Description

Technical Field

[0001] The present invention relates to the technical field of logistics and transportation, and in particular to a mobile cargo transport rack for logistics. Background Art

[0002] In the field of modern logistics, with the booming development of the e-commerce industry, the continuous expansion of the manufacturing industry and the increasing complexity of the supply chain system, the demand for efficient, flexible and reliable logistics equipment in the cargo transportation and warehousing links has become more urgent. Traditional cargo transport racks have gradually exposed their shortcomings in many aspects and are unable to meet the current logistics operation requirements.

[0003] On the one hand, the storage structure of conventional transport racks is mostly fixed, and the spacing between the storage boards is difficult to change once it is set. However, the types of goods handled in logistics practice are diverse and the size range is extremely large, ranging from small electronic components and precision instruments to large mechanical parts and industrial molds. The fixed-spacing storage boards often lead to either wasted space, which makes it impossible to fully utilize the three-dimensional volume of the transport rack, or it is difficult to place certain special-sized goods due to space limitations, which seriously restricts the efficiency of storage and transportation and increases unnecessary logistics costs.

[0004] On the other hand, in terms of adaptability to transportation scenarios, the bottom of traditional transport racks is usually only equipped with a single type of wheel, which is usually a regular directional wheel or a small universal wheel. In an ideal environment such as a flat and barrier-free warehouse, it can basically meet the needs of short-distance movement and transportation; but once faced with complex and changeable road conditions outside the warehouse, such as temporary passages full of stones, outdoor loading and unloading areas with uneven ground, etc., these wheels are unable to cope with the situation. Due to poor passability, not only is there huge resistance and a lot of manpower consumed when pushing, but it is also very easy to cause the transport rack to shake, causing the goods to slip and collide and be damaged, posing a great hidden danger to the safe transportation of goods. Summary of the invention

[0005] The object of the present invention is to provide a mobile cargo transport rack for logistics to solve the problems raised in the background technology.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0028] like Figure 1-Figure 9 As shown, the present invention proposes a kind of logistics cargo transport rack which is easy to move. The present invention comprises a transport main frame 1, and the four corners of the bottom thereof are equipped with heavy-duty casters 3. At the same time, two sets of fixing plates 105 are also arranged at the bottom. A rotating shaft 107 is flexibly installed between each set of fixing plates 105 by means of a bearing seat 106. Wheel fixing plates 108 are symmetrically welded at both ends of the rotating shaft 107. The rotating shaft 107 is specially designed to be adapted to the installation of spare wheels under special road conditions. When encountering gravel roads and uneven sections, a large-size spare wheel can be conveniently replaced to enhance the passability.

[0029] A pair of opening and closing doors 104 are installed on the front of the transport main frame 1, and a pair of push handles 102 are firmly placed on the right outer wall. Several pairs of movable slideways 100 are opened on the inner walls of both sides of the transport main frame 1, and built-in slide rails 101 are opened. A pair of guide grooves 103 are symmetrically opened on the left and right side walls, distributed on the outside of the array of movable slideways 100, for placing the screw rods 606 of the storage plate 600, and cooperating with the nuts 607 to stabilize the vertical position of the storage plate 600 and assist in adjusting the spacing;

[0030] Several adjustable storage components 6 are arranged in the transport main frame 1. The adjustable storage components 6 are mainly composed of a storage plate 600. Two pairs of sliders 601 are symmetrically welded on both sides of the storage plate 600. Pull rings 602 are welded on the top of the sliders 601 as force connection points. In cooperation with them, a pair of small rope collection traction machines 603 are installed at the corresponding positions on the top of the transport main frame 1. Each traction machine is equipped with two sets of steel ropes 604. The steel ropes 604 are wound around the guide pulley 4 and introduced into the moving slideway 100 through the threading hole 109. The ends of the steel ropes 604 are connected to the hooks 605 and tightly fastened to the pull rings 602, so that the horizontal position of the storage plate 600 can be accurately adjusted by the traction machine to retract and release the steel ropes 604, and the spacing between the storage plates 600 can be flexibly changed.

[0031] A pair of power supply control modules 2 are installed on the top of the transport main frame 1, which are responsible for providing power to the array of small rope collection traction machines 603 and realizing precise electronic control connection to ensure the operation of each traction machine. In addition, the inner bottom plate of the transport main frame 1 is provided with anti-slip grooves 5, and the top of the storage plate 600 is also provided with anti-slip grooves 7, which effectively increase the friction between the goods and the contact surface, prevent the goods from accidentally sliding and shifting during transportation, and ensure the safe and stable transportation of goods.

[0032] When in use, the spacing between the storage plates 600 needs to be adjusted. First, find the corresponding screws 606 on the storage rack, and use the adapter tool to loosen the nuts 607 one by one. The strength needs to be controlled during the loosening process to ensure that the nuts 607 can be loosened so that the storage plates 600 are free from the tightening restrictions and have adjustable conditions. When all the relevant nuts 607 are loosened in place, the next step can be performed.

[0033] The two small rope-collecting traction machines 603 corresponding to each storage board 600 are turned on. According to the direction of adjustment required, if the spacing of the storage boards 600 is to be increased, the traction machines are synchronously controlled to unwind the ropes, and the ropes are gradually released. The storage boards 600 rely on the slider 601 and slide smoothly outward along the slide rail 101. On the contrary, if the spacing is to be reduced, the traction machine rewinding operation is started at the same time, and the storage boards 600 are pulled to slide inward on the slide rail 101 by rope traction. During the entire adjustment process, attention should be paid to the movement of each storage board 600 at all times to ensure smooth and synchronous movement and prevent abnormal conditions such as jamming and skewing. After all storage boards 600 are accurately adjusted to the expected spacing, carefully check again whether the positions of each storage board 600 are stable and flush. After confirmation, re-tighten several nuts 607, and then the storage boards 600 can be layered according to their heights, and the corresponding goods can be placed in the corresponding storage layers in an orderly manner.

[0034] In places like warehouses where the ground is flat, the friction is uniform and there are few obstacles, the heavy-duty casters 3 at the bottom of the device can play an excellent maneuverability. When pushing, the operator only needs to hold the device handle tightly and apply force to control the direction. With the flexible steering and stable support of the heavy-duty casters 3, the device can be easily driven to move along the predetermined route, completing short-distance transportation and shifting work efficiently and conveniently.

[0035] However, when facing gravel sections or uneven roads, the heavy-duty casters 3 have a relatively small wheel diameter and limited passability, so the pushing resistance increases dramatically and is prone to bumps and shakes, and the stability is greatly reduced. At this time, it is necessary to replace the wheels to adapt to the road conditions, take out the spare wheels, align the installation positions of the wheel fixing plates 108 on both sides of the device, and install the spare wheels steadily and accurately to ensure that they are installed firmly and tightly without any signs of looseness. With the larger wheel diameter and wide tread of the spare wheels, in the subsequent pushing process, it can cross gravel and potholes more smoothly, effectively buffer road bumps, and allow the device to maintain a stable forward state, ensuring safe and efficient cargo transportation.

[0036] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
