Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and specifically to a reinforced welding device for steel pipe butt welding. Background Art

[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. There are many energy sources for modern welding, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasonic waves. In addition to being used in factories, welding can also be carried out in various environments, such as outdoors, underwater, and in space. No matter where it is, welding may pose risks to operators, so appropriate protective measures must be taken during welding. The injuries that welding may cause to the human body include burns, electric shock, vision damage, inhalation of toxic gases, excessive ultraviolet radiation, etc. Steel pipes often need to be welded during use.

[0003] Patent No. CN112122868B discloses a reinforced welding device for steel pipe butt welding, belonging to the technical field of welding equipment. It can be realized that there is a special steel pipe clamping and rotating mechanism, which can not only clamp and fix the steel pipe, but also rotate the steel pipe during welding, thus facilitating the operation of workers to weld the side and bottom of the steel pipe, significantly improving the welding efficiency. It is also provided with a reinforcement component. Through simple operations, the reinforcement connection ring in the reinforcement component can be bonded to the welding joint of the steel pipe, thereby greatly improving the strength of the butt joint of the steel pipe, effectively avoiding fracture and leakage at the butt joint, and improving the safety performance. It is also provided with a connection sliding component, which can not only support the reinforcement component, but also facilitate the movement of the reinforcement component, and the connection sliding component is easily separated from the reinforcement connection ring, thus facilitating the extraction of the steel pipe after butt welding is completed, greatly improving the practicability and convenience during use.

[0004] However, there are some problems in the use of existing reinforced welding devices for steel pipe butt welding. 1. When the existing reinforced welding devices for steel pipe butt welding on the market are in use, their overall rotational adjustability for steel pipes is relatively low, making it inconvenient for circumferential welding and increasing the overall welding difficulty. 2. When the existing reinforced welding devices for steel pipe butt welding on the market are in use, their overall fixity is relatively low, making it inconvenient for stable clamping welding, so that the welding is prone to misalignment, resulting in welding quality problems. 3. During the welding process of the existing reinforced welding devices for steel pipe butt welding on the market, there is a lack of a measure for rapid cooling, so it is necessary to wait for the cooling time of the steel pipe welding, reducing the overall welding efficiency.

[0015] A usage method of a reinforced welding device for steel pipe butt joint includes the following steps: Step 1: When in use, the support seat supports the bottom plate, the controller detachably connected to the surface of the bottom plate controls all its electrical appliances, the connecting columns are installed through the connection ports formed at both ends of the bottom plate, and the guide plate is fixed through the connecting columns. When the steel pipe body is imported for welding, the user can place the steel pipe body into the guide holes formed on the surface of the guide plate. Step 2: When circumferential welding is required for the preliminary welding of the steel pipe body, the controller is used to connect the power current input end of the driver. The driver works to drive the rotating wheel cooperatively connected with it to rotate. The rotating wheel rotates the steel pipe body through the rubber sleeve fitted on its surface, so as to perform circumferential welding. The driver is installed on the top of the guide plate through the housing. Step 3: When performing mobile clamping, the steel pipe body is placed in the placement openings formed on the surfaces of the upper clamping plate and the lower clamping plate. The placement openings place the steel pipe body through the sponge layer. By matching the bolts with the screw holes formed on the surfaces of the upper clamping plate and the lower clamping plate, the steel pipe body can be fixed by the upper clamping plate and the lower clamping plate. At this time, the controller is used to connect the power current input ends of a plurality of telescopic rods. The telescopic rods work to drive the embedded blocks to move in the embedded grooves, so as to drive the lower clamping plate fixedly connected to the support block to move and simultaneously drive the steel pipe body to move, and convey it to the bottom of the bracket. Step 4: Connecting plates are installed at both ends of the telescopic rod. One end of the connecting plate is installed with the mounting block fitted on the surface of the embedded block. Connecting holes are formed on the surfaces of the connecting plate and the mounting block. A fixing column is inserted into the connecting holes to install the telescopic rod. Step Five: When welding, the controller is used to connect the power current input terminal of the welder. The welder operates to make its welding head weld the steel pipe body. During the welding process, the controller is used to connect the power current output terminal of the motor. The motor operates to drive the input end of the rotating shaft connected to its output end to rotate. The rotating shaft then drives the fan blade connected to one end to rotate to generate wind power. The wind power dissipates heat from the steel pipe body welded inside the bracket through the openings provided at both ends of the bracket surface. The motor is installed inside the box body through the mounting rod. The inside of the box body is hollow. One end of the box body is detachably connected with a filter plate, and the other end is aligned and connected with the opening.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The two ends of the bottom plate are used to install the connecting columns through the provided connecting ports, and the guide plate is fixed through the connecting columns. When the steel pipe body is imported for welding, the user can place the steel pipe body into the guide holes provided on the surface of the guide plate. The steel pipe body is guided through the guide holes, increasing the overall guiding property. When the steel pipe body needs to be circumferentially welded during the preliminary welding, the controller is used to connect the power current input terminal of the driver. The driver operates to drive the rotating wheel connected to it to rotate. The rotating wheel rotates the steel pipe body through the rubber sleeve fitted on its surface. The friction force is increased through the rubber sleeve, making it convenient to rotate the steel pipe for circumferential welding. The driver is installed on the top of the guide plate through the housing, and the driver is protected and installed through the housing, increasing the protection property. Then, when the steel pipe butt joint reinforced welding device is in use, its overall rotational adjustability for the steel pipe is relatively high, making it convenient for circumferential welding and reducing the overall welding difficulty.

[0017] 2. The steel pipe body is placed in the placement openings formed on the surfaces of the upper clamping plate and the lower clamping plate. The placement openings are used to place the steel pipe body through a sponge layer. The sponge layer reduces the damage to the steel pipe body during squeezing and clamping, reducing the occurrence of deformation problems. By matching and connecting bolts with the screw holes formed on the surfaces of the upper clamping plate and the lower clamping plate, the steel pipe body can be fixed by the upper clamping plate and the lower clamping plate, increasing the overall clamping and fixing property. At this time, the controller is used to connect the power current input ends of multiple telescopic rods. The telescopic rods work to drive the insertion blocks to move in the insertion grooves, thereby driving the lower clamping plate fixedly connected to the support block to move and simultaneously driving the steel pipe body to move, thus increasing the overall transportation guiding property, making it convenient to guide the steel pipe body during welding. It is transported to the bottom of the bracket. Both ends of the telescopic rods are provided with connecting plates. One end of the connecting plate is installed with an installation block that is matched with the surface of the insertion block. Connecting holes are formed on the surfaces of the connecting plate and the installation block. Fixing columns are inserted into the connecting holes to increase the overall connection and installation property, facilitating the installation of the telescopic rods. Then, when the reinforced welding device for steel pipe butt joint is in use, the overall fixing property is relatively high, facilitating stable clamping and welding, so that the welding is not likely to be misaligned, reducing welding quality problems.

[0018] 3. The controller is used to connect the power current input end of the welding machine. The welding machine works to make its welding head weld the steel pipe body. During the welding process, the controller is used to connect the power current output end of the motor. The motor works to drive the input end of the rotating shaft connected to its output end to rotate. The rotating shaft drives the fan blades connected to one end to rotate to generate wind. The wind dissipates heat from the steel pipe body welded inside the bracket through the openings formed at both ends of the surface of the bracket, reducing the overall cooling time and increasing the overall welding efficiency. The motor is installed inside the box body through a mounting rod. The inside of the box body is hollow, making it convenient for ventilation. One end of the box body is detachably connected with a filter plate to reduce the entry of external sundries. The other end is aligned and connected with the opening, making it convenient for wind guiding and heat dissipation. Then, during the welding process of the reinforced welding device for steel pipe butt joint, there is a measure to quickly cool it, thereby reducing the cooling time waiting for the steel pipe welding and improving the overall welding efficiency.

[0030] A usage method of a reinforced welding device for steel pipe butt joint includes the following steps: Step 1: When in use, the support base supports the bottom plate 1. The controller detachably connected to the surface of the bottom plate 1 controls all its electrical appliances. The connecting columns 202 are installed at both ends of the bottom plate 1 through the connecting ports 201 provided, and the guide plate 203 is fixed through the connecting columns 202. When the steel pipe body 3 is introduced for welding, the user can place the steel pipe body 3 into the guide holes 204 provided on the surface of the guide plate 203. Step 2: When circumferential welding is required for the preliminary welding of the steel pipe body 3, the controller turns on the power current input end of the driver 206. The driver 206 works to drive the rotating wheel 207 connected to it to rotate. The rotating wheel 207 rotates the steel pipe body 3 through the rubber sleeve 208 fitted on its surface, so as to perform circumferential welding. The driver 206 is installed on the top of the guide plate 203 through the housing 205. Step 3: When performing moving clamping, the steel pipe body 3 is placed in the placement openings 411 provided on the surfaces of the upper clamping plate 410 and the lower clamping plate 409. The placement openings 411 place the steel pipe body 3 through the sponge layer 412. By matching with the screw holes 413 provided on the surfaces of the upper clamping plate 410 and the lower clamping plate 409 through bolts, the steel pipe body 3 can be fixed by the upper clamping plate 410 and the lower clamping plate 409. At this time, the controller turns on the power current input ends of multiple expansion rods 405. The expansion rods 405 work to drive the insert block 402 to move in the insert groove 401, so as to drive the lower clamping plate 409 fixedly connected to the support block 408 to move and simultaneously drive the steel pipe body 3 to move, and convey it to the bottom of the bracket 501. Step 4: Connecting plates 406 are installed at both ends of the telescopic rod 405. One end of the connecting plate 406 is installed with the mounting block 403 that is fitted and connected to the surface of the insert block 402. Connecting holes 404 are provided on the surfaces of the connecting plate 406 and the mounting block 403.

Step 5: During welding, the power current input terminal of the welding torch 502 is connected through the controller. The welding torch 502 operates to make its welding head 503 weld the steel pipe body 3. During the welding process, the power current output terminal of the motor 508 is connected through the controller. The motor 508 operates to drive the input end of the rotating shaft 509 connected to its output end to rotate. The rotating shaft 509 drives the fan blade 510 connected in cooperation at one end to rotate to generate wind power. The wind power dissipates heat from the steel pipe body 3 welded inside the support 501 through the openings 504 provided at both ends of the surface of the support 501.

[0031] Working principle: Connecting columns 202 are installed at both ends of the bottom plate 1 through the provided connection ports 201, and the guide plate 203 is fixed through the connecting columns 202. When the steel pipe body 3 is guided for welding, the user can place the steel pipe body 3 into the guide holes 204 provided on the surface of the guide plate 203. The steel pipe body 3 is guided through the guide holes 204 to increase the overall guiding property. When the steel pipe body 3 needs to be circumferentially welded during preliminary welding, the power current input terminal of the driver 206 is connected through the controller. The driver 206 operates to drive the rotating wheel 207 connected in cooperation with it to rotate. The rotating wheel 207 rotates the steel pipe body 3 through the rubber sleeve 208 fitted on its surface. The friction force is increased through the rubber sleeve 208 to facilitate the rotation of the steel pipe for circumferential welding.

By cooperating and connecting the bolts with the screw holes 413 formed on the surfaces of the upper clamping plate 410 and the lower clamping plate 409, the steel pipe body 3 can be fixed by the upper clamping plate 410 and the lower clamping plate 409, increasing the overall clamping and fixing property. At this time, the controller is used to connect the power current input ends of multiple telescopic rods 405. The telescopic rods 405 work to drive the embedded blocks 402 to move in the embedded grooves 401, thereby driving the lower clamping plate 409 fixedly connected to the support block 408 to move and simultaneously driving the steel pipe body 3 to move, thus increasing the overall transportation guiding property, facilitating guiding during the welding of the steel pipe body 3, and conveying it to the bottom of the bracket 501. Both ends of the telescopic rod 405 are provided with connecting plates 406. One end of the connecting plate 406 is installed with the mounting block 403 that is cooperatively connected to the surface of the embedded block 402. Connecting holes 404 are formed on the surfaces of the connecting plate 406 and the mounting block 403. Fixing columns 407 are inserted into the connecting holes 404 to increase the overall connection and installation property and facilitate the installation of the telescopic rod 405; During the final welding, the controller is used to connect the power current input end of the welder 502. The welder 502 works to make its welding head 503 weld the steel pipe body 3. During the welding process, the controller is used to connect the power current output end of the motor 508. The motor 508 works to drive the input end of the rotating shaft 509 connected to its output end to rotate. The rotating shaft 509 drives the fan blade 510 connected to one end to rotate to generate wind power. The wind power dissipates heat from the steel pipe body 3 welded inside the bracket 501 through the openings 504 formed at both ends of the surface of the bracket 501, reducing the overall cooling time and increasing the overall welding efficiency. The motor 508 is installed inside the box body 505 through the mounting rod 507. The inside of the box body 505 is hollow, facilitating ventilation. One end of the box body 505 is detachably connected with a filter plate 506 to reduce the entry of external sundries, and the other end is aligned and connected with the opening 504 to facilitate wind power guiding and heat dissipation.

The connection columns (202) are installed at both ends of the bottom plate (1) through the connection ports (201) provided, and the guide plate (203) is fixed through the connection columns (202). When the steel pipe body (3) is imported for welding, the user can place the steel pipe body (3) into the guide holes (204) provided on the surface of the guide plate (203). Step 2: When circumferential welding is required for the preliminary welding of the steel pipe body (3), the controller turns on the power current input end of the driver (206). The driver (206) works to drive the rotating wheel (207) connected to it to rotate. The rotating wheel (207) rotates the steel pipe body (3) through the rubber sleeve (208) fitted on its surface to perform circumferential welding. The driver (206) is installed on the top of the guide plate (203) through the housing (205). Step 3: When performing mobile clamping, the steel pipe body (3) is placed in the placement openings (411) provided on the surfaces of the upper clamping plate (410) and the lower clamping plate (409). The placement openings (411) place the steel pipe body (3) through the sponge layer (412). By cooperating with the screw holes (413) provided on the surfaces of the upper clamping plate (410) and the lower clamping plate (409) through bolts, the steel pipe body (3) can be fixed by the upper clamping plate (410) and the lower clamping plate (409). At this time, the controller turns on the power current input ends of a plurality of telescopic rods (405). The telescopic rods (405) work to drive the inlay block (402) to move in the inlay groove (401), and then drive the lower clamping plate (409) fixedly connected to the support block (408) to move and drive the steel pipe body (3) to move at the same time, so as to transport it to the bottom of the bracket (501). Step Four: Connecting plates (406) are installed at both ends of the telescopic rod (405). One end of the connecting plate (406) is installed with the mounting block (403) that is fitted and connected to the surface of the insert block (402).
