Abstract
Description
Technical Field
[0001] This invention relates to the field of cable technology, specifically a flat elevator monitoring cable. Background Technology
[0002] In the existing technology, elevator monitoring cables are used to monitor the situation inside the elevator and can be divided into video cables, audio cables and alarm cables. On the one hand, the monitoring cables need to move up and down with the elevator and have good toughness; on the other hand, the monitoring cables generate a lot of heat because they work 24 hours a day, and if a lot of heat accumulates inside the cable, it will affect the working performance of the cable.
[0003] For example, the patent document with publication number CN 102915810 A discloses "a special cable for elevator monitoring"; the technical solution includes an insulated conductor, a shielding layer and an outer sheath layer arranged sequentially outside the insulated conductor, two strands of spun yarn symmetrically arranged between the shielding layer and the outer sheath layer, and two power lines symmetrically arranged between each strand of spun yarn and the outer sheath layer; each power line is wrapped with an insulating layer; the insulated conductor is arranged between the two symmetrical strands of spun yarn, and the insulated conductor includes a copper wire conductor, with an insulating layer wrapped around the copper wire conductor.
[0004] The cables in this technical solution have excellent stability, anti-interference, tensile strength, and flexibility. They are not easily damaged during use, which improves the service life of the cables. They are mainly suitable for video transmission and signal control in elevator monitoring systems.
[0005] However, the above technical solutions cannot effectively reduce the heat generated inside the monitoring cable during operation. The heat will accumulate inside the cable and cannot be effectively dissipated, resulting in reduced performance.
[0006] Therefore, in order to solve the above problems, it is necessary to develop a flat elevator monitoring cable that can reduce the internal heat of the cable. Summary of the Invention
[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a flat elevator monitoring cable; the technical solution is as follows:
[0008] A flat elevator monitoring cable includes a cable core and two sets of corresponding semi-circular frames; each set of semi-circular frames has several units, and the two ends of the semi-circular frames in the same set are connected and installed as a whole by connecting plates. The two sets of corresponding semi-circular frames can be spliced together to form an integral frame. The space inside the two corresponding semi-circular frames is set as a placement space, and the cable core is placed in the placement space.
[0009] Each set of semi-circular frames is also connected to and installed with a sealing plate at the rear end. The sealing plate is tangent to the rear end of the semi-circular frame. The area between the sealing plate and the semi-circular frame is set as a water storage chamber, which stores cold water. After the cable core is installed in the placement space, the two sets of semi-circular frames are installed together. The two sets of semi-circular frames are also provided with a wrapping layer to wrap the overall structure into a flat structure. The wrapping layer is also provided with an outer sheath.
[0010] Furthermore, each group has three semicircular frames, forming three placement spaces, and the cable cores are correspondingly arranged in three placement spaces.
[0011] Furthermore, the cable core includes an innermost conductor, an insulation layer outside the conductor, a shielding layer outside the insulation layer, an armor layer outside the shielding layer, and an inner sheath outside the armor layer.
[0012] Furthermore, the interior of the semi-circular skeleton is also provided with annular pads, and the annular pads between the corresponding semi-circular skeletons form an overall circular pad structure.
[0013] Furthermore, corresponding positions of the connecting plates at both ends of the semi-circular frame are provided with locking blocks and slots. When the semi-circular frames are installed together, the locking blocks are locked into the slots accordingly.
[0014] Furthermore, the shielding layer is configured as a steel wire braided layer, the armor layer is configured as a steel wire strip armor layer, and both the inner and outer sheaths are configured as flame-retardant ring protective sleeves.
[0015] Furthermore, the semi-circular frame is configured as an aluminum frame or a plastic frame structure.
[0016] Beneficial effects: The present invention has the following beneficial effects:
[0017] (1) The cable of the present invention is first set with two sets of semi-circular skeletons. Each set of semi-circular skeletons is connected by a connecting plate and its length can be extended. After the two sets of semi-circular skeletons are aligned, the cable core can be placed in the placement space accordingly. The outer layer is wrapped and an outer sheath is installed. The whole structure forms a flat cable structure, which has very good toughness when moving up and down with the elevator. The internal cable core is also well protected.
[0018] (2) In this invention, the rear end face of each set of semi-circular skeletons is also connected and installed by a sealing plate. The sealing plate can seal the rear area of the semi-circular skeleton into a water storage cavity. Cold water can be stored in the water storage cavity. In this way, when the cable works for a long time, the heat generated inside can be absorbed by the water, thereby reducing the temperature of the internal cable. The heat will gradually dissipate from the outside, which can ensure the working performance of the cable.
[0019] (3) The connecting plate of the present invention is provided with a card block and a card slot, which can facilitate the installation of the semi-circular skeleton during docking. The cable core is also provided with an armor layer to increase toughness. In addition, the semi-circular skeleton can be made of aluminum skeleton or plastic skeleton to increase bending ability.

[0020] Figure 1 This is a structural diagram of the present invention. Detailed Implementation
[0021] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented based on the technical solutions of the present invention, and it should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0022] like Figure 1 As shown, a flat elevator monitoring cable includes a cable core 1 and two sets of corresponding semi-circular frames 2; each set of semi-circular frames 2 is provided with several, and the two ends of the semi-circular frames 2 in the same set are connected and installed as a whole by connecting plates 3, and the two sets of corresponding semi-circular frames 2 can be spliced into an overall frame. The space inside the two corresponding semi-circular frames 2 is set as a placement space 6, and the cable core 1 is placed in the placement space 6.
[0023] Each set of semicircular frames 2 is also connected to and installed with a sealing plate 4 at the rear end. The sealing plate 4 is tangent to the rear end of the semicircular frame 2. The area between the sealing plate 4 and the semicircular frame 2 is set as a water storage chamber 5, which stores cold water. After the cable core 1 is installed in the placement space 6, the two sets of semicircular frames 2 are installed together. The two sets of semicircular frames 2 are also provided with a wrapping layer 7 to wrap the overall structure into a flat structure. The wrapping layer 7 is also provided with an outer sheath 8.
[0024] The cable of this invention firstly sets two sets of semi-circular skeletons. Each set of semi-circular skeletons is connected by a connecting plate and its length can be extended. After the two sets of semi-circular skeletons are aligned, the cable core can be placed in the corresponding placement space. The outside is wrapped with a wrapping layer and an outer sheath is installed, thus forming a flat cable structure. It has very good toughness when moving up and down with the elevator, and the internal cable core is also well protected.
[0025] Each set of semicircular frames 2 has three, forming three placement spaces 6. Correspondingly, three cable cores 1 are set up and placed in the three placement spaces 6.
[0026] The cable core 1 includes an innermost conductor 101, an insulation layer 102 outside the conductor 101, a shielding layer 103 outside the insulation layer 102, an armor layer 104 outside the shielding layer 103, and an inner sheath 105 outside the armor layer 104.
[0027] In this invention, the rear end face of each set of semi-circular skeletons is also connected and installed by a sealing plate. The sealing plate can enclose the rear area of the semi-circular skeleton into a water storage cavity, in which cold water can be stored. In this way, when the cable works for a long time, the heat generated inside can be absorbed by the water, thereby reducing the temperature of the internal cable. The heat will then gradually dissipate from the outside, ensuring the working performance of the cable.
[0028] The interior of the semi-circular frame 2 is also provided with annular pads 9, and the annular pads 9 between the corresponding semi-circular frames 2 form an overall circular pad structure.
[0029] The connecting plates 3 at both ends of the semi-circular frame 2 are also provided with corresponding positions of locking blocks 10 and slots 11. When the semi-circular frame 2 is installed, the locking blocks 10 are locked into the slots 11.
[0030] The shielding layer 103 is a steel wire braided layer, the armor layer 104 is a steel wire armor layer 104, the inner sheath 105 and the outer sheath 8 are both flame-retardant ring protective sleeves; the semi-circular frame 2 is an aluminum frame or plastic frame structure.
[0031] In this invention, the connecting plate is provided with a locking block and a locking slot, which facilitates the installation of the semi-circular frame during docking. In addition, the cable core is also provided with an armor layer to increase toughness. Furthermore, setting the semi-circular frame as an aluminum frame or a plastic frame can increase bending capacity.
[0032] The above-described specific embodiments are merely preferred embodiments of the present invention and are not intended to limit the implementation of the present invention or the scope of the claims. All equivalent changes and modifications made in accordance with the scope of patent protection of the present invention should be included within the scope of the present invention patent application.
