Description

Technical Field

[0001] The utility model relates to the field of belt conveying, in particular to a belt deviation correcting idler mechanism. Background Art

[0002] Due to advantages such as large load capacity, convenient layout, and low purchase cost, belt conveyors are widely used in the material transportation work of many fields. Especially for the coal produced underground, belt conveyors are the main transportation equipment.

[0003] However, there are certain technical drawbacks when the belt conveyor is running. Especially, the belt is very prone to deviation. In the prior art, the common method for dealing with belt deviation is to adjust the idler, making the idler originally perpendicular to the belt tilt towards the deviation direction, that is, giving the running belt a thrust towards the rectifying direction to gradually restore it to normal. However, for the underground working conditions, the adjustment of belt idlers is very inconvenient, and there are greater risks in the implementation process. For the above problems, there is still a lack of corresponding solutions. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a belt deviation correcting idler mechanism with a clever structure. After the belt deviates, it can follow the belt to turn, continuously provide an opposite thrust for the offset belt during the belt running process, cooperate with the deviation correcting wheel and the tension spring to gradually rectify the belt, and does not require manual participation.

[0005] The device includes a chassis, and the chassis is the assembly basis of the device;

[0006] A rotary mechanism is rotatably arranged on the chassis;

[0007] A roller support is fixedly arranged on the rotary mechanism;

[0008] Rollers are arranged on the roller support. On both sides of the roller support, deviation correcting wheels inclined towards the middle of the rollers are respectively arranged;

[0009] A tension spring is further arranged between the rotary mechanism and the chassis.

[0010] The achieved effect is that after the belt deviates, it will drive the partial deflection of the roller support, that is, drive the roller to deflect. As the belt deflects, its edge contacts the deviation correcting wheel, and the deviation correcting wheel rotates in the opposite direction to the belt deviation direction, that is, rotates in the opposite direction based on the rotational connection of the rotary mechanism, and drives the roller to make its rotation direction obliquely cross with the straight running direction of the belt, that is, continuously provide a rectifying force for the belt to return to normal. In this case, the deviation correcting wheel assists the obliquely positioned roller to provide a rectifying force for the belt, and the tension spring part can provide a pulling force for the rotary mechanism to return to its original position and make the roller part return to normal again, ensuring the continuous and stable operation of the device.

[0011] The beneficial effects of the present utility model are as follows: The present utility model is ingeniously structured and can reverse the rotation mechanism after the belt deviates. Due to the reverse deflection of the rotation mechanism, the rotation direction of the idler is relatively crossed with the running direction of the belt, providing a thrust for the idler to return to the correct position. This implementation process eliminates the need for manual participation, improves operation safety, and has great value for safety promotion. Brief Description of the Drawings

[0016] The realization of the purpose, functional features, and advantages of the present utility model will be further described in conjunction with the embodiments with reference to the drawings. Specific Embodiments

[0017] Refer to Figure 1 , Figure 2 , a belt deviation correcting idler mechanism according to the present utility model includes a chassis 6, and the chassis 6 is the assembly base of this equipment;

[0018] A rotation mechanism 5 is rotatably arranged on the chassis 6;

[0019] An idler bracket 2 is fixedly arranged on the rotation mechanism 5;

[0020] An idler 7 is arranged on the idler bracket 2, and deviation correcting wheels 1 inclined towards the middle of the idler 7 are respectively arranged on both sides of the idler bracket 2;

[0021] A tension spring 4 is further arranged between the rotation mechanism 5 and the chassis 6.

[0022] The achieved effect is that after the belt deviates, it will drive partial deflection of the idler bracket 2, that is, drive the idler 7 to deflect. As the belt deflects, its edge contacts the deviation correcting wheel 1, and the deviation correcting wheel 1 rotates in the opposite direction to the belt deviation direction, that is, based on the rotational connection of the rotation mechanism 5, rotates in the opposite direction, and thereby drives the idler 7 to make its rotation direction obliquely cross with the straight running direction of the belt, that is, continuously provides a deviation correcting force for the belt to return to the correct position. In this case, the deviation correcting wheel 1 assists the obliquely - positioned idler 7 to provide a deviation correcting force for the belt, and the tension spring 4 can provide a pulling force for the rotation mechanism 5 to return to its position and make the idler 7 partially return to the correct position, ensuring the continuous and stable operation of the equipment.

[0023] Example 1, the belt deviation correcting idler 7 mechanism is arranged at intervals within the belt running unit, that is, at least one or more belt deviation correcting idler 7 mechanisms are arranged within the belt running unit. That is to say, this device is a deviation correcting device arranged inside the belt conveyor, and the remaining idler 7 mechanisms are fixed existing technology idler 7 mechanisms.

[0024] Example 2, the idler support 2 is in the form of a curved rod bent at both ends, and there are three idlers 7 in total, which are respectively arranged on the bent sections on both sides and the straight section in the middle thereof.

[0025] The effect achieved thereby is that the belt is concave in the middle, avoiding coal spillage.

[0026] Example 3, the deviation correcting wheel 1 includes an assembly bracket 11, and a deviation correcting wheel 1 is rotatably arranged on the upper part of the assembly bracket 11;

[0027] The assembly bracket 11 is provided with pin holes in an array; both sides of the idler support 2 are respectively provided with pin holes in an array;

[0028] The assembly bracket 11 and the idler support 2 are fixedly connected through a pin locking connector.

[0029] Preferably, the pin locking connector is a U-shaped pin and a bolt, that is, the rod part of the U-shaped pin is a screw rod, and it is in the form of being fastened with a bolt. That is, the assembly bracket 11 and the idler support 2 are fixed through the U-shaped pin, and the assembly angle is ensured thereby.

[0030] The effect achieved thereby is that the deviation correcting wheel 1 is close to the edge of the belt, and provides an opposite thrust thereto when the belt deviates, assisting the obliquely arranged idler 7 to correct the belt.

[0031] Example 4, both sides of the rotary mechanism 5 are respectively provided with a tension spring assembly base 3, and the tension spring 4 is arranged on the tension spring assembly base 3 and the outer wall surface of the rotary mechanism 5; and the two tension springs 4 are arranged oppositely.

[0032] The effect achieved thereby is to provide or maintain a tension for the rotary mechanism 5 taking the straight direction of the idler support 2 as the standard during the process of the belt gradually correcting and during the operation of the belt.

[0033] Example 5, the rotary mechanism 5 is a bearing.
