DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0023] In the description of the present application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery" and the like indicate the orientation or positional relationship, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the indicated component or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.
[0024] The following is based on Figure 1 Figure 18 The present application provides a culvert steel bar welding device and its working method.
[0025] In one aspect, the present application provides a culvert steel bar welding device.
[0026] Embodiment one, please refer to Figure 1 Figure 2 This invention provides a culvert reinforcement welding device, including a longitudinal reinforcement tie plate 3, a longitudinal reinforcement fixing plate, a welding robot 1 and a winding and unwinding mechanism 2 located between the longitudinal reinforcement tie plate 3 and the longitudinal reinforcement fixing plate. A dividing plate 10 is also provided on the side of the longitudinal reinforcement fixing plate away from the longitudinal reinforcement tie plate 3. A track 11 is laid on the ground for the longitudinal reinforcement tie plate 3 to move. The longitudinal reinforcement is first divided by the dividing plate 10, then passes through the longitudinal reinforcement fixing plate, and then fixed on the longitudinal reinforcement tie plate 3. The winding is wound around the circular structure formed by the longitudinal reinforcement. A rotating mechanism is provided on the longitudinal reinforcement tie plate 3 to drive the entire circular structure formed by the longitudinal reinforcement to rotate, so that the longitudinal reinforcement moves and rotates at the same time, and the winding can be wound around the circular structure formed by the longitudinal reinforcement. The welding robot 1 is used to weld the intersection of the longitudinal reinforcement and the winding to form a cage-like culvert reinforcement.
[0027] Combination Figure 3 - Figure 6 As shown, to ensure welding accuracy, the longitudinal rib plate here includes a fixing frame 4, which contains a perforated plate 5. The perforated plate 5 includes a plate body and a support ring 52. The dividing plate 10 is connected to the plate body by a connecting shaft 7. The plate body is composed of multiple concentric carrier rings 51 (e.g., Figure 5 A gap 57 is formed between two adjacent carrier rings 51, and the two adjacent carrier rings 51 are connected by a connecting part 55 arranged radially. Preferably, the connecting part 55 is integrally formed with the carrier ring 51, and a second blind groove 54 is provided on the inner wall of the carrier ring 51.
[0028] The number of support rings 52 is equal to the gap 57. The support rings 52 are located within the gap 57 and can move axially within the gap 57, so that the side of the support ring 52 closest to the welding robot 1 protrudes from the carrier ring 51. The area on the outer surface of the support ring 52 opposite to the second blind groove 54 is provided with a first blind groove 53. The first blind groove 53 and the second blind groove 54 form a longitudinal rib through hole, through which the longitudinal rib can pass directly.
[0029] It should be noted that when the support ring 52 protrudes from the side of the carrier ring 51 near the welding robot 1, it is in an extended state, so that when the welding robot 1 is welding the intersection of the longitudinal rib and the winding rib, the intersection can be supported by the support ring 52, thereby ensuring its welding stability.
[0030] In addition, since the embodiments of the present invention have multiple sets of longitudinal reinforcement holes, they can be adapted to cage-type culvert reinforcement of different diameters. The larger the diameter of the reinforcement cage, the more longitudinal reinforcement it has, which matches the actual situation. Furthermore, each diameter of cage-type culvert reinforcement can be supported by the corresponding support ring 52 during welding, thus ensuring welding accuracy.
[0031] Furthermore, since the first blind groove 53 is directly set on the support ring 52, after the support ring 52 extends, the first blind groove 53 on it can actually limit the axial displacement of the longitudinal rib, further ensuring the stability of the welding.
[0032] Preferably, a through slot 56 is formed on the support ring 52, which can be matched with the connecting part 55, and the through slot 56 can guide the connecting part 55 when the support ring 52 moves axially, so as to ensure that the support ring 52 extends and retracts linearly.
[0033] In addition, the positions of the connecting part 55 and the through slot 56 avoid the longitudinal rib perforation.
[0034] The application also comprises a driving mechanism, which is located at one end of the support ring 52 and is used to push a required support ring 52 to protrude from the carrier ring 51. An installation disc 6 is installed on the side of the fixed frame 4 away from the longitudinal rib pull plate 3. Essentially, each support ring 52 has an independent driving mechanism, which comprises a first screw rod 87 and a driving body. The first screw rod 87 is rotatably installed between the carrier ring 51 and the installation disc 6. A nut 86 is threadedly connected to the first screw rod 87, and the nut 86 is integrated with the support ring 52. The driving body is installed on the installation disc 6 and is used to drive the first screw rod 87 on the same carrier ring 51 to rotate.
[0035] In the embodiment, when the driving body works, the first screw rod 87 can rotate and drive the first screw rod 87 to rotate. When the first screw rod 87 rotates, the support ring 52 can be driven to move by the nut 86, thereby achieving the purpose of extending the support ring 52.
[0036] Preferably, the carrier ring 51 and the installation disc 6 are fixedly connected through a pull rod 12, and the carrier ring 51 and the installation disc 6 are rotatably installed in the fixed frame 4 through bearing rings.
[0037] In the embodiment, as shown in Figure 4 , Figure 5 , Figure 7 Each support ring 52 is provided with three groups of first screw rods 87, and the three first screw rods 87 are uniformly arranged in the circumferential direction.
[0038] As shown in Figure 7 , in order to realize that the driving body can synchronously control the rotation of the three first screw rods 87, the driving body comprises an inner tooth ring 81, a limiting seat 83 and a driving gear 82. The limiting seat 83 is fixed on the side of the installation disc 6 away from the hole disc 5. The inner tooth ring 81 is rotatably supported on the limiting seat 83. The driving gear 82 is fixed on the first screw rod 87, and the driving gear 82 is engaged with the inner tooth ring 81.
[0039] In the embodiment, the staff manually pushes the inner tooth ring 81 to rotate, thereby driving the driving gear 82 to rotate, and the driving gear 82 can drive the first screw rod 87 to rotate when it rotates.
[0040] In use (working time), 1) push out the required diameter of the support ring 52, select the required diameter of the support ring 52 according to the required diameter of the reinforcement cage, rotate the required inner tooth ring 81 by manual pushing, thereby driving the driving gear 82 to rotate, which can drive the lead screw 87 to rotate, and then the nut 86 can drive the support ring 52 to move, realizing the purpose of pushing out the support ring 52; 2) Assemble longitudinal reinforcement and winding reinforcement, divide the reinforcement through the dividing disc 10, then pass through the installation disc 6 and longitudinal reinforcement perforation, and then fix it on the longitudinal reinforcement pull plate 3 (the fixing method is the bolt tightening in the prior art), and wind the winding reinforcement on the longitudinal reinforcement; 3) Start the welding operation, the longitudinal reinforcement pull plate 3 drives the longitudinal reinforcement to move and rotate at the same time, the winding reinforcement can be wound on the longitudinal reinforcement when the longitudinal reinforcement rotates, and the welding manipulator 1 welds the intersection of the longitudinal reinforcement and the winding reinforcement under the support of the support ring 52.
[0041] Embodiment two, refer to Figure 8 - Figure 14 as shown.
[0042] In production, the greater the length of the support ring 52 made, the greater the support range of the reinforcement cage, the smaller the settlement tensile stress of the welding point close to the longitudinal reinforcement pull plate 3 side, and the better the welding strength. However, in fact, the axial length of the support ring 52 cannot be set too large, because if it is set too large, it will cause the rotation load of the entire carrier ring 51 to be too large.
[0043] If you want the carrier ring 51 to support a large range, the length of the lead screw 87 needs to meet the displacement of the longer carrier ring 51, so that the axial length of the entire longitudinal reinforcement plate is larger, the displacement of the support ring 52 is larger, and it will also cause the rotation load of the entire carrier ring 51 to be too large.
[0044] In order to solve this problem, the embodiment adds an acceleration assembly for driving the end ring 521 based on the structure of embodiment one, which mainly consists of an acceleration moving structure 85 and an acceleration gear set one 84 as Figure 10 and Figure 11 The side of the support ring 52 close to the welding manipulator 1 is provided with an end ring 521, and the first blind groove 53 is also arranged on the end ring 521. The acceleration assembly can control the greater extension length of the end ring 521 without increasing the axial length of the longitudinal reinforcement plate, thereby supporting the reinforcement cage in a larger range, and reducing the case that the welding point stress is too large due to the settlement of the welding point close to the longitudinal reinforcement pull plate 3 side during welding.
[0045] Specifically, refer to Figure 10 - Figure 13As shown, the aforementioned acceleration assembly includes an acceleration movement structure 85 and an acceleration gear set 84. The acceleration movement structure 85 includes: an internally threaded cylinder 851 fixedly disposed on the inner wall of the end ring 521, the end ring 521 and the internally threaded cylinder 851 being integral, one end of the internally threaded cylinder 851 extending to the end of the carrier ring 51 near the mounting plate 6, and the internally threaded cylinder 851 being axially slidably disposed on the inner wall of the opposing carrier ring 51, the internal thread of the internally threaded cylinder 851 being threadedly connected to a second lead screw 853, which, when the second lead screw 853 rotates, can cause the internally threaded cylinder 851 to generate axial displacement, thereby achieving the purpose of the end ring 521 generating axial displacement in the carrier ring 51. In order to enable the second lead screw 853 to move together with the carrier ring 51 and to rotate to control the acceleration displacement of the end ring 521, the end of the second lead screw 853 away from the end ring 521 is rotatably connected to the support ring 52 through a bearing seat 852, so that the carrier ring 51 can drive the second lead screw 853 to move synchronously.
[0046] A drive shaft 854 is inserted inside the lead screw 853. The drive body is also used to control the rotation of the drive shaft 854. The internal gear ring 81 controls the rotation speed of the drive shaft 854 to be greater than the rotation speed of the lead screw 87 through the acceleration gear set 84.
[0047] In this embodiment, when the internal gear ring 81 rotates, in addition to controlling the rotation of the lead screw 87 by the drive gear 82 to push out the carrier ring 51, the drive shaft 854 can also be accelerated to rotate by the acceleration gear set 84. The accelerated rotation of the drive shaft 854 can drive the lead screw 853 to accelerate and push the end ring 521, thereby achieving its large-range support.
[0048] Preferably, the drive shaft 854 has a polygonal structure, so that it can be circumferentially limited within the lead screw 853 to drive the lead screw 853 to rotate. As the lead screw 853 moves with the support ring 52, the area overlapping with the drive shaft 854 gradually decreases.
[0049] Furthermore, the drive shaft 854 has a cylindrical structure in the area where it intersects with the mounting plate 6, and this cylindrical structure is mounted on the mounting plate 6 by bearings.
[0050] Preferred, such as Figure 14 and Figure 15 As shown, the aforementioned acceleration gear set 84 includes a second drive gear 841, which meshes with the inner wall of the internal gear ring 81. One end of the second drive gear 841 is provided with a diameter-increasing gear 842 coaxial with it. The central shafts of the second drive gear 841 and the diameter-increasing gear 842 are rotatably mounted on the mounting plate 6. One side of the diameter-increasing gear 842 is meshed with an acceleration gear 843, and the central shaft of the acceleration gear 843 is also rotatably mounted on the mounting plate 6. One end of the drive shaft 854 is fixedly provided with a main gear 844, which meshes with the acceleration gear 843.
[0051] In this embodiment, when the inner tooth ring 81 rotates, it can drive the driving gear two 841 to rotate, and then the increasing diameter gear one 842 can drive the accelerating gear one 843 to accelerate rotation, and the accelerating gear one 843 can drive the main gear one 844 to rotate, and the main gear one 844 can drive the driving shaft 854 to rotate.
[0052] In use (at work), the difference from example one is that 1) the step of pushing out the support ring 52 of the required diameter, according to the diameter of the required reinforcement cage, the required diameter of the support ring 52 is selected, the required inner tooth ring 81 is manually pushed to rotate, thereby driving the driving gear one 82 to rotate, which can drive the lead screw one 87 to rotate, and then the nut one 86 can drive the support ring 52 to move, achieving the purpose of pushing out the support ring 52, in the process of pushing out the support ring 52, the carrier ring 51 can drive the lead screw two 853 to move synchronously, at the same time, when the inner tooth ring 81 rotates, it can also drive the driving shaft 854 to accelerate rotation through the accelerating gear set one 84, and the accelerating rotation of the driving shaft 854 can drive the lead screw two 853 to accelerate the pushing of the end ring 521, so that the moving length of the end ring 521 is greater than that of the support ring 52, and the welding point is still supported by the support ring 52, but the end ring 521 plays the role of large-scale support, reducing the situation that the welding point stress is too large due to the settlement of the welding point close to one side of the longitudinal reinforcement and the plate 3 during welding.
[0053] Example three, this example is an alternative to the driving mechanism in the above-mentioned example one, referring to Figure 15 - Figure 18 as shown.

[0057] Preferably, the handle 96 is installed on the side of the rotating ring 95 close to the longitudinal bar pull plate 3, and the handle groove 13 is formed on the surface of the carrier ring 51 close to the longitudinal bar pull plate 3 for the handle 96 to slide.
[0058] In use, the difference from the first embodiment is that 1) the step of pushing out the support ring 52 with the required diameter, in this embodiment, specifically: according to the diameter of the required reinforcement cage, select the support ring 52 with the required diameter, rotate the rotating ring 95 by manually pushing the handle 96, the protrusion 94 can push the rotating gear 91 to rotate through the spiral groove, and when the rotating gear 91 rotates, the rack plate one 92 can push the support ring 52, so that the support ring 52 is pushed out.

[0061] Specifically, the above-mentioned acceleration gear set two 93 includes a diameter increasing gear two 931, the diameter increasing gear two 931 rotates synchronously with the rotating gear 91, one side of the diameter increasing gear two 931 is engaged with an acceleration gear two 932, one end of the acceleration gear two 932 is provided with a diameter increasing gear three 933 coaxial with it, and the diameter increasing gear three 933 is engaged with the rack plate two 98.

[0063] It should be noted that all the gears in the acceleration gear set two 93 are rotatably installed in the interlayer of the carrier ring 51.
[0064] In use, the difference from example three is that 1) the step of pushing out the support ring 52 of the required diameter, in this embodiment, the diameter of the support ring 52 required is selected according to the diameter of the reinforcement cage required, the rotation of the rotating ring 95 is realized by manually pushing the handle 96, the convex 94 can push the rotating gear 91 to rotate through the spiral groove, and when the rotating gear 91 rotates, the support ring 52 can be pushed out through the rack plate one 92, and in the process of rotating the rotating gear 91, it can also simultaneously drive the diameter increasing gear two 931 to rotate, the diameter increasing gear two 931 drives the acceleration gear two 932 to accelerate rotation, and moves the rack plate two 98 through the diameter increasing gear three 933, thereby realizing the accelerated movement of the end ring 521, realizing that the movement length of the end ring 521 is greater than the movement length of the support ring 52, the welding point is still supported by the support ring 52, but the end ring 521 plays the purpose of large-scale support, reducing the case that the welding point stress is too large due to the settlement of the welding point close to the side of the longitudinal reinforcement tie plate 3.
[0065] On the other hand, the application also provides a working method of a culvert steel bar welding device, comprising the following steps: Step one, selecting the corresponding longitudinal reinforcement perforation according to the diameter of the reinforcement cage, and passing the longitudinal reinforcement through the longitudinal reinforcement perforation; Step two, pushing out the support ring 52 of the selected longitudinal reinforcement perforation relative to the support ring 52, so that the support ring 52 can radially support the longitudinal reinforcement and circumferentially limit the longitudinal reinforcement during welding by the welding manipulator 1.
