Abstract
The utility model relates to a connection structure of an abrasion resistant ring and a joint in a drilling rig. The connection structure comprises the abrasion resistant ring and the joint, and is characterized in that the abrasion resistant ring and the joint are screwed with each other; a plurality of grooves are uniformly distributed in the outer wall of the abrasion resistant ring. The connection structure adopts the screwed connection manner to achieve fixation between the abrasion resistant ring and the joint, so that the correction effect and hole enlarging effect of the drill rod by the abrasion resistant ring are greatly improved; the grooves in the outer wall of the abrasion resistant ring can facilitate the friction with other textures, so that the hole enlarging effect is further improved.
Description
Technical field
The utility model relates to geological prospecting apparatus field, relates in particular to the servicing unit of drilling rod on rig.
Background technology
Rig is requisite equipment in geological prospecting, and the drilling rod on rig is cylindricality strip structure, generally disposes wear ring on drilling rod, and its effect is on the one hand drilling rod to be carried out to righting, is to be conducive to reaming on the other hand.Existing wear ring is connected with drilling rod by joint, between wear ring and joint, take the mode being directly nested with to be connected, in drilling rod rotary course, due to wear ring and by the friction between boring, make to relatively rotate between wear ring and joint, thereby both affected the righting to drilling rod, reduced again reaming effect; In drilling rod boring procedure, the friction between existing wear ring and geology is less, causes reaming effect undesirable.
Utility model content
The applicant, for the above-mentioned shortcoming of existing wear ring and joint connection manner, studies and improves, and wear ring in a kind of rig and the syndeton of joint are provided, and has improved the connective stability between wear ring and joint, has improved reaming effect.
The technical scheme that the utility model adopts is as follows:
Wear ring in rig and a syndeton for joint, comprise wear ring and joint, it is characterized in that: between described wear ring and joint, adopt and be threaded; On the outer wall of described wear ring, be evenly equipped with a plurality of grooves.
The beneficial effects of the utility model are as follows:
The mode being threaded that adopts the utility model realizes fixing between wear ring and joint, has greatly improved wear ring to the righting effect of drilling rod and reaming effect; Groove on wear ring outer wall is conducive to the friction between itself and geology, has further improved reaming effect.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
See Fig. 1, the utility model comprises wear ring 2 and joint 1, and wear ring 2 has internal thread 21, and joint 1 has the external screw thread 11 matching with internal thread 21, between wear ring 2 and joint 1, by spiral between internal thread 21 and external screw thread 11, is connected; On the outer wall of wear ring 2, be evenly equipped with a plurality of grooves 22, groove 22 is conducive to the friction between wear ring 2 and geology, thereby improves reaming effect.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, and without prejudice to spirit of the present utility model in the situation that, the utility model can be done any type of modification.
Claims (1)
1. a syndeton for the wear ring in rig and joint, comprises wear ring and joint, it is characterized in that: between described wear ring and joint, adopt and be threaded; On the outer wall of described wear ring, be evenly equipped with a plurality of grooves.
