Replacement of insulator for live working: metal lifting tool

 

 

 

將導線提升或收緊的工具有導線鉤和各種卡具。這些卡具的主要材料是選用超硬鋁LC4。它的特點是比強率高、重量輕、良好的工藝性。導線鉤的頂端與絕緣拉桿（板）連成整體。為了防止損傷導線，接觸導線的四只鉤子均加工有圓滑過渡弧?？ň哂虚]式卡具、耐張端頭卡具、直線卡具、大刀卡具和通用卡具。

 

The tools for lifting or tightening wires are wire hooks and various clamps. The main material of these fixtures is super hard aluminum LC4. It is characterized by high specific strength, light weight and good processability. The top end of the wire hook is connected with the insulating pull rod (plate) as a whole. In order to prevent damage to the conductor, the four hooks contacting the conductor are all processed with smooth transition arc. The card has closed clamp, tension end clamp, linear clamp, big knife clamp and general clamp.

 

 

 

閉式卡具與雙行程的普通絲桿或省力絲桿配套，可更換耐張或直線絕緣子串間的單片絕緣子。其前后卡具分別與耐張端頭卡具的后、前卡配套，則可更換耐張或直線絕緣子串兩端的絕緣子。

 

The closed clamp is matched with the double stroke ordinary screw rod or labor-saving screw rod, and can replace the single insulator between the tension or linear insulator strings. The front and rear clamps are matched with the back and front clamps of the tension end clamps respectively, so the insulators at both ends of the tension or linear insulator string can be replaced.

 

耐張端頭卡具。前、后卡具與絕緣承力拉桿（板)、絲桿串連后，將其分別組裝在與絕緣子串兩端連接的金具上，來更換耐張整串絕緣子。

 

Tension end clamp. After the front and rear clamps are connected in series with insulated bearing rod (plate) and screw rod, they are respectively assembled on the hardware connected with both ends of insulator string to replace the whole strain insulator string.

 

直線卡具?？ㄔ谥本€聯板上，兩側用絕緣承力拉桿（板）和單行程絲桿，來更換直線整串絕緣子。

 

Straight line fixture. It is clamped on the straight-line joint plate, and the insulated bearing pull rod (plate) and one-way screw rod are used on b
