The utility model entire work process was divided into for five steps, and advancing to the right with hoisting crane is example:
The first step, during the crane travel mechanism motion, real-time wind speed and wheel speed are monitored in the work of the utility model monitoring assembly; Under the hoisting crane normal operation, retainer spring 7 upwards lifts connecting rod 8, and caging bolt 6 stops connecting rod 8 to be carried on excessive simultaneously, makes connecting rod 8 and touch pole 1 form certain angle, thereby the distance of control power transmission assembly and wheel makes triggering controlled in time;
In second step, in the hoisting crane operational process, when meeting sudden fitful wind, monitoring assembly monitors that wind speed surpasses certain grade and the hoisting crane wheel speed reaches certain numerical value, triggers assembly and triggers braking;
The 3rd step; Thrust shaft 4 promotes touch pole 1 left in the triggering assembly, touch pole 1 drivening rod 8 and holder 10 are to left movement, holder 10 stretches to the hoisting crane bogie wheels with long steel disc 11, termination rubber 12 on the long steel disc 11 contacts with bogie wheels, when termination rubber 12 with after bogie wheels contacts, be subjected to the promotion of triggering component on the one hand, rotated by bogie wheels presses down, long steel disc 11 is pushed down rapidly by the hoisting crane bogie wheels, and at this moment, the retainer spring 7 of triggering component is elongated slightly;
In the 4th step, long steel disc 11 is pushed down by the hoisting crane bogie wheels, and bogie wheels is pressed on the long steel disc 11 and moves ahead; Long steel disc 11 is relative with ground static; The touch pole 1 that triggers assembly moves ahead with hoisting crane, driving holder 10 moves right, and long steel disc 11 is pushed down, the long relatively steel disc 11 of holder 10 slides, when moving to adding of long steel disc 11, holder 10 holds disengaging section 15, be subjected to long steel disc 11 width reduce separate with long steel disc 11 under the answer tension with retainer spring 7; Simultaneously, shock absorber also moves with hoisting crane, because long steel disc 11 is pushed down, the following steel rope 20 that links to each other with long steel disc 11 length that is stretched, make S. A. 19 rotate, S. A. 19 moves into steel rope 18, and extension spring 17 is drop-down the stretching of downward pulling force of the advance drive and the last steel rope 18 of hoisting crane cross sill;
The 5th step, the a plurality of bogie wheels of hoisting crane are pressed on the long steel disc 11, the braking force that long steel disc 11 can provide also increases gradually, the pulling force that is subjected to of extension spring 17 increases gradually simultaneously, when extension spring 17 is stretched to a certain degree, its spring force reaches the maximum force of sliding friction that wheel load produces, last steel rope 18 no longer moves into S. A. 19, following steel rope 20 no longer lays out, long steel disc 11 produces the maximum cliding friction dynamic braking of performance of sliding with ground, static until hoisting crane, S. A. 19 is fixing under the effect of click structure, prevents S. A. 19 counter-rotatings.
Principle of work of the present utility model is exactly that the hoisting crane chassis is when advancing, wheel is pushed down long steel disc, the relative ground of long steel disc is left standstill, hoisting crane moves round about relatively, cross sill and cart anchoring device drive Buffer Unit and move, this duration steel disc and hoisting crane cross sill produce pulling force to the extension spring two ends respectively, when the elastic force of extension spring self equates with the pulling force that is subjected to, no longer stretch, distance and position between long steel disc and cross sill are fixed, and this moment is under the compression weight of hoisting crane chassis self, long steel disc can not move, then the cross sill of hoisting crane can not move, and also is that hoisting crane can not continue to advance again, realizes the static of hoisting crane.
