Description

Technical Field

[0001] This invention relates to the innovation and design of intelligent power improvement equipment for railway freight cars. Background Technology

[0002] The present invention, the intelligent power improvement equipment for railway freight cars, is an innovation and design aimed at addressing the problem of low transportation efficiency caused by the waste of a large amount of shunting time during shunting operations in railway transportation.

[0003] According to statistics, in 2022, the national railway freight volume was 5.035 billion tons, while the national road freight volume was 40.337 billion tons, approximately 8.01 times that of railway freight. Furthermore, the growth rate of road freight volume over the past 15 years has been 1.9 times that of railway freight. This is mainly because railway freight has lower timeliness compared to road freight, resulting in insufficient competitiveness. The primary reason for the lower timeliness of railway transportation is that nearly 70% of the total transportation time is spent on shunting operations and waiting for shunting within stations. The advantages of railway freight—large capacity, lower fares, transportation safety, and energy conservation—have gradually lost favor with shippers seeking faster and more economical transportation as the economy develops. Shippers now prefer the faster-moving road freight, even though it has lower safety and higher fares. In addition, the sheer size of railway freight equipment has led to extremely high upgrade costs, which has long been a bottleneck restricting the development of intelligent railway freight transportation.

[0004] Therefore, reducing shunting operation time and implementing intelligent shunting by changing a small number of railway freight cars has become a better option for improving railway shunting operations.

[0005] This invention enables intelligent shunting of railway freight cars by adding only a small amount of low-cost intelligent power improvement equipment without changing the existing railway freight car equipment. This improves the timeliness of railway transportation and is of great significance for reducing environmental pollution, energy waste, and traffic accident casualties caused by long-distance road transportation, as well as for achieving green and safe transportation. Summary of the Invention

[0006] The intelligent power improvement equipment for railway freight cars provided in this invention includes an energy acquisition device, an automatic coupling module, a power connection module, a hydraulic braking module, a power supply module, and a control center. This invention can use the energy acquisition device to acquire electrical energy from the contact wire and store the electrical energy in the power supply module to provide power for the operation of the automatic coupling module, the power connection module, and the hydraulic braking module.

The four rollers at both ends of the slide balance vehicle and the two side wheels on the main support rod form a stable triangular structure, which can ensure that the main support rod always remains vertical; the design of the slide balance vehicle is mainly to adapt to the zigzag arrangement of the contact wire of the contact network, so that the power acquisition equipment can always be located directly below the contact wire of the contact network;The rollers are bearing structures, with the inner ring of the bearing tightly connected to the connecting frame via the small wheel axle. The rollers are located at both ends of the scooter, and the outer ring of the bearing is used to roll on the base of the scooter, enabling the left and right movement of the support rod installed on the scooter. The anti-jamming wheel is also a bearing structure, with its inner ring tightly connected to the connecting frame via the small wheel axle. The anti-jamming wheel is located on the upper side of the scooter, and its outer ring is used to roll between the front and rear sides of the scooter base, reducing the frictional force between the scooter and the front and rear sides of the scooter base. The connecting frame is the main support part of the scooter, used to install the small wheel axle, the mounting base, the anti-jamming wheel, and the roller; the mounting base is located in the middle part of the connecting frame, used to connect and install the telescopic motor and gear set A and the support main rod; the telescopic motor and gear set A are installed inside the bottom of the support main rod, and the support main rod is fixedly connected to the mounting base; the inside of the support main rod is hollow, the bottom is used to install the telescopic motor and gear set A, and the middle and upper part is used for the telescopic tube A; the telescopic motor and gear set A are located at the bottom inside the support main rod, and the motor in the telescopic motor and gear set A can drive the gear set to rotate. The output end of the motor and gear set A is connected to the lead screw via gear meshing, and can drive the lead screw to rotate. A screw is provided on the outer surface of the lead screw, which can mesh with the thread on the inner surface of the telescopic rod A. When the lead screw rotates, the telescopic rod A retracts or extends, similar in principle to how a rotating screw pushes a stationary nut to move back and forth. The telescopic motor and gear set A works on the same principle as telescopic motors and gear sets B and C, and has a similar structure. The telescopic tube A is installed inside the main support rod, and the telescopic rod A is located inside the telescopic tube A.

The servo motor A is installed on the left front side of the fixed head and is fixedly connected to the return rod A via the servo motor shaft. Under the control of the power acquisition control module, the rotation of the servo motor shaft drives the return rod A to rotate. The return rod A is fixedly installed on the servo motor A via the servo motor shaft, and rotates under the drive of the servo motor A. The return rod A is made of insulating material and interacts with the contact wire of the contact network, i.e., through the return rod... A and the return rod B rotate upwards to adjust the position of the sliding balance vehicle, so that the mounting arm is directly below the contact wire of the contact network. The servo motor B is installed on the right front side of the fixed head and is fixedly connected to the return rod B through the servo motor shaft. Under the control of the power acquisition control module, the rotation of the servo motor shaft drives the return rod B to rotate. The return rod B is fixedly mounted on the servo motor through the servo motor shaft and is used to rotate under the drive of the servo motor B. The return rod B is made of insulating material and is used to interact with the contact wire of the contact network. That is, by rotating the return rods A and B upwards, the contact wire of the contact network is just clamped between the return rods A and B. Between points B, the position of the slide balance vehicle on the slide base is adjusted so that the mounting arm is directly below the contact line of the contact network; when the power acquisition device (0-01) is raised, the height of the ends of the return rods A and B after upward rotation is much higher than the contact line of the contact network; the servo motor C is installed and fixed on the left rear side of the fixed head, and is fixedly connected to the mounting arm through the servo motor shaft.

Under the control of the control module, the rotation of the servo shaft drives the mounting arm to rotate, keeping the mounting arm parallel to the contact line of the contact network. That is, the servo shafts of servo motors C and D are installed in opposite directions, but work synchronously, working together to rotate the mounting arm to a position parallel to the contact line of the contact network. One end of the servo shaft is respectively installed at the output end of servo motors A, B, C, and D.

[0010] One end of the hook support is fixedly installed on the end wall of the railway freight car, forming a "U"-shaped groove for mounting the telescopic motor and gear set B, the telescopic tube B, the slide rod, and the telescopic rod B. The telescopic groove is located inside the hook support, reserving space for the telescopic movement of the telescopic rod B. The end of the telescopic groove is used to install the slide rod. The slide rod is installed on the telescopic groove at the end of the hook support, and the telescopic groove vertically below the slide rod is hollowed out to allow the hook chain to pass through. The hook chain is made of flexible and wear-resistant material, with one end connected to the hook chain hole and the other end... Connected to the hook-lifting lock of the coupler, the hook-lifting lock can be pulled up when the telescopic rod B retracts, thereby lifting the coupler. At this time, the power connection module needs to cooperate to put the coupler into a compressed state. The telescopic motor and gear set B are installed at one end of the telescopic groove of the hook support. The motor of the telescopic motor and gear set B can drive the gear set to rotate. The output end of the telescopic motor and gear set B is connected to the lead screw through gears and can drive the lead screw to rotate. The lead screw is located inside the telescopic rod B, and the outer surface of the lead screw is provided with screws that can be connected to the inner surface of the telescopic rod B. The telescopic rod B is threaded and meshes with the screw, allowing it to extend and retract under the rotation of the screw. Its working principle is similar to that of a rotating screw pushing a stationary nut back and forth. One end of the telescopic tube B is fixedly connected to one end of the telescopic motor and gear set B. The interior of the telescopic tube B houses the telescopic rod B, providing a stable environment for its extension and retraction. The telescopic rod B is hollow inside, with threads on its inner surface that mesh with the screw, enabling it to extend and retract under the rotation of the screw. The hook chain hole is located at the end of the telescopic rod B and is used to engage with the lifting hook chain. The end is fixedly connected, and the other end of the hook chain hole is connected to the hook locking iron of the coupler; the hook lifting control module is used to control the working state of the telescopic motor and gear set B; when the automatic hook lifting module performs intelligent hook lifting operation, the power connection module of the vehicle where the equipment is located first needs to work and move towards the vehicle to be hooked, so that the two couplers are in a compressed state. At this time, the hook lifting control module controls the telescopic motor and gear set B to move, the telescopic rod B retracts and pulls the hook lifting chain through the hook chain hole, changes the direction of the pulling force at the slide rod, and pulls up the hook locking iron of the coupler to complete the intelligent hook lifting operation.

[0011] The gear axle is divided into two halves, one end of which is fixedly connected to the gear auxiliary. It has a semi-circular groove inside, with the middle section for tightly embedding the axle. The connection is secured with screws and nuts through the gear auxiliary holes on the gear auxiliary. The gear auxiliary is also divided into two halves, one end of which is fixedly connected to the gear axle. It has a semi-circular groove inside, with the middle section for tightly embedding the axle. The connection is secured with screws and nuts through the gear auxiliary holes on both sides of the gear auxiliary. Screws and nuts are inserted to tightly connect the two halves of the gear axle and the gear auxiliary. The meshing gear is mounted on the reduction shaft and can engage with... The axle gear meshes and matches, and the meshing gear can rotate through the reduction shaft. When the meshing gear meshes with the axle gear, it can drive the axle gear to rotate together. The design of the axle gear and the gear auxiliary is the key to the power improvement of existing railway axles, avoiding the need to redesign existing axles. Existing axles can be connected to the reducer simply by adding the axle gear and the gear auxiliary, thus completing the vehicle's power improvement. The base mounting frame is installed and fixed to the bottom of the railway freight car, used to connect the rotating male head, the rotating female head, the rotating shaft, the telescopic motor and gear set C, and the... The telescopic tube C, the telescopic rod C, and the rotating frame are connected. The base mounting frame and the lithium battery mounting frame are fixedly connected, all located at the bottom of the vehicle. The rotating frame is used to mount the motor and the reducer. Through the telescopic movement of the telescopic rod C, the rotating frame rotates around one end of the base mounting frame to achieve the meshing and disengagement of the meshing gear and the wheel axle gear. The rotating male head is respectively installed at the end of the rotating frame, the telescopic rod C, the telescopic motor, and the gear set C. It can be connected to two rotating female heads through the rotating shaft to form a hinged rotation operation. The rotating female heads are respectively installed on the rotating... At both ends of the frame and the base mounting frame, two rotating female heads can be matched and connected to one rotating male head through the rotating shaft to form a hinge for rotational operation; the rotating shaft is used to insert into the holes provided on the rotating male head and the rotating female head and connect them together; the motor is mounted on the rotating frame, and its output end is connected to the input end of the reducer through gear meshing, so as to provide power for the self-movement of the railway freight vehicle using the power provided by the power module; the reducer is mounted on the rotating frame, and its input end is connected to the output end of the motor through gear meshing, so as to amplify the rotational torque provided by the motor and output it to the reduction shaft;The telescopic motor and gear set C have the rotating male head fixedly mounted on one end, and the other end fixedly connected to the telescopic tube C. The output end of the motor in the telescopic motor and gear set C is connected to the input end of the gear set through gear meshing, and the motor can drive the gear set to rotate. The output end of the gear set is connected to a lead screw through gear meshing, and can drive the lead screw to rotate. The lead screw is located inside the telescopic rod C, and a screw is provided on the outer surface of the lead screw, which can match and mesh with the thread provided on the inner surface of the telescopic rod C. The rotation of the lead screw can drive the telescopic rod C to extend and retract. The telescopic rod C operates on a principle similar to that of a rotating screw driving a non-rotating nut to extend and retract. One end of the telescopic tube C is fixedly connected to the telescopic motor and gear set C, providing constraints for the telescopic rod C's extension and retraction, ensuring that the telescopic rod C remains stationary through a slot in the telescopic tube C during its extension and retraction. The telescopic rod C is internally hollow, with threads on its inner surface, allowing it to mesh with the lead screw and enabling the telescopic rod C to extend and retract vertically during the rotation of the lead screw. The rotating male end of the telescopic rod C is installed at its end. The vertical extension and retraction of lever C is crucial for the rotation of the rotating frame and also for the power connection module to switch between providing power and not providing power. The axle is part of the original structure of the railway freight vehicle and is used to mount the axle gear and the gear auxiliary. The reduction shaft is connected and fixed to the output end of the reducer, and the meshing gear is mounted on the reduction shaft, which can drive the meshing gear to rotate together. The power switching control module is used to control the operation of the telescopic motor and gear set C to realize the engagement or disengagement of the meshing gear and the axle gear; that is, when the freight vehicle needs to be shunted... During operation, the power switching control module receives instructions from the control center and controls the telescopic motor and gear set to operate, causing the telescopic rod C to extend. The meshing gear engages with the wheel axle gear, and the motor drives the reducer and the reduction shaft to rotate, which in turn drives the meshing gear and the wheel axle gear to rotate. Ultimately, this causes the vehicle's wheel axle to rotate, completing the vehicle's intelligent shunting operation. When the vehicle needs to stop, the telescopic rod C can be retracted or the motor can be stopped. At this time, it can also work in conjunction with the hydraulic braking module to quickly and efficiently complete the braking process.

[0012] The hydraulic press is installed at the connection between the base mounting frame and the lithium battery mounting frame, and is used to provide sufficient hydraulic pressure to the hydraulic lever using the electrical energy provided by the lithium battery module. The hydraulic lever contains a hydraulic telescopic rod, which is used to extend and retract using the hydraulic pressure provided by the hydraulic press. The hydraulic telescopic rod is located inside the hydraulic lever and has a base brake connection hole at its end, used to realize the extension and retraction of the hydraulic brake module, and then drive the vehicle's basic braking device through the base brake connection hole to achieve self-braking of the vehicle. The base brake connection hole is located at the end of the hydraulic telescopic rod and is used to connect to the vehicle's basic braking device. The hydraulic brake control module controls the operation of the hydraulic press, and thus controls the vehicle's braking state. When the vehicle needs to brake, the control center processes the received control commands and sends them to the hydraulic brake control module. The hydraulic brake control module controls the hydraulic press to provide hydraulic pressure to the hydraulic cylinder, thereby pushing or pulling the hydraulic telescopic rod, and then driving the vehicle's basic braking device through the base brake connection hole, ultimately causing the brake shoes to press tightly against the vehicle's wheels, completing the intelligent braking process.

[0013] The lithium battery mounting bracket and the base mounting bracket are integrated and installed at the bottom of the railway freight car for mounting the lithium battery module housing. The design of the lithium battery mounting bracket and the base mounting bracket is to facilitate the modification of railway freight cars. The lithium battery module is placed in the lithium battery module housing to store the electrical energy acquired by the power acquisition device and to provide power for the operation of all equipment in the intelligent power improvement equipment for railway freight cars. The lithium battery module housing is used to house the lithium battery module and the intelligent power charging and discharging control module, and to protect them. The intelligent power charging and discharging control module is used to intelligently protect the lithium battery module, that is, the device automatically cuts off power and stops charging after the device is fully charged.
