The invention adopts the electromagnet 11 as a power source to push the circular ring 10 to carry out displacement operation. During the movement of the ring 10, the gas inlet means automatically introduce gas into the first cavity 9, the direction of the inlet being set at the distal end of the ring 10 with respect to the connecting rod 17. When the circular ring 10 moves, the gas in the first cavity 9 is promoted to flow into the connecting rod 17, the gas further pushes the sliding rod 6 to move, the accurate clamping connection between the clamping groove 7 and the cylinder 8 is realized, the pair of limiting pipes 3 is ensured to realize stable connection, and the synchronous rotation function of the clamping groove and the cylinder is realized.

The novel design realizes automatic connection and separation of the limiting pipe 3, and greatly improves the operation efficiency and accuracy.
The inner wall of the limiting pipe 3 is fixedly connected with a hollow elastic ring 12, and a group of connecting grooves 26 communicated with the inner wall of the first cavity 9 and the outer side wall of the elastic ring 12 are formed; in view of the fact that both the limiting pipe 3 and the pressure steel pipe are of circular design, when the limiting pipe 3 rotates, there may be a case that the limiting pipe 3 alone rotates and the pressure steel pipe cannot synchronously rotate. In order to solve the problem, when the pressure steel pipe is arranged in the limiting pipe 3, the elastic ring 12 is adopted to perform preliminary extrusion.

In the process, the gas in the first cavity 9 firstly flows into the connecting rod 17, and then pushes the sliding rod 6 to move. After the slide bar 6 and the cylinder 8 are clamped through the clamping groove 7, the movement of the slide bar is limited.

The air outlet end of the air outlet hole 15 is obliquely arranged, the air inlet end is horizontally arranged, and a sealing plate 16 is twisted at the bending part of the air outlet hole 15 through a torsion spring; during the process of gas entering the first cavity 9 through the mechanism and then flowing into the second cavity 13 through the connecting pipe 14, the air pressure in the second cavity 13 is gradually increased, and when the air pressure is increased to a preset threshold level, all sealing plates 16 are pushed away synchronously, so that the gas released from the air outlet holes 15 is pressurized and uniformly distributed, and the pressurized and uniformly distributed gas flow obviously improves the blowing effect on impurities on the surface of the penstock.

The design not only improves the safety of welding operation, but also obviously improves the working environment.
The inner wall of the protection ring 18, which is close to the welding port 19, is fixedly connected with a fixed plate 22, one side of the fixed plate 22, which is close to the welding port 19, is fixedly connected with a pressure sensor 23, one side of the limiting pipe 3, which is close to the sliding rod 6, is fixedly connected with a pressing plate 24, and the pressure sensor 23 is used for controlling the electromagnet 11 to be closed; in the present invention, when the limiting tube 3 rotates, the pressing plate 24 is driven to rotate synchronously, and once the pressing plate 24 presses the pressure sensor 23, the action indicates that the sliding rod 6 has reached the welding port 19, and at this time, the pressure sensor 23 receives a pressure signal to control the electromagnet 11 to close its working state. Subsequently, the slide bar 6 will move smoothly to the connecting bar 17, providing conditions for the welding robot 25 to perform the final welding task.
Embodiment two: as shown in fig. 8, in comparative example one, another embodiment of the present invention is: the inner wall of the elastic ring 12 is fixedly connected with a hollow elastic arc-shaped block 27, and air outlet grooves are formed in two sides of the arc-shaped block 27; when the elastic ring 12 is expanded, the inner wall of the elastic ring is correspondingly expanded, and in the process, the arc-shaped block 27 is subjected to double extrusion from the elastic ring 12 and the pressure steel pipe, so that the effect is that the gas in the arc-shaped block 27 is directionally pushed to the horizontal direction and directly blown to the pressure steel pipe from the gas outlet groove, the comprehensive blowing of impurities on the surface of the pressure steel pipe is realized, and the blowing cleaning effect of the pressure steel pipe is obviously improved by the design.

s4: the electromagnet 11 is started to push the circular ring 10 to move, at the moment, the circular ring 10 can push the gas in the first cavity 9 to enter the connecting rod 17, and then the gas can push the sliding rod 6 to enable the clamping groove 7 to be clamped with the cylinder 8;
S5: after the clamping groove 7 is clamped with the cylinder 8, the electromagnet 11 is controlled to be in an open state continuously, and then the annular ring 10 can continuously push the gas in the first cavity 9, so that the gas enters the elastic ring 12 from the connecting groove 26, the elastic ring 12 expands, and the pressure steel pipe is clamped and fixed;
s6: when the electromagnet 11 is closed, the ring 10 is reset under the pulling of the first spring, and at the moment, the ring 10 pushes the gas in the first cavity 9 to enter the second cavity 13 from the connecting pipe 14, and finally the gas is blown onto the penstock from the gas outlet hole 15.
Welding parameters and paths can be precisely controlled by the automated welding robot 25, and human operation errors are reduced, thereby improving welding quality and consistency.
Working principle: according to the invention, through the accurate operation flow, high-efficiency welding of the pressure steel pipes is realized, firstly, a pair of pressure steel pipes are accurately inserted into the limit pipes 3, under the bearing of the limit pipes 3, the accurate alignment of the ports, which are close to each other, of the pressure steel pipes is ensured, then, the movement of the slide rod 6 is accurately controlled by the driving mechanism, so that the clamping groove 7 on the slide rod 6 is firmly clamped with the cylinder 8, then, the automatic welding operation is carried out on the pressure steel pipes through the welding robot 25, in the welding process, the motor is started to drive the first gear 4 to rotate, the second gear 5 is driven to synchronously rotate, the rotation of the limit pipes 3 is further realized, the clamping groove 7 and the cylinder 8 are stably clamped, the pair of limit pipes 3 can simultaneously rotate, and the limit pipes 3 drive the pressure steel pipes therein to synchronously rotate, so that the full-range welding is realized, the convenience and the efficiency of the welding are greatly improved, when the slide rod 6 is about to move to the welding position, the driving mechanism accurately controls the inside of the connecting rod 6, any interference to the welding process of the pressure steel pipes is avoided, the whole operation flow is precise, the stability and the optimal income of welding quality and efficiency are ensured; the electromagnet 11 is used as a power source to push the circular ring 10 to carry out displacement operation. During the movement of the ring 10, the gas inlet means automatically introduce gas into the first cavity 9, the direction of the inlet being set at the distal end of the ring 10 with respect to the connecting rod 17. When the circular ring 10 moves, the gas in the first cavity 9 is promoted to flow into the connecting rod 17, the gas further pushes the sliding rod 6 to move, the accurate clamping connection between the clamping groove 7 and the cylinder 8 is realized, the pair of limiting pipes 3 is ensured to realize stable connection, and the synchronous rotation function of the clamping groove and the cylinder is realized. When the slide bar 6 is about to move to the welding position, the electromagnet 11 is turned off, and at the moment, the second spring acts to pull the slide bar 6 to retract into the connecting rod 17, so that the welding operation of the pressure steel pipe is prevented from being interfered. The novel design realizes the automatic connection and separation of the limiting pipe 3, and greatly improves the operation efficiency and accuracy;
In view of the fact that both the limiting pipe 3 and the pressure steel pipe are of circular design, when the limiting pipe 3 rotates, there may be a case that the limiting pipe 3 alone rotates and the pressure steel pipe cannot synchronously rotate. In order to solve the problem, when the pressure steel pipe is arranged in the limiting pipe 3, the elastic ring 12 is adopted to perform preliminary extrusion. Subsequently, the ring 10 is pushed by the power of the electromagnet 11. In the process, the gas in the first cavity 9 firstly flows into the connecting rod 17, and then pushes the sliding rod 6 to move. After the slide bar 6 and the cylinder 8 are clamped through the clamping groove 7, the movement of the slide bar is limited. At this time, the gas will flow into the connecting groove 26 and further fill the inside of the elastic ring 12 to expand it, thereby significantly enhancing the clamping effect on the penstock. Through the design, when the limiting pipe 3 rotates, the synchronous rotation of the pressure steel pipe can be driven more effectively, and the phenomenon that the welding quality of the pressure steel pipe is influenced due to the fact that the pressure steel pipe cannot rotate is avoided; when the ring 10 moves to one side of the connecting rod 17, external gas enters the second cavity 13 from the gas outlet hole 15 and then enters the first cavity 9 from the connecting pipe 14, when the electromagnet 11 is closed, the ring 10 is pulled by the first spring to reset, at the moment, the gas in the first cavity 9 is pushed to enter the second cavity 13 from the connecting pipe 14, and finally is blown onto the pressure steel pipe from the gas outlet hole 15, and before the pressure steel pipe is welded, the ring 10 is controlled to move by the electromagnet 11, so that the gas is blown onto the pressure steel pipe from the gas outlet hole 15, thereby the impurity at the welding position of the pressure steel pipe is blown away, the welding effect of the pressure steel pipe is improved, and the effect of rapidly cooling the welding position can be achieved by intermittently starting the electromagnet 11, so that the gas is continuously blown onto the welding position of the pressure steel pipe from the gas outlet hole 15;
In the process that the gas enters the first cavity 9 through the mechanism and then flows into the second cavity 13 through the connecting pipe 14, the air pressure in the second cavity 13 is gradually increased, when the air pressure is increased to a preset threshold level, all sealing plates 16 are pushed away synchronously, so that the gas released from the gas outlet holes 15 is pressurized and uniformly distributed, and the pressurized and uniformly distributed gas flow can obviously improve the blowing effect on impurities on the surface of the pressure steel pipe; in the welding process for the penstock, the invention particularly designs a safety protection mechanism, in particular, a welding head of the welding robot 25 can accurately extend into the welding port 19 to perform welding operation, in the process, in order to ensure working safety and prevent possible injury to workers caused by spark splashing, a protection ring 18 is particularly provided, which can effectively block sputtering of sparks, and in order to keep the working environment clean, the protection ring 18 can effectively intercept impurities generated in the welding process, and the impurities can slide into the mounting pipe 20 along a specific path and are finally collected intensively by the collecting box 21. The design not only improves the safety of welding operation, but also obviously improves the working environment; in the present invention, when the limiting tube 3 rotates, the pressing plate 24 is driven to rotate synchronously, and once the pressing plate 24 presses the pressure sensor 23, the action indicates that the sliding rod 6 has reached the welding port 19, and at this time, the pressure sensor 23 receives a pressure signal to control the electromagnet 11 to close its working state. Subsequently, the slide bar 6 will move smoothly to the connecting bar 17, providing conditions for the welding robot 25 to perform the final welding task.
