Technical Field

[0001] The invention relates to the technical field of prefabricated box girders, and in particular to a material distribution device for bottom web reinforcement bars of prefabricated box girders. Background Art

[0002] When manufacturing prefabricated box girders, the bottom web reinforcement needs to be fixed in a preset position by tying to prevent the displacement of the reinforcement during the concrete pouring process and to confirm the accuracy of the box girder structure. The tied reinforcement can form an overall force system, enhance the bearing capacity of the beam, and reduce the slippage and dislocation between the reinforcements, ensuring uniform force and thus improving the stability of the structure. Therefore, reinforcement tying is one of the key processes for quality control of prefabricated box girders, and must be carried out in strict accordance with the construction specifications to ensure the quality of the project.

[0003] The patent application document with publication number CN117734009A discloses a reinforcement placing machine for the bottom web of a small highway box girder, comprising: a circulating feeding mechanism, used to convey frame reinforcement in a fixed direction and guide the frame reinforcement to fall; a material drop opening, which is arranged on the circulating feeding mechanism, for the frame reinforcement to fall; a storage rack, which is arranged below the circulating feeding mechanism, for receiving the frame reinforcement; a plurality of storage slots, which are arranged on the storage rack, for placing the frame reinforcement; and a differential mechanism, which is used to drive the circulating feeding mechanism and the storage rack to produce relative movement, so that the material drop opening is located above different storage slots.

[0004] However, this solution still has the following problems: when placing the frame bars on the fabric machine, they still need to be placed one by one, and when the frame bars fall into the corresponding storage grooves, because in the initial state, there is a certain distance between the frame bars and the storage grooves, the frame bars may be tilted during the falling process, resulting in failure to accurately fall into the storage grooves, requiring manual adjustment, affecting the fabric efficiency. Summary of the invention

A push rod 6 is arranged on the transfer rack 2, and the insertion rod 4 is slidably arranged outside the push rod 6, that is, the push rod 6 is slidably inserted in the insertion rod 4, and the push rod 6 is used to cooperate with the control member 5, and the control member 5 is used to open or close the card slot 41. A baffle 7 is arranged on the transfer rack 2. When the insertion rod 4 moves, it drives multiple card slots 41 to pass through the baffle 7 in sequence. When the card slot 41 passes through the baffle 7, the push rod 6 drives the control member 5 to drive the card slot 41. When laying the material, multiple frame ribs 01 are arranged and placed on the insertion rod 4, and multiple frame ribs 01 are placed on one side of the baffle 7. The insertion rod 4 moves to drive the frame ribs 01 to move through the baffle 7. At the same time, the slots 41 moved to the baffle 7 are opened under the action of the top rod 6, and the frame ribs 01 moved to the baffle 7 are placed in the slots 41 in turn. Finally, multiple frame ribs 01 are placed in the designated slots 41 respectively, so that the frame ribs 01 can be placed on the placement rack 3 later.

The second elastic member 62 is used to drive the push block 63 to move toward the outside of the top groove 61, and a chamfer is arranged on the side of the push block 63 arranged outside the top groove 61. When the top rod 6 moves relative to the insertion rod 4, the chamfer of the push block 63 is brought into contact with the edge of the push block 63, thereby adjusting the position of the clamping block 52. After the clamping block 52 moves to separate from the clamping slot 41, the clamping slot 41 opens, and the frame rib 01 enters the clamping slot 41. The insertion rod 4 is continuously moved, and the push block 63 enters the top slot 61 under the action of the chamfer and separates from the clamping block 52. The clamping block 52 abuts against the frame rib 01 under the action of the elastic member 1 51. As the insertion rod 4 continues to move, the push block 63 moves to open multiple clamping slots 41, so that multiple frame ribs 01 enter the corresponding clamping slots 41 in sequence.

[0043] Two baffles 7 are provided along the moving direction of the insertion rod 4, and the push block 63 corresponds to the gap between the two baffles 7, that is, when the slot 41 moves to the gap between the two baffles 7, the push block 63 drives the corresponding slot 41 to open.

After the frame bars 01 are placed on the placement rack 3, the transfer rack 2 is moved in the opposite direction to remove the insertion rod 4 so as to transport the frame bars 01 again. Two pushers 92 and guide rails 93 are provided correspondingly, and the two pushers 92 are respectively provided at both ends of the guide rails 93, thereby improving the stability of the guide rails 93 when moving.

[0047] Reference Figure 1 and Figure 2 The placement rack 3 includes a base 31 and a support rack 32. The base 31 is provided with a plurality of fixing grooves, which are used to fix the bottom of the frame rib 01. The support rack 32 includes an inclined support portion 321, which is used to support the side of the frame rib 01. Pushing piece 1 91 and pushing piece 2 92 drive the frame rib 01 to move toward the base 31 until the bottom of the frame rib 01 is stuck in the fixing groove, and the side of the frame rib 01 abuts against the support portion 321, and the frame rib 01 is placed at an equal distance at a designated position for subsequent binding.
