Abstract
The invention discloses a jaw structure for an iron roughneck. The jaw structure for the iron roughneck comprises a column; a platform is arranged on the column in the axial direction, the surface of the platform is provided with arc flanges which are distributed at intervals in a staggered mode, and the groove included angle of neighboring flanges is 90 degrees; both ends of the column are provided with semicircular positioning table surfaces, each positioning table surface is provided with an open groove, which faces towards the rim of the column and is disposed on the opposite side of the surface of the platform. The jaw structure for the iron roughneck is novel in structural design, the flanges which are symmetrically distributed on the surface of the platform at intervals can improve the clamping force and stability during the clamping process simultaneously; the positioning table surfaces are provided with the open grooves, so that the positioning and mounting efficiency can be improved; meanwhile, the jaw structure for the iron roughneck has good stability during operation after being mounted.
Description
technical field:
The present invention relates to oil exploration equipment processing, relate in particular to pincers dental structure for a kind of iron driller.
background technology:
Iron driller has been widely used on drilling well working platform as the plant equipment of being responsible for drilling tool handling." iron driller " working portion is general main to be buckled three casings of case and punch oil cylinder etc. and is formed by clamping case, spinner case, punching, and casing adopts Plate Welding frame construction mostly.
Three casings complete respectively relevant operation separately under setting program is controlled, in clamping process, pincers tooth is as one of them assembly, though its structure is little, but play vital effect in the process clamping, mostly there is certain defect in the structure design of pincers tooth at present, can not meet the demand of real work, badly influences efficiency and the quality of work.
summary of the invention:
In order to make up prior art problem, the object of this invention is to provide pincers dental structure for a kind of iron driller, structure design is novel, can meet clamping force and stability in practical work process completely, has improved greatly efficiency and the quality of work.
Technical scheme of the present invention is as follows:
Pincers dental structure for iron driller, comprise cylinder, it is characterized in that: on described cylinder along being provided with platform with axis parallel direction, flat upper surface is provided with interval and stupefied of the arc that is interspersed, groove angle between described adjacent rib is 90 °, described cylinder two ends are provided with semicircular locating table, and locating table is provided with the open slot towards cylinder edge, and open slot is positioned at the offside of flat upper surface.
Pincers dental structure for described iron driller, is characterized in that: the spacing between described adjacent rib top is generally 5.8 ~ 6.2mm.
Pincers dental structure for described iron driller, is characterized in that: described locating table is to the maximum spacing 11.1 ~ 11.3mm at the edge of cylinder.
Pincers dental structure for described iron driller, is characterized in that: described open slot is enlarging shape groove, and bottom is arc.
Pincers dental structure for described iron driller, is characterized in that: the two ends of described cylinder are provided with installing hole along axis direction, installing hole consists of cylindrical hole and bellmouth orifice, and cylindrical hole is positioned at the front end of bellmouth orifice.
Advantage of the present invention is:
1, structure design of the present invention is novel, the rib that symmetric design is interspersed in flat upper surface, and the curved shape of rib, the groove angle between rib is 90 °, has also improved the stability in clamping process when improving clamping force;
2, the present invention is provided with locating platform face at the two ends of cylinder, locating platform face is provided with open slot, the efficiency that has improved location and installed, after installation in working order under, good stability.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
the specific embodiment:
Referring to Fig. 1:
Pincers dental structure for iron driller, comprise cylinder 1, on cylinder 1 along being provided with platform 2 with axis parallel direction, flat upper surface is provided with interval and stupefied 3 of the arc that is interspersed, groove angle between adjacent rib 3 is generally 90 °, has also improved the stability in clamping process when improving clamping force; Cylinder 1 two ends are provided with semicircular locating table 4, and locating table 4 is provided with the open slot 5 towards cylinder edge, and open slot 5 is positioned at the offside of flat upper surface.
Spacing between adjacent rib 3 tops is generally 5.8 ~ 6.2mm.
Locating table 4 is to the maximum spacing 11.1 ~ 11.3mm at the edge of cylinder 1.
The two ends of cylinder 1 are provided with installing hole 6 along axis direction, and installing hole 6 consists of cylindrical hole 6-1 and bellmouth orifice 6-2, and cylindrical hole 6-1 is positioned at the front end of bellmouth orifice 6-2.
