Background technology
The main working parts of stacker-reclaimer is a bucket wheel, and bucket wheel needs luffing at work, and the luffing mechanism of stacker-reclaimer is for the luffing in the bucket wheel work is provided with.The structure of described luffing mechanism is, an end of steel rope is wrapped on the winch cylinder fixing, and its other end is walked around the column top of stacker-reclaimer and the assembly pulley on the bucket wheel jib, is fixed on then on the winch platform in the stacker-reclaimer column.The positive and negative rotation of the cylinder of winch can make bucket wheel face upward the landing campaign of bowing.
In the goods yard, the busy handling labor of stacker-reclaimer makes bucket wheel do frequent luffing, thereby has accelerated the tired and wearing and tearing of winch steel rope.Existing bucket wheel luffing mechanism, the steel rope on its winch cylinder is single.In case fracture suddenly takes place in steel rope, will make bucket wheel lose bearing capacity and fall, and then stacker-reclaimer be caused badly damaged, what influence was produced normally carries out, and has also increased repair cost, even the personal safety accident can occur.
At present, the safe operation of winch steel rope guarantees by periodic replacement and daily attention.But although can accomplish daily attention and periodic replacement to steel rope, contingency is still inevitable.How to guarantee that the bucket wheel pitching with the safe operation perfectly safely at work of winch steel rope, is to need at present to solve.
The utility model content
Technical problem to be solved in the utility model is, it is single that the bucket wheel that overcomes existing stacker-reclaimer is made the used steel rope of luffing, in case fracture suddenly takes place, cause people, machine safety misadventure easily, influence ordinary production, increased the shortcoming of repair cost, a kind of protective device of stacker-reclaimer luffing mechanism is provided.
In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: the luffing mechanism of stacker-reclaimer bucket wheel, comprise the winch that is installed on the stacker-reclaimer column inner platform, and be installed in assembly pulley on column top and the bucket wheel jib, the head end of steel rope is fixed on the cylinder of winch, its end is walked around the assembly pulley on column top and the bucket wheel jib, be fixed on the winch platform in the stacker-reclaimer column, assembly pulley on described column top and the bucket wheel jib is arranged side by side two groups, simultaneously steel rope is with assembly pulley cooresponding two arranged side by side, on described winch platform, be equipped with two steel ropes are terminal and be connected, when wherein steel cable disconnected suddenly, another root steel rope can be supported the balancing device of bucket wheel jib balance separately.
The utility model also has following technical characterictic:
The structure of described balancing device is the equalizing bar two ends with horizontally set, with the end flexible connection of described two steel ropes, erects the bearing that is fixed on the winch platform, and the intermediate point position of its top and equalizing bar flexibly connects with hinge;
The profile of described equalizing bar is an equilateral triangle, and its installation site is the downward handstand shape of drift angle, and leg-of-mutton drift angle down is connected described bearing top with hinge;
The following drift angle of described equalizing bar is connected with hinge with bearing top, is to be installed with flap seat with hinge on the following drift angle of del; The left and right sides of flap seat vertically is symmetrically fixed with two boatswain chairs perpendicular to flap seat below the inboard of bearing is positioned at hinge, and two boatswain chairs pass with transverse axis, its two ends be fixed on bearing about on the two inboard facades;
On described stacker-reclaimer winch platform, be positioned at the both sides of equalizing bar lower seat, respectively corresponding equalizing bar two ends below, erect and be fixed with crashproof seat, be separately installed with cooresponding cushion rubber below the equalizing bar two ends on the end face of crashproof seat.
Advantage of the present utility model and good effect are, because the steel rope of winch is arranged side by side two, two steel ropes are in the fixed point of stacker-reclaimer frame, be equipped with when wherein steel cable disconnects suddenly, another root steel rope can be supported the balancing device of bucket wheel jib separately, when occurring that wherein steel cable disconnects suddenly, bucket wheel also has a steel rope of supporting the bucket wheel jib, and can keep original balance, just can not damage stacker-reclaimer yet and the personal safety accident occur, also won the time, thereby significantly reduced repair cost, guaranteed that the safety of producing normally carries out for change steel rope more.
