[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] Embodiment 1, as Figure 1-3 As shown, a high-efficiency and energy-saving cold box stacker for cold chain logistics includes a mobile base 1, a rotating disk 3 is fixedly connected to the middle of the upper end of the mobile base 1, a lifting group 6 is fixedly connected to the output end of the rotating disk 3, a stacking mechanism 7 is provided in the middle of the lifting group 6, an intelligent control center 5 is fixedly connected to the middle of the right side of the upper end of the mobile base 1, an antenna 4 is provided at the front right side of the upper end of the mobile base 1, and anti-collision radars 2 are fixedly connected on all sides of the mobile base 1, the output end of the antenna 4 is electrically connected to the intelligent control center 5, and the output ends of the four anti-collision radars 2 are electrically connected to the intelligent control center 5 in common.

[0031] It should be noted that the specific installation methods and circuit connection methods and control methods of the anti-collision radar 2, antenna 4 and intelligent control center 5 in the present invention are all conventional designs, which are conventional design methods of designers. The anti-collision radar 2 and antenna 4 are connected to the intelligent control center 5 and used in conjunction with each other, wherein the antenna 4 plays a role in enhancing the signal strength. The intelligent control center 5 is composed of a signal receiver, a control center, a processor and a corresponding programming system, etc. The principle of the anti-collision radar 2 is similar to that of sonar, except that light is used instead of sound to measure the distance, a laser beam is emitted to the surroundings, and a rotating disk 3D model of the surrounding environment is drawn through the reflected signal. It has the advantages of high precision, high resolution and high sensitivity, and can provide accurate environmental perception information for unmanned driving. It is used in conjunction with the intelligent control center 5 to realize unmanned driving. The mobile base 1 is composed of a frame chassis, an energy-saving motor, wheels, new energy batteries, etc., which are used in conjunction with each other so that the mobile base 1 can drive the entire device to move while playing a role in energy saving. The rotating disk 3 and the excavator are used to realize the rotation function The slewing device is the same, consisting of a slewing support, a slewing motor and a central slewing joint, which can enable the lifting group 6 to rotate 360 ​​degrees infinitely relative to the mobile base 1. The slewing support is the core component of the excavator's slewing device. It connects the upper and lower system chassis. The slewing support is usually a large-diameter rolling bearing that can withstand huge axial and radial loads while allowing the upper system to rotate smoothly relative to the lower system; the slewing motor is the power source that drives the slewing support to rotate. It is usually a hydraulic motor driven by the pressure oil provided by the hydraulic pump. The slewing motor engages with the large gear ring of the slewing support through gears or chains, thereby transmitting the rotational power of the hydraulic motor to the slewing support to realize the rotation of the upper system; the central slewing joint is a key component for power transmission between the upper and lower frames of the excavator. It allows the hydraulic pipeline to remain connected when the device rotates without being torn or entangled due to rotation. The central slewing joint is designed with complex oil channels and seals to ensure that the oil can be smoothly transmitted between the upper and lower frames while preventing leakage.

[0032] Firstly, through the coordinated use of the anti-collision radar 2, the antenna 4 and the intelligent control center 5, the mobile base 1 can be unmanned, and in the coordinated use of the lifting group 6 and the stacking mechanism 7, the goods in the cold box can be efficiently loaded and unloaded from the ground or the transport vehicle, thereby reducing the labor intensity of manual handling and improving work efficiency. In the cold chain logistics warehouse, the goods can be stacked on shelves of different heights, or taken down from the shelves. In the limited space of the cold chain logistics warehouse, the lifting group 6 and the stacking mechanism 7 can be rotated at any angle by rotating the rotating disk 3. The goods can be placed directly on the symmetrical shelves of the device by only driving the lifting group 6 and the stacking mechanism 7 to rotate 180° through the rotating disk 3. There is no need to reverse or enter the vehicle, so that the goods can be quickly stored and retrieved, which makes the work more efficient and achieves high efficiency and energy saving as a whole.

[0033] In order to achieve the device can be adjusted in height, such as Figure 4 As shown, the lifting group 6 includes a connecting plate 61, and a left-right symmetrical supporting main frame 63 is provided in the middle of the upper end of the connecting plate 61, and a fixing plate 64 is fixedly connected to the lower part of the side away from each other of the two supporting main frames 63, and a front-back symmetrical hydraulic rod 65 is provided on the upper side of the end away from each other of the two fixing plates 64, and the output ends of the two hydraulic rods 65 on the same side are commonly fixedly connected to a supporting inner frame 66, and the inner cavities of the two supporting inner frames 66 are slidably connected with connecting parts 62, and the middle parts of the inner cavities of the two connecting parts 62 are fixedly connected with vertical plates 67, and the upper sides of the inner cavities of the two connecting parts 62 are provided with connecting shafts 68. The front ends of the two connecting shafts 68 respectively penetrate the inner cavities of the two connecting parts 62 and are fixedly connected with mounting plates 1 69, and the two mounting plates 1 69 are fixedly connected to the upper sides of the front ends of the two connecting parts 62 by bolts, and the front ends of the two 86 respectively penetrate the upper sides of the rear ends of the two vertical plates 67, and the middle part of the lower end of the connecting plate 61 is fixedly connected to the output end of the rotating disk 3, and the lower ends of the two connecting parts 62 are respectively fitted with the left and right sides of the upper end of the connecting plate 61.

[0034] It should be noted that the specific installation method of the hydraulic rod 65 , the circuit connection method and the control method in the present invention are all conventional designs, which are conventional design means of designers, and the hydraulic rod 65 is controlled by the intelligent control center 5 .

[0035] First, the intelligent control center 5 controls the hydraulic rods 65 on the left and right sides to drive the support inner frame 66 to slide upward in the inner cavity of the support main frame 63, and the movement of the support inner frame 66 drives the connecting component 62 to move upward, and finally drives the stacking mechanism 7 to move upward through the connecting component 62, so as to achieve the purpose of enabling the device to be adjusted in height. The left-right symmetrical design of the support main frame 63 increases the stability of the device when transporting goods. In addition, by removing the bolts of the mounting plate 69, the connecting shaft 68 can be pulled out of the connecting component 62 through the mounting plate 69, and the stacking mechanism 7 can be removed from the connecting component 62. Similarly, installation can also be achieved.

[0036] Embodiment 2: Based on Embodiment 1, this embodiment realizes the carrying or stacking of goods. Figure 5 As shown, the stacking mechanism 7 includes a fork 71, a moving group 73 is provided on the rear side of the lower end of the fork 71, a sensor 72 is provided in the middle of the front side of the moving group 73, and the left and right sides of the moving group 73 are fixedly connected with front and rear symmetrical mounting plates 74, and the inner cavities of the two mounting plates 74 on the same side are slidably connected to the front and rear sides of the outer surface of the connecting shaft 68 respectively.

[0037] It should be noted that the specific installation method of the sensor 72, the circuit connection method and the control method in the present invention are all conventional designs, which are conventional design means of designers, and the sensor 72 is controlled by the intelligent control center 5. Through the coordinated use of the sensor 72 and the intelligent control center 5, the distance between the goods and the mobile group 73 can be detected.

[0038] First, the stacking mechanism 7 is installed between the two connecting parts 62 through the installation plate 2 74 and the connecting shaft 68. When it is needed to work, the device is brought to the side of the goods by the cooperation of the mobile base 1 with the anti-collision radar 2, the antenna 4 and the intelligent control center 5. Then, the distance between the moving group 73, the fork 71 and the goods is detected by the sensor 72. Then, the fork 71 is slid forward by the moving group 73 to insert the fork 71 into the lower side of the goods. Then, the fork 71 is slid backward to transport the goods to the top of the moving group 73. When it is necessary to take out the goods at a high place, the moving group 73 is driven to a suitable height by the cooperation of the lifting group 6 and the sensor 72, and then the goods are taken out by the cooperation of the fork 71. When it is necessary to place the goods at a high place in the cold chain logistics warehouse, similarly, the moving group 73 is driven to a suitable height by the cooperation of the lifting group 6 and the sensor 72, and then the goods are placed on the shelves of the cold chain logistics warehouse by the fork 71. This is safer than operating under human observation.

[0039] Further explanation, such as Figure 6 and Figure 7 As shown, the moving group 73 includes a bottom plate 732, and a mounting groove 731 is provided in the middle of the left and right ends of the bottom plate 732, and a left-right symmetrical sliding groove 733 is provided in the middle of the upper end of the bottom plate 732. The inner cavities of the two sliding grooves 733 are fixedly connected with sliding rods 739, and the outer surfaces of the two sliding rods 739 are slidably connected with T-shaped sliders 734. The outer surfaces of the two T-shaped sliders 734 are respectively slidably connected with the inner cavities of the two sliding grooves 733, and the inner cavities of the two sliding grooves 733 are rotatably connected with front-to-back symmetrical rotating card wheels 738. The outer surfaces of the two rotating card wheels 738 on the same side are meshed and connected with a traction chain 735. The upper front sides of the two sides close to each other are respectively fixedly connected with the sides of the two T-shaped sliders 734 that are away from each other, and are located in the right sliding groove. A motor 736 is fixedly connected to the rear side of the inner cavity 733, and a rotating wheel 737 is fixedly connected to the output end of the motor 736 and the right end of the rotating card wheel 738 located at the rear right side. The two rotating wheels 737 are connected by belts, and the inner cavities of the two mounting grooves 731 are slidingly connected to the lower sides of the outer surfaces of the two vertical plates 67 respectively. The middle part of the front end of the bottom plate 732 is fixedly connected to the rear end of the sensor 72, the lower sides of the right ends of the two mounting plates 2 74 located on the left are fixedly connected to the left end of the bottom plate 732, and the lower sides of the left ends of the two mounting plates 2 74 located on the right are fixedly connected to the right end of the bottom plate 732. The opposite surfaces of the two rotating card wheels 738 located on the rear side are fixedly connected by a rotating shaft, and the upper ends of the two T-shaped sliders 734 are fixedly connected to the rear side of the lower end of the fork 71.

[0040] It should be noted that the specific installation method of the motor 736, the circuit connection method and the control method in the present invention are all conventional designs, which are conventional design means of designers, and the motor 736 is controlled by the intelligent control center 5.

[0041] In detail, the bottom plate 732 is installed between the two connecting parts 62 by clamping the mounting groove 731 on the lower side of the vertical plate 67, and the bottom plate 732 is installed between the two connecting parts 62 by cooperating with the connecting shaft 68 and the mounting plate 2 74 and the mounting plate 1 69 and the bolts. When the goods need to be taken out by the fork 71, the motor 1 736 is controlled by the intelligent control center 5 to drive the rotating wheel 737 fixedly connected thereto to rotate, and the rotating wheel 737 fixedly connected to the rotating card wheel 738 and the rotating card wheel 738 are driven to rotate by the belt. This in turn drives the traction chains 735 on the left and right sides to rotate, and through the rotation of the traction chains 735, the T-shaped slider 734 is driven to slide forward on the outer surface of the slide rod 739 and the inner cavity of the sliding groove 733, thereby driving the fork 71 to slide forward, so that the fork 71 is inserted into the lower side of the goods, and then the traction chain 735 is reversed to rotate, so that the T-shaped slider 734 drives the fork 71 to move backward, so that the goods arrive directly above the bottom plate 732. The same is true for stacking goods, and it is necessary to cooperate with the lifting group 6 to adjust the height to complete the cargo stacking work.

[0042] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.
