Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment structure for conveyor belt transportation, and in particular relates to a conveyor belt cleaning device. Background Technology

[0002] In crushing systems, ore transportation is mainly done via conveyor belts. During ore transport, cleaning equipment needs to be installed at the lower part of the lower conveyor belt to remove residual slag and mud from the working surface of the belt. This allows the slag and mud to fall into a fixed position for easy disposal, preventing them from falling into other parts of the conveyor belt corridor and increasing the workload of cleaning and maintenance. Existing belt cleaners are in the form of a rotating shaft. The rotation of the shaft keeps the scraper blades in close contact with the working surface of the belt. The distance between the scraper blades and the working surface of the belt is adjusted by bolts on the reaction springs on both sides of the shaft. As the scraper blades wear down, the pressure between the scraper blades and the working surface of the belt gradually decreases. Maintenance personnel need to adjust the pressure in a timely manner to ensure that the pressure between the scraper blades and the working surface of the belt remains at an ideal value. In severe cases, this can affect the smooth operation of production. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies and provide a tape cleaning device. This device ensures that the pressure between the scraper and the working surface of the tape remains constant without manual adjustment, and that the adjustment method is convenient and quick.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tape cleaning device, characterized in that it includes a scraping mechanism 1, two sets of support mechanisms located at both ends of the scraping mechanism, and a lifting mechanism.

[0006] The scraping mechanism includes a crossbeam, a scraper, a connecting plate, and a bolt assembly. The crossbeam is a channel steel crossbeam. The lower part of the scraper is fixed to the centerline of the web of the channel steel crossbeam by the connecting plate and the bolt assembly, so that the scraper is placed inside the conveyor belt frame and comes into contact with the downward conveyor belt.

[0007] The aforementioned support mechanisms consist of two parts, symmetrically arranged on both sides of the conveyor belt frame. Each support mechanism includes an upper crossbeam, two uprights, and a lower crossbeam. The upper crossbeam is fixedly connected at both ends to the upper ends of the two uprights, and the lower crossbeam is located at the lower ends of the two uprights. Two steel bars are spaced apart on the upper part of the lower crossbeam, forming a crossbeam groove. The upper ends of the two uprights are fixed to the conveyor belt frame via the upper crossbeam, and the lower ends of the two uprights are fixed to the ground foundation. The two ends of the channel steel crossbeam flanges pass through the crossbeam grooves of the two support mechanisms and are positioned outside the device, sliding up and down within the crossbeam grooves. Limiting angle irons are symmetrically installed on the web plates at both ends of the channel steel crossbeam via bolts. Sealing plates are installed at the positions corresponding to the limiting angle irons on the flanges at both ends of the channel steel crossbeam. Steel wire rope lifting rings are installed at the top of the flanges at both ends of the channel steel crossbeam. The upper crossbeam, two uprights, and lower crossbeam of the support mechanism are all assembled from angle steel. Using angle steel not only provides good stability but also facilitates the fixing and connection of various components.

[0008] The lifting mechanism includes a first guide pulley, a second guide pulley, a wire rope, and a counterweight device. The first guide pulley is mounted on the upper crossbeam, and the second guide pulley is mounted parallel to the first guide pulley on the conveyor belt frame. One end of the wire rope is connected to a wire rope shackle, and the other end of the wire rope passes around the first and second guide pulleys and is fixedly connected to the counterweight device. The distance between the scraper and the downward conveyor belt is adjusted by adjusting the counterweight device to drive the channel steel crossbeam to rise and fall within the crossbeam groove.

[0009] As a further description of the above technical solution: the counterweight device consists of a chassis and a counterweight.

[0010] As a further description of the above technical solution: The upper crossbeam, two columns and the lower crossbeam of the support mechanism are all assembled from angle steel.

[0011] This utility model has the following beneficial effects:

[0012] 1. When the scraper of the cleaning device wears out, the tension of the scraping mechanism can be adjusted by increasing the number of counterweights, so that the scraper slides upward along the crossbeam groove and automatically compensates. This facilitates the adjustment of the distance between the scraper of the cleaning device and the working surface of the conveyor belt, ensuring that the cleaning device and the downward conveyor belt maintain the best contact surface when they come into contact, reducing labor costs, reducing on-site environmental pollution, and eliminating safety hazards.

[0013] 2. This utility model has the characteristics of simple structure, convenient and quick installation and maintenance, and good cleaning effect, which reduces the downtime for installation, dismantling and operation of the cleaning device. Attached Figure Description

However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0020] Please refer to Figures 1-5 As shown, this utility model discloses a tape cleaning device, characterized in that it includes a scraping mechanism 1, two sets of support mechanisms 2 located at both ends of the scraping mechanism 1, and a lifting mechanism 3.

[0021] The scraping mechanism 1 includes a crossbeam, a scraper 12, a connecting plate 13, and a bolt assembly. The crossbeam is a channel steel crossbeam, and the lower part of the scraper 12 is fixed to the centerline of the web plate 111 of the channel steel crossbeam through the connecting plate 13 and the bolt assembly.

[0022] The support mechanism consists of two parts, symmetrically arranged on both sides of the tape frame 4. Each support mechanism includes an upper crossbeam 21, two uprights 22, and a lower crossbeam 23. The two ends of the upper crossbeam 21 are fixedly connected to the upper ends of the two uprights 22, respectively. The lower crossbeam 23 is located at the lower ends of the two uprights 22. Two steel bars 24 are spaced apart on the upper part of the lower crossbeam 23, forming a crossbeam groove 25. The upper ends of the two uprights 22 are fixed to the tape frame 4 via the upper crossbeam 21. The lower end of 22 is fixed on the ground foundation. The two ends of the channel steel crossarm wing plate 112 pass through the crossarm slide groove 25 of the two support mechanisms and are placed outside the device, and slide up and down in the crossarm slide groove 25. The web plates 111 at both ends of the channel steel crossarm are symmetrically provided with limiting angle irons 14 by bolts. The ends of the wing plates 112 of the channel steel crossarm are provided with sealing plates 15 at the positions corresponding to the limiting angle irons 114. The top of the wing plates 112 at both ends of the channel steel crossarm is provided with wire rope lifting rings 16.

[0023] The lifting mechanism includes a first guide pulley 31, a second guide pulley 33, a wire rope 32, and a counterweight device. The first guide pulley 31 is mounted on the upper crossbeam 21, and the second guide pulley 33 is mounted parallel to the first guide pulley 31 on the conveyor belt frame 4. The first end of the wire rope 32 is connected to the wire rope shackle 16, and the other end of the wire rope passes around the first guide pulley 31 and the second guide pulley 33 and is fixedly connected to the counterweight device.

[0024] As a further description of the above technical solution: the counterweight device consists of a chassis 34 and a counterweight 35.

[0025] The operation of this tape cleaning device is as follows: After installing the support mechanisms at both ends of the scraping mechanism 1, the upper end of the scraper 12 is pressed tightly against the lower surface of the descending tape 5. After installing the counterweight 35, gravity causes the channel steel crossbeam to move upward, ensuring optimal contact between the scraper 12 and the tape 5. When the tape roller rotates, the scraper scrapes away foreign objects on the surface of the tape 5, achieving the effect of removing surface foreign objects without the need for manual disassembly and adjustment.
