Background technology
The heavy caliber hole is as the engineering machinery that drills through hole, be widely used in the construction in foundation pouring pile hole and the boring of heavy caliber well of house, highrise building, the dam foundation, port and pier engineering, bridge engineering, have that moment of torsion is big, in light weight, volume is little, intensity is big, borehole accuracy is high, the drilling efficiency advantages of higher.Because boring aperture is big, can reach 1.5-2.0 meters, the driving torque that drilling rod needs is big, the braced structures of unit head (comprising drilling rod) needs will firmly, reliably adopt gantry braced structures that intensity is big, structure is firm usually.Gantry braced structures of prior art, two root posts about mainly comprising, about the lifting gear of unit head and unit head all is arranged between two root posts, about the top of two root posts, be provided with cross-tie with about the top of two root posts link together, form a monolithic construction, to strengthen the strength and stiffness of gantry braced structures.But gantry braced structures of prior art, the deficiency of its existence mainly are that cross-tie and the position between the kelly between two root posts has certain interference, are inconvenient to operate when drilling rod is moved in change owner; In addition, be inconvenient to be provided with the connector of vertical power transmission pole (normally square) on cross-tie, vertical power transmission pole is easy to generate when rotating and rocks, and is not steady when making the work of gantry braced structures and even whole rig, produce certain vibration, reduce the precision of drilling well; Simultaneously, gantry braced structures that two root posts and cross-tie constitute is a plane structure basically, and its strength and stiffness etc. are weakened to a certain extent, reduced the stability of whole rig.
Summary of the invention
The utility model is at the above-mentioned deficiency of prior art rig gantry braced structures, and gantry braced structures of rig stably is provided when not producing location conflicts, rig work between the higher and kelly of a kind of strength and stiffness.
The technical solution of the utility model: gantry braced structures of rig, comprise rig substructure, vertical power transmission pole, drive link supporting seat, rig substructure is provided with left column and right column, and the drive link supporting seat is arranged on vertical power transmission pole top; It is characterized in that: between the top of drive link supporting seat and left column and right column, left connecting rod and right connecting rod are set respectively, left side connecting rod is connected the top of drive link supporting seat and left column, and right connecting rod is connected the top of drive link supporting seat and right column;
At the middle part of left column and right column, left Connection Block and right Connection Block are set respectively, left camber beam bar is set on left Connection Block, right camber beam bar is set on right Connection Block, left camber beam bar is connected through cross bar with right camber beam bar.
Further feature is: left connecting rod and right connecting rod are with respect to the center line symmetry of vertical power transmission pole.
Left side camber beam bar and right camber beam bar are with respect to the center line symmetry of vertical power transmission pole.
Gantry braced structures of the utility model rig with respect to prior art, has following characteristics:
1, being connected between the supporting seat at left and right two root posts and vertical power transmission pole, left connecting rod and right connecting rod are set, make left connecting rod, right connecting rod and left and right two root post tops form a triangular structure, self stability is greatly improved, and improves the stationarity of rig work.
2, left connecting rod, right connecting rod and left and right two root post tops form a triangular structure, significantly improve its strength and stiffness, more help the smooth working of rig.
3, left connecting rod, right connecting rod have been avoided the operating position of kelly, can not interfere by occurrence positions more convenient operation when changing kelly.

The specific embodiment
In Fig. 1,2,3,4, the utility model rig, comprise rig substructure 1, vertical power transmission pole 2, drive link supporting seat 3 and unit head 4, rig substructure 1 is provided with left column 5 and right column 6, vertical power transmission pole 2 rotates under the power set of rig drive, transmission of power to unit head 4, is produced and creeps into power, and unit head 4 is arranged between left column 5 and the right column 6; The top of vertical power transmission pole 2 is provided with drive link supporting seat 3, and rotate in drive link supporting seat 3 on the top of vertical power transmission pole 2; Above as prior art, be not further described at this.
Improvement of the present utility model, be between the top of drive link supporting seat 3 and left column 5 and right column 6, left connecting rod 7 and right connecting rod 8 are set respectively, left side connecting rod 7 be connected drive link supporting seat 3 with the top of left column 5, right connecting rod 8 is connected the top of drive link supporting seat 3 and right column 6, left side connecting rod 7, right connecting rod 8 and left column 5, the top of right column 6 forms triangular structure, left side connecting rod 7, right connecting rod 8 is equivalent to be connected left column 5, the camber beam on right column 6 tops, play the effect that improves its strength and stiffness, more help the smooth working of rig.During concrete the making, drive link supporting seat 3 is arranged on the connecting portion of left connecting rod 7 and right connecting rod 8.
