It is interior.
Preferably, through hole 51 is the waist hole with certain length, and vertically, waist hole allows to arrange the length direction of waist hole
Baffle 5 moves up and down along its length direction, and during locomotive driving, wheel machine to caused by abrasion inevitably occurs
The phenomenon of car height to the top of rail reduction, or the height of pilot is required, it now need to only loosen the spiral shell of installation troubleshooting plate 5
Bolt, troubleshooting plate is moved up, then the bolt of fixed troubleshooting plate 5 is tightened.Further, can be by central row
The waist hole that opens up is horizontally disposed on barrier part 3, i.e., perpendicular with the waist hole that is opened up on troubleshooting plate 5, due to center troubleshooting part 3
With the first troubleshooting part 1, center troubleshooting part 3 and the second troubleshooting part 4 when mounted, there can be certain deviation on horizontal direction, should
Horizontal deviation can have an impact to the installation of troubleshooting plate 5, and the waist hole that this is laterally set can eliminate these deviations.
When needing to install pilot provided by the present invention, can follow the steps below：
First troubleshooting part 1 and the second troubleshooting part 4 are respectively fixedly connected with locomotive underframe by supporting plate 6；First troubleshooting
The space of installation center troubleshooting part 3 is reserved between the troubleshooting part 4 of part 1 and second, for placing center troubleshooting part 3；
Center troubleshooting part 3 is positioned between the first troubleshooting part 1 and the second troubleshooting part 4, passes through the first connecting plate 8 and second
The bolt hole set on connecting plate 9 makes the first troubleshooting part 1 and center troubleshooting part 3, the second troubleshooting part 4 and center troubleshooting part 3 respectively
It is connected, but does not fasten；
According to the size in the gap between the first connecting plate 8 and the second connecting plate 9, by one or more of suitable thickness
The gap that adjustment backing plate 2 is filled between the first connecting plate 8 and the second connecting plate 9, is then fastened；
Troubleshooting plate 5 is passed through into the company of fixation of through hole 51 that is opened up on the first troubleshooting part 1, the second troubleshooting part 4, center troubleshooting part 3
It is connected to the first troubleshooting part 1, the second troubleshooting part 4, the front portion of center troubleshooting part 3.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or using the present invention.
A variety of modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle, it can realize in other embodiments without departing from the spirit or scope of the present invention.Therefore, this hair
It is bright to be not intended to be limited to the embodiments shown herein, and be to fit to and principles disclosed herein and features of novelty phase
