Description

Technical Field

[0001] The invention relates to the technical field of box girder manufacturing, and in particular to a box girder steel bar adaptive distribution device. Background Art

[0002] The box girder is a beam structure with a hollow rectangular cross-section. It has the characteristics of high rigidity, large bearing capacity, and beautiful structure. It is widely used in highway, high-speed railway, and bridge construction. The steel bars in the box girder mainly include longitudinal steel bars 1 and transverse stirrups 2, which play an important role in the box girder structure. In the design and construction, the number, spacing and other parameters of the longitudinal steel bars and transverse stirrups need to be reasonably configured according to the force characteristics and bearing requirements of the specific construction conditions to ensure the firmness and stability of the entire infrastructure structure. Therefore, in production, the number and spacing of the longitudinal steel bars need to be customized according to the needs of the product.

[0003] In the existing production line, the core of the distribution mechanism is the positioning module, which is customized according to the requirements of each batch of products. The positioning module can determine the number, position and spacing of the longitudinal steel bars 1 to ensure that the distribution of the steel bars in the structure meets the engineering requirements. They are usually composed of a series of brackets and positioning slots, which are installed on the base as a whole and move relative to the base as a whole in the production line; the brackets and positioning slots can firmly support the steel bars to prevent them from shifting or deforming during processing or transportation. After the longitudinal steel bars are loaded, the clamping mechanism distributes the longitudinal steel bars in the positioning module in sequence to complete the distribution and cyclic processing. However, with the improvement of production efficiency requirements, it takes a certain amount of time to customize the positioning module for each batch, and it is also a cost expenditure that cannot be ignored. With the continuous development of infrastructure technology, the types and specifications of box girders are becoming more and more abundant. Therefore, designing a positioning module that can be flexibly adjusted and even adaptive to products can greatly improve efficiency and reduce costs, which is a technical problem to be solved by technicians in this field.

[0021] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0022] First, combine Figure 1 , 2 The box girder reinforcement adaptive distribution device according to the embodiment of the present invention is widely used in scenes such as highway, high-speed railway, and bridge construction. In this embodiment, a small box girder is taken as an example for description.

[0023] like Figure 1 , 2As shown, the box girder reinforcement adaptive distribution device of the embodiment of the present invention is used to distribute longitudinal reinforcement 1 in the manufacture of box girders. The box girder reinforcement adaptive distribution device comprises a positioning module 3 and a base 4. As the basic support structure of the entire device, the base 4 can move relative to the external reinforcement clamping mechanism under the drive of the driving device 5, which provides the basic conditions for realizing the adaptive distribution of reinforcement. The base 4 is the force-bearing foundation for the support 31 to support the reinforcement. Ensuring the stability and proper load-bearing capacity of the support 31 is crucial to ensuring the normal operation of the entire device. The positioning module 3 comprises:

[0024] A plurality of brackets 31 , a plurality of positioning slots 32 and a locking assembly 33 .

[0025] Specifically, Figure 1 As shown, several brackets 31 are arranged on the base 4, and several brackets 31 can be relatively displaced with the base 4; the brackets 31 can be flexibly adjusted according to the specifications and spacing of the steel bars, so as to realize the adaptive distribution of the steel bars. The number and arrangement of the brackets 31 can be flexibly set according to actual needs. The positioning grooves 32 correspond to the brackets 31 one by one, and the positioning grooves 32 are arranged at the ends of the brackets 31. The positioning grooves 32 and the base 4 are respectively located at the two ends of the brackets 31; the main function of the positioning grooves 32 is to ensure that the steel bars can be accurately placed in the predetermined position to prevent the steel bars from shifting or deforming during processing or transportation. The internal shape and opening size of the positioning grooves 32 can be matched according to the shape of the steel bars. The locking assembly 33 locks or unlocks the bracket 31 to the base 4. Specifically, when the bracket 31 is adjusted to a suitable position according to product requirements, the locking assembly 33 can lock the bracket 31 to ensure the stability of the bracket 31 and prevent it from moving during subsequent processing. The locking assembly 33 is reliable and easy to use, which is crucial to improving the efficiency of the entire device.

[0026] Preferably, the locking assembly 33 is a self-locking locking assembly, which can be self-locked on the base 4 when not subject to external force, which greatly saves the time required to lock the bracket 31 and the base 4, further improves production efficiency, and enhances the safety and stability of the device. During the distribution of steel bars, even if an unexpected situation occurs, such as a sudden power outage or external force interference, the bracket 31 will not move due to loss of locking, thereby ensuring the accuracy of the steel bar position and the safety of the processing process.

[0027] Preferably, the self-locking locking assembly comprises a first meshing tooth 5 provided on the base 4 and a second meshing tooth provided on the bracket 31, the first meshing tooth 5 and the second meshing tooth are arranged opposite to each other, and the first meshing tooth 5 and the second meshing tooth are coupled. The locking assembly 33 has stronger anti-shear and anti-slip capabilities in the locked state and is relatively simple in structure and maintenance. This design not only improves the reliability of the locking assembly 33, but also makes the bracket 31 more stable when bearing the weight of the steel bars and various forces during the construction process, further ensuring the safety and quality of the construction.

[0028] Preferably, a rotating shaft 6 is provided at the connection between the locking assembly 33 and the bracket 31, and when the locking assembly 33 is locked or unlocked, the locking assembly 33 rotates around the rotating shaft 6. The design of the rotating shaft 6 enables the locking assembly 33, especially in the self-locking type locking assembly, the second engaging tooth to rotate around the axis when locked or unlocked, with a simple structure and smooth operation process, connecting the bracket 31 and the locking assembly 33, and realizing the self-locking function.

[0029] Preferably, a retaining spring is provided at both ends of the rotating shaft 6. The addition of the retaining spring further enhances the stability of the locking assembly 33, prevents the rotating shaft 6 from loosening or falling off during the force-bearing process, and thus ensures the long-term reliability of the locking assembly 33.

[0030] Preferably, the locking assembly 33 also includes an unlocking mechanism 331, which can separate the bracket 31 and the base 4 and enable the bracket 31 to move relatively along the extension direction of the base 4, so that the device can be applicable to more types of box girder products and steel bar specifications, thereby enhancing the versatility and flexibility of the device.

[0031] Preferably, the first embodiment of the unlocking mechanism 331 includes a stripping rod, a driving rod and a power assembly, and when the power assembly provides driving force, the stripping rod applies force to the bracket 31 along the extension direction of the steel bar to separate the bracket 31 and the base 4, and the driving rod applies force to the bracket 31 along the radial direction of the steel bar cross section to drive the bracket 31 to move relative to the base 4. The bracket 31 is quickly unlocked and moved, thereby improving construction efficiency.

[0032] Preferably, the second embodiment of the unlocking mechanism 331 integrates the two mechanisms of stripping and driving. The specific structure includes a stripping driving rod, a through hole provided on the bracket 31, and a driving assembly. The driving assembly provides power. The axial direction of the through hole is the same as the extension direction of the steel bar. The end of the stripping driving rod can extend into the through hole and separate the bracket 31 from the base 4. The side of the stripping driving rod can drive the side wall of the through hole to drive the bracket 31 and the base 4 to move relative to each other. Through the design of the through hole, the structure of the two steps of stripping and driving movement is integrated into one, and is realized by a rod-shaped mechanism at the same time, which further simplifies the structure, saves space, enhances the integration of the entire device, and reduces the cost and maintenance cost of the mechanism.

[0033] Preferably, a slide rail 7 is provided on the base 4, and a plurality of brackets 31 are respectively provided with sliders, which slide along the extending direction of the slide rail 7. The design of the slide rail 7 and the slider makes the movement of the bracket 31 on the base 4 more stable and accurate. This not only improves the accuracy of the steel bar arrangement, but also reduces the friction and wear of the bracket 31 during the movement, thereby extending the service life of the device.

[0034] Preferably, a sensor is provided on the outside of the slide rail 7 to detect the position of the slider. The addition of the sensor enables real-time monitoring of the slider position, so that construction personnel can more accurately grasp the position information of the bracket 31, thereby further improving the efficiency and accuracy of steel bar positioning.

[0035] When in use, the number, position and distance of the longitudinal steel bars 1 are designed according to the parameters of the processed products of this batch, and each bracket 31 is adjusted to the corresponding position: during the adjustment process, the stripping driving rod pushes one end of the bracket 31 to unlock the bracket 31, so that the bracket 31 can move under the drive of the driving assembly. Specifically, the stripping driving rod pushes the side wall of the through hole of the bracket 31, so that the bracket 31 can move relative to the extension direction of the base 4 and finally reach the preset position. After each bracket 31 is distributed according to the above steps, each time the stripping driving rod extends out of the through hole to disengage the bracket 31, the bracket 31 and the base 4 are self-locked and locked by the bite teeth. Further, through the relative displacement between the base 4 and the external clamping module, the longitudinal steel bars 1 can be placed one by one in the positioning groove 32 at the upper end of the bracket 31, and finally a group of steel bars are distributed. After the distribution is completed, the welding device 8 reaches the connection between the longitudinal steel bars 1 and the transverse stirrups 2 by the drive of the position adjustment module 81. After the shaping module 82 shapes the shaped longitudinal steel bars 1 and the transverse stirrups 2, further welding is performed to complete the manufacture of the box girder.

[0036] Above, refer to Figure 1The invention describes a box girder reinforcement adaptive distribution device according to an embodiment of the present invention. By upgrading the positioning module 3 customized according to each batch of products to an adaptive positioning module 3 capable of adaptively adjusting the reinforcement distribution spacing and the number of brackets 31 according to the box girder products, the conventional box girder reinforcement arrangement relies on inaccurate manual measurement, which is time-consuming and labor-intensive, or the one-time use problem caused by the need to customize the module for each batch, which not only improves the original low efficiency problem, but also realizes millimeter-level control of the position of the reinforcement through precise sensors and automated algorithms, thereby ensuring that the distribution of the reinforcement in the box girder meets the design requirements, ensuring accuracy, and improving the mechanical properties and durability of the bridge. Crucially, the core competitiveness of the adaptive distribution device can automatically adjust the spacing and number of brackets 31 according to the characteristics of different box girder products in a targeted manner, thereby meeting the diversified production needs, and no longer requiring the time cost of customizing the positioning module 3, making the box girder production more flexible, able to quickly respond to market changes, and improving the utilization rate and competitiveness of the production line.
