BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a drawing device, and more particularly, to a drawing device capable of quickly recovering an accessory device entering a material container during operation of various facilities.

The coke plant used in the coke manufacturing process is a system in which cohesive coal is charged into a carbonization chamber provided in a coke oven to block air and is heated at high temperature to produce a hard white color coke And coke oven gas.

When the carbonization of the coke is completed, the coke is extruded out of the carbonization chamber by a ram. Subsequently, the call is supplied to the inside of the carbonization chamber through the intestinal inlet formed through the upper end of the carbonization chamber. Calls that pass through the entrance of the hall fall down to the bottom of the carburizing chamber and accumulate sequentially from the bottom of the carburizing chamber to a height close to the entrance of the bowling hall. On the upper surface of the call, a curved surface in the shape of a peak is formed around the entrance of the bow. When a predetermined amount of the call is charged into the carbonization chamber, the leveler enters the inside of the carbonization chamber via the leveler door formed on the upper side of the carbonization chamber and contacts the curved upper surface of the charged call, And flatten it. A predetermined space is provided between the upper surface of the flattened call and the inner surface of the carbonization chamber facing the flattened call, thereby forming a gas movement path. A large amount of byproduct gas originating from the call during operation can be smoothly guided to the uprising pipe provided at the upper end of the carbonization chamber through the formed gas moving path and can be easily discharged to the outside of the carbonization chamber.

The leveler receives power from a driving unit provided in the leveler, enters the inside of the carbonization chamber, and advances and retreats in the entering direction, thereby flattening the curved upper surface of the call which contacts the leveler. At this time, there is a case where the caller, which is in contact with the leveler while entering the inside of the carbonization chamber, restricts the movement of the leveler due to friction force exceeding the leveling force of the leveler on the leveler or damage to the leveler driving portion do. As a result, the leveler remains in the carbonization chamber for a time longer than the normal operation time of the leveler, and thermal deformation and disposal phenomenon due to high temperature heat inside the carbonization chamber may occur. Further, in order to retrieve the leveler remaining in the carbonization chamber, a plurality of operation personnel approaches the leveler, connects the chain block to the leveler, and operates the chain block to recover the leveler. do.

If the leveler can not be smoothly drawn out from the inside of the carbonization chamber, the leveler is damaged by the high temperature inside the carbonization chamber and the operation of the coke plant is delayed during the leveler recovery operation. Therefore, additional costs are incurred. In addition, it is possible to cause an operator's accident due to a flame and a high temperature which can be discharged from the inside of the carbonization chamber to the outside during the leveler withdrawal operation of a plurality of working personnel.

The forward and backward movement of the drum 21 in the lateral direction is transmitted to the leveler 22 through the transmission path formed along the longitudinal direction of the wire rope 300. [ The drawing apparatus 1000 provides a driving force to the leveler 22 that can act on the leveler 22 independently of the power transmitted to the leveler 22 by the driving unit provided in the leveler 22, ) To the outside of the coke oven (10).

The first rope retainer 110 is mounted, for example, by welding to the end of the leveler 22 facing the backward direction of the leveler 22. [ Also, the second rope hook 120 is mounted, for example, by welding to the end of the loupe 21 facing the backward direction of the loupe 21. The shape and size of the rope hooks 100 (110, 120) are not particularly limited. The rope hanger 100 prevents deformation or breakage of the rope hanger 100 in the process of transmitting the driving force applied to the rope hanger 100 by the wire rope 300 to the leveler 22 coupled to the rope hanger 100. [ Shape and size. The rope hook 100 may have the shape of a typical hook used in lifting devices such as, for example, a chain block and a crane. The rope hanger 100 corresponds to the nominal diameter of the wire rope 300 used in the drawing apparatus 1000 and the wire rope 300 in the area contacting the rope hanger 100 receives an excessive bending load It is possible to have a thickness that can be prevented. The rope hanger 100 is mounted toward the support unit 200 and is mounted so that the center position of the rope hanger 100 is aligned with the longitudinal center axis of the leveler 22 and louver 21, The rope hook 100 is formed with an open section in which the joint 310 of the wire rope 300 can be engaged. The open section is formed in a predetermined length toward the leveler 22 and the lamb 21 mounted at the center position of the rope hook 100 or upward of the center position of the rope hook 100. The pulling direction of the wire rope 300 acting on the rope hook 100 and the opening portion of the rope hook 100 are formed opposite to each other so that when the wire rope 300 applies a force to the rope hook 100, It is possible to prevent the rope hanger 100 from departing from the rope hook 100 through the section.

The support unit 200 includes a first sheave 210 that is aligned with the center axis of the leveler 22 and a second sheave 220 that is spaced apart from the lower side of the first sheave 210 in a direction toward the end of the ram 22 And a sheave support 230 which intersects the central axis of the leveler 22 and is provided with a rotation axis on which a plurality of sheaves 210 and 220 are mounted. The pulley support portion 230 is mounted to one side of the pusher car 20 by welding, for example, at a position where the pulleys 210 and 220 are installed. The pulleys 210 and 220 are provided with through holes passing through opposite side surfaces of the pulleys 210 and 220. The pulleys 210 and 220 are connected to the pulley support portions 230 so that the pulleys 210 ). The rotation shaft of the first sheave 210 is positioned in a direction crossing the center axis of the leveler 22 and the shaft of rotation of the second sheave 220 is positioned at a predetermined angle from the rotation shaft of the first sheave 210. The wire rope 300 connecting the end portion of the leveler 22 with the louver 21 spaced apart in the space can be easily moved along the support unit 200. The diameter of the pulleys 210 and 220 has a length equal to or greater than the radius of curvature of the wire rope 300 at the bending stress at which the wire rope 300 can withstand. It is possible to suppress or prevent damage due to the bending of the wire rope 300 contacting the pulleys 210 and 220. The ends of the sheaves 210 and 220 contacting the wire rope 300 form a predetermined thickness. Grooves having a depth corresponding to the nominal diameter of the wire rope 300 are formed along the rotating direction of the sheaves 210 and 220 in the direction toward the rotating shaft at the ends of the pulleys 210 and 220.

A guide roller 400 is mounted at the end of the drum 21 in the direction toward the support unit 200 at the end where the rope hook 100 of the drum 21 is mounted. The guide roller 400 is freely rotatable with a rotation axis crossing the longitudinal center axis of the drum 21. The guide roller 400 has a function of preventing the wire rope 300 from sagging when it contacts the wire rope 300 when the other end of the wire rope 300 is connected to the rope hook 100 mounted on the drum 21 do. Thus, the other end of the wire rope 300 connected to the rope hook 100 can be prevented from being detached from the rope hook 100. Further, the direction of the pressure applied to the wire rope 300 varies in accordance with the moving direction of the drum 21 of the guide roller 400. The wire rope 300 is brought into contact with the lower portion of the guide roller 400 at the time of advancement of the lantern 21 so that the guide roller 400 applies pressure downward to the contact surface with the wire rope 300. The wire rope 300 is brought into contact with the guide roller 400 at one side of the guide roller 400 facing the backward direction of the lantern 21 so that the guide roller 400 rotates the wire rope 300 To the contact surface with the back surface of the drum 21.

During the coal charging of the coke plant 1, the leveler 22 contacts the upper surface of the advancing call into the interior of the coke oven 10 to level the top surface of the loaded call. At this time, if the leveler 22 in contact with the call is not easily recovered to the outside of the coke oven 10 due to the damage of the driving portion and the pressure of the call contacting the leveler 22, Used in combination. One end of the wire rope 300 is inserted and connected to the first rope hook 110 mounted on the end of the leveler 22. [ Subsequently, the wire rope 300 is brought into contact with the upper portion of the first sheave 210 and is bent downward a predetermined distance downward in the backward direction of the leveler 22 along the contact surface formed and contacted with at least a part of the first sheave 210 do. Thereafter, the wire rope 300 is guided along the end of the ram 21. Subsequently, the wire rope 300 contacts the guide roller 400, and the other end of the wire rope 300 is inserted into the second rope hook 120 to form a pull-out path. Alternatively, the wire rope 300 may subsequently contact the second sheave 220 and the guide roller 400, and the other end of the wire rope 300 may be inserted into the second rope hook 120 to form a pull-out path. The different drawing paths formed by the contact state of the wire rope 300 are formed as follows according to the relative positions of the second sheave 220 and the guide roller 400 and the moving direction of the drum 21 as follows.

3 (a), when the lantern 21 is advanced toward the coke oven 10, the drawing path of the drawing apparatus 1000 is formed as follows. The wire rope 300 in contact with the first sheave 210 and guided along the path is bent downward a predetermined distance toward the drum 21 and contacts the lower portion of the guide roller 400. The other end of the wire rope 300 is inserted and connected to the first rope hook 110 mounted on the end of the ram 21. A transmission path is formed in which the louver 21 is connected to the leveler 22 so that the driving force of the loupe 21 can be transmitted to the leveler 22. The wire 21 advances and thus the wire rope 300 connected to the lantern 21 also moves in the advancing direction of the lantern 21 along the drawing path formed by the supporting unit 200. [ A force is applied to the end of the first rope hook 110 connected to one end of the wire rope 300 and the leveler 22 connected thereto in the backward direction. Thus, the leveler 22 is retracted and drawn out of the coke oven 10. At this time, one end of the slider 21 approaches the second sheave 220, and at least part of the wire rope 300 contacts the second sheave 220 when moving toward the coke oven 10. The wire rope 300 is separated from the second sheave 220 when the ram 21 continues to advance and one end of the ram 21 and the second sheave 220 move away from each other and the ram 21 advances, The wire rope 300 forms a pull-out path in contact with the first sheave 210 and the guide roller 400.

Referring to FIG. 3 (b), the draw path of the drawer 1000 is formed as follows when the drum 21 is moved backward while the drum 21 advances a predetermined distance toward the coke oven 10. The wire rope 300, which is in contact with the first sheave 210 and is routed toward the second sheave 220, is in contact with the upper portion of the second sheave 220. The wire rope 300 is deflected a predetermined distance along the contact surface with the second sheave 220 towards the ram 21 and is contactably supported at least at a part of the end of the second sheave 220. The other end of the wire rope 300 is inserted and connected to the second rope hanger 120 mounted on the end of the rack 21. A draw path is formed in which the louver 21 is connected to the leveler 22 so that the driving force of the loupe 21 can be transmitted to the leveler 22. The wire 21 is retracted, and the wire rope 300 moves along the transmission path. At this time, the guide roller 400 mounted on the end of the drum 21 comes into contact with the wire rope 300 and exerts a force on the contact surface with the formed wire rope 300 in the backward direction of the drum 21. The wire rope 300 moves along the take-out path, and a force is applied to the leveler 22 connected to one end of the wire rope 300 in the backward direction. Thus, the leveler 22 is retracted and drawn out of the coke oven 10. That is, the drawer 1000 can move the leveler 22 backward even if the drum 21 advances due to the relative position of the second pulley 220 and the guide roller 400, (22) can be reversed. Thereafter, the coke plant 1 can proceed with the call loading and operation.

Although the above embodiment of the present invention exemplifies the case of the coke plant, it can also be applied to the withdrawal of the subsidiary equipment required during the operation of various other facilities. It should be noted, however, that the above-described embodiments of the present invention are for the purpose of explanation and not for the purpose of limitation. It is to be understood that various modifications may be made by those skilled in the art without departing from the scope of the present invention.
