Description

Central axis moving belt conveyor meandering device {APPARATUS FOR AUTOMATICALLY CORRECTING BIAS MOVEMENT OF BELT CONVEYOR}

The present invention is a belt conveyor that is widely used as a means of transporting ore or other materials due to the meandering of the belt ore is poured into the outside of the belt and the belt is in contact with the structure is a phenomenon that the belt is broken or damage to the equipment and structures It relates to a belt conveyor meandering device for preventing the.

Belt conveyors, which are devices that efficiently transport ore, frequently cause the belt to meander due to various reasons such as excessive transport of ore, unbalanced ore, ore attached to rollers, etc. In this case, the ore is a belt conveyor. It is necessary to adjust the meandering of the belt from time to time because the belt is broken or the equipment structure is damaged while it is driven out of the outside or the belt and equipment structure are in contact with each other.

In general, when the belt meanders, the meandering of the belt is controlled by using a roller. For example, when the belt is biased to the left toward the direction in which the belt proceeds, the roller is turned to the right so that the belt in the opposite direction to be biased contacts the roller first. . That is, since the running of the belt is moved to the side where the roller first contacts, the roller is moved in the opposite direction to which the belt is biased according to the degree of bias.

In this case, the wider the area in which the roller and the belt contact, the faster the movement of the belt is moved, it is necessary to quickly contact a large area with the belt.

Since this work is done manually, if the amount of meandering is heavy or frequent during the transport of the ore, a lot of manual work is required, resulting in loss of time and manpower.

Therefore, the present invention is to continuously adjust the belt meander every time a meander occurs when the meander occurs in the belt conveyor continuously operated, and in particular, to make a quick meandering operation immediately when the meander occurs. A belt conveyor meandering device that prevents the outflow of ore due to meandering and prevents the belt from being damaged or damages to the structure of the structure. The purpose is to provide.

Hereinafter, with reference to the accompanying drawings, the present invention for achieving the above object will be described in detail.

In the present invention illustrated in Figs. 2 to 10, four traveling guide rollers 6-1 to 60-4 provided at both front and rear sides of the axial movement return roller set 70 meander when the belt 5 meanders. The belt (5) serves to guide the bending while maintaining a constant angle so as to push the cone rollers (73a, 73b) of the axial movement return roller. Therefore, the axial movement return roller 71 is automatically pushed in the opposite direction that the belt 5 meanders without an external power source.

The axial movement return roller 71 is supported through a roller bracket 72 fixed to a hinge shaft 78 on a shaft 76 fixed to a base frame 72a by a bearing 77, and the roller bracket ( 72 has a form in which a part of the center is opened and mounted on the two rollers 74 and fixed by the two rollers. Therefore, when the cone rollers 73a and 73b on both sides are pushed to the left and right, the center shaft 76 It moves to a certain section based on).

In addition, since the four rollers 74 are supported by the hinge shaft 78 on the rotation shaft 76, the belt 5 meanders so that the center of gravity moves and the one side presses the roller bracket 72 according to the center of gravity. It is possible to move up and down, and when the belt 5 proceeds to push the shaft return return roller 71, the rotation shaft 76 is also able to rotate forward and backward.

The springs 79 and 79a installed on the left and right return roller brackets 72 of the rotary shaft 76 are rotated by the return roller brackets 72 when the belt 5 meanders and the cone rollers 73a and 73b are forced. The springs 79 and 79a on the conical rollers 73a and 73b that are applied while being moved are compressed and the opposite side is maintained in a normal state.

When the meandering adjustment of the belt 5 is completed, the contact between the conical rollers 73a and 73b and the belt 5 is not made, and thus the force for pushing the conical rollers 73a and 73b is lost and the return roller bracket 72 is one side. The return roller bracket 72 is gradually returned to its original state by the force of the spring 79a pressed by the rotary shaft 76 while being pushed back to prepare for the next meandering.

That is, the return roller bracket 72 is in contact with the rotary shaft 76 by attaching a friction reducing resin liner 73 to a portion where the return roller bracket 72 and the rotary shaft 76 are in contact. It is easy to move when reciprocating.

When the belt 5 meanders to one side in the state in which the device is installed as described above, the axial movement return roller 71 is pushed to the opposite side of the meandering side of the belt 5 by the guide roller. It is pushed in the opposite direction to the meandering, that is, left or right, and the center of gravity of the belt 5 is changed so that one side of the axis shift return roller 71 is pressed downward so that the opposite axis shift return roller 71 meanders. Is raised and at the same time, the shaft return return roller 71 is pushed in the direction in which the belt 5 proceeds, so that the roller on the opposite side, which rotates around the shaft 76, meanders first. Will come into contact.

As the rotational width of the roller increases due to the movement of the central axis of the shaft movement return roller 71, the contact time between the belt 5 and the roller is increased and the contact area is maximized. When the roller is raised, the belt 5 first In this case, the meandering time is maximized in any case because the meandering time is shortened by contact. The present invention induces the above interactions at the same time so that the area in which the axial movement return roller 71 contacts the belt 5 can be quickly obtained. A large amount can be secured so that the meandering of the belt 5 can be automatically adjusted quickly.

The technical configuration and operation of the present invention described above will be described in more detail.

In the central axis movement belt meandering device according to the present invention, the driving guide roller 60 is installed on the frame 3 of the belt conveyor return belt 5, but the belt 5 is easily rotated when the belt 5 is in contact with the bracket. Supported by the 62 and when the belt 5 meanders, the axial shift return roller is held at a constant angle so as to contact the roller 61 and smoothly push the conical rollers 73a and 73b of the axial shift return roller 71. Four rollers are formed before and after both sides of the 71 and are fixed to the frame 3 of the belt conveyor.

Install the axial movement return roller 71 on the frame 3 of the belt conveyor return belt 5, but install the rotary shaft 76 using the bearing 77 on the base frame 72a to rotate when the force is applied to one side. It is possible to change the center of gravity of the belt (5) by adding a roller bracket 72 is fixed to the hinge shaft 78 to the rotating shaft 76 has a structure that can be pushed down to one side down and the roller bracket (72) In the center part of the), the springs 79 and 79a are installed, and the resin liner 73 for reducing friction is mounted on the side, and two rollers 74 are provided at the bottom of the roller bracket 72 and two at the top. By adding the roller bracket 72 has a structure that is easy to flow left and right without being separated.

The roller bracket 72 is provided with a return roller 71 that rotates while supporting the belt 5, and conical rollers 73a and 73b that are rotated when the belt 5 contacts the ends of the return roller 71. However, when the belt 5 maintains a constant angle by the driving guide rollers 60-1 to 60-4, it maintains a constant angle so as to smoothly rotate while contacting the belt 5.

Fig. 5 is a plan view of a normal state in which the center axis moving meandering device of the present invention is installed and the belt 5 does not meander, and Fig. 7A is a plan view of a state in which the device is installed and the belt 5 meanders. to be.

When the belt 5 meanders as shown in FIG. 7A, the belt 5 comes into contact with the driving guide roller 60-1 provided at the front end of the axial movement return roller 71, and the belt is driven with the driving guide rollers 60-1, 60 provided at the front and rear ends. Maintaining a constant angle according to the installation angle of -2) is bent to push the cone roller (73a) of the axial movement return roller (71).

When the cone roller (73a) is subjected to the force to push the roller bracket 72 in the opposite direction, the shaft movement return roller 70 is pushed in the whole and the spring (79a) installed on the roller bracket 72 is pressed.

In addition, since the center of gravity is changed by moving the belt 5 while meandering, the axial movement return roller 71 is pressed down by the belt 5 in the meandering direction and at the same time the force in the direction in which the belt 5 proceeds. The roller bracket 72 is rotated in the direction in which the belt 5 proceeds.

When the belt 5 meanders as shown in FIG. 6, the axial movement return roller 71 is pushed up to the opposite side and rotates in the direction in which the belt 5 proceeds as shown in FIG. 7A. First comes into contact with the belt 5 on the opposite side that meanders.

In particular, when the width of the rotation of the roller 71 increases due to the movement of the central axis of the axial movement return roller 71, the time for contacting the belt 5 is increased and the effect of increasing the area is maximized. In this case, the meandering adjustment time is shortened by contacting first, and the effect of the meandering adjustment is maximized in any case.

When the meander is adjusted as shown in FIG. 7B, the axis movement return roller 71 maintains the current state and then meanders to the opposite side, thereby repeating the above-described action, thereby automatically adjusting the meander at all times.

When the meandering adjustment of the belt 5 is completed, the contact between the conical rollers 73a and 73b and the belt 5 is not made, and thus the force for pushing the conical rollers 73a and 73b is lost and the return roller bracket 72 is one side. The return roller bracket 72 is gradually returned to its original state by the force to which the spring 79a pressed by the rotary shaft 76 and the friction reducing resin liner 73 return to the original state. do.

As described above, the present invention utilizes its own force generated when the belt 5 meanders without an external power source by using the axial movement return roller set 70 and the driving guide rollers 60-1 to 60-4. The meandering of the belt 5 can be automatically and automatically adjusted faster than other devices regardless of the direction, and the meandering adjustment is simple and efficient with the advantages of easy configuration and easy maintenance of the equipment. It is to provide the effect that can achieve the original objective optimally and effectively.
