[0001] The present invention relates to an attached ore recovery device for a reclaimer capable of receiving and recovering raw materials that are attached to and fall from a transporter of a reclaimer installed in a storage tank or open yard for raw material discharge. Background Technology

[0003] Generally, iron ore raw materials are stored in warehouses or open yards at steel mills. Multiple cells are formed within these warehouses or open yards to store the iron ore raw materials.

[0004] Rails are installed in the storage tank, and a reclaimer runs along the rails. The reclaimer is a device that discharges the stored iron ore raw materials and loads them onto a conveyor.

[0005] Two or more reclaimers are installed on the rail. Laser sensors are installed on the reclaimers to detect the location of adjacent reclaimers.

[0006] The background technology of the present invention is disclosed in Korean Published Patent Application No. 2007-0093718 (published September 19, 2007, title of invention: Reclaimer driving control system). The problem to be solved

[0008] The present invention aims to provide an attached ore recovery device for a reclaimer that can recover attached ore stored in the support member to a collection area of ​​the transporter without installing an additional separate drive unit, by providing a support member at a part where the direction of travel of the transporter changes so as to recover raw material falling outside the storage area attached to the transporter that discharges raw material, and by converting the power of the transporter into reciprocating motion in the forward and backward directions of the support member. means of solving the problem

[0010] The invention is characterized by comprising: a plurality of conveying members installed in a pulley section that circulates in an endless track to discharge raw materials; a support member installed opposite to a section where the direction of travel of the conveying member bends, for receiving raw materials falling from the conveying member; a frame section installed on a rotating member that supports the conveying member and supports the support member so that it can move forward or backward toward the conveying member; and a power transmission section that converts and transmits power provided to the conveying member into reciprocating motion of the support member.

[0011] The above frame portion may include: a support panel supported by a plurality of mounting brackets extending from the rotating member; a plurality of connecting members extending from the support panel; a fixed panel installed on the connecting members, into which a sliding shaft extending from the support member is slidably inserted; and a fixed block installed on the connecting members, into which the sliding shaft is slidably inserted, and positioned to maintain a distance from the fixed panel.

[0012] One end of the sliding shaft inserted into the fixed panel may be provided with a first stopper that catches on the fixed panel to prevent the sliding shaft from being separated from the fixed panel, and the other end of the sliding shaft may be provided with a first fixing part that connects the sliding shaft to the support member.

[0013] The power transmission unit may include: a driving pulley installed on a rotating shaft around which the pulley unit is wound and which rotates by the circulating motion of the pulley unit; a driven pulley rotatably installed on the frame unit; a transmission chain wound around the driving pulley and the driven pulley to transmit power to the pulley unit; and a conversion transmission unit that converts the rotational motion of the driven pulley into the reciprocating motion of the support member and transmits it.

[0014] The above conversion transmission unit may include a movable block connected to the sliding shaft by a second fixing part; a first link, one end of which is connected to the rotation axis of the driven pulley; and a second link, one end of which is rotatably connected to the other end of the first link and the other end of which is rotatably connected to the movable block.

[0015] The present invention may further include a discharge unit that pressurizes and discharges raw materials stored in the support member toward the transport unit when the support member retracts.

[0016] The discharge unit may include a pressure panel movably disposed on the support member; and a discharge pressure unit that restrains the pressure panel when the support member retracts away from the transport unit to discharge raw materials stored in the support member toward the transport unit.

[0017] The above discharge pressurizing member may include a pressurizing shaft extending from the pressurizing panel and slidably inserted into the sliding shaft; a sliding hole formed by opening a part of the sliding shaft; and a fixing member extending from the connecting member and inserted through the sliding hole to be connected to the pressurizing shaft. Effects of the invention

[0019] The attached light recovery device for a reclaimer according to the present invention has the advantage of being able to collect attached light falling from the transporter by installing a support member at the area where the attached light falls as the transporter's direction of travel changes, so that the attached light is attached to the back surface of the transporter that discharges raw materials from the storage tank and moves to the outside of the storage tank.

[0020] The attached ore recovery device for a reclaimer according to the present invention has a power transmission unit that converts and transmits power provided to a transport unit into reciprocating motion of a support member, so it can provide reciprocating motion that repeatedly moves forward or backward to the support member without installing a separate drive unit, thereby having the advantage of returning the raw material that falls from the transport unit and is stored in the support member in the downward direction of the transport unit, while resupplying the attached ore recovered in the support member to the recovery area of ​​the transport unit.

[0021] The attached light recovery device for a reclaimer according to the present invention further includes a discharge unit that pressurizes and discharges the raw material stored in the support member toward the transport unit when the support member retracts away from the transport unit. Therefore, since a technical configuration that physically pressurizes and discharges the raw material stored in the support member toward the transport unit is added, there is an advantage of being able to more effectively resupply the raw material to the collection area of ​​the transport unit.

[0022] The discharge section of the attached ore recovery device for a reclaimer according to the present invention comprises a pressure panel installed to be movable outward from the inner wall of a support member and a discharge pressure section that maintains the pressure panel in a fixed position regardless of the retraction operation of the support member. Since the pressure panel maintains a fixed state when the support member is retracted by the operation of the power transmission section, there is an advantage in that the raw material contained in the support member is pressured and discharged toward the transport section without adding a separate driving section.

[0028] Therefore, the definitions of these terms should be based on the content throughout this specification.

[0030] FIG. 1 is a drawing showing a storage tank with a reclaimer installed according to an embodiment of the present invention, FIG. 2 is a side view showing an attached light recovery device for a reclaimer according to an embodiment of the present invention, and FIG. 3 is a perspective view showing an attached light recovery device for a reclaimer according to an embodiment of the present invention.

[0032] Referring to FIGS. 1 to 5, an attachment ore recovery device for a reclaimer according to one embodiment of the present invention comprises a plurality of transport members (130) installed at spaced intervals on a pulley member (110) that circulates in an endless track to discharge raw materials, a support member (50) installed opposite to a point where the direction of travel of the transport member (130) bends to receive raw materials falling from the transport member (130), a frame member (30) installed on a rotating member that supports the transport member (130) and supports the support member (50) so that it can move forward or backward toward the transport member (130), and a power transmission member (70) that converts and transmits power provided to the transport member (130) into reciprocating motion of the support member (50).

[0033] The raw material dispensing member (100) including the conveying member (130) of the present embodiment is supported by a rotating member (200), and one end of the rotating member (200) is rotatably installed in the central part of the storage tank, and the other end of the rotating member (200) is movably installed along a rail (300) installed on the edge of the storage tank.

[0034] The raw material (S) is supplied from the outside via a conveyor belt (20), and the supplied raw material (S) is stacked on the inside of the rail member (300) using a stacker (10).

[0035] The stored raw material (S) is discharged through the raw material discharge member (100), and the raw material (S) is discharged as the raw material discharge member (100) is moved by the rotating member (200).

[0036] In this embodiment, the raw material dispensing member (100) includes a pulley part (110) that rotates using power such as a motor or engine, and a transport part (130) that moves in an endless track by the rotation of the pulley part (110) and moves the raw material (S).

[0037] Accordingly, when the pulley unit (110) is rotated by power such as a motor or engine, a plurality of transport units (130) move from the edge of the storage tank toward the center, discharging raw materials to the center of the storage tank, and as the transport units (130) pass through the inner end of the pulley unit (110), they change their direction of travel toward the edge of the storage tank and circulate in an endless track manner.

[0038] The transport unit (130), which has moved to the outer end of the pulley unit (110), changes its direction of travel toward the bottom surface of the storage unit and then changes its direction of travel toward the central part of the storage unit. At this time, the attached light attached to the back surface of the transport unit (130) can be separated from the transport unit (130) and discharged toward the rail (300).

[0039] In this embodiment, as described above, a support member (50) is installed so as to face the part where the direction of travel of the transport unit (130) changes, so that raw materials separated and discharged from the transport unit (130) are stored in the support member (50), thereby preventing the raw materials from being lost to the rail (300).

[0040] In addition, the present embodiment is equipped with a power transmission unit (70) that moves the support member (50) forward or backward toward the transport unit (130), so the raw material stored in the support member (50) is resupplied to the collection area of ​​the transport unit (130) as the support member (50) moves toward the transport unit (130) by the operation of the power transmission unit (70).

[0041] The frame portion (30) of the present embodiment includes a support panel (32) supported by a plurality of mounting brackets (38) extending from a rotating member (200), a plurality of connecting members (34) extending from the support panel (32), a fixed panel (36) installed on the connecting members (34) and into which a sliding shaft (52) extending from a support member (50) is slidably inserted, and a fixed block (37) installed on the connecting members (34), into which a sliding shaft (52) is slidably inserted, and arranged to maintain a distance from the fixed panel (36).

[0042] The support panel (32) is formed in the shape of a horizontally elongated panel, and a plurality of mounting brackets (38) installed at both ends are installed at the bottom of the rotating member, and the sliding shaft (52), the support member (50), and the power transmission part (70) are supported by a plurality of connecting rods (34) extending downward from the support panel (32).

[0043] A plurality of connecting rods (34) extending downward from the outer end of the support panel (32) are installed long in the left-right direction of the fixed panel (36), and one end of the sliding shaft (52) is inserted through the fixed panel (36).

[0044] A plurality of connecting rods (34) extending downward from the center of the support panel (32) are installed with a fixed block (37) into which a sliding shaft (52) is slidably inserted, and a conversion transmission unit (80) that moves the sliding shaft (52) forward or backward is connected between the fixed panel (36) and the fixed block (37).

[0045] At one end of the sliding shaft (52) inserted into the fixed panel (36), a first stopper (54) is provided to prevent the sliding shaft (52) from being separated from the fixed panel (36) by being caught on the fixed panel (36), and at the other end of the sliding shaft (52), a first fixing part (57) is provided to connect the sliding shaft (52) to a support member (50).

[0046] The stopper (54) includes a first nut member (56) installed at one end of the sliding shaft (52) and engaged with the fixed panel (36), and the first fixing part (57) includes a second nut member (58) fastened to the sliding shaft (52) and fixed to the back surface of the support member (50), and a third nut member (59) fastened to the sliding shaft (52) and fixed to the inner wall of the support member (50).

[0047] Accordingly, when the sliding shaft (52) moves forward or backward by the operation of the conversion transmission unit (80), the sliding shaft (52) is prevented from being separated from the fixed panel (36) by the first nut member (56), and the support member (50) fixed to the other end of the sliding shaft (52) performs a reciprocating motion that moves forward or backward by the amount of movement of the sliding shaft (52).

[0048] The power transmission unit (70) of the present embodiment includes a driving pulley (72) installed on a rotating shaft on which the pulley unit (110) is wound and rotated by the circulating motion of the pulley unit (110), a driven pulley (74) rotatably installed on a frame unit (30), a transmission chain (76) wound on the driving pulley (72) and the driven pulley (74) to transmit power of the pulley unit (110), and a conversion transmission unit (80) that converts the rotational motion of the driven pulley (74) into the reciprocating motion of the support member (50) and transmits it.

[0049] Accordingly, when the driving pulley (72) is rotated by the power transmitted to the pulley unit (110), the transmission chain (76) circulates to transmit power to the driven pulley (74), and the sliding shaft (52) performs a reciprocating motion that repeatedly moves forward or backward by the operation of the conversion transmission unit (80) connected to the rotation axis of the driven pulley (74).

[0050] The conversion transmission unit (80) includes a moving block (82) connected to a sliding shaft (52) by a second fixing unit (87), a first link (84) with one end connected to the rotation axis of a driven pulley (74), and a second link (86) with one end rotatably connected to the other end of the first link (84) and the other end rotatably connected to the moving block (82).

[0051] Therefore, when the rotation axis of the driven pulley (74) rotates, the first link (84), which is relatively short, rotates and repeats the pulling and pushing operation of the second link (86), which is relatively long, so that the sliding shaft (52), whose lifting movement is restricted by the fixed panel (36) and fixed block (37), repeats the reciprocating motion of moving forward or backward.

[0052] Accordingly, when one of the multiple transport units (130) rotates from the upper side to the lower side along the pulley unit (110) and the direction of travel is changed, the attached light attached to the back surface of the transport unit (130) is separated from the transport unit (130) by the centrifugal force of the rotating transport unit (130) and discharged toward the rail (300). At this time, the raw material is stored in the support member (50) advancing toward the pulley unit (110), thereby preventing the raw material from being lost toward the rail (300).

[0053] As described above, the support member (50) containing the raw material moves backward and then forward again by means of a propulsive force that discharges the raw material contained in the support member (50) to a collection area of ​​the transport unit (130), and then moves backward again by collecting the raw material discharged from another transport unit (130) that changes direction.

[0054] Therefore, the raw material discharged from the transport unit (130) is stored in the support member (50) that repeatedly moves forward and backward, and then supplied back to the collection area of ​​the transport unit (130), thereby preventing the raw material from being lost to the rail (300).

[0055] The second fixing part (87) of the present embodiment includes a fourth nut member (88) that is fastened to the sliding shaft (52) and fixed to the back surface of the movable block (82), and a fifth nut member (89) that is fastened to the sliding shaft (52) and fixed to the front surface of the movable block (82).

[0056] Unexplained reference numeral 82a is a hinge shaft (82a) that protrudes from both sides of the movable block (82) and to which the second link (86) is rotatably connected.

[0058] FIG. 6 is a cross-sectional view showing the discharge section of an attached light recovery device for a reclaimer according to one embodiment of the present invention.

[0059] Referring to FIG. 6, the attached light recovery device for a reclaimer according to another embodiment of the present invention further includes a discharge unit (90) that pressurizes and discharges raw material stored in a support member (50) toward the transport unit (130) when the support member (50) retracts, so that raw material discharged from the transport unit (130) is stored when the support member (50) advances, and raw material stored is discharged from the support member (50) by the operation of the discharge unit (90) when the support member (50) retracts.

[0060] The discharge unit (90) of the present embodiment includes a pressure panel (92) movably disposed on a support member (50), and a discharge pressure unit (94) that restrains the pressure panel (92) when the support member (50) retracts away from the transport unit (130) to discharge raw materials stored in the support member (50) toward the transport unit (130).

[0061] Therefore, when the support member (50) retracts, the pressure panel (92) does not retract and remains fixed in a certain position, so that the raw material contained in the support member (50) is provided with an external force pressing outward from the support member (50) and can be discharged from the support member (50).

[0062] The discharge pressurizing part (94) of the present embodiment includes a pressurizing shaft (96) that extends from the pressurizing panel (92) and is slidably inserted into the sliding shaft (52), a sliding hole part (98) formed by opening a part of the sliding shaft (52), and a fixing member (97) that extends from the connecting member (34), is inserted through the sliding hole part (98), and is connected to the pressurizing shaft (96).

[0063] Since the connecting member (34) and the fixed member (97) are supported by the support panel (32), they do not advance or retract and remain fixed in a fixed position. Therefore, when the sliding shaft (52) and the support member (50) advance or retract, the pressure panel (92) located inside the support member (50) exhibits the effect of advancing or retracting within the support member (50), thereby enabling the raw material to be discharged to the outside of the support member (50).

[0064] By operating the pressure panel (92) as described above, no attached light remains on the inner wall of the support member (50), and the raw material stored in the support member (50) can be resupplied to the collection area of ​​the transport unit (130).

[0065] Thus, a device for recovering attached ore for a reclaimer can be provided, which can recover the attached ore stored in the support member to a collection area of ​​the transport member without installing an additional separate drive unit, by providing a support member at the part where the direction of travel of the transport member changes so that the raw material falling from the transport member can be recovered, and the power of the transport member can be converted into reciprocating motion in the forward and backward directions of the support member.

[0067] Although the present invention has been described with reference to an embodiment illustrated in the drawings, this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom.

[0068] In addition, although an attached light recovery device for a reclaimer has been described as an example, this is merely illustrative, and the recovery device of the present invention may be used for other products other than an attached light recovery device for a reclaimer.
