The present invention relates to a stand apparatus having a bidirectional meandering function of the return belt, and more particularly, a return for preventing and adjusting a knitting phenomenon caused by the return belt meandering of a belt conveyor, which is a facility for transporting raw materials in a steel mill raw material factory. A stand apparatus having a bidirectional meandering function of a belt.

In general, a belt conveyor, which is a facility for transporting raw materials in a conventional steel mill raw material factory, as shown in FIG. To a transport belt (1) for moving on the carrier stand (3a) installed, and to a return belt (2) for transporting on a horizontal return stand (3b) installed on the lower part of the transport belt (1) after discharging the raw materials. It is composed.

In a general belt conveyor installation having the above-described configuration, since the transport belt 1 has a fin shape, only the guide rollers 3a-1 provided on both sides of the carrier stand 3a are used for the transport belt 1. It can easily prevent meandering.

However, the return belt 2 traveling horizontally in the forward or reverse direction in the lower portion of the transport belt 1 described above has a difficulty in preventing meandering of the belt.

That is, as shown in FIG. 2A, when the belt meandering phenomenon occurs when the return belt 2 proceeds in the forward direction F, guide rollers provided on both sides of a certain return roller 3b-1 ( 3b-2) and the return belt (2) meandering in contact with the left side of the return roller (3b-1) inclined in the direction of the belt progression, the right side inclined in the opposite direction to increase the friction coefficient meandering to the left side The return belt 2 is moved to the right to operate the belt 2 normally.

However, as shown in FIG. 2B, when the return belt 2 moves in the reverse direction B instead of the forward direction, the guide roller 3b-2 moves in the direction in which the return belt 2 proceeds. Since the friction coefficient of the meandering side of the belt is continuously increased, the meandering step is promoted so that the meandering stand 3b as described above is applied to a belt conveyor operating in the forward or reverse direction. It can not be used because it can cause fatal damage to the belt.

In order to solve the above problems, the present invention provides a stand apparatus having a bidirectional meander adjustment function of the return belt that can prevent the belt meandering by elastically corresponding to the forward and reverse operation of the return belt. There is this.

As shown in Figure 3 to 7, the present invention, first, the switching base 14 is installed and fixed to the lower predetermined portion of the return belt (2),

A pair of bearing blocks 10a are installed on the switching base 14, and the seesaw base 10 is inserted into and fixed to the bearing block 10a by the base shaft 10a-1. 10) Stands 4a and 4b are mounted on stand bearings 9a and 9b fixed to both sides,

Forward and reverse actuating rolls 4a-1 and 4b-1 are rotatably mounted on the stands 4a and 4b to support the return belt 2 from below.

The guide rolls 4a-3 and 4b-3 are rotatably mounted in the guide roll stand so as to face each other on both sides of the forward and reverse operation rolls 4a-1 and 4b-1.

An operation roll driving part is installed at one end of the switching base 14. First, a lower arm holder 17 is fixedly installed at a lower end thereof, and a flow formed in the lower arm 19 by fixing bolts 20a and 20b. It takes a structure that is coupled to each other in a structure that passes through the groove (19a).

In addition, a pair of supports 16a-1 and 16b-1 are erected on the switching base 14, and guide shafts 16 pass through the supports 16a-1 and 16b-1 and are guided to both ends of the shaft. Guides 16a and 16b are attached and fixed.

The shaft center 16c of the guide shaft 16 is passed through the hole of the upper end of the lower arm 19 after passing through the link shaft 18c, and finally fastened to the fixing nut 18d.

The upper arm Arm 18a is connected to the lower flow groove 19a of the lower arm 19 by the fixing nut 18b while the spring 18 is inserted into the upper arm 18a and 19. And between the guide shaft 16 is organically operated with each other.

The protrusion of the base shaft 10a-1 passes through the hole in the head of the upper arm 18a and the bearing block 10a, and the stopper 10a-2 at the end of the base shaft 10a-1 The upper arm 18a is inserted into a groove formed in the trough so that the upper arm 18a and the seesaw base shaft 10a-1 move simultaneously.

Further, drive roll shafts 8a, 8b on which drive rolls 8a-1, 8b-1 are in close contact with the lower end of the transport belt 1 of the belt conveyor are mounted on the bearing blocks 8a-3, 8b-3. Is fixed to the right end of the driving roll, and the sheaves 11b and 11c are attached, and the power is driven by the sheaves 11a and 11d and the driving belts 13a and 13b attached to the reduction gears 12a and 12b at the lower end. The structure is delivered.

Pushing levers 12a-1 and 12b-1 equipped with the ratchet gears 12a-2 and 12b-2 are mounted inside the opposite sides of the reducers 12a and 12b.

The ends of the pushing levers 12a-1 and 12b-1 have a weight structure and are positioned in line with the guide guides 16a and 16b.

In addition, the induction guides 16a and 16b are formed in a streamlined shape so as to be easily received and transmitted by the rotational force of the pushing levers 12a-1 and 12b-1.

Hereinafter, the operation of the present invention will be described in detail.

8 is a conceptual diagram showing an operating state of the stand apparatus having a bidirectional meandering function of the return belt according to the present invention.

By the structure described above, referring to the contents shown in FIG. 8, as shown in the front view shown in FIG. 6, when the transport belt 1 moves in the forward direction F, the driving roll 8a-1 rotates. Then, the rotational force is transmitted to the reducer 12a through the sheave 11b and the drive belt 13a.

When the rotational force is transmitted to the speed reducer 12a, the pushing lever 12a-1 rotates while maintaining the idle state in which the ratchet gear 12a-2 rotates while the driving force is increased along with the speed reduction. Instead, it is always positioned at the lower end by the weight of the head of the pushing lever 12a-1.

On the other hand, while the opposite pushing lever 12b-1 is rotated at a low speed due to the reverse rotation of the ratchet gear 12b-2, as shown in FIG. 7, the support guide (b) is pushed when the streamlined induction guide 16b is pushed. When the spring 18 moving horizontally and being organically connected in 16a-1 and b-1 is being compressed and under pressure, the compressed spring 18 is unfolded at the moment when the compressed spring 18 is extended. 16b) The whole is moved completely to the other side.

Therefore, the seesaw base 10 is flipped to the opposite side along with the seesaw base shaft 10a-1 based on the moving force, and the reverse operation roll 4b-1 on the right side moves away from the return belt 2 and the forward direction on the left side. The operation roll 4a-1 is in close contact with the return belt 2 to adjust the meandering of the return belt 2 by the movement of the guide roll 4a-3 according to the general principle of the conventional meander prevention stand.

On the other hand, the reverse operation roll (4b-1) of the opposite side does not affect the opposite side at all because the right guide roll (4b-3) is separated from the return belt (2) to perform a normal belt meandering operation.

Further, even when the return belt 2 operates in the reverse direction, the reverse operation roll 4b-1 supports the return belt 2 in the same manner as the above-described forward operation, and the forward operation roll 4a-1. Is moved downward by the seesaw base 10 so as not to contact the return belt 2.

As described above, the present invention prevents expensive belt damage due to the malfunction of the forward motion self-aligning stand used for the reversible belt in the normal forward and reverse directions, induces the normal transportation of raw materials, and contributes to the improvement of productivity after the fact. It can be expected to reduce the repair cost and the fallout treatment cost caused by the fall of the return belt and the equipment damage.
