Description

[0001] GUIDE ROLLER ASSEMBLY FOR CONTINUOUS SHIP UNLOADER [0002]

The present invention relates to a guide roller assembly for a continuous unloading machine, and more particularly, to a guide roller assembly for a continuous unloading machine that is easy to replace.

In general, a continuous type unloading unit is a device used to transport bulk cargo (coal, grain, cement, minerals, etc.) transported through a ship, and a continuous cargo handling unit is placed on a ship docked in the harbor.

Particularly, a continuous unloading unit transports bulk cargo using a bucket. A plurality of guide rollers are installed on both sides of the bucket to ensure smooth rotation and to move in a constant direction along the guide rails.

When the continuous unloading machine is used for a long period of time, as shown in Fig. 1, the operation of replacing the guide roller 20 in the continuous unloading machine main body 10 is performed. Conventionally, when replacing the guide roller 20, the support block 30, which rotatably supports the guide roller 20, is detached from the apparatus and replaced. In this case, since the guide roller 20 and the support block 30 are fastened together, their weight is heavy, and a large number of workers have to perform work using a crane. Therefore, there is a problem that a lot of manpower and work time are required for the replacement work of the guide roller 20. [

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings.

2 is an exploded perspective view schematically showing a guide roller assembly for a continuous unloading machine according to an embodiment of the present invention. FIG. 3 is a plan view schematically showing an inner side surface of the guide roller divided in the guide roller assembly for the undercarriage according to the present invention, FIG. 4 is a plan view of the guide roller assembly, Fig. 5 is a cross-sectional view schematically showing a state of being fastened to a main body. 5 is a side view in which divided guide rollers are disposed on both sides of a shaft provided with a support block in the guide roller assembly for a continuous unloading machine.

2 to 5, the continuous guide roller assembly 100 for an undercarrier according to an embodiment of the present invention includes a fastening block 500 fastened to a support portion S formed in a main body of a continuous unloading machine, A guide plate 400 coupled to the shaft 300 by rotation of the shaft 300 and coupled to the support portion S by a shaft 500, And a guide roller 200 disposed to surround the guide plate 400 and rotated together with the shaft 300.

The supporting portion S is provided in the main body of the continuous type unloading machine, and a semicircular groove is formed so that the shaft 300 can be inserted and rotated.

The coupling block 500 is bolted to the support S when the shaft 300 is disposed in a semicircular groove formed in the support S. In this case, the coupling block 500 is formed with a semicircular support groove 510 corresponding to a semicircular groove formed in the support portion S so that the shaft 300 is rotated together with the support portion S .

The guide roller 200 includes a roller body 220 having a central portion 220 smaller in diameter than both end portions 230 and having a flange portion 240 extending outwardly between the center portion 220 and the both end portions 230 A plate support groove 250 formed on the inner side of the roller body 210 and into which the guide plate 400 is inserted and a shaft 250 formed on the inner side of the roller body 210, The shaft insertion groove 260 is formed.

That is, the guide roller 200 is formed therein with a plate support groove 250 in a radial direction in which the guide plate 400 is inserted, and the shaft 300 is inserted into the shaft insertion groove (Not shown).

The roller body 210 may have a cross section in the radial direction of the rotary shaft by the center portion 220, both side ends 230 and the flange portion 240,

The guide plate 400 is disposed in a radial direction of the roller body 210 and has a shape corresponding to a cross-sectional shape of the roller body 210 in the radial direction.

That is, the guide plate 400 is formed as a flat plate having a predetermined thickness and is formed in a shape of 'ㅛ' shape corresponding to a radial cross section of the roller body 210, It is preferable to be formed so as to be disposed on the inner side.

The guide plate 400 protrudes to the outside of the roller body 210 and is supported by the coupling block 500 and the support portion S to restrict axial movement of the shaft 300 A stopper 410 may be provided.

That is, when the guide plate 400 and the shaft 300 are rotated together with the guide roller 200, the guide rollers 200 are mounted on both ends of the guide plate 400 to prevent the guide roller 200 from swinging in the left- (410) may be provided. Therefore, the stopper 410 is supported by the coupling block 500 and the support portion S so that the guide roller 200 can be prevented from moving left and right while being rotated.

Here, the guide roller 200 may be divided into two roller bodies 210 to be fastened to the guide plate 400 and the shaft 300.

That is, as shown in FIG. 5, the roller body 210 may be provided with a first roller body 211 and a second roller body 212. In this case, the shaft 300 to which the guide plate 400 is fastened is positioned between the divided first roller body 211 and the second roller body 212, and the first roller body 211, The roller body 210 may be fastened to the shaft 300 by welding the first roller body 211 and the second roller body 212 after the first roller body 212 and the second roller body 212 are in close contact with each other .

Alternatively, though not shown in the drawings, a through slit may be formed on one side in the radial direction of the roller body so that the guide plate and the shaft are inserted into the guide roller. Here, the through-slit is formed in an insertion groove of the roller body in a direction opposite to a direction in which the plate support groove is formed. In this case, the roller body may be inserted into the shaft through the through-slit, and then the through-slit may be welded to fasten the roller body to the shaft.

As described above, although the present invention has been described with reference to specific embodiments and drawings, it is to be understood that the present invention is not limited thereto and that various changes and modifications may be made without departing from the spirit and scope of the present invention by those skilled in the art. It is to be understood that various changes and modifications may be made without departing from the scope of the appended claims.
