Difference between cable tray and line slot

電纜橋架是支架.托臂和裝置附件組成的，建筑物內橋架可以獨立架設，也可以附設在各種建(構)筑物和管廊支架上，應表現結構簡略，造型漂亮.裝備靈敏和修理便利，悉數零件均需進行鍍鋅處理，裝置在建筑物外露天的橋架。那今日就來說一下電纜橋架設備軋輥的運用特點吧。

Cable bridge frame is composed of brackets, brackets and accessories. The bridge frame in the building can be erected independently or attached to various buildings and pipeline Gallery brackets. It should be simple in structure and beautiful in shape. The equipment is sensitive and convenient to repair. All parts need galvanizing treatment. It is installed on the bridge frame outside the building in the open air. Now let's talk about the characteristics of the roller of the cable tray equipment.

1.軌跡圓弧部位是滑軌中心部位,前幾道壓成型后的圓弧位,在后道次軋折立邊時,應對已成型的圓弧,經過上下軋輥或橫輪,進行有用管制維護。

1. The trajectory arc is the center part of the sliding track, and the arc position after the first several passes of pressing should be controlled and maintained by upper and lower rollers or crosswheels when the vertical edge is folded in the back passes.

2.電纜橋架設備資料在拉伸過程中圓弧位一定會改變,R變小成為三角形,鋼珠不究竟,兩點觸摸發生噪音音,R變大時,合作軌發生晃動,滑軌運用時軌跡含糊,受力不均,滑軌變形,縮短壽數。

2. The arc position of cable bridge equipment data will change in the process of stretching, R will become triangle, steel beads will not be exactly, noise will occur when two touches occur, and when R becomes larger, the cooperative rail will sway, the track is ambiguous when the sliding rail is used, the force is uneven, the sliding rail will deform and the life will be shortened.

3.各道次均勻受力準則,全線滾輪均勻受力,磨損均衡,延伸軋輥運用壽數。

3. uniform force criterion for all passes, uniform force and wear balance for all rollers, extending roll life.

4.滾輪加工準確度是要害,為此,專門制造專用工具在投影設備下,擴大20倍進行檢測。

4. Accuracy of roller processing is the key. For this reason, special tools are specially manufactured under projection equipment, which is expanded by 20 times for testing.

5.壁厚程度不同；金屬線槽的壁厚一般比電纜橋架小，所以線槽一般不作為接地線PE運用的，但小尺度線槽.橋架的壁厚差不多，電纜橋架的強度.承載才能要比線槽好得多。

5. The thickness of the wall is different; the thickness of the metal groove is generally smaller than that of the cable bridge, so the groove is generally not used as the grounding line PE, but the small-scale groove. The wall thickness of the bridge is similar, and the strength and bearing capacity of the cable bridge are much better than that of the cable groove.

6.型式不同；電纜橋架的型式也比線槽多，線槽往往是帶蓋板的。

6. type is different; the type of cable tray is also more than that of wire slot, and the line slot is often covered with cover.

7.防腐措施不同；電纜橋架往往是鍍鋅的居多，線槽往往是涂漆.噴塑。

7. anticorrosive measures are different; the cable tray is often the most zinc plating, and the groove is often painted.

8.防腐目標不同；電纜橋架用玻璃鋼橋架時防嚴重腐蝕，線槽則用塑料線槽應對嚴重腐蝕。

8. Anti-corrosion objectives are different. Fiberglass reinforced plastics (FRP) bridges are used to prevent serious corrosion, while plastic grooves are used to cope with serious corrosion.
