Abstract
The utility model discloses an octagonal embedded joint, which comprises a drill stem (1), wherein one end of the drill stem is fixedly connected with an external octagonal joint (3), and the other end of the drill stem is fixedly connected with an internal octagonal joint (5); pin holes (4) are formed in the radial directions of the external octagonal joint (3) and the internal octagonal joint (5); and pins (2) are detachably arranged in the pin holes. The octagonal embedded joint has a simple structure; by adopting an octagonal embedded connection mode, quick connection of the drill stem and improvement of output torque are realized, and the working efficiency is increased; compared with the conventional drill, the drill has the advantages that: the torque is improved; the connection is more convenient and faster; and the requirements of quick connection and large torque transfer of a long-screw drilling pile driver and a screw stem pile driver drill stem are met.
Description
Technical field
The utility model belongs to the constructional engineering machinery field, relates to a kind of anistree embedded joint of drilling rod.Applying to rotary drilling rod rig, spiral drilling machine and the quick of drilling rod such as screw rod stake machine and helical burr ram machine is connected.
Background technology
Traditional rotary drilling rod rig and spiral drilling machine connect generally to adopt at the two ends of drilling rod and connect by bolt with flange, its set-up time is longer, and the flat key in the middle of the flange weares and teares bigger under the rotation torque effect of long period, tend to occur bigger distortion and bolt looseness, cause the drilling tool spillage that leaks, and dismantle time-consuming taking a lot of work.
Along with the domestic construction floor constantly develops to high-rise, superelevation layer, construction depth to stake constantly extends, present spiral drilling machine drilling rod pile machine equipment drilling tool is not complementary in flange connected mode and modernized form of construction work high-rise, superelevation layer traditional drilling tool in constructing, what is more, bring hidden danger to workmanship.
In order to satisfy the requirement of modernized form of construction work, make spiral drilling machine, screw rod stake machine and helical burr ram machine drill bar pile machine equipment drilling tool improve output torque and reduce labor intensity, improve work efficiency, developing a kind of tool joint that drilling rod is connected fast and transmit than high pulling torque has become problem demanding prompt solution.
The utility model content
The purpose of this utility model is to provide a kind of anise embedded joint at the deficiencies in the prior art, adopt anistree embedded connected mode, realize the quick connection of drilling rod and improved output torque, improve work efficiency, make its drilling tool improve bigger moment of torsion and connect convenient and quick than traditional drilling tool.
The technical scheme that the utility model adopted:
The embedded joint of a kind of anise comprises drilling rod, and an end of drilling rod connects firmly outer anistree joint, and the other end connects firmly interior anistree joint, anistree outside joint, interior anistree joint radially offer pin-and-hole, the detachable latch that is provided with on pin-and-hole.During connection, the outer anistree joint of a joint drilling rod is inserted in interior anistree joint of another joint drilling rod, insert pin-and-hole with latch in the middle of anistree outside then joint and the interior anistree joint, thereby between drilling rod and drilling rod, form Embedded temporary fixed the connection; During dismounting, only need pull out the connection that latch gets final product dismounting drilling rod, thereby realize the quick connection of drilling rod, the purpose of dismounting.
The utility model is simple in structure, adopt anistree embedded connected mode, realize the quick connection of drilling rod and improved output torque, improve work efficiency, make its drilling tool improve bigger moment of torsion than traditional drilling tool and connect convenient and quick, the quick connection and the requirement of transmitting large torque that is applicable to realization long auger stake machine and screw rod stake machine drill bar.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, drilling rod; 2, pin; 3, outer anistree joint; 4, pin-and-hole; 5, interior anistree joint.
The specific embodiment
In the structure shown in the figure, the utility model comprises drilling rod 1, and an end of drilling rod connects firmly outer anistree joint 3, and the other end connects firmly interior anistree joint 5, anistree outside joint 3, interior anistree joint 5 radially offer pin-and-hole 4, the detachable latch 2 that is provided with on pin-and-hole.
During connection, the outer anistree joint 3 of one joint drilling rod is inserted in the interior anistree joint 5 of another joint drilling rod, insert pin-and-hole 4 with latch 2 in the middle of anistree outside then joint and the interior anistree joint, thereby between drilling rod and drilling rod, form Embedded temporary fixed the connection, because connecting portion adopts anistree structure, convenient quick contraposition, its anistree face contact area is big, makes the maximum opposing moment of torsion of the moment of torsion of transmission greater than the drilling rod section; During dismounting, only need pull out the connection that latch gets final product dismounting drilling rod, thereby realize the purpose of quick connection, dismounting and the transmitting large torque of drilling rod.
Claims (1)
1. embedded joint of anise, it is characterized in that: comprise drilling rod (1), an end of drilling rod connects firmly outer anistree joint (3), and the other end connects firmly interior anistree joint (5), anistree outside joint (3), interior anistree joint (5) radially offer pin-and-hole (4), the detachable latch (2) that is provided with on pin-and-hole.
