Abstract
The utility model relates to a backup tong power system of hydraulic tongs, which comprises a backup tong main body, a pressurizing oil cylinder, a pressurizing piston assembly, a dual gear and a rack, wherein the pressurizing oil cylinder is installed in the backup tong main body and is internally provided with the pressurizing piston assembly, the pressurizing oil cylinder is contacted with the rack through a piston, and the rack is connected with the dual gear in a transmission manner. The backup tong power system of the hydraulic tongs has reasonable structural design and large power, and effectively improves the working efficiency of the hydraulic tongs.
Description
Technical field
The utility model relates to a kind of hydraulic power system, particularly relates to a kind of hydraulic tongs back-up tong dynamical system.
Background technology
At present, hydraulic tongs mainly is made up of main pincers and back-up tong.Main pincers provide power by Hydraulic Station, through hydraulic motor and gear train transferring power, stable power output are arranged.Compare with main pincers, back-up tong is simple in structure, by Hydraulic Station power is provided, and the oil cylinder transferring power, power output is more less than clamping through rack piston and tail.When running into special circumstances, bigger like the caliber size of tubing string, hardness is high excessively, just cause the back-up tong skidding easily, thereby influenced the operating efficiency of hydraulic tongs.
Summary of the invention
The utility model has overcome deficiency of the prior art, provides a kind of simple in structure, the hydraulic tongs back-up tong dynamical system of high efficiency.
In order to address the above problem, the utility model adopts following technical scheme:
Hydraulic tongs back-up tong dynamical system; Comprise back-up tong main body, pressurizing cylinder, charged piston assembly, duplicate gear and tooth bar, pressurizing cylinder is installed in the back-up tong main body, is provided with the charged piston assembly in the pressurizing cylinder; Pressurizing cylinder contacts with tooth bar through piston, and tooth bar and duplicate gear are in transmission connection.
Compared with prior art, the beneficial effect of the utility model is:
The utility model reasonable in design replaces with pressurizing cylinder with common oil cylinder, and the multiple of supercharging is the ratio of the work area of the big valve piston on the charged piston assembly; Improved power; Increase moment of torsion, the phenomenon of having avoided back-up tong to skid, thus improved operating efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Hydraulic tongs back-up tong dynamical system; Like Fig. 1; Comprise back-up tong main body 1, pressurizing cylinder 3, charged piston assembly 2, duplicate gear 6 and tooth bar 5, pressurizing cylinder 3 is installed in the back-up tong main body 1, is provided with charged piston assembly 2 in the pressurizing cylinder 3; Pressurizing cylinder 3 contacts with tooth bar 5 through piston 4, and tooth bar 5 is in transmission connection with duplicate gear 6.The linear reciprocating motion of tooth bar 5 and piston 4 converts the gyration of duplicate gear 6 into.Because the utility model adopts pressurizing cylinder 3 superchargings, effectively raise power output, increase moment of torsion, thereby improved operating efficiency.
