Description

Technical Field

[0001] This application belongs to the field of platform vehicle technology, and in particular relates to a double-layer platform vehicle for overhead contact lines and its usage method. Background Technology

[0002] In the inspection and maintenance of the overhead contact system of electrified railways, the pantograph, as a key component connecting the work vehicle and the contact system, directly affects the accuracy of the inspection data and the personal safety of the workers. In actual operation, the pantograph is not always in a raised, current-collecting state. When the work vehicle is parked in different sections or when non-contact observation is being conducted, the pantograph must be lowered and kept in a low, non-operating position.

[0003] However, in actual use, existing double-decker platform trucks pose a risk that the pantograph may accidentally rise when it should not. If the pantograph accidentally rises and touches the high-voltage overhead contact line in a non-working area, it could very likely cause a serious phase-to-phase short circuit or arcing accident, which would not only burn the pantograph plate and the overhead contact line wires, but also seriously threaten the lives of personnel working on the roof.

[0009] According to one embodiment of this application, it further includes: a transition bridge; The transition bridge connects to the end of the first platform away from the staircase, and the transition bridge is used to connect to the first platform of another double-decker platform vehicle for the overhead contact line.

[0010] According to one embodiment of this application, the first platform is provided with guardrails and safety ropes on both sides, the safety ropes are located on the side of the guardrails closer to the pantograph, and the safety ropes are parallel to the guardrails.

[0011] According to one embodiment of this application, a tool cabinet is also included; The tool cabinet is located on the second platform, and a modular tool rack is placed inside the tool cabinet.

Detailed Implementation

[0019] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0020] In the inspection and maintenance of the overhead contact system of electrified railways, the pantograph, as the core component connecting the work vehicle and the contact system, directly affects the reliability of the inspection data and the safety of the workers.

[0021] In actual operation, the pantograph needs to be lowered and kept in a low, non-working state in non-operational areas, such as when the vehicle is parked in different sections or when performing non-contact observation. However, existing double-decker platform vehicles generally have a safety hazard of the pantograph accidentally rising when lowered. When the pantograph accidentally rises in a non-operational area and touches the overhead contact line, it can easily cause a phase-to-phase short circuit or arcing accident, resulting in severe ablation of the pantograph's sliding plate and the overhead contact line conductors, and posing a fatal threat to personnel working on the roof.

[0022] The following is for reference. Figures 1-7 This application describes a double-decker platform vehicle for overhead contact lines according to an embodiment of the present application.

[0023] The double-decker platform vehicle for overhead contact lines includes: a vehicle body 10, a locking door 20, a limiting device 30, and a locking component 40; The vehicle body 10 includes a first platform 11 and a second platform 12, with the first platform 11 located above the second platform 12, and a pantograph 111 disposed on the first platform 11. The locking door 20 is disposed between the first platform 11 and the second platform 12 and is adapted to form a physical barrier to prevent personnel from passing between the first platform 11 and the second platform 12; The limiting device 30 includes a stop part 31 and a fixing part 32. The stop part 31 is movably connected to the fixing part 32. The stop part 31 is used to move to directly above the pantograph 111. The locking member 40 is installed on the stop portion 31 and is adapted to be connected to the fixing portion 32 to hold the stop portion 31 directly above the pantograph 111; The locking member 40 and the locking door 20 are configured such that when the locking member 40 is connected to the fixing part 32, the locking door 20 isolates the first platform 11 and the second platform 12.

[0024] The double-layer platform vehicle for overhead contact lines in the above embodiments of this application ensures that the pantograph 111 is reliably limited to a safe position when not in operation by connecting the locking member 40 to the fixing part 32 of the limiting device 30, effectively preventing accidents caused by the pantograph 111 accidentally rising and touching the high-voltage line. Simultaneously, the locking door 20 can only close and isolate the first platform 11 from the second platform 12 when the pantograph 111 is limited to a safe position, further ensuring operational safety.

[0025] In some embodiments, the limiting device 30 further includes a pin 33 and a pin seat 34; The pin seat 34 is fixedly connected to the fixing part 32, and the pin 33 is elastically installed on the pin seat 34. One end of the pin 33 is adapted to be inserted into the locking member 40 and connected to the locking member 40.

[0026] By introducing the above technical solution, the pin 33 and the pin seat 34 make the connection between the locking member 40 and the fixing part 32 more reliable and convenient. The flexible-installed pin 33 can not only reliably cooperate with the locking member 40 to achieve locking, but also quickly disengage from the locking member 40 after unlocking, improving the flexibility and safety of use.

[0027] In some embodiments, the stop portion 31 is rotatably mounted on the top end of the fixing portion 32, and the locking member 40 is mounted on the end of the stop portion 31 near the fixing portion 32.

[0028] Specifically, the stop part 31 and the fixing part 32 are rotatably mounted. This rotatable mounting allows the stop part 31 to rotate around one or more preset axes, thereby achieving a smooth transition from the storage state to the working state (i.e., located directly above the pantograph 111).

[0029] In some embodiments, a staircase 13 is provided between the first platform 11 and the second platform 12, and handrails 14 are provided on both sides of the staircase 13. The locking door 20 is provided at one end of the staircase 13 near the first platform 11.

[0030] Specifically, the staircase 13 provided between the first platform 11 and the second platform 12 is designed to provide a structured passage for easy access by people to connect the first platform 11 and the second platform 12 at different heights.

[0031] The staircase 13 can be implemented in various forms, such as a fixed staircase 13 with a robust structure that provides a stable passageway; or a foldable or retractable staircase 13 that can be folded away when not needed, saving space and avoiding obstruction of other operations. This application does not limit the specific form of the staircase 13. Furthermore, the tread width, height, and slope of the staircase 13 can all be designed according to ergonomic principles to ensure the comfort and safety of people moving up and down the stairs.

[0032] To further ensure the safety of personnel traversing the staircase 13, handrails 14 are installed on both sides of the staircase 13. The handrails 14 are typically made of sturdy metal materials (such as stainless steel or aluminum alloy) and are securely installed on the staircase 13 structure. The height and diameter of the handrails 14 can be designed according to relevant safety standards to provide stable support and grip points, effectively preventing people from falling due to imbalance while ascending or descending the staircase 13. Especially when vehicles are in motion or the platform is swaying, the handrails 14 can provide crucial auxiliary support.

[0033] In some embodiments, the double-decker platform vehicle for the overhead contact line further includes: a transition bridge 51; The transition bridge 51 is located at the end of the first platform 11 away from the staircase 13, and the transition bridge 51 is used to connect to the first platform 11 of another double-decker platform vehicle for the contact wire.

[0034] Through the above technical solution, this application effectively solves the problems of inconvenience, low efficiency, and safety risks associated with workers moving between different platform vehicles when multiple platform vehicles are operating collaboratively. Specifically, the transition bridge 51 provides a smooth and safe connecting passage, allowing workers to easily and quickly move from the first platform 11 of one platform vehicle to the first platform 11 of an adjacent platform vehicle, thereby achieving seamless expansion of the work area and continuous operation. This connection method not only improves work efficiency and reduces the frequency and time of personnel getting on and off platform vehicles, but also significantly enhances the safety of working at heights, avoiding the risk of falls that may result from crossing or improper movement.

[0035] In some embodiments, guardrails 15 and safety ropes 16 are provided on both sides of the first platform 11. The safety ropes 16 are located on the side of the guardrails 15 closer to the pantograph 111 and are parallel to the guardrails 15.

[0036] Specifically, guardrail 15 is a common safety protection facility, typically constructed of metal rods, mesh, or other sturdy materials. Its height and strength should meet relevant safety standards to effectively prevent workers from falling from the edge of the first platform 11. Safety rope 16 is parallel to guardrail 15, indicating that the direction of safety rope 16 is basically consistent with the direction of guardrail 15.

[0037] Furthermore, lighting and emergency lights are installed alternately on guardrail 15 to ensure sufficient lighting during operation.

[0038] In application, the lighting automatically turns on when the ambient illuminance is below a preset threshold; the emergency light turns on when the lighting fails. Of course, this application does not limit the simultaneous operation of the lighting and the emergency light.

[0039] In some embodiments, the double-decker platform vehicle for overhead contact lines also includes a tool cabinet; The tool cabinet is located on the second platform 12. A modular tool rack is placed inside the tool cabinet. The modular tool rack includes a first support 521, a second support 522, and multiple trays 523. The multiple trays 523 are installed between the first support 521 and the second support 522.

[0040] Through the above technical solutions, when operators need to use specific tools, they can quickly locate and retrieve them, greatly improving work efficiency. At the same time, the orderly storage of tools reduces the risk of tools falling, enhancing operational safety. This modular tool rack design also allows for flexible adjustment of the layout and quantity of trays 523 according to actual work needs, thereby optimizing the space utilization and functionality of the tool cabinet and enabling the platform vehicle to better adapt to diverse overhead contact line maintenance tasks.

[0041] In some embodiments, the double-decker platform vehicle for overhead contact lines also includes a storage compartment 53; The storage room 53 is located on the second platform 12 and at the end of the vehicle body 10. One end of the storage room 53 faces the staircase 13, and sliding doors are provided at one end and the other end of the storage room 53, respectively.

[0042] Through the aforementioned technical solution, a storage room 53 is installed on the double-decker platform vehicle for overhead contact lines, located at the end of the second platform 12 and facing the stairs 13. Equipped with a two-way sliding door, it provides workers with a convenient and centralized storage area for their items. This layout fully utilizes the space of the second platform 12, preventing tools and spare parts from being randomly piled up and occupying the work area, thus effectively improving the cleanliness and safety of the work space. Simultaneously, the design of sliding doors at both ends of the storage room 53 allows workers to easily and quickly access items from any direction, especially when going up or down the stairs 13, eliminating the need for extra detours and greatly improving work efficiency and convenience. This not only reduces the risk of items falling or being lost but also ensures the safe passage of personnel on the platform, making the entire working environment of the double-decker platform vehicle for overhead contact lines more orderly and efficient.

[0043] In some embodiments, the end of the vehicle body 10 is provided with a BSI coupler, which is used to connect to the vehicle body 10 of another adjacent double-layer platform vehicle for overhead contact lines.

[0044] By installing a BSI coupler at the end of the car body 10, and enabling it to connect with the car body 10 of another adjacent double-decker platform vehicle for overhead contact lines, this application allows multiple independent platform vehicles to be conveniently and safely connected into a work group. This significantly improves the efficiency of long-distance overhead contact line maintenance operations, simplifies the scheduling and management of multiple vehicles, and enhances the collaborative capabilities of operators between different platform vehicles.

[0045] This application also proposes a method for using a double-decker platform vehicle for overhead contact lines, including: The locking member 40 is connected to the fixing part 32 to hold the stop end directly above the pantograph 111; Locking door 20 separates the first platform 11 and the second platform 12.

[0046] The double-layer platform vehicle for overhead contact lines in the above embodiments of this application ensures that the pantograph 111 is reliably limited to a safe position when not in operation by connecting the locking member 40 to the fixing part 32 of the limiting device 30, effectively preventing accidents caused by the pantograph 111 accidentally rising and touching the high-voltage line. Simultaneously, the locking door 20 can only close and isolate the first platform 11 from the second platform 12 when the pantograph 111 is limited to a safe position, further ensuring operational safety.

[0047] In some embodiments, a water storage tank is fixed on the vehicle body 10 to provide an independent water source for cleaning operations.
