Abstract
The invention discloses a protective device of an elevating mechanism of a stacker-reclaimer, which aims at overcoming the shortcomings that a bucket wheel of the traditional stacker-reclaimer makes an elevating motion by using only one wire rope, and the sudden fracture of the wire rope can easily cause safety accidents to people or the device, influence the regular production and increase the repair cost. In the invention, the elevating mechanism is provided with two parallel wire ropes, the top of a stand column and a bucket wheel arm support are respectively provided with two parallel sets of pulley blocks corresponding to the wire ropes, wherein the head ends of the wire ropes are respectively fixed on two coaxial rollers of a hoister, the tail ends of the wire ropes are fixed on a hoister platform, and a balancing device which is connected with the tail ends of the two wire ropes is installed on the hoister platform. When one wire rope suddenly fractures, the other wire rope alone can maintain the balance of the bucket wheel arm support, can not cause damage to the stacker-reclaimer or result in personal safety accidents, and can gain time for the replacement of the wire rope, thereby greatly lowering the repair cost, and ensuring the safe and regular production.
Description
Technical field
The invention belongs to protective device, occur the device of accident behind the disconnected rope of specifically a kind of luffing mechanism that prevents stacker-reclaimer.
Background technology
The bucket wheel of stacker-reclaimer is the main working parts of this machine, 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 said luffing mechanism is, an end of steel rope is wrapped on the winch cylinder fixing, and its other end is walked around the assembly pulley on stacker-reclaimer column top and the bucket wheel jib, is fixed on then on the interior winch platform of 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 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 the periodic replacement to steel rope, contingency is still inevitable.How guaranteeing the bucket wheel pitching with the safe operation perfectly safely at work of winch steel rope, is to need at present to solve.
Summary of the invention
Technical matters to be solved by this invention 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 present invention adopts following technical proposals to realize: the luffing mechanism of stacker-reclaimer bucket wheel comprises the winch that is installed on the stacker-reclaimer column inner platform, and is installed in the 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, is fixed on the winch platform in the stacker-reclaimer column, and the assembly pulley on said 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 said winch platform, be equipped with two steel ropes terminally be connected, when wherein steel cable breaks off suddenly, another root steel rope can be supported the balancing device of bucket wheel jib balance separately.
The present invention also has following technical characterictic:
The structure of said balancing device is the equalizing bar two ends with horizontally set, with the end flexible connection of said two steel ropes, erects and is fixed on the bearing on the winch platform, and the intermediate point position of its top and equalizing bar flexibly connects with hinge;
The profile of said 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 connects said on bearing top with hinge;
The following drift angle of said equalizing bar is connected with hinge with bearing top, is on the following drift angle of del, to be installed with flap seat with hinge; 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 said 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 corresponding buffered pad below the equalizing bar two ends on the end face of crashproof seat.
Advantage of the present invention and good effect be, 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 breaks off suddenly, another root steel rope can be supported the balancing device of bucket wheel jib separately, when occurring that wherein steel cable breaks off suddenly; Bucket wheel also has a steel rope of supporting the bucket wheel jib; And can keep original balance, also just can not damage stacker-reclaimer and the personal safety accident occur, also win the time for change steel rope more; Thereby significantly reduced repair cost, guaranteed that the safety of production is normally carried out.
