Description

Technical Field

[0001] This utility model belongs to the field of steel welding technology, and in particular relates to a steel welding device. Background Technology

[0002] Steel pipe welding is a very common connection method in the industrial field. Its main purpose is to connect multiple sections of steel pipe into a whole to meet the needs of different scenarios.

[0003] For example, Chinese patent CN221849219U discloses a steel welding device with positioning function, including: a movable base, a welding machine on one side of the movable base, and a convenient mechanism on the top of the movable base; by setting the convenient mechanism, when it is necessary to put the steel pipe on the rotating rod, the two movable support plates facilitate the placement of the steel pipe after the two rotating rods are staggered, which improves the convenience of placing the steel pipe. By setting the docking component, the cooperation between the first docking block and the second docking block helps to make the two rotating rods form a whole with the same center, thereby ensuring the stability of the two steel pipes during welding. In the interaction between the limiting block and the limiting groove, only the second motor needs to be started to drive one rotating rod to rotate synchronously to drive the other rotating rod, which improves the consistency of rotation when welding the two steel pipes and helps to reduce the cumbersome operation of the welding staff.

[0004] The aforementioned patent has the following problems:

[0005] The patented device has some drawbacks in use, such as the fact that after welding, the steel pipe is fitted onto the two rotating rods, making it inconvenient to remove the welded steel pipe from the two rods and reducing welding efficiency. Therefore, we propose a steel welding device. Utility Model Content

[0006] The purpose of this invention is to provide a steel welding device to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a steel welding device, including a base and a welding machine body, and further comprising:

[0008] A fixed frame is fixedly installed on a base, and a hydraulic cylinder is fixedly installed on the top of the fixed frame. The telescopic end of the hydraulic cylinder passes through the fixed frame, and the welding machine body is fixedly installed on the telescopic end of the hydraulic cylinder.

[0009] A fixed base is fixedly installed on the base and located below the welding machine body. A power cavity is opened in the fixed base. Two discs are rotatably installed in the power cavity. Each of the two discs has a rotating groove. Several sliding strips are slidably installed in each of the two rotating grooves. One end of each of the sliding strips passes through the two rotating grooves and extends to the outside.

[0010] A drive assembly, located within a fixed base, is used to drive the two disks to rotate;

[0011] Two sets of power components are located in two disks respectively, and are used to drive several sliding bars to slide.

[0012] In this technical solution, when it is necessary to weld steel pipes, one of the steel pipes is first placed in one of the discs. Through the set power component, several sliding bars can be driven to slide and move closer to each other. The several sliding bars can clamp and fix one of the steel pipes. Through the above operation, the position of another steel pipe can also be fixed.

[0013] Then, the hydraulic cylinder is activated, which drives the welding machine body to move downwards. The welding machine body can then weld two steel pipes. Through the set drive component, two discs can be driven to rotate, and the two discs drive the two steel pipes to rotate simultaneously, ensuring that the welding machine body can fully weld the joint of the two steel pipes without the need for manual operation by the staff, thus speeding up the welding efficiency. After the welding is completed, the fixation of the two steel pipes is removed, and then the welded steel pipes can be pulled out.

[0014] In the above technical solution, the driving component further includes:

[0015] The first motor is fixedly mounted on a fixed base. The output shaft of the first motor passes through the fixed base and extends into the power cavity. Two first gears are fixedly mounted on the output shaft of the first motor. Several tooth blocks are fixedly mounted on each of the two discs. The two first gears mesh with the several tooth blocks respectively. Both first gears are rotatably connected to the power cavity.

[0016] In this technical solution, the first motor is started, which drives two first gears to rotate. The two first gears, through several meshing tooth blocks, can drive two discs to rotate respectively. The two discs drive two steel pipes to rotate simultaneously, ensuring that the welding machine body can fully weld the joint of the two steel pipes without the need for manual operation by the staff, thus speeding up the welding efficiency. After the welding is completed, the fixation of the two steel pipes is removed, and then the welded steel pipes can be pulled out.

[0017] In the above technical solution, the power component further includes:

[0018] A gear ring is rotatably mounted in a rotating groove. A plurality of second gears are meshed on the inner side of the gear ring. A third gear is fixedly mounted at one end of each of the second gears. A rack is meshed on one side of each of the third gears. The racks are fixedly connected to a plurality of sliding bars. A second motor is fixedly mounted in the rotating groove, located on one side of one of the third gears. The output shaft of the second motor is coaxially connected to one of the third gears. The second gears and the third gears are rotatably connected to the rotating groove, and the racks are slidably connected to the rotating groove.

[0019] In this technical solution, when welding steel pipes is required, one steel pipe is first placed in a fixed plate and a disc. Then, a second motor is started, which drives a third gear to rotate. The third gear drives a second gear to rotate, which drives a gear ring meshing with it to rotate. The gear ring drives the remaining second gears meshing with it to rotate, and the remaining second gears drive the remaining third gears to rotate. The remaining third gears drive the racks meshing with them to slide and move closer to each other. The racks drive the sliding strips to slide and move closer to each other. The sliding strips drive the anti-slip rubber pads to clamp and fix one steel pipe. The above operation can also fix the position of another steel pipe.

[0020] In the above technical solution, the telescopic end of the hydraulic cylinder is slidably connected to the fixed frame, and the output shaft of the first motor is rotatably connected to the fixed seat and the power cavity.

[0021] In this technical solution, the telescopic end of the hydraulic cylinder can slide within the fixed frame, ensuring that the output shaft of the first motor can rotate within the fixed seat and the power chamber.

[0022] In the above technical solution, furthermore, a storage battery is fixedly installed in each of the two rotating slots, and the two storage batteries are electrically connected to the two second motors respectively.

[0023] In this technical solution, the installed battery ensures that both second motors can be powered on and operate.

[0024] In the above technical solution, furthermore, one end of each of the sliding strips is fixedly installed with an anti-slip rubber pad.

[0025] In this technical solution, the anti-slip rubber pads are used to ensure the stability of the steel pipe.

[0026] In the above technical solution, furthermore, a fixing plate is fixedly installed on the top of the base and on both sides of the fixing seat.

[0027] In this technical solution, the fixed plates ensure that both ends of the steel pipe are supported and will not tilt.

[0028] In the above technical solution, further, several of the sliding bars are distributed in a ring at equal intervals within the two disks.

[0029] In this technical solution, the stability of the steel pipe is ensured by setting several sliding bars.

[0030] The beneficial effects of this utility model are:

[0031] When welding steel pipes, this steel welding device first places one of the steel pipes in one of the discs. A power component drives several sliding bars to slide and move closer together, clamping and fixing one of the steel pipes. This process also fixes the position of the other steel pipe. A drive component rotates two discs, each rotating one of the two steel pipes simultaneously, ensuring the welding machine can fully weld the joint between the two pipes. No manual operation is required, significantly increasing welding efficiency. After welding, the fixing of the two steel pipes is removed, and the welded pipe can then be extracted.

[0046] Example 1: This example provides a steel welding device, including a base 1 and a welding machine body 4, and further including:

[0047] The fixed frame 2 is fixedly installed on the base 1. A hydraulic cylinder 3 is fixedly installed on the top of the fixed frame 2. The telescopic end of the hydraulic cylinder 3 passes through the fixed frame 2. The welding machine body 4 is fixedly installed on the telescopic end of the hydraulic cylinder 3.

[0048] The fixed base 5 is fixedly installed on the base 1 and located below the welding machine body 4. The fixed base 5 has a power cavity 6. Two discs 7 are rotatably installed in the power cavity 6. Each of the two discs 7 has a rotating groove 9. Several sliding strips 10 are slidably installed in each of the two rotating grooves 9. One end of each sliding strip 10 passes through the two rotating grooves 9 and extends to the outside.

[0049] The drive assembly is located inside the fixed base 5 and is used to drive the two disks 7 to rotate;

[0050] Two sets of power components are located in two disks 7 respectively, and are used to drive several sliding bars 10 to slide.

[0051] When welding is required on the steel pipes, one of the steel pipes is first placed in one of the discs 7. Through the power component, several sliding bars 10 can be driven to slide and move closer to each other. The several sliding bars 10 can clamp and fix one of the steel pipes. Through the above operation, the position of the other steel pipe can also be fixed.

[0052] Then, the hydraulic cylinder 3 is activated, which drives the welding machine body 4 to move downward. The welding machine body 4 can weld two steel pipes. Through the set drive component, it can drive two discs 7 to rotate. The two discs 7 drive the two steel pipes to rotate simultaneously, ensuring that the welding machine body 4 can fully weld the connection between the two steel pipes without the need for manual operation by the staff, which speeds up the welding efficiency. After the welding is completed, the fixation of the two steel pipes is removed, and then the welded steel pipes can be pulled out.

[0053] In this embodiment, the driving component includes:

[0054] The first motor 11 is fixedly mounted on the fixed base 5. The output shaft of the first motor 11 passes through the fixed base 5 and extends into the power cavity 6.

[0055] The process involves starting the first motor 11, which drives two first gears 12 to rotate. These first gears 12, through several meshing tooth blocks 8, can respectively drive two discs 7 to rotate. The two discs 7 then drive two steel pipes to rotate simultaneously, ensuring that the welding machine body 4 can fully weld the connection between the two steel pipes without requiring manual operation by staff, thus accelerating the welding efficiency. After welding is completed, the fixation of the two steel pipes is removed, and the welded steel pipes can then be extracted.

The several racks 16 are slidably connected to the rotating groove 9.

[0058] When welding is required on the steel pipes, one of the steel pipes is first placed inside a fixed plate 20 and a disc 7. Then, a second motor 17 is started, which drives a third gear 15 to rotate. The third gear 15 drives a second gear 14 to rotate, and the second gear 14 drives a gear ring 13 meshing with it to rotate. The gear ring 13 drives the remaining second gears 14 meshing with it to rotate. The remaining second gears 14 drive the remaining third gears 15 to rotate. The remaining third gears 15 drive the racks 16 meshing with them to slide and move closer to each other. The racks 16 drive the sliding strips 10 to slide and move closer to each other. The sliding strips 10 drive the anti-slip rubber pads 18 to clamp and fix one of the steel pipes. The position of the other steel pipe can also be fixed through the above operation.

[0060] In this embodiment, the telescopic end of the hydraulic cylinder 3 is slidably connected to the fixed frame 2, and the output shaft of the first motor 11 is rotatably connected to the fixed seat 5 and the power chamber 6.

[0061] Specifically, it ensures that the telescopic end of the hydraulic cylinder 3 can slide within the fixed frame 2, and that the output shaft of the first motor 11 can rotate within the fixed seat 5 and the power chamber 6.
