Abstract
The utility model discloses a joint special for butting rail steel pipes with equal diameters. The joint comprises a positioning pin and an opening positioning baffle sheet; the positioning pin comprises guide conical surfaces, positioning cylindrical surfaces and a positioning baffle sheet clamp groove; the opening positioning baffle sheet is arranged in the positioning baffle sheet clamp groove; the guide conical surfaces are used for guiding the positioning cylindrical surfaces to enter the inner holes of the rail steel pipes smoothly to ensure that two rail steel pipes to be butted are integrally connected at the accurate coaxiality, and the outer diameters of the two rail steel pipes to be butted are smooth; and the opening positioning baffle sheet is used for controlling the length of the positioning cylindrical surfaces entering the inner holes of the rail steel pipes, and guaranteeing that the port of the two rail steel pipes to be butted is provided with a gap which meets the requirement of a welding process. The joint has the advantages of ensuring the coaxiality accuracy of the outer diameters of the two rail steel pipes to be butted and guaranteeing that the gap of the port of the two rail steel pipes to be butted meets the requirement of the welding process.
Description
Technical field
The utility model relates to a kind of joint technology of isometrical steel pipe butt joint, relates in particular to a kind of isometrical track steel pipe butt joint special joint.
Background technique
In the prior art; The butt joint of isometrical steel pipe; All adopt the method that increases interim backer to guarantee the smooth connection of outer diameter of steel pipes, the shortcoming of this docking calculation is: can not satisfy the needs of the demanding isometrical steel pipe butt joint of coaxial accuracy of docking port, the butt joint of for example isometrical track steel pipe.
The model utility content
In order to solve the problems referred to above that exist in the existing technology; The utility model provides a kind of isometrical track steel pipe butt joint special joint; Not only can guarantee the coaxial precision of two docking orbit outer diameter of steel pipes, and can also guarantee that the interface gaps of two docking orbit steel pipes meets welding process requirement.
The utility model is through adopting following technological scheme to realize.
Design a kind of isometrical track steel pipe butt joint special joint, said isometrical track steel pipe butt joint special joint comprises: locating stud, opening locating stop piece; Said locating stud comprises guiding conical surface, positioning cylindrical surface and locating stop piece draw-in groove; Said opening locating stop piece comprises locating face, opening; Said opening locating stop piece is installed in the locating stop piece draw-in groove.
The effect of the opening of said opening locating stop piece is to be convenient to said opening locating stop piece is packed in the said locating stop piece draw-in groove.
The effect of the guiding conical surface of said locating stud is the guiding positioning cylindrical surface endoporus of injection steel pipe successfully; The effect of the locating face of said locating stop piece is the length of control positioning cylindrical surface injection steel tube inner hole.
The combination of said positioning cylindrical surface and two elements of fix of said locating face; The track steel pipe that guarantees two butt joints links into an integrated entity with accurate coaxality; Make the track outer diameter of steel pipes of two butt joints level and smooth, and guarantee that the jointing of two docking orbit steel pipes leaves the gap that meets welding process requirement.
