Description

Drill pipe structure of drilling machine

The present invention relates to a partial structure of a drilling machine, in particular to an inventor of an innovative drill pipe structure type of a drilling machine.

In the design of the drilling rig structure, the function of drilling the ground hole is usually achieved by connecting the bottom end joint of the driving machine to a drill rod. The conventional drill rod is similar to the axial long extension. In the straight strip-shaped groove type, the spacer ring is arranged on the peripheral wall of the drill rod body, and the drill rod is driven by the driving seat to generate rotation and vibration, thereby achieving the purpose of drilling the ground hole.

However, the above-mentioned axial straight groove type drill pipe of the conventional drilling machine has found some problems in the actual use experience, for example, because the straight groove type drill pipe is in the process of drilling the ground hole, the soil material and the stone The granules will be discharged by the grooves of the straight groove type drill pipe. When the groove is worn for a long time, it is impossible to repair and the serious problem of eliminating the entire drill pipe; further, the peripheral wall of the straight groove type drill pipe has a large contact area. The greater the resistance, the greater the power consumption of the driver seat. Therefore, once these problems occur, the subsequent problems are quite troublesome, which will inevitably lead to problems such as delays in construction and increased construction costs. Relevant industry issues discussed in the relevant industry.

Therefore, in view of the problems existing in the axial straight groove type drill pipe structure of the above-mentioned conventional drilling machine, how to develop an innovative structure with more ideal practicability, which the user hopes, is also required by the relevant industry to develop The goal and direction of the breakthrough; in view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical and practical creation.

The main purpose of this creation is to provide a drill pipe structure for a drilling machine. The technical problem to be solved is to aim at how to develop a drill pipe structure type of a new type of drilling machine with more ideal and practicality. Innovate breakthroughs. The drill rod is used for the joint provided at the bottom end of the driving seat of a drilling machine.

Based on the foregoing objects, the technical feature of the present invention is mainly that the drill pipe comprises: a rod body, which is a pole type extending along an axial direction, the rod body has a driven end and a drill end. The driven end is configured to be connected to the joint of the drilling machine, and the drill end is provided with a drill bit; more than one rib is arranged on the peripheral wall of the rod body, and the rib is arranged It is a strip shape extending axially along the rod body.

With this innovative unique pattern and technical features, this creation can provide a ribbed drill pipe that is more suitable for drilling holes in soft and hard soils than the prior art, and the ribs will be worn during the drilling process. Even if it is broken, the ribs are repaired back by welding or male and female snaps, thereby achieving practical progress and better industrial utilization benefits when the soil discharging function and the rib damage are easily repaired.

Another purpose of the present invention is that the rib is provided on the peripheral wall of the rod body, and in the process of drilling the hole, the contact area of the rib is small, and the degree of resistance is small, and the power consumption of the driving seat is small. Practical and progressive.

Referring to Figures 1 through 4, there is shown a preferred embodiment of the drill pipe structure of the present boring machine, but such embodiments are for illustrative purposes only and are not limited by this structure in the patent application. The drill pipe A is used for mounting a joint 11 at the bottom end of a drive base 10 of a drilling machine.

The drill pipe A comprises the following structure: a rod body 20 is a pole type extending along an axial direction, the rod body 20 has a driven end 21 and a drill end 22, and the driven end 21 The joint 11 is assembled to the drive base 10 of the drilling machine, and the drill end 22 is provided with a drill bit 23; one or more ribs 30 are arranged on the peripheral wall of the rod body 20; The ribs 30 are in a strip shape extending axially along the rod body 20.

As shown in FIG. 4, in this example, the ribs 30 are cylindrical and rectangular, and the staggered spacers are disposed on the peripheral wall of the rod body 20.

With the above-mentioned structural composition and technical features, the actual operation of the drill pipe A structure of the drilling machine disclosed in the present invention is as follows: as shown in Fig. 5, the driven end 21 of the drill pipe A is connected. At the joint 11 of the drive base 10, the drill end 22 of the drill rod A is connected to the drill bit 23, and is driven to rotate through the drive base 10 and is displaced downward, and drives the drill rod A and the drill bit 23 to facilitate the drill bit. 23, a vertical hole is drilled in the ground, and the earth material generated during the drilling process of the drill pipe A is rotated downward, and the ribs 30 are provided through the peripheral wall of the rod body 20, and the ribs 30 are The gap between the ribs 30 is guided upward and moved out; the drill pipe A disclosed in the present invention is mainly provided with a rib shape of the rib 30 by the peripheral wall of the rod body 20, which is opposite to the conventional straight groove type drill pipe. In terms of the type, the rib 30 is assembled to the rod body 20 by welding or male and female snaps, which is achieved when the rib 30 is worn and damaged, and the repairing effect is greatly improved; In the middle, because the contact area of the rib 30 is small, the degree of resistance is relatively small, and the power consumption of the driving base 10 is small, and is more suitable for In the land of hard and soft drilled holes in the job.

As shown in Figures 6 and 7, in this example, the rib 30 is in the shape of a cylindrical shape or a rectangular column; the embodiment of the present embodiment mainly illustrates that the rib 30 is a rectangular cylinder (e.g. 6) and cylindrical (as shown in Fig. 7), the rectangular column is small in contact with the ground surface, and the degree of resistance is small when entering the ground construction, and the cylindrical system has no angular relationship. At the beginning of the construction on the ground, the drill pipe A is made easier to rotate on the ground.

As shown in Fig. 8, in this example, the outer surface of the rib 30 has a thread 31 (shown in a cylindrical shape); the embodiment of the present embodiment mainly describes the contact of the thread 31 when drilling the ground. The area is smaller and the relative resistance is also smaller, which makes the soil and stone particles stronger.

In addition, the rib 30 is arranged in the ring body 20 in the rod body 20  Any of the following combinations: welded type, male and female type; the rib 30 shown in Figures 1 to 7 is a welded type; and the rib 30 is shown in Fig. 9. The embodiment of the present invention is mainly a description of the embodiment of the male and female snaps; the embodiment of the present embodiment mainly illustrates that the welded type is blocked by the rib 30 on the rod body 20 by the welding rod, and the male and female buckle type are the tails of each other. When the ribs 30 and the rod body 20 are coupled to each other, the fixing ribs 40 are fixed, so that the ribs 30 are more stable and not easily displaced. When the ribs 30 are worn and damaged, they can be welded or male-female. To repair the damaged area of the rib 30.
