Description

Technical Field

[0001] The present invention belongs to the field of industrial automation, and relates to an automatic alignment system for coke oven machinery, which is applied to the automatic alignment system of coke oven machinery and equipment. Background Art

[0002] Coke oven machinery and equipment are mobile machinery and equipment serving the coal chemical coke oven production process, and need to move frequently between each coking chamber to complete process operations such as coke pushing, coal charging, coke guiding, and coke receiving. To meet the production requirements, the alignment accuracy requirements for each operation point are high, usually ±5 mm. Currently, for large coke oven equipment such as 7.63 meters and 7 meters in China, the method of "an automatic identification and alignment system for coke oven machinery furnace numbers", that is, the automatic alignment technology in the form of a reading head and a coding plate, is mostly adopted. This alignment technology is mature and reliable, but there are also the following deficiencies: 1. The installation and debugging are troublesome. The coke oven consists of multiple porous coking chambers, and a coding disk corresponding to the number needs to be installed in each coking chamber, with a large workload. Moreover, the position of the coke guide machine is suspended, and the installation and adjustment are unsafe and inconvenient; 2. The later maintenance workload is large. Since the width of the coking chamber will change with time due to thermal expansion, the position of the coding disk needs to be adjusted frequently to adapt to the position change; 3. Due to the harsh environment of the coke oven, there is a large amount of soot and dust, and the lens of the reading head needs to be cleaned regularly, and the decoding board is often damaged, which brings great difficulties to the maintenance work.

[0003] Some small and medium-sized coke oven enterprises usually adopt manual alignment due to its high cost and weak maintenance strength. The accuracy is low, the efficiency is not high, and accidents are likely to occur. In this context, to achieve safe interlock operation between coke oven equipment and reduce the maintenance workload, relying on the 7-meter coke oven engineering project of Benxi Beiying, in the control scheme of the coke oven vehicle running mechanism, an automatic alignment control system based on a new type of infrared code plate decoder and code plate form is developed, which meets the control accuracy of the running positioning error better than 5 mm required by the process, and at the same time achieves a good actual control effect of rapid, stable and effective improvement of production efficiency.

[0089] Since the first number representation area 11 and the second signal representation area are symmetrically arranged, the first digit and the third digit calculated on the right side of the second signal representation area are set as hollow structures; the rest of the positions are not hollowed out;

[0107] The fifth infrared sensor module 105 and the sixth infrared sensor module 106 are arranged in parallel to scan the precise position determination area 13 to determine the final precise position of the coking chamber;

[0108] During the process of the code plate decoder horizontally running and scanning the code plate, when the infrared rays of the fifth infrared sensor module 105 and the sixth infrared sensor module 106 simultaneously pass through the precise positioning hole in the middle of the code plate, a precise positioning signal is obtained. And the precise positioning signal is fed back to the plc controller, and the plc controller controls the frequency converter to stop running.

[0109] Among them, the first infrared sensor module 101 and the second infrared sensor module 102 are arranged in parallel, the third infrared sensor module 103 and the fourth infrared sensor module 104 are arranged in parallel, and the seventh infrared sensor module 107 and the eighth infrared sensor module 108 are arranged in parallel.

[0112] Figure 5 It is a flowchart of the automatic alignment control method;

[0113] A control method for an automatic alignment system of a coke oven machine includes the following steps:

[0114] S1: Number the coking chamber positions in sequence, and respectively determine the encoder values of each coking chamber;

[0115] Obtain the position number of the target coking chamber input by the man-machine operation interface;

[0116] Compare the encoder value d1 of the current position with the encoder set value d2 of the target coking chamber.

[0117] When d1 - d2 > 0, the traveling mechanism of the coke oven machine travels forward;

[0118] When d1 - d2 < 0, the traveling mechanism of the coke oven machine travels in reverse;

[0119] When the distance between the traveling mechanism of the coke oven machine and the target coking chamber is reduced to the range where the code plate decoder 4 enters the code plate range, the code plate decoder 4 scans the code plate to achieve precise positioning of the traveling mechanism of the coke oven machine.

[0120] Furthermore, the speed control method during the traveling of the traveling mechanism of the coke oven machine is as follows:

[0121] When the distance between the traveling mechanism of the coke oven machine and the target coking chamber > the first threshold distance Dmax (set deceleration distance), the traveling mechanism of the coke oven machine travels at a high speed v1; that is, the frequency converter module operates at a high speed.

[0122] When the distance between the traveling mechanism of the coke oven machine and the target coking chamber ≤ the first threshold distance Dmax, the distance between the traveling mechanism of the coke oven machine and the target coking chamber decreases linearly, and the traveling mechanism of the coke oven machine starts to decelerate.

[0123] When the distance between the traveling mechanism of the coke oven machinery and equipment and the target carbonization chamber is less than the second threshold distance Dmin, the traveling mechanism of the coke oven machinery and equipment travels at a low speed v2, where v1 > v2.
