Abstract

The utility model relates to an abrator for a steel form, which solves the problems that the existing abrators have, such as manpower adoption which is of high labor intensity, poor quality and low efficiency. The utility model comprises an impeller head, an impeller head device, a conveyer device of the abrator, a shot blasting bucket, a spiral conveyer, a bucket elevator, a separating device for abrasive grit and a storage container for the abrasive grit, which are all connected together. The utility model has the advantages that except manual loading and unloading the abrasive grit, the steel form can realize full automatic production from transportation, shot blasting, abrasive grit circulation and separate reuse to dust removal by ventilation; the replacement of manual cleaning by the automatic shot blasting enables the accumulated dust and the rust on the surfaces of the steel form to be cleaned thoroughly and enables the natural color of the steel form to be exposed and restored as a new one.

Description

The steel form shot-blast cleaning machine

The utility model is a kind of steel form shot-blast cleaning machine.

Along with the develop rapidly of world architecture industry, to build, the quality requirement of structures is also more and more higher, thereby the steel form loose tool is just had a higher standard and combination size.Use the practice of steel form loose tool to learn for many years by countries in the world: in application in practice, not only require the flatness of combination loose tool to standardize, and the also necessary very cleaning in its surface, the cement of removing the contamination of construction rear surface accumulates thing, or even iron rust.Like this, could improve construction quality and prolong service life of steel form.

Steel form after the use needs correction and the repair welding except being out of shape and damaging, its superficial dust and corrosion are all quite serious, need thoroughly cleaning, the present cleaning of China all is artificial, its labour intensity is big, and of poor quality and the low of productivity ratio all is conspicuous, especially large-scale template lease station, the template that pile up like a mountain, the cleaning problem is particularly outstanding.

The purpose of this utility model is to solve above-mentioned existing problem, and a kind of raising cleaning quality and efficient are provided, and prolongs the template steel form shot-blast cleaning machine in service life.

The utility model is achieved in that

Four ramming heads are installed on the throwing case that liner is housed by the ramming head device, template is by on the roller-way that manually places it in shot-blasting machine conveying device right side, right-to-left by the roller-way holder and carry out prune job by throwing case: throw the abrasive mixture that falls after beating and collect and be transitted to the bucket elevator that is installed on the throwing case rear wall by the conveying worm of throwing the case bottom, bucket elevator rises to a high position with abrasive material and is separated by the abrasive material separator that is installed on the bucket elevator front face; The abrasive material tank is installed in the end opening of abrasive material separator, and it is multiplexing for ramming head that separated abrasive material falls to entering the abrasive material tank.

Advantage of the present utility model is, except that artificial loading and unloading, template is from carrying impeller blasting, abrasive material circulation, the full-automation production of separation multiplexing and dust removal by ventilation, with mechanization, the impeller blasting of automation replaces manual cleanup, the dust stratification and the corrosion of thoroughly removing template surface, make template surface expose true qualities, restore as new.Application of the present utility model not only promotes the raising of construction quality, but also alleviates the labour intensity of cleaning widely, improves cleaning quality and efficient significantly, also can prolong the service life of template, has bigger economic benefit and social benefit.

In addition, the utility model also can be used for reinforcing bar (as screw-thread steel), the cleaning rust cleaning of steel pipe (as scaffold) outer surface.

This machine structure is superior, compactness.

The drawing explanation:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a left hand view of the present utility model;

Fig. 3 is a ramming head part-structure schematic diagram of the present utility model;

Fig. 4, Fig. 5 are driving, tensioning, the tuningout structural representation gone up of the present utility model;

Describe in detail below in conjunction with accompanying drawing:

As shown in the figure, four ramming heads 1 are installed in by ramming head device 2 on the throwing case 3 that liner is housed, and on the roller-way of template by the right side that manually places it in shot-blasting machine conveying device 4, right-to-left by the roller-way holder and carry out prune job by throwing case 3; Throw the abrasive mixture of whereabouts after beating and collect and be transitted to the bucket elevator 6 that is installed on the throwing case rear wall by the conveying worm 5 of throwing the case bottom, bucket elevator 6 rises to a high position with abrasive material and is separated by abrasive material separation 7 devices that are installed on the bucket elevator front face; Abrasive material tank 8 is installed in the end opening of abrasive material separator 7; It is multiplexing for ramming head that separated abrasive material falls to entering abrasive material tank 8;

Said ramming head mainly comprises by the ramming head dish 11 that 8 blades 10 are installed, and is bearing in the throwing wheel shaft 14 and the ramming head casing 9 that is lined with the wear-resistant white cast iron liner of ramming head bearing block 13, throws on the wheel shaft 14 straight shape blade or arc shaped blade can be installed, and has interchangeability; Throw wheel shaft 14 and adopt 1: 12 cone to add the structure that flat key connects, be sleeved on together, realize dividing ball centering with the centering face of centering ring 17 with driving-disc 18 and shot wheel 16 with the hub 12 of dumping; Control cover 15 is housed between shot wheel and blade, and control cover 15 can rotate in 360 ° of scopes, thereby it is adjustable in 360 ° of scopes to realize that ramming head goes out the ball angle.

Said conveying worm, mainly comprise the helical axis of forming by left and right spiral plate and middle impeller, the one end is by the taper roll bearing of a pair of back of the body dress, the other end is being thrown the case bottom by containing by sleeve supporting, collects abrasive material that falls after throwing is beaten and the Lower Hold that is sent to bucket elevator by impeller with it.

Driving on it, tensioning, tuningout structure are that motor 23 passes through V belt, the gear reduction unit 19 that is sleeved on the upper belt-wheel axle head drives upper belt pulley 22 and rotates, and the upper belt pulley axle is lifted on bucket type together with gear reduction unit 19 by a pair of adjustment bolt 21 of a pair of self-aligning ball bearing 20 usefulness and carries on the box body 25; Be fixed on the position of the adjuster 24 adjustment decelerators 19 on bucket elevator casing 25 outer walls.Thereby adjust the elasticity of helical feed screening machine chain, adjust belt tension by mobile motor at last, thereby realize the upper belt-wheel driving and can carry out tensioning, tuningout.

During use, fitting operation platform and ventilating dust-arrester are realized steel form impeller blasting automated job.
