Abstract
The utility model relates to a drill rod, comprising a drill rod body, wherein one end of the drill rod body is provided with an inner joint, the other end of the drill rod body is provided with an outer joint, the inner joint and the outer joint are respectively provided with a pin hole in a radial direction, the outer joint of one section of the drill rod body is inserted into the inner joint of the other section of drill rod body in a manner of inserting a pin into the corresponding pin hole for fixed connection, each inner joint is an inner octagonal joint, and each outer joint is an outer octagonal joint. The drill rod is convenient and rapid to connect and dismount, has the cross section being strong in shear-bearing capacity, is high in transmitted torque, and can be widely applied by being mounted on a screw piling machine and a long spiral piling machine.
Description
Technical field
The utility model relates to a kind of drilling rod, is applicable to be installed on screw rod stake machine and the long screw pile machine to use.
Background technology
Drilling rod is used to connect the rig landscape apparatus and is positioned at drilling well bottom brill mill equipment or bottom outlet device.The purposes of drilling rod is that drilling mud is transported to drill bit, and improves, reduces or rotate the bottom outlet device with drill bit.Drilling rod must be able to bear huge interior external pressure, distortion, bending and vibration.Getting well with bad of tool joint determined the application life of drilling rod to a certain extent.
Application number is that the utility model patent of CN201020217800.6 discloses a kind of hex union drilling rod; It mainly comprises the drilling rod main body, and drilling rod body axis direction is provided with helical blade, and drilling rod main body one end is provided with hexagonal shoulder nipple; The other end is provided with the outer-hexagonal joint; Hexagonal shoulder nipple and outer-hexagonal joint directly upwards are respectively equipped with pin-and-hole, and the outer-hexagonal joint of a joint drilling rod main body inserts in the hexagonal shoulder nipple of another joint drilling rod main body, and the centre is inserted pin-and-hole with pin and is fixedly connected.Yet because its cross section shear resistance is not enough, so transfer torque is less.
The utility model content
It is stronger that the technical problem that the utility model solves provides a kind of joint cross section shear resistance, the drilling rod that transfer torque is bigger.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of drilling rod comprises the drilling rod main body, the spigot that drilling rod main body one end is provided with; The socket that the drilling rod main body other end is provided with; Spigot and socket directly upwards are respectively equipped with pin-and-hole, and the socket of a joint drilling rod main body is inserted in the spigot of another joint drilling rod main body, and the centre is inserted pin-and-hole with pin and is fixedly connected; Said spigot is an interior all directions joint, and said socket is outer joint from all directions.
Said drilling rod body axis direction is provided with helical tooth.
The all directions joint is the 35# steel with outer joint material from all directions in said.
Said drilling rod material of main part is the Q235 steel
Said helical tooth is a foundry goods, and material is ZG270-500.
The beneficial effect of the utility model is its connection and convenient disassembly, quick, and joint cross section shear resistance is strong, and transfer torque is big, can be installed on screw rod stake machine and the long screw pile machine to be widely used.
Description of drawings
Further specify below in conjunction with accompanying drawing and the specific embodiment technical scheme the utility model.
The structural representation of the drilling rod that Fig. 1 provides for the utility model embodiment.
The specific embodiment
The drilling rod of screw rod stake machine as shown in Figure 1; The interior joint 1 from all directions of the one end welding of its drilling rod main body 2, the outer joint 4 from all directions of the other end welding of drilling rod main body 2, interior all directions joint 1 and outer joint from all directions 4 footpaths upwards are respectively equipped with pin-and-hole 5; The outer all directions joint 4 of one joint drilling rod main body inserts in the interior all directions joint 1 of another joint drilling rod main body; Middle with 5 fixed connections of pin insertion pin-and-hole, interior all directions joint 1 is the 35# steel with outer joint 4 materials from all directions, and the material of drilling rod main body 2 is the Q235 steel; Be welded with helical tooth 3 on the drilling rod body axis direction, the material of helical tooth 3 is ZG270-500.
The connection of present embodiment and convenient disassembly, quick, joint cross section shear resistance is strong, and transfer torque is big.
It should be noted last that; The above specific embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
