Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
In the present invention, when not doing contrary explanation, the noun of locality of use as " upper and lower, side direction " normally for direction shown in the drawings or for each parts mutual alignment relationship description word vertically, on vertical or gravity direction.Term " center to center distance " in this manual refers in particular to when mast 1 and unit head 2 are in vertical job state shown in the drawings, the minimum spacing between unit head central axis HH ' and mast centre axes O O ' or horizontal range.
As shown in Figure 3, the invention provides a kind of rotary drilling rig, this rotary drilling rig comprises mast 1 and unit head 2, and this unit head 2 is provided with mounting bracket 21, and described mast 1 is provided with balladeur train 11, and specifically, balladeur train 11 is generally set on mast guide rail.In addition, this rotary drilling rig also comprises connection bracket 3, is connected between described balladeur train 11 with described mounting bracket 21 by described connection bracket 3, to regulate the center to center distance size between described unit head 2 and described mast 1.Like this, compared to the rotary drilling rig according to prior art shown in Fig. 2, be no longer directly be connected with mounting bracket 21 by balladeur train 11, but set up connection bracket 3 between mast 1 and unit head 2, the two is linked together indirectly.By this syndeton and mounting means, namely by installation or removal connection bracket 3, the minimum spacing between the mast centre axes O O ' of the in the vertical direction shown in Fig. 3 and unit head central axis HH ' just can be changed, i.e. center to center distance a.As total conception, when the drilling work of large-size, connection bracket 3 can be set up between mast 1 and unit head 2, make operating radius (unit head 2 is away from the radius distance of the centre of gyration body on the creeper truck 6 shown in Fig. 1) become large.And when the drill bit will changing smaller szie carries out operation, then can by changing center to center distance a such as by connection bracket 3 being unloaded, operating radius is diminished, to increase complete machine stability during rotary rig operation, the reaction torque to mast guide rail during reduction operation simultaneously.
See Fig. 3, the installation portion 33 that described connection bracket 3 can comprise connecting pin 31, body 32 and extend from side direction this body 32, this installation portion 33 is provided with the installing hole 34 with described connecting pin 31 adaptation.Installation portion 33, for connection bracket 3 is installed to other device, can have various structures or connected mode to realize.Such as by the connected mode of this connecting pin 31 in present embodiment, just can realize connection bracket 3 and be connected with balladeur train 11 and the stable of mounting bracket 21 respectively.Wherein, preferably there are in every side of described connection bracket 3 at least two described installation portions 33, on the upper end that these two installation portions 33 are respectively formed at described connection bracket 3 and bottom.In every side of connection bracket 3, preferably there are two installation portions 33, this be not only in order to balladeur train 11 and mounting bracket 21 consistent, the stability especially in order to connect.Because when side only has an installation portion 33, according to pinned connection mode, then may form rotatably hinged instead of firmly syndeton.Certainly, also can adopt the installation portion 33 more than two in the side of connection bracket 3, this just needs to set up installing hole matchingly at balladeur train 11 and mounting bracket 21.
In the syndeton of a kind of preferred embodiment as shown in Figure 3, only be provided with a connection bracket 3, namely the adjustable rotary drilling rig of center to center distance comprises a described connection bracket 3, and the side of this connection bracket 3 is connected to described mounting bracket 21, and opposite side is connected to described balladeur train 11.Like this, by the installation or removal of connection bracket with adjusting center distance a, but under this mode, center to center distance only has two kinds of situations, namely sets up the center to center distance after a connection bracket 3 described in the center to center distance after a described connection bracket 3 and removal.But this can meet rotary drilling rig job requirements in the ordinary course of things.
But in order to the center to center distance realizing rotary drilling rig is best adjustable, described installation portion 33 can be provided preferably with the multiple installing holes 34 arranged roughly in the horizontal direction.Like this, just according to the size of required center to center distance a, connecting pin 31 can be connected with balladeur train 11 or mounting bracket 21 through the installing hole 34 on varying level position.Thus, by arranging multiple installing holes 34 of horizontal direction in connection bracket 3, the size by selecting the continuous adjusting center distance a of installing hole 34 can be realized.In this case, increase only a connection bracket 3, do not affect connective stability.Preferably, in order to ensure the soundness of installation portion 33, can take to increase the measures such as its thickness.
Certainly, those skilled in the art should know that various structures form is to realize the continuous adjustment of center to center distance a size in addition.Such as, as the selectable mode of one, can comprise multiple described connection bracket 3 according to rotary drilling rig of the present invention, the plurality of connection bracket 3 connects successively side by side in side direction, as shown in Figure 4 there are 3 described mounting brackets 3.In other words, see Fig. 3, have on the basis of specific width in single connection bracket 3, when the knots modification of center to center distance is larger, by multiple connection bracket 3 each other side direction be connected to form connection bracket group, finally the Far Left of described connection bracket group and rightmost installation portion 33 are connected respectively on balladeur train 11 and mounting bracket 21 by connecting pin 31.Like this, by selecting the number of connection bracket 3, the multiple choices of center to center distance or so-called continuous adjustment can just be realized.But it is too much that the deficiency that this mode exists is connector, and probably have the defect of connective stability and fixing deficiency, those skilled in the art can expect setting up the such as mode such as cross reinforcing or bottom whippletree and strengthen structural stability.In addition; the size of adjusting center distance can also be carried out by the mode of setting up junction plate between the installation portion 33 of connection bracket 3 and balladeur train 11 or mounting bracket 21; this attainable frame mode has multiple; no longer enumerate at this; but generally speaking still belong to arranges in the category of connection bracket between balladeur train 11 and mounting bracket 21, does not depart from protection scope of the present invention.Further, adopt above-mentioned when setting up the mode of junction plate, should be taken into account stability and the fixing problem of syndeton equally.
Below the preferred embodiment of the present invention is described in detail by reference to the accompanying drawings; but; the present invention is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
It should be noted that in addition, each concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the present invention illustrates no longer separately to various possible combination.
In addition, also can be combined between various different embodiment of the present invention, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
