Description

Technical Field

[0001] This invention relates to the field of aluminum alloy cable tray technology, specifically to an aluminum alloy cable tray. Background Technology

[0002] In the installation of electromechanical facilities in buildings, various cables are often laid. For safety and ease of management, special cable trays are needed for support during the large-scale cable laying process. Using cable trays for centralized laying can make reasonable use of space, provide a support space for the cables, and also provide a protective barrier for the cables. It also facilitates cable maintenance by personnel. Aluminum alloy has low density but high strength, which is close to or exceeds that of high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance, and is widely used in industry.

[0003] Traditional aluminum alloy cable trays mainly consist of the main tray body, cover plate, connecting pressure plate, supports, elbows, tees, reducers, fixing bolts, and grounding accessories. The entire structure is made of stamped aluminum alloy profiles, featuring lightweight, corrosion resistance, and high strength. The tray body stores cables, the cover plate provides dust protection, the supports bear weight and provide overhead fixation, elbows and tees accommodate line turns and branches, and connectors allow for segment splicing. The usage steps are as follows: On-site measurement and layout; installation and fixing of supports; sequential splicing of straight sections of the cable tray; installation of elbows and tees to adapt to the route; laying of strong and weak current cables and orderly arrangement, avoiding cross-extraction; fastening of the cable tray cover plate and tightening of all connecting bolts; installation of grounding accessories and proper bridging grounding; and finally, overall inspection of stability and compliance with line layout requirements.

[0004] When laying electrical wiring in chemical plants, in order to effectively isolate external corrosive media and ensure the long-term safe operation and service life of cables, trough-type cable trays with excellent sealing and protection performance are usually selected. During construction, workers first install the trough-type cable trays in place, and then manually complete the cable threading and laying work inside the cable trays. After the laying is completed, it is also necessary to manually arrange and straighten the scattered cables section by section to avoid the cables crossing and stacking, squeezing and deforming. However, in special working conditions such as salt chemical and seawater chemical industries, the chloride ion content in the air is extremely high, and corrosive media can easily penetrate and erode through the gaps in the cable trays and the outer sheath of the cables, accelerating the aging, cracking, deterioration and pulverization of the sheath, thereby damaging the cable insulation layer and core, and significantly shortening the overall service life of the cables. Summary of the Invention

[0008] Preferably, the guide groove 2 is provided with an arc-shaped groove, and the radius of the arc-shaped groove is equal to the distance between the guide shaft and the shaft body.

[0009] Preferably, two parallel supports are fixedly mounted on another support plate, and a support is rotatably mounted between the two supports. A slider is threadedly connected to the support, and a straightening unit is fixedly mounted on the slider.

The storage container has a feed inlet that communicates with the storage cavity. The support plate with the bracket has a sliding groove. A corrugated pipe is fixedly installed at the bottom end of the conveying pipe and communicates with the storage cavity. The storage container has an adjustment mechanism for controlling the up and down movement of the support plate.

[0011] Preferably, the adjusting mechanism includes a positioning ring fixedly disposed on the side wall of the storage container, a handwheel rotatably disposed on the storage container, the shaft of the handwheel being fixedly connected to the gear, a fixing hole being opened on the positioning ring, and a plurality of fixing holes being evenly arranged among them, a limit rod being slidably disposed on the handwheel, and the limit rod being slidably connected to the fixing hole.

[0012] Preferably, a guide rod is fixedly provided on the bracket, and the guide rod and the reciprocating lead screw are arranged parallel to each other. The slider is slidably connected to the guide rod, and an adjustment mechanism for controlling the rotation of the reciprocating lead screw is also fixedly provided on the bracket.

[0013] Preferably, the clamping surface of the clamping plate is arc-shaped, and the two clamping plates are mirror images of each other, with the conveying plate located in the middle of the two clamping plates.

Multiple evenly arranged clamps are installed at one end of the storage container. After the worker places the cable inside the casing, the internal gears are controlled by rotating a handwheel on the outer wall of the storage container. When rotated counterclockwise, two bearing plates move outward simultaneously, at which point the clamps come into contact with the material at the bottom. Then, a toggle plate controls the storage container to move horizontally along the guide groove inside the casing. During this movement, each clamp can vertically arrange the cables inside the casing, preventing them from crossing or becoming disordered. Furthermore, the storage cavity inside the storage container contains pre-filled powdered epoxy zinc-rich corrosion inhibitor, which slides down the conveyor pipe during the movement of the storage container. Because the conveyor plate... During the adjustment process, the material will come into contact with the surface of the cable. Therefore, when the storage device moves, the conveyor plate will be rotated along with it. The anti-corrosion powder in the conveyor pipe will be collected by the clamping groove. When the clamping groove rotates to the surface of the cable, it will coat the surface of the cable, improving the service life of the cable. When the cable inside the device housing is damaged, the operator moves the storage device to the arc groove. At this time, the guide shaft will drive the storage device to tilt around the shaft. When it reaches the highest point of the arc groove, the operator only needs to gently push the surface of the storage device. At this moment, the storage device will be flipped, with the end with the reciprocating screw facing the side with the cable. The reciprocating screw is rotated by the adjustment mechanism on the bracket, so that the clamping plate reaches the damaged cable. Repeat the previous steps of controlling the movement of the storage device to complete the steps of straightening and applying anti-corrosion agent to the replaced single cable. It is simple and convenient. Attached Figure Description

[0028] Reference Figures 1-8 Multiple parallel connecting columns are fixedly installed on the two support plates 5, and the connecting columns are slidably connected to the storage container 3. The connecting columns on the support plates 5 ensure that the container will not shift its position when it moves up and down.

[0029] Reference Figures 1-3 The outer surface of the outer casing 1 is coated with anti-corrosion vinyl ester paint to ensure that the device has a good service life in special environments.

[0030] The specific solution is as follows: First, workers install the cable tray in place and fix the device on the pre-set brackets. Multiple evenly arranged clamps 62 are installed at one end of the storage container 3. After the workers place the cables inside the outer casing 1, they control the internal gears 34 by rotating the handwheel 33 on the outer wall of the storage container 3. When rotated counterclockwise, the two bearing plates 5 move outwards simultaneously, at which point the clamps 62 come into contact with the material at the bottom. Then, the actuating plate 41 controls the storage container 3 to move horizontally along the guide groove 11 inside the outer casing 1. During this movement, each clamp 62 vertically arranges the cables inside the outer casing 1, preventing them from crossing or becoming disordered. Furthermore, the storage cavity 35 inside the storage container 3 contains pre-filled powdered epoxy zinc-rich corrosion inhibitor, which slides down the conveyor pipe 61 during the movement of the storage container 3. Because the conveyor plate 8 will contact the surface of the cables during adjustment... Because of the contact, the conveyor plate 8 will rotate when the storage device 3 moves, and the anti-corrosion powder in the conveyor pipe 61 will be collected by the clamping groove 81. When the clamping groove 81 rotates to the surface of the cable, it will coat the surface of the cable and improve the service life of the cable. When the cable inside the device housing 1 is damaged, the staff will move the storage device 3 to the arc groove 121. At this time, the guide shaft 44 will drive the storage device 3 to tilt around the shaft 421. When it reaches the highest point of the arc groove 121, the staff only needs to gently push the surface of the storage device 3. At this time, the storage device 3 will be flipped, with the end with the reciprocating screw 53 facing the side with the cable. The reciprocating screw 53 will be rotated by the adjustment mechanism on the bracket 51, so that the clamping plate 62 reaches the damaged cable. Repeat the previous steps of controlling the movement of the storage device 3 to complete the steps of straightening and applying anti-corrosion agent to the replaced single cable. It is simple and convenient.
