[0002] Container reach crane, referred to as reach crane, commonly known as container reach crane or reach crane. Container reach crane is a kind of crane used to load and unload containers. It is a kind of lifting equipment and can also be said to be a mobile machinery. It is mainly used for stacking containers and horizontal transportation in docks and storage yards. Compared with forklifts, it has the advantages of flexibility, easy operation, good stability, low wheel pressure, high stacking layers, high utilization rate of storage yards, etc., and can perform cross-container operations.

[0003] At present, some reach stackers have only one hook. When a single hook lifts objects of different lengths, workers are required to judge the lifting center of gravity based on their own experience, and then tie the slings in advance for lifting. This working method is time-consuming and labor-intensive, greatly reduces work efficiency, and is difficult to control the lifting center of gravity. The goods are prone to tilt during the lifting process, posing a safety hazard. For this reason, we have designed a special reach stacker to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 5 A special sling for a front crane comprises a main beam 1 and two cross beams 2, the two cross beams 2 are welded at both ends of the main beam 1, and the upper ends of the two cross beams 2 are symmetrically provided with two connecting pieces for connecting with the lifting equipment, the connecting pieces comprise a connecting block 3 welded to the upper end of the cross beam 2, a slot 4 is provided at the upper end of the connecting block 3, and locking grooves 5 which are interconnected with the slots 4 are provided through the front and rear of the connecting block 3, wherein a plurality of annular plugs are installed on the lifting equipment, the annular plugs are inserted into the corresponding slots 4, and the bolts pass through the locking grooves 5 and the annular plugs, so that the annular plugs can be stably connected with the connecting blocks 3, and then the sling can be stably installed on the lifting equipment, and the setting of a plurality of connecting pieces can ensure the stability of the installation and prevent the sling from tilting due to uneven gravity;

[0024] The front and rear side walls of the main beam 1 are fixedly connected with a plurality of first reinforcing ribs 8, and the inner side walls of the two cross beams 2 are fixedly connected with the main beam 1 with at least one second reinforcing rib 9, which can ensure the strength of the main beam 1 and the cross beam 2;

[0025] A first hook 11 is detachably connected to the middle of the main beam 1, and a mounting seat 10 is connected to the main beam 1 by bolts. The first hook 11 is installed on the mounting seat 10. The first hook 11 can be disassembled and installed by disassembling and installing the mounting seat 10. The first hook 11 is arranged in the middle of the main beam 1, which can ensure the stability of the sling during the lifting of goods. A driving assembly is installed at the bottom of the main beam 1, and the driving assembly includes a guide slide 12 opened at the bottom of the main beam 1. Two connecting sliders 13 are slidably connected in the guide slide 12. The connecting slider 13 is adapted to the guide slide 12 so that the connecting slider 13 can only slide horizontally in the guide slide 12. A double-headed screw 14 is rotatably connected to the inner side wall of the guide slide 12. The double-headed screw 14 thread penetrates the two connecting sliders 13. The rotation of the double-headed screw 14 can make the two connecting sliders 13 approach or move away from each other under the action of the thread meshing. The double-headed screw 14 is driven to rotate by a servo motor 15 installed on the outside of one of the crossbeams 2;

[0026] Two second hooks 6 are symmetrically and detachably connected to the bottom of the driving component. The driving component drives the two second hooks 6 to move closer to or away from each other. The bottom of the connecting slider 13 is connected to a mounting plate 16 by screws. The second hook 6 is fixed to the bottom of the mounting plate 16. The mounting plate 16 is installed on or removed from the connecting slider 13 by screws. The second hook 6 can be installed and removed. A counterweight block 7 matching the servo motor 15 is fixedly connected to the side wall of the other crossbeam 2. The setting of the counterweight block 7 can cooperate with the servo motor 15 to ensure the stability of the sling.

[0027] The functional principle of the utility model can be explained through the following operation modes:

[0028] In the utility model, when the front-end crane special sling is in use, the annular plug block on the lifting device is inserted into the corresponding slot 4, and the bolt is passed through the locking groove 5 and the annular plug block, so that the annular plug block and the connecting block 3 can be stably connected, and then the sling can be stably installed on the lifting device. The setting of multiple connecting parts can ensure the stability of the installation and prevent the sling from tilting due to uneven gravity.

[0029] The cargo to be lifted can be lifted by hanging it on the first hook 11. The first hook 11 is located in the middle of the main beam 1, which can ensure the stability of the lifting device during the lifting process. The cargo is further hung by two second hooks 6, which can ensure the stability and safety of the cargo during the lifting process.

[0030] Starting the servo motor 15 drives the double-headed screw 14 to rotate, which can make the two connecting sliders 13 approach or move away from each other under the action of the thread meshing, and then make the two second hooks 6 approach or move away from each other, so as to meet the lifting requirements of goods of different sizes.
