[0002] As an important windproof protection device for gantry cranes (hereinafter referred to as gantry cranes), windproof cables play an important role in fixing equipment in severe weather. Most of the windproof cables used in our gantry cranes are spiral buckle structures, which connect the gantry crane to the dock. In strong winds, the windproof cables give the crane a downward vertical force, which prevents the gantry crane from overturning or sliding.

[0003] The spiral buckle consists of a buckle ring, an adjusting screw with left and right threads, and a U-shaped buckle. Due to the influence of the production environment and the seaside moisture, the adjusting screw frequently got stuck, resulting in the inability to use the windproof cable normally. After on-site research and analysis, the main reason was that the meshing point between the adjusting screw and the buckle ring was not lubricated properly, and there was rust and wear, which eventually led to mechanical jamming. Summary of the invention

[0019] Embodiment 1

[0020] Reference Figure 1 and Figure 2The spiral buckle for windproof cable provided by the utility model comprises a buckle 1, an adjusting screw 2, a U-shaped buckle 3, a 1 / 8 hanging grease nipple 4 and a protective device. The buckle 1 has first threaded holes 11 penetrating therethrough at both ends, and is threadedly engaged with the adjusting screw 2 through the first threaded hole 11. The U-shaped buckle 3 is arranged at one end of the adjusting screw 2 away from the buckle 1. Oil passages 12 are respectively provided on the same side of the two ends of the buckle 1 where the adjusting screw 2 is threadedly engaged, and the oil passages 12 are connected with the first threaded hole 11. The buckle 1 has a second threaded hole 13 at one end of the oil passage 12 away from the first threaded hole 11; the second threaded hole 13 is connected with the oil passage 12 and passes through one side of the buckle 1. The 1 / 8 hanging grease nipple 4 is fixed to one side of the buckle 1 by engaging with the second threaded hole 13, and the flat end of the 1 / 8 hanging grease nipple 4 is located outside the buckle 1.

[0021] As can be seen from the above, the worker connects the 1 / 8 hanging grease nipple 4 through the grease gun and injects lithium-based grease. After the lithium-based grease passes through the 1 / 8 hanging grease nipple 4, it passes through the oil channel 12 and enters the meshing part of the buckle 1 and the adjusting screw 2. Then, with the help of the lubricating properties of the lithium-based grease and the pressure characteristics of the oil gun, on the one hand, by lubricating the surface of the adjusting screw 2, foreign matter such as dust in the thread can be squeezed out, which greatly improves the spiral fastening effect of the spiral buckle and enables the windproof zipper to fully play its windproof protection role. On the other hand, through regular lubrication and maintenance, the failure rate of the spiral buckle is greatly reduced, thereby increasing its service life.

[0022] The protective device is a nut 5, one side of which is welded to one side of the buckle 1. The 1 / 8 hanging grease fitting 4 is located in the through hole in the middle of the nut 5, and the height of the nut 5 is higher than the height of the 1 / 8 hanging grease fitting 4 located outside the buckle 1. The function of the nut 5 is to protect the 1 / 8 hanging grease fitting 4 from external impact.

[0023] The specific usage and function of this embodiment are as follows:

[0024] The utility model needs to implement manual on-site lubrication operation regularly. During the operation, a grease gun is connected to a 1 / 8 hanging grease nozzle 4, and lithium-based grease is injected into the meshing portion of the buckle ring 1 and the adjusting screw 2 by means of the grease gun for lubrication.

[0025] Embodiment 2

[0026] The difference between this embodiment and the first embodiment is that the structure of the protective device is different. Figure 3 and Figure 4 , the specific plan is as follows:

[0027] The protective device includes a protective sleeve 6, a dust cover 7, a hook rod 8 and a sleeve 9. One end of the protective sleeve 6 is welded to one side of the buckle 1. The 1 / 8 hanging grease nipple 4 is located in the protective sleeve 6, and the height of the protective sleeve 6 is higher than the height of the 1 / 8 hanging grease nipple 4 located outside the buckle 1. The function of the protective sleeve 6 is to protect the 1 / 8 hanging grease nipple 4 from external impact. The end of the protective sleeve 6 away from the buckle 1 is threadedly matched with a dust cover 7, and the dust cover 7 cooperates with the protective sleeve 6 to seal and protect the 1 / 8 hanging grease nipple 4, so as to prevent the 1 / 8 hanging grease nipple 4 from being blocked by dust, dirt, etc., and to increase its service life.

[0028] The dust cover 7 is rotatably fitted on the short rod end of the hook rod 8; the short rod end of the hook rod 8 passes through the center of the dust cover 7, and a first limit plate 81 is processed on both sides of the dust cover 7. One end of the sleeve 9 is welded to one side of the buckle 1, and the sleeve 9 is located on one side of the protective sleeve 6. The long rod end of the hook rod 8 extends into the sleeve 9 and is movably arranged in the sleeve 9; a limit ring 91 is processed on the end of the sleeve 9 away from the buckle 1, and a second limit plate 82 is processed on the end of the long rod end of the hook rod 8.

[0029] As can be seen from the above, when the dust cover 7 is tightened on the protective sleeve 6 or twisted off from the protective sleeve 6, the dust cover 7 will push the first limit plate 81, driving the hook rod 8 to move in parallel. When the dust cover 7 is twisted off from the protective sleeve 6, the long rod end of the hook rod 8 passes through the limiting cooperation of the second limit plate 82 and the limit ring 91, the hook rod 8 and the sleeve 9 will not separate, and the dust cover 7 will not detach from the spiral buckle, preventing the dust cover 7 from being lost after being removed during the lubrication operation of the spiral buckle. After the dust cover 7 is twisted off from the protective sleeve 6, the long rod end of the hook rod 8 rotates in the sleeve 9, driving the dust cover 7 to rotate around the long rod end of the hook rod 8, so that the dust cover 7 moves to a position outside the opening of the protective sleeve 6, avoiding position interference when the grease gun is connected to the 1 / 8 hanging grease nozzle 4.

[0030] The specific usage and function of this embodiment are as follows:

[0031] When the manual lubrication operation is performed in this embodiment, the dust cover 7 is first twisted off the protective sleeve 6, and then the dust cover 7 is rotated to a position outside the opening of the protective sleeve 6 by rotating the long rod end of the hook rod 8, and then the grease gun is connected to the 1 / 8 hanging grease nozzle 4, and lithium-based grease is injected into the meshing position of the buckle 1 and the adjusting screw 2 with the help of the grease gun for lubrication; after the lubrication is completed, the grease gun is removed from the 1 / 8 hanging grease nozzle 4, the dust cover 7 is rotated to the opening of the protective sleeve 6, and then the dust cover 7 is tightened on the protective sleeve 6 to complete the closure of the opening of the protective sleeve 6.

[0032] To sum up, compared with the prior art, the utility model reduces the probability of rust and wear of the spiral buckle by regularly implementing manual on-site lubrication operations, improves the service life of the spiral buckle and the spiral fastening effect, greatly reduces the failure rate, and at the same time, the service life of the spiral buckle is extended by an average of 30%, saving a lot of material costs, effectively ensuring the stability and reliability of the windproof cable, and is also suitable for various port lifting equipment using windproof cables.
