Description

Technical Field

[0001] This utility model belongs to the field of crane safety protection technology, and in particular relates to an anti-wear isolation device for overhead crane wire ropes. Background Technology

[0002] In the field of heavy-duty bridge cranes, 310T overhead cranes, as core equipment in industries such as metallurgy and shipbuilding, have long been plagued by abnormal wear between the wire ropes and balance beams in their main hoisting system. Statistics show that wire rope and balance beam wear-related fractures account for 34.7% of major overhead crane accidents. Especially in the high-temperature, high-dust conditions of steel mills, the main hoisting wire ropes of 310T overhead cranes, due to frequent oblique loads, have an average lifespan of only 60% of that under normal operating conditions, with annual replacement costs exceeding 120,000 yuan per unit. Utility Model Content

[0003] This invention addresses the problem of wire rope breakage due to wear between the wire rope and the balance beam in heavy-duty bridge cranes. It provides a wire rope anti-wear isolation device to prevent the wire rope from slipping into the balance beam and causing wear.

[0004] The technical solution adopted by this utility model for an anti-wear isolation device for overhead crane wire ropes is as follows:

[0005] A wear-resistant isolation device for overhead crane wire ropes includes a barrier structure installed on the overhead crane balance beam via a connecting structure. The barrier structure is continuously arranged around the passage area of ​​the wire rope on the balance beam, and the barrier structure forms a three-dimensional isolation barrier larger than the diameter of the wire rope.

[0006] A further improvement of this utility model is that the enclosure structure is welded from multiple closed rectangular cross-section pipes, and the cross-sectional dimensions of each closed rectangular cross-section pipe are 40-60mm×40-60mm.

[0007] A further improvement of this utility model is that the vertical distance between the inner edge of the enclosure structure and the edge of the balance beam is ≤2mm.

[0008] A further improvement of this utility model is that the inner wall of the enclosure structure is provided with a wear indicator layer made of red anti-rust paint.

[0009] A further improvement of the present invention is that the connecting structure includes a connecting pipe located between the enclosure structure and the balance beam, and the two ends of the connecting pipe are respectively connected to the enclosure structure and the balance beam.

[0010] A further improvement of this utility model is that the two ends of the connecting pipe are respectively welded to the enclosure structure and the balance beam.

[0011] A further improvement of this utility model is that the two ends of the connecting pipe are detachably connected to the enclosure structure and the balance beam, respectively.

[0012] A further improvement of this utility model is that: both the enclosure structure and the balance beam are provided with connecting rods adapted to the connecting pipes, the connecting rods on the enclosure structure extend downwards, and the connecting rods on the balance beam extend upwards.

[0013] A further improvement of this utility model is that: the end of the connecting rod is provided with an elastic protrusion made of spring steel, and both ends of the connecting tube are provided with connecting grooves that are adapted to the elastic protrusion.

[0014] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows:

[0015] In this invention, the enclosure structure restricts the horizontal movement of the wire rope within the enclosure structure. Since the vertical distance between the inner edge of the enclosure structure and the edge of the balance beam is ≤2mm, friction between the wire rope and the balance beam is prevented when the wire rope moves within the enclosure structure.

[0016] In this invention, the wear indicator layer is set on the inner wall of the enclosure structure. Therefore, when red anti-rust paint appears on the wire rope, it indicates that the wire rope has worn through the side wall of the enclosure structure, which can remind maintenance personnel that the enclosure structure needs to be replaced as soon as possible. At the same time, maintenance personnel only need to check whether red anti-rust paint appears on the wire rope to determine whether the enclosure structure needs to be replaced, without the need for maintenance personnel to frequently inspect the enclosure structure, making it convenient to use.

[0017] In this invention, when the two ends of the connecting pipe are detachably connected to the enclosure structure and the balance beam respectively, it is convenient to disassemble and replace the damaged enclosure structure. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. In the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concept of this utility model.

[0023] First refer to Figure 1 and Figure 2 As can be seen, this utility model includes a fencing structure 1, which is installed above the balance beam 3 via a connecting structure 4. The fencing structure 1 is welded from multiple closed rectangular cross-section pipes, specifically multiples of 4 such as 4 or 8, with each pipe having a cross-sectional dimension of 40-60mm × 40-60mm. These multiple closed rectangular cross-section pipes are continuously arranged around the perimeter of the passage area of ​​the steel wire rope 2 on the balance beam 3, thus forming a three-dimensional isolation barrier larger than the diameter of the steel wire rope 2. In this utility model, the vertical distance between the inner edge of the fencing structure 1 and the edge of the balance beam 3 is ≤2mm.

[0024] The aforementioned connection structure 4 includes a connecting pipe 41 located between the enclosure structure 1 and the balance beam 3, and both ends of the connecting pipe 41 are connected to the enclosure structure 1 and the balance beam 3 respectively.

[0025] Example 1

[0026] In this embodiment, the two ends of the connecting pipe 41 are fixedly welded to the enclosure structure 1 and the balance beam 3, respectively.

[0027] Example 2

[0028] In this embodiment, both ends of the connecting pipe 41 are detachably connected to the enclosure structure 1 and the balance beam 3, respectively. Specifically, as shown... Figure 2 As shown, the enclosure structure 1 is fixedly welded with a downwardly extending connecting rod 42, and the edge of the balance beam 3 is fixedly welded with an upwardly extending connecting rod 42 corresponding to the position of the connecting rod 42 of the enclosure structure 1. At the same time, the bottom end of the connecting rod 42 welded to the enclosure structure 1 and the bottom end of the connecting rod 42 welded to the edge of the balance beam 3 are both fixedly welded with elastic protrusions 43, each elastic protrusion 43 being made of spring steel.

[0029] To facilitate the detachable connection of the connecting pipe 41 with the enclosure structure 1 and the balance beam 3, connecting grooves 44 adapted to the elastic protrusions 43 are respectively provided at both ends of the connecting pipe 41.

[0030] Example 3

[0031] Based on Embodiment 1 or Embodiment 2, this embodiment has a wear indicator layer coated on the inner wall of the closed rectangular cross-section pipe of the enclosure structure 1. The wear indicator layer is made of red anti-rust paint.

[0032] In the above embodiments, this utility model provides a wear-resistant isolation device for overhead crane wire ropes. The enclosure structure in this utility model restricts the horizontal movement of the wire rope within the enclosure structure. Since the vertical distance between the inner edge of the enclosure structure and the edge of the balance beam is ≤2mm, friction between the wire rope and the balance beam is prevented when the wire rope moves within the enclosure structure. The wear indicator layer in this utility model is located on the inner wall of the enclosure structure. Therefore, when red anti-rust paint appears on the wire rope, it indicates that the wire rope has worn through the side wall of the enclosure structure, prompting maintenance personnel to replace the enclosure structure as soon as possible. Furthermore, maintenance personnel only need to check for red anti-rust paint on the wire rope to determine whether the enclosure structure needs replacement, eliminating the need for frequent inspections and making it convenient to use. When the two ends of the connecting pipe are detachably connected to the enclosure structure and the balance beam respectively, it facilitates the disassembly and replacement of the damaged enclosure structure.
