The device also comprises a fixed seat 111, a rotating frame 112, a limiting rope 1121, a connecting wheel 113, a telescopic polishing sheet 114 and a second guide pipe 115; the mounting shell 104 is fixedly connected with a fixing seat 111; the fixed seat 111 is rotatably connected with a rotating frame 112 through a torsion spring; the rotating frame 112 is fixedly connected with a limiting rope 1121, the limiting rope 1121 passes through the mounting shell 104 and is fixedly connected with the rotating plugging sheet 1032, and the limiting rope 1121 is in a tightening state; the rotating frame 112 is fixedly connected with a hollow connecting wheel 113, an electric motor is arranged in the connecting wheel 113, and the electric motor of the connecting wheel 113 is electrically connected with the equipment assembly 1; the electric motor of the connecting wheel 113 is rotationally connected with two telescopic polishing sheets 114, and the connecting wheel 113 is communicated with the telescopic polishing sheets 114; the telescopic bar 108 is communicated with and fixedly connected with a second conduit 115, and the second conduit 115 is communicated with the fifth wheel 113.
The air jet strip 1010 is also included, and the hollow chute strip 106 is fixedly connected with the air jet strip 1010 which is arranged obliquely upwards with the front-to-back reference nozzle; an adapter bend 105a is communicated between the first conduit 105 and the hollow chute bar 106.
Before the device is used, the air inlet 102a is connected with the external pump, the equipment assembly 1 is started to supply power to the welding gun 2, so that welding rods of the welding gun 2 are aligned to welding seams of the pipelines 3 to be connected to start welding, strong sea wind always blows to marine engineering equipment, the pipelines are transmission media of fresh water, fuel and other resources, if the pipelines are damaged, instant repair is needed, and therefore, in actual welding work, a welder always needs to perform the welding work in sea wind weather, the hand shaking amplitude of the welder is larger during welding, and the welding rods are positioned inaccurately, so that a welding port has low quality and affects the service life of the subsequent pipeline;
Therefore, before the welding work is carried out, the hollow driving bent bar 103 is manually stirred, the limiting bar 107 stretches into the welding seam of the pipeline 3 to be connected, then the external pump is started to input air into the hollow limiting shell 102, the hollow limiting shell 102 inputs air into the first conduit 105 through the hollow driving bent bar 103, the first conduit 105 inputs air into the telescopic bar 108, the telescopic bar 108 is blown in by the air to be unfolded, the telescopic bar 108 drives the connected second elastic piece 109 to be unfolded, at the moment, the second elastic piece 109 generates reset elastic force, at the moment, the limiting bar 107 is pushed by the telescopic bar 108 to be clamped between the welding seams and can not be easily pulled out or swayed left and right, the limiting bar 107 is provided with rotating beads, the rotating beads enable the limiting bar 107 to slide on the welding seam, and the limiting bar 107 sequentially passes through the hollow sliding groove bar 106, the mounting shell 104 and the hollow driving bent bar 103, the spacing bar 107 is forced on the hollow spacing shell 102, at this time, the hollow spacing shell 102 cannot shake left and right, but only can rotate around the welding seam of the pipeline 3 to be connected under the action of the spacing bar 107 in the subsequent welding work, and because the welding gun 2 is connected with the hollow spacing shell 102 through the first elastic piece 101, and a certain gap exists between the welding gun 2 and the hollow spacing shell 102, the welding seam is welded manually, the welding gun 2 is limited by the fixed hollow spacing shell 102, the welding gun 2 can only swing in the annular area in the hollow spacing shell 102 and cannot shake greatly, so that the problem that the shaking amplitude is large and the welding rod is positioned inaccurately is greatly reduced, and a certain friction force exists between the spacing bar 107 and the welding seam, when a worker holds the welding gun 2 to rotate around the pipeline 3 to be connected, the friction force suffered by the spacing bar 107 can act on the hollow spacing shell 102, the hollow limiting shell 102 limits the welding gun 2, so that resistance is applied to the welding gun 2, and the problem of cold joint caused by too high welding speed is greatly reduced when a worker works by using the welding gun 2, so that the positioning accuracy of welding work is realized, and the welding quality is improved;
Furthermore, impurities, rust and dust adhere to a welded joint of a pipeline, the substances can affect the welding quality, so that the pipeline needs to be polished before welding, but because the area required to be polished is large, the mode of directly polishing by using a polisher is long, so that the welding efficiency is low, in the actual welding operation, the pipeline 3 to be connected is welded with the fixing strip 4 for fixing, at the moment, the fixing strip 4 can obstruct the sliding of the limiting strip 107, if other fixing devices are used for fixing the pipeline 3 to be connected, the convenience of the welding operation is reduced, when the limiting strip 107 stretches into a welding line of the pipeline 3 to be connected, the connecting wheel 113 stretches into the welding line at the same time, when the telescopic strip 108 is subjected to air blowing by an external pump, the telescopic strip 108 enters into a polishing wheel formed by the connecting wheel 113 and the telescopic polishing sheet 114 through the second conduit 115, at the moment, the telescopic polishing sheet 114 is subjected to air blowing and begins to be spread and contacted with the welding line, when a worker welds the welded joint of the pipeline 3 to be connected by using the handheld welding gun 2, the electric motor of the connecting wheel 113 is controlled, the electric motor of the connecting wheel 113 is driven, and the required time for polishing the joint 114 is greatly reduced;
When the connecting wheel 113 rotates around the welded junction of the pipeline 3 to be connected, if the connecting wheel 113 contacts the fixed strip 4, the connecting wheel 113 is extruded by the fixed strip 4 and is far away from the fixed strip 4, the connecting wheel 113 drives the connected rotating frame 112 to rotate around the fixed seat 111, the rotating frame 112 drives the connected limiting rope 1121 to be converted into a loose state from a tight state when rotating, at the moment, the rotating blocking piece 1032 loses the pulling limit of the limiting rope 1121, the rotating blocking piece 1032 rotates towards the air guide opening direction of the first conduit 105 under the action of the torsion spring, the air guide opening of the first conduit 105 is blocked after the rotating blocking piece 1032 rotates to the limit position, and at the moment, the first conduit 105 does not convey air to the telescopic strip 108;
The air in the telescopic strip 108 continuously flows out of the limiting strip 107 under the condition that no follow-up supply is carried out, at this moment, the telescopic strip 108 loses the support of the air, at this moment, the reset elastic force of the second elastic piece 109 is larger than the unfolding force of the telescopic strip 108, the telescopic strip 108 is driven to shrink, the telescopic strip 108 drives the connected limiting strip 107 to reset, at this moment, the limiting strip 107 cannot be clamped in a welding seam, the reset of the limiting strip 107 can not limit the rotation of the mounting shell 104 any more, at this moment, the mounting shell 104 is fixedly connected with the hollow transmission bent strip 103 through a torsion spring, the movement of the connecting wheel 113 drives the mounting shell 104 to rotate around the hollow transmission bent strip 103, the mounting shell 104 drives the connected parts to rotate, at this moment, the mounting shell 104 is in a state of being low left and high, and the connected parts of the mounting shell 104 can pass over the fixing strip 4, so that the mounting shell 104 can not limit welding personnel to perform welding work, the welding work can not be influenced by the fixing strip 4, and the fixing device for fixing the pipeline 3 is convenient to use, if the welding work is reduced;
Further, when the telescopic polishing sheet 114 polishes the weld, impurities such as metal scraps and rust, etc. which are polished down adhere to the telescopic polishing sheet 114, so that the polishing function of the telescopic polishing sheet 114 is weakened; therefore, the first conduit 105 guides air into the hollow chute bar 106 through the switching elbow 105a, taking fig. 9 as an example, the hollow chute bar 106 sprays air from the air spraying bar 1010 to the telescopic polishing sheet 114 in an obliquely upward direction, so that impurities adhered on the telescopic polishing sheet 114 can be cleaned, and polishing work of the telescopic polishing sheet 114 can be smoothly performed.

When the connecting wheel 113 is extruded by the fixing strip 4 to drive the limiting strip 107 to shrink, the hollow limiting shell 102 loses the positioning limitation of the limiting strip 107, at this time, the hollow limiting shell 102 cannot limit the welding gun 2, and if the hand of a welder shakes at this time, the welding quality is affected;
Before a welder holds the device to perform welding work, the fixed rod 202 is manually stirred, a slag scraping plate formed by the telescopic sheet 203, the scraping blade 204, the elastic strip 205 and the clamping sheet 208 is stretched into a welded junction of a pipeline 3 to be connected through the fixed rod 202, then the external pump is connected with the gas transmission port 203a, at the moment, the external pump is controlled to guide air into the slag scraping plate, at the moment, the interior of the slag scraping plate is stretched by blowing air, so that the slag scraping plate can be suitable for welded junctions with different widths, and the scraping blade 204 is made of hard materials, so that the slag scraping plate can normally perform work in the subsequent slag scraping work;
When welding work is performed, when the connecting wheel 113 is extruded by the fixing strip 4, the connecting wheel 113 drives the rotating frame 112 to rotate, the rotating frame 112 can extrude the telescopic air bag 2010 when rotating, air in the telescopic air bag 2010 is quantitative, after being extruded, the air in the telescopic air bag 2010 can be transmitted to the telescopic air pipe 206 through the air supply pipe 209, at the moment, the telescopic air pipe 206 inputs the air into the telescopic bin 207, at the moment, the telescopic bin 207 is further expanded by blowing the air, the telescopic bin 207 drives the connected card 208 to be further expanded, at the moment, the card 208 is contacted with a welded junction of a pipeline 3 to be connected before, the card 208 is further expanded, so that the slag scraping plate can be clamped at the welded junction, and the card 208 is provided with the rolling ball 208a, so that the slag scraping plate can rotate around the welded junction of the pipeline 3 to be connected, and the slag scraping plate is connected with the hollow limiting shell 102 through the fixing rod 202 and the fixing frame 201, so that the slag scraping plate can limit the hollow limiting shell 102, at the moment, the limiting work of the limiting strip 107 is replaced, and the hollow limiting shell 102 can limit the welding gun 2 in the whole welding process, so that the welding work can be further optimized;
When welding work is performed, a layer of welding slag is left on a welding line formed by welding the welding electrode after the welding electrode is melted, the welding slag needs to be cleaned in time after the welding of the pipeline 3 to be connected is completed, otherwise, the welding slag stays for a long time in the welding line, which is not beneficial to the cooling and crystallization processes in the welding line, the hydrogen diffusion and other chemical reactions, but the welding slag is cleaned uniformly after the pipeline 3 to be connected is completely welded in the prior art for the convenience and consistency of work, so that the welding line cannot be cooled in time, and the quality of the welding work is greatly influenced;
Further, when a welder holds the welding gun 2 to rotate around the pipeline 3 to be connected for welding, the welding gun 2 drives the connected fixing frame 201 to move, the fixing frame 201 drives the connected fixing rod 202 to move, and the fixing rod 202 drives the connected slag scraping plate to move;
When the welding line is generated by welding work through rotation of the pipeline to be connected 3, when the slag scraping plate moves to the welding line, the welding line is cooled for a period of time, the time for hardening after welding rods are melted is only 5-9 seconds, the welding line is preliminarily hardened, and the slag scraping plate directly scrapes off the welding slag when contacting the welding line, so that the welding slag is scraped immediately and rapidly, the welding slag is treated during welding, the cooling performance of the welding line is improved, the welding slag is not required to be treated in the follow-up work, and the welding work efficiency is improved.
Example 3
On the basis of the embodiment 2, as shown in fig. 2-6, the magnetic plate also comprises a sliding limiting pin 301, a magnetic block 302 and a magnetic sheet 303; the welding gun 2 is fixedly connected with a magnetic block 302; the welding gun 2 is inserted with a sliding limiting pin 301, and the sliding limiting pin 301 is magnetically connected with a magnetic block 302; the welding gun 2 is fixedly connected with a magnetic sheet 303.
The device also comprises a sensor 304, a third electric push rod 305 and an inductor 306; the welding gun 2 is fixedly connected with a sensor 304; the sensor 304 is fixedly connected with a third electric push rod 305; the third electric push rod 305 is in contact with the sliding limit pin 301; the inner annular surface of the hollow limit shell 102 is fixedly connected with the inductors 306, and all the inductors 306 are electrically connected with the sensor 304.
Because the hollow limiting shell 102 is connected with the welding gun 2 through the first elastic piece 101, the hollow limiting shell 102 and the welding gun 2 are not hard-connected due to the elastic characteristic of the first elastic piece 101, when the device is not in operation and stored in a tool box, the hollow limiting shell 102 can continuously vibrate and strike the welding gun 2, the device is not easy to store, and a welder takes tools in daily operation, so that convenience in tool taking is emphasized, commonly used welding rods, iron wires and other parts and welding tools are usually placed in the tool box together, and because gaps exist between the hollow limiting shell 102 and the welding gun 2, the welding rods and the iron wires can be clamped in the gaps to influence the use of the device;
therefore, before the device is stored, the sliding limiting pin 301 can be manually pushed, so that the sliding limiting pin 301 is clamped in the gap between the hollow limiting shell 102 and the welding gun 2, and when the sliding limiting pin 301 is completely clamped in the gap, the sliding limiting pin 301 contacts the magnetic sheet 303, and at the moment, the magnetic sheet 303 magnetically adsorbs the sliding limiting pin 301, so that the stability of the device during storage is realized, and external parts are blocked from being clamped in the gap of the device;
Further, in the device, when welding the pipeline, although the welding gun 2 is limited by the limiting bar 107, the welding swing of a welder can be prevented from being too large, in the actual welding work, as the pipeline is welded by the hand-held device, the wind force of sea wind changes at any time, when the sea wind suddenly and rapidly increases during the welding work, the hand is severely vibrated, and at the moment, the limiting force of the limiting bar 107 is not too strong due to the need of considering the follow-up moving work, so that the limiting bar 107 is insufficient to deal with the large-amplitude swing of the hand of the welder;
Therefore, when a welder holds the welding gun 2 and violently shakes, the welding gun 2 swings to strike the hollow limiting shell 102, at the moment, the inductor 306 connected to the hollow limiting shell 102 is triggered, an electric signal is transmitted to the sensor 304 by the inductor 306, at the moment, the sensor 304 drives the third electric push rod 305 to push the sliding limiting pin 301 to move towards the hollow limiting shell 102, at the moment, the sliding limiting pin 301 is inserted into a gap between the hollow limiting shell 102 and the welding gun 2, so that the welding gun 2 is extruded by the sliding limiting pin 301 and corrected to a position coaxial with the hollow limiting shell 102, and the problem that the welding gun 2 is violently shaked during welding, and further the welding quality is affected is solved.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes or direct or indirect application in other related arts are included in the scope of the present invention.
