Abstract
The utility model discloses a hydraulic bridge type oil-fishing wellhead sealer mainly consisting of a walking beam, a packing, a bearing seat, a packing box, a gland, a support rod and a base. Hydraulic cylinders are respectively arranged on two sides of the packing box and are fixedly mounted on the base; an end of a plunger is hermetically mounted in the hydraulic cylinder; the other end of the plunger passes through the walking beam; a two-way bearing without an inner sleeve is arranged in the bearing seat and on the lower end of the gland. The hydraulic bridge type oil-fishing wellhead sealer has the advantages of simple structure, long service life, low abrasion and high operation efficiency.
Description
Technical field
The utility model relates to a kind of oil mine pore device, especially mainly is the hydraulic bridge type bailing wellhead sealer of walking beam, packing, pressure pad, bearing support, packing box, gland, support bar, base composition.
Background technology
Hydraulic cylinder and the packing box of the hydraulic bailing wellhead sealer of at present well head use are on the same axis, well liquid is easy to enter in the hydraulic cylinder, so that the sand erosion hydraulic part in the well liquid in the application life of having reduced hydraulic part, has increased maintenance cost.The hydraulic bailing wellhead sealer of at present well head use adopts plain bearing, and the wearing and tearing of wire rope and part are comparatively serious, and especially when wire rope bent, it was even more serious to wear and tear, and very inconvenience of the replacing of part has reduced operating efficiency after the wearing and tearing.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, long service life, wearing and tearing are little, operating efficiency is high hydraulic bridge type bailing wellhead sealer.
For achieving the above object, hydraulic bridge type bailing wellhead sealer of the present utility model is mainly by walking beam, packing, pressure pad, described pressure pad is arranged on packing upper end, bearing support, packing box, described packing box is fixedly connected with bearing support with walking beam respectively, gland, described gland is fixedly connected with bearing support on being arranged on bearing support, support bar, described support bar is arranged on the packing lower end, base forms, and hydraulic cylinder is separately positioned on the packing box both sides, is fixedly mounted on the base; Plunger one end is installed in the hydraulic cylinder by sealing cap, and the other end passes walking beam and nut is fixed together; Be arranged in the bearing support without the two-way bearing of inner sleeve, place the gland lower end.
Be comprised of ball, overcoat without the two-way bearing of inner sleeve, leave the gap between the described ball, ball is freely rotating in the two-way bearing without inner sleeve; The diameter of each ball is greater than the maximum value of beeline between two balls that are adjacent, and ball dependence interacts can't be from coming off without the two-way bearing of inner sleeve.
Overcoat is two style structure, is fixedly installed togather behind the built-in ball.
The chamfering of overcoat is 45 °.
The number of ball is for being no less than 3.
After adopting the utility model hydraulic bridge type bailing wellhead sealer, because hydraulic cylinder is separately positioned on the both sides of packing box, hydraulic cylinder and packing box be not on the same axis, well liquid can not enter in the hydraulic cylinder, the wearing and tearing of hydraulic part have been reduced, prolong the application life of hydraulic part, avoided the unnecessary increase of maintenance cost.Chamfering without the overcoat of the two-way bearing of inner sleeve is 45 °, leave the gap between the ball, can guarantee wire rope axially move, when crooked 45 ° of radial motion and wire rope, roller bearing all can freely rotate in the two-way bearing without inner sleeve, so has reduced the wearing and tearing of wire rope and part.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The bailing wellhead sealer of hydraulic bridge type shown in the accompanying drawing, mainly by walking beam 1, packing 3, pressure pad 4, described pressure pad 4 is arranged on packing 3 upper ends, bearing support 7, described bearing support 7 is arranged on pressure pad 4 upper ends, packing box 8, described packing box 8 is fixedly connected with bearing support 7 with walking beam 1 respectively, gland 5, described gland 5 is arranged on bearing support 7 upper ends and is fixedly connected with bearing support 7, support bar 10, described support bar 10 is arranged on packing 3 lower ends and is fixedly connected with joint 17, base 16 forms, hydraulic cylinder 14 is separately positioned on packing box 8 both sides, be fixedly mounted on the base 16, hydraulic cylinder 14 is respectively arranged with up and down upper oil hole 13 and lower oilhole 15; Plunger 9 one ends are installed in the hydraulic cylinder 14 by sealing cap 11, and the other end passes walking beam 1 and is fixed together with nut 2, and sealing ring 12 is installed in the plunger 9; Sealing cap 11 is fixedly connected with hydraulic cylinder 14, and sealing ring 12 is installed in the sealing cap 11; Be arranged in the bearing support 7 without the two-way bearing 6 of inner sleeve, place gland 5 lower ends; Be comprised of ball 19, overcoat 20 without the two-way bearing 6 of inner sleeve, leave the gap between the described ball 19, ball 19 is freely rotating without the two-way bearing of inner sleeve 6 is interior; The diameter of each ball 19 is greater than the maximum value of beeline between two balls 19 that are adjacent, as shown in Figure 4, when all the other balls 19 closely link to each other mutual gapless, beeline reaches maximum value between two balls 19 that are adjacent, and ball 19 dependence interact can't be from coming off without the two-way bearing 6 of inner sleeve; Overcoat 20 is two style structure, is fixedly installed togather behind the built-in ball 19; The chamfering of overcoat 20 is 45 °; The number of ball 19 is for being no less than 3.
During use, fluid enters hydraulic cylinder 14 from the upper oil hole 13 of hydraulic cylinder 14, flow out from lower oilhole 15, promote plunger 9 by hydraulic oil and move downward, plunger 9 drives walking beam 1 and moves downward, because walking beam 1 is with gland 5 with bearing support 7, bearing support 7 with packing box 8, packing box 8 and is fixedly connected with, and then drive pressure pad 4 and move downward, extruding packing 3 under the effect of pressure pad 4 and support bar 10 reaches the purpose of tensioning wire rope 18 and packing box 8, make well head obtain sealing, prevent fluid ejection well head.
