Abstract
The content of the utility model mainly provides a wear-resisting anti-skidding drilling rod, its mainly used has the rig to bore the application of using to the drilling tool in the use, especially is arranged in the vertical hole to creep into and prevents that the drilling rod from slipping, is provided with the protruding structure of a plurality of on the excircle surface of drilling rod, increases the coefficient of friction between drilling rod surface and the pore wall through protruding structure to the centre gripping position through a plurality of protruding structure and rig produces frictional force, thereby makes the stability of drilling rod when creeping into safer.
Description
Technical Field
The invention mainly relates to a wear-resistant anti-slip drill rod which is mainly used for a drilling tool in the drilling use of a drilling machine, and is particularly used for preventing the drill rod from slipping in the vertical hole drilling.
Background
The suitable drilling tool product is the key for drilling implementation, when deep hole drilling is carried out, the drilling rod can be used for highlighting the advantages of the drilling rod according to different structures, due to the drilling requirement, when most underground drilling process is selected, the vertical roadway working surface can be used for drilling towards the roadway top wall, or the drilling at a certain inclination angle is carried out, when the drilling is carried out under the condition, the self weight of the drilling tool can reach thousands of kilograms when hundreds of connections are reached, the drilling resistance can be caused to the drilling machine to a certain extent, the drilling load is increased, the drilling rod can slide under the condition that the clamping part of the drilling machine is abraded, the drilling rod can slide off slightly carelessly, the high risk is achieved, and the personal safety of crisis workers is serious.
Disclosure of Invention
The invention provides a wear-resistant anti-skidding drill rod, wherein a plurality of protruding structures are arranged on the surface of the outer circle of the drill rod, the friction coefficient between the surface of the drill rod and the hole wall is increased through the protruding structures, and friction force is generated between the plurality of protruding structures and the clamping part of a drilling machine, so that the stability of the drill rod during drilling is safer.
In order to solve the problems, a plurality of convex structures are arranged on the surface of the wear-resistant anti-slip drill rod, and the expansion sections of the convex structures are circular.
In order to solve the problems, a plurality of protruding structures arranged on the surface of the wear-resistant anti-skidding drill rod are arranged in an equal sequence, a drill rod circle is used as a center in the radial direction, and a plurality of protruding structures in the radial direction are obtained after a plurality of protruding structures are arranged in a circumferential array.
The structure that a plurality of protruding structure that forms in radial direction shows through axial direction is for using the drilling rod axial as the basis, and a plurality of protruding structure carries out the permutation that the preface is greater than 2 array modes with axial direction to form even preface range structure and arrange around the body of rod.
After the surface of the drill rod is provided with a plurality of protruding structures, a groove which is communicated with each other can be formed between two adjacent protruding structures in the radial direction or the axial direction.
The depth of the convex structure on the surface of the drill rod is more than 1mm and less than 4mm, and the diameter of the circular structure of the cross section of the convex structure is more than 1mm and less than 20 mm.
The two ends of the drill rod are provided with an external connector and an internal connector which can be connected, the external connector is provided with an external thread connecting structure, and the interior of the external connector is provided with a limber hole; the inner connector is provided with an internal thread connecting structure, the inner part of the inner connector is also provided with a water through hole, and the outer connector and the inner connector are integrated with the rod body welding machine through friction welding.

Detailed Description
Reference is made to the figures contained in the accompanying drawings and in which is shown, by way of illustration and specific application, the following:
according to the figure, an outer connector 1 and an inner connector 2 are respectively welded at two ends of a drill rod body 3 of the wear-resistant anti-skid drill rod through friction welding, an external thread 101 is arranged on the outer connector 1, an outer water through hole 102 is arranged at the center of the inner part, an internal thread 201 is arranged on the inner connector 2, an inner water through hole 202 is arranged at the center of the inner part, and a friction welding inner turned edge 4 is generated after the friction welding.
The surface of the wear-resistant anti-skid drill rod is provided with a plurality of convex structures 301, and the unfolded sections of the convex structures are circular.
A plurality of protruding structures 301 that wear-resisting anti-skidding drilling rod's surface set up are the preface and arrange, use the drilling rod circular as the center in radial direction, and a protruding structure 301 carries out a plurality of and obtains a plurality of protruding structure 301 in radial direction after the circumference array of a plurality of.
The structure that a plurality of protruding structures 301 that form in radial direction showed through the axial direction is for using the drilling rod axial as the basis, and a plurality of protruding structures 301 arrange that the order is greater than 2 array modes with the axial direction to form even order arrangement structure and arrange around the body of rod.
After a plurality of convex structures 301 are arranged on the surface of the drill rod, through grooves 302 which are communicated with each other are formed between two adjacent convex structures 301 in the radial direction or the axial direction.
Any person should know that the structural changes made under the teaching of the present invention have the same or similar technical solutions as the present invention, and all fall into the protection scope of the present invention.
The techniques, shapes, and configurations not described in detail in the present invention are all known techniques.
