Long-distance optical cable traction device for tunnel engineering

The utility model provides a long-distance optical cable traction device for tunnel engineering. The long-distance optical cable traction device comprises a bottom plate, a rolling shaft structure and a conveying system, the conveying system comprises two conveying belts arranged on the bottom plate, the two conveying belts are arranged in parallel, the two conveying belts can move in the direction perpendicular to the traction direction of the optical cable so as to change the distance between the two conveying belts, and the optical cable is clamped between the two conveying belts for traction; the two rolling shaft structures are close to the two ends of the bottom plate respectively, and the optical cable moves on the rolling shaft structures. The conveying system is located between the two rolling shaft structures. The traction device can be suitable for optical cables of different models, and the optical cables can be effectively protected during long-distance traction. 本实用新型提供一种隧洞工程用长距离光缆牵引装置，包括底板、设置在底
