360-degree hydraulic dismounting and mounting machine for PDM (positive displacement motor) drill

Abstract

The invention provides a 360-degree hydraulic dismounting and mounting machine for a PDM (positive displacement motor) drill. The 360-degree hydraulic dismounting and mounting machine comprises a lathe bed, a torque wrench and a fixing wrench, wherein the torque wrench and the fixing wrench are arranged on the lathe bed; the fixing wrench is movably arranged on the lathe bed; a chain is fixed on the lathe bed; the fixing wrench comprises a vertical plate and a fixing wrench bracket; an upper traveling wheel and a lower traveling wheel are arranged on the vertical plate; the upper traveling wheel is arranged on the front surface, connected with the lathe bed, of the fixing wrench; the lower traveling wheel is arranged on the lower surface, connected with the lathe bed, of the fixing wrench, the fixing wrench bracket is arranged on the vertical plate; a trepanned hole is formed in the center of the fixing wrench bracket; a plurality of oil cylinder positioning plates are arranged on the fixing wrench bracket; every two adjacent oil cylinder positioning plates are oppositely arranged; pin holes are formed in opposite surfaces of every two oil cylinder positioning plates; an oil cylinder is arranged between every two oil cylinder positioning plates, pin holes are formed in the oil cylinders, a pin is arranged between each oil cylinder positioning plate and the pin hole of the corresponding oil cylinder; a chain wheel structure is arranged on the fixing wrench; the chain arranged on the lathe bed penetrates through the chain wheel structure.

Description

technical field [0001] The invention belongs to the technical field of hydraulic dismounting equipment, in particular to a hydraulic dismounting machine for 360-degree screw drilling tools. 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. Therefore, 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 make-up and break-out, wide range of applicable pipe diameters, no slippage during make-up and break-out, no bite on the surface of the workpiece, fast buckle and tail push-pull, etc. to fully meet this requirement. [0003] The function and performance index of the dismantling machine will directly affect the quality of dismounting and operating efficiency of drilling tools. ...

AI Technical Summary

Problems solved by technology

At present, there are two types of dismantling machines, that is, 1 simple type, such as a single-arm punching machine, which only uses a single piece of maintenance. Due to the small function, it is difficult to ensure the assembly quality of the drilling tool, the work efficiency is very low, and the fabric is eliminated.

2. Fully automatic multi-functional disassembly and assembly machine (manufactured by American manufacturers), with high quality drilling tool assembly and high work efficiency. However, due to the low number of equipment exceeding the torque, the scope of application is narrow, especially the high cost and high maintenance cost. Users dare not care about it, which limits the popularization and application of this type of equipment. Therefore, a hydraulic disassembly and assembly with high cost performance and low maintenance cost that can ensure the assembly quality of drilling tools, improve operating efficiency, and greatly reduce manufacturing costs is needed. Urgently needed by users at home and abroad

[0008] At the same time, in the prior art, the punching pliers are driven to rotate through the oil cylinders arranged on the left and right sides, and the driving of the oil cylinder can only be completed by non-stop swinging, resetting and swinging again, and the processing efficiency is extremely low. , the constant swing is also easy to cause the clamping equipment to wear the outer surface of the drilling tool
