Abstract
A kind of workover rig winch steel rope live line head locker, comprise compactor, body and slips, it is characterized in that: body is set to cylindrical, top is provided with female thread, female thread bottom is provided with large mouth at upper bell, be provided with two flap-type taper slips in bell, body upper part is provided with the compactor of upper bands fin platform lower bands female thread, is provided with wire rope hole at the center of compactor.The beneficial effects of the utility model: more change steel rope is convenient and swift time saving and energy saving, card steel wire rope head is firm.Significantly improve well workover speed.Effective security risk reduced in replacing live line head process.
Description
Technical field
The utility model relates to a kind of workover rig winch steel rope live line head locker, is a kind of fixing steel wire rope head special mechanism.
Background technology
In Downhole Construction, service machine (tractor hoist) is important well workover weight-lifting equipment, play lower tubular column must apply steel wire large rope derrick crown and trolley block hook are coupled together, need more to renew large rope after the large rope of steel wire uses certain hour, this need of work is frequently with wire clips card live line head, generally take steel rope to draw circle and block 2 rope clips again, take the elasticity that this method is stronger because steel rope has, very easily there is casualty accident, and waste time and energy, poor stability, there is potential safety hazard.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of workover rig winch steel rope live line head locker, can by the live line head of large for steel wire rope, and quick locking is fixed on the mechanism on the winch of service machine.
The technical solution of the utility model is achieved in the following ways:
The utility model comprises compactor, body and slips, it is characterized in that: body is set to cylindrical, top is provided with female thread, female thread bottom is provided with large mouth at upper bell, two flap-type taper slips are provided with in bell, body upper part is provided with the compactor of upper bands fin platform lower bands female thread, is provided with wire rope hole at the center of compactor.
The beneficial effects of the utility model: more change steel rope is convenient and swift time saving and energy saving, card steel wire rope head is firm.Significantly improve well workover speed.Effective security risk reduced in replacing live line head process.
Accompanying drawing explanation
Fig. 1-structural representation of the present utility model
1-compactor, 2 bodies, 3-taper slips in figure.
Detailed description of the invention
For disclosing the technical scheme of the novel type of this reality further, elaborated by embodiment below in conjunction with Figure of description:
The utility model comprises compactor 1, body 2 and taper slips 3, it is characterized in that: body is set to cylindrical, top is provided with female thread, female thread bottom is provided with large mouth at upper bell, two flap-type taper slips are provided with in bell, body upper part is provided with the compactor of upper bands fin platform lower bands female thread, is provided with wire rope hole at the center of compactor.
Current on-the-spot widespread use be that the steel rope way of blocking 2 rope clips again of looping fixes steel wire large rope live line head, although the method for this card wire clips can play the effect of fixing live line head, but it is short that operation field changes the steel wire large rope cycle, change frequent, steel wire large rope diameter is thick, draw the circle of a diameter 100mm, card rope clip again, work is complicated loaded down with trivial details, steel rope elasticity is large, to hurt sb.'s feelings safety misadventure, rope clip is subject to sharp pounding on winch simultaneously, working environment is complicated, the easy back-off of rope clip captive nut, live line head is caused to get loose safety misadventure.Occur that this type of accident is a kind of serious safety misadventure risk to operating personal, equipment etc., reduce work limitation and safety.
The utility model, utilizes taper slips male cone (strobilus masculinus) and intrinsic cone match, and the radial clamping force of motion generation mutually, under the effect of compactor, card steel rope blocks tighter and tighter.Than prior art, more change steel rope is convenient and swift time saving and energy saving, and card steel wire rope head is firm.Significantly improve well workover speed.Effective security risk reduced in replacing live line head process.
