[0050] The position of the worktable of the straddle-type monorail work vehicle maintenance platform is adjusted by using an electric drive component to drive the moving part to move relative to the fixed part. The worktable is used for operators to stand or place tools, etc. The worktable is located on the moving part and changes position as the moving part moves. The electric drive unit, driven by electrical signals, offers advantages over hydraulic drives, including easier control, faster response, and more precise position control.

This allows operators to easily and quickly position the maintenance platform precisely to the required working position on the track or third rail, thus increasing maintenance efficiency. Furthermore, compared to existing straddle-type monorail engineering vehicle maintenance platforms that use multiple independent hydraulic systems connected in series or stacked to change the platform's position, the solution provided in this embodiment reduces complex components such as hydraulic pump stations, oil circuits, and valve groups, resulting in a more compact overall structure.

Detailed Implementation

[0072] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0073] like Figure 1 and Figure 2 As shown, this application provides an embodiment of a straddle-type monorail work vehicle maintenance platform. This maintenance platform is installed at the bottom 1 of the carriage, and operators perform maintenance work on the platform. The straddle-type monorail work vehicle maintenance platform includes a fixed support 2, a lower support lifting component 4 with a working area, and an outward tilting component 100. The fixed support 2 is provided with a first drive unit 201 and is movably mounted with an upper support telescopic component 3. The first drive unit 201 drives the upper support telescopic component 3 to move laterally, and the first drive unit 201 is installed on the horizontal center line of the fixed support 2. The lower support lifting component 4 is movably mounted on the upper support telescopic component 3. A second drive unit 9 is installed on the upper support telescopic component 3, and the second drive unit 9 drives the lower support lifting component 4 to move longitudinally. The outward tilting component 100 is hinged to the lower support lifting component 4 to increase the working area.

[0074] When in use, the fixed bracket 2 is bolted to the bottom of the carriage 1 to support the weight of the entire straddle-type monorail work vehicle maintenance platform. The operator stands in the work area and starts the first drive unit 201 and the second drive unit 9 to switch the position of the lower support lifting component 4, unfolding the outward flipping component 100 to expand the work area and improve safety. At the same time, the operator must wear a safety rope as required.

[0075] In some embodiments, a straddle-type monorail work vehicle maintenance platform is specifically designed as follows;

[0076] As attached Figure 1 As shown, in this embodiment, a guide rail module 13 is installed between the upper support telescopic part and the fixed support 2. The guide rail module 13 is a combination of guide rail and slider, which is the prior art and will not be described in detail here; the output end of the first drive part 201 is connected to the upper support telescopic part.

[0077] Matching Figure 2 The first drive unit 201 here includes a gear 22 and rack 21 module and a servo motor 23; the gear 22 and rack 21 module includes a gear 22 and a rack 21 that are meshed together, the servo motor 23 is fixed on the fixed bracket 2, a reducer 24 is installed between the servo motor 23 and the gear 22, the rack 21 is fixedly connected to the upper bracket telescopic component 3, and the servo motor 23 is used to provide power for the extension and retraction of the upper bracket telescopic component 3.

[0078] Reference Appendix Figure 2 and Figure 3In this embodiment, a guide assembly 14 is installed between the lower support lifting component 4 and the upper support telescopic component 3. The guide assembly 14 is multi-stage adjustable. According to the actual height on site, two-stage adjustment is sufficient to meet the usage requirements. The guide assembly 14 includes a first guide rail 31 and a second guide rail 33. A first slider 32 is slidably installed on the first guide rail 31, and a second slider 34 is slidably installed on the second guide rail 33. The first slider 32 and the second slider 34 are fixed together by a connector 35. The first guide rail 31 is fixedly connected to the upper support telescopic component 3, and the second guide rail 33 is fixedly connected to the lower support lifting component 4.

[0079] In this embodiment, the second drive unit 9 uses an existing screw jack. The screw jack is installed between the upper support telescopic component 3 and the lower support lifting component 4 to provide power for the lifting movement of the lower support lifting component 4. Its fixed end is installed and connected to the upper support telescopic component 3, and its moving end is connected to the lower support lifting component 4 to realize the lifting movement of the lower support lifting component 4.

[0080] As attached Figure 1 and Figure 4 As shown, the outward tilting component 100 includes a primary outward tilting component 5 and a secondary outward tilting component 6. The primary outward tilting component 5 and the secondary outward tilting component 6 are hinged together. The primary outward tilting component 5 is hinged to the lower support lifting component 4. An electric push cylinder 10 is hinged between the primary outward tilting component 5 and the lower support lifting component 4. A balancer 11 is connected between the lower support lifting component 4 and the primary outward tilting component 5 to balance part of the weight of the outward tilting component 100, provide some assistance when the outward tilting platform is retracted, enhance the balance of the outward tilting component 100 during movement, and also reduce the pulling force and power of the electric push cylinder 10 required. In actual installation, the secondary outward tilting component 6 is connected to the primary outward tilting component 5 through a damping hinge to further expand the operating space on the straddle-type monorail work vehicle maintenance platform. A foldable guardrail is installed on this component to ensure the safety of the operator. When the operator needs to perform external operations, the secondary outward tilting component 6 must be manually flattened and the edge guardrail unfolded before the operation can be carried out.

[0081] This embodiment also adds an inward flipping component 7. The inward flipping component 7 and the outward flipping component 100 are arranged opposite each other on both sides of the lower support lifting component 4. The inward flipping component 7 and the lower support lifting component 4 are hinged and driven by electric push cylinders 10. The two electric push cylinders 10 are arranged crosswise in the space. It is worth mentioning that the inward flipping component 7 has a mounting cavity, in which a pull-out plate is installed and limited. This is used to further expand the passable space on the straddle-type monorail work vehicle maintenance platform. When the operator needs to pass under the track, the inner pull-out plate 8 needs to be manually pulled out and fixed. In the actual design, the inner pull-out plate 8 is designed as a "wedge". During the pulling of the inner pull-out plate 8, it is until the inner pull-out plate 8 is stuck by the cavity opening. This makes it easy to fix and retract the inner pull-out plate 8.

[0082] Limit switches are installed at the extreme positions of the movement stroke of each moving part in the platform. After each part moves to its position, the pin is inserted manually to fix the relative position of the moving part. The platform's electrical control box 12 is fixed on the telescopic component 3 of the upper support. A steel ladder 15 is installed on the maintenance platform so that personnel above the vehicle can enter the maintenance platform.

[0083] In practical use, operators descend from the train to the work area via a ladder, wearing safety harnesses. They then drive the electric cylinder 10 to open the first-stage outward-folding component 5 and manually open the second-stage outward-folding component 6. Driven by the servo motor 23 and the screw jack, the lower support lifting component 4 is switched in the plane to perform maintenance work on the bottom of the train. In actual manufacturing, each maintenance platform is equipped with two lights and two fire extinguishers. A buzzer is installed on the maintenance platform to warn operators to pay attention to safety when the maintenance platform is in operation.

[0084] like Figure 6 As shown, in addition to the straddle-type monorail maintenance platform described above, this embodiment of the invention also provides another straddle-type monorail maintenance platform. This straddle-type monorail maintenance platform includes a fixed component, a movable component, and an electric drive component. The fixed component is used to connect to the vehicle body; the movable component is directly or indirectly connected to the fixed component and can move relative to the fixed component; the output end of the electric drive component is connected to the movable component, and the fixed end of the electric drive component is used to connect to the vehicle body or directly or indirectly connected to the fixed component, for driving the movable component to move along a preset trajectory.

[0085] It should be noted that the fastener is a mounting base or support component used to fix it to the body of the engineering vehicle, serving as the load-bearing foundation for the entire maintenance platform. The fastener is used to bear the moving parts and operational loads. In some embodiments, the fastener can also provide a guiding foundation for the movement of the moving parts. In addition, the fastener can be an independent mounting structure, or it can be a vehicle chassis, subframe, or mounting beam, etc.

[0086] A movable component is a functional part that performs motion. It can undergo displacement or posture changes relative to a fixed component to achieve flexible adjustment of its spatial position and reduce blind spots in operation. The movable component can be directly connected to the fixed component or indirectly connected through an intermediate component, as long as the movable component has relative motion with respect to the fixed component. Furthermore, movable components are not limited to single moving parts; they can also include multi-stage moving parts, linked parts, or combined moving parts. For example, a movable component can include a first movable component and a second movable component. The first movable component is directly connected to the fixed component to achieve a first motion. The second movable component is connected to the first movable component and can perform a second motion relative to the first movable component. That is, the second movable component is indirectly connected to the fixed component through the first movable component. When the second movable component performs a second motion relative to the first movable component, its position relative to the fixed component also changes.

[0087] An electric drive component is a power element driven by an electrical signal. It is used to provide motion driving force for moving parts. Its output end is connected to the moving part, and its fixed end is connected to the vehicle body or a fixed part. The electric drive component can be an electric push rod, an electric lift, an electric cylinder, a lead screw drive mechanism, or other electric actuators.

[0088] The term "electrically driven moving part moving along a preset trajectory" means that the moving part does not move without constraints, but rather moves according to a preset motion path under the drive of the electric drive. Furthermore, this embodiment does not limit the specific direction of the preset trajectory motion; that is, it does not limit the direction or form of the moving part's movement relative to the fixed part. For example, the preset trajectory motion can be linear motion, curvilinear motion, or flipping motion in any direction.

[0089] In other words, this embodiment uses an electric drive component to drive the movable component to move relative to the fixed component, thereby realizing the position adjustment of the work platform of the straddle-type monorail work vehicle maintenance platform. The work platform is used for operators to stand or place tools, etc. The work platform is located on the movable component and changes position as the movable component moves. The electric drive unit, driven by electrical signals, offers advantages over hydraulic drives, including easier control, faster response, and more precise position control. It enables precise displacement control of moving parts, improving accuracy and convenience. This allows operators to easily and quickly position the maintenance platform precisely to the required working position on the track or third rail, thus increasing maintenance efficiency. Furthermore, compared to existing straddle-type monorail engineering vehicle maintenance platforms that use multiple independent hydraulic systems connected in series or stacked to change the platform's position, the solution provided in this embodiment reduces complex components such as hydraulic pump stations, oil circuits, and valve groups, resulting in a more compact overall structure. This reduces the number of parts and assembly complexity, thereby lowering manufacturing and maintenance costs. Moreover, the electric drive unit eliminates or reduces hydraulic transmission links, minimizing potential failure points and preventing issues such as hydraulic leakage, pressure fluctuations, and jamming, thus improving the overall reliability and service life of the maintenance platform. In addition, the use of electric drive components makes the moving parts highly adaptable to space, which is conducive to adapting to the maintenance needs of different spatial positions such as track beams and third rails, and improving the operation coverage in complex spatial environments. Furthermore, the electric drive components can be further combined with position sensors, encoders and control systems to realize automatic positioning, linkage control, remote control or intelligent anti-collision control, which is conducive to improving the intelligence level of the maintenance platform.

[0090] like Figure 6 and Figure 7As shown, in some embodiments, the movable component includes a first movable assembly 101, which is slidably connected to a fixed component along a first direction; the electric drive component includes a first electric drive component 102, the output end of which is connected to the first movable assembly 101, and the fixed end of which is connected to the fixed component or used to connect to the vehicle body, for driving the first movable assembly 101 to reciprocate along the first direction.

[0091] In other words, this embodiment uses a first movable component 101, driven by a first electric drive component 102, to reciprocate along a first direction. This first direction can be any direction in a Cartesian coordinate system; for example, it can be a horizontal, vertical, or other orientation. It should be noted that the horizontal direction refers to the extension and retraction of the first movable component 101 relative to the side of the vehicle body, used to move closer to or further away from the track beam and third rail; the vertical direction refers to the lifting direction of the maintenance platform, used to adapt to different work positions; and the horizontal direction refers to the forward and backward movement of the maintenance platform along the length of the vehicle body, used to adjust the work position. This solution enables single-degree-of-freedom movement of the maintenance platform's worktable along the first direction, simplifying the complexity of the mechanism and improving the reliability of the movement. It is understood that the maintenance platform's worktable is directly or indirectly located on the first movable component 101, and the purpose of the movable component's movement is to change the position of the worktable.

[0092] It should be noted that this embodiment does not limit the specific implementation of the first electric drive component 102. For example, the first electric drive component 102 can be an electric actuator, an electric cylinder, a motor lead screw mechanism, a motor gear rack mechanism, a linear motor, or a linear module, etc. For example, the first electric drive component 102 is an electric actuator, one end of which is connected to the first movable component 101 (for example, connected to the first end frame 1011 mentioned below), and the other end of which is used to connect to the vehicle body.

[0093] Furthermore, such as Figure 8 and Figure 9 As shown, in order to improve the reliability of the reciprocating motion of the first movable component 101 along the first direction, in some embodiments, the fixing member includes two parallel third guide rails 103, which are used to connect with the vehicle body; the first movable component 101 is slidably connected to the two third guide rails 103 through two third sliders 1031.

[0094] In other words, in this embodiment, the fixing components are two third guide rails 103, which are connected to the vehicle body. For example, the connection between the third guide rails 103 and the vehicle body is achieved by fasteners. It can be understood that the extension direction of the third guide rails 103 is a first direction, for example, a horizontal direction, so as to limit the movement direction of the first movable component 101 by using the first guide rails. The two third sliders 1031 are slidably connected to the two third guide rails 103 in a one-to-one correspondence. The first movable component 101 is connected to the two third sliders 1031, for example, by fasteners. In other words, in this embodiment, the movement of the first movable component 101 relative to the fixed component along the first direction is limited by the cooperation of the third slider 1031 and the third guide rail 103. The application of the third guide rail 103 provides rigid support and precise guidance for the reciprocating movement of the first movable component 101 along the first direction, ensuring the stability and structural rigidity of the first movable component 101 during movement, load-bearing and operation along the first direction, effectively reducing swaying, and improving operational safety and user experience. Moreover, the two third guide rails 103 form a double guide rail combination structure, which together constrains the movement direction of the first movable component 101, forming a stable movement plane, and improving the overturning resistance of the maintenance platform at the extreme extension position.

[0095] In addition, it should be noted that the above embodiments do not limit the specific structure of the first movable component 101, as long as the first movable component 101 can be directly or indirectly connected to the worktable so that the movement of the first movable component 101 can drive the worktable to reciprocate along the first direction.

[0096] like Figure 7 and Figure 8 As shown, in some embodiments, the first movable component 101 includes two opposing first end frames 1011 and at least one longitudinal beam. The two first end frames 1011 are respectively connected to two third sliders 1031. The longitudinal beam is connected between one side edge of the two first end frames 1011. For example, there are two longitudinal beams, namely an upper longitudinal beam 1012 and a lower longitudinal beam 1013, and a decorative panel 1014 can be provided between the upper longitudinal beam 1012 and the lower longitudinal beam 1013.

[0097] It is understood that in this embodiment, the two first end frames 1011 are connected together by at least one longitudinal beam to form an integral structure, which improves the stability of the first movable component 101 structure and facilitates the overall movement of the first movable component 101 in the first direction. Furthermore, the longitudinal beam connects the two first end frames 1011 to one side edge, that is, the two first end frames 1011 and the longitudinal beam form a C-shaped structure, creating an accommodating space between the two first end frames 1011 for operators to enter and perform maintenance work. Exemplarily, the first end frame 1011 is a frame structure, which reduces weight while ensuring the structural strength of the first end frame 1011.

[0098] In addition, such as Figure 1 As shown, in some embodiments, the movable component further includes a second movable component 104, which is slidably connected to the first movable component 101 along a second direction, the second direction having an angle with the first direction; the electric drive component further includes a second electric drive component 105, which is connected between the first movable component 101 and the second movable component 104, for driving the second movable component 104 to reciprocate along the second direction.

[0099] In other words, this embodiment, by setting a second movable component 104, uses a second electric drive component 105 to drive the second movable component 104 to reciprocate along a second direction. The second direction has an angle with the first direction, forming a movement direction different from the first direction. This solution introduces a second movement dimension based on the movement of the first movable component 101 along the first direction, forming a two-degree-of-freedom serial motion structure to achieve multi-dimensional movement of the worktable. It can be understood that the second movable component 104 is a component in the maintenance platform responsible for performing movement in another different direction. It is not directly connected to the fixed component, but is installed on the first movable component 101. While moving along the first direction with the first movable component 101, it can also independently move relative to the first movable component 101 along the second direction. For example, the first direction is horizontal, and the second direction is vertical. That is, the first movable component 101 and the second movable component 104 move together horizontally, and the second movable component 104 can move up and down vertically. The movement of the first active component 101 along the first direction and the movement of the second active component 104 along the second direction can be performed simultaneously or sequentially, without interfering with each other.

[0100] The second electric drive element 105 is an electric actuator specifically designed to power the second movable component 104. When the second electric drive element 105 actuates, it directly drives the second movable component 104 to move relative to the first movable component 101 along the second direction. This embodiment does not limit the specific implementation of the second electric drive element 105, as long as it can drive the second movable component 104 to move along the second direction. For example, the second electric drive element 105 is an electric lift.

[0101] In addition, this embodiment does not limit the specific structure of the second movable component 104, as long as the second movable component 104 can move relative to the first movable component 101 in the second direction.

[0102] like Figure 10 As shown, in some embodiments, the second active component 104 includes two opposing second end frames 1041 and a base plate 1042 connected between the bottoms of the two second end frames 1041, with the two second end frames 1041 slidably connected to the two first end frames 1011 in a one-to-one correspondence.

[0103] In other words, in this embodiment, the second end frame 1041 serves as a sliding and moving support; the base plate 1042 provides a workbench position for supporting operators or equipment. The two second end frames 1041 are connected together via the base plate 1042 to form an integral second movable component 104, providing a stable working platform while balancing structural strength and lightweight design, exhibiting good overall rigidity and minimal deformation under load. Simultaneously, the two second end frames 1041 are slidably connected one-to-one with the two first end frames 1011 of the first movable component 101, thus realizing the second movable component 104. 04 Relative to the movement of the first movable component 101 along the second direction, the two second end frames 1041 and the two first end frames 1011 are connected by corresponding sliding connections to form an overall left-right symmetrical sliding structure, which makes the movement of the second movable component 104 along the second direction smooth and avoids tilting of the second movable component 104 during the movement along the second direction. In addition, sufficient accommodating space is formed between the two first end frames 1011 and the two second end frames 1041 for operators to enter or place tools, etc., making the overall structure compact and the maintenance space large.

[0104] Furthermore, such as Figure 10 and Figure 11 As shown, in some embodiments, one of the second end frame 1041 and the corresponding first end frame 1011 is provided with a fourth guide rail 1043, and the other is provided with a fourth slider that is slidably connected to the fourth guide rail 1043.

[0105] In other words, this embodiment ensures the smooth movement of the second movable component 104 relative to the first movable component 101 by setting a fourth guide rail 1043 and a fourth slider structure between the first end frame 1011 and the corresponding second end frame 1041, avoiding jamming and improving reliability. Furthermore, the cooperation between the fourth slider and the fourth guide rail 1043 facilitates repeated positioning and precise operation. For example, fourth guide rails 1043 extending along the second direction are respectively set on both sides of each first frame along the first direction. That is, the second end frame 1041 and the corresponding first end frame 1011 are connected by a guide structure formed by the combination of two sets of fourth guide rails 1043 and fourth sliders, ensuring the smoothness and reliability of the sliding of the second end frame 1041 relative to the first end frame 1011.

[0106] In some embodiments, there are two second electric drive units 105, which are correspondingly arranged with two second end frames 1041. One second electric drive unit 105 is close to one second end frame 1041. For example, each second electric drive unit 105 includes a motor, a lead screw connected to the motor, and a sliding nut threadedly connected to the lead screw. The lead screw is arranged in a vertical direction parallel to the second end frame 1041 and the first end frame 1011. The top end of the lead screw is rotatably connected to the first end frame 1011, and the bottom end of the lead screw is rotatably connected to the base plate 1042.

[0107] In addition, such as Figure 1 , Figure 12 , Figure 14 , Figure 16 and Figure 17 As shown, in some embodiments, the movable component further includes at least one of a first flap assembly 106 and a second flap assembly 107, wherein the first flap assembly 106 is hinged to a first side of the base plate 1042, and the second flap assembly 107 is hinged to a second side of the base plate 1042; the electric drive component further includes at least one of a third electric drive component 108 and a fourth electric drive component 109, wherein the third electric drive component 108 is connected between the second end frame 1041 and the first flap assembly 106, and the fourth electric drive component 109 is connected between the second end frame 1041 and the second flap assembly 107.

[0108] In other words, this embodiment further provides a flip-plate assembly based on the first movable component 101 and the second movable component 104. The flip-plate assembly can be provided only on one side of the base plate 1042, or it can be provided on both sides of the base plate 1042. For example, a first flip-plate assembly 106 can be provided on the first side of the base plate 1042, or a second flip-plate assembly 107 can be provided on the second side of the base plate 1042, or the first flip-plate assembly 106 can be provided on the first side of the base plate 1042 and the second flip-plate assembly 107 can be provided on the second side of the base plate 1042. It can be understood that the first side and the second side of the base plate 1042 refer to the opposite sides of the base plate 1042 located between the two second end frames 1041. The first flap assembly 106 and the second flap assembly 107 are respectively hinged to the base plate 1042 to flip relative to the base plate 1042. The first flap assembly 106 and the second flap assembly 107 can flip upward or downward relative to the base plate 1042 to increase the area of ​​the base plate 1042 when unfolded, thereby increasing the working area, and to reduce the space occupied when folded, or to serve as a safety railing to provide protection for the operator. For example, the first flap assembly 106 is connected to the base plate 1042 via a first hinge 1062, and the second flap assembly 107 is connected to the base plate 1042 via a second hinge 1075.

[0109] In this embodiment, the first flip plate assembly 106 is driven to rotate and flip relative to the base plate 1042 by the third electric drive unit 108, and the second flip plate assembly 107 is driven to rotate and flip relative to the base plate 1042 by the fourth electric drive unit 109, so as to realize the automatic flipping of the first flip plate assembly 106 and the second flip plate assembly 107, without the need for manual bending or forceful lifting, thus reducing labor intensity.

[0110] It should be noted that this embodiment does not limit the specific implementation of the third electric drive component 108 and the fourth electric drive component 109, as long as the third electric drive component 108 can cause the first flip plate assembly 106 to flip relative to the base plate 1042, and the fourth electric drive component 109 can cause the second flip plate assembly 107 to flip relative to the base plate 1042. For example, both the third electric drive component 108 and the fourth electric drive component 109 are electric actuators.

[0111] Furthermore, such as Figure 10 As shown, in some embodiments, the second end frame 1041 is connected to a mounting portion 1044, the mounting portion 1044 is connected to the output end of the second electric drive member 105, the fixed ends of the third electric drive member 108 and the fourth electric drive member 109 are respectively connected to the mounting portion 1044, and the third electric drive member 108 and the fourth electric drive member 109 connected to the same second end frame 1041 are arranged in a cross configuration.

[0112] For example, each of the two second end brackets 1041 is provided with a mounting portion 1044. The number of the second electric drive unit 105, the third electric drive unit 108 and the fourth electric drive unit 109 are all two. The output end of one second electric drive unit 105, the fixed end of one third electric drive unit 108 and the fixed end of one fourth electric drive unit 109 are integrated and connected to one mounting portion 1044.

[0113] In other words, this embodiment uses a mounting section 1044 as a common support point for multiple electric drive components. The output end of the second electric drive component 105, the fixed end of the third electric drive component 108, and the fixed end of the fourth electric drive component 109 are integrated into the mounting section 1044. This section transmits the power output by the second electric drive component 105 for movement in the second direction and provides mounting points for the third and fourth electric drive components 108 and 109, enabling them to move as a whole in the second direction. Furthermore, it bears the force exerted by the third and fourth electric drive components 108 and 109 when they move. This design results in a compact installation structure, a neat appearance, and facilitates centralized routing of cables 113 and conduits, leading to a more aesthetically pleasing and easier-to-maintain overall appearance. Additionally, it is understood that the mounting section 1044 can be designed as a universal module applicable to both second end brackets 1041, reducing the number of parts and facilitating standardized production. Additionally, it should be noted that the mounting part 1044 can be a welded bracket with multiple lugs, or a cast-in-place bracket.

[0114] Additionally, it is understood that the third electric drive unit 108 and the fourth electric drive unit 109 connected to the same second end frame 1041 are arranged in a cross configuration. This means that the third electric drive unit 108 and the fourth electric drive unit 109 connected to the same second end frame 1041 form a staggered cross, that is, a projected cross in the side view direction, to avoid mutual collision and contact between the third electric drive unit 108 and the fourth electric drive unit 109 connected to the same second end frame 1041. For example, the connection point between the third electric drive unit 108 and the mounting part 1044 is... On the side of the mounting portion 1044 near the second flap assembly 107, the connection point between the fourth electric drive unit 109 and the mounting portion 1044 is located on the side of the mounting portion 1044 near the first flap assembly 106. The connection points between the third electric drive unit 108 and the mounting portion 1044 and the fourth electric drive unit 109 and the mounting portion 1044 are staggered in the direction between the two second end frames 1041. In this way, the third electric drive unit 108 and the fourth electric drive unit 109 on the same side are arranged crosswise and do not contact or interfere with each other. This design can accommodate the third electric drive unit 108 and the fourth electric drive unit 109 simultaneously without increasing the width of the second end frame 1041. These drive the first flap assembly 106 and the second flap assembly 107 respectively, which helps to save space and maximize space utilization. Furthermore, the cross arrangement of the third electric drive unit 108 and the fourth electric drive unit 109 on the same side allows the forces exerted by the third electric drive unit 108 and the fourth electric drive unit 109 on the second end frame 1041 to cancel each other out or balance each other, reducing additional bending moments, optimizing mechanical distribution, and improving the coordination of multiple drive units.

[0115] In addition, such as Figure 13 and Figure 15 As shown, in order to limit the maximum flip angle of the first flip assembly 106 relative to the base plate 1042, and / or to limit the maximum flip angle of the second flip assembly 107 relative to the base plate 1042, in some embodiments, a first rotating arm assembly 1061 is hinged between the first flip assembly 106 and the base plate 1042, the first rotating arm assembly 1061 being used to limit the maximum rotation angle of the first flip assembly 106 when it is unfolded; and / or, a second rotating arm assembly 1071 is hinged between the second flip assembly 107 and the base plate 1042, the second rotating arm assembly 1071 being used to limit the maximum rotation angle of the second flip assembly 107 when it is unfolded.

[0116] In other words, this embodiment uses a first rotating arm assembly 1061 between the first flip plate assembly 106 and the base plate 1042 to limit the maximum flip angle of the first flip plate assembly 106 relative to the base plate 1042. For example, the first rotating arm assembly 1061 includes a first rotating arm and a second rotating arm hinged together. The first rotating arm is hinged to the first flip plate assembly 106, and the second rotating arm is hinged to the base plate 1042. When the third electric drive unit 108 drives the first flip plate assembly 106 to flip and unfold relative to the base plate 1042, the first flip plate assembly 106 drives the first rotating arm and the second rotating arm to rotate relative to each other until the first and second rotating arms are fully extended. Under the mechanical limitation of the first and second rotating arms, the first flip plate assembly 106 remains at the position of the maximum flip angle. That is, when the first flip plate assembly 106 reaches the maximum flip angle, it cannot continue to rotate, thus preventing the first flip plate assembly 106 from over-flipping. When the third electric drive unit 108 drives the first flap assembly 106 to flip and retract relative to the base plate 1042, the first rotating arm and the second rotating arm rotate relative to each other and retract, thus avoiding affecting the retraction of the first flap assembly 106. In some embodiments, when the first flap assembly 106 flips and unfolds, the first flap assembly 106 is coplanar with the base plate 1042 to expand the area of ​​the base plate 1042; when the first flap assembly 106 flips and retracts, the first flap assembly 106 is perpendicular to the base plate 1042.

[0117] Similarly, in this embodiment, a second rotating arm assembly 1071 is provided between the second flip plate assembly 107 and the base plate 1042. The second rotating arm assembly 1071 limits the maximum flip angle of the second flip plate assembly 107 relative to the base plate 1042. For example, the second rotating arm assembly 1071 includes a third rotating arm and a fourth rotating arm that are hinged together. The third rotating arm is hinged to the second flip plate assembly 107, and the fourth rotating arm is hinged to the base plate 1042. When the fourth electric drive unit 109 drives the second flip plate assembly 107 to flip and unfold relative to the base plate 1042, the second flip plate assembly 107 drives the third and fourth rotating arms to rotate relative to each other until the third and fourth rotating arms are fully extended. Under the mechanical limit of the third and fourth rotating arms, the second flip plate assembly 107 is stopped at the position of the maximum flip angle. That is, when the second flip plate assembly 107 reaches the maximum flip angle, it will be unable to continue rotating, thus avoiding over-flipping of the second flip plate assembly 107. When the fourth electric drive unit 109 drives the second flap assembly 107 to flip and retract relative to the base plate 1042, the third and fourth rotating arms rotate relative to each other and retract, thus avoiding affecting the retraction of the second flap assembly 107. In some embodiments, when the second flap assembly 107 flips and unfolds, the second flap assembly 107 is coplanar with the base plate 1042 to expand the area of ​​the base plate 1042; when the second flap assembly 107 flips and retracts, the second flap assembly 107 is perpendicular to the base plate 1042.

[0118] Furthermore, such as Figure 15 As shown, in some embodiments, the second flap assembly 107 includes a first flap 1072 hinged to the base plate 1042 and a second flap 1073 hinged to the side of the first flap 1072 away from the base plate 1042. A fourth electric drive unit is hinged to the second flap 1073. A detachable locking member 1074 is provided between the first flap 1072 and the second flap 1073. When the locking member 1074 is removed, the first flap 1072 and the second flap 1073 can be flipped relative to each other. When the locking member 1074 connects the first flap 1072 and the second flap 1073, the first flap 1072 and the second flap 1073 are fixed relative to each other.

[0119] In other words, in this embodiment, the second flap assembly 107 includes a first flap 1072 and a second flap 1073 that are hinged together in sequence. The first flap 1072 is hinged to the base plate 1042, meaning that the first flap 1072 and the second flap 1073 can be flipped relative to the base plate 1042 as a whole, and the second flap 1073 can be flipped relative to the first flap 1072. Therefore, by simultaneously flipping and unfolding both the first flap 1072 and the second flap 1073, the first flap 1072, the second flap 1073, and the base plate 1042 can be made coplanar, thus expanding the area of ​​the base plate 1042. Alternatively, by flipping and unfolding the first flap 1072, and making the second flap 1073 perpendicular to the first flap 1072, the first flap 1072 can expand the area of ​​the base plate 1042 while the second flap 1073 serves as a fence to improve safety. In addition, to ensure the reliability of the relative position of the first flap 1072 and the second flap 1073, this embodiment provides a locking member 1074 between the first flap 1072 and the second flap 1073. When the locking member 1074 is installed, it connects the first flap 1072 and the second flap 1073 together, for example, making the first flap 1072 and the second flap 1073 coplanar or perpendicular. When the locking member 1074 is removed, the first flap 1072 and the second flap 1073 can rotate relative to each other. Exemplarily, the locking member 1074 includes a pin and sockets respectively provided on the first flap 1072 and the second flap 1073. By inserting the pin, the locking member 1074 connects the first flap 1072 and the second flap 1073 together. By pulling out the pin, the connection between the first flap 1072 and the second flap 1073 is released, allowing the first flap 1072 and the second flap 1073 to rotate relative to each other.

[0120] like Figure 12As shown, in some embodiments, the straddle-type monorail work vehicle maintenance platform further includes an electronic control device 110 and an operating platform 111. Both the electronic control device 110 and the operating platform 111 are located on fixed or movable parts. The operating platform 111 is connected to the electronic control device 110, and the electronic control device 110 is connected to each electric drive component. For example, the electronic control device 110 is connected to the first electric drive component 102, the second electric drive component 105, the third electric drive component 108, and the fourth electric drive component 109, respectively, to control the first electric drive component 102, the second electric drive component 105, the third electric drive component 108, and the fourth electric drive component 109 to move independently, or to control at least two of the first electric drive component 102, the second electric drive component 105, the third electric drive component 108, and the fourth electric drive component 109 to move synchronously.

[0121] In other words, the electronic control device 110 and the control panel 111 in this embodiment form an electronic control system to control the operation of each electric drive component. It can be understood that the control panel 111 is operated by the operator to input operating commands to the electronic control device 110. The electronic control device 110 receives the control commands from the control panel 111, processes them according to preset logic, and then outputs corresponding drive signals (such as forward / reverse rotation, start / stop, speed adjustment, etc.) to each electric drive component to achieve the action of each electric drive component. This solution combines the control panel 111 and the electronic control device 110 to form a centralized, electrically powered, and intelligently controllable electronic control system, improving operating efficiency, reducing operating difficulty, enhancing safety, facilitating maintenance, and laying a control foundation for subsequent automation and intelligent upgrades.

[0122] It should be noted that the control panel 111 can be a control panel with buttons, knobs or a touch screen.

[0123] Furthermore, the electronic control device 110 can control the first electric drive component 102, the second electric drive component 105, the third electric drive component 108, and the fourth electric drive component 109 to move independently. This ensures that the movements of the first movable component 101, the second movable component 104, the first flapping component 106, and the second flapping component 107 are independent and do not interfere with each other. This results in simple control logic, high system reliability, and facilitates precise fine-tuning and positioning. The electronic control device 110 can also control at least two of the first electric drive component 102, the second electric drive component 105, the third electric drive component 108, and the fourth electric drive component 109 to move synchronously. That is, it enables at least two of the first movable component 101, the second movable component 104, the first flapping component 106, and the second flapping component 107 to form a composite movement. This facilitates the movement of the maintenance platform along diagonal or arc trajectories to smoothly bypass obstacles, improves positioning accuracy, reduces repeated adjustments, and significantly increases work efficiency while shortening adjustment time.

[0124] In other embodiments, the electronic control device 110 has two control modes: an independent motion mode (that is, the electronic control device 110 controls the first electric drive 102, the second electric drive 105, the third electric drive 108, and the fourth electric drive 109 to move independently) and a composite motion mode (that is, the electronic control device 110 controls at least two of the first electric drive 102, the second electric drive 105, the third electric drive 108, and the fourth electric drive 109 to move synchronously). The switching between the two control modes is achieved by operating the control panel 111.

[0125] In addition, to facilitate operators' access to and from the workbench, such as Figure 1 As shown, in some embodiments, the straddle-type monorail work vehicle maintenance platform further includes a stair assembly 112, which is connected to the first movable assembly 101. Exemplarily, one end of the stair assembly 112 is connected to the upper longitudinal beam 1012 of the first movable assembly 101, and the other end is connected to the base plate 1042 of the second movable assembly 104.

[0126] It is understandable that the aforementioned electric drive components are connected to cables 113 (such as...). Figure 12 As shown), electrical energy is supplied to the electric drive components via cable 113 to realize the operation of each electric drive component.

[0127] In addition to the aforementioned straddle-type monorail maintenance platform, this embodiment of the invention also provides a straddle-type monorail maintenance vehicle. This vehicle includes the straddle-type monorail maintenance platform disclosed in the above embodiments and a vehicle body. The straddle-type monorail maintenance platform is installed on the vehicle body. For example, the straddle-type monorail maintenance platform is connected to the bottom 1 of the vehicle body via a fixed bracket 2, or the straddle-type monorail maintenance platform is connected to the vehicle body via a fastener, exemplarily, via a third guide rail 103. For the structure of other parts of the straddle-type monorail maintenance vehicle and the specific structure of the vehicle body, please refer to relevant technologies; these will not be elaborated upon here.

[0128] The key point of this embodiment is that the straddle-type monorail work vehicle includes the aforementioned straddle-type monorail work vehicle maintenance platform, and at least has the beneficial effects of the aforementioned straddle-type monorail work vehicle maintenance platform, which will not be elaborated here.
