FIELD: construction. ^ SUBSTANCE: telescopic mechanical support has a stem with an eye (for hinged connection with a lower platform), an outer body with journals for hinged connection on the upper platform. The stem is equipped with slots arranged at the specified distance from each other along the entire length. Slots are arranged along a radius of a rotary shift coupled with the stem and a long key hole. An intermediate body is put coaxially onto the stem. The body is equipped with a rotary shaft, having a slot arranged along a radius of a stem coupled with it at an angle of 90, a finger, a fixator, against which a finger of the rotary shaft rests during its rotation, excluding spontaneous disengagement of a mechanical support against vibration, and also a screw dowel and a support cover. Also on the body there are slots (as on the stem) arranged along the radius of the rotary shaft coupled with it. They are arranged at the specified distance from each other along the entire intermediate body. On the body, in its turn, there is an outer body equipped with a shaft, a finger and a fixator. ^ EFFECT: reduced dimensions of a support, reliable fixation of platforms, perception of loads not only from weight of a platform and process equipment installed on it and from vibration loads. ^ 3 dwg |
