Description

Technical Field

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

[0002] In bridge construction, heavy steel beams are typically moved into place using a dragging method. This involves placing a slider at the bottom of the beam and anchoring steel strands to it. The other end of the strands is anchored to a hydraulic cylinder cavity. Continuous jacks are used to pull the strands, causing them to contract and thus dragging the slider longitudinally, positioning the beam. However, this dragging process relies on the contraction of the steel strands. During this contraction, the strands easily become entangled or knotted, reducing the beam's transport efficiency and impacting subsequent construction.

[0003] To ensure the smooth progress of construction operations, a steel strand combing device has been proposed, comprising a main rod, comb teeth, and comb handle. Multiple comb teeth are evenly arranged axially on the outer periphery of the main rod. The main rod is rotatably connected to the comb handle, and a motor is installed inside the comb handle. After the motor is started, the main rod can rotate relative to the comb handle, so that the comb teeth can comb the steel strand placed on it.

[0004] However, in the above-mentioned steel strand combing device, the connection between the main rod and the comb handle needs to bear the weight of the main rod itself and the steel strand at the same time, and also needs to transmit the torque of the motor. The load it bears is large, and it is easy to break after long-term use, causing the main rod to separate from the comb handle and causing a safety accident. Utility Model Content

[0005] The purpose of this utility model is to provide a steel strand guiding device that can improve the support strength and guiding reliability of the steel strand, and ensure the smooth progress of the construction process.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model proposes a steel strand guiding device, comprising:

[0008] The support base includes a first support member and a second support member that are parallel to each other and spaced apart;

[0009] The support assembly includes a first support column and a second support column. The first support column is disposed above and connected to the first support member, and the second support column is disposed above and connected to the second support member.

[0010] The dredging component includes a cylinder and an installation shaft. The installation shaft is installed through the cylinder along its axial direction. One end of the installation shaft is connected to a first support column, and the other end is connected to a second support column. The cylinder can rotate around its own axis. Multiple comb teeth are arranged at intervals along the axial direction of the cylinder on its outer periphery. Each comb tooth extends outward along the radial direction of the cylinder, and a dredging space with steel strands is formed between adjacent comb teeth.

[0011] Optionally, the cylinder body is provided with multiple locking holes spaced apart along the axial direction. Each comb tooth can be detachably inserted into any locking hole and can be locked in place with the locking hole. At most one comb tooth is provided in each locking hole.

[0012] Specifically, the steel strand guiding device also includes limiting rings, with limiting rings fitted at both ends of the cylinder along its own axial direction.

[0013] More specifically, the limiting ring is provided with an elastic buffer on the side of the cylinder near the comb teeth along the axial direction of the cylinder.

[0014] Optionally, the end of the comb teeth away from the barrel is tapered.

[0015] Optionally, the steel strand guiding device further includes at least two connectors, which are spaced apart along the length of the first bearing member. One end of each connector is fixed to the first bearing member, and the other end is fixed to the second bearing member.

[0016] Specifically, each connector is equipped with a self-locking caster wheel at its bottom.

[0017] Optionally, the support assembly further includes a support reinforcement member, which is set at an angle to the first support column, with a first end of the support reinforcement member connected to the first support column and a second end of the support reinforcement member connected to the first carrier member.

[0018] Optionally, both the first and second load-bearing components are I-beams.

[0019] For example, both the first support column and the second support column are made of steel.

[0020] The beneficial effects of this utility model are:

[0021] This invention proposes a steel strand guiding device. Multiple comb teeth are arranged on the outer periphery of the cylinder, with adjacent comb teeth forming a guiding space for the steel strands to pass through. When the cylinder rotates around its own axis, multiple steel strands passing through the cylinder can enter different guiding spaces under the action of the multiple comb teeth, and continue to contract along their original path under the guidance and constraint of the guiding space. The multiple comb teeth can adjust the spacing between the multiple steel strands, reducing entanglement or knotting during continuous contraction, ensuring the smooth progress of construction operations that rely on steel strand contraction. One end of the mounting shaft is connected to a first support column, which is connected to a first bearing member. The other end of the mounting shaft is connected to a second support column, which is connected to a second bearing member. The support components and the bearing base can work together to provide stable support for the guiding components, improving the support strength of the guiding components and ensuring the reliability and smooth progress of the guiding process.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] When using a drag-and-pull method to jack up large-tonnage steel beams, a slider is typically installed at the bottom of the beam, with steel strands anchored on it. The other end of the steel strands is anchored to a hydraulic cylinder cavity. Continuous jacks are used to pull the steel strands, causing them to contract and thus dragging the slider longitudinally, thereby positioning the steel beam. This dragging process relies on the contraction of the steel strands. During contraction, the strands easily become entangled or knotted, reducing the transport efficiency of the steel beam and affecting subsequent construction.

[0035] like Figures 1-2As shown, this embodiment provides a steel strand guiding device, including a bearing base 1, a support assembly 2, and a guiding assembly 3. The bearing base 1 includes a first bearing member 11 and a second bearing member 12 that are parallel to each other and spaced apart. The support assembly 2 includes a first support column 21 and a second support column 22. The first support column 21 is disposed above the first bearing member 11 and connected to the first bearing member 11, and the second support column 22 is disposed above the second bearing member 12 and connected to the second bearing member 12. The guiding assembly 3 includes a cylinder 31 and a mounting shaft 32. The mounting shaft 32 is disposed through the cylinder 31 along its axial direction. One end of the mounting shaft 32 is connected to the first support column 21, and the other end is connected to the second support column 22. The cylinder 31 can rotate around its own axis. Multiple comb teeth 311 are spaced apart along the axial direction of the cylinder 31 on its outer periphery. Each comb tooth 311 extends outward along the radial direction of the cylinder 31, and a guiding space for the steel strand is formed between adjacent comb teeth 311. It is understandable that the steel strand guiding device is installed on the contraction path of multiple steel strands.

[0036] In this embodiment, multiple comb teeth 311 are provided on the outer periphery of the cylinder 31. Adjacent comb teeth 311 form a guiding space for the steel strands to pass through. When the cylinder 31 rotates around its own axis, the multiple steel strands passing through the cylinder 31 can enter different guiding spaces under the action of the multiple comb teeth 311, and continue to contract along the original path under the guidance and constraint of the guiding space. The multiple comb teeth 311 can adjust the spacing of the multiple steel strands, reduce the entanglement or knotting phenomenon generated by the multiple steel strands during the continuous contraction process, and ensure the smooth progress of construction operations that rely on the contraction of steel strands. One end of the mounting shaft 32 is connected to the first support column 21, and the first support column 21 is connected to the first bearing member 11. The other end of the mounting shaft 32 is connected to the second support column 22, and the second support column 22 is connected to the second bearing member 12. The support component 2 and the bearing base 1 can work together to provide a stable support effect for the guiding component 3, improve the support strength of the guiding component 3, and ensure the reliability of the guiding and the smooth progress of the guiding process.

[0037] Optionally, one end of the mounting shaft 32 is fixedly connected to the first support column 21, and the other end is fixedly connected to the second support column 22. The cylinder 31 is rotatably connected to the mounting shaft 32, allowing the cylinder 31 to rotate around the mounting shaft 32 with strong rotational stability. In other embodiments, the tops of both the first support column 21 and the second support column 22 are provided with bearings and their mounting seats. One end of the mounting shaft 32 is rotatably connected to the bearing at the top of the first support column 21, and the other end is rotatably connected to the bearing at the upper part of the second support column 22. The cylinder 31 and the mounting shaft 32 can rotate synchronously relative to the first support column 21 and the second support column 22, reducing the wear between components during the dredging process. It is understood that a drive motor is connected to the end of the mounting shaft 32 protruding from the cylinder 31, and the drive motor is used to realize the rotation process of the cylinder 31 and the mounting shaft 32.

[0038] For example, the end of the comb tooth 311 away from the cylinder 31 is tapered. The tapered end of the comb tooth 311 can provide guidance for the steel strand to enter the guide space, reduce the difficulty of the steel strand entering the guide space, and also reduce the wear of the steel strand and the comb tooth 311 during the steel strand guide process.

[0039] To improve the guiding efficiency and effect of the steel strand guiding device, such as Figure 1 and Figure 2 As shown, the outer periphery of the cylinder 31 may be provided with multiple tooth groups spaced apart along the circumference of the cylinder 31. Each tooth group contains multiple comb teeth 311 that are parallel to each other and spaced apart along the axial direction of the cylinder 31. It can be understood that the number and position of the comb teeth 311 in the multiple tooth groups correspond one-to-one.

[0040] Specifically, the steel strand guiding device may further include limiting retaining rings 4, with limiting retaining rings 4 fitted at both ends of the cylinder 31 along its own axial direction. It is understood that the length covered by the limiting retaining rings 4 in the radial direction of the cylinder 31 is greater than the length covered by the comb teeth 311 arranged in the radial direction of the cylinder 31. Fitting the limiting retaining rings 4 at both ends of the cylinder 31 along its own axial direction can limit the displacement of the steel strand along the axial direction of the cylinder 31 during guiding, ensuring the guiding effect and safety of the guiding component 3 on the steel strand.

[0041] More specifically, the limiting ring 4 is provided with an elastic buffer on the side of the cylinder 31 near the comb teeth 311 along the axial direction. The elastic buffer avoids rigid collisions between the steel strand and the limiting ring 4 during the dredging process, reduces the wear on the steel strand and the ring, and extends the service life of the limiting ring 4.

[0042] Preferably, the cylinder 31 has multiple locking holes spaced apart along the axial direction. Each comb tooth 311 is detachably inserted into any locking hole and can be locked in place with the locking hole. At most one comb tooth 311 is provided in each locking hole. The detachable insertion of each comb tooth 311 into any locking hole allows the spacing between adjacent comb teeth 311 on the outer periphery of the cylinder 31 to be adjustable, thereby meeting the requirements of guiding steel strands of different diameters and improving the versatility of the steel strand guiding device. For example, the locking hole can be a threaded hole, and the end of the comb tooth 311 near the outer periphery of the cylinder 31 is machined with a thread that engages with the threaded hole.

[0043] Optionally, the steel strand guiding device further includes at least two connectors 5, which are spaced apart along the length of the first bearing member 11. One end of each connector 5 is fixed to the first bearing member 11, and the other end is fixed to the second bearing member 12, so as to enhance the structural integrity of the first bearing member 11 and the second bearing member 12 and improve the bearing effect of the bearing base 1.

[0044] Specifically, each connector 5 is equipped with a self-locking caster wheel at its bottom. The caster wheel improves the mobility of the steel strand guiding device and reduces the labor intensity of construction workers during its movement. The self-locking caster wheel enhances the positional accuracy of the bearing base 1 and support component 2 during steel strand guiding, ensuring stable operation.

[0045] Optionally, such as Figure 1 and Figure 2 As shown, the support component 2 also includes a support reinforcement 23, which is set at an angle to the first support column 21. The first end of the support reinforcement 23 is connected to the first support column 21, and the second end is connected to the first carrier member 11. The support reinforcement 23 enhances the connection strength between the first support column 21 and the first carrier member 11, thereby strengthening the support effect of the support component 2 on the drainage component 3. In this embodiment, a support reinforcement 23 is provided between the first support column 21 and the first carrier member 11, and also between the first support column 21 and the second carrier member 12, to enhance the overall structural strength of the support component 2 and further improve its support effect on the drainage component 3. For example, the first support column 21, the second support column 22, and the support reinforcement 23 are all made of steel, resulting in high support strength for the support component 2. The first support column 21, the second support column 22, and the support reinforcement 23 can all be steel pipes.

[0046] In this embodiment, both the first bearing member 11 and the second bearing member 12 are I-beams, which have strong shear resistance and good load-bearing effect. Compared with solid steel of the same height, I-beams are lighter in weight, which facilitates the installation or relocation of the steel strand guiding device.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
