Abstract
The utility model discloses a kind of tops to drive rotation casing pipe running device composite teeth slips, it is mainly made of contrate, perpendicular tooth, synchronous more conical surfaces and connecting hole, the contrate is perpendicular to the axis of slips engagement breadth, the perpendicular tooth is parallel with the axis of slips engagement breadth, the contrate and perpendicular tooth are respectively positioned on slips inner wall, and crown composition composite teeth slips engagement circle breadth.The utility model is by using the composite tooth form composite teeth of the perpendicular tooth of part contrate and part and the slips structure of more conical surface synchronous matchings, when ensureing composite teeth slips grip sleeve, larger axial load and circumferential load can be carried, when driving rotation casing pipe running device using top, the casing tubing string of heavy load can be carried and carry the large torque of revoling tube tubing string.
Description
Technical field
The utility model is related to the drilling equipment technical fields of oil-gas field development, specifically relate to a kind of top and drive under rotation
Casing bit composite teeth slips.
Background technology
It is a kind of based on top drive drilling apparatus that rotation casing pipe running device is driven on top, and the auxiliary for carrying out casing job is set
It is standby, it can realize the Fast Installation, casing rapid extraction and upper button connection, the tripping in of casing tubing string and Xun Huan tripping in of equipment, can improve
Setting of casing mode reduces setting of casing difficulty, saves the setting of casing time, has larger technical advantage.
There are mainly three types of types for the slips tooth of current various drilling equipments and underground anchor tool.One kind be drill pipe slip,
Casing slip, the slips tooth of various underground anchor tools are mainly contrate, can bear larger axial load, but the week that can be born
It is smaller to torque.Another kind is the predominantly perpendicular tooth of pincers tooth of casing tong, drilling fluid gas tong, thread screw on and-off machine etc., can be born larger
Circumferential torque, but the axial load that can be born is smaller.Also one kind is part drill pipe slip, casing slip, casing tong, drilling fluid
The tooth form of gas tong, thread screw on and-off machine etc. is non-contrate and the taper pointed tooth of perpendicular tooth, can carry axial load and circumferential load, but carry
Axial load and circumferential load be not very big.Rotation casing pipe running device is driven in grip sleeve in top, and slips tooth connects with casing
Contact portion position should carry the weight of casing tubing string and the large torque of casing tubing string rotation and also carry and be carried when meeting down hole problem
The additional load of casing tubing string and the additional torque of revoling tube tubing string are put, total axial load and circumferential load are all very big.
Existing common slips tooth form cannot meet larger axial load and the week of rotation casing pipe running device while carrying
Requirement to load.A kind of new slips tooth-shape structure is needed, carrying is axial when improving rotation casing pipe running device grip sleeve
The ability of load and circumferential load just can guarantee the use that rotation casing pipe running device at the scene can be safe and reliable, so as to fully send out
It waves top and drives the effect that rotation casing pipe running device improves tube efficiency of trapping.
Utility model content
The utility model is intended to the defects of existing for the above-mentioned prior art and deficiency, provides a kind of top drive rotation and traps
Pipe device composite teeth slips, composite tooth form composite teeth and the more conical surface of the utility model by using the perpendicular tooth of part contrate and part
The slips structure of synchronous matching when ensureing composite teeth slips grip sleeve, can carry larger axial load and circumferential load, adopt
When driving rotation casing pipe running device with top, the casing tubing string of heavy load can be carried and carry the large torque of revoling tube tubing string.
The utility model is realized by using following technical proposals：
Drive rotation casing pipe running device composite teeth slips in a kind of top, it is characterised in that：Mainly by contrate, perpendicular tooth, synchronous more cones
Face and connecting hole composition, the contrate engage the axis of breadth perpendicular to slips, and the perpendicular tooth engages the axis of breadth with slips
Parallel, the contrate and perpendicular tooth are respectively positioned on slips inner wall, and crown composition composite teeth slips engagement circle breadth.Grip sleeve can be held
Carry the effect of larger axial and circumferential load.
The more conical surfaces of synchronization are located at slips outer wall, with crown composition engage circle breadth it is concentric, and with synchronous more conical surfaces
Cone coordinates.
The connecting hole is located at the rear end of composite teeth slips, is attached by bolt and composite teeth slips bindiny mechanism.
Compared with prior art, what the utility model was reached has the beneficial effect that：
1st, in the utility model, slips tooth tooth form is by two kinds of tooth forms of contrate and perpendicular tooth, positioned at slips inner wall, grip sleeve
When, very big casing tubing string weight can be carried and carry very big revoling tube tubing string torque.
2nd, in the utility model, slips outer wall is coordinated using synchronous more cone structures, and with the cone of synchronous more conical surfaces, can
Increase composite teeth slips flank of tooth length, contact area when increasing grip sleeve can carry the heavy load of axial and circumferential, reduce
Casing catcher mark, moreover it is possible to realize that larger cooperation taper and shorter axial stroke realize the clamping and release of casing.
3rd, in the utility model, it is connected with bindiny mechanism by connecting hole, is covered convenient for control slips grip sleeve and release
Pipe.
Description of the drawings
Below in conjunction with specification drawings and specific embodiments, the utility model is described in further detail,
In：
Fig. 1 is the structure diagram that rotation casing pipe running device composite teeth slips is driven on the utility model top.
Fig. 2 is A-A views in Fig. 1.
Fig. 3 is B-B views in Fig. 1.
Fig. 4 is I portions enlarged view in Fig. 1.
Wherein, 1- erects tooth, 2- contrates, 3- connecting holes, the synchronous more conical surfaces of 4-.
Specific embodiment
It is the most preferred embodiment of the utility model below, the utility model is carried out specifically with reference to Figure of description
It is bright.
More conical surfaces can be 2 conical surfaces, 3 conical surfaces or more the conical surface, in structure diagram by taking 3 conical surfaces as an example.
The utility model mainly includes the compositions such as perpendicular tooth 1, contrate 2, connecting hole 3, synchronous more conical surfaces 4.The contrate 2 is vertical
In the axis of slips engagement breadth, the perpendicular tooth 1 is parallel with the axis of slips engagement breadth, and the contrate 2 and perpendicular tooth 1 are located at card
Watt inner wall, and form composite teeth slips engagement circle breadth.
The more conical surfaces 4 of synchronization are located at the outer wall of slips, with the crown of perpendicular tooth 1, contrate 2 form to engage circle breadth same
The heart.
The connecting hole is located at the rear end of composite teeth slips, can be bolted with bindiny mechanism.
The utility model is mounted on top and driven in the cone of rotation casing pipe running device clamping device, together by field conduct mode
More cone match installations, both sides insertion /V are walked, and passes through connecting hole and is connected with control mechanism.By control mechanism under rotation
The utility model is promoted in casing bit clamping device, the utility model is received along synchronous more conical surface downlinks and clamps casing, so
After can carry out rotation casing job.Under casing in place after, relief sleeve weight and torque load, by control mechanism to rotation
The utility model is pulled outside casing pipe running device clamping device, the utility model opens relief sleeve, rotation along outside synchronous more conical surface uplinks
Turn casing job to terminate.
