Abstract
The utility model proposes a strength joint device of a major-diameter steel pipe, which can bear big drawing force and big torque. The strength joint device mainly comprises an upper segment of steel pipe, a lower segment of steel pipe and a screw, wherein a 50-200mm of inner spigot is arranged at the lower port of the upper segment of steel pipe; a 50-200mm of outer spigot is arranged at the upper port of the lower segment of steel pipe; the inner spigot is matched with the outer spigot; 1-2 circles of penetrable holes and corresponding screw holes are arranged on the inner and the outer spigots in a matching way, and the 4-20 penetrable holes and the corresponding screw holes are arranged at each circle; the lower end of the upper segment of steel pipe is fixedly connected with the upper end of the lower segment of steel pipe by the screw; and 2-8 location pins are arranged on external touch lines of the inner and the outer spigots. As the location pins and the special screws have the same quantity, the strength joint device can bear bigger drawing force and torque. The strength joint device has convenient operation and can be used repeatedly.
Description
Technical field
The utility model relates to the coupling device, particularly a kind of large diameter steel pipe piecing devices that can bear high pulling torque.
Background technology
In the building pile foundation construction or in the foundation construction of offshore platform, often need that large diameter steel pipe is inserted the stratum and make steel pipe pile usefulness, because insertion depth is big, can reach tens meters or darker, the steel pipe length of standard is very short, has only several meters or tens meters, needs many steel pipes to couple together, just can reach the length that needs, the method for use welding connects usually.For the steel pipe pile that does not need to pull up, it is feasible doing like this.But for the steel pipe pore-creating filling pile construction, the steel pipe under inserting must be pulled out from underground in segmentation, and construction is trouble very.With general conventional connected mode, because of powerful pulling capacity and torsion often can not bear, dismounting is also very inconvenient simultaneously.
The utility model content
The purpose of this utility model is to propose a kind of powerful piecing devices of large diameter steel pipe that can bear big pulling capacity, high pulling torque.
The utility model is to realize like this.It mainly is made up of upper and lower joint steel pipe and screw, process the female end of a 50～200mm in the lower port of last joint steel pipe, male end at a 50～200mm of upper port processing who saves steel pipe down, internal and external stopper matches, on internal and external stopper, join and make 1～2 circle, 4～20 perforation of every circle and corresponding screw, to go up the lower end of joint steel pipe with screw and fixedly connected, 2～8 alignment pins will be installed on the outer contacting line of internal and external stopper with the upper end of saving steel pipe down.
The course of work of the present utility model is such.Alignment pin is fixed on down in the upper end pin-and-hole of joint steel pipe earlier, slings and go up the joint steel pipe, aim at alignment pin, internal and external stopper is cooperated assemble up, couple together with a plurality of screw then with the semi-circle pin holes of its lower end.Earlier a plurality of screws are dismantled during dismounting, hang then and go on the joint steel pipe and get final product.
Because alignment pin and the screw number installed are more, so can bear more powerful pulling capacity and torsion.The utility model is easy to operate, can use repeatedly.

The specific embodiment
As seen from the figure, the utility model mainly is made up of upper and lower joint steel pipe and screw, process the female end of a 50～200mm in the lower port (1) of last joint steel pipe, male end at a 50～200mm of upper port (4) processing who saves steel pipe down, internal and external stopper matches, on internal and external stopper, join and make 1～2 circle, 4～20 perforation of every circle and corresponding screw, to go up the lower end of joint steel pipe with screw (2) and fixedly connected, 2～8 alignment pins (3) will be installed on the outer contacting line of internal and external stopper with the upper end of saving steel pipe down.
Claims (2)
1. powerful piecing devices of a large diameter steel pipe, it mainly is made up of upper and lower joint steel pipe and screw, it is characterized in that female end at a 50～200mm of lower port (1) processing of last joint steel pipe, male end at a 50～200mm of upper port (4) processing who saves steel pipe down, internal and external stopper matches, joining on internal and external stopper and make 1～2 circle, 4～20 perforation of every circle and corresponding screw, fixedlys connected with the upper end of following joint steel pipe in the lower end that will go up the joint steel pipe with screw (2).
2. the powerful piecing devices of a kind of large diameter steel pipe according to claim 1 is characterized in that installing 2～8 alignment pins (3) on the outer contacting line of internal and external stopper.
