It is a kind of lifting machinery with the widest application range and the largest quantity.

[0003] However, the existing anti-collision protection structure for the girder of a quay container crane protects the main girder through the action of a buffer plate. For example, an anti-collision protection structure for the girder of a quay container crane with the application number: "CN202323318145.X" includes a housing structure.

Moreover, when the buffer plate is impacted too many times and is damaged, it cannot continue to protect the main girder, resulting in the main girder being impacted again and being directly damaged. Content of the Utility Model

[0011] Beneficial effects

[0012] The utility model provides an anti-collision protection structure for the girder of a quay container crane, which has the following beneficial effects: Through the cooperation among the rubber buffer pad, the spring and the airbag, when the bottom of the main girder is impacted by a container, most of the impact force will be first dissipated by the airbag. If the impact force is too large and causes the airbag to be damaged, due to the plug-in relationship between the plugs on both sides of the airbag and the main girder, the airbag can be replaced. Then, through the cooperation among the anti-collision plate, multiple springs and the rubber buffer pad, other impact forces received by the main girder can be further reduced, avoiding damage to the main girder caused by impact.

[0013] Through the cooperation among the servo motor, the clamping plate and the strong magnet, when it is necessary to carry a container on the ground, the outer shell moves downward through the electric hoist. Then, the servo motor is started, and the output end of the servo motor drives the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw drives the two sleeves on the outer wall to move. The sleeves move in opposite directions, which can drive the two clamping plates to move in opposite directions until they are tightly abutted against both sides of the container. The container is lifted under the action of the electric hoist through the clamping of the clamping plates for the carrying work. The strong magnet can further ensure that the container will not fall during the carrying process. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] The existing anti-collision protection structure of the large beam of the quay container crane uses a single buffer plate to protect the main beam, which cannot fully protect the main beam. Moreover, when the buffer plate is impacted too many times and is damaged, it cannot continue to protect the main beam, resulting in the main beam being impacted again and directly damaged.

[0023] In view of this, the present invention provides an anti-collision protection structure for the large beam of a quay container crane. Through the cooperation among the rubber buffer pad, the spring and the airbag, when the bottom of the main beam is impacted by a container, most of the impact force will be first dissipated by the airbag. If the impact force is too large and causes the airbag to be damaged, due to the plug-in relationship between the insertion blocks on both sides of the airbag and the main beam, the airbag can be replaced. Then, through the cooperation among the anti-collision plate, multiple springs and the rubber buffer pad, the other impact forces received by the main beam can be further reduced, avoiding damage to the main beam caused by impact.

[0024] Those skilled in the art connect the components in this case in sequence. For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process.

[0025] Embodiment 1: Consisting of Figures 1 to 6It can be seen that an anti-collision protection structure for the girder of a quay container crane includes two main girders 1. A protection device is provided at the bottom of the main girder 1. The protection device includes a buffer rubber pad 19, a spring 20, an anti-collision plate 21, an airbag 22, and an insertion block 23. The top of the buffer rubber pad 19 covers the bottom of the main girder 1. An anti-collision plate 21 is provided below the buffer rubber pad 19. The outer wall of the anti-collision plate 21 is fixedly connected to the inner wall of the main girder 1. A plurality of springs 20 are installed between the buffer rubber pad 19 and the anti-collision plate 21. An airbag 22 is provided below the anti-collision plate 21. Insertion blocks 23 are fixedly connected to both sides of the outer wall of the airbag 22. The outer walls of the two insertion blocks 23 are inserted into the inner wall of the main girder 1. Relying on the relationship between the insertion of the insertion block 23 into the inner wall of the main girder 1 and the fixed connection between the insertion block 23 and the airbag 22, the airbag 22 can be replaced when it is damaged;

[0026] In the specific implementation process, it is particularly worth noting that when the bottom of the main girder 1 is hit by a container, most of the impact force will be first dissipated by the airbag 22. If the impact force is too large and causes the airbag 22 to be damaged, due to the relationship between the insertion blocks 23 on both sides of the airbag 22 and the main girder 1, the airbag 22 can be replaced. Then, through the cooperation between the anti-collision plate 21, a plurality of springs 20, and the buffer rubber pad 19, other impact forces received by the main girder 1 can be further reduced, avoiding damage to the main girder 1 caused by impact;

[0027] Specifically, when using the anti-collision protection structure for the girder of the quay container crane, when the bottom of the main girder 1 is hit by a container, most of the impact force will be first dissipated by the airbag 22. If the impact force is too large and causes the airbag 22 to be damaged, due to the relationship between the insertion blocks 23 on both sides of the airbag 22 and the main girder 1, the airbag 22 can be replaced. Then, through the cooperation between the anti-collision plate 21, a plurality of springs 20, and the buffer rubber pad 19, other impact forces received by the main girder 1 can be further reduced, avoiding damage to the main girder 1 caused by impact.

[0028] Embodiment 2: It can be seen that Figures 1 - 4 a connecting beam 13 is fixedly connected between the two main girders 1. Support brackets 14 are provided on both sides of the bottom of the two main girders 1. The two main girders 1 are fixedly connected through the support brackets 14. A reinforcing frame 17 is fixedly connected to the inner wall of the support bracket 14. A first electric slide rail 16 is provided below the support bracket 14. A first electric slider 15 fixedly connected to the bottom of the support bracket 14 is installed on the surface of the first electric slide rail 16. The models of the first electric slider 15 and the first electric slide rail 16 are not specifically described here;

[0029] In the specific implementation process, it is particularly worth noting that the two main beams 1 are fixedly connected by a connecting beam 13. The brackets 14 fixedly connected to the bottom of the main beam 1 can bear the main beam 1. The reinforcement frames 17 fixedly connected between the brackets 14 can ensure the stability of the brackets 14. The two first electric slide rails 16 can be installed on both sides of the shore. Then, the brackets 14 can move on the outer wall of the first electric slide rail 16 under the drive of the first electric slider 15, so as to achieve the handling of the container.

[0030] Furthermore, a housing 12 is provided below the main beam 1. The inner wall of the housing 12 is rotatably connected to a bidirectional lead screw 24 through a bearing. One side of the housing 12 is fixedly connected to a servo motor 18. The output end of the servo motor 18 passes through the side of the housing 12 through a bearing and is fixedly connected to one end of the bidirectional lead screw 24. Both sides of the outer wall of the bidirectional lead screw 24 are threadedly connected with sleeves 25. The backs of the two sleeves 25 are both fixedly connected to a straight plate 5. One end of each of the two straight plates 5 penetrates through both sides of the housing 12 respectively. The straight plate 5 can be telescoped on the side of the housing 12 through the drive of the sleeve 25, so as to drive the two clamping plates 4 to approach or move away from each other to achieve clamping. The bottoms of the two straight plates 5 on the outer side of the housing 12 are both fixedly connected to clamping plates 4. Powerful magnets 3 are installed on one side of the two clamping plates 4 close to each other. The powerful magnets 3 can adsorb the outer wall of the container to prevent it from falling during the handling process. Both sides of the top of the housing 12 are fixedly connected to rings 11.

[0031] In the specific implementation process, it is particularly worth noting that when it is necessary to handle the container on the ground, the housing 12 moves downward through the electric hoist 7. Then, the servo motor 18 is started. The output end of the servo motor 18 drives the bidirectional lead screw 24 to rotate. The rotation of the bidirectional lead screw 24 drives the two sleeves 25 on the outer wall to move. The sleeves 25 move in opposite directions, which can drive the two clamping plates 4 to move in opposite directions until they are in contact with both sides of the container. The container is lifted under the action of the electric hoist 7 through the clamping of the clamping plates 4 for the handling work. The powerful magnets 3 can further ensure that it will not fall during the handling process.

[0032] Furthermore, a movable plate 8 is provided above the main beam 1. An electric hoist 7 is fixedly connected to the top of the movable plate 8. Two iron chains 6 are installed inside the electric hoist 7. The bottoms of the two iron chains 6 are both fixedly connected to hook bodies 10. The two hook bodies 10 are respectively movably connected to the two rings 11. The model of the electric hoist 7 is not specifically limited here.

[0033] In the specific implementation process, it is particularly worth noting that by retracting and releasing the two iron chains 6 through the electric hoist 7, the purpose of moving the container up and down can be achieved.

[0034] Furthermore, second electric slide rails 2 are fixedly connected to the tops of both main beams 1. Second electric sliders 9 are slidably clamped to the outer walls of the two second electric slide rails 2. The bottom of the movable plate 8 is fixedly connected to the top of the second electric slider 9. The models of the second electric slider 9 and the second electric slide rail 2 are not specifically described herein;

[0035] In the specific implementation process, it is particularly worth noting that the movable plate 8 moves on the outer wall of the second electric slide rail 2 driven by the second electric slider 9. The movable plate 8 transports the container through the actions of the electric hoist 7, the iron chain 6, and the hook body 10;

[0036] Specifically, on the basis of the above-mentioned Embodiment 1, the two main beams 1 are fixedly connected by a connecting beam 13. The brackets 14 fixedly connected to the bottom of the main beam 1 can support the main beam 1. The reinforcing frames 17 fixedly connected between the brackets 14 can ensure the stability of the brackets 14. The two first electric slide rails 16 can be installed on both sides of the shore. Then, the brackets 14 can move on the outer wall of the first electric slide rail 16 driven by the first electric slider 15. When it is necessary to transport the container on the ground, the outer shell 12 moves downward through the electric hoist 7. Then, the servo motor 18 is started. The output end of the servo motor 18 drives the bidirectional lead screw 24 to rotate. The rotation of the bidirectional lead screw 24 drives the two sleeves 25 on the outer wall to move. The sleeves 25 move in opposite directions, which can drive the two clamping plates 4 to move in opposite directions until they abut against both sides of the container. The container is lifted under the action of the electric hoist 7 through the clamping of the clamping plates 4 for the transportation work. The strong magnet 3 can further ensure that it will not fall during the transportation process. By retracting and releasing the two iron chains 6 through the electric hoist 7, the purpose of moving the container up and down can be achieved.
