Method for detecting broken chains of swaying rack chain fall

Abstract

The invention discloses a method for detecting broken chains of a swaying rack. A swaying rack is provided with a plurality of chains, wherein the chains are connected with a drive motor; the drive motor is connected with one PLC (Programmable Logic Controller); the PLC controls the drive motor to drive the chains to move back and forth; a steel wire rope is arranged below the chains; one end of the steel wire rope is fixed, and the other end of the steel wire rope is connected with a steel plate capable of sliding up and down via one steering wheel; one side of the steel plate is provided with a proximity limit sensor corresponding to the steel plate; and the proximity limit sensor is connected with the PLC controller. According to the device, maintenance staff can be reminded of overhauling chains on the swaying rack in time so as to avoid the problems of pulling deformation, falling and destroy of a chain track in a broken chain, thereby effectively shortening chain overhauling time, saving manpower and materials, lowering production cost, improving overhauling efficiency and ensuring normal production.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for detecting the disconnection and falling off of a chain on a traversing platform. Background technique [0002] The finishing and traversing bench of Baosteel Heavy Plate Plant is an important equipment used in the production of thick plates, and it is mainly used to transport plates of different specifications cut by cut-to-length shears. There are several chains on the traversing platform, and the plates are placed on the chains, and the chains are driven by the drive motor to move to transport the plates. In the production process, since the chain on the traversing platform runs continuously every day, the key equipment on the traversing platform-the chain often appears damaged and deformed to varying degrees, and it is inevitable that the long-term operation will There is a problem with the chain breaking off.

In the production process, since the chain on the traversing platform runs continuously every day, the key equipment on the traversing platform-the chain often appears damaged and deformed to varying degrees, and it is inevitable that the long-term operation will There is a problem with the chain breaking and falling off

[0003] When one of the chains on the traversing platform breaks off, due to the large number of chains, the operators in the operating room of the traversing platform cannot find the fault in time

However, due to the limited downtime and many restorative maintenance items in the restorative repair work performed by maintenance personnel twice a month during the scheduled repair period, it can generally only guarantee the basic normal production tasks of the traversing gantry, and cannot be comprehensive and thorough. Effectively detect and discover potential failures after the chain breaks off

Such long-term accumulation will not only cause more and more disconnected and fallen chains, but also when the disconnected and fallen chains run together with other chains, the chain rails in the broken chains will be pulled and deformed, causing them to fall off or even damaged.

Once the traversing gantry can no longer operate normally, because there are many damaged chains and the damage is serious, it is necessary to organize a large amount of manpower and material resources for maintenance operations, and each maintenance takes a long time, which will affect the production. affect normal operation
