The present invention is to automatically detect the unbalance occurrence of the driving part of both sides of the blending reclaimer emitting the blending light, and to correct it, thereby maintaining the running balance of both sides to prevent equipment accidents. It relates to a control device.

In general, the mixed light, which becomes the raw material light of the sintering process, forms the pile of each blend in the blending light stacking yard by deliberate stacking, and transfers the blending light to the sintering storage bin for use as fuel. One of the facilities for discharging and transporting the blending light is a BLENDING RECLAIMER.

For example, as shown in Figure 1, the branding reclaimer (1) is a fixed angle driving motor (3c) and a free angle driving motor on the running rail (2) installed on both sides of the longitudinal blending light loading yard (5) 3d) and traverses with the transverse device 1a installed in the cabin belt body 1b connecting the traveling part and the traveling part, and emits the blending light 5a of the yard 5 by the basket wheel 1e. The belt is transferred to the ground belt 4 via the in-flight chute 1f.

Here, when the basket wheel 1e is rotated and traverses simultaneously, the transverse stops by the detection of the transverse limiting sensor 3i provided at the fixed angle side (A direction) of the loading yard 5, and at the same time traveling in a constant running width. If it stops again, it moves to the free angle side (B direction) together with the traverse operation and repeats the dispensing operation.

The traveling operation of the blending reclaimer 1 in the dispensing operation of the blending light 5a is performed when both of the transverse operations are operated when the transverse limiting sensor 3i is operated from the fixed angle side (A direction) or the free angle side (B direction). The motor will run at the same time to drive the specified section.

At this time, the traveling motors installed on both sides of the fixed angle side (A direction) and the free angle side (B direction) travel the same travel section to maintain 90 ° perpendicular to the longitudinal belt body 1b in the longitudinal direction. It is possible to prevent excessive dispensing and low discharging during the dispensing, and thus the problem of unbalanced driving can be prevented.

However, when the harrow 1g of the traverse device 1a travels at the fixed angle (A direction) during the transverse discharging operation, the harrow (1 g) of the free angle side (B direction) interferes with the pile pile and is fixed at the free angle side driving. Harrow 1g on each side (A direction) interferes with the pile pile and the repulsive force received by the traverse device 1a interferes with the traveling part in the harrow (1g) direction in which both sides of the branding reclaimer 1 interfere. To cause unbalance of the running portion of the branding reclaimer 1 equal to the (C) angle width of (C).

In addition, when discharging from the fixed angle side (A direction) and discharging from the free angle side (B direction), the pile pile interference acting on the harrow 1g and the interference portion of the harrow 1g among the basket wheels 1e on both sides. The phenomenon that the basket is pushed with the running part of the interference emitting part due to the weight difference and the repulsive force between the two sides of the discharge ore and pile interference causes the unbalance of the driving of the branding reclaimer 1.

Such unbalanced driving of the branding reclaimer 1 causes warpage of the running rail 2, and span, which is the distance between the running rails 2, is distorted, so that uneven wear of the running wheel and the running wheel run. A secondary problem of leaving the rail 2 is caused.

In addition, the main body of the branding reclaimer (1) is twisted to increase the excessive load on the main body and the running wheel and the running rail are interlocked with each other to generate a running wheel idling phenomenon that the branding reclaimer (1) cannot travel The discharge amount of the ding light 5a is reduced.

 The present invention was created in order to solve the problems of the prior art as described above, and the branding reclaimer is a device that allows both the traveling portion of the branding reclaimer emitting the blending light and the in-flight belt body to maintain a right angle. Running of the mixed light emitting reclaimer to detect the unbalance between the traveling parts on both sides and the onboard belt body at an early stage and properly correct it to maintain the running balance by maintaining the right angle between the traveling parts on both sides of the equipment and the onboard belt body. The purpose is to provide a balance automatic control device.

The above object of the present invention is a symmetrical rail guide portion spaced apart from one side of the traveling main body beam and installed to be movable without flow along the running rail; A detection bar rotatably fixed to a center of an upper surface of the symmetrical rail induction part and disposed close to one side of the traveling main body beam; A steady state detection plate fixed to one end of the detection bar and high driving and low driving limit plates; An unbalance detection device unit having one end fixed to one side of the traveling main body beam and a portion of the detection bar rotatably fixed to the other end surface; An unbalance sensor device unit fixed to one end surface of the unbalance detection device unit and comprising a plurality of sensors for detecting positions of the steady state detection plate and the high travel and low travel restriction plates to detect unbalance of the traveling main body beam; One end is fixed to the unbalance detection unit and the other end is fixed to an elastic fixed shaft protruding on one end of the detection bar, characterized in that it comprises a pair of symmetrical elastic body to elastically operate to always center the detection bar. It is achieved by providing a running balance automatic control device for a reclaimer for mixing light.

In FIG. 2, an elastic body 10 for maintaining the horizontality of the detection bar 8 and the traveling rail 2 is formed by connecting the return elastic pin 7a and the elastic body fixing shaft 8d of the detection bar 8. .

In FIG. 4, the detection bar 8 has a rectangular bar shape, and a hole is machined in the middle portion thereof to process the main shaft hole 8e for fixing the detection bar shaft 7d, and the symmetrical rail on one side in the longitudinal direction. A symmetrical rail induction hole 8f, which is a fixing hole for fixing the induction part fixing shaft 9c of the induction part 9, is machined, and one elastic body fixing shaft 8d is attached from the opposite side in the longitudinal direction to the inside, and both ends of the end part are attached.

The operating relationship of the present invention made of such a configuration is as follows.

First, a phenomenon in which driving unbalance occurs while the traveling parts of the branding reclaimer 1 and the belt belt main body 1b that do not maintain the right angles and emits the branding light is fixed as shown in FIG. There are two types of driving unbalance which occurs when driving in 'A' direction is more than 'B' direction and driving unbalance caused by driving in 'A' direction than 'B' direction.

The driving of the branding reclaimer 1 is free of the fixed angle driving motor 3c and the free running according to the fixed traveling width specified in the cab when the traversing device 1a operates the traverse limiting sensor 3i installed at the fixed angle or the free angle. Each driving motor 3d is operated at the same time and controlled by the traveling synchro apparatus 11 to travel.

That is, as shown in (b) of FIG. 1, when the 'A' direction and the 'B' direction are driven in the same manner, as shown in FIG. It operates to operate normal driving according to driving selection without controlling driving motor.                     

However, as shown in (c) of FIG. 1, when a high driving phenomenon occurs in the 'A' direction in which the 'A' direction travels more than the 'B' direction, the driving unbalance occurs out of the normal driving detection action.

The operation of the present invention during the high driving in the 'A' direction generated as described above acts as shown in (d) and (e) of FIG. 5.

That is, when acting as shown in (d) of FIG. 5, the traveling main body beam 3 is twisted counterclockwise, and the unbalance detection unit 7 assembled to the first wheel body 3a on the fixed angle side is counterclockwise. The rotation of the detection bar 8 which is assembled with the detection bar shaft 7d in the detection bar fixing hole 7c of the unbalance detection unit 7 is rotated by rotating away from the right direction of the traveling rail 2.

Rotation of the detection bar 8 is performed by the symmetrical rail induction part 9, which is assembled with the detection bar 8, moves along the running rail 2 to coincide with the center of the running rail 2. When the detection bar 8 rotates clockwise around the guide part fixed shaft 9c, the high travel limiting plate 8b installed in the opposite direction of the detection bar 8 rotates to drive the high balance of the unbalance sensor device 6. The sensor 6b is detected.

In response to the detection of the high traveling sensor 6b, when the transverse limiting device 1a operates at the fixed angle or the free angle, the fixed angle driving motor 3c at the fixed angle is stopped. The free-angle driving motor 3d travels and travels to the designated traveling width, so that the transverse discharging operation is continuously performed.

When the detection bar 8 is rotated as shown in FIG. 5C to detect the normal symmetry sensor 6a in such a single driving, the detection bar 8 is switched to the normal driving control. Otherwise, the high driving sensor 6b continues to detect it. When acting, the traverse device 1a detects the traverse limiting sensor 3i on the opposite side and repeats the driving of only the free angle traveling motor 3d so that the detection bar 8 detects the normal symmetric sensor 6a. The control is performed continuously until it is made.

Even in this operation, the detection bar 8 does not detect the normal symmetrical sensor 6a and the traveling part is warped, so that the high driving limit plate 8b of the detection bar 8 is a high driving limit sensor as shown in FIG. Detecting 6d causes driving unbalance problems that cause the equipment to stop.

If the driving unbalance trouble occurs, the person in charge of the facility reverses the high angle driving motor 3c by the site control panel 12 alone, and the detection bar 8 detects the normal symmetric sensor 6a as shown in FIG. To stop.

On the contrary, when acting as (b) and (a), the driving body beam 3 is twisted clockwise due to the phenomenon in which the 'B' direction is highly driven, and is assembled to the first wheel body 3a on the fixed angle side. If the unbalance detection unit 7 rotates clockwise to move away from the left side of the travel rail 2 and is rotated, it is assembled to the detection bar shaft 7d in the detection bar fixing hole 7c of the unbalance detection unit 7. Rotate the detected detection bar 8.

Rotation of the detection bar 8 is performed by the symmetrical rail induction part 9, which is assembled with the detection bar 8, moves along the running rail 2 to coincide with the center of the running rail 2. When the detection bar 8 rotates counterclockwise around the guide part fixed shaft 9c, the high travel limiting plate 8b installed in the opposite direction of the detection bar 8 rotates, and the unbalance sensor device 6 The traveling sensor 6b is detected.

In response to the detection of the high traveling sensor 6b, when the traverse device 1a operates the traverse limit sensor 3i installed at the fixed angle or the free angle, the free angle driving motor 3d on the free angle side is stopped. The fixed-angle driving motor 3c travels and travels to the designated traveling width so that the transverse discharging operation is continuously performed.

When the detection bar 8 is rotated as shown in FIG. 5C to detect the normal symmetry sensor 6a in such one driving, the detection bar 8 is switched to the normal driving control. Otherwise, the low traveling sensor 6c continues to detect. When the traverse device 1a detects the traverse limit sensor 3i on the opposite side, the traversing device 1a repeatedly travels only the fixed angle driving motor 3c so that the detection bar 8 detects the normal symmetric sensor 6a. Until the control action is performed continuously.

Even in this operation, the detection bar 8 does not detect the normal symmetrical sensor 6a and the running part is warped. As shown in FIG. 5A, the low travel limit plate 8c of the detection bar 8 is a low travel limit sensor ( Detecting 6e) causes the driving unbalance trouble to stop the equipment.

If the driving unbalance trouble occurs, the person in charge of the facility reverses the free angle driving motor 3d alone from the field control panel 12 and stops when the detection bar 8 detects the normal symmetric sensor 6a as shown in (C). .

The high driving limit sensor 6d and the low driving limit sensor 6e installed in the device attached to the second wheel body 3b detect only the occurrence of unbalanced driving trouble and are used for the sole control operation in the field control panel.

The above-described operation is automatically controlled repeatedly so that the running balance and the in-vehicle belt body 1b on both sides of the equipment can maintain the running balance by the automatic control action to maintain the right angle.

As described in detail above, according to the present invention, the span of the running rail is distorted due to the warping of the running rail caused by the unbalance of the driving of the branding reclaimer, so that uneven wear of the running wheel and the traveling wheel leave the running rail. The phenomenon can be prevented.

In addition, the main body of the branding reclaimer is twisted, which puts an excessive load on the main body and the driving wheel and the running rail are stuck together to prevent the driving wheel idling that the branding reclaimer cannot travel, thereby reducing the output of the branding light. have.

In addition, it is possible to prevent the occurrence of equipment troubles caused by damage to the driving wheel and the driving part while preventing the body main body from being inadvertently caused by unbalanced driving of the branding reclaimer.
