Abstract
The invention relates to a clamp spring for holding a rock core. The clamp spring comprises a clamp spring body of a cylindrical structure, the clamp spring body is formed by winding a thin sheet, and a gap groove is formed in one side of the clamp spring body. A plurality of inserting holes are formed in the side wall of the clamp spring body in a spiral mode. The inserting holes are tilted relative to a center shaft of the clamp spring body to be formed towards the lower end of the center shaft of the clamp spring body, and holding screws are inserted in the inserting holes respectively. Screw columns and screw heads of the holding screws are arranged to be relatively oblique, and the ends of the screw columns are symmetrically provided with holding grooves. According to the clamp spring for holding the rock core, the holding screws and the clamp spring body are in detachable connection, and independent replacing of the holding screws is facilitated. Compared with overall replacing of a traditional clamp spring, the cost is greatly lowered. Compared with a groove in the inner wall of the clamp spring, the friction force to the rock core is large, and the holding force and the efficiency are improved.
Description
Technical field
The present invention relates to geological prospecting apparatus field, relate in particular to rig.
Background technology
Rig is requisite equipment in geological prospecting, and rig, when drilling through rock core, utilizes jump ring that rock core is taken out from underground armful.Existing jump ring is for the loop configuration of sealing and with certain tapering, and the inwall of jump ring is provided with many grooves; During work, jump ring is embraced rock core to get by the frictional force between its inwall and rock core, and the shortcoming of this jump ring is not enough to armful power taking of comparatively soft rock core, and rock core easily comes off, and need to repeatedly embrace and get ability success, causes inefficiency; The groove serious wear of jump ring its inwall after use a period of time, is not easy to it to repair, and must change whole jump ring, and its replacement cost is higher.
Summary of the invention
The applicant embraces for existing rock core the above-mentioned shortcoming that the jump ring of taking exists, and studies and improves, provide a kind of operating efficiency high, embrace power taking foot, the rock core being convenient to repair embraces the jump ring of taking.
The technical solution adopted in the present invention is as follows:
Rock core is embraced a jump ring of taking, and comprises the jump ring body of tubular construction, and described jump ring body is by coil sheet around forming, and one side is with clearance groove; The sidewall spiral of described jump ring body is with a plurality of jacks, the inclined of the relative jump ring body of described jack arranges to its lower end, in jack, be plugged with respectively to embrace and get screw, described armful of screw pole and the setting of head of screw relative tilt of getting screw, the end symmetry of screw pole is got groove with embracing.
Further improvement as technique scheme:
Angle of slope between the angle head of screw relative to screw pole between the central axis of the relative jump ring body of central axis of described jack equates.
Beneficial effect of the present invention is as follows:
The present invention adopt to embrace and to get screw and be connected with the detachable of jump ring body, conveniently to armful getting screw, changes separately, compares traditional jump ring integral replacing, and its cost reduces greatly; Embrace and get the groove that screw is compared jump ring inwall, its frictional force to rock core is large, has improved armful power taking and efficiency.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figures 1 to 4, the rock core of the present embodiment is embraced the jump ring of taking, and comprises the jump ring body 1 of tubular construction, jump ring body 1 by coil sheet around forming, one side is with clearance groove 12, and clearance groove 12 is the elastic deformation when embracing coring for jump ring body 1, improves the power taking of embracing to rock core; The sidewall spiral of jump ring body 1 is with a plurality of jacks 11, and the inclined of jack 11 relative jump ring bodies 1 arranges to its lower end, is plugged with respectively to embrace to get screw 2 in jack 11, embraces to get that screw 2 can be threaded connection with 1 of jump ring body or spot welding is connected.
As shown in Figure 5, embrace the screw pole 21 and head of screw 22 relative tilt settings of getting screw 2, the end symmetry of screw pole 21 is got groove 23 with embracing, and embraces and gets the frictional force between groove 23 and rock core.
The angle of slope that angle head of screw relative to screw pole 21 between the central axis of the relative jump ring body 1 of central axis of jack 11 is 22 equates, is typically provided between 30 ° to 45 °.
Get screw 2 and 1 of jump ring body is easy for installation and removal for of the present invention armful, be convenient to get screw and change separately embracing, thereby reduce replacement cost.
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.
