Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spiral conveying detection, and particularly to a nanoceramic layer spiral conveying device with a wear detection mechanism. BACKGROUND

[0002] The spiral conveyor is a key equipment for conveying powdery, granular and small block abrasive materials in the mining, metallurgy, building material and chemical industries. In order to resist strong material abrasion, a high-hardness wear-resistant coating such as a nanoceramic layer is often applied to the working surface of the spiral blade. However, the wear-resistant layer will still gradually wear out under long-term extreme working conditions, and even locally peel off or crack due to impact and fatigue. Once local damage occurs, the base material will be exposed and quickly worn out, resulting in equipment failure, causing unplanned shutdown and huge economic losses. Therefore, timely and accurate online monitoring of the state of the wear-resistant layer, especially early identification of local damage, is a core requirement for realizing predictive maintenance and ensuring long-period safe operation of the equipment.

[0003] At present, the detection of the wear-resistant layer of the spiral conveying device in the prior art mainly has three common defects in terms of efficiency, coverage and precision distortion, which are as follows: Neither the manual method which needs to interrupt production and can only sample and detect, nor the fixed online monitoring which can only obtain static single-point data, can realize continuous and global morphology scanning of the entire blade working surface, so that local damage is easily missed; The pre-embedded sacrificial unit method cannot reflect the real surface morphology and may introduce structural weak points due to the nature of indirect measurement and average estimation; The fundamental limitation of these methods is the contradiction between the static and discrete characteristics of the detection device and the dynamic and continuous working surface of the blade, which leads to one-sided monitoring data and insufficient reliability, making it difficult to support accurate predictive maintenance.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0020] The implementation of the present application is described in detail below in combination with specific embodiments.

[0021] In the embodiment: Reference Figure 1The application provides a preferred embodiment.

[0022] The nanoceramic layer spiral conveying device with a wear detection mechanism comprises a rack 1, a driving motor 11, a conveying screw 12 rotated by the driving motor 11, and further comprises: a detection track device 2 erected in parallel above the rack 1, and a detection mechanism 3 installed in the detection track device 2 and capable of reciprocating along the detection track device 2, the detection track device 2 serving as a running carrier of the detection mechanism 3, and the length of the detection track device 2 is generally matched with the conveying section of the conveying screw 12.

[0023] The detection mechanism 3 comprises: a detection trolley 31 movably arranged on the detection track device 2; a pushing assembly 32 arranged on the detection trolley 31, and used for interacting with the blades of the conveying screw 12 to drive the detection trolley 31 to run in a first direction of the detection track device 2 when the conveying screw 12 rotates; a detection assembly 34 arranged on the detection trolley 31, comprising a vertically telescopic measuring cylinder 341 and a probe 343 arranged at the lower end of the measuring cylinder 341, and the probe 343 is kept in contact with the surface of the blades of the conveying screw 12 during the running of the detection trolley 31; and an adjusting assembly 33 arranged on the detection trolley 31, used for adjusting the abutting position of the probe 343 and the blades of the conveying screw 12, and capable of triggering the probe 343 to retract and reset when the detection trolley 31 runs to the end of the detection track device 2.

[0024] Specifically, the detection track device 2 is a box-shaped structure, and the inside of the detection track device 2 is divided into side-by-side downward channels 211 and upward channels 212 by guide rails 21 arranged on the two inner walls, thereby constructing a closed circulation path for the detection trolley 31; The end of the guide rail 21 is connected with a deflectable reversing guide plate 22 through a spring shaft; The two sides of the detection trolley 31 are provided with guide wheels 311 in rolling cooperation with the guide rail 21.

[0025] The reversing guide plate 22 keeps a posture inclined to the downward channel 211 under the action of the internal spring shaft in a natural state (i.e. without external force), which enables the detection trolley 31 to rely on inertia to push open the reversing guide plate 22 and smoothly reverse under the guidance of the reversing guide plate 22 when running to the end of the downward channel 211, thereby completing the automatic conversion of the running direction.

[0026] The pushing assembly 32 is responsible for converting the mechanical energy of rotating the conveying screw 12 into the kinetic energy of advancing the detection trolley 31, which includes an abutting rod 321 arranged on the detection trolley 31, the abutting rod 321 extending to the blade pushing side of the conveying screw 12 and abutting with the blade surface; the end of the abutting rod 321 is provided with two abutting wheels 322 for rolling contact with the blade surface. The abutting rod 321 between the two abutting wheels 322 is also provided with an air nozzle 323. When the conveying screw 12 rotates, the side surface of the blade will continuously push the abutting rod 321, thereby driving the entire detection trolley 31 to travel along the detection rail device 2 (specifically the downward passage 211); in order to reduce sliding friction, avoid scratching the ceramic layer, and adapt to the slight unevenness of the blade surface, two abutting wheels 322 are arranged at the end of the abutting rod 321, the abutting wheels 322 are staggered, can ensure the fit according to the curvature of the blade surface, and the two abutting wheels 322 form rolling contact with the blade surface to reduce friction resistance and wear; Further, in order to solve the problem of material accumulation or adhesion in front of the probe 343 during the detection process, the abutting rod 321 is also provided with an air nozzle 323 between the two abutting wheels 322, the air nozzle 323 is connected to an external air source through a hose, and can blow out compressed air to sweep out a clean detection area instantaneously before the probe 343 contacts the blade surface, ensuring the accuracy of detection.

[0027] The detection assembly 34 is a direct component for performing wear measurement, including a detection rod 342 which is pivotally installed inside the measuring cylinder 341, and the probe 343 is connected to the lower end of the detection rod 342; While the detection trolley 31 is driven by the pushing assembly 32 to move axially along the conveying screw 12, the probe 343 is always in contact with the rotating spiral blade surface under the control of the adjusting assembly 33; since the spiral blade is rotating and the detection trolley 31 is moving axially, the contact track of the probe 343 actually covers a spiral belt-shaped area of the blade working surface, realizing continuous linear scanning of the specified ring belt of the blade surface; the detection rod 342 deflects with the displacement of the probe 343 due to the ups and downs of the blade surface, when the probe 343 is displaced due to the ups and downs of the wear pits of the blade surface, ceramic layer peeling, etc., the detection rod 342 will be driven to deflect around its shaft accordingly.

[0028] In order to accurately convert the mechanical deflection angle of the detection rod 342 into an electrical signal that can be recognized by the control system, the detection assembly 34 further includes a signal conversion module, which includes a conductive contact 346 arranged at the upper end of the detection rod 342, and a plurality of independent current-carrying pieces 347 arranged along the deflection fan-shaped path of the conductive contact 346; The conductive contact 346 is in contact with different positions of the electrified sheet 347 when the detection rod 342 is deflected, so as to convert the deflection angle of the detection rod 342 into different electrical signals. Each electrified sheet 347 is connected to a different signal line. When the blade surface is flat, the detection rod 342 is in a neutral position, and the conductive contact 346 is in contact with the middle electrified sheet 347. When the probe 343 encounters a depression or protrusion, the detection rod 342 is deflected, and the conductive contact 346 is in contact with the electrified sheet 347 at a different position, thereby outputting different circuit on-off signals. The control system can infer the displacement amount of the probe 343 by identifying which electrified sheet 347 is turned on, and then judge the wear or damage depth of the contact point. The analog displacement is converted into a digital gear signal, which has strong anti-interference ability and is convenient to process.

[0029] In addition, one side of the measuring cylinder 341 is provided with an electromagnetic element 344, and one side of the upper end of the detection rod 342 is provided with an armature 348 corresponding to the magnetic attraction part of the electromagnetic element 344. A contact spring 345 is further sleeved between the electromagnetic element 344 and the armature 348. In order to ensure the stability of the detection rod 342 in the non-detection state and provide an adjustable initial contact force, an electromagnetic element 344 (electromagnet) is arranged on the inner wall of one side of the measuring cylinder 341, and an armature 348 is arranged at the corresponding position of the upper end of the detection rod 342. A contact spring 345 is sleeved between the electromagnetic element 344 and the armature 348. During operation, the magnetic force of the electromagnetic element 344 on the armature 348 can be changed by controlling the current, so as to adjust the initial posture of the detection rod 342 and the contact pre-pressure of the probe 343 together with the elastic force of the contact spring 345, so that it can be reliably contacted, and will not accelerate wear or damage the ceramic layer due to excessive pressure.

[0030] A guide rod 312 is vertically arranged on the detection trolley 31, and the upper end of the measuring cylinder 341 is slidably sleeved outside the guide rod 312 through a sleeve ring. A contraction spring 313 is sleeved on the guide rod 312 and acts between the sleeve ring of the detection trolley 31 and the measuring cylinder 341, so as to provide an upward reset tendency for the measuring cylinder 341.

[0031] The adjusting assembly 33 is responsible for coordinating the measurement and reset actions of the detection assembly 34, which includes a trigger reset mechanism including a sleeve 331 arranged on the detection trolley 31, a pressure rod 332 slidably arranged in the sleeve 331, a support rod 333 connected to the inner side of the pressure rod 332, and a reset spring 334 arranged in the sleeve 331 and acting on the pressure rod 332. The pressure rod 332 slides inward when the detection trolley 31 travels to the end of the detection track device 2. The driving mechanism comprises a servo motor 336, an adjusting gear 337 driven by the servo motor 336, a toothed plate 3411 arranged on one side of the measuring cylinder 341 and engaged with the adjusting gear 337, and a connecting rod 335 connecting the supporting rod 333 and the servo motor 336; The trigger reset mechanism is used to sense whether the detection trolley 31 reaches the end of the track and to trigger the reset action. When the detection trolley 31 is pushed by the blade of the conveying screw 12 to the end of the detection track device 2, the end of the pressing rod 332 will hit the preset stopper or slope of the track end, and be pressed to slide into the sleeve 331, compressing the reset spring 334.

[0032] The driving mechanism is used to perform precise telescopic adjustment and rapid reset release. In the normal detection stroke, the servo motor 336 can be controlled to rotate, drive the adjusting gear 337 to engage with the toothed plate 3411 to transmit power, thereby precisely controlling the depth of the measuring cylinder 341 to probe the initial abutting position with the surface of the blade. When the trigger reset mechanism is triggered, i.e. the pressing rod 332 is pressed inward, the servo motor 336 and the adjusting gear 337 thereon are driven to produce a transverse displacement through the supporting rod 333 and the connecting rod 335, and the displacement is designed to be just enough to disengage the adjusting gear 337 from the toothed plate 3411. Once the engagement is released, the measuring cylinder 341 and the components connected thereto, such as the probe 343 and the detection rod 342, are no longer locked by the gear pair, and will be quickly pulled up under the powerful reset force of the contraction spring 313, realizing rapid contraction and reset, so that the probe 343 safely separates from the surface of the blade. This process is triggered by mechanical linkage, and the response is rapid and reliable, avoiding interference between the probe 343 and the blade of the conveying screw 12 when the detection trolley 31 enters the upward channel 212 and walks back.

[0033] Working principle: When the device is running, the driving motor 11 drives the conveying screw 12 to rotate and convey the material. At the same time, the rotating force of the blade of the conveying screw 12 is converted into the power for the detection trolley 31 to move forward along the downward channel 211 through the abutting rod 321 and the abutting wheel 322 of the pushing assembly 32. The probe 343 on the detection trolley 31 acts on the surface of the rotating blade with constant contact force under the control of the adjusting assembly 33. As the trolley moves axially slowly, the probe 343 essentially performs continuous scanning of a spiral line on the surface of the blade. The detection rod 342 converts the surface undulations sensed by the probe 343 into deflection, and generates a series of electrical signals representing the surface topography through the contact between the conductive contact 346 and different energized pieces 347. The signals are recorded and analyzed in real time, and the system can immediately alarm once abnormal fluctuations (corresponding to local damage) occur. When the detection trolley 31 completes a single detection and reaches the end, the pressure rod 332 is triggered, the adjusting gear 337 is disengaged through mechanical linkage, the measuring cylinder 341 and the probe 343 are instantaneously retracted under the action of the contraction spring 313, and the detection trolley 31 enters the upward passage 212 under the guidance of inertia and the reversing guide plate 22; in the upward passage 212, the trolley can return to the starting end by relying on gravity or an auxiliary traction device because the pushing assembly 32 loses the blade pushing force; after reaching the starting end, the adjusting assembly 33 controls the probe 343 to be lowered again, and the next detection cycle is started, realizing online, continuous and full-surface coverage contact type wear detection, completely solving the blind area problem of traditional single-point fixed detection, and being capable of sensitively identifying local damage, thereby providing a high-precision data basis for predictive maintenance.

[0034] The detection trolley 31 driven by the blade of the conveying screw 12 itself and running along the parallel track is arranged, so that the probe 343 mounted thereon can continuously contact and scan a complete spiral strip area of the surface of the rotating blade along with the axial movement of the trolley, which changes the mode of traditional fixed single-point detection, realizes linear continuous scanning without blind area on the working surface of the blade, can capture every abnormal point in the entire detected area, and obtains a continuous surface topography curve data instead of discrete point data, through trend analysis and abnormal fluctuation identification of the curve, not only the overall wear degree can be judged, but also the occurrence and development of local damage can be early warned, so that a precise predictive maintenance plan can be made, sudden failure can be avoided, and the equipment life and production continuity can be maximized.

[0035] The detection trolley 31 does not need an additional independent driving device, but directly uses the original power of the rotation of the conveying screw 12 as the driving power for running, which not only simplifies the system structure, reduces the cost and energy consumption, but also ensures the synchronization between the detection running speed and the helical pitch, so that the scanning track perfectly matches the helical line of the blade.

[0036] The air nozzle 323 is integrated on the abutting rod 321 of the pushing assembly 32, high-pressure airflow can be used to instantaneously sweep the detection point before the probe 343 contacts the surface of the blade, and the covered material is actively removed, so that the direct and reliable contact between the probe 343 and the surface of the ceramic layer is ensured, thereby ensuring the accuracy and stability of the detection data, and the application is especially suitable for the working conditions of high adhesion or easy accumulation of materials.

[0037] The signal conversion mechanism of the application combines mechanical lever (detection rod 342) with high-resolution electrical contact array (conductive contact 346 and current-carrying sheet 347), amplifies and converts the vertical displacement of the micro probe 343 (corresponding to the wear pit or peeling protrusion) into discrete electrical signal levels, is sensitive to local topography mutations, can accurately identify micro peeling, cracks and other local defects that cannot be found by traditional average measurement, and provides quantitative depth information.

[0038] The driving mechanism composed of the servo motor 336, the adjusting gear 337 and the toothed plate 3411 can accurately adjust the probe 343 down depth and contact pre-pressure, and the unique mechanical linkage type trigger reset mechanism can automatically trigger when the detection trolley 31 runs to the end of the track, so that the probe 343 quickly and reliably separates from the blade surface, and then the trolley automatically turns back under the guidance of the reversing guide plate 22, the whole process does not need manual intervention, realizes the full automation cycle of detection, reset and return, and is safe and reliable in operation.

[0039] The application organically combines dynamic following, contact scanning, active cleaning, high-sensitivity sensing and automatic reset, and fundamentally solves the technical problem that the wear-resistant layer state of the spiral conveying equipment is difficult to monitor online.

[0040] The above only describes the preferred embodiments of the application and is not used to limit the application, and any modification, equivalent replacement and improvement made within the spirit and principle of the application should be included in the protection scope of the application.
