Description
Technical field
The utility model relates to engineering geological drilling field, especially a kind of novel lock ring elevator.
Background technology
In Engineering Geologic Drilling Practice, drilling rod and drilling tool are put into ground (or in hole) by (or ground) in hole after mentioning, and it is all manually operated by workman on ground installing and unloading.The labour intensity that has so not only strengthened workman, has increased idle work, has also expended a large amount of time, has a strong impact on drilling depth.At present, rig is carried leading-in device and is generally used snap ring to fix drilling rod, but due in the cargo handling process of drilling rod, carrying leading-in device rotates with drilling rod, thereby cause snap ring stuck, if will take off drilling rod from elevator, must use hammer firmly to beat snap ring or drilling rod, so just can be removed, and carry out drilling rod installation or removal below.And widely used elevator, generally its inner chamber bore is all large than drill pipe diameter, causes drilling tool slippage accident once in a while, gently false alarm, heavy fatal crass.
Utility model content
In order to address the above problem, the utility model proposes a kind of novel lock ring elevator, the fixing snap ring on traditional elevator is replaced to a kind of adjustable type lock ring being easy to open and close by it, and increase the friction factor of elevator, can either realize being closely fixedly connected with of elevator and drilling rod and drilling tool, for convenience detach again, there is good practicality.
The utility model solves the technical scheme that its technical problem adopts: a kind of novel lock ring elevator, comprise elevator main body, and be welded in the drop handle on elevator main body top; Described elevator lower body part is provided with drilling rod adapter sleeve, and the sidewall of drilling rod adapter sleeve is provided with bar mouth; On described drilling rod adapter sleeve, corresponding bar mouth is provided with drilling rod fastening devices, and described drilling rod fastening devices comprises one section of arc bolt, and one end of bolt and drilling rod adapter sleeve are hinged, and the other end is provided with lockhole, and on drilling rod adapter sleeve, corresponding lockhole is welded with snap close; The medial surface of described drilling rod adapter sleeve and bolt is equipped with anti-skid structure; On described drilling rod adapter sleeve, circumferential uniform radial direction through hole, is equipped with clamping bolt in described through hole, and the inner end of described clamping bolt is spherical bolt head, and the outer end of clamping bolt is provided with pull bar; In described through hole, be provided with Compress Spring, described Compress Spring is enclosed within clamping bolt outside, and one end of Compress Spring is fixedly connected with clamping bolt, and the other end is connected with drilling rod adapter sleeve.
Described through hole is 3.
Described clamping bolt is 3.
The beneficial effects of the utility model are: a kind of novel lock ring elevator, the fixing snap ring on traditional elevator is replaced to a kind of adjustable type lock ring being easy to open and close by it, and increase the friction factor of elevator, can either realize being closely fixedly connected with of elevator and drilling rod and drilling tool, for convenience detach again, there is good practicality.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing 1 is a kind of structural representation of novel lock ring elevator.
In figure, 1. drop handle, 2. elevator main body, 2-1. drilling rod adapter sleeve, 2-2. bar mouth, 2-3. bolt, 2-4. snap close, 2-5. through hole, 2-6. clamping bolt, 2-7. Compress Spring, 2-8. pull bar.
Detailed description of the invention
In the accompanying drawings, a kind of novel lock ring elevator, comprises elevator main body 2, is welded in the drop handle 1 on elevator main body top; Described elevator main body 2 bottoms are provided with drilling rod adapter sleeve 2-1, and the sidewall of drilling rod adapter sleeve 2-1 is provided with bar mouth 2-2; The upper corresponding bar mouth 2-2 of described drilling rod adapter sleeve 2-1 is provided with drilling rod fastening devices, described drilling rod fastening devices comprises one section of arc bolt 2-3, one end of bolt 2-3 and drilling rod adapter sleeve 2-1 are hinged, and the other end is provided with lockhole, and the upper corresponding lockhole of drilling rod adapter sleeve 2-1 is welded with snap close 2-4; The medial surface of described drilling rod adapter sleeve 2-1 and bolt 2-3 is equipped with anti-skid structure; The upper circumferential uniform radial direction through hole 2-5 of described drilling rod adapter sleeve 2-1, is equipped with clamping bolt 2-6 in described through hole 2-5, and the inner end of described clamping bolt 2-6 is spherical bolt head, and the outer end of clamping bolt 2-6 is provided with pull bar 2-8; In described through hole 2-5, be provided with Compress Spring 2-7, described Compress Spring 2-7 is enclosed within clamping bolt 2-6 outside, and one end of Compress Spring 2-7 is fixedly connected with clamping bolt 2-6, and the other end is connected with drilling rod adapter sleeve 2-1.
Described through hole 2-5 is 3.
Described clamping bolt 2-6 is 3.
When use, first bolt 2-3 is opened, drilling rod is inserted to drilling rod adapter sleeve 2-1, clamping bolt 2-6 clamps drilling rod in the effect of Compress Spring 2-7, then, by bolt 2-3 and snap close 2-4 closure, drilling rod is fixed; Because there is anti-slip veins the inside of drilling rod adapter sleeve 2-1 and bolt 2-3, drilling rod is difficult for sliding or rotating, thereby avoids drilling rod and drilling tool landing and accidents caused.In the time that needs carry out drilling rod dismounting, first bolt 2-3 is opened, pinch pull bar 2-8 clamping bolt 2-6 is pulled out, make it loosen the clamping to drilling rod, can conveniently drilling rod be taken off.
