Description

Technical Field

[0001] The utility model belongs to the technical field of wire ropes, and particularly relates to a wire rope for the main luffing of a large-tonnage crawler crane. Background Art

[0002] The wire rope for the main luffing of a crane is an important component in a hoisting machine for controlling the swing of a boom. It is usually formed by twisting multiple strands of steel wires, has high strength and wear resistance, and can withstand large loads and frictional forces. The selection of a wire rope depends on the specific requirements of the crane, including factors such as the lifting weight, working environment, and required corrosion resistance. For example, for a crane that needs to work in a corrosive environment, a wire rope made of hot-dip galvanized or stainless steel may be selected. Therefore, it can be seen that the existing wire ropes basically meet people's usage requirements, but there are still the following problems.

[0003] When an operator uses a wire rope, since the wire rope is formed by winding several groups of strand wires, and since there may be no protective sleeve around the general wire rope, after long-term use of the wire rope, rust may occur on the surface of the wire rope. When rust appears on the surface of the wire rope, it may affect the use of the wire rope. For this reason, we propose a wire rope for the main luffing of a large-tonnage crawler crane. Content of the Utility Model

[0004] The utility model provides a wire rope for the main luffing of a large-tonnage crawler crane. By sleeving a wear-resistant layer and a braided layer on the surfaces of a rubber ring and a main line, the braided layer and the wear-resistant layer protect the rubber ring and the main line, preventing rust from occurring on the wire rope after long-term use and improving the service life of the wire rope.

[0005] To achieve the above object, the utility model provides the following technical solution: A wire rope for the main luffing of a large-tonnage crawler crane, including a main line, a foam rubber is attached to the surface of the main line, and several groups of sub-wire groups are pasted on the surface of the foam rubber. A braided layer is wrapped around the surface of the sub-wire group, and a wear-resistant layer is wrapped around the surface of the braided layer.

[0006] Further, the sub-wire group includes a sub-line and a rubber ring. The rubber ring is attached to the surface of the foam rubber, and the sub-line is wound around inside the rubber ring.

[0007] Further, support blocks are filled between the inside of the rubber ring and the surface of the sub-line.

[0008] Further, the gap between the rubber ring and the braided layer is filled with a filling material.

[0009] Further, several groups of relief grooves are formed on the surface of the wear-resistant layer.

[0010] The beneficial effects of the utility model are:

[0011] 1. The steel wire rope for the main luffing of the large-tonnage crawler crane is provided with a braided layer and a wear-resistant layer. The braided layer and the wear-resistant layer are respectively wound around the rubber ring and the main line surface. The wear-resistant layer increases the friction between the steel wire rope and the object surface, improves the friction on the surface of the steel wire rope, and the braided layer is braided and wound around the rubber ring and the main line surface, increasing the strength of the steel wire rope surface and improving the sealing performance, avoiding rust on the steel wire rope after being eroded by rainwater.

[0012] 2. The steel wire rope for the main luffing of the large-tonnage crawler crane is provided with foam glue and filler. The main line and the rubber ring are bonded together by the foam glue, increasing the stability of the rubber ring wound around the main line surface. And filler is filled between the rubber ring and the braided layer to fill the gap between the braided layer and the rubber ring, improving the stability of the braided layer wound around the rubber ring surface.

[0016] In order to further understand the content, features and effects of the present utility model, the following embodiments are hereby exemplified and described in detail in conjunction with the drawings.

[0017] Embodiment:

[0018] Please refer to Figure 1 - Figure 2, the steel wire rope for the main luffing of large-tonnage crawler cranes, including the main line 1, a foam rubber 5 is attached to the surface of the main line 1, and several groups of auxiliary wire groups are pasted on the surface of the foam rubber 5. The auxiliary wire group includes an auxiliary line 2 and a rubber ring 4. The rubber ring 4 is attached to the surface of the foam rubber 5, and the auxiliary line 2 is wound around inside the rubber ring 4. The surface of the auxiliary wire group is wrapped with a braided layer 8, and the surface of the braided layer 8 is wrapped with a wear-resistant layer 7. When the operator uses this cable, the operator first winds the support blocks 3 together, then the operator applies the foam rubber 5 on the surface of the main line 1, and then the operator winds the rubber ring 4 on the surface of the main line 1 and pastes the rubber ring 4 on the surface of the main line 1 through the foam rubber 5 to increase the stability of the rubber ring 4 wound around the main line 1. Subsequently, the operator winds the braided layer 8 on the surface of the rubber ring 4 and wraps the wear-resistant layer 7 on the surface of the braided layer 8. By wrapping the braided layer 8 and the wear-resistant layer 7 on the surface of the rubber ring 4 in sequence, the wear resistance of the steel wire rope during use is increased.

[0019] In other embodiments, support blocks 3 are filled between the inside of the rubber ring 4 and the surface of the auxiliary line 2. By adding support blocks 3 to the gap between the auxiliary line 2 and the rubber ring 4, the support blocks 3 support the auxiliary line 2 and the rubber ring 4, preventing the rubber ring 4 from forming a downward groove and increasing the stability of the rubber ring 4 wound around the surface of the main line 1.

[0020] In other embodiments, a filler 9 is filled in the gap between the rubber ring 4 and the braided layer 8. By adding the filler 9 between the rubber ring 4 and the braided layer 8, the filler 9 increases the front end of the space at the gap where the braided layer 8 is sleeved on the surface of the rubber ring 4, preventing the braided layer 8 from sagging downward due to the gap between the rubber ring 4 and the braided layer 8 during long-term use.

[0021] In other embodiments, several groups of relief grooves 6 are formed on the surface of the wear-resistant layer 7. By forming several groups of relief grooves 6 on the surface of the wear-resistant layer 7, grooves are formed on the surface of the wear-resistant layer 7, making the surface of the wear-resistant layer 7 uneven. By the uneven surface of the wear-resistant layer 7, the friction force of the wear-resistant layer 7 during use is increased.

[0022] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
