Abstract
The utility model relates to a drilling rod connected through a rectangular taper pin shaft, which belongs to the technical field of machineries of construction piling projects. The technical scheme includes an upper drilling rod, a lower drilling rod, a connecting spline and a pin shaft (3). The ends of the upper drilling rod and the lower drilling rod are respectively provided with a male connector (5) and a female connector (1) which are mutually matched and are connected together through the connecting spline. The male connector and the female connector are fixed through the pin shaft which has a rectangular cross section. The drilling rod has the advantages of being not easy to deform, capable of improving sealing performance, convenient to install and the like. The problems in rigidity, strength and sealing performance are well resolved, and the drilling rod is quick and convenient in mounting and dismounting, greatly lowers working intensity of workers and is a drilling rod connecting device with popularization value.
Description
Technical field
The utility model relates to a kind of drilling rod that adopts rectangle taper pin axle to connect, and belongs to building pile works field of mechanical technique.
Background technology
At present, the drilling rod of building pile works machinery mainly adopts round pin axle mode to connect, and for example: Chinese patent CN01213174.1 adopts circular bearing pin to connect exactly.The subject matter that background technology exists is: because connected mode is unreasonable, easy deformation removes and installs very difficulty.
The utility model content
The purpose of this utility model provides a kind of drilling rod that adopts rectangle taper pin axle to connect, and by the profile change of bearing pin and fitting face, eliminates external force, can not be out of shape, and convenient disassembly solves the problems referred to above that background technology exists.
The technical solution of the utility model is:
A kind of drilling rod that adopts rectangle taper pin axle to connect, comprise drilling rod, following drilling rod, connect spline, bearing pin, last drilling rod and following drill rod end are respectively equipped with male joint, the female joint of mutual coupling, link together by connecting spline each other, be provided with bearing pin between male joint, the female joint and fix, said bearing pin is the square-section bearing pin.
Said square-section bearing pin wherein at least one mask has tapering, can easierly insert.
Male joint and bearing pin junction are circular groove shape, and bearing pin can be inserted in the past in angle arbitrarily.The utility model is provided with bolt, and female joint and bearing pin are linked together.
The utility model also is provided with seal between male joint, female joint.
Good effect of the present utility model is: the utlity model has be not easy the distortion and also can improve sealing performance, advantage such as easy for installation, rigidity, intensity, sealing all obtain fine solution, and dismounting is rapid, convenient, having alleviated working strength of workers greatly, is a kind of drilling rod linkage with promotional value.
