Description

Technical Field

[0001] This invention belongs to the field of transfer fixture technology, and particularly relates to a synchronous transfer fixture system for welding arc-shaped steel cages. Background Technology

[0002] The segment reinforcement cage is a key structural component used in the fabrication of reinforced concrete segments and plays an important role in fields such as tunnel lining.

[0003] Currently, during the welding of tunnel segment reinforcement cages, the reinforcing bars are first conveyed to the bending station for arc bending. Then, the bent main reinforcement bars are conveyed to the welding station via a material transfer mechanism. During welding, the stirrups and main reinforcement bars are fitted together, and welding robots on the inner and outer sides weld them together. After welding, the material conveying mechanism transports the reinforcement cage for final assembly. However, existing devices mostly use chain lifting or roller support, resulting in line or point contact between the arc-shaped reinforcement cage and the conveying surface. This leads to insufficient friction and uneven force distribution, making it impossible to effectively transport the reinforcement cage. Summary of the Invention

[0004] The purpose of this invention is to address the current problem in tunnel segment rebar cage welding: First, the rebar needs to be transferred to a bending station for arc bending. Then, a material transfer mechanism transfers the bent main rebar to the welding station. During welding, the stirrups and main rebar are joined together, and welding is performed by welding robots on the inner and outer sides. After welding, the material transfer mechanism transports the rebar cage for final assembly. However, existing devices often use chain lifting or roller support, resulting in line or point contact between the arc-shaped rebar cage and the transfer surface. This leads to insufficient friction and uneven force distribution, making effective transfer of the rebar cage impossible. Therefore, this invention proposes a synchronous transfer clamping system for arc-shaped rebar cage welding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a synchronous transfer clamp system for welding arc-shaped steel cages, comprising:

[0006] The support frame has a connecting frame at its top, an upper annular plate connected to the connecting frame, a drive motor at the top of the upper annular plate, a connecting shaft on the drive motor, a drive gear sleeved on the connecting shaft, and a guide rail at the bottom of the upper annular plate.

[0007] The movable ring plate has a rack on its top and guide wheels on both sides. The drive gear and the rack mesh with each other, and the guide wheels roll on the guide rail.

[0008] And several transfer clamps, which are connected to the bottom of the moving ring plate.

[0009] Furthermore, a lower annular plate is provided at the bottom of the aforementioned upper annular plate, and a positioning element is provided on the lower annular plate.

[0010] Furthermore, the aforementioned positioning component includes a support plate, a first telescopic cylinder, and a positioning seat. The first telescopic cylinder passes through the support plate and is connected to the positioning seat. The guide shaft is movably connected to the support plate, and the top of the guide shaft is connected to the positioning seat. The positioning seat includes an axial positioning plate and a transverse positioning plate, with the transverse positioning plate connected to the bottom of the axial positioning plate.

[0011] Furthermore, a limiting platform is provided on the aforementioned guide rail, and the guide wheel component includes a connecting plate, a first guide wheel, and a second guide wheel. The second guide wheel is rotatably connected to the movable ring plate, the connecting plate is connected to the movable ring plate, the first guide wheel is rotatably connected to the connecting plate via a rotating shaft, the first guide wheel rolls on the limiting platform, and the second guide wheel rolls on the bottom of the limiting platform.

[0012] Furthermore, the first guide wheel and the second guide wheel are arranged perpendicularly.

[0013] Furthermore, the aforementioned transfer fixture includes a fixed plate, a second telescopic cylinder, several connecting arms, and a gripping hook. The fixed plate is connected to the movable ring plate, the second telescopic cylinder is connected to the fixed plate, several connecting arms are located on both sides of the second telescopic cylinder, a drive joint is provided at the bottom of the second telescopic cylinder, the drive joint is located inside the connecting arm, and a first limiting shaft is provided on the gripping hook, the first limiting shaft is connected to the connecting arm and the drive joint.

[0014] Furthermore, the cross-section of the aforementioned connecting frame is cross-shaped, and several reinforcing rods are provided on the connecting frame.

[0015] Furthermore, the connecting arm is provided with two interconnected oblong holes, and a bending hole is provided at the connection of the two oblong holes. A second limiting shaft is provided at the top of the gripping hook, the second limiting shaft is located in the top oblong hole, and the first limiting shaft is located in the bending hole.

[0016] This invention provides a synchronous transfer clamping system for welding arc-shaped rebar cages. The entire welding system is connected via a ring frame with multiple workstations: a conveying mechanism, a welding mechanism, a material gripping mechanism, and a transport mechanism. A movable ring plate is located at the bottom of the upper ring plate, and a transfer clamp is positioned at the bottom of the movable ring plate. When the welded rebar cage needs to be transferred, the drive motor drives the drive gear to rotate, thereby moving the movable ring plate and placing the transfer clamp above the rebar cage. A second telescopic cylinder extends and retracts, causing the drive joint to rotate, which in turn moves the material gripping hook outward and engages with the stirrups of the rebar cage. The first telescopic cylinder in the bottom positioning component descends, causing the bottom of the rebar cage to disengage from the positioning seat. The drive motor then continues to start, driving the movable ring plate to move to the material conveying structure, completing the material conveying process. This structure integrates material transfer, welding, material shifting, and material transport, improving the production efficiency of rebar cages.

[0017] Therefore, this embodiment has the following advantages compared to the prior art:

[0018] A synchronous transfer clamping system for welding arc-shaped steel cages solves the problem that in current tunnel segment steel cage welding, the steel bars must first be transferred to the bending station for arc bending, and then the main curved bars are transferred to the welding station via a material transfer mechanism. During welding, the stirrups and main bars are in contact and welded by welding robots on the inner and outer sides. After welding, the material transfer mechanism transports the steel cage to complete the assembly. However, existing devices mostly use chain lifting or roller support, and the contact between the arc-shaped steel cage and the transfer surface is line contact or point contact, resulting in insufficient friction and uneven force, which makes it impossible to effectively transfer the steel cage.
