Abstract

A mast link frame system of a rotary drilling rig comprising a mast, a tripod, a connected hold plate, a rotary table, a hydraulic bar I, a hydraulic bar II, and a hydraulic bar III. The said rotary table is hinged with one end of the hydraulic pipe I, the other end of hydraulic bar I, mast and connected hold plate are all hinged with tripod, the hinged joints are located at three corners of tripod; one end of the hydraulic bar II is hinged with tripod, hinged joints are at one side of the tripod, respectively, the other end of hydraulic bar II is hinged with mast near the hinged joint of tripod and connected hold plate; one end of hydraulic bar III is hinged with the rotary table and the other end of the hydraulic bar III is hinged with the connected hold plate, the connected hold plate is hinged with rotary table, mast is connected with power head through platform, drilling rod traversing power head is connected with drilling tool at the forepart of power head. The present invention has a simple and reasonable structure and also great stability, can satisfy needs at different work conditions and driving conditions as well as realize exact location of the drilling tool, and also has high perpendicular precision of mast and wide application fields.

Description

A kind of rotary drilling rig jib lubbing mechanism
Technical field
The present invention relates to a kind of jib lubbing mechanism, especially relate to a kind of rotary drilling rig jib lubbing mechanism.
Technical background
Rotary drilling rig is the modern common drill-pouring construction machinery in the construction field of building, and jib lubbing mechanism is to connect rotary drilling rig turntable and one of vitals that bores mast, bores rising and falling and boring the stability of mast when unit head work and control by jib lubbing mechanism and finish of mast.At present, the rotary drilling rig jib lubbing mechanism mainly is divided into two kinds of three fulcrum types and many fulcrum types; Wherein, three fulcrum types stability is better, but adjusts with loading and unloading inconvenient; Many fulcrum types are easy to adjust, but because hinge is more, processing is all inconvenient with installation.
The tripod that Chinese patent CN200920045366.5 discloses a kind of rotary drilling rig connects jib lubbing mechanism, be on traditional triangle frame basis, to set up jointed shaft, it is linked to each other with connecting rod by amplitude oil cylinder, pin joint on the tripod is increased to five, have only two connecting rods and turntable to be hinged in the whole jib lubbing mechanism, this structure has reduced the cost of production of complete machine to a certain extent, but, connect the existence of the connecting rod of tripod and turntable, make the needed power of luffing raise, in addition, too many because of the hinge edge point on the tripod, the requirement of strength of tripod material is also further improved.
Chinese patent CN200820053062.9 discloses a kind of luffing jib mechanism of rotary drilling rig, introduced a boom structure in this mechanism, only realized the lifting of rotary drilling rig equipment by a hydraulic cylinder, structure is relatively simple, but the existence of swing arm makes the device resistance to overturning reduce, this mechanism only is applicable to middle-size and small-size rig, and the scope of application is little.
Summary of the invention
In order to overcome the above-mentioned defective that prior art exists, the invention provides a kind of good stability, rotary drilling rig jib lubbing mechanism applied widely.
Technical scheme of the present invention is: it comprises mast, tripod, connect fagging, turntable, also comprise the hydraulic stem I, the hydraulic stem II, the hydraulic stem III, described turntable and hydraulic stem I one end are hinged, the hydraulic stem I other end, mast is with to be connected fagging all hinged with tripod, pin joint lays respectively on three angles of tripod, hydraulic stem II one end and tripod are hinged, pin joint is on the limit of tripod, the hydraulic stem II other end and mast are hinged, hydraulic stem III one end and turntable are hinged, the hydraulic stem III other end is with to be connected fagging hinged, it is hinged to connect fagging and turntable, mast links to each other with unit head by platform, and drilling rod passes unit head and links to each other with the drilling tool of being located at the unit head front end.
The preferred equilateral triangle of described tripod shape is beneficial to make tripod to have even stand under load characteristic.
Described connection fagging shape is preferably triangle, connects fagging and tripod, hydraulic stem III, three hinged pin joints of turntable are in respectively on three angles that are connected fagging.
Operating principle of the present invention is: tripod, hydraulic stem I, connection fagging and turntable are hinged and have constituted a parallel-crank mechanism, under the effect of hydraulic stem III, this parallel-crank mechanism can deform, make tripod produce change in displacement, thereby change the position of the mast link to each other with tripod, the stretching motion of realization mast, the effect by hydraulic stem again, can effectively regulate the angle of inclination of mast, realize the luffing of this mechanism.
The present invention is simple in structure, and stability is strong, can satisfy the needs of different operating state and travel position, realizes the accurate location of drilling tool, and the vertical precision height of mast is applied widely.
Description of drawings
Fig. 1 is an embodiment of the invention structural representation.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to Fig. 1, present embodiment comprises mast 4, tripod 5, hydraulic stem I 6, hydraulic stem II 7, hydraulic stem III 8, connect fagging 9, turntable 10, described tripod 5 is shaped as equilateral triangle, has even stand under load characteristic, described turntable 10 is hinged with hydraulic stem I 6 one ends, hydraulic stem I 6 other ends, mast 4 is with to be connected fagging 9 all hinged with tripod 5, pin joint lays respectively on three angles of tripod 5, hydraulic stem II 7 one ends and tripod 5 are hinged, pin joint is on the limit of tripod 5, near being positioned at tripod 5 and being connected the pin joint that fagging 9 links to each other, hydraulic stem II 7 other ends and mast 4 are hinged, hydraulic stem III 8 one ends and turntable 10 are hinged, hydraulic stem III 8 other ends are with to be connected fagging 9 hinged, it is hinged with turntable 10 to connect fagging 9, and mast 4 links to each other with unit head 2 by platform 11, and drilling rod 3 passes unit head 2 and links to each other with the drilling tool 1 of being located at unit head 2 front ends; Described connection fagging 9 is shaped as triangle, connects fagging 9 and tripod 5, hydraulic stem III 8, turntable 10 three hinged pin joints are in respectively on three angles that are connected fagging 9.
