Abstract
A horsehead pin of a pumping unit with an adjusting sleeve is applied to an oil field beam pumping unit. The adjusting device mainly comprises an inner pin and an adjusting sleeve, wherein the inner pin is mainly a cone, a cylindrical shoulder is arranged at the large-diameter end of the cone, and the inclination of the cone is 3-7 degrees; the inner wall of the adjusting sleeve has the same gradient as the inner pin cone. The adjusting sleeve has an axial gap. When the walking beam type oil pumping machine operates and adjusts the 2 back wearing and tearing of cover, can enlarge horse head round pin adjusting collar external diameter through the inner pin embedding, in time solve the wearing and tearing problem, prolong the life of horse head round pin, ensure the normal operating of oil pumping machine. The oil well production recovery device has the advantages of simple structure, convenience in operation, safety, reliability, reduction in the operation time of replacing the horsehead pin, capability of recovering the production of the oil well as soon as possible, improvement of the production efficiency of the oil well and increase of the crude oil yield.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly the horse head pin on the beam pumping unit is a kind of pumping unit horsehead pin with adjustment sleeve.
Background technique
At present, a large amount of uses of oil field operation is beam pumping unit.The horse head of beam pumping unit is connected with walking beam, the employing that horse head is connected with walking beam be the horse head pin.The horse head pin of existing beam pumping unit is cylindrical, and an end has annular shoulder.In beam pumping unit production run process, the wearing and tearing of horse head pin are recurrent phenomenons.After the horse head pin wearing and tearing of pumping unit, normally move for guaranteeing pumping unit, need to shut down and in time change the horse head pin, the work difficulty of changing the horse head pin is big, and the time is long, delays the oil extraction operation time.Therefore there is the technician to design novel horse head pin,, provides a kind of " pumping unit cammingly horse head pin " as Chinese patent notice of authorization CN2727449; Also have the technician to design the instrument of horse head pin for convenience detach,, provide a kind of " dismounting device of pumping unit horsehead pin " as Chinese patent notice of authorization CN201079944.
Technology contents
The purpose of this utility model provides a kind of pumping unit horsehead pin with adjustment sleeve, be applied to being connected of beam pumping unit horse head and walking beam, after the horse head pin weares and teares, do not dismantle under the situation of horse head pin, can repair wearing and tearing, recover the normal operation of pumping unit.Reduce the time of changing the horse head pin.
The technical solution adopted in the utility model is: the pumping unit horsehead pin of band adjustment sleeve, mainly form by sold inside the country and adjustment sleeve, it is characterized in that: sold inside the country mainly is a cone, and the larger diameter end of cone has cylindrical shoulder, and the gradient of cone is between 3～7 degree; The length of cone (is specifically seen horse head mounting type and horse head width) between 200～400 millimeters.The length of adjustment sleeve is between 200～400 millimeters, and the gradient of adjustment sleeve inwall is identical with the gradient of described sold inside the country cone, and the wall thickness of adjustment sleeve is between 8～10 millimeters.The adjustment sleeve larger diameter end has an annular shoulder.Adjusting is with an axial slits, and axial slits can adopt line to be cut into, or is sawn into hacksaw.
Smaller diameter end at sold inside the country cone has chamfering, and the length of chamfering is 15 millimeters, and the gradient of chamfering is 20 degree; Described adjustment sleeve smaller diameter end is gradient to be the annular cover of 20 degree.
The beneficial effects of the utility model: the pumping unit horsehead pin of the utility model band adjustment sleeve, make former horse head pin sold inside the country and the adjustment sleeve combination, after the wearing and tearing of beam pumping unit operation adjustment sleeve, can enlarge horse head pin adjustment sleeve external diameter by sold inside the country the embedding, in time solve wear problem, prolong the working life of horse head pin, guarantee that pumping unit normally moves.The pumping unit horsehead pin of band adjustment sleeve has simple in structurely, easy to operate, safe and reliable, reduce to change the horse head pin activity duration, and oil well is resumed production as early as possible, and rate when improving oil well production increases crude output, is worth of widely use.
Description of drawings
Fig. 1 is sold inside the country 1 and the pumping unit horsehead pin structure schematic representation of the band adjustment sleeve that is combined into of adjustment sleeve 2.
After Fig. 2 is adjustment sleeve 2 wearing and tearing, with the sold inside the country 1 horse head pin structure schematic representation of pounding the band adjustment sleeve behind the adjustment sleeve 2.
Embodiment
Consult Fig. 1.The pumping unit horsehead pin of band adjustment sleeve, by sold inside the country 1 and adjustment sleeve 2 forms, sold inside the country 1 mainly is a cone, it is 50 millimeters that the larger diameter end of cone has a diameter, thickness is 8 millimeters cylindrical shoulder, the gradient 5 of cone is spent; The length of cone is 250 millimeters.The length of adjustment sleeve 2 is 260 millimeters, and the gradient of adjustment sleeve 2 inwalls is identical with the gradient of described sold inside the country 1 cone, and the wall thickness of adjustment sleeve 2 is 8 millimeters.Adjustment sleeve 2 larger diameter end have an annular shoulder.Adjustment sleeve 2 has an axial slits, and axial slits can adopt line to be cut into.
Smaller diameter end at sold inside the country 1 cone also has chamfering, and the length of chamfering is 15 millimeters, and the gradient of chamfering is 20 degree; Described adjustment sleeve 2 smaller diameter end are gradient to be the annular cover of 20 degree.
Consult Fig. 1.The pumping unit horsehead pin of band adjustment sleeve is installed on the pumping unit, and the distance between sold inside the country 1 the cylindrical shoulder and the annular shoulder of adjustment sleeve 2 is 16 millimeters.Axial slits on the adjustment sleeve 2 is closed up state.
Consult Fig. 2.Behind adjustment sleeve 2 service wears, knock sold inside the country 1 cylindrical shoulder with hand hammer, pound sold inside the country 1 in the adjustment sleeve 2.Dwindle the distance between the annular shoulder of sold inside the country 1 cylindrical shoulder and adjustment sleeve 2.Sold inside the country 1 under the effect of the conical surface, and with the axial slits expansion of adjustment sleeve 2, the external diameter of adjustment sleeve 2 enlarges simultaneously, remedies the wearing and tearing of adjustment sleeve 2.
