Detailed description of the invention
As it is shown in figure 1, a kind of novel tube rod closed power tong includes main pincers and back-up tong, it is connected by contiguous block 4 and pull bar 8 between main pincers and back-up tong.
As depicted in figs. 1 and 2, above-mentioned main pincers include hydraulic system 1, main pincers body 3 and planet linkage I, main pincers body 3 is provided with main pincers upper cover 2, travelling gear 11 is installed between main pincers body 3 and main pincers upper cover 2, main pincers upper cover 2 one end is provided with main pincers end cap 8, main pincers upper cover 2 other end installs hydraulic system 1, it is provided with connecting rod 10 in the middle of main pincers upper cover 2, connecting rod 10 can make Power Tong be positioned on derrick, being provided with planet linkage I inside main pincers body 3, travelling gear 11 is connected with planet linkage I.
As shown in figures 1 and 3, above-mentioned back-up tong includes back-up tong main body 5, back-up tong upper cover 7 and planet linkage II, back-up tong main body 5 upper end is provided with back-up tong upper cover 7, is provided with planet linkage II inside back-up tong main body 5, is connected by hydraulic cylinder 19 between planet linkage II with back-up tong main body 5.
As shown in Figure 2, above-mentioned planet linkage I includes external toothing 11, bearing pin 13 and dental lamina push rod 14, dental lamina push rod 14 is fixed on external toothing 12 by bearing pin 13, dental lamina push rod 14 is provided with guide ring 15, dental lamina push rod 14, under the promotion of external toothing 12, not only can swing around guide ring 15, and relative sliding also can occur with it, in use, footpath can be cut than determine, according to Power Tong, the oil pipe scope that various sizes of dental lamina push rod 14 is suitable for. Within the scope of applicable caliber, it is possible to realize the rotating of oil pipe when being changed without part.
As shown in Figure 3, above-mentioned planet linkage II includes back-up tong planetary 6, dental lamina 16 and connecting rod 17, back-up tong planetary 6 is fixed on planet linkage II, dental lamina 16 is fixed on connecting rod 17, dental lamina 16 is provided with alignment pin 18, can pass through replacing dental lamina 16 in use and connecting rod 17 is applicable to different caliber scopes.
As shown in Figure 4, Figure 5 and Figure 6, dental lamina push rod 14 and the tooth form on dental lamina 16 are all with certain drift angle, and wherein the tooth form of dental lamina 16 push rod is symmetrical.
Operation principle: hydraulic system 1 delivers torque to external toothing 12 by travelling gear 11, external toothing 12 is connected with dental lamina push rod 14 by bearing pin 13, make dental lamina push rod 14 and guide ring 15 that opposing oscillatory and slip to occur, thus realizing dental lamina push rod 14 in two kinds of different directions clamping tube rod counterclockwise and clockwise, complete button and shackle function.
