What is directly penetrated stretches into caging bolt hole, and is fastened by stop nut, the free end of caging bolt is located at the downside of main beam
Between the upper side wall of wall and crosshead sheave crossbeam.When car overload, the elastic force of spring deficiency, under the lower wall of main beam can continue
Drop, in order to avoid causing spring breaking down to the excess compression of spring, this programme is designed with caging bolt, caging bolt upper end from
By holding between main beam and crosshead sheave crossbeam, too low main beam lower wall can encounter the free end of caging bolt, obtain
Caging bolt it is spacing, avoid further declining.
Preferably, lateral Displacement plate is fixed with the lower wall of main beam or the upper side wall of crosshead sheave crossbeam, lateral limit
Position plate is located between the lower wall of main beam and the upper side wall of crosshead sheave crossbeam, and bearing of trend is longitudinal direction, highly no more than spacing
Length of the bolt between the lower wall of main beam and the upper side wall of crosshead sheave crossbeam.Lateral Displacement plate is set close to caging bolt
Put, bearing of trend is also above-below direction, when caging bolt stress distorts, can be prevented by the spacing of lateral Displacement plate
Distortion further development.It so can significantly eliminate the destruction when car is overweight to spacing protecting mechanism.
Preferably, lateral Displacement plate towards caging bolt free end side covered with yielding rubber.Yielding rubber makes
Caging bolt will not produce new vibrations when touching lateral Displacement plate.
In summary, the beneficial effects of the utility model are：With advantage simple in construction, also with multiple protection machines
Structure, it can play a protective role during to overweight overload.
