Description

Technical Field

[0001] The present invention relates to the technical field of port transportation, and particularly relates to a rapid cargo loading and unloading device for port transportation. Background Art

[0002] In port transportation, goods are often presented in the form of containers, which directly omits the unloading link of the port and realizes the function of directly docking the factory destination for unloading, greatly increasing the cargo transportation efficiency of the port. A container is a semi-closed box structure made of metal, with goods loaded inside. When loading and unloading goods, the container needs to be conveyed and moved, so a loading and unloading device is required.

[0003] In Chinese authorized publication number CN106743776B, a cargo loading and unloading device is disclosed, including a front support column, a rear support column and a cargo carrying plate. A cargo carrying plate is arranged above the front support column and the rear support column; an arc-shaped cylinder is arranged at the lowermost end of the cargo carrying plate. A sliding shaft is sleeved inside the cylinder, and a front end plate sleeve and a baffle sleeve are sleeved outside the sliding shaft. The front end plate sleeve and the baffle sleeve are respectively connected with a front end plate and a blocking member. A long hole for the front end plate and the blocking member to move along the axial direction of the cylinder is arranged on the cylinder, solving the problem of single cargo conveying direction.

[0004] Compared with the above-mentioned loading and unloading device, there are still the following defects: Generally, the volume of a container is too large. During the process of guiding the loading and unloading along its own gravity, due to the difficulty in controlling the stopping angle and speed, the goods inside the container may be damaged by collision. At the same time, when transferring from a cargo ship to a vehicle during port transportation, there is a certain height difference, and the container may shake due to wind and current during the transfer process, making it difficult to lift and lower stably.

[0020] Beneficial effects of the present invention:

[0021] 1. The conveyor roller and the rubber anti-skid sleeve are connected by wrapping and bonding. When the container is placed on the conveyor roller, it can be anti-skid under the action of the rubber anti-skid sleeve to prevent the container from displacement. The linkage shaft rod and the inner tooth adjustment belt are connected by meshing. When the conveyor roller rotates, the container can be moved to the left or right as a whole for transportation, so as to achieve the effect of fast consignment.

[0022] At the same time, when the container is located on the conveying shaft roller as a whole, since the left and right ends of the receiving platform frame are vertically fixed with fixed baffles, the left and right ends of the container can be protected. At the same time, the second servo motor is turned on to rotate the adjusting disk, so that the movable baffle engaged with the adjusting disk is lifted and lowered on the inner side of the receiving platform frame through the limiting protrusion. When the movable baffle rises to the highest end, the hydraulic telescopic rod is turned on to drive the limiting support rod to move inwards and engage with the movable baffle, so as to limit the height of the movable baffle and avoid it from falling due to its own gravity.

[0023] After the height of the movable baffle and the fixed baffle is set, it can not only protect the container from the front, back, left and right to prevent the container from falling, but also block the wind flow in the port to avoid the container shaking and displacement during the transfer process due to the influence of wind speed, causing damage to the goods inside;

[0024] 2. The movable connection block is used to form a snap-on lifting movement on the inner side of the gantry. When the motor is turned on to rotate the reel roller, the traction wire rope can be reeled in or released, thereby lifting the height of the entire receiving platform frame;

[0025] At the same time, after the extended base plate is rotated and fits the ground, the movable sleeve rod threadedly connected to the adjusting rod is rotated to make the movable sleeve rod dock and engage with the extended base plate through the limiting hole groove, so as to limit the extended base plate to improve the overall stability of the gantry, and the construction bolts can be used to penetrate the reserved hole groove to connect with the ground, which can block the wind flow around the port to a certain extent.
