Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and particularly to a transmission chain and sprocket assembly for an elevator. Background Art

[0002] A bucket elevator is driven by a driving motor to rotate a sprocket. Under the action of the rotation of the sprocket, a plurality of buckets on the chain are driven to run, so as to realize the vertical conveying of materials. Its working principle is that a closed chain is wound around a first sprocket and a second sprocket, and a bucket is installed at a certain distance along the entire length of the conveying chain. During operation, the driving motor drives the conveying chain and the buckets to run through the first sprocket, realizing the vertical conveying of materials.

[0003] Due to the long-term heavy-load transmission of the transmission chain and sprocket of the elevator, the chain and sprocket are severely worn. Therefore, in order to ensure the stability of the elevator in lifting materials, it is necessary to replace the worn parts of the chain and sprocket. The chain is installed in a multi-section connection, and it is relatively convenient to replace the worn part. However, the hub and the tooth ring of the sprocket are fixed integrally. When the teeth on the tooth ring are worn, the entire sprocket must be replaced, which increases the cost of replacing the worn sprocket. At the same time, when replacing the sprocket, the sprocket also needs to be disassembled from the transmission shaft, which further increases the complexity of replacing the sprocket.

[0004] Therefore, there is an urgent need for a transmission chain and sprocket assembly for an elevator to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a transmission chain and sprocket assembly for an elevator to solve the problem that the teeth and the tooth ring of the sprocket are fixed integrally, resulting in inconvenient replacement of the teeth as mentioned in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A transmission chain and sprocket assembly for an elevator, including a chain body and a sprocket body. The sprocket body is composed of a hub and a tooth ring, and further includes an installation assembly arranged on the hub for detachably installing the tooth ring.

[0007] The installation assembly includes a fixed cavity opened on the hub. A plurality of fixing holes are opened on the side wall of the fixed cavity close to the tooth ring. Each of the fixing holes is connected with a mounting plate through a guiding assembly. A plurality of mounting holes are opened on the inner wall of the tooth ring close to the hub side. Each of the mounting holes is arranged to match the mounting plate. The fixed cavity is provided with a linkage assembly for synchronously moving each mounting plate.

[0008] Each of the mounting plates is arranged in a circular array.

[0009] The guiding component includes a guiding plate fixedly connected to the side of the mounting plate away from the gear ring. The guiding plate is slidably connected with two symmetrically arranged T-shaped rods, and one end of each of the two T-shaped rods is connected to the inner wall of the fixed cavity.

[0010] The linkage component includes a linkage ring rotatably connected to the bottom wall of the fixed cavity. A spiral strip is provided on the side of the linkage ring close to the mounting plate. A linkage plate is fixedly connected to the side of the mounting plate close to the spiral strip. The side of the linkage plate away from the mounting plate is slidably connected to the spiral strip. The hub is provided with a rotating component for rotating the linkage ring.

[0011] The rotating component includes a rotating rod rotatably connected to the hub. A gear is fixedly connected to the end of the rotating rod located inside the fixed cavity. A rotating ring is fixedly connected to the inner wall of the side of the linkage ring away from the gear ring. A toothed ring is fixedly connected to the side wall of the rotating ring, and the toothed ring is meshed with the gear.

[0012] The end of the rotating rod away from the gear penetrates through the hub and is provided with a rotating hole arranged in a regular hexagon.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] Through the arrangement of the mounting component, under the combined action of the linkage component and the rotating component, a detachable connection and installation between the hub and the gear ring are formed. When the teeth are worn, only the gear ring needs to be replaced, thereby improving the reuse rate of the hub, further reducing the replacement cost of the sprocket body, and when replacing the gear ring, it is not necessary to disassemble the hub from the transmission shaft to achieve the replacement of the gear ring, thus providing convenience for the replacement of the worn parts of the sprocket body.

Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1

[0024] Please refer to Figures 1-6 , a hoist drive chain sprocket assembly in the figure, including a chain body 101 and a sprocket body. The sprocket body is composed of a hub 102 and a gear ring 103, and further includes a mounting assembly provided on the hub 102 for detachably mounting the gear ring 103;

[0025] The mounting assembly includes a fixing cavity 201 opened on the hub 102. A plurality of fixing holes 202 are opened on the side wall of the fixing cavity 201 close to the gear ring 103. Each fixing hole 202 is connected with a mounting plate 203 through a guiding assembly. A plurality of mounting holes 204 are opened on the inner wall of the gear ring 103 close to the hub 102. Each mounting hole 204 is arranged to match the mounting plate 203. The fixing cavity 201 is provided with a linkage assembly for synchronously moving each mounting plate 203;

[0026] It should be noted here that: through the setting of the mounting assembly, under the combined action of the linkage assembly and the rotating assembly, a detachable connection and installation between the hub 102 and the gear ring 103 are formed. When the teeth are worn, only the gear ring 103 needs to be replaced, thereby improving the reuse rate of the hub 102, and further reducing the replacement cost of the sprocket body. Moreover, when replacing the gear ring 103, it is not necessary to disassemble the hub 102 from the transmission shaft, and the replacement of the gear ring 103 can be realized, thus providing convenience for the replacement of the worn parts of the sprocket body.

[0027] It should be emphasized that: during the transmission process of the sprocket, almost all the teeth will be evenly subjected to the force from the chain. Since the chain is continuously and evenly wound around the sprocket, each tooth will experience a similar meshing and disengaging process, and be subjected to similar forces and wear within the same time. This uniform force distribution makes the wear degree of each tooth tend to be the same.

[0028] Please refer to Figure 3 , and the mounting plates 203 in the figure are arranged in a circular array;

[0029] It should be noted here that: by arranging the mounting plates 203 in a circular array, the fixing of the mounting plates 203 to the gear ring 103 becomes more stable and balanced.

[0030] Please refer to Figure 5 and Figure 6 , and the guiding assembly in the figure includes a guiding plate 301 fixedly connected to the side of the mounting plate 203 away from the gear ring 103. Two symmetrically arranged T-shaped rods 302 are slidably connected to the guiding plate 301, and one end of each of the two T-shaped rods 302 is connected to the inner wall of the fixed cavity 201;

[0031] It should be noted here that: through the setting of the guiding assembly, it provides guiding and limiting functions for the movement of the mounting plate 203.

[0032] Please refer to Figure 5 and Figure 6 , and the linkage assembly in the figure includes a linkage ring 401 rotatably connected to the bottom wall of the fixed cavity 201. A spiral strip 402 is provided on the side of the linkage ring 401 close to the mounting plate 203. A linkage plate 403 is fixedly connected to the side of the mounting plate 203 close to the spiral strip 402. The side of the linkage plate 403 away from the mounting plate 203 is slidably connected to the spiral strip 402. The hub 102 is provided with a rotating assembly for rotating the linkage ring 401;

[0033] It should be noted here that: through the setting of the linkage assembly, it is convenient to drive the mounting plates 203 to move closer to or away from each other.

[0034] Working principle: When the bucket elevator is in use, the rotation of the chain body 101 is driven by the sprocket body, and then the rotation of each bucket is driven, thereby realizing the vertical transportation of materials;

[0035] Since the transmission chain body 101 and the sprocket body of the elevator are in transmission under heavy load for a long time, the transmission chain body 101 and the sprocket body are severely worn. Therefore, in order to ensure the stability of the elevator for material lifting, it is necessary to replace the worn parts of the transmission chain body 101 and the sprocket body. The transmission chain body 101 is installed in a multi-section connection, and it is relatively convenient to replace the worn part;

[0036] When it is necessary to replace the worn teeth on the sprocket body, first remove the chain body 101 from the sprocket body, and then use the rotating assembly to drive the linkage ring 401 to rotate. During the rotation of the linkage ring 401, the spiral bar 402 is driven to rotate. Then, under the interaction force between the spiral bar 402 and the linkage plate 403 and the guiding action of the guiding assembly, the installation plates 203 are driven to move closer to each other, so that the installation plates 203 are removed from the installation holes 204 on the tooth ring 103. At this time, the connection limit between the hub 102 and the tooth ring 103 is released;

[0037] After the connection limit between the hub 102 and the tooth ring 103 is released, the tooth ring 103 can be removed from the hub 102. Then, a new tooth ring 103 is sleeved on the side wall of the hub 102, and under the combined action of the rotating assembly and the linkage assembly, the installation plates 203 move away from each other, insert into the installation holes 204, and abut against the bottom wall of the installation holes 204. Thus, through the abutting action of the installation plates 203, the installation and fixation between the hub 102 and the tooth ring 103 are realized, forming a detachable connection and installation between the hub 102 and the tooth ring 103. When the teeth are worn, only the tooth ring 103 needs to be replaced, which improves the reuse rate of the hub 102, reduces the replacement cost of the sprocket body, and when replacing the tooth ring 103, the tooth ring 103 can be replaced without removing the hub 102 from the drive shaft, providing convenience for the replacement of the worn parts of the sprocket body.

[0038] Embodiment 2

[0039] Please refer to Figure 5 , this embodiment further illustrates Embodiment 1. The rotating assembly in the figure includes a rotating rod 501 rotatably connected to the hub 102. One end of the rotating rod 501 located inside the fixed cavity 201 is fixedly connected with a gear 502. The inner wall of the side of the linkage ring 401 away from the tooth ring 103 is fixedly connected with a rotating ring 503. The side wall of the rotating ring 503 is fixedly connected with a toothed ring 504. The toothed ring 504 and the gear 502 are meshed with each other. The end of the rotating rod 501 away from the gear 502 penetrates through the hub 102 and is provided with a rotating hole 505 with a regular hexagon setting;

[0040] It should be noted here that: through the setting of the rotating assembly, when rotating the linkage ring 401, an inner hexagon wrench is inserted into the rotating hole 505 on the rotating rod 501, and then by rotating the inner hexagon wrench, the rotating rod 501 is driven to rotate, and then the gear 502 at one end of the rotating rod 501 is driven to rotate. Thus, during the rotation of the gear 502, the linkage ring 401 is driven to rotate under the meshing and transmission action between the gear 502 and the toothed ring 504.
