液压钻车,在其凿岩过程中,为了防止由工作面上岩石给它的反作用力而后退,都设有稳车装置。通常的方法是用油缸支撑起车体,使车轮离开轨面(地面),依靠本身重量稳车。然而,不同的钻车上,稳车装置的结构形式并不完全一样。 CGJ2Y钻车的稳车装置设有四个支腿,前两个支腿的结构形式如图1所示。这种装置的主要特点是: 1.与每个支腿一个油缸相比,减少了一 Hydraulic drilling rig, in its rock drilling process, in order to prevent the rock from the face of the reaction to force it to retreat, are equipped with a steady vehicle. The usual method is to use the cylinder support from the body, leaving the wheel track (ground), relying on its own weight steady vehicle. However, different rigs, the steady car device structure is not exactly the same form. CGJ2Y rig steady vehicle has four legs, the structure of the first two legs as shown in Figure 1. The main features of this device are: 1. Reduced by one compared to one cylinder per leg
