Description

Technical Field

[0001] This utility model relates to the field of port yard crane maintenance technology, and in particular to a tooling for replacing and fixing the hoisting wire rope of a yard crane. Background Technology

[0002] The hoisting mechanism of a container terminal is a core piece of operational equipment, and its reliability directly impacts port operational efficiency. The hoisting wire rope, as a critical load-bearing component, endures dynamic loads and environmental corrosion over extended periods, with an average service life of approximately one year (60,000-100,000 TEUs of cargo handled). Currently, several port areas have over several hundred container terminals, and it is estimated that several hundred more will require replacement of their hoisting wire ropes annually. During the replacement process, due to the nature of the process, the two ends of the new wire rope and the old wire rope must be welded to the ground. The old wire rope is then unloaded by rotating a drum to wind the new rope, which is then wound onto the drum for reuse. This process, due to factors such as the weight of the wire rope and operational safety requirements, necessitates multiple tightening and loosening of the wire rope to complete the replacement. In existing technologies, the steel wire rope is usually secured by a chain during the fixing and loosening process. However, this method has several problems: First, the friction between the chain and the oil-coated steel wire rope is insufficient, posing a risk of slippage. Second, the chain needs to be struck when releasing the fixation, which not only affects work efficiency but may also damage the steel wire rope and chain, increasing safety risks.

Figure 2 This schematic diagram shows a side view of a tooling for replacing and fixing the hoisting wire rope of a yard bridge according to one embodiment of the present invention. Figure 3 This is a schematic top view of a tooling for replacing and securing the hoisting wire rope of a yard crane according to one embodiment of the present invention. Figures 1-3 As shown, in this embodiment, the tooling for replacing and fixing the hoisting wire rope of the yard crane includes:

[0035] Wire rope clamping structure 1 is used to clamp onto the hoisting wire rope of the yard bridge;

[0036] The locking structure 2 is detachably connected to the wire rope clamping structure 1, and locks the wire rope clamping structure 1 onto the hoisting wire rope of the yard bridge.

[0037] The adapter structure 3 is fixedly connected to the wire rope clamping structure 1 and is used to connect the pre-set fixed position of the hoisting mechanism of the yard bridge, so as to maintain the position and posture of the wire rope clamping structure 1 and the hoisting wire rope of the yard bridge connected to the wire rope clamping structure 1.

[0038] Furthermore, according to one embodiment of the present invention, the wire rope clamping structure 1 includes: a first clamping sleeve 4 and a second clamping sleeve 5;

[0039] Both the first card sleeve 4 and the second card sleeve 5 are provided with a semi-circular groove 6;

[0040] The first card sleeve 4 and the second card sleeve 5 are arranged opposite to each other, and one side of the first card sleeve 4 is hinged to the corresponding side of the second card sleeve 5 by a hinge structure 17. The other side of the first card sleeve 4 and the corresponding other side of the second card sleeve 5 are respectively provided with mutually cooperating connection structures 7.

[0041] The locking structure 2, through its connection with the connecting structure 7, locks the first clamping sleeve 4 and the second clamping sleeve 5 onto the hoisting wire rope of the yard bridge. This arrangement allows the first clamping sleeve 4 and the second clamping sleeve 5 to form a structure where one side is always connected, while the other side can be opened and closed as needed. This makes it more convenient and faster to clamp the wire rope using the first clamping sleeve 4 and the second clamping sleeve 5 through the cylindrical cavity formed by the two semi-circular grooves 6, effectively shortening the time required for wire rope replacement and fixing.

[0042] Furthermore, according to one embodiment of the present invention, the connecting structure 7 includes: a mounting platform 8 and a locking platform 9;

[0043] Mounting platform 8 is located on the outer wall of the other side of the second card sleeve 5, and card holder 9 is located on the outer wall of the other side of the first card sleeve 4;

[0044] The mounting platform 8 has a mounting groove 10, and the clamping platform 9 has a clamping slot 11. The mounting groove 10 and the clamping slot 11 are arranged opposite each other. When the other side of the first clamping sleeve 4 and the other side of the second clamping sleeve 5 are aligned and abutted, the mounting groove 10 and the clamping slot 11 are aligned and connected. This arrangement ensures that when the first clamping sleeve 4 and the second clamping sleeve 5 are installed on the wire rope and fastened and aligned, the mounting groove 10 and the clamping slot 11 are perfectly aligned. This, in conjunction with the locking structure 2, clamps the wire rope, thereby ensuring that the first clamping sleeve 4 and the second clamping sleeve 5 are stably and securely positioned on the wire rope and will not slip due to external force, thus ensuring the efficiency of wire rope replacement.

[0045] Furthermore, according to one embodiment of the present invention, the locking structure 2 includes: a pin 12, a screw 13, and a force-applying rod 14;

[0046] One end of pin 12 ( Figure 2 The lower middle end can be flipped and installed in the mounting slot 10, while the other end ( Figure 2 The upper middle part is provided with external threads;

[0047] One end of the screw 13 is provided with an internal thread, which is screwed to the other end of the pin 12, and the outer wall of this end is tapered. After this end is screwed to the pin 12, it is snapped into the side of the slot 11 away from the mounting slot 10.

[0048] The force-applying rod 14 is located at the other end of the screw 13. This arrangement allows the first and second ferrules 4 and 5 to be engaged with the wire rope, aligning and connecting the mounting groove 10 and the slot 11. By flipping the pin 12, the pin 12 can be positioned simultaneously in both the mounting groove 10 and the slot 11. Simultaneously, due to the connection between the screw 13 and the pin 12, the screw 13 can be flipped together with the pin 12, positioning itself just above the slot 11. At this point, rotating the screw 13 via the force-applying rod 14, through the screwed connection between the screw 13 and the pin 12, causes the screw 13 to press downwards into the slot 11. This causes the clamping platform 9 and the mounting platform 8 to press against each other, thus clamping the first and second ferrules 4 and 5 tightly onto the wire rope, ensuring a stable and secure position for both ferrules 4 and 5, preventing slippage.

[0049] Furthermore, according to one embodiment of the present invention, the adapter structure 3 includes: a fixing plate 15 and a hanging lug 16;

[0050] The fixing plate 15 is welded to the outer walls of both sides of the second ferrule 5;

[0051] The lug 16 has a U-shaped structure, with each end fixedly connected to a fixing plate 15. This design allows the lug 16 to be secured by the fixing plates 15, and connects to other external structures (such as other wire ropes) to stabilize the position and orientation of the lug, thereby stabilizing the position and orientation of the entire fixture and preventing displacement or slippage. Furthermore, the fixture's clamping of the wire rope ensures its fixed position. Moreover, this design allows for quick release of the wire rope without damaging it, thus avoiding safety risks.

[0052] Furthermore, according to one embodiment of this utility model, the end of the hook 16 furthest from the second sleeve 5 is inclined in the direction opposite to the horizontal projection of the first sleeve 4. This arrangement allows for a certain gap between the hook 16 and the wire rope clamped by the wire rope clamping structure 1 when connecting to other external structures, ensuring that the wire rope is not affected, the process of fixing and releasing the wire rope is undisturbed, and effectively avoiding safety risks.

[0053] Furthermore, according to one embodiment of this utility model, the lug is made of Q355B alloy steel; the pin 12 is made of 304 stainless steel; and the first ferrule 4 and the second ferrule 5 are made of 45# steel.

[0054] According to the above-described solution of this utility model, the present utility model can achieve the following beneficial effects:

[0055] Improved safety: This utility model fixture fixes the steel wire rope through a semi-circular groove, effectively avoiding the risk of slippage when fixing the chain, eliminating safety accidents caused by slippage of the fixed end, and ensuring the personal safety of the operators.

[0056] Improved work efficiency: Compared with the traditional chain fixing method, this tooling is more convenient to operate, and the speed of fixing and releasing the wire rope is faster, which greatly shortens the time for wire rope replacement and improves the maintenance efficiency of the yard crane lifting mechanism.

[0057] Reduced labor intensity: It reduces the workload of maintenance personnel, eliminating the need for multiple tools and allowing a single person to easily complete the fixing and disassembly of the wire rope.

[0058] Cost reduction: It reduces labor and material consumption costs. Work that previously required many tools can now be easily disassembled and fixed using the tooling of this utility model, thus improving the economy of maintenance work.

[0059] Protective Equipment: During the fixing and releasing of the wire rope, no damage is caused to the surface of the wire rope, extending its service life. At the same time, it ensures the overall reliability and safety of the crane, reducing equipment failure rate and company labor costs.

[0060] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
