DETAILED DESCRIPTION

[0050] The technical solutions in the present application will be described clearly and completely below in combination with the specific embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0051] The coke oven is one of the important industrial furnaces in the metallurgical industry, mainly used for smelting coal into coke. After the coal is loaded into the carbonization chamber of the coke oven, it is heated by high temperature in the combustion chamber on both sides under the condition of air isolation, and finally forms porous coke through the processes of drying, pyrolysis, melting, solidification and shrinkage.

[0052] The coke oven vehicle is an important part of the coke oven, including the coal loading vehicle, the coke pushing vehicle, the coke blocking vehicle and the coke extinguishing vehicle. The coal loading vehicle is mainly used for sending coal into the oven. The coke pushing vehicle is responsible for pushing the oven with coal loaded and after the coking process, so that the coke is pushed out of the carbonization chamber. During the coke pushing process, the coke blocking vehicle is responsible for guiding the pushed-out coke to the coke extinguishing vehicle and preventing the coke from scattering around, while taking out the coke in the oven. The coke extinguishing vehicle is responsible for receiving the high-temperature coke pushed out of the carbonization chamber and transporting it to the coke extinguishing tower for extinguishing treatment, and then transporting the extinguished coke out.

[0053] With the development of technology, the "one-key coking" technology and the 5G technology are applied to the coke oven vehicle to realize the automatic operation of the coke oven vehicle and the whole coke oven system. The automatic positioning technology of the coke oven vehicle is realized by the cooperation of the reading head and the code plate. The reading head is installed on the coke oven vehicle, and the code plate is installed at the corresponding position of the coke oven. The identification of the code plate by the reading head confirms whether the coke oven vehicle is in place.

[0054] Unlike other fields in the prior art, the temperature of the coke oven system during operation is relatively high. The high-temperature environment can cause wavelength drift of the light wave emitted by the light sensor, resulting in a certain deviation in the measurement results of the reading head.

[0055] The present invention provides a coke oven reading head with temperature compensation function, comprising a housing 1, a mounting bracket 2, a laser emitter 3, a positioning pin 4, a spring 5, a moving bracket 6, and a fixing knob 7. The reading head is installed on a coke oven vehicle. By adjusting the position of the laser emitter 3, the detection deviation caused by the high temperature environment can be compensated, thereby accurately detecting whether the position of the coke oven vehicle is in place.

[0056] After the laser emitted by laser emitter 3 shines on the encoding board, the different reflective properties of the encoding board surface will form reflected light of varying intensity. The photosensitive receiving device in the reading head receives the reflected light and converts it into electrical signals. The intensity of these electrical signals corresponds to the intensity of the reflected light. By amplifying, filtering, and shaping the electrical signals, the electrical signals are converted into digital or analog signals for further decoding and processing, thereby determining the position of the coke oven vehicle.

[0057] The laser emitter 3 is fixedly mounted inside the mounting bracket 2, which is spaced apart inside the outer casing 1. The end of the mounting bracket 2 is provided with a positioning groove 201, and the positioning pin 4 is fixedly mounted at the end of the outer casing 1. The spring 5 is abutted at the end of the mounting bracket 2. By using the spring 5 to abut against the mounting bracket 2, the positioning pin 4 can be engaged with the positioning groove 201 to fix the mounting bracket 2 and the laser emitter 3. The relative position of the positioning pin 4 and the outer casing 1 is adjustable. By adjusting the installation position of the positioning pin 4, the laser emitter 3 can be adjusted, thereby compensating for the detection deviation of the reading head.

[0058] There are two ambient temperatures during the operation of the coke oven vehicle: one is the normal temperature environment during transportation, and the other is the high temperature environment when it is close to the coke oven. Therefore, positioning slots 201 are opened at both ends of the mounting frame 2, and two positioning pins 4 and two springs 5 ​​are set. The two positioning pins 4 are fixedly set at both ends of the outer shell 1, and the positions of the two positioning pins 4 correspond to the two ambient temperatures of the coke oven vehicle. The two springs 5 ​​are respectively abutted at both ends of the mounting frame 2. The movable frame 6 is slidably set on the outer shell 1, and its two ends abut against the ends of the two springs 5 ​​away from the mounting frame 2.

[0059] like Figure 2 As shown, assuming the right end of the outer shell 1 is the first end, when the right positioning groove 201 is engaged with the right positioning pin 4, the reading head is used in the normal temperature environment during the transportation of coke oven vehicles. When the left positioning groove 201 is engaged with the left positioning pin 4, the reading head is used in the high temperature environment when the coke oven vehicle is close to the coke oven.

[0060] During transport, the coke oven vehicle slides the movable frame 6 towards the first end. At this time, the spring force of the spring 5 away from the first end is greater than that of the spring 5 near the first end, thereby pushing the mounting frame 2 to move to the right, causing the positioning groove 201 near the first end to engage with the positioning pin 4 near the first end. When the coke oven vehicle moves to a position close to the coke oven, such as... Figure 3 As shown, the movable frame 6 is slid away from the first end. At this time, the elastic force of the spring 5 away from the first end is less than that of the spring 5 near the first end, thereby pushing the mounting frame 2 to move to the left, so that the positioning groove 201 away from the first end engages with the positioning pin 4 away from the first end, thereby realizing the rapid switching of the laser emitter 3 between the two working conditions and ensuring the accuracy of the reading head detection results.

[0061] like Figure 2 and Figure 3 As shown, the fixing knob 7 is connected to the movable frame 6 by a threaded connection and abuts against the outer shell 1. When the fixing knob 7 is rotated away from the outer shell 1, the movable frame 6 can slide. When the fixing knob 7 is rotated to abut against the outer shell 1, the movable frame 6 can be fixed for adjustment and locking. Of course, in order to improve the automation of the laser emitter 3 position adjustment, the fixing knob 7 can be omitted, and the movable frame 6 can be directly connected to the output end of telescopic devices such as cylinders and electric cylinders.

[0062] Mounting bracket 2 includes a frame 21, a retainer 22, and two limiting rings 23, such as Figure 3 and Figure 11 As shown, the frame 21 is spaced apart inside the outer shell 1, the positioning groove 201 is located at both ends of the frame 21, the frame 21 is provided with a spherical mounting cavity 202, the fixture 22 is spherical and is fixedly installed in the mounting cavity 202, and the laser emitter 3 is fixedly installed in the fixture 22; the position of the fixture 22 in the mounting cavity 202 can be adjusted. For example, if the fixture 22 is made of a material with high friction such as rubber, when a large rotational force is applied to the fixture 22, the fixture 22 can be rotated, thereby adjusting the installation angle of the laser emitter 3.

[0063] Two limiting rings 23 are respectively fixedly installed at both ends of the frame 21, such as... Figure 12 As shown, one end of the spring 5 is engaged within the limiting ring 23, thereby preventing the spring 5 from falling off during use and ensuring the normal operation of the reading head.

[0064] like Figure 2 and Figure 3 As shown, the axis of the limiting ring 23 coincides with the axis of the positioning groove 201, so that the spring 5 can apply a uniform and stable force to the frame 21, avoiding problems such as the frame 21 tilting.

[0065] To improve the connection stability between the locating pin 4 and the mounting bracket 2, it is preferable to have multiple surfaces on the locating pin 4 mate with the mounting bracket 2; such as Figure 5 As shown, a protruding structure is provided at one end of the positioning pin 4. The outer diameter of the protruding structure is smaller than the end outer diameter of the positioning pin 4. The periphery of the protruding structure is a conical surface 401, and the end face of the positioning pin 4 is a flat surface 402. The conical surface 401 and the flat surface 402 are continuously arranged, and the conical surface 401 abuts against the inner wall of the positioning groove 201, and the flat surface 402 abuts against the mounting bracket 2, thereby improving the fixing reliability of the mounting bracket 2.

[0066] To prevent the mounting bracket 2 from rotating around the axis of the positioning groove 201 during operation, it is preferable that the protruding structure at the end of the positioning pin 4 and the positioning groove 201 are both set in the shape of a pyramid or frustum; it is preferable that the protruding structure and the positioning groove 201 are both set in the shape of a square pyramid, that is, the cone surface 401 is also in the shape of a square pyramid.

[0067] The outer casing 1 has a movable hole 101. The positioning pin 4 includes a pin body 41 and two rotating parts 42. The pin body 41 is disposed within the movable hole 101, the inner diameter of which is larger than the outer diameter of the pin body 41, such as an oblong or elliptical shape. The two rotating parts 42 are threadedly connected to the pin body 41 and respectively abut against the inner and outer sides of the outer casing 1. Figure 5 As shown, when the rotating part 42 on the right is rotated to move to the right, the pin 41 can be moved and its position adjusted. After the pin 41 moves to the designated position, the rotating part 42 on the right is rotated again to hold the outer shell 1, thereby fixing the pin 41 and realizing the two-dimensional movement of the pin 41 and the laser emitter 3.

[0068] like Figure 5 As shown, when the rotating part 42 on the right is rotated to move it to the right, the pin 41 can also be rotated, thereby adjusting the pitch angle of the laser emitter 3.

[0069] like Figure 5 As shown, when the two rotating parts 42 are rotated in the same direction, or when the two rotating parts 42 are kept stationary while the pin 41 is rotated, the pin 41 can be moved along its axis. In conjunction with the above-mentioned movement operation, the pin 41 and the laser emitter 3 can be adjusted in all directions, and the laser emitter 3 can be adjusted to different positions as required.

[0070] like Figure 5 As shown, the left rotating component 42 is located inside the outer casing 1, making it inconvenient to rotate. Furthermore, because the left rotating component 42 is difficult to fix, rotating the pin 41 will also cause the left rotating component 42 to rotate, affecting the adjustment efficiency of the pin 41. To solve this problem, as... Figure 11 and Figure 12As shown, a locking block is provided on the rotating part 42, allowing the locking block to extend into the movable hole 101 and engage with the movable hole 101. This engagement prevents the rotating part 42 from rotating with the pin 41, thereby improving the ease of operation of the pin 41.

[0071] Specifically, the pin 41 includes an outer tube 411, a snap-fit ​​connector 412, a slide rod 413, a screw head 414, and a retaining plate 415, such as Figure 4 As shown, the outer tube 411 is connected to the rotating part 42 by a threaded connection, and the snap-fit ​​connector 412 is fixedly installed at one end of the outer tube 411 and snaps into the positioning groove 201.

[0072] like Figures 6-10 As shown, a cross-shaped sliding hole is opened in the outer tube 411, and the sliding hole extends to the end of the snap connector 412 away from the outer tube 411. A sliding rod 413 is slidably arranged in the sliding hole, so that the sliding rod 413 is slidably arranged in the outer tube 411. A screw head 414 is rotated and arranged at the end of the sliding rod 413 away from the snap connector 412, and the screw head 414 is connected to the outer tube 411 by thread engagement. The abutment plate 415 is fixedly arranged on the sliding rod 413. The conical surface 401 is the periphery of the snap connector 412, and the plane 402 is the side of the abutment plate 415 away from the sliding rod 413.

[0073] like Figure 3 and Figure 5 As shown, when the snap-fit ​​connector 412 snaps into the positioning groove 201, the abutment plate 415 can abut against the mounting bracket 2, thereby improving the connection stability between the two.

[0074] like Figure 5 As shown, the locating pin 4 on the right is engaged with the mounting bracket 2, as... Figure 4 As shown, the left-side clip connector 412 is spaced apart from the mounting bracket 2, and the left end of the mounting bracket 2 is fixed by the elastic force of the spring 5. When the coke oven vehicle is subjected to large vibrations, the spring 5 can be used to buffer the laser emitter 3, improve the fixing firmness of the laser emitter 3, and avoid the mounting bracket 2 from being damaged due to excessive force.

[0075] However, the buffering effect of spring 5 will have a certain impact on the detection results of the reading head. In some scenarios with extremely high detection accuracy requirements, it is necessary to make the laser emitter 3 rigidly connected to the outer shell 1. At this time, rotate the screw head 414 without rotating the outer tube 411. By using the threaded engagement between the screw head 414 and the outer tube 411, the slide rod 413 and the abutment plate 415 are driven to move to the right, so that the abutment plate 415 abuts against the left side of the mounting bracket 2, making the mounting bracket 2 rigidly connected to the outer shell 1. Since the position of the outer tube 411 remains unchanged, when it is necessary to make the mounting bracket 2 engage with the positioning pin 4 on the left, rotate the screw head 414 in the opposite direction, so that the abutment plate 415 abuts against the right end of the outer tube 411, and the abutment plate 415 can be reset.

[0076] As shown in Figure 9 The outer tube 411 is provided with a blind hole at the end away from the clamping joint 412, and the inner wall of the blind hole is provided with internal threads. When the abutting plate 415 is away from the outer tube 411, the screw head 414 is connected with the internal threads through threaded connection. As shown in Figure 11 When the abutting plate 415 abuts against the end of the outer tube 411, the screw head 414 is just out of the blind hole, so that the abutting plate 415 will not extrude the end of the outer tube 411 when the screw head 414 is rotated, thereby achieving a certain protection effect.

[0077] The above embodiments are switching of two environmental conditions, and the switching of multiple environmental conditions can also be realized by setting multiple moving frames 6, multiple positioning pins 4 and multiple positioning grooves 201, thereby improving the working condition adaptability of the reading head.

[0078] The use method of the coke oven reading head with temperature compensation function is as follows:

[0079] First, the positions of the two positioning pins 4 are adjusted, so that when the positioning groove 201 is connected with the left positioning pin 4, the laser emitter 3 is in the installation position of the normal temperature condition, and when the positioning groove 201 is connected with the right positioning pin 4, the laser emitter 3 is in the installation position of the high temperature condition. Then, the laser emitter 3 is switched to the position of the required working condition by adjusting the position of the moving frame 6, and the laser emitter 3 can be switched in different working conditions by reciprocating the moving frame 6, thereby compensating for the detection deviation of the reading head caused by temperature. During the period, if the detection result of the reading head is required to be higher, the abutting plate 415 can be used to assist in fixing the mounting frame 2.

[0080] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
