Description

Изобретение относитс к. строительству , а именно к подвижным элементам дл закрывани проемов.The invention relates to construction, in particular to movable elements for closing openings.

Известны вертикально-складные ворота, включающие две шарнирно соединенные створки, верхн из КОТОРЫХ установлена с возможностью поворота на горизонтальной оси и соединена с рычажной системой привода , а нижн створка снабжена роликами и св зана с противовесом 1}.Known vertically-folding gates, including two hinged doors, the upper of which are installed with the possibility of rotation on the horizontal axis and connected to the lever system of the drive, and the lower door is equipped with rollers and is connected to the counterweight 1}.

Недостатками известных ворот вл ютс сложность и громоздкость конструкции, за счет применени рычажной системы и кривошипно-шатунного механизма, что приводит к усложнению процесса открыти -закрыти ворот, повышению металлоемкости и трудоемкости монтажа конструкции ворот.The disadvantages of the known gates are the complexity and bulkiness of the design, due to the use of a lever system and a crank mechanism, which complicates the process of opening and closing the gate, increasing the metal consumption and laboriousness of mounting the gate structure.

Наиболее близкиг-ти к предлагаемым вл ютс подъемно-поворотные ворота, содержащие две шарнирно соединенные между собой створки, верхн из которых установлена шарнирно на балке проема ворот, а нижн св зана с противовесом и снабжена установленными на ос х опорными ооликами, оазмещенными в вертикальных направл ющих CToeKj и привел 2.Closest to the proposed are lifting and turning gates containing two hingedly interconnected shutters, the upper of which is hinged mounted on the beam of the door opening, and the lower one is connected to the counterweight and equipped with supporting oolics mounted on the axes in vertical directions CTeKj and led 2.

Недостатком известных во.рот вл етс сложность вывода их створок из вертикального положени , когда в начальный момент открывани ворот точка приложени открывающей силы находитс н-а одной пр мой с центром шарнира, соедин ющего створки. Причем во врем вывода ворот из распора возникают большие напр жени , A disadvantage of the known margins is the difficulty of withdrawing their flaps from a vertical position when, at the initial moment of opening the gate, the point of application of the opening force is n-a straight with the center of the hinge connecting the flaps. Moreover, during the withdrawal of the gate from the thrust there are large stresses

10 так как необходимо повернуть в начальный момент сразу обе створки, что может привести к срезу горизонтального вала и поломке муфт, вслед- . ствие чего ворота или не открывают15 с , или полуоткрытые створки с силой обруишваютс вниз. Все это обусловливает ненадежность ворот в эксплуатации- .10 as it is necessary to turn both doors at the initial moment at once, which can lead to the cutting off of the horizontal shaft and breakage of the sleeves, after-. The effect of which is that the gates either do not open for 15 seconds, or half-open sashes force downwards. All this causes the unreliability of the gate in operation-.

Цель изобретени - повышение на20 дежности .The purpose of the invention is to increase reliability.

Поставленна цель достигаетс тем, что в подъемно-поворотных воротах , содержащих две шарнирно соединенные между собой створки, верхн The goal is achieved by the fact that in a tilt and turn gate containing two hingedly connected sash,

Claims

25 of which are pivotally mounted on the beam of the gate opening, and the bottom one is attached to the weight and is equipped with roller bearings mounted on the axles. placed in vertical pressure racks, and the drive, on each axis a pusher rigidly mounted on each axis is made in the form of an L-shaped lever, the shoulders of which are connected to the drive by means of a chain transmission, and one of the arms is located along the guide. FIG. 1 shows schematically the construction of the gate; in fig. 2 gates in the closed position; in fig. 3 - the same, in the open position. The up-and-over door includes the upper 1 and lower 2 doors, interconnected by hinges. 3 The upper door 1 is installed with the help of hinges 4 on the upper horizontal beam 5 of the doorway. The lower flap 2 is connected to the side counterweights 6 by means of flexible t g 7 that are thrown over the blocks 8 rigidly mounted on the side gates 9 of the gate opening. Axes 10 are rigidly fixed on the lower valve ke 2, on which rollers 11 are mounted, placed in guides 12 made in lateral uprights 9. On axis 10, L-shaped levers 13 are mounted coaxially with rollers 11 to the ends of shoulders 14 and 15 the ends of the chains 16 interacting with the stars 17 mounted on the shaft 18 of the actuator 19 and with the sprockets 20 are fixed. The application point of the opening force is displaced relative to the center of the hinge 3 by the amount of the lever arm 13. The gate works as follows by chains 16 is transmitted to An epic force is applied to the end of the arm 14 of the lever 13, which creates a turning point on the lower flap 2, which brings the gate out of a state of tension. The rollers 11, moving along the guides 12, cause the lower flap 2 to rise upward and the upper flap 3 to rotate relative to the hinges 4 of the upper horizontal beam 5 of the gateway. When both doors are horizontal, the door is fully open. Claims of elevating and turning gates containing two hingedly interconnected sashes, the upper of which is hinged on the beam of the gate opening, and the lower is connected to the counterweight and equipped with axle-mounted support rollers placed in the vertical racks and the drive , characterized in that, in order to increase reliability, a pusher rigidly mounted on each axis is coaxially mounted on a roller, made in the form of an L-shaped lever, whose arms are connected to the drive by means of a chain transmission, and ev is disposed along the guide.
