Description

Technical Field

[0001] The utility model belongs to the technical field of anti-overturning safety cables for cranes, and particularly relates to an installation structure of a lightweight anti-overturning safety cable for a crane. Background Technique

[0002] In order to adapt to the development trend of the large-scale of freight ships and improve their loading and unloading efficiency, port cranes are also constantly developing in the direction of large-scale. The large-scale of cranes also increases their center of gravity, windward area, and the possibility of suffering from wind disasters.

[0003] At present, the anti-typhoon and anti-hurricane devices adopted by large port cranes mainly include rail clamps, anchors (hooks), wheel stoppers, windproof wheel pins, windproof tie rods or cables, etc. And among these windproof methods, the windproof tie rod or cable is one of the most powerful and key devices in the anti-typhoon and anti-hurricane devices. Therefore, before a typhoon comes, large port cranes generally arrange two or more windproof cables at each corner of their gantries to ensure that the cranes have sufficient anti-typhoon ability.

[0004] However, the existing windproof cables have certain defects in actual use: since each set of the existing windproof cables usually consists of several shackles, one turnbuckle, and one windproof rope, the weight of each set is usually more than 150 kg, and the whole windproof cable is in a free state. When port workers need to pull the windproof cable to the anchoring position or non-anchoring position, it is very difficult to complete the operation by manual alone, which causes great inconvenience to the daily use of the owner. Content of the Utility Model

[0005] The technical problem solved by the utility model is to provide an installation structure of a lightweight anti-overturning safety cable for a crane, which can not only ensure the overall stability of the crane under storm conditions and prevent the whole machine from overturning, but also reduce the labor intensity of port workers, so that port workers can smoothly complete the normal connection and disassembly of the windproof cable alone.

[0006] To solve the above technical problems, the technical solution provided by the present utility model is as follows: a lightweight crane anti-overturning safety cable installation structure, which includes an upper windproof rope, a turnbuckle, and a lower windproof rope connected in sequence from top to bottom. The upper end of the upper windproof rope is connected to the crane. Connecting pieces one and two are respectively installed at the upper and lower ends of the turnbuckle, and both the connecting piece one and the connecting piece two are fixedly connected to the crane. At this time, since the present utility model relatively fixes the turnbuckle, the upper windproof rope and the crane together through the connecting piece one and the connecting piece two, only the lower windproof rope part in the present utility model is the movable part; in this way, in daily work, it only needs to remove the lower windproof rope and connect it to the anchor seat to complete the corresponding connection operation, so that the present utility model can control the weight of the movable part to less than 15 kg by reducing the movable part on the entire cable, and further enables a single person to smoothly complete the normal connection and disassembly of the windproof cable.

[0007] Further, one end of the connecting piece one is fixedly connected to the crane, and the other end of the connecting piece one is provided with a connecting hole one and is sleeved outside the pin shaft at the upper end of the turnbuckle through the connecting hole one; one end of the connecting piece two is fixedly connected to the crane, and the other end of the connecting piece two is provided with a connecting hole two and is sleeved outside the pin shaft at the lower end of the turnbuckle through the connecting hole two to realize the connection between the connecting piece one, the connecting piece two and the turnbuckle.

[0008] Further, the connecting hole one and the connecting hole two are elongated holes, and the length directions of the connecting hole one and the connecting hole two are both parallel to the length direction of the turnbuckle, and the widths of the connecting hole one and the connecting hole two are both larger than the diameters of the pin shafts at both ends of the turnbuckle to ensure that the turnbuckle can normally adjust its length.

[0009] Further, an upper shackle is connected to the end of the upper windproof rope far from the turnbuckle, and the upper shackle is connected to the ear plate on the crane, and the position of the ear plate can be flexibly selected according to the type of the crane.

[0010] Further, a lower shackle is connected to the end of the lower windproof rope far from the turnbuckle, and the lower shackle can be connected to the dock anchor seat to realize the corresponding anti-overturning function of the crane.

[0011] Further, the lightweight crane anti-overturning safety cable installation structure further includes a hook provided on the crane, and the lower shackle at the end of the lower windproof rope can be hooked to the hook to store the lower windproof rope in a non-working state.

[0012] As can be seen from the above technical solutions, the present utility model has the following advantages: Since the present utility model relatively fixes the turnbuckle, the upper windproof rope and the crane together through the first connecting piece and the second connecting piece, only the lower windproof rope part in the present utility model is the movable part, and in the daily work of the present utility model, it only needs to remove the lower windproof rope and connect it to the anchor seat to complete the corresponding connection operation, so that the present utility model can control the weight of the movable part below 15 kg by reducing the movable part on the entire cable, and thus a single person can smoothly complete the normal connection and disassembly of the windproof cable.

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0017] As Figure 1 shown, the present utility model provides a lightweight anti-overturning safety cable installation structure for a crane, which includes an upper windproof rope 2, a turnbuckle 4, and a lower windproof rope 6 connected in sequence from top to bottom.

[0018] Among them, one end of the upper windproof rope 2 far from the turnbuckle 4 is connected with an upper shackle 1, and is connected to the ear plate on the crane through the upper shackle 1. One end of the lower windproof rope 6 far from the turnbuckle 4 is connected with a lower shackle 9, and the lower shackle 9 can be connected to the dock anchor seat 8 in the working state to achieve the corresponding anti-overturning function of the crane, and the lower shackle 9 is hooked to the hook 7 provided on the crane in the non-working state to store the lower windproof rope 6 in the non-working state.

[0019] Both the upper and lower ends of the turnbuckle 4 are respectively installed with a first connecting piece 3 and a second connecting piece 5. One end of the first connecting piece 3 is fixedly connected to the crane. The other end of the first connecting piece 3 is provided with a first connecting hole and is sleeved outside the pin shaft at the upper end of the turnbuckle 4 through the first connecting hole. One end of the second connecting piece 5 is fixedly connected to the crane. The other end of the second connecting piece 5 is provided with a second connecting hole and is sleeved outside the pin shaft at the lower end of the turnbuckle 4 through the second connecting hole, so as to realize the connection between the first connecting piece 3, the second connecting piece 5 and the turnbuckle 4. Moreover, in order to ensure that the first connecting piece 3 and the second connecting piece 5 can adapt to the length adjustment of the turnbuckle 4, both the first connecting hole and the second connecting hole are elongated holes, and the length directions of the first connecting hole and the second connecting hole are both parallel to the length direction of the turnbuckle 4. The widths of the first connecting hole and the second connecting hole are both larger than the diameters of the pin shafts at both ends of the turnbuckle 4, so as to ensure that the pin shafts of the turnbuckle 4 can move relatively in the corresponding first connecting hole and second connecting hole, and further ensure that the turnbuckle 4 can normally adjust its length.

[0020] Based on this, since the present utility model relatively fixes the turnbuckle 4, the upper windproof rope 2 and the crane together through the first connecting piece 3 and the second connecting piece 5, only the lower windproof rope 6 part in the present utility model is the movable part. In this way, during daily work, only the lower windproof rope 6 needs to be removed and connected to the anchor seat to complete the corresponding connection operation, so that the present utility model can reduce the movable part on the entire cable, control the weight of the movable part to less than 15 kg, and further enable a single person to smoothly complete the normal connection and disassembly of the windproof cable.
