弹簧补偿装置

Spring Tensioning Device 弹簧补偿装置

1. Application 用途

Tensioning Device is to be used in platform, tunnel and other special position, it includes accessories up to the insulator (excluded), and the fixing to the wall in the tunnel or to the mast in the open route, and it should include the rope, bracket and the connecting parts.

站内站台区范围内、隧道内特殊部分接触悬挂下锚，采用弹簧补偿装置，包括绝缘子（除外）以及与锚臂或支柱的附件。

2. Layout plans for Spring Tensioning Device 弹簧补偿装置配置方案

Basically, there are 2 series of Spring tensionning device, TR450 and TR750,length expansion of TR450 is 450mm and compensation tensile is

6-22.5KN;length expansion of TR750 is 750mm and compensation tensile is 5-22.5KN; for higher tensile, 2 Spring tensionning device shall be used in parallel.

总的来说，棘轮产品一共两个系列：TR450 和TR750, TR450 的张紧调节量为450mm，补偿张力为6-22.5KN ;TR750 的张紧调节量为750mm，补偿张力为5-22.5KN. 如果需要更高的拉力，可以并排使用两个弹簧补偿装置。

a. When cable tensile is 15KN,a set of TR750/1500 CAT.790/197 shall be adopted, the length expansion is 750mm;

线张力为 15KN，弹簧补偿装置选用TR750/1500 CAT.790/197 一套，张紧调节量750mm;

b. When cable tensile is 25KN, 2 sets of TR750/1275 shall be adopted, thelength expansion is 750mm.

2线张力为25KN，弹簧补偿装置选用TR750/1275 两套，张紧调节量750mm。

c. When cable tensile is 8.5KN, a sets of TR750/850 shall be adopted, thelength expansion is 750mm.

线张力为8.5KN，弹簧补偿装置选用TR750/850 一套，张紧调节量750mm

d. The detailed configuration solution and the type of the product will be defined during the Design Liaison Meeting.

e. The technical information including the detailed material of the component shall be provided during the Design Liaison Meeting.
