Detailed Description
As shown in fig. 1 and 2: an argon filling sealing device for stainless steel pipeline welding comprises an argon filling device, a sealing device, two moving devices and a monitoring device. The sealing system device plays a role in sealing when the stainless steel pipeline is filled with argon and can open or close the sealing system according to requirements. The two moving means may enable the sealing means to move within the stainless steel tubing. The monitoring system mainly comprises a camera and a data line, and realizes the transmission of data in the stainless steel pipeline. Whether the sealing system is completely opened or closed in the stainless steel pipeline is mainly monitored, and technicians outside the pipeline can conveniently determine whether the device can be filled with argon or moved out of the pipeline. The argon filling system consists of a hose for filling argon and an external argon bottle or an argon vehicle, and is used for filling the sealing device in the stainless steel pipeline with argon.
As shown in fig. 3: the sealing system mainly comprises a left circular truncated cone-shaped sealing plate, a right circular truncated cone-shaped sealing plate, an umbrella opening and closing device, a sliding block, a spring and a circular shaft.
The upper and lower sectors of the two circular truncated cone-shaped sealing plates can be opened or closed, which mainly plays a role of sealing argon gas and connects the left and right sealing plates through a circular shaft. The opening or closing of the sealing plate may be controlled by a remote control system.
The umbrella opening and closing device is connected with the upper sector and the lower sector of the sealing plate, the left sector and the right sector are respectively provided, when the device extends towards the two ends, the sealing plate is opened, and the moving process of the sealing device is matched; when the device compresses towards the middle, the sealing plate is closed, so that the argon filling of the sealing system can be realized, and the device is matched with the argon filling process for use.
The rectangular sliding blocks are respectively arranged on the left and the right, the middle of each rectangular sliding block is provided with a hole, and a circular shaft passes through the holes and can move left and right along the direction of the circular shaft. The left sliding block controls the left sealing plate, and when the sliding block moves leftwards, the opening angles of the upper sector and the lower sector of the left sealing plate are continuously increased until the sealing plate is completely opened; when the sliding block moves rightwards, the opening angles of the upper sector and the lower sector of the left sealing plate are continuously reduced until the sealing plate is completely closed. The right sliding block controls the right sealing plate, and when the sliding block moves to the right and left, the opening angles of the upper sector and the lower sector of the right sealing plate are continuously increased until the upper sector and the lower sector of the right sealing plate are completely opened; when the sliding block moves leftwards, the opening angles of the upper sector and the lower sector of the sealing plate on the right side are continuously reduced until the sealing plate is completely closed.
A spring is installed on the round shaft, and two ends of the spring are hinged with the sliding block. Through the spring action, can realize the transmission of two left and right slider forces, and the power that the slider transmission was come has realized opening and closing of umbrella opening and closing umbrella device, and then realizes opening and closing of closing plate.
As shown in fig. 4: the moving device consists of a positioning circular ring, four supporting springs and four moving blocks, wherein the positioning circular ring is sleeved outside a circular shaft of the sealing device, the four supporting springs are uniformly arranged on the positioning circular ring in the circumferential direction, and the four moving blocks are respectively arranged at the bottom ends of the four supporting springs.
The plastic positioning circular ring is sleeved outside the circular shaft of the sealing device, so that the moving device can move left and right along the direction of the circular shaft, and the positioning circular ring mainly plays a role in positioning. The distance between the moving block and the positioning circular ring can be adjusted through the four supporting springs through the springs, and the moving block is always in contact with the inner wall of the stainless steel pipeline to be filled with argon. The four moving blocks made of plastic materials are arranged at the bottom end of the supporting spring, so that the inner wall of the stainless steel pipeline can be prevented from being directly contacted with the supporting spring to scratch the inner wall of the pipeline.
As shown in fig. 5: when in use, the device is firstly inserted into a stainless steel pipeline 1 to be filled with argon, and the proper position of the argon filling device is adjusted by the moving device.
As shown in fig. 6: another stainless steel pipe 2 to be treated with argon is then inserted outside the apparatus of the invention and the monitoring device 3 observes whether the position of the sealing device 1 is proper and, if not, adjusts the moving device 2 to move it to the proper position.
As shown in fig. 7: when information fed back by the monitoring device 3 shows that the device moves to a proper position, the remote control sealing device 1 completely opens the left sealing plate 1 and the right sealing plate 1.1 to form an argon filling chamber between the two completely opened sealing plates, then argon is conveyed into the argon filling chamber through the argon filling device 4, when the content of the argon reaches a certain degree, the welding of the welding opening 7 is started, and the argon is continuously conveyed until the concentration of the argon meets the requirement. After welding, the sealing device 1 is remotely controlled, the left sealing plate 1 and the right sealing plate 1.1 are completely closed, and then the argon filling device is moved to the other end of the stainless steel pipeline through the moving device 2 to prepare for argon filling construction of a next pipeline section or move the next pipeline section out.
