Description

Technical Field

[0001] This invention relates to the field of cable-related equipment, specifically a high flame-retardant and anti-interference aviation obstruction light cable. Background Technology

[0002] Cables are common components used in various industries for signal and power transmission. In the aerospace field, cables require superior protective properties.

[0003] Meanwhile, in the production process of this type of cable, because a label needs to be affixed to the outside of the cable's rubber insulation, the required outer sheath cannot be integrally molded and installed. Therefore, the traditional sheath installation mode cannot be applied to the molding and production process of this type of cable. Thus, a new production and assembly mode is needed to meet the requirements of this cable. Summary of the Invention

[0004] In order to meet the above-mentioned dual requirements for cable performance and manufacturing, this invention proposes a special cable for high flame retardancy and anti-interference aviation obstruction lights.

[0005] The technical problem to be solved by this invention is achieved by the following technical solution:

[0006] A high flame-retardant and anti-interference aviation obstruction light cable has a square rubber outer insulation layer. Inside the rubber outer insulation layer are three cable cores, each of which is composed of a copper conductor and a mineral insulation layer wrapped around the copper conductor.

[0007] As a further improvement of the present invention, a filler layer is provided between the rubber outer insulation layer and the three cable cores, and an outer sheath is wrapped around the four corners of the outer side of the rubber outer insulation layer. The filler layer is composed of a large amount of waterproof and fireproof material, providing excellent protection. The outer sheath serves to prevent wear and tear on the corners of the rubber outer insulation layer.

[0008] As another improvement to the present invention, an assembly device for cable forming is proposed, comprising an assembly platform with four-jaw chucks on both sides; a fixing base is installed at the rear of the assembly platform, and a liftable chuck platform is mounted on the fixing base, on which an adhesive application assembly is installed; two loading assemblies are also installed on the assembly platform, each loading assembly being connected to two wrapping racks adapted to the outer sheath. The two four-jaw chucks can be used to fix high flame-retardant and anti-interference aviation obstruction light cables without outer sheaths. The adhesive application assembly is used to apply adhesive to all outer sheaths to facilitate initial bonding to the rubber outer insulation layer. The liftable chuck platform is to prevent interference between the adhesive application assembly and the installation of the outer sheath. The wrapping racks are used to load individual outer sheaths. The loading assemblies are used to connect the outer sheaths to the rubber outer insulation layer of the cable.

[0009] As a further improvement of the present invention, of the two four-jaw chucks, the four-jaw chuck on the left is fixedly mounted on the assembly table, while the four-jaw chuck on the right is slidably mounted on the assembly table. The four-jaw chuck on the right is connected to a type I hydraulic cylinder. That is, the four-jaw chuck on the right can slide. The two four-jaw chucks are used to fix the two ends of the cable respectively. By pulling the type I hydraulic cylinder, the cable can be straightened to facilitate subsequent assembly work.

[0010] As a further improvement of the present invention, the type I hydraulic cylinder is fixedly mounted on an assembly table, which is provided with a groove for sliding the four-jaw chuck on the right side. The above is a conventional design for both the fixed and sliding structures.

[0011] As a further improvement of the present invention, a guide rail and a type II hydraulic cylinder connecting the mounting base are installed on the fixed base, and the mounting base is slidably installed on the guide rail. That is, the mounting base can be raised and lowered by the push and pull of the type II hydraulic cylinder.

[0012] As a further improvement of the present invention, the adhesive application assembly comprises a lead screw, a mounting base connecting the lead screw, four automatic injectors mounted on the mounting base, and a motor and an I-shaped guide rod, all mounted on a mounting plate. The motor is connected to the lead screw, and the mounting base is slidably connected to the I-shaped guide rod. The lead screw is mounted on the mounting plate via bearings. That is, through the drive of the lead screw nut, the four automatic injectors can move horizontally, and during the movement, the four automatic injectors can respectively inject adhesive into the four outer sheaths mounted on the four packaging racks.

[0013] As a further improvement of the present invention, each parcel rack is provided with an L-shaped parcel slot, and each parcel rack is provided with a limiting plate. Specifically, the limiting plate of the upper parcel rack is located on the lower side, and the limiting plate of the lower parcel rack is located on the upper side. That is, the outer sheath can be correspondingly loaded into the parcel slot of the parcel rack. The limiting plate is used to limit the movement of the outer sheath.

[0014] As a further improvement of the present invention, in the two corresponding parcel racks, a cylinder is installed on the upper parcel rack, and a through hole adapted to the shaft of the cylinder is installed on the upper parcel rack. The shaft of the cylinder can extend and retract through the through hole, and press against the outer protective sleeve loaded on the upper side to prevent the outer protective sleeve from falling off before loading.

[0015] As a further improvement of the present invention, each loading assembly consists of a junction seat connecting two package holders, a type III hydraulic cylinder connecting the junction seat, and a type II guide rod for slidingly mounting the junction seat; both the type III hydraulic cylinder and the type II guide rod are fixedly mounted on the assembly table. That is, by pushing the junction seat with the type III hydraulic cylinder, all package holders can be moved toward the location of the rubber outer insulation layer of the cable, thereby achieving docking of the four outer sheaths with the rubber outer insulation layer.

[0016] The beneficial effects of this invention are:

[0017] 1. This invention provides a cable with good insulation, fire resistance, and waterproof performance.

[0018] 2. This invention enables convenient loading of four outer sheaths and automatic glue spraying, making it relatively easy to operate.

[0019] 3. This invention can automatically assemble the four outer sheaths with the outer rubber insulation layer of the cable, thus assisting in the processing and shaping of the cable. Attached Figure Description

[0030] like Figure 1 As shown, a high flame-retardant and anti-interference aviation obstruction light special cable is provided with a square rubber outer insulation layer 1. Inside the rubber outer insulation layer 1, there are 3 cable cores. Each cable core is composed of a copper conductor 5 and a mineral insulation layer 4 wrapped around the copper conductor 5.

[0031] A filler layer 3 is provided between the rubber outer insulation layer 1 and the three cable cores, and an outer sheath 2 is wrapped around the four corners of the outer side of the rubber outer insulation layer 1. The filler layer 3 is composed of a large amount of waterproof and fireproof material, providing excellent protection. The outer sheath 2 prevents wear and tear on the corners of the rubber outer insulation layer 1.

[0032] like Figure 2 As shown, the cable forming assembly equipment includes an assembly platform 6, with four-jaw chucks 7 on both the left and right sides. A mounting base 9 is installed at the rear of the assembly platform 6, and a liftable mounting bracket 10 is mounted on the mounting base 9. An adhesive application assembly is installed on the mounting bracket 10. Two loading assemblies are also installed on the assembly platform 6, each connected to two wrapping racks 22 adapted to the outer sheath 2. The two four-jaw chucks 7 can be used to secure high flame-retardant and anti-interference aviation obstruction light cables without the outer sheath 2 loaded. The adhesive application assembly is used to apply adhesive to all outer sheaths 2 to facilitate initial bonding to the rubber outer insulation layer 1. The liftable mounting bracket 10 prevents interference between the adhesive application assembly and the installation of the outer sheath 2. The wrapping racks 22 are used to load individual outer sheaths 2. The loading assemblies are used to connect the outer sheath 2 to the rubber outer insulation layer 1 of the cable.

[0033] like Figure 1 As shown, of the two four-jaw chucks 7, the left four-jaw chuck 7 is fixedly mounted on the assembly table 6, while the right four-jaw chuck 7 is slidably mounted on the assembly table 6. The right four-jaw chuck 7 is connected to a type I hydraulic cylinder 8. That is, the right four-jaw chuck 7 can slide. The two four-jaw chucks 7 are used to fix the two ends of the cable respectively. By pulling the type I hydraulic cylinder 8, the cable can be straightened to facilitate subsequent assembly work.

[0034] like Figure 1 As shown, the type I hydraulic cylinder 8 is fixedly mounted on the assembly table 6, which has a groove 6a that allows the four-jaw chuck 7 on the right side to slide. The above is a conventional design for both the fixed and sliding structures.

[0035] like Figure 1 As shown, a guide rail 12 and a type II hydraulic cylinder 11 connecting the mounting base 10 are mounted on the fixed base 9. The mounting base 10 is slidably mounted on the guide rail 12. That is, the mounting base 10 can be raised and lowered by the push and pull of the type II hydraulic cylinder 11.

[0036] like Figure 2 , Figure 4 as well as Figure 5 As shown, the adhesive application assembly consists of a lead screw 14, a mounting base 15 connecting the lead screw 14, four automatic injectors 17 mounted on the mounting base 15, and a motor 13 and an I-shaped guide rod 16, all mounted on the mounting base 10. The motor 13 is connected to the lead screw 14, and the mounting base 15 is slidably connected to the I-shaped guide rod 16. The lead screw 14 is mounted on the mounting base 10 via bearings. Through the drive of the lead screw and nut, the four automatic injectors 17 can move horizontally, and during this movement, the four automatic injectors 17 can respectively inject adhesive into the four outer sheaths 2 mounted on the four packaging frames 22.

[0037] like Figure 5 and Figure 6 As shown, each parcel rack 22 has an L-shaped parcel slot 22a and a limiting plate 22b. The limiting plate 22b of the upper parcel rack 22 is located on the lower side, and the limiting plate 22b of the lower parcel rack 22 is located on the upper side. That is, the outer sheath 2 can be loaded into the parcel slot 22a of the parcel rack 22. The limiting plate 22b is used to limit the movement of the outer sheath 2.

[0038] like Figure 5 , Figure 4 as well as Figure 7 As shown, in the two corresponding parcel racks 22, a cylinder 18 is installed on the upper parcel rack 22, and a through hole 22c adapted to the shaft of the cylinder 18 is installed on the upper parcel rack 22. The shaft of the cylinder 18 can extend and retract through the through hole 22c, and press against the outer protective sleeve 2 loaded on the upper side to prevent the outer protective sleeve 2 from falling off before loading.

[0039] like Figure 3 As shown, each loading assembly consists of a junction seat 19 connecting two package holders 22, a type III hydraulic cylinder 20 connecting the junction seat 19, and a type II guide rod 21 that slides the junction seat 19. The type III hydraulic cylinder 20 and the type II guide rod 21 are both fixedly mounted on the assembly table 6. That is, by pushing the junction seat 19 with the type III hydraulic cylinder 20, all package holders 22 can be moved toward the position of the rubber outer insulation layer 1 of the cable, thereby realizing the docking of the four outer sheaths 2 with the rubber outer insulation layer 1.

[0040] Before use, each auto-injector 17 must be filled with glue.

[0041] The specific usage steps are as follows:

[0042] Step 1: Manually place the four outer sheaths 2 into their respective wrapping slots 22a, and press the upper outer sheaths 2 tightly using the cylinder 18.

[0043] Step 2: While the motor 13 drives the lead screw 14 to rotate, causing the four automatic injectors 17 to move horizontally, the four automatic injectors 17 can spray glue onto the four outer sheaths 2 respectively.

[0044] Step 3: After the glue spraying is completed, the Type II hydraulic cylinder 11 pulls up the card holder 10.

[0045] Step 4: Fix the two ends of the high flame-retardant and anti-interference aviation obstruction light special cable without outer sheath 2 using two four-jaw chucks 7, and straighten the cable by pulling it with type I hydraulic cylinder 8.

[0046] Step 5: The type III hydraulic cylinder 20 pushes the confluence seat 19, which causes all the wrapping frames 22 to move toward the location of the rubber outer insulation layer 1 of the cable, thereby connecting the four outer sheaths 2 with the rubber outer insulation layer 1.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
