Abstract
The utility model proposes well head simple and easy control spray oil wiper.Oil wiper comprises large flange, large flange is connected with little flange bolt, step annular groove is had outside large flange centre bore, annular space between the annular groove of large flange and little flange is clamped with rubber flange, large flange, little flange and rubber flange are half-open to assembling structure, the cylindrical interface bolt of large flange connects an axle sleeve of a link, and the another side axle sleeve of link is enclosed within the lock groove of large flange half-and-half; The cylindrical interface welding hinge rank plate of one of them large flange, hinge rank plate has through hole and is connected with the through hole bolt on large flange half-and-half.When not only preventing lift pipe string more than greasy dirt splash to rig floor, cause rig floor wet and slippery, improve the work border of well head operating personnel, decrease potential safety hazard.And effectively control greasy dirt and tripped out tubing string and take high-altitude to and be scattering into derrick, carry on the workover rig such as car and construction plant, reduce construction pollution to greatest extent.
Description
Technical field:
The utility model relates to oil field and executes aid field, is specifically related to well head simple and easy control spray oil wiper.
Background technology:
When workover treatment, most well can not set up circulation canal, removing well head gaslift in process causes rig floor, derrick and well head surrounding enviroment to pollute, and well head operator safety production environment can not get ensureing, the tubing string outer wall greasy dirt stood on rig floor is many, it is wet and slippery that greasy dirt drippage causes rig floor to pollute, well workover industry for many years does not control effectively to the pollution that well head gaslift causes, and frizing uses and scrapes wick, effect extreme difference, impact safety in production, does not reach environmental requirement.
Utility model content:
In order to solve the problem, the utility model is intended to propose a kind of well head simple and easy control spray oil wiper.
The technical solution of the utility model is: well head simple and easy control spray oil wiper, comprise large flange, large flange is connected with little flange bolt, has step annular groove outside large flange centre bore, and the annular space between the annular groove of large flange and little flange is clamped with rubber flange.
Large flange in such scheme, little flange and rubber flange are half-open to assembling structure, and the cylindrical interface of large flange, is, bolt connects an axle sleeve of a link, and the another side axle sleeve of link is enclosed within the lock groove of large flange half-and-half; Another side is, a slice hinge rank plate is respectively welded on the cylindrical interface two sides of one of them large flange, hinge rank plate has through hole and is connected with the through hole bolt on large flange half-and-half.The interface of rubber flange is for smear scarf joint structure mutually, and rubber flange endoporus is conical bore structure, and the endoporus of rubber flange is less than tubing string outside diameter.Large flange periphery has some equally distributed oil-collecting umbrella installing holes.Described lock groove, lock groove is an open type elongated hole, and the size of straight flange distance large flange half opening structure of elongated hole near half-open edge is greater than the size 1.5-2mm of semicircle orifice distance large flange half opening structure.
The utility model has following beneficial effect: it is more than greasy dirt splash to rig floor that this is novel when not only preventing lift pipe string, causes rig floor wet and slippery, improve the work border of well head operating personnel, decrease potential safety hazard.And effectively control greasy dirt and tripped out tubing string and take high-altitude to and be scattering into derrick, carry on the workover rig such as car and construction plant, reducing construction pollution to greatest extent, creating advantage for realizing green construction.

Accompanying drawing 2 is upward views of accompanying drawing 1;
Accompanying drawing 3 is Unclosing structure schematic diagram figure of accompanying drawing 2;
Accompanying drawing 4 is A-A place sectional drawings of accompanying drawing 2.
1-hinge rank plate in figure, 2-large flange, 3-lock groove, 4-chains, the little flange of 5-, 6-rubber flange, 7-oil-collecting umbrella installing hole.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1 composition graphs 2 ~ Fig. 4, well head simple and easy control spray oil wiper comprises large flange 2, large flange 2 is connected with little flange 5 bolt, has step annular groove outside large flange 2 centre bore, and the annular space between the annular groove of large flange 2 and little flange 5 is clamped with rubber flange 6.
Large flange 2, little flange 5 and rubber flange 6 are half-open to assembling structure, and the cylindrical interface of large flange 2, is, bolt connects an axle sleeve of a link 4, and the another side axle sleeve of link 4 is enclosed within the lock groove 3 of large flange 2 half-and-half; Another side is, a slice hinge rank plate 1 is respectively welded on the cylindrical interface two sides of one of them large flange 2, hinge rank plate 1 has through hole and is connected with the through hole bolt on large flange 2 half-and-half.
The interface of rubber flange 6 is smear mutually the rubber flange 6 that scarf joint structure makes to split to form sealing in the plane, the crude oil struck off can not drop from the gap of splitting, rubber flange 6 endoporus is conical bore structure, the endoporus of rubber flange 6 is less than tubing string outside diameter, when oil wiper closes, the endoporus of rubber flange 6 is by tubing string compressive strain, and the cone-shaped inner hole stuck fast column surface of rubber flange 6, strikes off the crude oil on tubing string.
Large flange 2 periphery has some equally distributed oil-collecting umbrella installing holes 7, by oil-collecting umbrella installing hole 7, oil-collecting umbrella is hung over the crude oil collected below oil wiper and strike off.
Described lock groove 3, lock groove 3 is an open type elongated hole, the size of straight flange distance large flange 2 half opening structure of elongated hole near half-open edge is greater than the size 1.5-2mm of semicircle orifice distance large flange 2 half opening structure, the axle sleeve of link 4 is entered in semicircle orifice by the straight flange of lock groove 3 and is lockable, and oil wiper can not be opened in the absence of external forces.
Well head simple and easy control spray oil wiper main body adopts φ 400mm, the steel plate of thick 5mm, and φ 150mm circular hole is cut in centre, and monoblock steel plate is divided into two symmetrical semicircles along axis.Use φ 200mm, the steel plate of thick 5mm, φ 150mm circular hole is cut in centre, is slit into symmetrical two pieces makees pressing plate along axis, with pressing plate by φ 200mm, φ 55mm circular hole is cut in centre, cuts into the rubber tile of two pieces and main body bolt firmly links together along axis, and two pieces of main bodys are hinged, during lift pipe string, simple and easy for well head control spray oil wiper is opened, be buckled on tubing string, lock with lock pin, easy to operate.
