QG—1020吊管机在未改之前,车高5.7米,宽3.18米,改装后车高2.25米,宽3.5米。改装结构(见下图),从扒杆铰链连接销中心处往上2.5米截开,附加上滑轮架组。车型左边的滑轮支架组上的中间滑轮由旋转180°改为旋转270°。这样截开的扒杆放平过来之后,中间滑轮就可自行转到下面,使扒杆摆放平稳可靠。扒杆放平和竖起,由操纵起落扒扦的卷扬机和起落吊勾的卷扬机来完成。扒杆竖起之后,拧紧截开处的螺丝,然后由弹簧套组顶开扒杆,即可进行吊装工作。
Before unmodified, the QG-1020 pipelayer has a height of 5.7 meters and a width of 3.18 meters. The modified car has a height of 2.25 meters and a width of 3.5 meters. Modified structure (see below), from the grill lever hinge pin center 2.5 m up cut, add pulley block group. The middle pulley on the pulley block on the left side of the vehicle model was changed from 180 ° rotation to 270 ° rotation. This cut-off par put flat over, the middle of the pulley can be transferred to the following, so that the pole placed smooth and reliable. Stripping pole put flat and erected, by manipulating the razor gear rappelling and landing hoist hanging hook to complete. After the bar is erected, tighten the screws at the cut-off place, and then open the bar by the spring set to carry out the lifting work.
