Description

Technical Field

[0001] This utility model relates to the field of overhead contact line maintenance technology, and in particular to an aging detection device for railway overhead contact line insulation components. Background Technology

[0002] With the rapid development of railway electrification, the railway catenary, as an important facility for supplying power to electric locomotives, is of paramount importance for its safe operation. Insulating components, as key parts of the catenary, play a crucial role in electrical insulation. However, due to long-term exposure to the complex outdoor environment, insulating components are susceptible to contamination, aging, mechanical damage, and other factors, leading to a decline in insulation performance, power supply failures, and endangering railway traffic safety. Existing detection methods, such as manual inspection, are inefficient, subjective, and difficult to detect internal hidden dangers; traditional detection equipment also suffers from insufficient detection accuracy and the inability to monitor in real time.

[0003] In the existing technology, multiple cameras are used to photograph the overhead contact line, and the measurement position is roughly determined manually. However, different shooting angles and distances result in different images, which increases the workload of subsequent analysis. Furthermore, the spacing between different overhead contact lines is difficult to control, which also increases the workload of data processing.

[0004] To address the aforementioned issues, an existing patent (publication number: CN210070929U) proposes a railway contact network insulation component aging detection device. This device uses a camera electrically connected to a chassis via wires. A movable frame is fixedly connected to the bottom of the chassis, and a three-section telescopic cylinder is fixedly connected to the top. This invention relates to the field of measurement equipment technology. The contact network geometric parameter detection device uses a three-section telescopic cylinder to control three sets of frames and cameras, allowing for multi-angle imaging of the contact network. The three-section telescopic cylinder is retractable for easy storage. The movable frame, in conjunction with sliding wheels, allows for convenient movement of the device on the track. A positioning rope, combined with a metal hook, can hook onto the metal frame of the contact network, ensuring proper positioning and maintaining the distance between the device and the metal frame. This improves the accuracy of the imaging and measurement, reduces the difficulty of subsequent data analysis, and eliminates the need for manual measurement, significantly saving time.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the flexibility and safety of the testing equipment in the existing technologies and the examples described above are poor. They are fixed installation methods and have a single adjustment mode. Furthermore, they do not take additional protective measures. Secondly, they rely on a single protective cover for protection. When the protective cover is blocked, it still affects the quality and effectiveness of the testing operation. Moreover, the protective cover and the testing equipment are difficult to assemble and disassemble, making the preparation and subsequent processing operations time-consuming and resulting in low efficiency.

[0006] To address this issue, an aging detection device for railway contact wire insulation components is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a railway contact wire insulation component aging detection device, which can solve the problems of poor flexibility and safety caused by the installation method of existing detection equipment, as well as the low efficiency caused by the difficulty of disassembly and assembly.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an aging detection device for railway contact wire insulation components, comprising a 4C probe, wherein an adjustment and protection mechanism is movably connected to the outer side of the 4C probe, and a convenient disassembly and assembly mechanism is movably connected to the inner side of the adjustment and protection mechanism;

[0009] The adjustment and protection mechanism includes an electric telescopic cylinder, a support circular plate, a protective circular cover, and a reciprocating cleaning assembly. The 4C probe is located on the top of the support circular plate, the electric telescopic cylinder is fixedly connected to the bottom of the support circular plate, the protective circular cover is movably connected to the outside of the electric telescopic cylinder, the protective circular cover is located outside of the 4C probe, the reciprocating cleaning assembly is movably connected to the outside of the support circular plate, and the reciprocating cleaning assembly is located outside of the protective circular cover.

[0010] Preferably, the convenient assembly and disassembly mechanism includes a clamping block, a sliding block, a guide gear ring, an arc groove, and a drive gear.

[0011] Preferably, the clamping block is slidably connected to the bottom of the protective circular cover, and the sliding block is fixedly connected to the bottom of the clamping block.

[0012] Preferably, the arc-shaped groove is formed on the inner side of the guide gear ring, the sliding block is movably connected to the inner side of the arc-shaped groove, the drive gear is meshed with the outer side of the guide gear ring, and the drive gear is movably connected to the bottom of the reciprocating cleaning assembly.

[0013] Preferably, the reciprocating cleaning assembly includes a support ring, a support toothed ring, an annular sweeping rod, and a drive tooth.

[0014] Preferably, the support ring is fixedly connected to the outside of the protective cover, the drive gear is movably connected to the bottom of the support ring, the support tooth ring is movably connected to the top of the support ring, the annular sweeping rod is fixedly connected to the top of the support tooth ring and is disposed on the outside of the protective cover, the drive residual tooth is movably connected to the outside of the support tooth ring and the drive residual tooth is movably connected to the top of the support ring.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting up an adjustable protective mechanism, replaces the original support base of the 4C probe with an electric telescopic cylinder and provides protection with a self-cleaning protective cover. By setting up an electric telescopic cylinder, the 4C probe is freed from the fixed connection method and can flexibly adjust its height and angle during movement, improving detection flexibility. The protective cover enhances safety. To address the problem of the protective cover being easily blocked by debris, a ring-shaped sweeping rod with driving residual teeth is used. The driving residual teeth on both sides rotate in a staggered manner, driving the supporting toothed ring to rotate back and forth, realizing that the ring-shaped sweeping rod sweeps the outside of the protective cover, promptly removing debris. This solves the problems of poor flexibility and safety of detection equipment, imperfect protective measures, and the impact of the protective cover being blocked on detection, effectively improving the accuracy and stability of detection.

[0019] 2. This application, by setting up a convenient disassembly and assembly mechanism, enables the rapid installation of the protective cover, and the top can be opened to facilitate the installation of a larger 4C probe, making it convenient for quick replacement at the starting and ending stations. Through the cooperation of the drive gear and the guide gear ring, the inner arc groove of the drive gear squeezes the sliding block, driving the clamping block to move, thereby achieving rapid clamping of the extension part of the electric telescopic cylinder, completing the installation of the protective cover, solving the problem of disassembly and assembly of the protective cover, greatly shortening the preparation and subsequent processing time, and improving efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] An aging detection device for railway contact wire insulation components includes a 4C probe 1, an adjustment and protection mechanism 2 movably connected to the outer side of the 4C probe 1, and a convenient disassembly and assembly mechanism 3 movably connected to the inner side of the adjustment and protection mechanism 2.

[0029] The adjustment and protection mechanism 2 includes an electric telescopic cylinder 21, a support circular plate 22, a protective circular cover 23, and a reciprocating cleaning assembly 24. The 4C probe 1 is located on the top of the support circular plate 22. The electric telescopic cylinder 21 is fixedly connected to the bottom of the support circular plate 22. The protective circular cover 23 is movably connected to the outside of the electric telescopic cylinder 21 and is located outside the 4C probe 1. The reciprocating cleaning assembly 24 is movably connected to the outside of the support circular plate 22 and is located outside the protective circular cover 23.

[0030] In this embodiment, the original 4C probe 1 mounting bracket is replaced by an electric telescopic cylinder 21 and a support circular plate 22, allowing it to be raised and lowered. A protective cover 23 is installed on the outside of the support circular plate 22 to protect the 4C probe 1 and prevent debris from directly damaging it. The reciprocating cleaning component 24 can clean the protective cover 23 to prevent debris from obstructing it and affecting the 4C probe 1 detection operation. In summary, this improves the accuracy and stability of detecting aging problems of railway contact wire insulation components.

[0031] Specifically, such as Figure 1 , Figure 4 As shown, the convenient disassembly and assembly mechanism 3 includes a clamping block 31, a sliding block 32, a guide gear ring 33, an arc groove 34, and a drive gear 35.

[0032] Specifically, such as Figure 1 , Figure 4 As shown, the clamping block 31 is slidably connected to the bottom of the protective cover 23, and the sliding block 32 is fixedly connected to the bottom of the clamping block 31.

[0033] Specifically, such as Figure 1 , Figure 4As shown, the arc-shaped groove 34 is formed on the inner side of the guide gear ring 33, the sliding block 32 is movably connected to the inner side of the arc-shaped groove 34, the drive gear 35 is meshed with the outer side of the guide gear ring 33, and the drive gear 35 is movably connected to the bottom of the reciprocating cleaning assembly 24.

[0034] In this embodiment: During installation, the protective cover 23 is first vertically fitted onto the outside of the electric telescopic cylinder 21. Then, the motor at the bottom of the support ring 24a is started, driving the drive gear 35 to rotate. The guide gear ring 33, which meshes with the outer side of the drive gear 35, rotates accordingly. During rotation, the arc groove 34 on the inner side of the drive gear 35 presses the sliding block 32, causing it to move along the arc groove 34. This moves the four sets of sliding blocks 32 and the top clamping block 31. Since the clamping block 31 is slidably connected to the bottom of the protective cover 23, the four sets of clamping blocks 31 simultaneously clamp the extension part of the electric telescopic cylinder 21 inward, quickly completing the installation of the protective cover 23. This facilitates the quick replacement of the protective cover 23 or the 4C probe 1 at the starting and ending stations. The top of the protective cover 23 can be opened. If the 4C probe 1 is large, the protective cover 23 can be installed first, followed by the 4C probe 1.

[0035] Specifically, such as Figure 2 , Figure 3 As shown, the reciprocating cleaning assembly 24 includes a support ring 24a, a support toothed ring 24b, an annular sweeping bar 24c, and a drive residual tooth 24d.

[0036] Specifically, such as Figure 2 , Figure 3 As shown, the support ring 24a is fixedly connected to the outside of the protective cover 23, the drive gear 35 is movably connected to the bottom of the support ring 24a, the support tooth ring 24b is movably connected to the top of the support ring 24a, the annular sweeping rod 24c is fixedly connected to the top of the support tooth ring 24b and is located on the outside of the protective cover 23, the drive residual tooth 24d is movably connected to the outside of the support tooth ring 24b and the drive residual tooth 24d is movably connected to the top of the support ring 24a.

[0037] In this embodiment: When the 4C inspection vehicle is running, the protective cover 23 is easily obstructed by debris, affecting the detection of the 4C probe 1. To address this, a drive tooth 24d is provided on the top of the support ring 24a, and the two are assembled together on both sides of the annular sweeping rod 24c. The motor is located at the bottom of the support ring 24a. The drive tooth 24d has toothed and toothless surfaces. When the toothed surface rotates to one side of the support toothed ring 24b, it engages with the toothed surface for transmission. When the toothless surface rotates to the other side, it disengages and stops transmission. The drive tooth 24d on both sides of the annular sweeping rod 24c is misaligned, with one side having a toothed surface and the other side having a toothless surface. This drives the support toothed ring 24b to rotate back and forth, allowing the annular sweeping rod 24c to sweep the outside of the annular protective cover, remove debris, ensure the detection field of the 4C probe 1, and improve the accuracy and stability of the aging detection of railway contact wire insulation components.

[0038] Specifically, such as Figure 3As shown, the outer side of the clamping block 31 is movably connected to an elastic clamping pad 4.

[0039] Specifically, such as Figure 5 As shown, the 4C probe 1 is movably connected to the inner side of the adjustment frame 5, and the adjustment frame 5 is movably connected to the top of the support circular plate 22.

[0040] In this embodiment: the elastic clamping pad 4 is set on the outside of the clamping block 31, which increases the friction of the clamping surface of the clamping block 31 and adapts to the shape of the clamping surface. The adjustment frame 5 is set so that the probe can be adjusted up and down and left and right, and the electric telescopic cylinder 21 can be used to rotate the viewing angle more flexibly.

[0041] Working Principle: The 4C inspection vehicle plays a crucial role in detecting aging issues of railway catenary insulation components. Equipped with thirty-six sets of 4C probes 1 on its roof, this vehicle can capture comprehensive images of the entire railway catenary section, recording and detecting the aging condition of the insulation components. Traditionally, the 4C probes 1 are directly fixed to the top of the 4C inspection vehicle, resulting in a rigid inspection method. Instead of a fixed connection, an electric telescopic cylinder 21 corresponding to the number of 4C probes 1 is installed on the top of the 4C inspection vehicle. The 4C probes 1 are then mounted on an adjusting frame 5, which is then mounted on a support plate 22 on top of the electric telescopic cylinder 21. This allows the 4C probes 1 to be adjusted in height and angle during movement. To better record data, a protective dome 23 is used to protect the 4C probe 1. During installation, the protective dome 23 is first placed outside the electric telescopic cylinder 21 and kept vertical. Then, the drive gear 35 at the bottom of the support ring 24a is activated. Its motor is located at the bottom of the support ring 24a. The drive gear 35 rotates, driving the guide gear ring 33 meshing with its outer side to rotate. During the rotation, the arc groove 34 on the inner side of the drive gear 35 squeezes the sliding block 32, causing it to move along the guide direction of the arc groove 34. This, in turn, drives the four sets of sliding blocks 32 and the clamping block 31 on top to move. Since the clamping block 31 is slidably connected to the bottom of the protective dome 23, the four sets of clamping blocks 31 are ultimately clamped inward simultaneously. The extension of the electric telescopic cylinder 21 allows for quick installation of the protective cover 23, facilitating rapid replacement of the protective cover 23 or the 4C probe 1 at the starting and ending stations. Furthermore, the top of the protective cover 23 can be opened; if the 4C probe 1 is large, the protective cover 23 can be installed first, followed by the 4C probe 1. After installation, this effectively protects the 4C probe 1 from obstruction by debris or wear and corrosion due to harsh weather. When the 4C inspection vehicle is running, the protective cover 23 may be obstructed by debris, affecting the 4C probe 1's inspection operation. Therefore, drive teeth 24d are installed on the top of the support ring 24a, in pairs, mounted on both sides of the annular sweeping rod 24c. Their motors... Located at the bottom of the support ring 24a, the driving residual tooth 24d consists of a toothed surface and a toothless surface. When the toothed surface rotates to the side of the support ring 24b, it meshes with the support ring 24b and drives the transmission. When the toothless surface rotates to the support ring 24b, it disengages and stops driving the transmission. The driving residual teeth 24d on both sides of the annular sweeping rod 24c are staggered, with one side having a toothed surface and the other side having a toothless surface. In this way, the support ring 24b can be driven to rotate back and forth, thereby causing the annular sweeping rod 24c at the top of the support ring 24b to sweep and beat the outside of the annular protective cover, sweeping away and tearing away debris, preventing it from affecting the detection field of the 4C probe 1, and improving the accuracy and stability of the detection of aging problems of railway contact wire insulation components.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
