Description

Apparatus for Adjusting Belt Serpentine of Belt Conveyor}

The present invention relates to a belt meandering device of a conveyor, and more particularly, it is possible to effectively adjust the meandering of the carrier or return side belt of the conveyor in a self-aligning manner, and in particular, the contact between the meandering belt and the guide roller is maintained. To prevent breakage of the guide rollers due to instantaneous contact (impact) of the meandering belts, while also preventing the fine particles from adhering to the transport, thereby improving the operability and extending the life of the device as a whole. It relates to a belt meandering device.

Steel mills use a significant amount of iron ore and coal as raw materials and fuel for blast furnaces. Usually, raw materials and fuels of such steel mills are mostly imported from foreign countries, so they are transported from docks to ships by unloading vessels.

Therefore, a large scale (distance) of raw and fuel transportation equipment, such as a belt conveyor, is installed and operated up to the yard (yard) of the steel mill, and a considerable scale belt conveyor is operated in the factory.

On the other hand, such a belt conveyor includes a belt that is transported in a caterpillar, and the belt is divided into a carrier belt on which a shipment is mounted and a return belt after the shipment is discharged.

By the way, the most problem in the operation of the belt conveyor in the steel mill is the belt meandering phenomenon in which the belt is transferred while being biased to one of the carrier roller and the return roller.

This meandering of the belt causes a drop of the transported goods, and thus, a drop of coal or iron ore due to the meandering of the belt causes pollution.

On the other hand, a known device for adjusting (preventing) the belt meandering is a self-aligning device which forcibly moves the belt in reverse direction during the meandering of the belt to guide the traveling path of the belt along the center of the conveyor.

For example, FIG. 10 shows a known conventional self-aligning device. However, in the belt conveyor 100 illustrated in FIG. 10, carrier rollers 130 supporting the carrier belt 120 are basically installed in the frame 110, and a return belt 140 is provided below the frame 110. Supporting return rollers 150 are arranged at predetermined intervals.

On the other hand, as shown in Figure 10, the self-aligning device 200 for adjusting the meandering of the known belt, the self-aligning stand 210 is installed, the carrier frame 130 supporting the carrier belt 110, the conveyor frame The support 220 connected to the 110 is rotatably mounted via the bearing member 220a.

In addition, the self-aligning stand 210 is provided with guide rollers 240 contacting the edges of the belt when the belt meanders through the connection bar 230.

Of course, the self-aligning device 200 in FIG. 10 shows only the portion 'A' in contact with the carrier side belt, but may be provided in the portion 'B' in contact with the return belt 140 only by adjusting the frame connection direction. .

Therefore, in the case of the conventional self-aligning device 200, when the meandering of the belt is generated, the meandering belt is pushed in contact with the guide roller 240, the self-aligning stand 210 is connected when the guide roller 240 is pushed A rotating shaft is assembled to the bearing member 220a and rotated about the shaft.

At this time, as the carrier roller 120 is inclined contact with the carrier belt 110, the friction force between the belt and the roller is changed, and eventually the meandering of the belt is adjusted while the belt is returned in the reverse direction of the meandering direction.

However, as shown in FIG. 10, in the case of the conventional self-aligning device 200, when the belt is normally progressed, for example, a gap G of about 50 mm is maintained between the belt edge and the guide roller. Therefore, when the belt meanders, the edge of the belt always impacts the guide roller 140 while being in instant contact (collision) with the guide roller.

Therefore, in the case of the conventional self-aligning device 200, the guide rollers 240 to adjust the meandering in contact with the belt which is substantially meandering were easily worn or damaged by impact so that the guide rollers had to be replaced periodically.

However, in view of the moving distance (length) of the belt conveyor in an actual steel mill, a considerable number of self-aligning devices 200 should be installed in the unit belt conveyor alone, so that the replacement costs of the guide rollers are considerable, There is a problem that excessively requires maintenance and maintenance, and the load of the operator due to the roller replacement is considerable.

Accordingly, the applicant of the present invention effectively adjusts the meandering of the belt of the conveyor, that is, the carrier belt or the return belt, in a self-aligning manner, while preventing the damage of the guide roller by the belt as much as possible to extend the life of the equipment. The present invention has been proposed.

The guide rollers 54 of the belt guide means 50 are subjected to a force that always maintains contact with the belt, that is, the return belt 140 in this embodiment.

For example, FIG. 5A illustrates a belt conveyed in a normal path where no belt meandering occurs, and FIGS. 5B and 5C illustrate a state in which the belt meanders to the right and the left, respectively, as shown in FIG. 5. When the belt is in any state, the guide rollers 54 of the present invention are supported while maintaining contact with the belt, and the self-aligning stand connected to the tie-rod 22 connected to the first link member 14 when the belt meanders ( Rotation of 210 is performed (self-aligning).

Therefore, the return roller 150 mounted on the self-aligning stand 210 increases and decreases the friction force with the belt while rotating when the belt meanders, and the meandering of the belt is adjusted.

On the other hand, the tie-rod 22 is connected between the first link member 14 and the self-aligning stand 210, so that the rotation width of the link member and the self-aligning stand 210 is the screw rotation of the tie-rod Can be adjusted by operation.

In addition, a fastening hole (unsigned) of the first link member 14 is fastened to the pivot shaft 18, and is driven to rotate as shown in FIG. 5 around the pivot shaft, and the first link member is fixed to the upper portion of the pivot shaft. The stop ring 24 can be fastened.

On the other hand, more preferably, as shown in Figures 3 and 4, the outer end of the pivot shaft is fixed to the first link member 14, the upper end of the auxiliary elastic body is fixed to the first support member 12 20, that is, a coil spring may be provided.

Therefore, the auxiliary elastic body applies a rotational force to the first link member, the first elastic body 16, the coil spring of the elongated structure described above to apply the main rotational force of the first link member, the auxiliary elastic body is the first The shock upon the belt contact with the guide roller 54 of the guide means connected with the link member will further cushion or allow the application of a fine rotational force.

On the other hand, although not shown in the drawings, the tie-rod 22, one end of the first link member 14 is connected to the hinge block (B) is welded and connected to the section steel structure constituting the self-aligning stand Can be.

Next, the belt guide rollers 54 of the belt guide means 50 are rollers via a bearing on a support plate 52 which is assembled to the other end of the first link member 14 via a pin P so as to be rotatable. A shaft (unsigned) may be provided to be idling.

Thus, since the support plate is rotatably assembled at the other end of the first link member, the guide rollers can guide more stably and maintain contact in response to the widthwise movement along the belt meandering.

On the other hand, the first link member 14 may be provided by bending or casting a plurality of link members in accordance with the belt contact position of the guide roller, having a height difference.

However, as described above, the first belt-adaptive connecting means 10 described above has a structure in which the first elastic member 16 and the first link member fastening portion of the pivot shaft are exposed to the outside, and thus are transported through the belt. If fine particles are easily generated according to the nature of the transported material, the fastening or pivoting part or the coil spring of the elastic body may be stuck and fixed, and thus the belt meandering may be impossible.

Therefore, the second belt-type connection means 30 described below is a form that prevents such a problem.

That is, FIGS. 6 to 8 show the apparatus of the second embodiment including the second belt-compatible connecting means 30 according to the invention.

For example, as shown in Figures 6 to 8, the second belt-adaptive connecting means 30 of the present invention is of a closed type provided to the second support member 32 connected to the conveyor frame 110. It may be configured to include a second link member 36 rotatably associated between the frame and the belt guide means with the rotation force applying means 34 as an axis.

At this time, in the second belt-coupling connection means 30 of the present invention, like the first belt-coupling connection means 10, the second link member 36, via the tie-rod (22) It is connected to the self-aligning stand 210 of the conveyor side described in detail above, the overall shape of the second link member may also be provided in the form of 'B' similar to the first link member.

On the other hand, in the second belt-coupling connection means 30 of the present invention, the second support member 32, as shown in Figure 8, is provided in a box structure different from the bending plate of the first support member The hermetic rotational force applying means 34 is provided in the inner space to prevent the fine particles or other foreign matters of the above-mentioned transport from being caught in the rotation center portion of the second link member.

In addition, the second link member, the tie-rod and the self-aligning stand, as in the first embodiment, it is natural that the connecting portion is rotatably fastened via the pins P and the hinge blocks B, respectively.

On the other hand, as shown in Figures 7, 8 and 9a, the rotational force applying means 34 of the second belt-adaptive connection means of the present invention is fastened to the second support member 32 and the second link member A second support member 41 rotatably assembled with a support shaft 41, and a second support member and a second link member connected between one end and the other end of the second support member and the second link member between the cap 42 disposed outside the support shaft and the support shaft. It may be composed of an elastic body 44.

At this time, as shown in Figure 9a, the upper end of the support shaft 41 is fixed to the second support member 32 with a screw 41b, the lower end of the support shaft 41 is the second link member 36 ) And the pin 41a assembled to the assembly plate 40 assembled thereon is fastened.

In addition, since the upper end of the coil spring that is the second elastic body 44 is connected to the second support member side, and the lower end of the coil spring is fixed to the assembly plate 40 on the second link member 36 side, respectively, 2 and 5, when the meandering of the belt occurs and the guide roller moves in the widthwise movement of the belt, the coil spring of the second elastic body is twisted or loosened to the second link member. By applying rotational force, the guide roller maintains contact between the belt and the guide roller even when the belt meander is generated left or right.

On the other hand, the cap 42 surrounds the second elastic body 44 of the rotational force applying means to prevent the fine particles or foreign matter from being caught while being caught in the coil spring at the source.

7, 8 and 9b, the rotational force applying means 34 of the present invention may be provided in another structure, for example, to the second support member 32 described above in detail. The support shaft 41 is fastened and the second link member 36 is rotatably assembled, and the support shaft is inserted, and the rotating hole 46 fixed to the second support member is fastened to the second link member. It may be provided including a rubber block 48 that is fixed while providing a rotational force.

Accordingly, the rubber block 48 is fixed to the link member, and since the support shaft 41 fixed to the support member side is fitted to the rotary hole 46, the guide roller moves in the belt meandering of the second link member. In this case, the rubber block 48 is compressed in a clockwise or counterclockwise direction. When the applied force is removed, the rubber block is returned to its original shape by the elastic force of the rubber itself. To the position.

That is, even if the belt moves, the belt contact of the guide roller is maintained by applying the rotational force of the second link member.

In this case, the first and second link members 14 and 36 in the first and second belt-coupling connection means are guide rollers with belt movement force when the belt meanders to the right side as shown in FIG. And the first and second link members are forcibly pulled by the first elastic body 16 or twisted by the second elastic body 44 or by the clockwise compression of the rotary block and the rotary block, the rotational force is applied conversely, and thus the belt meandering is adjusted. The guide roller is kept in contact with the belt during operation.

On the contrary, when the belt meanders to the left side as shown in FIG. 5C, the elastic force of the elastic body and the rubber block is applied to the first and second link members to maintain the belt contact of the guide rollers while rotating as the belt moves.

Of course, the self-aligning stand during the rotation of the first and second link members in the apparatus of the present invention is also driven to rotate the bearing member about the axis so that the belt meandering is adjusted by the rotation of the carrier roller or the return rollers.

Meanwhile, as shown in FIG. 8, openings 32a may be formed at both sides of the second support member of the box structure to provide a space in which the second link member 36 rotates. The assembly plate 40 is for facilitating non-assembly of the second link member with the rotational force applying means 34, and for this purpose, bolting is performed on both sides.
