(54) ВИНТОВОЙ СПУСК(54) SCREW DOWN

1one

Устройство относитс к транспортирующим средствам дл спуска сыпучих и штучных грузов под действием силы т жести и может найти применение в строительной, пищевой, горной и других област х народного хоз йства.The device relates to transporting means for launching bulk and piece goods under the action of gravity and can be used in construction, food, mining and other areas of the national economy.

Известен винтовой спуск, выполненный из смонтированнь х на опорах отдельных секций, снабженных футеровочными элементами , закрепленными на их внутренних поверхност х 1 .Known screw descent, made of mounted on the supports of individual sections, equipped with lining elements attached to their inner surfaces 1.

Недостатком такого спуска вл етс сложность как самой конструкции, так и ее изготовление. Дл придани несущей поверхности секци м, рабочей и опорной поверхности футеровочных элементов винтовой формы требуетс применение сложного и дорогосто щего прессового оборудовани . Применение болтовых соединений дл креплени футеровочных элементов еще более усложн ет конструкцию, так как требуегс сверление больщого количества отверстий как в секци х, так и в футеровочных элементах.The disadvantage of such a descent is the complexity of both the design itself and its manufacture. To impart a bearing surface to the sections, working and supporting surfaces of the lining elements of the helical form, the use of complex and expensive press equipment is required. The use of bolted joints to fasten the lining elements further complicates the design, since a large number of holes are required in both the sections and the lining elements.

Цель изобретени - упрощие конструкции .The purpose of the invention is simple designs.

Поставленна цель достигаетс тем, что секции выполнены в поперечном сечещ1и L-образными и соединены между собой L-образными ребрами, причем секции расположены со с.мещением но высоте относительно дру1а, а профиль каждого футеровочнэго элемента соответствует профилю ребра.The goal is achieved by the fact that the sections are made in the transverse section L-shaped and interconnected by L-shaped ribs, the sections being arranged with the height but relative to the other, and the profile of each lining element corresponds to the profile of the edge.

Предлагаемый винтовой спуск включает The proposed screw descent includes

10 расположенные по спирали плоские L-образные секции 1, поддерживающие опоры 2, ребра 3 и футеровочные элементы 4. Футеровочные элементы своими плоскими опорными поверхност ми 5 установлены на плоские секции 1. рабочие поверхности 6 футеровочных элементов расположены на уровне верхних кромок 7 ребер 3 и образуют винтовую поверхность.10 spiral-shaped flat L-shaped sections 1, supporting supports 2, ribs 3 and lining elements 4. The lining elements with their flat supporting surfaces 5 are mounted on flat sections 1. Working surfaces 6 of the lining elements are located at the level of the upper edges 7 of the edges 3 and form a helical surface.

Claims

20 sides are provided with a vertical fencing, formed by spiral flat flat sides 8, connected with each other ribs 3. By analogy with sections, the sides are protected from abrasive wear by means of lining elements 9 installed between the ribs, and the supporting surfaces of fi-fitting elements correspond profile board, and the workers are located at the level of the vertical edges of the 10 edges and form a helical surface. Options for screw screwing are possible with fencing having different angles of inclination to the horizon. The proposed screw snusk works as follows. The transported material enters the descent in its upper part, having a certain speed. Under the force of gravity, the transported material moves along the helical surface of the descent of the largest slope. The centrifugal force developed in this case prevents the material from descending from the screw surface towards its radial gradient. As a result, the transported material moves along a helical path in the direction of the lower discharge part of the removal. The proposed screw descent is simple to manufacture, as it consists of flat sections. Flat sections are connected by ribs, which gives the necessary rigidity. The lining elements are installed on the sections between the ribs, which ensures sufficient reliability of their fastening with, for example, cement mortar and does not require the use of bolts in the joint, it also simplifies the design. Making the bearing surfaces of the lining elements with flat plates makes it possible to manufacture the lining elements using a simplified technology to cast into open molds of cheap material, such as basalt melt. The location of the working surfaces of the lining elements at the level of the upper edges of the ribs and the formation of a helical surface by them makes it possible to obtain a smooth working surface of the screw cHvcKa without protrusions and edges. Claims of the invention: Screw descent, made of separate sections mounted on supports, equipped with lining elements, closed {) heat them on their inner surfaces x, characterized in that, in order to simplify the construction, the sections are made ji cross section L -shaped and interconnected L-shaped ribs, with the sections located with a shift in height relative to each other, and the profile of each lining element corresponds to the profile of the ribs.
