Description

Technical Field

[0001] The invention belongs to the field of wheelset packaging racks, and in particular relates to a sea-borne packaging rack for truck wheelsets. Background Art

[0002] With the current increase in shipping container fees, it is becoming increasingly urgent to maximize the use of container space to ship more cargo. The length, width and height dimensions of a 20-foot container are 5898×2352×2385mm. For ordinary truck wheelsets, the wheel diameter is φ840mm and the axle length is over 2500mm. Due to the size limitations of the container, the wheel diameter of one wheel is 840mm. If three wheels are closely arranged side by side, the size will reach over 2500mm. The same applies to the height direction. Generally, the wheelsets are staggered for packaging. However, considering the convenience of forklift transportation, only two layers can be stacked in the height direction. A container with two sets can only hold 12 wheelsets, resulting in a serious weight loss and a surge in shipping costs. If it is designed to be three-layered, the height will be too high to enter the container. If the forklift opening is eliminated to meet the height requirements, ordinary containers cannot be used.

[0003] Utility model patent publication number CN202743673U, published on February 20, 2013, discloses a wheelset packaging rack. This rack consists of two rectangular frames, each formed by four longitudinal crossbars and four widthwise crossbars. The two rectangular frames are connected by support rods and connected to four vertical poles at their height. Diagonal braces are installed between the rectangular frames and the vertical poles. Reinforcement ribs are added to the bottom of the rectangular frames, and supports are placed above the rectangular frames. The supports have bolts for securing fastening straps. This wheelset packaging rack also fails to address the aforementioned technical issues. Summary of the Invention

[0022] The following is a further detailed description of the specific implementation methods of the present invention through the description of the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0023] like Figure 1 As shown, the sea transport packaging rack of the truck wheelset includes a base 1, a support frame 2 is provided on both sides of the base 1, the support frame 2 includes a first support rod 21 and a second support rod 22, and support plates are provided on the first support rod 21 and the second support rod 22. The support plates include a first support plate 3, a second support plate 4 and a third support plate 5. The first support plate 3 is located at the bottom of the support frame 2, the second support plate 4 is located above the first support plate 3, and the third support plate 5 is located at the top of the second support rod 22.

[0024] The sea-carrying packaging rack of the truck wheelset adopts a frame structure as a whole. The support frame 2 provides a setting position for the support plate. The first support plate 3, the second support plate 4 and the third support plate 5 serve as the lower, middle and upper support areas of the wheelset respectively. The middle support part is a detachable support plate, which is convenient for disassembly and shipment of the lower wheelset. A set of limit blocks 6 are welded on the support plate to support and position the wheelset. A rectangular tube forklift opening 13 is designed at the bottom to facilitate forklift transportation during packing. A longitudinal beam 12 is designed on the side to improve the overall strength and facilitate transportation from the side by a forklift within the factory. Because of the design of the bottom forklift opening 13, the overall height of the wheelset needs to be further reduced. The wheels 72 are staggered at three ends in the axial direction and are also staggered in three layers in the height direction. However, in order to reduce the height, two wheelsets are placed on the third layer and the two wheelsets are close to the middle to reuse the gap between the wheelsets to reduce the overall height.

[0025] like Figure 1 As shown, the second support rod 22 is higher than the first support rod 21. The first support rod 21 is located at both ends of the base 1, and the second support rod 22 is located between the first support rod 21. The first support plate 3 at both ends of the support frame 2 is fixedly connected to the first support rod 21 and the second support rod 22 at both ends, respectively. The first support plate 3 located in the middle of the support frame 2 is fixedly connected to the second support rod 22. The lower and middle support plates are arranged in parallel. The second support rod 22 is longer, and its top serves as the support area for the upper wheelset. The upper support plate is located between the lower and middle support plates in the height direction. After the wheelset is placed, it is staggered in the height direction, thereby reducing the overall height, reducing the volume of the overall packaging rack within the container, and increasing the loading capacity.

[0026] like Figures 1 to 4 As shown, support ribs 42 are provided on the inner side of the top of the first support rod 21 and on both sides of the second support plate 4. A limiting plate 41 is provided at the bottom of the second support plate 4. The limiting plate 41 and the second support plate 4 form a T-shaped structure. The support ribs 42 and the top of the first support rod 21 are provided with grooves 43, and the ends of the limiting plate 41 are located in the grooves 43. The second support plate 4 is not fixedly connected to the first support rod 21 or the second support rod 22. The ends of the limiting plates 41 are inserted into the grooves 43 to cooperate and support and fix the second support plate 4. The above structure realizes the detachable effect of the second support plate 4, so that the wheelsets of the lower and middle layers are arranged coplanar in the height direction, which is conducive to reducing the width of the overall packaging rack, reducing the space occupied in the container, and thus increasing the loading capacity. When placing the wheelsets of the lower layer, only the second support plate 4 needs to be removed to form space for the wheelsets of the lower layer. When the lifting mechanism lifts the wheelsets, the placement of the wheelsets of the lower and middle layers does not require two positioning, which can simplify the operation process and improve packaging efficiency.

[0027] like Figure 1As shown, the support plate is provided with stoppers 6, which are arranged opposite each other and have a triangular structure. The stoppers 6 are welded symmetrically along the central axis of the support plate. A certain space is left between the two sets of stoppers 6 to form a V-shaped groove for supporting and securing the wheelset. The wheel axle 71 is placed in this position to prevent rolling on the support plate, further improving the stability of the wheelset. The stoppers 6 are angle steel, which facilitates welding and fixing to the support plate.

[0028] like Figures 1 to 3 As shown, a forklift opening 13 is provided at the bottom of the base 1. Two sets of crossbeams 11 and longitudinal beams 12 are placed upright and welded to form a rectangular frame structure as the base 1 of the entire packaging rack. Four forklift openings 13 are welded at the contact point between the crossbeams 11 and longitudinal beams 12 and at the bottom of the crossbeam 11 as forklift transportation points. The base 1 is designed with four forklift openings 13 to facilitate forklift transportation of the entire unit.

[0029] like Figure 1 As shown, a third support rod 31 is fixedly connected between the middle of the first support plate 3 and the base 1. A reinforcing rib 51 is provided at the bottom of the third support plate 5. To further enhance the supporting performance of the first support plate 3, the third support rod 31 is provided between its bottom and the base 1. This transfers the forces acting on the first support plate 3 along the third support rod 31 to the base 1, preventing deformation of the first support plate 3 and improving durability. Since the third support plate 5 is not secured at either end by structural members, a reinforcing rib 51 is welded between its bottom and the third support rod 31 to enhance its structural strength.

[0030] like Figure 1 and Figure 3 As shown, the second support rods 22 on either side of the base 1 are fixedly connected to reinforcement rods 23. The reinforcement rods 23 are at the same height as the second support plate 4 and are located below the center of the third support plate 5. The reinforcement rods 23 connect the second support rods 22 on either side of the base 1, preventing deformation of the second support rods 22. Their coplanarity with the second support plate 4 further enhances the support performance of the second support plate 4. The reinforcement rods 23 also provide a wrapping area for the packaging strap 8 of the upper wheelset.

[0031] like Figure 1 As shown, the base 1 includes a crossbeam 11 and a longitudinal beam 12. The longitudinal beam 12 is located below the middle of the first support plate 3 and the second support plate 4. The crossbeam 11 is an I-beam, the longitudinal beam 12 is a channel steel, the first support rod 21, the second support rod 22 and the third support rod 31 are all square tubes, the support plate is a steel plate, and the limit block 6 is an angle steel.

[0032] like Figure 2 and Figure 3As shown, the wheelset includes an axle 71 and wheels 72. The axle 71 is mounted on a support plate, with stoppers 6 located on either side of the axle 71. The axle 71 and longitudinal beam 12 are wrapped with packing tape 8, and the wheels 72 of adjacent wheelsets are staggered. After the wheelset is placed on the support plate, the axle 71 and longitudinal beam 12 are tightened and secured with packing tape 8 to improve stability. Furthermore, the wheels 72 of adjacent wheelsets are staggered not only axially but also in height, further reducing the space occupied and thereby lowering the overall height of the packaging rack.

[0033] The sea-transport packaging rack for the truck wheelset has two left and right groups of support plates on the lower layer and a middle support plate that welds the first support rod 21 and the second support rod 22 into a whole, and the whole is symmetrically arranged along the middle part of the longitudinal beam 12; wherein, the middle support plate is a detachable structure, the upper part is two groups of limit blocks 6 arranged in a mirror image, and the lower layer is a vertically welded limit plate 41 used to improve the overall strength. After disassembly, the gap can be left to place the wheelset in the lower layer; two groups of support ribs 42 are welded on the inner side of the top of the left and right first support rods 21, and two groups of support ribs 42 are welded on the left and right sides of the second support rod 22 at the same height, and the support ribs 42 are used to support the second support plate 4; a third support plate 5 is welded on the top of the second support rod 22, and similarly, two angle steels are welded symmetrically along the midpoint of the third support plate 5 to support and fix the wheelset.

[0034] When in use, place the packaging rack flat on the ground, remove the second support plate 4, and place the wheel pairs on both sides on the first support plates 3 on both sides of the lower layer and make the wheel axle 71 located in the V-groove formed by the limit block 6 to ensure that the wheel pair is in the same plane with the longitudinal beam 12. Similarly, place the wheel pair on the first support plate 3 in the middle of the lower layer. After the three sets of wheel pairs on the lower layer are placed, snap the second support plate 4 into the corresponding support rib 42, and place the wheel pair on the second support plate 4 again and fix it. The wheels on both sides of the wheel pair are staggered 5 to 10 mm forward from the two lower wheel pairs, and the middle wheel pair is staggered 20 to 30 mm backward; finally, place the two wheel pairs on the upper layer on the left and right third support plates 5 respectively and pack and fix them. When placing, stuff the wheel pairs into the staggered gap between the lower and middle wheel pairs.

[0035] The sea-transportation packaging rack for truck wheelsets realizes the staggered distribution of the wheels 72 of the wheelsets in the axial and height directions by rationally designing the packaging rack frame structure and the wheelset support parts, thereby reducing the overall height of the packaging rack and reducing the width of the packaging rack, avoiding the situation where the designed height is too high and the cargo cannot be loaded into the container. There is no need to cancel the design of the forklift opening 13, which facilitates the transfer and transportation of the packaging rack, improves the space utilization rate in the container, increases the loading number of wheelsets, and reduces the sea transportation cost; and the second support plate 4 is designed to be detachable, which also facilitates the placement of the wheelsets in the lower layer and improves the packaging efficiency; the overall structure of the packaging rack is simple, the connection effect is reliable, and the manufacturing cost is low.

[0036] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described method. Any non-substantial improvements made using the method concepts and technical solutions of the present invention, or any direct application of the above-described concepts and technical solutions to other situations without modification, fall within the scope of protection of the present invention.
