Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering, in particular to a cable tower annular prestressed integral rapid positioning device. Background Art

[0002] Circumferential prestressing technology is a technology widely used in civil engineering structures, especially in bridge construction, where it has significant advantages. This technology improves the crack resistance and rigidity of the structure by applying circumferential tension in the components, and can effectively prevent and reduce the occurrence of cracks. Even in the case of concrete cracks, circumferential prestressing can reduce the expansion of cracks and reduce the impact of cracks on structural safety. In addition, circumferential prestressing technology helps save materials, reduce the deadweight of components, and at the same time reduce vertical shear force and principal tensile stress, and enhance the fatigue resistance of components. These advantages make this technology an important means to improve the overall performance of the structure.

[0003] In bridge construction, circumferential prestressing technology increases the connection strength between components by applying tensile force, avoiding the generation of cracks, improving the overall project quality, and to a certain extent reducing construction costs. However, despite the many advantages of circumferential prestressing technology, how to ensure the accuracy of the prestressing application position remains a key technical issue in construction. If the prestressing position is inaccurate, it will not only affect the effective transmission of prestress, but may also lead to uneven stress distribution in the components, reducing the safety and service life of the structure. Therefore, ensuring accurate control of the prestressing position is an important challenge in the application of circumferential prestressing technology in actual engineering. Utility Model Content

[0004] The purpose of the utility model is to provide a cable tower annular prestressed integral rapid positioning device to solve the problem of inaccurate prestressed position in the prior art, which not only affects the effective transmission of prestressed stress, but also may lead to uneven stress distribution of components, reducing the safety and service life of the structure.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device for quickly positioning the annular prestressed structure of a cable tower, comprising:

[0006] Support mechanism;

[0007] A plurality of guide mechanisms, wherein the guide mechanisms are arranged on the support mechanism;

[0008] A fixed rack is provided on a guide mechanism, the fixed rack being movable along the guide mechanism, and the guide mechanism being used to support and guide the fixed rack;

[0009] The restraint mechanism is arranged on the fixed bent frame and is used to accommodate and fix the prestressed steel strands.

[0010] Preferably, the supporting mechanism includes main reinforcement.

[0011] Preferably, the guide mechanism includes a guide rail, and the guide rail is detachably arranged on the top of the main rib.

[0012] Preferably, the fixed rack is slidably connected to the top of the guide rail.

[0013] Preferably, the restraint mechanism includes a plurality of slots, and the slots are fixedly connected to the top of the fixed rack.

[0014] Preferably, the slots are distributed at equal intervals on the top of the fixed rack.

[0015] It can be seen from the above technical solution that the utility model has the following beneficial effects:

[0016] The overall rapid positioning device for the annular prestressed steel bundle of the cable tower can realize the precise positioning of the prestressed steel bundle in the cable tower through the coordinated work of the supporting mechanism, the guiding mechanism, the fixed frame and the restraining mechanism. The guiding mechanism provides reliable support and guiding functions, and the fixed frame can move smoothly along the guide rail to ensure that the prestressed steel bundle is accurately installed according to the designed position, avoiding the problem of uneven prestress transmission caused by inaccurate positioning, and improving the overall safety and service life of the structure. The fixed frame can move quickly along the guiding mechanism and cooperate with the card slot function in the restraining mechanism to quickly and accurately accommodate and fix the prestressed steel bundle, realizing the overall rapid positioning of the prestressed steel bundle. The combined design of the main reinforcement and the guide rail makes the entire positioning process smoother and more controllable. The detachable design of the guide rail enables the device to be adjusted and disassembled according to the needs of the construction site. It has strong environmental adaptability and can quickly locate the prestressed steel strands, reducing a large amount of manual measurement and positioning calibration work, thereby reducing labor costs and construction time. The prestressed steel strands can be accurately positioned and fixed according to the design requirements, so that the applied circumferential prestress is evenly distributed in the structure, solving the problem of inaccurate prestressing position in the prior art, which not only affects the effective transmission of prestressing, but may also lead to uneven stress distribution of components, reducing the safety and service life of the structure.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, a device for rapidly positioning a circumferential prestressed cable tower includes a support mechanism 1, multiple guide mechanisms 2, a fixed bent frame 3, and a restraining mechanism 4. The guide mechanisms 2 are mounted on the support mechanism 1, and the fixed bent frames 3 are mounted on the guide mechanisms 2 and are movable along the guide mechanisms 2. The guide mechanisms 2 are used to support and guide the fixed bent frames 3. The restraining mechanism 4 is mounted on the fixed bent frames 3 to accommodate and secure the prestressed steel strands.

[0021] The device provides basic support through a support mechanism 1, and a guide mechanism 2 is arranged on the support mechanism 1 and connected thereto. The existence of the guide mechanism 2 enables the fixed frame 3 to move along a predetermined path, thereby guiding and supporting the fixed frame 3. A constraint mechanism 4 is installed on the fixed frame 3. The function of the constraint mechanism 4 is to accommodate and fix the prestressed steel bundles. Through this design, the precise positioning of the prestressed steel bundles can be effectively achieved. The design of the overall device enables the prestressed steel bundles to be quickly and accurately positioned and fixed in the circumferential direction of the cable tower, thereby improving construction efficiency and positioning accuracy. The device improves construction efficiency, improves the accuracy of positioning the prestressed steel bundles, and reduces construction time. By setting the fixed frame 3 as a movable structure, it is more flexible and convenient to adjust the position of the prestressed steel bundles. The design of the constraint mechanism 4 can firmly fix the steel bundles to avoid offset problems during construction, thereby ensuring the quality and stability of construction.

[0022] In other embodiments, the support mechanism 1 can be replaced with support components of different materials or structures, such as steel mesh, frame structure, etc., to meet different construction requirements. At the same time, the form of the guide mechanism 2 can be transformed into different types of guide rails or slide rails, and the setting mode of the guide rail 21 can also be adjusted to be detachable or fixedly connected to meet the needs of different occasions. The slot 41 in the constraint mechanism 4 can be designed as a slot of different shapes or sizes, or other forms of fixing devices can be used, such as clamping devices, adjustable buckles, etc., to adapt to prestressed steel bundles of different diameters or types.

[0023] The supporting mechanism 1 includes main reinforcement 11. The main reinforcement 11 is the core component supporting the entire device and is combined with other structural components by welding or other connection methods. As an important component of the supporting mechanism 1, the main reinforcement 11 provides a solid support foundation for the entire device. The material selection and arrangement of the main reinforcement 11 directly affect the overall stability and load-bearing capacity of the device. Through reasonable structural design and material selection, the main reinforcement 11 can withstand the weight of the guide mechanism 2, the fixed frame 3 and the load above it, and ensure that the entire positioning device has sufficient strength and stability during the construction process. Using the main reinforcement 11 as a supporting component can significantly improve the load-bearing capacity and stability of the device, and ensure that no displacement or deformation occurs during the positioning of the prestressed steel bundle. At the same time, the main reinforcement 11 can be selected in terms of material and size according to specific needs, and has high design flexibility.

[0024] The main reinforcement 11 of the support mechanism 1 can be made of steel bars of different specifications and materials according to different application scenarios, or components of other shapes, such as square tubes or H-shaped steel, can be used to optimize the support structure. The connection method of the main reinforcement 11 can be changed from welding to bolt connection or other detachable connection methods to facilitate disassembly and transportation of the device.

[0025] The guide mechanism 2 includes a guide rail 21, which is detachably arranged on the top of the main reinforcement 11. The guide rail 21 is a key component of the guide mechanism 2. It is fixed to the main reinforcement 11 by a detachable connection, so that the guide rail 21 can be flexibly installed or disassembled, which is convenient for rapid assembly and maintenance of the device. The guide rail 21 provides a sliding path for the fixed rack 3, thereby realizing precise positioning and movement operation of the fixed rack 3. The detachable design of the guide rail 21 makes the device highly operable and easy to maintain, and can realize rapid disassembly and installation, greatly shortening the construction preparation time, while ensuring that the guide mechanism 2 has sufficient stability and precision during the construction process.

[0026] The guide rail 21 can be replaced with other forms of rails, such as V-shaped rails, rolling guides, etc., to meet the needs of different occasions. Different installation methods can also be selected, such as directly welding to the main reinforcement 11 or fixing it with a clamp to enhance the rigidity and durability of the structure.

[0027] The fixed frame 3 is slidably connected to the top of the guide rail 21. The fixed frame 3 cooperates with the guide rail 21 through a sliding connection, so that it can move freely along the guide rail 21. Through this sliding connection, the movement of the fixed frame 3 can be precisely controlled, thereby achieving precise positioning of the prestressed steel bundle. The sliding connection method usually adopts components such as rolling bearings or sliders to reduce friction during movement and improve positioning accuracy. The sliding connection design improves the mobility and positioning accuracy of the fixed frame 3, making the positioning operation of the prestressed steel bundle more flexible. The sliding connection structure is simple and easy to maintain, and can effectively reduce the friction resistance generated during movement, thereby improving operational efficiency.

[0028] The connection mode between the fixed rack 3 and the guide rail 21 can be transformed into other sliding connection forms such as roller sliding, chain drive, etc. to meet different operating requirements. The sliding parts can be made of different materials, such as nylon, steel sliders, etc., to adapt to different environments and load conditions.

[0029] The restraint mechanism 4 includes a plurality of slots 41, which are fixedly connected to the top of the fixed frame 3. The slots 41 are used to accommodate and fix the prestressed steel bundles. By being fixedly connected to the top of the fixed frame 3, the steel bundles can be stable and not shifted during the positioning process. The design of the slots 41 can be adjusted according to the shape and size of the steel bundle to ensure that it can firmly clamp the steel bundle. Through the arrangement of multiple slots 41, multiple steel bundles can be accommodated at the same time, thereby improving construction efficiency. Using the slots 41 as a fixing device can significantly improve the stability and accuracy of the positioning of the prestressed steel bundles. The number and layout of the slots 41 can be flexibly adjusted to meet different construction needs. The design of the slots 41 is simple and easy to operate, and can quickly fix and release the steel bundles, thereby improving construction efficiency.

[0030] The form of the slot 41 can be replaced by other fixing forms such as a clamping device or an adjustable fixture to adapt to steel bundles of different types and sizes. The material of the slot 41 can be selected from wear-resistant engineering plastics or metal materials to improve durability. The fixing method of the slot 41 can also be changed to bolt fixing or snap-on connection to facilitate installation and maintenance.

[0031] The slots 41 are evenly spaced on the top of the fixed frame 3. The evenly spaced slots 41 can ensure that the prestressed steel bundles maintain uniform spacing during arrangement, thereby achieving overall uniform force. The evenly spaced design helps construction personnel to align and adjust the position of the steel bundles more conveniently and intuitively during positioning, thereby improving construction efficiency. The evenly spaced slots 41 can significantly improve the neatness of positioning and the uniformity of force on the steel bundles, avoiding stress concentration problems caused by uneven arrangement. This design simplifies construction operations and makes the positioning process more efficient and accurate.

[0032] The distribution of the slots 41 can be adjusted to a non-uniformly spaced arrangement customized according to construction requirements to adapt to specific stress or construction needs. The spacing of the slots 41 can be flexibly adjusted according to the steel bundle specifications and layout requirements. At the same time, it can be designed into an adjustable slot 41 structure to further enhance adaptability.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
