Description

Technical Field

[0001] The present application relates to the technical field of construction and civil engineering, and in particular to a positioning tooling system for an automated welding production line for a segment main reinforcement assembly. Background Art

[0002] The segment reinforcement skeleton refers to the steel structure embedded in the segment concrete to enhance the structural strength and stability of the segment when manufacturing the segment (a prefabricated component used in tunnels, pipelines and other projects). This reinforcement skeleton is usually composed of multiple steel bars combined in a specific design and layout to form an integral support structure. During the production process of the segment, the reinforcement skeleton is prefabricated and placed in a mold, and then concrete is poured. After the concrete solidifies, a segment with a reinforcement skeleton is formed. This structure can effectively improve the bearing capacity, crack resistance and durability of the segment.

[0003] Reference Figure 1 , Figure 2 In the prior art, the segment reinforcement skeleton mainly includes outer arc main reinforcement 82, inner arc main reinforcement 81, connecting reinforcement 83, stirrups, hand hole spiral reinforcement, angle reinforcement and other auxiliary reinforcements, wherein the connecting reinforcement 83 is installed between the inner arc main reinforcement 81 and the outer arc main reinforcement 82, and multiple connecting reinforcements 83 are arranged at intervals along the curvature of the inner arc main reinforcement 81. The inner arc main reinforcement 81, the outer arc main reinforcement 82 and multiple connecting reinforcements 83 are combined to form a main reinforcement assembly 8, and the multiple main reinforcement assemblies 8 are connected in series through auxiliary reinforcements such as stirrups to form a segment reinforcement skeleton.

[0004] However, this type of segment steel skeleton relies too much on manual labor during preparation, and needs to be manually tied and fixed one by one on the membrane frame, which is a time-consuming and labor-intensive process. In particular, when preparing the main reinforcement assembly, since both the outer arc main reinforcement and the inner arc main reinforcement are long arc-shaped structures, when welding the outer arc main reinforcement and the inner arc main reinforcement, the manual method makes it easy for the outer arc main reinforcement and the inner arc main reinforcement to align when they are aligned (the main reason for the deviation is that the virtual center line of the outer arc main reinforcement does not coincide with the virtual center line of the inner arc main reinforcement, or the inner and outer arc main reinforcements are deformed, etc.), which makes it difficult to weld the connecting reinforcement between the outer arc main reinforcement and the inner arc main reinforcement, and the welding effect is poor, which reduces the overall forming quality of the segment steel skeleton. Summary of the invention

[0005] In order to improve the positioning accuracy between the outer arc main reinforcement and the inner arc main reinforcement, the present application provides a positioning tooling system for an automated welding production line for a segment main reinforcement assembly.

[0006] The positioning tooling system of the automatic welding production line for the main reinforcement assembly of the pipe segment provided in this application adopts the following technical solutions: The positioning tooling system of the automatic welding production line of the main reinforcement assembly of the pipe segment includes a mounting support, a rotating platform and a positioning mechanism. The rotating platform is rotatably connected to the mounting support, and the positioning mechanism is arranged on the rotating platform; the positioning mechanism includes an inner arc limit block, an inner arc limit plate, an outer arc limit block and an outer arc limit plate. The inner arc limit block and the outer arc limit block are both arranged on the rotating platform and are arranged in multiple intervals around the central axis of the rotating platform. The inner arc limit plate and the outer arc limit plate are both slidably arranged on the rotating platform. The number of arc limit plates and inner arc limit blocks, and the number of outer arc limit plates and outer arc limit blocks are set correspondingly, an inner arc track for clamping the inner arc main reinforcement is formed between the multiple inner arc limit blocks and the multiple inner arc limit plates, and an outer arc track for clamping the outer arc main reinforcement is formed between the multiple outer arc limit blocks and the multiple outer arc limit plates, and the inner arc track and the outer arc track are coaxially arranged; the mounting support is provided with a driving assembly, and the driving assembly is used to drive the inner arc limit plates and the outer arc limit plates to displace so as to clamp and fix the inner arc main reinforcement or the outer arc main reinforcement.

[0007] By adopting the above-mentioned technical scheme, through the arrangement of inner arc limit blocks, inner arc limit plates, outer arc limit blocks and outer arc limit plates, an inner arc track is formed between multiple inner arc limit blocks and multiple inner arc limit plates, and an outer arc track is formed between multiple outer arc limit blocks and multiple outer arc limit plates. When preparing the main reinforcement assembly, the inner arc main reinforcement is placed on the inner arc track, and the outer arc main reinforcement is placed on the outer arc track. The inner arc limit plates and the outer arc limit plates are driven to move by the driving component, so that the inner arc limit blocks and the inner arc limit plates can be clamped together on the inner arc main reinforcement, and the outer arc limit blocks and the outer arc limit plates can be clamped together on the outer arc main reinforcement, thereby clamping and fixing the inner arc main reinforcement and the outer arc main reinforcement, so that the inner arc main reinforcement and the outer arc main reinforcement can quickly maintain coaxiality, thereby improving the positioning accuracy between the outer arc main reinforcement and the inner arc main reinforcement. In addition, taking the inner arc main reinforcement as an example, if the inner arc main reinforcement is deformed, the combination of multiple inner arc limit blocks and multiple inner arc limit plates can clamp and fix the inner arc main reinforcement, thereby correcting the deformed inner arc main reinforcement and restoring its curvature, thereby facilitating the installation of connecting reinforcement between the inner arc main reinforcement and the outer arc main reinforcement.

[0008] Optionally, the driving assembly includes a first cylinder, a second cylinder and a third cylinder, the cylinder body of the first cylinder is arranged on a mounting support, and the piston rod of the first cylinder is connected to an inner arc limit plate to drive the inner arc limit plate to approach or move away from a corresponding inner arc limit block; the second cylinder is arranged on a mounting support, and the piston rod of the second cylinder is connected to a lifting plate, the cylinder body of the third cylinder is arranged on the lifting plate, and the piston rod of the third cylinder is connected to an outer arc limit plate to drive the outer arc limit plate to approach or move away from a corresponding outer arc limit block, and the rotating platform is provided with an avoidance groove for lifting and lowering the third cylinder.

[0009] By adopting the above-mentioned technical scheme, through the arrangement of the first cylinder, the second cylinder and the third cylinder, after the inner arc main reinforcement is placed on the inner arc track and the outer arc main reinforcement is placed on the outer arc track, the piston rod of the first cylinder is driven to push outward, forcing the inner arc limit plate to move toward the inner arc limit block, shrinking the inner arc track, so that the inner arc limit block and the inner arc limit plate are jointly clamped on the inner arc main reinforcement; at the same time, the third cylinder is lifted by the second cylinder, so that the outer arc limit plate passes through the avoidance groove and is lifted to the same plane as the outer arc limit block, and then the piston rod of the third cylinder is driven to push outward, forcing the outer arc limit plate to move toward the outer arc limit block, shrinking the outer arc track, so that the outer arc limit block and the outer arc limit plate are jointly clamped on the outer arc main reinforcement, thereby improving the convenience of positioning between the inner arc main reinforcement and the outer arc main reinforcement.

[0010] Optionally, the driving assembly includes a first cylinder, a connecting strip and a return spring, the cylinder body of the first cylinder is arranged on a mounting support, the piston rod of the first cylinder is directed toward the inner arc limit plate to push the inner arc limit plate close to the corresponding inner arc limit block; the connecting strip is slidably connected to the rotating platform, the inner arc limit plate and the outer arc limit plate are both connected to the connecting strip, the return spring is arranged between the connecting strip and the rotating platform, and the return spring normally causes the connecting strip to move toward the side close to the first cylinder to expand the inner arc path or the outer arc path.

[0011] By adopting the above-mentioned technical scheme, through the arrangement of the first cylinder, the connecting strip and the return spring, the connecting strip is connected in series with the inner arc limit plate and the outer arc limit plate, so that the inner arc limit plate and the outer arc limit plate are connected as a whole; when the inner arc main rib is placed on the inner arc track and the outer arc main rib is placed on the outer arc track, when the piston rod of the first cylinder is driven to push outward, the inner arc limit plate and the outer arc limit plate move synchronously, thereby simultaneously reducing the inner arc track and the outer arc track, and then clamping and fixing the inner arc main rib and the outer arc main rib at the same time, thereby improving the operational convenience of the overall structure and reducing the manufacturing cost.

[0012] Optionally, the number of the inner arc limit blocks and the outer arc limit blocks are set correspondingly, a movable groove is opened on the surface of the rotating platform, and the outer arc limit block is slidably installed in the movable groove; the rotating platform is provided with an adjustment component, and the adjustment component is used to drive the outer arc limit block to move closer to or away from the corresponding inner arc limit block.

[0013] By adopting the above-mentioned technical scheme and adjusting the setting of the components, when it is necessary to control the spacing between the inner arc main reinforcement and the outer arc main reinforcement (different thicknesses of segments require segment steel bar skeletons of different thicknesses), the adjusting components are used to force the outer arc limit block to move along the moving groove, so that the outer arc limit block is close to or away from the corresponding inner arc limit block, thereby adjusting the spacing between the inner arc main reinforcement and the outer arc main reinforcement, so as to be able to prepare segment steel bar skeletons of different thicknesses, thereby improving the adaptability of the overall structure.

[0014] Optionally, the rotary platform has a positioning area, the positioning area is located between the inner arc main reinforcement and the outer arc main reinforcement, and a positioning component for positioning the connecting reinforcement is provided in the positioning area.

[0015] By adopting the above-mentioned technical solution and setting the positioning component, the positioning component is used to position the connecting ribs, so that after the inner arc main ribs and the outer arc main ribs are clamped and fixed, the two ends of the connecting ribs can respectively connect with the inner arc main ribs and the outer arc main ribs, thereby facilitating the subsequent welding process.

[0016] Optionally, the positioning assembly includes two clamping plates, which are elastically arranged, and one side of the two clamping plates is connected to the surface of the rotating platform, and a clamping channel for clamping the connecting ribs is formed between the two clamping plates. Each clamping plate is provided with a folding plate on the side away from the rotating platform, and a guide channel connecting the clamping channels is formed between the two folding plates, and the guide channel gradually decreases in size from the end away from the clamping channel to the end close to the clamping channel.

[0017] By adopting the above-mentioned technical scheme, through the setting of the clamping piece, the clamping piece is elastically set. When the connecting rib is installed, the connecting rib is aligned with the guide channel and pushed, so that the connecting rib squeezes the two clamping pieces and enters the clamping channel. The elastic restoring force of the two clamping pieces can clamp and fix the connecting rib, so that the connecting rib can be fixed in the set position for connecting the inner arc main rib and the outer arc main rib.

[0018] Optionally, a positioning seat is provided in the positioning area, and the positioning assembly includes a positioning block, a positioning rod, an abutment spring and a linkage member, the positioning block is slidably installed on the positioning seat so as to be able to rise and fall, and two positioning rods are provided, the two positioning rods are hinged to the positioning seat and are symmetrically distributed on both sides of the positioning block, both sides of the positioning block have a first guide surface, the two first guide surfaces are arranged corresponding to the two positioning rods, the two ends of the abutment spring are respectively connected to the two positioning rods, and the abutment spring normally makes one end of the two positioning rods abut against the first guide surface corresponding to the positioning block, when the positioning block is lifted and abuts against the peripheral wall of the connecting rib, the positioning block pushes the two positioning rods to rotate, and the ends of the two positioning rods away from the abutment springs abut against the peripheral wall of the connecting rib; the linkage member is arranged between the positioning block and the connecting strip, and when the connecting strip is displaced toward the side away from the first cylinder, the linkage member forces the positioning block to lift.

[0019] By adopting the above-mentioned technical solution, through the setting of the positioning block, the positioning rod, the abutment spring and the linkage part, the first cylinder drives the connecting bar to move to clamp and fix the inner arc main rib and the outer arc main rib. Under the action of the linkage part, the positioning block can be lifted and drive the two positioning rods to swing under the action of the first guide surface, so that the positioning block and the two positioning rods can abut against the surrounding wall of the connecting rib, thereby positioning the connecting rib.

[0020] Optionally, the linkage part includes a pushing block, a pushing frame and a lifting bar, the pushing block is connected to the upper surface of the connecting bar, the pushing frame is slidably installed on the rotating platform, and the positioning block is connected to the pushing frame; one end of the lifting bar is connected to the pushing frame, and the bottom of the lifting bar has a second guide surface for the pushing block to abut against, and when the connecting bar is displaced toward the side away from the first cylinder, the pushing block forces the lifting bar to lift through the second guide surface.

[0021] By adopting the above technical solution, through the arrangement of the pushing block, the pushing frame and the lifting bar, the pushing block is driven to move during the movement of the connecting bar. The pushing block pushes the lifting bar to lift a certain distance through the second guide surface, thereby driving the positioning block to lift a certain distance, so that the positioning block and the two positioning rods can be clamped together on the connecting rib, thereby improving the convenience of positioning the connecting rib.

[0022] Optionally, a thickening plate is detachably installed between the pushing block and the connecting bar, a connecting piece is provided between the pushing block and the connecting bar, and the pushing block is detachably installed on the connecting bar via the connecting piece.

[0023] By adopting the above-mentioned technical solution and setting a thickening sheet between the push block and the connecting bar, the lifting distance of the lifting bar can be changed, thereby changing the lifting distance of the positioning block. According to the actual requirements of the lifting distance of the positioning block, different numbers of thickening sheets are selected to be installed, so that the positioning block and the two positioning rods can be used to clamp connecting ribs of different diameters, thereby greatly improving the applicability of the overall structure.

[0024] Optionally, a first roller is rotatably mounted on the top wall of the positioning block, and second rollers are rotatably mounted on the ends of the two positioning rods away from the positioning block, and the first roller and the two second rollers are both in contact with the peripheral wall of the connecting rib and can roll along the length direction of the connecting rib; when the first roller and the two second rollers are both in contact with the peripheral wall of the connecting rib, the first roller and the two second rollers are arranged in a triangle around the central axis of the connecting rib.

[0025] By adopting the above technical scheme, through the setting of the first roller and the two second rollers, the first roller and the two second rollers are arranged in a triangle around the central axis of the connecting rib, thereby improving the clamping effect of the connecting rib; when the first cylinder drives the connecting bar to move and clamps and fixes the inner arc main rib and the outer arc main rib, due to the change in the positions of the inner arc main rib and the outer arc main rib, a certain thrust or pull can be applied to the connecting rib to make it adaptively displaced along its own axial direction; the setting of the first roller and the two second rollers can reduce the friction resistance of the connecting rib during displacement, thereby improving the smoothness of the displacement of the connecting rib along its own axial direction.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the arrangement of inner arc limit blocks, inner arc limit plates, outer arc limit blocks and outer arc limit plates, an inner arc track is formed between multiple inner arc limit blocks and multiple inner arc limit plates, and an outer arc track is formed between multiple outer arc limit blocks and multiple outer arc limit plates. When preparing the main reinforcement assembly, the inner arc main reinforcement is placed on the inner arc track, and the outer arc main reinforcement is placed on the outer arc track. The inner arc limit plates and the outer arc limit plates are driven to move by the driving component, so that the inner arc limit blocks and the inner arc limit plates can be clamped together on the inner arc main reinforcement, and the outer arc limit blocks and the outer arc limit plates can be clamped together on the outer arc main reinforcement, thereby clamping and fixing the inner arc main reinforcement and the outer arc main reinforcement, so that the inner arc main reinforcement and the outer arc main reinforcement can quickly maintain coaxiality, thereby improving the positioning accuracy between the outer arc main reinforcement and the inner arc main reinforcement. In addition, taking the inner arc main reinforcement as an example, if the inner arc main reinforcement is deformed, the combination of multiple inner arc limit blocks and multiple inner arc limit plates can clamp and fix the inner arc main reinforcement, so as to correct the deformed inner arc main reinforcement and restore its curvature, thereby facilitating the installation of the connecting reinforcement between the inner arc main reinforcement and the outer arc main reinforcement; 2. Through the arrangement of the positioning block, the positioning rod, the abutment spring and the linkage member, when the first cylinder drives the connecting bar to move so as to clamp and fix the inner arc main rib and the outer arc main rib, the positioning block can be lifted under the action of the linkage member, and the two positioning rods are driven to swing under the action of the first guide surface, so that the positioning block and the two positioning rods can abut against the peripheral wall of the connecting rib, thereby positioning the connecting rib; 3. Through the arrangement of the pushing block, the pushing frame and the lifting bar, the pushing block is driven to move during the movement of the connecting bar. The pushing block pushes the lifting bar to lift a certain distance through the second guide surface, thereby driving the positioning block to lift a certain distance, so that the positioning block and the two positioning rods can be clamped together on the connecting rib, thereby improving the convenience of positioning the connecting rib.

[0049] Embodiment 4: The embodiment of the present application discloses a positioning tooling system for an automated welding production line for a segment main reinforcement assembly.

[0050] Reference Fig.11 The positioning tooling system for the automatic welding production line of the segment main reinforcement assembly disclosed in the embodiment of the present application is different from that in embodiment 2 in that: In this embodiment, the upper surface of the rotating platform 2 is provided with a plurality of positioning grooves 29 located in the positioning area 23, each positioning groove 29 passes through the lower surface of the rotating platform 2, and each positioning groove 29 is installed with a positioning seat 7, and a second connecting bolt 71 is installed between the positioning seat 7 and the rotating platform 2, and the rotating platform 2 is provided with a third connecting hole, and the side wall of the positioning seat 7 is provided with a plurality of fourth connecting holes, and the plurality of fourth connecting holes are arranged at intervals along the height direction, and the second connecting bolt 71 passes through the third connecting hole and the fourth connecting hole in sequence and is threadedly connected to the fourth connecting hole, and the positioning seat 7 is detachably installed on the rotating platform 2 through the second connecting bolt 71.

The positioning assembly 6 includes a positioning block 62, a positioning rod 63, an abutment spring 64 and a linkage member. The positioning block 62 is slidably installed on the positioning seat 7 and can be lifted and lowered. The top wall of the positioning block 62 is rotatably installed with a first roller 622 for abutting against the peripheral wall of the linkage rib 83; there are two positioning rods 63, both of which are hinged to the positioning seat 7, and the two positioning rods 63 are symmetrically distributed on both sides of the positioning block 62. The end of each positioning rod 63 close to the positioning block 62 is rotatably installed with a third roller 632, and both sides of the positioning block 62 have a first guide surface 621, and the two first guide surfaces 621 are correspondingly arranged with the two positioning rods 63. The first guide surface 621 is used for the third roller 632 of the corresponding positioning rod 63 to abut.

[0052] Reference Fig.11 , the two ends of the abutment spring 64 are respectively connected to the two positioning rods 63, and the abutment spring 64 normally makes the third rollers 632 of the two positioning rods 63 abut against the first guide surface 621 corresponding to the positioning block 62; the ends of the two positioning rods 63 away from the positioning block 62 are rotatably installed with the second roller 631 for abutting the peripheral wall of the connecting rib 83. When the positioning block 62 is lifted and the first roller 622 abuts against the peripheral wall of the connecting rib 83, the positioning block 62 pushes the two positioning rods 63 to rotate, and the second rollers 631 of the two positioning rods 63 abut against the peripheral wall of the connecting rib 83. When the first roller 622 and the two second rollers 631 abut against the peripheral wall of the connecting rib 83, the first roller 622 and the two second rollers 631 are arranged in a triangle around the central axis of the connecting rib 83, and can roll along the length direction of the connecting rib 83.

[0053] Reference Fig.11 , Fig.12 , Fig.13 The linkage member is arranged between the positioning block 62 and the connecting strip 44. When the connecting strip 44 moves toward the side away from the first cylinder 41 to clamp the inner arc main rib 81 and the outer arc main rib 82, the linkage member forces the positioning block 62 to lift so that the positioning block 62 and the two positioning rods 63 clamp the connecting rib 83.

The pushing frame 66 is slidably installed on the bottom of the rotating platform 2. The pushing frame 66 is respectively connected with a first pushing rod 661 and a second pushing rod 662. One end of the first pushing rod 661 is fixedly connected to the pushing frame 66, and the other end is fixedly connected to the lifting bar 67.

The bottom of the lifting bar 67 has a second guide surface 671, and the second guide surface 671 is used for the pushing block 65 to abut. When the connecting bar 44 moves toward the side away from the first cylinder 41, the pushing block 65 forces the lifting bar 67 to lift through the second guide surface 671.

[0055] The implementation principle of Example 4 of the present application is as follows: the first cylinder 41 drives the connecting bar 44 to move, and when the inner arc main rib 81 and the outer arc main rib 82 are clamped and fixed, the connecting bar 44 can drive the positioning block 62 to lift through the lifting bar 67, so that the positioning block 62 and the two positioning rods 63 clamp and fix the connecting rib 83, so that the clamping and fixing of the inner arc main rib 81, the outer arc main rib 82 and the connecting rib 83 are carried out synchronously, thereby improving the operational convenience of the overall structure and facilitating subsequent welding operations. In addition, after welding is completed, the piston rod of the first cylinder 41 is driven back, and the clamping effect of the inner arc main rib 81, the outer arc main rib 82 and the connecting piece can be released at the same time, thereby facilitating the disassembly of the main rib assembly 8 after forming, greatly improving the overall work efficiency.

According to the actual requirements of the lifting distance of the positioning block 62, different numbers of thickening sheets 651 are selected to be installed, so that the positioning block 62 and the two positioning rods 63 can be used to clamp connecting ribs 83 of different diameters, thereby greatly improving the applicability of the overall structure.
