Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 4 The utility model provides a technical solution: an adaptive industrial pipeline internal moving device, including a main body mechanism 1 and a flexible connection mechanism 2, the flexible connection mechanism 2 is located at the front end of the main body mechanism 1, the main body mechanism 1 includes a moving frame 101, an axle 102 and a motor 103, the axle 102 is movably connected to the lower end of the moving frame 101, and the motor 103 is fixedly connected to the left and right ends of the axle 102.

[0025] The main mechanism 1 also includes a transmission shaft 104, a sleeve 105, a roller 106, a crank slider assembly 107 and a return spring 108. The transmission shaft 104 is fixedly connected to the right end of the motor 103, the sleeve 105 is fixedly connected to the outer end of the transmission shaft 104, the roller 106 is fixedly connected to the right end of the sleeve 105, the crank slider assembly 107 is fixedly installed at the lower end of the mobile frame 101, and the return spring 108 is fixedly installed at the left end of the roller 106. The crank slider assembly 107 includes a bearing 1071, a crank 1072, a slider 1073 and a connecting rod 1074. The bearing 1071 is fixedly installed at the lower end of the mobile frame 101, the crank 1072 is fixedly installed at the front end of the bearing 1071, the slider 1073 is movably installed at the outer end of the crank 1072, the connecting rod 1074 is fixedly connected to the right end of the slider 1073, and the connecting rod 1074 is located at the left end of the roller 106.

[0026] The flexible connection mechanism 2 includes a flexible joint 201, a fixing block 202, a fixing hole 203, a bolt washer 204 and a fixing bolt 205. The flexible joint 201 is fixedly installed at the front end of the mobile frame 101, the fixing block 202 is fixedly installed at the upper end of the flexible joint 201, the fixing hole 203 is fixedly arranged at the rear end of the fixing hole 203, the bolt washer 204 is movably connected to the rear end of the fixing hole 203, and the fixing bolt 205 is movably connected to the rear end of the bolt washer 204.

[0027] In this embodiment: the utility model can conveniently detect and clean the pipeline by arranging a mobile frame 101, an axle 102, a motor 103, a transmission shaft 104, a sleeve 105, a roller 106, a crank slider assembly 107, a bearing 1071, a crank 1072, a slider 1073, a connecting rod 1074, a return spring 108, a flexible joint 201, a fixing block 202, a fixing hole 203, a bolt washer 204 and a fixing bolt 205. At the same time, the arrangement of the return spring 108 and the crank slider assembly 107 can adapt to the movement between different pipeline diameters and different diameters in the same pipeline. The flexible joint 201 and the separate motor 103 can ensure that the device maintains balance when turning inside the pipeline, solving the problems that the current cleaning and detection devices inside the pipeline cannot adapt to different pipe diameters; different pipe diameters in the same pipeline; and turning at the pipe connection. The device can effectively cope with the complex environment inside the pipeline, thereby meeting the customer's usage needs.

[0028] Working principle: When the pipeline needs to be inspected and cleaned, the staff can directly put the device into the pipeline. The wheel shaft 102 and the motor 103 can provide power to the device. The motors 103 are equipped at both ends of the wheel shaft 102. The motor 103 drives the device forward or backward through the output shaft. The left and right parts of the device have a set of such configurations to drive different rollers 106 to control the speed, direction or deal with specific obstacles in the pipeline, ensuring that the equipment can adapt to different working environments autonomously, and cooperate with the flexible joint 201 in steering to improve the ability of the machine to pass through different elbows. The transmission shaft 104, sleeve 105 and roller 106 transmit the power of the motor 103 through the transmission shaft 104 The force of the roller 106 is transmitted to the sleeve 105, and then the roller 106 is driven. The roller 106 contacts the pipe wall, so that the mobile device can roll in the pipe. The return spring 108 is responsible for maintaining the stable force of the roller 106 pushing the pipe wall to adapt to the size change of the inner diameter of the pipe and provide a stable friction force to ensure that the mobile device can move closely against the pipe wall in the pipe without sliding. The crank slider assembly 107 can ensure that the roller 106 and the wheel axle 102 are always kept vertical, thereby improving the stability of the device. The structure is simple and the stability is good. A large number of movement cycles can be reliably performed, and the motor 103 is also convenient for accurately controlling the position of the roller 106, thereby ensuring the smooth operation and working efficiency of the device in the pipe. Figure 2 Through the crank slider assembly 107, it can be achieved that when the slider 1073 is located at the far right, the minimum pipe diameter is h = b*sinα, and when the slider is located at the far left, the maximum pipe diameter is h = b*sinβ. It can adapt to different pipe diameters and environments with large changes in pipe diameters in the same pipe. The length of the connecting rod 1074 or the crank 1072 can be adjusted to further adapt to different pipe diameters and environments with large changes in pipe diameters in the same pipe. Through such a design, the mobile device can automatically adjust to conform to the interior of pipes of various sizes and shapes to complete predetermined work tasks, such as inspection, cleaning or repair work.

Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
