A device to prevent leak welding

Abstract

This utility model discloses an anti-leakage welding device, comprising: a base, a support frame for stabilizing the device fixedly connected to the top of the base, a connecting column fixedly connected to one side of the support frame, and a mounting frame fixedly connected to the end of the connecting column away from the support frame. A visualization mechanism is fixedly connected inside the mounting frame. This utility model controls an electric push rod to push a sliding ring forward, causing it to slide on the surface of the connecting column. This causes the drive bar to push the connecting bar outward until the airbag is close to the inside of the pipe. At this point, the weld seam is located inside the airbag. Simultaneously, a fan is activated, and airflow sequentially passes through the connecting pipe, through hole, bend, and telescopic pipe to inflate the airbag. After inflating, an electronic valve is opened, and the airflow contacts the inner wall of the pipe. The device then displays whether there are any changes inside the airbag, facilitating post-weld inspection of the weld seam, ensuring the seal of the weld, and preventing leaks that could affect subsequent pipe use.

Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a device for preventing weld leakage. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Modern welding utilizes various energy sources, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. Besides its use in factories, welding can be performed in a variety of environments, such as outdoors, underwater, and in space. Regardless of the location, welding can pose dangers to operators, so appropriate protective measures must be taken. Potential injuries from welding include burns, electric shock, vision impairment, inhalation of toxic fumes, and excessive ultraviolet radiation exposure.

[0003] Currently, pipeline welding relies on experience and visual observation to assess the welding process. Furthermore, it is impossible to observe the internal condition of the pipeline. If there are any missed welds or weld seams, it can easily affect the safety of the pipeline in the later use. Moreover, after welding, it is impossible to visually inspect the internal sealing of the weld. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing pipe welding methods, which make it impossible to observe the internal condition of the pipe during welding and to visually inspect the weld seal after welding.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a leak-proof welding device, comprising: a base, a support frame for stabilizing the device fixedly connected to the top of the base, a connecting column fixedly connected to one side of the support frame, and an mounting frame fixedly connected to the end of the connecting column away from the support frame;

[0006] The mounting bracket has a fixed internal visualization mechanism, and the connecting column has a movable external connection to a leak detection mechanism.

[0007] Furthermore, the leak detection mechanism includes a connecting strip, an air bladder, an electronic valve, a drive strip, and a telescopic tube. Several connecting strips are arranged in a circular array, and the drive strips are movably connected to the bottom end of the connecting strips via rotating shafts. The air bladder is fixedly connected to the outside of the connecting strip. Several electronic valves are installed inside the air bladder. The telescopic tube is fixedly connected to the bottom of the connecting strip, and the top end of the telescopic tube passes through the connecting strip and the air bladder and communicates with the inside of the air bladder.

[0008] Furthermore, the airbag is annular and has a concave cross-section, the connecting strip is arc-shaped, a sliding ring is slidably connected to the surface of the connecting post, and the end of the drive strip away from the connecting strip is movably connected to the surface of the sliding ring via a rotating shaft.

[0009] Furthermore, an electric push rod is fixedly connected to the side of the support frame near the connecting column, and the output end of the electric push rod is fixedly connected to the outside of the sliding ring.

[0010] Furthermore, the connecting column has a through hole opened laterally inside, and a bent pipe is fixedly connected to one end of the through hole, and the other end of the bent pipe is fixedly connected to the bottom end of the telescopic pipe. A fan is fixedly connected to the surface of the base, and a connecting rod is fixedly connected to one end of the fan. One end of the connecting pipe passes through the connecting column and communicates with the through hole.

[0011] Furthermore, the visualization mechanism includes a servo motor, a drive disk, a fixing bar, and a camera. The drive disk is fixedly connected to the output end of the servo motor via a coupling. The fixing bars are symmetrically arranged and fixedly connected to the outside of the drive disk. The cameras are fixedly connected to one end of each fixing bar.

[0012] Furthermore, the servo motor is fixedly connected inside the mounting bracket, and the fixing strips are all located on the outside of the fixing strips.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model controls an electric push rod to push a sliding ring forward, which slides on the surface of a connecting column. This causes the drive bar to push the connecting bar outward until the airbag is close to the inside of the pipe. At this time, the weld seam is located inside the airbag. Simultaneously, the fan is started, and the airflow passes through the connecting pipe, through hole, bend, and telescopic pipe in sequence to inflate the airbag. After it is full, the electronic valve is opened, and the airflow comes into contact with the inner wall of the pipe. At this time, it is possible to see whether there is any change inside the airbag. This is beneficial for convenient inspection of the weld seam after welding, ensuring the sealing of the weld and avoiding omissions that could lead to subsequent pipe use.

[0015] 2. In this utility model, the drive bar and the welding seam are located on the same horizontal plane. When welding, the servo motor is started and drives the drive plate. The fixed bar rotates with the drive plate. At this time, the camera rotates to capture images according to the welding speed, which is conducive to real-time inspection of the welding condition inside the pipe during welding.

[0024] The mounting bracket 4 has a fixed internal connection to a visualization mechanism 5, which ensures that the visualization mechanism 5 can rotate freely and follow the welding speed. The outer side of the connecting column 3 is movably connected to a leak detection mechanism 6.

[0025] Example 2

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The present invention preferably provides the following technical solution: The leak detection mechanism 6 includes a connecting bar 601, an airbag 602, an electronic valve 603, a drive bar 604, and a telescopic tube 605. Several connecting bars 601 are arranged in a circular array, and the drive bars 604 are movably connected to the bottom end of the connecting bar 601 via rotating shafts. The airbag 602 is fixedly connected to the outside of the connecting bar 601. Several electronic valves 603 are installed inside the airbag 602. The telescopic tube 605 is fixedly connected to the bottom of the connecting bar 601, and the top end of the telescopic tube 605 penetrates the connecting bar 601 and the airbag 602 and communicates with the interior of the airbag 602. The airbag 602 is annular, and its cross-section... The connecting rod 601 is arc-shaped and has a sliding ring 7 slidably connected to the surface of the connecting column 3. The end of the driving rod 604 away from the connecting rod 601 is movably connected to the surface of the sliding ring 7 through a rotating shaft. An electric push rod 8 is fixedly connected to the side of the support frame 2 near the connecting column 3, and the output end of the electric push rod 8 is fixedly connected to the outside of the sliding ring 7. A through hole 9 is opened horizontally inside the connecting column 3, and a bent pipe 10 is fixedly connected to one end of the through hole 9. The other end of the bent pipe 10 is fixedly connected to the bottom end of the telescopic pipe 605. A fan 11 is fixedly connected to the surface of the base 1, and a connecting rod is fixedly connected to one end of the fan 11. One end of the connecting pipe 12 passes through the connecting column 3 and communicates with the through hole 9.

[0027] By controlling the electric push rod 8 to push the sliding ring 7 forward and slide it on the surface of the connecting column 3, the drive bar 604 pushes the connecting bar 601 outward until the airbag 602 is close to the inside of the pipe. At this time, the weld seam is located inside the airbag 602. At the same time, the blower 11 is started and the airflow passes through the connecting pipe 12, through hole 9, bend pipe 10 and telescopic pipe 605 in sequence to inflate the airbag 602. After it is full, the electronic valve 603 is opened and the airflow comes into contact with the inner wall of the pipe.

This is conducive to the inspection of the weld seam after the welding is completed, ensuring the sealing of the weld and avoiding omissions that could lead to the use of the pipe later.

[0028] Example 3

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The present invention preferably provides the following technical solution: The visualization mechanism 5 includes a servo motor 501, a drive disk 502, a fixing bar 503, and a camera 504. The drive disk 502 is fixedly connected to the output end of the servo motor 501 via a coupling. The fixing bars 503 are symmetrically arranged and fixedly connected to the outside of the drive disk 502. The cameras 504 are respectively fixedly connected to one end of the fixing bars 503. The servo motor 501 is fixedly connected to the inside of the mounting bracket 4, and the fixing bars 503 are all located on the outside of the fixing bars 503. Since the drive bar 504 is on the same horizontal plane as the welding seam, when welding is performed, the servo motor 501 is started and drives the drive disk 502. The fixing bars 503 rotate with the drive disk 502. At this time, the camera 504 rotates to capture images according to the welding speed, which is beneficial for real-time inspection of the welding condition inside the pipe during welding.

[0030] Based on the above embodiments 1, 2, and 3, the working principle is further described. During use, the base 1 is pushed into the pipe to be welded, so that its drive bar 604 is on the same horizontal plane as the weld seam. During welding, the servo motor 501 is activated, driving the drive disc 502. The fixing bar 503 rotates with the drive disc 502. At this time, the camera 504 rotates to capture images according to the welding speed. The base 1 is continued to be pushed, so that the weld seam is located in the center of the airbag 602. Simultaneously, the electric push rod 8 is controlled to push the sliding ring 7 forward, sliding it on the surface of the connecting column 3, causing its drive bar 604 to push the connecting bar 601 outwards until the airbag 602 is close to the inside of the pipe. At this time, the weld seam is located inside the airbag 602. Simultaneously, the fan 11 is activated, and airflow sequentially passes through the connecting pipe 12, through hole 9, bend 10, and telescopic pipe 605 to inflate the airbag 602. After inflating, the electronic valve 603 is opened, and the airflow contacts the inner wall of the pipe. At this time, it is observed whether there are any changes inside the airbag 602.
