Abstract

The utility model discloses a cantilever bucket-wheel stocker and feeder, which cancels the support post of a cantilever system installed on the rotating part of a slewing gear on the basis of reserving the basic structure of the moving pallet, the gate seat, the slewing gear, the cantilever system, the bucket wheel (the bucket wheel isn't arranged on a simplex stocker), the skip car (a simplex feeder isn't provided with the skip car) of the existing equipment, and a fixed post is arranged at the opposite side of the center of rotation of the cantilever on a gate seat. The upper end of the post is provided with a rotating platform, a cantilever balancing stand and a pulley block which controls the cantilever to move upwards and downwards are arranged on the platform, and the fixed end of the cantilever is hinged to the near center position of the slewing gear on the gate seat. So the improved results omit tens tons of balance weight of the cantilever system arranged on the slewing gear of the existing equipment, thus simplifying the equipment, reducing the power of a driving motor, improving the stability of the equipment and enlarging a cantilever angular, and the utilization rate of the stock yard of the skip car section increases more than twice.

Description

Contilever bucket-wheel stocker and feeder

The invention belongs to bulk material pile, taking equipment field in the operation transportation.

Now, cantilevered bulk material pile, reclaimer still are used in the stock ground widely.The keystone configuration of the stacker-reclaimer of this form has: walking carriage (on rail, moving), and gate seat, swing type mechanism, column, jib system (comprises cantilever shalving, along the sealing-tape machine of cantilever operation, gets the hopper wheel, the cantilever radius-changing mechanism.Cantilever balance weight frame), skip car etc.

It is exactly jib system (jib and be installed in sealing-tape machine bucket wheel on the jib that this kind equipment structurally has an obvious irrational place, radius-changing mechanism, balance weight frame) all be that fixed end by cantilever is installed on the column that is fixed on swing type mechanism one side.This just makes the action of gravity point of jib system away from the center of supporting mechanism (walking carriage), can produce very big moment and also form the trend that complete machine inclines and carries out on swing type mechanism.Therefore have to be installed in the offside of swing type mechanism upper cantilever position, to prevent the shoe that inclines of complete machine with very big counterweight (tens of ton).Owing on equipment, add so many counterweight, must cause corresponding structure to increase, as walking carriage, the motor of revolution and walking.Because being mounted in the column of swing type mechanism upper support jib system, another shortcoming that above-mentioned jib system mounting means brings when revolution, to be subjected to stopping of skip car.In equipment in the past, cantilever can only turn round (is zero line with the track) in positive and negative 115 degree, and this has just caused skip car section stock ground to have greatly and can not utilize.Reduced the degree of utilization in stock ground.

For a long time, those skilled in the art once tried hard to overcome above-mentioned two shortcomings of this kind equipment.But owing to exist the radius of turn that the degree of utilization that improves the stock ground will enlarge column, and reduce the contradiction that counterweight need be dwindled the radius of turn of column, so problem fails to solve even to this day.

The objective of the invention is to design a kind of new cantilever support and mounting means, be used for replacing the structure in the existing equipment, to obtain counterweight that removes rotating part and the double effects that enlarges the cantilever degreeof turn.

Basic structure of the present invention is the walking carriage that keeps existing cantilever type bucket-wheel stacker, reclaimer, gate seat, swing type mechanism, cantilever, bucket wheel, change spoke assembly pulley, cantilever counter-balanced carriage, skip car, different is on the gate seat of cantilever offside, rather than at the rotating part of swing type mechanism a column is installed.Because the relative support of this column (walking carriage) is motionless,, establish a turn table in the column upper end so claim vertical columns here.Luffing mechanism, the cantilever counter-balanced carriage of cantilever all are installed on the turn table of vertical columns upper end.The fixed end of articulating boom on swing type mechanism.Can make the center of the end of cantilever near rotary disk.

Below promptly finishing basic fundamental of the present invention constitutes.

Use good effect of the present invention to be: at first to be to have removed the counterweight of similar weight in jib system (10-40 ton), make swing type mechanism and gate seat and the walking carriage portable and stable that becomes, only for swing type mechanism, its diameter can be dropped to about 4 meters by about 6 meters of original equipment, this has not only saved material, has made things convenient for processing and manufacturing, and makes steering resistance little, the cancellation of adding counterweight has reduced the starting resistance of rotator inertia square, and drive motor power is reduced at double.

In addition, this structure has increased the degreeof turn of cantilever, and cantilever is turned round in ± 150 degree scopes, and stock ground skip car section degree of utilization is doubled.

Simultaneously, because the hinge-point of cantilever is to satisfy the length adjusting mechanism that cantilever is faced upward sealing-tape machine when bowing by moving on to away from center of gyration near center of gyration thereby cancelled in the existing equipment.

The present invention can also be used in the cantilever type bucket-wheel reclaimer of cancellation skip car on heap, the reclaimer basis and the stocker that is used for windrow merely of cancellation bucket wheel, is used to get material merely.

Accompanying drawing 2 is a cantilever bucket-wheel stacker reclaimer constructional drawing involved in the present invention;

Accompanying drawing 3 is a cantilever bucket wheel reclaimer constructional drawing involved in the present invention;

Accompanying drawing 4 is a cantilever stocker constructional drawing involved in the present invention.

Implementation process of the present invention is: based on existing cantilever type bucket-wheel stacker-reclaimer, keep walking carriage 1 wherein, gate seat 2, swing type mechanism 3, cantilever 4, bucket wheel 5, luffing assembly pulley 6, the version of skip car 7 each several parts and mutual syntagmatic.Remove column and counterweight (seeing 11 in the accompanying drawing 1) in the existing installation.On gate seat, one high 700mm is installed with the bearing with cross roller crossed roller bearing, external diameter 4300mm, the turning circle of internal orifice dimension 2800mm forms swing type mechanism.The fixed end of articulating boom on swing type mechanism.Can make the center of the end of cantilever near rotary disk.(welding or bolted) root post 8 is installed on gate seat, and column is arc, and the column height is 10m, and is hunchbacked from center of gyration 6.5m, column upper end and swing type mechanism coaxial line, and the back of a bow is near skip car.The column sectional area is 1.8m * 1.8m.Column can resolve into two, and promptly each one in the both sides of skip car, and can lump together in the upper end.Establish a turn table 9 in the column upper end.Turn table is by an axle that is fixed on post end, and rotates the outer ring by one of bearing installation and constitute cantilever counter-balanced carriage fulcrum is hinged on the turn table, the basic structure of counter-balanced carriage and existing equipment basic identical.The radius-changing mechanism assembly pulley form of cantilever is fixed on assembly pulley one end on the bracing frame of cantilever top, and an end is fixed on the turn table on the column.The mode of operation of cantilever type bucket-wheel stacker-reclaimer of the present invention is: be installed in the swing type mechanism rotation under actuating device (basic identical with the structure on the existing device) promotes on the gate seat when needing the swing of cantilever horizontal direction, the cantilever teeter, by being fixed on the bracing frame 4a on the cantilever, drive the counterweight 10a that tries to stop people from fighting each other and promote the turn table of counter-balanced carriage and rotate, form the rotational that whole jib system constitutes around the swing type mechanism on the gate seat and the rotary table on the column around the column upper end.The rotary angle of cantilever of the present invention is ± 150 degree.When the needs cantilever is faced upward, affect bracing frame on the cantilever directly to form facing upward of cantilever to bow,, affect counter-balanced carriage and cantilever forward to face upward and bow by becoming the spoke assembly pulley simultaneously by the 10a that tries to stop people from fighting each other between bracing frame and the counter-balanced carriage, formation jib system integral body is as one man moved.The present invention can identically use on the cantilever pusher shown in Fig. 3 said cantilever bucket wheel reclaimer and the accompanying drawing 4.Because these two kinds of types are compared with the cantilever type bucket-wheel stacker-reclaimer, except a kind of no skip car, outside a kind of no bucket wheel, other structures can be identical.
