Disclosed is a fast safe solid expandable tube reinforcement device for oilfields. An expander is placed in an expandable patch tube in clearance fit in a broken well casing. The expander comprises a hydraulic tube and a fast inserting rod; the lower end of the hydraulic tube is connected to the upper port of the fast inserting rod, the lower end of the fast inserting rod is embedded in an expandable cone, and the cylindrical portion of the expandable cone tightly matches with the inner wall of an expandable chamber; a lifting rod penetrates the hydraulic tube, the fast inserting rod, the expandable cone in clearance fit from bottom to top, and the lower end of the lifting rod is tightly connected to a combined bottom plug; the combined bottom plug comprises a mandrel, and the mandrel penetrates a piston body, a two-way slip, is embedded in a guide cone holder and is fixedly connected with a pin. The device has the advantages that casing patching operation efficiency is improved greatly, the patching period is shortened, and significant economic benefits can be created. The device is characterized in that after pressing operation of the expandable tube is finished, the expandable cone moves upwardly till the upper port of the expandable tube and drives the lifting rod to move upwardly, the lifting rod drives the combined bottom plug to move upwardly, and the positioning part of the combined bottom plug can reduce automatically to relieve the limit and can be lifted out from the upper end of the expandable tube.

The invention provides a roof damage repairing bracket. The roof damage repairing bracket comprises a transfer box body, a plurality of vertically disposed first guide rails, a plurality of horizontally disposed second guide rails, a processor and a sensor. The multiple first guide rails are arranged around a house in a surrounding mode, and the multiple second guide rails are disposed above a rooftop of the house. The two ends of the second guide rails are correspondingly connected to the first guide rails, and the transfer box body is slidably disposed on the first guide rails and the secondguide rails. The transfer box body is internally provided with a material for repairing a building layer of the house. The sensor is disposed on the side wall of the transfer box body, and the sensoris connected with the processor. A user can store the repairing material in the transfer box body, the occupation of the roof space by the material is saved, the labor intensity of the user is reduced, the repairing work efficiency is improved, the repairing cost is reduced, the intelligentization of house repairing is realized, the installation and maintenance of the repairing bracket by the user are facilitated, and operation and use of the repairing bracket by the user are facilitated.
