With the frictional force of guide rail, roller mount limits movement of the pushing-pulling-rack in guide rail left and right directions.
Further, at the position on the pushing-pulling-rack above and below the side far from the roller mount and the corresponding guide rail side
It is rotatable to be equipped with upper roller and bottom roller.
Advantageous effect using above-mentioned further scheme is：Mounted in pairs above and below top sheave, lower sheave, for limiting push-and-pull
The movement of frame upper and lower directions, top sheave, downslide wheel construction are identical, easily produce in batches, save processing cost.
Further, the centre position on the drill boom is equipped with rack seat, and the rack is fixed on described by installation bolt
On rack seat.
Further, the idler wheel can be rolled by roller shaft at the corresponding position of the pushing-pulling-rack, and two
The roller shaft is connected by limiting the snap-gauge of its rotation, and the snap-gauge is fixed on the pushing-pulling-rack pair by fixing bolt
At the position answered.
Advantageous effect using above-mentioned further scheme is：Roller shaft is fixed to realize the rotation of idler wheel.
