The specific embodiment
For further setting forth the present invention, reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to the combination of bindiny mechanism, mast and the unit head of the mast proposing according to the present invention and unit head and there is being described in detail as follows of rotary drilling rig of this combination.
Refer to Fig. 4 to Fig. 6, the bindiny mechanism of mast provided by the present invention and unit head is connected for rotary drilling rig middle mast and unit head, and unit head can be slided along mast.The bindiny mechanism of mast and unit head comprises the guide rail 20 of being located on mast 10 and is located at the hook 40 on unit head 30, hook 40 comprises the connecting portion 41 being connected with unit head 30 and the sliding part 42 being connected with connecting portion 41, connecting portion 41 and sliding part 42 extend along different directions, guide rail 20 is provided with the storage tank 21 extending along the length direction of mast, the sliding part 42 of unit head 30 can slide up and down at mast 10 along storage tank 21, at least one side of guide rail 10, is provided with for connecting some reinforcement structures 50 of mast 10 and guide rail 20.
Particularly, connecting portion 41 and sliding part 42 is mutually vertical, and connecting portion 41 is perpendicular to the main body of unit head 30, sliding part 42 guide rail 20 and unit head 30 during in connection status perpendicular to mast 10.In order to increase the bond strength with unit head 30, at connecting portion 41, near unit head 30 positions, be also provided with matrix part 43, matrix part 43 is one-body molded with connecting portion 41, and mutually vertical with connecting portion 41, and parallel with the main part of unit head 30, by the mode of welding or be spirally connected, be fixed on the main part of unit head 30.
Guide rail 20 is welded in the both sides of mast 10 along the length direction of mast 10, contacting with mast 10 of guide rail 20, two weld seams 11 between surperficial two ends and mast 10, have been formed, on the side deviating from mutually with mast 10 that storage tank 21 is formed at guide rail 20, when sliding part 42 stretches in the storage tank 21 of guide rail 20, in the both sides of guide rail 20, just formed and can hold the accommodation space of strengthening structure 50.The cross section of guide rail 20 can be for U-shaped, C type, the shapes such as dove-tail form, M type, W type or V-type.The shape of the cross section of the shape of sliding part 42 and guide rail 20 adapts, and makes sliding part 42 the interior slip of the length direction along mast 10 can not occur again significantly to rock at the storage tank 21 of guide rail 20.
In the present embodiment, it is spaced some to reinforcing rib along the length direction of mast 10 strengthening structure 50, and one end of reinforcing rib is welded on mast 10, and the other end is welded on guide rail 20, the relatively described guide rail 20 of two reinforcing ribs of each centering is symmetrical arranged, and its cross section is trapezoidal.
As the distortion of reinforcing rib arrangement mode in the present embodiment, strengthening structure 50 also can be for along staggered some the reinforcing rib of mast 10 length directions, and the reinforcing rib that is positioned at adjacent height is positioned at the not homonymy of guide rail 20.Similarly, strengthen structure 50 and also can arrange and be positioned at for the length direction along mast 10 reinforcing rib of guide rail 20 the same sides.
In the present invention, on guide rail 20, be provided with storage tank 21, the mode that three bread in prior art are wrapped up in to guide rail 20 has become the form of sliding part 42 of the storage tank 21 parcel unit heads 30 of guide rail 20, this just provides space for strengthening the laying of structure 50, has improved the area utilization of mast 10 both sides.Strengthening arranging of structure 50 relies on reinforcement structure 50 stressed stressed having become of bindiny mechanism's two weld seams 11 of simple dependence, the stressed weld seam 11 that makes of strengthening structure 50 is converted into merely guide rail 20 is connected to the connective weld on mast 10 by the work weld seam that bears active force, therefore the stress that weld seam 11 places are subject to significantly reduces, and weld seam 11 is not easy cracking.Guide rail 20 and coordinating that sliding part 42 adapts, make unit head 30 reduce vibration when sliding along guide rail 20, reduced further the stress that weld seam 11 is subject to.Make bindiny mechanism of the present invention can bear larger active force.
In sum, by strengthening setting up of structure, make bindiny mechanism provided by the invention reach the object that can bear larger active force.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be not depart from technical solution of the present invention content, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
