Description

Recliner boom belt conveyor weight device prevents unevenness {AN WEIGHT APPARATUS FOR BELT CONVEYOR OF RECLAIMER}

The present invention relates to a belt conveyor installed in the boom (BOOM) of the reclaimer (RECLAIMER) to link the discharged pile to the ground belt conveyor side, in more detail, using the bucket of the reclaimer, the pile pile height when the raw material pile is released Even if the boom tilt due to the difference, the weight to adjust the belt always adjusts the tension of the belt constantly, thus uneven belt tension caused by the irregularity of the belt tension due to the weight bias. It relates to a boom belt conveyor weight device of the reclaimer is prevented one-sided so as to prevent.

In general, soft and raw materials transported by ships or wagons from steel mills are transferred to a belt conveyor to be deposited with steca. Such stacked ores and coal and other subsidiary materials are discharged using a reclaimer and sintered through a belt conveyor. The reclaimer carrying the coke plant and the blast furnace, such as the discharge of the pile pile is shown in FIG.

That is, as shown in Figure 1, the reclaimer 100 is equipped with a running portion 102 to move along the rail installed in the yard 110 while moving the pile pile 120 accumulated in the yard (110). Using the bucket 130 of the crammer 100 is disbursed, and the file is transferred to the belt conveyor 150 installed in the boom 140 of the recramer 100 to be linked to the ground belt conveyor.

By the way, as shown in Figure 1, the pile 120 piled on the yard 110 is about 15-18m in height, so when the pile pile 120 is dispensed through the bucket 130 in several stages In other words, the upper and lower parts are alternately dispensing, wherein the boom 140 and the belt conveyor 150 installed thereon are inclined.

On the other hand, as shown in Figure 2, the belt conveyor 150 is installed in the boom 140, the belt 152 is maintained in close contact with the drive pulley 154 in close contact with the rotary pulley, so The weight 160 is necessary to keep the tension of the belt 152 constant at all times.

That is, as shown in Figure 2, the belt conveyor 150 installed in the boom 140 is transferred to the endless track by the drive pulley 154 and a plurality of feed rollers (156a) and return rollers (156b) piled pile The belt 152 is transferred to the belt 152 by the band pulley 158a and the weight pulley 158b installed at the boom 140 and is connected to the weight pulley 158b at the return line of the belt 152. The tension is adjusted while being pulled down by the weight 160.

Meanwhile, FIGS. 3 and 4 illustrate weights 160 of the conventional belt conveyors, and guide bars 164 are installed on both sides of the case 162 fixed in the vertical direction to the boom 140. The guide bar 164 is inserted and supported by the guide plate 166 of the support bar 165 fixed downward to the bearing portion of the weight pulley 158b, and the weight 160 is provided below the support bar 165. The connection is fixed.

However, as shown in FIG. 3A, since the case 162 is fixed to the lower portion of the frame of the boom 140, the conventional weight 160 has a pile pile 120 as shown in FIG. 3B. When the boom 140 is inclined during the operation of the bucket 130 for dispensing), the weight pulley 158b and the weight 160 act vertically in the load direction but are actually inclined. Since the weight 160 does not pull the belt 152 in the vertical direction, the belt 152 may not maintain a predetermined tension or more, and the belt 152 may slip on various pulleys and rolls. And at the same time, the weight case 162 fixed to the frame of the boom 140 is also a problem that will receive a direct comfortable load.

In addition, the weight 160 and the weight pulley 158b is connected to the guide bar 164 on both sides of the center of the case 162 and the guide plate 166 of the support bar 165 supported thereon is the boom 140. When the inclination of the weight 160 is not smoothly maintained without moving up and down, the weight 160 is unbalanced or severely causes the meandering or breaking of the belt 152, and the weight of the weight 160 There were several problems, such as causing a lower fall.

The present invention has been made in order to improve the various problems as described above, the object is, the boom of the reclaimer boom discharging equipment moving to the upper and lower portions of the pile pile due to the height difference of the pile pile, the slope of the boom according to the discharge Even when the belt is changed, the belt can be pulled in the vertical direction to keep the belt constant, and also to prevent the belt from slipping and twisting due to irregular tension, thereby preventing equipment damage such as meandering and breaking of the belt. It is to provide a boom belt conveyor weight device of a reclaimer which is prevented from biasing.

As shown in FIG. 5 and FIG. 6, the related reclaimer boom 10 of the present invention is provided with a belt conveyor 20 for transferring the discharged pile pile to the ground conveyor, the inventors on the return line The weight device 1 is installed.

And, as shown in Figure 5, the weight device 1 of the present invention is largely a rectangular case 40 and the support roll 28 which is a return bar of the moving bar 50 and the belt conveyor 20 to move along it. ) And a weight 60 connected to the lower side of the weight pulley 24 passing through the band pulley 26, and each of the components 40, 50, 60 is as follows. .

First, FIG. 6 illustrates in detail the rectangular case 40 of the apparatus 1 of the present invention. The rectangular case 40 of the present invention has a pin 42 connected to an upper portion of the boom 10. When the boom 10 is inclined, it is always configured to be held in the vertical direction.

That is, as shown in FIG. 6, the support block 44 into which the pin 42 is inserted and supported is integrally formed at the upper end of the case 40 so that the pin 42 is formed on the frame 12 of the boom 10. ), The case 40 is a U-shaped panel in which the guide groove 40a is formed to guide the first bearing block 54 to the inside is formed in a quadrangular shape, of course, the square case 40 is The bottom portion must be separated and assembled for the inner insertion of the guide roll 52 described below.

And, although not shown in the drawings, the reinforcing ring is installed in the frame 12 portion of the boom 10 to which the pin 42 inserted through the support block 44 of the rectangular case 40 is fastened. It would be desirable for 42 to be fastened.

As a result, since the rectangular case 40 in the apparatus 1 of the present invention flows in the shaft 12 of the pin 42 on the frame 12 of the boom 10, the case 40 is caused by the height difference of the pile pile. Even when the boom 10 has an inclination when discharging the pile, the rectangular case 40 always maintains the vertical direction to integrally move the weight pulley 24 described below and the moving direction of the weight 60 connected thereto. It serves to keep the belt tension constant by making it vertical.

Next, Figure 6 shows the moving bar 50, the moving bar 50 of the present invention is made of a pair of upper and lower sides, the guide roll to move up and down inside the rectangular case 40 52 is provided at both ends thereof, and the first bearing block 54 mounted at the end of the shaft portion 24a of the weight pulley 24 on which the belt 22 is wound is fixed therebetween.

That is, the movement bar 50 supports the shaft portion 24a to move the weight pulley 24 so that the weight pulley 24 can be stably moved up and down along the case 40.

On the other hand, the upper end of the support bar 64 is fixed to the lower side of the second bearing block 62 mounted to the pulley shaft portion 24a inside the first bearing block 54 of the weight pulley 24, Weight 60 is fixed to the lower end of the support bar (64).

Therefore, while the belt conveyor belt 22 of the boom 10 is transported through the weight pulley 24, constant tension is always maintained by the load of the weight 60. The weight device 1 of the present invention is the weight 60 ) Is connected to the shaft portion 24a of the weight pulley 24, and the shaft portion 24a is a moving bar 50, and the rectangular case in which the guide roll 52 is always vertical even when the boom 10 is inclined ( Since the weight pulley 24 guides the vertical movement of the weight pulley 24 while moving along the load, the weight of the weight 60 is not applied to the guide roll 52 and the square case 40, so that the guide roll of the movement bar 50 ( 52) This vertical movement is a configuration that is smooth.

Referring to the operation of the present invention made in the above configuration in detail as follows.

As shown in Fig. 5 and 6, when discharging the pile piles loaded in the yard, such as coal, which is a raw material used in the steel mill, with a reclaimer, the pile piles discharged into the bucket is a belt conveyor installed in the boom 10 It is linked to the ground conveyor through 20, as shown in Figure 6, when discharging such a pile pile, the boom 10 is inclined for the pile pile operation of the bucket according to the height of the pile pile.

At this time, the rectangular case 40 of the weight device 1 installed on the frame 12 of the boom 10 always has a ground on the pin 42 fastened to the boom frame 12 regardless of the inclination of the boom. Position it vertically.

Therefore, the guide roll 52 inserted into the guide groove 40a of the rectangular case 40 is horizontally fixed to the upper and lower sides of the first bearing block 54 installed on the shaft portion 24a of the weight pulley 24. Since it is installed in the movement bar 50, the weight pulley 24 always moves constantly along the rectangular case 40 when the weight 60 moves up and down according to the belt tension state of the belt conveyor 20. Do it.

Since the weight 60 is fixedly connected to the shaft portion 24a of the weight pulley 24 as the support bar 64 through the second bearing block 62, the weight 60 is attached to the square case 40. Since the load of 60 is not directly transmitted and there is no deformation of the case 40 and the rectangular case 40 is always kept vertical, the weight 60 is always in the vertical direction along the centerline of the weight pulley 24. Since only the load is applied to the belt, the phenomenon of slipping of the belt caused by not transmitting the weight of the weight to the belt according to the inclination of the conventional boom is completely prevented.

In addition, since the vertical movement of the weight 60 is smooth without the indirection between the weight 60 and the rectangular case 40, the tension of the belt is always kept constant.

Accordingly, according to the weight device 1 of the present invention, the weight 60 for adjusting the tension of the belt when the boom 10 of the reclaimer is inclined when the pile pile is discharging is applied to the belt 22 while applying the load in the vertical direction. The case 40 of the weight pulley 24 to which the weight 60 is connected is smoothly moved, thereby preventing problems such as discontinuation due to slip of the belt.

As described above, according to the inventors of the boom belt conveyor weight device of the unrestricted deflection, even when the boom is inclined due to the height difference of the pile pile, the weight for adjusting the belt tension of the belt conveyor is always perpendicular to the ground. By pulling the weight pulley to support it, it provides an excellent effect of preventing the belt slip phenomenon, meandering and belt surface damage and other equipment accidents caused by the irregular tensioning of the weight.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to know that those who have knowledge of this can easily know.
