Abstract

The invention relates to an inflatable seal cable laying drawing head made of aluminum alloy, belonging to the field of cable application. The inflatable seal cable laying drawing head comprises a cable conductor, an inflatable anti-bending drawing head, a conductor press-connecting pipe, a cable metal sheath, a tail-end inflatable sealing cap, an inflatable nozzle and a barometer; the cable conductor is inserted into and press-connected with the conductor press-connecting pipe so that the cable conductor is compacted; the conductor press-connecting pipe is fixed on the inflatable anti-bending drawing head; one end of the cable metal sheath is fixedly welded with the inflatable anti-bending drawing head, and the other end of the cable metal sheath is fixedly welded with the tail-end inflatable sealing cap; the inflatable nozzle is arranged on the tail-end inflatable sealing cap; and the barometer is arranged on the inflatable nozzle. The invention can effectively improve the drawn bearing tension in the cable laying process and simultaneously has reasonable structure and design, convenient machining and installation, no harm to the human body, large bearing tension, high sealing and waterproof effects, low cost and convenient field construction monitoring.

Description

technical field [0001] The invention relates to an aluminum alloy inflatable sealed cable laying traction head, which belongs to the field of cable application. Background technique [0002] Now the cable installation and laying process needs to pass through long-distance pipes or ditches, which requires a traction force. If this force is directly applied to the cable, it will cause irreversible damage to the cable insulation. Therefore, it is necessary to equip the cable with a traction head. The pulling head must bear a considerable pulling force; at the same time, in order to ensure the internal sealing, waterproof and moisture-proof of the cable, the pulling head must also have a sealing effect, and it is necessary for customers to monitor the air pressure during cable laying. In the prior art, the traditional pulling head used in the cable installation and laying process is either not strong enough to withstand the pulling force, or the sealing and waterproof effect is ...
