Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of garbage grate, in particular to a self-detecting anti-derailing feeding grate and garbage incinerator. BACKGROUND

[0002] In people's daily life, a large amount of garbage will inevitably be produced, and incineration is one of the main ways to deal with garbage. The key equipment of a garbage incineration power plant is a garbage incineration feeding grate, which mainly functions to continuously and uniformly feed garbage into an incinerator. The existing feeding grate mainly relies on a driving system to push the grate to move back and forth on a guide rail, thereby completing the quantitative conveying of garbage.

[0003] However, the existing feeding grate is operated in a harsh environment of high-temperature corrosive gas and mechanical impact for a long time. The guide rail wheel is designed in a flat roller, which is prone to thermal deformation, uneven wear and material aging under the conditions of high temperature, corrosion and heavy load, resulting in a decrease in the adhesion of the wheel and the guide rail, and a risk of derailment. The flat roller design lacks effective lateral restraint capability and cannot prevent the grate from deviating laterally during operation. There is a lack of effective real-time monitoring means to determine the operating state of the feeding grate, and the angle change, balance deviation and track deviation degree during the operation of the grate cannot be detected in time. Only periodic manual inspection can be relied on, and fault early warning and preventive maintenance cannot be achieved. SUMMARY

[0004] The present application aims to provide a self-detecting anti-derailing feeding grate and garbage incinerator to solve the problems of the guide rail wheel being prone to thermal deformation, uneven wear and material aging, the risk of derailment, the lack of effective real-time monitoring means to determine the operating state of the feeding grate, and the inability to detect the angle change, balance deviation and track deviation degree during the operation of the grate in time.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a self-detecting anti-derailment feeding grate, comprising a grate body, a cover plate, and a feeding grate body. The cover plate is fixedly installed on the top of the grate body. Symmetrically arranged track wheels are fixedly installed inside the grate body, and guide rails are movably installed on the top of the track wheels. The feeding grate body is fixedly installed on the top of the guide rails. A detection component is fixedly installed inside the grate body and the feeding grate body. The detection component includes a first equipment mounting base, a laser receiving target, and a second equipment mounting base. A mounting base 1 is symmetrically arranged on the front and rear sides of the feeding grate body. A dual-axis tilt sensor is fixedly installed on the outside of the mounting base 1. The laser receiving target is fixedly installed on the inner side of the top of the guide rail. The laser receiving target is located on the front side of the feeding grate body. A mounting boss and a mounting base 2 are fixedly installed on the right side of the grate body. A laser emitter is fixedly installed inside the mounting base 2. A mounting base 3 is fixedly installed on the inner side of the mounting boss. An industrial camera is fixedly installed on the inner side of the mounting base 3.

[0006] Preferably, multiple equipment mounting bases are arranged horizontally and equidistantly on both the front and rear sides of the feeding grate body, and the number of dual-axis tilt sensors corresponds to the number of equipment mounting bases.

[0007] Preferably, the laser emitter is positioned horizontally toward the laser receiving target, and the laser emitter and the industrial camera are positioned on the same longitudinal horizontal plane.

[0008] Preferably, the industrial camera is positioned at an angle toward the feeding grate body.

[0009] Preferably, the track wheel includes multiple wheel seats that are fixedly installed at the bottom of the grate body and are arranged horizontally at equal intervals. Guide wheels are rotatably installed on the inner side of each of the multiple wheel seats, and the guide rail is movably engaged above the guide wheels.

[0010] Preferably, the guide wheel includes a wheel body, an inner rim is provided on the inner side of the wheel body, and a conical tread is provided on the outer side of the wheel body, with the arc-shaped tread located between the inner rim and the outer rim.

[0011] Preferably, the height of the outer rim is greater than that of the inner rim.

[0012] In addition, this application also provides a waste incinerator, including the self-detecting anti-derailment feeding grate as described above.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The tapered tread is set on the outside of the wheel body at an outward angle. If the feeding grate body shifts laterally, the tapered tread will generate an automatic self-correcting force. Even if the wheel body is slightly deformed, the tapered wheel body can still maintain effective contact with the guide rail. The inner rim of the wheel body always fits against the inner wall of the guide rail, forming a mechanical constraint to prevent the feeding grate body from derailing.

[0015] 2. The dual-axis tilt sensors symmetrically installed on the front and rear sides of the feeding grate body can detect the changes in the components of gravity on the X and Y axes. They can measure the front-to-back and left-to-right tilt angles of the feeding grate body in real time. When the feeding grate body tilts due to wear of the guide wheels, deformation of the guide rails, or uneven load, the multiple dual-axis tilt sensors installed at the front and rear can detect the angle change in time and output the corresponding electrical signal to the external control system to achieve monitoring.

[0016] 3. The laser emitter projects a red laser line above the guide rail, corresponding to the laser receiving target. An industrial camera captures images of the red laser line, the guide rail, and the laser receiving target from the side, which are then transmitted to an external control system. The images are detected using visual inspection, enabling real-time monitoring and evaluation of the operating status of the feeding grate. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This invention provides a technical solution: a self-detecting anti-derailment feeding grate, comprising a grate body 1, a cover plate 2, and a feeding grate body 3. The cover plate 2 is fixedly installed on the top of the grate body 1. Symmetrically arranged track wheels 4 are fixedly installed inside the grate body 1, and guide rails 5 are movably installed on the top of the track wheels 4. The feeding grate body 3 is fixedly installed on the top of the guide rails 5. A detection component 6 is fixedly installed inside the grate body 1 and the feeding grate body 3. The detection component 6 includes a first equipment mounting base 61, a laser receiving target 63, and a second equipment mounting base 65. The first equipment mounting base 61 is symmetrically arranged on the front and rear sides of the feeding grate body 3. A dual-axis tilt sensor 62 is fixedly installed on the outside of the first equipment mounting base 61. The laser receiving target 63 is located at the front end of the feeding grate body 3. A second equipment mounting base 65 is fixedly installed on the right side inside the grate body 1. The system includes a boss 64 and a second equipment mounting base 65. A laser emitter 66 is fixedly installed inside the second equipment mounting base 65. A third equipment mounting base 67 is fixedly installed inside the boss 64, and an industrial camera 68 is fixedly installed inside the third equipment mounting base 67. Dual-axis tilt sensors 62, symmetrically installed on both sides of the feeding grate body 3, can detect the changes in the X and Y axes of gravity, and measure the front-to-back and left-to-right tilt angles of the feeding grate body 3 in real time. Simultaneously, a red laser line is projected above the guide rail 5 by the laser emitter 66, corresponding to the laser receiving target 63. The industrial camera 68 captures images of the red laser line, guide rail 5, and laser receiving target 63 from the side, transmitting these images to an external control system for visual detection. This allows for real-time monitoring of the operating status of the feeding grate body 3, providing warnings and assessments.

[0025] When the feeding grate body 3 tilts abnormally or deviates from the track, the control system triggers an alarm. The cooperation between the laser emitter 66 and the laser receiving target 63 can also effectively detect whether there are foreign objects or wear on the surface of the guide rail 5, thereby further improving the safety and stability of the equipment operation.

[0026] Multiple equipment mounting bases 61 are horizontally and equidistantly arranged on both the front and rear sides of the feeding grate body 3. The number of dual-axis tilt sensors 62 corresponds to the number of equipment mounting bases 61. The multiple horizontally arranged equipment mounting bases 61 are all firmly connected to the feeding grate body 3 by bolts to ensure its stability during operation. The dual-axis tilt sensors 62 are tightly connected to the equipment mounting bases 61 through brackets to form an integral structure, improving the accuracy of detection. The distribution design of multiple equipment mounting bases 61 allows the dual-axis tilt sensors 62 to cover a larger monitoring range, effectively improving the detection accuracy.

[0027] Both the second equipment mounting base 65 and the third equipment mounting base 67 adopt cage-type optical mounting bases with angle adjustment function, which can be finely adjusted when the laser emitter 66 and the industrial camera 68 are misaligned after long-term use.

[0028] The laser emitter 66 is horizontally positioned towards the laser receiving target 63. The laser emitter 66 and the industrial camera 68 are located on the same vertical horizontal plane, forming a straight optical path between the laser receiving target 63 and the laser emitter 66. This optical path can accurately detect the state of the guide rail 5 surface. The position of the industrial camera 68 is precisely calculated to ensure that its shooting range coincides with the optical path of the laser emitter 66. It can capture images of the laser emitter 66, the guide rail 5, and the laser receiving target 63 for real-time monitoring. When the red laser beam is blocked or deflected, the industrial camera 68 captures an image and, in conjunction with visual inspection, can quickly capture this change, improving detection efficiency, significantly reducing the workload of manual inspection, and ensuring the reliability and timeliness of the detection results.

[0029] The industrial camera 68 is angled toward the feeding grate body 3 to ensure that it can capture the entire view of the laser transmitter 66, the guide rail 5 and the laser receiving target 63, effectively guaranteeing the overall stability of the monitoring.

[0030] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 The track wheel 4 includes multiple wheel seats 41 that are fixedly installed at the bottom of the grate body 1 and are arranged horizontally at equal intervals. Guide wheels 42 are rotatably installed on the inner side of each wheel seat 41. The guide rail 5 is movably engaged above the guide wheel 42. The design of the guide wheel 42 can effectively reduce the friction of the guide rail 5 and ensure that the grate body 1 remains stable during operation. The horizontally equidistant distribution of multiple wheel seats 41 further enhances the stability of the overall structure and avoids deviation or jamming caused by uneven local force.

[0031] The guide wheel 42 includes a wheel body 421. An inner wheel rim 422 and an outer wheel rim 424 are respectively provided on both sides of the wheel body 421. An arc-shaped tread surface 423 is provided on the outside of the wheel body 421. The arc-shaped tread surface 423 is located on the outside of the wheel body 421 and is located on the inner wheel rim 422 and the outer wheel rim 424. Moreover, the height of the outer wheel rim 424 is slightly greater than that of the inner wheel rim 422.

[0032] Because the wheel body 421 has an inner rim 422 and an outer rim 424 on both sides, and the wheel body 421 has an arc-shaped tread surface 423 on the outside, the wheel body and the guide rail can be better matched and it is not easy to derail. When the grate body 3 shifts laterally, the arc-shaped tread surface 423 will generate an automatic return force. Even if the wheel body 421 is slightly deformed, the arc-shaped wheel body 421 can still maintain effective contact with the guide rail 5. The inner rim 422 on the inner side of the wheel body 421 always fits against the inner wall of the guide rail 5, and the outer rim 424 on the outer side always fits against the outer wall of the guide rail 5, forming a mechanical constraint to prevent the grate body 3 from derailing.

[0033] Working principle: During use, the drive system drives the guide rail 5 to slide and reset the feeding grate body 3 on the track wheel 4. The wheel body 421 has an arc-shaped tread surface 423 on its outside. When the feeding grate body 3 shifts laterally, the arc-shaped tread surface 423 will generate an automatic return force. Even if the wheel body 421 is slightly deformed, the arc-shaped wheel body 421 can still maintain effective contact with the guide rail 5. The inner wheel rim 422 on the inner side of the wheel body 421 always fits against the inner wall of the guide rail 5, and the outer wheel rim 424 on the outer side always fits against the outer wall of the guide rail 5, forming a mechanical constraint to prevent the feeding grate body 3 from derailing.

[0034] The dual-axis tilt sensors 62, which are fixed externally to the equipment mounting bases 61 symmetrically installed on the front and rear sides of the feeding grate body 3, can detect the changes in the components of gravity in the horizontal X and Y axes. They can measure the front-to-back and left-to-right tilt angles of the feeding grate body 3 in real time. When the feeding grate body 3 tilts due to wear of the guide wheel 42, deformation of the guide rail 5, or uneven load, the multiple dual-axis tilt sensors 62 set at the front and rear can detect the angle change in time and output the corresponding electrical signal to the external control system for timely reminder.

[0035] During operation, a laser beam is emitted simultaneously through a laser emitter 66 located inside the grate body 1 and horizontally positioned with the laser receiving target 63. A red laser line is projected above the guide rail 5, directly hitting the center of the laser receiving target 63. An industrial camera 68 can capture images of the red laser line, the guide rail 5, and the laser receiving target 63 from the side and transmit them to an external control system. When the feeding grate body 3 shifts position, the position of the red laser line in the image will change accordingly, and its position on the laser receiving target 63 will shift. By using visual inspection to detect the images, the operating status of the feeding grate body 3 can be reflected in a timely manner. The above is the working process of the entire device. Any content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0036] In some embodiments, this application also provides a waste incinerator (not shown) that includes a self-detecting anti-derailment feeding grate as described above.
