Abstract
The invention relates to a grinding ring mounting structure of a geological prospecting drill. The grinding ring mounting structure comprises a grinding ring mounted at the end of a connector, the grinding ring is connected with the connector in a screwed manner, the side of the grinding ring is provided with a concave annular portion, a locking sleeve is mounted on the connector in a screwed manner and comprises a locking ring and an extrusion ring, the locking ring is connected with the connector in a screwed manner, the extrusion ring is mounted on the side of the locking ring, sleeves the connector and is placed in the concave annular portion, and the side of the extrusion ring is provided with an arc-shaped extrusion portion in contact connection with the inner wall of the concave annular portion. The grinding ring is connected with the connector in the screwed manner, but fully screwed connection is not formed, so that detachment is prevented from being affected by too tight connection. The grinding ring is locked by the locking sleeve and prevented from rotating in operation of a drill rod and affecting righting and reaming effects, and working reliability and efficiency of the drill rod are improved.
Description
Technical field
The present invention relates to geological prospecting apparatus field, relate in particular to rig grinding ring syndeton.
Background technology
Rig is requisite equipment in geological prospecting, and the drilling rod on rig is cylindricality strip structure, generally disposes grinding ring on drilling rod.The effect of grinding ring is that drilling rod is carried out righting and is beneficial to the reaming of drilling rod.Existing grinding ring is connected by connector and drilling rod conventionally, and take the mode being directly nested with to be connected between grinding ring and connector, in drilling rod rotation drilling operation, due to grinding ring periphery and drilling rod periphery and drill hole inner wall friction, the easily relative connector of grinding ring rotates, thereby impact is to the righting of drilling rod and reduction reaming effect.For addressing the above problem, occurred at present grinding ring and connector to adopt spiral connected mode, and adopted and screw dead mode and be connected, its shortcoming is to be not easy to grinding ring change.
Summary of the invention
The applicant is for the above-mentioned shortcoming of the connected mode existence of grinding ring and connector in existing drilling rod, study and improve, the grinding ring mounting structure that a kind of geological prospecting rig is provided, has improved the connective stability between grinding ring and connector, and is convenient to the replacing of grinding ring.
The technical solution adopted in the present invention is as follows:
A kind of grinding ring mounting structure of geological prospecting rig, comprise the grinding ring being installed on connector end, grinding ring is connected with connector spiral, the side of described grinding ring is with indent ring part, on described connector, go back screw and have lock sleeve, described lock sleeve comprises the retaining ring being connected with connector spiral and is installed on the extrusion ring of retaining ring side, described extrusion ring is placed on connector and is placed in described indent ring part, and the side of extrusion ring is with the arc press section touching with indent ring part inwall.
Beneficial effect of the present invention is as follows:
Between grinding ring of the present invention and adapter sleeve, spiral is connected, but does not form and revolve dead connection, thereby prevents from connecting tension impact dismounting; Adopt lock sleeve to lock grinding ring, prevent that grinding ring from rotating and affecting righting and reaming effect when drilling rod is worked, improve functional reliability and the efficiency of drilling rod.
Accompanying drawing explanation
Fig. 1 is main sectional view of the present invention.
Fig. 2 is the main sectional view of lock sleeve of the present invention.
In figure: 1, connector; 2, grinding ring; 21, indent ring part; 3, retaining ring; 4, extrusion ring; 41, arc press section.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As Fig. 1, shown in Fig. 2, the grinding ring mounting structure of the geological prospecting rig of the present embodiment, comprise the grinding ring 2 being installed on connector 1 end, grinding ring 2 is connected with connector 1 spiral, the side of grinding ring 2 is with indent ring part 21, on connector 1, go back screw and have lock sleeve, lock sleeve comprises the retaining ring 3 being connected with connector 1 spiral and is installed on the extrusion ring 4 of retaining ring 3 sides, extrusion ring 4 is made for quality of rubber materials, extrusion ring 4 is placed on connector 1 and is placed in indent ring part 21, the side of extrusion ring 4 is with the arc press section 41 touching with indent ring part 21 inwalls.
In the present invention, between grinding ring 2 and connector 1, spiral is connected, but do not form, does not revolve dead connection, prevents from connecting the dismounting that tension affects grinding ring 2; Adopt lock sleeve to grinding ring 2 lockings, in locking process, the inwall of the arc press section 41 of extrusion ring 4 and the indent ring part 21 of grinding ring 2 near, after 41 distortion of arc press section, be adjacent to it, prevent that grinding ring 2 from rotating and affecting righting and reaming effect when drilling rod is worked, improve functional reliability and the efficiency of drilling rod.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention is referring to claim, and without prejudice to spirit of the present invention in the situation that, the present invention can do any type of modification.
