[0002] The existing straddle-type monorail vehicle signal maintenance platform is a fixed platform, hinged to the floor, and manually rotated 90 degrees. Lowering the platform requires two people: one pushes the platform while the other rotates a drum to lower the wire rope. Retracting the platform involves manually rotating the drum to tighten the wire rope and pull the platform back. This operation is cumbersome, labor-intensive, and the platform, fixed at the front of the driver's cab, occupies considerable space and obstructs the driver's view of the road ahead.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] (like Figure 1 As shown in Figure 9, an engineering vehicle tilting platform includes a vehicle chassis 10 and a vehicle side guardrail 11. The vehicle chassis 10 vertically supports and installs the vehicle side guardrail 11. A drive mechanism is provided at the bottom of the hollow part of the vehicle side guardrail 11. The drive mechanism drives the maintenance platform to tilt back and forth by 90°. The maintenance platform has a base plate 7. The base plate 7 is fixedly connected to the power output end of the drive mechanism, and the base plate 7 is driven by the drive mechanism to tilt back and forth by 90°. The three outer edges of the base plate 7 are respectively hinged to a left side plate 1, a right side plate 6, and a front end plate 3. The left side plate 1, the right side plate 6, and the front end plate 3 can be assembled into a three-dimensional semi-enclosed structure, or laid flat and constrained and fixed to the vehicle side guardrail 12.

[0044] It should be noted that the engineering vehicle's tilting platform has a flexible structure, is easy to operate, safe, has high space utilization, and is suitable for a variety of scenarios.

[0045] Regarding structural flexibility, the three-sided enclosure is deformable: the left side panel 1, right side panel 6, and front panel 3 are hinged, allowing them to be assembled into a semi-enclosed three-dimensional structure (protecting workers from falls) or laid flat and fixed to the vehicle's side guardrail 11. This modular design enhances the platform's adaptability and functionality.

[0046] In terms of ease of operation: One-button drive control: The drive mechanism is integrated into the hollow part of the vehicle's side guardrail. The drive mechanism can use an electric or hydraulic system to realize the automated flipping of the maintenance platform, reducing manual operation intensity and shortening the preparation time. Quick unfolding / storage: Whether the left side panel 1, right side panel 6, and front panel 3 form a three-dimensional semi-enclosed structure or are laid flat, it can be completed by a single person without complicated tools, making it suitable for emergency repairs or high-frequency operation scenarios.

[0047] Regarding safety: A semi-enclosed protective structure: During operation, the left side panel 1, right side panel 6, and front panel 3 form a three-dimensional semi-enclosed structure, effectively preventing tools or personnel from falling, especially suitable for high-altitude or edge-operating environments. A stable fixing mechanism: When laid flat, the left side panel 1, right side panel 6, and front panel 3 are constrained and fixed to the vehicle's side guardrail 11, preventing shaking or displacement and ensuring storage stability. Optimized structural strength: The base plate 7 is fixedly connected to the power output end of the drive mechanism, improving the platform's load-bearing capacity.

[0048] In terms of space utilization, when the left side panel 1, right side panel 6, and front panel 3 are stored vertically, they do not occupy additional space, making them suitable for use in narrow work areas such as those crossing bridges or tunnels. They also offer multi-functionality; when the left side panel 1, right side panel 6, and front panel 3 are assembled into a maintenance platform, the working area can be expanded or used as a temporary material storage area, improving the overall utilization rate of the vehicle.

[0049] In terms of wide applicability, it is compatible with multiple industries: suitable for equipment inspection, installation and maintenance in fields such as power, communications, municipal administration, and transportation, especially in scenarios that require frequent changes in work location or space.

[0050] As can be seen, the tilting platform of this embodiment achieves a balance between safety, flexibility and efficiency through structural innovation and functional integration. It is especially suitable for engineering vehicles with high requirements for space utilization and operational safety, and has a significant competitive advantage in the market.

[0051] In the above embodiments, preferably: the driving mechanism is a rotary cylinder 9; the rotary cylinder 9 is fixedly connected to the vehicle chassis 10 by rotary cylinder fixing bolts 901; the power output end of the rotary cylinder 9 is provided with a rotary cylinder flange 8, the rotary cylinder flange 8 is concentrically fixedly connected to the base plate flange 701, and the base plate flange 701 is fixedly connected to the base plate 7 to realize the 90° reciprocating flipping of the base plate 7.

[0052] It should be noted that: this embodiment uses a rotary cylinder 9 as the driving mechanism, and achieves 90° reciprocating rotation of the base plate 7 through a flange connection structure. It has excellent power performance and stable and reliable rotation; the flange connection structure transmits torque efficiently and safely; the structure is compact and has high space utilization; maintenance is convenient and cost is controllable; and it has strong environmental adaptability.

[0053] In terms of power performance, the rotary cylinder 9 is hydraulically driven, providing high torque output, making it particularly suitable for tilting heavy maintenance platforms (including those carrying tools and personnel), preventing jamming or shaking due to insufficient power. The hydraulic system of the rotary cylinder 9 allows for stepless speed regulation and angle positioning, ensuring the base plate 7 tilts smoothly within a 90° range, reducing impact loads, extending structural lifespan, and achieving precise angle control. The hydraulic system includes a safety valve to prevent damage to the drive mechanism due to overload or accidental jamming, improving operational safety and providing overload protection.

[0054] In terms of efficient and safe torque transmission via flange connections, the rotary cylinder flange 8 and the base plate flange 701 are concentrically bolted together, ensuring an unbiased power transmission path and preventing vibration or flange loosening caused by uneven torque transmission. The flange connection surfaces of the rotary cylinder flange 8 and the base plate flange 701 are precision-machined and equipped with high-strength bolts, capable of withstanding shear forces and tensile stresses during the flipping process, ensuring long-term durability. Modular replacement: The flange connection structure of the rotary cylinder flange 8 and the base plate flange 701 facilitates the disassembly and replacement of the base plate 7 or the rotary cylinder 9, reducing maintenance complexity.

[0055] In terms of compact structure and space utilization, the rotary cylinder 9 is directly fixed to the vehicle chassis 10 by rotary cylinder fixing bolts 901. The vertical installation method reduces the horizontal space occupation and avoids interference with other vehicle components. The rotary cylinder 9 is placed in the hollow part of the vehicle side guardrail 11, which not only protects the cylinder from external impacts but also keeps the vehicle's appearance clean, in line with the trend of compact design for engineering vehicles.

[0056] In terms of ease of maintenance and cost control, the rotary cylinder 9 uses a standard hydraulic interface, making it compatible with the vehicle's existing hydraulic system (such as hydraulic pumps and oil tanks), reducing the need for additional power sources and lowering procurement and maintenance costs. Hydraulic drive components have a lower wear rate than mechanical transmission components, resulting in lower long-term maintenance costs and making them suitable for high-frequency operation scenarios.

[0057] Regarding environmental adaptability, the rotary cylinder 9, rotary cylinder flange 8, and base plate flange 701 can be galvanized or powder-coated to adapt to harsh environments such as humidity and salt spray, extending their service life. Hydraulic oil with good low-temperature fluidity can be selected to ensure normal start-up and rotation even in low-temperature environments (such as -30℃). The hydraulic system's buffering characteristics can absorb some external impact forces, protecting the drive mechanism and platform structure, making it suitable for rough operation scenarios.

[0058] As can be seen, the tilting platform of this embodiment achieves a high-efficiency, reliable, and compact design of the drive mechanism through the selection of the rotating cylinder 9 and the combination of the rotating cylinder flange 8 and the base plate flange 701 connection structure, which is especially suitable for engineering vehicles with high requirements for power performance, space utilization and maintenance convenience.

[0059] In the above embodiments, further: the left side plate 1 is hinged to the left side of the base plate 7 via connecting hinge I2, the right side plate 6 is hinged to the right side of the base plate 7 via connecting hinge II5, and the front end plate 3 is hinged to the outside of the base plate 7 via connecting hinge III4; when the left side plate 1, right side plate 6, and front end plate 3 are assembled into a three-dimensional semi-enclosed structure, the left side plate 1, right side plate 6, and front end plate 3 are fastened by fasteners 12; when the left side plate 1, right side plate 6, and front end plate 3 are laid flat, the left side plate 1 is constrained and fixed to the left side of the vehicle side guardrail 11 via left side plate fixing bolts 13, the right side plate 6 is constrained and fixed to the right side of the vehicle side guardrail 11 via right side plate fixing bolts 14, and the front end plate 3 is constrained and fixed to the outside of the base plate 7 via front end plate fixing bolts 15, and the left side plate 1 and right side plate 6 are parallel to the vehicle side guardrail 11, and the front end plate 3 is parallel to the base plate 7.

[0060] It should be noted that in this embodiment, the engineering vehicle tilting platform is hinged together by connecting hinge I2, connecting hinge II5, and connecting hinge III4, and secured by left side plate fixing bolt 13, right side plate fixing bolt 14, and front plate fixing bolt 15. This allows for flexible switching between a three-dimensional semi-enclosed structure and a flat unfolded state, resulting in a stable structure with high load-bearing capacity; convenient operation and efficient switching; excellent spatial adaptability; upgraded safety protection; economical maintenance; and a long service life.

[0061] Regarding structural stability and load-bearing capacity, hinges I2, II5, and III4 are used for hinge connection. These hinges are made of high-strength steel with a thickened design, capable of withstanding the shear forces and bending stresses from frequent flipping, preventing loosening or deformation after long-term use. The hinge points are rationally distributed (e.g., 2-3 hinges are evenly arranged on the left side of the left plate 1 on the left side of the base plate 7), ensuring uniform stress distribution at the connection between the left plate 1 and the base plate 7, reducing local stress concentration, and improving the overall structural lifespan. A three-dimensional semi-enclosed structure is achieved: the three-sided enclosure consisting of the left plate 1, right plate 6, and front plate 3 is tightly connected by fasteners 12 (such as quick-lockers or bolts + nuts), effectively resisting lateral forces during operation (such as wind loads and tool collisions), preventing the enclosure from flipping outwards or deforming. In the unfolded state: the left side plate 1 and the right side plate 6 are rigidly connected to the vehicle side guardrail 11 by the left side plate fixing bolt 13 and the right side plate fixing bolt 14, and the front plate 3 is attached and fixed to the bottom plate 7 by the front plate fixing bolt 15, forming a stable planar structure to avoid displacement of the left side plate 1, the right side plate 6 and the front plate 3 due to vibration.

[0062] In terms of ease of operation and switching efficiency, the hinged design allows the left side panel 1, right side panel 6, and front panel 3 to switch states through simple push-pull or flip actions, without the need for complex tools or multiple people working together. For example, switching from a flat state to a three-dimensional structure can be completed by a single person.

[0063] In terms of excellent spatial adaptability to meet diverse needs, when laid flat, the left side panel 1 and right side panel 6 are parallel to and attached to the vehicle's side guardrail 11, and the front panel 3 is parallel to and attached to the base panel 7. The overall thickness is only increased by the hinge height, taking up almost no extra space, making it suitable for use in narrow work areas. In three-dimensional form, the height of the enclosure composed of the left side panel 1, right side panel 6, and front panel 3 can be designed according to operational needs (e.g., 1.2-1.5m), providing sufficient protection while avoiding excessive height that could affect the vehicle's center of gravity stability.

[0064] Regarding safety performance, the semi-enclosed design of the engineering vehicle tilting platform effectively prevents personnel, tools, or materials from falling from the side or front, making it suitable for high-altitude operations (such as bridge inspection) and meeting the requirements of standards such as the "Technical Specification for Safety of High-Altitude Operations in Construction" (JGJ80). When the engineering vehicle tilting platform is laid flat to prevent displacement, the left side plate fixing bolt 13, right side plate fixing bolt 14, and front end plate fixing bolt 15 are designed to prevent loosening, such as by adding spring washers, to prevent the left side plate 1, right side plate 6, and front end plate 3 from loosening due to vehicle movement or operational vibrations, ensuring structural stability.

[0065] In terms of maintenance economy and lifespan, the left side plate 1, right side plate 6, and front end plate 3 are all connected to the bottom plate 7 via independent hinges. When damaged, individual left side plate 1, right side plate 6, front end plate 3, or hinges can be replaced locally, eliminating the need for complete replacement and reducing maintenance costs. Fasteners 12 and the left side plate fixing bolts 13, right side plate fixing bolts 14, and front end plate fixing bolts 15 can use standardized models for quick procurement and replacement, reducing downtime. The surfaces of left side plate 1, right side plate 6, front end plate 3, connecting hinges I 2, II 5, III 4, and the left side plate fixing bolts 13, right side plate fixing bolts 14, and front end plate fixing bolts 15 are galvanized, powder-coated, or treated with Dacromet coating to withstand harsh environments such as humidity and salt spray, extending their service life to over 10 years.

[0066] In the above embodiment, the holes on the left side plate 1 and the right side plate 6 for fixing the vehicle side guardrail 11 are the same set of holes 17 as the holes on the left side plate 1 and the right side plate 6 for fixing the front end plate 3.

[0067] It should be noted that this embodiment adopts a hole reuse design, with the same set of holes 17 simultaneously serving two connection functions (left side plate 1, right side plate 6 and vehicle side guardrail 11, front end plate 3 and bottom plate 7). This avoids the need for additional holes or connectors on the left side plate 1, right side plate 6 and front end plate 3, significantly reducing structural redundancy. It also avoids local stress concentration caused by multiple holes, and can further reduce weight while ensuring strength, thereby improving vehicle fuel economy or electric range.

[0068] Furthermore, the same set of holes 17 can achieve dual functions through different connection methods (such as bolts + nuts, quick-release pins), eliminating the need for repeated positioning or tooling switching during assembly. A single person can quickly complete the operation, shortening preparation time. The size and spacing of holes 17 can be standardized to a uniform specification, compatible with various connectors, reducing spare parts management costs, and adapting to the rapid modification needs of different scenarios.

[0069] Furthermore, reducing the number of holes directly lowers the processing costs of the left side plate 1 and the right side plate 6. Since the connectors for the same set of holes 17 are of a uniform type, only one type of bolt or pin needs to be stocked for maintenance, reducing the variety of spare parts and inventory pressure. If a hole is damaged, only that hole needs to be repaired or replaced, rather than the entire left side plate 1, right side plate 6, front end plate 3, or connecting structure, significantly reducing maintenance costs.

[0070] Regarding stress distribution and connection stability, the existing porous design tends to cause localized stress concentration in the left side plate 1, right side plate 6, and front end plate 3, especially during frequent flipping or when bearing heavy loads, potentially leading to cracks or deformation. This solution reuses the hole positions of hole 17, concentrating the connection stress within the same group of holes 17, and improves overall fatigue resistance by optimizing hole spacing and stress distribution. The dual connection function of the same group of holes 17 can be enhanced with design redundancy (such as increasing hole wall thickness or using high-strength bolts). For example, in a three-dimensional configuration, hole 17 simultaneously bears the tensile force of the front end plate 3 and the shear force of the side guardrail 11. By optimizing the hole layout through structural simulation, it can be ensured that the superposition of these two forces does not exceed the material's yield strength.

[0071] As can be seen, this embodiment achieves dual connection functionality through the same set of holes 17. This embodiment achieves breakthrough optimizations in terms of structural compactness, functional integration, cost-effectiveness, and reliability. Its core advantage lies in "simplifying complexity" by reducing redundant design, thereby improving the platform's adaptability and ease of maintenance, and possessing significant market application value.

[0072] In the above embodiment, it further includes a fixing block 16, which is respectively disposed on the vehicle side guardrail 11 and the base plate 7. The fixing block 16 is provided with bolt holes, which are respectively used to screw and connect the left side plate fixing bolt 13, the right side plate fixing bolt 14, and the front end plate fixing bolt 15.

[0073] It should be noted that this embodiment achieves a significant increase in structural reliability and load-bearing capacity by adding a fixing block 16; it also improves assembly precision, further optimizes operational convenience, and enhances maintenance ease.

[0074] In terms of significantly enhanced structural reliability and improved load-bearing capacity, the fixing block 16, acting as an independent connector, distributes the fixing force of the left side plate 1, right side plate 6, and front end plate 3 over a larger area of ​​the vehicle side guardrail 11 and the base plate 7 via bolt holes, rather than directly acting on the thin-walled structure (such as the surface of the vehicle side guardrail 11 or the base plate 7). Traditional designs might directly screw the left side plate fixing bolt 13, right side plate fixing bolt 14, and front end plate fixing bolt 15 into the thin steel plate of the vehicle side guardrail 11, which can easily lead to tearing of the hole walls due to vibration after long-term use. This solution, through the fixing block 16, transfers stress to the reinforcing ribs of the vehicle side guardrail 11 or the frame structure of the base plate 7, significantly improving tensile and shear resistance.

[0075] Regarding assembly precision, the bolt holes of the fixing block 16 are precision-machined, with hole diameters and spacing strictly matching the specifications of the left side plate fixing bolt 13, right side plate fixing bolt 14, and front end plate fixing bolt 15. This ensures quick alignment and blind installation of the left side plate 1, right side plate 6, and front end plate 3 with the vehicle side guardrail 11 and base plate 7. During assembly, the operator only needs to align the bolt holes of the fixing block 16, insert the bolts, and tighten them. There is no need to repeatedly adjust the position, and a single person can complete the state switch within 5 minutes. As a standardized component, the fixing block 16 can be uniformly applied to different models of engineering vehicles or work platforms. Only the dimensions (such as thickness) of the fixing block 16 need to be adjusted to adapt to the structural differences between the vehicle side guardrail 11 and base plate 7.

[0076] In terms of improved ease of operation and reduced life-cycle costs, the fixing block 16 can be partially replaced, reducing maintenance difficulty. If the fixing block 16 wears or is damaged due to long-term use (such as stripped bolt holes), only the fixing block 16 needs to be removed and replaced, without needing to repair the fixing block 16 or the base plate 7, significantly reducing maintenance time and material costs. For example, in traditional designs, bolt holes are directly drilled into the vehicle side guardrail 11 and the base plate 7, requiring cutting or welding repair after damage. However, this solution only requires loosening the connecting bolts of the fixing block 16 for quick replacement, reducing maintenance difficulty. The fixing block 16 can be made of corrosion-resistant materials (such as stainless steel or galvanized steel) or surface treatment processes (such as powder coating or Dacromet coating) to adapt to harsh environments such as humidity and salt spray, avoiding bolt jamming or reduced hole wall strength due to rust. For example, in engineering vehicles used in coastal areas, the anti-corrosion treatment of the fixing block 16 can extend its lifespan to more than 10 years, reducing total life-cycle maintenance costs.

[0077] As can be seen, by adding the fixing block 16 and optimizing its bolt hole design, this embodiment achieves a comprehensive upgrade in terms of structural reliability, assembly accuracy, and ease of maintenance. Its core advantage lies in "strengthening connection reliability with the independent component of the fixing block 16 and improving versatility with standardized design," making it particularly suitable for engineering vehicles where safety and efficiency requirements are high.

[0078] In the above embodiments, preferably, the connecting hinge I2, connecting hinge II5, and connecting hinge III4 are damped hinges.

[0079] It should be noted that in this embodiment, connecting hinge I2, connecting hinge II5, and connecting hinge III4 are preferably damped hinges. This improvement has significant technical advantages in terms of operational safety, structural stability, reduction of vibration and noise, improvement of equipment life and user experience.

[0080] Regarding operational safety, traditional undamped hinges, when the front panel 3 flips, will rapidly fall or bounce due to gravity, causing operators to be caught and injured before they can react. Damped hinges, however, control the flipping speed of the left side panel 1, right side panel 6, and front panel 3, allowing for a slow and smooth transition between states. When the front panel 3 is flattened from its three-dimensional position, the damped hinge resists gravity, preventing it from rapidly impacting the base plate 7, reducing the risk of operators getting their hands caught. This is especially suitable for use in confined spaces or at heights, while also preventing impact damage to the front panel 3. In the field of engineering vehicles, operational safety is a core indicator. Damped hinges effectively reduce accidents (such as pinching, crushing, and equipment damage) caused by uncontrolled flipping of the left side panel 1, right side panel 6, and front panel 3, meeting the requirements of international safety standards such as ISO 12100 (General Rules for Safety Design of Machinery) and enhancing product market competitiveness.

[0081] In terms of structural stability and reducing vibration and noise, during the operation of the engineering vehicle, chassis vibration is transmitted through the hinges to the left side panel 1, right side panel 6, and front panel 3, causing them to sway or generate noise, affecting the operator's concentration. Damped connecting hinges I2, II5, and III4 absorb and attenuate vibration energy, significantly reducing vibration transmission between the left side panel 1, right side panel 6, front panel 3, and the vehicle body. Traditional hinges produce a harsh metallic friction sound when flipping or vibrating (especially at low temperatures or with insufficient lubrication), while damped connecting hinges I2, II5, and III4 effectively reduce noise levels through built-in lubrication structures (such as self-lubricating bearings) and damping materials (such as silicone or rubber gaskets). Tests have shown that damped hinges can reduce the flipping noise of the left side panel 1, right side panel 6, and front panel 3 from 80 decibels to below 50 decibels, meeting occupational health and safety standards (such as OSHA's noise exposure limits) and protecting the operator's hearing.

[0082] In terms of extending equipment lifespan and reducing maintenance costs, damped hinges reduce mechanical impact and delay component wear. Damped hinges significantly reduce mechanical stress damage to components by buffering the impact of tipping. Experimental data shows that using damped hinges can reduce hinge shaft wear by more than 70%, reduce the frequency of loosening connecting bolts by 50%, and reduce the risk of cracking at the connection points between the left side plate 1, right side plate 6, front end plate 3, and the hinge by 90%. In high-frequency usage scenarios, damped hinges can extend the overall lifespan of the left side plate 1, right side plate 6, and front end plate 3 system from 3 years to more than 8 years, significantly reducing the total lifespan maintenance cost. In desert or high-humidity environments, traditional hinges require monthly lubrication, while damped hinges can achieve "maintenance-free" operation, reducing downtime for maintenance. In low-temperature regions (below -20℃), low-viscosity hydraulic oil can be used for damped hinges to ensure normal operation at low temperatures and prevent hinge jamming or failure.

[0083] In terms of user experience optimization and improved ease of operation, traditional undamped hinges require operators to use both hands to control the rotation speed of the side panels (left side panel 1, right side panel 6, front panel 3), such as holding the side panel with one hand and adjusting the angle with the other. Damped connecting hinges I2, II5, and III4, however, can automatically balance the weight of the side panels (left side panel 1, right side panel 6, front panel 3) through damping force, achieving the effect of "rotating with a light push of one hand." For female operators or those with less physical strength, the damped connecting hinges I2, II5, and III4 significantly reduce the difficulty of operation, reflecting a human-centered design. The slow rotation characteristic of the damped hinges allows the side panels (left side panel 1, right side panel 6, front panel 3) to automatically decelerate as they approach the target position, facilitating precise alignment of the bolt holes of the fixing block 16 by the operator.

[0084] It is evident that designing connecting hinges I2, II5, and III4 as damped hinges significantly improves the safety, stability, and durability of the engineering vehicle tilting platform by buffering the impact of tipping, suppressing vibration transmission, reducing mechanical wear, and optimizing the user experience. Its core advantage lies in "actively preventing accidents through passive safety design and enhancing the user experience through refined damping control," making it particularly suitable for the engineering vehicle sector, where safety and efficiency are paramount.

[0085] This invention also claims protection for a method of using a construction vehicle tilting platform, wherein the construction vehicle tilting platform is any of the aforementioned construction vehicle tilting platforms, and the method of using the construction vehicle tilting platform includes the following steps:

[0086] S1. Assembly: During use, the maintenance platform is quickly assembled inside the vehicle; the left side plate 1, right side plate 6, and front end plate 3 are fastened together with fasteners 12 to form a semi-enclosed structure, which, together with the base plate 7, forms the maintenance platform. (e.g.) Figure 11 (As shown)

[0087] S2. Tilting: The drive mechanism rotates 90° outwards, making the bottom plate 7 of the maintenance platform flush with the vehicle chassis 10. Maintenance personnel enter the maintenance platform and work under the protection of the semi-enclosed structure. (e.g.) Figure 12 (As shown)

[0088] S3. Retraction: After the work is completed, the maintenance personnel return from the base plate 7. The drive mechanism rotates inward 90° to retract the maintenance platform, ensuring that the base plate 7 of the maintenance platform is in a vertical position. (e.g.) Figure 11 (As shown)

[0089] S4. Reset: Remove fastener 12, unfold the left side plate 1 and right side plate 6 by 90° to the left and right respectively, and then fix the left side plate 1 and right side plate 6 to the vehicle side guardrail 11; flip the front end plate 3 inward by 90° and then fix it to the base plate 7. (e.g.) Figure 10 (As shown)

[0090] It should be noted that the method of using the engineering vehicle tilting operation platform of the present invention, through modular assembly, multi-state switching and compact storage design, combined with core advantages such as safety protection, ease of operation and space optimization, significantly improves the operating efficiency and safety of engineering vehicles in inspection and maintenance scenarios.

[0091] In step S1 (assembly), the left side plate 1, right side plate 6, and front end plate 3 are fixed together as a semi-enclosed structure by fasteners 12 (such as bolts), and together with the base plate 7, they form a maintenance platform. The modular design allows the platform to be quickly assembled inside the vehicle, which is especially suitable for emergency maintenance scenarios.

[0092] Step S2 (Flipping): The drive mechanism (such as the rotary cylinder 9) rotates 90° outwards, making the base plate 7 flush with the vehicle chassis 10, forming a horizontal and stable working surface. After the base plate 7 is flush with the vehicle chassis 10, maintenance personnel can walk smoothly, avoiding tripping or tool slippage due to height differences. A suitable drive mechanism should be selected based on the platform weight to ensure a smooth and unobstructed flipping process, while avoiding structural deformation due to excessive driving force. In the maintenance state of Step S2, the left side plate 1, right side plate 6, and front plate 3 form a semi-enclosed barrier to prevent maintenance personnel from falling out of the vehicle. The enclosed design of the semi-enclosed structure reduces the fear of working at heights, especially suitable for beginners or those with a fear of heights, improving work focus. In the working state of Step S2, the surface of the base plate 7 can be covered with anti-slip rubber mats or have a textured design to prevent maintenance personnel from slipping on oil or rainwater.

[0093] Step S3 (Retraction): The drive mechanism rotates inward 90°, restoring the base plate 7 to a vertical position and reducing the platform's space occupation. The vertically positioned base plate 7 is parallel to the vehicle, saving space. The drive mechanism can integrate a mechanical self-locking or electromagnetic lock to prevent the platform from automatically unfolding due to vibration during driving, improving safety.

[0094] Step S4 (Reset): After removing fastener 12, the left side panel 1 and right side panel 6 are laid flat and unfolded 90° to the left and right respectively, and fixedly secured to the vehicle side guardrail 11; the front panel 3 is flipped inward 90° and fixedly secured to the base plate 7. Physical fixation ensures that the reset left side panel 1, right side panel 6, and front panel 3 will not be accidentally unfolded due to vehicle bumps or inertia, avoiding scratches to surrounding personnel or equipment. In the reset state of Step S4, the platform has a small thickness when laid flat or folded, effectively freeing up space.

[0095] Furthermore, the platform can be deployed and retracted using a single drive mechanism, allowing maintenance personnel to switch states with just one button, thus avoiding confusion or omissions caused by multiple steps.

[0096] In the above embodiments, preferably, the driving mechanism is a rotary hydraulic cylinder 9. The preferred driving mechanism in this embodiment is the rotary hydraulic cylinder 9, and its technical advantages have been described above and will not be repeated here.

[0097] The present invention also claims protection for the application of an engineering vehicle tilting platform, wherein the engineering vehicle tilting platform is any one of the engineering vehicle tilting platforms described in the present invention, and the engineering vehicle tilting platform is applied to a straddle-type monorail engineering vehicle.

[0098] It should be noted that straddle-type monorail engineering vehicles typically use elevated tracks, resulting in limited interior space. The tilting operation platform of this invention minimizes the impact on vehicle space through its compact structural design. Straddle-type monorail vehicles use guide wheels and stabilizing wheels to encircle the track, ensuring operational safety. This invention's tilting operation platform adopts a similar design, enhancing operational safety through physical barriers. Multi-adaptive medium-capacity straddle-type monorail vehicles employ automatic driving technology, enabling automatic wake-up, start-stop, and return-to-depot functions. This invention's tilting operation platform can adopt similar logic, improving operational efficiency through automated control. Straddle-type monorail engineering vehicles are commonly used in extreme environments such as high temperatures, extreme cold, and high altitudes. This invention's tilting operation platform uses corrosion-resistant and impact-resistant materials to ensure stable operation under harsh conditions.

[0099] The various embodiments in this specification are described in a related manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0100] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are included within the scope of protection of the present invention.
