Description

Apparatus for fixing the roller stand}

The present invention relates to an apparatus for fixing a roller stand for supporting a roller installed in the lower portion of the belt conveyor, and more particularly, the roller drum damage due to the bearing portion of the roller located in the lower part of the chute and the friction of the roller drum The present invention relates to an apparatus for fixing a roller stand so that the roller stand can be easily separated from the belt conveyor under the chute so that it can be easily replaced.

In general, a belt conveyor for transporting ores and the like is supported by a roller, and the roller is supported by a stand fixed upright on the frame. If the roller is used for a long time, the bearing part of the roller is damaged and the roller drum is damaged by friction with the belt, and this damaged part must be replaced in a timely manner. In order to perform the replacement of such a damaged part, the belt must be lifted, but there is a problem that is not easy due to the tension of the belt.

In particular, as shown in FIG. 1, in order to replace the damaged part of the roller 2 supported by the stand 1 fixed on the base 6 below the chute 3, the chute 3 lower part. The belt (5) which is in close contact with the skirt (4) installed on the side should be lifted.

However, in the process of lifting the belt 5, there is no proper air hole, so when two or more people lift the belt 5 by using a lever, the other worker exchanges the roller. At the time of replacing the roller 2 installed under the chute 3, the stand 3 of the roller 2 fixed to the frame cannot be lifted because the chute 3 is located above the belt 5. The damaged bolt (2) could be replaced only by disassembling the fixing bolt, but since this work was performed in a narrow space and a height area, there was a high risk of safety accidents caused by falling and falling workers.

The present invention has been made in order to solve the conventional problems as described above, when replacing the roller damaged area supported by the stand located in the lower part of the chute without lifting the belt or loosening the fixing bolt It is an object of the present invention to provide a fixing device for fixing a roller stand rotatably mounted on a base to facilitate exchange.

In order to achieve the above object, according to the present invention, a fixing device for fixing a roller stand for rotatably supporting a roller for supporting the belt is located on the bottom of the chute and the base is installed on the frame, both ends of the base A pair of brackets fixed upright and rotatably installed on the base between the brackets and the roller stand installed on top of the bracket, and an insertion hole is formed at one side of the roller stand. And a through hole corresponding to the insertion hole is formed in the bracket, and further comprising a pin detachably inserted into the through hole and the insertion hole so as to maintain the roller stand upright with the bracket. It features.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

First, referring to FIG. 3, the roller stand fixing device according to the present invention includes a base 60 that serves as a fixing stand and a pedestal. Brackets 50 are attached to both ends of the base 60, and holes 51 are formed below the brackets 50. The first holder 52 is formed on one side of the bracket 50.

In addition, one side of the bracket 50 is elastically supported by a spring 42 and a detachable pin 40 is attached to the first holder 52. The pin 40 is positioned at the rear end of the insertion portion 41 and the insertion portion 41 inserted into the first holder 52 so that the insertion portion 41 remains inserted in the first holder 52. An elastic support 43 is elastically supported by the elastic body 42 and a mounting portion 44 connected to the elastic support 43 to be mounted to the bracket 50.

The pipe 20 is rotatably mounted on the base 60 between the brackets 50 and the stand 10 is attached on the pipe 20. The second holder 30 corresponding to the first holder 52 is attached to one side of the stand 10. The fixing device according to the invention has an axial rod 70 inserted into the hole 51 to penetrate the pipe 20.

Therefore, as shown in FIG. 2, the pin 40 is connected to the first holder 52 in a state where the shaft rod 70 passes through the pipe 60 through the hole 51 in the lower portion of the bracket 50. By inserting into the second holder 30, the roller stand 10 is maintained in an upright position similar to the bracket 50.

At this time, by pulling the pin 40 to the outside to separate the insertion portion 41 of the pin 40 from the first holder 52 and the second holder 30, as shown in Figure 4, the stand 10 Rotate the pipe 20 or the shaft 70 as the rotation axis, as a result, the roller 2 is spaced apart from the belt (5). Thus, the roller 2 is in a state where it can be easily dismantled and fastened.

Therefore, according to the present invention, the operator can easily change the roller stand by rotating the roller stand without lifting the belt using the lever when replacing the damaged part of the roller, so that the roller replacement time can be shortened and the roller damaged part can be easily replaced. Therefore, there is an effect that can exclude the risk of safety accidents.

The foregoing is merely illustrative of the preferred embodiments of the present invention and those skilled in the art to which the present invention pertains may make modifications and changes to the present invention without departing from the spirit and gist of the invention as set forth in the appended claims. It should be recognized.
