Description

Fabric laying unit, longitudinal reinforcement laying equipment and fabric laying method

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on August 2, 2023, with application number 202310963369.1, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of building construction, for example, to a laying unit, longitudinal reinforcement laying equipment and a laying method. Background Art

[0003] As a retaining structure, underground diaphragm walls offer advantages such as high strength, a small footprint, and excellent anti-seepage properties, making them widely used in foundation pit construction. The main construction process involves using a trenching machine to excavate a trench of a certain length, lowering a reinforcement cage into the trench, and finally pouring concrete within the trench. This completes the construction of a single trench section. This process continues step by step, creating the reinforced concrete wall of the underground diaphragm wall.

[0004] The reinforcement cage of an underground continuous wall is primarily welded together from longitudinal bars, transverse bars, sealing bars, and trusses. Longitudinal bars are arranged along the length of the cage and serve as the main load-bearing bars. Transverse bars are placed at regular intervals on the longitudinal bars to connect multiple longitudinal bars together. Sealing bars are placed at the ends of the cage to form a closed loop. Trusses are placed inside the cage to increase its strength. During the cage fabrication process, longitudinal bars are first arranged at regular intervals in the welding area. Transverse bars are then placed above the longitudinal bars and welded to form a lower mesh. Trusses are then welded above the lower mesh. Finally, longitudinal bars are welded above the trusses to form the mesh, forming the cage. Sealing bars are then welded to both ends of the cage.

[0005] In the above-mentioned production process, due to the long length of the longitudinal reinforcement, it is usually necessary to connect multiple short steel bars into one longitudinal reinforcement, and multiple construction workers will carry the connected longitudinal reinforcement to the designated area of ​​the welding area, and control the spacing between two adjacent longitudinal reinforcements by manual placement to complete the arrangement of the longitudinal reinforcement. At the same time, during the reinforcement arrangement process on the mesh sheet, since the reinforcement arrangement position is above the ground, the construction workers also need to lift the steel bars and climb onto the mesh sheet to carry the steel bars. Such operation is time-consuming and labor-intensive, consumes a lot of manpower, is highly dangerous, and cannot accurately control the arrangement position of the longitudinal reinforcement.

[0045] 1 and 2 , this embodiment provides a material distribution unit configured to transport steel bars 100 to a welding platform 200 for manufacturing steel bar cages, and includes a carrying platform 1 , a material discharging mechanism 2 , and a material loading mechanism 3 .

[0046] The carrying platform 1 is movably disposed at one end of the welding platform 200 and is configured to carry the steel bars 100. The blanking mechanism 2 includes a movable bracket 21 and a blanking assembly 22 disposed on the movable bracket 21. The movable bracket 21 is movably disposed on the carrying platform 1 and can be moved to a preset position above the welding platform 200. The movable bracket 21 can carry the steel bars 100. The blanking assembly 22 can flip the steel bars 100 from the movable bracket 21 onto the welding platform 200. The loading mechanism 3 is disposed on the carrying platform 1 and is movable along the extension direction of the carrying platform 1. The loading mechanism 3 includes a grabbing assembly and a detection element 32. The grabbing assembly is configured to grab the steel bars 100 on the carrying platform 1. The steel bars 100 grabbed by the grabbing assembly can be transported to the movable bracket 21 by moving the loading mechanism 3. The detection element 32 is configured to detect whether there are steel bars 100 placed on the carrying platform 1.

[0047] When using the material distribution unit provided in this embodiment, a rebar 100 is first placed on the carrying platform 1. The carrying platform 1 is then driven to a preset height, while the loading mechanism 3 is simultaneously driven to reciprocate along the extension direction of the carrying platform 1. The detection element 32 can detect the carrying platform 1 in real time. When the presence of a rebar 100 on the carrying platform 1 is detected, the loading mechanism 3 is driven to move to the location of the rebar 100 and transport the rebar 100 to the mobile support 21. The mobile support 21 is then driven to a preset position above the welding platform 200. Finally, the blanking assembly 22 is driven to drop the rebar 100 to the preset position on the welding platform 200. The carrying platform 1 provides stable support for the rebar 100. Since the carrying platform 1 can be raised or lowered, it can be positioned at an appropriate height to facilitate welding of the mesh sheet of the rebar cage. This eliminates the need for construction workers to manually lift the rebar during mesh welding, facilitating operation and ensuring worker safety. By driving the mobile bracket 21 to move, the steel bar 100 can be transported to any position above the welding platform 200. When the steel bar 100 is transported to the preset position of the welding platform 200, the steel bar 100 is flipped onto the welding platform 200 by the blanking assembly 22, and the steel bar 100 can be arranged at the preset position of the welding platform 200. That is, the layout position of the steel bar 100 can be accurately controlled by the mobile bracket 21 and the blanking assembly 22, thereby improving the reinforcement accuracy of the steel bar 100 and ensuring the structural strength of the steel cage.

[0048] Optionally, the detection element 32 is communicatively connected to the control unit of the longitudinal reinforcement laying equipment. The detection element 32 is a laser sensor, which has high precision and strong anti-interference ability.

[0049] Optionally, referring to Figures 3 and 4, the grabbing assembly includes a first material fork 311 and a second material fork 312 disposed oppositely. A first guide rail 11 and a second guide rail 12 are disposed oppositely on the carrying platform 1. The first guide rail 11 and the second guide rail 12 both extend along the extension direction of the carrying platform 1. The first material fork 311 is slidably connected to the first guide rail 11, and the second material fork 312 is slidably connected to the second guide rail 12. The first material fork 311 and the second material fork 312 are both liftable. By lifting, the first material fork 311 and the second material fork 312 can lift the steel bar 100 on the carrying platform 1. This arrangement achieves a sliding connection between the first material fork 311 and the second material fork 312 and the carrying platform 1. The first guide rail 11 can provide a guide for the movement of the first material fork 311, and the second guide rail 12 can provide a guide for the movement of the second material fork 312, thereby ensuring the stability of the movement of the first material fork 311 and the second material fork 312. At the same time, the first guide rail 11 can also limit the movement of the first material fork 311, and the second guide rail 12 can limit the movement of the second material fork 312, thereby preventing the first material fork 311 and the second material fork 312 from detaching from the supporting platform 1, thus ensuring the stability of the material distribution unit structure. During the material distribution process, when the first material fork 311 and the second material fork 312 move to the placement position of the steel bar 100, the first material fork 311 and the second material fork 312 are synchronously driven to rise, so that the first material fork 311 and the second material fork 312 lift the steel bar 100, and then the first material fork 311 and the second material fork 312 are synchronously driven to move along the supporting platform 1 to above the loading mechanism 3. Then, the first material fork 311 and the second material fork 312 are synchronously driven to descend, so that the steel bar 100 falls onto the movable bracket 21, which facilitates operation. In this embodiment, the first material fork 311 and the second material fork 312 are arranged on opposite sides of the supporting platform 1 to avoid interference with the steel bar 100 on the supporting platform 1.

[0050] In some embodiments, the first and second forks 311, 312 are each provided with a positioning groove 3111 on the side facing the rebar 100. The rebar 100 can be inserted into the positioning groove 3111, thereby enabling the first and second forks 311, 312 to stably support the rebar 100 on the supporting platform 1 and prevent the rebar 100 from separating from the first and second forks 311, 312. In this embodiment, the positioning groove 3111 is configured as a V-shaped groove to facilitate adaptation to the rebar 100. The V-shaped positioning groove 3111 can increase the contact area with the rebar 100 and improve stability when supporting the rebar 100.

[0051] Optionally, both the first guide rail 11 and the second guide rail 12 are electric slides equipped with motors. The motors can be used to drive the first and second forks 311, 312 to slide along the extension direction of the support platform 1, making adjustment very convenient. In some embodiments, the motors of the electric slides are communicatively connected to a control unit of the longitudinal reinforcement placing equipment, so that the control unit automatically controls the movement of the first and second forks 311, 312 along the extension direction of the support platform 1.

[0052] Optionally, the loading mechanism 3 also includes a first driving member 313 and a second driving member. A first connecting plate 111 is slidably provided on the first guide rail 11, and a second connecting plate is slidably provided on the second guide rail 12. The first driving member 313 is provided on the first connecting plate 111, and the output end of the first driving member 313 is connected to the first material fork 311, and is configured to drive the first material fork 311 to rise and fall. The second driving member is provided on the second connecting plate, and the output end of the second driving member is connected to the second material fork 312, and is configured to drive the second material fork 312 to rise and fall. In this embodiment, a first limiting protrusion is provided on the first connecting plate 111, a second limiting protrusion is provided on the second connecting plate, a first guide groove is provided on the first guide rail 11, and a second guide groove is provided on the second guide rail 12. The first limiting protrusion engages and slides with the first guide groove, while the second limiting protrusion engages and slides with the second guide groove, thereby achieving a sliding connection between the first connecting plate 111 and the first guide rail 11, and between the second connecting plate and the second guide rail 12. Optionally, both the first and second driving members are electric cylinders and are communicatively connected to a control unit of the longitudinal reinforcement placing equipment, enabling automated control of the raising and lowering of the first and second forks 311, 312. Electric cylinders offer a compact structure and high precision. In other embodiments, both the first and second driving members 313 and 312 can be pneumatic cylinders, hydraulic cylinders, or other similar cylinders, as long as they can drive the raising and lowering of the first and second forks 311, 312.

[0053] Optionally, the blanking assembly 22 includes a push rod 221. A storage space is provided within the carrying platform 1. A telescopic arm 4 is provided within the storage space. The telescopic arm 4 can extend or retract into the storage space, and the length of the extension or retraction into the storage space is adjustable. The mobile bracket 21 is movably provided on the telescopic arm 4. A guide slope 41 is provided at one end of the telescopic arm 4 near the welding platform 200. The push rod 221 is rotatably provided on the mobile bracket 21. Rotating the push rod 221 can cause the steel bars 100 on the mobile bracket 21 to slide into contact with the guide slope 41, thereby flipping the steel bars 100 on the mobile bracket 21 onto the welding platform 200. Referring to FIG. 5 , in this embodiment, in the initial position, the push rod 221 is arranged horizontally to avoid the steel bars 100 on the mobile bracket 21. During blanking, referring to the orientation shown in Figure 5 , the push rod 221 is driven to rotate upward, causing it to abut against the rebar 100 on the movable support 21. This applies a thrust to the rebar 100, causing it to tilt under the thrust and tend to fall. This thrust then causes the rebar 100 to slide onto the guide ramp 41, allowing it to fall onto the welding platform 200. Rotating the push rod 221 allows the rebar 100 to be flipped onto the welding platform 200, making operation convenient. The guide ramp 41 provides guidance for the rebar 100, ensuring a stable descent. In some embodiments, the blanking assembly 22 further includes a third drive member disposed on the movable support 21. The output end of the third drive member is connected to the push rod 221 and configured to drive the push rod 221 for rotation. Optionally, the third drive member is connected to a control unit of the longitudinal reinforcement placing equipment, enabling automated control of the rotation of the push rod 221. Exemplarily, the third drive member is a motor.

[0054] Because the length of the accommodation space when the telescopic arm 4 is extended or retracted is adjustable, and the mobile bracket 21 is movably disposed on the telescopic arm 4, the end of the mobile bracket 21 can be positioned at any position above the welding platform 200 by adjusting the length of the accommodation space when the telescopic arm 4 is extended or retracted. When the mobile bracket 21 moves to the end of the telescopic arm 4 near the welding platform 200, the rebar 100 is dropped onto the welding platform 200 by the blanking mechanism 2, and the rebar 100 is arranged at a preset position on the welding platform 200. In other words, by varying the length of the accommodation space when the telescopic arm 4 is extended or retracted, the placement of the rebar 100 can be precisely controlled, thereby improving the accuracy of the longitudinal reinforcement layout and ensuring the structural strength of the steel cage.

[0055] Optionally, the mobile support 21 is provided with running wheels, and the telescopic arm 4 is provided with a track along its extension direction. The running wheels engage the track and can slide along the track. In some embodiments, the mobile support 21 is provided with a drive motor, the output end of which is connected to the running wheels and configured to drive the running wheels to rotate, thereby enabling the mobile support 21 to move along the telescopic arm 4. In some embodiments, the drive motor is communicatively connected to a control unit of the longitudinal reinforcement placing equipment, so that the control unit automatically controls the movement of the mobile support 21.

[0056] Exemplarily, the telescopic arm 4 includes a fixed arm, a multi-stage movable arm (e.g., a primary movable arm and a secondary movable arm), and a power unit. The fixed arm is fixed within the accommodation space, the primary movable arm is slidably sleeved within the fixed arm, and the secondary movable arm is slidably sleeved within the primary movable arm, and so on, forming a sleeve-shaped telescopic arm 4. The power unit is configured to provide power to the multi-stage movable arm to drive the multi-stage movable arm to extend and retract step by step. The number of movable arms can be determined according to construction requirements, and the power unit can be a hydraulic cylinder, an electric cylinder, or an electric push rod, etc. The structure of the telescopic arm 4 is conventional in the art.

[0057] In some embodiments, the blanking assembly 22 further includes a buffer plate 222, which is arbitrarily mounted on the mobile support 21. The buffer plate 222 is raised and lowered to support the rebar 100 that falls from the mobile support 21. Referring to Figures 7A to 7D , during blanking, the buffer plate 222 is first driven to rise synchronously, followed by the rotation of the push rod 221, causing the rebar 100 to fall from the mobile support 21 and simultaneously driving the buffer plate 222 downward. During its fall, the rebar 100 remains in contact with the buffer plate 222, ensuring stable contact with the guide ramp 41. When the buffer plate 222 reaches its bottom, the rebar 100 disengages from the guide ramp 41 and falls onto the welding platform 200. The provision of the buffer plate 222 ensures the stability of the rebar 100 as it falls, reducing the impact of the falling rebar 100. This prevents the rebar 100 from damaging the materials on the welding platform 200 or injuring workers on the platform 200, thereby improving construction safety.

[0058] For example, in this embodiment, referring to Figure 6 , a third guide rail 211 extending vertically is provided on one side of the mobile bracket 21, and the buffer plate 222 is slidably connected to the third guide rail 211. Optionally, the third guide rail 211 is a motorized slide rail, which can be driven to raise and lower the buffer plate 222. In some embodiments, the motorized slide rail is connected to the control unit of the longitudinal reinforcement placing equipment, thereby automating the raising and lowering of the buffer plate 222.

[0059] Optionally, the blanking assembly 22 further includes a stopper 223, which includes a first rod 2231 and a second rod 2232 connected and arranged at an angle. The first rod 2231 is rotatably connected to the movable bracket 21. Rotating the first rod 2231 can position the steel bar 100 on the movable bracket 21 between the first rod 2231 and the second rod 2232. The stopper 223 can act as a stopper to prevent the steel bar 100 from falling off the guide inclined surface 41 during the falling process, allowing the steel bar 100 to fall stably. For example, in this embodiment, the first rod 2231 and the second rod 2232 are arranged vertically. Referring to Figures 8A to 8C, the blocking rod 223 can avoid the steel bars 100 on the movable bracket 21 in the initial position. When dropping the material, the blocking rod 223 is first rotated in the second direction (the direction of the arrow in Figure 8A is the second direction). When the blocking rod 223 is rotated until the second rod 2232 is perpendicular to the telescopic arm 4, the push rod 221 can be driven to drop the material (as shown in Figure 8C). At this time, the steel bar 100 is located between the first rod 2231 and the second rod 2232, and the second rod 2232 does not interfere with the guide inclined surface 41. The steel bar 100 on the movable bracket 21 is located within the space enclosed by the first rod 2231 and the second rod 2232, thereby improving the stability of the steel bar 100 in contact with the guide inclined surface 41 when falling. Then, the push rod 221 is rotated to drop the material. In this embodiment, the buffer plate 222 and the baffle rod 223 are respectively arranged on both sides of the movable bracket 21 to avoid interference between the buffer plate 222 and the baffle rod 223, and at the same time avoid interference between the baffle rod 223 and the steel bars 100 on the movable bracket 21 during the transportation of the steel bars 100.

[0060] In some embodiments, the blanking assembly 22 further includes a fourth driving member 224, which is disposed on the movable bracket 21. The output end of the fourth driving member 224 is connected to the first rod 2231. The fourth driving member 224 is configured to drive the first rod 2231 to rotate, thereby driving the blocking rod 223 to rotate. Optionally, the fourth driving member 224 is a motor and is communicatively connected to a control unit of the longitudinal reinforcement placing device.

[0061] In another optional embodiment, the blanking assembly 22 includes a first clamping part and a second clamping part, which are relatively arranged on the mobile bracket 21, and the first clamping part and the second clamping part are both retractable and rotatably connected to the mobile bracket 21. The first clamping part and the second clamping part are both provided with electromagnets, which can adsorb the steel bars 100 on the mobile bracket 21 by energizing the electromagnets. In the initial position, the first clamping part and the second clamping part are arranged vertically upward. When the feeding mechanism 3 transports the steel bars 100 to the top of the mobile bracket 21, the first clamping part and the second clamping part are synchronously driven to rise, so that the first clamping part and the second clamping part lift the steel bars 100 on the supporting platform 1, and at the same time, the electromagnets on the first clamping part and the second clamping part are energized to adsorb the steel bars 100. The mobile support 21 is then driven to move to the end of the telescopic arm 4 near the welding platform 200, and the first and second clamping parts are synchronously driven to rotate, causing them to rotate toward the welding platform 200. The first and second clamping parts are then further driven to extend, causing them to approach the welding platform 200. The electromagnet is then de-energized, and the rebar 100 is transported to the welding platform 200. The energized electromagnet generates magnetism, allowing the first and second clamping parts to stably hold the rebar 100, ensuring the stability of the positional relationship between the rebar 100 and the mobile support 21 and preventing the rebar 100 from separating from the mobile support 21 during transport. When the first and second clamping parts are close to the welding platform 200, the electromagnet is de-energized, allowing the rebar 100 to land stably on the welding platform 200, thereby reducing the impact caused by the rebar 100 falling and improving the accuracy of the rebar 100's placement. In some embodiments, the electromagnet is connected to a control unit of the longitudinal reinforcement placing equipment via a wire so that the control unit can automatically control the power on and off of the electromagnet.

[0062] Exemplarily, two driving motors are arranged on both sides of the movable bracket 21, and the output ends of the two driving motors are connected to rockers one by one. The driving motors are configured to drive the rockers to rotate, and the two electric cylinders are connected to the ends of the two rockers away from the driving motors one by one. The first clamping part and the second clamping part are respectively connected to the output ends of the two electric cylinders, and the first clamping part and the second clamping part are driven to extend and retract by the corresponding electric cylinders.

[0063] Optionally, the material distribution unit further includes a support frame 5 and a drive mechanism 6. Drive mechanism 6 includes a scissor lift arm 61 and a fifth drive member 62. The first end of the scissor lift arm 61 is connected to the load-bearing platform 1, and the second end of the scissor lift arm 61 is connected to the support frame 5. The fifth drive member 62 is configured to provide power to the scissor lift arm 61 to drive the load-bearing platform 1 up and down. The support frame 5 provides stable support for the load-bearing platform 1, thereby ensuring the stability of the material distribution unit. The scissor lift arm 61 can achieve smooth lifting and lowering. Activating the fifth drive member 62 provides power to the scissor lift arm 61, thereby driving the load-bearing platform 1 up and down stably. Exemplarily, the scissor lift arm 61 includes two outer arms 611 and two inner arms 612, arranged crosswise. The outer arms 611 and inner arms 612 are connected at their midpoints by a scissor shaft. The tops of the two outer arms 611 are hinged to the load-bearing platform 1, while the bottoms of the two outer arms 611 are slidably connected to the support frame 5. The tops of the two inner arms 612 are slidably connected to the load-bearing platform 1, while the bottoms of the two inner arms 612 are hinged to the support frame 5. In some embodiments, the fifth drive member 62 is communicatively connected to the control unit of the longitudinal reinforcement placing equipment. Optionally, the fifth drive member 62 is a hydraulic cylinder.

[0064] This embodiment also provides a longitudinal reinforcement distribution device, comprising a welding platform 200, a control unit, and multiple distribution units as described above. The distribution units are spaced apart along a first direction on one side of the welding platform 200. Each distribution unit is communicatively connected to the control unit, which is configured to control the operation of each distribution unit. This longitudinal reinforcement distribution device can transport longitudinal reinforcement to a designated location on the welding platform 200, facilitating ease of operation, saving labor, and improving the accuracy of longitudinal reinforcement distribution. In this embodiment, ten distribution units are provided, with a spacing of 6 meters (m) between adjacent distribution units. The first direction is the length of the welding platform 200. The number and spacing of the distribution units are determined based on actual construction requirements.

[0065] In some embodiments, the control unit may be, for example, a programmable logic controller (PLC).

[0066] In some embodiments, the welding platform 200 is fixed to the ground with anchor bolts. A track is provided on the welding platform 200, extending along the width of the welding platform 200. A welding robot slides on the track to weld a rebar cage. In some embodiments, the welding platform 200 is provided with multiple slots to position the rebar 100.

[0067] This embodiment also provides a longitudinal reinforcement laying method, which uses the longitudinal reinforcement laying equipment described above and includes the following steps:

[0068] S1, placing multiple steel bars 100 on multiple supporting platforms 1 in a one-to-one correspondence, and connecting the multiple steel bars 100 into a longitudinal bar;

[0069] S2, driving the carrying platform 1 to rise and fall to a preset height, and simultaneously driving the plurality of feeding mechanisms 3 to synchronously reciprocate along the extension direction of the carrying platform 1 corresponding to each feeding mechanism 3, and the plurality of detection elements 32 to detect in real time whether the respective carrying platforms 1 corresponding to the detection elements 32 are placed with steel bars 100, and if so, executing step S3;

[0070] S3, driving multiple feeding mechanisms 3 to synchronously move to the placement position of the longitudinal reinforcement, and transporting the longitudinal reinforcement to multiple mobile brackets 21;

[0071] S4, driving the multiple movable supports 21 to move synchronously to transport the longitudinal reinforcement to a preset position above the welding platform 200;

[0072] S5. Synchronously drive the multiple blanking assemblies 22 to flip the longitudinal reinforcement onto the welding platform 200, and drive the multiple movable brackets 21 to synchronously return to the initial position;

[0073] S6. Repeat steps S1 to S5 to complete the layout of the longitudinal reinforcement of the steel cage.

[0074] The longitudinal reinforcement laying equipment and laying method provided in this embodiment have a control unit that can realize automatic control of multiple laying units. During use, construction personnel only need to place multiple steel bars 100 one by one on the supporting platforms 1 of multiple laying units, and connect the multiple steel bars 100 into longitudinal reinforcements. After that, the longitudinal reinforcement laying equipment can be started to transport the longitudinal reinforcements to the preset position of the welding platform 200, saving manpower and reducing the labor intensity of construction personnel.

[0075] In step S1, a construction worker stands between two adjacent material distribution units and connects the steel bars 100 on two adjacent load-bearing platforms 1 together through a steel bar connector to form a longitudinal reinforcement.

[0076] In step S2, the control unit controls the fifth drive assembly of each material distribution unit so that the scissor lift arm 61 drives the carrying platform 1 to a suitable height to adapt to different construction heights. At the same time, the multiple telescopic arms 4 are controlled to extend synchronously to a preset length. The detection element 32 detects in real time whether the steel bars 100 are placed on the carrying platform 1 and provides real-time feedback to the control unit.

[0077] In step S3, when the detection element 32 detects the steel bar 100 on the carrying platform 1, the control unit moves the feeding mechanism 3 to the longitudinal bar position, and then drives the first material fork 311 and the second material fork 312 to rise, so that the first material fork 311 and the second material fork 312 hold up the longitudinal bar. When the feeding mechanism 3 moves to the top of the movable bracket 21, the first material fork 311 and the second material fork 312 are synchronously driven to descend, so that the longitudinal bar falls on the movable bracket 21. At this time, the push rod 221 is located below the longitudinal bar.

[0078] In step S4, the multiple telescopic arms 4 are first synchronously extended to the farthest reinforcement placement position, and then driven to synchronously retract the multiple telescopic arms 4 to a preset length until the reinforcement placement is completed. The preset length is the distance between two adjacent longitudinal bars, which is determined according to the specifications of the steel cage. For example, the preset length is 150 millimeters (mm);

[0079] In step S5, the control unit controls the stopper 223 to rotate, positioning the steel bar 100 between the first rod 2231 and the second rod 2232. The control unit also drives the buffer plate 222 upward so that the push rod 221 can receive the steel bar 100 on the movable bracket 21. The push rod 221 is then driven to rotate, causing it to abut against the longitudinal reinforcement. Under the thrust of the push rod 221, the longitudinal reinforcement can slide against the guide ramp 41. As the longitudinal reinforcement falls, the buffer plate 222 is driven downward, supporting the longitudinal reinforcement and allowing it to descend smoothly. Once the longitudinal reinforcement is free from the guide ramp 41 and the buffer plate 222, it lands at a predetermined position on the welding platform 200. After the blanking is completed, the stopper 223, buffer plate 222, and push rod 221 are driven to return to their original positions. In this embodiment, the lower mesh reinforcement is first laid, while the supporting platform 1 is at its initial position and does not rise. When the lower mesh reinforcement is completed, the supporting platform 1 is driven to rise to a predetermined height to proceed with the mesh reinforcement.

[0080] In one embodiment, the initial position of the movable bracket 21 is located at an end of the telescopic arm 4 close to the carrying platform 1 .
