Step 202, according to formula Ht=Hz-Hs-Lk, it is adjusted the height of set 3；
Selected adjusting sleeve 3 is sleeved on measuring rod 2 by step 203, and measuring rod 2 is stretched out to the top of adjusting sleeve 3
It is screwed into the threaded hole of crossbeam 1-1, until the lower surface of crossbeam 1-1 and the upper surface of the adjusting sleeve 3 are in close contact；
Step 3: the measurement of guide slip shoe abrasion loss:
Step 301, during coalcutter is along fully-mechanized mining working back production, judge that bowing for coalcutter adopts whether angle is greater than
10 °, when coalcutter bow adopt angle no more than 10 ° when, execute step 302；Otherwise, step 303 is executed；
Step 302, when coalcutter bow adopt angle no more than 10 ° when, only to the upper guide surface 4- of the guide slip shoe 4
2 abrasion loss measures, specific as follows:
Step 3021, the top surface that bottom plate 1-2 is mounted on to pin row 6, and measuring rod 2 is inserted into measured hole 7, described in record
Initial scale L1 of the top surface of measured hole 7 on the second graduated scale 2-3；Wherein, the center line of the measuring rod 2 and measurement
The center line in hole 7 is overlapped；
Step 3022 is adopted in exploitation process of the angle no more than 10 ° in bowing for coalcutter, records the top of the measured hole 7
Face change on the second graduated scale 2-3 after scale L ' 1；
Step 3023, according to formula Hmds=| L ' 1-L1 |, obtain the abrasion of the upper guide surface 4-2 of the guide slip shoe 4
Measure Hmds；
Step 303, when coalcutter bow adopt angle greater than 10 ° when, only to the lower guide surface 4-3 of the guide slip shoe 4
Abrasion loss measure, it is specific as follows:
Step 3031, the top surface that bottom plate 1-2 is mounted on to pin row 6, and measuring rod 2 is inserted into measured hole 7, described in record
Initial scale L2 of the top surface of measured hole 7 on the first graduated scale 2-2；Wherein, the center line of the measuring rod 2 and measurement
The center line in hole 7 is overlapped；
Step 3032 is adopted in exploitation process of the angle greater than 10 ° in bowing for coalcutter, reads the top surface of the measured hole 7
Scale L ' 2 after changing on the first graduated scale 2-2；
Step 3033, according to formula Hmz=| L ' 2-L2 |, obtain total abrasion loss H of the guide slip shoe 4 and pin row 6mz；
Step 3034 is leaned against in pin row 6 with the U-shaped frame body card, obtains the actual height H ' of pin row 6x, and according to formula
Hmx=Hx-H′x, obtain the abrasion loss H of pin row 6mx；Wherein, HxIndicate the initial calibrated altitude of pin row 6；
