[0029] Please refer to Figures 1 to 5 , the present invention provides a technical solution:

[0030] A high-temperature resistant hot piercing plug includes a column 1, a replacement component 2 is arranged at the top of the column 1, a reinforcement component 3 is arranged on one side of the column 1, and a mounting component 4 is arranged at the bottom of the column 1;

[0031] The replacement component 2 includes a slot 201, a plug 202, a tip 203, a sliding slot 204, a fixing plate 205 and a fixing groove 206. The slot 201 is opened at the top of the column 1, the plug 202 is arranged inside the slot 201, the tip 203 is fixedly connected to the top of the plug 202, the sliding slot 204 is opened on one side of the plug 202, a plurality of fixing plates 205 are fixedly connected inside the slot 201 and slidably connected inside the sliding slot 204, and a plurality of fixing grooves 206 are opened on one side of the sliding slot 204 and are used in cooperation with the fixing plates 205 for sliding connection.

[0032] Specifically, as Figure 5 shown, the reinforcement component 3 includes a reinforcement groove 301, a reinforcement ring 302 and a reinforcement threaded ring 303. The reinforcement groove 301 is opened on one side of the column 1, the reinforcement ring 302 is fixedly connected to the bottom of the tip 203 and is used in cooperation with the reinforcement groove 301 for insertion, and the reinforcement threaded ring 303 is threadedly connected between the reinforcement groove 301 and the reinforcement ring 302.

[0033] When in use, when the tip 203 needs to be replaced, the plug 202 of the tip 203 is inserted into the slot 201 inside the column 1, so that the fixing plate 205 slides inside the sliding slot 204. After the plug 202 penetrates into the slot 201, the tip 203 is rotated, driving the plug 202 to rotate inside the slot 201, driving the fixing plate 205 to enter the fixing groove 206 along the sliding slot 204 and clamping the fixing groove 206. At this time, the reinforcement ring 302 will also be inserted into the reinforcement groove 301, and then the reinforcement threaded ring 303 is rotated, driving the reinforcement threaded ring 303 to move on the side wall of the reinforcement groove 301. Finally, the reinforcement threaded ring 303 will be threadedly moved between the reinforcement groove 301 and the reinforcement ring 302 to limit and fix the reinforcement ring 302, completing the replacement of the tip 203, making it convenient to directly replace the tip 203, and enabling different tips 203 to be replaced to adapt to the drilling operations in different environments.

[0034] Specifically, as Figure 4 shown, the mounting component 4 includes a mounting block 401 and a mounting groove 402. The mounting block 401 is fixedly connected to the bottom of the column 1, and the mounting groove 402 is formed on one side of the mounting block 401.

[0035] Specifically, as Figure 4 shown, a heat dissipation groove 5 is formed between the column 1 and the tip 203. The number of the heat dissipation grooves 5 is multiple and they are evenly distributed between the column 1 and the tip 203.

[0036] Specifically, as Figure 4 shown, a plurality of communication grooves 6 are formed inside the mounting block 401. The communication grooves 6 are used to cooperate with the heat dissipation groove 5 and conduct the heat inside the heat dissipation groove 5.

The heat dissipation groove 5 can collect the heat generated by the tip 203 during working drilling, and then discharge it through the communication groove 6, improving the heat dissipation efficiency and service life of the tip 203. The threaded grooves 7 and the reinforcing block 8 can increase the drilling efficiency of the tip 203, and the plasma cladding coating can enhance the high-temperature resistance of the column 1 and the tip 203.

[0041] By adopting the above technical solutions, the problems that it is inconvenient to directly replace the tip 203 during the actual use of the existing high-temperature resistant hot piercing plug, resulting in waste of resources, and the low heat dissipation efficiency of the plug leading to a short service life of the plug are solved.

[0042] Working principle: When this application is in use, first, when the center point 203 needs to be replaced, insert the insertion rod 202 of the center point 203 into the inside of the slot 201, so that the fixing plate 205 slides inside the sliding groove 204. After the insertion rod 202 penetrates into the inside of the slot 201, rotate the center point 203, drive the insertion rod 202 to rotate inside the slot 201, drive the fixing plate 205 to enter the inside of the fixing groove 206 along the sliding groove 204 and latch the fixing groove 206. At this time, the reinforcement ring 302 will also be inserted into the inside of the reinforcement groove 301, and then rotate the reinforcement threaded ring 303, drive the reinforcement threaded ring 303 to move on the side wall of the reinforcement groove 301. Finally, the reinforcement threaded ring 303 will be threadedly moved between the reinforcement groove 301 and the reinforcement ring 302 to limit and fix the reinforcement ring 302, completing the replacement of the center point 203, making it convenient to directly replace the center point 203, and enabling different center points 203 to be replaced to adapt to drilling operations in different environments. The column 1 can be conveniently installed at a suitable working position through the mounting block 401 and the mounting groove 402. The heat dissipation groove 5 can collect the heat generated by the center point 203 during drilling operations, and then discharge it through the communication groove 6, improving the heat dissipation efficiency and service life of the center point 203. The threaded groove 7 and the strengthening block 8 can increase the drilling efficiency of the center point 203, and the plasma cladding coating can enhance the high-temperature resistance of the column 1 and the center point 203.
