Description

Technical Field

[0001] This utility model relates to the field of sprocket support technology, specifically a pairing and positioning device for sprocket supports on a chain conveyor. Background Technology

[0002] A sprocket is a wheel with interlocking chain teeth, used to mesh with precisely pitched blocks on a link chain or cable. Sprockets are widely used in mechanical transmissions in industries such as chemical, textile machinery, escalators, wood processing, automated parking garages, agricultural machinery, food processing, instrumentation, and petroleum.

[0003] For example, patent document CN 222932092 U discloses an assembly and positioning device for a sprocket bracket on a chain conveyor. The device includes a base frame, a first threaded rod rotatably connected within the base frame, two slide blocks fitted onto the first threaded rod, and brackets fixedly installed at the top of each slide block. A second threaded rod rotatably connects to each of the two brackets, and a slider is fitted onto each of the two second threaded rods. A first positioning frame is fixedly installed on one side of each slider that is close to the other. This assembly and positioning device for the sprocket bracket on the chain conveyor allows for adjustment and alignment of the height of multiple positioning holes, thus avoiding the problem of pre-drilled hole position deviations that are common with traditional positioning frames welded using resist welding, which can prevent the proper installation and use of subsequent parts. Furthermore, it allows for adjustment of the distance between the two uprights according to usage needs, facilitating the installation of conveying parts such as slats, metal mesh belts, and roller conveyors of different lengths, thereby further improving the applicability of the equipment.

[0004] However, in practice, due to its own structural limitations, this structure can only perform simple sprocket bracket adjustment operations on chain conveyors. It cannot meet the needs of some chain conveyors that require quick disassembly, assembly, and movement. At the same time, the equipment cannot guarantee that the chain conveyor can transport large loads more stably, and cannot meet daily usage needs. Therefore, it is urgent to design a pairing and positioning device for sprocket brackets on chain conveyors to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a pairing and positioning device for the sprocket bracket on a chain conveyor, so as to solve the problem mentioned in the background art that, in actual operation, the existing structure is limited by its own structure and can only perform simple distance adjustment operation on the sprocket bracket on the chain conveyor. It cannot meet the needs of some chain conveyors that require quick disassembly, assembly and movement. At the same time, the equipment cannot guarantee that the chain conveyor can carry out the transport of large loads more stably and cannot meet the daily use needs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pairing and positioning device for a sprocket bracket on a chain conveyor, comprising a first mounting frame and a second mounting frame, wherein the first mounting frame and the second mounting frame have the same structure but opposite directions, and both the inner walls of the first mounting frame and the second mounting frame are provided with sprocket assemblies, and the bottom ends of the first mounting frame and the second mounting frame are provided with pressing components. The sprocket assembly includes a first sprocket and a second sprocket. The first sprocket is disposed at the center of the inner wall of the first mounting frame, and the second sprocket is disposed at the center of the inner wall of the second mounting frame. The pressing assembly includes a ventilated base, and the bottom ends of the first mounting frame and the second mounting frame are provided with the ventilated base.

[0007] Preferably, the ventilation base is provided with a telescopic airbag inside, one end of the telescopic airbag is provided with a limiting top plate, and one end of the ventilation base is provided with a control air pump.

[0008] Preferably, a mating pad is provided between the first mounting frame and the second mounting frame.

[0009] Preferably, the top of the first mounting frame is provided with a first adjusting seat, and the top of the second mounting frame is provided with a second adjusting seat.

[0010] Preferably, both the first and second adjusting seats are provided with adjusting push rods inside.

[0011] Preferably, a sprocket tooth seat is provided on the side of the first sprocket, and a universal joint is provided at one end of the first sprocket.

[0012] Preferably, the inner walls of the first and second mounting frames are provided with limiting ring seats, and the limiting ring seats are provided with buffer sleeves inside.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The assembly and positioning device for the sprocket bracket on this chain conveyor, through the inclusion of a first mounting frame, a second mounting frame, a first sprocket, a second sprocket, a first adjusting seat, a second adjusting seat, an adjusting push rod, a sprocket tooth seat, a universal joint, a limiting ring seat, and a buffer sleeve, enables more efficient assembly and positioning of the sprocket bracket on the chain conveyor. In actual use, the operator first fully unfolds the first and second mounting frames using the adjusting push rods inside the first and second adjusting seats at the top. Then, the chain conveyor is placed between the first and second mounting frames and installed with the first and second sprockets between them. At this point, the sprocket tooth seats on the sides of the first and second sprockets align with the chain conveyor. Simultaneously, the first and second sprockets can be mounted together via the universal joint at one end, and the limiting ring seat's inner wall buffer sleeve allows for appropriate universal buffering adjustments of the chain conveyor, ensuring stability during transport and facilitating the assembly and positioning of the chain conveyor, demonstrating the practicality of the equipment design.

[0014] The assembly and positioning device for the sprocket bracket of this chain conveyor, through the inclusion of a first mounting frame, a second mounting frame, a ventilation base, a telescopic airbag, a limiting top plate, a control air pump, and docking rubber pads, further enhances the overall performance of the equipment. During daily use, operators can activate the control air pump at one end of the ventilation base to inflate or deflate the telescopic airbag inside. This allows the limiting top plate at one end of the telescopic airbag to engage with both sides of the bottom of the chain conveyor, providing support and limiting at the bottom of the conveyor and ensuring stability during heavy load transport. Furthermore, when the first and second mounting frames are adjusted using the adjusting push rods inside the first and second adjusting seats, they can be positioned and stored using the docking rubber pads between the first and second mounting frames, facilitating quick relocation and disassembly. This demonstrates the comprehensive design of the equipment. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 One embodiment provided by this utility model: A pairing and positioning device for a sprocket bracket on a chain conveyor includes a first mounting frame 1 and a second mounting frame 2. The first mounting frame 1 and the second mounting frame 2 have the same structure but are oriented in opposite directions. Both the inner walls of the first mounting frame 1 and the second mounting frame 2 are provided with sprocket assemblies. The bottom ends of the first mounting frame 1 and the second mounting frame 2 are provided with pressing assemblies. The side of the first sprocket 3 is provided with a sprocket tooth seat 13. One end of the first sprocket 3 is provided with a universal joint 14. The inner walls of the first mounting frame 1 and the second mounting frame 2 are provided with limit ring seats 15. The inside of the limit ring seats 15 is provided with a buffer rubber sleeve 16. When the first mounting frame 1 and the second mounting frame 2 are adjusted by the adjusting push rod 12 inside the first adjusting seat 10 and the second adjusting seat 11, they can also be positioned and stored by the mating rubber pad 9 between the first mounting frame 1 and the second mounting frame 2, allowing for quick movement, disassembly, and use.

[0019] The sprocket assembly includes a first sprocket 3 and a second sprocket 4. The first sprocket 3 is located at the center of the inner wall of the first mounting frame 1, and the second sprocket 4 is located at the center of the inner wall of the second mounting frame 2. The pressing assembly includes a ventilated base 5. The ventilated base 5 is located at the bottom of the first mounting frame 1 and the second mounting frame 2. The ventilated base 5 has a telescopic airbag 6 inside. One end of the telescopic airbag 6 has a limiting top plate 7. One end of the ventilated base 5 has a control air pump 8. A mating pad 9 is provided between the first mounting frame 1 and the second mounting frame 2. The top of the first mounting frame 1 has a first adjusting seat 10, and the top of the second mounting frame 2 has a second adjusting seat 11. Both the first adjusting seat 10 and the second adjusting seat 11 have adjusting push rods 12 inside. The chain conveyor is placed between the first mounting frame 1 and the second mounting frame 2 and installed at the first sprocket 3 and the second sprocket 4 between the first mounting frame 1 and the second mounting frame 2. At this time, the sprocket tooth seats 13 on the sides of the first sprocket 3 and the second sprocket 4 are mated with the chain conveyor.

[0020] Working Principle: During use, the operator first fully unfolds the first mounting frame 1 and the second mounting frame 2 using the adjusting push rods 12 inside the first adjusting seat 10 and the second adjusting seat 11 at the top. Then, the chain conveyor is placed between the first mounting frame 1 and the second mounting frame 2, and installed at the first sprocket 3 and the second sprocket 4 between the first mounting frame 1 and the second mounting frame 2. At this time, the sprocket tooth seats 13 on the sides of the first sprocket 3 and the second sprocket 4 are connected to the chain conveyor. Simultaneously, the first sprocket 3 and the second sprocket 4 can be installed together through the universal joint 14 at one end, and the chain conveyor can be appropriately adjusted for universal buffering by the buffer sleeve 16 on the inner wall of the limiting ring seat 15, ensuring the stability of the chain conveyor during transport and making it more convenient. The assembly and positioning of the chain conveyor can be completed quickly. During daily use, the operator can start the air pump 8 at one end of the ventilation base 5 to inflate and deflate the telescopic airbag 6 inside the ventilation base 5. This causes the limiting top plate 7 at one end of the telescopic airbag 6 to abut against the bottom sides of the chain conveyor, providing support and limiting at the bottom of the chain conveyor and ensuring the stability of the chain conveyor when transporting large loads. At the same time, when the first mounting frame 1 and the second mounting frame 2 are adjusted by the adjusting push rod 12 inside the first adjusting seat 10 and the second adjusting seat 11, they can also be positioned and stored by the mating rubber pad 9 between the first mounting frame 1 and the second mounting frame 2, allowing for quick movement, assembly, and disassembly. The above is the complete working principle of this utility model.
