(54) ПРИСПОСОБЛЕНИЕ ДЛЯ КРЕПЛЕНИЯ ПРОСЕИВАЮЩЕЙ ПОВЕРХНОСТИ, СОСТОЯЩЕЙ ИЗ СЕКЦИЙ(54) HARDWARE FOR FASTENING A SEATING SURFACE, CONTAINED FROM SECTIONS

II

Изобретение относитс к обогащению полезных ископаемых, а именно к классификации сыпучих материалов по крупности, на предпри ти х черной и цветной металлургии , а также в строительной промышленности , Наиболее эффективно может использоватьс в вибрационных грохотах дл креплени просеивающих поверхностей.The invention relates to the enrichment of minerals, namely the classification of bulk materials by size, in ferrous and nonferrous metallurgy, as well as in the construction industry. It can be used most effectively in vibrating screens for attaching screening surfaces.

Известно приспособление дл креплени просеивающей поверхности, состо щее из секций, включающее поперечные балочки, футерованные резиной. Концы секций просеивающей поверхности запрессованы в поперечные балочки 1.A device for fastening a screening surface, consisting of sections, including transverse beams lined with rubber is known. The ends of the sections of the screening surface are pressed into the cross beams 1.

Недостатком его вл етс то, что при необходимости замены одной из секций приходитс производить замену всей просеивающей поверхности.Its disadvantage is that, if it is necessary to replace one of the sections, it is necessary to replace the entire screening surface.

- Наиболее близким к изобретению по технической сущности вл етс приспособление дл креплени просеивающей поверхности , состо щей из секций, содержащее опорные продольные полосы, привареннь1е к поперечным трубам короба, на которые , укладываютс отдельные секции, соедин емые между собой стержн ми. Над полотном просеивающей поверхности в- The closest to the invention in its technical essence is a device for fastening a screening surface consisting of sections, comprising supporting longitudinal strips welded to the transverse pipes of the duct, on which separate sections are placed, interconnected by rods. Above the canvas screening surface in

месте стыка секций уложены вдоль продольных опор полось1, которые специальными скобами прижимают просеивающую поверхность к нижним опорам 2..the junction of the sections are laid along the longitudinal supports polos1, which with special brackets press the screening surface to the lower supports 2 ..

Недостатком этого приспособлени вл етс то, что замена секций вл етс трудоемкой операцией.The disadvantage of this device is that the replacement of sections is a time consuming operation.

Цель изобретени - ускорение и упрощение замены просеивающей поверхности.The purpose of the invention is to accelerate and simplify the replacement of the screening surface.

Поставленна цель достигаетс тем, что в приспособлении дл креплени просеивающей поверхности, включающем промежуточ10 ные опоры, закрепленные на св зь-балках, продольные полосы, уложенные на просеивающую поверхность в месте стыка секций и элементы фиксации, промежуточные опоры снабжены втулками с расшир ющимис книзу отверсти ми пр моугольного сечени The goal is achieved by the fact that in the fixture for fastening the screening surface, which includes intermediate supports fixed on the tie beams, longitudinal strips laid on the screening surface at the junction of the sections and fixing elements, intermediate supports are provided with sleeves with holes widening downwards rectangular section

Claims

15 and fixed inside them, and the fixing elements consist of V-shaped wedge rods installed inside the sleeve, with the curved ends of the rods located on top. In addition, in the 20 longitudinal stripes above the sleeves, holes are made, and the strips themselves are located under the curved ends of the wedge rods, in which grooves are made. FIG. I shows the proposed adaptation; in fig. 2, view A in FIG. one; in fig. 3- section BB in FIG. 2. The vibrating screen comprises a duct consisting of two bead blades 1, interconnected by coupling beams 2 made of pipes, longitudinal intermediate supports 3 with sleeves 4 welded thereto, having rectangular downwardly widening openings, screening surface 5, made in the form of a stamped or groove cards. The longitudinal intermediate supports 3 have along the axis a series of holes with a clamp equal to the pitch of the sleeves 4, in which spacer elements 6 are included, welded to the support 3 from below. 8, having special grooves to facilitate disassembly of the wedge joint. The assembly of the sections is as follows. Maps of the screening surface 5 are installed on the side and intermediate longitudinal supports 3 in such a way that the sleeves 4 are located between the screens. The strips 7 are mounted on top of the junction of the screens, and the wedge elements 8 are driven into the holes of the strips and sleeves 4. In this case, the spacer elements 6 bend the rods of the wedge elements and they occupy the position shown in FIG. 3. The bent rods of the wedge elements prevent the latter from falling out of the sleeves during the operation of the screen. Thus, reliable and fast fastening of the screening surfaces to the supporting elements was carried out. The joint is disassembled by means of a lever that is inserted into a special groove of the wedge element 8. The use of a device for fastening a screening surface consisting of sections will facilitate the replacement of sections and accelerate it, which, in turn, will affect performance. Claim 1. An attachment for fastening a screening surface consisting of sections, including intermediate supports mounted on a tie-beams, longitudinal strips laid on the screening surface at the junction of sections, and fixing elements, distinguished by the fact that accelerating and simplifying the replacement of sections of the screening surface, the intermediate supports are provided with bushings with downward-opening holes of rectangular cross-section and spacers fixed inside them, and the fixing elements consist of wedge rods braznoy shape, mounted inside the sleeve, wherein the bent ends of the rods are arranged on top. 2. Device according to claim 1, characterized in that the longitudinal strips have openings made above the sleeves and are located under the bent end of the wedge rods. 3. A device according to claim 1, characterized in that the bent ends of the wedge rods are grooved. Sources of information taken into account in the examination 1. Reference enrichment of ores.
