Description

Technical Field

[0001] This invention relates to the field of production repair related to conveying equipment, specifically a loading platform after conveyor chain repair and its usage method. Background Technology

[0002] Chains are commonly used tools for power transmission or object transportation in people's lives. However, chains will inevitably suffer some damage after long-term use and wear, requiring timely repair and maintenance.

[0003] Chain maintenance and repair inevitably require first removing the chain from the two sprockets for processing, and then reinstalling it afterward. In practice, to facilitate installation, the two sprockets need to be fixed in specific positions to ensure easy chain mounting, but this is often difficult and complex in practice. Summary of the Invention

[0004] To address the need for securing sprockets during manual chain installation, this invention proposes a loading platform for a repaired conveyor chain and its usage method.

[0005] The technical problem to be solved by this invention is achieved by the following technical solution:

[0006] A loading platform for a repaired conveyor chain includes a platform base with two mounting platforms. A main positioning rod is welded to the center of each mounting platform, and auxiliary positioning rods are located to the left and right of the main positioning rod. A lifting controller is connected to each of the two auxiliary positioning rods. A pressing and fixing assembly is also installed on each auxiliary positioning rod. Each mounting platform is used to position and install a sprocket, facilitating chain installation. The main positioning rod is used to engage with the center hole of the sprocket for primary positioning. The auxiliary positioning rods are used to engage with the eccentric holes on the sprocket. The lifting controller is used for auxiliary connection. The pressing and fixing assembly is used to automatically fix the sprocket in the vertical direction.

[0007] Furthermore, of the two mounting platforms, the mounting platform on the left is fixedly mounted on a platform base, and the platform base is provided with a bottom groove for sliding the mounting platform on the right. That is, the distance between the two mounting platforms is adjustable, which in turn allows for adjustment of the distance between the two sprockets. This not only accommodates the installation of chains of different lengths but also facilitates automatic adjustment of chain tension during installation.

[0008] Furthermore, the platform base is also equipped with a type I hydraulic cylinder connected to the mounting platform located on the right side. That is, the sliding of the mounting platform on the right side can be automatically controlled.

[0009] Further, the upper part of each mounting platform is provided with a through slot for vertically slidingly mounting each auxiliary positioning rod.

[0010] Further, the lifting controller is composed of a cylinder mounted on the lower part of the mounting platform and a collection plate connected to the cylinder, and the collection plate is connected to the corresponding two auxiliary positioning rods. That is, the lifting of the auxiliary positioning rods can be automatically controlled by the cylinder.

[0011] Further, a cross slot is formed in the upper center of each auxiliary positioning rod, and inclined slots are formed in the corresponding two opposite inner side walls of the front, rear, left and right parts of the cross slot. This structure is a necessary condition for subsequent fixation of the chain wheel.

[0012] Further, the pressing and fixing assembly comprises a cylindrical rod slidingly mounted in each inclined slot and a lateral pressing plate connected to the two corresponding cylindrical rods, and the four lateral pressing plates are respectively located in the front, rear, left and right parts of the cross slot. The lateral pressing plate can be controlled to rise and fall and extend and retract towards the inner and outer sides of the cross slot to realize the fixing function.

[0013] Further, the pressing and fixing assembly further comprises a type II hydraulic cylinder mounted at the bottom end of the cross slot and a composite plate connected to the type II hydraulic cylinder, and the composite plate is matched with the corresponding four lateral pressing plates. That is, the composite plate can be lifted under the drive of the type II hydraulic cylinder.

[0014] Further, the composite plate is integrally composed of two cross plates and an associated block located at the center of the two cross plates, and the lower two ends of each lateral pressing plate are correspondingly abutted against the two cross plates. That is, through the abutting action, all the lateral pressing plates can be lifted together with the composite plate, so that the pressing and fixing of the chain wheel can be achieved.

[0015] The beneficial effects of the present application are:

[0016] The present application can adjust the distance between the two chain wheels to adapt to the installation of chain of different lengths, and can also automatically adjust the tension of the chain. The present application can position the chain and automatically fix the rotation degree, the up-down freedom degree, and can accurately fix the chain wheel, which is convenient for subsequent installation of the chain.
