Description

Technical Field

[0001] This invention relates to the field of steel belt elevator technology, and in particular to a steel belt elevator and control system with anti-slip function. Background Technology

[0002] With the acceleration of urbanization, high-rise buildings (such as residential buildings, office buildings, and commercial complexes) have become the mainstream form of urban space development. As a core piece of vertical transportation equipment, the safety, stability, and efficiency of elevators directly affect the travel experience and life safety of passengers. Compared with traditional wire rope elevators, steel belt elevators have significant advantages such as small footprint (traction system volume reduced by more than 30%), low operating noise (no-load noise ≤55dB), and high load-bearing efficiency (a single steel belt can bear more than 800kg) due to the use of high-strength, lightweight steel belts instead of wire ropes. They have been widely used in mid- to high-rise residential and commercial buildings. However, in the current steel belt elevator and control system with anti-slip function, the existing cleaning scrapers are mostly rigidly connected. During operation, the vibration caused by the fluctuation of the traction wheel speed of the steel belt will cause a "hard impact" between the scraper and the steel belt. At the same time, the scratches caused by the impact will damage the anti-slip coating on the surface of the steel belt, which will reduce the friction. Furthermore, the surface is prone to the adhesion of dust, oil stains (such as lubricating oil leakage from the traction system) and condensate from the elevator shaft, which will lead to slippage. Therefore, the above-mentioned technical problems need to be addressed. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a steel belt elevator and control system with anti-slip function.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a steel belt elevator and control system with anti-slip function, including a chassis, with support mechanisms installed on both sides of the top of the elevator shaft above the chassis by bolts, and anti-slip mechanisms installed on the inner side of each support mechanism, and a traction motor installed on the upper end of the support mechanism by supporting bolts, and a main unit installed on the other side of the traction motor.

[0005] Preferably, the support mechanism includes a fixing block that is bolted to the inner wall of the elevator shaft, an inverted U-shaped support bracket fixed to the upper end of the fixing block, and a fixing plate fixed to the upper end of the support bracket away from the fixing block, and the fixing plate having bolt holes on the inner side of the elevator shaft. The anti-slip mechanism includes an inverted T-shaped connecting block that is vertically fixed to the bottom of the support frame. A first cleaning scraper is hinged to the bottom of the connecting block, and a connecting plate is horizontally fixed to one side of the connecting block. A second cleaning scraper is hinged to one end of the connecting plate near the middle of the elevator shaft. Both the first cleaning scraper and the second cleaning scraper are equipped with a dirt removal component. The cleaning assembly includes a rotating platform. The first and second cleaning scrapers are rotatably connected to the rotating platform at the positions corresponding to the steel strips. Several telescopic scrapers are installed on the outer wall of the rotating platform. A scraper box is installed at the middle position of the two steel strips on the first and second cleaning scrapers. Horizontal scrapers are slidably connected to both sides of the scraper box. A dirt-scraping frame is also provided on the first and second cleaning scrapers at the positions corresponding to the horizontal scrapers.

[0006] Preferably, a positioning plate is installed above the fixing plate by fixing bolts, and the positioning plate is threadedly connected to one side of the traction motor by bolts.

[0007] Preferably, the output end of the traction motor is provided with multiple steel strips that are equidistantly arranged downwards and vertically, and the steel strips all pass through the top control box above the chassis. The chassis is equipped with a protective frame.

[0008] Preferably, a support seat for supporting the output end of the traction motor is vertically fixed to the middle of the support frame below the middle of the output end of the traction motor.

[0009] Preferably, a fixing plate is provided at the upper center of the second cleaning scraper and the first cleaning scraper. One end of the fixing plate is fixedly connected to the connecting block. Two telescopic springs are equidistantly arranged at the lower end of the fixing plate. The two telescopic springs are respectively installed in the fixing cylinders at the upper end of the first cleaning scraper and the second cleaning scraper. One end of the two telescopic springs is fixedly connected to the first cleaning scraper and the second cleaning scraper, respectively, and the other end is fixedly connected to the fixing plate.

[0010] Preferably, the control system includes an intelligent control component, and the intelligent control component includes an analysis module; The analysis module receives the acquired impurity image data, performs outlier analysis, and filters out images for analysis. It then performs image analysis on the analyzed images; if the number of impurity image blocks in the analyzed image exceeds a preset threshold, a cleanup signal is generated and transmitted to the control module. The module analyzes the time interval data for generating the cleanup signal; if the time interval difference is greater than a preset time difference threshold, a sudden warning signal is generated and transmitted to the control module; otherwise, a warning count is performed, and when the warning count reaches a preset threshold, a cumulative warning signal is generated and transmitted to the control module.

[0011] Preferably, the analysis module performs the following steps to analyze the image: M1: Acquire a1 image data at the same time, calculate the mean A1 and standard deviation B of the gray values ​​of the corresponding numbered image blocks in the a1 images, and set the gray value data fluctuation range [A1-3B, A1+3B] based on the calculated mean A1 and standard deviation B, compare the gray value data with the gray value data fluctuation range, mark the gray value data outside the fluctuation range as outliers, and record the number of outliers a2; M2: If a2 > 30% * a1, the collected data is determined to be abnormal, and the data is re-detected; if a2 ≤ 30% * a1, the outliers are removed, the mean A2 is calculated for the remaining grayscale data after removing the outliers, and the image block with the closest grayscale value is marked. After marking all numbered image blocks, the image with the most marks is selected for analysis.

[0012] Preferably, the analysis module performs the time interval analysis steps as follows: N1: Record the interval time for generating the cleanup signal. If the interval time for generating the nth cleanup signal is t... n <t n-1 And t n-1 -t n <△t s Then, perform an early warning count, t n-1 Δt is the interval between the (n-1)th generation of the cleanup signal. s The preset time difference threshold; N2: If t n-1 -t n ≥△t s If the alarm count reaches a preset threshold, a sudden early warning signal is generated and transmitted to the control module. When the alarm count reaches a preset threshold, a cumulative early warning signal is generated and transmitted to the control module.

[0013] Compared with the prior art, the beneficial effects of the present invention are: By using the telescopic spring in conjunction with the first cleaning scraper, the second cleaning scraper, and the fixing plate, the impact force can be reduced through elastic deformation, improving the buffering effect of the scraper contacting the steel strip. This protects the anti-slip coating on the steel strip from scratches and maintains the original friction of the anti-slip coating. Furthermore, the cooperation between the first and second cleaning scrapers facilitates the removal of adhering dust and oil, improving the cleanliness of the steel strip surface. This eliminates the impact of impurities on the friction of the steel strip, ultimately solving the problem of rigid connections damaging the anti-slip coating and reducing friction due to accumulated impurities. By using a rotating table and telescopic scraper for horizontal cleaning, and a scraper box and horizontal scraper for vertical cleaning, the problem of "impurities accumulating and causing steel belt shifting and reduced contact area" is avoided. This ensures that the friction between the steel belt and the traction sheave is always maintained at a safe threshold, reducing the risk of slippage at its source. The "automatic scraping off of impurities" when the telescopic scraper retracts, and the "instant decontamination" in conjunction with the horizontal scraper and the scraping frame, eliminate the need for manual disassembly of the cleaning components, reducing the workload of maintenance personnel. At the same time, it prevents impurities from accumulating on the components and causing secondary contamination of the steel belt, reducing the risk of repeated slippage due to "incomplete cleaning", and extending the service life of the steel belt and cleaning components. By comparing grayscale values ​​and filtering outliers, the system accurately determines the number of impurity image blocks and initiates cleaning only when the number exceeds a threshold. This avoids component wear and increased energy consumption caused by frequent cleaning even when impurities do not reach the risk threshold, and also prevents slippage accidents caused by excessive impurities that are not cleaned. In the event of a sudden surge in impurities, the control module can immediately perform operations such as speed reduction and temporary stopping after receiving an emergency warning, reducing friction loss between the steel belt and the traction sheave, preventing slippage caused by a sudden drop in friction in a short period of time, and ensuring passenger safety. In the event of a slow deterioration of impurities, cumulative warnings can remind maintenance personnel to investigate the root cause of the problem, avoiding component damage caused by neglecting minor issues for a long time. At the same time, by intervening in advance, the system reduces elevator downtime caused by equipment failure, improving the reliability of elevator operation and the user travel experience.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] Example 1: See Figures 1 to 5 This invention discloses a steel belt elevator and control system with anti-slip function, comprising a chassis 1. Support mechanisms are bolted to both sides of the top of the elevator shaft above the chassis 1. Anti-slip mechanisms are installed inside each support mechanism. A traction motor 10 is mounted on the upper end of the support mechanism via supporting bolts. A main unit 9 is mounted on the other side of the traction motor 10. The chassis 1, support mechanisms, anti-slip mechanisms, traction motor 10, and main unit 9 facilitate the construction of an overall frame for the steel belt elevator with anti-slip function, providing installation support for the traction motor and main unit 9. Simultaneously, the anti-slip mechanism ensures the anti-slip safety of the elevator during operation. Furthermore, an coded sensor on one side of the main unit 9 facilitates comparison with pulses inside the main unit 9, thereby preventing slippage due to the steel belt. Slippage leads to continuous friction; the support mechanism includes a fixing block 3 bolted to the inner wall of the elevator shaft, an inverted U-shaped support bracket 4 fixed to the upper end of the fixing block 3, and a fixing plate 5 fixed to the upper end of the support bracket 4 away from the fixing block 3. The fixing plate 5 has bolt holes on the inner side of the elevator shaft. The fixing block 3, support bracket 4, and fixing plate 5 facilitate the formation of a stable support structure for key elevator components, providing a solid bearing foundation for the installation of subsequent components; a positioning plate 13 is installed above the fixing plate 5 by fixing bolts. The positioning plate 13 is threaded to one side of the traction motor 10 by bolts. The positioning plate 13 and fixing bolts facilitate the stable fixing of the traction motor 10 to the support mechanism, preventing the traction motor from shifting during operation and ensuring its operational stability.

[0018] In this invention, multiple steel belts are vertically and equidistantly arranged downwards at the output end of the traction motor 10. These steel belts all pass through the top control box above the chassis 1. A protective frame 2 is installed on the chassis 1. The steel belts and protective frame 2 facilitate the lifting and lowering of the chassis 1 to achieve elevator operation. Simultaneously, the protective frame 2 provides safety protection during maintenance of the top of the chassis 1. A support seat for supporting the output end of the traction motor 10 is vertically fixed upwards at the center of the support frame 4 below the middle of the output end of the traction motor 10. This support seat provides auxiliary support to the output end of the traction motor 10, reducing the load on the output end, preventing component deformation or damage due to long-term operation, and extending the service life of the traction motor. The anti-slip mechanism includes an inverted T-shaped connecting block 6 vertically fixed downwards below the support frame 4. A first cleaning scraper 7 is hinged below the connecting block 6 and connected to... A connecting plate is horizontally fixed to one side of block 6. A second cleaning scraper 8 is hinged to one end of the connecting plate near the middle of the elevator shaft. A fixing plate 11 is set above the second cleaning scraper 8 and the first cleaning scraper 7 in the middle. One end of the fixing plate 11 is fixed to the connecting block 6. Two telescopic springs 12 are equidistantly arranged at the lower end of the fixing plate 11. The two telescopic springs 12 are respectively installed in the fixing cylinders at the upper ends of the first cleaning scraper 7 and the second cleaning scraper 8. One end of the two telescopic springs 12 is fixed to the first cleaning scraper 7 and the second cleaning scraper 8 respectively, and the other end is fixed to the fixing plate 11. Through the connecting block 6, the first cleaning scraper 7, the second cleaning scraper 8, the fixing plate 11, and the telescopic springs 12, it is convenient to use the cleaning scraper to remove impurities on the steel belt. At the same time, the telescopic springs 12 ensure that the scraper and the steel belt are in close contact, reducing the risk of steel belt slippage caused by impurities and ensuring the safe operation of the elevator.

[0019] Working Principle: In the use of this invention, the fixing block 3 is first fixed to the inner wall of the elevator shaft using expansion screws. Simultaneously, the support seat and positioning plate 13 facilitate the fixing of the traction motor 10. Then, after the traction motor 10 is powered on and started, its output end drives the traction sheave to rotate. The traction sheave drives multiple steel belts to run vertically through friction. Simultaneously, the steel belts pass through the top control box above the elevator car 1, thus rigidly connecting to the car 1. Therefore, the raising and lowering of the steel belts can synchronously raise and lower the car 1, realizing the elevator's up and down movement. At the same time, the main unit 9 is electrically connected to the traction motor 10, and controls the traction motor 10 through a preset program or external commands. The traction motor 10 is adjusted so that when the elevator reaches the target floor, the main unit 9 controls the traction motor 10 to decelerate and stop. The steel belt drives the chassis 1 to stop precisely. At the same time, when the traction motor 10 drives the steel belt to run vertically, the first cleaning scraper 7, under the elastic force of the telescopic spring 12, always maintains a certain distance from the outer surface of the steel belt. This allows for the scraping of thicker oil stains and larger debris adhering to the surface of the steel belt. Furthermore, the first cleaning scraper 7 and the second cleaning scraper 8 prevent impurities from causing the steel belt to deviate during operation, ensuring a stable contact area between the steel belt and the traction wheel, and further guaranteeing friction.

[0020] Example 2: See Figure 6 and Figure 7 Unlike Embodiment 1, the first cleaning scraper 7 and the second cleaning scraper 8 are installed in an alternating vertical structure, and both the first cleaning scraper 7 and the second cleaning scraper 8 are equipped with a dirt removal component. The cleaning assembly includes a rotating table 14. The first cleaning scraper 7 and the second cleaning scraper 8 are each rotatably connected to the rotating table 14 at positions corresponding to the steel strips. Several telescopic scrapers 15 are installed on the outer wall of the rotating table 14. Adjusting springs are installed inside the rotating table 14 at positions corresponding to the telescopic scrapers 15, and adjusting push rods are also installed inside the rotating table 14 at positions corresponding to the adjusting springs. The two ends of the adjusting springs are connected to the telescopic scrapers 15 and the adjusting springs, respectively. The adjusting push rods control the extension length of the telescopic scrapers 15 by controlling their own length changes. When the adjusting push rod controls the telescopic scrapers 15 to extend, the exposed end of the telescopic scraper 15 contacts the first cleaning scraper 7 or the second cleaning scraper 8 and they press against each other, causing the telescopic scrapers 15 to retract inwards, thus deforming the adjusting springs. When the adjusting push rod controls the telescopic scrapers 15 to retract, the exposed end of the telescopic scrapers 15 is completely closed. The material attached to the exposed end of the scraper is scraped off when the telescopic scraper 15 extends again. A scraper box 16 is installed at the middle position of the two steel strips on the first cleaning scraper 7 and the second cleaning scraper 8. Horizontal scrapers 17 are slidably connected to both sides of the scraper box 16. A telescopic rod is set inside the scraper box 16 at the position corresponding to the horizontal scraper 17. The telescopic rod controls the horizontal scraper 17 to extend and retract repeatedly to clean the stains scraped off by the steel strips on the first cleaning scraper 7 or the second cleaning scraper 8. A scraping frame 18 is also set on the first cleaning scraper 7 and the second cleaning scraper 8 at the position corresponding to the horizontal scraper 17. The horizontal scraper 17 is in close contact with the scraping frame 18. When the horizontal scraper 17 reciprocates and extends, the material attached to the horizontal scraper 17 is scraped off and carried away when the horizontal scraper 17 extends again. The control system includes intelligent control components, which include an analysis module and a control module. The analysis module receives the acquired impurity image data, performs outlier analysis, and filters out images for analysis. It then performs image analysis on the analyzed images; if the number of impurity image blocks in the analyzed image exceeds a preset threshold, a cleanup signal is generated and transmitted to the control module. The module analyzes the time interval data for generating the cleanup signal; if the time interval difference is greater than a preset time difference threshold, a sudden warning signal is generated and transmitted to the control module; otherwise, a warning count is performed, and when the warning count reaches a preset threshold, a cumulative warning signal is generated and transmitted to the control module. The camera installed on the first cleaning scraper 7 and the second cleaning scraper 8 acquires image data of the impurities scraped off the first cleaning scraper 7 and the second cleaning scraper 8; the acquired image data is processed in grayscale and divided according to the size of the pixel block, and then numbered according to the number of rows and columns of the divided image block in the whole image; At the same time, acquire a1 image data. Calculate the mean A1 and standard deviation B of the grayscale values ​​of the corresponding numbered image blocks in the a1 images. Set the grayscale value data fluctuation range [A1-3B, A1+3B] based on the calculated mean A1 and standard deviation B. Compare the grayscale data with the fluctuation range of the grayscale value data. Mark grayscale values ​​outside the fluctuation range as outliers and record the number of outliers a2. If a2 > 30% * a1, the acquired data is determined to be abnormal, and the data detection is repeated. If a2 ≤ 30% * a1, the outliers are removed. Calculate the mean A2 of the remaining grayscale data after removing outliers. Mark the image block with the closest grayscale value. After marking all numbered image blocks, select the image with the most marks as the analysis image.

[0021] The entire image only includes the scraping operation of the first cleaning scraper 7 and the second cleaning scraper 8 on the steel strip. The gray value of the corresponding numbered image block is compared with the preset gray value of the steel strip and the gray value of the cleaning component. If the gray value of the image block is not within the gray value range of either, it is determined to be an image block with impurities. The number of impurity image blocks C1 is counted. When C1 ≥ C max When impurities accumulate, a cleaning signal is generated and transmitted to the control module, C. max The preset threshold for the number of image blocks; After receiving the cleaning signal, the control module controls the drive structure of the rotary table 14 to rotate, so that the telescopic scraper 15 on the rotary table 14 scrapes away impurities in the horizontal direction on the first cleaning scraper 7 or the second cleaning scraper 8; it controls the telescopic rod inside the scraper box 16 to extend and retract, so that the horizontal scraper 17 scrapes away impurities in the vertical direction on the first cleaning scraper 7 or the second cleaning scraper 8. The telescopic rod controls the horizontal scraper 17 to perform scraping operations within the rotation gap of the telescopic scraper 15, and the two do not affect each other.

[0022] The interval between generating cleanup signals is recorded. If the interval between the nth cleanup signal generation is t... n <t n-1 And t n-1 -t n <△t s Then, perform an early warning count, t n-1 Δt is the interval between the (n-1)th generation of the cleanup signal. s The preset time difference threshold; if t n-1-t n ≥△t s If the alarm count reaches a preset threshold, a sudden early warning signal is generated and transmitted to the control module. When the alarm count reaches a preset threshold, a cumulative early warning signal is generated and transmitted to the control module.

[0023] After receiving a sudden warning signal, the control module sends a speed reduction command to the traction motor 10, reducing the elevator's operating speed to 60% to 70% of the normal speed. This reduces the relative friction frequency between the steel belt and the traction sheave, and reduces the continuous weakening effect of impurities on friction. The coded sensor of the linkage host 9 and the laser speed sensor at the lower end of the steel belt compare the output speed of the traction motor with the actual operating speed of the steel belt once per second. If the speed difference exceeds 8% (indicating that the friction has decreased significantly and is close to the slippage threshold), a "temporary stop command" is immediately sent to the elevator control system to control the elevator to stop at the nearest floor to evacuate passengers and switch to "maintenance mode" to prevent slippage accidents during passenger operation. After receiving the cumulative warning signal, the control module sends a "component detection command" to the host 9 to obtain data such as the wear degree of the traction sheave (wear > 0.5mm will weaken the friction), the pressure of the lubricating oil pipeline (too low pressure may lead to increased leakage), and the torque of the support seat bolts (torque deviation > 10N·m will cause the traction sheave to shift, reducing the contact area with the steel belt). If an abnormality is found, a "faulty component list" is generated and pushed to the operation and maintenance platform, requiring replacement or repair within a time limit to eliminate the risk of slippage caused by the continuous generation of impurities from the root.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
