Description

Technical Field

[0001] This utility model relates to the technical field of cable limiting devices, and more specifically, to a cable limiting structure. Background Technology

[0002] Construction hoists are a commonly used piece of equipment in current engineering construction. Their structure is roughly as follows: Figure 1 As shown, the hoisting system uses a cage 1 to carry people and goods, which is transported vertically along the guide rail 2. It is mainly used for the construction and maintenance of high-rise buildings. During the operation of the cage 1, the cable moves up and down with the cage 1. When the cage 1 is moved to a high place, the cable is suspended in the air for a long time. Since the hoisting system is generally used outdoors, there is a possibility that the cable may be blown by strong winds and get caught on the building or scaffolding, thus posing a certain safety hazard. Utility Model Content

[0021] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0022] Example

[0023] Please refer to Figures 2-6 This embodiment provides a cable limiting structure, including a column 4, with multiple limiting plates 5 arranged vertically on the column 4, each limiting plate 5 having a limiting hole 6; the bottom limiting plate 5 is fixed to the column 4, and the remaining limiting plates 5 are slidably sleeved on the column 4 in the vertical direction; any two adjacent limiting plates 5 are connected by a limiting pull rope 7, and the top limiting plate 5 is provided with a connector 8.

[0024] In actual use, the top and bottom of the column 4 are fixed to one side of the guide rail frame 2 of the construction hoist. The column 4 is installed vertically, and the topmost limiting plate 5 is fixed to the cage 1 of the construction hoist via the connector 8. At the same time, the cable 3 of the construction hoist passes through the limiting holes 6 of each limiting plate 5. After installation, as shown... Figure 2 As shown. Thus, when the cage 1 moves upward, the cage 1 drives the top limit plate 5 to move upward, and at the same time drives the cable 3 to move upward.

[0025] Since adjacent limit plates 5 are connected by limit ropes 7, when the top limit plate 5 moves upward beyond the length of the limit rope 7, the second limit plate 5 from the top is pulled upward by the limit rope 7 and slides upward. Thus, regardless of the position the cage 1 moves upward, a corresponding number of limit plates 5 are pulled upward. At this time, the cable 3 is restricted by the limit holes 6 of each limit plate 5, resulting in a small swing distance in the air. This prevents the cable 3 from being blown by strong outdoor winds and getting caught on buildings or scaffolding, improving the safety of the cable 3 during use and reducing safety hazards.

[0026] like Figure 3 As shown, in some embodiments, the cross-section of the column 4 is polygonal, with the right side of the cross-section of the column 4 being arc-shaped. This can limit the movement of the limiting plate 5, restricting the limiting plate 5 to slide vertically along the column 4 and preventing it from rotating in the horizontal plane, thus facilitating the limiting of the cable 3.

[0027] like Figures 4-5 As shown, in some embodiments, the limiting plate 5 is provided with a winding assembly for winding the limiting pull rope 7. The winding assembly includes a storage box 9 disposed on the limiting plate 5 and a spring 10 disposed inside the storage box 9; a mounting shaft 11 is fixed inside the storage box 9, one inward end of the spring 10 is fixed to the mounting shaft 11, the top of the limiting pull rope 7 slides through the storage box 9 and is connected to the outward end of the spring 10, and the bottom of the limiting pull rope 7 is connected to the limiting plate 5 adjacent to it below.

[0028] When the cage 1 moves downwards, the limiting plates 5 slide downwards under gravity, at which point some of the limiting ropes 7 are in a relaxed state. This invention incorporates a winding assembly, so that when the limiting plates 5 move downwards, the spring 10 can retract the limiting ropes 7 into the storage box 9, preventing them from knotting or tangling when relaxed. When the limiting plates 5 move upwards, the lower limiting plate 5 pulls the limiting ropes 7 out of the storage box 9 for use, at which point the spring 10 is in a state of accumulating elasticity.

[0029] like Figures 2-6 As shown, in some embodiments, the column 4 is provided with a storage assembly for storing the cable 3. The storage assembly includes a storage box 12 for storing the cable 3, and the top of the storage box 12 has an inlet and outlet 13. A limiting plate 5 is located above the storage box 12. By providing this storage assembly, the cable 3 is placed inside the storage box 12 during installation, and the cable 3 passes through the inlet and outlet 13. Thus, when the cable 3 moves downwards, it can fall from the inlet and outlet 13 into the storage box 12 for storage.

[0030] Furthermore, unless otherwise explicitly specified or limited, the terms "installation" and "connection" in this application embodiment should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. The terms "upper," "lower," "left," "right," "inner," "outer," and "side," etc., are merely for reference to the direction in the accompanying drawings or the usual placement of the product during use. They are only for clearly describing this application and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limitations on this application. The terms "first," "second," etc., are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance; "multiple" refers to at least two. In this application embodiment, the limitations on relative positional relationships such as parallel, perpendicular, and aligned are all relative to the current technological level and are not absolutely strict limitations. Slight deviations are allowed; approximations of parallel, perpendicular, and aligned are all acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 degrees and 10 degrees.
