Problems solved by technology
[0004] The purpose of the present invention is to propose a method that overcomes the problem that the existing electric mechanism is not suitable for the use of small-diameter pipeline robots, so that the driving wheel structure has sufficient positive pressure on the pipe wall to provide stable power when the driving wheel structure is in normal motion; During rescue, reduce positive pressure and friction as much as possible to facilitate rescue and lifting. There is an umbrella-shaped drive wheel structure with state switching between the two

Embodiment Construction
[0016] An umbrella-shaped drive wheel structure is an umbrella-shaped retractable structure, including a tension spring, a tension slider, an umbrella-shaped structure top frame, a main support arm, a secondary support arm, a drive wheel and a wheel frame; The structural top frame is the body of the entire driving wheel structure; one end of the main support arm is riveted with the top frame of the umbrella structure, and the other end hangs the driving wheel and the wheel frame structure; the middle section of the main support arm is riveted with the auxiliary support arm, and the auxiliary support arm The other end is connected with the tensioning slide block; the tensioning slide block can slide on the top frame of the umbrella structure, and a tension spring is arranged between the tensioning slide block and the top frame of the umbrella structure. When the slider moves, the tension spring will give the slider an appropriate restoring force, which will further drive the aux...

The invention relates to a pipe robot, in particular to an umbrella-shaped driving wheel structure for the pipe robot. The umbrella-shaped driving wheel structure is an umbrella-shaped retraction and release structure, and comprises a tension spring, a tension slide block, an umbrella-shaped structure top frame, a main support arm, a secondary support arm, a driving wheel and a wheel frame; the umbrella-shaped structure top frame is a main body of the whole driving wheel structure; one end of the main support arm is connected with the umbrella-shaped structure top frame, and the other end is suspended with the driving wheel and the wheel frame structure; the middle section of the main support arm is connected with the secondary support arm; the other end of the secondary support arm is connected with the tension slide block; the tension slide block can slide on the umbrella-shaped structure top frame; and the tension spring is arranged between the tension slide block and the umbrella-shaped structure top frame. When the slide block moves, the tension spring can give proper return force to the slide block to further drive the secondary support arm to push the main support arm so as to give enough tension force to the driving wheel and the wheel frame.
Description
technical field [0001] The invention relates to a pipeline robot, in particular to an umbrella-shaped driving wheel structure for the pipeline robot. Background technique [0002] Since pipeline robots, especially helical pipeline robots that can adapt to vertical pipelines and horizontal pipelines at the same time, are still in the research and development stage, there are few cases of industrial applications. Therefore, the fault rescue in the actual application process is rarely considered, and a targeted design is carried out. [0003] At present, in the design of the helical robot inside the pipe, due to the electric adjustment mechanism for regulating the positive pressure on the inner wall of the pipe, to a certain extent, the function of facilitating the rescue of the robot has been completed. Because it belongs to the electric mechanism, that is, the driving wheel structure is retracted to the direction of the robot body by means of electric adjustment, so as to co...
