[0002] A drill rod is a tool for connecting a drill bit and rock drilling in shaft and drift engineering. The drill rods generally used in mine shaft and drift engineering are hexagonal hollow steel and hollow round steel. The inscribed circle diameter of the hexagonal hollow steel is 22 mm and 25 mm, and the outer diameter of the hollow round steel is 32 mm and 38 mm. The drill rods include finished drill rods and forged drill rods. The finished drill rod is forged to a certain length and then directly installed with a drill bit for drilling. The forged drill rod is sheared from the hollow hexagonal steel according to needs, and then the drill rod tail and drill rod head are forged by a drill rod forging machine, and then installed with a drill bit for drilling.

[0003] After a large amount of retrieval, it is found that when the existing drill rod is processed, the tip needs to be heated. At present, the heating method is usually that after one tip is heated, the power is cut off and then the next tip is replaced, and then the power is turned on for heating. Although this method is feasible, the cyclic start-up requires a large amount of labor, and dust adheres to the surface of the tip and cannot be cleaned.

Detailed implementation mode

[0021] The present utility model will be further described below in conjunction with the accompanying drawings and the implementation mode.

[0022] First embodiment

[0023] Please refer to Figures 1-4 . A high-frequency induction heating device for the tip of a drill rod includes a device body 1, a ring-shaped heating tube 2 is installed inside the device body 1, a delivery pipe 6 is penetrated and arranged on the outer surface of the device body 1, an infrared emitter 12 is penetrated and arranged on the top surface of the delivery pipe 6, and an infrared receiver 10 is penetrated and arranged on the bottom surface of the delivery pipe 6 directly below the infrared emitter 12.

[0024] By setting the coordinated use of the delivery pipe 6, the infrared emitter 12, and the infrared receiver 10, it is convenient to perform induction heating on the tip of the drill rod. During operation, when the infrared emitter 12 is started, when the infrared receiver 10 receives the signal of the infrared emitter 12, it indicates that there is no drill rod being transported inside the delivery pipe 6. At this time, the controller 4 turns off the heating of the ring-shaped heating tube 2. When the infrared receiver does not receive the signal, it indicates that there is a drill rod being transported inside the delivery pipe 6. At this time, the signal is transmitted to the controller 4, and then the controller 4 starts the ring-shaped heating tube 2, so that the ring-shaped heating tube 2 can heat the tip inside. Then, by analogy, this method is simple to operate, does not require cyclic manual startup, and reduces the labor of the staff.

[0025] The working principle of a high-frequency induction heating device for the tip of a drill rod provided by the present utility model is as follows:

[0026] When operating this high-frequency induction heating device for the tip of the drill rod, start the infrared transmitter 12. When the infrared receiver 10 receives the signal from the infrared transmitter 12, it indicates that there is no drill rod being transported inside the conveying pipe 6. At this time, the controller 4 turns off the heating of the annular heating pipe 2. When the infrared receiver does not receive the signal, it means that there is a drill rod being transported inside the conveying pipe 6. At this time, the signal is transmitted to the controller 4, and then the controller 4 starts the annular heating pipe 2, so that the annular heating pipe 2 can heat the tip inside. Then, by analogy, this operation method is simple and does not require cyclic manual startup, reducing the labor of the staff. By setting the treatment cylinder 13 and the wire brush 15, after the tip of the drill rod enters the device body 1 through the conveying pipe 6, it first passes through the treatment cylinder 13. During the process of passing through the treatment cylinder 13, the internal wire brush 15 cleans the dust on the surface of the tip. After that, when the tip is heated and pulled out, it is further processed by the wire brush 15 to clean the ash and impurities burned on the surface. This method is simple in operation and convenient for subsequent processing of the tip.

When operating, start the infrared transmitter 12. When the infrared receiver 10 receives the signal from the infrared transmitter 12, it indicates that there is no drill rod being transported inside the conveying pipe 6. At this time, the controller 4 turns off the heating of the annular heating pipe 2. When the infrared receiver does not receive the signal, it means that there is a drill rod being transported inside the conveying pipe 6. At this time, the signal is transmitted to the controller 4, and then the controller 4 starts the annular heating pipe 2, so that the annular heating pipe 2 can heat the tip inside. Then, by analogy, this operation method is simple and does not require cyclic manual startup, reducing the labor of the staff. By setting the treatment cylinder 13 and the wire brush 15, after the tip of the drill rod enters the device body 1 through the conveying pipe 6, it first passes through the treatment cylinder 13. During the process of passing through the treatment cylinder 13, the internal wire brush 15 cleans the dust on the surface of the tip.
