DEVICE FOR SUSPENSION AND MASS CONTROL OF HOIST WORKING PLATFORM |
摘要 |
FIELD: transportation. ^ SUBSTANCE: device contains force-sensing element installed on hoist boom head with possibility of plane-parallel movement. This element is connected with working platform base via power transmitting units provided with strain gage transducers. Force-sensing element of hoist boom head and working platform base are interconnected by means of two parallel and mutually spaced force-transmitting units made in the form of force-measuring sensors of magnetic-loop type with edge attachment to force-sensing element of hoist and working platform base by means of threaded fasteners. Each of the mentioned force-measuring sensors of magnetic-loop type comprises two parallel force-sensing beams positioned one above the other and symmetrically spaced relative to longitudinal sensor axis each one of which is made in the form of bolster with rectangular cross-section and has its own measuring section where in side walls of force-measuring beam counter-directed blind holes are made separated by thin vertical force-measuring divider on which its own strain gage transducer is fixed; and two vertical elements interconnecting end parts of force-sensing beams with creation of force-measuring frame in which elements the receivers for the mentioned threaded fasteners are made. ^ EFFECT: device reliability enhancement and reduction of labor consumption during device mounting on hoist. ^ 7 cl, 7 dwg |
