In the embodiment, the small box girder is taken as an example for description.

[0023] As Figure 1 , 2As shown, the box girder steel bar self-adaptive distribution device of the embodiment of the utility model, for the distribution of longitudinal reinforcement 1 in box girder manufacturing, the box girder steel bar self-adaptive distribution device contains positioning module 3 and base 4, as the basic support structure of the whole device, base 4 can move relative to the external reinforcement clamping mechanism under the drive of drive device 5, this provides the basic condition for realizing the self-adaptive distribution of reinforcement. Base 4 is the force basis of support bracket 31 supporting reinforcement, ensures the stability of support bracket 31 and the load-bearing capacity, is important to ensure the normal operation of the whole device. Positioning module 3 contains: a plurality of support brackets 31, a plurality of positioning grooves 32 and locking assemblies 33.

[0024] Specifically, as shown, Figure 1 A plurality of support brackets 31 are arranged on base 4, and the plurality of support brackets 31 can move relative to base 4; the support bracket 31 can be flexibly adjusted according to the specifications and spacing of the reinforcement, so as to realize the self-adaptive distribution of the reinforcement. The number and arrangement mode of the support bracket 31 can be flexibly set according to actual needs. The positioning groove 32 corresponds to the support bracket 31 one by one, the positioning groove 32 is arranged at the end of the support bracket 31, and the positioning groove 32 and the base 4 are located at the two ends of the support bracket 31 respectively; the main role of the positioning groove 32 is to ensure that the reinforcement can be accurately placed at the predetermined position, and prevent the reinforcement from being displaced or deformed during processing or transportation. The internal shape and opening size of the positioning groove 32 can be matched according to the shape of the reinforcement. The locking assembly 33 locks or unlocks the support bracket 31 on the base 4, specifically, when the support bracket 31 is adjusted to the appropriate position according to product requirements, the locking assembly 33 can lock the support bracket 31, ensure the stability of the support bracket 31, and prevent it from moving in the subsequent processing process. The locking assembly 33 is reliable and easy to use, and is important to improve the use efficiency of the whole device.

[0025] Preferably, the locking assembly 33 is a self-locking type locking assembly, which can be self-locked on the base 4 without external force, which greatly saves the time of locking the support bracket 31 and the base 4, further improves the production efficiency, and at the same time enhances the safety and stability of the device. During the reinforcement distribution process, even if unexpected situations such as sudden power failure or external force interference occur, the support bracket 31 will not move due to the loss of locking, thereby ensuring the accuracy of the reinforcement position and the safety of the processing process.

[0026] Preferably, the self-locking type locking assembly contains first engagement teeth 5 arranged on the base 4 and second engagement teeth arranged on the support bracket 31, the first engagement teeth 5 and the second engagement teeth are oppositely arranged, and the first engagement teeth 5 and the second engagement teeth are coupled.

This design not only improves the reliability of the locking assembly 33, but also makes the support bracket 31 more stable when bearing the weight of the reinforcement and various forces in the construction process, further ensuring the safety and quality of the construction

[0027] Preferably, the connection between the locking assembly 33 and the support 31 is provided with a rotating shaft 6, and the locking assembly 33 rotates around the rotating shaft 6 when it is locked or unlocked. The design of the rotating shaft 6 allows the second clamping teeth of the locking assembly 33, especially in the self-locking type, to rotate around the shaft center when it is locked or unlocked, which is simple in structure and smooth in operation, and connects the support 31 and the locking assembly 33, and realizes the self-locking function.

[0028] Preferably, the rotating shaft 6 is provided with a clamping spring at both ends. The addition of the clamping spring further enhances the stability of the locking assembly 33, prevents the rotating shaft 6 from loosening or falling off during the force process, and thus ensures the durability and reliability of the locking assembly 33.

[0029] Preferably, the locking assembly 33 further comprises an unlocking mechanism 331, which can separate the support 31 and the base 4 and relatively move the support 31 along the extension direction of the base 4, so as to realize that the device can be applied to more types of box girder products and steel bar specifications, and enhance the versatility and flexibility of the device.

[0030] Preferably, the first embodiment of the unlocking mechanism 331 comprises a stripping rod, a driving rod and a power assembly. Under the driving force of the power assembly, the stripping rod exerts force on the support 31 along the extension direction of the steel bar to separate the support 31 and the base 4, and the driving rod exerts force on the support 31 along the radial direction of the steel bar section to drive the support 31 to relatively move with the base 4. This realizes the rapid unlocking and movement of the support 31, thereby improving the construction efficiency.

[0031] Preferably, the second embodiment of the unlocking mechanism 331 integrates the stripping and driving mechanisms in one, and the specific structure comprises a stripping and driving rod, a through hole provided on the support 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 and driving rod can extend into the through hole and separate the support 31 and the base 4, and the side of the stripping and driving rod can drive the side wall of the through hole to drive the support 31 to relatively move with the base 4. Through the design of the through hole, the structure of the stripping and driving movements is integrated, and it is realized by one rod-shaped mechanism, which further simplifies the structure, saves space, enhances the integration of the whole device, and reduces the cost and maintenance cost of the mechanism.

[0032] Preferably, the base 4 is provided with a sliding rail 7, and the support 31 is provided with a sliding block. The sliding block slides along the extension direction of the sliding rail 7. The design of the sliding rail 7 and the sliding block makes the movement of the support 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 support 31 during the movement, prolonging the service life of the device.

[0033] Preferably, the sliding rail 7 is provided with a sensor outside, which detects the position of the sliding block. The addition of the sensor realizes real-time monitoring of the position of the sliding block, so that the construction personnel can more accurately master the position information of the support 31, thereby further improving the efficiency and precision of the reinforcement positioning.

[0034] In use, the number, position and distance of the longitudinal reinforcement 1 are designed according to the parameters of the batch of processed products, and each support 31 is adjusted to the corresponding position: in the adjustment process, the stripping drive rod pushes one end of the support 31 to unlock the support 31, so that the support 31 can move under the drive of the drive assembly. Specifically, the stripping drive rod pushes the side wall of the through hole of the support 31, so that the support 31 can move relative to the extension direction of the base 4, and finally reach the preset position. After each support 31 is distributed according to the above steps, the support 31 and the base 4 are self-locked by the engagement teeth when the stripping drive rod extends out of the through hole and is separated from the support 31. Further, through the relative displacement between the base 4 and the external clamping module, the longitudinal reinforcement 1 can be placed one by one into the positioning groove 32 at the upper end of the support 31, and finally a group of reinforcements are distributed. After the distribution is completed, the welding device 8 reaches the connection between the longitudinal reinforcement 1 and the transverse hoop reinforcement 2 by adjusting the position of the module 81, and after the shaping module 82 shapes the longitudinal reinforcement 1 and the transverse hoop reinforcement 2, further welding is performed to complete the manufacture of the box girder.

[0035] The above, with reference to Figure 1 The box girder reinforcement self-adaptive distribution device according to the embodiments of the utility model is described, which upgrades the positioning module 3 customized according to the characteristics of each batch of products to a self-adaptive positioning module 3 capable of self-adaptively adjusting the reinforcement distribution spacing and the number of supports 31, improves the problems of the traditional box girder reinforcement arrangement relying on inaccurate manual measurement, time-consuming and laborious, or the one-time use problem caused by the need for customized module for each batch, not only improves the original low efficiency problem, but also realizes millimeter-level control of the reinforcement position through accurate sensors and automatic algorithms, thereby ensuring that the distribution of the reinforcement in the box girder meets the design requirements, ensuring the precision and improving the mechanical properties and durability of the bridge. Key, the core competitiveness of the self-adaptive distribution device can automatically adjust the spacing and number of supports 31 according to the characteristics of different box girder products, thereby meeting the diversified production needs, no longer needing the time cost of customizing the positioning module 3, making the box girder production more flexible, being able to quickly respond to market changes, and improving the utilization rate and competitiveness of the production line.
