Description

Technical Field

[0001] This invention relates to the field of steel cage processing technology, and in particular to a bending device and bending method. Background Technology

[0002] During tunnel construction, after the tunnel boring machine (TBM) excavates a circular hole, multiple arc-shaped tunnel segments are needed to secure the hole, providing a robust and safe operating space for subsequent work. TBM segments are formed by combining the shield's steel reinforcement cage with concrete anchorage.

[0003] The existing shield tunnel steel reinforcement cage consists of multiple arc-shaped single-piece meshes and multiple stirrups. The multiple single-piece meshes are arranged alternately and parallel to each other, and the multiple stirrups are arranged alternately and parallel to each other and welded and fixed to the outer periphery of the multiple single-piece meshes. After the multiple single-piece meshes are fixed, they form an arc-shaped shield tunnel steel reinforcement cage.

[0004] In existing technologies, the steel reinforcement cage for tunnel boring machines is manufactured manually using welding jigs. Equipment such as steel bar shearing production lines, bending machines, and other tools are used to cut, bend, and twist the main reinforcement bars, as well as to fabricate tie bars and stirrups. Finally, the bars are manually placed onto the welding jigs and welded to complete the steel reinforcement cage. This processing method is cumbersome, requires a large workforce, has low production efficiency, and the welding conditions are harsh, making it difficult to guarantee operator safety. Specifically, the bending of the stirrup ends is poorly automated, complex, time-consuming, and labor-intensive, and the quality of the stirrup binding cannot be guaranteed. Summary of the Invention

[0005] The purpose of this invention is to provide a bending device and bending method that can conveniently and efficiently bend the head and tail of stirrups.

[0028] Preferably, the first drive mechanism includes a first drive cylinder, a second drive cylinder, and a third drive cylinder connected in series.

[0029] When the first drive cylinder extends and the second and third drive cylinders retract, the locking frame and the bending frame are located outside the outer arc rib.

[0078] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0079] like Figures 1-13As shown, the present invention provides a bending device, including a support base 1, a movable frame 2, a first driving mechanism 3, a locking frame 4, a second driving mechanism 5, a bending frame 6, and a third driving mechanism 7. The movable frame 2 is slidably mounted on the support base 1 along the first direction. The first drive mechanism 3 is mounted on the support base 1 and configured to drive the movable frame 2 to translate. The locking frame 4 is rotatably connected to the movable frame 2 around the second direction. The locking frame 4 is provided with a locking port 411. The second direction is perpendicular to the first direction. The second drive mechanism 5 is mounted on the movable frame 2 and configured to drive the locking frame 4 to rotate. The bending frame 6 is rotatably connected to the locking frame 4 around the second direction. The bending frame 6 is provided with a first bend 61 and a second bend 62. When the locking port 411 locks the outer arc rib 101 of the single mesh 100, the first bend 61 can bend the protruding part of the stirrup 200 outside the single mesh 100 inside the outer arc rib 101. The second bend 62 can bend the protruding part of the stirrup 200 outside the outer arc rib 101. The third drive mechanism 7 is mounted on the locking frame 4 and configured to drive the bending frame 6 to rotate.

[0080] In this invention, the first driving mechanism 3 can drive the moving frame 2 to translate relative to the support base 1 to move closer to or further away from the single mesh 100. The second driving mechanism 5 can drive the locking frame 4 to rotate relative to the moving frame 2 so that the locking port 411 on the locking frame 4 is engaged with the outer arc rib 101. Based on the locking port 411 engaging with the outer arc rib 101, the third driving mechanism 7 drives the bending frame 6 to rotate relative to the locking mechanism, so that the first bend 61 and the second bend 62 can bend the protruding parts of the stirrups 200 on the inner and outer sides of the outer arc rib 101 respectively. This is simple and reliable, and realizes convenient and efficient bending of the head and tail of the stirrups 200, ensuring the binding quality of the stirrups 200.

[0081] Specifically, the support base 1 includes two guide rails 11 and a fixing block 12. The two guide rails 11 are parallel and spaced apart. The movable frame 2 is slidably mounted on the two guide rails 11. The locking frame 4 and the bending frame 6 are located between the two guide rails 11. The fixing block 12 is mounted on the two guide rails 11, and the first drive mechanism 3 is mounted on the fixing block 12. By using two guide rails 11, the translation of the movable frame 2 is made more stable. By using the fixing block 12, the force applied by the first drive mechanism 3 is made more balanced.

[0082] More specifically, the movable frame 2 includes a main body 21, side supports 22, and movable wheels 23. The output end of the first drive mechanism 3 is connected to the main body 21, and the second drive mechanism 5 is mounted on the main body 21. Two side supports 22 are provided, parallel to each other and spaced apart, and are respectively connected to the main body 21. Two guide rails 11 are located between the two side supports 22. A locking frame 4 is rotatably mounted between the two side supports 22. Movable wheels 23 are respectively provided on the facing sides of the two side supports 22, and guide grooves are respectively provided on the opposing sides of the two guide rails 11, with the movable wheels 23 rolling within the guide grooves. The movable frame 2 is positioned to enclose the outside of the two guide rails 11 and is connected to the guide rails 11 via the movable wheels 23, further ensuring the smooth and reliable movement of the movable frame 2.

[0083] In this embodiment, the guide groove on the guide rail 11 is provided through the first direction, and each side support 22 is provided with two moving wheels 23.

[0084] Specifically, the locking frame 4 includes a first piece 41 and a second piece 42. A locking port 411 is disposed on the first piece 41, a bending frame 6 is rotatably mounted between the first piece 41 and the second piece 42, the first piece 41 and the second piece 42 are rotatably connected to two side supports 22, and a second drive mechanism 5 is rotatably mounted on the main body 21, with its output end rotatably connected to the first piece 41 and the second piece 42.

[0085] More specifically, the first bend 61 and the second bend 62 are spaced apart in the second direction. Since the stirrups 200 are tied around the periphery of multiple single meshes 100 and their ends are staggered and both fit against the outer arc reinforcement 101, staggering the first bend 61 and the second bend 62 is more suitable for bending the ends of the stirrups 200.

[0086] In this embodiment, the bending device also includes an arc-shaped moving platform 8. The support base 1 is adjustablely mounted on the arc-shaped moving platform 8 and can be positioned along the extension direction of the arc-shaped moving platform 8. The arc-shaped moving platform 8 is located outside the bottom layer of the single mesh 100 of the steel cage to be formed and is adapted to the bending degree of the outer arc reinforcement 101, so that the bending device can perform bending operations on multiple stirrups 200 respectively. Each stirrup 200 on the steel cage to be formed is provided with a threaded mounting hole on the arc-shaped moving platform 8. The support base 1 is fixedly mounted on the arc-shaped moving platform 8 by fasteners screwed into the mounting holes.

[0087] Specifically, the two side walls of the locking opening 411 are a first locking wall 412 and a second locking wall 413, respectively. When the first locking wall 412 abuts against the outer side of the outer arc rib 101, the first elbow 61 can bend the protruding part of the stirrup 200 inside the outer arc rib 101. When the second locking wall 413 abuts against the inner side of the outer arc rib 101, the second elbow 62 can bend the protruding part of the stirrup 200 outside the outer arc rib 101. By setting the first locking wall 412 and the second locking wall 413 to abut and lock the protruding parts of the stirrup 200 on the outer and inner sides of the outer arc rib 101, respectively, the locking effect is better, and the displacement or deformation of the outer arc rib 101 is avoided when the stirrup 200 is bent.

[0088] In this embodiment, the locking opening 411 is provided through the second direction, and the first locking wall 412 and the second locking wall 413 are provided at intervals in the first direction. They are arc-shaped surfaces, and the two arc-shaped surfaces protrude in opposite directions. Therefore, when they abut against the outer arc rib 101, in addition to limiting the outer arc rib 101 in the first direction, they can also limit the outer arc rib 101 in the third direction. The first direction, the second direction and the third direction are perpendicular to each other.

[0089] More specifically, the first drive mechanism 3 includes a first drive cylinder 31, a second drive cylinder 32, and a third drive cylinder 33 connected in series. During the bending operation, when the first drive cylinder 31 extends and the second drive cylinder 32 and the third drive cylinder 33 retract, the locking frame 4 and the bending frame 6 are located outside the outer arc rib 101; when the first drive cylinder 31 and the second drive cylinder 32 extend and the third drive cylinder 33 retract, the outer arc rib 101 can extend into the locking port 411; when the first drive cylinder 31, the second drive cylinder 32, and the third drive cylinder 33 extend, the first locking wall 412 can abut against the outside of the outer arc rib 101; when the second drive cylinder 32 extends and the first drive cylinder 31 and the third drive cylinder 33 retract, the second locking wall 413 can abut against the inside of the outer arc rib 101. By setting three drive cylinders, the first locking wall 412 and the second locking wall 413 abut against and lock the inner and outer sides of the outer arc rib 101 simply and efficiently.

[0090] In this embodiment, the first drive cylinder 31 is mounted on the fixing block 12 of the support base 1, the second drive cylinder 32 is mounted on the piston rod of the first drive cylinder 31, and the third drive cylinder 33 is mounted on the piston rod of the second drive cylinder 32. The piston rod of the third drive cylinder 33 is connected to the main body 21 of the movable frame 2, and the extendable length of the piston rod of the second drive cylinder 32 is greater than the extendable length of the piston rod of the first drive cylinder 31, and also greater than the extendable length of the piston rod of the third drive cylinder 33.

[0091] More specifically, the second drive mechanism 5 includes a fourth drive cylinder 51, which, when extended, drives the locking port 411 to move upward. By driving the locking frame 4 and the bending frame 6 to swing up and down, the outer arc rib 101 can be hooked and locked from the lower side of the single mesh 100 in a convenient and reliable manner.

[0092] In this embodiment, the fourth drive cylinder 51 is rotatably mounted on the main body 21, and the piston rod of the fourth drive cylinder 51 is rotatably connected to the first plate 41 and the second plate 42. During the extension of the fourth drive cylinder 51, the locking port 411 gradually rises. When the piston rod of the fourth drive cylinder 51 is fully extended, the locking frame 4 is in a horizontal state.

[0093] Specifically, the third drive mechanism 7 includes a fifth drive cylinder 71 and a sixth drive cylinder 72 connected in series. During the bending operation, when the fifth drive cylinder 71 and the sixth drive cylinder 72 extend, they can drive the first elbow 61 to bend the protruding part of the stirrup 200 inside the outer arc rib 101. When the fifth drive cylinder 71 and the sixth drive cylinder 72 retract, they can drive the second elbow 62 to bend the protruding part of the stirrup 200 outside the outer arc rib 101. The two drive cylinders cooperate to simply and efficiently drive the second elbow 62 and the first elbow 61 to complete the bending action against the stirrup 200.

[0094] More specifically, the fifth drive cylinder 71 is mounted on the locking frame 4, the piston rod of the fifth drive cylinder 71 is connected to the sixth drive cylinder 72, the piston rod of the sixth drive cylinder 72 is rotatably connected to one end of the transmission rod, and the other end of the transmission rod is rotatably connected to the bending frame 6.

[0095] In this embodiment, the first drive cylinder 31, the second drive cylinder 32, the third drive cylinder 33, the fourth drive cylinder 51, the fifth drive cylinder 71, and the sixth drive cylinder 72 are pneumatic cylinders or hydraulic cylinders. Their specific structures and working principles are existing technologies and will not be described in detail here. The extension of the drive cylinder is the extension of its piston rod to its maximum extent, and the retraction of the drive cylinder is the retraction of its piston rod to its maximum extent. In other embodiments, the first drive mechanism 3, the second drive mechanism 5, and the third drive mechanism 7 may also include any number of other drive cylinders, as long as the bending operation of the stirrup 200 can be achieved. Furthermore, the connection method of the drive cylinders in the first drive mechanism 3, the second drive mechanism 5, and the third drive mechanism 7 can be, in addition to the cylinder body being connected to the piston rod, the cylinder body being connected to the cylinder body and the piston rod being connected to the piston rod.

[0096] This embodiment also provides a bending method using the above-described bending device, comprising the following steps:

[0097] S1. The support seat 1 moves to the position of a stirrup 200, and the first drive mechanism 3 and the second drive mechanism 5 drive the locking frame 4 and the bending frame 6 to extend into the lower side of the single mesh 100.

[0098] S2. The second driving mechanism 5 drives the locking frame 4 to rotate, so that the outer arc rib 101 extends into the locking port 411.

[0099] S3. The third driving mechanism 7 drives the bending frame 6 to rotate, so that the first bend 61 bends the extension of the stirrup 200 inside the outer arc rib 101, and the second bend 62 bends the extension of the stirrup 200 outside the outer arc rib 101.

[0100] S4. The second drive mechanism 5 drives the locking frame 4 to rotate, causing the outer arc rib 101 to disengage from the locking port 411.

[0101] S5, the support seat 1 moves along the arc-shaped moving platform 8 to the position of the next stirrup 200.

[0102] In this embodiment of the bending method, the first driving mechanism 3 can drive the moving frame 2 to translate relative to the support base 1 to move closer to or away from the single mesh 100. The second driving mechanism 5 can drive the locking frame 4 to rotate relative to the moving frame 2 so that the locking port 411 on the locking frame 4 is engaged with the outer arc rib 101. Based on the locking port 411 engaging the outer arc rib 101, the third driving mechanism 7 drives the bending frame 6 to rotate relative to the locking port 411, so that the first bend 61 and the second bend 62 can bend the protruding parts of the stirrups 200 on the inner and outer sides of the outer arc rib 101 respectively. This method is simple and reliable, and achieves convenient and efficient bending of the head and tail of the stirrups 200, ensuring the binding quality of the stirrups 200.

[0103] The bending method of this embodiment will be described in detail below, specifically including the following steps:

[0104] Step 1: In the first drive mechanism 3, only the first drive cylinder 31 extends, the fourth drive cylinder 51 retracts, the locking frame 4 drives the bending frame 6 to tilt downwards, and in the third drive mechanism 7, only the fifth drive cylinder 71 extends.

[0105] In this step, such as Figure 5 As shown, the locking frame 4 drives the bending frame 6 to tilt downwards, and the whole is located outside the bottom layer of the single mesh 100 of the steel cage to be formed.

[0106] Step 2: In the first drive mechanism 3, only the first drive cylinder 31 and the second drive cylinder 32 extend out, driving the locking frame 4 and the bending frame 6 to extend into the lower side of the single-piece net 100.

[0107] In this step, such as Figure 6 As shown, the first driving mechanism 3 drives the locking frame 4 and the bending frame 6 to translate toward the monolithic mesh 100 until the locking opening 411 is located below the outer arc rib 101 of the monolithic mesh 100.

[0108] Step 3: The fourth drive cylinder 51 extends, and the locking frame 4 is raised to a horizontal position, so that the outer arc rib 101 extends into the locking port 411.

[0109] In this step, such as Figure 7 and Figure 8 As shown, the outer arc rib 101 is initially housed in the locking opening 411, and is spaced apart from both the first locking wall 412 and the second locking wall 413.

[0110] Step 4: The first drive cylinder 31, the second drive cylinder 32 and the third drive cylinder 33 in the first drive mechanism 3 all extend out, and the first locking wall 412 of the locking port 411 abuts against the outer side wall of the outer arc rib 101.

[0111] In this step, such as Figure 9 As shown, the first driving mechanism 3 drives the locking frame 4 to translate a maximum distance until the first locking wall 412 of the locking port 411 abuts against the outer wall of the outer arc rib 101.

[0112] Step 5: In the third drive mechanism 7, both the fifth drive cylinder 71 and the sixth drive cylinder 72 extend, the bending frame 6 rotates relative to the locking frame 4, and the first bend 61 abuts against the protruding part of the bend 200 inside the outer arc rib 101.

[0113] In this step, such as Figure 9 As shown, the first elbow 61, which is opposite to the first locking wall 412, rotates under the drive of the third driving mechanism 7, bending the stirrup 200.

[0114] Step 6: In the third drive mechanism 7, only the fifth drive cylinder 71 extends, and the bending frame 6 returns to the horizontal state.

[0115] In this step, the bending frame 6 is reset under the drive of the third drive mechanism 7.

[0116] Step 7: In the first drive mechanism 3, only the first drive cylinder 31 and the second drive cylinder 32 extend out, and the outer arc rib 101 is located in the locking port 411 without interference.

[0117] In this step, the locking port 411 is translated under the drive of the first drive mechanism 3.

[0118] Step 8: In the first drive mechanism 3, only the second drive cylinder 32 extends out, and the second locking wall 413 of the locking port 411 abuts against the inner side wall of the outer arc rib 101.

[0119] In this step, such as Figure 10 As shown, the second locking wall 413 functions by abutting against the inner wall of the outer arc rib 101.

[0120] Step 9: In the third drive mechanism 7, both the fifth drive cylinder 71 and the sixth drive cylinder 72 retract, the bending frame 6 rotates relative to the locking frame 4, and the second bend 62 abuts against the protruding part of the bend rib 200 outside the outer arc rib 101.

[0121] In this step, such as Figure 10 As shown, the second elbow 62, which is opposite to the second locking wall 413, rotates under the drive of the third driving mechanism 7, bending the stirrup 200.

[0122] Step 10: In the third drive mechanism 7, only the fifth drive cylinder 71 extends, and the bending frame 6 returns to the horizontal state.

[0123] In this step, the bending frame 6 is reset under the drive of the third drive mechanism 7.

[0124] Step 11: In the first drive mechanism 3, only the first drive cylinder 31 and the second drive cylinder 32 extend out, and the outer arc rib 101 is located in the locking port 411 without interference.

[0125] In this step, the locking port 411 is translated under the drive of the first drive mechanism 3.

[0126] Step 12: The fourth drive cylinder 51 retracts, and the locking frame 4 causes the bending frame 6 to tilt downward.

[0127] In this step, the locking port 411 descends under the drive of the fourth drive cylinder 51.

[0128] Step 13: In the first drive mechanism 3, only the first drive cylinder 31 extends, driving the locking frame 4 and the bending frame 6 away from the lower side of the single-piece net 100.

[0129] In this step, the drive locking frame 4 and bending frame 6 are moved away from the monolithic mesh 100.

[0130] Step 14: The support seat 1 moves along the arc-shaped moving platform 8 to the position of the next stirrup 200.

[0131] Then proceed with steps one through thirteen in sequence to bend the next stirrup 200 of the steel cage to be formed.
