COPPER STRING REMOVAL APPARATUS OF POWRE TROLLEY BAR IN OVERHEAD TRAVELLING CRAIN}

The present invention provides a overhead crane that can remove the COPPER STRING caused by the wear of the trolley bar due to the contact between the trolley bar and the pantagraph shoe that are powered by the overhead crane. The present invention relates to a device for removing a cupstring of a power supply trolley bar.

In general, when power is supplied to the overhead crane, the trolley bar and the pantagraph shoe are kept in contact with each other, and they are in contact with each other. Therefore, the trolley bar is worn out for a long time and the cupper string is worn down. Is generated and sparks due to contact with the adjacent power source, and in severe cases, the power is cut off, and therefore, a device that can remove the cuff string is urgently needed.

Conventionally, the worker is hanging on the trolley bar (1) installed in a high place to remove the cupper string (2) by using a tool such as sandpaper, and the main power supplied to the trolley bar (1) in order to perform such removal work. In order to cut off and shorten the working time, many accidents were performed simultaneously, so a safety accident occurred.

On the other hand, since the cranes are installed on the same line several times, they are repaired by setting a date so that they can be repaired regularly, and it is impossible to remove the cuff strings (2) except the regular repair dates.

Therefore, if the overhead crane is used for a long time while the cuff strings 2 are generated in the trolly bar 1, the length of the cuff strings 2 becomes long and stretches downward. When the cuff string (2) created in 1) comes into contact with the trolley bar (1) on the power source S, a spark is generated momentarily and the power is interrupted, and the traveling and traversing device in operation is slipped (SLIP). In addition to damage to the equipment, safety accidents occurred.

In particular, in the case of the overhead crane carrying the molten iron and molten steel of the steel mill, there was a problem that the productivity is reduced and the cost of repairing the facility is excessive due to the long-term suspension of operation when an accident occurs.

The present invention was devised to solve the above problems, by removing the cupper string generated from the trolley bar supplying power of the overhead crane to prevent accidents that may occur during the maintenance work of the cupper string It is an object of the present invention to provide a overhead crane power trolley bar cuff string removal device that can prevent equipment accidents and safety accidents caused by collision due to slippage of the overhead crane when sparking occurs due to the contact between the three power sources.

The present invention for achieving the above object is to remove the cuffstring caused by the wear of the trolley bar due to the contact of the trolley bar and the fantagraph shoe powered by the overhead crane, the contact as the trolley bar is moved In order to remove the ring, the fixing plate is coupled to the brush cover is fixed by a plurality of fixing bolts, the brush made by using the gold steel (金 剛 砂) in the same number and position as the trolley bar, and the insulator coupled to the other end of the fixing plate ( 결합 子) and the spring plate is inserted into both sides of the spring fixing plate formed in the center and the spring groove is inserted into the spring plate is inserted, the locking spring door is coupled to prevent the spring plate is separated at the inlet side Arm, the end of the locking arm and the support member A pair of link arms coupled between the ends of the combined support arms, and a plurality of link arms and support arms respectively coupled to each other so as to maintain a constant distance between the locking and support arms, and a guide bar and a first cylinder installed therebetween. The connection plate and the support member is to include a second cylinder installed on both sides of the lower side of the support member to be elevated while being guided by the fixed rod.

Hereinafter, the present invention will be described in detail with reference to FIGS. 3 and 4.

Figure 3 is an exploded perspective view showing a brush portion of the present invention cupper strip removing device, Figure 4 is an exploded perspective view showing a drive unit of the present invention cupstring removal device, the present design brush (10) ) Is fixed to the brush cover 12 using a plurality of fixing bolts 11 and the brush cover 12 is firmly fixed to another fixing bolt 11 in the lower portion of the fixing plate 13 and fixed The insulator 14 is coupled to the other end of the plate 13.

On the other hand, the insulator 14 has a spring plate 15 is coupled to the center of the spring plate 15 is provided with a spring fixing plate 16, the spring 17 is inserted into both sides of the spring fixing plate 16.

The spring plate 15 to which the spring 17 is coupled as described above is inserted into the spring groove 21 formed in the locking arm 20 and the end of the spring plate 15 is formed to penetrate the spring groove 21. Is inserted into the 22 and the spring cover 23 is coupled to the inlet side of the spring groove 21 to prevent the spring plate 15 coupled to the spring 17 is separated.

The link arm 24 is coupled to one side of the locking arm 20, and the other side of the link arm 24 is coupled to the support arm 31 fixed to the support member 30. 30, three support arms 31 are sequentially installed so as to maintain a constant interval (that is, the interval where the trolley bar is installed).

The locking plate 20 and the support arm 31 are coupled to the connecting plate 32 so that the locking arm 20 and the support arm 31 are maintained at regular intervals, and between the connecting plate 32. The guide bar 33 is coupled to the coupling plate 32 coupled to the support arm 31 is provided with a first cylinder 34 and the coupling plate 32 coupled to the locking arm 20 The rod 34a of the cylinder 34 is coupled.

On the other hand, the support member 30 is inserted into the outer side of the fixed rod 35 to be lifted and the rod 41a of the second cylinder 41 installed in the base 40 on both lower sides of the support member 30 It is installed and the first cylinder 34 and the second cylinder 41 is connected to the air compressor 42 and the hose 43 seated on the base 40.

The present invention configured as described above maintains the trolley bar 1 and the brush 10 separated from each other while using the overhead crane, and the cuff strings generated in the trolley bar 1 2) When the control panel (not shown) is operated to operate the air compressor 42 and the valve connected to the first cylinder 34 to remove the air generated in the air compressor 42 is a hose ( 43 is supplied to the first cylinder 34 to operate the first cylinder 34 in the direction of the arrow shown in FIG. 5B.

When the first cylinder 34 is operated, the connecting plate 32, the locking arm 20 and the link arm 24 coupled thereto are operated and fixed to the fixed plate 13 coupled to the locking arm 20. The brush 10 is moved to the upper portion of the trolley bar 1, and the guide bar 33 is to guide the moving direction of the locking arm 20.

When the air supplied to the first cylinder 34 is cut off and the air is supplied to the second cylinder 41, the support member 30 is pulled downward by the operation of the second cylinder 41. As shown in FIG. 6B, the brush 10 descending together with FIG. 6 is in intimate contact with the top surface of the trolley bar 1.

In this state, when the overhead crane is operated, the brush 10 is in close contact with the upper surface of the trolley bar 1 while the overhead crane is operated. Therefore, the cuff strings 2 generated in the trolley bar 1 are brush ( 10) and the vibration generated when the brush 10 moves in contact with the trolley bar 1 is cushioned by a spring 17 inserted into the locking arm 20, thereby smoothly operating. It becomes possible.

As such, when the cuff string 2 is removed, the brush 10 is restored to an initial state by operating in the reverse order of the above-described operation.

As described above, the present invention can remove the cupper string generated from the trolley bar without breaking the power due to the contact of the power supply trolley bar and the fantagraph shoe of the overhead crane, and thus the equipment accident due to the cupper string. It is a very useful design that can improve productivity by preventing operator's safety accident to remove the cuppers and reducing maintenance costs.
