Abstract
A sphere-cone-shaped gasket used for a drilling machine drill rod bolt connection comprises a spherical protruding gasket and a cone-shaped concave gasket, wherein the outer curved surface of the spherical protruding gasket is a spherical surface, and the inner curved surface of the cone-shaped concave gasket is a conical surface. The spherical protruding gasket is arranged in the cone-shaped concave gasket, the spherical surface of the spherical protruding gasket is matched with the conical surface of the cone-shaped concave gasket, and then a combined sphere-cone-shaped gasket is formed. In the process of installing and using, the spherical protruding gasket contacts with a nut, and the cone-shaped concave gasket contacts with a flange. When the drilling machine drill rod rotates and works, bending moment loaded by the screw is reduced by the relative motion of the concave surface and the protruding surface of the sphere-cone-shaped gasket, and the aim of reducing loaded stress of the screw is achieved. The sphere-cone-shaped gasket used for the drilling machine drill rod bolt connection is simple in structure, capable of reducing and even removing bending load of the screw, prolonging service life of the screw, and reducing drill dropping accidents.
Description
Technical field
The utility model relates to a kind of borer drill rod Bolt Connection ball taper 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 ball taper washer, between nut and flange, add a cover ball taper washer, relatively move to reduce the suffered moment of flexure of bolt by ball taper 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 taper cupped washer with the ball taper washer, the positive camber of spherical male packing ring is sphere, the negative camber of taper cupped washer is the conical surface, with the spherical male packing ring taper cupped washer of packing into, make the cone match of sphere and the taper cupped washer of spherical male packing ring, form a combination ball taper washer.When installing and using the spherical male packing ring is contacted with nut, the taper cupped washer contacts with flange, when the borer drill rod rotary work, utilize ball taper 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 the ball taper washer;
Fig. 2 is the application schematic diagram that the borer drill rod Bolt Connection is used the ball taper washer.
Marginal data:
1. spherical male packing ring, 2. taper cupped washer, 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 taper cupped washer 2 with the ball taper washer, the positive camber of spherical male packing ring 1 is sphere, the negative camber of taper cupped washer 2 is the conical surface, with the spherical male packing ring 1 taper cupped washer 2 of packing into, make the cone match of sphere and the taper cupped washer 2 of spherical male packing ring 1, form a combination ball taper washer.As shown in Figure 2, when installing and using spherical male packing ring 1 is contacted with nut 4, taper cupped washer 2 contacts with flange 5, when the borer drill rod rotary work, utilize ball taper 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 (2)
