Therefore, as shown in FIG. 4, the counter roll 30 is raised when the drive cylinder 52 is advanced, and the stand 10 is rotated counterclockwise about the axis of the stand 14 to stand. The broken feed roll 120 'on 10 is separated and separated from the bottom of the belt 110.

Next, FIG. 2 and FIG. 4 show the detection means 70 of the curved pipe feed roll damage detection and roll separation device 1 of the belt conveyor of the present invention. It is connected to the operation panel (C) electrically connected to the drive means 50 and is installed to detect the rotation of the roll when the roll 120 is broken.

That is, as shown in FIG. 2, the sensing means 70 is in close contact with the surface of the belt 110 and rotates when the belt is moved, the rotation sensor 72 and one side of the feed roll 120. Proximity sensor 74 is disposed adjacent to the feed roll shaft to detect the rotating rod (74a) installed in the.

In this case, each of the sensors 72 and 74 is electrically connected to the operation panel C connected to the driving cylinder 54 through the signal box 76, and the proximity sensor 36a installed on the base 12. ) 36b are also configured to be electrically connected to the operation panel (C).

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

As shown in Figure 2 to 4, in the belt conveyor 100 for transporting raw, fuel, etc. in the steel mill is installed on the curved pipe 130 of the belt 110, the transfer roll to enable the transfer of the belt ( 130 ') is immediately detected when the corresponding roll is replaced by a support roll to support the belt curvature to maintain a constant belt support transfer to increase the mobility of the belt conveyor 100, and at the same time separate the broken roll from the progress line of the belt conveyor The transfer roll breakage detection and roll separation device 1 of the belt conveyor of the present invention to prevent the belt damage and fire caused by friction between the break roll and the belt is as follows.

First, as shown in Figures 2 and 3, looking at the operation of detecting the breakage of the conveying roll 120, the conveying roll (120 ') that is broken in the belt conveyor 100 is generated and the conveying roll 120 If the feed is not rotated on the stand 10, that is, the feed roll is broken, the rotary rod 74a provided on one side of the feed roll 120 does not rotate.

Therefore, the rotation sensor 72 is in close contact with the upper surface of the belt 110 to the one side to operate the signal is generated, the signal is generated, the transfer roll 120 is damaged and does not rotate, proximity sensor No signal is generated because the 74 is not activated, and the signal box 76 connected with the sensors 72 and 76 sends a signal to the device operation panel C.

As a result, the driving cylinder 52 of the driving means 50 electrically connected to the apparatus operating panel C is advanced. Although schematically illustrated in the drawing, the hydraulic unit side electronic actuation of the driving cylinder 52 is actually performed. It is connected to the valve to control the operation of the drive cylinder (52).

On the other hand, as shown in Figures 2 and 4, when the movable arm 54 connected to the drive cylinder 52 is advanced by the operation of the cylinder, the corresponding roll 30 is connected to each of the movable arm 54, respectively The roll shaft 32 of the stand is raised along the base guide groove 34, and at the same time the stand 10 is provided with a fixed rod 56a is connected to the first connecting arm 56 connected to the movable arm 54 is integral The furnace pin 14 is pushed forward with its axis.

Therefore, the transfer roll 120 on the stand 10 is simply a broken transfer roll 120 'on the stand 10 in which the roll shaft 122 is seated in the fixing groove 16. When the transfer roll 120 is broken from the belt 110, it is separated from the bottom surface of the belt 110 and prevents continuous friction between the belt and the broken roll 120 ', thereby preventing damage to the belt 110 and the equipment fire due to friction. To prevent it.

Next, as shown in FIGS. 2 and 4, when the drive cylinder 52 is moved forward, the corresponding roll 30 having the shaft portion 32 connected to the second connecting arm 58 has a guide groove () of the base 12. 34, the shaft 32 ascends to support and transport the bottom surface of the belt 110 from which the transfer roll 120 is separated from the stand 10, and eventually the belt transfer roll 120 is broken so that the belt progress line. Even if separated from the new counterpart roll 30 is raised to keep the conveyance of the belt 110 smoothly.

In addition, when the drive cylinder 52 receives the signal of the device operating panel C and moves backward so that the new feed roll 120 is seated on the stand 10, the first and second connections connected to the moving arm 54 connected thereto are performed. As the arms 56 and 58 are integrally retracted, the corresponding roll 30 descends along the base 12 while the new feed roll 120 of the stand 10 supports the conveyance of the belt 110. It returns to the initial state again.

In addition, the operator can easily re-inject the broken roll 120 'separated from the stand 10 to the belt conveyor 100 quickly.

Accordingly, according to the curved portion conveying roll damage detection and roll separation device 1 of the belt conveyor of the present invention, when the conveying roll 120 receives a load from the curved portion 130 of the belt conveyor 100 and its rotation is stopped. In this case, the conveying roll 120 'which is damaged while being quickly detected is separated from the belt 110, and the belt conveyer is supported to support the conveying of the belt as the corresponding roll 30 until the new conveying roll 120 is introduced. While increasing the operation rate of the (100) is to prevent the occurrence of fire due to belt damage and friction.

As described above, according to the present invention, the conveying roll breakage detection and roll separating apparatus of the belt conveyor does not rotate the conveying rolls installed in the belt bends of the belt conveyor during the raw and fuel transportation of the steel mills. By smoothly supporting and transporting the belt as a corresponding roll that senses the state of the transfer roll, the belt conveyor provides an effect of maintaining the operation of the belt conveyor despite the breakage of the transfer roll.

In addition, by automatically separating the broken transfer roll from the belt transfer line, it prevents the surface damage of the belt due to the roll to be broken, and also facilitates the maintenance and maintenance of the broken transfer roll, in particular, between the roll to be broken and the belt. It is to provide an excellent effect of preventing equipment fires due to friction in advance.

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.
