Description

Technical Field

[0001] This invention relates to the field of electrified highway technology, and more particularly to an electrified highway transport system vehicle, control method, equipment, and storage medium. Background Technology

[0002] Electrified road transport vehicles are road vehicles powered by a DC overhead contact line, driven by electricity, and equipped with additional onboard energy storage devices. Power exchange between the vehicle and the DC contact line is achieved through a return current method. Electrified road transport vehicles typically use a pantograph system consisting of two sets of pantograph assemblies to collect power from the DC contact line while the vehicle is stationary or in motion. The input DC voltage is stepped down using an interleaved three-level algorithm via a DC-DC converter cabinet, and the output voltage powers the traction inverter and battery.

[0003] During the initial construction of electrified highways, the height of the overhead contact line could not be kept consistent across different road sections when upgrading existing roads. This resulted in varying requirements for the pantograph-catenary line boundary when vehicles in electrified highway transport systems traveled to different areas, necessitating recalculation of the pantograph-catenary height and readjustment of the contact pressure. When troubleshooting or repairing vehicles in electrified highway transport systems, it is generally necessary to tilt the cab to inspect the vehicle's main control unit while the pantograph is in the lowered position. However, because the pantograph arm is directly above the cab at this time, the cab's maneuverability is limited.

[0004] Therefore, there is a lack of existing technologies that can simultaneously meet the pantograph-catenary limit requirements of vehicles in electrified highway transport systems and the vehicle maintenance requirements. Summary of the Invention

[0005] The purpose of this invention is to provide an electrified road transport system vehicle, control method, equipment, and storage medium that can simultaneously meet the pantograph-catenary limit requirements and vehicle maintenance requirements of the electrified road transport system vehicle.

When the pantograph is at the first preset height, the lowest pantograph arm height at the lowering position is greater than the maximum maintenance tilting height of the cab; When the pantograph is at the second preset height, the pantograph-catenary contact pressure generated when the pantograph is raised satisfies the pantograph-catenary operation relationship.

[0007] Furthermore, the pantograph includes a conductive component and an insulating component; the fixed end of the pantograph is detachably connected to the flange platform through the insulating component; when the pantograph is raised, it forms a closed circuit by electrically connecting to the power supply contact network and the DC-DC converter module in the converter cabinet through the conductive component.

The lifting controller is connected in communication with the motor and is used to control the motor to make the telescopic support frame and the scissor lift structure lift synchronously.

[0010] Furthermore, the scissor lift structure includes multiple scissor arm assemblies connected in sequence, each scissor arm assembly including two scissor arms arranged in a cross pattern and connected by a hinge shaft; the first slide groove is provided with two first sliders, and the two scissor arms in the bottom scissor arm assembly are respectively hinged to the two first sliders; the second slide groove is provided with two second sliders, and the two scissor arms in the top scissor arm assembly are respectively hinged to the two second sliders.

[0011] Furthermore, the lifting assembly also includes a limit switch, which is disposed on the flange platform and communicates with the lifting controller, for locking when the lifting controller controls the telescopic support frame and the scissor lift structure to rise to the maximum height.

[0012] Secondly, a control method for vehicles in an electrified highway transportation system is provided, including: When the pantograph of a vehicle in an electrified highway transport system is in the lowered position, in response to the pantograph raising... The high command controls the pantograph to move to a first preset height or a second preset height; When the pantograph is at the first preset height, in response to a maintenance command, the cab is controlled to tilt, wherein the lowest pantograph arm height in the pantograph lowering position is greater than the maximum maintenance tilting height of the cab; When the pantograph is at the second preset height, in response to the pantograph raising command, the pantograph is controlled to be raised, and the pantograph-catenary contact pressure generated during the raising satisfies the pantograph-catenary operation relationship.

[0013] Furthermore, the lifting assembly for controlling the raising and lowering of the pantograph includes: A base is installed in the cabinet of the converter cabinet, and a first sliding groove is provided on the base; A telescopic support frame, the bottom of which is connected to the base and the top of which is connected to the flange platform; The scissor lift structure has its bottom end slidably connected to the first slide groove and its top end slidably connected to the second slide groove on the flange platform. The lifting controller is connected to the motor and is used to control the motor to drive the telescopic support frame and the scissor lift structure to lift synchronously.

[0020] 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.

[0021] like Figure 1 and Figure 2 As shown, the first embodiment of the present invention provides an electrified highway transportation system vehicle, including: a vehicle chassis 1, a cab 2 rotatably mounted on the vehicle chassis 1, a converter cabinet 3 mounted on the vehicle chassis 1 and located behind the cab 2, a lifting platform 4 installed in the cabinet of the converter cabinet 3 and driven by a motor to lift and lower at the open end of the converter cabinet 3, and a pantograph 5 mounted on the top of the lifting platform 4.

[0022] The lifting platform 4 includes a lifting assembly and a flange platform 7. The fixed end of the pantograph 5 is installed on the flange platform 7. The lifting assembly is used to control the pantograph 5 in the lowering position to move to a first preset height or a second preset height.

[0023] According to an embodiment of the present invention, when the pantograph 5 is at the first preset height, the lowest pantograph arm height of the pantograph 5 in the lowering position is greater than the maximum maintenance tilting height of the cab 2; when the pantograph 5 is at the second preset height, the pantograph-catenary contact pressure generated when the pantograph 5 is raised satisfies the pantograph-catenary operation relationship. Figure 2 As shown, the cab maintenance tilt radius can be understood as the forward tilt radius of the cab with a certain point on the chassis 1 as the fulcrum. The maximum maintenance tilt height of the cab is the height of the highest point of the cab from the ground during the tilting process. The minimum pantograph arm height of the pantograph 5 is the minimum height of the pantograph arm 6 from the ground.

[0024] In the electrified highway transport system vehicle provided in this embodiment of the invention, during vehicle maintenance, the lifting platform 4 is raised and lowered by a motor, and the height of the pantograph 5 installed on the top of the lifting platform 4 in the lowered position is adjusted so that the lowest pantograph arm height of the pantograph 5 in the lowered position is greater than the maximum maintenance tilting height of the cab 2. When the cab 2 tilts, it will not collide with the pantograph arm 6, so the vehicle can be inspected and maintained without raising the pantograph, which is highly operable. The lowered position height of the pantograph 5 can also be adjusted according to different pantograph-catenary boundary heights so that the pantograph-catenary contact pressure generated when the pantograph 5 is raised meets the pantograph-catenary operation relationship, thereby ensuring reliable contact with the power supply contact network when the pantograph is raised and generating good pantograph-catenary contact pressure, thus solving the compatibility problem of the pantograph under different pantograph-catenary boundaries.

[0025] According to a preferred embodiment, the pantograph 5 includes a conductive component and an insulating component. The fixed end of the pantograph 5 is detachably connected to the flange platform 7 via the insulating component. When the pantograph 5 is raised, it forms a closed circuit by electrically connecting to the power supply contact network and the DC-DC converter module in the converter cabinet 3 via the conductive component.

[0026] like Figure 2 As shown, the fixed end of the pantograph 5 includes a mounting plate 8. The insulation assembly includes a plurality of insulators 9, each insulator 9 having a radial mounting hole. Fastening bolts pass sequentially through the mounting plate 8 of the pantograph 5, the mounting holes of the insulators 9, and the flange platform 7 to fix the pantograph 5 to the lifting platform 4. Exemplarily, four M16 bolts are used to fix the mounting interfaces of the four insulators of the pantograph to the flange platform of the lifting platform.

[0027] like Figure 2As shown, the lifting components for controlling the lifting platform 4 include: a base (not shown in the figure), a telescopic support frame 40, a scissor-type lifting structure 41, a lifting controller 42, and a motor.

[0028] According to a preferred embodiment, the base is installed in the cabinet of the converter cabinet. The base has a first sliding groove, and the flange platform 7 has a second sliding groove on its opposite side. The bottom end of the telescopic support frame 40 is connected to the base, and its top end is connected to the flange platform 7. The bottom end of the scissor lift structure 41 is slidably connected to the first sliding groove, and its top end is slidably connected to the second sliding groove on the flange platform 7. The lifting controller 42 is communicatively connected to the motor and is used to control the motor to drive the telescopic support frame 40 and the scissor lift structure 41 to lift synchronously. Preferably, the telescopic support frame 40 is driven to lift using a first motor, and the scissor lift structure 41 is driven to lift using a second motor.

[0029] The scissor lift structure 41 includes multiple scissor arm assemblies connected in sequence. Each scissor arm assembly includes two scissor arms arranged in a cross pattern and connected by a hinge shaft. The first slide groove contains two first sliders, and the two scissor arms in the bottom scissor arm assembly are hinged to the two first sliders respectively. The second slide groove contains two second sliders, and the two scissor arms in the top scissor arm assembly are hinged to the two second sliders respectively.

[0030] The scissor lift structure 41 is raised by controlling the lateral retraction of the scissor arm assembly, and lowered by controlling the lateral extension of the scissor arm assembly. Specifically, when the scissor lift structure 41 rises, the two first sliders slide relative to each other along the first slide groove, and the two second sliders slide synchronously relative to each other within the second slide groove; when the scissor lift structure 41 lowers, the two first sliders slide towards each other along the first slide groove, and the two second sliders slide towards each other synchronously within the second slide groove.

[0031] According to an embodiment of the present invention, the working principle of the lifting platform 4 is as follows: the lifting controller 42 controls the first motor and the second motor to rotate synchronously in the forward direction, and the scissor arm assembly retracts laterally (i.e., along the direction of the first slide groove and the direction of the second slide groove, the directions are the same), causing the top of the scissor lifting structure 41 to gradually rise, and the telescopic support frame 40 extends longitudinally, causing the scissor lifting structure 41 and the telescopic support frame 40 to rise synchronously; the lifting controller 42 controls the first motor and the second motor to rotate synchronously in the reverse direction, and the scissor arm assembly extends laterally, causing the top of the scissor lifting structure 41 to fall, and the telescopic support frame 40 retracts longitudinally, causing the scissor lifting structure 41 and the telescopic support frame 40 to fall synchronously; when the scissor lifting structure 41 and the telescopic support frame 40 move to a preset height, the motor stops, and the telescopic support frame 40 supports the flange platform 7, providing sufficient support force for the pantograph 5.

[0032] Preferably, the lifting assembly further includes a limit switch 10.

[0033] The limit switch 10 is mounted on the flange platform 7 and is communicatively connected to the lifting controller 42. It is used to lock the telescopic support frame 40 and the scissor lift structure 41 when the lifting controller 42 controls them to rise to the maximum height.

[0034] like Figure 3 As shown, the second embodiment of the present invention also provides a control method for vehicles in an electrified road transport system, applied to the electrified road transport system vehicles provided in the first embodiment above. The method includes the following steps: S1. When the pantograph of an electrified road transport system vehicle is in the lowered position, in response to the power supply... The command to raise the pantograph controls the pantograph to move to a first preset height or a second preset height. S2. When the pantograph is at the first preset height, in response to the maintenance command, the cab is controlled to tilt, wherein the lowest pantograph arm height at the lowered position is greater than the maximum maintenance tilting height of the cab. S3. When the pantograph is at the second preset height, in response to the pantograph raising command, the pantograph is controlled to be raised, and the pantograph-catenary contact pressure generated during the raising satisfies the pantograph-catenary operation relationship.

[0035] When the cab tilts forward using a point on the chassis as a fulcrum, the maximum maintenance tilting height of the cab is the height of the highest point of the cab from the ground during the tilting process. According to an embodiment of the present invention, by adjusting the height of the pantograph at the lowering position, when the pantograph is adjusted to the first preset height, the lowest pantograph arm height at the lowering position, that is, the lowest height of the pantograph arm from the ground, is greater than the maximum maintenance tilting height of the cab, providing sufficient space for the cab to tilt for maintenance. This allows for vehicle inspection and maintenance without raising the pantograph, making it highly operable. When the pantograph is at the second preset height, the pantograph-catenary contact pressure generated when the pantograph is raised satisfies the pantograph-catenary operation relationship, ensuring reliable contact between the pantograph and the power supply contact network, thereby solving the compatibility problem of the vehicle under different pantograph-catenary boundaries.

[0036] In an electrified highway transport system vehicle, the cab is rotatably mounted on the chassis, the converter cabinet is mounted on the chassis and located behind the cab, the lifting platform is mounted in the cabinet of the converter cabinet and is driven by a motor to lift and lower at the open end of the converter cabinet, and the pantograph is mounted on the top of the lifting platform.

[0037] The lifting platform includes a lifting assembly and a flange platform, with the fixed end of the pantograph mounted on the flange platform. According to a preferred embodiment, the lifting assembly controlling the pantograph's lifting includes: a base, a telescopic support frame, a scissor-type lifting structure, a lifting controller, and a motor.

[0038] The base is installed inside the converter cabinet. A first sliding groove is provided on the base, and a second sliding groove is provided on the flange platform opposite to the base. The bottom end of the telescopic support frame is connected to the base, and its top end is connected to the flange platform. The bottom end of the scissor lift structure is slidably connected to the first sliding groove, and its top end is slidably connected to the second sliding groove on the flange platform. The lifting controller is communicatively connected to the motor and is used to control the motor to drive the telescopic support frame and the scissor lift structure to move synchronously. Preferably, a first motor drives the telescopic support frame to move, and a second motor drives the scissor lift structure to move.

[0039] Preferably, the telescopic support frame is driven to rise and fall by a first motor, and the scissor lift structure is driven to rise and fall by a second motor.

[0040] According to one specific embodiment, the scissor lift structure includes multiple scissor arm assemblies connected in sequence. Each scissor arm assembly includes two scissor arms arranged in a cross configuration and connected by a hinge shaft. Two first sliders are provided inside the first slide groove, and the two scissor arms in the bottom scissor arm assembly are respectively hinged to the two first sliders. Two second sliders are provided inside the second slide groove, and the two scissor arms in the top scissor arm assembly are respectively hinged to the two second sliders.

[0041] The scissor lift structure rises by controlling the lateral retraction of the scissor arm assembly, and descends by controlling the lateral extension of the scissor arm assembly. Specifically, when the scissor lift structure rises, the two first sliders slide relative to each other along the first slide groove, and the two second sliders slide synchronously relative to each other within the second slide groove; when the scissor lift structure descends, the two first sliders slide towards each other along the first slide groove, and the two second sliders slide towards each other synchronously within the second slide groove.

[0042] According to an embodiment of the present invention, the working principle of the lifting platform is as follows: the lifting controller controls the first motor and the second motor to rotate synchronously in the forward direction, and the scissor arm assembly retracts laterally (i.e., along the direction of the first slide groove and the direction of the second slide groove, the directions are the same), causing the top of the scissor-type lifting structure to gradually rise, and the telescopic support frame extends longitudinally, causing the scissor-type lifting structure and the telescopic support frame to rise synchronously; the lifting controller controls the first motor and the second motor to rotate synchronously in the reverse direction, and the scissor arm assembly extends laterally, causing the top of the scissor-type lifting structure to fall, and the telescopic support frame retracts longitudinally, causing the scissor-type lifting structure and the telescopic support frame to fall synchronously; when the scissor-type lifting structure and the telescopic support frame move to a preset height, the motor stops, and the telescopic support frame supports the flange platform, providing sufficient support force for the pantograph. Preferably, the lifting assembly further includes a limit switch. The limit switch is disposed on the flange platform and is communicatively connected to the lifting controller. When the lifting controller controls the telescopic support frame and the scissor-type lifting structure to rise to the maximum height, the limit switch locks them.

[0043] A specific application example of this invention is: When vehicles of the electrified highway transport system are running on the line, the electrified highway dispatch system prompts the driver through the main display screen that the vehicle has entered the high catenary area. The driver presses the "lift" switch on the control panel in the cab. The lifting controller receives the instruction and controls the pantograph in the lowered position to rise as a whole. The scissor lift structure amplifies the stroke. After the pantograph rises to the preset height, the motor stops, and the support frame provides support to ensure that the pantograph is in a stable state.

[0044] Another specific application example of the present invention is: After the driver supplies power via the EV switch on the cab control panel of the electrified highway transport system vehicle, they press the "Raise" toggle switch to raise the pantograph to a preset height. At this point, the lowest pantograph arm height in the lowered position is greater than the maximum maintenance tilting height of the cab below the pantograph arm. Then, pressing the "Tilt" toggle switch controls the cab to tilt. The cab will not collide with the pantograph arm during tilting, allowing maintenance personnel to inspect or maintain components such as the VCU controller under the cab. Because there is no need to raise the pantograph and then cut off the power, the potential hazards associated with automatic pantograph lowering are eliminated, improving maintenance safety.
