Embodiment Construction
[0013] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0014] Such as figure 1 with figure 2 As shown, the telescopic arm of the step suspension plate is composed of the wedge angle connection seat 4 fastened on the ring beam 7, the single ear support 2 fastened on the wedge angle connection seat 4, the pin shaft 3, and the hydraulic cylinder 1. Assemblies, the sliding wedge assembly that slide wedge block 6, guide groove 5 constitute, and the counterrotating assembly that double ear sliding sleeve 10, counterrotating screw mandrel 12, positioning screw mandrel 11 etc. constitute three components. Wherein, the inclined plane angle of the single-ear support 2 installed on the wedge-angle connecting seat 4 is equal to the inclined angle of the sliding wedge 6, and the inclined angle of the sliding wedge 6 is generally 13-20 degrees, according to the friction coefficient of the friction panel and the well wall ...
