Description

Fluid coupling removal device for the field {APPARATUS FOR INSTALLING AND UNINSTALLING HYDROLIC COUPLING ON SITE}

The present invention relates to a device for disassembling and assembling a fluid coupling, which is a power transmission device of an automatic operation facility installed in each factory, and more specifically, for a field for disassembling and assembling a fluid coupling device safely and efficiently in the field. It relates to a fluid coupling desorption device.

In general, steel mill steel mills are the first step in the process of producing steel, which is the first step in the process of transporting and loading each raw material, and a series of work processes to select and transport raw materials of the appropriate size for each plant's purpose. Proceeds to. Various driving motors and drive reducer devices are provided for the purpose of automatically driving such a work, and the fluid coupling device is used to safely and effectively transfer power transmitted from the drive motor to the drive reducer device.

In the steelmaking area, a belt conveyor device is used to transport and store various raw materials, and various places and buildings for sorting raw materials of various sizes are installed in a complicated structure, and to automatically transport each raw material to such a place. Many of these are local facility features.

Various types of fluid coupling devices are used according to the characteristic structure and characteristics of the steelmaking area as described above, but the most commonly used fluid coupling devices are shafts of a reducer connected to a motor (not shown). The boss part is made of a steel material that is combined with the) is formed and its outer shape has a structure formed of aluminum, which is a light metal.

The prior art desorption method of such a fluid coupling device is illustrated in FIG. 9, and FIG. 10 is another exemplary embodiment of the fluid coupling desorption method according to the prior art.

As shown in FIG. 9, the fluid coupling 100 is assembled to the drive reducer shaft 110 and is fixed to transmit power of a motor (not shown) to the drive reducer shaft 110. As shown in FIG. 9, when the installation and use of the fluid coupling 100 is required due to an abnormal phenomenon occurring in the reducer requiring replacement or repair of the fluid coupling 100, it is shown in FIG. Assemble the support bolts 122 to the machined screw holes 102 in the shaft 110 and install the gear plugs 125 as shown, and then attach and detach the bolts 127 for the gear bolts 125. Rotation in the locking direction while coinciding with the center of 122 results in the support force of the support bolt 122 and the rotational force of the detachable bolt 127 interacting with each other so that the fluid coupling 100 is disassembled from the reducer shaft 110.

In addition, in the reverse assembly, the through-type auxiliary plate 130 is installed at the rear end of the support bolt 122 assembled to the screw hole 102 of the reducer shaft 110, and the support bolt 122 is locked. As it rotates to, the fluid coupling 100 is assembled by the rotation thrust transmitted to the auxiliary plate 130 in close contact with the side of the boss portion of the fluid coupling 100, but the support bolt 122 is the reducer side Since the assembly length of the screw part is limited, it is necessary to prepare the support bolts 122 and the auxiliary plate 130 having various lengths, and the auxiliary plate 130 prepared according to the characteristics of the assembly position and location of the fluid coupling 100. The fluid coupling 100 is completely assembled by repeatedly replacing the support bolts 122 several times.

However, according to the conventional method according to FIG. 9 as described above, the support bolt 122 is applied with the thrust acting on the screw hole 112 formed in the reduction gear shaft 110 during the detachment operation of the fluid coupling 100. Repeated assembly caused damage to the screw portion, and the body of the fluid coupling 100 made of hard metal is provided with an unbalanced thrust generated in the unstable installation and fixing method of the gear plug 125, the fluid coupling (100) ) There was a significant problem causing body cracks and breakage.

In addition, work methods that depend only on manual work, such as the preparation of support bolts and auxiliary plates of various standards, have caused many problems such as an increase in the number of workers, delays in work time, and the risk of safety accidents in addition to the accumulation of worker fatigue.

Another method as shown in FIG. 10 has been proposed to solve the above problems, and the method of disassembling the fluid coupling 100 according to the related art illustrated in FIG. 10 is a screw hole formed in the reducer shaft 110. Assemble the support bolt 122 to the 112 and install the clamp 140 made to fit the outer body of the fluid coupling 100, and then between the clamp 140 and the support bolt 122 hydraulic jack ( When 150 is installed and operated, the thrust action of the support bolt 122 and the hydraulic jack 150 fixed inside the reducer shaft 110 is transferred to the clamp 140 coupled with the body of the fluid coupling 100 to supply fluid. The coupling 100 is separated from the reducer shaft 110.

On the other hand, during assembly, after disassembling the support bolt 122 installed on the reducer shaft 110, the auxiliary plate 130 is installed at the end of the boss portion 105 in the fluid coupling 100, and the fluid coupling ( 100) Following the installation of the clamp 140 in the body shape, the fluid coupling (operation by repeatedly replacing the auxiliary rod 152 and the hydraulic jack 150 of various lengths between the clamp 140 and the auxiliary plate 130. 100 could be fully assembled into the reducer shaft 110.

As described above, the fluid coupling 100 has been detached from the hydraulic material and the clamp. However, in the above work method, the large clamp and the hydraulic jack 150, as well as auxiliary round rods of various specifications, are prepared and moved appropriately for each work place. The installation required a lot of time and manpower, and according to the size of the work place or the fluid coupling (100) to perform a limited on-site desorption work was not practical problems and work efficiency did not improve so much safety safety accident The risk of developing is still a serious problem.

The present invention is to solve the conventional problems as described above, to prevent the damage of the fastening screw portion of the fixing bolt to prevent the fluid coupling from being released from the reducer shaft and to effectively prevent the body damage of the fluid coupling made of light metal material In addition to providing a safe disassembly and assembly action, the object of the present invention is to provide a field fluid coupling desorption device that can be easily disassembled and assembled by simple transportation and quick installation.
