Description

Technical Field

[0001] This utility model relates to the field of sintering machine technology, specifically to an automatic detection device for fracture faults of the sliding plate of a sintering machine trolley. Background Technology

[0002] In the sintering production process, the bogie slide plate is a key component that carries the sintering material and completes the sintering process; its integrity directly affects the stable operation of the entire sintering production line. Currently, this component is driven by head and tail star wheels to achieve cyclic operation, and it is subjected to both mechanical and thermal stresses over a long period of time, making it highly susceptible to wear, cracks, and even fractures. Particularly noteworthy is that, due to structural characteristics and stress distribution, the edges of the bogie slide plate often become high-risk areas for fractures. The currently prevalent manual inspection method not only has blind spots but also fails to achieve real-time fault identification. When a sudden fracture occurs, it can easily lead to a chain reaction of equipment failures or even system shutdown, severely impacting production efficiency and equipment safety. Existing technologies lack effective means to continuously monitor the operating status of the bogie slide plate, making the development of an automatic detection device specifically for bogie slide plate fracture faults particularly urgent. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing an automatic detection device for fracture faults of the sintering machine trolley slide plate.

[0004] This utility model is achieved through the following technical solution: an automatic detection device for fracture fault of sintering machine trolley slide plate is provided, including a crossbeam fixed to the side of the sintering machine column, a mounting column fixed to the lower end of the crossbeam, and a vertical detection rod. It also includes an upper connecting rod and a lower connecting rod arranged in parallel. The two ends of the upper connecting rod are respectively hinged to the detection rod and the mounting column, and the two ends of the lower connecting rod are respectively hinged to the detection rod and the mounting column. The lower end of the detection rod is equipped with a roller that fits against the upper surface of the trolley slide plate. An upper switch plate and a lower switch plate are fixedly connected to the detection rod. An upper micro switch adapted to the upper switch plate and a lower micro switch adapted to the lower switch plate are fixedly connected to the mounting column.

[0005] In this design, the upper and lower connecting rods form a parallelogram structure, allowing the detection rod to swing vertically. Regardless of whether the trolley slide breaks and falls downwards or abnormally pops upwards, an alarm signal can be triggered immediately through the precise coordination of the upper and lower microswitches.

[0006] As an optimization, a switch mounting plate is bolted to the side of the mounting column, and the upper and lower microswitches are respectively mounted on the upper and lower end faces of the switch mounting plate. In this solution, the upper and lower microswitches are installed through the switch mounting plate.

[0007] As an optimization, a roller frame is hinged to the lower end of the detection rod, and rollers are installed at both ends of the roller frame. In this solution, rollers are installed at both ends of the roller frame, and the two rollers achieve contact with the trolley slide.

[0008] As an optimization, the lower pin passes through the lower connecting rod, roller frame, and detection rod, realizing the hinge between the detection rod and the roller frame, as well as the hinge between the lower connecting rod and the detection rod. This ensures that the hinges between the detection rod and the roller frame, and between the lower connecting rod and the detection rod, are located on the same rotating shaft, facilitating installation and simplifying the structure.

[0009] As an optimization, two lower connecting rods are provided and located on both sides of the roller frame. This ensures structural stability at the hinge position.

[0010] As an optimization, the roller frame includes two side-by-side roller frame plates, with the detection rod and rollers located between the two roller frame plates. This facilitates the installation of the detection rod and rollers.

[0011] As an optimization, a torsion spring is installed on the hinge shaft between the upper connecting rod and the mounting column to drive the upper connecting rod to swing downwards. This increases the downward pressure on the trolley slide plate.

[0012] The beneficial effects of this utility model are as follows: The automatic detection device for fracture fault of sintering machine trolley slide plate of this utility model realizes real-time intelligent monitoring of the running status of trolley slide plate through an innovative design that combines mechanical transmission and electrical detection.

[0013] The device employs a unique double-link hinge structure and a bidirectional triggering mechanism. Whether the trolley slide breaks and falls downwards or abnormally pops upwards, an alarm signal is immediately triggered through the precise coordination of the upper and lower microswitches. This bidirectional detection mechanism greatly improves the reliability and comprehensiveness of fault identification, effectively overcoming the lag and limitations of traditional manual inspections. The specially designed roller contact detection method ensures continuous sensing of the trolley slide surface condition while avoiding false triggering under normal operating conditions through reasonable gap settings.

[0014] The device adopts a split installation structure, which facilitates on-site installation and commissioning while ensuring long-term stable operation under harsh conditions. The widespread application of this detection device will significantly improve the automation level of the sintering production line, effectively preventing serious equipment accidents through early fault warnings, providing a reliable guarantee for the continuous and efficient operation of the sintering machine, and greatly reducing maintenance costs and production losses.

[0016] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to describe the solution.

[0017] like Figures 1-5 As shown, the present invention discloses an automatic detection device for fracture fault of sintering machine trolley slide plate, comprising a crossbeam 14 fixed to the side of the sintering machine column 16, a mounting column 13 fixed to the lower end of the crossbeam 14, and a vertical detection rod 1. Figure 4 As shown, the crossbeam 14 is horizontally arranged and extends along the left and right direction of the sintering machine. The two ends of the crossbeam 14 are connected to the sintering machine columns 16 on both sides by bolts, and the crossbeam 14 is located between the upper and lower trolley slides.

[0018] The upper end of the mounting column 13 is welded and fixed to the lower end face of the crossbeam 14. The mounting column 13 is a vertical rectangular tube. The detection rod 1 is also a vertical rectangular tube, and the lower end of the detection rod 1 is lower than the lower end of the mounting column 13. It also includes an upper connecting rod 2 and a lower connecting rod 3 arranged in parallel. Both the upper connecting rod 2 and the lower connecting rod 3 are long strip steel plates.

[0019] The upper connecting rod 2 is hinged to the detection rod 1 and the mounting column 13 at both ends, respectively. Specifically, there are two upper connecting rods 2, located on both sides of the mounting column 13 and the detection rod 1. One end of the upper connecting rod 2 is hinged to the detection rod 1 via a horizontal upper pin 11, and the other end is hinged to the mounting column 13 via a horizontal pin, allowing the upper connecting rod 2 to swing up and down.

[0020] The lower connecting rod 3 is hinged to the detection rod 1 and the mounting column 13 at both ends, respectively. Specifically, there are two lower connecting rods 3, located on both sides of the mounting column 13 and the detection rod 1. One end of the lower connecting rod 3 is hinged to the lower end of the detection rod 1 via a horizontal lower pin 10, and the other end is hinged to the mounting column 13 via a horizontal pin, allowing the lower connecting rod 3 to swing up and down.

[0021] The upper connecting rod 2 and the lower connecting rod 3 form a parallelogram structure, allowing the detection rod 1 to swing vertically.

[0022] An upper switch plate 5 and a lower switch plate 7 are fixedly connected to the detection rod 1. A switch mounting plate 12 is bolted to the side of the mounting column 13. An upper micro switch 6 adapted to the upper switch plate 5 and a lower micro switch 8 adapted to the lower switch plate 7 are fixedly connected to the mounting column 13. In this embodiment, the upper micro switch 6 and the lower micro switch 8 are respectively installed on the upper and lower end faces of the switch mounting plate 12. Both the upper switch plate 5 and the lower switch plate 7 are horizontally arranged, and their lengths should be greater than 10cm. This ensures that the detection rod 1 will not interfere with the switch mounting plate 12 when it moves horizontally, while the upper switch plate 5 and the lower switch plate 7 can trigger the upper micro switch 6 and the lower micro switch 8.

[0023] The lower end of the detection rod 1 is hinged to a roller frame 4. In this embodiment, the lower pin 10 passes through the lower connecting rod 3, the roller frame 4 and the detection rod 1, realizing the hinge connection between the detection rod 1 and the roller frame 4 as well as the hinge connection between the lower connecting rod 3 and the detection rod 1.

[0024] The roller frame 4 includes two parallel roller frame plates, with the detection rod 1 and roller 9 located between the two roller frame plates. Two lower connecting rods 3 are located on both sides of the roller frame 4. The lower pin 10 passes through the center of the roller frame plate, which is elongated and extends along the direction of movement of the trolley slide plate.

[0025] Rollers 9 are installed at both ends of the roller frame 4. The rollers 9 rotate through bearings and are in contact with the upper surface of the trolley slide.

[0026] In order to increase the downward pressure of the roller 9 and the trolley slide, a torsion spring is installed on the hinge shaft of the upper connecting rod 2 and the mounting column 13 to drive the upper connecting rod 2 to swing downward.

[0027] How to use this utility model: like Figure 4 , 5 As shown, the trolley slide plate 15 passes around the tail star wheel 17 and the head star wheel 18 of the sintering machine. The rotation of the tail star wheel 17 and the head star wheel 18 of the sintering machine drives the trolley slide plate 15 to move in a cycle.

[0028] The crossbeam 14 is fixedly connected between the two sintering machine columns 16, and two sets of detection devices are set up to detect the two edge positions of the upper end face of the lower trolley slide plate 15, mainly because the edges are the most prone to breakage.

[0029] The roller 9 is attached to the upper surface of the lower trolley slide plate 15. During normal operation, there is a 10mm gap between the upper switch plate 5 and the upper micro switch 6, and a 10mm gap between the lower switch plate 7 and the lower micro switch 8. When the trolley slide plate 15 breaks and falls, the detection rod 1 falls due to gravity and the pressure of the torsion spring. The upper switch plate 5 triggers the upper micro switch 6, thereby triggering the alarm. If the trolley slide plate 15 breaks and pops upward, it pushes the detection rod 1 upward, and the lower switch plate 7 triggers the lower micro switch 8, which also triggers the alarm.
