Compared with current technologies, the utility model has advantages of not only avoiding friction and wear between the steel wire rope and a piston rod of a oil cylinder of the mast, but also increasing journal force component of the steel wire rope winding on the drum of the main hoisting device to secure a orderly arranged steel wire rope on the drum and avoid ''rope skipping phenomenon'' and greatly improving useful life of the steel wire rope.
Description
Technical field
The utility model relates to a kind of builing industry foundation construction Work machine, particularly a kind of rotary drilling rig.
Background technology
The lifting of rotary drilling rig drilling rod and the whereabouts of prior art mainly are to realize by the haulage cable that is connected between master winch device reel and the drilling rod.Behind the wire rope jointed rod, walk around the large pulley group of tens meters high mast top, enter the reel of master winch device along mast downwards.Because the large pulley group on mast top and the distance between the master winch device reel reach tens meters; and in mast top and master winch device reel reach tens meters distance between the two; the device that can retrain the wire rope swing is not set, unfavorable phenomenon below therefore regular meeting occurs in operation process:
The one, because of wire rope has goodish pliability on so long distance, can cause significantly swing, the flicker of wire rope on whole mast height, drift, be easy to bump wearing and tearing oil cylinder piston bar with mast oil cylinder;
The 2nd, because wire rope need twine on master winch device reel and two-layerly could satisfy construction requirement, wire rope should be in transverse movement (as shown in Figure 1) between 2 of A, the B on the reel during winding.But because distance is excessive between the large pulley D point on reel and mast top, this just causes the angle β between straight line AD and the BD very little, and general rotary drilling rig β angle is less than 2 °.When wire rope on the reel by first floor during to second layer transition (at the B point), because the β angle is very little, so the transverse component value of impelling wire rope laterally to arrange in order is also very little.Occurring behind the first lap that wire rope twining the second layer through regular meeting is not laterally to continue to twine the second layer, but directly twines the 3rd layer on the basis of second layer first lap, slides near the second layer first lap from the 3rd layer again immediately at once, promptly occurs " rope skipping phenomenon ".This " rope skipping phenomenon " can make wire rope heavy wear, ruptures even.
In addition, the existence owing to angle β makes when wire rope detours downwards, with a certain side friction of rope race sidewall generation in the large pulley group of mast top, the application life of also having reduced this pulley.
Summary of the invention
The purpose of this utility model designs at existing weak point in the above-mentioned prior art just, and a kind of wire rope of can effectively stopping is swung and its rope skipping phenomenon takes place when twining on master winch device reel rotary drilling rig significantly in the mast height scope.
The purpose of this utility model can realize by following technique measures:
Rotary drilling rig of the present utility model comprises the mast that combines with the rotary drilling rig main frame, is positioned at the large pulley group on mast top, is arranged on the master winch device reel of mast bottom, and the wire rope that is used to draw drilling rod; Wherein: be provided with by pulley support at the middle part of mast and be installed in the fixedly rope winding jib that the pulley on the pulley support is formed; Described haulage cable one end jointed rod, the other end is walked around mast top large pulley group, yet is passed down through the fixedly pulley and the master winch device reel Joint of rope winding jib.
Described in the utility model fixedly the pulley of rope winding jib be bearing on the bearing pin by rolling bearing, the two ends of bearing pin are fixedly mounted on the pulley support biside plate by limit stops; Interfere phenomenon when rotating and between the side plate, be provided with spacer at pulley and pulley support side sheet room for anti-limited slip wheel; Escape in pulley groove for preventing haulage cable, the utility model is provided with retaining rope pipe between the pulley support biside plate that is positioned at above the pulley, retaining rope pipe combines with the pulley support biside plate by the bearing pin that passes through its tube chamber, and therefore shelves rope pipe can rotate on bearing pin.
Why adopt the base plate of welding band screw on mast in advance in the utility model, by the mode that is threaded fixing rope winding jib is installed on this base plate the frame mode of (being described pulley support is installed on the screw thread base plate with the mast Joint by the mode that is threaded) afterwards again, its objective is simplified structure, the convenient installation.
The bolt hole that processes on the pulley support base plate of the present utility model is the long slot bore that is provided with along the mast width, can bearing be adjusted to suitable position by long slot bore during installation, pulley groove and mast top large pulley group middle pulley groove on the feasible fixedly rope winding jib are in same center line state basically.
Because the utility model has been set up fixedly rope winding jib at the mast middle part, and wire rope passed between rope winding jib pulley groove and retaining rope pipe, so just applied a pretightning force to wire rope, make that pulley and the wire rope between the rope winding jib pulley (line CD) in the large pulley group on mast top are a vertical line (see figure 2), this also just can stop the swing of wire rope effectively, flicker, drift, not only can play and prevent that wire rope and mast from rubbing, the problem of wearing and tearing mast oil cylinder piston rod, simultaneously also make the frictional resistance between wire rope and the mast top large pulley group rope race sidewall reduce greatly, can improve the application life of mast top large pulley group pulley and reduce maintenance capacity.
In addition, fixedly the setting of rope winding jib also makes and presents a bigger angle from the fixedly rope winding jib pulley (C point) at mast middle part and the wire rope between the master winch device reel, and promptly the angle γ between straight line AC and the BC has increased one times nearly than original angle β.When wire rope on the reel by first floor during to second layer transition, its lateral pull has increased nearly one times than being unkitted fixedly before the rope winding jib, and wire rope is laterally arranged on reel in order.Facts have proved, can effectively alleviate " rope skipping phenomenon " like this, improve the application life of wire rope greatly.
The utility model its major advantage compared to existing technology is as follows: not only can make wire rope can not rub, wear and tear with the mast oil cylinder piston rod; Simultaneously also increase the transverse component that wire rope twines on master winch device reel, can make wire rope on reel, arrange in order, prevented " rope skipping phenomenon ", improved the application life of wire rope greatly.
