[0032] First, move the device to the storage place of the wooden box equipped with electrical equipment through the moving seat 1, then twist the fastening bolt 131 in reverse, the fastening bolt 131 reverses and moves forward through the thread, when the fastening bolt 131 moves forward and disengages from the nut 132, the fastening bolt 131 stops locking the cover 4, stop twisting the fastening bolt 131, start the stepper motor 137 to rotate forward, the stepper motor 137 rotates forward through the synchronous belt assembly to drive the rotating rod 134 to rotate forward, the rotating rod 134 rotates forward to drive the winding roller 135 to rotate forward, the winding roller 135 rotates forward to reel the pull rope 136, the reeling of the pull rope 136 drives the cover 4 to swing upward and open, when the cover 4 swings upward ninety degrees, turn off the stepper motor 137, and then start the electric screw 121 to rotate forward to drive the slider 12 to move forward The slider 12 moves forward to drive the placement seat 5 to move forward, and the placement seat 5 moves forward to drive the universal wheel 122 to move forward. The universal wheel 122 moves forward and slides on the ground. The universal wheel 122 guides the placement seat 5. When the placement seat 5 moves forward to the maximum stroke, the electric screw 121 is turned off, and the placement seat 5 stops moving forward. Then the staff can move the wooden box with electrical equipment to the placement seat 5. Due to the large differences in specifications and sizes of electrical equipment, the sizes of wooden boxes used to package electrical equipment are also different. When the placement seat 5 is stacked with a proper amount of wooden boxes, the height of the top wooden box is also different. The electric screw 121 is started to reverse and drive the slider 12 to move backward. The slider 12 drives the placement seat 5 to move backward. The placement seat 5 drives the universal wheel 122 to move backward. The wheel 122 and the wooden box with the electrical equipment move backward, and the wooden box with the electrical equipment moves backward into the housing 2. When the placement seat 5 moves backward and resets, the electric screw 121 is turned off, and the drive motor 11 is started to rotate forward to drive the drive screw 111 to rotate forward. The drive screw 111 rotates forward to drive the movable plate 7 to move downward. The movable plate 7 drives the pressure plate 9 to move downward through the connecting spring 10. The pressure plate 9 moves downward and contacts the top wooden box. The pressure plate 9 cooperates with the placement seat 5 to press and fix the wooden box with the electrical equipment. The pressure plate 9 in contact with the wooden box stops moving downward, and the pressure plate 9 not in contact with the wooden box continues to move downward. At the same time, the movable plate 7 continues to move downward to compress the connecting spring 10. As the pressure plate 9 not in contact with the wooden box continues to move downward and contacts the wooden box, The pressing plate 9 presses and fixes the wooden box, so that the pressing plate 9 can adapt to the height of the wooden box to press and fix all the wooden boxes on the placement seat 5 to prevent the wooden box and the electrical equipment inside from shaking and causing damage, thereby improving the safety of electrical equipment transportation.

[0035] When the electric screw 121 starts to rotate forward so that the slider 12 drives the placement seat 5 to move forward, the placement seat 5 drives the guide plate 14 to move forward, and at the same time, the slider 12 moves forward to drive the cross plate 141 to move forward, the cross plate 141 drives the first cylinder 143 to move forward, the first cylinder 143 drives the first piston rod 144 to move forward, and the cross plate 141 also drives the second cylinder 148 to move forward through the fixed column 147, the second cylinder 148 moves forward to drive the second piston rod 149 to move forward, the second piston rod 149 moves forward synchronously with the guide plate 14, when the first piston rod 144 moves forward and contacts with the trigger plate 142, the trigger plate 142 limits the first piston rod 144, so that the first piston rod 144 stops moving forward, and the first cylinder 143 continues to move forward to reset The spring 145 is compressed, and at the same time, the first piston rod 144 pushes the air in the first cylinder 143 into the hose 146, and the air in the hose 146 is discharged into the second cylinder 148. As the air is discharged, the air pushes the second piston rod 149 to move forward, and the second piston rod 149 moves forward to push the guide plate 14 to swing upward and be in a tilted state. When the first cylinder 143 moves forward to the maximum stroke, the electric screw 121 is closed, the slider 12 stops driving the cross plate 141 to move forward, and the cross plate 141 stops driving the first cylinder 143 to move forward. The staff can push the electrical equipment onto the placement seat 5 through the tilted guide plate 14. The tilted guide plate 14 can guide the wooden box with the electrical equipment, so that the wooden box with the electrical equipment can be better moved to the placement seat 5. When a proper amount of electrical equipment is placed on the placement seat 5, the electric screw 121 is started to reverse and drive the slider 12 to move backward and reset, the slider 12 drives the placement seat 5 to move backward and reset, the placement seat 5 drives the wooden box with the electrical equipment to move backward into the housing 2, and at the same time, the placement seat 5 moves backward and drives the guide plate 14 to move backward, and the slider 12 moves backward and drives the cross plate 141 to move backward, the cross plate 141 drives the first cylinder 143 to move backward, the first cylinder 143 moves backward first to reset the reset spring 145, and at the same time, the first cylinder 143 moves backward and resets the reset spring 145.

As the air is drawn away, the second cylinder 148 is in a negative pressure state, causing the second piston rod 149 to move backward and retract. The second piston rod 149 retracts and disengages from the guide plate 14. Due to the effect of gravity, the guide plate 14 swings downward to reset.

In this way, it is more convenient to move the wooden box containing the electrical equipment to and from the placement seat 5, thereby improving the efficiency of loading and unloading.

[0036] When the placement seat 5 drives the wooden box containing electrical equipment to move backward into the shell 2, the rodless cylinder 15 is started to drive the left and right vertical plates 151 to move towards each other, and the vertical plates 151 drive the left and right positioning plates 153 to move towards each other through the compression springs 154. The left and right positioning plates 153 are in contact with the wooden boxes, and the positioning plates 153 push and press the stacked wooden boxes from both sides to make the adjacent wooden boxes in closer contact. After the wooden boxes are in close contact, the positioning plates 153 stop moving, and the vertical plates 151 continue to move to compress the compression springs 154. The rodless cylinder 15 is closed, the vertical plates 151 stop moving, and the electrical equipment can be transported. When the electrical equipment is transported to the designated location, the rodless cylinder 15 is started to drive the left and right vertical plates 151 to move away from each other. The vertical plates 151 first reset the compression springs 154, and then the vertical plates 151 drive the left and right positioning plates 153 to move away from each other through the compression springs 154. The positioning plates 153 are reset and disengaged from the wooden box containing the electrical equipment. In this way, the wooden box containing the electrical equipment can be transported more stably, thereby further improving the safety of transportation.

[0037] See also Fig.10 As shown, the electrical equipment transport box also includes a fan 16 . The fan 16 is installed in the middle of the rear side of the shell 2 . When the fan 16 rotates, the fan 16 can ventilate the inside of the shell 2 .
