A fixing protection device used for fixing a plug pin and preventing sundries from being clamped in is connected in each sliding clamping cover. The device is provided with the fixing protection device. After the pin is inserted, a movable inclined block is pushed away and a fixed spring is compressed; then the movable inclined block is pushed by the reset fixed spring; and the plug is ejected to realize primary fixation, and then the plug is continuously pushed in and is clamped by a gear fixing block. The situation that the plug is separated from the socket due to shaking is avoided, and when the plug is attached to a contact clamping copper sheet, a stop block is prevented from jacking the plug for further fixation, so that the plug is not easily separated from the copper sheet. Poor contact and other situations are avoided, and the use safety is relatively high.

The invention discloses a carrying and lifting device for mechanical petroleum pipeline installation. The carrying and lifting device comprises a support frame, a transverse frame is installed at theupper end of the support frame, guiding blocks are installed in the middle of the lower end of the transverse frame, a screw is installed in the middles of the guiding blocks, and a driving disc is installed at the left end of the screw; and a first pulling rod is hinged to the lower end of each guiding block, a lifting plate is installed at the lower ends of the first pulling rods, fixing rods are installed on the two sides of the lower end of the lifting plate, a clamping rod is hinged to the bottom end of each fixing rod, a second pulling rod is hinged to the upper end of each clamping rod,a lifting rod is hinged to the upper ends of the second pulling rods, a lifting block is installed in the middle of the lifting rod, a lead screw is connected to the middle of the lifting block through a threaded hole, and a driving motor is connected to the upper end of the lead screw. According to the carrying and lifting device for mechanical petroleum pipeline installation, lifting of petroleum pipelines with different diameters is achieved, left-right waggling generated in the lifting process of the petroleum pipelines is effectively avoided, and then the petroleum pipelines can be precisely delivered to the installing positions; meanwhile, the labor intensity of workers is reduced, the petroleum pipeline laying requirements are met, and the practicability is high.
