Description

Technical Field

[0001] This utility model relates to the field of steel strand technology, and in particular to a steel strand guiding device. Background Technology

[0002] Steel strand is a prestressed material made of multiple high-strength steel wires twisted together according to certain rules. It is widely used in civil engineering structures such as bridges, tunnels, and high-rise buildings, possessing advantages such as high load-bearing capacity, excellent tensile strength, and good construction adaptability. In actual construction, the laying out of steel strands is a crucial step in the prestressing tensioning process, and its quality directly affects subsequent tensioning accuracy, structural stress uniformity, and overall construction safety. The steel strand guiding device plays a vital role in the steel strand construction process. As a core component of the laying and threading stages, its structural design and guiding performance have a decisive impact on laying efficiency, operational safety, and construction quality. Especially in this core stage of steel strand laying, existing guiding equipment has gradually revealed a series of obvious limitations and technical problems when handling steel strands with different orientations, spatial layouts, and tensioning requirements.

[0003] Utility model patent CN211920391U discloses a steel strand feeding device that can improve the safety of the steel strand feeding process. It includes a base, a slewing bearing, a chassis, a rotating shaft, six hydraulic cylinders, three iron plates, a turntable, four rollers, and four supports. The device drives the hydraulic cylinders to extend and retract through a hydraulic system, which drives the iron plates to clamp the steel strand and realize the feeding action. At the same time, the angle adjustment function is realized by the connection structure between the turntable and the rotating shaft, which improves the stability and safety of the feeding process.

[0004] While the aforementioned technical solutions enhance the safety and ease of operation of steel strand laying to some extent, they still have many shortcomings in practical applications. In particular, during the steel strand laying process, existing laying devices are not conducive to precisely guiding the laying angle of the steel strand, leading to problems such as strand deviation, knotting, or uneven winding, thus significantly reducing the accuracy of laying and construction quality. Furthermore, in complex construction environments, traditional guiding structures lack flexible adjustment capabilities, making it difficult to adapt to changing wiring path requirements. This increases the workload of manual intervention and repeated adjustments, affecting construction efficiency and potentially causing prestress loss or even structural safety hazards due to guiding errors. Therefore, to address the many shortcomings of existing technologies, there is an urgent need to propose an innovative steel strand guiding device. Utility Model Content

[0005] The purpose of this invention is to provide a steel strand guiding device, which solves the problem that the existing wire laying device is not convenient for accurately guiding the wire laying angle of the steel strand, which leads to problems such as the steel strand being prone to deviation, knotting or uneven winding, thus greatly reducing the accuracy of wire laying and the construction quality.

[0006] To achieve the above objectives, this utility model provides a steel strand guiding device, including a frame, and a bearing rod rotatably connected to one side of the inner side of the frame, and a bearing sleeve is fitted on the bearing rod;

[0007] A second motor is fixedly connected to one side of the outer wall of the frame by bolts, and one end of the bearing rod passes through the side wall of the frame and is connected to the output shaft of the second motor for transmission. A screw is rotatably connected to one side of the inner side of the frame, and a nut seat is screwed onto one end of the screw. A support frame is fixedly connected to the bottom of the nut seat. Rollers are rotatably connected to both sides of the inner side of the support frame through a rotating shaft. A fixed plate is fixedly connected to one side of the support frame, and a push plate is slidably connected to one side of the support frame. A threaded rod is rotatably connected to one side of the push plate through a rotating shaft, and one end of the threaded rod passes through the fixed plate through a threaded groove.

[0008] The first motor is fixedly connected to one side of the outer wall of the frame by bolts, and one end of the screw is rotatably connected to the inner wall of the frame through a rotating shaft, while the other end of the screw is connected to the output shaft of the first motor through a bearing sleeve penetrating the side wall of the frame.

[0009] The top plate is fixedly connected to one side of the frame, and a slider is fixedly connected to the top of the nut seat. The slider is slidably connected to the top plate through a groove.

[0010] The upper and lower sides of the push plate are fixedly connected to sliding blocks, and the sliding blocks are slidably connected to one side of the support frame through sliding grooves.

[0011] The frame has two stabilizing rods on one inner side, and both ends of the two stabilizing rods are rotatably connected to the inner wall of the frame through a pivot, and there is a certain gap between the two stabilizing rods.

[0012] One end of the support rod is detachably connected to a limit plate via bolts, and the other end of the support rod passes through the side wall of the frame via a bearing sleeve.

[0013] This utility model's steel strand guiding device, through a linkage structure between a screw and a nut seat driven by a first motor, achieves automatic displacement adjustment of the support frame and roller assembly. It can dynamically adjust the exit position of the steel strand according to construction needs, effectively improving the guiding accuracy and automation level of the laying process. The two rollers inside the support frame have a rotatable structure, which not only reduces the frictional resistance of the steel strand during laying but also accommodates slight swaying of the steel strand during operation, avoiding wear or displacement caused by rigid contact and improving laying stability. Furthermore, a fine-tuning mechanism consisting of a fixed plate, a push plate, and a threaded rod is used. The structure allows operators to make precise adjustments to the local direction of the steel strands, compensating for potential errors in long-distance guidance and further improving the accuracy of the laying. In addition, the entire guiding device has a compact structure and reasonable layout, with good spatial adaptability, and is especially suitable for multi-angle and multi-path guidance needs in complex construction environments. It effectively reduces the frequency of manual intervention, reduces the workload of repeated adjustments, and improves construction efficiency. At the same time, because the guiding path is more stable and smooth, it also significantly reduces the probability of abnormal situations such as knotting, uneven winding, and deviation from the track during the laying process of the steel strands, thereby ensuring the quality of prestressing tensioning and construction safety.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 .

[0023] A steel strand guiding device includes a frame 1, and a bearing rod 2 is rotatably connected to one side of the inner side of the frame 1, and a bearing sleeve 3 is sleeved on the bearing rod 2.

[0024] A second motor 11 is fixedly connected to one side of the outer wall of the frame 1 by bolts, and one end of the bearing rod 2 passes through the side wall of the frame 1 and is connected to the output shaft of the second motor 11 for transmission. A screw 6 is rotatably connected to one side of the inner side of the frame 1, and a nut seat 7 is threadedly connected to one end of the screw 6. A support frame 12 is fixedly connected to the bottom of the nut seat 7. Rollers 18 are rotatably connected to both sides of the inner side of the support frame 12 through a rotating shaft. A fixing plate 13 is fixedly connected to one side of the support frame 12, and a push plate 14 is slidably connected to one side of the support frame 12. A threaded rod 17 is rotatably connected to one side of the push plate 14 through a rotating shaft, and one end of the threaded rod 17 passes through the fixing plate 13 through a threaded groove.

[0025] First, the steel strand to be laid is wound onto the bearing sleeve 3, and the bearing sleeve 3 is installed on the bearing rod 2. The second motor 11 is started, driving the bearing rod 2 to rotate, achieving stable laying of the steel strand. Simultaneously, a screw 6 is installed on one side of the inner side of the frame 1. One end of the screw 6 is connected to the first motor 10 via a transmission mechanism. When the first motor 10 starts, the screw 6 rotates, causing the nut seat 7, which is threadedly connected to it, to move axially along the screw 6, thereby causing the support frame 12 to slide along the frame 1. Both inner sides of the support frame 12 are... Rollers 18 are rotatably connected via a pivot, and the steel strand passes between the two rollers 18, serving as a limit and guide. In addition, a fixed plate 13 is provided on one side of the support frame 12, and a push plate 14 is slidably connected on the other side. A threaded rod 17 is rotatably connected to one side of the push plate 14 via a pivot. One end of the threaded rod 17 passes through the fixed plate 13 through a threaded groove. When it is necessary to make local angle fine adjustments to the steel strand, the push plate 14 can be moved back and forth by adjusting the threaded rod 17, thereby changing the outgoing direction of the steel strand and achieving short-distance, high-precision guiding control.

[0026] Furthermore, a first motor 10 is fixedly connected to one side of the outer wall of the frame 1 by bolts, and one end of the screw 6 is rotatably connected to the inner wall of the frame 1 through a rotating shaft. The other end of the screw 6 is connected to the output shaft of the first motor 10 through a bearing sleeve penetrating the side wall of the frame 1. After the first motor 10 is started, the screw 6 can be driven to rotate stably, which drives the nut seat 7 to move along the axial direction of the screw 6, thereby realizing the linear displacement adjustment function of the support frame 12 and roller 18 assembly, achieving the effect of improving the automation level and adjustment accuracy of the guiding device.

[0027] Furthermore, a top plate 5 is fixedly connected to one side of the top of the frame 1, and a slider 8 is fixedly connected to the top of the nut seat 7. The slider 8 is slidably connected to the top plate 5 through the slide groove 9. As the nut seat 7 moves with the screw 6, the slider 8 slides synchronously along the slide groove 9, which plays a role in assisting guidance and enhancing structural stability. This effectively prevents the nut seat 7 from swaying or getting stuck during operation, thereby improving the smooth operation of the guide assembly and extending its service life.

[0028] Furthermore, sliding blocks 15 are fixedly connected to both the upper and lower sides of the push plate 14, and the sliding blocks 15 are slidably connected to one side of the support frame 12 through the sliding groove 16. When making local angle fine adjustments to the steel strand, the sliding blocks 15 slide synchronously along the sliding groove 16 while the push plate 14 is moved back and forth by pushing the threaded rod 17, ensuring that the movement trajectory of the push plate 14 is stable and reliable, improving the accuracy and controllability of the fine adjustment operation, and achieving the effect of enhancing short-distance guiding adjustment capability and improving wire feeding quality.

[0029] Furthermore, two stabilizing rods 19 are provided on one inner side of the frame 1, and both ends of the two stabilizing rods 19 are rotatably connected to the inner wall of the frame 1 through a pivot. There is a certain gap between the two stabilizing rods 19, which allows the support frame 12 to pass smoothly during its movement. At the same time, the stabilizing rods 19 act as reinforcing ribs for the entire frame 1 structure, improving the overall rigidity and resistance to deformation, thereby enhancing the structural strength and load-bearing stability of the guiding device.

[0030] Furthermore, a limiting plate 4 is detachably connected to one end of the bearing rod 2 by bolts, and the other end of the bearing rod 2 passes through the side wall of the frame 1 through a bearing sleeve. When installing or replacing the bearing sleeve 3, the bearing sleeve 3 can be removed from the bearing rod 2 by disassembling the limiting plate 4, which facilitates maintenance and replacement of bearing sleeves 3 of different specifications, improves the versatility and flexibility of the equipment, and achieves the effect of improving the adaptability of the equipment and reducing maintenance costs.

[0031] In summary:

[0032] First, the steel strand to be laid is wound around the bearing sleeve 3, and the bearing sleeve 3 is installed on the bearing rod 2. One end of the bearing rod 2 passes through the side wall of the frame 1 through the bearing sleeve, and is detachably connected to the limit plate 4 by bolts to limit the bearing sleeve 3 axially and prevent it from shifting or falling off during the laying process. Then, the second motor 11 is started, and its output shaft drives the bearing rod 2 to rotate through the transmission mechanism, thereby driving the bearing sleeve 3 to rotate synchronously, so as to realize the stable laying operation of the steel strand. Meanwhile, a screw 6 is rotatably connected to one side of the inner side of the frame 1. One end of the screw 6 is rotatably connected to the inner wall of the frame 1 through a rotating shaft, and the other end passes through the side wall of the frame 1 through a bearing sleeve and is connected to the output shaft of the first motor 10. Under the drive of the first motor 10, the screw 6 rotates stably, driving the nut seat 7, which is screwed to it, to move axially along the screw 6. A slider 8 is fixedly connected to the top of the nut seat 7. The slider 8 is slidably connected to the top plate 5 fixed to the top of the frame 1 through a sliding groove 9. During the sliding of the slider 8 along the sliding groove 9, it plays a role in assisting guidance and enhancing the stability of the structure, ensuring that the nut seat 7 will not wobble or jam during movement, and improving the running accuracy and service life of the guiding component. A support frame 12 is fixedly connected to the bottom of the nut seat 7. Rollers 18 are rotatably connected to both sides of the inner side of the support frame 12 via a rotating shaft. The steel strand passes between the two rollers 18. Under the rolling action of the rollers 18, the frictional resistance between the steel strand and the guide component is effectively reduced, while the function of limiting and stabilizing the steel strand is realized. A fixed plate 13 is fixedly connected to one side of the support frame 12, and a push plate 14 is slidably connected to the other side. Sliding blocks 15 are fixedly connected to the upper and lower parts of the push plate 14. The sliding blocks 15 are slidably connected to one side of the support frame 12 through the sliding groove 16. When it is necessary to make a fine adjustment to the local angle of the steel strand, the operator can rotate the threaded rod 17 to move the push plate 14 back and forth, thereby changing the output direction of the steel strand, realizing short-distance, high-precision guiding control, and further improving the accuracy and adaptability of the wire laying. In addition, two stabilizing rods 19 are provided on one side of the inner side of the frame 1. Both ends of the rods are rotatably connected to the inner wall of the frame 1 through a pivot, and a certain gap is maintained between the two stabilizing rods 19 to allow the support frame 12 to pass smoothly. This structure not only does not affect the normal operation of the support frame 12, but also effectively enhances the overall rigidity and deformation resistance of the frame 1, and improves the load-bearing stability and structural strength of the guide device in high-intensity construction environments.The first motor 10 drives the screw 6 to move the nut seat 7 and support frame 12, realizing the automatic adjustment function of the guide position during the steel strand laying process, improving the guiding accuracy and automation level; the cooperation structure of the slider 8 and the slide groove 9 enhances the running stability of the guide assembly and extends the service life of the equipment; the setting of the roller 18 reduces the friction loss of the steel strand during the guiding process and improves the smoothness of laying; the push plate 14 combined with the sliding block 15 and the threaded rod 17 fine adjustment structure allows the operator to flexibly adjust the local direction of the steel strand, make up for possible errors in long-distance guidance, and improve the laying quality; the addition of the stabilizing rod 19 further enhances the structural strength of the frame 1 and improves the adaptability of the equipment in complex construction environments; the detachable connection structure of the bearing rod 2 and the limiting plate 4 facilitates the installation, disassembly and replacement of bearing sleeves 3 of different specifications, improves the versatility and maintenance convenience of the equipment, and reduces the operating cost. The overall device has a reasonable structure, high guiding accuracy, flexible adjustment, and stable operation. It can effectively solve the problems of inaccurate steel strand laying guidance, inconvenient operation, and poor adaptability in existing technologies. It meets the urgent needs of modern civil engineering for efficient, high-precision, and safe guiding equipment and has good engineering application prospects and promotion value.
