Problems solved by technology
Multiple throttle valves are often adjusted synchronously, which is difficult
The synchronization accuracy is poor, the requirement cannot be met, and the drilling tool is deformed
[0007] In addition, the quick-spin mechanism used is a fixed or frame floating mechanism. The fixed type cannot overcome mechanical interference, and the frame type is not convenient for the removal and assembly of drilling tools.
[0008] In the prior art, the movable tongs are used to walk directly on the bed, and there is mechanical interference and the operation is not stable

Embodiment Construction
[0047] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0048] figure 2 Schematic diagram of the structure; wherein, the punching mechanism 3 and the fixed clamp device 4 are combined into a whole, and are fixedly installed on the guide rail of the bed 1 . The device includes a frame body 12, six clamping cylinders 10 are symmetrically installed in six directions of the frame body 12, and six oil cylinders of the same specification are evenly distributed on the periphery of the drilling tool shell, and under the action of the oil cylinders, the drilling tool is simultaneously and evenly clamped. The case is clamped tight.
[0049]The punching mechanism 3 adopts two symmetrically installed punching oil cylinders 11, and under the action of the punching oil cylinders 11, the frame body 12 of the fixed clamp is pushed to rotate, so as to realize the tightening or loosening of the screw thread of t...

The invention relates to a hydraumatic changer of a screw drill tool which comprises a lathe bed, a fast-spin mechanism, a punching mechanism, a fixed plier device, a moving plier device, a secondary bolster, a draw-off gear, a detection and control system and a hydraulic system, wherein synchronism clamp systems of drill tools of the fixed plier device and the movable plier device are controlledby a speed controller; the speed controller consists of motors with equal flow gears; the bottom of the movable plier device is provided with a driving device and a floating idler wheel assembly, which ensures that the movable plier device walks on a guide rail of the lathe bed; and the fast-spin mechanism is an opening type frame and is provided with a jaw for arranging a friction wheel and driving a shell of the drill tool to rotate in a high speed. The invention has large shackle torsion and wide range of tube diameter, and does not damage the surface of a work piece during setting the shackle; two ends of joints of the work piece can move oppositely to the axial direction during punching; the punching plier can clamp the work piece and carry out releasing the shackle and tightening the shackle; and the fast-spin spinner can spin fast and improve the dismounting efficiency.
Description
technical field [0001] The invention relates to a hydraulic disassembly equipment, in particular to a hydraulic disassembly machine used in the assembly and disassembly work of various screw drilling tools used in oil exploitation and geological exploration. Background technique [0002] When the make-up and break-out torque of threaded pipe string workpieces for petroleum and geology is greater than a certain value, manual disassembly and assembly cannot be performed, so a kind of equipment is urgently needed to complete the work. The required hydraulic disassembly and assembly machine has the characteristics and functions of high automation, large torque for making up and breaking down, wide range of applicable pipe diameters, no slipping when making up and down, no biting the surface of the workpiece, quick turn buckle and tail push-pull, etc. to fully meet this requirement. [0003] The function and performance index of the disassembly machine will directly affect the a...
