Description

Technical Field

[0001] This utility model belongs to the field of displacement gauge installation technology, specifically relating to a fixed connection structure for a pull-wire displacement gauge. Background Technology

[0002] Currently, the draw-wire displacement gauge is a commonly used displacement measurement tool. Its working principle involves pulling a flexible steel wire connected to the object being measured, converting the object's linear displacement into angular displacement as measured by an absolute encoder, thus achieving displacement measurement. However, existing traditional draw-wire displacement gauges have significant limitations when applied to monitoring deformation of large-area metal roofs:

[0003] 1. Lack of reliable fasteners, making it difficult to use in extreme weather conditions: Traditional wire-type displacement gauges often lack specialized fasteners designed for metal roofs during installation. This makes the gauge body and wire connection prone to shaking, displacement, or even damage in extreme weather conditions such as strong winds and heavy rain, severely affecting measurement accuracy and reliability, and even preventing normal operation. The overturning moment caused by severe weather conditions is also more likely to lead to measurement deviations.

[0004] 2. Limited measuring range, unable to cover large areas: Traditional wire-type displacement gauges typically have a limited measuring range. For large-area metal roofs, especially where it is necessary to monitor the deformation of multiple key parts, the measuring range of a single displacement gauge is insufficient to cover the entire area. This necessitates the deployment of numerous sensors, resulting in high costs, complex wiring, and difficult maintenance.

[0005] Furthermore, traditional wire-type displacement gauges generally lack dedicated fixing structures in practical applications, making it difficult to achieve stable and accurate measurements in complex environments. To address this issue and effectively monitor minute deformations of roof metal panels caused by factors such as thermal expansion and contraction or wind loads in the whole-roof health monitoring system of railway stations, this application proposes a dedicated fixing component that can reliably fix a wire-type displacement gauge to the surface of a metal panel. Utility Model Content

[0006] The purpose of this invention is to provide a fixed connection structure for a pull-wire displacement gauge to improve the overall wind resistance and monitoring accuracy of the system. This fixing component has a simple structure, is easy to install, and can ensure the stability and measurement accuracy of the displacement gauge during long-term operation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A fixed connection structure for a pull-wire displacement gauge includes a fixed support, an angle aluminum reinforcement and multiple wind-resistant clamps. The fixed support includes a first clamp and a second clamp, and a first fastening bolt is connected between the first clamp and the second clamp. A horizontally arranged first fixing plate is formed on the top of the first clamp, and a fixing frame is provided on the first fixing plate. The pull-wire displacement gauge is installed inside the fixing frame.

[0009] The wind-resistant clamp includes a third clamp and a fourth clamp, and a second fastening bolt is connected between the third clamp and the fourth clamp. A second fixing plate is provided on the top of the third clamp, and a vertically arranged limiting plate is provided on the top of the second fixing plate. The pull-wire displacement gauge is connected to a steel strand and passes through the limiting plates on each wind-resistant clamp in sequence and is connected to them respectively.

[0010] The cross-sectional profile of the angle aluminum reinforcement is L-shaped, and the angle aluminum reinforcement is set on the top of the fixed support or the top of the wind-resistant clamp.

[0011] The working process and principle of the above structure are as follows:

[0012] The fixed support is secured to the roof of the railway station building via a first and a second clamp. The wire-operated displacement gauge is then fixed to the fixed support via a first fixing plate and a fixing frame, ensuring the displacement gauge's stability and reliability under various working conditions and preventing shaking or displacement. This significantly improves the working stability of the wire-operated displacement gauge in severe weather conditions such as strong winds, heavy rain, and snow. The limiting plate on the second fixing plate connects the wire-operated displacement gauge body to the limiting plate via steel strands. The limiting plate ensures a stable connection between the wire-operated displacement gauge and the metal roof panel structure, firmly securing it. The structure is fixed to the limiting plate, ensuring its robustness. The wind-resistant clamp and the limiting plate allow it to be connected to the wire displacement gauge via steel strands, effectively expanding the coverage of the wire displacement gauge for monitoring the deformation of the metal roof panel. The angle aluminum reinforcement connects the wind-resistant clamp and the fixed support, firmly fixing the wire displacement gauge to the wind-resistant clamp on the metal roof panel. This reduces measurement errors caused by the displacement of the wire displacement gauge and the fixed support itself, and prevents overturning moments caused by the weight of the displacement gauge or wind pressure, thereby improving the overall measurement accuracy.

[0013] Furthermore, each of the first fixing plates has two fixing brackets. The fixing brackets are U-shaped grooves with two groove sides extending horizontally outward to form fixing edges. The two fixing brackets are arranged side by side and close to each other. Each fixing bracket is connected to the first fixing plate by bolts through the two fixing edges. A semi-circular through hole is opened in the middle of the adjacent side of the top of the two fixing brackets. The two semi-circular through holes are combined to form a circular through hole. The top of the pull-wire displacement gauge passes through the circular through hole.

[0014] The two mounting brackets can better confine the wire-type displacement gauge within the circular through hole, and the U-shaped groove structure of the mounting brackets does not affect the connection of the wire-type displacement gauge to the steel strand and the wire.

[0015] Furthermore, a first slot is provided at the center of the first fixing plate, and the two ends of the first slot are connected; a second slot is provided at the center of the second fixing plate, and the two ends of the second slot are connected; the cross-sectional contours of the first slot and the second slot are the same, both being convex-shaped structures, and the cross-sectional areas of the first slot and the second slot are the same.

[0016] The first and second slots are designed with a convex shape, which makes it easy to fit the bolts into the first and second slots, thus facilitating the fixation of the angle aluminum reinforcement.

[0017] Furthermore, when both ends of the angle aluminum reinforcement are connected to the two wind-resistant clamps, a third fastening bolt is installed in the second slot of each of the two wind-resistant clamps, and the angle aluminum reinforcement is connected to the wind-resistant clamp through the third fastening bolt; when one end of the angle aluminum reinforcement is connected to the first fixing plate and the other end is connected to the second fixing plate, one end of the angle aluminum reinforcement is fixed to the first fixing plate by a bolt connecting the fixing bracket, and a gasket is provided on the upper surface of the second fixing plate connected to the other end of the angle aluminum reinforcement. The third fastening bolt in the second slot of the second fixing plate passes through the gasket and is connected to the angle aluminum reinforcement, and the angle aluminum reinforcement is positioned above the fixing edge on the corresponding side.

[0018] The head of the third fastening bolt slides and is locked in the second slot to limit the position of the third fastening bolt, and finally fixes the angle aluminum reinforcement with a nut. Due to the setting of the fixed side of the fixing frame, a shim is set on the second fixing plate to ensure the height stability of the angle aluminum reinforcement, thereby connecting the first fixing plate and the second fixing plate together to ensure stability.

[0019] Furthermore, the first clip has a groove formed at the lower part of the first fixing plate, and the top of the second clip has a protrusion formed towards the first clip, the protrusion engaging with the groove. The lower ends of both the first and second clips have arc-shaped grooves formed, the axes of the two arc-shaped grooves coinciding. The first fastening bolt is located between the arc-shaped groove and the groove, passes through the first and second clips, and is fixed. The third and fourth clips have the same structure as the first and second clips at the lower part of the second fixing plate.

[0020] The grooves and raised strips facilitate maintaining a stable distance between the first and second clips. The first and second clips are fixed together by the first fastening bolt. The two arc-shaped grooves facilitate the fixing of the support onto the circular raised strip on the metal roof panel. The third and fourth clips have the same structure as the first and second clips, which also facilitates fixing the wind-resistant clips onto the metal roof panel.

[0021] Furthermore, the width of the first fixing plate is greater than the width of the second fixing plate.

[0022] The width of the first fixing plate is greater than that of the second fixing plate, mainly to facilitate the installation of the two fixing brackets.

[0023] Beneficial effects: This utility model, through the setting of a fixed support, wind-resistant clamp, and angle aluminum reinforcement, makes the wire displacement meter more adaptable to the environment and more reliable, and can be used stably under extreme weather conditions; by connecting the wire displacement meter on the fixed support to the wind-resistant clamp through steel strand, a larger measurement range can be obtained, which can cover a large area of ​​metal roof; by connecting the fixed support and the wind-resistant clamp through the angle aluminum reinforcement, the wire displacement meter has higher measurement accuracy.

Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0031] Example:

[0032] like Figures 1-5 As shown, this embodiment provides a fixed connection structure for a pull-wire displacement gauge, including a fixed support 1, an angle aluminum reinforcement 2 and multiple wind-resistant clamps 3. The fixed support 1 includes a first clamp 4 and a second clamp 5. A first fastening bolt 6 is connected between the first clamp 4 and the second clamp 5. A horizontally arranged first fixing plate 7 is formed on the top of the first clamp 4. A fixing frame 8 is provided on the first fixing plate 7. A pull-wire displacement gauge 9 is provided inside the fixing frame 8.

[0033] The wind-resistant clamp 3 includes a third clamp 10 and a fourth clamp 11. A second fastening bolt 12 is connected between the third clamp 10 and the fourth clamp 11. A second fixing plate 13 is provided on the top of the third clamp 10. A vertically arranged limiting plate 14 is provided on the top of the second fixing plate 13. A pull-wire displacement gauge 9 is connected to a steel strand 15 and passes through the limiting plate 14 on each wind-resistant clamp 3 in sequence and is connected to it respectively.

[0034] The angle aluminum reinforcement 2 has an L-shaped cross-sectional profile and is installed on top of the fixed support 1 or the wind-resistant clamp 3. The fixed support 1, the angle aluminum reinforcement 2, and the wind-resistant clamp 3 are all made of aluminum alloy, which has lower production costs and higher consistency.

[0035] The working process and principle of the above structure are as follows:

[0036] The fixed support 1 is fixed to the roof of the railway station building by the first clamp 4 and the second clamp 5. The wire-type displacement gauge 9 is fixed to the fixed support 1 by the first fixed plate 7 and the fixed frame 8, ensuring the displacement gauge is stable and reliable under various working conditions and preventing shaking or displacement. This significantly improves the working stability of the wire-type displacement gauge 9 under severe weather conditions such as strong winds, heavy rain, and snow. The limiting plate 14 on the second fixed plate 13 connects the wire-type displacement gauge 9 to the limiting plate 14 via the steel strand 15. The limiting plate 14 ensures a stable connection between the wire-type displacement gauge 9 and the metal roof panel structure, and... The clamp 3 is firmly fixed to the limiting plate 14, ensuring the structural integrity. The setting of the limiting plate 14 through the wind-resistant clamp 3 allows it to be connected to the wire displacement gauge 9 via the steel strand 15, effectively expanding the coverage of the wire displacement gauge 9 for monitoring the deformation of the metal roof panel. The angle aluminum reinforcement 2 connects the wind-resistant clamp 3 and the fixed support 1, firmly fixing the wire displacement gauge 9 to the wind-resistant clamp 3 on the metal roof panel, reducing the measurement error caused by the displacement of the wire displacement gauge 9 and the fixed support 1 themselves, and preventing the overturning moment caused by the weight of the displacement gauge or wind pressure, thereby improving the overall measurement accuracy.

[0037] In another embodiment of this utility model, such as Figures 1-5 As shown, each first fixing plate 7 has two fixing brackets 8. The fixing brackets 8 have a U-shaped groove structure and two groove sides extend horizontally outward to form fixing edges. A round hole is opened on each fixing edge. The first fixing plate 7 has four round holes. The two fixing brackets 8 are arranged side by side and close to each other. Each fixing bracket 8 is connected to the first fixing plate 7 by bolts through two fixing edges. A semi-circular through hole is opened in the middle of the side of the two fixing brackets 8 that are close to each other at the top. The two semi-circular through holes are combined to form a circular through hole. The top of the pull-wire displacement gauge 9 passes through the circular through hole.

[0038] The two mounting brackets 8 can better confine the wire-type displacement gauge 9 within the circular through hole, and the U-shaped groove structure of the mounting bracket 8 does not affect the connection of the wire-type displacement gauge 9 to the steel strand 15 and the wire.

[0039] In another embodiment of this utility model, such as Figures 1-5 As shown, a first slot 16 is provided in the center of the first fixing plate 7, and four round holes on the first fixing plate 7 are symmetrically distributed on both sides of the first slot 16. Two round holes on the same side correspond to two round holes on the same fixing bracket 8. The two ends of the first slot 16 are connected. A second slot 17 is provided in the center of the second fixing plate 13. The two ends of the second slot 17 are connected. The cross-sectional contours of the first slot 16 and the second slot 17 are the same, both being convex-shaped structures, and the cross-sectional areas of the first slot 16 and the second slot 17 are the same.

[0040] The first slot 16 and the second slot 17 are designed with a convex shape, which makes it easy to fit the bolt into the first slot 16 and the second slot 17, thereby facilitating the fixation of the angle aluminum reinforcement 2.

[0041] In another embodiment of this utility model, such as Figures 1-5 As shown, when the two ends of the angle aluminum reinforcement 2 are connected to the two wind-resistant clips 3, the second slots 17 of the two wind-resistant clips 3 are each equipped with a third fastening bolt 18, and the angle aluminum reinforcement 2 is connected to the wind-resistant clips 3 through the third fastening bolt 18; when one end of the angle aluminum reinforcement 2 is connected to the first fixing plate 7 and the other end is connected to the second fixing plate 13, one end of the angle aluminum reinforcement 2 is fixed to the first fixing plate 7 by the bolts of the connecting fixing bracket 8, and a gasket is provided on the upper surface of the second fixing plate 13 connected to the other end of the angle aluminum reinforcement 2. The third fastening bolt 18 in the second slot 17 on the second fixing plate 13 passes through the gasket and is connected to the angle aluminum reinforcement 2. The angle aluminum reinforcement 2 is located above the fixing edge on the corresponding side.

[0042] The head of the third fastening bolt 18 is slidably locked in the second slot 17 to limit the position of the third fastening bolt 18, and finally the angle aluminum reinforcement 2 is fixed by the nut. Due to the setting of the fixed side of the fixing bracket 8, a shim is set on the second fixing plate 13 to ensure the height stability of the angle aluminum reinforcement 2, thereby connecting the first fixing plate 7 and the second fixing plate 13 together to ensure stability.

[0043] In another embodiment of this utility model, such as Figures 1-5 As shown, the first clip 4 has a groove formed at the lower part of the first fixing plate 7, and the top of the second clip 5 has a protrusion formed towards the first clip 4. The protrusion engages with the groove. The lower ends of the first clip 4 and the second clip 5 are both formed with arc-shaped grooves 19, and the axes of the two arc-shaped grooves 19 coincide. The first fastening bolt 6 is located between the arc-shaped groove 19 and the groove, passes through the first clip 4 and the second clip 5, and is fixed. The third clip 10 and the fourth clip 11 are located at the lower part of the second fixing plate 13 and have the same structure as the first clip 4 and the second clip 5, respectively.

[0044] The grooves and raised strips facilitate maintaining a stable distance between the first clip 4 and the second clip 5. The first clip 4 and the second clip 5 are fixed together by the first fastening bolt 6. The two arc-shaped grooves 19 facilitate the fixing of the support 1 onto the circular raised strip on the metal roof panel. The third clip 10 and the fourth clip 11 have the same structure as the first clip 4 and the second clip 5, which also facilitates fixing the wind-resistant clip 3 onto the metal roof panel.

[0045] In another embodiment of this utility model, such as Figures 1-5 As shown, the width of the first fixing plate 7 is greater than the width of the second fixing plate 13.

[0046] The width of the first fixing plate 7 is greater than that of the second fixing plate 13, which is mainly to facilitate the installation of the two fixing brackets 8.
