BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a trolley bar removing device and a ceiling crane including the same.

Generally, a crane (not shown) is a mechanical device that moves a heavy and heavy cargo by using a power and carries it horizontally. Depending on the driving method and form, a crane (overhead crane), a gantry crane, Crane (gib crane) and so on.

The ceiling crane 1 shown in FIG. 1 is a crane used for transporting large-sized heavy objects mainly from a large factory or a warehouse, and is installed near a ceiling of a factory or a warehouse. In this regard, Shinan Bulletin 20-0186835 (registered on Apr. 12, 2000) (patent document).

A traveling rail (not shown) may be installed on both side walls of the building to allow the ceiling crane to move. A normal girder (not shown) may be provided to allow the ceiling crane to move along the traveling rail installed along the predetermined traveling route. And a saddle (not shown) and a wheel (not shown) provided to rotate on the saddle.

In order to move the ceiling crane 1 constructed as described above along the traveling rail, a power supply connection device 10 connected to external power supply means for continuously supplying power is provided as shown in FIG.

The ceiling crane 1 includes a pantagraph 30 capable of being supplied with power through a trolley bar 20 or the like which is a power line and is in continuous contact with the trolley bar 20 for this purpose.

The power supply connection device 10 supplies power in the process of keeping the pant shoe 31 of the phantagraph 30 in contact with the trolley bar 20.

The trolley bar 20 is constituted by a base 22 composed of a shoe 21 made of copper and a steel supporting the shoe 21.

For example, the power supply of the ceiling crane is caused by the contact between the trolley bar 30 and the fancy shoe 22, and the friction between the trolley bar 30 and the fancy tile 22 is continuously generated So that abrasion occurs on the fangsuch (22) composed of carbon having a relatively high wear rate.

As the abnormal abrasion of the flat pad 22 continues, the flat pad 22 is constantly worn away, and the contact surface with the trolley bar 30 extends to the side surface other than the top surface of the trolley bar 30.

When the side surface of the trolley bar 30 and the flat tongue 22 are brought into contact with each other, a corner sharpening occurs at the corner of the relatively weak trolley bar 30, And the conductive foreign material generated in this manner is formed into a long band shape, and such a foreign object is collectively referred to as a co-s String.

When such a copper string S is brought into contact with a power source such as another adjacent trolley bar 30 or the like, a short circuit or the like may be caused, thereby causing a spark, Causing safety accidents.

Further, in order to clarify the gist of the present invention, a description of elements and techniques well known in the prior art will be omitted, and the present invention will be described in detail with reference to the accompanying drawings.

It is to be understood, however, that the spirit and scope of the present invention are not limited to the embodiments shown, but may be suggested by those skilled in the art in other forms, additions, or alternatives, .

As shown in FIG. 4A, a foreign matter removing roller 50 according to a preferred embodiment of the present invention includes a shaft 51, an extension portion A (not shown) connected to both ends of the shaft and extending in the radial direction of the shaft, And a cutting means 53 installed on the extension or the shaft for removing foreign matter from the rail by rotation of the shaft.

The shaft 51 is a circular shaft, and the outer circumferential surface thereof is provided so as to rotate in contact with a certain track or rail (not shown). A plurality of guide members 52 are provided at both ends of the shaft 51 to smoothly rotate the shaft 51 without detaching it from a predetermined track or rail.

The guide members 52 extend in the radial direction D of the shaft 51 and the extended portion A can be extended by an appropriate length in consideration of the thickness of a certain track or rail (not shown) But is not limited by the present invention.

Cutting means 53 may be provided on an outer circumferential surface of the extended portion A of the guide member 52 or the shaft 51. The cutting means 53 may be provided with a first wedge 53a and a second wedge 53b as shown in FIG. 4a.

The first wedge 53a and the second wedge 53b are disposed along the outer periphery of the shaft 51 and may be fixed to the guide member 52 and fixed to the shaft 51, It can be appropriately selected and applied by the environment.

The first wedge 53a and the second wedge 53b must extend a predetermined length toward the rails so as to be in contact with the rails (not shown), and the guide member 52 do not have any particular limitation on their shapes and specifications as they can rotate together with them. However, it will be obvious to those skilled in the art that if the end portion that comes into contact with the rail protrudes sharply toward the rail, it will be easier to remove the foreign matter.

However, if the material of the rail (not shown) is vulnerable to scratches or vulnerable to cracks, the shape of the rail (not shown) may be changed as required, as shown in FIG. 4B.

That is, the cutting means 53 may include a plurality of cutting projections 54 arranged along the outer circumferential surface of the shaft 51 in addition to the first wedge 53a and the second wedge 53b. In this case, damage or wear applied to the rail (not shown) can be reduced, and foreign matter can be continuously removed on the rail along with the rotation of the foreign material removing roller 50. [ The material of the cutting projection 53 can be adopted in consideration of such an effect.

The plurality of cutting projections 53 provided along the outer circumferential surface of the shaft 51 may be different from each other in consideration of the characteristics of the rails, the foreign matter, the working environment, etc. However, .

According to a preferred embodiment of the present invention, the cutting projections 54 may be formed in a rectangular shape rather than a wedge shape. However, according to the material of the rail (not shown), the operator can apply various shapes of the cutting projection 54 and the first and second wedges 53a and 53b, such as a circular shape and a polygonal shape, in addition to the rectangular shape.

Meanwhile, as shown in FIG. 4A, if the number and spacing of the first and second wedges 53a and 53b are adjusted, foreign matter can be removed with a predetermined period on a rail (not shown).

That is, the second wedge 53b is disposed so as to have a spacing distance L that is a predetermined distance from the first wedge 53a disposed on one side of the extension A. When the first wedge and the second wedge are arranged so as to have a spacing distance L, the first wedge and the second wedge rotate together with the rotation of the shaft 51, It is possible to press foreign matter attached to the rail at predetermined intervals and press or cut the rail.

Here, since the first wedge and the second wedge are disposed along the outer periphery of the shaft 51, mutual spacing distance L can be varied by a change in diameter of the shaft. That is, as the diameter D of the shaft 51 increases, the time or distance in which the first wedge 53a located at one point on the outer circumferential surface of the shaft 51 touches the rail (not shown) again increases. Therefore, if the distance L between the first wedge 53a and the second wedge 53b is narrowed as the diameter of the shaft 51 increases, the period of removing the foreign matter is increased Can be shortened.

In this way, when the spacing distance L between the first wedge 53a and the second wedge 53b is narrowed, the operator can appropriately increase the number of the first wedge 53a and the second wedge 53b A plurality of cutting means 53 can be disposed on the outer circumferential surface of the shaft 51. It goes without saying that the same can be applied to the rectangular-shaped cutting projection 54 shown in FIG. 4B.

3, the foreign matter removal roller 50 and the main frame 40 and the plurality of side surfaces 40a, 40b, 40c, And a frame (70).

One side of the main frame 40 is connected to a moving body (not shown), and the other side extends toward the trolley bar 20 and is connected to the upper supporting plate 42 through a connecting member 43. At this time, the upper support plate 42 may be additionally installed in the main frame 40, and it may be selectively installed depending on the operator and work environment.

A plurality of side frames (70) are connected to both sides of the upper support plate (42), and the side frames extend downward to a predetermined length toward the trolley bar (20). Both sides of the foreign material removing roller are coupled to the side frame by a coupling member 71 together with a bearing (not shown). This is to prevent the side frame 70 from interfering with the rotation of the foreign material removing roller 50 coupled to the side frame 70.

In addition, the trolley bar 20 may be fixed with a foreign body collection box 60 disposed at the lower end of the foreign material removing roller 50. The foreign body collection box may be provided along the trolley bar 20. In this case, foreign matter removed by the foreign material removing roller 50 moving along the trolley bar 20 may be scattered at any point of the trolley bar 20. [ And is collected and collected into the foreign body collection box 60 without being separated. However, the debris collecting box 60 may be installed only at a point where a large amount of foreign matter is generated as needed, and in this case, the space can be used more efficiently. However, this is not a limitation of the present invention, but can be applied to changes.

On the other hand, on the other hand, the present invention provides, in another aspect, a pantograph 30 for supplying power and a ceiling crane 1 including the trolley bar removal device associated with the pantograph. In this case, the mobile body (not shown) to which the main frame 40 is connected may be a phantagraph 30.

3, one side of the main frame 40 may be connected to one side of the pantograph 30 connected to the ceiling crane 1 through an insulator 41 as an insulator.

The ceiling crane 1 equipped with the trolley barb remover may be constructed in such a manner that the phantagraph 30 contacts with the trolley bar 20 and moves in contact with the trolley bar 30, The string S can be easily removed.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be apparent to those of ordinary skill in the art.
