Rotary drilling rig is the construction machinery of drill-pouring common in the present foundation construction, and jib lubbing mechanism is the vitals of rotary drilling rig.It is the critical component that turntable is connected with the brill mast.The stability of rising and falling, boring when unit head is worked mast of boring mast is realized by these parts.Because jib lubbing mechanism is connected with equipment, rig is worked and during the turntable gyration, these parts bear complicated heavy load, and the tendency of distortion and generation fatigue crack is arranged.
The jib lubbing mechanism structure (seeing figure one) of present domestic and international most of rotary drilling rig, tripod 2, connecting rod I 3, turntable 4, connecting rod II 5 constitute parallelogram linkages, and amplitude oil cylinder 6 one ends and turntable 4 are hinged, and the other end and connecting rod II 5 are hinged; It is hinged with tripod 2 to bore mast 1, and it is hinged to play arm hydraulic cylinder 7 one ends and tripod 2, and the other end is hinged with brill mast 1.Under the coordinative role of two kinds of oil cylinders, can be when boring mast and carry out rig work the adjustment of vertical and horizontal direction.Four pin joints are generally arranged on its tripod, and tripod has only three hinges.And essential three pin joints on the turntable 4.The running gear of most of rotary drilling rig is the crawler type chassis special, is universal chassis but not walking mechanisms such as excavator use, poor, the cost of production height of the chassis versatility of rotary drilling rig special use, and maintenance is inconvenient.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of tripod of rotary drilling rig to connect jib lubbing mechanism, increase a pin joint on the tripod, five pin joints are arranged on this tripod like this, be connected with jib lubbing mechanism and only need two pin joints on the turntable of chassis, corresponding two pin joints distance on the distance of these two pin joints and the tripod equates the hinged four-bar linkage structure of formation parallelogram; Also increase a pin joint on the described connecting rod II, luffing hydraulic cylinder one end leads to that pin joint and connecting rod II that bar II go up to increase are hinged, and the other end is hinged by the pin joint and the tripod that increase on the tripod, thus effective operation acts of realization jib lubbing mechanism.Tripod connects jib lubbing mechanism and can be used on the various dissimilar excavator universal chassis, reduces manufacturing cost.Tripod has structurally also been done improvement, improves its intensity, rigidity and reliability.
The utility model is realized with following technical scheme: a kind of tripod of rotary drilling rig connects jib lubbing mechanism, comprising: bore mast, tripod, connecting rod I, connecting rod II, turntable, amplitude oil cylinder, an arm oil cylinder; Described connecting rod I one end is hinged by jointed shaft I and tripod, and the other end is hinged by jointed shaft III and turntable; Described connecting rod II one end is hinged by jointed shaft II and tripod, and the other end is hinged by jointed shaft IV and turntable; Described jointed shaft I, jointed shaft II, jointed shaft III, jointed shaft IV constitute parallelogram linkage; Described tripod is hinged with the brill mast by jointed shaft V, and described arm oil cylinder two ends are hinged with brill mast and tripod respectively; It is characterized in that: jointed shaft VII also is set on the described tripod, on the described connecting rod II jointed shaft VI is set; Described luffing hydraulic cylinder one end is hinged by jointed shaft VI and connecting rod II, and the other end is hinged by jointed shaft VII and tripod.
Good effect of the present utility model is:
1, tripod connection jib lubbing mechanism can be used on the various dissimilar excavator universal chassis, reduces manufacturing cost.
2, tripod structure is reasonable, intensity is high, good rigidity, good reliability, long service life.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the utility model working state structure schematic diagram.
Fig. 2 is the utility model laying state schematic diagram.
Fig. 3 has the jib lubbing mechanism structural representation for event.
Among the figure:
1, bores mast 2, tripod 3, connecting rod I 4, turntable 5, connecting rod II 6, amplitude oil cylinder, 7, play the arm oil cylinder, 8, jointed shaft I, 9, jointed shaft II, 10, jointed shaft III, 11, jointed shaft IV, 12, jointed shaft V, 13, jointed shaft VI, 14, jointed shaft VII.
The specific embodiment
As shown in Figure 1 and Figure 2: a kind of tripod of rotary drilling rig connects jib lubbing mechanism, comprising: bore mast 1, tripod 2, connecting rod I 3, connecting rod II 5, turntable 4, amplitude oil cylinder 6, an arm oil cylinder 7; Described connecting rod I3 one end is hinged by jointed shaft I8 and tripod 2, and the other end is hinged by jointed shaft III10 and turntable 4; Described connecting rod II 5 one ends are hinged by jointed shaft II9 and tripod 2, and the other end is hinged by jointed shaft IV11 and turntable 4.Described jointed shaft I8, jointed shaft II9, jointed shaft III10, jointed shaft IV11 constitute parallelogram linkage.Described tripod 2 is hinged with brill mast 1 by jointed shaft V12, and described arm oil cylinder 7 two ends are hinged with brill mast 1 and tripod 2 respectively.It is characterized in that: also increase on the described tripod 2 jointed shaft VII14 is set, increase on the described connecting rod II 5 jointed shaft VI13 is set; Described luffing hydraulic cylinder 6 one ends are hinged by jointed shaft VI13 and connecting rod II 5, and the other end is hinged by jointed shaft VII14 and tripod 2.Like this tripod 2 respectively with bore mast 1, connecting rod I 3, connecting rod II 5, luffing hydraulic cylinder 6 and play arm hydraulic cylinder 7 hinged, totally five pin joints, thus realize effective operation acts of jib lubbing mechanism.
As shown in Figure 1 and Figure 2: have only two pin joints of jointed shaft III10 and 11, jointed shaft IV between the utility model tripod connection jib lubbing mechanism and the turntable 4, and so there is the jib lubbing mechanism intermediate station that three pin joints are arranged, hinged with connecting rod I 3, connecting rod II 5, luffing hydraulic cylinder 6 respectively.The distance of point-to-point transmission is adjusted than being easier to, and three pin joint adjustment difficulty are very big.So the utility model has very strong compliance to the chassis, can be used on the various dissimilar excavator universal chassis.The cost of production on special-purpose rotary drilling rig chassis is inevitable big, and the chassis of dredging machine cost of producing in batches is low, so this scheme must reduce production costs.
