Abstract
The utility model discloses a drill rod for a rock drilling jumbo, relates to the technical field of drill rods, and solves the technical problem that the drill rod is often fixed infirm. The utility model has the advantages of quick installation, falling prevention, more firmness and convenient dust removal.
Description
Technical Field
The utility model belongs to the technical field of drill rods, and particularly relates to the technical field of rock drilling jumbo.
Background
The rock drilling jumbo is a rock drilling device for tunnel and underground engineering by adopting drilling and blasting method, and can be moved and can be used for drilling hole.
The drill rods used on the rock drilling jumbo are abraded quickly, some spare drill rods are required to be prepared on site generally, the drill rods are often not fixed firmly due to complex rock drilling site conditions, and particularly the drill rods are easy to fall off and loosen by adopting a fixing device for fixing the drill rods in a clamping mode, so that potential safety hazards are brought.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art, and provides a drill rod for a rock drilling jumbo.
The technical scheme adopted by the utility model is as follows:
the drill rod for the rock drilling trolley comprises a drill rod body, wherein installation steps are symmetrically arranged at two ends of the drill rod body, and positioning holes are formed in the installation steps.
Preferably, the installation step is provided with raised grains.
Preferably, the inner wall of the positioning hole is provided with threads, a positioning column is connected in the positioning hole through the threads, the outer wall of the positioning column is provided with threads, and a groove is formed in the top end face of the positioning column.
Preferably, the shape of the groove includes at least one of a cross shape, a regular hexagon shape, and a straight shape.
In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that:
1. the installation step makes things convenient for fixing device to fix a position quick installation to the drilling rod, and avoids the drilling rod to remove to drop on its length direction.
2. The drill rod is fixed more tightly by arranging the raised grains to increase the friction force when the fixing device is contacted with the installation step.
3. The design effect of recess is for making things convenient for the staff use instrument to take out the reference column from the locating hole through the recess and handle the dust.

Reference numerals: 1-a drill rod body, 2-an installation step, 3-a raised grain, 4-a groove, 5-a positioning column and 6-a positioning hole.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the case of the example 1, the following examples are given,
referring to fig. 1-2, the drill rod for the rock drilling jumbo comprises a drill rod body 1 and installation steps 2 symmetrically arranged at two ends of the drill rod body 1, wherein positioning holes 6 are formed in the installation steps 2. The installation step 2 facilitates the fixing device to position and install the drill rod quickly, and prevents the drill rod from moving and falling off in the length direction. The positioning hole 6 is connected with a positioning screw on the fixing device in a matching way and is used for fixing the drill rod to prevent the drill rod from falling out of the fixing device.
Wherein, be equipped with raised grain 3 on the installation step 2. The drill rod is held tighter by providing the corrugations 3 to increase the friction when the fixture is in contact with the mounting step 2.
The inner wall of the positioning hole 6 is provided with threads, the positioning hole 6 is internally connected with a positioning column 5 through the threads, the outer wall of the positioning column 5 is provided with threads, and a groove 4 is formed in the top end face of the positioning column 5. Recess 4's design effect is for making things convenient for staff's use of tools to take out reference column 5 from locating hole 6 through recess 4, in addition because the dust is easily piled up to locating hole 6 inside, consequently through taking out reference column 5 in order to reach the accumulational dust in the washing locating hole 6 from locating hole 6.
Wherein, the shape of the groove 4 comprises at least one of a cross shape, a regular hexagon shape and a straight line shape.
When the drill rod fixing device is used, the fixing block on the fixing device is correspondingly clamped on the mounting step 2, and the positioning screw on the fixing block is matched and connected with the positioning hole 6 to fix the drill rod.
When the dust in the locating hole 6 needs to be cleared up, the staff screws out the locating column 5 through the tool to clear up the dust on the locating column 5.
