Abstract

The invention discloses an adjustable three-jaw chuck type gradiograph strengthening device. The strengthening device comprises an upper end cover, a lower end cover, a plurality of strengthening blocks, a big bevel gear and a small bevel gear, wherein the big bevel gear and the small bevel gear are fixedly arranged on the lower end cover; the strengthening blocks are arranged on the big bevel gear; the upper end cover is fixedly arranged on the lower end cover. The strengthening device provided by the invention mainly utilizes the clamping principle of a three-jaw chuck for machining, the small bevel gear is rotated for driving the big bevel gear to rotate so as to cause the strengthening blocks to simultaneously outward expand or shrink at same speed, so that the change in circumscribed circle diameters on the end faces of the strengthening blocks is realized, the strengthening blocks are in contact with the inner walls of drill hole, drill rod or sleeve and the axis of the gradiograph is almost consistent with the axis of the drilling hole. The adjustable three-jaw chuck type gradiograph strengthening device is simple in structure, convenient in mounting and dismounting, excellent in strengthening effect and suitable for drilling holes with different diameters; stepless adjustment is realized; the device is portable; a mud flow path is difficult to be blocked; the cost is saved; the service life of the strengthening device is prolonged; the strengthening device is also applicable to the strengthening of other tubing gradiographs.

Description

Technical field
The present invention relates to solid core drilling field, particularly one adjustable scroll chuck formula tiltmeter erection device.
Background technology
In investigation and prospecting, because complex formation, parameters of construction technology and human users are unreasonable etc., drilling track often off-design track, exceeds allowed band, and hole deviation occurs, and hole deviation can bring serious harmful effect to Geological Achievements and drilling operation.During prior art work, hole deviation may cause beating loses ore body, omit tomography, aggravation drill tool wear, cause drilling rod to fracture accident etc., in order to by deviation controlling in allowed band, be necessary in drilling process to measure hole deviation with tiltmeter, the diameter of tiltmeter is fixed, be merely able to the boring measuring a certain constant aperture, when bore diameter is excessive, needing to be equipped with corresponding erection device makes tiltmeter be in middle position, to ensure the accuracy of deviational survey result, the size of existing tiltmeter erection device is fixed, cannot use when bore diameter changes, therefore on-the-spot needs is equipped with the erection device overlapping different size diameter more, carry inconvenience, management and difficulty, cost increases, and existing erection device easily blocks mud flow channel, lowering velocity is slow, affect construction speed.
Summary of the invention
The size that the object of the invention is to solve above-mentioned existing tiltmeter erection device is fixed, cannot use when bore diameter changes, carry inconvenience, easy blocking mud flow channel, lowering velocity is slow, affect the problems such as construction speed, and a kind of adjustable scroll chuck formula tiltmeter erection device is provided.
The present invention is by upper end cover, bottom end cover, several wiper block, bevel gear wheel and bevel pinion composition, bevel gear wheel and bevel pinion are fixedly installed on bottom end cover, bevel gear wheel upper end has guide rail, bevel gear wheel lower end has teeth, the teeth of bevel gear wheel match with bevel pinion and arrange, several wiper block is arranged on bevel gear wheel, wiper block front end has wear-resistant block, wear-resistant block is fixedly installed on wiper block front end by trip bolt, wiper block lower end has guide ledges, bevel gear wheel upper end guide rail matches with guide ledges, upper end cover is fixedly installed on bottom end cover by several fastening bolt, upper end cover has the first through hole, several open slot and gathering sill, under wiper block clearance fit is arranged on gathering sill, bottom end cover has the second through hole,
Several wiper block becomes 120 ° to arrange with upper end cover axis;
Wear-resistant block outer ledge is arc-shaped.
Principle of work of the present invention and process:
During use, get two these identical devices, two these identical devices are fixedly installed on respectively the two ends up and down of tiltmeter, the upper end cover of one of them this device is screwed onto on deviational survey cable nipple, tiltmeter weight section is fixedly installed on the bottom end cover of another this device, after being all provided with, tiltmeter starts to measure hole deviation, the present invention mainly utilizes the clip principle of machining scroll chuck, bevel gear wheel is driven to rotate by rotating bevel pinion, moved radially in the gathering sill of upper end cover by guide ledges push-and-pull wiper block upper end, wiper block lower end, make that several wiper block is simultaneously synchronized to be expanded outwardly or shrink, realize the change of wiper block end face circumscribed circle diameter, be used for and boring, the contact internal walls of drilling rod or sleeve pipe, guarantee that axis and the drilling axis of tiltmeter are basically identical, improve the confidence level of deviational survey result, the wear-resistant block of the front end of wiper block, reduce tiltmeter wearing and tearing of wiper block in upper and lower process in hole, wear-resistant block is convenient to after damaging change, wear-resistant block outer ledge is arc-shaped, ensure and boring, the interior wall energy of drilling rod or sleeve pipe fully contacts, strengthen righting effect.
Beneficial effect of the present invention:
Structure of the present invention is simple, installation, convenient disassembly, righting is effective, is applicable to the boring of different pore size, realize electrodeless adjustment, easy to carry, not easily block mud flow channel, lowering velocity is fast, improve construction speed and work efficiency, save cost, extended the serviceable life of erection device, be also applicable to the righting of other tubing tiltmeter.
