A grille anti-deformation device

Abstract

An anti-deformation device for a grille belongs to the field of monitoring. A spring wire rope is arranged on the side plate between two adjacent grids; the spring wire rope is arranged in a suspended state between the two adjacent grids; An infrared limit switch composed of an infrared receiver; the output contact of the infrared limit switch is connected to the corresponding I / O terminal of the PLC; When large pieces of material are placed, the spring wire rope is pressed down to the maximum hanging state, and the corresponding infrared limit switch is triggered to send out a monitoring action signal. It realizes the rapid alarm and timely cleaning after the blockage of bulk materials, which can prevent the problem that the TR trolley walking frame pulls and deforms the grille during the walking process due to the untimely cleaning of the bulk materials, and reduces equipment downtime. time to ensure the stable operation of the coal silo equipment. It can be widely used in the field of belt conveying of large materials.

Description

technical field [0001] The invention belongs to the field of monitoring, and in particular relates to a grille deformation preventing device used on a material conveying machine. Background technique [0002] In the design of existing material conveying machinery (eg, belt conveyor, etc.), a blanking hopper is usually provided above a silo (also called a silo) for introducing the material on the belt conveyor into the silo. [0003] In order to prevent large pieces of material from blocking the entrance of the silo, a set of grilles is usually installed at the entrance of the silo, so that the contact between the material and the grille can be used to break or break up agglomerated or large materials, preventing It blocks the entrance of the silo, or prevents the TR trolley (ie the mobile relay trolley) from walking due to the existence of large pieces of material. [0004] At present, due to the limitation of the screening of bulk materials in the upstream system of the si...

AI Technical Summary

Problems solved by technology

By setting a spring steel wire rope between two adjacent grids and using an infrared detection switch to monitor the displacement of the spring steel wire rope after being pressed down by a large piece of material, it realizes rapid alarm and timely cleaning after the large piece of material is blocked, and also It can prevent the problem of pulling and deforming the grid during the walking process of the TR trolley traveling frame caused by the untimely cleaning of large materials, reducing the downtime of equipment failure and ensuring the stable operation of coal silo equipment
