Abstract
A cone-shaped attachment bolt assembly special for a drilling machine drill rod is composed of a cone-shaped bolt, a cone-shaped nut and two cone-shaped hole gaskets, wherein the hexagon head of the cone-shaped bolt and a bolt rod are in cone-shaped transition and are matched with the cone-shaped hole gaskets, the cone-shaped nut is provided with a cone-shaped body matched with the cone-shaped hole gaskets, and the cone-shaped hole gaskets are provided with cone-shaped holes which are respectively matched with the cone-shaped bolt and the cone-shaped nut. When the cone-shaped attachment bolt assembly is installed and used, the small-hole end faces of the cone-shaped hole gaskets are contacted to a flange, and the cone faces of the cone-shaped bolt and the cone-shaped nut and the cone faces of the cone-shaped hole gaskets are respectively matched and are connected through threads of the cone-shaped bolt and the cone-shaped nut. When the drilling machine drill rod conducts rotation work, loads borne by the cone-shaped bolt are improved through the cone-shaped structure, the stress concentration degree of the cone-shaped bolt is lowered, the purpose that concentration stress of the cone-shaped bolt is reduced is achieved, service life of the cone-shaped bolt is prolonged, and drill falling accidents are reduced.
Description
Technical field
The utility model relates to a kind of borer drill rod attachment bolt.
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, cause the bolt stress raisers, therefore bolt is not long working life, need 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 the special-purpose taper attachment bolt of a kind of borer drill rod assembly, improve the load that bolt bears by utilizing cone structure, alleviate the stress concentration degree of bolt, reach and reduce the suffered concentrated stress of bolt, make bolt strained more evenly, prolong working life of bolt, reduce the generation of falling the brill accident.
The technical solution adopted in the utility model is: the special-purpose taper attachment bolt of borer drill rod assembly is comprised of taper bolt, tapered cup nut and two cone shape hole packing rings.Pass through tapering transition between hexagon head on the taper bolt and the bolt shank, and cooperate with the cone shape hole packing ring; Tapered cup nut has a taper, cooperates with the cone shape hole packing ring; The cone shape hole packing ring has a cone shape hole, cooperates with taper bolt, tapered cup nut respectively.Aperture end face with the cone shape hole packing ring when installing and using contacts with flange, the conical surface of taper bolt and tapered cup nut respectively with the cone match of cone shape hole packing ring, by the scyewed joint on taper bolt and the tapered cup nut together, when the borer drill rod rotary work, utilize cone structure to improve the load that taper bolt bears, alleviate the stress concentration degree of taper bolt, reach the purpose that reduces the suffered concentrated stress of taper bolt.
Good effect of the present utility model is: simple in structure, the stress that reduces bolt is concentrated, and prolongs the working life of bolt, reduces the generation of falling the brill accident.
Description of drawings
Fig. 1 is the whole vertical profile structural drawing of the special-purpose taper attachment bolt of borer drill rod assembly.
Marginal data:
1. taper bolt, 2. tapered cup nut, 3. cone shape hole packing ring, 4. flange.
Embodiment
The utility model is described in further detail below in conjunction with Fig. 1:
As shown in Figure 1, the special-purpose taper attachment bolt of borer drill rod assembly is comprised of taper bolt 1, tapered cup nut 2 and two cone shape hole packing rings 3.Pass through tapering transition between hexagon head on the taper bolt 1 and the bolt shank, and cooperate with cone shape hole packing ring 3; Tapered cup nut 2 has a taper, cooperates with cone shape hole packing ring 3; Cone shape hole packing ring 3 has a cone shape hole, cooperates with taper bolt 1, tapered cup nut 2 respectively.Aperture end face with cone shape hole packing ring 3 when installing and using contacts with flange 4, the conical surface of taper bolt 1 and tapered cup nut 2 respectively with the cone match of cone shape hole packing ring 3, by the scyewed joint on taper bolt 1 and the tapered cup nut 2 together, in borer drill rod rotary work process, utilize cone structure to improve the load that taper bolt 1 bears, alleviate the stress concentration degree of taper bolt 1, reach the purpose that reduces taper bolt 1 suffered concentrated stress.
