The specific embodiment
Core of the present utility model is by setting up the force-bearing situation that support member comes betterment works machinery mast oil cylinder, and reduces its shipping height, flexibility when improving its operation and stability.
Another core of the present utility model provides a kind of engineering machinery that is provided with above-mentioned bracing or strutting arrangement.
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The term in expression orientation such as herein " upper and lower, forward and backward " is based on the position relation of accompanying drawing, it should be interpreted as the absolute qualification to protection domain.
Please refer to Fig. 3, Fig. 3 is the structural representation of a kind of specific embodiment of device that the utility model provides support.
In a kind of specific embodiment, the bracing or strutting arrangement that the utility model provides mainly is made of parts such as mast oil cylinder 10, swing arm 20 and swing arm oil 30.
One end and the mast 40 of mast oil cylinder 10 are hinged, and the other end is hinged by the door frame 70 on hinged seat 60 and the turntable.
Particularly, the lower end of mast oil cylinder 10 and hinged seat 60 are hinged on left and right directions, and hinged seat 60 is hinged on fore-and-aft direction with crossbeam 70-2, and in working order, hinged seat 60 has identical inclination angle in the horizontal direction with mast oil cylinder 10.Like this, can realize mast oil cylinder 10 have about, former and later two degree of freedom, be easy to realize the switching of rig between work and travel position.
This paper does not do qualification to the concrete structure of detent mechanism, and every detent mechanism that door frame can be fixed on the operating position all can be used for realizing the utility model purpose.
For simplified structure, door frame 70 can with swing arm 20 shared same rotating shafts, as shown in the figure, the rotating shaft of the rotating shaft of door frame 70 lower ends and swing arm 20 lower ends is positioned on the same axis, can make full use of installing space limited on the turntable and arrange door frame 70 and swing arm 20.Certainly, under the situation that structural condition allows, also the rotating shaft of door frame 70 and swing arm 20 can be installed separately respectively.
Please refer to Fig. 4, Fig. 4 is that the B of bracing or strutting arrangement shown in Figure 3 is to view.
As shown in the figure, open the lower end of mast oil cylinder 10, form big triangular support structure with the crossbeam 70-2 of door frame 70, and the angle β between the mast oil cylinder 10 is more than or equal to 10 °, the big triangular support structure that angle is bigger, can improve the ability that mast oil cylinder 10 bears moment of torsion, thereby effectively carry the high pulling torque that in the rig course of work mast is produced, improve the problem of rocking that high pulling torque brings.
Please refer to Fig. 5, Fig. 5 is the structural representation of bracing or strutting arrangement shown in Figure 3 when mast is in horizontal travel position.
Above-mentioned bracing or strutting arrangement is as follows from the course of action that horizontal travel position is converted to duty: at first, mast oil cylinder 10 outwards stretches, promote door frame 70 and be rocked to the operating position backward, use bearing pin 90 that door frame 70 and turntable are fixed, after treating that door frame 70 is fixed, mast oil cylinder 10 begins to shrink, and then drive the duty that rotating shaft that mast 40 is hinged around itself and swing arm 20 upwards is raised up to setting, if need further fine setting, then can by rotating disk 50 drive masts 40 about swing in each scope of 6 °, also can realize masts height and the mast adjustment of the radius of gyration in the horizontal direction in vertical direction by swing arm 20.
As shown in the figure, when mast 40 is in running order, door frame 70 is swung lofty perch backward and is fixed by bearing pin 90 and turntable, assist mast oil cylinder 10 to support mast as basic part, thereby under the prerequisite that does not increase mast oil cylinder 10 strokes, improve the hinged bearing height of left and right sides mast rod oil cylinder 10 on mast, improved the force-bearing situation of whole mast and mast oil cylinder 10, can effectively improve the stability of rig and the application life of each component.
When mast 40 is in horizontal travel position, door frame 70 is swing forward on mast 40 directions of motion, its axis of oscillation is parallel with the axis of oscillation of mast 40, finally can be rocked to complete machine peak below, can significantly reduce the shipping height of complete machine, can adjust simultaneously the center of gravity of complete machine under the travel position, improve transportation stability, solve the transportation problem of large-scale engineering machinery.
Certainly, above-mentioned door frame 70 only is a kind of preferred version of support member, and its concrete structure is not limited thereto, and can make pointed adjustment according to the difference of engineering machinery on this basis.Because mode in the cards is more, for saving length, this paper just illustrates no longer one by one.
Except above-mentioned bracing or strutting arrangement, the utility model also provides a kind of engineering machinery, comprises turntable, mast and mast bracing or strutting arrangement, and described mast bracing or strutting arrangement is specially bracing or strutting arrangement mentioned above, and all the other structures see also prior art, and this paper repeats no more.
Be specifically as follows rotary drilling rig, this rotary drilling rig is realized the switchings of mast between travel position and duty by door frame 70 and mast oil cylinder 10, the forward leaning angle of its mast 40 smaller or equal to 90 °, hypsokinesis angle smaller or equal to 15 °.When door frame 70 and turntable relative fixed, its center of gravity and machine gravity are positioned on the same longitudinal axis, stability when well having guaranteed drilling machine construction, when mast 40 is in level, door frame 70 can be swung forward on the direction of motion of mast 40, make the center of gravity reach, help the stability in the rotary drilling rig transportation.
More than bracing or strutting arrangement provided by the utility model and engineering machinery are described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand core concept of the present utility model.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
