Description

Technology Field

[0001] The present invention relates to a feeding device that is used in conjunction with a press for forming a towing hook, and is expected to ensure worker safety and ease of maintenance during the wire rope feeding process. Background Technology

[0002] Generally, a towing ring is formed from a metal material having a predetermined length of wire rope, and a ring shape is formed on one or both sides of the wire rope to be used for towing an object with a load. As shown in FIG. 1, a horseshoe-shaped metal body (10) is mounted inside the ring shape, and then pressure-molded by a press or the like to prevent the wire rope itself from being damaged.

[0003] When forming the above-mentioned pintle hook (P / H), a feeding device may be used in close proximity to the press, and a process is executed in which a wire rope bearing a load is moved in a sleeve locking manner using the power of such a feeding device, and while the wire rope and the metal body are in close contact, a fixed connection between the wire rope and the metal body is made possible through the application of pressure from the press.

[0004] A conventional feeding device satisfies the structure in which, to satisfy the above-mentioned function, at least one feeding roller, which rotates by receiving power from a motor, is rotatably mounted on a base, and a pressure roller is rotatably mounted on the base above the feeding roller.

[0005] Meanwhile, in the case of the aforementioned conventional feeding device, the feeding roller and pressure roller are rotatably mounted inside the base to prevent safety accidents for workers, so there is an inconvenience in that maintenance can only be performed after dismantling the base.

[0006] For example, conventional feeding devices, which require an operator to visually identify the degree of pressure applied to wire ropes of different outer diameters and determine whether the wire rope is accurately inserted between the outer surface of the feeding roller and the outer surface of the pressure roller or whether the degree of pressure is appropriate, do not possess structural features capable of satisfying this requirement, thereby causing the inconvenience of disassembling the base.

[0007] Of course, there is the inconvenience of having to dismantle the base itself to perform maintenance even if the feeding wire rope deviates from the designated space—specifically, the space between the feeding roller and the pressure roller—during the movement process. Prior art literature

[0011] Additionally, the opening and closing means (130) preferably includes a through hole (131) formed on the outer surface of the upper body (120) to communicate with the space (124) where the feeding member (200) is installed, a door plate (132) rotatably coupled to the upper body (120) to open and close the through hole (131), a locking member (133) provided on the upper body (120) to fix or release the upper part of the door plate (132), and a hinge (135) which is connected to the lower part of the door plate (132) on one side and connected to the upper body (120) on the other side so that the door plate (132) can rotate.

[0012] Additionally, it is preferable that the position of the through hole (131) be formed so that when the door plate (132) is opened, the wire rope (C) conveyed by the feeding member (200) can be exposed to the outside through the through hole (131).

[0013] Additionally, the base (100) further includes a reinforcing bracket (140) for reinforcing the impact of the upper body (120) on which the opening / closing means (130) is formed, wherein the reinforcing bracket (140) is preferably formed by bending so that its upper part is connected to the upper body (120) and its lower part is connected to the lower body (110).

[0014] Additionally, the feeding member (200) preferably includes a feeding roller (210) on which a wire rope (C) is seated, which is rotated by a driving motor (111) and has an anti-slip groove (H) formed on its outer surface, and a pressure roller member (220) which is mounted to be vertically movable with respect to the base (100) and positioned above the feeding roller (210), thereby adjusting the degree of pressure applied to the wire rope (C) by the vertical movement. Effects of the invention

[0015] According to the present invention, in the event that a problem occurs where the wire rope detaches from the feeding roller or pressure roller during the process of feeding the wire rope to form a towing hook, the operator can expect the effect of quickly resolving the problem through maintenance by opening the door plate with the drive motor stopped and through the through hole.

[0020] Furthermore, in describing the present invention, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the essence of the invention, such detailed description is abbreviated or omitted.

[0022] Hereinafter, a wire rope feeding device dedicated to sleeve locking according to the present invention (hereinafter briefly referred to as the "feeding device") will be described in detail with reference to the attached drawings.

[0023] First, as illustrated in FIG. 2, the feeding device (1) according to the present invention mainly comprises a base (100) and a feeding member (200).

[0024] To explain in more detail, the base (100) is configured to provide space and power for feeding a wire rope (C) by the feeding member (200) as described later, as shown in FIGS. 3 to 5, and includes a lower body (110), an upper body (120), an opening / closing means (130), and a reinforcing bracket (140).

[0025] For example, as illustrated, the lower body (110) is formed using a bracket having lengths in the horizontal and vertical directions so that a drive motor (111) can be mounted inside, and a plurality of wheels (112) are installed on the lower part to move and fix the lower body (110) to a desired location.

[0026] Additionally, as illustrated, the upper body (120) includes a first plate (121), a second plate (122), a spacing bar (123), and a fastening rib, configured to provide a space through which a wire rope (C) can be inserted so as to be fed, in which a pair of feeding members (200) to be described later are installed.

[0027] The first plate (121) is positioned vertically on the upper part of the lower body (110) to have the shape of a plate overall, and is installed so as to be fixed by a plurality of fastening ribs.

[0028] A perforation is formed on the outer surface of the first plate (121), and through the perforation, the condition of the wire rope (C) through which feeding is performed, as well as whether the feeding member (200) is operating, can be easily checked visually.

[0029] As illustrated, the second plate (122) is configured as a pair facing each other with the first plate (121) described above and is installed to be fixed to the first plate (121) through a spacing bar (123).

[0030] That is, one of the pair of second plates (122) is fixedly connected to the lower body (110), and the other is positioned on the upper part of the second plate (122) connected to the lower body (110) and is installed to be fixedly connected to the first plate (121) through a spacing bar (123).

[0031] At this time, it is preferable that a pair of second plates (122) be installed so as to be fixed to the first plate (121) through a plurality of spacing bars (123) so that a through hole (131) can be formed by being adjacent to each other in the vertical direction, and that the through hole (131) is opened and closed through the rotation of the door plate (132) to be described later.

[0032] In addition, the height of the second plate (122) installed on the upper part of a pair of second plates (122) is fixed by a spacing bar (123) to be the same as the upper height of the first plate (121), thereby ensuring stable mounting of the installation piece (222) constituting the feeding member (200) described later, so that the lifting body (221) can be raised and lowered vertically.

[0033] In particular, the second plate (122) provided on the upper part of a pair of second plates (122) has a lifting groove formed on its outer surface for the lifting body (221) to lift and lower, and in addition to the lifting groove, another perforation is formed opposite to the perforation formed in the first plate (121) described above, so that a worker can easily visually check whether the feeding member (200) is operating, as well as the condition of the wire rope (C) being fed by the feeding member (200), from at least one direction of the first plate (121) or the second plate (122).

[0034] Furthermore, a rotational hole may be formed on the outer surface of the second plate (122) that is connected to the lower body (110) among a pair of second plates (122) so that a feeding roller (210) constituting the feeding member (200) can be rotatably inserted through it.

[0035] Meanwhile, between the first plate (121) and a pair of second plates (122) connected to each other through the aforementioned spacing bar (123), a space (124) is naturally formed through the spacing bar (123), thereby allowing for the installation of a pair of feeding members (200) in the space (124) as well as the formation of a space for a wire rope (C) to be inserted through.

[0036] To this end, the spacing bar (123) is formed into a cylindrical shape having a predetermined length as shown in the illustration, and may have screw threads formed on its outer surface so as to be screw-coupled with a fastening means inserted through the outside of the first plate (121) or the second plate (122).

[0037] The fastening rib includes a main fastening rib (125) and an auxiliary fastening rib (126) configured to support and reinforce so that the fixing force of one of the first plate (121) and a pair of second plates (122) disposed on the upper surface of the lower body (110) can be maintained.

[0038] As described above, the main connecting rib (125) has a shape formed by bending so that its lower surface contacts the upper surface of the lower body (110) and its side surface contacts the outer surface of the first or second plate (121, 122), and a fastening means is fastened through each contact position to help the first and second plates (121, 122) be fixedly installed on the lower body (110).

[0039] In addition, the auxiliary fastening rib (126) is positioned on both sides of the main fastening rib (125) to have the same shape as the main fastening rib (125), with its lower surface in contact with the upper surface of the lower body (110) and its side surface in contact with the outer surface of the first or second plate (121, 122) so that they can be mutually fastened by a fastening means to improve the fixing force.

[0040] Additionally, the opening and closing means (130) includes a door plate (132), a locking member (133), and a hinge (135) in a configuration that allows a worker to maintain the wire rope (C) fed through a pair of feeding members (200) without disassembling the first and second plates (121, 122) by opening and closing the aforementioned through hole (131).

[0041] As illustrated, the door plate (132) can be formed into the shape of a plate, and the lower part is rotatably connected to the second plate (122) through a hinge (135), and the upper part is installed so that rotational connection or release is possible by a locking member (133).

[0042] At this time, it is preferable to form the area of ​​the door plate (132) larger to correspond to the area of ​​the through hole (131) so that the entire through hole (131) can be covered from the outside through the door plate (132) when the through hole (131) is closed.

[0043] Here, the locking member (133) refers to a conventional latch that can fix or release the door plate (132) by being installed on the outer surface of the upper second plate (122) of a pair of second plates (122) as described above, and a detailed description is omitted so as not to obscure the gist of the invention.

[0044] Meanwhile, the position of the through hole (131) in the present invention is formed so that the wire rope (C) fed through a pair of feeding members (200) can be exposed to the outside when the door plate (132) is open, thereby allowing the operator to easily perform maintenance of the feeding device (1) according to the present invention simply by opening the door plate (132).

[0045] Additionally, as shown in the illustration, the reinforcing bracket (140) is connected at its upper end to the upper second plate (122) of a pair of second plates (122), and at its lower end to the upper surface of the lower body (110), so as to provide reinforcement such as vibration absorption together with the aforementioned connecting ribs in response to vibrations, etc., that occur when the wire rope (C) is fed by a pair of feeding members (200).

[0046] To this end, the reinforcing bracket (140) in the present invention can be formed into the shape of a column, and the upper part can be formed into a bent shape for fastening with the second plate (122).

[0047] And, as shown in FIGS. 6 and 7, the feeding member (200) is configured to feed a wire rope (C) inserted through the space (124) by applying pressure and rotation, and includes a feeding roller (210) and a pressure roller member (220). In the present invention, a pair of the feeding members (200) are installed adjacent to each other on the space (124), and it should be noted that one of the feeding members (200) is shown below to clearly convey the gist of the present invention.

[0048] For example, as illustrated, the feeding roller (210) has the shape of a roller such that one side is rotatably coupled to the first plate (121) and the other side is rotatably coupled to the second plate (122), and a groove is formed on the outer surface for inserting the lower surface of the wire rope (C).

[0049] The rotation axis of the feeding roller (210), which is rotatably coupled to the first plate (121), is installed to have a structure that allows it to penetrate the first plate (121) and be exposed to the outside, and a sprocket (211) is fixedly mounted on the outer surface of the rotation axis exposed to the outside.

[0050] At this time, the sprocket (211) is installed so that a chain (212) connected to the above-described drive motor (111) can be wound around it, and it is preferable that power be transmitted and the wire rope (C) can be fed according to the rotational direction of the drive motor (111).

[0051] Of course, the above-mentioned chain (212) is connected to a pair of sprockets (211) corresponding to a pair of feeding members (200) and transmits power through a single drive motor (111) so that the pair of sprockets (211) can rotate in one direction.

[0052] Additionally, the pressure roller member (220) is configured to rotatably press the upper surface of the wire rope (C) inserted into the above-described feeding roller (210) so that the wire rope (C) can be stably fed, and includes a lifting body (221), an installation piece (222), a screw (223), and a pressure roller (225).

[0053] As shown in the illustration, the lifting body (221) is formed into an overall 'U' shape with an open bottom, and is installed so as to be able to move up and down along lifting grooves formed on both sides of the first and second plates (121, 122) facing each other.

[0054] Inside the lifting body (221), a pressure roller (225) is rotatably coupled to the shaft, and the shaft is screw-coupled to the screw (223) so as to be tooth-coupled, thereby generating power to move up and down according to the rotational direction of the screw (223).

[0055] As shown in the illustration, the installation piece (222) is formed into the shape of a plate, and a screw (223) that can be rotated through a handle (224) provided on the upper part is inserted through it so that it can be screwed in.

[0056] The lower surface of the installation piece (222) is in contact with the upper surfaces of the first and second plates (121, 122) so as to be supported, and is fixedly installed on the first and second plates (121, 122) using fastening means for fixation, thereby allowing the screw (223) to respond to vibrations that may occur when it rotates.

[0057] As shown in the illustration, the pressure roller (225) is configured to have the same structure as the feeding roller (210), differing only in diameter, so that both sides can be rotatably coupled to the lifting body (221).

[0058] That is, the pressure roller (225) may have a groove formed on its outer surface so that the upper surface of the wire rope (C) can be inserted in contact with it, just like the feeding roller (210), and when the wire rope (C) is fed in one direction through the rotation of the feeding roller (210), power is transmitted to rotate the pressure roller (225) by the moving force of the wire rope (C).

[0059] Thus, through the pressure and rotation between the feeding roller (210) and the pressure roller (225), feeding is performed so that the wire rope (C) does not detach from the groove formed on the outer surface of each roller.

[0060] If, during the process of feeding the wire rope (C), the pressure of the screw (223) decreases or the wire rope (C) detaches from the groove due to vibrations occurring when the feeding device (1) according to the present invention is operated, the operator can perform rapid maintenance by opening the door plate (132) while the feeding device (1) is stopped.

[0061] Meanwhile, on the outer surface of the groove formed in each of the feeding roller (210) and the pressure roller (225) in the present invention, an anti-slip groove (H) is formed in an intaglio or embossed shape so that the wire rope (C) fed by pressure and rotation can be fed more stably.

[0062] As described above, as illustrated in FIGS. 8 and 9, when the wire rope (C) is fixed so that the metal body (10) is fitted through the press (20) and the wire rope (C) is pulled by the feeding device (1) according to the present invention, the metal body (10) is fitted and coupled to the outer surface of the wire rope (C). Then, after stopping the feeding device (1) for a moment in this state, the forming of the traction hook (P / H) is stably achieved by applying pressure with the press (20).

[0063] As described above, the feeding device (1) according to the present invention, unlike conventional devices, allows for the effect of quickly resolving the problem through maintenance by opening the door plate (132) with the drive motor (111) stopped and through the through hole (131) when a problem occurs in which the wire rope (C) detaches from the feeding roller (210) or the pressure roller (225) during the process of feeding the wire rope (C) to form a traction hook (P / H).

[0065] As described above, the present invention has been explained by specific details such as specific components, limited embodiments, and drawings; however, this is provided merely to aid in a more comprehensive understanding of the invention, and the invention is not limited to the above embodiments. A person skilled in the art can make various modifications and variations from this description.

[0066] Accordingly, the scope of the present invention should not be limited to the described embodiments, and all things equivalent to or having equivalent variations to the claims set forth below, as well as the claims set forth below, shall be considered to fall within the scope of the concept of the present invention.
