Description

Technical Field

[0001] The utility model belongs to the technical field of cables, in particular to a cable for elevators. Background Art

[0002] Elevator cable is a traveling cable installed in the elevator shaft. One end of the cable is connected to the top of the shaft and the other end is connected to the car. It can provide overall electrical control under long suspension conditions while bearing mechanical stress.

[0003] Elevator cables are generally flat in design, consisting of a lined-up inner cable core and a protective sheath on the outside. However, signal transmission interruptions often occur during elevator operation. This is because there are many angle steels on the elevator shaft wall, and the cable, under the influence of its own gravity, will stick to the shaft wall. As a result, the angle steels will scratch the protective sheath during movement, exposing the cable core. Utility Model Content

[0004] The utility model aims to solve the problems of the prior art and provides an elevator cable. The specific technical solution is as follows:

[0005] The elevator cable comprises a body, wherein a plurality of supporting fins are equidistantly arranged outside the body along its laying direction. The supporting fins are arranged around the body to form a radial extension of the body, forcing a gap between the body and the hoistway wall.

[0006] As a further technical solution of the present invention, the supporting fins are integrally formed with the body, and the supporting fins are made of the same material as the outer layer of the body.

[0007] As a further technical solution of the present invention, the support fins are detachably connected to the body, and the support fins can be slidably arranged outside the body. The body has radially extending ridges, and the ridges are equidistantly provided with notches corresponding to the support fins.

[0008] In the installed state, the supporting fin is snapped into the notch.

[0009] As a further technical solution of the present invention, the supporting fins are deformable and recoverable after deformation.

[0010] As a further technical solution of the present invention, the main body includes, from the inside to the outside, a cable core assembly and a protective sleeve covering the cable core assembly. The protective sleeve has an interlayer therein, and the interlayer is woven from metal wires.

[0011] As a further technical solution of the present invention, the cable core assembly includes reinforcing ribs and plum blossom wire cores that are arranged in a line and alternately.

[0012] The beneficial effects of the utility model are as follows:

[0013] In this application, by arranging support fins on the outside of the cable to form a radial extension, a gap can be forced between the cable and the shaft wall, so that the cable and the shaft wall form indirect contact through the support fins, thereby preventing the cable from being scratched by the angle steel, thereby protecting the cable.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] The present application provides a solution based on the prior art that there is a risk of the cable being cut by angle steel due to the close distance between the cable and the shaft. Support fins are equidistantly arranged on the outside of the cable along the laying direction of the cable, so that there is a gap between the cable and the shaft wall, forcing the cable to form indirect contact with the shaft wall through the support fins, thereby protecting the cable.

[0020] Figure 1 It shows a schematic structural diagram of the main body 100 in a working state; Figure 2 shows a schematic cross-sectional structural diagram of the body 100; Figure 1 and Figure 2In the figure, a plurality of supporting fins 200 are equidistantly arranged outside the body 100 along its laying direction. The supporting fins 200 are arranged around the outside of the body 100 to form a radial extension of the body 100, forcing a gap between the body 100 and the well wall. Since the support fin 200 forms an extension end of the main body 100 in the radial direction, one end of the support fin 200 contacts the wellbore wall, which can push the main body 100 open and force the main body 100 away from the wellbore wall, thereby preventing the angle steel from scratching the main body 100, thereby protecting the main body 100; and since the support fin 200 will interfere with the angle steel instead of the main body 100; the support fin 200 has deformability and recoverability after deformation. When it interferes with the angle steel, the support fin 200 can deform in time to pass over the angle steel, and can reset in time after passing over the angle steel to maintain support for the main body 100. For example, the material of the support fin 200 is the same as the outer layer material of the main body 100, both are PVC material, or the support fin 200 is an elastic copper sheet, which is a steel copper material plated with tin or silver.

[0021] The supporting fins 200 are integrally formed with the body 100 ; since the body 100 and the supporting fins 200 are integrally formed, the supporting fins 200 are formed at the same time as they are extruded, which makes the forming simple and the laying convenient.

[0022] The support fin 200 is detachably connected to the body 100. The support fin 200 can be slidably arranged outside the body 100. The body 100 has a radially extending ridge 130, and the ridge 130 has equidistant notches 131 corresponding to the support fin 200. The support fin 200 is sleeved on the outside of the body 100 and can slide along the outside of the body 100. The setting of the ridge 130 can guide and limit the support fin 200 to prevent the support fin 200 from winding around the body 100. During relative rotation, the notch 131 can serve as a place to accommodate the supporting fin 200, and the supporting fin 200 can be stuck in the notch 131 to ensure the stability of the supporting fin 200. It should be noted that the internal formation of the supporting fin 200 matches the notch 131, and the supporting fin 200 will squeeze the ridge 130 and force it to deform during the sliding process on the surface of the main body 100. Moreover, since the ridge 130 is made of PVC material, it will not prevent the supporting fin 200 from sliding.

[0023] See Figure 2The main body 100 includes, from the inside to the outside, a cable core assembly 110 and a protective cover 120 wrapped around the cable core assembly 110. The cable core assembly 110 includes reinforcing ribs 111 and plum blossom wire cores 112 that are arranged in a row and alternately. The reinforcing ribs 111 and the plum blossom wire cores 112 are arranged alternately, and there is a reinforcing rib 111 between each of the two adjacent groups of plum blossom wire cores 112. The reinforcing ribs 111 can avoid interference between the two adjacent groups of plum blossom wire cores 112, and the arrangement of multiple groups of reinforcing ribs 111 can ensure the overall strength of the main body 100; there is an interlayer 121 in the protective cover 120, and the interlayer 121 is woven from metal wires; the woven protective cover 120 not only ensures the bending effect of the main body 100, but also can protect the cable core assembly 110 when the angle steel scratches the main body 100, thereby preventing the plum blossom wire core 112 from being exposed.

[0024] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
