Изобретение относитс к подъемным устройствам и .может быть использовано дл подъема створок ворот.The invention relates to lifting devices and can be used to lift the door leaves.

Известно устройство дл вращени барабана подъемных ворот, содержащее плиту и смонтированные на одной оси и взаимосв занные посредством упругой втулочнокольцевой муфты механизированный и ручной привода.A device for rotating a drum of a lifting gate is known, comprising a plate and mounted on the same axis and interconnected by means of an elastic sleeve-ring coupling, a mechanized and manual drive.

Недостатком данного устройства вл етс мала надежность в работе.The disadvantage of this device is low reliability in operation.

Цель изобретени - повышение надежности в работе устройства.The purpose of the invention is to increase the reliability of the device.

Указанна цель достигаетс тем, что оно имеет тормозной диск, рычаг с упорами, св занный с т гой, закрепленную на плите неподвижную планку с отверстием и размещенные на ней электромагнит, клин и тормозное кольцо и подвижную планку с-закрёп ленными на ней стержнем и поворотным диском с тормозным кольцом, при этом подвижна планка посредством щарнира смонтирована на неподвижной плите с возможностью взаимодействи с корем электромагнита , а стержень размещен в отверстии неподвижной планки и имеет пружину дл поджати планок, причем тормозной диск установлен на щпонках ступицы втулочно-пальцевой муфты между тормозными кольцами подвижной и неподвижной планок, а упоры рычага контактируют с клином неподвижной планки и подвижной планкой.This goal is achieved by the fact that it has a brake disc, a lever with stops, a fixed bar with an aperture fixed on the plate and an electromagnet placed on it, a wedge and a brake ring and a movable bar with a pin rotated on it. disc with a brake ring, while the movable plate by means of a hinge is mounted on a fixed plate with the ability to interact with the core of the electromagnet, and the rod is placed in the hole of the fixed plate and has a spring to press the bars, and the brake The disc is mounted on the pin of the hub of the sleeve-finger coupling between the brake rings of the movable and fixed strips, and the stops of the lever come into contact with the wedge of the fixed plank and the movable plank.

, - rope 4, including mounted on one axis and interconnected by means of elastic sleeve-ring coupling 5 through sleeve 6 with slot 7 of wheel 8 with fingers 9 of manual and mechanized drives with electric motor 10 and input shaft 11 of gearbox 12, whose output shaft is connected with shaft 2, brake disk 13, lever 14 with stops 15, connected with tension 16, fixed to the gearbox housing 12 fixed bar 17 with hole 18 and electromagnet 19 placed on it, wedge 20 and brake ring 21, movable bar 22 sec fixed to it by the rod 23 and the brake Ring 24, pivotally connected to the fixed bar axis 25, while the bark 26 of the electromagnet 19 is fixed to the movable bar 17, and the rod 23 is placed in the hole 18 of the fixed bar 17 and has a spring 27 to press the bars, and the brake disk 13 is mounted on a key 28 of the hub 29 of the pin-coupling 5 between the brake rings 21 and 24 of the movable 22 and the fixed 17 strips, and the anvil 15 of the lever 14 contacts the wedge 20 of the fixed stripe 17 and the movable stripe 22, besides the ha 16 connects to the sleeve 7 groove 5 by means of two shoulders lever 29 and has mortars 30 cooperating with a switch 31. The lever 32 has a spring 33. The device operates as follows. When you press the Up or Down button to raise or lower the door leaf, the electromagnet 19 is electrically powered, and the electromagnet's bark 26 moves to the right, thereby affecting the movable bar 22, which, turning about the axis 25, frees the brake disc 13 from interacting the brake rings 21 and 24 (Ferrado) with it, and at the same time the spring 27 is compressed, which, when the electromagnet 19 is turned on, provides electrical power to the electric motor 10 and transmits torque from it to the gearbox 12, second shaft is coupled to a shaft 2 which, while rotating, produces winding or coiling the rope 4 on the drum 1, thereby providing the lifting or lowering of the door leaf. The brake disc 13 at this moment rotates with the input shaft of the reducer, without hitting its side walls with the brake rings 21 and 24. When the supply of electrical power to the electromagnet 14 is stopped, its measles 26 moves to the left and under the force of the spring 27 the movable bar 22 rotates about axis 25, with This brake rings 21 and 24 interact with the brake disc pos. 19 and the input shaft of the gearbox is braked, which makes it possible to instantly stop the door curtain at any intermediate position. When the drive is operating, the switching mechanism acts on the rod 16, which, moving up, by the protrusion 30 presses the limit switch 31, which breaks the electric power supply circuit of the mechanized drive, and at the same time the fingers mounted on the fork of the double arm 24 act on the lateral surface of point 7 and the sleeves b with the wheel 8 are moved to the left relative to the fixed oyora, and the fingers 9 attached to the wheel 8 enter the holes of the elastic sleeve-to-pin coupling 5. When a circuit is affected, the torque is before a wheel 8 with the sleeve 6 and the pins 7, the wheels 9 are transmitted torque clutch 5. When this rotation is transmitted to the shaft 2 with rope drums 1 which are wound (unwound) cable, and there is lifting or lowering of the door leaf sections. In the case when the fingers 9 of the wheel 8 do not enter the holes of the clutch 5, and press into the body of the side surface of the clutch 5, then when turning the wheel 8 from the chain, when the fingers 9 are coaxial with the holes of the clutch 5, they will enter the holes by force spring 33, which in this case is inclusive. The use of the proposed device for rotating the lift gate drum will increase the reliability of its operation and simplify the design. In addition, both drives are operated independently. The invention of the device for - rotating the drum of the lifting gate, comprising a plate and mounted on one axis and interconnected by means of an elastic sleeve-finger coupling, mechanized and manual drive, characterized in that, in order to increase the reliability of the device in operation, it has a brake disc, a lever with lugs, connected with a bar, fixed plate on a plate with a hole and an electromagnet, a wedge and a brake ring placed on it, and a movable bar with a rod fixed on it and a turning disk with brake ring, while the movable plate by means of a hinge is mounted on a fixed plate with the possibility of interaction with the electromagnet core, and the rod is placed in the hole of the fixed plate and has a spring for pressing the planks, and the brake disc is mounted on the hub keys of the hub-to-pin coupling between the brake rings of the movable and fixed bar , and the levers of the lever are in contact with the wedge of the fixed pl-anka and the movable bar.
