Description

Technical Field

[0001] The present application relates to the technical field of coke oven vehicle equipment, and in particular to a coke oven vehicle reading head interlocking purge device. Background Art

[0002] Coke oven vehicles are the core equipment in the coke production process. They are mainly composed of a coke pusher, a coal charging car, a coke intercepting car, an electric locomotive and a ground coordination system. The main function of the coke pusher is to open the furnace door on the side of the furnace body and push the coked coke out of the furnace from one side of the furnace with a coke pusher rod; the main function of the coke intercepting car is to guide the coke pushed by the coke pusher into the coke tank of the electric locomotive through the coke guide device. In daily coke quenching, the electric locomotive is responsible for pulling the coke tank trolley to transport the red coke to the elevator, and the elevator is responsible for transporting the coke tank to the dry coke quenching process; the automatic alignment system plays a very important role in the coke oven vehicle system. Figure 1 The hardware of the automatic alignment system consists of a reading head and a code disk device. A code disk corresponding to the furnace number is installed at the lower part of the coke oven end platform and the side of the furnace top track along the longitudinal center of each furnace hole. When the reading head installed at the lower center axis position of the vehicle passes through the code disk during vehicle operation, it can read the current furnace number position and give a vehicle alignment position signal to control the equipment to stop; an optical fiber module is set in the reading head to ensure that the code disk can read accurately. However, in actual use, when the optical fiber length and the cleanliness of the reading head lens are qualified, the equipment itself will still be affected by the external environment. In case of strong weather, the incident light will be refracted by water vapor, which will lead to reduced incident light intensity and inaccurate code reading. Especially in coastal areas with high humidity and more rainy days, this situation often occurs, so it needs to be improved. Utility Model Content

[0029] The following is combined with Figure 1-4 This application is described in further detail.

[0030] The embodiment of the present application discloses a coke oven vehicle reading head interlocking purge device. Figure 1 , including a reading head 2 arranged below the outer steel structure 1 of the electric locomotive. In this embodiment, the reading head 2 and the outer steel structure 1 of the electric locomotive are detachably connected by bolts, so that the reading head 2 can be quickly installed and disassembled; an installation cavity 21 is opened in the reading head 2, and a plurality of optical fiber sensors 3 are arranged in the installation cavity 21. The transmitting ends of the optical fiber sensors 3 are all arranged on the inner wall on the same side of the installation cavity 21, and the receiving ends of the optical fiber sensors 3 are uniformly arranged on the inner wall on the other side of the installation cavity 21, so that when the code disk 8 passes through the installation cavity 21, the light intensity can be adjusted to improve the reading accuracy.

[0031] Reference Figure 1 , also includes an air supply pipe 4 and a tee pipe 5, the air supply pipe 4 is connected to the air compressor of the electric locomotive for transmitting wind power. In this embodiment, the air supply pipe 4 adopts a metal hose, which has high structural strength, can ensure the stable circulation of airflow, and extend the service life of the overall structure; the tee pipe 5 includes an inlet end 51 connected to the air supply pipe 4 and two blowing ends 52, the inlet end 51 of the tee pipe 5 is connected to the air supply pipe 4 by a bolt, so that the tee pipe 5 and the air supply pipe 4 can be quickly connected or disassembled, the blowing direction of the blowing end 52 is set parallel to the passing direction of the code disk 8, and the two blowing ends 52 are not in the same plane. One of the blowing ends 52 is set close to the inner wall of the mounting cavity 21 where the transmitting end of the optical fiber sensor 3 is installed, and the other blowing end 52 is set close to the inner wall of the mounting cavity 21 where the receiving end of the optical fiber sensor 3 is installed, which facilitates the circulation and diffusion of water vapor when blowing on both sides, and avoids the situation where the air outlets of the two blowing ends 52 are facing each other, the air forms convection when blowing, and the two groups of optical fiber sensors 3 in the middle cannot achieve the blowing effect.

[0032] Reference Figure 1 , further comprising a solenoid valve 6 for controlling the on / off flow of the gas pipe 4. The solenoid valve 6 is electrically connected to a control module 7. In this embodiment, the control module 7 utilizes a PLC, which controls the opening and closing of the solenoid valve 6 through program interlocking. On rainy days, depending on the actual situation, the central control personnel manually press the purge device start button. At this time, the start signal is 1 (0 after pressing the stop button). This signal is interlocked with the locomotive running signal. When the start signal is 1 and the locomotive running signal is 1, the solenoid valve 6 is energized and opens, starting the purge device. When the start signal is 1 and the locomotive running signal is 0, the solenoid valve 6 is de-energized and the purge device does not start. If the stop button is pressed during the startup process (i.e., the start signal changes from 1 to 0), the solenoid valve 6 loses power, closes, and stops the purge device. That is, after the purge device is in use (by pressing the purge device start button), the purge device operates normally when the locomotive is running normally; when the locomotive stops running, the purge device automatically stops. This avoids unnecessary waste of resources.

[0033] The implementation principle of the interlocking purge device of the coke oven vehicle reading head in the embodiment of the present application is: after starting the solenoid valve 6, the gas supply pipe 4 transports gas toward the three-way pipe 5, and the two blowing ends 52 are used to purge the water vapor in the installation cavity 21 to improve the problem of inaccurate code reading caused by the refraction of light by water vapor in rainy days.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
