A chain replacement unit for a forging product according to an embodiment of the present invention will be described with reference to the drawings. FIG. 3 is a perspective view illustrating a chain replacement unit for a forging product according to an embodiment of the present invention, and FIG. 4 is a front view of FIG. 2. Referring to FIG.

3 to 4, the chain replacement unit for moving a forged product according to the present embodiment includes a chain replacement unit 100 used to move a heavy-weight forged product among components used in a turbine, (110) having an inner region divided into a plurality of regions and a main beam member (20) stored in the storage unit portion (110) and used for moving a forgings And a main chain (30) engaged with the main chain (30). For reference, the forged product will be described as the rotor 5.

The main beam member 20 according to the present embodiment is used, for example, to perform a movement for a heat treatment operation on the rotor 5 provided in the turbine. More specifically, the rotor 5 is maintained in a weight of tens of tons and is moved to the rotor 5 through a heavy equipment such as a crane (not shown) for heat treatment.

In this process, the operator must mount the main beam 30 on the main beam member 20, which can support the weight of the rotor 5 for stable movement with respect to the rotor 5.

For example, the main beam member 20 is designed to be able to move a weight of 100 tons or more. The main beam member 20 includes a first lug 22 spaced at a predetermined interval on both sides of the main chain 30 so as to hold the main chain 30 with respect to the longitudinal direction, And a second lug (24) provided to prevent the main beam member (20) from directly colliding with the ground.

A plurality of first lugs 22 are disposed at regular intervals to hold one end of the main chain 30 in a locked state. The second lug 24 is located at the lower center of the main beam member 20 and may be formed in other shapes other than the polygonal shape shown in the drawings.

The first lug 22 is formed in an L shape and is engaged with the main chain 30 and a plurality of master rings 32 are engaged with the first lug 22 to move the rotor 5, do.

Although the storage unit unit 110 is shown in the form of a cube, the present embodiment can be configured in other forms.

The storage unit 110 includes a partition wall 112 for partitioning the interior of the main chain 30 and a wheel 113 spaced apart from the bottom of the storage unit 110, An extension portion 114 extending toward the upper side of the storage unit 110 and extending obliquely outwardly to the upper side of the storage unit 110; a ring provided on a front surface of the main chain 30, And a latching portion 116 in which the mastering ring 32 of the form is held in the locked state.

The main chain 30 is composed of a plurality of different weights each having a different allowable weight, and the main chain 30 is separately stored in an inner region divided into the barrier ribs 112.

For example, a first main chain having weight A and a second main chain having weight B may be stored, and the first main chain and the second main chain may be maintained at different weights.

The master ring 32 positioned at the front end of the main chain 30 weighs only tens of kilograms and the worker is required to work individually to engage the master ring 32 with the first lug 22 from the ground If you put it up, you may have an anomaly in your musculoskeletal system.

The present invention allows the master ring 32 to be moved forward and backward at the waist height of the operator when it is necessary for the operator to securely and easily engage the master ring 32 with the first lug 22, (Not shown).

The locking part 116 is formed in a structure in which the master ring 32 is formed in an elliptical shape and protrudes outwardly of the extension part 114, as shown in a corresponding form or in the figure.

That is, the latching portion 116 may be variously modified in addition to the form shown in the drawing in the case where the master ring 32 is retained and is not necessarily limited to the form shown in the drawings.

Since the extension part 114 according to the present embodiment extends obliquely outward and the engagement part 116 is also located at the extension part 114, when the master ring 32 is retained, It is located at an inclined angle with a similar degree of inclination angle.

It may be more advantageous for the operator to draw the master ring 32 outwardly of the latching portion 116 when the mastering ring 32 is sloped to the latching portion 116 and the first lug 22 may be more easily .

In addition, the worker can safely perform the operation without missing the master ring 32 in the process of holding the master ring 32 by hand and separating it from the locking portion 116.

In the present embodiment, the holding plate 116 is provided on the lower side to prevent the master ring 32 from falling down into the inner region divided by the partition walls 112.

Since the support plate 118 is positioned below the master ring 32, even if the worker slips or misses while separating the master ring 32 from the engagement portion 116, It is unnecessary to move the master ring 32 by bending the waist and the occurrence of a safety accident in which the master ring 32 is dropped by the operator's foot can be prevented in advance.

For example, when the main beam member 20 is lowered, the lowered position is stably maintained by first contacting the collision beam member 300 to be described later. In this case, the first lug 22 and the master ring 32 provided on the main beam member 20 are located at positions facing each other.

For example, the partition wall 12 divides the inside of the storage unit 110 into a grid shape or a cross shape, and the main chain 30 is located in the partitioned interior.

The inner region partitioned by the partition wall 12 is partitioned into a plurality of independent spaces, and the main chain 30 is respectively located therein.

The storage unit 110 according to the present embodiment is painted with a specific color in order to improve the visibility of the operator. In this case, when the main beam member 20 is lowered, the worker on the crane can accurately identify the exact lowering position with the naked eye, which improves the discrimination power.

The storage unit 110 is moved to the upper surface of the base plate 200 having the guide rails 210 guiding the entry and movement directions of the wheels 113, Replacement is done.

The base plate 200 is formed in a flat plate shape having a predetermined thickness and is positioned on the ground. The guide rails 210 extend from both ends of the guide rails 210 with a predetermined length in the longitudinal direction as viewed from the upper surface of the base plate 200. The guide rails 210 are spaced apart from each other with respect to the center of the upper surface of the base plate 200 Respectively.

The storage unit 110 is not always located on the base plate 200, but is provided with a wheel 113 on its lower surface so that it can be easily moved by an operator.

The guide rails 210 are formed such that grooves are formed to allow the wheel 113 to enter or the unit rails are positioned on both left and right sides of the wheel 113 with respect to the wheel 113. In this case, the wheel 113 can be easily moved forward or backward by the operator along the longitudinal direction of the guide rail 210.

The guide rails 210 are located on both sides of the upper surface of the base plate 200. The two storage units 110 are moved along the guide rails 210 and are positioned facing each other So that the positions facing each other remain the same.

Therefore, when the operator moves the storage unit 110 to the guide rail 210, the positions of the storage unit 110 spaced apart from each other are shifted in a specific direction or positioned at a predetermined position without inconsistency, .

Further, when the worker performs the work for installing the mastering ring 32 on the first lug 22, work can be performed with a minimum work line, and workability is improved.

The base plate 200 according to the present embodiment can be moved to the guide rail 210 through a crane. In this case, since an operator does not need to separately push or move the storage unit 110, Can be performed.

If an operator needs to move the storage unit 110 from the ground to the guide rail 210, the guide rail 210 may be provided at one end of the guide rail 210 to guide the initial entry of the storage unit unit 110 when the storage unit 110 is moved to the guide rail 210. As shown in FIG.

The guide unit 220 is provided in each of the plurality of guide rails 210 and is reduced in length in the width direction from the ground to the guide rails 210.

For example, when the operator moves the storage unit 110 in the direction in which the guide rail 210 is positioned, the guide unit 220 must be provided so that the height of the ground due to the thickness of the base plate 200 The storage unit 110 can be easily moved to the guide rail 210 regardless of the car.

Further, since the length of the guide portion 220 in the width direction decreases from the ground to the guide rail 210, when the operator enters the wheel 113 through the guide portion 220, even if the entry position deviates leftward or rightward The guide rail 210 can be easily moved.

5 to 7, the present embodiment is provided with a collision preventing unit 300 for preventing direct collision with the lower side of the main beam member 20 at the center of the upper surface of the base plate 200 . The collision avoidance unit 300 is extended higher than the height of the storage unit 110 and is first brought into contact with the lower surface of the main beam member 20.

The collision avoidance unit 300 may be provided on the bottom surface of the main beam member 20 when the operator moves the main beam member 20 upward from the seat of the crane, It is difficult to accurately recognize the difference in height between the upper surface of the storage unit 110 and the upper surface of the storage unit 110 and is used to prevent breakage and deformation of the main beam member 20 in advance.

Briefly summarized, the collision avoidance unit 300 prevents direct collision between the storage unit 110 and the main beam member 20, thereby creating a safe working environment.

The anti-collision units 300 may be positioned at the center of the upper surface of the base plate 200 or may be positioned facing each other at the center of the upper surface of the base plate 200, The end of the guide rail 210 and the one side of the anti-collision unit 300 are held in contact with each other.

Both the former and latter are selectively used in the field by the operator's choice and are not particularly limited. However, in the latter case, the collision preventing unit 300 is brought into contact with the end portion of the guide rail 210, and the operator can precisely position the storage unit 110 at a specific position after entering the guide rail 210 The two storage unit parts 110 can be positioned at the unfolding position.

The operator does not move from the floor to the first lug 22 when the master ring 32 is moved and moves toward the first lug 22 positioned at the opposite position in the locking portion 116, The moving operation for the master ring 32 is completed.

Therefore, when the operator performs the installation or separation work on the master ring 32, the safety is improved and a safe working space is ensured.

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 of the invention as set forth in the appended claims. The present invention can be variously modified and changed by those skilled in the art, and it is also within the scope of the present invention.
