Description

Belt buffer protection device for belt conveyor and method of use

Technical field

The present invention relates to the field of support frames or protective frames or covers for ring-shaped load carriers or traction elements of belt or chain conveyors, specifically a belt buffer protection device for belt conveyors and a method of using the same.

Background technique

The belt conveyor is a commonly used transmission mechanism, consisting of a belt tension hoop mounted on a roller. The current belt conveyor has very weak protection for the belt. When the belt conveyor is used in the smelting plant, various waste materials fall directly from the hopper onto the belt, especially rod-shaped materials, which are easy to pierce the belt and the material after piercing. The material continues to be transported by the belt. When it is transported to the next roller, the material is stuck by the roller, and the belt continues to transport. As a result, the belt in the transport state is torn by the stuck material, causing the belt to be damaged or even scrapped.

A belt buffer protection device for a belt conveyor, including a roller and a belt. There are at least two groups of rollers, each group including three rollers. The three rollers in each group are arranged end to end in sequence and are all rotatable. On the frame, the outer ends of the rollers at both ends are tilted upward, so that each group of three rollers forms a trough shape with an upward opening. Each group of rollers is arranged parallel to each other in turn, and the belt is wound around each group of rollers in a ring shape. Match the shape of each set of rollers,

Its characteristics are: it also includes sprockets, chains and protective plates.

In each set of rollers, a sprocket is fixed at both ends of the middle roller. The two chains are annular and wrapped around each sprocket on one side of the roller. The protective plate is made of the same number of links as the chain. The two ends of the bottom of each protective unit are respectively fixed on a link of a chain. Each protective unit is parallel to each other and is located inside the belt. The top of each protective unit is flush with a gap between each other. .

The belt buffer protection device for belt conveyors is characterized by: the cross section of the protection unit is T-shaped, the bottom of the vertical part of the protection unit is fixed on the link of the chain, and the horizontal part of the protection unit is facing the belt. medial side.

The belt buffer protection device for belt conveyors is characterized in that when the links of the chains corresponding to the protection units are horizontal, the gaps between adjacent protection units are not greater than mm.

. The method of using the belt buffer protection device for the belt conveyor as claimed in any one of claims 1 to 1, characterized in that: the following steps are implemented in sequence:

i. Installation:

i-1 Install the belt conveyor: Take every three rollers as a group. The three rollers in each group are arranged end to end and are rotatably installed on the frame. The outer ends of the rollers at both ends are tilted upward. Make each group of three rollers form a trough shape with an upward opening. Each group of rollers is arranged parallel to each other in turn. The belt is wound around each group of rollers in a ring shape and matches the shape of each group of rollers;

i-2 Install protective device: A sprocket is fixed at both ends of the middle roller in each group of rollers. Both chains are ring-shaped and wrapped around each sprocket on one side of the roller. The protective plate is made of It is composed of protective units with the same number of links as the chain. The two ends of the bottom of each protective unit are respectively fixed on one link of a chain. Each protective unit is parallel to each other and is located inside the belt. The tops of each protective unit are aligned. flat with gaps between them;

ii. Transportation: The belt drives the roller to rotate, and the rotation of the roller drives the protection unit to move synchronously with the belt through the rotation of the sprocket and the movement of the chain;

iii. Protection: When materials fall onto the belt, the protective plate on the inside of the belt supports and protects the belt to prevent the belt from being punctured.

The invention adds a protective plate inside the belt to support and underpin the belt, thereby avoiding damage to the belt after being directly hit by materials. It has the following beneficial effects: simple structure, easy use, easy installation, and good protection. Extends belt life.

Example

A belt buffer protection device for a belt conveyor, including a roller 1, a belt 2, a sprocket 31, a chain 32 and a protective plate 4, as shown in Figures 1 and 2. The specific structure is:

There are at least two groups of rollers 1. Each group includes three rollers 1. The three rollers 1 in each group are arranged end to end and are rotatably installed on the frame. The outer ends of the rollers 1 at both ends are inclined upward. , so that each group of three rollers 1 forms a trough shape with an upward opening, each group of rollers 1 is arranged parallel to each other, and the belt 2 is wound around each group of rollers 1 in order and matches the shape of each group of rollers 1;

In each group of rollers 1, a sprocket 31 is fixed at both ends of the middle roller 1. The two chains 32 are annular and wrapped around each sprocket 31 on one side of the roller 1. The protective plate 4 is composed of The chain 32 is composed of protective units 41 with an equal number of links. The two ends of the bottom of each protective unit 41 are respectively fixed on one link of a chain 32. Each protective unit 41 is parallel to each other and is located inside the belt 2. The tops of the protective units 41 are flush with gaps between them.
