Description

Technical Field

[0001] The utility model belongs to the technical field of wire rope connection of a large overhead crane, and in particular relates to a wire rope connection device for a large overhead crane. Background Art

[0002] During the replacement of the wire rope of a large overhead crane, the traditional docking method requires multiple personnel to manually hold the two sections of the wire rope to be connected for welding, which wastes manpower. At the same time, due to the large diameter and heavy weight of the large wire rope, safety accidents are prone to occur during the manual welding process. In addition, due to the uneven joint interface of the wire rope during welding, the welding time is long and the welding is not firm, which is very likely to cause a breakage accident during the replacement process, affecting the work efficiency. Summary of the invention

[0003] The utility model aims to provide a wire rope guiding device for a large overhead crane to solve the problems existing in the prior art.

[0004] The utility model solves the technical problem by adopting a technical solution: a wire rope guiding device for a large overhead crane comprises a connecting ring, wherein the connecting ring has two connecting rings, one side of the connecting ring is provided with a notch, and the notch end of the connecting ring is detachably hinged with an arc-shaped docking block.

[0005] Furthermore, ear plates are symmetrically welded on the outer walls on both sides of the notch end of the connecting ring, the other end of the ear plate is arc-shaped, and a through hole is provided on the ear plate.

[0006] Furthermore, the arc-shaped docking block is arc-shaped, a hinge plate is welded on the outer wall of the arc-shaped docking block, one end of the hinge plate is arc-shaped, a through hole is arranged on the hinge plate, and the arc-shaped end of the hinge plate is inserted between the two ear plates.

[0007] Furthermore, the through holes of the hinged plate and the through holes of the two ear plates are connected with a bolt pair, and the connecting ring and the arc-shaped docking block are hinged through the ear plates, the hinged plate and the bolt pair.

[0008] Furthermore, at least one steel wire rope is hung between the two connecting rings.

[0009] Furthermore, the two connecting rings are connected to each other.

[0010] The utility model has the following beneficial effects:

[0011] 1. The utility model can firmly butt-weld steel wire ropes without holding heavy steel wire ropes for a long time for butt welding, thereby preventing breakage during the replacement process and improving work efficiency.

[0012] 2. The arc design of the arc-shaped docking block can better weld the rope end of the wire rope to the arc-shaped docking block, thereby shortening the welding time and ensuring the firmness of the welding.

[0013] 3. The arc-shaped docking block and the connecting ring are hinged, and the connection angle can be changed to adapt to the movement trajectory during traction. For example, it can bend along with the circular pulley to prevent excessive bending and breakage.

[0014] 4. A notch is provided on one side of the connecting ring, so that the wire rope can be hung or another connecting ring can be directly hung. There is no need to disassemble, hang and lock the wire rope, and there is no need to weld the two connecting rings, thereby improving work efficiency and enabling the utility model to be reused.

[0019] The utility model will now be further described in detail with reference to the accompanying drawings.

[0020] Embodiment 1:

[0021] like Figure 1-2 As shown, a wire rope guiding device for a large overhead crane comprises a connecting ring 1. The connecting ring 1 has two connecting rings. A notch 2 is provided on one side of the connecting ring 1. An arc-shaped docking block 3 is detachably hinged at the end of the notch 2 of the connecting ring 1.

[0022] The outer walls of the two sides of the notch 2 of the connecting ring 1 are symmetrically welded with ear plates 4, the other end of the ear plates 4 is arc-shaped, and a through hole 5 is provided on the ear plates 4. The notch 2 can be used to hang a wire rope 9, or two connecting rings 1 can be hung together.

[0023] The arc-shaped docking block 3 is arc-shaped, and a hinge plate 6 is welded on the outer wall of the arc-shaped docking block 3 . One end of the hinge plate 6 is arc-shaped, and a through hole 7 is provided on the hinge plate 6 . The arc-shaped end of the hinge plate 6 is inserted between the two ear plates 4 .

[0024] The arc-shaped design of the arc-shaped butt joint block 3 can better weld the rope end of the wire rope to the arc-shaped butt joint block 3, thereby shortening the welding time and ensuring the firmness of the welding.

[0025] The through hole 7 of the hinge plate 6 and the through holes 5 of the two ear plates 4 are connected with a bolt pair 8 , and the connecting ring 1 and the arc-shaped docking block 3 are hinged through the ear plates 4 , the hinge plate 6 and the bolt pair 8 .

[0026] At least one wire rope 9 is hung between the two connecting rings 1. The number of wire ropes 9 is determined according to the load-bearing weight of the wire ropes 9. If the wire ropes 9 are thin and insufficient to bear the tension between the traveling pulley blocks, the number of wire ropes 9 is increased until the requirements are met.

[0027] This embodiment provides a use of the utility model. When the rope ends of the new and old wire ropes are far apart and it is difficult to hold the wire rope, the two connecting rings 1 can be connected by a wire rope 9, and then the overhead crane is started to pull the new wire rope into place to complete the replacement.

[0028] Embodiment 2:

[0029] like Figure 3 As shown, a wire rope guiding device for a large overhead crane comprises a connecting ring 1. The connecting ring 1 has two connecting rings. A notch 2 is provided on one side of the connecting ring 1. An arc-shaped docking block 3 is detachably hinged at the end of the notch 2 of the connecting ring 1.

[0030] The outer walls of the two sides of the notch 2 of the connecting ring 1 are symmetrically welded with ear plates 4, the other end of the ear plates 4 is arc-shaped, and a through hole 5 is provided on the ear plates 4. The notch 2 can be used to hang a wire rope 9, or two connecting rings 1 can be hung together.

[0031] The arc-shaped docking block 3 is arc-shaped, and a hinge plate 6 is welded on the outer wall of the arc-shaped docking block 3 . One end of the hinge plate 6 is arc-shaped, and a through hole 7 is provided on the hinge plate 6 . The arc-shaped end of the hinge plate 6 is inserted between the two ear plates 4 .

[0032] The arc-shaped design of the arc-shaped butt joint block 3 can better weld the rope end of the wire rope to the arc-shaped butt joint block 3, thereby shortening the welding time and ensuring the firmness of the welding.

[0033] The through holes 7 of the hinged plate 6 and the through holes 5 of the two ear plates 4 are connected with a pair of bolts 8 , and the connecting ring 1 and the arc-shaped docking block 3 are hingedly connected through the ear plates 4 , the hinged plate 6 and the pair of bolts 8 .

[0034] The two connecting rings 1 are connected to each other.

[0035] This embodiment provides a use of the utility model. When the rope ends of the new and old steel wire ropes are close to each other and it is easy to connect the two rope ends, the two connecting rings 1 can be directly hung, and then the overhead crane is started to pull the new steel wire rope into place to complete the replacement.

[0036] The working principle of the utility model is:

[0037] When in use, the rope ends of the new and old steel wire ropes are welded to the two arc-shaped docking blocks 3 respectively. Since the arc-shaped docking blocks 3 are arc-shaped, the rope ends of the steel wire ropes can be better welded to the arc-shaped docking blocks 3, thereby shortening the welding time and ensuring the firmness of the welding.

[0038] After welding, if the ends of the new and old steel wire ropes are far apart and it is difficult to hold the steel wire rope, such as when the end of the old steel wire rope is suspended and the end of the new steel wire rope is on the ground, it is necessary to lift the new steel wire rope high when directly connecting them, which is difficult. At this time, two ends of a sufficiently long steel wire rope 9 are hung from the notch 2 to connect two connecting rings 1. The number of steel wire ropes 9 depends on the load-bearing weight of the steel wire rope 9. If the steel wire rope 9 is thin and is not enough to bear the tension between the crane pulley blocks, the number of steel wire ropes 9 is increased until the requirements are met.

[0039] If the rope ends of the new and old steel wire ropes are close to each other, it is easy to connect the two rope ends. For example, the rope ends of the new and old steel wire ropes are both located on the ground and are very close to each other. At this time, one connecting ring 1 is passed through the notch 2 of the other connecting ring 1, so that the two connecting rings 1 are directly hung. After hanging, the hinged plate 6 is inserted between the two ear plates 4 of the corresponding connecting ring 1, and the bolt pair 8 is inserted into the through hole 5 and the through hole 7 and bolted, thereby completing the connection between the connecting ring 1 and the arc-shaped connecting block.

[0040] Then start the crane to pull the new steel wire rope, and the old steel wire rope pulls the new steel wire rope to put the new steel wire rope in place. After the new steel wire rope is in place, the rope ends of the new and old steel wire ropes are cut off by a cutting machine, and then the subsequent fixing operation of the new steel wire rope is performed to complete the replacement. The rope ends on the arc-shaped connecting block are polished clean with a polishing tool, so that the utility model can be reused.

[0041] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention shall fall within the scope of protection of the present invention.

[0042] The technology, shape and structure parts not described in detail in the present invention are all known technologies.
