Abstract
The utility model relates to a universal torque transmission chain. The universal torque transmission chain consists of at least two transmission chain nodes (1) which are mutually connected, wherein each transmission chain node (1) comprises a cylindrical chain node body (1a); a semi-circular chain node head (1b) is arranged at one end of the chain node body (1a); the last chain node head (1b) is matched with a chain node groove of the next chain node body; certain angle is formed between the axis of the chain node head and the projection of the axis of the chain node groove in the axial direction; and a protecting sleeve (2) which is in interference fit with each chain node body (1a) is arranged on the chain node body (1a). The universal torque transmission chain has the advantages that torque is transmitted by a chain structure, so that the universal torque transmission chain can deviate from the axis of the universal torque transmission chain for certain angle, and a drill stem can be quickly and conveniently assembled and disassembled.
Description
Technical field
The utility model relates to a kind of torque transmission, particularly a kind of universal torque transfer chain.
Background technique
All be to connect by retarder between the power motor of current driving force hair style well sinker and the drilling rod, namely by retarder the torque transfer that power motor produces arrived drilling rod.The power head drilling machine rate of penetration is fast, but the loading, unloading drilling rod is very inconvenient.If a kind of flexible torque transfer part that has is arranged, will bring great convenience to the loading, unloading drilling rod.
The model utility content
The purpose of this utility model is exactly in order to overcome the existing very inconvenient problem of power unit type well sinker loading, unloading drilling rod, a kind of universal torque transfer chain to be provided.
To achieve these goals, the utility model has adopted following technological scheme:
A kind of universal torque transfer chain; it is characterized in that: it is comprised of at least two interconnective transmission chain links; each transmission chain link comprises a columniform chain link body; chain link body one end is provided with the chain link groove of open circles cylindricality; the width of chain link channel opening is less than the diameter of chain link groove cylinder; the chain link body the other end is provided with a chain link neck; the chain link neck is provided with semi-cylindrical chain section header; chain link neck depth degree is less than the width of chain link channel opening; the axis of the axis of chain section header and chain link groove the chain link axon to projection at an angle; the chain section header of a upper chain link body forms with the chain link groove of next chain link body and cooperates, and a with it protecting jacket of interference fit is set on each chain link body.
The described chain link neck depth of such scheme degree is less than the width of chain link channel opening, and this structure can strengthen two transmission chain internode rotation angles that cooperatively interact; The axis of the axis of described chain section header and chain link groove the chain link axon to projection at an angle, this kind structure can make universal torque transfer chain go up rotation in any direction; The chain section header of a described upper chain link body and the chain link groove of next chain link body form and cooperate, and refer to that chain link groove inwall contacts fully and forms with the chain section header can cooperate in relative rotation.
In the such scheme
On the basis of technique scheme, following further scheme can be arranged:
Described chain link channel opening both sides are respectively equipped with an inclined-plane.
The length of described chain link body is greater than the length of protecting jacket.
Advantage of the present utility model: the utility model adopts the chain structure transfer of torque, and universal torque transfer chain can depart from its axis several angle, quickly and easily loading, unloading drilling rod.
Description of drawings:
Fig. 1 is structural drawing of the present utility model, and for surperficial linkage structure, middle two joint transmission chain links adopt the mode of broken section to represent;
Fig. 2 is the enlarged view of chain link body;
Fig. 3 is that the utility model is used for the schematic representation on the rig.
Embodiment:
Embodiment one:
Such as Fig. 1; shown in Figure 2; a kind of universal torque transfer chain that the utility model provides; it is comprised of at least two interconnective transmission chain links 1; each transmission chain link 1 comprises a columniform chain link body 1a; chain link body 1a one end is provided with the chain link groove 1d of open circles cylindricality; the width of chain link groove 1d opening is less than the diameter of chain link groove cylinder; the chain link body 1a the other end is provided with a chain link neck 1c; chain link neck 1c is provided with semi-cylindrical chain section header 1b; chain link neck 1c thickness is less than the width of chain link groove 1d opening; the axis of the axis of chain section header 1b and chain link groove 1d in the axial projection of chain link body 1a at an angle; the chain section header 1b of a upper chain link body 1a forms with the chain link groove 1d of next chain link body 1a and cooperates, and a with it protecting jacket 2 of interference fit is set on each chain link body 1a.
Described a kind of universal torque transfer chain is characterized in that: chain link groove 1d opening both sides are respectively equipped with an inclined-plane 1f.
Described a kind of universal torque transfer chain, it is characterized in that: the length of chain link body (1a) is greater than the length of protecting jacket (2).
Embodiment two:
As shown in Figure 3, a kind of universal torque transfer chain that the utility model provides adds one for the coupling 3 that connects power motor, is used for the drill rod connector 4 of jointed rod, forms the middle device that connects between power motor and drilling rod.Because universal torque transfer connects can crooked several angle, so loading, unloading drilling rod very easily.
Claims (3)
1. universal torque transfer chain; it is characterized in that: it is comprised of at least two interconnective transmission chain links (1); each transmission chain link (1) comprises a columniform chain link body (1a); chain link body (1a) end is provided with the chain link groove (1d) of open circles cylindricality; the width of chain link groove (1d) opening is less than the diameter of chain link groove cylinder; chain link body (1a) the other end is provided with a chain link neck (1c); chain link neck (1c) is provided with semi-cylindrical chain section header (1b); chain link neck (1c) thickness is less than the width of chain link groove (1d) opening; the axis of the axis of chain section header (1b) and chain link groove (1d) in the axial projection of chain link body (1a) at an angle; the chain section header (1b) of a upper chain link body (1a) forms with the chain link groove (1d) of next chain link body 1a and cooperates, and a with it protecting jacket of interference fit (2) is set on each chain link body (1a).
