Abstract
A spherical washer for connection of a bolt of a drill rod of a drilling machine is composed of a spherical convex washer and a spherical concave washer, the outer curved surface of the spherical convex washer is a spherical surface, the inner surface of the spherical concave washer is a spherical surface, the spherical convex washer is installed into the spherical concave washer, and the spherical surface of the spherical convex washer is matched with the spherical surface of the spherical concave washer to form the combined spherical washer. When the spherical washer is install for use, the spherical convex washer contacts a nut, and the spherical concave washer contacts a flange; and when the drill rod rotates to work, the bending moment borne by the bolt is eliminated by means of relative motion of the convex surface and the concave surface of the spherical washer, and the purpose that stress borne by the bolt is reduced is achieved. The spherical washer is simple in structure, can reduce or even eliminate the bending moment borne by the bolt, prolongs the service life of the bolt, and reduces the accidents of drill falling.
Description
Technical field
The utility model relates to a kind of borer drill rod Bolt Connection spherical washer.
Background technique
The connection of borer drill rod adopts the bolt group that the drilling rod flange is directly connected traditionally, bolt bearing tension but also bear moment of flexure not only in the using process, therefore bolt is not long working life, needs often to change bolt, otherwise can cause bolt fracture and then initiation to fall the brill accident.
Summary of the invention
Deficiency for above-mentioned technology existence, the utility model provides a kind of borer drill rod Bolt Connection spherical washer, between nut and flange, add a cover spherical washer, relatively move to reduce the suffered moment of flexure of bolt by the spherical washer male and fomale(M﹠F), make bolt strained more even, prolong the working life of bolt, reduce the generation of falling the brill accident.
The technical solution adopted in the utility model is: the borer drill rod Bolt Connection is comprised of spherical male packing ring and spherical female packing ring with spherical washer, the positive camber of spherical male packing ring is sphere, the negative camber of spherical female packing ring is sphere, with the spherical male packing ring spherical female packing ring of packing into, the sphere of spherical male packing ring is cooperated with the sphere of spherical female packing ring, form a combined spherical packing ring.When installing and using the spherical male packing ring is contacted with nut, the spherical female packing ring contacts with flange, when the borer drill rod rotary work, utilize the spherical washer male and fomale(M﹠F) relatively move reduce the suffered moment of flexure of bolt, reach the purpose that reduces the suffered stress of bolt.
Good effect of the present utility model is: simple in structure, can reduce even eliminate the flexural load that bolt bears, and prolong the working life of bolt, reduce the generation of falling the brill accident.
Description of drawings
Fig. 1 is the whole vertical profile structural drawing that the borer drill rod Bolt Connection is used spherical washer;
Fig. 2 is the application schematic diagram that the borer drill rod Bolt Connection is used spherical washer.
Marginal data:
1. spherical male packing ring, 2. spherical female packing ring, 3. bolt, 4. nut, 5. flange.
Embodiment
The utility model is described in further detail below in conjunction with Fig. 1, Fig. 2:
As shown in Figure 1, the borer drill rod Bolt Connection is comprised of spherical male packing ring 1 and spherical female packing ring 2 with spherical washer, the positive camber of spherical male packing ring 1 is sphere, the negative camber of spherical female packing ring 2 is sphere, with the spherical male packing ring 1 spherical female packing ring 2 of packing into, the sphere of spherical male packing ring 1 is cooperated with the sphere of spherical female packing ring 2, form a combined spherical packing ring.As shown in Figure 2, when installing and using spherical male packing ring 1 is contacted with nut 4, spherical female packing ring 2 contacts with flange 5, when the borer drill rod rotary work, utilize the spherical washer male and fomale(M﹠F) relatively move reduce bolt 3 suffered moments of flexure, reach the purpose that reduces bolt 3 suffered stress.
Claims (1)
1. borer drill rod Bolt Connection spherical washer, it is characterized in that: formed by spherical male packing ring (1) and spherical female packing ring (2), spherical male packing ring (1) the spherical female packing ring (2) of packing into, the sphere of spherical male packing ring (1) is cooperated with the sphere of spherical female packing ring (2), form a combined spherical packing ring.
