Description

Technical Field

[0001] This utility model relates to the field of finished steel strand bundle technology, and in particular to a steel strand bundle conveying device and a steel strand bundle conveying engineering vehicle. Background Technology

[0002] As a core power transmission device in modern prestressed engineering, the technological development of steel strand conveying devices is closely linked to the evolving trends of increasingly complex building structural designs and more precise construction processes. This device uses a mechanized transmission system to directionally transport coiled steel strands to the anchorage position. Its operational efficiency directly determines the construction quality and efficiency of projects such as cable strand placement for long-span bridges, prestressed system construction for high-rise buildings, and tensioning of irregularly shaped spatial structures.

[0003] As architectural forms break through traditional geometric paradigms, engineering practices have seen a significant increase in nonlinear cableway layouts and multi-dimensional spatial curve transport. However, existing finished steel strand bundle transport devices mostly employ fixed connections or simple transformation structures, failing to adjust the orientation of the transport channel in terms of spatial orientation. This necessitates repeated relocation of the entire equipment during construction to adapt to different output requirements. For example, patent application CN105016134A discloses a dual-power pusher for transporting finished steel strand bundles with a clamping device. This device uses tracked claws to clamp and move the finished steel strand bundle by wrapping and squeezing it from both sides. However, this device is fixed to a base, making movement and adjustment inconvenient. Especially in situations requiring continuous directional changes, such as tunnel curve jacking and prestressed layout of irregularly shaped buildings, multiple and repeated disassembly / relocation / adjustment of the equipment are necessary to adapt to specific construction characteristics.

[0004] Utility model patent CN 221343320 U discloses a steel strand production traction device. This device clamps and transports steel strand bundles between multiple sets of limiting rollers. Although this patent achieves steel strand clamping through multiple sets of spring limiting rollers, the independent pressure of each set of springs leads to uneven distribution of the clamping force, which easily causes local stress concentration in the steel strand and poor clamping stability. Furthermore, the lack of a linkage pressure adjustment mechanism makes it impossible to dynamically adapt to wire diameter fluctuations, affecting clamping and conveying accuracy. In addition, the overall flexibility of the device is insufficient, and the device is inconvenient to transport, use, and adjust.

[0005] Traditional steel strand bundle conveying devices suffer from systemic limitations in spatial adaptability, dynamic adjustment capabilities, and material protection performance. These limitations frequently lead to problems in industry practice, such as mismatch between the conveying trajectory and the spatial geometry of the construction surface, damage to the protective layer of the steel strands by the clamping mechanism, and fluctuations in clamping force during variable-speed propulsion. Therefore, improving steel strand bundle conveying devices to achieve non-damaging wrapping and clamping, rapid specification adaptation, and expanded output methods to meet the diverse spatial needs of steel strand bundles, thereby enhancing the conveying accuracy and construction efficiency of finished steel strand bundles and meeting the demands of modern engineering, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] This utility model provides a steel strand bundle conveying device and a steel strand bundle conveying engineering vehicle. It utilizes a multi-dimensional and changeable output mode to efficiently meet the changing usage scenarios of steel strand bundles. It adopts an adjustable clamping unit to reconstruct the clamping module to achieve non-damaging clamping, wrapping and conveying propulsion. It effectively solves the defects of traditional output devices such as insufficient flexibility, single conveying mode, insufficient spatial adaptability, as well as damage to steel strand bundles and difficulty in adjustment.

[0007] In a first aspect, this utility model provides a steel strand bundle conveying device, including a support unit, a conveying component and a drive unit;

[0008] The support unit includes a support frame, a mobile platform, and a base;

[0009] The mobile platform is movably mounted on the support frame, and the base is mounted on the mobile platform;

[0010] The conveying assembly is mounted on the base. The conveying assembly includes two clamping units that are arranged opposite each other and have an adjustable spacing. The clamping units form a conveying channel for the steel strand bundle. Each clamping unit includes multiple clamping modules. The clamping modules of the two clamping units clamp the outer edge of the steel strand bundle at the input end of the conveying channel to convey the steel strand bundle along the conveying channel, and release the steel strand bundle at the output end of the conveying channel.

[0011] The drive unit includes a support drive component that connects to the support unit and a conveying drive component that connects to the conveying component. The support drive component drives the mobile platform to move on the support frame.

[0012] Existing steel strand bundle conveying devices mostly employ fixed support structures or single-dimensional sliding tracks, resulting in reliance on manual handling for overall device position adjustment, frequent disassembly and assembly, and wasted labor and time. The steel strand bundle conveying device provided by this invention utilizes the relative movement of a moving platform and a support frame. Driven by a support drive component, the moving platform precisely translates horizontally within the support frame, achieving rapid alignment of the conveying channel axis with the steel strand channels without manual intervention, and facilitating efficient operation of multiple steel strand channels.

[0013] Furthermore, a linear guide rail is provided on the support frame, and a slider matching the linear guide rail is provided at the bottom of the moving platform.

[0014] Furthermore, the support drive component includes a height adjustment device connected to the support frame, driving the support frame to move up and down; and / or

[0015] The support drive assembly includes an angle adjustment device that connects the base and the moving platform, which adjusts the output angle of the steel strand bundle by changing the angle between the base and the moving platform.

[0016] The configuration of linear guides, height adjustment devices, and angle adjustment devices provides a flexible, multi-dimensional spatial adaptation method for the conveying components, and can meet the needs of more working conditions with simple internal adjustments.

[0017] Preferably, the height adjustment device employs a drive device connected to the support frame to achieve the lifting and lowering movement of the support frame. The drive device includes, but is not limited to, hydraulic drive devices, motor drive devices, cylinder drive devices, screw drive devices, etc. Specifically, a scissor arm assembly / hydraulic rod can be linked with a hydraulic drive system. One end of the scissor arm / hydraulic rod is connected to the support frame via a universal hinge, and the other end is connected to a fixed base or moving unit to achieve the vertical lifting and lowering movement of the support frame. The angle adjustment device is integrated between the base and the moving platform and can also be accomplished by various drive devices, such as a sector-shaped gear disk-worm gear transmission mechanism driven by a servo motor. The worm gear meshes with the sector-shaped gear disk fixed to the base, and the tilt angle of the base is adjusted through closed-loop feedback control. A pneumatic pin-type redundant locking device is set around the periphery of the gear disk to enhance the stability of angle maintenance. The height and angle adjustment signals can be processed synchronously and coordinated by the same control terminal. Through modular transmission and redundant locking, independent or linked precise adjustment of height and angle can be achieved, better adapting to the steel strand bundle conveying requirements, and triggering the adaptive disconnection mechanism of the mechanical coupling during sudden load changes to avoid overload damage.

[0018] Furthermore, the two clamping units are respectively mounted on the base via mounting plates, and at least one of the mounting plates is movable relative to the base;

[0019] The support drive assembly also includes a spacing adjustment device connected to the mounting plate to move the mounting plate relative to the base and adjust the spacing between the two clamping units.

[0020] More preferably, the mounting plates corresponding to the two clamping units can move relative to the base. The spacing adjustment device drives the mounting plates separately to adjust the spacing between the two clamping units. The spacing adjustment device can use existing drive equipment to drive each mounting plate independently, or it can use a synchronous drive equipment, such as a linkage structure of a bidirectional lead screw and a guide slider. The bidirectional lead screw passes through the mounting plate and is threaded to each other. The two sides of the bidirectional lead screw have opposite threads. The servo motor drives the bidirectional lead screw to rotate. The difference in the thread direction causes the mounting plates on both sides to move synchronously closer or further away from the base, thereby symmetrically adjusting the spacing between the clamping units. Preferably, two bidirectional lead screws are arranged in parallel to provide sufficient driving force to the mounting plates. The bottom of the mounting plate is equipped with a guide slider that slides with the base guide rail to ensure the straightness and smoothness of the movement path. The bidirectional lead screw is equipped with a locking component, such as a spring-loaded wedge locking block at the end of the lead screw. When the spacing is adjusted to the correct position, the wedge block is pressed against the threaded surface of the lead screw by rotating the locking bolt to achieve self-locking fixation. Through the coordinated forward and reverse drive of the bidirectional lead screw and the guidance of the guide rail, the stepless adjustment of the clamping unit spacing and the maintenance of rigidity are achieved, which is conducive to adapting to steel strand bundles of different outer diameters and smoothly conveying the steel strand bundles in a compressed and damage-free manner.

[0021] Furthermore, the clamping unit is a tracked modular conveyor, with each clamping module fixed side by side on the track surface and moving along the conveying channel from the input end to the output end with the track.

[0022] Furthermore, the mounting plate is provided with a drive shaft and a driven shaft with adjustable spacing, and the track is wound around the drive shaft and the driven shaft.

[0023] The tracked modular conveyor uses a ring-shaped track that rotates and is tensioned between the drive and driven shafts, driving multiple clamping modules fixed side-by-side on the track surface to form a continuous closed-loop circulation path. When the drive wheel fixed on the drive shaft drives the track, the clamping modules move continuously from the input end to the output end along the conveying channel, using their clamping surfaces to achieve multi-point wrapping relay pushing of the steel strand bundle.

[0024] Furthermore, the tracked modular conveyor also includes a clamping force adjustment device, which includes a plurality of extrusion rollers disposed between the drive shaft and the driven shaft. The extrusion rollers press against the inner side of the track to adjust the clamping force applied by the clamping module to the outer edge of the steel strand bundle.

[0025] When the track experiences radial pressure due to clamping the steel strand bundle, the middle section of the track tends to deform inward, leading to uneven tension distribution on the sides. The clamping force adjustment device applies top pressure to the inner part of the closed-loop track, which acts on the track to counteract the inward deformation, forcibly maintaining the straightness of the central axis of the track tension section and dynamically adjusting the track tension. This, in turn, adjusts the clamping force applied to the outer edge of the steel strand bundle by the clamping modules at certain locations. For example, a set of extrusion rollers can be installed in the middle of the conveying channel to ensure sufficient clamping force at key clamping positions, guaranteeing smooth conveying of the steel strand bundle, without needing to increase the overall track tension. Compared to traditional clamping rollers that use point or line compression, leading to localized pressure surges and damage to the steel strand bundle, this clamping force adjustment device distributes the force evenly through the conveyor belt and clamping modules, preventing damage to the steel strand bundle surface caused by concentrated clamping force. Simultaneously, the tightly arranged clamping modules on the conveyor belt, combined with the groove design on their surfaces, form a continuous, enveloping clamping system, effectively limiting radial offset or torsional misalignment of the steel strand during transport. Compared to traditional discrete clamping mechanisms, this design achieves stable propulsion of the steel strand bundle with high continuity and low gap characteristics, making it particularly suitable for the stringent requirements of consistent transport trajectory in long-distance, variable-curvature tunnel construction.

[0026] Furthermore, independently liftable input guide rollers are installed on the side of the base near the input end of the conveyor channel; and / or

[0027] An independently adjustable output guide roller is installed on the side of the base near the output end of the conveyor channel.

[0028] By installing rollers at one or both ends of the base, the position and angle of the input conveying assembly and / or the steel strand bundle output from the conveying assembly can be corrected and adjusted, enabling smoother and more accurate conveying of the steel strand bundle. Preferably, the roller gap axis of the input guide roller and the output guide roller corresponds to the groove axis of each clamping module, thereby making the steel strand bundle more accurately fit with the groove of the clamping module, and ensuring stable and damage-free clamping and conveying.

[0029] Furthermore, the steel strand harness conveying device also includes a moving unit located at the bottom of the support frame. By mounting the support frame on the moving unit and adjusting its displacement and positioning, the overall working position of the conveying device can be easily adjusted. Various options are available for the moving unit, such as a moving plate with casters or other automated walking mechanisms.

[0030] Secondly, this utility model also provides a steel strand bundle conveying engineering vehicle, which is equipped with the aforementioned steel strand bundle conveying device.

[0031] This utility model has at least the following beneficial effects:

[0032] (1) This utility model significantly improves the mobility and spatial adaptability of the steel strand bundle conveying device through multi-dimensional coordinated adjustment of the support unit and the drive unit: the linear guide rail-slider structure of the support frame and the moving platform enables the moving platform to move precisely in the horizontal direction of the support frame. With the linkage of the height adjustment device and the angle adjustment device, the height, horizontal position and conveying tilt angle of the conveying channel can be adjusted as needed during construction. In addition, the steel strand bundle conveying device can be equipped with a moving unit or mounted on an engineering vehicle to cope with short-distance or long-distance changes in working position without relying on manual disassembly / manufacturing of the conveying equipment. It is especially suitable for the variable needs of the conveying trajectory in complex construction scenarios such as bridges and tunnels.

[0033] (2) This utility model is based on the continuous and stable conveying mode of the tracked modular conveyor, and utilizes the coordinated design of the clamping unit and the clamping force adjustment device to ensure the stability and low damage of the steel strand bundle conveying process.

[0039] To better understand the above technical solutions, a detailed description of the solutions will be provided below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0040] The terminology used in the embodiments of this utility model is for the purpose of describing particular embodiments only and is not intended to limit the utility model. The singular forms “a,” “the,” and “the” used in the embodiments of this utility model and the appended claims are also intended to include the plural forms, and “multiple” generally includes at least two unless the context clearly indicates otherwise.

[0041] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an article or device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or device. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the article or device that includes said element.

[0042] like Figure 1-2 As shown, this utility model provides a steel strand bundle conveying device, specifically including:

[0043] (1) A support unit, comprising a support frame 11, a mobile platform 12, and a base 13, wherein:

[0044] The support frame 11 is a rigid frame structure with linear guide rails, which is used to support the mobile platform 12 on it and provide horizontal movement guidance.

[0045] The bottom of the mobile platform 12 is integrated with a slider, which forms a sliding fit guide structure with the linear guide rail on the support frame 11;

[0046] The base 13 is a load-bearing component supported on the mobile platform 12 and is used to mount the conveying components;

[0047] (2) The conveying assembly includes two clamping units symmetrically arranged on the base 13, forming a conveying channel for the steel strand bundle between the two clamping units. Each clamping unit has an adjustable-spacing drive shaft 21 and driven shaft 22 on its mounting plate. The drive shaft 21 and driven shaft 22 are connected to the conveying motor through a coupling. A drive wheel is fixed on the drive shaft 21, and a driven wheel is fixed on the driven shaft 22. The track 23 is wound around the drive wheel and the driven wheel. The drive wheel drives the track 23 to rotate, realizing the cyclic operation of the track 23.

[0048] Multiple clamping modules 24 are fixed on the surface of the track 23. The clamping modules 24 of the clamping units on both sides are symmetrically arranged facing each other. Each clamping module 24 has a surface groove. The symmetrical clamping modules 24 cooperate to form a clamping surface that wraps around the outer edge of the steel strand bundle. Each clamping module 24 rotates continuously as the track 23 runs. The opposite clamping module 24 clamps the outer edge of the steel strand bundle at the input end of the conveying channel to convey the steel strand bundle along the conveying channel, and releases the steel strand bundle at the output end of the conveying channel, so as to realize the continuous clamping and axial propulsion of the steel strand bundle in the conveying channel.

[0049] Two clamping units are movably mounted on the base 13 via mounting plates. A spacing adjustment device 26 is connected to the mounting plates to move the mounting plates relative to the base 13, thereby adjusting the spacing between the two clamping units. Specifically, the spacing adjustment device 26 employs a linkage structure of a bidirectional lead screw and a guide slider: two parallel bidirectional lead screws are respectively threaded through the two mounting plates, with the lead screws and mounting plates threaded together. Each bidirectional lead screw has oppositely oriented threads on both sides. A servo motor drives the bidirectional lead screws to rotate, and the difference in thread direction causes the mounting plates on both sides to move synchronously closer or further away from the base 13, thus symmetrically adjusting the spacing between the clamping units. Optionally, a spring-loaded wedge-shaped locking block is provided at the end of the lead screw, which achieves self-locking by pressing the threaded surface with bolts, ensuring that the spacing rigidly remains after adjustment.

[0050] The clamping unit is also equipped with a clamping force adjustment device 25, which includes multiple extrusion rollers disposed between the drive shaft 21 and the driven shaft 22. The outer circumference of each extrusion roller contacts the inner side of the track 23 and presses inward against the inner side of the track to adjust the clamping force applied by the clamping module 24 to the outer edge of the steel strand bundle. The rigid support of the extrusion rollers in the middle span area of ​​the track 23 counteracts the inward deformation of the track 23 caused by clamping the steel strand bundle, thereby maintaining the uniform tension distribution of the track 23 and the high clamping effect of the clamping module 24 on the steel strand bundle, avoiding local loosening or stress concentration, and maintaining non-destructive clamping and stable conveying of the steel strand bundle.

[0051] An independently lifting output guide roller 27 is provided on the side of the base near the output end of the conveyor channel. Alternatively, an independently lifting input guide roller can also be provided on the side of the base 13 near the input end of the conveyor channel, with the same structure as the output guide roller 27, which is not shown.

[0052] (3) The drive unit includes a support drive assembly that connects to the support unit and a conveying drive assembly that connects to the conveying assembly.

[0053] (3.1) A support drive assembly for driving the mobile platform 12 to move on the support frame 11, and also includes a height adjustment device 31 and an angle adjustment device 32, wherein:

[0054] The height adjustment device 31 adopts a hydraulic lifting mechanism. The hydraulic rod is connected to the support frame 11. The hydraulic drive device pushes the hydraulic rod to extend and retract, so as to realize the vertical lifting of the support frame 11.

[0055] An angle adjustment device 32 is integrated between the base 13 and the moving platform 12. The rear side wall of the base 13 near the input end of the conveying channel is rotatably connected to the moving platform via a slewing bearing. The angle adjustment device 32 drives the base 13 to rotate around the slewing bearing, changing the height of the front side wall of the base 13 near the output end, thereby changing the angle between the base 13 and the moving platform 12 to adjust the output angle of the steel strand bundle. Specifically, the angle adjustment device 32 includes a servo motor-driven sector gear disk-worm gear transmission mechanism. The worm gear meshes with the sector gear disk at the bottom of the base 13, and the rotation of the worm gear drives the base 13 to rotate around the slewing bearing.

[0056] The support drive assembly also includes a hydraulic drive device for lifting and lowering the output guide roller 27 and the input guide roller, so that the roller gap axis of the input guide roller and the output guide roller 27 corresponds to the axis of the groove of each clamping module 27, thereby making the steel strand bundle more accurately match the groove of the clamping module 27 and stably and without damage clamping and conveying.

[0057] (3.2) The conveying drive unit, which drives the clamping unit of the conveying assembly and its spacing adjustment device 26 and clamping force adjustment device 25 to clamp and convey the steel strand bundle. In addition, when the input guide rollers and output guide rollers 27 need to apply clamping traction to the steel strand bundle or adjust the conveying tension of the steel strand bundle, the conveying drive unit can also be equipped with a motor drive device that can drive the input guide rollers and output guide rollers 27 to rotate and pull.

[0058] (4) Optionally, a moving unit is added to the bottom of the support frame 11. The moving unit can drive the support frame 11 and its conveying components and drive units to move flexibly in the horizontal plane and lock in position, thereby improving the convenience of the conveying device for short-distance movement and use.

[0059] like Figure 3 As shown, this utility model also provides a steel strand bundle conveying engineering vehicle equipped with the above-mentioned steel strand bundle conveying device, thereby further improving the engineering application range and flexible mobility of the steel strand bundle conveying device. When mounted on the engineering vehicle, the aforementioned moving unit for small-range adjustments is no longer required.

[0060] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if such modifications and modifications fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and modifications.
