AI Technical Summary
During the tapping process, the drill rod of a traditional tapping machine becomes screwed shut with the connecting sleeve of the tapping machine due to the continuous tightening of the screw threads. This makes it difficult to detach in a timely, efficient, and low-intensity manner, affecting the smoothness of drilling and tapping, and increasing the workload of furnace operators.
The system employs a sleeve, drill pipe body, and washer structure. The washer is made of rubber and is located at the first threaded end of the drill pipe body. The stop ring is welded and fixed to the drill pipe body, which prevents over-tightening through a limiting action and allows for rapid disengagement via a reverse opening machine.
It effectively prevents the drill rod from being overtightened with the opening machine sleeve, reduces workload, ensures smooth drilling and iron output, reduces spare parts consumption, and improves sealing and reliability.

TECHNICAL FIELD
[0001] The utility model relates to the technical field of open machine drill rod for metallurgical blast furnace, and particularly relates to a quick-release drill rod device of open machine. BACKGROUND
[0002] In blast furnace smelting, the open machine is a very important front furnace equipment, which undertakes the task of opening the iron hole and smoothly tapping. The drill rod connection mode of the open machine used in the metallurgical industry at present is mostly two-end thread connection, one end is connected with the open machine connecting sleeve, and the other end is connected with the drill bit. The two-end thread connection mode determines that the drill rod can only be in the normal rotation state during the iron hole opening process. It is found in the use process that the drill rod of this form will appear difficult to separate from the open machine connecting sleeve during replacement, which on the one hand increases the working strength of the front furnace worker, and on the other hand affects the timely drilling and smooth tapping at the front furnace, and causes the waste of spare parts. Through on-site analysis, the main reason for the difficulty in separating the drill rod is that the open machine is always in normal rotation during the iron hole opening process, which continuously tightens the screw thread, and finally causes the screwing of the drill rod and the open machine connecting sleeve. Therefore, a drill rod device capable of timely and rapid separation after the open machine finishes opening the iron hole needs to be developed. SUMMARY
[0003] The utility model aims at the above problems, provides a kind of quick-release drill rod device of open machine, solves the technical problem that the conventional weapon machine drill rod is always in normal rotation during the iron hole opening process, which continuously tightens the screw thread, and finally causes the screwing of the drill rod and the open machine connecting sleeve, is not convenient for timely, efficient, low-intensity separation drill rod.
[0004] To achieve the above object, the technical scheme adopted by the utility model is as follows:
[0005] A kind of quick-release drill rod device of open machine, including sleeve, drill rod body and spacer ring, the sleeve is provided with coaxial through hole, the first threaded end of the drill rod body one end is provided with and stop ring, the other end is provided with second threaded end, the first threaded end is screwed in the hole;The spacer ring is sleeved on the first threaded end, one end of the spacer ring is abutted with one end of the sleeve, and the other end is abutted with one end of the stop ring.
[0006] Further, the drill rod body is provided with a through hole penetrating coaxially.
[0007] Further, the spacer ring is made of rubber material.
[0008] Further, the stop ring and the drill rod body are processed separately, and the stop ring is welded and fixed after being sleeved on the drill rod body.
[0009] Further, a plurality of welding holes are arranged on the stop ring, and the welding holes are communicated with the center hole of the stop ring.
[0010] Further, the stop ring is welded and fixed away from one end of the grommet ring to the drill rod body, and the welding hole is filled with welding and welded and fixed to the drill rod body.
[0011] With the technical scheme, the utility model has the advantages that:
[0012] 1. In the process of the drill rod body rotating forward, the grommet ring plays a limiting role, which can effectively prevent the drill rod body from being excessively screwed with the sleeve of the opening machine during the operation of the opening machine, so that the drill rod cannot be replaced, and the drill rod can be easily separated from the opening machine by starting the impact and reversing the opening machine, thereby greatly reducing the working intensity in front of the furnace. At the same time, the drilling and tapping are smooth, the consumption of spare parts is reduced, and the stable operation of the blast furnace is of great significance. The technical problem that the conventional weapon machine drill rod is always in forward rotation during the tapping process, the screw is continuously screwed, and the drill rod is finally screwed with the connecting sleeve of the opening machine, which is not convenient for timely, efficient and low-intensity separation of the drill rod.
[0013] 2. The grommet ring is placed at the first threaded end of the drill rod body, which can prevent the thread from failing and prolong the service life, and the grommet ring is expanded to form a seal to prevent water from leaking from the stop connection position and affecting the tapping problem, thereby improving the sealing performance. After the water vapor mixture passes through the sleeve screw hole and the drill bit body through hole, it reaches the drill bit working position, and the blowing effect of the cooling drill rod body and the drill bit is better, thereby ensuring the safe and smooth development of the tapping work.
[0014] 3. The stop ring and the drill rod body are provided, so that the stop ring can be effectively and quickly separated by only adding the stop ring to the ordinary drill rod, which is simple and fast. The end of the stop ring and the welding hole are welded in multiple points, so that the connection strength of the stop ring and the drill rod body is high, and the reliability is improved.
