Description
Technical field
The present invention relates to a kind of material grabbing device of hoisting crane, be specifically related to a kind of gas suction grappling bucket.
Background technology
At present, grab crane is mainly used for the loading and unloading of bulk goods material in the big harbour of domestic each, and grab bucket is a kind of load-engaging device of cranage bulk cargo, and its structure mainly comprises steel rope, pulley, entablatrance, cross sill, strut and jaw.Because common grab bucket structure design is unreasonable, therefore when grasping the less powder material of particle with grab bucket, open in the process of discharging, often produce bigger dust in grab bucket, be unfavorable for the healthy of field man, surrounding environment is also caused certain pollution.
Summary of the invention
Technical matters to be solved by this invention is: a kind of gas suction grappling bucket is provided, and it can realize dustless equalization in discharge process.
The technical scheme that the present invention solves its technical matters employing is: comprise the grab bucket main body, and the dust eliminating equipment that is connected with the grab bucket main body, they constitute gas suction grappling bucket.
The present invention compared with prior art, its advantage mainly is: owing to adopted later-model structure, therefore in discharge process, can open the electrical motor that is installed in the grab bucket entablatrance by remote controller, sponge the dust of kicking up around the grab bucket by aspirate tube, thereby realized dustlessization of grab bucket in discharge process, can improve the environment of work-site like this, avoid the pollution that causes to surrounding environment, help the healthy of field man simultaneously.

The specific embodiment
The present invention is a kind of grab bucket that is used to load and unload the bulk goods material, and its structure is: comprise the grab bucket main body, and the dust eliminating equipment that is connected with the grab bucket main body, they constitute gas suction grappling bucket.
The invention will be further described below in conjunction with example and Fig. 1 to Fig. 3.
Gas suction grappling bucket provided by the invention, the same prior art of structure of its grab bucket main body mainly comprises entablatrance 3, strut 4, cross sill 6, pulley 7, journal stirrup 8, jaw 9, hinge 10, steel rope 11.
Gas suction grappling bucket provided by the invention, its dust eliminating equipment are remote operated dust eliminating equipment.This dust eliminating equipment mainly is made up of bellows 2, control box 13, storage battery 14, and they are installed on the entablatrance 3.The bottom of bellows 2 is connected with aspirate tube 5, and the lower end of this aspirate tube is stretched in the cross sill 6 and captive joint with it.Consider that air suctiton ventilator 15 needs electricity consumption, control box 13 receives also electricity consumption of remote signal, so storage battery 14 the two poles of the earth are introduced into control box, control air suctiton ventilator 15 after the output again, therefore: control box 13 input ends link to each other by lead 12 with storage battery 14, and control box 13 mouths link to each other with the air suctiton ventilator 15 that is arranged in bellows 2 by lead 12.
Described aspirate tube 5 can be made by aluminum alloy, and exit skirt 17 is made in its lower end, helps sucking wider dust like this.
Described bellows 2, its inner chamber are filtered net 16 and are divided into upper and lower two-layerly, and air suctiton ventilator 15 is installed on the upper strata, and lower floor holds the cavity that sucks dust.The outside of bellows 2 is provided with air outlet 1.Air suctiton ventilator 15 can pass through bonding way or other connection mode, is installed in the loam cake central authorities of bellows 2.The arbor of air suctiton ventilator 15 links to each other with flabellum 18.When air suctiton ventilator 15 runnings, can make air flow supreme layer from the lower floor of bellows 2, discharge from air outlet 1 then.Air suctiton ventilator 15 is powered by storage battery 14, and by shaking the running and the speed governing of this air suctiton ventilator of control realization.
Above-mentioned bellows 2 have two, so that strengthen the dust effect that absorbs.Two bellows can be made cylindrical or other shape by aluminum alloy, and they are welded on the two ends of entablatrance 3 respectively.
Above-mentioned filtering net 16, available intensive metal gauze are made into circular or other shape big with bellows 2 internal diameters etc., guarantee that metal has only less space on the net, for example adopt 200～400 orders.This filtering net and the welding of bellows 2 inwalls.
Described entablatrance 3 is welded with one and can holds control box 13 and storage battery 14 metal cabinets on it, they are between two bellows 2.
Gas suction grappling bucket provided by the invention, its concrete working process is as follows:
When steel rope 11 drove pulley 7 rotations, jaw 9 was opened, the beginning discharging; If produce bigger dust, send signal by driver in the operator's compartment by remote controller, the device and the control circuit of received signal arranged in the control box 13, thereby start air suctiton ventilator 15, and can control the operating speed of air suctiton ventilator 15 according to the signal that receives.
The dust that produces during discharging enters in the aspirate tube through exit skirt 17 under the air-flow effect that aspirate tube 5 produces, and enters bellows 2 then, and dust impassabitity filtering net 16 is blocked in the lower floor of bellows 2, and air sees through filtering net 16 by air outlet 1 discharge.After dust has been absorbed around the grab bucket, close air suctiton ventilator 15 by remote controller; Air suctiton ventilator 15 stops operating, aspirate tube 5 no longer produces inspiratory airflow, if this moment, bellows 2 lower floors stored more dust, this dust is because under the influence of self gravitation and the vibration of generation when grab crane moves, finally can fall into aspirate tube automatically, discharge from bellows 2 then.
Gas suction grappling bucket provided by the invention can use under existing technical conditions.
