[0027] Embodiment 1

[0028] This embodiment provides as Figures 1 to 6The container pallet for airport cargo transportation shown in the figure comprises a main frame 1, the main frame 1 comprises a horizontally arranged bottom plate 11, four corners of the bottom plate 11 are provided with notches 12, a top plate 13 is horizontally arranged above the bottom plate 11, and a support assembly 14 is arranged between the top plate 13 and the bottom plate 11;

[0029] Electric push rods 2 are vertically provided at the four corners of the main frame 1. The electric push rods 2 include an inner rod 21 and an outer rod 22. The inner rod 21 vertically passes through the top plate 13 and the notch 12 in sequence and is fixedly connected to the universal wheel 3. The outer rod 22 is located above the top plate 13, and a flange 23 is fixedly sleeved at the lower end of the outer rod 22. The flange 23 is fixed to the corners of the upper surface of the top plate 13 by bolts. A universal wheel 3 is provided at the lower end of the electric push rod 2.

[0030] By cooperating with the universal wheels 3, the electric push rod 2 can be used to make the wheels fully extend out of the main frame 1 or other suitable sizes during ground transportation by utilizing the high-precision controllable telescopic function of the electric push rod 2, thereby ensuring the passability of the wheels. The electric push rod 2 uses servo electric cylinder technology to control the telescopic height of the four universal wheels 3.

[0031] When the container pallet as a whole needs to be loaded and unloaded and transported to the rear of the cabin, the electric push rod 2 can control the universal wheel 3 to retract from the notch 12 of the bottom plate 11 into the subject frame, so that the bottom plate 11 of the bottom plate 11 can fully contact the cabin roller shaft, so that it can be transported into the cabin by rolling.

[0032] Furthermore, a fence 4 is provided between two adjacent outer rods 22 . The fence 4 includes a horizontally arranged crossbar 41 . A plurality of vertical upright rods 42 are fixedly connected to the bottom of the crossbar 41 . The lower ends of the upright rods 42 are fixed to the upper surface of the top plate 13 .

[0033] The fence 4 can provide a position limiting protection for the goods placed on the top plate 13, thereby preventing the goods from falling off the top plate 13 during loading and unloading.

[0034] Furthermore, the support assembly 14 includes a plurality of vertically arranged support rods 141, wherein the plurality of support rods 141 are located between the top plate 13 and the bottom plate 11, and the plurality of support rods 141 are arranged in three rows at intervals, each row having three support rods 141, and the top plate 13 and the bottom plate 11 are fixedly connected by the support rods 141, and connecting rods 142 are horizontally provided at the upper and lower ends of the support rods 141, and the two ends of the connecting rod 142 are respectively fixedly connected to two adjacent support rods 141.

[0035] By cooperating with the support rod 141 and the connecting rod 142 in the support assembly 14 , the top plate 13 and the bottom plate 11 can be fixedly supported, thereby ensuring the overall stability of the main frame 1 .

[0036] Further, two fixing rods 5 are vertically arranged at the left side between the bottom plate 11 and the top plate 13. Both ends of the fixing rod 5 are fixedly connected to the top plate 13 and the bottom plate 11 respectively. A horizontally arranged traction rod 6 is hinged on the fixing rod 5.

[0037] Through the provided traction rod 6, the function of towing can be achieved by means of vehicle or manual traction, thus facilitating the use by the staff. Among them, by setting the traction rod 6 into two, a traction point can be added, thereby improving the stability during traction. And the free ends of the two traction rods 6 can be rotated together through the hinge ends, and then the free ends of the two traction rods 6 are overlapped together for traction, so that the free and hinge ends of the two traction rods 6 form a triangular support, thereby further improving the stability during traction.

[0038] Further, a horizontally arranged folding ramp 7 is hinged to the right side of the bottom plate 11. Among them, the hinging mode of the folding ramp 7 is similar to the hinge hinging mode. When loading and unloading the container pallet onto and from the cabin, first open the folding ramp 7 to make the folding ramp 7 contact with the rollers on the airport. Two ramp supports 8 are provided on the folding ramp 7. The ramp supports 8 are rotatably connected between the top plate 13 and the bottom plate 11. The ramp supports 8 can play a role in limiting and fixing the folding ramp 7 to prevent the folding ramp 7 from being folded back under force. Among them, the ramp supports 8 are installed on the support rod 141 of the main body frame 1 through pins, and the ramp supports 8 and the support rod 141 do not interfere with each other.

[0039] Further, a hook 9 is provided between the two ramp supports 8. The hook 9 is fixed on the support rod 141. An opening 10 matching the hook 9 is provided at the position corresponding to the hook 9 on the folding ramp 7.

[0040] By cooperating the provided hook 9 with the traction rod 6, it can tow another container pallet, thereby realizing the series towing of multiple container pallets, so as to improve the efficiency of loading and unloading and transportation.

[0041] In use, the staff first move by controlling the towing bar 6, so that the towing bar 6 drives the top plate 13 and the bottom plate 11 of the main frame 1 to move together through the fixed bar 5. The top plate 13 then drives the electric push rod 2 to move on the ground through the universal wheels 3 below, so as to move the entire container pallet from the ground to a suitable position at the tail of the cabin, making the rear end of the advancing direction of the container pallet, that is, the end with the folding ramp 7, face the cabin tail. After reaching the cabin tail, the towing bar 6 is folded through the hinge joint with the fixed bar 5 to retract the towing bar 6 into the main frame 1. Then, the electric push rod 2 is controlled to extend to lift the entire container pallet, so that the bottom surface of the bottom plate 11 in the main frame 1 is 5 - 10 cm above the roller plane of the cabin. Then, the folding ramp 7 and the ramp support 8 are opened, and the entire main frame 1 is moved about 20 cm into the cabin. Then, it is controlled to drop so that the bottom surface of the bottom plate 11 presses on the cabin rollers. Then, the rear wheels of the container pallet are retracted into the main frame 1, and the container pallet is moved into the cabin by means of rolling using the cabin rollers. When most of the pallet enters the cabin, the front wheels of the container pallet are retracted into the main frame 1, and then the entire container pallet is continuously moved into the cabin by rolling until it completely enters the cabin. Then, the baffle is retracted to complete the loading, unloading and transportation of airport goods.

[0042] The utility model provides a container pallet for airport goods transportation, which can realize the loading and unloading of goods from the airport placement area to the transport aircraft cabin through its own various functions without the need for other equipment. It has a ground transportation function, is equipped with universal wheels 3 and a towing device, and can realize the towing function through vehicle or manual traction; it also has a self-loading and unloading function, and can realize the loading and unloading of goods from the ground to the height of the transport aircraft cabin through the extension and retraction of four electric push rods 2. At the same time, it has a roller loading function in the cabin to improve efficiency, thus solving the problems that the loading and unloading equipment of the container pallet is generally large in size, occupies more space, and has an overweight self-weight, resulting in too low cost performance for being carried into the cabin for transportation to other places. This makes the container pallet convenient to use and carry, no longer requires other types of supporting equipment to cooperate, and avoids the problem that it is difficult to realize the loading and unloading of the transport aircraft when going out to an airport without various equipment guarantees.
