Description

Technical Field

[0001] The present invention relates to the technical field of rail vehicle braking systems, in particular to a device and method for preventing a coke oven rail vehicle from slipping in rainy days. Background Art

[0002] Zhanjiang Steel's JNX70-2 coke oven railcars consist of a coal loading car, a coke pusher car, a coke guide car, and a tram, collectively known as the "four major cars." These cars operate on open-air horizontal tracks in a 2-1 tandem operation. Their primary functions are to load coal into the carbonization chamber and, once the coke is mature, push the coke out and transport it to the dry coke quenching traction unit. Like most railcars, these coke oven cars are powered by sliding rails and driven by an electric motor with variable frequency speed regulation. The entire drive system consists of a variable frequency motor, a brake, a coupling with a brake wheel, and a hollow bevel gear reducer.

[0003] Coke oven rail cars are equipped with coarse and fine positioning systems. Each coking chamber and maintenance location is equipped with a unique target plate. The vehicle stops when a reader detects the target plate. A rotary encoder is installed on one of the running wheels of each coke oven rail car. This, combined with the reader and the precise positioning of the target plate, enables automatic and accurate alignment, with a required accuracy of ±5mm.

[0004] The current invention has the following main problems in production practice:

[0005] Coke oven rail vehicles operate for extended periods, and dust accumulates on the track surface. The repeated friction between the track and wheels compacts the dust, causing it to adhere to the track surface. Coke oven machinery is located outdoors, and during production, it is subject to rain and snow. The dust adhering to the track surface becomes damp, forming a sticky substance that reduces the friction between the wheels and the track. In rainy and snowy weather, vehicles often skid after braking, resulting in precise misalignment. When two vehicles operating on the same track are close together, braking can cause the wheels to lock, but the friction between the wheels and the track is reduced, allowing the vehicles to continue skidding and potentially causing a collision, posing a significant safety hazard.

[0019] A method for preventing a coke oven rail vehicle from slipping in rainy days comprises the following steps:

[0020] S1. When it rains, the rain sensor installed in the driver's cab of the coke oven vehicle converts the light intensity or capacitance change into an electrical signal, transmits it to the control module, and starts the device. Then, the electric hydraulic booster is energized and the motor drives the impeller to rotate, causing the piston to push the push rod and connecting rod downward;

[0021] S2, the cleaning head descends with the connecting rod and contacts the track, and begins to clean the dust on the track surface. At the same time, after the movable block contacts the track, it presses the spring upward, driving the first rotating rod, the support rod and the second rotating rod to move, causing the clamping plate to rotate toward the side of the track. Finally, the abutment block contacts the side of the track and provides additional friction.

[0022] S3. During vehicle operation, the control system adjusts the working pressure of the electric hydraulic booster in real time based on parameters such as vehicle speed and wheel speed difference to adapt to different driving conditions;

[0023] S4. When the vehicle needs to stay on the track for a long time, the operator can drive the driving motor to rotate the transmission helical gear. When the transmission helical gear rotates, the driven helical gear rotates, which in turn rotates the threaded rod, driving the adjustment slider to slide in the first slide groove, further adjusting the position of the sleeve, thereby fine-tuning the clamping force of the clamping plate on the track;

[0024] S5. When the weather clears or the track becomes dry, the rain sensor transmits a signal to the control module, shutting down the device. The electric hydraulic booster then lifts upward, the spring resets, driving the movable block downward, the splint detaches from the side of the track, and the cleaning head rises and detaches from the track surface.

[0025] (3) Beneficial effects

[0026] The present invention provides a device and method for preventing coke oven rail vehicles from slipping in rainy days, which has the following features:

[0027] Beneficial effects:

[0028] (1) The present invention achieves the purpose of preventing the coke oven rail vehicle from slipping on rainy days by fixing a base on the outer surface of the vehicle body, and sequentially arranging an electric hydraulic booster, a connecting rod, a shell, a cleaning head, and a series of structures such as a limit connecting rod and a sleeve on the right side of the shell. This design uses an electric hydraulic booster to drive the cleaning head to descend and clean the dust accumulated on the track. At the same time, the clamping plate is abutted against the side of the track through the limit connecting rod, the sleeve and the related linkage structure, thereby increasing the friction between the vehicle body and the track, thereby reducing the sliding of the vehicle body after braking on rainy days, avoiding precise positioning errors and vehicle body collision accidents, and improving the safety and reliability of the coke oven rail vehicle running system.

[0029] (2) The present invention arranges ball bearings at both ends of the support rod to respectively connect the first rotating rod and the second rotating rod, and the wheels, cleaning head and movable block are on the same horizontal line and located on the upper surface of the track. At the same time, the cleaning head is made of rubber and bakelite, which achieves the effect of optimizing the performance of the device. The arrangement of ball bearings reduces the friction between the rotating parts, making the splint rotate more smoothly. In addition, the material combination of the cleaning head takes into account wear resistance, flexibility resistance, load-bearing performance and buffering performance, which not only extends the service life of the cleaning head, but also enhances its cleaning and anti-skid capabilities, further ensuring the safety of the vehicle running on rainy days.

[0030] (3) By arranging a driving motor, a transmission bevel gear, a driven bevel gear, a threaded rod, an adjusting slider and other adjusting structures on the outer shell, when the vehicle stays on the track surface for a long time, the transmission bevel gear can be driven to rotate by the output end of the driving motor, and then the transmission bevel gear drives the driven bevel gear to rotate, and then the threaded rod is rotated to achieve the effect of adjusting the distance between the sleeve and the upper surface of the track, and then the clamping force of the splint is adjusted, which can reduce the precise positioning errors caused by the coke oven rail vehicle due to slipping and sliding after braking, and avoid vehicle collision accidents caused by the vehicle continuing to slide after braking, thereby improving the safety and reliability of the coke oven rail vehicle running system, thereby stabilizing the coke oven production.

DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] like Figure 1-10 As shown, the present invention provides a technical solution: a device for preventing a coke oven rail vehicle from slipping in rainy days, comprising a vehicle body 1, a base 3 fixedly connected to the outer surface of the vehicle body 1, an electric hydraulic booster 4 provided at the bottom of the base 3, a connecting rod 5 provided at the bottom of the electric hydraulic booster 4, a shell 6 provided at the bottom of the connecting rod 5, a cleaning head 7 provided at the bottom of the shell 6, a limit connecting rod 9 provided on the right side of the shell 6, and a sleeve 10 provided on the right side of the limit connecting rod 9;

[0044] The sleeve 10 is symmetrically provided with second sliding grooves 12 on both sides. A limit slider 21 is slidably connected in the second sliding groove 12. One end of the limit slider 21 located outside the sleeve 10 is fixedly connected to a second rotating rod 22.

[0045] The bottom of the front and back sides of the sleeve 10 are symmetrically provided with a rotating seat 13, and the inner wall of the rotating seat 13 is provided with a rotatable movable rod 14. The end of the movable rod 14 away from the rotating seat 13 is fixedly connected to the clamping plate 15, and the inner side of the clamping plate 15 is provided with an abutment block 16. A movable movable block 17 is provided inside the sleeve 10, and the end of the clamping plate 15 away from the movable rod 14 is fixedly connected to the first rotating rod 18. The outer wall of the first rotating rod 18 is provided with a rotatable support rod 19, and the support rod 19 is respectively connected to the first rotating rod 18 and the second rotating rod 22. By fixing the base 3 on the outer surface of the vehicle body 1 and sequentially arranging electric hydraulic boosters at the bottom of the base 3 The device is composed of a series of structures such as a device 4, a connecting rod 5, a shell 6, a cleaning head 7, and a limit connecting rod 9 and a sleeve 10 arranged on the right side of the shell 6, which achieves the purpose of preventing the coke oven rail vehicle from slipping on rainy days. This design uses the electric hydraulic booster 4 to drive the cleaning head 7 to descend and clean the dust accumulated on the track 8. At the same time, the clamping plate 15 is abutted against the side of the track 8 through the limit connecting rod 9, the sleeve 10 and the related linkage structure, which increases the friction between the vehicle body 1 and the track 8, thereby reducing the sliding of the vehicle body 1 after braking on rainy days, avoiding precise positioning errors and collision accidents of the vehicle body 1, and improving the safety and reliability of the coke oven rail vehicle running system.

[0046] Furthermore, ball bearings are provided at both ends of the support rod 19, and the first rotating rod 18 and the second rotating rod 22 are respectively inserted into the inner walls of the two ball bearings. The ball bearings can greatly reduce the friction during rotation, so that the first rotating rod 18 and the second rotating rod 22 are smoother during relative movement, reducing energy loss and component wear. At the same time, it ensures that the splint 15 can be quickly and stably rotated to a position that fits the side of the track 8 under the drive of the movable block 17. Even when the device is working frequently, it can maintain precise movement response, ensure that the abutment block 16 is in close contact with the side of the track 8, and continuously and stably provide additional friction, thereby effectively enhancing the anti-skid effect of the coke oven rail vehicle when driving in rainy days, and ensuring the safe operation of the vehicle body 1.

[0047] Furthermore, a wheel 2 is provided on the vehicle body 1, and a track 8 is provided at the bottom of the wheel 2. The wheel 2, the cleaning head 7, and the movable block 17 are on the same horizontal line and are all located on the upper surface of the track 8, so that the force transmission of the device is more direct and efficient when working. The cleaning head 7 is made of rubber and bakelite, and the bakelite is wrapped in the outer layer of rubber. The rubber itself has good elasticity and friction, which can effectively increase the friction coefficient with the track 8, and provide additional anti-slip force for the vehicle body 1 while cleaning the dust accumulated on the track 8; and bakelite has excellent wear resistance, and being wrapped in the outer layer of rubber can protect the rubber and extend the service life of the cleaning head 7, so that it is not easy to wear, deform and other problems during frequent cleaning of the track 8 and under pressure. The combination of the two not only ensures that the cleaning head 7 can stably clean the track 8, but also enhances the friction between the vehicle body 1 and the track 8 on rainy days, reduces the risk of the vehicle body 1 slipping, and ensures that the coke oven rail vehicle can operate safely and stably in rainy and snowy weather.

[0048] Furthermore, a first slide groove 11 is symmetrically provided on the right side of the shell 6, and the inner wall of the first slide groove 11 is slidingly connected to the limit connecting rod 9. A driving motor 20 is provided on the upper part of the back side of the shell 6. The sliding connection between the first slide groove 11 and the limit connecting rod 9 not only limits the movement trajectory of the limit connecting rod 9, making its movement more stable and precise, but also provides a guiding basis for a series of subsequent mechanical actions. The setting of the driving motor 20 becomes the key power source for the adjustment function of the device. When the vehicle body 1 needs to stay on the track 8 for a long time or faces different track 8 conditions, the driving motor 20 is started and drives the limit connecting rod 9 on the right side of the adjustment slider 28 to slide in the first slide groove 11 through a series of transmission structures (such as the transmission bevel gear 25, the driven bevel gear 26, and the threaded rod 27), thereby adjusting the position of the sleeve 10, and realizing fine-tuning of the clamping force of the splint 15, effectively enhancing the friction between the vehicle body 1 and the track 8 under different conditions, reducing the slippage of the vehicle body 1, improving the safety and stability of the operation of the coke oven rail vehicle, and ensuring the smooth progress of coke oven production.

[0049] Furthermore, a transmission bevel gear 25 is provided at one end of the driving motor 20 located inside the housing 6, and the outer wall of the transmission bevel gear 25 is meshedly connected with a driven bevel gear 26, and the inner wall of the driven bevel gear 26 is provided with a threaded rod 27. The outer wall of the threaded rod 27 is rotatably connected with an adjusting slider 28, and a docking plate 29 is provided on the right side of the limiting connecting rod 9. The adjusting slider 28 has a rectangular shape, and the outer diameter of the adjusting slider 28 matches the inner diameter of the housing 6. The driving motor 20 drives the transmission bevel gear 25 to rotate. When the transmission bevel gear 25 rotates, it drives the driven bevel gear 26 to rotate together, and then drives the threaded rod 27 to rotate, and then drives the rectangular and size-matched adjusting slider 28 to move in the housing 6. The adjusting slider 28 cooperates with the docking plate 29 on the right side of the limiting connecting rod 9 to achieve precise adjustment of the position of the sleeve 10, thereby flexibly fine-tuning the clamping force of the splint 15 on the rail 8, enhancing the anti-slip effect of the vehicle body 1 under different working conditions, and ensuring the safe operation of the coke oven rail vehicle.

[0050] Furthermore, one end of the movable block 17 located inside the sleeve 10 is fixedly connected to a limiting plate 23. The limiting plate 23 has a rectangular shape, and the outer diameter of the limiting plate 23 matches the inner diameter of the sleeve 10. The limiting plate 23 is fixedly connected to the limiting slider 21. A spring 24 is provided on the upper surface of the limiting plate 23, which can accurately control the movement of the movable block 17. When the cleaning head 7 contacts the track 8, the movable block 17 squeezes the spring 24 upward, and the linkage structure allows the splint 15 to rotate toward the track 8 for clamping; when the device is closed, the spring 24 resets and drives the movable block 17 to move downward, so that the splint 15 can smoothly detach from the track 8, and the splint 15 can expand and stop clamping the track 8, ensuring that the device can efficiently and stably play an anti-slip role.

[0051] Furthermore, the abutment block 16 is made of natural rubber material, and the abutment block 16 is connected to the splint 15 by bolts. The good elasticity and friction of natural rubber can make the abutment block 16 fit tightly to the side of the track 8, greatly increasing the friction between the vehicle body 1 and the track 8, effectively preventing the vehicle body 1 from slipping, and the bolt connection method facilitates quick replacement of the abutment block 16 when the anti-slip effect is affected by wear, thereby reducing maintenance costs.

[0052] Furthermore, the axis of the spring 24 is perpendicular to the upper surface of the limit plate 23, and one end of the spring 24 is fixed at the center position of the limit plate 23, and the other end is fixedly connected to the top of the inner wall of the sleeve 10. When the device is working, it can accurately control the displacement of the movable block 17, thereby making the splint 15 rotate stably, ensuring that the abutment block 16 reliably abuts the side of the track 8. When the device is closed, the movable block 17 can also be smoothly reset to maintain the stability and reliability of the device operation.

[0053] A method for preventing a coke oven rail vehicle from slipping in rainy days comprises the following steps:

[0054] S1. When it rains, the rain sensor installed in the driver's cab of the coke oven vehicle converts the light intensity or capacitance change into an electrical signal, transmits it to the control module, and starts the device. Then, the electric hydraulic booster 4 is energized and the motor drives the impeller to rotate, causing the piston to push the push rod and connecting rod 5 downward;

[0055] When the cleaning head 7 is lowered with the connecting rod 5 to clean the dust on the surface of the track 8, the movable block 17 is pressed upward by the spring 24, which drives the first rotating rod 18, the support rod 19 and the second rotating rod 22 to move, so that the clamping plate 15 is rotated to the side of the track 8, and finally the abutting block 16 contacts the side of the track 8 and provides additional friction. It can be seen that when the cleaning head 7 is lowered with the connecting rod 5 to clean the dust on the surface of the track 8, the movable block 17 is synchronously in contact with the track 8 and presses the spring 24 upward. Through the linkage of the first rotating rod 18, the support rod 19 and the second rotating rod 22, the clamping plate 15 drives the abutting block 16 to fit closely with the side of the track 8, forming a "cleaning-clamping" cooperative working mechanism, which can not only effectively remove the dust that affects the friction force, but also provide additional friction through the abutting block 16 made of natural rubber, significantly enhancing the anti-skid ability of the vehicle body 1 in rainy days, and the adaptive structure of the rectangular limit plate 23 and the sleeve 10 ensures the stability of the movement of the movable block 17, further improving the reliability of the system;

[0056] S3. During the operation of the vehicle body 1, the control system adjusts the working pressure of the electric hydraulic booster 4 in real time according to parameters such as the speed of the vehicle body 1 and the speed difference of the wheels 2 to adapt to different driving conditions;

[0057] S4. When the vehicle body 1 needs to stay on the track 8 for a long time, the operator can drive the driving motor 20 to drive the transmission bevel gear 25 to rotate. When the transmission bevel gear 25 rotates, it drives the driven bevel gear 26 to rotate, and then the threaded rod 27 rotates, driving the adjustment slider 28 to slide in the first slide groove 11, further adjusting the position of the sleeve 10, thereby fine-tuning the clamping force of the clamping plate 15 on the track 8. By flexibly adjusting the clamping force according to actual needs, it is ensured that the vehicle body 1 is firmly docked on the track 8 when it stays for a long time, and effectively preventing safety accidents caused by accidental sliding of the vehicle body 1;

[0058] S5. When the weather clears up or the track 8 is dry, the rain sensor transmits a signal to the control module, shuts down the device, and then the electric hydraulic booster 4 is lifted upward, the spring 24 is reset, driving the movable block 17 to descend, the clamping plate 15 is separated from the side of the track 8, and the cleaning head 7 is lifted and separated from the surface of the track 8.

Then, the electric hydraulic booster (4) is powered on and the motor drives the impeller to rotate, causing the piston to push the push rod and the connecting rod (5) downward; S2, the cleaning head (7) is lowered along with the connecting rod (5) and contacts the track (8), and begins to clean the dust on the surface of the track (8). At the same time, after the movable block (17) contacts the track (8), it presses the spring (24) upward, driving the first rotating rod (18), the support rod (19) and the second rotating rod (22) to move, so that the clamping plate (15) rotates toward the side of the track (8), and finally the abutting block (16) contacts the side of the track (8) and provides additional friction; S3. During the operation of the vehicle, the control system adjusts the working pressure of the electric hydraulic booster (4) in real time according to parameters such as the vehicle speed and the speed difference of the wheels (2) to adapt to different driving conditions; S4. When the vehicle needs to stay on the track (8) for a long time, the operator can drive the driving motor (20) to drive the transmission bevel gear (25) to rotate. When the transmission bevel gear (25) rotates, the driven bevel gear (26) is driven to rotate, and then the threaded rod (27) is rotated to drive the adjustment slider (28) to slide in the first sliding groove (11), further adjusting the position of the sleeve (10), thereby fine-tuning the clamping force of the clamping plate (15) on the track (8); S5. When the weather clears up or the track (8) becomes dry, the rain sensor transmits a signal to the control module, shutting down the device. Then the electric hydraulic booster (4) is lifted upward, the spring (24) is reset, driving the movable block (17) to descend, the clamping plate (15) to separate from the side of the track (8), and the cleaning head (7) to rise and separate from the surface of the track (8).
