Description

Technical Field

[0001] This utility model belongs to the field of hoisting technology, specifically relating to a large-angle hook hoisting machine that can achieve double-sided automatic cleaning. Background Technology

[0002] In material handling scenarios in industries such as food and building materials, traditional steep-angle elevators, relying on the structural design of corrugated sidewall conveyor belts and cross diaphragms, can stably transport materials at angles of 20° to 90° or even vertical, making them key equipment in industrial production. However, these elevators suffer from significant contamination issues during long-term operation. Dust, sticky residues, or lumpy materials easily accumulate on the surface of the conveyor belt, the inner side of the sidewalls, and the gaps in the cross diaphragms. If not cleaned promptly, these residues may mold or clump, contaminating subsequently transported materials. Existing cleaning methods rely on manual labor, requiring workers to wipe and scrape off stains section by section. The narrow spaces between the cross diaphragms are particularly difficult to clean, with cleaning a single unit typically taking 4-8 hours, resulting in low efficiency. Furthermore, cleaning requires contact with moving parts, necessitating machine shutdown and causing production interruptions. For companies requiring continuous production, such as food factories, downtime results in significant capacity losses. Moreover, the long-term manual labor investment increases labor costs, and the cleaning effectiveness is dependent on worker experience, easily leading to missed areas, severely impacting production quality and equipment lifespan. Utility Model Content

[0003] In view of the problems mentioned above in the background technology, the purpose of this utility model is to provide a large-angle hook lifting machine that can realize double-sided automatic cleaning.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: A large-angle hook lifting machine capable of double-sided automatic cleaning includes a frame on which a large-angle lifting machine is mounted. A water tank is installed on one side of the frame, and a cleaning mechanism is installed in the water tank. The cleaning mechanism includes a spray assembly, a scraping assembly, and a brush assembly. The spray assembly is located above the scraping assembly, and the brush assembly is located below the scraping assembly. The spray assembly includes a spray frame installed on both the inner and outer sides of the steep-angle elevator. The input end of the spray frame is connected to an external cleaning liquid tank, and the output end of the spray frame is connected to a number of high-pressure nozzles. The output end of the high-pressure nozzles is opposite to the running direction of the steep-angle elevator. The scraping assembly includes a mounting base installed on one side of the pool, on which a first pneumatic push rod is mounted, and an elastic scraper is mounted on the power output end of the first pneumatic push rod. The brush assembly includes a second pneumatic push rod installed on both sides of the pool. The power output end of the second pneumatic push rod is equipped with a waterproof seat, a motor is installed inside the waterproof seat, and a brush is installed at the power output end of the motor.

[0005] Furthermore, the water tank is equipped with an intelligent detection device at the input end of the steep-angle elevator. This structural design allows for real-time monitoring of the contamination level of the elevator conveyor belt.

[0006] Furthermore, the water tank is equipped with an angle fine-tuning device, and the spray frame is mounted on the angle fine-tuning device. This structural design allows for fine-tuning of the spray angle of the high-pressure nozzles, ensuring that the water flow directly reaches deep into the crevices.

[0007] Furthermore, the outer surfaces of both the first and second pneumatic push rods are waterproofed. This structural design ensures stable operation of both the first and second pneumatic push rods.

[0008] Furthermore, the brush is made of ultra-fine nylon bristles with a bristle length of 50-80mm. This structural design improves the cleaning effect.

[0009] The beneficial effects of this utility model are as follows: This utility model adopts an integrated automatic cleaning process of spraying, scraping, and brushing. After the spraying breaks down the adhesion of the stains, the scraping of the elastic scraper and the sweeping of the brush can thoroughly remove the residual stains. Especially for areas such as gaps and corners that are difficult to be completely covered by spraying, compared with a single cleaning method, it can improve the stain removal rate and has a significant effect. It ensures that efficient and thorough cleaning results are achieved without affecting production, changes the inefficient operation mode, does not require additional production time, and realizes the parallel advancement of cleaning and production. It completely solves the core pain points of manual cleaning being time-consuming and inefficient. No manual intervention is required throughout the process, saving manpower. At the same time, the cleaning mechanism is set in the water tank to clean the empty return section of the elevator, and the running section carrying materials is not affected in any way, and no machine stoppage is required throughout the process.

[0011] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] Example 1, as Figure 1 and Figure 2 As shown, a large-angle hook lifting machine that can realize double-sided automatic cleaning is provided. A large-angle lifting machine 2 is installed on the frame 1. A water tank 3 is installed on one side of the frame 1. A cleaning mechanism 4 is installed in the water tank 3. The cleaning mechanism 4 includes a spray assembly, a scraping assembly and a brush assembly. The spray assembly is located on the upper side of the scraping assembly and the brush assembly is located on the lower side of the scraping assembly. The spray assembly includes a spray frame 5 installed on both the inner and outer sides of the steep-angle elevator 2. The input end of the spray frame 5 is connected to the external cleaning liquid tank, and the output end of the spray frame 5 is connected to several high-pressure nozzles 6. The output end of the high-pressure nozzles 6 is opposite to the running direction of the steep-angle elevator 2. The scraping assembly includes a mounting base 7 installed on one side of the pool 3, a first pneumatic push rod 8 mounted on the mounting base 7, and an elastic scraper 9 mounted on the power output end of the first pneumatic push rod 8. The brush assembly includes a second pneumatic push rod installed on both sides of the pool 3. A waterproof seat is installed at the power output end of the second pneumatic push rod, and a motor 10 is installed inside the waterproof seat. A brush 11 is installed at the power output end of the motor 10.

[0013] In this embodiment, during operation, after the inclined elevator 2 transports materials, its empty return section enters the water tank 3, where the cleaning mechanism 4 cleans it. High-pressure nozzles 6 on the spray assembly rinse the bearing and non-bearing surfaces of the inclined elevator 2. The high-pressure nozzles 6 precisely rinse the inner side of the transverse partitions, the hook gaps, and the root of the retaining edge. Since the output end of the high-pressure nozzles 6 is opposite to the running direction of the inclined elevator 2, it forms a reverse rinsing motion in conjunction with the elevator's running direction, enhancing the impact force. After rinsing, the bearing surface enters the scraping assembly. The first pneumatic push rod 8 first pushes the elastic scraper 9 into the inner side of the two side hook partitions. The contact pressure between the elastic scraper 9 and the bearing surface is adjusted by the first pneumatic push rod 8. It can scrape off large areas of residue while avoiding excessive squeezing and damage to the conveyor belt. When the elastic scraper 9 scrapes off the residue, the first pneumatic push rod 8 drives the elastic scraper 9. After the residue is scraped off, the elastic scraper 9 retracts from the hook partition, thus not affecting the normal operation of the large-angle elevator 2. After cleaning by the scraping component, the brush component is activated, and the second pneumatic push rods and motor 10 on both sides are activated. The second pneumatic push rod first pushes the waterproof seat, the waterproof seat drives the motor 10, and the motor 10 drives the brush 11 to enter the inner side of the hook partition on both sides. Then the second pneumatic push rod drives the rotating brush 11 to retreat. While achieving the cleaning effect, it does not affect the operation of the large-angle elevator 2, so that the large-angle elevator 2 can achieve cleaning without stopping.

[0014] In addition, a drying device can be installed on the top of the water tank 3 to quickly dry the surface with low-temperature hot air (≤60℃, to avoid damaging the conveyor belt of the large-angle elevator 2) to prevent residual moisture from causing the material to become damp.

[0015] For large areas of dirt on the conveyor belt bearing surface, the high-pressure nozzle 6 can be a wide-angle fan-shaped nozzle (with a coverage width matching the conveyor belt) to form a uniform water curtain.

[0016] For the inner gaps of the hook-shaped diaphragm and the dead corners at the root of the wavy baffle, the high-pressure nozzle 6 can be a slender columnar nozzle. By finely adjusting the angle, it can ensure that the water flow directly hits the depths of the gaps.

[0017] The spraying device is activated only on the return section of the elevator (empty conveyor belt), and the high-pressure nozzle 6 maintains a safe distance of 50-80mm from the surface of the conveyor belt. This ensures the rinsing force while preventing water from splashing onto the material being conveyed. At the same time, the spraying time is linked to the speed of the conveyor belt (e.g., when the speed is 1.5m / s, the spraying time of a single set of nozzles is set to 3 seconds / segment) to ensure that every stain is fully pre-treated.

[0018] It can also automatically switch the spray medium in the external cleaning fluid tank according to the type of material (such as dust, sticky materials, high-temperature residue). Cleaning dusty materials (such as coal and cement): Use a combination of high-pressure air and a small amount of pure water (air pressure 0.6-0.8MPa). Use airflow to blow floating dust off the surface, and pure water to only wet stubborn dust to prevent dust from clumping when it comes into contact with water. Cleaning highly viscous materials (such as sludge and sugar): Spray hot water at 50-60℃ (the water temperature can be adjusted in real time by the heating device) + 0.5% concentration of neutral surfactant. The heat softens the viscous structure, and the surfactant reduces the adhesion between the material and the conveyor belt. Cleaning high-temperature residues (such as metallurgical slag): Use room temperature water spray (to avoid excessive temperature difference from damaging the conveyor belt), and use high-pressure (1.0-1.2MPa) water flow to impact and break up clumps.

[0019] The process involves spraying to break down the adhesion of stains, followed by scraping with the elastic scraper 9 and cleaning with the brush 11 to thoroughly remove residual stains, especially in areas such as crevices and corners that are difficult to be completely covered by the spray.

[0020] Example 2: Based on Example 1, this example adds the following structure: a smart detection device is installed at the input end of the steep-angle elevator 2 in the water tank 3.

[0021] In this embodiment, the intelligent detection device uses existing high-definition cameras and image recognition to monitor the degree of contamination of the conveyor belt in real time (such as the area and thickness of stains), and automatically triggers cleaning by setting a threshold, thereby achieving energy-saving effects.

[0022] Example 3: Based on Example 1, this example adds the following structure: an angle fine-tuning device is installed in the water tank 3, and the spray frame 5 is installed on the angle fine-tuning device.

[0023] In this embodiment, during use, the angle of the spray frame 5 can be controlled by the angle fine-tuning device so that the water jet from the high-pressure nozzle 6 can directly reach the depths of the crevices, thereby improving the usage effect.

[0024] Example 4: Based on Example 1, this example adds the following structure: the outer surfaces of both the first pneumatic push rod 8 and the second pneumatic push rod are waterproofed.

[0025] In this embodiment, by waterproofing the outer surfaces of the first pneumatic push rod 8 and the second pneumatic push rod, a reliable "protective barrier" is formed on their outer surfaces. This effectively prevents moisture from directly contacting the outer surfaces of the push rods, avoiding corrosion of metal parts, ensuring the cleanliness and smooth flow of the push rod movement gaps, and preventing moisture penetration that could damage the internal sealing structure. This allows the pneumatic push rods to maintain stable operation even in humid and high-moisture environments, significantly reducing the failure rate during equipment operation, extending service life, and lowering replacement costs.

[0026] Example 5: This example adds the following structure to Example 1: the brush 11 is an ultra-fine nylon bristle brush with a bristle length of 50-80mm.

[0027] In this embodiment, by setting the brush 11 as an ultra-fine nylon bristle brush with a bristle length of 50-80mm, it can clean narrow spaces such as the gaps in the partition and the root of the edge. The high-speed rotating brush penetrates deep into the gaps and sweeps out the small residues that have been loosened after spraying.

[0028] When there are residual particles in the fine scratches or textures on the surface of the conveyor belt, a spiral steel wire brush (0.2mm diameter, moderate hardness) can be used in conjunction with a scraper rotating in the opposite direction to remove residual particles embedded in the texture.

[0029] When cleaning oily stains, you can also use a composite brush containing oleophilic fibers to absorb grease while cleaning, reducing secondary staining.

[0030] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
