After the technical scheme of this application is adopted, the upper part of the body adopts the connecting axle to fix on main machinery, and flange goes up fixed all kinds of grabs utensil, because rotatory hydraulic fluid port, open on the hydraulic fluid port and closed hydraulic fluid port on link to each other with the hydraulic system on the main machinery, consequently, under main mechanical control, drives the rotation axis rotation in the upper part of the body through rotatory hydraulic fluid port. The opening and closing functions of the gripping apparatus are driven by hydraulic oil, and the gripping apparatus is connected with the rotating shaft in a communicated manner by arranging an oil duct inside the rotating shaft, so that the two-way 360-degree unlimited rotation is realized ingeniously, the problem that the pipeline is not wound is solved, and the problem that the pipeline is wound to be damaged and is limited to rotate in two directions is avoided.
In a further improvement, the upper body comprises an upper shell and a lower shell; the upper shell and the lower shell are fixedly connected with the nut through bolts. The upper part of the body adopts the mode of an upper shell and a lower shell, and the internal rotating shaft is conveniently maintained.
The further improvement is that the top of the upper shell is provided with a fixed seat; the fixing seat is connected with the shaft hole. The fixing seat and the connecting shaft hole are arranged at the top, so that the normal use of the rotator can not be influenced when the fixing seat and the main machine are conveniently connected.
In a further improvement, a handle is fixed on the upper shell through a bolt. Due to the design of the lifting handle, the rotator is convenient to install, maintain and disassemble.
