Abstract
The utility model relates to a well mouth power hanging device for a drilling rig, and relates to a small mechanical tool of a drill well mouth, and particularly relates to well mouth power hanging device for a drill rig, which comprises a quadrel base, two chutes are symmetrically arranged in the quadrel base, each chute is provided with a wide upper part and a narrow lower part, the lower end of the chute is fixedly provided with a limit step which is protruded out of the chute, the two chutes are internally and respectively provided with a loading slider, the loading slider is provided with a long round through hole, a bearing shaft penetrates through the through hole, cylinders are respectively arranged at two sides of the lower end of each loading slider in the quadrel base, two ends of the bearing shaft are respectively and fixedly connected with a piston rod of the cylinder, and the quadrel base is internally provided with an air passage communicated with the cylinder. In the utility model, the limit step at the bottom of the loading slider loads the weight of a drill tool, at the time, the loading slider and the drill tool body are not in contact, as the quadrel base is different from the conventional slip that loads the weight of the drill tool by the friction force of a dental plate and the drill tool, the drill rig can not be damaged, the working efficiency is high, and the safety is high.
Description
Technical field
The utility model relates to a kind of drilling well well head power choring instrument, particularly a kind of drilling tool well head power linkage.
Background technology
The drilling tool that existing oil drilling adopts two ends up and down all is a joint, during round trip, mostly be to adopt two elevator operations and to hang a card operating type, it is big that two elevator operating types exist labor strength, inefficiency, cause problems such as Important Project that single-suspender rig down causes and personal injury easily, present a plurality of oil fields are disabled; One hangs a card operating type, if adopt manual slip, it is big to exist labor strength equally, ineffective problem; If adopt power slip, though it is big to have solved labor strength, ineffective problem, but the available dynamic slips all is a frictional force of utilizing slip dog and drilling tool to produce comes the mode of the tight drill string of contract to carry drill string weight, thereby the crown of slip dog can damage drilling tool, is having a strong impact on the application life of drilling tool.
Summary of the invention
The purpose of this utility model is: provides a kind of and can not damage drilling tool, and high efficiency, safe drilling tool well head power linkage.
The purpose of this utility model is achieved in that a kind of drilling tool well head power linkage, comprise a quadrel seat, be symmetrical arranged two skewed slots wide at the top and narrow at the bottom in the described quadrel seat, described each skewed slot lower end fixedly installs the limited step that protrudes skewed slot respectively, a carrying slide block is set respectively in described two skewed slots, on the described carrying slide block Long Circle through hole is set, place bolster in the described through hole, the both sides, lower end of each carrying slide block are provided with a cylinder respectively in the described quadrel seat, the two ends of described bolster are the piston rod of a fixedly connected cylinder respectively, and the gas channels that is communicated with cylinder is set in the described quadrel seat.
Operating principle of the present utility model: the utility model need cooperate special drilling tool to use, only need to be provided with in one meter of below the common drilling tool female joint length boss greater than drilling tool body diameter, instantly bore when needing to hang drilling tool, give cylinder top air feed by gas channels, piston rod is by back shaft pulling carrying slide block down, behind the limited step of carrying slide block down skewed slot bottom to the quadrel seat, the diameter of a circle that the two carrying slide blocks that are symmetrically distributed form is a minimum value, but diameter greater than the drilling tool body, continue to transfer drilling tool, the drilling tool boss will be located on the carrying slide block, the weight that axially hang drilling tool by the carrying slide block this moment; When carrying drilling tool on pulling out of hole, give cylinder bottom air feed by gas channels, it is up that piston rod promotes the carrying slide block by bolster, when cylinder runs to top dead-centre, the diameter of a circle that the two carrying slide blocks that are symmetrically distributed form is a maximum value, gets out of the way the drilling tool passage, so that propose drilling tool.
The utility model is by carrying slider bottom limited step carrying drilling tool weight, this moment carries slide block and the drilling tool body is contactless, be different from conventional KAWAl and carry drilling tool weight by the dental lamina and the frictional force of drilling tool, thereby can be to the injury of drilling tool, and high efficiency, safe.
As further improvement of the utility model, on the described bolster axle sleeve is set.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is that the AA of Fig. 1 is to structural representation.
Fig. 3 is the vertical view of Fig. 1.
Wherein, 1-quadrel seat, 2-carrying slide block, the female joint of 3-drilling tool, 4-drilling tool body, 5-boss, 6-cylinder, 7-bolster, 8-gas channels, 9-limited step, 10-through hole, 11-axle sleeve.
The specific embodiment
As Fig. 1,2, shown in 3, a kind of drilling tool well head power linkage, comprise a quadrel seat 1, be symmetrical arranged two skewed slots wide at the top and narrow at the bottom in the quadrel seat 1, each skewed slot lower end fixedly installs the limited step 9 that protrudes skewed slot respectively, a carrying slide block 2 is set respectively in two skewed slots, on the carrying slide block 2 Long Circle through hole 10 is set, place bolster 7 in the through hole 10, the both sides, lower end of each carrying slide block 2 are provided with a cylinder 6 respectively in the quadrel seat 1, the two ends of bolster 7 are the piston rod of a fixedly connected cylinder 6 respectively, and the gas channels 8 that is communicated with cylinder 6 is set in the quadrel seat 1, and axle sleeve 11 is set on the bolster 7.
Claims (2)
1. drilling tool well head power linkage, it is characterized in that: comprise a quadrel seat, be symmetrical arranged two skewed slots wide at the top and narrow at the bottom in the described quadrel seat, described each skewed slot lower end fixedly installs the limited step that protrudes skewed slot respectively, a carrying slide block is set respectively in described two skewed slots, on the described carrying slide block Long Circle through hole is set, place bolster in the described through hole, the both sides, lower end of each carrying slide block are provided with a cylinder respectively in the described quadrel seat, the two ends of described bolster are the piston rod of a fixedly connected cylinder respectively, and the gas channels that is communicated with cylinder is set in the described quadrel seat.
