Description

Technical Field

[0001] This invention relates to the field of elevator chain technology, and more specifically, to a double-sided roller elevator chain. Background Technology

[0002] Elevator chains are commonly used in conveying equipment in chemical and food production industries. They are primarily used to lift materials, with two chains on the left and right sides simultaneously driving the buckets to lift the goods. Chain transmission typically occurs in enclosed spaces under harsh working conditions, making them highly susceptible to dust, moisture, and corrosion. The chains are prone to fatigue and wear, leading to failure. Therefore, elevator chains are required to have high strength, high wear resistance, and impact resistance. The chain lengths of the two chains must be uniform, with the absolute error of the chain length controlled within 0.05% to ensure the stability and safety of the conveying process on both sides.

[0003] Chinese Patent Publication No. CN219525165U discloses a hoist chain, including a base chain for transmission, on which a plurality of side plate mechanisms for fixing hoppers are installed; the side plate mechanism includes two fixed shafts respectively fixed to two adjacent pins of the base chain, and a side plate body for installing hoppers is fixed on the two fixed shafts. Each of the two fixed shafts is fitted with a support sleeve disposed between the side plate body and the base chain, and a roller is rotatably installed at the end of the side plate body away from the fixed shaft.

[0004] The above solution addresses the issue of frequent chain replacements required to ensure bucket stability and safety during use of the hoist chain in harsh conditions. However, during operation, uneven track surfaces or dirt buildup can cause the rollers to bounce, leading to chain slippage or tooth skipping. Furthermore, the chain gradually elongates over time, and failure to adjust its tension can also cause slippage or tooth skipping, potentially resulting in chain breakage or tooth breakage and generating significant noise. This not only reduces the chain's lifespan but also lowers transmission efficiency. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, the present invention provides a double-sided roller elevator chain, which enhances the support strength of the fixed plate, improves the fixed plate's support capacity for the hopper, prevents the fixed plate from deforming when the hopper is too heavy, avoids the basic chain from skipping grooves or teeth, and improves the service life of the basic chain. At the same time, it ensures the stability and safety of the hopper, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a double-sided roller elevator chain, comprising a base chain, wherein multiple support components are fixedly connected to the sides of the base chain; each support component includes a mounting plate, wherein a fixing plate is integrally formed on the side of the mounting plate, the mounting plate and the fixing plate forming a Z-shape, both ends of the fixing plate are fixedly connected to limit blocks, the middle of the fixing plate has an installation hole for installing a hopper, and both sides of the mounting plate have sleeve holes; the limit block has a movable groove inside, a lifting block is slidably installed inside the movable groove, a fixed shaft is fixedly connected to the side of the lifting block near the base chain, a support roller is rotatably installed on the outer surface of the fixed shaft, a telescopic rod is fixedly connected between the top of the movable groove and the lifting block, a buffer spring is movably sleeved on the outer surface of the telescopic rod, and the upper and lower ends of the lifting block are fixedly connected to one side of the movable groove and the top of the lifting block, respectively.

[0007] In a preferred embodiment, the base chain includes two inner chain plates, with sleeves fitted inside the two inner chain plates and pins fitted inside the sleeves. Outer chain plates are rotatably mounted on the outer surfaces of both sides of the inner chain plates, and the outer chain plates are movably sleeved on the outer surfaces of the sleeves. Rollers are movably sleeved on the outer surface of the sleeve located between the two inner chain plates. A support sleeve is movably sleeved on one side of the pin. The mounting plate is fixedly sleeved on the outer surface of the pin located on the side of the support sleeve through a sleeve hole.

[0008] In a preferred embodiment, a limiting component is further included, the limiting component comprising a support frame and support plates at both ends of the top of the support frame. The support frame is triangular, and a first bolt is detachably installed inside the bottom end of the support frame via a nut. A first support rod is fixedly connected to one side of the first bolt, and an auxiliary roller is rotatably installed on the side of the first support rod away from the first bolt.

[0009] In a preferred embodiment, a second support rod is fixedly connected to the end of the lifting block away from the support roller, and a second bolt is fixedly connected to one side of the second support rod. The upper end of the support plate is detachably mounted on the outer surface of the second bolt by a nut, and the length of the second support rod is the same as the length of the first support rod.

[0010] In a preferred embodiment, the support sleeve includes a limiting plate, on one side of which two support rings are fixedly installed. The two support rings are respectively sleeved on the outer surface of one end of two connected pins. The limiting plate is located on the side away from the base chain. An arc-shaped limiting groove is formed at the top of one end of the limiting plate. The arc-shaped limiting groove is movably sleeved on the outer surface of the fixed shaft. The width of the arc-shaped limiting groove is greater than the diameter of the fixed shaft, and a gap is left between the arc-shaped limiting groove and the fixed shaft.

[0011] The technical effects and advantages of this invention are as follows:

[0012] 1. This invention provides support rollers on both sides of the fixed plate, allowing the weight of the hopper to be transferred to the track used for installing the base chain. This makes the fixed plate more evenly stressed, thereby increasing its support strength and ability to support the hopper, and preventing deformation of the fixed plate when the hopper is too heavy.

[0013] 2. This invention utilizes a lifting block to drive a support roller to move along the side of a fixed plate. When the surface of the track used to install the base chain is not flat enough or is covered with dirt, the support roller, as it rolls on the track surface, will be subjected to force, causing the support roller to drive the lifting block to rise. The reaction force of the buffer spring reduces the jumping of the support roller, thereby maintaining the stability of the base chain during transmission, preventing the base chain from jumping out of the groove or teeth, improving the service life of the base chain, and ensuring the stability and safety of the hopper.

[0014] 3. This invention controls the distance between the support roller and the base chain by selecting the length of the support sleeve during production, thereby enabling the support roller to run on tracks at different distances from the base chain. By selecting the height of the support plate during production, the distance between the auxiliary roller and the support roller is controlled, allowing the auxiliary roller and support roller to adapt to support tracks of different thicknesses. By controlling the production length of the second support rod and the first support rod, tracks of different widths can be accommodated, thereby improving the adaptability of the device.

[0015] 4. The present invention uses a limiting component to make the auxiliary roller roll at the bottom of the track on which the basic chain is installed. By supporting the roller, the hopper is supported. At the same time, the auxiliary roller at the bottom of the track and the supporting roller at the top of the track limit the movement of the basic chain, thus preventing the basic chain from swinging left and right or moving up and down during operation. This ensures the smooth operation of the basic chain and can adapt to more complex transmissions.

[0016] 5. This invention utilizes a support sleeve. When the base chain has been in operation for a long time, it will elongate, and the distance between the two support components will gradually increase. When the fixed shaft inside one support component comes into contact with the inner wall of the arc-shaped limiting groove, friction will occur, and a sound will be emitted to remind maintenance personnel to replace the base chain in time, or adjust the tension of the base chain, thereby improving the smoothness of the base chain operation, avoiding the phenomenon of the base chain jumping out of the groove or skipping teeth, and improving the transmission efficiency.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] First Embodiment

[0028] Appendix Figure 1-4 In one embodiment of the present invention, the stability and safety of the bucket operation are further improved by further improving the existing elevator chain.

[0029] A double-sided roller elevator chain includes a base chain 1, with multiple support components 2 fixedly connected to the sides of the base chain 1. Each support component 2 includes a mounting plate 21, with a fixed plate 22 integrally formed on the side of the mounting plate 21. The mounting plate 21 and the fixed plate 22 form a Z-shape. Limiting blocks 24 are fixedly connected to both ends inside the fixed plate 22. A mounting hole 23 for mounting a hopper is opened in the middle of the fixed plate 22. Support rollers 26 roll on a track for mounting the base chain 1. Through the mounting hole 23, the hopper is bolted to the inside of the fixed plate 22. The weight of the hopper is transmitted to the track for mounting the base chain 1 through the support rollers 26 on both sides of the fixed plate 22, making the fixed plate 22 more evenly stressed, thereby improving the support strength of the fixed plate 22, increasing the support capacity of the fixed plate 22 for the hopper, and preventing the fixed plate 22 from deforming when the weight of the hopper is too large.

[0030] The mounting plate 21 has socket holes 27 on both sides inside; the limiting block 24 has a movable groove 241 inside, and a lifting block 242 is slidably installed inside the movable groove 241. A fixed shaft 25 is fixedly connected to the side of the lifting block 242 near the base chain 1. A support roller 26 is rotatably installed on the outer surface of the fixed shaft 25. A telescopic rod 243 is fixedly connected between the top of the movable groove 241 and the lifting block 242. A buffer spring 244 is movably sleeved on the outer surface of the telescopic rod 243. The upper and lower ends of the lifting block 242 are fixedly connected to one side of the movable groove 241 and the top of the lifting block 242, respectively. The lifting block 242 drives the support roller 26 to move on the side of the fixed plate 22. When the surface of the track used to install the base chain 1 is not flat enough or is covered with dirt, the support roller 26 will be subjected to force as it rolls on the track surface, causing the support roller 26 to drive the lifting block 242 to rise. The reaction force of the buffer spring 244 reduces the jumping of the support roller 26, thereby maintaining the stability of the base chain 1 during transmission, avoiding the base chain 1 from jumping out of the groove or teeth, improving the service life of the base chain 1, and ensuring the stability and safety of the hopper.

[0031] As attached Figure 3 As shown, the basic chain 1 includes two inner chain plates 11, with sleeves 16 fitted inside the two inner chain plates 11. Pins 12 are fitted inside the sleeves 16. Outer chain plates 14 are rotatably mounted on the outer surfaces of both sides of the inner chain plates 11. The outer chain plates 14 are movably fitted onto the outer surfaces of the sleeves 16. Rollers 13 are movably fitted onto the outer surfaces of the sleeves 16 located between the two inner chain plates 11. A support sleeve 15 is movably fitted onto one side of the pin 12. A mounting plate 21 is fixedly fitted onto the outer surface of the pin 12 located on the side of the support sleeve 15 through a sleeve hole 27. The distance between the support roller 26 and the basic chain 1 is controlled by the length dimension produced by the support sleeve 15, thereby enabling the support roller 26 to run on a track at different distances from the basic chain 1.

[0032] Second Embodiment

[0033] Appendix Figure 5-6 In one embodiment of the present invention, by setting the limiting component 3, the stability of the base chain 1 during operation is further improved, thereby reducing the vibration of the base chain 1 itself and improving the stability of the support component 2 rolling on the track on which the base chain 1 is installed.

[0034] Compared with the first embodiment, the second embodiment is further optimized in that it also includes a limiting component 3. The limiting component 3 includes a support frame 31 and support plates 32 at both ends of the top of the support frame 31. The support frame 31 is triangular. A first bolt 34 is detachably installed inside the bottom end of the support frame 31 by means of a nut. A first support rod 33 is fixedly connected to one side of the first bolt 34. An auxiliary roller 35 is rotatably installed on the side of the first support rod 33 away from the first bolt 34.

[0035] During the transmission of the basic chain 1, the support roller 26 rolls on the track on which the basic chain 1 is installed. Through the setting limit component 3, the auxiliary roller 35 rolls at the bottom of the track on which the basic chain 1 is installed. Through the support roller 26, the hopper is supported. At the same time, through the limit of the auxiliary roller 35 at the bottom of the track and the support roller 26 at the top of the track, the left and right swing and up and down movement of the basic chain 1 during operation are avoided, thereby achieving the smooth operation of the basic chain 1 and adapting to more complex transmissions.

[0036] By selecting the height of the support plate 32, the distance between the auxiliary roller 35 and the support roller 26 is controlled, thereby enabling the auxiliary roller 35 and the support roller 26 to adapt to support tracks of different thicknesses.

[0037] The lifting block 242 is fixedly connected to a second support rod 36 at one end away from the support roller 26. A second bolt 37 is fixedly connected to one side of the second support rod 36. The upper end of the support plate 32 is detachably installed on the outer surface of the second bolt 37 by a nut. The length of the second support rod 36 is the same as the length of the first support rod 33. By controlling the production length of the second support rod 36 and the first support rod 33, it is possible to adapt to tracks of different widths, thereby improving the adaptability of the device.

[0038] Third Embodiment

[0039] Appendix Figure 7-8 In one embodiment of the present invention, the support sleeve 15 is used to improve the stability of the base chain 1, while allowing the operator to quickly understand the tension of the base chain 1, so as to adjust the tension of the base chain 1 or replace the base chain 1 in a timely manner.

[0040] Compared with the first and second embodiments, the third embodiment is further optimized in that: the support sleeve 15 includes a limiting plate 151, and two support rings 152 are fixedly installed on one side of the limiting plate 151. The two support rings 152 are respectively sleeved on the outer surface of one end of the two connected pins 12. The limiting plate 151 is located on the side away from the base chain 1. An arc-shaped limiting groove 153 is opened at the top of one end of the limiting plate 151. The arc-shaped limiting groove 153 is movably sleeved on the outer surface of the fixed shaft 25. The width of the arc-shaped limiting groove 153 is greater than the diameter of the fixed shaft 25, and there is a gap between it and the fixed shaft 25. During the transmission process, the base chain 1 utilizes the arc shape of the arc-shaped limiting groove 153, and the fixed shaft 25 inside the other side of the support component 2 moves freely in an arc shape inside the arc-shaped limiting groove 153. This avoids interference between the two support components 2 during the transmission process of the base chain 1, which would affect the transmission of the base chain 1.

[0041] When the base chain 1 has been in operation for a long time, it will extend, and the distance between the two support components 2 will gradually increase. When the fixed shaft 25 inside one support component 2 comes into contact with the inner wall of the arc-shaped limiting groove 153, friction will occur and a sound will be emitted to remind maintenance personnel to replace the base chain 1 in time, or adjust the tension of the base chain 1 to improve the smoothness of the operation of the base chain 1, avoid the phenomenon of the base chain 1 jumping out of the groove or jumping out of the tooth, and improve the transmission efficiency.

[0042] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
