By setting the third electric push rod 15, the third electric push rod 15 is connected with the tooth plate 16, the fixed block 18, the support plate 19 and the dovetail block 28, which together constitute the limit assembly. When the third electric push rod 15 is started, they push the tooth plate 16 and other components to slide relatively in the dovetail groove 29. This sliding is precisely controlled to ensure that the limit assembly can be adjusted according to the specific width of the container. Through the coordinated use of the first electric push rod 5 and the third electric push rod 15, the movable assembly and the limit assembly can be precisely adjusted. This adjustment is real-time and can quickly respond to changes in container size; The two third electric push rods 15 are fixedly connected to a toothed plate 16 at one end away from each other. The tops of the two toothed plates 16 are provided with a fixing groove 17. By providing the fixing groove 17, the fixing groove 17 and the fixing block 18 cooperate with each other to avoid the fixing block 18 from being offset and stuck during movement, thereby ensuring the stable movement of the fixing block 18.

[0025] In some examples, the sides of the two movable seats 11 are provided with inclined grooves 30, the fixed columns 9 are slidably connected in the inclined grooves 30, and the top of the support platform 6 is provided with sliding grooves 31. By setting the sliding grooves 31, and the mutual cooperation between the sliding grooves 31 and the fixed rod 8, it is possible to avoid the fixed rod 8 from being offset and stuck during movement, thereby ensuring the temperature movement of the fixed rod 8, and the fixed rod 8 is slidably connected in the sliding grooves 31.

[0027] In some examples, two first infrared sensors 33 are provided on the front side of the support platform 6, and a second infrared sensor 34 is provided on the front side of the support plate 19. The first infrared sensor 33 and the second infrared sensor 34 play a key role in the adjustment process.

The control box 35 accurately controls the start, stop and force of the electric push rod according to the data provided by the sensor, thereby achieving accurate limit; The positive poles of the first infrared sensor 33 and the second infrared sensor 34 are both electrically connected to the positive pole of the power supply of the control box 35, the negative poles of the first infrared sensor 33 and the second infrared sensor 34 are both electrically connected to the negative pole of the power supply of the control box 35, the output ends of the first infrared sensor 33 and the second infrared sensor 34 are electrically connected to the input end of the control box 35, the positive and negative poles of the first electric push rod 5 and the third electric push rod 15 are both electrically connected to the power output end of the control box 35, and the output end of the control box 35 is electrically connected to the control ends of the first electric push rod 5 and the third electric push rod 15 respectively.

[0028] S1 uses bolts to install the anti-roll device on both sides of the crane body 1, and ensures that the oil absorption layer 27 is tightly fitted with the wire rope; S2 moves the spreader 3 to the top of the container for fixing; S3 starts the crane body 1 to prepare to lift the container, starts the first electric push rod 5, pushes the support platform 6 to move downward, and the guide telescopic rod 4 stretches with the movement of the support platform 6 to provide stability; S4 When the first infrared sensor 33 detects the container, the first electric push rod 5 stops moving, and the two third electric push rods 15 are started to adjust the positions of the tooth plate 16, the fixing block 18, the support plate 19 and the dovetail block 28 to adapt to the width of the container. When the second infrared sensor 34 senses the width of the container, the third electric push rods 15 stop; S5 starts the second electric push rod 7, pushes the fixed rod 8, the movable plate 13 and the first limit plate 14 to move forward, and adjusts the second limit plate 23 to the front through the relative rotation of the gear 21 and the gear rod 22 to limit the left and right sides of the container. The two first limit plates 14 limit the front and rear sides of the container at the same time; When the fixed rod 8 moves in the slide groove 31, the fixed column 9 is driven to slide in the inclined groove 30, squeezing the movable seat 11 and the pressing plate 12. The pressing plate 12 squeezes the pressing nozzle 25, spraying the lubricant to the oil absorption layer 27 to lubricate the wire rope; When the S7 lifting device 3 lifts the container, the first electric push rod 5 drives the support platform 6 to rise synchronously, further maintaining the stability of the container.

[0029] The working principle of the present invention is: When using the device, firstly, the device is installed on both sides of the crane body 1 by bolts, and the oil absorption layer 27 is kept in contact with the wire rope. When in use, the sling 3 can be moved to the top of the corresponding container for fixing, and then the crane body 1 is started, and the container can be lifted by the sling 3. When lifting, the first electric push rod 5 is started synchronously, and the first electric push rod 5 pushes the support platform 6 to move downward, and drives the corresponding two guide telescopic rods 4 to be in a stretched state. Then, when the first infrared sensor 33 senses the container, the first electric push rod 5 stops; Then the two third electric push rods 15 can be started, and the two third electric push rods 15 can push the two toothed plates 16, the fixed block 18, the support plate 19 and the dovetail block 28 to slide relatively in the two dovetail grooves 29 until the two second infrared sensors 34 sense the width of the container and stop. Finally, the second electric push rod 7 can be started, and the second electric push rod 7 can push the fixed rod 8, the movable plate 13 and the first limit plate 14 to move forward, and drive the two second electric push rods 7 and the toothed plate 16 to move forward outside the fixed block 18, and can drive the two gears 21 and the fixed shaft 20 to rotate relative to each other, and then drive the two toothed rods 22 and the other two fixed shafts 20 to rotate in the opposite direction, so that the second limit plate 23 can be driven to rotate to the front, so that the left and right sides of the container can be limited. At the same time, the first limit plate 14 can limit the front and rear sides of the container. When the fixed rod 8 moves forward in the slide groove 31, it can drive the two fixed columns 9 to slide forward in the two inclined grooves 30, and can synchronously squeeze the two moving seats 11, so that the two moving seats 11 can drive the two pressing plates 12 to squeeze the pressing nozzle 25, so that the lubricant can be sprayed out from the storage box 24 and absorbed by the oil absorption layer 27. When the support platform 6 moves up and down, it can drive the support rod 26 and the oil absorption layer 27 to move synchronously, so that it can continuously lubricate and maintain the wire rope; Finally, when the lifting device 3 lifts the container, the first electric push rod 5 can drive the support platform 6 to rise synchronously, so as to further maintain the stability of the container.

[0030] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

By the relative rotation of the gear (21) and the gear rod (22), the second limit plate (23) is adjusted to the front to limit the left and right sides of the container, and the two first limit plates (14) simultaneously limit the front and rear sides of the container; When the S6 fixed rod (8) moves in the slide groove (31), it drives the fixed column (9) to slide in the inclined groove (30), thereby squeezing the movable seat (11) and the pressure plate (12). The pressure plate (12) squeezes the pressing nozzle (25), spraying lubricant to the oil absorption layer (27), thereby lubricating the wire rope; When the S7 lifting device (3) lifts the container, the first electric push rod (5) drives the support platform (6) to rise synchronously, thereby further maintaining the stability of the container.
