Abstract
The invention discloses a connector for prolonging the service life of a diamond composite drill bit. The connector is characterized by structurally being a long casing pipe, an outer thread (1) and an anti-torsion step (2) are arranged at one end of the long casing pipe, an outer thread (3) and an anti-torsion step (4) are arranged at the other end of the long casing pipe, and the long casing pipe is connected with the composite drill bit. The connector is connected with a drilling tool and the drill bit, so that when the drill bit is taken down or a rock core is taken down, the drill bit or the rock core is taken down only by knocking the connector. In this way, artificial damage to the drill bit is avoided, the service life of the drill bit is prolonged, and finally exploration cost is lowered. The connector is reasonable in structure, simple, practicable, good in anti-torsion effect low in manufacturing cost and good in effect, and is of great significance to control over the exploration cost.
Description
technical field
The invention belongs to geological core drilling technical field, specifically a kind of diamond compact bit connector in application life that improves.
background technology
In geological core drilling process, diamond compact bit is directly connected with drilling tool conventionally, and coring or while removing drill bit will knock drilling tool or drill bit with iron hammer, and compact bit is different from common diamond, knocks rear easy damage, distortion.
summary of the invention
For fear of compact bit because knocking distortion, damaging, the invention provides a kind of diamond compact bit connector in application life that improves, this connector is by connecting drilling tool and drill bit, when removing drill bit or coring, only need knock this connector, just can reach and remove drill bit or coring object.
The technical solution adopted for the present invention to solve the technical problems is: the structure that improves the connector in diamond compact bit application life is a long sleeve pipe, and one end of long sleeve pipe is external screw thread and antitorque step, is connected with basket; The other end is external screw thread and antitorque step, is connected with composite drill bit.
The invention has the beneficial effects as follows compared with the prior art:
?
Improve the connector in diamond compact bit application life by connecting drilling tool and drill bit, when removing drill bit or coring, only need knock this connector, just can remove drill bit or coring.Thereby avoided the artificial damage of drill bit, and then extended the application life of drill bit, finally reduced exploration cost.This connector construction is reasonable, simple and practical, antitorque effective.Connector cost is low, effect is large, significant to controlling exploration cost.Can penetration and promotion in geological core drilling, have a extensive future, remarkable in economical benefits.
accompanying drawing explanation
Fig. 1 is connector construction schematic diagram of the present invention.
In figure, 1,3-external screw thread, 2, the antitorque step of 4-, the long sleeve pipe of 5-.
the specific embodiment
As shown in Figure 1, connector of the present invention is that the long sleeve pipe of a direct linkage type 5 ，Qi one end are external screw thread 1 and antitorque step 2, and this end is connected with basket; The other end is external screw thread 3 and antitorque step 4, and this end is connected with composite drill bit, and the long cover of connector body pipe range is 30～40cm.
During use:
(1) conventional drilling tool, compact bit type, size in probing are concluded to summary, for drilling tool, by bore, divide Ф 146mm, Ф 127 mm, Ф 108 mm, Ф 89 mm; For drill bit, by bore, divide Ф 150 mm, Ф 130 mm, Ф 110 mm, Ф 91 mm.
(2) determine connected mode: connector adopts and is threaded with drill bit, drilling tool, and screw thread appearance takes to show that heat treatment, chromium plating and screw thread show the methods such as Tungsten Carbide Surfacing steel wearing layer, can significantly extend its application life.
(3) determine connector two ends screw thread type and size: connector one end connects drilling tool, one end connects drill bit, therefore connector is connected one end with drilling tool, is " pin thread ", and being connected one end with drill bit is " pin thread ", and size and drilling tool, drill bit are supporting.
(4) by step processing connectors such as car, pincers.
Claims (1)
1. improve the diamond compact bit connector in application life, the structure that it is characterized in that connector is a long sleeve pipe, and one end of long sleeve pipe is external screw thread (1) and antitorque step (2), is connected with basket; The other end is external screw thread (3) and antitorque step (4), is connected with composite drill bit.
