Description

Technical Field

[0001] The utility model relates to the field of auxiliary equipment for the metallurgical industry, and particularly relates to a foreign object early warning system for the track of a converter steel ladle car. Background Technique

[0002] The metallurgical industry is one of the important basic industries of the national economy, mainly including ferrous metallurgy (such as the production of pig iron, steel and ferroalloys) and non-ferrous metallurgy (such as the production of non-ferrous metals such as copper, aluminum and zinc). During the process of steel smelting, the steel slag adhered to positions such as the furnace mouth and oxygen lance sometimes falls off. Sometimes, foreign objects such as steel slag or oxygen lance skins fall onto the track of the steel ladle car. Small foreign objects are swept away by the rail sweeper, while large ones cannot be swept away. If not discovered in time, the steel ladle car cannot reach the tapping position during tapping, and at this time, the foreign objects need to be cleared before tapping.

[0003] The existing full-process monitoring and positioning structure for the operation route of a converter steel ladle car with the patent application number CN201921370507.0 realizes the real-time monitoring of the position of the steel ladle car through the cooperation of a laser transmitter-receiver and a laser transmitting prism. When the steel ladle car runs to a preset position, an alarm device will be triggered to remind the operator in the form of sound and light; the existing device for detecting and alarming the position of converter slag and steel ladle in a steel mill with the patent application number CN201721221372.2 uses the working principle of a direct reflection type laser detector and installs it at a suitable position. When the steel and slag ladle cars drive to under the furnace, the actual position of the steel slag ladle car is detected and judged by using the signal of the detection mechanism.

[0004] As described above, the monitoring systems serving the safe operation of the converter steel ladle car in the prior art usually only monitor the positions of the steel ladle car and the slag ladle car, and do not have a foreign object detection system for the track on which the steel ladle car and the slag ladle car travel, neglecting the prevention of the risk of foreign objects on the track. Content of the Utility Model

[0005] The utility model provides a foreign object early warning system for the track of a converter steel ladle car to solve the technical problem of neglecting the prevention of the risk of foreign objects on the track in the prior art.

[0006] To solve the above problems, the foreign object early warning system for the track of a converter steel ladle car provided by the utility model adopts the following technical scheme: including an infrared transmitter, an infrared receiver, and an alarm device. The infrared transmitter is installed directly above the track at the converter end of the steel ladle car, and the infrared receiver is installed directly above the track at the converter end of the slag car. The infrared receiver corresponds to the infrared transmitter and is electrically connected to the infrared transmitter. The alarm device is electrically connected to the infrared receiver and gives an audible and visual alarm when the infrared is interrupted.

[0007] Furthermore, it also includes a camera installed at a suitable position where the track under the converter can be seen.

[0008] Further, it also includes a monitoring display, which is electrically connected to the camera to display the camera image.

[0009] Further, the monitoring display and the alarm device are integrated on the console.

[0010] Further, based on the track, the heights of the infrared emitter and the infrared receiver are the same.

[0011] Further, in the horizontal direction, both the infrared emitter and the infrared receiver are (5 - 10) cm away from the track.

[0012] Further, the ladle car and the slag car are respectively located on both sides of the converter. The tracks slidably engaged with the ladle car and the slag car include two groups. The infrared emitters and the infrared receivers respectively include two groups, and the two groups of the infrared emitters and the infrared receivers respectively correspond to the two groups of the tracks one by one.

[0013] The beneficial effect of the converter ladle car track foreign object warning system provided by the present utility model is that: through the combination of infrared detection and the camera, the system can monitor in real time whether there are foreign objects on the ladle car track. Once an abnormality is found, an audible and visual alarm is immediately issued, effectively preventing safety accidents caused by track foreign objects and improving the safety of production operations.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present utility model.

[0020] The quantity of any element in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning.

[0021] Next, with reference to several representative embodiments of the present utility model, the principles and spirit of the present utility model will be elaborated in detail.

[0022] The converter steel ladle car track foreign object warning system provided by the present utility model, as Figure 1 、 2 shown, includes an infrared emitter 1, an infrared receiver 2, and an alarm device 3.

[0023] In this embodiment, the infrared emitter 1 is installed at the end of the steel ladle car 6 near the converter 8 and directly above the track 9, continuously emitting infrared light. The infrared receiver 2 is installed at the end of the slag car 7 near the converter 8 and directly above the track 9. The infrared receiver 2 corresponds to the infrared emitter 1 and is electrically connected to the infrared emitter 1. The infrared receiver 2 is responsible for receiving the infrared light from the infrared emitter 1. When there is no foreign object on the track 9, the infrared light can smoothly transmit from the infrared emitter 1 to the infrared receiver 2, and the system is in a normal state. Once a foreign object appears on the track 9, such as an iron block, waste, etc., these foreign objects will block the propagation of the infrared light, resulting in the infrared receiver 2 not receiving the infrared signal. At this time, the system determines it as "infrared interruption".

[0024] In this embodiment, the alarm device 3 is electrically connected to the infrared receiver 2 and emits a sound and light alarm when infrared interruption occurs. Once the system detects infrared interruption, it immediately determines that there is a foreign object on the track 9 and triggers the alarm device 3 to emit a sound and light alarm signal to remind the operator to pay attention.

[0025] In this embodiment, it further includes a camera 4, which is installed at a suitable position where the track 9 under the converter 8 can be seen, and captures the video images of the track 9 and its surrounding area in real time. In this embodiment, the camera 4 includes one or a group.

[0026] In this embodiment, a monitoring display 5 is also included, which is electrically connected to the camera 4 to display the camera 4 image, and the image captured by the camera 4 is displayed on the screen in real time for operators and managers to view. In this embodiment, the monitoring display 5 and the alarm device 3 are integrated on the control console 10 of the duty room. The operator can monitor the running status of the ladle car 6 and the track 9 in real time in the duty room, and respond to the alarm signal quickly when necessary.

[0027] In this embodiment, based on the track 9, the infrared transmitter 1 and the infrared receiver 2 are at the same height to ensure that the transmission path of the infrared light is stable and reliable. In other embodiments, the heights of the infrared transmitter 1 and the infrared receiver 2 can be adjusted according to the minimum value of foreign matter on the track 9 that needs to be warned.

[0028] In this embodiment, in the horizontal direction, the infrared transmitter 1 and the infrared receiver 2 are both (5-10) cm away from the track 9 to ensure that the infrared light can accurately cover the track 9 area while avoiding being mistakenly triggered by normal structures on the track 9 (such as track 9 fixings).

[0029] In this embodiment, the ladle car 6 and the slag car 7 are respectively located on both sides of the converter 8 , and the ladle car 6 and the slag car 7 run on the same set of tracks 9 .

[0030] In this embodiment, the track 9 that can slide with the ladle car 6 and the slag car 7 includes two groups, and the two groups of tracks 9 are parallel and independent, so that the ladle car 6 and the slag car 7 can run smoothly. In this embodiment, the infrared transmitter 1 and the infrared receiver 2 each include two groups, and the two groups of infrared transmitters 1 and infrared receivers 2 correspond to the two groups of tracks 9 one by one, forming two independent infrared detection barriers. When there are no foreign objects on the two groups of tracks 9, the infrared light emitted by the two groups of infrared transmitters 1 can be smoothly received by the corresponding infrared receivers 2, and the system is in a normal state. Once a foreign object appears on any group of tracks 9 and blocks the propagation of infrared light, the corresponding infrared receiver 2 will detect the infrared interrupt signal and immediately transmit the signal to the alarm device 3.

[0031] The working principle of the foreign object early warning system for the converter 8 ladle car 6 track 9 provided by the utility model is as follows: the system can detect foreign objects on the track 9 in real time to ensure timely discovery and handling of potential safety hazards. Through infrared detection technology, the system can accurately determine whether there are foreign objects on the track 9 to avoid false alarms and missed alarms. Once a foreign object is detected, the system immediately sends out an audible and visual alarm signal to remind the operator to respond quickly and take measures.

[0032] Based on the above description of this specification, those skilled in the art can also understand the terms used as follows. For example, terms indicating orientation or positional relationships such as "upper", "lower", "front", "rear", "left", "right", "width", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings of this specification. They are only for the purpose of facilitating the description of the solution of the present utility model and simplifying the description, rather than explicitly or implicitly indicating that the devices or elements involved must have the specific orientation, be constructed and operated in the specific orientation. Therefore, the above terms of orientation or positional relationships cannot be understood or interpreted as limitations on the solution of the present utility model.

[0033] In addition, in the description of this specification, the meaning of "a plurality of" is at least two, such as two, three or more, etc., unless otherwise specifically defined.
