The invention relates to the technical field of
pipe maintenance equipment, in particular, remote
pipe local annular repair equipment and method. The remote
pipe local annular repair equipment comprises a detection mechanism, a repair mechanism, an auxiliary mechanism and two small-size intelligent vehicles. The detection mechanism and the repair mechanism are each arranged on the corresponding small-size intelligent vehicle. Each small-size intelligent vehicle comprises a base plate, a lifting plate, an ascending-and-descending block and a small-size hydraulic rod. One end of each lifting plate is in shaft connection with one end of the corresponding base plate in a matched manner. Each small-size hydraulic rod is mounted at the outer side of the corresponding base plate and used for driving the other end of the corresponding lifting plate to move. A top beam bracket is arranged above each base plate in an erected manner. Each ascending-and-descending block is movably arranged at oneend of the corresponding top beam bracket. The bottom of each ascending-and-descending block is in transmission fit with the free end of the corresponding lifting plate. The detection mechanism comprises a
CCD camera and a light supplementing device, wherein the
CCD camera and the light supplementing device are mounted at the front sides of the ascending-and-descending blocks corresponding to theCCD camera and the light supplementing device. The repair mechanism comprises a first spray head, a second spray head and a third spray head, wherein the first spray head, the second spray head and the third spray head are mounted at the front sides of the ascending-and-descending blocks corresponding to the first spray head, the second spray head and the third spray head. The auxiliary mechanismcomprises a cleaning air bag and a compaction air bag. By means of the remote pipe local annular repair equipment and method, the repair quality can be greatly improved.
