The specific embodiment
Core of the present utility model provides a kind of drilling rod that is used for rotary drilling rig and carries leading-in device, and its elevator can return to vertical state voluntarily after skewed by external force, thereby has avoided elevator and drilling rod to wear and tear, and has improved the application life of elevator.Another core of the present utility model provides and a kind ofly comprises that above-mentioned drilling rod carries the rotary drilling rig of leading-in device.
In order to make those skilled in the art person understand the technical solution of the utility model better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1 and Fig. 2, Fig. 1 carries the sectional view of first kind of specific embodiment of leading-in device in main apparent direction for the drilling rod of rotary drilling rig that the utility model is provided for; Fig. 2 carries the sectional view of leading-in device in the side-looking direction for drilling rod shown in Figure 1.
Drilling rod provided by the utility model is carried leading-in device and is used for rotary drilling rig, and it is important transition member between wire rope and the drilling rod 2 that drilling rod is carried leading-in device, is the important composition parts of rotary drilling rig.This drilling rod is carried leading-in device and is comprised elevator 1 and hinging pin shaft 4, general drilling rod is carried leading-in device and is also comprised flat side 3, wherein, one end of elevator 1 and the wire rope of rotary drilling rig are hinged, the other end of elevator 1 is installed on the upper end of interior bar of the drilling rod 2 of rotary drilling rig, between elevator 1 and the drilling rod 2 elastic parts is installed, compression takes place with elevator 1 with respect to drilling rod 2 skew on axially or stretches in this elastic parts, thereby generation elastic force, the direction of the elastic force of this elastic parts and drilling rod 2 axially have a predetermined angular, in real work, because what cause the direction of the external force that elevator 1 skews and drilling rod 2 axially has certain angle, above-mentioned elastic parts is in the process that skews along with elevator 1, the direction of the elastic force of its generation obviously and the equal and opposite in direction of external force, direction is opposite, also promptly the elastic force that produces of this elastic parts and drilling rod 2 axially have a predetermined angular.
It is pointed out that the drilling rod of mentioning carries leading-in device and be meant general name between jointed rod 2 and the wire rope, that play the link of the parts of proposing the effect of drawing and these parts and wire rope and drilling rod 2 herein, be interpreted as comparatively generalized concept.
When elevator 1 is in the centering position, also be that the axis of the axis of elevator 1 and drilling rod 2 is when coinciding, elastic parts can be in free state, promptly this moment, elastic parts did not have elastic force, in when, under the effect of elevator 1 in external force the skew of a certain direction taking place when, the homonymy skew takes place with elevator 1 in elastic parts, elastic parts produces the elastic force opposite with external force direction, this elastic force may be because the elastic parts compression produces, it also may be generation because elastic parts stretches, apparently, the elastic force of elastic parts is to produce owing to stretching or because the offset direction of elevator 1 is depended in the compression generation, also is the above-mentioned direction that causes the external force of elevator 1 skew.When elevator 1 was in the centering position, elastic parts also was not limited to and is in absolute free state, and it also can be in the state of a small amount of stretching or small amount of compression.
The upper end of the interior bar of the drilling rod of mentioning in this manual 2 is meant, internal segment drilling rod is near the end face of elevator 1.
Elevator 1 can be directly installed on the upper end of interior bar of drilling rod 2, also can be installed on the upper end of interior bar of drilling rod 2 by flat side 3 indirectly.Flat side 3 is installed on the upper end of interior bar of described drilling rod 2, and elevator 1 offers the mounting groove towards flat side 3, and flat side 3 is installed in the mounting groove, and is fixed in the cell wall of mounting groove by bearing pin 4; Flat side 3 can be installed on the upper end of the interior bar of drilling rod 2 by the mode of welding, also can realize being connected of upper end of the interior bar of flat side 3 and drilling rod 2 by conventional other modes of using in this area, mode such as bolt connection for example, the surface of flat side's 3 close elevator 1 one sides is an arc-shaped surface, so that realize the rotation of elevator 1 with respect to flat side 3 surfaces, the radian size of flat side's 3 arc-shaped surface should be determined according to actual mode of occupation, not do qualification at this.Elevator 1 is installed on drilling rod 2 by flat side 3, has simplified the be connected technology of elevator 1 with drilling rod 2.
