Description

An apparatus which removes the rain water in the upperside of belt conveyor}

The present invention relates to a rainwater removal device of the belt conveyor, and more particularly, to a rainwater removal device to effectively remove rainwater accumulated on the belt conveyor through a relatively simple configuration rather than a complicated device.

Belt conveyors are widely used in various industrial sectors as transportation equipment used to transport materials such as raw materials quickly and efficiently. In particular, it is more useful in large-scale workplaces such as steel mills. In this case, a belt conveyor is also installed in the open air to transport raw materials stored in the open air.

However, when the production work is paused and resumed due to rain or heavy snow, rainwater accumulates on the upper part of the belt conveyor, and when it is operated as it is, some flows to the lower part and the remaining part is mixed with the raw material to process There is a problem that the operation rate is lowered due to delayed operation and production is reduced due to the operation delay or leaked to the outside to cause raw material waste and environmental pollution.

Therefore, to solve this problem, a rainwater removal device is installed and used on a belt conveyor. In the conventional technology, a sensor is installed in the front and rainwater is sensed through this to operate an actuator such as a motor to lower the cleaner, and to remove rainwater. have. However, the conventional technology as described above is difficult to maintain and repair because the configuration is too complicated.

Hereinafter, the operation of the rainwater removing apparatus according to the prior art will be described with reference to FIG.

As shown in the figure, when rainwater collects on the belt, it detects this through the detection sensor 1 and operates the motor 2 through a separate control circuit. At this time, the detection sensor (1) detects a high amount of water in addition to the presence or absence of rain water to adjust the operation degree of the motor (2) through a control circuit. Due to the operation of the motor 2, the connected chain 3 is rotated, which causes the wire rope 4 to move and the press roller 5 and the rubber cleaner 6 to descend to the upper portion of the belt. do. The press roller 5 and the cleaner 6 are thereby brought into contact with the belt, so that rainwater or foreign matter on the belt is removed.

As described above, the conventional technology is composed of various complicated configurations, which requires a lot of cost during installation, and the detection sensor 1 cannot be installed in the open air due to the characteristics of the belt conveyor, which causes failure due to rainwater. high portential. In addition, the prior art uses the friction cleaner (4), so long-term use will need to be replaced due to wear. Therefore, the prior art has a problem that requires a large cost in terms of installation, maintenance and repair.

In order to solve the problems of the prior art as described above, an object of the present invention is to provide a device capable of removing rainwater accumulated in the upper part when resuming work stopped due to rain on a belt conveyor through a simple configuration.

In the present invention, in order to solve the above technical problem, in the belt conveyor including the frame 10, the carrier roller 11, and the belt 12, the belt 12 is located on the lower surface of the central part of the belt 12 due to rotation. A convex roller 20 for raising 12; A bar 21 that rotates the convex roller 20 and is fixed vertically to the frame 10; A roller bracket 22 mounted to the bar 21 to fix the convex roller 20 and hinged to the convex roller 20; An arm (23) mounted on the bar (21) extending to the ground at an angle perpendicular to the ground when the convex roller (20) descends; A stop bar 24 extending from one end of the bar 21 to the frame 10 to limit the rotation of the bar 21; A frame bracket 25 mounted on the frame 10 and a bearing 26 mounted in the frame bracket 25 to fix the bar 21 to the frame 10; An actuator 30 for rotating the bar 21; A wire 31 connecting one end of the actuator 30 and a lower end of the arm 23 to transfer the operation of the actuator 30 to the arm 23; In order to support the actuator 30 to the frame 10, it is characterized in that it is composed of a plate 32 installed on the frame 10.

Hereinafter, with reference to the accompanying drawings will be described in more detail the configuration of an embodiment according to the spirit of the present invention.

As shown in Fig. 3, the convex roller 20 is provided on the bar 21 by the roller bracket 22 described above on the lower surface of the central portion of the belt 12. The roller bracket 22 has one end attached to the bar 21 and the other end is hinged to both ends of the convex roller 20 so that the convex roller 20 can rotate. In addition, the roller bracket 22 is provided to have a constant angle, preferably 45 degrees, with respect to the axis perpendicular to the ground when the convex roller 20 is in the lowered position. The bar 21 is equipped with an arm 23 extending perpendicular to the ground when the convex roller 20 is in the lowered position. It is preferable to have a hole for connecting the wire 31 to the ground end of the arm 23, and it is also possible to attach the eye bolt to the wire 31 as shown on both sides of the ground end. Do.

In order to prevent the bar 21 from rotating too much, one end of the bar 21 is bent at a right angle, one end is mounted to the bar 21 and the other end is mounted with a stop bar 24 mounted on the frame 10. do. The stop bar 24 does not necessarily have to be at right angles as shown, but is sufficient if it extends from one end of the bar 21 to the frame 10. The frame 10 is installed on the frame 10 to vertically support the bar 21, and the bar 21 is smoothly rotated within the frame bracket 25 inside the frame bracket 25. The bearing 26 is installed so that it can be.

The block roller 20, the bar 21, the roller bracket 22, the arm 23, the stop bar 24, the frame bracket 25, the bearing 26, and the like described above are as shown in FIG. 3. Likewise, a plurality of frames may be mounted on the frame 10.

On the other hand, the frame 10 is mounted with a plate 32 for supporting the actuator 30, the actuator 30 is mounted on the plate 32 and one end of the actuator 30 through the wire 31 The holes 23 or the eye bolts of the arms 23 or the plurality of arms 23 are connected. The actuator 30 may use a hydraulic or pneumatic cylinder or a motor. It is also possible to install the guide roller on the plate 32 as shown.

Hereinafter, the operation of the present invention will be described with reference to FIG. 4.

In the case of resuming the work stopped by rain or heavy snow, if the rain water is accumulated on the belt of the belt conveyor, the operator checks this and operates the actuator 30. As shown in FIG. The 31 is pulled so that the bar 21 rotates, and the convex roller 20 rises. As a result, the upper portion of the belt 12 is lifted, and the rainwater flows down the slope of the belt by gravity.

Through the configuration of the present invention as described above, it is possible to remove rainwater accumulated on the upper part of the belt conveyor through a simple mechanical configuration without the need for electronic equipment such as sensors that are difficult to maintain and repair, thereby reducing costs and maintaining and repairing. It is also easy to prevent rainwater and raw materials from being mixed into the process, which can reduce costs and prevent environmental pollution.
