Abstract
Description
Technical fields:
[0001] This utility model relates to the technical field of coke oven gas holder equipment, and in particular to a coke oven gas holder with tilt detection function. Background technology:
[0002] The tilt of the piston during coke oven gas holder operation is a crucial safety parameter. Analysis of numerous gas holder production safety accidents reveals that most incidents were related to the piston tilt exceeding safe limits. To ensure safe gas holder operation, monitoring the piston tilt during operation is essential. Current technology often employs multiple laser rangefinders positioned at various locations within the gas holder to estimate the piston tilt angle based on the height differences between these locations. However, while this structure can accurately estimate the piston tilt angle, it is impractical in real-world applications. This is because the piston is enormous, the distances between laser rangefinders at different locations are vast, the electrical wiring is long, and the structure is complex. Furthermore, placing sensors and other electronic components inside the gas holder for extended periods makes repair difficult if these components malfunction. Additionally, coke oven gas holders lack an automatic piston tilt correction function, and the response time for correcting piston tilt is slow, all of which urgently require improvement. Utility model content:
[0003] The purpose of this utility model is to provide a coke oven gas holder with tilt detection function to solve the technical problems of existing gas holder piston tilt detection devices, such as complex structure, inconvenient maintenance, and lack of automatic correction function.
[0004] The present invention relates to a coke oven gas holder with tilt detection function, applied to a gas holder body. A piston is horizontally installed inside the gas holder body. An anti-tilt rod is vertically connected upwards at the center of the piston. An anti-tilt cylinder is vertically fitted outside the anti-tilt rod, located directly above the piston. The top of the anti-tilt cylinder extends outside the gas holder body. Several sets of correction devices are installed vertically on the anti-tilt cylinder. Each correction device includes several rolling ball correction components evenly arranged circumferentially. The rolling ball correction components are used to prevent the anti-tilt rod from tilting. A circular groove is formed at the top of the anti-tilt cylinder. Several elastic trigger components are evenly distributed circumferentially within the circular groove. A proximity switch is installed outside the elastic trigger components. The signal output terminal of the proximity switch is electrically connected to the signal input terminal of a PLC controller. The signal output terminal of the PLC controller is electrically connected to an alarm.
[0005] Furthermore, the ball straightening assembly includes a stud, and several threaded through holes are evenly distributed on the outer circumference of the anti-skew cylinder. The stud is screwed into the threaded through holes. A blind hole is provided at the inner end of the stud. A first compression spring and a straightening ball are installed sequentially from the bottom to the opening of the blind hole. The straightening ball presses against the anti-skew rod.
[0006] Furthermore, the corrective ball is made of stainless steel and has a wear-resistant coating on its surface.
[0007] Furthermore, the elastic triggering component includes a sliding column, with a plurality of through holes evenly distributed on the outer circumferential surface of the anti-skewing cylinder. The sliding column is slidably connected to the through holes. An arc plate is installed at the inner end of the sliding column, and a limiting plate is connected to the outer end of the sliding column. The limiting plate is located outside the anti-skewing cylinder. A second compression spring is fitted on the sliding column, and the two ends of the second compression spring are in contact with the arc plate and the inner wall of the anti-skewing cylinder, respectively.
[0008] Furthermore, a bracket is installed on the outer wall of the anti-slant cylinder, and the proximity switch is installed on the bracket. The proximity switch is located outside the limit plate.
[0009] Furthermore, the anti-skewing cylinder is fixedly installed on the gas holder body via a connecting beam.
[0010] The beneficial effects of this utility model are as follows: This utility model designs an anti-skewing rod on the piston, thereby converting the piston tilt monitoring into anti-skewing rod tilt monitoring, making the detection simpler and more convenient. The anti-skewing rod tilt monitoring device is located outside the gas holder, making the structure simpler and more reliable. At the same time, a correction device for the anti-skewing rod is designed to indirectly correct the piston tilt, which is worthy of widespread promotion and use. Attached image description:

Sliding column; 10. Second compression spring; 11. Limit plate; 12. Proximity switch; 13. PLC controller; 14. Alarm; and 15. Connecting beam. Detailed implementation method:
[0016] like Figure 1 , Figure 2 and Figure 4 As shown, a coke oven gas holder with tilt detection function is applied to a gas holder body 1. A piston 2 is horizontally arranged inside the gas holder body 1. An anti-tilt rod 3 is vertically connected upward at the center of the piston 2. An anti-tilt cylinder 4 is vertically fitted outside the anti-tilt rod 3. The anti-tilt cylinder 4 is fixedly installed on the gas holder body 1 by a connecting beam 15. The anti-tilt cylinder 4 is located directly above the piston 2. The top end of the anti-tilt cylinder 4 extends outside the gas holder body 1. Several sets of correction devices are installed vertically on the anti-tilt cylinder 4. The device includes a plurality of ball-rolling correction components evenly arranged along the circumference. The ball-rolling correction components are used to prevent the anti-tilt rod 3 from tilting. A circular groove 16 is provided at the top of the anti-tilt cylinder 4. A plurality of elastic trigger components are evenly arranged along the circumference in the circular groove 16. A proximity switch 12 is provided outside the elastic trigger components. The signal output terminal of the proximity switch 12 is electrically connected to the signal input terminal of the PLC controller 13. The signal output terminal of the PLC controller 13 is electrically connected to the alarm 14.
[0017] like Figure 2 As shown, the ball straightening assembly includes a stud 5. Several threaded through holes are evenly distributed on the outer circumference of the anti-skew cylinder 4. The stud 5 is screwed into the threaded through holes. A blind hole is opened at the inner end of the stud 5. A first compression spring 6 and a straightening ball 7 are installed sequentially from the bottom to the opening of the blind hole. The straightening ball 7 presses against the anti-skew rod 3. In order to improve the wear resistance of the straightening ball 7, the straightening ball 7 is made of stainless steel and coated with a wear-resistant coating.
[0018] like Figure 3 As shown, the elastic triggering component includes a sliding column 9, with several through holes evenly distributed on the outer circumferential surface of the anti-skewing cylinder 4. The sliding column 9 is slidably connected to the through holes. An arc plate 8 is installed at the inner end of the sliding column 9, and a limiting plate 11 is connected to the outer end of the sliding column 9. The limiting plate 11 is located outside the anti-skewing cylinder 4. A second compression spring 10 is fitted on the sliding column 9, and the two ends of the second compression spring 10 are in contact with the arc plate 8 and the inner wall of the anti-skewing cylinder 4, respectively. A bracket is installed on the outer wall of the anti-skewing cylinder 4, and a proximity switch 12 is installed on the bracket. The proximity switch 12 is located outside the limiting plate 11.
[0019] In specific work, such as Figures 1 to 4As shown, when piston 2 tilts slightly, piston 2 causes anti-tilt rod 3 to tilt as well. Due to the squeezing action of the corrective ball 7, the tilt of anti-tilt rod 3 can be effectively corrected, thereby controlling the tilt angle of piston 2. When piston 2 tilts significantly, piston 2 causes anti-tilt rod 3 to tilt significantly as well. At this time, anti-tilt rod 3 touches arc plate 8, causing arc plate 8 to retract, thereby causing limit plate 11 to touch proximity switch 12. Proximity switch 12 sends a signal to PLC controller 13, and PLC controller 13 controls alarm 14 to sound an alarm, prompting staff to take timely measures.
[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
