Description

Technical Field

[0001] The present invention relates to the technical field of gantry cranes, and in particular to an intelligent container gantry crane. Background Art

[0002] A container is a large cargo container, commonly used for cargo turnover and transportation. When in use, the cargo is placed in the container, and the container can be directly hoisted and transported. The hoisting process has nothing to do with the shape and performance of the cargo itself, so it greatly improves the efficiency of cargo hoisting and transportation, which is very important for building a multi-turnover logistics system. Due to the large size and heavy weight of containers, special machines are usually required for hoisting, and rail-mounted gantry cranes are generally used to hoist containers.

[0003] The existing container gantry crane is mainly composed of guide rails, a gantry, a hook and a lifting rope. When in use, the container can be suspended by moving the gantry on the guide rail to the desired position, and then controlling the lifting rope to lower the hook to the desired position. Thereafter, the lifting hook and the container are lifted up together, and the container is transferred by moving the gantry. Since the lifting rope is made of flexible material, the container is very likely to swing during transfer, affecting the stability of the goods inside. Excessive shaking may cause collision and damage to the goods inside. At the same time, in the process of placing the container downward, the swing of the container will also affect the efficiency of placement, and the placement position is prone to deviation, resulting in the subsequent stability of the entire container being affected.

[0025] The rotating member 24 includes a winding wheel 25 rotatably connected to the side of the fixed frame 20, a rotating shaft 26 coaxially rotatably connected to the winding wheel 25 is fixedly connected to the side of the clamping plate 9, a first spring 27 fixedly connected to the inner wall of the winding wheel 25 is fixedly connected to the outer wall of the rotating shaft 26, a second spring 28 fixedly connected to the inner wall of the fixed frame 20 is fixedly connected to the outer wall of the rotating shaft 26, and a driving member 29 for driving the clamping plate 9 to rotate is provided on the lifting plate 17.

[0026] The driving member 29 includes a driving rod 30 fixedly installed on the top of the lifting plate 17. The driving rod 30 passes through the top of the fixed cylinder 15. The top of the driving rod 30 is fixedly connected to a connecting rod 31. Two groups of steel cables 32 are fixedly connected to the connecting rod 31. The two groups of steel cables 32 are respectively fixedly connected to the outer walls of the winding wheels 25 on both sides. One end of the steel cable 32 close to the winding wheel 25 is wrapped around the outer wall of the winding wheel 25.

[0027] In this embodiment, the gantry 1 moves on the guide rail 40, driving the guide frame 3 to move to the desired lifting position, and the driver 10 moves horizontally on the guide frame 3, driving the device box 13, the lifting rope 12 and the hook 2 to move to the upper side of the container, and the lifting rope 12 is gradually loosened by the device box 13, and the hook 2 is lowered to the desired lifting position, and the container is lifted on the hook 2. In the process of lowering and rising of the hook 2, since the bottom of the control panel 37 is not pushed, the lifting plate 17 moves downward under the push of the first spring 19, and the liquid in the fixed cylinder 15 is transported to the bellows 6 through the connecting pipe 18, so that the bellows 6 expands. At this time, the liquid pressure in the bellows 6 is relatively large, which expands the bellows 6, thereby reducing the flexibility of the bellows 6, which can reduce the swing amplitude of the hook 2 during the lifting process to a certain extent.

[0028] When the hook 2 drives the container to move upward, when the container moves up and conflicts with the bottom of the control panel 37, the control panel 37 is gradually pushed upward, and the control panel 37 drives the control rod 7 to move upward. The lifting plate 17 moves upward to gradually draw the liquid in the bellows 6 into the fixed tube 15, so as to avoid the situation in which the continuous increase of the hydraulic pressure in the bellows 6 affects the movement of the hook 2. The lifting plate 17 drives the driving rod 30 to move upward, and the driving rod 30 pushes the connecting rod 31, so that one end of the steel cable 32 is pulled up, driving the winding wheel 25 to rotate, and the winding wheel 25 drives the first clockwork spring 27 to compress, so that the rotating shaft 26 drives the clamping plate 9 to rotate, and the clamping plates 9 on both sides are synchronously flipped downward until the side of the buffer plate 22 is clamped and conflicts with the two sides of the container.

[0029] At this time, the container is still moving upward, and will roll and rub against the roller 36 on the side of the buffer plate 22. The setting of the roller 36 reduces the friction with the side of the container. At the same time, the clamping plates 9 on both sides push the two sides of the suspended container to the center. At this time, the ball 39 at the bottom of the control panel 37 can roll, reducing the friction between the container and the bottom of the control panel 37 when adjusting.

[0030] When the container is lifted to the required height, the drive 10 and the gantry 1 can be controlled to move and drive the container to the required position for unloading. During this process, the container is fixed and limited by the clamping plate 9, which can effectively reduce the shaking amplitude during the movement. During unloading, the container moves down, and the clamping plates 9 on both sides are gradually loosened to both sides. At this time, the driving disk and the driving rod 30 move down synchronously. Under the push of the first spring 19, the liquid in the fixed cylinder 15 is pushed into the bellows 6 again, slowing down the swing amplitude of the hook 2 and improving the efficiency of placing the container to the set position. The driving rod 30 and the connecting rod 31 move down to gradually reduce the pulling force on the steel cable 32, and the first spring 27 and the second spring 28 gradually rebound, which can drive the rotating shaft 26 to rotate in the opposite direction, so that the clamping plate 9 flips upward and resets, and at the same time, the winding wheel 25 rotates in the opposite direction to rewind the steel cable 32 to the outer wall of the winding wheel 25 for reset.
