The insulated pneumatic telescopic cylinder comprises a piston rod head, a piston rod, a protection ring, a cylinder body and a cylinder tail which are coaxially arranged, the top of the piston rod is bonded with the bottom of the piston rod head, a piston is arranged at the bottom of the piston rod, and the piston is connected with the cylinder body through the protection ring; the cylinder body is bonded with the cylinder tail; the piston rod head is used for being connected with a hot-line work platform, and the cylinder tail is used for being connected with a hot-line work platform base. When compressed gas is injected into the cylinder tail, the piston rod extends out of the cylinder body under the action of air pressure to provide thrust, and when the compressed gas is discharged from the cylinder tail, the piston rod retracts under the action of gravity. The device is used for lifting a hot-line work platform, the cylinder body, the piston and other components are made of insulating materials, and insulation under the voltage of 110 kV can be achieved.
本发明公开一种绝缘气动伸缩缸,包括:同轴设置的活塞杆头、活塞杆、保护环、缸体和缸尾;所述活塞杆的顶部与所述活塞杆头的底部粘接,所述活塞杆的底部设有活塞,通过所述保护环与所述缸体连接;所述缸体与所述缸尾粘接;所述活塞杆头用于与带电作业平台连接,所述缸尾用于与带电作业平台底座连接;所述缸尾注入压缩气体时,所述活塞杆在气压作用下自所述缸体伸出以提供推力,当压缩气体从所述缸尾排出时,所述活塞杆在重力作用下回缩。本发明用于带电作业平台举升,采用绝缘材料制造缸体、活塞等部件,可实现110kV电压下的绝缘。
