Description

A kind of all-purpose bit cassette holder

Technical field

This utility model belongs to petroleum drilling and mining equipment manufacturing technical field, relates to a kind of all-purpose bit cassette holder.

Background technology

Drill bit cassette holder is for meeting the turntable structure form of bearing pin drive balls square bushing and to design, tradition Four pin drill bit boxes, box and seat are separate structure, and structure needs simplification badly, and for each specifications and models Drill bit should distribute a cubic drill bit box, in drilling process, bit size is had not by drilling technology Same requirement, completes a bite well and must frequently change different size drill bit, and various sizes of drill bit should have correspondence Unique specification cassette holder on unload drill bit.Therefore cassette holder as deposit drill bit, on unload the auxiliary equipment of drill bit, Utilization rate in drilling process is the highest, need to frequently change, so cause four directions drill bit box specification and Quantity gets more and more, and not only occupies limited drilling floor surface space, also reduces work during shackle simultaneously Make efficiency.

Utility model content

The purpose of this utility model is to provide a kind of all-purpose bit cassette holder, solves prior art specification sum Amount is more and more, not only occupies limited drilling floor surface space, also reduces shackle work efficiency simultaneously Problem.

This utility model be employed technical scheme comprise that, a kind of all-purpose bit cassette holder, including cassette holder and lid, The face plate center of lid has the notch of three semi arch lobe compositions, and the bottom surface of cassette holder is fixedly installed four Bearing pin, the above tetragonal cylinder for hollow of cassette holder, the corner of this square cylinder is all by one Facet transition connects, and the facet at each angle the most uniformly has row's unthreaded hole；The corner of lid Transition is provided with an adjusting rod respectively, and each adjusting rod the most uniformly has multiple screw Hole；When cassette holder and lid snapping, the inner surface facet at each adjusting rod and each angle is close to, Mei Geguang Hole is connected to a securing member with the screw hole of correspondence position.

All-purpose bit cassette holder of the present utility model, is further characterized in that:

The size of four bearing pins is corresponding supporting with the counterbore size on rotating disk.

Three semi arch lobe sizes of lid face plate center and the profile assembling height and drill bit of adjusting rod Size correspondence is supporting.

The beneficial effects of the utility model are, compact conformation, owing to being furnished with the lid of different model, for The drill bit of different size model need not change whole cassette holder, need only change lid, the most not only improve Work efficiency during upper shackle has been also convenient for regulating the traffic；This general cassette holder also has well on using Superiority, it operationally has only to be arranged on by bearing pin in the standard counterbore of rotating disk.

Detailed description of the invention

With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, structure of the present utility model is, including cassette holder 2 With lid 3, the face plate center of lid 3 has the notch (see Fig. 3) of three semi arch lobe compositions, cassette holder The bottom surface of 2 is fixedly installed four bearing pins 1, the above tetragonal cylinder for hollow of cassette holder 2, should The corner of square cylinder all connects (such as Fig. 5 corner cut) by a facet transition so that this four directions Shape cylinder looks and is equivalent to one four big face and four little faces are spaced the octahedral column structure of composition successively；Often The facet at individual angle the most uniformly has row's unthreaded hole；The transition respectively of the corner of lid 3 is provided with one Individual adjusting rod 4, each adjusting rod 4 the most uniformly has multiple screw hole；Cassette holder 2 and box When covering 3 snapping, the inner surface facet at each adjusting rod 4 and each angle is close to, and each unthreaded hole is with corresponding The screw hole of position is connected to a securing member 5；All securing members 5 at four angles are by cassette holder 2 He Lid 3 is fixed together reliably.

Multiple passage is had so that when cassette holder 2 and lid 3 snapping on four walls of cassette holder 2 and base plate, Inner air and outer air can circulate.

With reference to Fig. 5, Fig. 6, Fig. 7, using method of the present utility model is,

Four bearing pin 1 lower ends of cassette holder 2 are installed in the counterbore that rotating disk is corresponding, thus are fixed by cassette holder 2 On drilling floor surface.Then the drill bit mentioned is consisted of three semi arch lobes of lid 3 face plate center Notch is put in drill bit box, and the notch of lid 3 face plate center can clamp the drill bit outer wall treating shackle, The most just can be by rotating shackle on rotating disk and wellhead hydraulic tong.

Operationally should coordinate with rotating disk due to drill bit box and also to mate with bit size, four bearing pins 1 Size corresponding supporting with the counterbore size on rotating disk, three semi arch lobe sizes of lid 3 face plate center Corresponding with the overall dimensions of drill bit supporting with the assembling height of adjusting rod 4.

Require and in upper shackle time institute because drill bit box is closed the different of bulk by different specification size drill bit The different moments of torsion needed, along with the moment of torsion required for the external diameter increase of drill bit increases the most therewith, drilling rod and brill Screwing force between Tou is very big, and this utility model utilizes drill bit box to be fixed by drill bit, big at rotating disk and hydraulic pressure Under the effect of pincers, the screw thread of drill bit and drilling rod departs from very convenient and laborsaving.
