Abstract

The utility model discloses an abrasion resistant grilling frame for protection, and aims at overcoming defects that crisscross gratings of the existing cross-shaped grilling for the protection are arranged vertically, and the existing cross-shaped grilling for the protection is high in manufacture cost and affects normal production because an abrasion layer for bearing impacts is easy to fall off, quick in abrasion and is replaced frequently. Crisscross gratings which form cross-shaped grilling are welded inside the grilling frame formed by welding steel plates, and containing grooves are arranged at the upper portions of the crisscross gratings in the same direction. Because the containing grooves are arranged at the upper portions of the crisscross gratings in the same direction, when materials flow through the containing grooves from a high position, the containing grooves which face the materials and are impacted by the falling materials serve as receiving grooves for retaining the materials. After the materials are stacked in the containing grooves, a material-knockout-material state is formed, and the contact area between grilling parent metal and hard sundries flow is reduced, thereby reducing abrasion of the upper portions of the gratings, and improving the service life of the grilling frame, reducing manufacture cost, and guaranteeing the normal operation of the manufacture.

Description

The wear-resisting grills of protection

Technical field

The utility model belongs to protective device, and is specifically a kind of the transporting in the process of fragmentary goods, can stop the protective device of harmful foreign material damage equipment in the goods.

Background technology

Extracting fragmentary material from the stockyard, fall by funnel on the transmission belt of belt transporter, be transported to predetermined place by belt, is a kind of form that bulk goods is transported at mine, harbour etc.Because the goods source place difference in stockyard, usually can run into bulk goods and for example contain massive sharp-pointed stone, easy stifled foreign material etc. in the ore the inside.These massive foreign material are fallen on the belt of conveyer from higher position through funnel, and its deadweight adds impulsive force and often belt scratched or tears and cause damage, and not only frequently changing transmission belt influences normally carrying out of production again, has also increased productive costs simultaneously; Easily stifled foreign material often make funnel obstruction suitable for reading, and it is not smooth to cause fragmentary material to carry.

Being installed in the suitable for reading of funnel with grills, stopping from eminence to fall to the foreign material of funnel, is the mode that enterprises such as mine, harbour are commonly used to protect transmission belt.Present grills is to be welded into framework with steel plate, in the wall inboard of framework, is welded with the steel plate right-angled crossing bonded assembly cross grid of erectting, and adopts the build-up wear-resistant weldering again at its upper surface that is hit simultaneously, to have prolonged the service life of protective grille.When transporting the bulk goods that has foreign material, the foreign material that cross grid can intercept in the material pass through, and prevent from that bulk hard foreign material from dropping to cause on the transmission belt belt damage, can prevent that also foreign material from stopping up funnel.

But, because the right-angled crossing lattice plate of above-mentioned protective grille is straight up and down to arrange welding, it is very narrow that its upper surface bears the mill layer of hard foreign material impact, under the situation of frequently being impacted and rubbing, wearing layer is easy to come off, do not have the grid of wearing layer to be worn and scrap, changing grid has continually increased productive costs, has also influenced ordinary production.

The utility model content

Technical problem to be solved in the utility model is, overcoming existing protection straight up and down arranges with the right-angled crossing lattice plate of cross grid, its wearing layer that withstands shocks comes off easily, quick abrasion, the frequent replacing caused the productive costs height, influence the shortcoming of ordinary production, provide a kind of protection wear-resisting grills.

In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: in the framework with steel plate welding grills, be welded with the lattice plate of right-angled crossing, formation cross grid, be provided with tank on the lattice plate top of a direction of described right-angled crossing.

The utility model also has following technical characterictic:

Described tank is " V " font groove;

Lattice plate below described " V " font groove is for suitable " V " swash plate of word side plate diagonally extending, the bottom of swash plate, the wide end face that goes out the opposite side hang plate of " V " word on above-below direction;

The lattice plate of making right-angled crossing with the lattice plate of described being provided with " V " font groove is a vertical plate, and the height of " V " font groove is higher than vertical plate.

Advantage of the present utility model and good effect are, because the lattice plate top of a direction of cross grid is provided with tank, when material when eminence is flowed through tank, become the access slot of backgauge towards the tank that is subjected to material to scatter impact, material is piled up bulk cargo in groove after, form the state of material dnockout, reduced the area of contact of grid mother metal, reduced the wearing and tearing on plaid matching plate top with hard foreign material stream, thus the service life of having improved grills, reduce productive costs, guaranteed normally carrying out of production.

Description of drawings

Fig. 1 is a front view of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Among Fig. 1, in the framework 1 of the grills that welds with steel plate, right-angled crossing is welded with the lattice plate of forming cross grid 2, and the vertically disposed lattice plate top of cross grid 2 is provided with tank (referring to Fig. 2), and horizontal lattice plate is a vertical plate 3.During use, the material that falls earlier from eminence forms accumulation in tank, the material that the back falls is beaten on the material of piling up in tank, forms the state of material dnockout, reduced contacting of material and hard foreign material and cross grid 2 mother metals, also just reduced impact and wearing and tearing cross grid 2.

Among Fig. 2, pile up quickly in tank in order to make fragmentary material, earlier form the state of material dnockout, described tank is " V " font groove 2.1.

Further cushioned in order from described " V " font groove 2.1, to overflow the fragmentary material that comes, lattice plate below described " V " font groove 2.1, the swash plate 2.2 that forms for the right side board diagonally extending of " V " word, and the bottom that swash plate 2.2 tiltedly goes out, the end face of left side plate that exceeds " V " word on above-below direction is wide, after fragmentary material overflows from " V " font groove 2.1 and like this, can be slipped to along the bottom of swash plate 2.2 on the belt below the funnel, further reduce impact belt.

For the fragmentary material that eminence is fallen, more at first be deposited in " V " font groove 2.1, rather than at first or simultaneously beat on vertical plate 3, the height of described " V " font groove 2.1 is higher than vertical plate 3, like this, because " V " font groove 2.1 is suitable for reading outer spacious, can hide a part of end face of vertical plate 3, when the hard foreign material of bulk fall, may just bump less than the end face of vertical plate 3, thereby reduce collision or wearing and tearing vertical plate 3.
