Description
Technical field
The utility model relates to the brill mast braced structures of rotary drilling rig.
Background technology
The brill mast braced structures of existing rotary drilling rig has two kinds: a kind of for bore mast up and down the hinge close together be called for short the little three-legged structure of parallelogram, this kind structure rig fast rotation and carrying bore when boring mast rock severe especially, poor stability; Also has a kind of brill mast big three-legged structure of hinge distance abbreviation far away up and down, this kind structure rig good stability, but present big three-legged structure bores mast or can not fall backward voluntarily, must utilize auxiliary crane gear to bore mast during transportation and diagonal brace is pulled down, it is the time-consuming expense that increases again, the diagonal brace oil cylinder stroke is too big, is difficult for arranging.In addition, the brill mast verticality on the existing rotary drilling rig can't be adjusted, and the quality of pore-forming can't guarantee, is badly in need of improving.
Summary of the invention
The purpose of this utility model provides a kind of mechanism that is used to regulate rotary drilling rig brill mast angle, solve the too big technical problem of diagonal brace oil cylinder stroke on the big three-legged structure brill mast that can play frame voluntarily and fall; And the problem that can not adjust of the brill mast verticality on the solution rotary drilling rig.
For achieving the above object, the utility model adopts following technical scheme: a kind of mechanism that is used to regulate rotary drilling rig brill mast angle, comprise platform, be fixed on the pivoted arm on the platform, and the brill mast that pivoted arm is hinged and be connected platform and bore diagonal brace oil cylinder between the mast, it is characterized in that: there is one section rear slide at the back side of described brill mast, balladeur train after slidely connecting one on the rear slide, an auxiliary cylinder is arranged, its a end is articulated on the balladeur train of back, the other end is articulated in and bores on the mast, described diagonal brace oil cylinder is divided into two of left diagonal brace oil cylinder and right diagonal brace oil cylinders, left side diagonal brace oil cylinder and right diagonal brace oil cylinder are symmetrically distributed in the both sides of auxiliary cylinder, the motion end of left side diagonal brace oil cylinder is hinged with the back balladeur train, the left side of fixed end and platform is hinged, and the motion end of right diagonal brace oil cylinder is hinged with the back balladeur train, the right side of fixed end and platform is hinged.
Boring mast is ball pivot with the diagonal brace oil cylinder with the hinge of platform with the hinge of pivoted arm and is connected with hinge, the brill mast of diagonal brace oil cylinder.
The forward leaning angle of described brill mast≤5 °, hypsokinesis angle≤90 °, left-leaning angle and Right deviation angle all≤8 °.
Compared with prior art the utlity model has following characteristics and beneficial effect: the utility model is a kind of big gusseted structure that can play frame voluntarily and fall the brill mast, can satisfy rig transition transportation and bore the requirement that mast can fall backward voluntarily, save time and expense, convenient transportation, also shortened the stroke of diagonal brace oil cylinder simultaneously greatly.Compare with the little gusseted structure of existing parallelogram, the stability when the utility model has improved rig work greatly, when having simple in structure, good rigidly, fast rotation and when creeping into good stability advantage.Described diagonal brace oil cylinder is divided into two of left diagonal brace oil cylinder and right diagonal brace oil cylinders, boring mast simultaneously all adopts ball pivot to be connected with the diagonal brace oil cylinder with the hinge of platform with the hinge of pivoted arm with hinge, the brill mast of diagonal brace oil cylinder, so bore the verticality of mast in the time of can adjusting work, guarantee the quality of pore-forming.

The utility model is described in more detail below in conjunction with accompanying drawing.
Fig. 1 is a main TV structure schematic diagram of the present utility model.
Fig. 2 is that schematic diagram is looked on the right side of Fig. 1.
Fig. 3 is the angular adjustment process schematic diagram that bores mast.
Balladeur train, 3-auxiliary cylinder, 4-left side diagonal brace oil cylinder, the right diagonal brace oil cylinder of 5-, 6-platform, 7-bore the hinge of mast and diagonal brace oil cylinder, hinge, 10-rear slide, the 11-pivoted arm that 8-bores hinge, 9-diagonal brace oil cylinder and the platform of mast and pivoted arm behind Reference numeral: 1-brill mast, the 2-.
The specific embodiment
Embodiment is referring to Fig. 1, shown in Figure 2, this mechanism that is used to regulate rotary drilling rig brill mast angle, comprise platform 6, be fixed on the pivoted arm 11 on the platform, and the brill mast 1 that pivoted arm 11 is hinged and be connected platform and bore diagonal brace oil cylinder between the mast, there is one section rear slide 10 at the back side of described brill mast 1, balladeur train 2 after slidely connecting one on the rear slide 10, an auxiliary cylinder 3 is arranged, its a end is articulated on the balladeur train 2 of back, the other end is articulated in and bores on the mast 1, described diagonal brace oil cylinder is divided into left diagonal brace oil cylinder 4 and 5 two of right diagonal brace oil cylinders, left side diagonal brace oil cylinder 4 and right diagonal brace oil cylinder 5 are symmetrically distributed in the both sides of auxiliary cylinder, the motion end of left side diagonal brace oil cylinder 4 is hinged with back balladeur train 2, the left side of fixed end and platform 6 is hinged, and the motion end of right diagonal brace oil cylinder 5 is hinged with back balladeur train 2, the right side of fixed end and platform 6 is hinged.
