Description

Technical Field

[0001] The invention relates to the technical field of coke quenching car bogies, in particular to an intelligent coke quenching car bogie with balancing and stabilizing functions. Background Art

[0002] As a supporting equipment for large coke ovens in chemical plants, the quenching car usually runs on the track below the coke side of the coke oven. Its core functions include: receiving the coke at about 1,000 degrees Celsius exported by the coke guide car, transporting it to the quenching chamber for quenching, and transporting the quenched coke to the designated location. The quenching car bogie is a vital component of the quenching car's traveling mechanism. The mechanism is usually composed of key structural elements such as the frame, axle box, wheel set, brake device and vibration reduction device.

[0003] The bogie of the quenching car running on the rails mainly achieves steering through the differential speed of the inner and outer wheels. At present, the design of most transmission bridges is based on the passive differential mechanism of the quenching car steering. The differential speed of the inner and outer wheels caused by this mechanism is not accurate and timely, which can easily cause the quenching car to lose steering balance and derail. The quenching car itself has a large mass and volume. Once imbalance occurs, the loss will be very serious. In addition, due to the heavy weight of the quenching car and the uneven weight distribution, the conventional shock absorption system is difficult to effectively prevent the risk of the quenching car rolling over. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent coke quenching car bogie with balancing and stabilizing functions to solve the problems in the prior art.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: A bogie for an intelligent coke quenching car with a balancing and stabilizing function comprises a frame, a wheelset, an intelligent chip box, a synchronization mechanism, a braking mechanism and a shock absorbing mechanism. The frame is rotatably connected to the wheelset. The synchronization mechanism comprises a connecting frame, a synchronous motor, a transmission mechanism and a detection mechanism. The transmission mechanism comprises a servo motor. The braking mechanism comprises a side frame, a first cylinder and a brake disc. The shock absorbing mechanism comprises a bridge frame. The intelligent chip box and the side frame are fixedly connected to the frame. The detection mechanism comprises a housing, a first sensor and a second sensor. The brake disc is fixedly connected to the wheelset and the housing. The connecting frame and the synchronous motor are fixedly connected to the bridge frame. The intelligent chip box is connected to the synchronous motor, the servo motor, the first sensor, the second sensor and the first cylinder through electrical signals.

[0006] The present invention is an intelligent traveling assembly bogie for a coke quenching car. The coke quenching car itself is a special vehicle supporting large coke ovens with large mass and volume. When walking on rails and turning, it is necessary to maintain a precise differential speed between the inner and outer wheel pairs to ensure smooth turning. The synchronous motor outputs torque to the transmission mechanism to drive the wheel pairs on both sides to walk on the rails. The detection mechanisms, brake discs and wheel pairs on both sides are connected through the transmission mechanism. When the coke quenching car turns on the rails, the first sensor and the second sensor detect the posture change of the coke quenching car and send an electrical signal to the intelligent chip box. The intelligent chip box analyzes the steering angle and acceleration of the quenching car at this time, and determines the most suitable accurate differential speed for the wheelsets on both sides. When there is a differential speed due to the rolling friction between the wheelsets on both sides and the rails, the servo motor actively adjusts and compensates the differential speed between the wheelsets on both sides according to the electrical signal of the intelligent chip box to make it adapt, ensuring the balance and stability of the quenching car when turning. The load distribution of the quenching car itself is analyzed through the shock absorbing mechanism, and the degree of damping rebound arranged at each point is adjusted to avoid excessive deviation caused by uneven weight distribution when the quenching car vibrates, thereby eliminating the hidden danger of rollover of the quenching car.

[0007] Furthermore, the synchronization mechanism also includes a bevel gear head, a first connecting rod and a second connecting rod. The detection mechanism is provided with two groups, and the two groups of detection mechanisms are arranged on both sides of the transmission mechanism. The outer shell is fixedly connected to the first connecting rod and the second connecting rod. The transmission mechanism also includes a drum shell and a bevel gear disk. The drum shell is fixedly connected to the connecting frame. The drum shell is provided with a first through hole, a second through hole and a side hole. The first connecting rod is rotatably connected to the first through hole, and the second through hole is rotatably connected to the second connecting rod. The output end of the synchronous motor is fixedly connected to the bevel gear head, and the bevel gear head is rotatably connected to the side hole. The bevel gear head is meshed with the tooth surface of the bevel gear disk.

[0008] When traveling in a straight line, the synchronous motor outputs torque to the bevel gear head, which rotates in the side hole, and transmits torque through the meshing of the tooth surfaces of the bevel gear head and the bevel gear disc. The bevel gear disc drives the first connecting rod to rotate in the first through hole, and the second connecting rod to rotate in the second through hole, thereby driving the wheels on both sides to drive synchronously. When the first sensor and the second sensor detect stalling or overspeeding caused by load or slippage between the wheels and the rails, the synchronous motor intelligently adjusts the output torque and reduces the speed to ensure the stable driving of the coke quenching car.

[0009] Furthermore, the transmission mechanism also includes a chassis, a first bevel gear, a second bevel gear, a third bevel gear, a fourth bevel gear, and a spring seat. The chassis is fixedly connected to the first connecting rod and the bevel gear plate. The bevel gear plate is provided with assembly holes. There are two groups of assembly holes and spring seats. The two groups of assembly holes are rotatably connected to the spring seat. The first bevel gear is meshed with the third bevel gear and the fourth bevel gear. The third bevel gear and the fourth bevel gear are fixedly connected to the spring seat. The second bevel gear is meshed with the third bevel gear and the fourth bevel gear. The second bevel gear is fixedly connected to the second connecting rod.

[0010] When driving in a straight line, the torque is transmitted through the meshing of the bevel gear head and the tooth surface of the bevel gear disc. The bevel gear disc drives the first connecting rod to rotate in the first through hole through the assembly chassis. The bevel gear disc drives the third bevel gear and the fourth bevel gear to revolve around the axis of the second bevel gear through the assembly hole. Due to the friction between the third bevel gear, the fourth bevel gear and the second bevel gear, the second bevel gear is driven to rotate around its own axis to make the second connecting rod rotate in the second through hole. When turning, the inner side of the turning angle is assumed to be the second connecting rod, and the friction of the rail is relieved by the wheelset on the inner side of the turning angle. In order to make the quenching car turn smoothly, there is a passive differential between the inner and outer sides at this time, and the second connecting rod drives the second bevel gear to rotate in the opposite direction, and the meshing of the tooth surface of the second bevel gear engages with the first The third bevel gear and the fourth bevel gear, the third bevel gear and the fourth bevel gear tooth surface engage with the first bevel gear, so that the third bevel gear and the fourth bevel gear rotate around their axes in the assembly hole, the third bevel gear and the fourth bevel gear rotate in opposite directions with the same speed, the first bevel gear rotates on the chassis, at this time the first connecting rod still transmits torque through the bevel gear plate and the chassis, there is a differential between the first connecting rod and the second connecting rod, the servo motor actively outputs torque according to the electrical signal of the smart chip box, drives the fourth bevel gear to rotate, and engages the second bevel gear through the self-rotating tooth surface of the fourth bevel gear, compensates and adjusts the speed of the second connecting rod, so that the differential between the first connecting rod and the second connecting rod meets the optimal speed for the turning angle adaptation at this time.

[0011] Furthermore, the detection mechanism also includes an arc frame, a first inner ring, a second inner ring, an assembly frame, a first motor and a bearing flywheel. The arc frame is rotatably connected to the outer shell, the first sensor is fixedly connected to the arc frame, the first inner ring is rotatably connected to the arc frame, the first sensor and the second inner ring, the second sensor is fixedly connected to the first inner ring, the second inner ring is rotatably connected to the second sensor, the assembly frame is fixedly connected to the second inner ring and the first motor, and the output end of the first motor is fixedly connected to the bearing flywheel.

[0012] Before the quenching car moves, the first motor outputs initial torque to the bearing flywheel, causing the bearing flywheel to start rotating at high speed. In the absence of external force, the angular velocity and direction of the bearing flywheel remain unchanged, and it has a tendency to resist direction change. Inside it, the first inner ring can rotate around the arc frame, and the second inner ring rotates around the first inner ring, forming a three-dimensional coordinate system inside. When the quenching car turns or accelerates, the arc frame will rotate with the quenching car. When the bearing flywheel receives an external torque, the momentum vector of the bearing flywheel will catch up with the external torque at the minimum speed, causing the bearing flywheel to move in the direction of the external torque along the axis where the angular momentum is located. The bearing flywheel drives the first inner ring and the second inner ring to deflect. This rotation can be detected by the first sensor and the second sensor, and an electrical signal is sent to the smart chip box, thereby determining the acceleration state and turning angle of the quenching car.

[0013] Furthermore, the braking mechanism also includes an articulated frame and a spring caliper. The first cylinder and the articulated frame are fixedly connected to the side frame. The output end of the first cylinder is fixedly connected to the spring caliper. The spring caliper is hinged to the articulated frame, and the spring caliper is in contact with the brake disc.

[0014] The quenching car completes braking through the braking mechanism set in the unit. The brake disc is fixedly assembled on the wheel set. When braking is required, the output end of the first cylinder pushes the spring caliper on the articulated frame to engage. The spring caliper engages and contacts the brake disc, and the kinetic energy of the brake disc is converted into the internal energy of the spring caliper and the brake disc through friction, thereby achieving the braking effect.

[0015] Furthermore, the shock absorbing mechanism also includes a pressure-sensing mechanism, a support plate and a damping mechanism. The pressure-sensing mechanism includes a pressure sensor, a base and a second cylinder. The damping mechanism is provided with several groups, and the several groups of damping mechanisms are respectively arranged at both ends of the bridge frame. The damping mechanism includes an outer oil cylinder, an assembly plate and an adjustable oil valve. The base and the outer oil cylinder are fixedly connected to the bridge frame, the assembly plate is fixedly connected to the support plate, and the pressure sensor and the second cylinder are connected to the adjustable oil valve through electrical signals.

[0016] The quenching car body is assembled on the pressure-sensing mechanism and the support plate. The pressure sensor assembled on the pressure-sensing mechanism identifies the weight distribution in the box body and sends an electrical signal to the adjustable oil valve in the damping mechanism at the corresponding position. In the area with heavy weight, the adjustable oil valve increases the rebound damping of the damping mechanism at the corresponding position. Increasing the rebound damping can more effectively absorb and consume vibration energy, so that the object can recover to a stable state more quickly after being subjected to external impact, thereby reducing the amplitude and duration of vibration, and avoiding the quenching car from overturning due to excessive amplitude in the area with heavy load.

[0017] Furthermore, the pressure sensing mechanism also includes a pressure plate and a ball head rod, the pressure sensor is fixedly connected to the pressure plate and the ball head rod, a first hinged buckle is provided on the pressure plate, a ball cavity and a second hinged buckle are provided on the base, the first hinged buckle, the second hinged buckle and the second cylinder are each provided with several groups, several groups of first hinged buckles are evenly distributed along the circumference of the pressure plate, several groups of second hinged buckles and second cylinders are evenly distributed along the circumference of the base, the ball head rod is in contact with the ball cavity, and the second cylinder is hinged to the first hinged buckle and the second hinged buckle.

[0018] The quenching car body is assembled on the pressure plate. After the material is loaded inside the box, since the weight is not evenly distributed inside the box, the pressure plate will shift to the area with heavy weight. At this time, the ball head rod rotates in the ball cavity, and the pressure value recorded by the pressure sensor is changing. Several groups of second cylinders evenly distributed along the circumference of the base are pulled. By combining the difference in the pulling of several groups of second cylinders, the angle of the ball head rod offset can be effectively obtained, and then the direction of the heavy weight area can be determined. Through the speed of change of the pressure value of the pressure sensor and the angle of the ball head rod offset, the difference between the heavy weight area and the light weight area inside the box can be finally calculated. The difference ultimately determines the rebound damping that the damping mechanism needs to increase.

[0019] Furthermore, the damping mechanism also includes an inner oil cylinder, an outer spring and a piston rod. The outer oil cylinder is provided with a first sliding hole, the inner oil cylinder is provided with a second sliding hole, the piston rod is fixedly connected to the assembly disk and the adjustable oil valve, the piston rod is slidably connected to the first sliding hole and the second sliding hole, the inner oil cylinder is slidably connected to the outer oil cylinder, and the outer spring is fixedly connected to the assembly disk and the outer oil cylinder.

[0020] The support plate distributes the weight on each group of damping mechanisms. When the quenching car vibrates, the support plate squeezes the outer spring and converts the kinetic energy of vibration into the internal energy of the outer spring. When the outer spring recovers its deformation, it pulls the piston rod to slide in the inner oil cylinder toward the support plate. The hydraulic oil in the inner oil cylinder passes through the adjustable oil valve, and the inner oil cylinder slides in the outer oil cylinder. The resistance of the hydraulic oil converts the kinetic energy of the outer spring recovering its deformation into the internal energy of the hydraulic oil. When it is necessary to increase the rebound damping, the adjustable oil valve reduces the amount of oil passing through, and the flow speed of the liquid will slow down, thereby increasing the flow resistance and increasing the damping.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention designs a detection mechanism, the first motor outputs an initial torque, so that the bearing flywheel starts to rotate at a high speed, and when there is no external force, the angular velocity and direction of the bearing flywheel remain unchanged, resisting direction changes, the quenching car turns, the bearing flywheel receives an external torque, and the angular moment vector of the bearing flywheel will catch up with the external torque at the minimum speed, so that the bearing flywheel moves in the direction of the external torque along the axial direction where the angular momentum is located, and this rotation can be detected by the first sensor and the second sensor, and the smart chip box can use this to determine the turning angle of the quenching car at this time; the present invention designs a transmission mechanism, and the servo motor actively outputs torque according to the electrical signal of the smart chip box, drives the fourth bevel gear to rotate, and compensates and adjusts the rotation speed of the second connecting rod, so that the differential speed between the first connecting rod and the second connecting rod meets the optimal speed for adapting the turning angle at this time, avoiding the differential speed between the first connecting rod and the second connecting rod. The mismatch causes the wheelset to derail; the present invention designs a shock absorbing mechanism, and by comprehensively analyzing the difference in the pulling of several groups of second cylinders, the angle of the ball head rod offset can be effectively obtained, and then the direction of the heavy weight area can be determined, and the speed of change of the pressure value of the pressure sensor can be used to calculate the weight distribution difference inside the box body, and the adjustable oil valve reduces the oil volume to increase the rebound damping at the corresponding position, so that the object can recover to a stable state more quickly after being subjected to external impact, thereby reducing the amplitude and duration of vibration, and avoiding the quenching car from rolling over due to excessive amplitude in heavy-bearing areas; the present invention detects the turning angle of the quenching car, intelligently determines the differential ratio of the inner and outer wheelsets and actively compensates, ensures the balance and stability of the quenching car when turning, analyzes the load distribution of the quenching car itself, adjusts the damping rebound degree arranged at each point, avoids excessive deviation caused by uneven weight distribution when the quenching car vibrates, and eliminates the hidden danger of the quenching car rolling over.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the present invention provides a technical solution of an intelligent coke quenching car bogie with a balancing and stabilizing function, including a frame 1, a wheelset 2, an intelligent chip box 3, a synchronization mechanism 4, a braking mechanism 5 and a shock absorbing mechanism 6, the frame 1 is rotatably connected to the wheelset 2, the synchronization mechanism 4 includes a connecting frame 41, a synchronous motor 42, a transmission mechanism 43 and a detection mechanism 44, the transmission mechanism 43 includes a servo motor 439, the braking mechanism 5 includes a side frame 51, a first cylinder 52 and a brake disc 55, the shock absorbing mechanism 6 includes a bridge frame 61, the intelligent chip box 3 and the side frame 51 are fixedly connected to the frame 1, the detection mechanism 44 includes a shell 441, a first sensor 443 and a second sensor 446, the brake disc 55 is fixedly connected to the wheelset 2 and the shell 441, the connecting frame 41 and the synchronous motor 42 are fixedly connected to the bridge frame 61, and the intelligent chip box 3 is connected to the synchronous motor 42, the servo motor 439, the first sensor 443, the second sensor 446, and the first cylinder 52 through electrical signals.

[0033] The present invention is an intelligent traveling assembly bogie for a coke quenching car. The coke quenching car itself is a special vehicle for supporting large coke ovens with large mass and volume. When walking on the rails and turning, it is necessary to maintain a precise differential between the inner and outer wheels 2 to ensure smooth turning. The synchronous motor 42 outputs torque to the transmission mechanism 43 to drive the wheels 2 on both sides to walk on the rails. The detection mechanisms 44 on both sides, the brake disc 55 and the wheels 2 are connected through the transmission mechanism 43. When the coke quenching car turns on the rails, the first sensor 443 and the second sensor 446 detect the posture change of the coke quenching car and send an electrical signal to the intelligent The intelligent chip box 3 can analyze the steering angle and acceleration of the quenching car at this time, and determine the most suitable accurate differential speed of the wheel pairs 2 on both sides. When there is a differential speed between the wheel pairs 2 on both sides due to the rolling friction with the rails, the servo motor 439 actively adjusts and compensates the differential speed between the wheel pairs 2 on both sides according to the electrical signal of the intelligent chip box 3 to make it adapt, so as to ensure the balance and stability of the quenching car when turning. The load distribution of the quenching car itself is analyzed through the shock absorbing mechanism 6, and the degree of damping rebound arranged at each point is adjusted to avoid excessive deviation caused by uneven weight distribution when the quenching car vibrates, thereby eliminating the hidden danger of rollover of the quenching car.

[0034] like Figure 2 , Figure 3 As shown, the synchronization mechanism 4 also includes a bevel gear head 45, a first connecting rod 46 and a second connecting rod 47, the detection mechanism 44 is provided with two groups, and the two groups of detection mechanisms 44 are arranged on both sides of the transmission mechanism 43, the outer shell 441 is fixedly connected to the first connecting rod 46 and the second connecting rod 47, the transmission mechanism 43 also includes a drum shell 431 and a bevel gear disk 433, the drum shell 431 is fixedly connected to the connecting frame 41, and the drum shell 431 is provided with a first through hole 4311, a second through hole 4312 and a side hole 4313, the first connecting rod 46 is rotatably connected to the first through hole 4311, and the second through hole 4312 is rotatably connected to the second connecting rod 47, the output end of the synchronous motor 42 is fixedly connected to the bevel gear head 45, the bevel gear head 45 is rotatably connected to the side hole 4313, and the bevel gear head 45 is meshed with the tooth surface of the bevel gear disk 433.

[0035] When traveling in a straight line, the synchronous motor 42 outputs torque to the bevel gear head 45, and the bevel gear head 45 rotates in the side hole 4313. The torque is transmitted through the meshing of the tooth surfaces of the bevel gear head 45 and the bevel gear disc 433. The bevel gear disc 433 drives the first connecting rod 46 to rotate in the first through hole 4311, and the second connecting rod 47 to rotate in the second through hole 4312, thereby driving the wheelsets 2 on both sides to drive synchronously. When the first sensor 443 and the second sensor 446 detect that the quenching car is stalled or overspeeding due to load or slippage between the wheelset 2 and the rail, the synchronous motor 42 intelligently adjusts the output torque and reduces the rotation speed to ensure the stable driving of the quenching car.

[0036] like Figure 3 As shown, the transmission mechanism 43 also includes a chassis 432, a first bevel gear 434, a second bevel gear 435, a third bevel gear 436, a fourth bevel gear 437, and a spring seat 438. The chassis 432 is fixedly connected to the first connecting rod 46 and the bevel gear plate 433. The bevel gear plate 433 is provided with an assembly hole 4331. The assembly hole 4331 and the spring seat 438 are provided with two groups. The two groups of assembly holes 4331 are rotatably connected to the spring seat 438. The first bevel gear 434 is meshed with the third bevel gear 436 and the fourth bevel gear 437. The third bevel gear 436 and the fourth bevel gear 437 are fixedly connected to the spring seat 438. The second bevel gear 435 is meshed with the third bevel gear 436 and the fourth bevel gear 437. The second bevel gear 435 is fixedly connected to the second connecting rod 47.

[0037] When driving in a straight line, the torque is transmitted through the meshing of the tooth surfaces of the bevel gear head 45 and the bevel gear disc 433. The bevel gear disc 433 drives the first connecting rod 46 to rotate in the first through hole 4311 through the assembly chassis 432. The bevel gear disc 433 drives the third bevel gear 436 and the fourth bevel gear 437 to revolve around the axis of the second bevel gear 435 through the assembly hole 4331. Due to the friction between the third bevel gear 436, the fourth bevel gear 437 and the second bevel gear 435, the second bevel gear 435 is driven to rotate around its own axis to make the second connecting rod 47 rotate in the second through hole 4312. When turning, the inner side of the turning angle is assumed to be the second connecting rod 47, and the friction of the rail is relieved by the wheelset 2 on the inner side of the turning angle. In order to make the quenching car turn smoothly, a differential speed is required between the inner and outer sides at this time. The second connecting rod 47 drives the second bevel gear 435 to rotate, and the tooth surface of the second bevel gear 435 meshes with the third bevel gear. 436, the fourth bevel gear 437, the third bevel gear 436, the fourth bevel gear 437 tooth surface meshing with the first bevel gear 434, so that the third bevel gear 436, the fourth bevel gear 437 rotates around its axis in the assembly hole 4331, the third bevel gear 436 and the fourth bevel gear 437 rotate in opposite directions with the same speed, the first bevel gear 434 rotates on the chassis 432, at this time the first connecting rod 46 still transmits torque through the bevel gear plate 433 and the chassis 432, there is a differential between the first connecting rod 46 and the second connecting rod 47, the servo motor 439 actively outputs torque according to the electrical signal of the smart chip box 3, drives the fourth bevel gear 437 to rotate, and the tooth surface of the fourth bevel gear 437 rotates to mesh with the second bevel gear 435, compensates and adjusts the speed of the second connecting rod 47, so that the differential between the first connecting rod 46 and the second connecting rod 47 meets the optimal speed for the turning angle adaptation at this time.

[0038] like Figure 4 As shown, the detection mechanism 44 also includes an arc frame 442, a first inner ring 444, a second inner ring 445, an assembly frame 447, a first motor 448 and a bearing flywheel 449, the arc frame 442 is rotatably connected to the outer shell 441, the first sensor 443 is fixedly connected to the arc frame 442, the first inner ring 444 is rotatably connected to the arc frame 442, the first sensor 443 and the second inner ring 445, the second sensor 446 is fixedly connected to the first inner ring 444, the second inner ring 445 is rotatably connected to the second sensor 446, the assembly frame 447 is fixedly connected to the second inner ring 445 and the first motor 448, and the output end of the first motor 448 is fixedly connected to the bearing flywheel 449.

[0039] Before the quenching car moves, the first motor 448 outputs an initial torque to the bearing flywheel 449, so that the bearing flywheel 449 starts to rotate at a high speed. In the absence of an external force, the angular velocity and direction of the bearing flywheel 449 remain unchanged, and it has a tendency to resist direction change. Inside it, the first inner ring 444 can rotate around the arc frame 442, and the second inner ring 445 rotates around the first inner ring 444, forming a three-dimensional coordinate system inside. When the quenching car turns or accelerates, the arc frame 442 will rotate with the quenching car. When the bearing flywheel 449 receives an external torque, the momentum moment vector of the bearing flywheel 449 will catch up with the external torque at the minimum speed, so that the bearing flywheel 449 moves in the direction of the external torque along the axial direction where the angular momentum is located. The bearing flywheel 449 drives the first inner ring 444 and the second inner ring 445 to deflect. This rotation can be detected by the first sensor 443 and the second sensor 446, and an electrical signal is sent to the smart chip box 3, thereby determining the acceleration state and turning angle of the quenching car.

[0040] like Figure 5 As shown, the brake mechanism 5 also includes an articulated frame 53 and a spring caliper 54. The first cylinder 52 and the articulated frame 53 are fixedly connected to the side frame 51. The output end of the first cylinder 52 is fixedly connected to the spring caliper 54. The spring caliper 54 is hinged to the articulated frame 53, and the spring caliper 54 is in contact with the brake disc 55.

[0041] The quenching car completes braking through the braking mechanism 5 set in the unit, and the brake disc 55 is fixedly assembled on the wheel set 2. When braking is needed, the output end of the first cylinder 52 pushes the spring caliper 54 to engage on the articulated frame 53, and the spring caliper 54 engages and contacts the brake disc 55, and the kinetic energy of the brake disc 55 is converted into the internal energy of the spring caliper 54 and the brake disc 55 through friction, thereby achieving the braking effect.

[0042] like Figure 6 , Figure 7 , Figure 8 As shown, the shock absorbing mechanism 6 also includes a pressure sensing mechanism 62, a support plate 63 and a damping mechanism 64. The pressure sensing mechanism 62 includes a pressure sensor 622, a base 624 and a second cylinder 625. The damping mechanism 64 is provided with a plurality of groups, and the plurality of groups of damping mechanisms 64 are respectively arranged at both ends of the bridge frame 61. The damping mechanism 64 includes an outer oil cylinder 641, an assembly disk 643 and an adjustable oil valve 644. The base 624 and the outer oil cylinder 641 are both fixedly connected to the bridge frame 61, the assembly disk 643 is fixedly connected to the support plate 63, and the pressure sensor 622 and the second cylinder 625 are both connected to the adjustable oil valve 644 through electrical signals.

[0043] The quenching car body is assembled on the pressure sensing mechanism 62 and the support plate 63. The pressure sensor 622 installed on the pressure sensing mechanism 62 identifies the weight distribution in the box body and sends an electrical signal to the adjustable oil valve 644 in the damping mechanism 64 at the corresponding position. In the area with heavy weight, the adjustable oil valve 644 increases the rebound damping of the damping mechanism 64 at the corresponding position. Increasing the rebound damping can more effectively absorb and consume vibration energy, so that the object can recover to a stable state more quickly after being subjected to external impact, thereby reducing the amplitude and duration of vibration, and avoiding the quenching car from overturning due to excessive amplitude in the area with heavy load.

[0044] like Figure 7 As shown, the pressure sensing mechanism 62 also includes a pressure plate 621 and a ball head rod 623, the pressure sensor 622 is fixedly connected to the pressure plate 621 and the ball head rod 623, a first hinge buckle 6211 is provided on the pressure plate 621, a ball cavity 6241 and a second hinge buckle 6242 are provided on the base 624, the first hinge buckle 6211, the second hinge buckle 6242 and the second cylinder 625 are each provided with several groups, several groups of first hinge buckles 6211 are evenly distributed along the circumference of the pressure plate 621, several groups of second hinge buckles 6242 and second cylinders 625 are evenly distributed along the circumference of the base 624, the ball head rod 623 is in contact with the ball cavity 6241, and the second cylinder 625 is hinged to the first hinge buckle 6211 and the second hinge buckle 6242.

[0045] The quenching car body is assembled on the pressure plate 621. After the material is loaded into the box, the weight is not evenly distributed inside the box, and the pressure plate 621 shifts to the area with heavy weight. At this time, the ball head rod 623 rotates in the ball cavity 6241, and the pressure value recorded by the pressure sensor 622 is changing. Several groups of second cylinders 625 evenly distributed along the circumference of the base 624 are all pulled. By combining the difference in the pulling of several groups of second cylinders 625, the offset angle of the ball head rod 623 can be effectively obtained, and then the direction of the heavy weight area can be determined. Through the speed of the change of the pressure value of the pressure sensor 622 and the offset angle of the ball head rod 623, the difference between the heavy weight area and the light weight area inside the box can be finally calculated. The difference ultimately determines the rebound damping that needs to be increased by the damping mechanism 64.

[0046] like Figure 8 As shown, the damping mechanism 64 also includes an inner oil cylinder 642, an outer spring 645 and a piston rod 646. The outer oil cylinder 641 is provided with a first sliding hole 6411, and the inner oil cylinder 642 is provided with a second sliding hole 6421. The piston rod 646 is fixedly connected to the assembly disk 643 and the adjustable oil valve 644. The piston rod 646 is slidably connected to the first sliding hole 6411 and the second sliding hole 6421. The inner oil cylinder 642 is slidably connected to the outer oil cylinder 641, and the outer spring 645 is fixedly connected to the assembly disk 643 and the outer oil cylinder 641.

[0047] The support plate 63 distributes the weight on each group of damping mechanisms 64. When the quenching car vibrates, the support plate 63 squeezes the outer spring 645 and converts the kinetic energy of the vibration into the internal energy of the outer spring 645. When the outer spring 645 recovers its deformation, it pulls the piston rod 646 to slide in the inner oil cylinder 642 toward the support plate 63. The hydraulic oil in the inner oil cylinder 642 passes through the adjustable oil valve 644, and the inner oil cylinder 642 slides in the outer oil cylinder 641. The resistance of the hydraulic oil converts the kinetic energy of the outer spring 645 recovering its deformation into the internal energy of the hydraulic oil. When it is necessary to increase the rebound damping, the adjustable oil valve 644 reduces the amount of oil passing through, and the flow speed of the liquid slows down, thereby increasing the flow resistance and increasing the damping.

[0048] The working principle of the present invention is as follows: the synchronous motor 42 outputs torque to drive the wheel pairs 2 on both sides to walk on the rails. When turning, the arc frame 442 will rotate with the quenching car. When the bearing flywheel 449 receives the external torque, the momentum moment vector of the bearing flywheel 449 will catch up with the external torque at the minimum speed, so that the bearing flywheel 449 moves in the direction of the external torque along the axial direction where the angular momentum is located. The bearing flywheel 449 drives the first inner ring 444 and the second inner ring 445 to deflect, and sends an electrical signal to the smart chip box 3 through the first sensor 443 and the second sensor 446. The smart chip box 3 analyzes the steering angle of the quenching car at this time and determines the most suitable accurate differential of the wheel pairs 2 on both sides. When turning, the inner side of the turning angle is assumed to be the second connecting rod 47, and the friction of the rail is relieved by the wheel pair 2 on the inner side of the turning angle. In order to make the quenching car turn smoothly, there is a passive differential between the inner and outer sides at this time. The second connecting rod 47 drives the second bevel gear 435 to rotate. The tooth surface of 435 meshes with the third bevel gear 436 and the fourth bevel gear 437. The third bevel gear 436 and the fourth bevel gear 437 rotate on their own and turn in opposite directions at the same speed. At this time, the first connecting rod 46 still transmits torque through the bevel gear plate 433 and the chassis 432. There is a differential between the first connecting rod 46 and the second connecting rod 47. The servo motor 439 actively outputs torque according to the electrical signal of the intelligent chip box 3, drives the fourth bevel gear 437 to rotate, and meshes the second bevel gear 435 through the rotating tooth surface of the fourth bevel gear 437, and compensates and adjusts the speed of the second connecting rod 47, so that the differential speed between the first connecting rod 46 and the second connecting rod 47 meets the optimal speed for the turning angle at this time, ensuring the balance and stability of the coke quenching car when turning, analyzing the load distribution of the coke quenching car itself through the shock absorbing mechanism 6, adjusting the degree of damping rebound arranged at various points, avoiding excessive deviation caused by uneven weight distribution when the coke quenching car vibrates, and eliminating the hidden danger of rollover of the coke quenching car.
