Description

Technical Field

[0001] This utility model relates to the field of rigid contact wire technology for subways, specifically a rapid repair device for a rigid contact wire suspension system in subways. Background Technology

[0002] A rigid overhead contact system for subways is a type of contact network used in subway power supply systems. It consists of a contact wire, busbars, support devices, and positioning devices. The contact wire is the part that directly contacts the pantograph to supply power to the train; the busbars are used to fix the contact wire and collect and conduct current; the support devices and positioning devices fix the contact network to the tunnel or elevated structure and ensure that the position and height of the contact wire meet the requirements for train operation.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN216101658U) discloses a rapid repair device for rigid contact wire suspension in urban rail transit, comprising a support device and a positioning device. The support device includes a suspension base and fixing bolts, which secure the suspension base within a shield section located at the top of a subway tunnel. The positioning device includes a busbar positioning clamp, a pin insulator, a B-type channel steel base, and T-bolts, and is used to bear the vertical and horizontal loads at the suspension point. This rapid repair device for rigid contact wire suspension in urban rail transit has a simple structure, strong adaptability, and enables rapid disassembly, assembly, and repair of the contact wire.

[0004] While the aforementioned patent improves the maintenance efficiency of rigid contact networks through the design of positioning devices, support devices, and other components, and enhances maintenance stability by quickly and stably connecting the suspension base to the shield section using fixing bolts, the complex emergency repair environment of subways and the varying emergency repair situations necessitate operators standing on platforms at a certain height. Different repair tools are often required depending on the situation, and repeatedly passing tools wastes repair time. If all tools are stored in a storage box, searching for them is necessary, making it inconvenient for maintenance personnel to quickly retrieve the appropriate tools and reducing repair efficiency.

[0005] Therefore, this utility model provides a rapid repair device for a rigid contact wire suspension system in subways to solve the above-mentioned problems. Utility Model Content

[0025] 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.

[0026] This utility model provides a rapid repair device for a rigid contact wire suspension system in a subway, such as... Figures 1-4 As shown, the subway rigid contact wire suspension rapid repair device includes a box 1, a partition plate 2 is fixedly connected inside the box 1, and a lifting component is installed inside the box 1.

[0027] The lifting assembly includes a lifting plate 3 that is slidably connected to the side wall of the partition plate 2. A drive box 4 is provided on the side wall of the housing 1. An air pump 5 is installed at the bottom inner end of the drive box 4. An air inlet pipe 6 is fixedly connected to the bottom of the housing 1 at the lifting plate 3. The end of the air inlet pipe 6 is fixedly connected to the output end of the air pump 5. A valve 7 is rotatably connected to the outer wall of the air inlet pipe 6. A valve core 8 is fixedly connected to the end of the valve 7. An adjustment assembly is provided at the top of the partition plate 2.

[0028] The adjustment assembly includes an adjustment plate 9 that is slidably connected to the top of the partition plate 2, and a compression spring 10 is fixedly connected inside the adjustment plate 9.

[0029] The adjustment assembly also includes a slot 11 formed on the inner wall of the housing 1, and the end of the compression spring 10 is engaged with the slot 11 by a ball 12.

[0030] A filter box 13 is fixedly connected to the side wall of the drive box 4, and a filter plate 14 is snapped into the inner wall of the filter box 13. A door is rotatably connected to the outer wall of the drive box 4 via a hinge.

[0031] Specifically, the partition 2 allows for the categorization of various tools, preventing clutter and ensuring quick access for maintenance personnel, thus reducing maintenance efficiency. The lifting assembly, through the coordinated operation of its components, allows tools within the housing 1 to be quickly lifted and brought to the maintenance personnel's reach. Simultaneously, the operation of valve 7 by the maintenance personnel raises the corresponding lifting plate 3, further lifting tools within that area and improving retrieval efficiency. The operation of air pump 5 rapidly delivers compressed air through the air inlet pipe 6 into the housing 1. This continuous influx of air causes the lifting plate 3 to slide along the inner wall of the partition 2, allowing tools in a designated area to be accessed. When lifted, the opening and closing of valve 7 drives valve core 8 to rotate inside air inlet pipe 6, thereby controlling the flow of gas to achieve the lifting of designated area lifting plate 3. With the setting of adjustment plate 9, the space in the lifting area can be adjusted by the sliding displacement of adjustment plate 9, so that some larger tools can be placed. With the setting of slot 11, compression spring 10 and locking ball 12, adjustment plate 9 can be stably locked inside box 1. This component has a simple structure and strong practicality. During emergency repair, it can facilitate maintenance personnel to quickly repair rigid contact wire suspension by means of abundant tools and quick access, avoiding the waste of physical strength caused by repeatedly picking up tools.

[0032] A support column 15 is fixedly connected to the bottom end of the housing 1, and a mounting plate 16 is fixedly connected to the bottom end of the support column 15. The outer wall of the mounting plate 16 has a mounting groove.

[0033] A carrying handle 17 is fixedly connected to the side wall of the box 1, and a light is fixedly connected to the outer wall of the box 1.

[0034] Specifically, the support column 15 and the mounting plate 16 facilitate the stable connection of the housing 1 to the work platform, ensuring its stability during use. The lighting can be improved during maintenance, thereby increasing maintenance efficiency.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
