When connecting the socket of the steel pipe and the spigot of the steel pipe, it is convenient for the installation and positioning of the semi-circular ring, and it is convenient to disassemble after the steel pipe is installed, which is convenient for repeated use and improves the convenience and practicability. The specific content is as follows:

[0020] 1. A connecting component is arranged outside the socket of the steel pipe and the spigot of the steel pipe. When connecting and sealing the socket of the steel pipe and the spigot of the steel pipe, two semi-circular rings are sleeved on one side of the positioning ring on the socket of the steel pipe, and then the fixing blocks and the connecting blocks on the two semi-circular rings are fitted together, so that the positioning blocks are inserted into the connecting grooves. Bevels are arranged on the lower side of one side of the positioning block and the top of the J-shaped rod, so that when the positioning block is inserted, it can push the J-shaped rod to move, so that the telescopic spring can be stretched. After the fixing block and the connecting block are fitted together, the J-shaped rod can be aligned with the positioning groove on the positioning block, and the telescopic spring can recover its deformation, so that the J-shaped rod can be engaged with the positioning groove, so as to position the fixing block, and then position the two semi-circular rings. The movable block is driven to move by the electric push rod, and the movement of the movable block drives the guide rod to move for limiting, and then the connecting ring can be pulled to move through the connecting rope, so that the spigot of the steel pipe is inserted into the socket of the steel pipe and the sealing ring is extruded for sealing. Then, the mounting ring and the connecting ring are fixed by bolts to complete the fixing of the spigot and the socket of the steel pipe. Then, the push block can be pushed to drive the J-shaped rod to move, and the movement of the J-shaped rod drives the sliding block to slide in the sliding groove for support. After the J-shaped rod moves, it disengages from the positioning groove, so that the positioning block loses its limit, and then the two semi-circular rings can be removed. By using the connecting component to connect the socket of the steel pipe and the spigot of the steel pipe, it is convenient for the installation and positioning of the semi-circular ring, and it is convenient to disassemble after the steel pipe is installed, which is convenient for repeated use and improves the convenience and practicability;

[0021] 2. When connecting the socket of the steel pipe and the spigot of the steel pipe, after the semi-circular ring is fixed, the connecting sleeve is inserted into the support ring. Since one side of the two limit blocks is inclined, the sliding limit block that moves when the connecting sleeve is inserted into the support ring contacts the support ring, so that the two limit blocks and the movable plate approach each other, so that the movable plate slides on the fixed rod and compresses the return spring. After the limit block passes through the support ring, it is reset under the action of the return spring, so that the connecting sleeve can be fixed on the support ring. The support ring can be pulled to move through the connecting rope and the connecting sleeve, so that the connecting ring and the spigot of the steel pipe can be driven to move. After the steel pipe is installed, the handle can be pulled to drive the movable rod to move. After the movable rod moves, the connecting rod can be pulled to rotate. After the connecting rod rotates, the two movable plates can be pulled to approach each other, so that the limit block no longer fits the support ring, so that the connecting sleeve can be removed, which facilitates the fixing of the connecting sleeve and is convenient for removing the connecting sleeve after the steel pipe is installed, improving the practicability.

[0031] Working principle: Before using this sealing device for large-diameter socket steel pipes, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 5As shown in the figure, a connection component 2 is provided outside the steel pipe socket 101 and the steel pipe spigot 1. When connecting and sealing the steel pipe socket 101 and the steel pipe spigot 1, two semi-circular rings 201 are sleeved on one side of the positioning ring 105 on the steel pipe socket 101. Then, the fixing blocks 206 and the connecting blocks 207 on the two semi-circular rings 201 are fitted together, so that the positioning block 209 is inserted into the inside of the connecting groove 208. An inclined surface is provided on the lower side of one side of the positioning block 209 and the top of the J-shaped rod 210, so that the insertion of the positioning block 209 can push the J-shaped rod 210 to move, so that the telescopic spring 211 can be stretched. After the fixing block 206 and the connecting block 207 are fitted together, the J-shaped rod 210 can be aligned with the positioning groove 213 on the positioning block 209, and the telescopic spring 211 can restore its deformation, so that the J-shaped rod 210 can be engaged with the positioning groove 213, so as to position the fixing block 206, and further position the two semi-circular rings 201. The movable block 203 is driven to move by the electric push rod 202, and the movement of the movable block 203 drives the guide rod 204 to move for limiting. Then, the connecting ring 103 can be pulled to move through the connecting rope 205, so that the steel pipe spigot 1 is inserted into the steel pipe socket 101 and the sealing ring 104 is extruded for sealing. Then, the mounting ring 102 and the connecting ring 103 are fixed by bolts to complete the fixing of the steel pipe spigot 1 and the steel pipe socket 101. Then, the push block 212 can be pushed to drive the J-shaped rod 210 to move, and the movement of the J-shaped rod 210 drives the sliding block 215 to slide inside the sliding groove 214 for support. After the J-shaped rod 210 moves, it disengages from the positioning groove 213, so that the positioning block 209 loses its limit, and then the two semi-circular rings 201 can be removed. The connection component 2 is used to connect the steel pipe socket 101 and the steel pipe spigot 1, which is convenient for the installation and positioning of the semi-circular rings 201. And after the steel pipe is installed, it is convenient to disassemble, which is convenient for repeated use and improves the convenience and practicality;

[0032] When connecting the socket end 101 of the steel pipe to the spigot end 1 of the steel pipe, after the semi-circular ring 201 is fixed, the connecting sleeve 217 is inserted into the support ring 216. Since one side of the two limit blocks 220 is inclined, the sliding limit block 220 that moves when the connecting sleeve 217 is inserted into the support ring 216 contacts the support ring 216, causing the two limit blocks 220 to approach the movable plate 219, making the movable plate 219 slide on the fixed rod 218 and compress the return spring 221. After the limit block 220 passes through the support ring 216, it is reset under the action of the return spring 221, enabling the connecting sleeve 217 to be fixed on the support ring 216. By means of the connecting rope 205 and the connecting sleeve 217, the support ring 216 can be pulled to move, so that the connecting ring 103 and the spigot end 1 of the steel pipe can be driven to move. After the steel pipe is installed, the handle 223 can be pulled to drive the movable rod 222 to move. After the movable rod 222 moves, the connecting rod 224 can be pulled to rotate. After the connecting rod 224 rotates, the two movable plates 219 can be pulled to approach each other, causing the limit blocks 220 to no longer fit the support ring 216, so that the connecting sleeve 217 can be removed. This facilitates the fixation of the connecting sleeve 217 and is convenient for removing the connecting sleeve 217 after the steel pipe is installed, improving the practicality.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
