Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, in particular to an assembled large-scale pipeline group clamping platform. Background Art

[0002] The work of cutting pipes and matching pipe fittings according to the requirements of the drawings and then positioning and welding them by welders is called pipe assembly. Pipe assembly requires various equipment to assist workers in processing. For example, when assembling pipes and flanges, the flange needs to be clamped by a clamping platform, and then the pipe is sent to the flange through the assembly slide. After the pipe and flange are aligned, welding operation can be carried out.

[0003] When the existing assembled large-scale pipeline group clamps and welds the flange on the clamping platform, the clamping platform needs to drive the flange to rotate so that the staff or the welding device only needs to aim at one point to weld the entire circular gap. However, in actual operation, the clamping platform needs to first drive the flange to rotate one circle for the staff to weld, and then the clamping platform needs to drive the flange to rotate one circle again for the staff to knock off the welding slag, so as to facilitate subsequent welding and surfacing operations, or to facilitate subsequent grinding operations, and the processing takes a long time. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide an assembled large-scale pipe group clamping platform to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembled large-scale pipeline group clamping platform, comprising a cabin and a first bracket, one side of the first bracket is connected to the second bracket through a torsion spring shaft, and the top of the second bracket is connected to a wheel, electromagnets are installed at the bottom of the first bracket and the second bracket, and a knock rod is passed through the middle of the top of the first bracket and the second bracket, and a spring is sleeved on the outside of the knock rod.

[0006] By adopting the above technical solution, welding work starts at the top of the flange, and as the three-claw chuck drives the flange to rotate, the welding slag rotates to the bottom of the flange. At this time, the electromagnet is opened and closed reciprocatingly. After the electromagnet is started, it generates magnetic attraction to drive the knocking rod downward and compress the spring. After the electromagnet is closed, the spring bounces the knocking rod, causing the knocking rod to hit the welding slag, thereby knocking the welding slag off. The top of the knocking rod is conical, which reduces the contact area with the welding slag and increases the pressure to make the welding slag break and fall off. At the same time, the torsion spring shaft is set to make the second bracket always rotate toward the flange. At this time, the wheel is in contact with the outer circle of the flange for positioning, and friction between the bracket and the rotating flange is avoided to avoid wear, so as to adapt to pipes of different diameters.

[0007] Furthermore, the second bracket is rotatably connected to the first bracket.

[0008] By adopting the above technical solution, the second bracket is always rotated towards the flange through the setting of the torsion spring shaft, and positioning is carried out through the contact between the abutting wheel and the outer circle of the flange. Moreover, the abutting wheel prevents wear caused by friction between the bracket and the rotating flange, so that the knocking rod on the second bracket fits the joint between the flange and the pipeline, facilitating the adaptation to pipelines with different diameters.

[0009] Furthermore, the cross-section of the knocking rod is in the shape of a "tu" character, and the top end of the knocking rod is conical.

[0010] By adopting the above technical solution, the knocking rod with a cross-section in the shape of a "tu" character is convenient for the spring to apply force, the electromagnet to adsorb, and to prevent the knocking rod from falling off the first bracket or the second bracket. Moreover, the top end of the knocking rod is conical, reducing the contact area with the welding slag and thus increasing the pressure, facilitating the breaking and falling off of the welding slag.

[0011] Furthermore, two sets of the second brackets, torsion spring shafts and abutting wheels are provided, and three sets of knocking rods, springs and electromagnets are provided.

[0012] By adopting the above technical solution, if there is a single knocking rod, the knocking rod cannot perform the knocking work when moving downward to compress the spring. However, by setting three sets of knocking rods to perform alternating reciprocating knocking work, dead angles can be avoided.

[0013] Furthermore, the three sets of knocking rods are respectively slidably connected to the first bracket and the two second brackets.

[0014] By adopting the above technical solution, after the electromagnet is activated, it generates magnetic suction to drive the knocking rod to move downward and compress the spring. After the electromagnet is turned off, the spring bounces the knocking rod up, causing the knocking rod to strike the welding slag, thus knocking off the welding slag.

[0015] Furthermore, a scissor lift is installed at the bottom of the cabin, and a three-jaw chuck is installed on the outer surface of the cabin.

[0016] By adopting the above technical solution, the staff opens the three-jaw chuck, then puts the flange into the three-jaw chuck and controls the three-jaw chuck to clamp the flange. At the same time, the staff on the other side places the pipeline on the alignment trolley and pushes the alignment trolley to make the pipeline contact the flange. During this period, the staff can start the scissor lift to adjust the height of the cabin, thereby adjusting the height of the three-jaw chuck and the flange, facilitating the alignment of the flange and the pipeline.

[0017] Furthermore, a motor and a guide rod are respectively arranged at the top of the cabin, the output end of the motor is connected with a screw rod, a sliding table is connected between the screw rod and the guide rod, a hydraulic cylinder is installed on the top of the sliding table, and the first bracket is connected to the output end of the hydraulic cylinder.

[0018] By adopting the above technical solution, the staff turns on the motor and the hydraulic cylinder. After the motor starts, the output end drives the screw to rotate. After the screw rotates, it cooperates with the guidance of the guide rod to move the slide horizontally, so that the knocking rod is located below the joint between the flange and the pipe. After the hydraulic cylinder is started, the knocking rod on the first bracket fits into the joint between the flange and the pipe.

[0019] Furthermore, the slide is threadedly connected to the lead screw, and the slide is slidingly connected to the cabin and the guide rod respectively.

[0020] By adopting the above technical solution, after the motor is started, the output end drives the screw to rotate. After the screw rotates, it cooperates with the guidance of the guide rod to make the slide translate, thereby driving the hydraulic cylinder, the first bracket, the second bracket, the torsion spring shaft, the wheel, the knock rod, the spring and the electromagnet to translate, so that the knock rod is located below the joint between the flange and the pipe.

[0021] In summary, the present invention has the following beneficial effects:

[0022] The utility model starts welding work at the top of the flange through the arrangement of the second bracket, torsion spring shaft, resisting wheel, knocking rod, spring and electromagnet, and as the three-claw chuck drives the flange to rotate, the welding slag is rotated to the bottom of the flange, and the electromagnet is opened and closed reciprocally at this time. After the electromagnet is started, the magnetic attraction is generated to drive the knocking rod to move down and compress the spring. After the electromagnet is closed, the spring bounces the knocking rod, causing the knocking rod to hit the welding slag, thereby knocking the welding slag off, and the top end of the knocking rod is conical, which reduces the contact area with the welding slag and increases the pressure, so as to break and fall off the welding slag; at the same time, the second bracket is always rotated toward the flange through the arrangement of the torsion spring shaft, and is positioned by contacting the outer circle of the flange through the resisting wheel, and avoids friction and wear between the bracket and the rotating flange, so as to adapt to pipes of different diameters; the welding slag is automatically removed, so that the three-claw chuck does not need to be rotated multiple times for the staff to knock off the welding slag, thereby speeding up the assembly efficiency and reducing the labor of workers.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] The following describes an embodiment of the present invention based on its overall structure.

[0030] Example 1:

[0031] A large assembled pipe clamping platform, such as Figure 1-Figure 3 As shown, it includes a cabin 1 and a first bracket 9, one side of the first bracket 9 is connected to a second bracket 10 through a torsion spring shaft 11, the second bracket 10 is rotatably connected to the first bracket 9, and a wheel 12 is connected to the top of the second bracket 10. The second bracket 10, the torsion spring shaft 11 and the wheel 12 are each provided with two groups. The setting of the torsion spring shaft 11 makes the second bracket 10 always rotate toward the flange, and the wheel 12 contacts the outer circle of the flange for positioning, and the wheel 12 avoids friction and wear between the bracket and the rotating flange, so that the knock rod 13 on the second bracket 10 fits the joint between the flange and the pipe, so as to adapt to pipes of different diameters;

[0032] Electromagnets 15 are installed at the bottom of the first bracket 9 and the second bracket 10, and a knocking rod 13 is passed through the middle of the top of the first bracket 9 and the second bracket 10. The cross-section of the knocking rod 13 is in the shape of a "earth" character, and the top of the knocking rod 13 is conical. A spring 14 is sleeved on the outside of the knocking rod 13. There are three groups of knocking rods 13, springs 14 and electromagnets 15. The three groups of knocking rods 13 are slidingly connected to the first bracket 9 and the two groups of second brackets 10 respectively. After the electromagnet 15 is started, it generates magnetic attraction to drive the knocking rod 13 to move downward and compress the spring 14. After the electromagnet 15 is turned off, the spring 14 bounces the knocking rod 13, causing the knocking rod 13 to hit the welding slag, thereby knocking the welding slag off. The top of the knocking rod 13 is conical, which reduces the contact area with the welding slag and increases the pressure, so as to make the welding slag break and fall off.

[0033] See Figure 1 In the above embodiment, a scissor lift platform 2 is installed at the bottom of the cabin 1, and a three-claw chuck 3 is installed on the outer surface of the cabin 1. The staff opens the three-claw chuck 3, then puts the flange into the three-claw chuck 3 and controls the three-claw chuck 3 to clamp the flange.

[0034] Example 2:

[0035] On the basis of the above-mentioned embodiment 1, in order to avoid the knock rod 13 and the joint being misaligned, the following arrangement is adopted.

[0036] See Figure 1 and Figure 3 In the above embodiment, a motor 4 and a guide rod 6 are respectively provided on the top of the cabin 1, and a screw rod 5 is connected to the output end of the motor 4, and a slide 7 is connected between the screw rod 5 and the guide rod 6. The slide 7 is threadedly connected to the screw rod 5, and the slide 7 is slidably connected to the cabin 1 and the guide rod 6 respectively. After the screw rod 5 rotates, the slide 7 is guided by the guide rod 6 to translate, so that the knock rod 13 is located below the joint between the flange and the pipeline; a hydraulic cylinder 8 is installed on the top of the slide 7, and the first bracket 9 is connected to the output end of the hydraulic cylinder 8. After the hydraulic cylinder 8 is started, the knock rod 13 on the first bracket 9 is fitted with the joint between the flange and the pipeline.

[0037] The implementation principle of the utility model is as follows: first, the staff opens the three-claw chuck 3, then the staff puts the flange into the three-claw chuck 3 and controls the three-claw chuck 3 to clamp the flange. At the same time, the staff on the other side places the pipe on the assembly cart and pushes the assembly cart to make the pipe contact with the flange. During this period, the staff can open the scissor lift 2 to adjust the height of the cabin 1, thereby adjusting the height of the three-claw chuck 3 and the flange, so as to align the flange with the pipe.

[0038] After the flange is installed, the staff turns on the motor 4 and the hydraulic cylinder 8. After the motor 4 is started, the output end drives the screw rod 5 to rotate. After the screw rod 5 rotates, it cooperates with the guide rod 6 to guide the slide 7 to move horizontally, thereby driving the hydraulic cylinder 8, the first bracket 9, the second bracket 10, the torsion spring shaft 11, the wheel 12, the knock rod 13, the spring 14 and the electromagnet 15 to move horizontally, so that the knock rod 13 is located below the joint between the flange and the pipe. After the hydraulic cylinder 8 is started, the output end drives the first bracket 9, the second bracket 10, the torsion spring shaft 11, the wheel 12, the knock rod 13, the spring 14 and the electromagnet 15 to move horizontally, 2. The knock rod 13, spring 14 and electromagnet 15 move upward, so that the knock rod 13 on the first bracket 9 fits in the joint between the flange and the pipe. At the same time, the torsion spring shaft 11 is set to make the second bracket 10 always rotate toward the flange, and the wheel 12 contacts the outer circle of the flange for positioning. The wheel 12 prevents friction and wear between the bracket and the rotating flange, so that the knock rod 13 on the second bracket 10 fits in the joint between the flange and the pipe, so as to adapt to pipes of different diameters.

[0039] After the docking work is completed, the staff starts welding work on the top of the flange by manual welding or using a welding machine. As the three-claw chuck 3 drives the flange to rotate, the welding slag rotates to the bottom of the flange. At this time, the staff opens and closes the electromagnet 15 reciprocatingly. After the electromagnet 15 is started, it generates a magnetic attraction to drive the knocking rod 13 to move down and compress the spring 14. After the electromagnet 15 is turned off, the spring 14 bounces the knocking rod 13, causing the knocking rod 13 to hit the welding slag, thereby knocking the welding slag off. The top of the knocking rod 13 is conical, which reduces the contact area with the welding slag and increases the pressure to make the welding slag break and fall off.
