Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0031] Example 1

[0032] This embodiment discloses a cable reel locking device for a quay crane trolley, such as Figure 1-Figure 4 As shown, it includes a trolley cable turntable 2 and a cable 3, a traction rope 4, a hook 5 and a locking assembly 6 wound around the trolley cable turntable 2.

[0033] First, the trolley cable turntable 2 is a rotatable mechanism for winding and releasing the cable 3, and the cable 3 is wound on the trolley cable turntable 2 according to the required length. The hook 5 is hung on the trolley cable turntable 2 and connected to the locking assembly 6 through the traction rope 4. The traction rope 4 is used to pull the hook 5, thereby adjusting the tension of the cable 3.

[0034] The locking assembly 6 includes a bottom shell 63, which serves as the basic structure of the locking assembly 6 and is fixed on the platform 1. The bottom of the bottom shell 63 is fixedly connected to the platform 1, and both ends of the roller 60 are connected to the rotating shaft of the bottom shell 63, and the roller 60 can rotate in the bottom shell 63. Both ends of the roller 60 extend to the outside of the bottom shell 63 and are respectively connected to the tensioning member 61 and the locking member 62. The tensioning member 61 and the locking member 62 are respectively arranged on both sides of the roller 60 to control the tensioning of the traction rope 4 and the clamping of the roller 60 respectively.

[0035] The tensioning member 61 includes a driving wheel 610, a driven wheel 611 and a driving motor. The driving wheel 610 and the driven wheel 611 are meshed with each other to form a transmission system. The driving motor provides power to drive the driving wheel 610 to rotate, thereby driving the driven wheel 611 to rotate. The driven wheel 611 is connected to one end of the roller 60 to transmit power to the roller 60.

[0036] Specifically, the diameter of the driven wheel 611 is greater than the diameter of the driving wheel 610. This design can increase the transmission ratio and improve the tensioning efficiency.

[0037] In addition, the locking member 62 includes a locking disk 620, a bracket 622 and a top pin 623; the locking disk 620 is fixedly connected to the roller 60 and is arranged concentrically with the roller 60. The rotation of the roller 60 can drive the locking disk 620 to rotate together. One end of the bracket 622 is connected to the bottom shell 63, and the other end is located above the locking disk 620. The top pin 623 is connected to the bracket 622, faces the locking disk 620, and cooperates with the bayonet 621 on the outer periphery of the locking disk 620.

[0038] When it is necessary to lock the cable 3, firstly, the hook 5 at one end of the traction rope 4 is operated to catch the trolley cable turntable 2, and the other end of the traction rope 4 is connected to the roller. The tensioning member 61 then works to rotate the roller 60 by some mechanical or electrical means, and tightens the traction rope 4 through the connection between the roller 60 and the traction rope 4.

[0039] At the same time, the locking member 62 starts to work on the other side of the roller 60. When the tension of the traction rope 4 presses the hook 5 tightly against the trolley cable turntable 2, the locking member 62 can perform the locking operation to lock the trolley cable turntable 2.

[0040] When the cable 3 needs to be unlocked, the locking of the roller 60 is released by operation. Then, the tensioning member 61 works in the reverse direction to make the roller 60 rotate in the reverse direction, and the traction rope 4 gradually relaxes. At this time, the hook 5 only needs to be removed to complete the unlocking process. Through the above working principle, the device can achieve stable locking and unlocking of the cable 3, ensuring the safety and stability of the cable 3 during the operation of the quay crane vehicle.

[0041] In some optional implementations, multiple groups of bayonet holes 621 are provided, and the multiple groups of bayonet holes 621 are distributed along the circumference of the edge of the locking disk 620. The multiple bayonet holes 621 can provide multi-point locking to enhance the locking effect.

[0042] In some optional embodiments, a flip cover 64 is provided on one side of the bottom shell 63, and the flip cover 64 is connected to the bottom shell 63 by a rotating shaft, and the flip cover 64 can be rotated along the rotating shaft and snapped at the opening of the bottom shell 63. The flip cover 64 is connected to the bottom shell 63 by the rotating shaft and can be opened and closed, thereby protecting the mechanical parts inside the bottom shell 63 and preventing dust and moisture from entering.

[0043] In some optional implementations, a fixing ring 50 is provided at the end of the hook 5 , and the traction rope 4 is connected to the hook 5 through the fixing ring 50 . The fixing ring 50 is used to connect the traction rope 4 to the hook 5 , so as to facilitate the adjustment of the tension of the cable 3 .

[0044] The above implementation method provides a specific structure and function implementation method of the cable reel locking device for the quay crane trolley, which can be adjusted and optimized according to actual needs.

[0045] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
