Description

Technical Field

[0001] This invention belongs to the field of elevator technology, specifically relating to a windproof protective cover for elevator traveling cables. Background Technology

[0002] The traveling cable runs with the elevator car at one end, while the other end is fixed in the hoistway or machine room. In enclosed hoistways, it is affected by airflow within the hoistway; in open hoistways, it is also affected by external airflow. Chinese Patent Document 1 (CN117142280A) provides protection for the traveling cable by limiting its perimeter. However, because the traveling cable is a flat cable and experiences deflection stress during both stationary and dynamic elevator movements, it will inevitably deflect. Forcibly limiting its perimeter would cause the cable to be under torsional stress for extended periods, reducing its lifespan. Chinese Patent Document 2 (CN104261224A) reduces the stress on the cable and increases its lifespan by using dual motors and figure-eight clamps to secure the wire rope and cable. However, this method cannot prevent the traveling cable from colliding with other objects in the hoistway. In open hoistways, this solution does not provide wind protection. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a windproof protective cover for elevator traveling cables. The cover body is integrally formed by a first side baffle, a top plate, a second side baffle, and a back plate through a continuous bending process. The cover body extends longitudinally, and its length covers the entire operating range of the traveling cable.

[0004] Preferably, the connection between the first side panel and the top panel, the connection between the top panel and the second side panel, and the connection between the top panel and the back panel all adopt a rounded bend design.

[0005] Preferably, the back panel is bent to both sides to cover the gap between the back panel and the first side panel and the second side panel.

[0006] Preferably, strip-shaped sound-absorbing cotton, a first small sound-absorbing cotton, and a second small sound-absorbing cotton are provided in the gap between the top plate and the back plate, the first side baffle, and the second side baffle. The thickness of the strip-shaped sound-absorbing cotton, the first small sound-absorbing cotton, and the second small sound-absorbing cotton is slightly greater than the gap width.

[0007] Preferably, the top plate has a cable hole at its center, one end of the traveling cable passes through the cable hole, and the other end passes through the middle of the first side baffle and the second side baffle and is installed in the car.

[0008] Preferably, both the first side panel and the second side panel have protective edges installed on the side edges facing the accompanying cable. Attached Figure Description

[0009] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Figure 1 This is a frontal view of the windproof protective cover of Embodiment 1; Figure 2 This is a side-rear view of the windproof protective cover of Embodiment 2. Detailed Implementation

[0010] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can fully understand other advantages and technical effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through different specific embodiments, and the details in this specification can also be applied based on different viewpoints, with various modifications or changes made without departing from the overall design concept of the invention. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other. The following exemplary embodiments of the present invention can be implemented in many different forms and should not be construed as being limited to the specific embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the technical solutions of these exemplary embodiments to those skilled in the art. Example 1

[0011] like Figure 1 and Figure 2As shown, the windproof protective cover for the elevator traveling cable provided in this embodiment is integrally formed by a first side baffle 3, a top plate 1, a second side baffle 2, and a back plate 6 through a continuous bending process. The cover extends longitudinally, its length covering the entire operating range of the traveling cable. The connections between the first side baffle 3 and the top plate 1, the top plate 1 and the second side baffle 2, and the top plate 1 and the back plate 6 all employ a large-radius arc bending design. This not only avoids stress concentration at sharp corners and improves structural strength, but more importantly, effectively prevents the protective cover from attracting and interfering with magnetic components such as reed switches and sensors on the counterweight, ensuring the normal operation of the elevator. Since it is a continuously bent sheet metal part, gaps exist between the sheet metal parts. The back plate 6 is bent to both sides to cover the gaps between the back plate 6 and the first side baffle 3 and the second side baffle 2. The gaps between the top plate 1 and the back plate 6, the first side baffle 3, and the second side baffle 2 are covered by strip-shaped sound-absorbing cotton 5, a first small sound-absorbing cotton 7, and a second small sound-absorbing cotton 8. The strip-shaped sound-absorbing cotton 5, the first small sound-absorbing cotton 7, and the second small sound-absorbing cotton 8 are made of high-temperature resistant, flame-retardant, and non-aging materials. Their thickness is slightly larger than the gap width to ensure that they can fully absorb the airflow sound waves passing through the gap, significantly reducing the operating noise in the hoistway. One end of the traveling cable passes through the cable hole in the center of the top plate 1, and the other end passes through the middle of the first side baffle 3 and the second side baffle 2 and is installed to the corresponding position in the car. Protective edges 4 are installed on the edges of the first side baffle 3 and the second side baffle 2 facing the traveling cable to protect the cable.

[0012] The windproof protective cover for the elevator traveling cable in this embodiment has the following technical advantages: 1. One-piece molded structure for higher strength It adopts a continuous bending and one-piece molding process, which has good overall rigidity, no weak points at the joints, and is not easy to deform after long-term use, and is easier to install.

[0013] 2. The rounded bend design eliminates safety hazards. A large-radius circular arc transition avoids stress concentration at sharp corners and improves structural strength; at the same time, it prevents the protective cover from being attracted and interfering with the magnetic components of the counterweight, ensuring stable elevator operation.

[0014] 3. Enclosed and windproof to resist the influence of airflow. The backplate is bent and the gaps are sealed with sound-absorbing cotton to form a complete protective space, which effectively blocks the airflow in the open / closed shaft and prevents the cable from swinging or colliding.

[0015] 4. Sound absorption and noise reduction, improving the operating environment. High-temperature resistant, flame-retardant, and non-aging sound-absorbing cotton fills the gaps, absorbs airflow sound waves, and significantly reduces operating noise in the well.

[0016] 5. Flexible protection extends cable life. The cable is not forcibly restricted to avoid torsional stress; the edge protection protects the cable, reducing wear and scratches and significantly extending the service life of the accompanying cable.

[0017] 6. Adaptable to continuous operation, providing comprehensive protection. The cover longitudinally covers the entire operating range of the cable, providing full protection against wind, impact, and scratches, and offering reliable protection both when stationary and in motion.

[0018] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the invention, and these should also be considered within the scope of protection of the present invention.
