Abstract
The anti-theft fixing bolt for the balance block of the pumping unit is characterized in that a protective cylinder is arranged at the end part of the fixing bolt, a central hole is formed in the bottom of the protective cylinder, the threaded end of the fixing bolt penetrates through the central hole in the bottom of the protective cylinder, and a nut is connected to the end part of the fixing bolt and is arranged in the protective cylinder; the outer wall of the nut is evenly distributed with strip-shaped bulges. The opening sleeve is cylindrical, the outer diameter of the opening sleeve is the same as the inner diameter of the protection sleeve, the inner diameter of the opening sleeve is the same as the inner diameter of the nut, and strip-shaped depressions are uniformly distributed on the inner wall of the opening sleeve. The top of the opening sleeve is provided with a cylinder, and the cylinder is provided with a transverse hole. The effect is as follows: the weights can be connected together and the nut cannot be loosened without special tools. Effectively reduce or stop the stolen balancing piece material cost and the labour cost that produces of balancing piece, reduce the pumping unit because of the stolen other losses that cause of unbalanced pumping unit of balancing piece increase.
Description
Technical field
The utility model relates to the fixing device of oil-field oil pumper equilibrium block, and particularly the good nut of a kind of fixing bolt of equilibrium block is a kind of balance of well pumping unit piece fixing device with anti-theft feature.
Background technique
At present, the most beam pumping units that adopt in oil well field recover the oil.Pumping unit needs equilibrium block to carry out balance.Existing balance of well pumping unit piece is a blocking type, mostly is irony greatly, and the stolen phenomenon of equilibrium block often takes place no anti-theft device.
Be difficult for being found during the stolen negligible amounts of equilibrium block, really cause the pumping unit imbalance, the waste electric energy increases the pumping unit shock loads, reduces pumping unit working life, increases production cost per tone oil.When the stolen quantity of equilibrium block is more when causing pumping unit serious uneven, pumping unit is by forced-stopping machine, causes burn-down of electric motor when serious even the danger of the machine of turning over is arranged.
The model utility content
The purpose of this utility model is: provide a kind of balance of well pumping unit piece antitheft fixing bolt, use antitheft fixing bolt that equilibrium block is linked together, overcome the stolen deficiency of equilibrium block.
The technical solution adopted in the utility model is: the antitheft fixing bolt of balance of well pumping unit piece, mainly form by fixing bolt 1, protection tube 2, nut 3 and unlatching sleeve 4, there is outside thread the end of fixing bolt 1, it is characterized in that: a protection tube 2 is arranged in the end of fixing bolt 1, center hole is arranged at the bottom of protection tube 2, the threaded end of fixing bolt 1 passes protection tube 2 bottom centre holes, is connected with nut 3 in the end of fixing bolt 1, and nut 3 is in protection tube 2; Described nut 3 is the cylinder bodily form, is evenly distributed with strip bulge on the outer wall of nut 3, and described strip bulge is parallel with the center line of nut 3.With the antitheft fixing bolt of balance of well pumping unit piece equilibrium block is cascaded, because nut does not have special tool not unclamp nut 3 rotations in protection tube 2, so play anti-theft effect.
Described unlatching sleeve 4 is a cylindrical shape; it is identical with protection tube 2 internal diameters to open sleeve 4 external diameters; the internal diameter of opening sleeve 4 is identical with the internal diameter of nut 3, is evenly distributed with the bar shaped depression on the inwall of opening sleeve 4, and described bar shaped depression is parallel with unlatching sleeve 4 center lines.At the top of opening sleeve 4 cylindrical body is arranged, transverse holes is arranged on cylindrical body.Insert from the top of protection tube 2 when opening sleeve 4, and the strip bulge of fixing bolt 1 embeds in the bar shaped depression of opening sleeve 4; Insert cylindrical handle in the transverse holes on opening sleeve 4 cylindrical bodys.Rotatable handle can be tightened nut 3, also nut 3 can be outwarded winding.Do not have corresponding unlatching sleeve 4, can not unclamp nut 3, play antitheft effect.
Strip bulge on described nut 3 outer walls is identical and relative with the quantity that the bar shaped on opening sleeve 4 inwalls is caved in.
The quantity of the bar shaped depression on strip bulge on described nut 3 outer walls and unlatching sleeve 4 inwalls is 3～6.
The beneficial effects of the utility model: the antitheft fixing bolt of the utility model balance of well pumping unit piece can make equilibrium block link together, and not have special-purpose instrument can not unclamp nut.Effectively reduce or stop the equilibrium block material cost and the cost of labour of the stolen generation of equilibrium block, the unknown losses that the pumping unit imbalance that the minimizing pumping unit causes because of equilibrium block is stolen is increased.Processing is simple, and cost is low, and is easy for installation.

Embodiment
Embodiment 1: with an antitheft fixing bolt of balance of well pumping unit piece is example, and the utility model is described in further detail.
Consult Fig. 1.The antitheft fixing bolt of the utility model balance of well pumping unit piece mainly is made up of fixing bolt 1, protection tube 2, nut 3 and unlatching sleeve 4.There is the outside thread of M16 the end of fixing bolt 1.A protection tube 2, the internal diameter 32mm of protection tube 2, external diameter 40mm, height 55mm are arranged in the end of fixing bolt 1.Diameter is arranged at the bottom of protection tube 2 is the center hole of 18mm, and the threaded end of fixing bolt 1 passes protection tube 2 bottom centre holes, is connected with nut 3 in the end of fixing bolt 1, and nut 3 is in protection tube 2.Described nut 3 is the cylinder bodily form, external diameter 19mm.Be evenly distributed with four strip bulges on the outer wall of nut 3, described strip bulge is parallel with the center line of nut 3.
Unlatching sleeve 4 is a cylindrical shape, and it is basic identical with protection tube 2 internal diameters to open sleeve 4 external diameters, and the internal diameter of unlatching sleeve 4 and the internal diameter of nut 3 are basic identical, and the length of opening sleeve 4 is 55mm.Be evenly distributed with four bar shaped depressions on the inwall of opening sleeve 4, described bar shaped depression is parallel with unlatching sleeve 4 center lines.Strip bulge on nut 3 outer walls is identical and relative with the quantity that the bar shaped on opening sleeve 4 inwalls is caved in.At the top of opening sleeve 4 diameter being arranged is the cylindrical body of 18mm, and cylinder height is 22mm.It is the transverse holes of 10mm that a diameter is arranged on cylindrical body.
