Description
Technical field
The utility model relates to field, a kind of oil field, specifically a kind of plait polished rod lifting appliance of more moulting.
Background technology
At present, rod-pumped well hair plait is after fracture, and polished rod and polished rod eye can drop down onto on the packing box, when changing the virgin wool plait, needs usually to use hanging device that polished rod eye is mentioned, and is connected with the virgin wool plait then.This just need employ large-scale hanging device, and waste of manpower, material resources increase maintenance cost.
Summary of the invention
Need employ large-scale hanging device and the deficiency of waste of manpower, material resources in order to overcome the plait of more moulting in the prior art, the utility model provides a kind of plait polished rod lifting appliance of more moulting, and adopts this tool changing hair plait, needn't employ hanging device, save cost, can increase work efficiency.
The technical solution of the utility model is: a kind of plait polished rod lifting appliance of more moulting, comprise upper binding head, lower union joint, be connected by wire rope between upper binding head and the lower union joint, described upper binding head is the cylinder that top board is arranged at inner hollow and top, a cylindrical side has opening, have the draw-in groove of vertical direction on the top board of opening one side, the both sides of draw-in groove connect by safety plug.
Described lower union joint is hair plait head.
The utlity model has following beneficial effect: owing to take such scheme, this lifting appliance utilizes the oil pumper self structure, finishes on the polished rod and carries, and the plait operation that realizes more moulting has avoided employing crane, saves the equipment machine-team, reduces running cost.And this device is applicable to various types, and easy installation and removal is quick, can reduce and wait the equipment time, increases work efficiency, and in time resumes production, and handling safety has been avoided the generation of security incident.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1-upper binding head among the figure, 2-wire rope, 3-lower union joint, 4-safety plug.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, a kind of plait polished rod lifting appliance of more moulting comprises upper binding head 1, lower union joint 3, be connected by wire rope 2 between upper binding head 1 and the lower union joint 3, wire rope 2 for the hair plait be the wire rope of 28mm with thick diameter.Described upper binding head 1 integral body is cylinder, top board is arranged at inner hollow and top, a cylindrical side has opening, the big I assurance hair plait head of opening can be put into, have the draw-in groove 5 of vertical direction on the top board of opening one side, the left and right sides of draw-in groove 5 connects by safety plug 4, and the width of draw-in groove 5 guarantees that hair plait wire rope can pass.Described lower union joint 3 is identical with common hair plait head.
When more moulting plait, the hair plait is put into the lateral openings of upper binding head 1, make mao plait wire rope by passing in the draw-in groove 5, insert good safety plug 4 then, connector 1 is enclosed in the opening, and lower union joint 3 is connected with polished rod eye, starts oil pumper, on carry polished rod, the virgin wool plait can be connected with polished rod eye behind the side's of accomplishing fluently clamp.This lifting appliance at first utilizes the oil pumper self structure, finishes on the polished rod and carries, and the plait operation that realizes more moulting has avoided employing crane, saves the equipment machine-team, reduces running cost.The second, this device is applicable to various types, and easy installation and removal is quick, reduces and waits the equipment time, increases work efficiency, and in time resumes production.Three, do not having under the situation of hanging device, need tie up on virgin wool plait and the polished rod eye with wire rope and carry polished rod, fragile equipment, the personnel that cause injure, there is potential safety hazard, adopts this device and a hair plait, that polished rod eye is connected is firm, handling safety, improve safety factor, avoided the generation of security incident.
