Description

Belt tensioner

Technical Field

The utility model relates to a band conveyer field especially relates to a belt tightener.

Background

In a belt conveyor, two ways are generally adopted to ensure belt tensioning, one is to make a guide roller move to increase the distance between the guide roller and a driving roller to realize belt tensioning, and the other is to set a tensioning roller which is adjusted downwards to realize belt tensioning as shown in fig. 1.

The current way of tensioning roller down adjustment is to move the tensioning roller down and then secure the tensioning roller by fasteners to maintain position. This approach has the following disadvantages: 1. the position of the tensioning roller is fixed, the tensioning roller cannot move upwards to loosen the belt, and if large materials fall into the belt, the belt conveyor is blocked or the belt is torn; 2. the mode is adjusted once, the belt is extended after being used for a period of time, and after the tension degree is reduced, the belt needs to be adjusted again, so that the belt is relatively complex.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: a belt tensioner is provided which is convenient to tension and has a certain flexibility.

The technical scheme adopted for solving the problems is as follows: the belt tensioning device comprises a tensioning roller and a tensioning roller moving device, the tensioning roller moving device comprises two guide devices, a cross beam and a counterweight container, the two guide devices are respectively positioned at two ends of the tensioning roller, each guide device comprises a vertically arranged guide column and a sliding block capable of moving up and down along the guide column, the tensioning roller is connected with the sliding blocks of the two guide devices, the cross beam is positioned below the tensioning roller and connected with the sliding blocks of the two guide devices, and the counterweight container is connected with the cross beam.

Further, the method comprises the following steps: the number of the counterweight containers is two, and the two counterweight containers are respectively positioned at the outer sides of the two guide devices.

Further, the method comprises the following steps: the belt tensioner comprises a shield which is located above the tensioning roller and is connected to the slides of the two guides.

Further, the method comprises the following steps: be provided with the guide way on the guide post, the slider includes slider main part and separation blade, and the cross sectional shape of slider main part is the T shape, and the slider main part includes slider bottom plate and slider sand grip, and the slider sand grip passes the guide way, and the separation blade is connected with the slider sand grip.

The utility model has the advantages that: 1. when the tension degree of the belt needs to be adjusted, the counterweight is added into the counterweight container, and the gravity of the counterweight enables the tensioning roller to move downwards to tension the belt. The utility model discloses increase and decrease counter weight can adjust belt rate of tension, and it is very convenient to adjust.

2. The position of the tensioning roller is not fixed, and if a large material falls into the belt, the belt can enable the tensioning roller to move upwards, so that the stress of the belt is not obviously increased, and the belt can be prevented from being damaged.

3. When the belt is used for a period of time to stretch, the balance weight enables the tensioning roller to move downwards further, so that automatic tensioning can be realized, the long-term use of the belt is ensured, and the tension degree is still basically kept unchanged.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 2: the belt tensioning device comprises a tensioning roller 1 and a tensioning roller moving device, the tensioning roller moving device comprises two guide devices 2, a cross beam 3 and a counterweight container 4, the number of the guide devices 2 is two, the two guide devices 2 are respectively positioned at two ends of the tensioning roller 1, each guide device 2 comprises a guide column 21 vertically arranged and a sliding block 22 capable of moving up and down along the guide column 21, the tensioning roller 1 is connected with the sliding blocks 22 of the two guide devices 2, the cross beam 3 is positioned below the tensioning roller 1 and connected with the sliding blocks 22 of the two guide devices 2, and the counterweight container 4 is connected with the cross beam 3.

When the tension degree of the belt needs to be adjusted, the counterweight is added into the counterweight container 4, and the gravity of the counterweight enables the tensioning roller 4 to move downwards to tension the belt. The weight may be a common weight, such as sand.

In order to avoid tilting of the tensioning roller 1, the number of counterweight containers 4 is two, the two counterweight containers 4 being located outside the two guides 2. The tensioning roller 1 can be ensured to be horizontal against tilting by adjusting the weight of the counterweight added by the two counterweight containers 4. The two counterweight containers 4 are respectively positioned at the outer sides of the two guide devices 2, and the counterweight containers 4 are not blocked by other parts of the belt conveyor, so that the addition of the counterweight is facilitated.

In order to prevent material from entering between the tensioning roller 1 and the belt and thereby causing a belt jam, the belt tensioning device comprises a hood 5, which hood 5 is located above the tensioning roller 1 and is connected to the sliding blocks 22 of the two guide means 2.

The specific structure of the guide 2 is preferably as follows: the guide post 21 is provided with a guide groove 211, the slider 22 comprises a slider main body 221 and a stop piece 222, the cross section of the slider main body 221 is T-shaped, the slider main body 221 comprises a slider bottom plate 2211 and a slider protruding strip 2212, the slider protruding strip 2212 passes through the guide groove 211, and the stop piece 222 is connected with the slider protruding strip 2212.
