Description
Technical Field
[0001] The utility model relates to the technical field of belt conveyor cleaning, in particular to a belt conveyor cleaner capable of accurately adjusting torque. Background Art
[0002] Belt conveyor cleaners are mainly used to remove materials transported on the belt surface. Belt conveyor cleaners are suitable for bulk conveyor belt lines at ports, raw material transportation in coal mines and thermal power plants, raw material transportation in steel plants, coal conveyor lines in petrochemical companies, conveyor lines in the sugar industry, chemical conveyor lines, large mixing stations and other bulk material conveying equipment. During the production process of the belt conveyor, due to the influence of material viscosity and electrostatic adsorption, some powdered materials adhere to the belt surface. If they are not cleaned for a long time, the belt conveyor will slip or deviate, resulting in reduced work efficiency. In severe cases, the belt will be damaged or torn, causing major equipment accidents.
[0003] Common belt conveyor cleaners use the cleaner scraper to close to the belt to remove materials from the running belt conveyor. As the cleaner is used, the scraper will be worn, and the contact area and pressing force between the worn scraper and the rubber surface of the belt conveyor will decrease, affecting the cleaning effect or even causing the cleaning effect to fail. Therefore, it is necessary to regularly adjust the degree of pressing between the cleaner scraper and the belt surface. The pressing force between the cleaner scraper and the belt surface is mainly controlled by adjusting the spring compensation mechanism on both sides of the cleaner. Generally, the spring pressing degree is manually adjusted to control the pressing force between the cleaner scraper and the belt. However, this operation mostly relies on experience to adjust the pressure on the spring. Due to the different experience of personnel, the torque adjustment on both sides of the cleaner is often inconsistent or the torque is too large or insufficient, resulting in different degrees of pressing between the two sides of the cleaner scraper and the belt conveyor, and the scraper is unevenly worn, resulting in the situation that the belt conveyor is not cleaned cleanly. Therefore, a cleaner that can accurately adjust and ensure consistent preload on both sides is needed. Utility Model Content

DETAILED DESCRIPTION
[0025] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific implementation methods, but the present invention is not limited thereto.
[0026] like Figures 1 to 6 As shown, a belt conveyor cleaner with precise torque adjustment is composed of a scraper 2 and a scraper frame 3 for mounting the scraper 2. The lower end of the scraper 2 is fixedly connected to the scraper frame 3. The two ends of the scraper frame 3 are respectively circular shafts 31, and the circular shaft 31 is a hollow structure.
[0027] Supporting upright plates 4 are respectively arranged vertically at both ends of the scraper frame 3, and the supporting upright plates 4 are used to support the entire scraper frame 3. A supporting plate 41 is arranged at the bottom of the supporting upright plates 4, and the supporting plate 41 is fixed to the ground; a center hole is respectively opened in the center of each supporting upright plate 4, and the circular shafts 31 at both ends of the scraper frame 3 respectively penetrate the center hole and extend to the outside of the supporting upright plates 4.
[0028] An adjustment disk 5 is provided on the outside of each support vertical plate 4, and a through hole is also provided in the center of the adjustment disk 5. A limited sleeve 51 is fixedly connected to the position of the through hole on the outside of the adjustment disk 5, and the adjustment disk 5 is sleeved on the round shaft 31 at the end of the scraper frame 3 on the side where the adjustment disk 5 is located. A spring 8 is provided between the inner side of each adjustment disk 5 and the outer side of the support vertical plate 4 on the side where the adjustment disk 5 is located. The spring 8 is sleeved on the scraper frame 3, and one end of the spring 8 is fixedly connected to the adjustment disk 5, and the other end is fixedly connected to the support vertical plate 4. The pre-tightening force is applied to the scraper frame 3 by controlling the rotation torque of the spring 8.
[0029] In the present embodiment, a plurality of groups of limiting holes 14 are respectively provided on the circular shaft surfaces at both ends of the scraper frame 3, and the two limiting holes 14 in the same group are symmetrically arranged about the central axis of the scraper frame 3, and the limiting hole 1 in the present embodiment is a long hole provided along the axial direction of the circular shaft; a plurality of groups of limiting holes 15 are also circumferentially provided on the surface of the limiting sleeve 51, and the two limiting holes 15 in the same group are symmetrical about the center of the limiting sleeve 51. When the spring 8 is twisted, the limiting hole 15 is aligned with the corresponding limiting hole 14, and the pin 13 is inserted into the limiting hole 15 and the limiting hole 14 from top to bottom to limit the limiting sleeve 51 so that it does not rotate relative to the circular shaft 31.
[0030] The outer side of each adjusting disk 5 is detachably connected with a fixing disk 6, and a torque wrench 7 is installed in the center of the fixing disk 6. Specifically, a plurality of fixing holes 11 are opened circumferentially on each adjusting disk 5, and three positioning holes 12 are spaced apart on the surface of the fixing disk 6. The fixing disk 11 and the adjusting disk 6 are connected as a whole by a bolt assembly 9 matched with the fixing holes 12 and the positioning holes 13.
[0031] In this embodiment, since the adjustment disk is a finished product purchased from the market, the fixing holes opened on the adjustment disks of different batches may have uneven positions. In order to make the fixed disk adapt to adjustment disks of various specifications, the positioning hole 13 on the fixed disk 6 can be an arc-shaped long hole when the fixed disk is manufactured. When the fixed disk 6 and the adjustment disk 5 are installed, the position of the bolt in the bolt assembly 9 in the arc-shaped long hole is adjustable, which facilitates the installation of the fixed disk 6 and the adjustment disk 5.
[0032] In this embodiment, the torque wrench 7 is a commercially available product. The head of the torque wrench 7 is selected to have a hexagonal hole. A torque nut 10 adapted to the hexagonal hole is fixedly connected to the center position of the outer surface of the fixed disk 6 (the torque nut in this embodiment is a hexagonal nut adapted to the torque wrench). The torque wrench 7 is sleeved on the torque nut 10 through the hexagonal hole. When the torque wrench 7 is pulled, the fixed disk 6 and the adjustment disk 5 rotate as a whole.
[0033] In specific application, the sweeper is first installed as a whole on the outside of the belt 1 in front of the throwing roller of the belt conveyor. The two ends of the scraper 2 are supported by the supporting vertical plates 4. The fixed plates 6 are installed on the adjusting plates 5 on both sides by using the bolt assemblies 9. The set value is input in advance on the torque wrench 7. The torque wrench 7 is sleeved on the torque nut 10. The torque wrenches 7 on both sides of the scraper frame 3 are turned. The torque wrench 7 drives the fixed plate 6 and the adjusting plate 5 to rotate, and then the end of the spring 8 connected to the adjusting plate 5 rotates. The torque wrench 7 drives the adjusting plate 5 to compress the spring 8 through the fixed plate 6; when it rotates to the set torque value, the pin 13 is inserted into the limiting hole 2 15 and the limiting hole 1 14, and the limiting shaft sleeve 51 and the round shaft 31 on the scraper frame 3 are fixed. The spring 8 is rotated and compressed to apply a pre-tightening force, and the pre-tightening force is transmitted to the scraper frame 3. The pressure between the scraper 2 and the belt 1 is adjusted so that the scraper 2 can be close to the belt 1 to ensure effective cleaning.
[0034] This cleaner can realize visual and precise adjustment of the torque at both ends of the scraper frame. Since the setting values of the adjustment torque wrenches on both sides of the scraper are the same, the torque on both sides can also be kept consistent, avoiding eccentric wear of the scraper due to different spring torques on both sides of the scraper, thereby improving the cleaning effect and service life of the scraper.
[0035] Finally, it should be noted that the above-listed examples are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and modifications fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
