Description

Technical Field

[0001] The present invention relates to the technical field of production welding, and in particular to a welding device for producing fire-fighting equipment and a method of using the same. Background Art

[0002] Firefighting pipes, as a component of firefighting equipment, are commonly used in various buildings and are one of the essential public facilities. They are mainly used to transport firefighting water. During construction, the length of each section of firefighting pipe is designed, pre-produced in the processing plant, and then transported to the installation site.

[0003] The installation environment is complex, and the pre-designed pipes were not accurately installed at the designated locations during actual installation. As a result, the ends of some pipes were located at the bottom openings or at the roof openings. These locations made it impossible to splice the upper and lower sections of the pipes, and the pipes needed to be extended by welding.

[0004] Traditional fire protection pipe welding operations have three major technical pain points: first, manual alignment relies on the operator's experience, and the pipe mouth is often misaligned, resulting in uneven welding strength; second, when the pipe clamp is clamped, the difference in the weight distribution of the pipe body causes deflection, affecting the quality of the annular weld; third, the existing adjustment device lacks quality prediction function and cannot promptly detect hidden dangers such as uneven pipe density.

[0005] In view of this, we propose a welding device for producing fire-fighting equipment and a method of using the same. Summary of the Invention

[0006] The purpose of the present invention is to provide a welding device for the production of fire-fighting equipment and a method for using the same, so as to solve the problems raised in the above-mentioned background technology, such as uneven welding strength caused by misalignment of the pipe mouth, deflection caused by differences in the weight distribution of the pipe body, affecting the quality of the annular weld, and lack of quality prediction function. To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A welding device for the production of fire-fighting equipment, comprising a base, a plurality of brackets with an annular structure are provided on the base, and a welding machine is provided at the middle position of two adjacent brackets, a gear ring is rotatably provided on the bracket, and a first motor is fixedly provided on the bracket, and a first gear driving the gear ring to rotate is fixedly provided on the rotating shaft of the first motor.

[0007] A ring seat is fixedly installed on the side surface of the gear ring, and screws are rotatably arranged on both lateral sides inside the ring seat. The threads on the screw surface are arranged as opposing threads along the middle, and pipe clamps are arranged on both vertical sides of the inner plate of the ring seat to be driven by the screw to move and fix the pipeline.

[0008] A transverse plate is fixedly provided at the bottom of the lower pipe clamp, and brackets are slidably connected to both ends of the transverse plate. A first spring for resetting the downwardly moved bracket is provided on the transverse plate.

[0009] A groove is provided on the inner side of the lower pipe clamp, and a roller is rotatably arranged in the groove to push the axial displacement of the pipe. A second motor that drives the roller to rotate is fixedly arranged at the bottom of the lower pipe clamp. Two sets of trigger switches are provided between the two brackets and the horizontal plate, and the second motor is started by the trigger switch when the bracket moves downward.

[0010] Preferably, a support seat located on the lower side of the ring seat is fixedly provided on the base, and a connecting rod is slidably connected to the support seat, two cone disks are fixedly provided on the connecting rod, and a push plate is fixedly provided on the bottom of the bracket, and when the push plate moves downward, it pushes the connecting rod to move along the cone disk.

[0011] The support seat is provided with a second spring for pushing the connecting rod to return to its original position.

[0012] Preferably, a second gear and a caliper are rotatably provided on the connecting rod respectively, and when the connecting rod is displaced, the caliper engages with the gear ring to lock it, and when the connecting rod is reset, the second gear enters between the gear ring and the first gear to engage and transmit.

[0013] Preferably, it also includes a wire box placed on the pipe, wherein both sides of the wire box are provided with a pull rope with a hook that is wound by a torsion spring, and a flap is rotatably provided on the top of the wire box, and a notch is opened on the flap for engaging and positioning with the upper pipe clamp.

[0014] Preferably, the two groups of trigger switches drive the second motor to rotate forward and reverse respectively.

[0015] Preferably, a V-shaped guide wheel is provided at the bottom of the push plate, and the guide wheel is tangent to the inclined surface of the cone disk.

[0016] Preferably, the inner wall of the ring seat is provided with a guide groove, and both sides of the pipe clamp are embedded in the guide groove and slide, and the clearance between the guide groove and the pipe clamp is controlled to be 0.1-0.3mm.

[0017] A method for using a welding device for producing fire-fighting equipment comprises the following steps:

[0018] S1. Insert the pipe to be welded into the center of the bracket so that it falls on the lower pipe clamp. When the middle position of the pipe is not aligned with the pipe clamp, the pipe tilts. Different tilt directions squeeze the brackets on different sides to move downward, and the corresponding trigger switch drives the second motor to rotate the roller and push the pipe to move until the pipe is flat and the bracket is released. Then, the pipe clamp is used to clamp the pipe. At this time, the two adjacent pipe ends are aligned, and then welding is performed along the alignment point using the welding machine;

[0019] S2: When the bracket moves downward, the connecting rod is pushed along the cone disk to move, so that the caliper engages with the gear ring to lock the rotation of the pipe clamp. When the pipe adjustment is completed and the bracket is reset, the connecting rod is reset synchronously, so that the second gear is engaged with the first gear and the gear ring. At this time, the first motor can drive the pipe clamp and the pipe to rotate.

[0020] S3. Hook the pull ropes on both sides to the two ends of the pipe through the hooks. At this time, the torsion spring winding structure inside the wire box pulls the wire box to the middle position of the pipe. The operator can use the wire box as a mark to assist in the placement along the pipe clamp. In addition, after the roller adjusts the position of the pipe through gravity distribution, when the flap is turned over, the notch should be aligned with the upper pipe clamp. If it is not aligned, it means that the gravity demarcation point and the length demarcation point of the pipe are not consistent, which also means that the mass distribution of the pipe body is uneven.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] In the present invention, the automatic leveling and positioning system:

[0023] The device adopts a unique gravity-sensing design. When the pipe passes through the bracket, the system can automatically sense its tilt state, trigger the corresponding motor control signal by moving the bracket downward, and drive the roller to make precise position adjustments until the pipe reaches a horizontal state. This process is fully automated and does not require human intervention to ensure the symmetrical distribution of the pipe in the pipe clamp, ensure that the length of the pipe body on both sides of the pipe clamp is evenly distributed, and eliminate welding deviations caused by uneven gravity.

[0024] In the present invention, the intelligent working condition conversion mechanism:

[0025] A sophisticated mechanical interlocking system is installed inside the device. During the pipeline adjustment stage, the caliper mechanism automatically locks the rotation function to prevent external interference. When leveling is completed, the system can automatically unlock and switch to the rotation drive mode. This adaptive conversion design ensures operational stability under various working conditions.

[0026] In the present invention, the quality monitoring function is integrated:

[0027] The innovatively designed junction box positioning system not only provides a construction positioning reference, but also intuitively reflects the uniformity of pipeline quality distribution through the alignment status of the flap notch. When the notch cannot be accurately aligned, it reminds the operator that there may be a problem of uneven pipe density, thus realizing quality prediction during the construction process.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technical personnel in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] See also Figures 1 to 10 The present invention provides a technical solution: a welding device for the production of fire-fighting equipment, comprising a base 1, a plurality of ring-shaped brackets 2 are provided on the base 1, and a welding machine 3 is provided at the middle position of two adjacent brackets 2, a gear ring 4 is rotatably provided on the bracket 2, and a first motor 5 is fixedly provided on the bracket 2, and a first gear 27 for driving the gear ring 4 to rotate is fixedly provided on the rotating shaft of the first motor 5.

[0041] A ring seat 6 is fixedly installed on the side surface of the gear ring 4, and screws 7 are rotatably provided on both sides of the lateral inside of the ring seat 6. The threads on the surface of the screw 7 are set as opposing threads along the center, and pipe clamps 8 are provided on both sides of the vertical inner plate of the ring seat 6, which are driven by the screw 7 to move and fix the pipeline.

[0042] A transverse plate 9 is fixedly provided at the bottom of the lower pipe clamp 8 , and brackets 10 are slidably connected to both ends of the transverse plate 9 . A first spring 11 is provided on the transverse plate 9 for returning the bracket 10 that moves downward.

[0043] A groove 13 is provided on the inner side of the lower pipe clamp 8, and a roller 12 is rotatably provided in the groove 13 to promote the axial displacement of the pipe. A second motor 14 for driving the roller 12 to rotate is fixedly provided at the bottom of the lower pipe clamp 8. Two sets of trigger switches 15 are provided between the two brackets 10 and the horizontal plate 9, and the second motor 14 is started by the trigger switch 15 when the bracket 10 moves downward.

[0044] A support seat 16 located on the lower side of the ring seat 6 is fixedly provided on the base 1, and a connecting rod 17 is slidably connected to the support seat 16. Two cone disks 18 are fixedly provided on the connecting rod 17. A push plate 19 is fixedly provided on the bottom of the bracket 10, and when the push plate 19 moves downward, it pushes the connecting rod 17 to move along the cone disk 18.

[0045] The support seat 16 is provided with a second spring 20 for pushing the connecting rod 17 to return to its original position.

[0046] The second gear 21 and the caliper 22 are rotatably provided on the connecting rod 17. When the connecting rod 17 is displaced, the caliper 22 engages with the gear ring 4 to lock it. When the connecting rod 17 is reset, the second gear 21 enters between the gear ring 4 and the first gear 27 for meshing transmission.

[0047] It also includes a wire box 23 placed on the pipe. Both sides of the wire box 23 are provided with a pull rope 24 with a hook that is wound by a torsion spring, and a flap 25 is rotatably provided on the top of the wire box 23. The flap 25 is provided with a notch 26 for engaging with the upper pipe clamp 8 for positioning.

[0048] The two groups of trigger switches 15 drive the second motor 14 to rotate forward and reverse respectively.

[0049] In this embodiment, Figures 1 to 10 As shown, a V-shaped guide wheel is provided at the bottom of the push plate 19, and the guide wheel is tangent to the inclined surface of the cone disk 18. The V-shaped guide wheel converts sliding friction into rolling friction, thereby improving the pressure transmission efficiency under the push plate 19. The guide wheel and the inclined surface of the cone disk 18 are in line contact mode, which reduces the wear compared to the traditional plane contact.

[0050] In this embodiment, Figures 1 to 10As shown, the inner wall of the ring seat 6 is provided with a guide groove, and the two sides of the pipe clamp 8 are embedded in the guide groove and slide. The clearance between the guide groove and the pipe clamp 8 is controlled at 0.1-0.3mm to ensure that there is no radial shaking during the clamping process. The double guide groove structure makes the force of the pipe clamp 8 symmetrically distributed, and the unilateral deformation is reduced. The guide groove adopts a detachable insert design, and only local parts need to be replaced after wear.

[0051] A method for using a welding device for producing fire-fighting equipment comprises the following steps:

[0052] S1. Pass the pipe to be welded through the center of the bracket 2 so that it falls on the lower pipe clamp 8. When the middle position of the pipe is not aligned with the pipe clamp 8, the pipe tilts. Different tilt directions squeeze the brackets 10 on different sides to move downward, and drive the second motor 14 through the corresponding trigger switch 15 to rotate the roller 12 and push the pipe to move until the pipe is flat and the bracket 10 is released. Then, the pipe clamp 8 is used to clamp the pipe. At this time, the pipe openings of the two adjacent pipes are aligned, and then the welding machine 3 is used to weld along the alignment point. In this way, the pipe in the pipe clamp 8 is automatically adjusted and the pipe body is evenly divided along the pipe clamp 8 to avoid the different lengths of the pipe bodies on both sides of the pipe clamp 8 affecting the pipe alignment welding, and to avoid the different weights on both sides causing the difference in pipe body deformation affecting the welding quality.

[0053] S2. When the bracket 10 moves downward, the connecting rod 17 is pushed along the cone 18 to move, so that the caliper 22 engages with the gear ring 4 to lock the rotation function of the pipe clamp 8. When the pipe adjustment is completed and the bracket 10 is reset, the connecting rod 17 is reset synchronously, so that the second gear 21 intervenes with the first gear 27 and the gear ring 4. At this time, the first motor 5 can drive the pipe clamp 8 and the pipe to rotate, so as to ensure that when the pipe position is not correct, the pipe clamp 8 will not move to affect the adjustment of the pipe, thereby improving the adjustment stability;

[0054] S3. Hang the pull ropes 24 on both sides at the two ends of the pipeline through hooks. At this time, the torsion spring winding structure inside the wire box 23 pulls the wire box 23 to the middle position of the pipeline. The operator uses the wire box 23 as a mark to assist in the placement along the pipe clamp 8. In addition, after the roller 12 adjusts the position of the pipeline through gravity distribution, when the flap 25 is turned over, the notch 26 should be aligned with the upper side pipe clamp 8. If it is not aligned, it means that the gravity demarcation point and the length demarcation point of the pipeline are not the same, which also means that the pipe body mass distribution of the pipeline is uneven, which reminds the operator that there may be a problem of uneven pipe density, thereby realizing quality prediction during the construction process.
