Abstract
The utility model relates to a drill rod for rotary drill, relating to a fitting for rotary drill. The utility model comprises an inner rod. Segment tubes which are layer-layer sleeved with each other is arranged outside the inner rod. The segment tube comprises a tube body. The surface of the tube body is provided with a tendon strip. One end of the tube body is provided with a driving sleeve while the other end is provided with a positioning sleeve. An edge circle is arranged between the positioning sleeve and the tube body. The edge circle of the inner segment tube is assorted with the driving sleeve of the outer segment tube. The utility model has the advantages of rational structure, adopting a tooth shape structure of the tendon strip which overcomes the shortcomings of a plurality of welding seams, easy deformation, low mechanical intensity of the primary structure, and increasing the mechanical intensity of the product. A movable edge circle is arranged at the lower end of the positioning sleeves of the segments except the first segment of the drill rod, thereby avoiding the direct friction between the driving sleeve and the positioning sleeve, prolonging the service time of the driving sleeve and the positioning sleeve, and solving the problem that the lock rod and the positioning sleeve are easy to fall off.
Description
Technical field
The utility model relates to a kind of accessory of rotary drilling rig.
Background technology
Rotary drilling rig in the engineering construction process, the length of its drilling rod need adjust according to construction requirement, thus different in size, adopt the method for more piece rod tube layer overlaps and clamping usually.Because in the course of the work, combined stresseses such as drilling rod can bear shearing simultaneously, reverses, pressurization, so in work progresss such as speedway, railway, bridge, highrise building, actuating sleeve of the prior art upper end directly contacts and produces friction with the positioning sleeve lower end, serious friction between work a period of time rear drive cover and the positioning sleeve, can cause the generation of kelly phenomenon, welding position, positioning sleeve lower end weares and teares fully when more serious, cause positioning sleeve to come off, cause drilling rod to be fallen in the hole, salvage difficulty, influence the progress of engineering construction.
The utility model content
The utility model purpose provides a kind of rotary drilling rig drilling rod of rational in infrastructure, long service life.
The utility model comprises interior bar, interior bar is provided with the section rod tube of layer overlaps outward, section rod tube comprises body, the key bar is set on the body surface, one end of body is provided with actuating sleeve, the other end is provided with positioning sleeve, and the rib circle is set between described positioning sleeve and the body, and the rib circle of internal layer section rod tube matches with the actuating sleeve of adjacent outer section rod tube.
The utility model is rational in infrastructure, and key strip adoption monolithic tooth-shape structure has overcome defectives such as the original structure weld seam is many, yielding, mechanical strength is low, has improved the mechanical strength of product.Being provided with in the positioning sleeve lower end of other each pole except that drilling rod first pole can movable rib circle, in the process of construction, avoided directly rubbing between actuating sleeve and the positioning sleeve like this, prolong the application life of actuating sleeve and positioning sleeve, solved the problem that kelly and positioning sleeve come off.

Fig. 2 is the structural representation of section rod tube.
The specific embodiment
A kind of rotary drilling rig drilling rod, comprise the section rod tube that the interior bar that is provided with conventional structure homalocephalus 1, square toes 5 and shock ring 2, compression spring 4, interior bar are nested layer by layer outward, section rod tube comprises body 3, key bar 9 is set on the body surface, one end of body 3 is provided with actuating sleeve 6, the other end of body 3 is provided with positioning sleeve 7, between positioning sleeve 7 and the body 3 rib circle 8 is set, and the rib circle 8 of internal layer section rod tube matches with the actuating sleeve 6 of adjacent outer section rod tube.
Claims (1)
