In design, just the length computation of hoist rope is completed, at lifting mechanism lower position place travel switch 23, can detect the switch of steel rope at which layer, determine the size of height in the position of which layer by detecting steel rope, when rising while being raised to certain altitude, travel switch 23 is opened, and suspension hook stops upward movement, prevents dangerous the generation.
Limit switch can be adjusted all around, according to different brachiums and different multiplying, is adjusted.
According to an embodiment of the present utility model, when approach switch 22 judgements, when reel 21 ground floor steel ropes only remain three circles, approach switch 22 works, and signal is passed to the power-transfer clutch of indoor design, and power-transfer clutch is closed, and forces reel to be braked at once.
According to an embodiment of the present utility model, jack up unit comprises: the hydraulic efficiency gear of power, sensor and the unloaded Quick-speed braking arrangement of measurement hydraulic efficiency gear pressure are provided for promoting hammer ram.Sensor and unloaded Quick-speed braking arrangement are electrically connected to control setup.
According to an embodiment of the present utility model, when the pressure of control setup judgement hydraulic efficiency gear output reach setting mention the pressure of hammer ram the time, control roll barrel and start to roll up steel rope, promote hammer ram.
When control setup judgement hammer ram arrives specified altitude assignment, control roll barrel and stop rolling up steel rope, record the lifting number of turns of steel rope.
When the hammer ram free fall, when the number of turns of control setup judgement roll barrel rotation adds default threshold value for promoting the number of turns, start unloaded Quick-speed braking arrangement.
According to an embodiment of the present utility model, when adopting single multiplying power to hoist, after ramming for adjacent twice, promote hammer ram, promote the number of turns and be respectively a and b.
During ground floor when steel rope at reel, the diff-H of ramming is that 2 π * (b-a) * (R+r), wherein, R is the reel radius, and r is the steel rope radius.
