[0036] like Figure 1-12 As shown, the utility model is an electrically-operated two-layer sealed cabin, comprising a cabin body, wherein the cabin body is enclosed by a front wall assembly 1, a rear door assembly 2, a bottom frame assembly 3, a top plate assembly 4 and two side plate assemblies 5 to form a sealed structure.

[0037] A plurality of two-layer movable platforms 6 which can be raised and lowered and are independent of each other are arranged inside the compartment along its length direction. Each of the two-layer movable platforms 6 is driven to rise and fall by a corresponding lifting drive mechanism 7 .

[0038] Lifting guide columns 8 are fixed on both sides of the box body corresponding to each second-layer movable platform 6, and lifting guide grooves 81 are arranged along the vertical direction on the lifting guide columns 8. Load-bearing guide seats 61 are fixed on the sides of the second-layer movable platform 6 corresponding to each lifting guide groove 81. In this embodiment, load-bearing guide seats 61 are fixed to the four corners of the second-layer movable platform 6, and the load-bearing guide seats 61 at the four corners are respectively slidably connected to the corresponding lifting guide grooves 81. This design can effectively improve the stability of the second-layer movable platform 6 during the lifting process.

[0039] The load-bearing guide seat 61 is composed of two bent pieces 611 that are fixed by welding. The four corners of the load-bearing guide seat 61 are all bent and rounded to reduce the resistance during the rising and falling process. In addition, a sealing plate 612 is welded and fixed at the outer open end of the load-bearing guide seat 61 to increase the strength of the load-bearing guide seat 61.

[0040] The lifting guide column 8 located at the corner of the compartment has only one lifting guide groove 81 structure, while the lifting guide column 8 located in the middle of the compartment (not the corner) has two guide groove structures. The two adjacent lifting guide grooves 81 are separated by a blocking plate 83, which can block the adjacent movable positioning pins 9 and prevent the movable positioning pins 9 from moving during transportation.

[0041] One or more positioning pin holes 82 are provided on both sides of the lifting guide groove 81 in the vertical direction. When the second-layer movable platform 6 is lifted to the desired position, the head of the movable positioning pin 9 is inserted into the positioning pin hole 82 and supported under the corresponding load-bearing guide seat 61, thereby supporting and positioning the second-layer movable platform 6. The positioning pin hole 82 adopts a special-shaped hole structure, and the positioning pin hole 82 is composed of a horizontally arranged A port and a vertically arranged B port. The A port and the B port are connected to each other, and the A port is located above the B port.

[0042] The movable positioning pin 9 is inserted from the A port and moves horizontally down to the B port. Since the head of the movable positioning pin 9 adopts a square steel structure, after the positioning pin is inserted into the special-shaped hole, the movable positioning pin 9 can be effectively prevented from running and rotating, thereby ensuring the stability of the second-layer movable platform 6 during transportation. In addition, shock-absorbing silicone sleeves 91 are respectively provided at both ends of the head of the movable positioning pin 9. By installing the shock-absorbing silicone sleeve 91, the sound of the second-layer movable platform 6 when it is descending and contacting the movable positioning pin 9 can be reduced, and the vibration of the second-layer movable platform 6 during transportation of the carriage can also be reduced.

[0043] The lifting drive mechanism 7 in the utility model can achieve faster results than hydraulic system and manual operation through the combination of motor and steel wire, with lower labor intensity and higher loading and unloading efficiency. The specific lifting drive mechanism 7 includes a driving motor 71, a motor main steel wire 72 and a second-layer lifting steel wire 73. The driving motor 71 is controlled by a second-layer lifting wire control switch 74. The output end of the driving motor 71 is connected to a retractable shaft driven by it. One end of the motor main steel wire 72 is wound on the retractable shaft. The other end of the motor main steel wire 72 passes through the bottom directional wheel 75, passes through the top side beam wire routing sleeve 76, and then passes through the top cross beam directional wheel A712. Before approaching the top cross beam directional wheel B77, the motor main steel wire 72 is finally wound on the retractable shaft. The tail end of the steel wire 72 forms a rewinding portion and is locked with a double clamp of the steel wire rope; after one end of the second-layer lifting wire 73 is fixed to the eye bolt on the side of the second-layer movable platform 6I, the other end of the second-layer lifting wire 73 passes through the top side beam directional wheel B711, then passes through the top cross beam directional wheel B77, and then passes through the rewinding portion of the tail end of the motor main steel wire 72, then rewinds and enters the top cross beam directional wheel B77, and then passes through the top longitudinal beam directional wheel A78, and finally the second-layer lifting wire 73 is fixed on the eye bolt on the side of the second-layer movable platform 6II.

[0044] Upper limit travel switches 79 are respectively provided on the upper part of the compartment body corresponding to each second-layer movable platform 6, and a balance plate 710 is fixed to the upper end of the lifting guide groove 81.

[0045] The working principle of this utility model:

[0046] 1. When only one layer of cargo is loaded, after the driving motor 71 is powered on, the second-layer movable platform 6 is lifted to the highest position through the second-layer lifting wire control switch 74. When the second-layer movable platform 6 contacts the upper limit travel switch 79, the upper limit travel switch 79 cuts off the power supply for controlling the rise. At this time, the second-layer movable platform 6 will not rise when the second-layer lifting wire control switch 74 is pressed, which effectively ensures that the second-layer movable platform 6 will not cause the danger of the wire rope clamp being loosened due to unlimited rise. On the other hand, after the front and rear sides of the second-layer movable platform 6 contact the balance plate 710, it can ensure that the second-layer movable platform 6 maintains the overall balance of the second-layer movable platform 6 after it stops contacting the upper limit travel switch 79, so as to facilitate the insertion of the movable positioning pin 9.

[0047] 2. After the second-layer movable platform 6 rises to the highest position, insert the middle movable positioning pin 9 into the positioning pin hole 82 at the top of the lifting guide groove 81, and then lower the second-layer movable platform 6 onto the movable positioning pin 9 to ensure that the steel wire is not stressed during the transportation of the vehicle, and the movable positioning pin 9 is stressed to ensure safety.

[0048] 3. When the second layer of goods needs to be loaded, the second layer movable platform 6 is raised through the second layer lifting wire control switch 74, and the movable positioning pin 9 is placed on the middle hole of the second layer lifting slide. According to the height of the pallet goods, a suitable hole is selected, and the movable positioning pin 9 is placed into the hole. Then, the second layer movable platform 6 is lowered to the middle movable positioning pin 9, and the first and second layer goods are loaded.

[0049] 4. Since the movable positioning pin 9 is movable, the second-layer movable platform 6 can be raised to the top or lowered to the bottom plate of the carriage.

[0050] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications are all within the scope of protection of the present invention.
