Described spigot surface, guide strip and flashboard body are structure as a whole, and the external diameter of spigot surface, guide strip is consistent with flashboard body diameter.
The guide angle α of described " V " type guide frame is 100 °～145 °.
Between described spigot surface and arc notch, and the matched in clearance of be≤0.3mm between guide strip and bar v notch v.
The advantage the utlity model has and effect:
1, the utility model by arranging two " V " type guide frames and the breach that holds relative two " V " type guide frames on ram block body inner face, and make two " V " type guide frames cover preventer full-bore, realize the comprehensive guiding of cable in the time that ram block body is closed, even also cable reliably can be imported to seal groove when cable bend, thoroughly solve and while closing preventer sealing well head, crushed or the problem of pinch off cable.
2, the utility model V " type guide frame and flashboard body be structure as a whole, and overall Milling Process forms, and intensity is high.In addition after two flashboards cut out, " V " type guide frame coincide with the breach of relative holding of " V " type guide frame, form consistent with the external circle of flashboard and and the identical completely circular structure in flashboard chamber, make V " mutually support and location between type guide frame; further improve the intensity of " V " type guide frame and the operating pressure of bearing, met the reliability of working under superelevation operating pressure 105MPa and even 140MPa.

Detailed description of the invention
Below in conjunction with Fig. 1,2,3,4, a kind of embodiment of the present utility model is described.
A kind of ram block body guide frame, comprises the identical two flashboard bodies 1 of relative motion and structure, and on the inner face of flashboard body 1, has radial groove 2.The inner face projection of described flashboard body 1 has two symmetrical spigot surfaces 3 and two symmetrical guide strips 4, and two symmetrical spigot surfaces 3 and two symmetrical guide strips 4 lay respectively at radial groove 2 both sides; Described two spigot surfaces 3 and two guide strips 4 are alternative arrangement on circumferentially, and is positioned at the spigot surface 3 of radial groove 2 the same sides and the end face of guide strip 4 forms respectively two " V " type guide frames; On the inner face of described flashboard body 1, there are two symmetrical arc notch that hold relative spigot surface 36, and two arc notch 6 lay respectively at the outside of two guide strips 4, and the bottom surface that makes arc notch 6 with hold into spigot surface 3 coincide; On the inner face of described flashboard body 1, there are two symmetrical bar v notch vs 7 that hold relative guide strip 4, and two bar v notch vs 7 lay respectively at the inner side of two spigot surfaces 3, and the bottom surface that makes bar v notch v 7 with hold into the end face of guide strip 4 coincide; Described spigot surface 3, guide strip 4 inner sides all have arc groove 8, and the identical rear relative arc groove 8 of two flashboard bodies 1 forms cable channel 9.
Described spigot surface 3, guide strip 4 is structure as a whole with flashboard body 1, and the external diameter of spigot surface 3, guide strip 4 is consistent with flashboard body 1 external diameter.The guide angle α of described " V " type guide frame is 100 °～145 °.Between described spigot surface 3 and arc notch 6, and the matched in clearance of be≤0.3mm (30) between guide strip 4 and bar v notch v 7.
Wherein, radial groove 2, spigot surface 3, guide strip 4, arc notch 6, bar v notch v 7 and arc groove 8 are all that overall milling completes on the inner face of flashboard body 1, make " V " type guide frame cover preventer full-bore.The seamed edge of described spigot surface 3, the seamed edge of guide strip 4 end faces are all milled into fillet, scratch cable while avoiding leading.Guide angle α is definite according to the stroke of the frictional resistance between cable and spigot surface and flashboard body, and through verification experimental verification, α angle is guide effect the best between 100 °～145 °.
The utility model guide frame and gap structure adopt the matched in clearance of≤30, have both ensured the relative motion of two flashboard bodies, again can be after two flashboards cut out, form and and flashboard chamber identical completely circular structure consistent with the external circle of flashboard.Make V " mutually support and location between type guide frame, further improve the intensity of " V " type guide frame and the operating pressure of bearing, ensure the intensity of guide frame and the reliability of work under superelevation operating pressure 105MPa and even 140MPa.
When the utility model uses, the seal 10 with cable seal groove 5 is embedded to radial groove 2, in the time closing flashboard body 1, make cable can be along the optional position of flashboard body 1 the inner slide into cable channel 9 and enter the cable seal groove 5 of seal 10 end faces through two " V " type guide frames guiding, effectively solve the guiding problem of cable, simple in structure, dependable performance, intensity is high, and cost is low.
Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting the utility model practical range, thus all equivalent variations of being done with content described in the utility model claim, within all should being included in the utility model claim scope.
