Description

Technology Field

[0001] The present invention relates to a foldable pallet for loading excavator motors, and more specifically, to a pallet for loading excavator motors that allows the edge fence and internal motor support to be folded when not in use, thereby significantly improving ease of use and transport efficiency, and enabling excavator motors of various sizes to be loaded in various ways. Background Technology

[0002] Generally, during the import and export of automobiles, pallets for automotive parts are loaded and secured in a disassembled state—containing various components such as engines, transmissions, motors, and car bodies—rather than as finished products. Multiple pallets are then stacked within a container, and several containers are loaded onto a ship to enable the transport of large quantities over long distances while minimizing damage to the automotive parts.

[0003] As disclosed in Korean Utility Model Publication No. 37293 of 1996 (published on December 16, 1996), a technology was developed to provide an engine pallet in which a urethane support member is attached to a urethane support plate to secure the engine, etc., in a supported state. However, since the pallet with the urethane support member attached to the urethane support plate lacks a support fence or support at the edge, it cannot be stacked in multiple layers in a container for loading onto a ship, which significantly reduces logistics efficiency. Consequently, it cannot be used for long-distance transportation by ship and can only be partially used for short-distance transportation via a conveyor inside a factory. Furthermore, because the loading object, the engine, is loaded using only the urethane support member, the loading object can easily fall from the pallet due to external impact or the sudden stop of the conveyor.

[0004] As disclosed in Korean Registered Utility Model No. 263086 (published on February 2, 2002), although it was possible to partially prevent the loaded object from escaping to the outside by using a supporter that serves as a border or fence rather than directly supporting the loaded object at the edge, it had a problem in that the efficiency of the transport logistics was significantly reduced because the supporter could not be folded in multiple layers at a designated location since it was not a structure that could be folded after transporting the loaded object. Accordingly, as disclosed in Published Patent No. 46699 of 2013 (published on May 8, 2013), in the case of a pallet for transporting a vehicle body, the front supporter and rear supporter that support the vehicle body, which is the loaded object, were folded into a base frame to minimize the volume and enable multiple pallets to be stacked in multiple layers, but it had a problem in that safety was reduced during transport of the loaded object due to members such as fences at the edge of the base frame.

[0005] In order to supplement the existing pallets for loading vehicle parts, etc. as described above, as disclosed in Korean Published Patent No. 46708 of 2013 (published on May 8, 2013), front and rear pivoting fences are installed to pivot on the front and rear mounting brackets of a base frame and rotate inwardly facing each other. Fixing bars are installed on both sides between the front and rear pivoting fences to provide support, and a front supporter and a rear supporter, on which the loading object (an engine) is placed and fixedly supported, are installed to be coupled and separated from the base frame. When the engine is placed, the front and rear supporters are fixed in an upright position, and after transporting the engine, they are fixed in a horizontal position. After laying the front and rear supporters down, a pair of left and right fixing bars are separated, a pair of front and rear pivoting fences are folded to the base frame, and the fixing bars are fixed to the base frame to reduce volume, thereby enabling multi-layer stacking so that pallets can be transported in large quantities after the engine is transported. However, when separating a pair of left and right fixing bars and a pair of front and rear supporters, It had numerous problems, such as the inconvenience of having to lay it down and combine it again, and the fact that the front and rear supports cannot be adjusted and applied when the size of the load varies, so pallets with different installation positions for the front and rear supports must be provided for each load, and thus, even when the size of the same load varies, various types of pallets must be provided for each size, which leads to significantly reduced logistics efficiency and a significant increase in manufacturing costs.

[0017] The present invention aims to provide a foldable pallet for loading excavator motors that allows for more efficient loading of various excavator motors as a loading object, and enables the pallet, including the edge fence and the internal supporter for loading the motor, to be foldable when not in use, thereby eliminating the need for individual storage or individual fixing after separation, thus significantly improving transport efficiency by minimizing volume and convenience of use, and allowing excavator motors of various sizes to be loaded in various ways, ranging from two to four. This will be explained in more detail below with reference to the drawings, provided that the attached drawings are merely examples to easily explain the content and scope of the technical concept of the present invention and are not limited thereto, and the terms used are also intended only to specifically explain the embodiments and should not be interpreted as being limited to those terms.

[0018] As shown in the three-dimensional view, plan view, and side view of FIGS. 1 to 3, which are preferred examples, and FIGS. 4, which is a three-dimensional view in FIGS. 1 with the fence removed to make the interior visible, the foldable pallet (1) for loading an object (100) is provided on the inner upper side of the lower base frame (2) to load and place the object (100), and the foldable fence (5) is provided on the outer upper side of the base frame (2) to protect the object (100) and to allow the pallet (1) to be placed on top when loading the object (100).

[0019] As seen in the exploded perspective view of FIG. 5, the base frame (2) of the present invention is provided with several supports (6), each comprising a pair of outer supports (6-1) configured to have a pair of fork coupling members (61) that penetrate inwardly and outwardly in a lateral direction so that a forklift fork is inserted while in contact with the floor from the bottom, and an inner support (6-2) configured to have a pair of fork coupling members (61) that penetrate inwardly and outwardly in a lateral direction in the center between the pair of outer supports (6-1); and several fixing members (7), each comprising a pair of outer fixing members (7-1) installed to fix a pair of fork guide members (71) that allow a forklift fork to be inserted downwardly on the upper part of the supports (6), and an inner fixing member (7-2) installed to fix the upper part of the supports (6) in the center between the pair of outer fixing members (7-1); and between the fixing members (7), that is, the outer fixing members (7-1) and Four pairs of lower support members (8) are provided, each pair installed at a predetermined interval between the inner fixing members (7-2) so that both ends are fixed to the fixing member (7) and a support member (81) is supported in the middle, so that when a loading object (100) is loaded, the lower support members (8) are supported.

[0020] The two-stage foldable supporter (4) of the present invention is installed to rotate so as to be folded in two stages with a height difference between the upper and lower parts of the inner upper part of the base frame (2), configured so as to allow a loading object (100) to be placed when rotated to stand upright vertically, and configured so as to flatten the volume in parallel with the base frame (2) when rotated to fold horizontally, and configured so as to allow the slewing motor and driving motor of an excavator to be loaded and placed on the upper and lower parts, respectively, with a loading object (100) of different size and shape depending on the type.

[0021] As shown in FIG. 6, this double-folding supporter (4) is installed such that its lower end is pivotally connected to a lower pivot coupling member (41) formed to protrude upwardly from the lower support member (8) of the base frame (2) so as to be erected vertically upward and folded horizontally downward. When erected, a lower mounting pad (46) having a non-slip function and a cushioning function is attached to the upper end, and a lower inner supporter (4-1) is configured to allow a relatively small loading object (100) to be loaded and placed on the upper end. The lower pivot coupling member (41) is connected to both ends of a pivot pin (44) that is connected through a fixing bracket (43) fixed to protrude upwardly in pairs from the lower support member (8), and the inner supporter (4-1) is fixedly installed on a pivot bracket (45) that is installed to rotate freely on the fixing bracket (43). As shown in FIG. 6, the above-described two-stage foldable supporter (4) is installed such that its lower end is pivotally connected to an upper pivot coupling member (42) formed to protrude upwardly on an upper support frame (3) which is fixedly installed on the upper part of the fixing bracket (7) of the base frame (2), so as to be upright vertically and folded horizontally downwards. When standing upright, an upper placement pad (47) having a non-slip and cushioning function is attached to the upper end, and an upper outer supporter (4-2) is provided so that a relatively large object to be loaded (100) is loaded and placed on the upper end. Since the upper pivot coupling member (42) is connected to both ends of a pivot pin (44) that penetrates and is connected to a fixing bracket (43) fixed to protrude upwardly in pairs on the upper support frame (3), and the outer supporter (4-2) is fixedly installed on a pivot bracket (45) that is installed to rotate freely on the fixing bracket (43), the lower pivot coupling member (41) and the upper pivot coupling member (42) are identical. The lower pivoting member (41) and the upper pivoting member (42) can be configured to be vertically erected by rotating the inner supporter (4-1) and the outer supporter (4-2) respectively around the pivoting pin (44), and horizontally folded toward the lower support member (8) and the upper support frame (3) of the base frame (2) by rotating downward.

[0022] At this time, the inner stopper (10) is fixed so that the inner supporter (4-1) rotating on the base frame (2) is fixed when standing vertically, and the outer stopper (20) is fixed so that the outer supporter (4-2) rotating on the upper support frame (3) is fixed when standing vertically.

[0023] The inner stopper (10) is composed of an inner rotation catch (11) installed so as to be rotatable on the outer side of the inner supporter (4-1) to rotate so that when the inner supporter (4-1) rotates upward on the upper part of the lower support member (8) of the base frame (2) to stand up, the inner supporter (4-1) does not rotate downward and maintain an upright state without folding, and an inner fixing catch (12) fixedly installed on the side of the lower support member (8) to engage with the inner rotation catch (11), and an outer rotation catch (21) installed so as to be rotatable on the outer side of the outer supporter (4-2) to rotate so that when the outer supporter (4-2) rotates upward on the upper part of the upper support frame (3) to stand up, the outer supporter (4-2) does not rotate downward and maintain an upright state without folding, and an outer rotation catch (21) to engage with the outer rotation catch (21). It consists of an outer fixing latch (22) fixedly installed on the side of the upper support frame (3).

[0024] A fixed support bar (4-3) exists in the inner supporter (4-1) and outer supporter (4-2), and a variable support bar (4-4) exists in some of the inner supporter (4-1). The fixed support bar (4-3) is formed to protrude to both sides of the lower support pad (46) and upper support pad (47) attached to the upper parts of the inner supporter (4-1) and outer supporter (4-2), so as to prevent the load object (100) loaded on the lower support pad (46) and upper support pad (47) from being detached from the upper part of the inner supporter (4-1) and outer supporter (4-2). The variable support bar (4-4) is configured such that one of the fixed support bars (4-3) on both sides of the upper part of some of the inner supporter (4-1) is separated from and connected to the inner supporter (4-1). It is configured to be separated from the inner supporter (4-1) so as to be fitted into a plurality of connecting holes (4-5) formed along the length on one side of the upper part of the inner supporter (4-1) so as to be adjustable according to the horizontal size change of the object (100) loaded on the upper part of the inner supporter (4-1).

[0025] The variable support bar (4-4), separated from the above-mentioned coupling hole (4-5), is connected to the inner supporter (4-1) and the connecting means (4-6) to prevent loss. The connecting means (4-6) is composed of a chain or wire, with both ends connected to one side of the inner supporter (4-1) and one side of the variable support bar (4-4). In addition, a protective cap (4-7) is attached to the upper ends of the fixed support bar (4-3) and the variable support bar (4-4) so ​​that when a loading object (100) is loaded onto the fixed support bar (4-3) and the variable support bar (4-4), they can be configured to be spaced apart from each other while preventing impact.

[0026] In the present invention described above, the two-stage folding fence (5) is installed so as to be fixed upright on the upper outer side of the fixing member (7) on the base frame (2), with a height difference between the upper and lower two-stage fences (5-1) and the upper fences (5-2) facing each other at orthogonal positions, and is configured to prevent the load object (100) placed on the two-stage folding supporter (4) from escaping to the outside when rotated to be vertically upright, and is configured to flatten the volume to be parallel with the base frame (2) when rotated to be folded horizontally.

[0027] The above-mentioned two-stage folding fence (5) is rotated upward and, when standing upright, a pair of lower fences (5-1) and a pair of upper fences (5-2) facing each other at the four corners of the top are individually fixed adjacently by a fastener (9), so that a separate pallet (1) is placed on the upper side.

[0028] In the present invention, when the two-stage folding fence (5) is folded in two stages, several spaced fixed supports (51) having a predetermined height are configured to stand upright on the outer upper side of the base frame (2), that is, on the support (6) of the base frame (2), so that they are positioned above the two-stage folding supporter (4) that is folded in two stages on the inner lower side of the two-stage folding fence (5).

[0029] The foldable pallet (1) for loading excavator motors according to the present invention, configured as described above, has a two-stage foldable supporter (4) installed on the inner side of the lower base frame (2), and a two-stage foldable fence (5) that folds on the upper side of the two-stage foldable supporter (4) which is folded by a spaced fixed supporter (51) on the outer side of the base frame (2). As shown in FIGS. 1 to 6, when the inner supporter (4-1) is vertically erected so as to rotate on the upper side of the base frame (2), it is possible to load and place two 25-ton slewing motors and two 25-ton driving motors of an excavator, or four 25-ton slewing motors and four 25-ton driving motors of an excavator as the loading object (100).

[0030] At this time, the inner supporter (4-1) is fixed by an inner stopper (10) in which an inner rotational latch (11) installed on the outer side of the inner supporter (4-1) is engaged and fixed with an inner fixing latch (12) fixed to a fixing bracket (7) of the base frame (2) so that the inner supporter (4-1) is not arbitrarily folded horizontally when standing upright, and the lower placement pad (46) on the upper side of the inner supporter (4-1), the fixing support bar (4-3) protruding upward on both sides of the upper side of the inner supporter (4-1), and the protective cap (4-7) attached to the upper side of the fixing support bar (4-3) can be used to stably load and place the object to be loaded (100).

[0031] As shown in FIGS. 1 to 6 above, when the two-stage foldable supporter (4) and the two-stage foldable fence (5) are in an upwardly upright state on the base frame (2), and the inner supporter (4-1) is folded to the base frame (2) as shown in FIGS. 7 to 9, only the outer supporter (4-2) is in an upwardly upright state on the upper support frame (3) located diagonally opposite the base frame (2), so that two 30-ton swing motors, which are larger in size than the 25-ton travel and swing motors of the excavator, can be loaded and placed in a diagonal position inside the pallet (1) as a loading object (100). The outer supporter (4-2) is also fixed by an outer stopper (20) in which the outer rotation catch (21) is caught and fixed to the outer fixing catch (22) fixed to the upper support frame (3) when the outer supporter (4-2) is upright, so that the upper part of the outer supporter (4-2) The object to be loaded (100) can be stably loaded by means of a protective cap (4-7) coupled to the top of the fixed support bar (4-3) and variable support bar (4-4) that protrude upward on both sides of the upper mounting pad (47) and the outer supporter (4-2).

[0032] In addition, as shown in FIGS. 10 and 11, a pair of inner supporters (4-1) located diagonally inside the pallet (1) are folded downward to the base frame (2), and a pair of outer supporters (4-2) located diagonally are folded downward to the upper support frame (3). Then, a pair of inner supporters (4-1) located diagonally opposite to the outside, where no outer supporter (4-2) exists, are unfolded and placed in an upright position. This allows two 30-ton driving motors, which are larger than the 25-ton driving and swinging motors of an excavator and smaller than the 30-ton swinging motor, to be loaded and placed diagonally inside the pallet (1) as the loading object (100). This is achieved by using a plurality of fixed support bars (4-3) formed along the length on the upper side of the inner supporter (4-1) instead of the fixed support bar (4-3) on one of the upper sides of the inner supporter (4-1). A variable support bar (4-4) that is fitted into a coupling hole (4-5) is fitted into an outer coupling hole (4-5) to load and place an object (100). At this time, as shown in FIGS. 1 to 6, when a 25-ton driving motor or a slewing motor is loaded and placed on four pairs of inner supporters (4-1) of a pallet (1), the variable support bar (4-4) is fitted into an inner coupling hole (4-5) so that the object (100) can be stably supported and loaded by the fixed support bar (4-3) and the variable support bar (4-4).

[0033] This also allows the object to be loaded (100) to be loaded more stably by means of the inner stopper (10), which is formed such that when the inner supporter (4-1) stands up, the inner rotational catch (11) is secured by the inner fixing catch (12) fixed to the base frame (2), and the lower mounting pad (46) on the top of the inner supporter (4-1) and the protective cap (4-7) coupled to the upper parts of the fixed support bar (4-3) and variable support bar (4-4) protruding upward on both sides of the upper part of the inner supporter (4-1).

[0034] As shown in FIGS. 1 to 11 above, various sizes and types of objects to be loaded (100) are loaded and placed to be transported to a required location. At this time, a pair of lower fences (5-1) and a pair of upper fences (5-2) facing each other are connected and fixed by a fastener (9) at the adjacent upper end, so that the pallets (1) loaded with objects (100) are stacked in multiple layers on the upper side of the pallets (1) loaded with objects (100) so that a large quantity can be transported at once.

[0035] In order to minimize the volume of the pallet (1) and recover a large quantity at once after loading and transporting the object (100) as shown in FIGS. 12 to 14, since there is no object (100) on the pallet (1), the inner supporter (4-1) and outer supporter (4-2), which are the inner two-stage folding supporters (4), are rotated downward and folded to the base frame (2) and the upper support frame (3), respectively.

[0036] In addition, the fasteners (9) fitted and coupled to each upper corner of the double-folding fence (5) are separated, and then, as shown in FIGS. 15 to 17, a pair of lower fences (5-1) facing each other among the double-folding fences (5) installed on the upper part of the spaced fixed supporter (51) which is fixed upright on the edge of the base frame (2) while the double-folding supporter (4) is folded are rotated downward to be folded on the upper side of the double-folding supporter (4), and as shown in FIGS. 18 to 20, a pair of upper fences (5-2) facing each other among the double-folding fences (5) are rotated downward toward the folded lower fences (5-1) to be folded, thereby minimizing the total volume of the pallet (1) so that a maximum amount can be loaded into a container, etc., and transported by ship, etc., thereby minimizing logistics costs, and the double-folding supporter (4) and By implementing the double-folding fence (5) as a foldable unit, convenience of use can be enhanced, and various benefits can be achieved, such as significantly reducing manufacturing costs with a simple configuration.
