Description

Technical Field

[0001] This utility model relates to the technical field of coke oven quenching cars, and in particular to a door locking device and a coke quenching car. Background Technology

[0002] Wet quenching is a common quenching method in the coking industry. After the coking process, the red-hot coke exiting the coke oven reaches a temperature of approximately 1000℃, requiring cooling. Wet quenching utilizes the intense heat exchange between water and the red-hot coke to rapidly cool it, meeting the requirements for subsequent transportation, storage, and use. In this process, the quenching car is used to carry the red-hot coke from the coke oven and transport it to the quenching tower for the quenching operation. It typically consists of a car body, a traveling mechanism, and a door opening mechanism.

[0003] However, in the current wet quenching process of coke ovens, the opening mechanism of the quenching car is at risk of being blown open by the water flowing from the high-level water tank. The water flowing from the high-level water tank has a certain impact force. When this impact force acts on the opening mechanism of the car door, it can easily cause the quenching car door to open unexpectedly, resulting in a large amount of coke spilling and accumulating inside the quenching tower. This not only severely restricts normal production but also requires manual handling using a trolley for unloading and cleaning, posing a significant safety risk. Utility Model Content

[0004] The purpose of this utility model is to provide a door locking device and a coke quenching car to solve the technical problem that the doors of the existing coke quenching cars lack a locking structure and are easily opened accidentally.

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] See Figure 1 The door locking device provided in this embodiment includes a locking rod 1 and a drive assembly 2. The locking rod 1 has a limiting groove 11, which faces the locking shaft of the door. The locking rod 1 can move relative to the locking shaft, allowing the limiting groove 11 to move closer to or further away from the locking shaft. When the limiting groove 11 is engaged with the locking shaft, the door is locked; when the limiting groove 11 is away from the locking shaft, the door is unlocked. The drive assembly 2 includes a drive unit 21 and a transmission structure 22. The output end of the drive unit 21 is connected to the transmission structure 22, which is connected to the locking rod 1. The drive unit 21 can control the movement of the locking rod 1 relative to the locking shaft through the transmission structure 22.

[0030] The door locking device proposed in this utility model, on the one hand, uses a locking rod 1 with a limiting groove 11 adapted to the door locking shaft. When the limiting groove 11 engages with the locking shaft, the door is locked, effectively preventing accidental opening and enhancing the stability of the door during operation. On the other hand, the drive assembly 2 realizes automated control of the movement of the locking rod 1. The operator can control the locking rod 1 from a safe position via the drive unit 21 and the transmission structure 22. The movement of the locking rod 1 relative to the locking shaft switches the door between locked and unlocked states, avoiding the risk of close contact with high-temperature coke and improving operational convenience and safety. In summary, this device, through the coordinated operation of the locking rod 1 and the drive assembly 2, realizes the door locking and control functions, improves the stability of the door during use, avoids the risk of accidental opening, and enhances the safety of the operation process.

[0031] The specific structure of the door locking device is described below.

[0032] Because the coke quenching car has high temperatures inside during operation, in order to prevent the high temperature from directly contacting the electrical equipment such as the drive unit 21 and causing damage to the equipment, the drive unit 21 controls the locking rod 1 through the transmission structure 22.

[0033] Specifically, the transmission structure 22 includes a central rotating rod 221, with a first rotating shaft 223 located in the middle of the central rotating rod 221. The central rotating rod 221 can rotate around the first rotating shaft 223. One end of the central rotating rod 221 is connected to the output end of the drive unit 21, and the other end is connected to the locking rod 1. The central rotating rod 221 and the first rotating shaft 223 form a lever-type transmission structure 22, which can change the direction and magnitude of the force. The force output by the drive unit 21 is input through one end of the central rotating rod 221. During rotation around the first rotating shaft 223, it can be transmitted to the locking rod 1 in different forms at the other end of the central rotating rod 221, achieving more flexible and precise control over the movement of the locking rod 1. For example, when the drive unit 21 outputs a smaller force, the lever principle of the central rotating rod 221 can generate a force sufficient to push the locking rod 1, effectively improving the transmission efficiency of the drive assembly 2.

[0034] Preferably, the transmission structure 22 further includes a transmission rod 222, one end of which is detachably connected to the other end of the transfer rod 221, and the other end of which is detachably connected to the locking rod 1. The transmission rod 222 serves as an extension and adjustment mechanism between the transfer rod 221 and the locking rod 1. The transmission rod 222 can flexibly adjust the distance between the transfer rod 221 and the locking rod 1 according to the actual installation space and layout requirements, allowing the entire transmission structure 22 to be rationally laid out in different equipment space environments, thus enhancing the versatility and adaptability of the door locking device. Furthermore, the transmission rod 222 can more stably and efficiently transmit the power from the transfer rod 221 to the locking rod 1, reducing power loss during transmission.

[0035] Preferably, the drive unit 21 is a telescopic motor, and the telescopic end of the telescopic motor is connected to one end of the central rotating rod 221. The telescopic motor can precisely adjust the output displacement, thereby accurately controlling the rotation amplitude of the central rotating rod 221, and thus precisely controlling the movement position of the locking rod 1 relative to the locking shaft, realizing precise switching between the locked and unlocked states of the door, and improving the accuracy of door control.

[0036] Furthermore, the transfer rod 221 includes a first rod segment 2211 and a second rod segment 2212, which are integrally formed and set at a first included angle 224. A first rotating shaft 223 is disposed at the connection between the first rod segment 2211 and the second rod segment 2212. The first rod segment 2211 is connected to the locking rod 1, and the second rod segment 2212 is connected to the drive unit 21. The first rod segment 2211 and the second rod segment 2212, set at the first included angle 224, optimize the force transmission path. When the force exerted by the drive unit 21 on the second rod segment 2212 is transmitted to the first rod segment 2211 and then to the locking rod 1 through the structure at the first included angle 224, the power of the drive unit 21 can be converted into a force that pushes the locking rod 1 more effectively than a straight transfer rod 221, thus enhancing the transmission efficiency of the device. Moreover, the non-linear structure of the transfer rod 221 can better adapt to the positional distribution of different equipment components. For example, it can avoid interference from other equipment, make reasonable use of irregular spaces, and allow the door locking device to be installed more compactly and cleverly in a suitable position, thereby improving the overall space utilization of the equipment.

[0037] Preferably, the length of the second rod segment 2212 is greater than the length of the first rod segment 2211. Based on the lever principle, with the first pivot 223 as the fulcrum, the second rod segment 2212 connects to the drive unit 21, and its longer length forms a larger lever arm. When the drive unit 21 applies a certain force, the longer lever arm enables the drive unit 21 to generate a larger torque. This means that under the same driving force, it is easier to drive the first rod segment 2211 and the locking rod 1 connected to it to move, realizing the locking or unlocking action of the door, reducing the output force requirement of the drive unit 21, improving energy utilization efficiency, and even if the output force of the drive unit 21 is relatively small, it can effectively drive the locking rod 1, ensuring the normal operation of the door control device.

[0038] Preferably, the first included angle 224 has a degree greater than or equal to 120 degrees and less than or equal to 150 degrees. In this embodiment, the first included angle 224 is set to 120 degrees. In other embodiments, the first included angle 224 may also be set to 125 degrees, 130 degrees, 135 degrees, 140 degrees, 145 degrees, etc., which are not limited here.

[0039] The power output from the drive unit 21 is transmitted to the locking rod 1 through the transfer rod 221 and the transmission rod 222. By controlling the movement of the locking rod 1, the locking and unlocking process of the car door is realized. Specifically, the locking rod 1 includes a third rod segment 12 and a fourth rod segment 13. The third rod segment 12 and the fourth rod segment 13 are integrally formed and set at a second included angle 15. The integrally formed locking rod 1 reduces the possible weak points in the connection part, reduces the risk of damage caused by stress concentration, enables the locking rod 1 to withstand greater external forces, and extends the service life of the locking rod 1. A second rotating shaft 14 is provided at the connection between the third rod segment 12 and the fourth rod segment 13. The locking rod 1 can rotate around the second rotating shaft 14. A limit groove 11 is provided on the third rod segment 12, and the fourth rod segment 13 is connected to the transmission structure 22. When the transmission structure 22 drives the fourth rod segment 13 to move, the third rod segment 12 can rotate around the second rotating shaft 14 as the center to adjust the relative position of the limiting groove 11 and the door locking shaft. Compared with the single-structure locking rod 1, it can more accurately and smoothly realize the locking and disengaging action of the limiting groove 11 on the locking shaft, effectively improving the accuracy and reliability of the door locking and unlocking operation.

[0040] Preferably, the second included angle 15 is greater than or equal to 90 degrees and less than or equal to 120 degrees. In this embodiment, the second included angle 15 is set to 110 degrees. In other embodiments, the second included angle 15 can be 90 degrees, 110 degrees, etc., and is not limited here.

[0041] In this embodiment, the limiting groove 11 is semi-circular. The semi-circular limiting groove 11 can achieve a good fit with the circular locking shaft, maximizing the contact area between the two, thereby more evenly distributing the forces from the door and the external environment, and avoiding wear or damage caused by excessive local force. In addition, the semi-circular limiting groove 11 provides a smoother guide for the locking shaft to enter and exit the limiting groove 11. When the locking lever 1 moves to switch the door state, the locking shaft can slide into or out of the semi-circular limiting groove 11 more smoothly, reducing jamming and making the locking and unlocking operation of the door easier and smoother.

[0042] In other embodiments, the locking groove may also be rectangular, trapezoidal, irregular in shape, etc., which will not be elaborated here.

[0043] In addition, a shock-absorbing layer is installed inside the limiting groove 11. During the wet quenching process, the quenching car may be subjected to various vibrations and impacts, such as the impact of water flowing down from the high-level water tank and the bumps during travel. When these external forces are transmitted to the door, causing the locking shaft to interact with the limiting groove 11, the shock-absorbing layer can effectively buffer the impact force between the two, avoiding direct hard collision between the locking shaft and the limiting groove 11. This not only protects the locking shaft and the limiting groove 11 themselves, preventing them from wearing, deforming, or even being damaged due to frequent impacts, thereby extending the service life of the door locking device and reducing equipment maintenance costs, but also reduces the risk of door loosening caused by impacts, ensuring the stability of the door in the locked state and maintaining the normal operation of the production process.

[0044] The damping layer can be made of rubber pads, silicone pads, etc., and there are no restrictions on its use.

[0047] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments.
