running speed of the crawler.

[0053]The user sends a linkage instruction to the crawler and the take-up and pay-off car through the main control terminal, and the take-up and pay-off car obtains the linkage instruction. Exemplarily, when the take-up and pay-off car receives the linkage instruction, if the crawler moves backward, the take-up and pay-off car takes up the line; if the crawler moves forward, the take-up and pay-off car pays off the line. Optionally, the user can also send a...

Embodiment 2

[0070] figure 2 A schematic structural diagram of a synchronous take-up and take-off device for a cable pipe crawler according to a second embodiment of the present invention is shown.

[0071] The cable pipeline crawler synchronous take-up and pay-off device 200 includes:

[0072] The take-up control module 210 is used to make the take-up and take-off vehicle retract and unwind the cable according to the running speed of the crawler when the linkage command of the crawler and the take-up and take-off vehicle is obtained; the speed acquisition module 220 uses To obtain the line speed of the cable on the take-up and pay-off car; the speed adjustment module 230 is used to compare the driving speed and the line speed, and if the deviation between the two speeds is greater than or equal to a preset deviation threshold, according to the deviation The motor speed of the take-up and pay-off car is adjusted to make the line speed close to the travel speed, so that the deviation betw...

Abstract

The invention discloses a synchronous take-up and pay-off method and device for a cable pipeline crawler and a computer terminal, and the method comprises the steps: enabling a take-up and pay-off vehicle to take up and pay off a cable according to the running speed of the crawler when a linkage instruction of the crawler and the take-up and pay-off vehicle is obtained; acquiring the running speedof the crawler and the linear speed of a cable on the take-up and pay-off vehicle; and comparing the running speed with the linear speed, and if the deviation between the running speed and the linearspeed is greater than or equal to a preset deviation threshold value, adjusting the rotating speed of a motor of the take-up and pay-off vehicle according to the deviation so as to enable the deviation between the linear speed and the running speed to be smaller than the deviation threshold value. According to the technical scheme, the rotating speed of the motor of the take-up and pay-off vehicle is adjusted according to the deviation between the running speed of the crawler and the linear speed of the cable on the take-up and pay-off vehicle, so that the actual take-up and pay-off linear speed of the take-up and pay-off vehicle is kept synchronous with the running speed of the crawler, and smooth implementation of pipeline detection work is guaranteed.

Description

technical field [0001] The invention relates to the field of pipeline detection, in particular to a method, a device and a computer terminal for synchronously retracting and releasing wires of a cable pipeline crawler. Background technique [0002] At present, at home and abroad, most mines, deep wells, municipal pipelines and other places have abnormal conditions, such as blockages and large cracks in sewage and rainwater pipelines. When the pipeline is relatively large, people are usually sent to check it. Dredging; in the case of relatively small pipelines, excavation is generally adopted to repair and solve abnormal situations. In some special cases, such as pipelines, mines, etc., there may be some flammable and explosive gases. If it is difficult to ensure the safety of workers by manual repair, it is easy to cause certain damage to the original structure if it is repaired by excavation. [0003] In view of the above problems, the corresponding pipeline endoscopic cam...
