Description

Technical Field

[0002] In modern building structures, steel cages are used in conjunction with concrete to create reinforced concrete structures. Concrete has high compressive strength but very low tensile strength. Steel cages can provide support, tensile strength, and resistance to bending / seismic forces. They also restrain the concrete pile body, enabling it to withstand a certain axial tensile force, thus giving reinforced concrete good comprehensive performance.

[0003] In the existing production process of steel cage structures, taking rectangular steel cage skeletons as an example, rectangular steel cage skeletons generally include rectangular stirrups and longitudinal bars perpendicular to the stirrups. Among them, most of them are made by manually threading the longitudinal bars into the stirrups on site. This traditional manual threading method is not only extremely inefficient, but also has a large human error, which seriously affects the production efficiency of rectangular steel cage skeletons.

The left motor drives the gear to mesh with the rack on the left base plate 221 to drive the left base plate 221 to move along the vertical direction.

[0097] A guide rail is provided on the right frame 23 along the vertical direction. The right base plate 231 moves along the guide rail on the right frame 23. A rack is provided on the right base plate 231 along the vertical direction. A right motor 233 is fixed on the right frame 23. A gear is connected to the output end of the right motor 233. The right motor 233 drives the gear to mesh with the rack on the right base plate 231, thereby driving the right base plate 231 to move vertically. In one embodiment of this application, the left base plate 221 is adjusted in the vertical direction relative to the left frame 22, and the right base plate 231 is adjusted in the vertical direction relative to the right frame 23, so that the left base plate 221 and the right base plate 231 are better aligned with the longitudinal reinforcement 4 corresponding to stirrups of different sizes, so as to be suitable for the stirrup threading operation of different sizes.

[0098] The top substrate 241 is vertically guided and mounted on the top frame 24. A rack is mounted on the top substrate 241 in the vertical direction. A motor is mounted on the top frame 24. A gear is mounted on the motor's conveying end. The gear meshes with the rack on the top substrate 241 to drive the top substrate 241 to move up and down.

[0099] The base plate 211 is vertically guided and mounted on the base frame 21. A rack is mounted on the base plate 211 vertically. A motor is mounted on the base frame 21. A gear is mounted on the motor's conveying end. The gear meshes with the rack on the base plate 211 to drive the base plate 211 to move up and down.

[0100] In one embodiment of this application, the top base plate 241 and the bottom base plate 211 can move toward the stirrups to adjust the spacing between the top frame 24 and the bottom frame 21, so that the longitudinal reinforcement transition unit 2 has a wider range of longitudinal reinforcement 4 adjustment spacing to be suitable for stirrup threading operations of different sizes.

[0101] In this embodiment, four longitudinal reinforcement transition units 2 are provided on the conveying track 1 for reinforcement threading operations.

[0102] When using the synchronous conveying and transition device for the longitudinal reinforcement of the rectangular steel cage 4, the following steps are included:

[0103] Step 1: Place the two longitudinal ribs 4 on the support frames 33 on the two feeding racks 32 respectively, then adjust the horizontal position of the two feeding racks 32 simultaneously, and then adjust the vertical position of the two support frames 33 simultaneously; control the conveying wheel 34 on the support frame 33 to rotate, so that the two longitudinal ribs 4 are conveyed to the guide wheel 25 of the longitudinal rib transition unit 2.

[0104] Step 2, repeat step 1 until all longitudinal ribs 4 in the longitudinal rib transition unit 2 have been fed. The pressure block 29 descends to press the longitudinal ribs 4 on the guide wheel 25.

[0105] Step 3: Adjust the relative positions of the bottom frame 21, top frame 24, left frame 22 and right frame 23 so that their positions can match the stirrup dimensions.

[0106] Step 4: Simultaneously adjust the spacing of the V-shaped folding connecting rod 28 assemblies on the bottom substrate 211, top substrate 241, left substrate 221 and right substrate 231 so that the guide wheels 25 on the bottom substrate 211, top substrate 241, left substrate 221 and right substrate 231 can correspond to the position where the longitudinal reinforcement 4 needs to be installed.

[0107] Step 5: Multiple longitudinal reinforcement transition units 2 move forward synchronously to insert the longitudinal reinforcement 4 into the stirrups located downstream of the conveying guide rail; when a longitudinal reinforcement transition unit 2 moves to the point of interference, its pressure block 29 is controlled to move upward to loosen the longitudinal reinforcement 4.

[0108] Step 6: When the last longitudinal reinforcement transition unit 2 moves to the point of interference, control its pressure block 29 to move upward to loosen the longitudinal reinforcement 4; and after multiple longitudinal reinforcement transition units 2 move back a set distance, lower the pressure block 29 again to clamp the longitudinal reinforcement 4, and then control the longitudinal reinforcement transition unit 2 to move forward to continue the reinforcement insertion operation. Repeat the above process until the longitudinal reinforcement 4 is completely inserted into the stirrup.
