Description

Technical Field

[0001] The utility model relates to the technical field of construction hoists, and particularly relates to a cable guiding device for a construction hoist. Background Art

[0002] For existing public buildings and residences, vertical transportation equipment is essential, mostly construction hoists or construction elevators. The trailing cable of the cage will extend or retract from the lower cable drum as the cage ascends or descends. However, due to the limited width of the upper opening of the cable drum and the relatively large wind load at high altitudes, if the cable exposed in the air sways greatly under the influence of the wind load, there will be certain potential safety hazards. Content of the Utility Model

[0003] The purpose of the utility model is to solve the above problems in the prior art and provide a cable guiding device for a construction hoist.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A cable guiding device for a construction hoist includes an extension body and a plurality of vertically corresponding limiting rings with notches; the extension body carries the trailing cable and ascends and descends with the cage of the hoist; elastic bodies are connected to both sides of the notch of the limiting ring, and the ends of the elastic bodies on both sides are in contact; a support ring corresponding to the elastic body vertically is arranged at the end of the extension body, and the trailing cable passes through the support ring.

[0006] Further, an installation seat is arranged inside the notch of the limiting ring, and the elastic body is connected to the installation seat through a bolt.

[0007] Further, a support pipe is connected to one side of the limiting ring, and the support pipe is connected to the pipe body fixed at the construction site through a fastener.

[0008] Further, a mounting plate is connected to one end of the extension body, and the mounting plate is connected to the outside of the cage of the hoist through a bolt.

[0009] Further, through holes for the trailing cable to pass through are arranged on the mounting plate.

[0010] Further, a wire clamping structure for clamping the trailing cable is arranged on the outside of the extension body.

[0011] Further, the wire clamping structure includes two plate bodies clamping both sides of the trailing cable, and the two plate bodies are connected through a bolt, and one of the plate bodies is connected to the extension body.

[0012] Further, the support ring surrounds the extension body, and both the upper and lower ends of the support ring are set to be conical.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model can expand the elastic body in two directions through the support ring. During the process of the lift cage driving the trailing cable to lift and lower, the trailing cable can smoothly enter or leave the limit ring; when the elastic body is not subject to external force, it forms a closed state with the limit ring to limit the swing of the trailing cable, avoiding potential safety hazards caused by large swings of the trailing cable; the lateral offset of the trailing cable is limited, which facilitates the trailing cable to smoothly enter the cable drum when it falls.

[0015] The elastic body of the utility model is connected to the limit ring through bolts and mounting seats, which is convenient for disassembly and replacement; the limit ring is supported by a support pipe and a fastener. By adjusting the relative position of the fastener and the support pipe, the distance between the limit ring and the trailing cable to the outer wall can be adjusted; both the upper and lower ends of the support ring are conical, which is convenient for expanding the elastic body.

[0024] The following further describes the present utility model in detail with reference to embodiments.

[0025] Specific embodiments of the cable guiding device for a construction hoist provided by the present utility model:

[0026] Please refer to Figures 1-4 , a cable guiding device for a construction hoist, including an extension body 1. The extension body 1 carries a trailing cable 11 and ascends and descends with the cage of the hoist; one end of the extension body 1 is connected with a mounting plate 8, and the mounting plate 8 is connected to the outside of the cage of the hoist by bolts; a support ring 2 is provided on the outside of the other end of the extension body 1. In this embodiment, the support ring 2 is formed by bending a plate-shaped structure into a ring and welding. The support ring 2 surrounds the extension body 1 and is welded to the extension body 1.

[0027] In this embodiment, the extension body 1 is horizontally arranged; a through hole 10 for the trailing cable 11 to pass through is provided in the upper part of the mounting plate 8. The upper end of the trailing cable 11 passes through the through hole 10 and extends into the cage to supply power to the electrical equipment on the cage; the part of the trailing cable 11 passing through the through hole 10 and extending out is laid along the upper side of the extension body 1, passes through the upper part of the support ring 2, and then reaches the outside of the end of the extension body 1 and bends downward to form a vertically suspended section.

[0028] A wire clamping structure 9 for clamping the trailing cable 11 is provided on the outside of the extension body 1; the wire clamping structure 9 includes two plate bodies clamping both sides of the trailing cable 11, and the two plate bodies are connected by bolts, and one of the plate bodies is connected to the extension body 1 by welding. In this embodiment, two wire clamping structures 9 are provided. One of the wire clamping structures 9 is located on the upper side of the extension body 1 between the mounting plate 8 and the support ring 2; the other wire clamping structure 9 is located at the end of the extension body 1 and acts on the upper end of the vertically suspended section of the trailing cable 11; the extension body 1 drives the trailing cable 11 to ascend and descend through the wire clamping structure 9.

[0029] The lower part of the trailing cable 11 is stored in a cable drum (not shown in the figure). As the cage ascends, the trailing cable 11 extends out of the cable drum; as the cage descends, the trailing cable 11 falls into the cable drum. When the cage ascends to a relatively high height, the distance that the trailing cable 11 hangs in the air is relatively long, and it sways with the wind, posing a greater safety hazard. For example, the trailing cable 11 may get caught somewhere, resulting in the inability to retract or extend the trailing cable 11, and the swinging range of the trailing cable 11 is large and it cannot fall into the cable drum.

[0030] Therefore, a number of vertically corresponding limiting rings 3 with notches are provided; the limiting rings 3 are used for the trailing cable 11 to pass through when ascending and descending, to achieve lateral limitation of the trailing cable 11, restrict the swaying of the trailing cable 11, and thus avoid the safety hazards brought by the large - amplitude swaying of the trailing cable 11. At the same time, when the cage and the trailing cable 11 descend, the trailing cable 11 can fall into the cable drum.

[0031] In this embodiment, a support pipe 6 is connected to one side of the limiting ring 3, and the support pipe 6 is connected to the pipe body fixed at the construction site through a fastener 7; the pipe body here can be the steel pipe guardrail of the building doorway or window during construction, or the steel pipe of the scaffolding on the outer side of the exterior wall. The fastener 7 uses the commonly used pipe fastener on the construction site, and through the fastener 7, the support pipe 6 can be stably connected to the pipe body at the construction site. The advantages of connecting through the fastener 7 also include: the relative position between the support pipe 6 and the fastener 7 can be adjusted, and thus the distance between the support pipe 6 and the limiting ring 3 from the exterior wall can be changed, so that the distance between the vertical trailing cable 11 and the exterior wall is different; the adjustment needs to ensure that each limiting ring 3 is vertically corresponding.

[0032] Elastic bodies 4 are connected to both sides of the notch of the limiting ring 3, and the ends of the elastic bodies 4 on both sides are in contact with each other. In this embodiment, the positional relationship of the contact between the ends of the elastic bodies 4 on both sides is an up - down relationship; the elastic body 4 is in the shape of a flat rubber plate. The position where the support ring 2 contacts the elastic body 4 is vertically corresponding, and the end of the extension body 1 is vertically corresponding to the inner side of the limiting ring 3.

[0033] In this embodiment, both the upper and lower ends of the support ring 2 are set to be conical. When the extension body 1 ascends with the cage and the trailing cable 11 ascends, the support ring 2 expands the elastic bodies 4 on both sides of the notch of the limiting ring 3 from bottom to top. In this way, the trailing cable 11 passes through the inner side of the limiting ring 3. After the support ring 2 passes, the elastic body 4 resets to close the notch of the limiting ring 3. The elastic body 4 is in the shape of a rubber plate, and the difficulty of its lateral bending is much greater than that of its vertical bending. The swaying of the trailing cable 11 with the wind cannot expand the elastic body 4 to break away from the limiting ring 3. When the extension body 1 descends, the support ring 2 expands the elastic body 4 from top to bottom, which can drive the trailing cable 11 to break away from the limiting ring 3.

[0034] In this embodiment, a U-shaped mounting seat 5 is provided inside the notch of the limit ring 3, and the elastic body 4 is connected to the mounting seat 5 by bolts. One end of the elastic body 4 is located inside the mounting seat 5, and the U-shaped mounting seat 5 can prevent the horizontal deflection of the elastic body 4; the elastic body 4 adopts a bolt connection structure, so that the elastic body 4 can be conveniently replaced when it is damaged.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative efforts, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
