本发明公开了一种牵引机构,其包括气缸、运动活塞、绳索、固定支座和平衡气腔。所述气缸经由固定支座与所述平衡气腔连通,与所述运动活塞相连的所述绳索穿过所述固定支座并穿过所述平衡气腔被引出,封堵所述平衡气腔的两端壁与绳索为间隙配合,所述固定支座开设有进气主管路,用于为运动活塞的运动提供驱动气,所述平衡气腔上连接有气源管路,在试验时始终被提供补偿气,以使得所述平衡气腔内的压力始终稍大于所述固定支座中的压力,所述运动活塞在驱动气的作用下带动绳索在气缸内作高速运动。本发明结构简单,易于检修和维护,并解决了绳索穿孔的动态密封问题。

    The invention discloses a traction mechanism. The traction mechanism comprises an air cylinder, a moving piston, a rope, a fixing support and a balance air cavity. The air cylinder communicates with the balance air cavity through the fixing support. The rope connected with the moving piston penetrates through the fixing support and the balance air cavity and then is led out. The two end walls sealing the balance air cavity are in clearance fit with the rope. The fixing support is provided with an air inlet main pipeline used for providing driving air for movement of the moving piston. The balance air cavity is connected with an air source pipeline which is provided with compensation air all the time during testing so that the pressure inside the balance air cavity can be a little larger than the pressure in the fixing support all the time, and the moving piston drives the rope to move at a high speed in the air cylinder under the driving of the driving air. The traction mechanism is simple in structure, and easy to overhaul and maintain, and the dynamic sealing of rope perforating is achieved.
