Abstract
The utility model discloses a drill rod lifting device of a rotary excavating driller, which comprises a middle girder, a drill rod amplitude oil cylinder, a drill rod and a supporting rod, wherein a hinging point between the drill rod amplitude oil cylinder (2) and the middle girder (1) and a hinging point between the supporting rod (4) and the middle girder (1) are coaxial. The utility model is a drill rod lifting device of a rotary excavating driller, which has the advantages of simple structure, easy producing and low fabrication cost. The lifting force moment is minor while the drill rod is change to an erecting state from a lying state.
Description
Technical field
The utility model relates to a kind of rotary drilling rig, particularly relates to a kind of rotary drilling rig and bores the mast lifting device.
Background technology
Rotary drilling rig is a kind of pore-creating filling pile construction machinery that is widely used in pile foundation constructions such as highway, railway, highrise building, urban construction.Maneuverability, efficiency of construction height are its main characteristics, and wherein boring the setting of mast and keeping flat is one of important symbol of complete machine maneuverability.The middle frame of the setting of present brill mast and the jib lubbing mechanism that keeps flat, brill mast amplitude oil cylinder, brill mast and pole are adopted four groups of pore structures, adopt the setting of brill mast of this form of structure and the jib lubbing mechanism that keeps flat, owing to bore the influence of mast deadweight and the miscellaneous part that is installed on it such as drilling tool, unit head, drilling rod weight, requirement is big especially by the lifting moment that flat condition changes into upright state.
The utility model content
Technical problem to be solved in the utility model provide a kind of when changing into upright state by flat condition required the less rotary drilling rig of lifting moment bore the mast lifting device.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of rotary drilling rig bores the mast lifting device, be made up of middle frame, brill mast amplitude oil cylinder, brill mast and pole, the pin joint of described brill mast amplitude oil cylinder and described middle frame and described pole are coaxial with the pin joint of described middle frame.
The rotary drilling rig of employing technique scheme bores the mast lifting device, bores flexible the making of mast amplitude oil cylinder and bores mast around middle frame and the hinged centre of gyration motion of brill mast, thereby realize boring the setting of mast or keeping flat.This patent adopts the structure of middle frame, and four groups of pore structures that break traditions are merged into one group of hole for two groups with the pin joint that bores the pin joint of mast amplitude oil cylinder and middle frame and pole and middle frame and form three groups of pore structures.Compare with traditional mechanism, present technique has following characteristics: 1, increased lifting moment, owing to adopted coaxial configuration, the arm of force L of oil cylinder power is increased, thereby has increased lifting moment, has satisfied the strength requirement of upright mast; 2, simplified mechanism, made space layout more reasonable.Because middle frame changes three groups of holes into by four groups of holes, thereby has reduced cost of production, has improved installing space and space allowance, the safety that has improved mechanism kinematic; 3, improved the rigidity of mechanism.The profile of this mechanism middle frame and the layout of inner reinforced plate adopt triangular structure, thereby have made full use of leg-of-mutton stability, and mechanism's rigidity is improved.
In sum, the utility model be a kind of when changing into upright state by flat condition required less and simple in structure, easily manufactured, the cheap rotary drilling rig of lifting moment bore the mast lifting device.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model working state schematic representation;
Fig. 3 is present travel position schematic diagram.
The specific embodiment
Following structure the drawings and specific embodiments elaborate to this utility model.
Referring to Fig. 1 and Fig. 2, rotary drilling rig bores the mast lifting device to be made up of middle frame 1, brill mast amplitude oil cylinder 2, brill mast 3 and pole 4, and the pin joint and the pole 4 of boring mast amplitude oil cylinder 2 and middle frame 1 are coaxial with the pin joint of middle frame 1.
Referring to Fig. 1, Fig. 2 and Fig. 3, bore flexible the making of mast amplitude oil cylinder 2 and bore mast 3, thereby realize boring the setting of mast 3 or keeping flat around middle frame 1 and the 3 hinged centre of gyration D motions of brill mast.This patent adopts the structure of middle frame 1, and four groups of pore structures that break traditions are merged into one group of hole A for two groups and form three groups of pore structures boring the pin joint B of mast amplitude oil cylinder 2 and middle frame 1 and the pole 4 pin joint C with middle frame 1.
Claims (1)
- A kind of rotary drilling rig bores the mast lifting device, comprise middle frame, bore the mast amplitude oil cylinder, bore mast and pole, it is characterized in that: described brill mast amplitude oil cylinder (2) is coaxial with the pin joint of described middle frame (1) with the pin joint and the described pole (4) of described middle frame (1).
