Abstract
The utility model relates to the realization stepless variable-angle type drill pipe clamp concentric with drilling rod in a kind of drilling operation process.It comprises base, repacking jack, rotary body, pedal and slips body.Pedal and rotary body are hinged by pedal bearing pin, the slips body of mounting strap slip skeleton in rotary body groove, and foot pedals realizes slips and opens.The ear of the ear seat of base, rotary body and repacking jack is hinged and is formed slider-crank mechanism action mode by bearing pin ear, the flexible stepless change that can realize clamping angle of repacking jack.The utility model is simple and compact for structure, and processing ease is easy to maintenance, supports different top angle drilling operation, little to the damage of drilling rod.
Description
Technical field
The utility model relates to a kind of drilling operation clamper, especially a kind of drill rod grip device of realizing stepless angle in large drift angle drilling operation process.
Background technology
In drilling operation process, for the larger boring of drift angle, drilling rod in boring also in large drift angle state.And conventional clamper is horizontal positioned, its center cannot keep concentric with drilling rod, and conventional clamper slips is difficult to block drilling rod, when equipment operation, also can clash into clamper because of boring vibration of bar, can cause drill pipe wear even to fracture when rotating speed is too high.
In practice, the method for depending merely on padding cannot keep angle stable.
What at present, probing field was conventional does not all relate to the problem of clamper and drilling rod blessing angle as wooden horse clamper, hydraulic gripper, deadweight type clamper etc.In fact, up to now, also do not have or seldom for the achievement in research of clamper and drilling rod clamping angle.
Given this, the utility model is intended to propose a kind of stepless variable-angle type clamper, by improving holder structure, makes clamper can realize stepless angle.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of stepless variable-angle type drill pipe clamp is provided, and this clamper can be realized clamper center and keep concentric with drilling rod, clamping ability is strong, meet the requirement of clamping, and simple in structure, and operation and maintenance is convenient.
The technical scheme providing according to the utility model, a kind of stepless variable-angle type drill pipe clamp, have the slips body for holding drill pipe, slips body is with sliding skeleton being installed in rotary body groove, and rotary body is arranged on luffing angle on base by slider-crank mechanism can realize electrodeless adjustment; Pedal is equipped with in rotary body side, and pedal is hinged on rotary body and by pedal locating ring and is located by pedal bearing pin.
The utility model beneficial effect is that holding structure is stable, prevents bearing pin generation lateral displacement.
On the bearing pin being particularly connected between jack and base, oscillating bearing is housed, bearing capacity is stronger, and can be tilted in certain angle scope.

Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As Figure 1-3, this stepless variable-angle type drill pipe clamp, it comprises base 1, repacking jack 3, rotary body 5, pedal 9 and slips body 11.The lower ear of repacking jack 3 is hinged by bearing pin 2 and the fixed-hinged support ear of base 1, rotary body 5 is hinged by bearing pin 10 ears with base 1, the upper ear of repacking jack 3 is connected by bearing pin 24 with rotary body, and the cottor pin 12 of pegging graft on bearing pin two, base 1, repacking jack 3 and the rotary body 5 threes formation slider-crank mechanism that is connected through the hinge; Pedal 9 is hinged by pedal bearing pin 7 with rotary body 5, locates by pedal locating ring 6; Be installed in rotary body 5 grooves with the slips body 11 of slip skeleton.
Base is the base plate that is welded with large and small each 2 fixed ear bases, is welded with the cramping body that is welded with a guide strip on 6 ear seats, narrow side plate on the base plate of rotary body and side plate, and pedal is made up of seesaw and skeleton round steel, slips body band rolling skeleton.
Repacking jack 3 two ends connect ear and lower ear, can be connected with base and rotary body by bearing pin.
The cottor pin 12 of pegging graft on the bearing pin that rotary body 5 and repacking are connected between jack 3.
Oscillating bearing 13 when being connected by bearing pin, the repacking lower ear of jack 3 and the ear seat of base 1 is installed.
Angular adjustment: first tear next repacking jack (because two jack are difficult to accomplish synchronization telescope) open, extract a jack and be connected latch on bearing pin with base, after extract a bearing pin 2; Then regulate repacking jack to elongate or shorten, for repacking jackscrew, the self-locking direction of adjustable screw jack ratchet, control jack elongates or shortens, then rotating ratchet is realized the flexible of jack, and rotary body rotates around hinged-support along with the flexible of jack, completes Angulation changes; Finally mixing up (vertical with drilling rod) behind required angle of slope, regulating the length of previously having pulled down jack to current installation dimension, plugging bearing pin and complete angular adjustment.
