Description

Cleaner device of belt conveyor with protection device

The present invention effectively cleans a cake of a package attached to the bottom of the head pulley in the belt system used in the steel industry and returns to the surface of the returning belt. The present invention relates to a cleaner device for a belt conveyor provided with a protection device having a function of controlling dropout as a detection device having a load cell detection and adjustment function.

As shown in FIG. 1, the cleaner device of the conventional belt conveyor is integrally set with the ceramic tip 25 bolted to the support member made of steel, and the rubber cushion 26 fixed to the upper portion of the base 28. The housing 30 was inserted at both ends of the shaft 27, and then the installation angle was arbitrarily determined by the operator, and the fixing bolt 29 was installed to remove the cake attached to the return belt 24 of the head pulley 23.

However, in the conventional cleaner apparatus of this type, there is a deviation in the pressing force by the cleaner tip in the belt width direction by installing the cleaner arbitrarily without using the same standardized method by the operator. This caused scratches in the longitudinal direction on the surface of the belt, causing premature damage to the belt.

In addition, due to the continuous interference between the belt damaged portion and the over-compression cleaner tip, the tip is broken and dropped, thereby causing a cleaning blank point.

In addition, since there is no means for detecting the belt being damaged or the tip is dropped due to the interference between the over-compression cleaner tip and the endless portion of the belt and the portion of the partial damage ratio, the belt is short in time due to the characteristics of the belt conveyor rotating at high speed. It is damaged, the cost for maintaining it is excessive, and the maintenance work takes a long time, a problem such as delayed transportation work is occurring.

The present invention has been made to solve the above-described problems of the prior art, it is possible to adjust the left and right pressing force of the tip by the load cell method, it is possible to detect that the belt damage and the tip interfering with each other, the see-so-type cleaner It is an object of the present invention to provide a belt conveyor cleaner device having an automated cleaner protection device capable of cushioning the impact of the belt.

In the present invention to achieve the above object, in the cleaner device for removing the cake attached to the upper surface of the belt having a cleaner tip and a cushion, the monitoring device provided at both ends of the cleaner shaft is provided in both ends of the lower surface of the cleaner base An upper compression spring case of; A lower compression spring case installed on both sides of the upper surface of the sensing device base so as to face the upper case, and a compression force absorbing compression spring built in the upper and lower cases to operate in a seesaw manner; An upper bracket installed at the center of the cleaner base and a lower bracket installed at the center of the upper surface of the base; A sensing member installed in the upper rear case; Provided is a cleaner device for a belt conveyor having a protective device comprising a load cell installed in a lower rear case and a control means electrically connected to the load cell and configured to stop the belt conveyor drive motor by a sensing action of the load cell.

Hereinafter, with reference to the accompanying drawings showing a preferred embodiment, the cleaner device of the belt conveyor with a protection device of the present invention will be described in detail.

In the cleaner mounting of the belt conveyor provided with the protection device of the present invention, the center of the hole and the center of the cleaner shaft 4 are defined by the bracket 3 having the fastening hole 2 formed at the bottom of the cleaner base 1. Arrange so as to coincide with each other and install the welded portion in the form in which the rounded portion of the bracket 3 faces downward.

Two upper and lower cases 6a and 6b for storing the compression spring 5 are welded and spaced apart at equal intervals from the front and rear of the hole of the bracket 3, and one cylindrical shape is provided inside the case 6b provided at the rear. The load cell detecting member 7 is fixedly installed downward.

In addition, two lower cases 8a and 8b are welded and installed in a portion opposite the upper cases 6a and 6b of the sensing device base 9 so as to accommodate a portion of the upper end of the lower cases 8a and 8b inside the upper case. Then, the lower bracket 10 is installed to face the upper bracket 3 in the center of the base 9 of the sensing device. Here, the holes 2 of the upper bracket 3 and the holes 2 of the lower bracket 10 coincide with the hinges 11 after they coincide with each other.

Inside the lower case 8b installed at the rear, one load cell 12 is installed in a built-in form, and a cable 13 is connected to the load cell 12 to draw out holes 14 provided in the base 9. 4), connected to the converter 15, and then connected to electrical components such as the indicator 16, alarm 17, MCC (18), MCC contact (19) belt conveyor The control means are configured by being electrically configured to connect to the drive motor 20.

And, the sensing device is installed in each of the two ends of the cleaner shaft 4 in an independent configuration, the configuration is the same.

Hereinafter, the operation of the cleaner device of the belt conveyor provided with the protection device of the present invention of the above configuration.

Damage 22 when the damage 22 located on the carrier belt 21 side passes between the cleaner tip 25 and the pulley 23 just before being converted to the return belt 24 by the rotary pulley 23. ) Has a considerable thickness, which imparts a significant impact on the tip 25, a portion of which is absorbed by the cushion 26, but a significant residual impact is again intended to rotate the cleaner shaft 4 towards the advancing direction of the belt 24. Act by force

This impact force is absorbed by the shock absorbing device constructed in the method of the device of the present invention, and at the same time, the sensing member 7 embedded in the rear upper case 6b acts as a force for hitting the load cell 12 so that the load cell ( A sensing action occurs at 12) and the sensing action is transmitted to the electrical element through the cable 13 and applied to the motor 20 to stop the belt 21 to detect damage to the belt, as well as tipping. It works to prevent the fall of 25.

And, when initially installing the cleaner, the loading force of the sensing device installed on the left and right in the width direction of the belt is adjusted to the same size while observing the indicator 16 so that the belt 21 and the cleaner tip 25 have the same wear degree. In this way, the cleaning action is more effectively performed at the front surface of the belt 21 in the width direction.

Therefore, according to the cleaner device of the belt conveyor provided with the protection device of this invention of the said structure, when installing a cleaner initially, the pressure of a tip can be adjusted and set so that the same pressure may act on the line part of the belt width direction, and thereby, The belt and tip wear speed is the same to reduce the maintenance cost by reducing the number of parts required for uneven wear, and the cleaning pressure can be eliminated because the tip pressure in the front width direction of the belt is the same, eliminating pollution.

In addition, the belt can be sensed by the detection device that the belt of the endless portion of the belt and the partial joint maintenance point interfere with the tip and the damage is increased by over-compression, thereby extending the life of the belt, and the tip which the conventional cushion cannot absorb An excessive impact force applied is absorbed by the spring-loaded spring buffer device, thereby obtaining an effect of preventing the dropping due to the breakage of the tip.

In addition, it is a useful design to obtain various effects in the industry, such as preventing the expanded reproduction of more than the facility because it can detect the abnormality of the equipment early and stop the belt conveyor by the automated design device.
