Description

Technical Field

[0001] This application relates to the field of coke pushing equipment technology, and in particular to a coke pushing equipment travel speed control device. Background Technology

[0002] Coke pushers are widely used in various automated production lines, especially in applications requiring material conveying, position control, and rhythm adjustment, such as steel smelting and coal processing. These devices are typically used to push or pull heavy objects, ensuring a constant flow of material throughout the production process. In coke pushers, travel speed control is a crucial element in ensuring smooth and precise operation. Controlling the travel speed directly impacts production efficiency, as well as equipment lifespan, safety, and energy consumption.

[0003] Existing coke pushing equipment mainly controls its speed by controlling the friction between the friction plates and wheels in the hydraulic braking system. This ensures that the equipment can quickly and accurately reach the designated pushing position. While controlling the friction between the friction plates and wheels can control the equipment's speed, this method only works when the equipment is moving too fast. When the friction between the wheels and the travel rails is too high, causing the equipment to move too slowly, this method no longer meets the requirement for stable speed control. As a result, the equipment may fail to reach the designated position within the specified time when the speed is too slow. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a coking equipment travel speed control device that can ensure the stability of the coking equipment travel speed by friction braking when the coking equipment travels too fast, and can also ensure the stability of the coking equipment travel speed by assisting propulsion when the coking equipment travels too slow.

[0005] The above-mentioned objective of this application is achieved through the following technical solution:

[0006] A coke pushing equipment travel speed control device includes a coke pushing car frame. A support plate is welded to each of the four corners of the bottom end of the coke pushing car frame. A drive mechanism is installed on the lower part of each support plate. The drive mechanism includes a motor and wheels. A friction speed limiting mechanism is installed between two support plates on the same side of the coke pushing car frame. The friction speed limiting mechanism includes a motor, a fixed plate, a screw, a screw sleeve, a linkage plate, and friction columns. The fixed plate is installed between the two support plates on the same side. The motor is located at the middle of the top end of each support plate. The screw is connected to the motor. The screw sleeve is connected to the lower side of the screw. The middle of the top end of the linkage plate is connected to the bottom end of the screw sleeve. There are two friction columns. The friction columns are symmetrically installed on both sides of the bottom end of the linkage plate. An inverted L-shaped mounting plate is also welded to the support plate on the side of the wheel. A hanging plate is welded to the upper side wall of the mounting plate. An assist mechanism is installed on the lower side of the hanging plate. The assist mechanism includes an electric telescopic rod, a connecting frame, an assist wheel, a second motor, and a transmission box. There are two electric telescopic rods, which are symmetrically installed on both sides of the bottom end of the hanging plate. The telescopic parts of the two electric telescopic rods are connected to the connecting frame. The assist wheel is rotatably mounted on the connecting frame. The transmission box is installed on one side wall of the connecting frame, directly opposite the axle of the assist wheel. The second motor is installed at the power input end of the transmission box.

[0007] Optionally, there are no fewer than three booster wheels, and a sprocket is also installed in the transmission box at the axle of each booster wheel, with a chain sleeved on the outside of the sprocket.

[0008] Optionally, the motor is connected to the axle coupling of one of the booster wheels, and the chain engages with the sprocket.

[0009] Optionally, the connecting frame has an inverted U-shaped structure, and the bottom end of the assist wheel is lower than the bottom end of the connecting frame.

[0010] Optionally, the motor is connected to the screw coupling, the screw is threadedly connected to the screw sleeve, and the screw sleeve is welded to the linkage plate.

[0013] Optionally, the motor is bolted to the lower part of the outer wall of the support plate, the wheel is rotatably mounted on the inner side of the support plate, and the wheel is connected to the motor via a coupling.

[0014] Optionally, a Hall effect speed sensor is also installed on the inner side of the support plate at each of the wheels.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] This invention utilizes a friction speed limiting mechanism, consisting of a motor, a fixed plate, a screw, a screw sleeve, a linkage plate, and a friction column, installed between two support plates on the same side. When the coke pusher car frame travels too fast, the motor drives the screw to rotate, causing the screw sleeve, linkage plate, and friction column to move downwards. This allows the friction column to contact and rub against the foundation beside the coke pusher car frame's travel track, thereby reducing the coke pusher car frame's travel speed and ensuring it remains within a specified speed range. Simultaneously, by installing an assist mechanism consisting of an electric telescopic rod, a connecting frame, an assist wheel, a motor, and a transmission box beside each wheel, when the coke pusher car frame travels at a slower speed, the rotating assist wheel contacts the foundation beside the coke pusher car frame's travel track, thus assisting the coke pusher car frame's movement and ensuring it reaches the designated coke pushing position within a specified time.

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] To better understand the technical solutions presented in the embodiments of this application, the control principle of the travel speed of existing coke pushing equipment will be introduced first.

[0024] Existing coke pushing equipment mainly controls the speed of the equipment by controlling the friction force between the friction plates and the wheels in the hydraulic braking system. This ensures the stability of the equipment's speed and allows it to quickly and accurately reach the designated coke pushing position within a specified time.

[0025] Please see Figure 1 , Figure 2 and Figure 4 This application discloses a coking equipment travel speed control device, including a coking car frame 1. A support plate 8 is welded to each of the four corners of the bottom end of the coking car frame 1. A drive mechanism 6 is installed on the lower part of the support plate 8. The drive mechanism 6 includes a motor 62 and wheels 61. A friction speed limiting mechanism 7 is installed between two support plates 8 on the same side of the lower side of the coking car frame 1. The friction speed limiting mechanism 7 includes a motor 71, a fixing plate 72, a screw 73, a screw sleeve 74, a linkage plate 75, and a friction column 76. The fixing plate 72 is installed between the two support plates 8 on the same side. The motor 71 is located at the middle of the top of the support plate 8. The screw 73 is connected to the motor 71. The screw sleeve 74 is connected to the lower side of the screw 73. The middle of the top of the linkage plate 75 is connected to the bottom of the screw sleeve 74. The friction column... There are two friction columns 76, and the two friction columns 76 are symmetrically installed on both sides of the bottom end of the linkage plate 75. An inverted L-shaped mounting plate 3 is also welded on the support plate 8 on the side of the wheel 61. A hanging plate 2 is welded to the upper side wall of the mounting plate 3. An assist mechanism 5 is installed on the lower side of the hanging plate 2. The assist mechanism 5 includes an electric telescopic rod 51, a connecting frame 52, an assist wheel 53, a second motor 54, and a transmission box 55. There are two electric telescopic rods 51, which are symmetrically installed on both sides of the bottom end of the hanging plate 2. The telescopic parts of the two electric telescopic rods 51 are connected to the connecting frame 52. The connecting frame 52 is rotatably mounted with the assist wheel 53. The transmission box 55 is installed on one side wall of the connecting frame 52, directly opposite the axle of the assist wheel 53. The second motor 54 is installed at the power input end of the transmission box 55.

[0026] Specifically, when the coke pusher car frame 1 travels too fast, the screw 73 is rotated by the motor 71, causing the screw sleeve 74, the linkage plate 75, and the friction column 76 to move downwards. This allows the friction column 76 to contact and rub against the foundation beside the coke pusher car frame 1's travel track, thereby reducing the travel speed of the coke pusher car frame 1 and ensuring that the travel speed of the coke pusher car is maintained within the specified speed range. When the coke pusher car frame 1 travels at a slower speed, the rotating assist wheel 53 is made to contact the foundation beside the coke pusher car frame 1's travel track by the electric telescopic rod 51, thereby assisting the movement of the coke pusher car frame 1 and ensuring the stability of the coke pusher car frame's travel speed.

[0027] Please see Figure 1 and Figure 3There are at least three booster wheels 53, and a sprocket 551 is installed in the transmission box 55 at the axle of each booster wheel 53. A chain 552 is sleeved on the outside of the sprocket 551.

[0028] In one implementation, the chain 552 and the sprocket 551 work together to achieve synchronous rotation of each assist wheel 53 on the connecting frame 52, so as to achieve assisted movement of the coke pusher frame 1 under the action of the assist wheel 53.

[0029] Please see Figure 1 and Figure 3 The motor 62 is connected to the axle coupling of one of the booster wheels 53, and the chain 552 engages with the sprocket 551.

[0030] In one implementation, after the motor 62 is started, it will drive the corresponding axle of the booster wheel 53 to rotate. When one of the booster wheels 53 rotates, the axles of the other booster wheels 53 will rotate synchronously under the action of the chain 552 and the sprocket 551.

[0031] Please see Figure 1 The connecting frame 52 has an inverted U-shaped structure, and the bottom of the assist wheel 53 is lower than the bottom of the connecting frame 52.

[0032] As one implementation method, making the bottom of the assist wheel 53 lower than the bottom of the connecting frame 52 can help the vehicle descend during movement and ensure that the bottom of the assist wheel 53 can reliably contact the foundation next to the travel track of the coke pusher frame 1.

[0033] Please see Figure 1 and Figure 2 Motor 71 is connected to screw 73 by a coupling, screw 73 is connected to screw sleeve 74 by a thread, and screw sleeve 74 is welded to linkage plate 75.

[0034] As one implementation method, welding the screw sleeve 74 to the linkage plate 75 can ensure that the linkage plate 75 is synchronously raised and lowered with the screw sleeve 74 during the rotation of the screw 73.

[0035] Please see Figure 1 , Figure 2 and Figure 4 The linkage plate 75 has a slide table reserved at both ends, and the support plate 8 has a slide groove reserved at the part that mates with the slide table of the linkage plate 75.

[0036] As one implementation method, the slide table on the linkage plate 75 cooperates with the reserved slide groove on the support plate 8 to ensure the smooth lifting and lowering of the linkage plate 75 during the lifting and lowering adjustment process.

[0037] Please see the figure and Figure 2 The friction column 76 is bonded to the linkage plate 75, and the friction column 76 is a rubber rod.

[0038] As one implementation method, the friction column 76 has a certain length. When the friction column 76 contacts the foundation next to the coke pusher car foot travel track, the bottom end of the linkage plate 75 does not slide off the support plate 8, and the screw sleeve 74 still cooperates with the screw sleeve 74, so as to ensure the convenient upward movement of the friction column 76 after the friction braking speed limit.

[0039] Please see Figure 1 Motor 62 is bolted to the lower part of the outer wall of support plate 8, and wheel 61 is rotatably mounted on the inner side of support plate 8, and wheel 61 is connected to motor 62 by coupling.

[0040] In one implementation, motor 62 is a geared motor. Motor 62 drives wheel 61 to rotate, which can ensure the convenient movement of coke pusher car frame 1 and realize the adjustment of the position of coke pusher car frame 1.

[0041] Please see Figure 1 A Hall effect speed sensor 4 is also installed on the inner side of the support plate 8 at each wheel 61.

[0042] As one implementation method, the speed sensor 4 is mainly used to measure the wheel speed of the wheel 61 so that the processing components on the coking equipment can detect the actual travel speed of the coking car frame 1 and determine whether the coking car frame 1 is too fast or too slow. When the speed of the coking car frame 1 is abnormal, the friction speed limiting mechanism 7 and the assist mechanism 5 are activated as needed by the control system on the coking equipment.

[0043] The specific working principle is as follows: First, the speed control device is connected to the control system on the coke pushing equipment. Then, under the action of motor 62, the wheels 61 rotate, allowing the coke pushing car frame 1 to move. During the movement of the coke pushing car frame 1, the speed sensor 4 can measure the travel speed of the coke pushing car frame 1 in real time and feed the speed information back to the control system of the coke pushing equipment. When the travel speed of the coke pushing car frame 1 is too fast, motor 71 drives the screw 73 to rotate, thereby causing the screw sleeve 74 and the linkage plate to move. 75 and friction column 76 move down so that friction column 76 comes into contact with the foundation next to the coke pusher car frame 1 travel track, thereby reducing the travel speed of the coke pusher car frame 1 and ensuring that the travel speed of the coke pusher car is maintained within the specified speed range. At the same time, when the travel speed of the coke pusher car frame 1 is slow, the electric telescopic rod 51 causes the rotating assist wheel 53 to move down and come into contact with the foundation next to the coke pusher car frame 1 travel track, thereby achieving assisted movement of the coke pusher car frame 1 and ensuring that the coke pusher car frame 1 can reach the specified coke push position within the specified time.

[0044] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
