Abstract
The utility model relates to an anti-theft anchor block pin which is used for fixing the guy ropes of a well frame in the process of the under well operation of oil water wells. The utility model is composed of a 'T'-shaped screw rod (1), a key (2), a screw cap (3), an anti-theft protection cover (4) and a special spanner (5). The anchor block pin has the functions of preventing disassembly, preventing saw and preventing theft. The anchor block pin has the advantages of simple structure, low cost, etc. The utility model can efficiently prevent the anchor block pin and a turnbuckle losing, preventing the accidents of the collapse of the well frame and the damage of a well opening which are caused by losing the workpieces.
Description
The utility model relates to the Burglar-proof anchor block pin that is used for fixing derrick guy wire in a kind of oil-water well underground work process.
Derrick is the essential equipment of oil-water well underground work.In the underground work process, derrick by guy wire, wire clips, turnbuckle screw, anchor be connected with the earth anchor on ground and fix.At present, because existing ground anchor do not have anti-theft device, and above-mentioned each parts are helicitic texture and connect, and are easy to dismounting, thereby often spot anchor and turnbuckle screw are had things stolen, even cause derrick to collapse and smash accident such as wellhead equipment.
Task of the present utility model is to provide a kind of Burglar-proof anchor block pin, this kind earth anchor elimination can finish outside the linkage function between turnbuckle screw and earth anchor, can also prevent to dismantle privately and steal, thereby prevent losing of ground anchor and turnbuckle screw effectively, prevent that the derrick that therefore causes from collapsing, smashing accidents such as wellhead equipment.
The utility model is to realize like this.It is made up of "T"-shaped screw rod (1), key (2), nut (3), anti-theft protection cover (4) and special spanner (5).Its assembling and architectural feature are: "T"-shaped screw rod (1) polished rod section end is welded with key (2), is set with anti-theft protection cover (4) outside it, and screw rod (1) screw thread position is screwed with nut (3); Other has special spanner (5) to be the aid of dismounting nut (3).During use; anti-theft protection cover (4) being set to the key (2) that makes on the "T"-shaped screw rod (1) on it combines with keyway on protective cover (4) inner headed face; with special spanner (5) nut (3) is screwed into "T"-shaped screw flight position; insert in the symmetrical holes of special spanner (5) with screwdriver at last, nut (3) is tightened.During dismounting, insert with screwdriver in the symmetrical holes of special spanner, nut (3) is unscrewed, twist special spanner with hand and nut (3) can be unloaded.
The utlity model has can prevent dismantling, anti-saw, anti-function of stealing and simple in structure, characteristics such as cost is low, utilize it can prevent losing of ground anchor and turnbuckle effectively, prevent to collapse because of losing the derrick that above-mentioned object causes, oil pumper such as smashes at the generation of accident.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
In the utility model, "T"-shaped screw rod (1) is "T"-shaped, a step is arranged in order to the anti-theft protection cover is played the thrust effect between polished rod section and the spiro rod section, and material is the 45# steel, through Quenching Treatment (playing anti-saw effect); Key (2) material is the A3 steel, is the square toes general flat key, is used to prevent that anti-theft protection cover (4) from rotating; Nut (3) material is the A3 steel, is shaped as standard shape, is of a size of off-standard size, unloads nut or copys special spanner with allen wrench to prevent others; Anti-theft protection cover (4) material A3 steel is through Quenching Treatment, and is cylindrical, and an end internal diameter is less, and is provided with a keyway, and its size and "T"-shaped screw rod polished rod section key that weld the end (2) size match; Special spanner (5) is an allen wrench, and material is the 45# steel, and through normalized treatment, its external surface is the face of cylinder, and an end is made interior six sides, and the other end is evenly equipped with 4 eyelets along periphery, is used to insert screwdriver degree of tightness nut.
