Description

Technical Field

[0001] The utility model relates to the technical field of detection trolleys, and particularly relates to a simple trolley for detecting pipeline welds. Background Technique

[0002] At present, pipeline weld detection is an important link to ensure pipeline safety, mainly involving non-destructive testing of pipeline welds to timely discover and handle potential defects or cracks. If cracks appear in the welds, the inside of the pipeline will rust. In order to judge the rust situation inside the pipeline, staff will use equipment for detection. Detection robots are one of them. Detection robots are usually equipped with cameras, sensors and other related equipment. The robot can enter the pipeline interior, take pictures of the pipeline interior through the camera, and use the sensor to detect the rust degree and corrosion depth of the pipeline wall surface.

[0003] The connection between the camera and the mounting base usually involves multiple components, resulting in cumbersome disassembly and assembly steps. At the same time, some camera connection methods require specific disassembly and assembly tools. If the tools are incomplete, it is difficult to carry out disassembly and assembly, increasing the operation difficulty. Content of the Utility Model

By setting the mounting groove 12 and cooperating with the limiting bolt 13, the camera 3 is placed on the base 1, and the camera 3 is pushed to fit the outside of the baffle 11. At this time, the tool is used to rotate the rotating body 10 to drive the screw 7 to rotate. The screw 7 is composed of two threaded rods with opposite threads. At this time, the screw 7 drives the fixing plate 8 to move until the two fixing plates 8 fit the two ends of the camera 3. At this time, the camera 3 is installed. At this time, a simple detection trolley is assembled. When the base 1 moves in the pipe network, the image inside the pipe network captured by the camera 3 is transmitted to the computer via a data cable. The flashlight 4 provides a light source to enhance the clarity of the image. If the power of the base 1 is exhausted, the base 1 can be pulled out by the traction rope 5 or the traction rope 5 can be pulled to move the base 1. The disassembly and assembly steps of the camera 3 are simple.

[0025] A baffle 11 is fixedly installed on one side of the base 1 close to the camera 3, and a mounting groove 12 is provided on the outside of the baffle 11. The flashlight 4 is slidably connected to the inside of the mounting groove 12 to facilitate the installation of the flashlight 4. One end of the baffle 11 close to the mounting groove 12 is threadedly connected to a limiting bolt 13, and the limiting bolt 13 fits with the outside of the flashlight 4 to strengthen the installation of the flashlight 4.

[0027] Working principle:

[0028] The first step is to set the installation groove 12, cooperate with the limit bolt 13, and insert the flashlight 4 into the installation groove 12.

At this time, place the camera 3 on the base 1, and push the camera 3 to fit the outside of the baffle 11. At this time, use a tool to rotate the rotating body 10 to drive the screw 7 to rotate. The screw 7 is composed of two threaded rods with opposite threads. At this time, the screw 7 drives the fixing plate 8 to move until the two fixing plates 8 fit with the two ends of the camera 3. The camera 3 is fixed to the base 1 through the fixing plate 8, the baffle 11 and the short plate on the base 1. At this time, the camera 3 is installed. The baffle 11 is provided with an opening for the data of the camera 3 to pass through. At this time, a simple detection vehicle is assembled;

[0029] In the second step, bolt 19 is turned to release the connection between bolt 19 and threaded hole 20. At this time, traction rope 5 can be pulled to release traction rope 5. When base 1 moves in the pipe network, the image inside the pipe network captured by camera 3 is transmitted to the computer through data cable. Flashlight 4 provides light source to enhance the clarity of the image. If the power of base 1 is exhausted, base 1 can be pulled out by traction rope 5 or the traction rope 5 can be pulled to move base 1.
