Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As depicted in figs. 1 and 2, the utility model provides a kind of horse head pin fixing device.
Particularly, this horse head pin fixing device is used for fixing horse head pin, and horse head pin fixing device comprises ferrule 10 and clamping section 20.Wherein, ferrule 10 has the holding space holding horse head pin, and clamping section 20 is arranged in ferrule 10 to regulate the size of holding space.
Because horse head pin is fixed by ferrule and clamping section acting in conjunction, therefore horse head pin fixing device of the present utility model, structure is simple and can effectively prevent horse head pin from coming off, and avoids the generation of holddown accident, safe and reliable.Also reduce the replacement frequency of horse head pin simultaneously, extend the working life of horse head pin, improve the economic benefit of oil well production.
As shown in Figure 1, the cross section of ferrule 10 in the form of a ring and have the first free end 11 and the second free end 12 of span.In fact, ferrule 10 besieged city has the hollow cylindrical of gap, and horse head pin stretches in this hollow cylindrical to fix horse head pin further.Ferrule 10 besieged city has the hollow cylindrical of gap, and the easy manufacturing of this shape, cost are low, easy to operate, laborsaving.
As shown in Figure 1, clamping section 20 comprises the first clamping section 21, clamping section 21, first and wears and be fixed between the first free end 11 and the second free end 12 for regulating the size of holding space.First clamping section 21 has the structure of the size regulating holding space, and that is the first clamping section 21 can regulate the opening degree of the ferrule 10 of the hollow cylindrical with gap.
As shown in Figure 2, the first clamping section 21 is positioned at the middle part of ferrule 10, and horse head pin is positioned at the top of the first clamping section 21.First clamping section 21 is positioned at the middle part of ferrule 10, and be convenient to the size controlling holding space, it is more easy and stable to regulate, and firm performance is strong.
As depicted in figs. 1 and 2, the first clamping section 21 is arranged along the radial direction of the ferrule 10 of ring-type.The effect of clamping can be better, the size of control holding space of being also more convenient for.
Preferably, the first clamping section 21 comprises clamping bolt 21a and turnbuckle 21b.Clamping bolt 21a wears and is fixed between the first free end 11 and the second free end 12 and along the radial direction of the ferrule 10 of ring-type and arranges, and turnbuckle 21b is fixed on one end of clamping bolt 21a and is positioned at the outside of ferrule 10.Along with the rotation of turnbuckle 21b regulates, make the diameter of ferrule 10 further shrink diminish, holding space diminishes, and makes ferrule 10 pack tightly horse head pin further.
As shown in Figure 1, clamping section 20 also comprises the second clamping section 22, clamping section 22, second for holding out against screw, hold out against screw to be arranged in ferrule 10 and have extend towards holding space hold out against end.Hold out against screw particularly, hold out against screw to be arranged in ferrule 10 and and distance between horse head pin can regulate, hold out against screw have extend towards holding space hold out against end, hold out against end abutting and hold out against horse head pin.
As shown in Figure 2, hold out against screw be positioned at the upper end portion of clamping section 10 and be positioned at the top of the first clamping section 21.Hold out against screw to regulate from the upper end portion clamping of clamping section 10, hold out against better effects if in ferrule 10 for by horse head pin.
Further, hold out against screw to extend along the radial direction of ferrule 10.The effect holding out against horse head pin can be better, and what held out against by horse head pin is also more stable.
As shown in Figure 1, ferrule 10 has the elongated slot 13 coordinated with clamping bolt 21a, and according to the horse head pin of different size, clamping bolt 21a can move to select suitable position to carry out adjustment clamping to ferrule 10 in elongated slot 13.
Preferably, in the present embodiment, the bearing of trend holding out against screw is vertical with the bearing of trend of clamping bolt 21a.Like this for the clamping of horse head pin and the fixed effect that holds out against best.
As can be seen from the above description, the utility model the above embodiments achieve following technique effect:
Because horse head pin is fixed by ferrule and clamping section acting in conjunction, therefore horse head pin fixing device of the present utility model, structure is simple and can effectively prevent horse head pin from coming off, and avoids the generation of holddown accident, safe and reliable.Also reduce the replacement frequency of horse head pin simultaneously, extend the working life of horse head pin, improve the economic benefit of oil well production.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
