Description

Technical Field

[0001] This utility model relates to the field of steel cage production technology, and in particular to an automatic feeding bin for box girder frames. Background Technology

[0002] In municipal road and bridge construction, box girders are indispensable. To improve construction efficiency, the structural components and internal reinforcing steel cages of box girders are usually prefabricated. The box girder reinforcing cage includes the box girder steel reinforcement skeleton. During the fabrication of the box girder steel reinforcement skeleton, the arranged bottom and web stirrups of the box girder need to be welded into a three-in-one combined stirrup. External longitudinal bars are welded to the outside of the web stirrups of the combined stirrup, and internal longitudinal bars are welded to the inside of the bottom stirrups of the combined stirrup, thus forming the box girder steel reinforcement skeleton.

[0003] Patent CN113927732B discloses a processing system and method for stirrups in the bottom and web plates of a small box girder. The system includes a CNC stirrup bending machine, welding equipment, and a storage device. The storage device includes guide rails and an electrically movable support platform. Two support beams arranged in the same direction are mounted on the upper part of the electrically movable support platform. The platform includes a support plate with two vertical columns, and the support beams are connected to the upper part of the columns. When storing the bottom and web plate stirrups in the storage device, the stirrups on both sides of the web plate are simply hooked onto the two support beams of the processing device.

[0004] Currently, when welding the bottom and web slab stirrups together with the web longitudinal bars and bottom slab longitudinal bars to form the box girder reinforcement skeleton, the stirrups need to be arranged on a jig, and then the web longitudinal bars and bottom slab stirrups need to be passed through the stirrups and installed close to the stirrups to weld the web longitudinal bars, bottom slab longitudinal bars and stirrups together. This process is cumbersome and requires a lot of manpower. Utility Model Content

[0005] In view of the above problems, this utility model provides an automatic feeding bin for box girder frames.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0007] An automatic feeding bin for box girder skeleton is provided, including a bin skeleton and a bin placement base. The bin skeleton is movably mounted on the bin placement base. The bin skeleton has a storage cavity for storing three-in-one stirrups. One end of the storage cavity has an outlet for the three-in-one stirrups to enter and exit. Wire longitudinal bar guide tubes are provided on both sides of the web stirrups of the three-in-one stirrups in the bin skeleton. Bar longitudinal bar guide tubes are provided on the inner side of the bottom stirrups of the three-in-one stirrups in the bin skeleton. A pushing component is provided on the bin skeleton for pushing the three-in-one stirrups in the storage cavity to the outlet of the storage cavity.

[0008] Furthermore, the feeding assembly includes a drive screw, a slider, and a push rod. The slider is slidably mounted on the hopper frame along the depth direction of the storage cavity. A threaded sleeve is fixedly mounted on the slider. The threaded sleeve is fitted onto the drive screw and threadedly connected to the drive screw. Both ends of the drive screw are rotatably connected to the hopper frame. A mounting plate is mounted on the end of the hopper frame away from the outlet of the storage cavity. A first drive motor for driving the drive screw to rotate is mounted on the mounting plate. The push rod is fixedly mounted on the slider, and the end of the push rod away from the slider extends into the storage cavity.

[0009] Furthermore, symmetrical drive and pushing components are provided on both sides of the hopper frame, and a first drive motor is provided on the mounting plate. The first drive motor is simultaneously connected to the drive screws in the two sets of pushing components.

[0010] Furthermore, the wire rod longitudinal reinforcement guide tube includes a support plate and several first reinforcement delivery pipes. The support plate is fixedly installed on the silo frame. Several installation grooves are opened on the edge of the support plate near the storage cavity. Several first reinforcement delivery pipes are correspondingly and fixedly installed in each installation groove. The two ends of the first reinforcement delivery pipes have through openings. The first reinforcement delivery pipes are used to allow the web longitudinal reinforcement to pass through.

[0011] Furthermore, the bar longitudinal rib guide pipe includes several second rib delivery pipes, with openings at both ends of the second rib delivery pipes. The several second rib delivery pipes are spaced apart along the width direction of the silo frame. One end of the bar longitudinal rib guide pipe passes through the mounting plate and is fixedly connected to the mounting plate. The second rib delivery pipes are used to supply the longitudinal ribs of the bottom plate.

[0012] Furthermore, guide blocks are provided on both sides of the silo placement base and at the end away from the storage chamber outlet, and guide ramps are provided on the upper edge of the side of the guide blocks near the silo frame.

[0013] The beneficial effects of this utility model are as follows: After the silo frame filled with three-in-one stirrups is placed on the silo placement base by a crane, the drive screws on both sides of the silo frame rotate synchronously, causing the two push rods to gradually push the three-in-one stirrups in the silo frame towards the outlet of the storage cavity. Then, the wire longitudinal bar guide tube and bar longitudinal bar guide tube on the silo frame guide the web longitudinal bars and bottom plate longitudinal bars respectively, so that the web longitudinal bars and bottom plate longitudinal bars remain close to the outer wall of the web stirrups and close to the inner top wall of the bottom plate stirrups after leaving the silo frame. This facilitates the welding equipment to quickly weld the web longitudinal bars, bottom plate longitudinal bars and three-in-one stirrups into a box girder frame, thus improving the welding efficiency of the box girder frame.
