The utility model discloses a municipal pipe network trenchless cracked pipe repairing system capable of accurately positioning, which comprises a crushing head, guide rods are arranged at the front end and the rear end of the crushing head, the front end of the guide rod on the front side penetrates through a pipe drawing machine fixed in a downstream well, and the pipe drawing machine can pull the guide rod on the front side to move forwards. A new pipe used for replacing an old pipe is arranged at the rear end of the crushing head, the guide rod on the rear side is located in the new pipe, a pipe jacking machine fixed in an upstream well is arranged at the rear end of the guide rod on the rear side, and the pipe jacking machine pushes the guide rod on the rear side and the new pipe to move forwards. A positioning device used for determining the positions of the guide rod and the new pipe is arranged between the guide rod and the rear end of the new pipe, and the positioning device has an adjusting function so that the positioning device can adapt to the new pipes with different pipe diameters. And in the non-excavation cracked pipe repair of the municipal pipe network, not only can the center of the pipeline be prevented from greatly deviating, but also the device can be used for pipe networks with different sizes.

The utility model discloses a crushing head for municipal pipe network non-excavation crack pipe method repair, which comprises a pipe head main body of a frustum with a small front part and a large rear part, a guide connecting rod used for being connected with a guide rod is arranged in the middle of the pipe head main body, and the guide connecting rod and the pipe head main body are coaxially arranged. At least two blades which extend in the diameter direction and are used for breaking an old pipe are arranged outside the pipe head body, and a pipe opening used for being connected with an updated pipeline is formed in the rear end of the pipe head body. The utility model further discloses a system for repairing the municipal pipe network through the non-excavation pipe cracking method. In a municipal pipe network, fracture of old pipes can be effectively achieved, and therefore normal repair is guaranteed.

This utility model relates to the field of steel structure processing technology, specifically disclosing a spraying device for steel structure processing. It includes a worktable, with a moving component at the bottom of the worktable's inner cavity. The moving component includes a second motor located on the left side of the bottom of the worktable's inner cavity. The output end of the second motor has a screw, and a threaded sleeve is threaded onto the surface of the screw. A placement plate is fixedly connected to the top of the threaded sleeve. When spraying a steel structure, the steel plate is first placed on the placement plate. The second motor then operates, driving the screw to rotate, which in turn moves the threaded sleeve, which in turn moves the placement plate. The placement plate is then moved by a sliding groove and slider on the worktable, which in turn moves the steel plate. Simultaneously, a first motor operates, driving a cleaning roller to rotate.
