Abstract
The utility model provides a top-drive back-up wrench hydraulic cylinder piston disassembling tool which comprises a base, a fixing pin, a disassembling wrench and pin shafts. The base is provided with an installation pin hole which is matched with and integrally welded with the fixing pin. The disassembling wrench is a long-handle type tool, the head of the disassembling wrench is provided with a round disc, the central hole of the round disc is slightly larger than the outer diameter of the upper portion of a piston rod, the round disc is provided with two pin shafts, and the round disc is connected with the pin shafts and welded with the pin shafts into a whole in a matched mode. Time and labor are saved, a CANRIG top-drive back-up wrench hydraulic cylinder piston and a base of the CANRIG top-drive back-up wrench hydraulic cylinder piston can be conveniently disassembled, all components can not be damaged, and the top-drive back-up wrench hydraulic cylinder piston disassembling tool is simple in structure, practical, economic, and easy to machine and manufacture.
Description
Technical field
The utility model relates to a kind of machine tool, especially a kind of tool special for dismounting that can drive on oil drilling device CANRIG top.
Background technology
At present, in maintenance process is driven on CANRIG top, go back neither one dismounting tong cylinder piston specific purpose tool, the top is driven being connected between tong cylinder piston base and piston and is threaded, in have spring to play damping, cushioning effect; Use procedure at the scene when clamping drilling tool, owing to being subject to huge torsional impact, reaches the corrosion of water, mud, and piston rod and susceptor surface thereof also are smooth cylindrical structure, also brings very large difficulty for detachable maintaining, replacing related elements; Be all to utilize pipe wrench to dismantle in maintenance process, brought damage to parts surface; Also easily cause parts unknown losses in unloading process.
The utility model content
The purpose of this utility model is to avoid the deficiencies in the prior art and the tong cylinder piston disassembling tool is driven on a kind of top of providing.
The technical scheme that the utility model adopts is: the tong cylinder piston disassembling tool is driven on the top, comprises base, steady pin, dismantling spanner, bearing pin; The installation pin-and-hole is arranged on base, coordinate with steady pin and be welded as a whole; Dismantling spanner is a long handle type instrument, and head is with circular discs, and the interstitial hole of circular discs is slightly larger than piston rod top external diameter, and circular discs is with two bearing pins, and circular discs and bearing pin are connected and are welded as a whole.
Match with installing hole on the piston base lower end surface in the external diameter of the steady pin on base, length and position; Match with installing hole on the piston upper end in external diameter, length and the position of two bearing pins on dismantling spanner.
The beneficial effects of the utility model are: can save time, laborsaving, very easily the tong cylinder piston be driven on the CANRIG top and base is dismantled, guarantee that each part is injury-free; The utility model is simple in structure, practical, economical, easily processing and manufacturing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1 is base, and 2 is steady pin, and 3 is dismantling spanner, and 4 is bearing pin.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Drop handle dismounting hinge pin frock is driven on the top, comprises base 1, steady pin 2, dismantling spanner 3, bearing pin 4; Steady pin 2 is high strength pin spare, and the installation pin-and-hole is arranged on base 1, coordinates and is welded as a whole with steady pin 2; Dismantling spanner 3 is a long handle type instrument, and head is with circular discs, and the interstitial hole of circular discs is slightly larger than piston rod top external diameter, and circular discs is with two bearing pins 4, and circular discs and bearing pin 4 are connected and are welded as a whole, proof strength;
Tong cylinder piston base lower end surface and piston upper end are driven all with two process Installation holes in the top; On the external diameter of the steady pin on base 1, length and position and piston base lower end surface, match in two process Installation holes; On external diameter, length and the position of two bearing pins 4 on dismantling spanner 3 and piston upper end, match in two process Installation holes.During dismounting, fix tooling base 1 and namely fix piston base, dismantling spanner 3 is placed on piston top, and bearing pin 4 is in the piston fabrication hole; Rotate dismantling spanner and get final product rotating piston, drive the tong cylinder piston thereby dismantle the top.This frock manufacturing is simple, easy to use, time saving and energy saving, can effectively dismantle various types of seemingly connector, guarantees its dismounting effect.
Claims (2)
