Coke oven exchanger drive rod

Abstract

This application discloses a coke oven exchanger drive rod, which is composed of multiple connecting rods connected in sequence. Each connecting rod has threaded posts at both ends. The near ends of every two adjacent connecting rods are connected by a connecting sleeve. Each end of the connecting sleeve has a first insertion hole, and the first insertion hole contains a first threaded connection hole. Support plates are provided on the outer walls of the near ends of every two adjacent connecting rods. Through holes are formed on the support plates for inserting threaded connection posts. Because the rod is composed of multiple connecting rods connected in sequence, if one section of the rod breaks, a spare section can be used to replace the broken section. This improves the maintenance efficiency of the rod compared to replacing the entire rod. The limited length of multiple connecting rods makes transportation easier than a single-piece rod. Furthermore, when expanding the coke oven capacity, the number of rod sections can be increased to extend the transmission rod without the need for custom-made long rods.

Description

Technical Field

[0001] This utility model belongs to the technical field of coke oven control devices, specifically relating to a coke oven switch drive lever. Background Technology

[0002] During normal reversing, the coke oven gas exchanger performs forward and reverse gas exchange and waste gas exchange. The reversing power is provided by a hydraulic cylinder. That is, the reversing process is completed by the hydraulic cylinder pulling the connecting rod device to open and close the flap to realize the forward and reverse exchange of waste gas.

[0003] The problem in practice is that existing air and exhaust gas exchange devices often switch at 30-minute intervals by driving a hydraulic cylinder to pull a rod. During repeated operation, since the rod needs to connect multiple exchanges, the existing rods are made in one piece and are tens or hundreds of meters long. During long-term reciprocating transmission, they are prone to loosening, deformation, and breakage. The long rods made in one piece are also inconvenient to repair and replace. Utility Model Content

[0004] This application proposes a drive rod for a coke oven exchanger, which is formed by connecting multiple connecting rods in sequence. When a section of the rod breaks, a spare section can be used to replace the broken section, which improves the maintenance efficiency of the rod compared to replacing the entire rod.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A coke oven exchanger drive rod is composed of multiple connecting rods connected in sequence. Each connecting rod has a threaded post at both ends. The near ends of each pair of adjacent connecting rods are connected by a connecting sleeve. Each connecting sleeve has a first insertion hole at both ends. The first insertion hole contains a first threaded connection hole. Each pair of adjacent connecting rods has a support plate on its outer wall near the end. The support plate has a through hole for inserting the threaded connection post.

[0007] In one embodiment of this application, a washer is provided in the first insertion hole of the connecting sleeve.

[0008] In one embodiment of this application, the first and last connecting rods, which are connected in sequence, are connected to an installation sleeve at the ends away from the support plate.

[0009] In one embodiment of this application, the end face of the mounting sleeve is provided with a second insertion hole, and a second threaded hole is provided inside the second insertion hole.

[0010] In one embodiment of this application, the end edge of the mounting sleeve is provided with a plurality of connecting plates, and each connecting plate is provided with a connecting hole.

[0011] In one embodiment of this application, the connecting rod is made of Q345 steel.

[0012] In one embodiment of this application, the connecting rod is provided with slots at both ends.

[0013] In summary, the technical solution proposed in this application includes the following beneficial technical effects: This application is composed of multiple connecting rods connected in sequence. When a section of the tie rod breaks, a spare section can be used to replace the broken section. Compared with replacing the tie rod as a whole, this improves the maintenance efficiency of the tie rod. The limited length of multiple connecting rods makes them easier to transport than a one-piece molded rod. Furthermore, when expanding the capacity of the coke oven, the transmission rod can be extended simply by increasing the number of tie rod sections, without the need to re-customize the entire long rod.

[0031] This embodiment provides a drive lever for a coke oven exchanger, see reference. Figures 1-6As shown, the pull rod is composed of multiple connecting rods 1 connected in sequence. Each connecting rod 1 has a threaded post at both ends. The near ends of each pair of adjacent connecting rods 1 are connected by a connecting sleeve 2. Each connecting sleeve 2 has a first insertion hole 21 at both ends. The first insertion hole 21 has a first threaded connection hole 211. Each pair of adjacent connecting rods 1 has a support plate 3 on its outer wall near the end. The support plate 3 has a through hole 31 for inserting the threaded connecting post 4.

[0032] In the above embodiment, the pull rod is composed of multiple connecting rods 1 connected sequentially. Each connecting rod 1 has threaded posts at both ends, and the near ends of every two adjacent connecting rods 1 are connected by a connecting sleeve 2. That is, the connecting sleeve 2 has first insertion holes 21 at both ends. The end edge of the connecting rod 1 is inserted into the first insertion hole 21. Further, the first insertion hole 21 has a first threaded connection hole 211. The threaded post at the end edge of the connecting rod 1 is then screwed into the first threaded connection hole 211 to realize the connection between the ends of two adjacent connecting rods 1 through the engagement of the threaded post at the end edge with the first threaded connection hole 211 in the first insertion hole 21 at both ends of the connecting sleeve 2. Further, a support plate 3 is provided on the outer wall of the near end of each of the two adjacent connecting rods 1. The support plate 3 is connected to the outer wall of the connecting rod 1, and a through hole 31 is opened on the support plate 3. The threaded post on one end of the connecting rod 1 is located at the outer end of the connecting rod 1 compared to the support plate 3. Figure 1 As shown, threaded connecting posts 4 are inserted into the through holes 31 of the support plates 3 on two adjacent connecting rods 1. The threaded connecting posts 4 have threaded portions at both ends, which are inserted into the through holes 31 of the two support plates 3. Figure 5 As shown, the threaded connecting column 4 is fixedly connected to the support plate 3 by a fastening nut, so that the connecting rod 1 is connected through the connecting sleeve 2 and then reconnected through the threaded connecting column 4 and the support plate 3, which helps to improve the stability of the connection of the connecting rod 1. It is composed of multiple connecting rods 1 connected in sequence. When a section of the tie rod breaks, a spare section can be used to replace the broken section. Compared with replacing the tie rod as a whole, the maintenance efficiency of the tie rod is improved. The length of multiple connecting rods 1 is limited, which is more convenient for transportation than a one-piece molded rod. Moreover, when the coke oven is expanded, the transmission rod can be extended by simply increasing the number of tie rod sections, without the need to customize a new long rod.

[0033] In one embodiment of this application, see reference Figure 5 and Figure 6 As shown, a washer 212 is provided in the first insertion hole 21 of the connecting sleeve 2.

[0034] In the above embodiment, the washer 212 provided in the first insertion hole 21 of the connecting sleeve 2 can be a rubber washer 212. When one end of the connecting rod 1 is inserted into the first insertion hole 21, the outer wall of the connecting rod 1 comes into contact with and is squeezed by the rubber soft washer 212, so that the washer 212 fills the gap between the connecting rod 1 and the first insertion hole 21, thereby making the first threaded connection hole 211 in the first insertion hole 21 in a sealed state, preventing external stains, moisture or dust particles from entering the first threaded connection hole 211 through the gap between the connecting rod 1 and the first insertion hole 21, causing the threaded post of the connecting rod 1 to rust. This facilitates the disassembly and assembly of the connecting rod 1 during maintenance. On the other hand, preventing the threaded post of the connecting rod 1 from rusting is beneficial to improving the stability of the pull rod during transmission and improving the stability of the pull rod during transmission.

[0035] In one embodiment of this application, see [reference] Figure 1 As shown, the first connecting rod 1 and the last connecting rod 1 connected in sequence have an installation sleeve 5 connected to the end away from the support plate 3.

[0036] In the above embodiment, the mounting sleeve 5 is located at the end of the connecting rod 1 away from the support plate 3. That is, after the connecting rod 1 is connected to form a drive rod, the mounting sleeve 5 is connected to both ends of the drive rod. The connecting sleeve 2 can be used to connect both ends of the drive rod to the drive chain of the switch. The drive chain has a certain degree of flexibility, that is, the drive chain can be used to change the transmission direction of the drive rod, improve the drive adaptability of the drive rod, and help improve the stability of the switch operation.

[0037] In one embodiment of this application, see reference Figure 3 As shown, the end face of the mounting sleeve 5 is provided with a second insertion hole 51, and a second threaded hole 511 is provided inside the second insertion hole 51.

[0038] In the above embodiment, when the mounting sleeve 5 is connected to the threaded post of the connecting rod 1, the connecting rod 1 is first inserted into the second insertion hole 51, and then the threaded post of the connecting rod 1 is engaged with the second threaded hole 511 in the second insertion hole 51. That is, the threaded engagement is a detachable connection. Compared with directly fixing and welding the mounting sleeve 5 to the connecting rod 1, it is beneficial to improve the convenience of maintenance and replacement of the mounting sleeve 5.

[0039] In one embodiment of this application, see reference Figure 3 As shown, the end edge of the mounting sleeve 5 is provided with a plurality of connecting plates 52, and each connecting plate 52 is provided with a connecting hole.

[0040] In the above embodiment, the end edge of the mounting sleeve 5 is provided with a plurality of connecting plates 52, and each connecting plate 52 is provided with a connecting hole. The plurality of connecting plates 52 can be used to select a suitable connection position to connect with a transmission component such as a transmission chain or a transmission support rod, which is beneficial to improving the connection adaptability of the mounting sleeve 5 and improving the installation connection efficiency of the mounting sleeve 5.

[0041] In one embodiment of this application, the connecting rod 1 is made of Q345 steel.

[0042] In the above embodiments, the tie rod is typically made of Q235 steel. The operating temperature of coke oven tie rods is typically 80–160℃. Q235 steel exhibits a strength decrease of >30% at 150℃, while Q345 steel shows a decrease of <15% at 150℃, meaning Q345 steel has stronger high-temperature stability than Q235 steel. Furthermore, Q235 steel has a tensile strength of 375–500 MPa, while Q345 has a tensile strength of 470–630 MPa. To achieve the same tensile strength, the tie rod made of Q345 steel requires less material than that made of Q235 steel. This reduced material weight decreases the inertia of the transmission system, which is beneficial for reducing the power consumption of the hydraulic cylinder.

[0043] In one embodiment of this application, see reference Figure 2 As shown, the connecting rod 1 has slots 11 at both ends.

[0044] In the above embodiment, slots 11 are provided on the curved outer walls at both ends of the connecting rod 1. On the one hand, this facilitates clamping or binding the connecting rod 1 for transportation, preventing the connecting rod 1 from slipping during transportation. On the other hand, when installing the connecting rod 1, a clamp can be used to clamp the outer wall of the connecting rod 1, which facilitates the installation operation of the connecting rod 1 and helps to improve the installation efficiency of the connecting rod 1.

[0045] In actual use, the end of the connecting rod 1 is inserted into the first insertion hole 21, which contains a first threaded connection hole 211. The threaded post at the end of the connecting rod 1 is then screwed into the first threaded connection hole 211, allowing two adjacent connecting rods 1 to connect with the first threaded connection holes 211 at both ends of the connecting sleeve 2 via the threaded post at their ends. This achieves connection between the ends of each adjacent connecting rod 1. A support plate 3 is provided on the outer wall of the near end of two adjacent connecting rods 1. The support plate 3 is connected to the outer wall of the connecting rod 1, and a through hole 31 is provided on the support plate 3. Figure 1 As shown, threaded connecting posts 4 are inserted into the through holes 31 of the support plates 3 on two adjacent connecting rods 1. The threaded connecting posts 4 have threaded portions at both ends, which are inserted into the through holes 31 of the two support plates 3. Figure 5 As shown, the threaded connecting column 4 is fixedly connected to the support plate 3 by a fastening nut, so that the connecting rod 1 is connected through the connecting sleeve 2 and then connected again through the threaded connecting column 4 and the support plate 3.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
