Balanced draw gear of municipal administration pipeline sonar check out test set

The utility model provides a balanced draw gear of municipal administration pipeline sonar check out test set, includes: sonar and wireless camera are installed to hull, its front end, thrust unit installs on the hull, and it is used for driving the hull and moves ahead in the pipeline, and the device of crawling, install on the hull, when meetting the place ahead barrier, the device of crawling stretches out from the hull, and thrust unit promotes the hull and crosses the barrier through the device of crawling. When experimental, open thrust unit and making the hull advance the sonar in the pipeline to carry out detection work, when run into the place ahead barrier in the pipeline time, thrust unit stops to promote, and the device of creeping stretches out, and the barrier is crossed to the hull through the device of creeping after, thrust unit promotion hull continues to move ahead to accomplish the experiment work smoothly, effectively improved construction speed, make experimental process operation reliab
