Rod disassembling device assembly

Abstract

The invention provides a rod disassembling device assembly. The rod disassembling device assembly is provided with a rod disassembling supporting seat, a tip seat is installed at the front end of the rod disassembling supporting seat and provided with a tip, and the rod disassembling supporting seat is sequentially provided with a fixed pincer and a movable pincer from front to back; clamping oil cylinders are installed on the two sides of the fixed pincer, and clamping oil cylinders are installed on the two sides of the movable pincer as well; the outer ends of retractable rods of the clamping oil cylinders are each arranged into a clamping jaw shape, and grabbing teeth are separately installed on each clamping jaw; two rod disassembling oil cylinders which are installed in an obliquely-upward mode are installed on the symmetrical positions of the bottoms of the two sides of the movable pincer, and the bottoms of the rod disassembling oil cylinders are hinged to the rod disassembling supporting seat; and a fixed pulley shaft is installed on the position, located on the rear side of the movable pincer, of the rear portion of the rod disassembling supporting seat and provided with a fixed pulley, and the fixed pulley shaft and the fixed pulley are covered with dust covers. According to the rod disassembling device assembly, the structure is simple, installation and using are convenient, and the rod disassembling diameter range is large; clamping force of the clamping oil cylinders is adjustable, the rod disassembling device assembly is suitable for disassembling of rod pieces with different diameters, and the rod disassembling torque is large; and rod disassembling is quick and convenient, grabbing is firmer, and an accident is prevented from occurring.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for anchor drilling rigs, in particular to a rod unloader assembly. Background technique [0002] At the construction site of construction machinery, especially when it involves drilling machinery, it often involves the disassembly and assembly of drill pipes. When loading and unloading drill pipes, clamps are used to clamp and disassemble the drill pipes. On existing machines There are also fixtures for disassembling drill pipes, but most of them have problems such as small diameter range of dismounting drill pipes, insufficient clamping force, and small torque during disassembly. Contents of the invention [0003] The purpose of the present invention is to provide a rod unloader assembly with a large diameter range for unloading rods, firm clamping when unloading rods, and large rotating torque in order to solve the above problems existing in the disassembly and assembly of rods by...
