Description

Technical Field

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

[0002] With the current increase in shipping container fees, it is becoming increasingly urgent to use container space to ship more goods. The length, width and height dimensions of a 20-foot container are 5898×2352×2385mm. For ordinary truck wheels, the wheel diameter is φ840mm and the axle length is more than 2500mm. Due to the size limit of the container, the wheel diameter of one wheel is 840mm. If three wheels are closely arranged side by side, the size will reach more than 2500mm. The same is true for the height direction. Generally, the wheels are staggered for packaging, but at the same time, the convenience of forklift transportation must be considered. Only two layers can be stacked in the height direction. A container with 2 groups can only hold 12 sets of wheels, resulting in serious weight loss and a surge in shipping costs. If it is designed as a three-layer container, it will be too high to enter the container. If the forklift port is cancelled to meet the height requirement, ordinary containers cannot be used.

[0003] The utility model patent with publication number CN202743673U was published on February 20, 2013. The packaging rack for wheelsets is composed of four longitudinal crossbars and four width crossbars, which respectively form two rectangular frames. The two rectangular frames are connected by support rods, and the two rectangular frames are respectively connected to four vertical poles in the height direction. Diagonal braces are arranged between the rectangular frames and the vertical poles, reinforcing ribs are added at the bottom of the rectangular frames, and supports are arranged on the rectangular frames; the supports have bolts for fixing the fastening belts.

DETAILED DESCRIPTION

[0022] The specific implementation methods of the present invention are further explained in detail below by describing 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 facilitating their implementation.

[0023] like Figure 1 As shown, the sea transport packaging rack of the truck wheel set includes a base 1, support frames 2 are provided on both sides of the base 1, the support frame 2 includes a first support rod 21 and a second support rod 22, 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 arranged at the top of the second support rod 22.

[0024] The sea transport 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 are respectively used as the lower, middle and upper support areas of the wheelset. The middle support part is a detachable support plate, which is convenient for disassembly and shipment of the lower wheelset. A group 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 forklift transportation from the side in the factory. Due to the design of the forklift opening 13 at the bottom, it is necessary to further reduce the overall height of the wheelset. The wheels 72 are staggered at three ends in the axial direction and 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 arranged at both ends of the base 1, and the second support rod 22 is arranged between the first support rod 21; the first support plate 3 located at both ends of the support frame 2 is respectively fixedly connected to the first support rod 21 and the second support rod 22 at both ends, and 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, and the second support rod 22 is longer, and its top is used as the support area of ​​the upper wheelset. The upper support plate is located between the lower support plate and the middle support plate 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 in the container, and increasing the loading capacity.

[0026] like Figures 1 to 4 As shown, a support rib 42 is provided on the inner side of the top of the first support rod 21 and on both sides of the second support plate 4, and a limit plate 41 is provided at the bottom of the second support plate 4. The limit plate 41 and the second support plate 4 are in a T-shaped structure. A groove 43 is provided at the support rib 42 and the top of the first support rod 21, and both ends of the limit plate 41 are located in the groove 43. The second support plate 4 is not fixedly connected to the first support rod 21 or the second support rod 22, and the end of the limit plate 41 is inserted into the groove 43 to cooperate to achieve the support and fixation of 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 layer and the middle layer are arranged in the same plane 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, it is only necessary to remove the second support plate 4, that is, to form a space for placing the wheelsets of the lower layer, and when the hoisting mechanism hoists the wheelsets, the placement of the wheelsets of the lower layer and the middle layer does not need to be positioned twice, which can simplify the operation process and improve the packaging efficiency.

[0027] like Figure 1As shown, the support plate is provided with limit blocks 6, which are arranged opposite to each other and are triangular in structure. The limit blocks 6 are symmetrically welded along the central axis plane of the support plate, and a certain position is left between the two groups of limit blocks 6 to form a V-shaped groove for supporting and fixing the placed wheelset. The wheel axle 71 is placed in this position to avoid rolling on the support plate, further improving the stability of the wheelset. The limit blocks 6 are angle steels, which are convenient for welding and fixing on 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 cross beams 11 and longitudinal beams 12 are placed upright and welded into a rectangular frame structure as the base 1 of the entire packaging rack. Four forklift openings 13 are welded at the contact position of the cross beam 11 and the longitudinal beam 12 and at the bottom of the cross beam 11 as forklift transportation points. The base 1 is designed with four forklift openings 13 to facilitate overall transportation by forklift.

[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, and a reinforcing rib 51 is provided at the bottom of the third support plate 5. In order to further improve the supporting performance of the first support plate 3, the third support rod 31 is provided between the bottom of the first support plate 3 and the base 1, so that the force of the first support plate 3 is transmitted to the base 1 along the third support rod 31, thereby avoiding deformation of the first support plate 3 and improving durability. Since there are no structural parts to fix the two ends of the third support plate 5, a reinforcing rib 51 is welded between the bottom of the third support plate 5 and the third support rod 31 to improve its structural strength.

[0030] like Figure 1 and Figure 3 As shown, the second support rods 22 on both sides of the base 1 are fixedly connected with reinforcing rods 23, the reinforcing rods 23 are at the same height as the second support plate 4, and the reinforcing rods 23 are located below the middle of the third support plate 5. The reinforcing rods 23 connect the second support rods 22 on both sides of the base 1 to avoid deformation of the second support rods 22, and they are coplanar with the second support plate 4, further improving the supporting performance of the second support plate 4. The reinforcing rods 23 can also provide a winding position for the packaging belt 8 of the upper wheelset.

[0031] like Figure 1 As shown, the base 1 includes a cross beam 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 cross beam 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 set on the support plate, the limit blocks 6 are located on both sides of the axle 71, the axle 71 and the longitudinal beam 12 are wrapped with a packing belt 8, and the wheels 72 of adjacent wheelsets are staggered. After the wheelset is placed on the support plate, the axle 71 and the longitudinal beam 12 are tightened and fixed with the packing belt 8 to improve stability. At the same time, the wheels 72 between adjacent wheelsets are not only staggered in the axial direction, but also in the height direction, which further reduces the occupied space, thereby achieving the effect of reducing the overall height of the packaging rack.

[0033] The sea transport packaging rack of the truck wheel set, the left and right groups of support plates in the lower layer and the middle support plate weld 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 layer 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, and the gap can be left after disassembly 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-shaped 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 in the lower layer are placed, snap the second support plate 4 into the corresponding support rib plate 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 placed forward of 5 to 10 mm corresponding to the two layers of wheel pairs in the lower layer, and the middle wheel pair is staggered backward of 20 to 30 mm; 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-going packaging rack for the truck wheelset realizes the staggered distribution of the wheels 72 of the wheelset in the axial and height directions by rationally designing the layout of 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, thus avoiding the situation where the designed height is too high and the goods cannot be loaded into the container. There is no need to cancel the design of the forklift opening 13, thus facilitating the transfer and transportation of the packaging rack, improving the space utilization rate in the container, increasing the loading quantity of the wheelset, and reducing the sea transportation cost. Furthermore, the second support plate 4 is designed to be detachable, which also facilitates the placement of the wheelset 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 is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
