Description

Technical Field

[0001] This utility model relates to the field of precast box girder steel reinforcement cage technology, and in particular to an assembly device. Background Technology

[0002] The precast box girder reinforcement cage is assembled from a bottom slab reinforcement mesh, two web reinforcement meshes, and a top slab reinforcement mesh. During fabrication, the bottom slab reinforcement mesh, two web reinforcement meshes, and top slab reinforcement mesh are fabricated separately. After these are completed, the bottom slab reinforcement mesh is placed at the bottom, the two web reinforcement meshes are assembled at the left and right ends of the bottom slab reinforcement mesh, and the top slab reinforcement mesh is assembled on top of the two web reinforcement meshes. The overlapping sections are then fixed to form the precast box girder reinforcement cage.

[0003] In existing technology, an assembly device is designed to assemble the bottom slab reinforcement mesh and the two web reinforcement meshes. The assembly device includes a bottom slab platform and two tilting frames. The two tilting frames are independently positioned relative to the bottom slab platform, located on either side of the platform. The bottom slab platform supports the bottom slab reinforcement mesh, and the two tilting frames each support one of the two web reinforcement meshes. During assembly, the two tilting frames rotate the two web reinforcement meshes, assembling them at both ends of the bottom slab reinforcement mesh. However, the two tilting frames are driven by their own separate drive mechanisms, and the rotation cannot be guaranteed to be coordinated and symmetrical. This results in the two web reinforcement meshes not being symmetrically positioned relative to the bottom slab reinforcement mesh, affecting the assembly quality of the precast box girder reinforcement skeleton. Utility Model Content

[0004] The purpose of this invention is to provide an assembly device that can drive two web steel meshes to rotate synchronously relative to the bottom steel mesh.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Assembly device, including:

[0007] A base plate platform, wherein the base plate platform is provided with a base plate bearing surface that supports the base plate steel mesh;

[0008] Two web platforms are respectively rotatably connected to both ends of the base plate platform in the first direction, and the web platforms are provided with web bearing surfaces that bear the web steel mesh;

[0009] The driving mechanism includes a driver, two active modules, and two driven modules. The two active modules are mounted on the output end of the driver. The driver can drive the two active modules to move towards or away from each other along the first direction. The two driven modules are fixedly connected to the two web platforms in a one-to-one correspondence. The driven modules are provided with transmission teeth, and the two transmission teeth mesh with the two active modules in a one-to-one correspondence. When the driver drives the two active modules to move, it can drive the two web platforms to rotate synchronously towards or away from each other through the two driven modules.

[0010] Preferably, the driver includes a dual-axis compound cylinder, and the two active modules are connected one-to-one to the two output ends of the dual-axis compound cylinder.

[0011] Preferably, the driver includes a motor and a drive gear, the drive gear is mounted on the output end of the motor, and the drive module includes a drive rack that extends along the first direction, with two drive racks facing each other and meshing with opposite sides of the drive gear.

[0012] Preferably, the active module includes:

[0013] An active module is connected to the output terminal of the driver;

[0014] The drive chain is fixed to the drive mold base and meshes with the transmission teeth.

[0015] Preferably, the active module further includes an adjusting rod, which is tunably connected to the active mold base along the first direction. One end of the active chain is fixed to the active mold base, and the other end is fixed to the adjusting rod.

[0016] Preferably, the active mold base is provided with a receiving groove, and the active chain is laid at the bottom of the receiving groove.

[0017] Preferably, the active module is slidably connected to the base plate platform along the first direction.

[0018] Preferably, the active module includes a sliding wheel, and the active module is capable of moving along the first direction via the sliding wheel.

[0019] Preferably, the transmission tooth profile extends in an arc shape;

[0020] When one end of the transmission tooth is engaged with the active module, the web platform is in a load-bearing state. When the web platform is in the load-bearing state, the web bearing surface is parallel to the bottom plate bearing surface.

[0021] When the other end of the transmission tooth meshes with the active module, the web platform is in the assembled state. When the web platform is in the assembled state, the web bearing surface and the bottom plate bearing surface are set at an angle.

[0022] Preferably, the system also includes a support base, with each web platform having one support base. When the web platform abuts against the support base, it is in a load-bearing state. When the web platform is in the load-bearing state, the bottom plate bearing surface is parallel to the web bearing surface.

[0023] The beneficial effects of this utility model are:

[0024] The web platform is rotatably connected to the base plate platform, enabling it to rotate based on the base plate platform. This is more precise and reliable. In the drive mechanism, the driver can drive two active modules to move synchronously towards or away from each other, thereby driving two driven modules meshing with the active modules to rotate precisely and reliably synchronously. Ultimately, the two driven modules drive the two web platforms to rotate synchronously towards or away from each other, ensuring the coordinated and symmetrical rotation of the two web platforms. This allows the two web steel meshes to be symmetrically set relative to the base plate steel mesh during assembly, enabling the assembly of the base plate steel mesh and the two web steel meshes, and ensuring the assembly quality of the precast box girder steel skeleton.

[0038] Example 1

[0039] like Figures 1-2As shown, this embodiment provides an assembly device, including a base platform 1, a web platform 2, and a drive mechanism 3. The base platform 1 has a base bearing surface for supporting the base plate steel mesh 100. Two web platforms 2 are provided, rotatably connected to both ends of the base platform 1 in a first direction. Each web platform 2 has a web bearing surface for supporting the web plate steel mesh 200. The drive mechanism 3 includes a driver 31, two active modules 32, and two driven modules 33. The two active modules 32 are mounted on the output end of the driver 31, which drives the two active modules 32 to move towards or away from each other along the first direction. The two driven modules 33 are fixedly connected to the two web platforms 2 in a one-to-one correspondence. Each driven module 33 has a transmission tooth 331, which meshes with the two active modules 32 in a one-to-one correspondence. When the driver 31 drives the two active modules 32, the two driven modules 33 can drive the two web platforms 2 to rotate synchronously towards or away from each other.

[0040] In this invention, the web platform 2 is rotatably connected to the base platform 1, enabling it to flip based on the base platform 1, which is more precise and reliable. In the drive mechanism 3, the driver 31 can drive the two active modules 32 to move synchronously towards or away from each other, thereby driving the two driven modules 33 meshing with the active modules 32 to rotate precisely and reliably synchronously. Finally, the two driven modules 33 drive the two web platforms 2 to flip synchronously towards or away from each other, ensuring the coordinated and symmetrical flipping action of the two web platforms 2. This allows the two web steel meshes 200 to be symmetrically set relative to the base plate steel mesh 100 during assembly, realizing the assembly operation of the base plate steel mesh 100 and the two web steel meshes 200, and ensuring the assembly quality of the precast box girder steel skeleton.

[0041] Specifically, the actuator 31 includes a dual-axis compound cylinder, and two active modules 32 are connected one-to-one to the two output ends of the dual-axis compound cylinder. This arrangement enables the actuator 31 to safely and efficiently drive the two active modules 32 to move synchronously.

[0042] In this embodiment, the cylinder body of the dual-axis compound cylinder is fixedly installed on the base plate platform 1, and the two piston rods serve as two output ends, extending in opposite directions along the first horizontal direction and respectively connected to the two active modules 32.

[0043] Specifically, the active module 32 includes an active module 321 and an active chain 322. The active module 321 is connected to the output end of the driver 31, and the active chain 322 is fixed to the active module 321 and meshes with the transmission tooth profile 331. By setting the active module 321, the active chain 322 can drive the transmission tooth profile 331 to rotate forward and backward, and the chain structure is low in cost and easy to maintain and replace.

[0044] More specifically, the active module 32 also includes an adjusting rod 323, which is adjustablely connected to the active mold base 321 along a first direction. One end of the active chain 322 is fixedly connected to the active mold base 321, and the other end is fixedly connected to the adjusting rod 323. This arrangement allows for adjustment of the tension of the active chain 322, thereby making the meshing between the active chain 322 and the transmission tooth profile 331 safer and more reliable.

[0045] More specifically, the active mold base 321 is provided with a receiving groove 3211, and the active chain 322 is laid at the bottom of the receiving groove 3211. The above arrangement avoids interference between the active chain 322 and external foreign objects.

[0046] In this embodiment, the active mold base 321 is provided with a through hole, and the adjusting rod 323 is slidably inserted into the through hole. Two nuts are screwed onto it, and the two nuts are located on both sides of the through hole. By adjusting the position of the two nuts, the position of the adjusting rod 323 on the active mold base 321 can be adjusted. The base plate platform 1 and the active mold base 321 are both placed on the bearing plane. Under the drive of the driver 31, the two active mold bases 321 can move closer to the base plate platform 1 or move away from the base plate platform 1 simultaneously.

[0047] In another embodiment, the active module 32 is slidably connected to the base platform 1 along a first direction. This configuration makes the movement of the active module 32 relative to the base platform 1 more precise and reliable.

[0048] In the above embodiment, a dressing channel is provided on the base plate platform 1, and the active mold base 321 is slidably disposed in the dressing channel.

[0049] In another embodiment, the active module 32 includes a sliding wheel, which enables the active module 32 to move along a first direction. By providing the sliding wheel, the movement of the active module 32 becomes more stable while allowing it to move more independently.

[0050] In the above embodiment, the sliding wheel is disposed at the bottom of the active mold base 321, and the active mold base 321 moves by means of the sliding wheel under the drive of the driver 31.

[0051] Specifically, the transmission tooth profile 331 extends in an arc shape. When one end of the transmission tooth profile 331 meshes with the drive module 32, the web platform 2 is in a load-bearing state. When the web platform 2 is in a load-bearing state, the web bearing surface is parallel to the bottom plate bearing surface. When the other end of the transmission tooth profile 331 meshes with the drive module 32, the web platform 2 is in an assembly state. When the web platform 2 is in the assembly state, the web bearing surface and the bottom plate bearing surface are set at an angle. At this time, the web bearing surface and the bottom plate bearing surface assemble the web steel mesh 200 and the bottom plate steel mesh 100 they each bear together. The above configuration enables the transmission tooth profile 331 to accurately and reliably drive the web platform 2 to move between the load-bearing state and the assembly state.

[0052] More specifically, the assembly device also includes a support base 4, with each web platform 2 equipped with a support base 4. The web platform 2 is in a load-bearing state when it abuts against the support base 4. By setting the support base 4, the web platform 2 can safely support the web steel mesh 200 when in a load-bearing state.

[0053] In this embodiment, the base plate platform 1 and the web plate platform 2 are rotatably connected by a transition shaft 5. The transition shaft 5 passes through one end of the web plate platform 2 and one end of the base plate platform 1. The support seat 4 and the base plate platform 1 are spaced apart. In the load-bearing state, the web plate platform 2 is supported by the transition shaft 5 and the support seat 4.

Two drive racks are arranged facing each other and mesh with opposite sides of the drive gear. This arrangement allows the driver 31 to drive the drive module 32 to move more precisely.

[0057] In this embodiment, the motor is fixedly installed on the base plate platform 1, the axis of the output shaft extends along the vertical second direction, the drive gear is fixedly mounted on the output shaft of the motor, the two drive racks are located in the same horizontal plane, parallel to each other and spaced apart, the drive gear is located between the two drive racks, when the motor drives the drive gear to rotate, the two drive racks move towards or away from each other, thereby driving the two drive modules 32 to move towards or away from each other.
