Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyors, and particularly relates to a belt limiting structure. Background Technique

[0002] A belt conveyor, that is, a belt conveyor, is a mechanical device widely used in material conveying. It mainly consists of a driving device, a driving roller, a conveyor belt, idlers, a tensioning device, a deflecting roller, and a frame, etc. The belt conveyor drives the driving roller to rotate through the driving device, and then makes the conveyor belt move continuously to achieve the conveying of materials. The working principle of the belt conveyor is based on the continuous rolling of the conveyor belt. Materials are placed on the conveyor belt and are conveyed from one place to another as the conveyor belt moves. In this process, the driving roller drives the belt to roll continuously through the motor to achieve the synchronous rotation of the driven roller, and then drives the materials on the belt for conveying.

[0003] When the existing belt conveyor is performing conveying operations, due to reasons such as uneven conveyor belt tension, roller installation errors, or uneven material distribution, the conveyor belt may deviate during operation. This will not only affect the conveying efficiency but also may cause damage to the equipment. Summary of the Invention

[0004] The purpose of the utility model is to provide a belt limiting structure for the problems existing in the prior art.

[0005] To achieve the above purpose, the utility model is realized by adopting the following technical solutions: A belt limiting structure includes a plurality of pairs of fixed seats arranged on both sides of the belt frame. A wheel shaft is respectively installed on each pair of the fixed seats, and a deviation-preventing wheel is installed at one end of the wheel shaft. The deviation-preventing wheel is used to abut against the side edge of the belt.

[0006] By adopting the above technical solutions, this design can effectively limit the lateral movement of the belt, prevent the belt from deviating during operation, and thus ensure the stable operation of the belt conveyor and the accurate conveying of materials.

[0007] Optionally, a bearing connected to the wheel shaft is installed inside the deviation-preventing wheel.

[0008] By adopting the above technical solutions, installing a bearing inside the deviation-preventing wheel can significantly reduce the friction between the wheel shaft and the deviation-preventing wheel, make the deviation-preventing wheel rotate more smoothly, reduce energy loss and wear. The selection of the bearing should consider the load-bearing capacity, rotational speed, and lubrication conditions in the working environment to ensure its long-term stable operation.

[0009] Optionally, a sealing cover and a snap ring are installed on the deviation-preventing wheel, and a retaining ring is installed on the outer side of the wheel shaft.

[0010] By adopting the above technical solutions, the combination of the sealing cover and the circlip can protect the bearing from the intrusion of impurities such as dust and moisture, thereby extending the service life of the bearing. At the same time, the setting of the retaining ring can prevent the axial movement of the wheel axle during operation, ensuring the stable position of the anti-deviation wheel. These designs together improve the reliability and durability of the entire limiting structure.

[0011] Optionally, a connecting groove is provided at one end of the wheel axle away from the anti-deviation wheel, and the connecting groove is connected to the fixed seat by a fixing bolt.

[0012] By adopting the above technical solutions, by providing a connecting groove and using a fixing bolt to connect the wheel axle to the fixed seat, the installation and disassembly of the wheel axle can be conveniently achieved, facilitating maintenance and replacement. At the same time, tightening the fixing bolt and matching it with a gasket can ensure the tightness and stability of the connection, preventing loosening or vibration during operation.

[0013] Optionally, the anti-deviation wheel includes a cylindrical side wall and a circular top cover, and a plurality of limiting grooves are provided on the inner side of the cylindrical side wall.

[0014] By adopting the above technical solutions, the setting of the limiting grooves can be used to limit the bearings, sealing covers and circlips inside the anti-deviation wheel.

[0015] Optionally, at least one pair of anti-deviation wheels facing opposite directions are provided on each side of the belt frame, and the distance between each pair of anti-deviation wheels is the same.

[0016] By adopting the above technical solutions, providing at least one pair of anti-deviation wheels facing opposite directions on each side can form a two-way limit on the belt, further improving the effect of preventing deviation. At the same time, keeping the distance between each pair of anti-deviation wheels the same can ensure that the belt is uniformly constrained throughout the operation, avoiding problems caused by local stress concentration.

[0017] Optionally, the anti-deviation wheels on both sides of the belt frame are symmetrically distributed.

[0018] By adopting the above technical solutions, the symmetrical distribution of the anti-deviation wheels on both sides of the belt frame can ensure that the limiting forces on both sides of the belt are balanced, helping to maintain the stable operation of the belt. This symmetrical design also helps to improve the aesthetics and structural compactness of the entire belt conveyor system.

[0019] Optionally, a limiting groove is provided on the surface of the anti-deviation wheel, and the limiting groove is provided along the outer circumferential direction of the anti-deviation wheel.

[0020] By adopting the above technical solutions, the effect of preventing the belt from deviating is further enhanced.

[0021] Optionally, a wear-resistant pad is bonded to the surface of the anti-deviation wheel, and the wear-resistant pad is in contact with the side edge of the belt.

[0022] By adopting the above technical solution, the direct contact and friction between the belt and the anti-deviation wheel can be reduced, thereby reducing the wear rate of the belt and extending its service life. At the same time, the wear-resistant pad can also protect the anti-deviation wheel from the direct impact and wear of the belt.

[0023] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0024] 1. By installing the anti-deviation wheel and setting appropriate perforations and spacings on the fixed seat, it is ensured that the anti-deviation wheel can be accurately and stably installed on both sides of the belt frame. This design can effectively limit the lateral movement of the belt and prevent the belt from running off during operation, thus ensuring the stable operation of the belt conveyor and the accurate conveying of materials; 2. The design of the belt limiting structure is compact and reasonable, and the connection between each component is tight and reliable. The installation and disassembly of components such as the fixed seat, wheel shaft, and anti-deviation wheel are relatively simple, facilitating the maintenance and repair of the equipment; 3. The sealing cover and snap ring installed on the anti-deviation wheel can effectively prevent impurities such as dust and moisture from entering the bearing, thus ensuring the lubrication performance and service life of the bearing; 4. The design of the belt limiting structure has strong adaptability and can be applied to belt frames of different specifications and models. At the same time, its simple and reliable structure makes it easy to promote and popularize. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0033] As Figure 1 shown in -3, the specific solution of the embodiment is as follows: A belt limiting structure includes a plurality of pairs of fixed seats 2 arranged on both sides of the belt frame 1. The belt is installed on the belt frame 1. A driving device and a rotating device for driving the belt to operate are provided on the belt frame 1. A wheel shaft 3 is respectively installed on each pair of the fixed seats 2. One end of the wheel shaft 3 is installed with an anti-deviation wheel 4. The main function of the anti-deviation wheel 4 is to prevent the belt from deviating during operation. The anti-deviation wheel 4 includes a cylindrical side wall and a circular top cover. A plurality of limiting grooves are formed on the inner side of the cylindrical side wall. The anti-deviation wheel 4 is used to abut against the side edge of the belt;

[0034] A bearing 5 connected to the wheel shaft 3 is installed in the anti-deviation wheel 4. The number of the bearings 5 is two, and a spacer 501 is provided between the two bearings 5. A through hole for the wheel shaft 3 to pass through is formed on the surface of the spacer 501. The anti-deviation wheel 4 is flexibly rotationally connected to the wheel shaft 3 through the bearing 5, and the spacer 501 between the bearings 5 plays a role of separating and supporting to ensure the normal operation of the bearing 5. At the same time, the bearing 5 enables the anti-deviation wheel 4 to freely rotate around the wheel shaft 3, reducing friction and wear. The spacer 501 is made of high-strength engineering plastic or wear-resistant alloy. The engineering plastic spacer can reduce the overall weight and has good wear resistance; the wear-resistant alloy spacer can provide higher strength and corrosion resistance and is suitable for harsh working environments.

[0035] A sealing cover 6 and a circlip 7 are installed on the anti-deviation wheel 4. The sealing cover 6 is frustum-shaped and is used to close the installation groove to prevent dust and impurities from entering. A retaining ring 8 is installed on the outer side of the wheel shaft 3. The circlip 7 can prevent the bearing 5 at the lower end from loosening or falling off. The retaining ring 8 plays a role in further fixing and limiting, ensuring the stable and reliable installation of the wheel shaft 3 and the anti-deviation wheel 4 on the belt frame 1. The retaining ring 8 is a spring retaining ring or a quick-release retaining ring. The spring retaining ring can provide more uniform radial pressure to ensure the stable installation of the wheel shaft 3; the quick-release retaining ring is convenient for quick disassembly and installation, improving the maintenance efficiency.

[0036] A connection groove 301 is provided at one end of the wheel shaft 3 away from the anti-deviation wheel 4. The connection groove 301 is connected to the fixed seat 2 through a fixing bolt 302. A gasket 303 is installed between the fixing bolt 302 and the fixed seat 2. One end of the wheel shaft 3 is used to install the anti-deviation wheel 4, and the other end is tightly connected to the fixed seat 2 through the connection groove 301 and the fixing bolt 302. The gasket 303 is used to increase the stability and sealing performance of the connection. The design of the fixing bolt 302 and the connection groove 301 enables the wheel shaft 3 to be conveniently disassembled and installed, facilitating the maintenance and repair of the equipment. At least one pair of anti-deviation wheels 4 facing in opposite directions are provided on each side of the belt frame 1, and the distance between each pair of anti-deviation wheels 4 is the same. The anti-deviation wheels 4 on both sides of the belt frame 1 are symmetrically distributed.

[0037] Embodiment 2, as Figure 4 shown. The difference between the belt limiting structure provided in this embodiment and the belt limiting structure in Embodiment 1 is that: the anti-deviation wheel 4 in Embodiment 2 is changed. A limiting groove 9 is provided on the surface of the anti-deviation wheel 4. The limiting groove 9 is circumferentially provided along the outer side of the anti-deviation wheel 4. After installation, the belt is located inside the limiting groove 9. The setting of the limiting groove 9 further enhances the effect of preventing the belt from running off. At the same time, the limiting groove 9 provides an accurate guiding path for the belt, ensuring that the belt can also be closely attached to the limiting groove 9 during high-speed operation, thereby greatly limiting the lateral movement space of the belt. This design enables the belt to quickly return to the correct running track even when subjected to certain external forces or vibrations.

[0038] Embodiment 3, as Figure 5As shown in the figure, the difference between the belt limiting structure provided in this embodiment and the belt limiting structure in Embodiment 1 is that: the anti-deviation wheel 4 in Embodiment 2 has been changed. A wear-resistant pad 10 is bonded to the surface of the anti-deviation wheel 4. The wear-resistant pad 10 contacts the side edge of the belt. The wear-resistant pad 10 is made of rubber material, which has good wear resistance, elasticity and tear resistance. The wear-resistant pad 10 serves as a buffer layer between the belt and the anti-deviation wheel 4, which can reduce the direct contact and friction between the belt and the anti-deviation wheel 4, thereby reducing the wear speed of the belt and extending its service life. At the same time, the wear-resistant pad 10 can also protect the anti-deviation wheel 4 from the direct impact and wear of the belt.

[0039] The installation steps of the above embodiment are as follows:

[0040] Weld a pair of fixed seats 2 to the belt frame of the belt frame 1 at a predetermined position, ensuring that the distance between them is adapted to the length of the axle 3;

[0041] Install a pair of bearings 5 on the axle 3, and install a spacer sleeve 501 between the two bearings 5, ensuring that the through hole of the spacer sleeve 501 is aligned with the axle 3 so that the axle 3 can pass through smoothly, ensuring that the anti-deviation wheel 4 is correctly connected to the bearing 5 and can rotate freely around the axle 3;

[0042] Align the installation groove of the anti-deviation wheel 4 with one end of the axle 3, and insert the axle 3 into the installation groove;

[0043] Use a circlip 7 to fix the sealing cover 6 on the installation groove to prevent it from loosening or falling off;

[0044] Install a retaining ring 8 on the outside of the axle 3, ensuring that the retaining ring 8 can closely fit the axle 3 and play a role of fixing and limiting;

[0045] Pass the axle 3 through the perforation on the fixed seat 2, ensuring that the axle 3 can be stably installed between the two fixed seats 2;

[0046] At the end of the axle 3 away from the anti-deviation wheel 4, insert the fixing bolt 302 into the connecting groove 301 and tighten it, while ensuring that the gasket 303 is located between the fixing bolt 302 and the fixed seat 2 to increase the stability and sealing of the connection;

[0047] After completing all the installation steps, carefully check whether all the connection parts are firmly fastened and reliable, without looseness or misalignment;

[0048] Start the belt conveyor for a trial run, observe whether the working state of the anti-deviation wheel 4 is normal, and ensure that the belt has no deviation during operation.
