Description

Technical Field

[0001] This invention relates to the field of elevator wiring harness technology, and more specifically, to an anti-interference elevator wiring harness. Background Technology

[0002] Anti-interference elevator wiring harnesses suppress electromagnetic interference through multiple technical means to ensure signal transmission stability. Their core design includes a shielding structure, conductors, and insulation layers. The elevator's traveling cable is an important part of the elevator wiring harness and a key component connecting the car and control cabinet in the elevator system. It is responsible for transmitting power, control signals, and communication data. Its performance directly affects the safety and stability of elevator operation. It provides a stable power supply for elevator motors, lighting, ventilation, air conditioning, and other equipment to ensure normal operation. It supports the elevator control system in real-time monitoring of the operating status and enables communication functions such as emergency calls and video monitoring.

[0003] The shielding structure of the elevator traveling cable adopts a general double or multi-layer shielding layer, such as aluminum foil + tinned copper wire braided shielding layer, with the outer shielding layer grounded, effectively blocking external electromagnetic radiation. Some special models adopt a composite shielding structure to further reduce high-frequency interference. The conductor uses multi-strand finely stranded oxygen-free copper wire to reduce resistance and skin effect, and improve high-frequency signal transmission capability. The insulation layer uses modified flexible PVC or physically foamed material to reduce distributed capacitance and inductance and suppress low-frequency attenuation. In addition, it has tensile and bending resistance design, integrating high-strength galvanized steel wire or aramid yarn as load-bearing elements to adapt to the vertical suspension and frequent bending requirements of elevator traveling cables. The flat structure design facilitates laying in the shaft and reduces space occupation.

[0004] Currently, existing technologies require elevator traveling cables to be suspended vertically within the elevator shaft. One end of the cable is electrically connected to electronic components inside the elevator, while the other end is electrically connected to a control cabinet located above the shaft. This facilitates control of elevator operation and signal transmission. The traveling cable also contains shielding wires for electromagnetic interference suppression. However, the traveling cables used in high-rise elevators are often too long, and the bent and overlapping sections are prone to curling and tangling. During the elevator's ascent and descent, the shielding wires are easily damaged or broken due to repeated bending and pulling, reducing the cable's anti-interference effect and potentially causing elevator malfunctions. Therefore, this technology does not meet current requirements. To address this, we propose an anti-interference elevator wiring harness. Summary of the Invention

[0005] This invention provides an anti-interference elevator wiring harness. This harness can minimize the problem that the shielding wire inside the traveling cable is easily damaged or broken due to continuous bending and pulling during the ascent and descent of the elevator. It ensures the integrity of the shielding wire in the traveling cable as much as possible, improves the anti-interference effect of the traveling cable, and thus reduces elevator malfunctions. It solves the problem mentioned in the background art that the traveling cable in the bent and overlapping part is prone to curling and tangling, causing the shielding wire inside to be bent and pulled and thus easily causing damage, which can easily lead to elevator malfunctions.

[0016] Through the above technical solution, the anti-interference elevator wiring harness provided in this disclosure, when in use: the wire fixing component clamps the end of the traveling cable, reducing the tension on the electrical connection between the end of the traveling cable and the control cabinet, preventing the connection between the traveling cable and the control cabinet from loosening or falling off. The wire fixing component also plays a role in further shielding the electromagnetic interference of the traveling cable. The cable management pulley always supports the bending section of the traveling cable, which can limit the movement path of the traveling cable and prevent the traveling cable from getting tangled or knotted at the bending section. At the same time, the traction rope pulls the sliding frame, traction pulley and cable management pulley through the counterweight, so that the traveling cable does not need to bear the extra weight of the sliding frame, etc., and avoids the traveling cable from breaking due to extra tension, effectively reducing the elevator failure rate.

The terms "first" and "second" are used to distinguish one element from another and do not have sequential or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings denote the same or similar elements, which will not be repeated here.

Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0031] According to some embodiments of this disclosure, an interference-resistant elevator wiring harness is provided, with reference to... Figure 1 — Figure 9 As shown, the anti-interference elevator wiring harness includes a traveling cable 100, a car 110 electrically connected to one end of the traveling cable 100, a counterweight 120 driven by the car 110, and a control cabinet 130 electrically connected to the other end of the traveling cable 100. The traveling cable 100 includes a protective layer 101, a power line 102 wrapped in the protective layer 101, and a shielding wire 103 wrapped in the protective layer 101. The traveling cable 100 also includes a steel wire 104 wrapped in the protective layer 101, a limiting ring 105 fixedly sleeved on the outside of the steel wire 104, a shielding mesh 106 wrapped in the protective layer 101, a video line 107 wrapped in the shielding mesh 106, and a ground wire 108 wrapped in the protective layer 101.

[0032] The protective layer 101 is made of special elastic rubber, which enhances its oil resistance, weather resistance, and UV resistance. The power cords 102 are arranged in four bundles, symmetrically positioned on both sides of the protective layer 101. The shielding wires 103 are arranged in two bundles, symmetrically positioned within the protective layer 101. The steel wires 104 are arranged in two strands, symmetrically positioned within the protective layer 101. The steel wires 104 serve as the tension-bearing elements of the traveling cable 100, providing mechanical support for the suspended traveling cable 100 and bearing its own weight and the tension during operation. This prevents the power cords 102 and shielding wires 103 within the traveling cable 100 from being damaged. The cable 103 and video cable 107 are not subjected to excessive tension and break or are damaged, which helps to extend the service life of the traveling cable 100. The number of limiting rings 105 is set to several, and the several limiting rings 105 are evenly fixed and sleeved on the outside of the steel wire 104. The limiting rings 105 are wrapped and clamped inside the protective layer 101 to prevent the steel wire 104 from sliding relative to the protective layer 101, thereby ensuring the mechanical support of the steel wire 104 for the traveling cable 100. The shielding mesh 106 adopts aluminum foil wrapping or copper wire braiding shielding layer to reduce electromagnetic interference and ensure signal stability. The number of video cable 107 and ground wire 108 is set to one each, and the video cable 107 and ground wire 108 are located in the middle of the protective layer 101.

[0033] An installation plate 131 is installed on the upper side of the elevator shaft, and the installation plate 131 is fixedly connected to the inner wall of the elevator shaft. A first lifting pulley 132 is installed on the upper side of the installation plate 131 and the upper side of the car 110, respectively. A second lifting pulley 133 is installed on the upper side of the installation plate 131 and the upper side of the counterweight 120, respectively. A sling 134 is installed in the elevator shaft, and both ends of the sling 134 are fixedly connected to the installation plate 131. The middle part of the sling 134 passes around the first lifting pulley 132 and the second lifting pulley 133 in sequence. The wheel 133 and the mounting plate 131 are also equipped with a winch (not shown in the figure). The output end of the winch is connected to the first hoisting pulley 132 mounted on the mounting plate 131. Thus, the car 110 is raised and lowered by the cooperation of the winch and the sling 134. This is a technical means well known to those skilled in the art and will not be described in detail here. The car 110 is located in the middle of the elevator shaft, and the counterweight 120 and the traveling cable 100 are located on both sides of the car 110.

[0034] A track 140 is fixedly installed on the inner wall of the elevator shaft. A sliding frame 150 is provided on the side of the track 140 for sliding engagement. A cable management pulley 160 is rotatably installed on the side of the sliding frame 150. The middle part of the traveling cable 100 is sleeved on the side of the cable management pulley 160. A traction rope 170 is provided between the counterweight 120 and the sliding frame 150 for pulling the sliding frame 150. A first guide pulley 171 is fixedly installed on the lower side of the mounting plate 131. The second lead pulley 172 is located above the counterweight 120, and the second lead pulley 172 is located above the sliding frame 150. A traction pulley 173 is rotatably mounted on the outside of the sliding frame 150. One end of the traction rope 170 is fixedly connected to the counterweight 120, and the other end of the traction rope 170 is fixedly connected to the mounting plate 131. The middle part of the traction rope 170 passes through the first lead pulley 171, the second lead pulley 172, and the traction pulley 173 in sequence.

[0035] Both the first guide pulley 171 and the second guide pulley 172 are fixed pulleys, serving to support and guide the traction rope 170. The traction pulley 173 is a movable pulley, serving to save effort and change the pulling distance of the counterweight 120 on the sliding frame 150. Based on the effort-saving characteristic of the movable pulley, when using the traction pulley 173 as a movable pulley to lift the sliding frame 150, the weight of the sliding frame 150 is jointly borne by the two sections of traction rope 170 located on both sides of the traction pulley 173. Therefore, the required pulling force is only half of the weight of the sliding frame 150. Based on the distance relationship characteristic of the movable pulley, although using the movable pulley saves effort, it increases the distance. One end of the traction rope 190, which is fixedly connected to the counterweight 120, is left as a free end, so that the distance the counterweight 120 moves is twice the rising height of the sliding frame 150. This allows the descending counterweight 120 to pull the sliding frame 150 upward by half its height when the car 110 rises, thanks to the traction rope 170. This is a technique well-known to those skilled in the art. When the traveling cable 100 rises with the car 110, the bending section in the middle of the traveling cable 100 rises to half the height of the car 110. The height of the car 110's rise is also consistent with the height of the counterweight 120's descent. This ensures that the sliding frame 150 drives the cable management pulley 160 to rise at the same speed and distance as the bending section of the traveling cable 100, thus ensuring that the cable management pulley 160 is always located at the bending section of the traveling cable 100. This not only restricts the movement and position of the traveling cable 100 but also maintains a sufficiently large bending radius for the bending section of the traveling cable 100.

[0036] The traveling cable 100 is a flat cable. The two sides of the traveling cable 100 with a large spacing are symmetrical arcs, and the two sides of the traveling cable 100 with a small spacing are parallel planes. The protective layer 101 on the side of the traveling cable 100 near the inner wall of the elevator shaft is thicker, making the protective layer 101 on this side more wear-resistant. The protective layer 101 on the side of the traveling cable 100 near the car 110 is thinner, making the protective layer 101 on this side more flexible and bendable. A housing 180 is fixedly installed on the outside of the control cabinet 130. The ends of the traveling cables 100 are commonly inserted into the housing 180 and the side wall of the control cabinet 130, which facilitates the electrical connection between the traveling cable 100 at this end and the electronic components inside the control cabinet 130.

[0037] The housing 180 is provided with a cable-holding assembly 190 for clamping the traveling cable 100. The cable-holding assembly 190 includes a first sliding plate 191 slidably disposed inside the housing 180, a first magnetic core 192 fixedly mounted on the side of the first sliding plate 191, a second sliding plate 193 slidably disposed inside the housing 180, a second magnetic core 194 fixedly mounted on the side of the second sliding plate 193, a fixing ring 195 respectively fixedly mounted on the outside of the first sliding plate 191 and the second sliding plate 193, a fixing rope 196 passing through the fixing ring 195, and a fastening bolt 19 threadedly connected to the side of the housing 180. 7. One end of the fixing rope 196 is fixedly connected to the inner wall of the housing 180, and the other end of the fixing rope 196 is fixedly connected to the fastening bolt 197. The number of first sliding plates 191 is set to two, and the two first sliding plates 191 are respectively located on both sides of the arc surface of the traveling cable 100. The first sliding plates 191 are set to be arc-shaped plates that cooperate with the arc surface of the traveling cable 100. The number of second sliding plates 193 is also set to two, and the two second sliding plates 193 are respectively located on both sides of the parallel surface of the traveling cable 100. The second sliding plates 193 are set to be flat plates that cooperate with the parallel surface of the traveling cable 100.

[0038] Both the first sliding plate 191 and the second sliding plate 193 are made of plastic sheets, and both the first magnetic core 192 and the second magnetic core 194 are made of ferrite magnetic cores that shield the electromagnetic interference of the traveling cable 100. The cable management pulley 160 restricts the position of the bent part of the traveling cable 100 to prevent the bent parts of the traveling cable 100 from getting tangled. The traction rope 170 pulls the sliding frame 150 and the cable management pulley 160 when the counterweight 120 descends, preventing the weight of the sliding frame 150 and the cable management pulley 160 from exerting a downward pulling force on the traveling cable 100, thus preventing damage to the traveling cable 100 and reducing elevator malfunctions.

[0039] Through the above technical solution, the anti-interference elevator wiring harness provided in this disclosure has a thicker protective layer 101 on the side of the traveling cable 100 closest to the inner wall of the elevator shaft when in use. This makes the protective layer 101 on this side more wear-resistant when in contact with the inner wall of the elevator shaft, preventing the protective layer 101 on this side from being severely worn and losing its protective function for the power line 102, shielding line 103 and other wires inside the traveling cable 100. The protective layer 101 on the side of the traveling cable 100 closest to the car 110 is thinner, making the protective layer 101 on this side more flexible and adaptable to the long-term repeated bending requirements of the traveling cable 100. This allows the traveling cable 100 to bend as it moves with the car 110, thus enabling the traveling cable 100 to adapt to different usage scenarios. The video line 107 inside the traveling cable 100 is covered with a shielding mesh 106, which can physically isolate external electromagnetic radiation interference, thereby preventing the traveling cable 100 from being subjected to electromagnetic interference. The car 110 is smoothly raised and lowered by the coordinated use of the first lifting pulley 132, the second lifting pulley 133, and the sling 134. When the car 110 rises, the counterweight 120, descending at the same speed as the car 110, pulls one end of the traction rope 170 downwards. Through the support and guidance of the traction rope 170 via the first guide pulley 171 and the second guide pulley 172, the traction rope 170 drives the traction pulley 173 and the cable-guiding pulley 160 to rise together at half the speed of the car 110's ascent. Simultaneously, the car 110... The 0-drive mechanism moves the end of the traveling cable 100 upward synchronously and at the same speed, causing the bent portion of the traveling cable 100 to rise at half the speed of the car 110. This ensures that the cable management pulley 160 is always located at the bent portion of the traveling cable 100. This not only restricts the movement and position of the traveling cable 100, but also maintains a sufficiently large bending radius at the bent portion of the traveling cable 100. This prevents the bent portions of the traveling cable 100 from getting too close to each other and becoming coiled or tangled, thereby preventing damage to the wires inside the traveling cable 100 and reducing the occurrence of elevator malfunctions. In addition, after the end of the traveling cable 100 near the control cabinet 130 is electrically connected to the control cabinet 130, the fastening bolt 197 is tightened, so that the end of the fixing rope 196 is wrapped around the fastening bolt 197. The tightened fixing rope 196 pulls the first sliding plate 191 and the second sliding plate 193 inward, thereby driving the first magnetic core 192 and the second magnetic core 194 to close inward, wrapping and clamping the outside of the traveling cable 100. This not only clamps and fixes the end of the traveling cable 100 to prevent the connection between the traveling cable 100 and the control cabinet 130 from loosening or detaching, but also forms a complete shielding magnetic ring on the outside of the traveling cable 100 through the closing cooperation of the first sliding plate 191, the first magnetic core 192, the second sliding plate 193 and the second magnetic core 194, further reducing the electromagnetic interference of the traveling cable 100. In summary, the cable fixing assembly 190 clamps the end of the traveling cable 100, reducing the tension at the electrical connection between the end of the traveling cable 100 and the control cabinet 130, preventing the connection between the traveling cable 100 and the control cabinet 130 from loosening or falling off. The cable fixing assembly 190 also further shields the traveling cable 100 from electromagnetic interference. The cable management pulley 160 always supports the bending section of the traveling cable 100, limiting the movement path of the traveling cable 100 and preventing tangling and knotting at the bending section. At the same time, the traction rope 170 pulls the sliding frame 150, traction pulley 173, and cable management pulley 160 through the counterweight 120, eliminating the need for the traveling cable 100 to bear the additional weight of the sliding frame 150, etc., and preventing the traveling cable 100 from breaking due to additional tension, effectively reducing the elevator failure rate.
