Abstract
The invention discloses a novel unscrewing tong for a drill stem. The novel unscrewing tong comprises a movable jaw and a fixed jaw. An inner jaw part of the movable jaw comprises an engagement end face designed into a plane and an inner clamping face designed into an arc-shaped concave surface. The plane where an opening of the inner clamping face is located forms an included angle being 65-80 degrees with the engagement end face. The rear end of the movable jaw is hinged to the fixed jaw. The fixed jaw comprises a tong head and tong arms on the two sides. The tong head is fixedly clamped between the two tong arms. The rear end of the movable jaw is hinged between the two tong arms through a pin shaft. A mounting block is arranged between the two tong arms. A spring piece is fixedly mounted on the mounting block. The rear end of the movable jaw is provided with an arc-shaped convex surface. When the movable jaw rotates around the pin shaft, the arc-shaped convex surface at the rear end of the movably jaw makes contact with the spring piece to bend or unfold the spring piece. The novel unscrewing tong for the drill stem is wide in application range and high in operability and is expected to completely replace traditional chain tongs and pipe tongs in the near future.

Description of the drawings
Fig. 1 is the structural representation that drilling rod of the present invention is clamped with new unloading；
Top views of the Fig. 2 for Fig. 1.
Specific embodiment
With reference to embodiment and its Fig. 1-2, the invention will be further described, following examples be it is descriptive, no
It is determinate, it is impossible to which protection scope of the present invention is limited with this.
As shown in Figure 1-2, Fig. 1 is the structural representation that drilling rod of the present invention is clamped with new unloading, and Fig. 2 is the top view of Fig. 1.
A kind of drilling rod is clamped with new unloading, including moving jaw 1 and regular jaw 2；1 endognath of the moving jaw includes setting
The occlusion end face 3 for counting into plane and the clamping inner face 4 for being designed to arc-shaped concave, the opening place plane of the clamping inner face 4 is (i.e.
Line place plane between two openends of arc-shaped concave) it is 65 °～80 ° with the angle being engaged between end face 3, the work
The rear end of movable clamp port 1 is hinged on regular jaw 2；The regular jaw 2 includes the clamp handle 6 of binding clip 5 and both sides, and binding clip 5 is fixed
It is clamped between two clamp handles 6, the rear end of the moving jaw 1 is hinged between two clamp handles 6 by bearing pin 7, clamps at two
Mounting blocks 8 are set between handle 6, spring leaf 9 on mounting blocks 8, is fixedly mounted, the rear end of the moving jaw 1 have arc convex,
The moving jaw 1 around bearing pin 7 rotate when, the arc convex contact spring piece 9 of 1 rear end of moving jaw make spring leaf 9 bend or
Launch.
Ratchet, the moving jaw 1 are provided with 2 corresponding jaw endognath face of the moving jaw 1 and regular jaw
The ratchet incline direction on ratchet incline direction and 2 endognath face of regular jaw on endognath face is conversely, the inclination angle of the ratchet
Spend for 17 °～26 °.
Teeth are provided with the arc convex of 1 rear end of the moving jaw, the corresponding machine-shaping on spring leaf 9 has
With the intermeshing teeth of teeth on moving jaw 1.
Preferably, the both sides of spring leaf 9 are folded upward at forming gathering sill 10 so that spring leaf 9 and 1 rear end of moving jaw
Coordinate during arc convex intermeshing motion and be closely difficult slippage, play a part of guiding.
The spring leaf 9 be siderochrome cobalt FeCrCo magnet springs piece 9, the tooth on 1 rear end arc convex of the moving jaw
Tooth is siderochrome cobalt FeCrCo magnetic teeth.
6 middle setting of described two clamp handles has a metal connecting sheet 11, and the metal connecting sheet 11 is carbon steel steel bar, the gold
Category connection sheet 11 is welded in the middle of two clamp handles 6 to improve spanner bulk strength.In addition, between clamp handle opening and gap is equal
Envelope is filled out with carbon fibre composite bonding, to mitigate the weight of unloading pincers.Simultaneously in order to increase torque, can cover in clamp handle 6
It is sleeved.
The regular jaw 2 and moving jaw 1 are pack alloy YZAlSi9Cu4 or carbon steel (is selected according to actual needs
With different raw materials, mainly it is thought of as ensureing that the intensity of jaw is enough) casting.During reality processing, general activity
The finished product form of jaw 1 is also similar to that the building form of regular jaw 2, by two panels pack alloy YZAlSi9Cu4 or carbon steel
A block middle piece is clamped in the middle of the alloy sheet of casting, is bolted together.Middle can equally be die casting aluminium
Alloy Y ZAlSi9Cu4 or cast carbon steel shaping, it is also possible to be molded from other metal materials, for example, middle adopted on the whole
Siderochrome cobalt FeCrCo materials are molded the magnetic and spring leaf between and coordinate.
Ratchet on moving jaw 1 and regular jaw 2 is that welding-on is molded on its endognath face, and the material of the ratchet is
YG11C hard alloy.
On the ratchet, surfacing YMD451-4 type abrasion-resistant welding wire forms wearing layer.
The operation principle of this unloading pincers：
When being clamped using the unloading, first moving jaw 1 is broken into two with one's hands with hand (if necessary also can be by other external force), rod member is put
Enter jaw, moving jaw 1 is critical under the elastic force effect of spring leaf 9 rod member automatically, and rod member is because of the activity of linking closely when rotation unloading is clamped
Ratchet on jaw 1 and regular jaw 2 and unlikely slippage.When unloading pincers worker is made, torque Jing vice body rear end reaches vice body front end and makees
On rod member, position of mainly having an effect is the front end of regular jaw 2, and what cooperation was had an effect and acted primarily as fixation is activity
1 front end of jaw.Moving jaw 1 and the angle of inclination of the ratchet on regular jaw 2 are designed as 17 °～26 °, are engaged end face with folder
It is in order to clamp rod member, if from fractograph analysis, rod member exists to hold the purpose that angle between the plane of inner face opening place is 65 °～80 °
It is formed slopely with ratchet on moving jaw 1 and regular jaw 2 under the envelope of the occlusion end face 3 and clamping inner face 4 of moving jaw 1
Adjacent two it is domatic between high point to rod member formed interlocking, the class between moving jaw 1 and regular jaw 2 and rod member is put down
Face contact transformation is Multi-contact, and the increasing friction force in breakout process is more beneficial for fixed beam.1 rear end of moving jaw with
Spring leaf 9 is designed as siderochrome cobalt FeCrCo magnetic materials, can constantly keep close linear contact lay, and flexible rotation and can reducing is rubbed
Damage.
Forced blasting treatment is carried out to the appearance of whole unloading pincers, material is common quartz sand (SiO2>=88～
99.8%, Fe2O3≤ 0.06～0.005%, 1750～1800 DEG C of refractoriness, outward appearance particle are uniform, and granularity is 1～3MM, pure white
Color), roughness should meet GB/T13288 in R/z=60um～80um《Evaluation (the ratio of steel surface roughness grade number before application
Compared with sample block method)》.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any those familiar with the art the invention discloses technical scope in, the change or replacement that can be readily occurred in,
Should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of claims
Enclose and be defined.
