Description
Technical field
The present invention relates to a kind of fishing device, is a kind of circulation drill screw bell specifically.
Background technology
Circulation drill is very extensive in Jingxi-Zhejiang-Shanghai area application.In the application process of circulation drill, fortuitous event is run into, drilling rod can be dropped in stake holes, salvage very troublesome.
The content of the invention
The purpose of the present invention, it is to propose a kind of delicate structure, the circulation drill screw bell of high-efficient homework.
To achieve the above object, technical solution of the invention is：
A kind of circulation drill screw bell, including spiral shape elbow and connecting rod, it is characterised in that：
The spiral shape elbow includes spiral shape termination and elbow, and spiral shape termination is spiral center, elbow such as crescent, and one end of elbow is merged with spiral shape termination, and the other end of elbow is tip；Spiral shape termination and elbow are in same plane, are made into integration by steel plate cutting；The inside arc of the crescent tip and the formation internal diameter of spiral shape termination,
Internal diameter is greater than the diameter of the drilling rod dropped in circulation drill drilling, but is less than the diameter of drilling rod fastener；For the outer arcuate of spiral shape elbow and crescent tip into external diameter, external diameter is less than circulation drill bore diameter；
The connecting rod is one section long 100cm straight-bars, and connecting rod material, diameter are provided with screw thread with salvaged circulation drill drilling rod, one end of connecting rod, and the other end and the spiral shape termination of connecting rod are welded and fixed, and connecting rod is vertical with spiral shape termination and elbow plane；
Circulation drill screw bell is additionally provided with screw rod and fastener, and the both ends of the screw rod are provided with screw thread, and one end and the circulation drill drilling rod spiral shell of screw rod connect, and the fastener is provided with internal thread, in screw rod（1）The other end and connecting rod between connection, fastening screw and connecting rod.
The circulation drill screw bell of the present invention can also be further achieved by the following technical measures.
Foregoing circulation drill screw bell, wherein the steel plate thickness 30mm.
After adopting the above technical scheme, the circulation drill screw bell of the present invention has advantages below：
1st, fisher is simple in construction, easy to make；
2nd, the efficiency for salvaging drilling rod is improved, ensures construction safety；
3rd, fisher can reuse, and save labour cost, reduce engineering cost.
Brief description of the drawings
Fig. 1 is the circulation drill screw bell structural representation of the embodiment of the present invention.
In figure：1 screw rod, 2 fasteners, 3 connecting rods, 4 fishing heads, 5 crescent tips, 6 crescent tips and the internal diameter of spiral shape termination, 7 crescent tip external diameters.
Embodiment
With reference to embodiments and its accompanying drawing illustrates further to the present invention.
Embodiment 1
Circulation drill, it is a kind of piling machinery.Its operation principle is to drive drill bit to rotate by drilling rod soil is worn into mud, and carries out direct circulation by mud and take soil so as to persistently creep into and pore-forming out of.Can drill straight footpath 600mm, 800mm, 1000mm stake holes.In construction, due to a variety of causes, drill bit can come off in hole, salvage cumbersome.In drill bit falling hole, the circulation drill screw bell of the present invention can be connected with borer drill rod, transfer in hole and rotate, treat that spiral shape elbow 4 has entangled the drilling rod on drill bit top（Diameter 89mm）, because there be a fastener on the head of drilling rod（A diameter of 99mm）, spiral shape elbow will block the fastener of drill bit, easy to operate effective so as to which drill bit is proposed in hole.
Referring now to Fig. 1, Fig. 1 is the circulation drill screw bell structural representation of the embodiment of the present invention.As illustrated, the spiral shape elbow 4 includes spiral shape termination and elbow, spiral shape termination is spiral center, elbow such as crescent, and one end of elbow is merged with spiral shape termination, and the other end of elbow is tip；Spiral shape termination and elbow are in same plane, are made into integration by steel plate cutting；The inside arc of the crescent tip and the formation internal diameter 6 of spiral shape termination, internal diameter are greater than the diameter of the drilling rod dropped in circulation drill drilling, but are less than the diameter of drilling rod fastener；For the outer arcuate of spiral shape elbow and crescent tip into external diameter 6, external diameter is less than circulation drill bore diameter；The steel plate thickness is 30mm.
The connecting rod 3 is one section long 100cm straight-bars, and connecting rod material, diameter are provided with screw thread with salvaged circulation drill drilling rod, one end of connecting rod, and the other end and the spiral shape termination of connecting rod are welded and fixed, and connecting rod is vertical with spiral shape termination and elbow plane；
Circulation drill screw bell is additionally provided with screw rod 1 and fastener 2, the both ends of the screw rod 1 are provided with screw thread, one end of screw rod connects with circulation drill drilling rod spiral shell, and the fastener 2 is provided with internal thread, connection, fastening screw 1 and connecting rod 3 between the other end and connecting rod of screw rod 1.
Embodiment 2
A kind of application method for circulation drill screw bell, comprise the following steps：
A, screw rod is connected with borer drill rod；
B, fisher is put into stake holes using rig；
C, fishing tool rotation is driven using stake machine；
D, the drilling rod dropped in stake holes can be blocked when fisher rotates；
E, fisher is above carried using rig；
F, the drilling rod dropped in hole is proposed into stake holes.
The present invention has substantive distinguishing features and significant technological progress, and circulation drill screw bell of the invention, screw bell is simple in construction, easy to make, screw rod 1 is connected with borer drill rod during use.The efficiency for improving and salvaging drilling rod is realized, drilling rod easily very can be salvaged into stake holes.
Above example is used for illustrative purposes only, rather than limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or change.Therefore, all equivalent technical schemes should also belong to scope of the invention, should be limited by each claim.
