Description

Technical Field

[0001] The utility model relates to the technical field of vehicle positioning, in particular to a centering system for SCP large vehicles. Background Art

[0002] The SCP large vehicle is a highly integrated coke oven equipment. The SCP large vehicle integrates three processes of tamping, coal charging and coke pushing to improve the efficiency and automation level of coke oven production. In order to ensure the accuracy of the position when the SCP large vehicle pushes coking coal into the carbonization chamber after completing tamping, coal charging and coke pushing, a centering system is designed for the SCP large vehicle. The SCP large vehicle centering system relies on a traveling encoder for centering. The centering principle is as follows: after the SCP large vehicle automatically travels to the current furnace number area according to the tapping sequence number and the centering position given by the traveling encoder, it guides the SCP large vehicle into the furnace number area and identifies the code plate corresponding to the tapping sequence number; when the SCP large vehicle enters the furnace number area and completes the identification of the code plate corresponding to the tapping sequence number, the SCP large vehicle centering system resets the initial position of the traveling encoder to zero. At this time, the centering value displayed on the monitoring screen of the SCP large vehicle operation console is zero, and the centering is completed. Further, the SCP large vehicle is controlled to perform coke pushing and coal charging according to the centering result.

[0003] However, during the operations of tamping, coal charging and coke pushing of the SCP large vehicle, vibrations are likely to occur. The traveling encoder in the existing SCP large vehicle centering system is affected by the vibrations, which easily causes the centering value of the traveling encoder displayed on the monitoring screen of the SCP large vehicle operation console to change, resulting in the obtained centering accuracy of the SCP large vehicle being unable to reflect the actual centering situation of the SCP large vehicle, and making the centering value displayed on the monitoring screen lose its reference value.

[0025] The following combines the attached drawings and embodiments to further describe in detail the specific implementation manner of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0026] As Figures 1 to 5 shown, a positioning system for an SCP large vehicle provided by the present utility model includes an inverted U-shaped reading head 1, a code plate 2, an L-shaped fixing bracket 4, an identification boss 5, a laser sensor 6 and a controller. The inverted U-shaped reading head 1 is connected to the outer side surface of the bottom of the SCP large vehicle. The horizontal part of the L-shaped fixing bracket 4 is fixed on the outer side of the running track of the SCP large vehicle. A plurality of reading holes 21 for allowing the reading end of the inverted U-shaped reading head 1 to read position data are provided in the upper part of the code plate 2. The plurality of reading holes 21 are distributed at intervals and in parallel in the upper part of the code plate 2. Two waist-shaped holes 22 are provided at intervals in the same horizontal direction at the lower part of the code plate 2. The code plate 2 is detachably connected to the vertical part of the L-shaped fixing bracket 4 through two fasteners 3 and two waist-shaped holes 22. The code plate 2 is located between the two inner side surfaces opposite to the inverted U-shaped reading head 1. One side of the laser sensor 6 is fixed on one of the inner side surfaces of the inverted U-shaped reading head 1. The emitting end on the other side of the laser sensor 6 is aligned with the top end of the identification boss 5;

[0027] The longitudinal cross-sectional shape of the identification boss 5 is a stepped triangle. The two side edges of the identification boss 5 gradually rise layer by layer in a stepped manner from bottom to top. The identification boss 5 is detachably connected to the vertical part of the L-shaped fixing bracket 4 through one of the waist-shaped holes 22 on the code plate 2. The inverted U-shaped reading head 1 and the laser sensor 6 are both electrically connected to the controller, and the controller is electrically connected to the monitoring screen of the SCP large vehicle.

[0028] Specifically, the fastener 3 in the present utility model is a bolt. The measurement distance of the laser sensor 6 in the present utility model is 50 mm. The distance between the emitting end of the laser sensor 6 and one side surface of the code plate 2 in the present utility model is 50 mm.

[0029] By connecting the inverted U-shaped reading head 1 to the outer side of the bottom of the SCP large vehicle, connecting the code plate 2 to the vertical part of the L-shaped fixing bracket 4, and fixedly connecting the horizontal part of the L-shaped fixing bracket 4 to the outside of the running track of the SCP large vehicle; when the SCP large vehicle and the inverted U-shaped reading head 1 run to the furnace number area, the reading end of the inverted U-shaped reading head 1 can confirm whether the SCP large vehicle has completed alignment by identifying multiple reading holes 21 on the code plate 2;

[0030] By setting the identification boss 5 as a stepped triangle, after the SCP large vehicle runs to the furnace number area and completes alignment, the SCP large vehicle starts operations such as ramming, coal charging, and coke pushing. At this time, the controller controls the laser sensor 6 to start. The laser sensor 6 emits a light beam through the emitting end and aims at the top of the identification boss 5. During the operation of the SCP large vehicle, the laser sensor 6 can measure the distance to the top of the identification boss 5 in real time and transmit the signal to the controller. The controller can judge whether there is a position offset phenomenon of the SCP large vehicle during the operation based on the data measured by the laser sensor 6, and display the measured data on the monitoring screen, so as to obtain accurate alignment data of the SCP large vehicle, reflecting the actual alignment situation of the SCP large vehicle, and improving the reference value of the alignment value displayed on the monitoring screen of the SCP large vehicle operation console.

[0031] Optionally, the height of the identification boss 5 is 11 mm, and the identification boss 5 is provided with twenty-one steps. Among them, ten steps are provided on each side of the identification boss 5, and one step is provided at the central position. The height of each step is 1 mm, the width is 1 mm, and the length is 10 mm.

[0032] Specifically, the number of steps provided in the identification boss 5 and the dimensions such as the length, width, and height of each step can be adjusted according to specific actual situations. The present invention can be applied to the situation where the offset range of the SCP large vehicle is ±10 mm.

[0033] In a specific implementation manner, first, the SCP large vehicle and the inverted U-shaped reading head 1 run to the furnace number area. The reading end of the inverted U-shaped reading head 1 is used to identify multiple reading holes 21 on the code plate 2 and transmit the signal to the controller, and the controller judges whether the SCP large vehicle has completed preliminary alignment at this time;

[0034] Afterwards, when the controller determines that the SCP large vehicle has completed the preliminary alignment, the controller controls the SCP large vehicle to perform operations such as tamping, coal charging, and coke pushing, and controls the activation of the laser sensor 6. The laser sensor 6 reads the distance between its emitting end and the top of the identification boss 5. The specific reading process is as follows: When the SCP large vehicle completes the preliminary alignment, at this time, the emitting end of the laser sensor 6 is opposite to the top of the highest step of the identification boss 5. Then, the controller calculates the distance between the emitting end of the laser sensor 6 and the identification boss 5, that is, 50 mm - 11 mm. Therefore, when the SCP large vehicle completes the preliminary alignment, the distance between the emitting end of the laser sensor 6 and the identification boss 5 is 39 mm, that is, the zero distance between the emitting end of the laser sensor 6 and the identification boss 5 is 39 mm. At this time, the value displayed on the monitor screen of the SCP large vehicle controlled by the controller is 0; when the SCP large vehicle is operating, if the value calculated by the controller is greater than 39 mm, the value displayed on the monitor of the SCP large vehicle will be greater than 0, which proves that the SCP large vehicle does have a position offset during the operation process;

[0035] For example, if the value calculated by the controller is 40 mm, the value displayed on the monitor of the SCP large vehicle is 1, which proves that the SCP large vehicle has a 1-mm position offset in the running direction or the opposite direction of the running direction during the operation process. At this time, the emitting end of the laser sensor 6 is aligned with the top of the next step of the highest step in the identification boss 5.

[0036] Finally, if the value displayed on the monitor screen of the SCP large vehicle is within the allowable offset range and the SCP large vehicle can accurately push the processed coal cake into the carbonization chamber smoothly, it proves that the code plate 2 is accurately positioned. At this time, there is no need to adjust the connection position of the code plate 2 on the vertical part of the L-shaped fixing bracket 4; if the value displayed on the monitor screen of the SCP large vehicle exceeds the allowable offset range and the SCP large vehicle can still push the processed coal cake into the carbonization chamber, it proves that the code plate 2 is misaligned. At this time, the staff needs to horizontally move the code plate 2 through two kidney-shaped holes 22 to adjust the connection position of the code plate 2 on the vertical part of the L-shaped fixing bracket 4; if the value displayed on the monitor screen of the SCP large vehicle is within the allowable offset range and the SCP large vehicle cannot push the processed coal cake into the carbonization chamber, it proves that the code plate 2 is misaligned. At this time, the staff needs to horizontally move the code plate 2 through two kidney-shaped holes 22 to adjust the connection position of the code plate 2 on the vertical part of the L-shaped fixing bracket 4 to complete the further alignment of the SCP large vehicle.

[0037] Optionally, a positioning system for the SCP large vehicle further includes at least two identification bosses 7, and the two identification bosses 7 are oppositely arranged and are respectively fixedly connected to the two side surfaces of the bottommost step of the identification boss 5.

[0038] Specifically, the number of the identification bosses 7 in the present utility model is four, and two identification bosses 7 are respectively fixed on both side surfaces of the bottommost step of the identification boss 5.

[0039] In a specific embodiment, when two identification bosses 7 are respectively fixed on both side surfaces of the identification boss 5, during the operation of the SCP cart and the inverted U-shaped reading head 1, the controller activates the laser sensor 6, and the emitting end of the laser sensor 6 emits a light beam. When the SCP cart and the inverted U-shaped reading head 1 run to the furnace number area, the laser sensor 6 first measures the distance to the top end of the identification boss 7. If the controller calculates two sets of repeated data, it proves that the SCP cart has entered the area of the identification boss 5 at this time.

[0040] Due to the working environment of the SCP cart, particles of different sizes are likely to adhere to the surface of the code plate 2. By providing the identification bosses 7, it can better enable the controller to determine whether the position aligned with the emitting end of the laser sensor 6 is the top end of the identification boss 5, avoiding the situation of misalignment of the laser sensor 6 and incorrect data reading by the controller; and when the SCP cart has a position offset, if two sets of repeated data appear in the values calculated by the controller, it proves that the offset value of the SCP cart has exceeded the allowable offset range at this time, which can better enable the controller to judge the offset situation of the SCP cart; the identification bosses 7 can also enable the controller to enter the calculation program of the distance between the emitting end of the laser sensor 6 and the identification boss 5 in advance, improving the response sensitivity of the controller.

[0041] Optionally, each of the identification bosses 7 includes a low boss 72 and a high boss 71 connected to each other, and the distance between the low boss 72 and the identification boss 5 is less than the distance between the high boss 71 and the identification boss 5; the height of the high boss 71 is 3 mm, and the height of the low boss 72 is 2 mm.

[0042] Specifically, in the present utility model, the first identification boss 7 and the second identification boss 7 are both located on one side of the identification boss 5, and the third identification boss 7 and the fourth identification boss 7 are both located on the other side of the identification boss 5. The specific connection method is as follows: One side surface of the low boss 72 in the first identification boss 7 is fixedly connected to one side surface of the high boss 71 in the first identification boss 7, and the other side surface of the low boss 72 in the first identification boss 7 is fixedly connected to the other side surface of the bottommost step of the identification boss 5; One side surface of the low boss 72 in the second identification boss 7 is fixedly connected to one side surface of the high boss 71 in the second identification boss 7, and the other side surface of the low boss 72 in the second identification boss 7 is fixedly connected to the other side surface of the high boss 71 in the first identification boss 7; The connection method of the low boss 72 and the high boss 71 in the third identification boss 7 and the fourth identification boss 7 is the same as that of the low boss 72 and the high boss 71 in the first identification boss 7 and the second identification boss 7, and no detailed description will be given here.

[0043] Further, in the present utility model, when the SCP large vehicle and the inverted U-shaped reading head 1 run to the furnace number area, when the distances between the emission end of the laser sensor 6 and the tops of the identification bosses 7 are 47 mm, 48 mm, 47 mm, and 48 mm respectively, it is proved that the SCP large vehicle has entered the range of the identification boss 5 at this time.

[0044] Due to the long-term operation of the SCP large vehicle, it is easy to change the measurement distance between the code plate 2 fixed on the L-shaped fixing bracket 4 and the emission end of the laser sensor 6 on the inverted U-shaped reading head 1. By setting the identification boss 7, the distance between the code plate 2 and the emission end of the laser sensor 6 can be judged, and the zero distance can also be corrected.

[0045] For example, in the present utility model, the measurement distance between the code plate 2 and the emission end of the laser sensor 6 is 50 mm, the original zero distance between the emission end of the laser sensor 6 and the identification boss 5 is 39 mm, the distance between the emission end of the laser sensor 6 and the low boss 72 is 48 mm, and the distance between the emission end of the laser sensor 6 and the high boss 71 is 47 mm; When the distances between the emission end of the laser sensor 6 and the tops of the identification bosses 7 are 46 mm, 47 mm, 46 mm, and 47 mm respectively, at this time, the controller can judge that the measurement distance between the code plate 2 and the emission end of the laser sensor 6 is 49 mm. Therefore, the controller should shorten 1 mm on the basis of the original zero distance as the new zero distance between the emission end of the laser sensor 6 and the identification boss 5. When the distance measured by the laser sensor 6 between it and the identification boss 5 is 38 mm, the value displayed on the monitoring screen of the SCP large vehicle controlled by the controller is 0.

[0046] Optionally, an alignment system for an SCP trolley further includes a plurality of indicator lights, and the plurality of indicator lights are all installed on the operating platform of the SCP trolley; the plurality of indicator lights are all electrically connected to the controller.

[0047] Specifically, the number of indicator lights in the present utility model is six.

[0048] In a specific embodiment, when the SCP trolley completes the preliminary alignment, a plurality of indicator lights light up, and when the offset value of the SCP trolley exceeds the allowable offset range, the plurality of indicator lights go out.

[0049] The plurality of indicator lights can prompt the staff that the SCP trolley has completed the preliminary alignment at this time, and pay attention to observing whether there is any position offset during the operation of the SCP trolley.

[0050] Optionally, the material of the L-shaped fixing bracket 4 is iron, and the material of the code plate 2 is stainless steel.

[0051] Optionally, a magnet 8 is fixed at the bottom of the identification boss 5, and the identification boss 5 is magnetically connected to the L-shaped fixing bracket 4 through the magnet 8.

[0052] The present utility model fixes a magnet 8 at the bottom of the identification boss 5 to achieve magnetic attraction fixation with the L-shaped fixing bracket 4.

[0053] Since there may be multiple inlets for pushing coal cakes into the carbonization chamber during the specific production process, it is necessary to set the corresponding number of code plates 2 and the corresponding number of identification bosses 5;

[0054] As an implementation manner, before the SCP trolley runs, the staff can first install the first identification boss 5. After further aligning the SCP trolley and determining the connection position of the first code plate 2 on the L-shaped fixing bracket 4, then fix the remaining identification bosses 5 on the L-shaped fixing bracket 4. In this implementation manner, there is easily a situation where the emission end of the laser sensor 6 cannot be aligned with the top of the highest step of the identification boss 5 after the preliminary alignment of the SCP trolley is completed. Therefore, the staff needs to adjust the position of the identification boss 5 so that the emission end of the laser sensor 6 is aligned with the top of the highest step of the identification boss 5.

[0055] As another implementation manner, after the SCP trolley completes the preliminary alignment, install the first identification boss 5 on the L-shaped fixing bracket 4. After further aligning the SCP trolley and determining the connection position of the first code plate 2 on the L-shaped fixing bracket 4, then fix the remaining identification bosses 5 on the L-shaped fixing bracket 4.

[0056] In summary, for the alignment system of the SCP large vehicle provided by the present utility model, by setting the identification boss 5 on the code plate 2, it can accurately read the position offset data of the SCP large vehicle when the SCP large vehicle performs operations such as tamping, coal loading, and coke pushing, improving the alignment accuracy of the SCP large vehicle; by setting the recognition boss 7, the controller can better judge whether the SCP large vehicle enters the area of the identification boss 5, avoiding the situation where the controller reads incorrect data due to the influence of particles of different sizes attached to the surface of the code plate 2.

[0057] The above description is only the preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
