Description

Technical Field

[0001] The present invention relates to the technical field of civil engineering, and in particular to a device for manufacturing continuous stirrups of reinforced photovoltaic cast-in-place piles and a method for using the same. Background Art

[0002] As a critical component of photovoltaic power station infrastructure, the quality of photovoltaic piles is directly impacting the stability and safety of the entire plant. The quality and efficiency of the stirrups in these piles play a crucial role in their performance. Traditionally, the production of stirrups for photovoltaic piles relies heavily on manual labor. Workers must manually bend and cut the steel bars, a labor-intensive process that not only consumes significant labor and incurs high labor intensity, but also leads to extremely low production efficiency. In large-scale photovoltaic power station construction, manual stirrup production is far from meeting project schedule requirements, severely hindering project progress. Regarding production accuracy, manual labor is affected by factors such as worker skill and fatigue, making it difficult to ensure high stirrup dimensional accuracy and consistent shape. Large deviations in stirrup dimensional structure can lead to structural irregularities in the pile reinforcement cage, compromising its bond with the concrete and weakening the pile's load-bearing capacity, posing a threat to the long-term stable operation of the photovoltaic power station.

[0003] With the development of automation technology, some automated stirrup production equipment has emerged. However, these devices generally suffer from complex structures. The numerous and complex mechanical structures and control systems not only increase the manufacturing and procurement costs of the equipment, but also make it difficult for the various components to work together during use, making them prone to failure. Once the equipment fails, repairs are difficult, costly, and time-consuming, leading to production stagnation and significant losses to the project. Furthermore, some existing automated stirrup production equipment fails to fully consider the special needs of photovoltaic projects when producing stirrups for photovoltaic cast-in-place pile reinforcement. For example, the construction site of a photovoltaic power station may be complex, requiring equipment to have a certain degree of adaptability. Photovoltaic cast-in-place piles also require special specifications and quality requirements for stirrups, which existing equipment cannot fully meet. There is an urgent need to develop a device and method specifically for the production of continuous stirrups for photovoltaic cast-in-place pile reinforcement to address the many problems currently existing in the production of stirrups for photovoltaic cast-in-place pile reinforcement and promote the high-quality development of photovoltaic power station construction.

[0012] According to another object of the present invention, the present invention provides a method for using the above-mentioned photovoltaic cast-in-place pile continuous stirrup manufacturing device, comprising the following steps: S1. Equipment preparation: Check the operating status of the motor and cylinder power components, check the connection stability of the transmission chain and gear transmission components, and check the surface smoothness of the bending mold cavity and bending guide roller; S2. Steel bar transportation and bending: The motor is started to drive the conveying roller to rotate synchronously to convey the steel bar, and the bending guide roller is driven to rotate through the transmission chain, so that the steel bar is bent along the bending mold cavity.

[0022] Example 1 like Figure 1-Figure 7 As shown, a photovoltaic cast-in-place pile steel bar continuous stirrup production device includes a workbench 1, a bending mold 2 is provided on the top of the workbench 1, a curved cavity is formed inside the bending mold 2, and a steel bar 3 is slidably inserted into the cavity, and conveying rollers 4 are symmetrically provided on both sides of the ends of the steel bar 3. The bottom centers of the conveying rollers 4 are coaxially provided with a rotating shaft 5. The outer peripheral surface of the lower portion of the rotating shaft 5 is rotatably sleeved with a spur gear 24. The two spur gears 24 are meshed with each other. A motor 6 is provided at the bottom of the workbench 1, and the output shaft of the motor 6 is coaxially connected to the end of one of the rotating shafts 5. like Figure 2 and Figure 3 As shown, a plurality of bending guide rollers 29 are evenly distributed on the inner side of the bending mold 2. A driven rod 28 is coaxially provided at the bottom center of each bending guide roller 29. A transmission sprocket 7 is sleeved on the bottom end of the driven rod 28 and the bottom end of the rotating shaft 5. The transmission sprocket 7 is sleeved on the same transmission chain 8. like Figure 5As shown, a transmission rod 10 is coaxially provided on the top of one of the conveying rollers 4, and a first bevel gear 11 is coaxially provided on the top of the transmission rod 10. A second bevel gear 12 is meshed with a first bevel gear 12 on one side of the first bevel gear 11, and a worm 14 is coaxially provided on the second bevel gear 12. The worm 14 is rotatably sleeved on the shaft seat 13, and a worm wheel 15 is meshed with the end of the worm 14. A rotating rod 16 is inserted into the center of the worm wheel 15, and the end of the rotating rod 16 is rotatably sleeved on the support seat 18. A cam 17 is sleeved on the outer circumference of the rotating rod 16 near the position between the support seat 18 and the worm wheel 15, and a cutter 19 is provided below the cam 17. The cutter 19 is slidably embedded in the cavity at the end of the bending mold 2.

[0023] Specifically, cross bars 20 are symmetrically provided at both ends of the cutter 19, and slide bars 21 are provided at the bottom of the cross bars 20. The slide bars 21 are slidably sleeved on the brackets 23, and the brackets 23 are fixed to the top of the workbench 1; the slide bars 21 are sleeved with top springs 22 at positions between the cross bars 20 and the brackets 23; like Figure 6 As shown, a tensioning sprocket 9 is further provided on the outer side of the transmission chain 8 for controlling the transmission angle of the transmission sprocket 7 and assisting in the tensioning of the transmission chain 8 .

[0024] like Figure 1 and Figure 7 As shown, a cylinder 25 is provided on the top of the workbench 1 at the center of the bending mold 2, and a plurality of connecting rods 26 are provided on the top of the cylinder 25. The ends of the connecting rods 26 are provided with L-shaped support rods 27, and the lower tail ends of the L-shaped support rods 27 are slidably embedded in the bending mold 2. The cylinder 25 is a cylinder with an adjustable stroke to meet the requirements for the ejection height of the L-shaped support rods 27 when making stirrups of different sizes.

[0025] The inner wall of the cavity of the bending die 2 is provided with a wear-resistant coating to reduce wear on the inner wall of the cavity by the rebar 3 during the bending process, thereby extending the service life of the bending die 2. The motor 6 is a variable frequency motor, and the conveying speed of the rebar 3 can be controlled by adjusting the motor speed, thereby meeting different production efficiency and stirrup production accuracy requirements.

[0026] The method for using the photovoltaic cast-in-place pile continuous stirrup manufacturing device of the present invention comprises the following steps: Carry out a comprehensive inspection of all components of the production device to check whether the appearance of the motor 6 is damaged, whether the wiring is firm, and whether it can operate normally after power is turned on; check the sealing performance of the cylinder 25 to ensure that there is no air leakage and whether the telescopic movement of the cylinder is smooth; check whether the transmission chain 8 is loose or worn, and whether the meshing of the chain links and sprocket teeth is good; check whether the connection of transmission components such as gears and worm gears is firm and whether the surface is damaged; check whether the cavity of the bending mold 2 and the surface of the bending guide roller 29 are smooth, and whether there are any protrusions or depressions that may affect the bending of the steel bar.

[0027] Prepare the steel bars to be processed 3, ensuring that the specifications of the steel bars meet the requirements for stirrup production and that the steel bars have no defects such as severe rust and cracks on their surface; Place the prepared steel bar 3 between the two conveying rollers 4 so that the end of the steel bar 3 is accurately aligned with the cavity entrance of the bending die 2 to ensure that the steel bar can smoothly enter the bending die 2 for bending during the conveying process; Start the motor 6, which drives the rotating shaft 5 connected thereto to rotate. Through the mutual engagement of the spur gears 24, the two conveying rollers 4 rotate synchronously, thereby smoothly conveying the steel bar 3 into the bending mold 2; As the conveying roller 4 rotates, the transmission sprocket 7 and the transmission chain 8 at the bottom of the rotating shaft 5 drive the transmission sprocket 7 at the bottom of the driven rod 28 at the bottom of the bending guide roller 29 to rotate, so that the bending guide roller 29 rotates synchronously; after entering the bending mold 2, the steel bar 3 is gradually bent along the cavity of the bending mold 2 under the action of the rotating bending guide roller 29; During this process, the tensioning sprocket 9 controls the transmission angle of the transmission sprocket 7 in real time and adjusts the tension of the transmission chain 8 to ensure the stability of the steel bar transportation and bending process, and avoid inaccurate steel bar bending shape due to unstable transmission.

[0028] As the conveying roller 4 rotates, the transmission rod 10 on the top rotates synchronously, driving the first bevel gear 11 to rotate. The first bevel gear 11 meshes with the second bevel gear 12, driving the second bevel gear 12 and the coaxial worm 14 to rotate. The worm 14 meshes with the worm wheel 15, driving the worm wheel 15 and the rotating rod 16 to rotate, and the cam 17 on the rotating rod 16 rotates accordingly; When the cam 17 rotates to a specific position, the raised part of the cam 17 pushes the cutter 19 to slide inside the cavity at the end of the bending mold 2, thereby cutting off the stirrups that have been bent and formed; during the action of the cutter 19, the slide bars 21 at the bottom of the cross bars 20 at both ends of the cutter 19 slide in the bracket 23, and the top spring 22 on the slide bar 21 plays a role in buffering the impact force of the cutting action of the cutter 19. At the same time, after the cam 17 rotates away from the pushing position, the auxiliary cutter 19 is reset to prepare for the next cutting action.

[0029] After the stirrups are cut into finished products, the cylinder 25 is activated. Cylinder 25, according to the pre-adjusted stroke, drives the L-shaped support rod 27 upward via the connecting rod 26. The lower end of the L-shaped support rod 27 slides inside the bending die 2, quickly and smoothly removing the finished steel bars from the bending die 2. After the finished stirrups are removed, they are collected and sorted using a suitable collection tool, such as a basket. The collected stirrups can be further sorted, bundled, and other operations based on production needs.

[0030] The present invention realizes the continuous conveying and bending of steel bars by driving the conveying roller and the bending guide roller to work in coordination through the motor. At the same time, the cooperation of the cutter and the discharging mechanism can quickly complete the cutting and discharging of the stirrups, greatly improving the production efficiency of the stirrups and meeting the needs of large-scale photovoltaic cast-in-place pile construction.

[0031] The specific cavity design of the bending die and the equally spaced distribution of the bending guide rollers ensure that the rebar is accurately formed to the desired shape during the bending process. Furthermore, the synchronized rotation of the conveyor rollers and the precise control of the cutting mechanism ensure the consistency and accuracy of the stirrup dimensions, improving the quality of the photovoltaic cast-in-place piles.

[0032] The adjustable-stroke cylinder of this invention can adapt to the production requirements of stirrups of different sizes. The variable-frequency motor can adjust the steel bar delivery speed according to actual production conditions, enhancing the device's adaptability to different production requirements. The wear-resistant coating on the inner wall of the bending mold cavity extends the mold's service life and reduces long-term operating costs.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
