Изобретение относитс к подъемно-транспортному машиностроению, в частности к грузоподъемным механизмам, используемым при подъемно-транспортных операци х, преимущественно при работе с механизированным инструментом.FIELD OF THE INVENTION The invention relates to a lifting and transport machinery, in particular, to lifting mechanisms used in lifting and transport operations, mainly when working with a power tool.

По основному авт. св. № 734138 известно устройство дл стопорени груза на канате , содержащее корпус, сквозь отверсти которого пропущен грузонесущий канат, расположенный между тормозными упорами и управл емым посредством гибкой т ги подпружиненным стопором, выполненным в виде установленного на оси двуплечего рычага , одним концом св занного с, гибкой т гой, а другим взаимодействующим с грузовым канатом, при этом отверсти дл грузонесущего каната расположены в корпусе соосно, а устройство снабжено серповидным стопором, верхним концом взаимодействующим с грузонесущим канатом и тормозным упором, соответствующим по форме верхнему концу серповидного стопора, а нижний конец серповидного стопора снабжен гибкой т гой, выведенной под углом к грузонесущему канату и снабженной подвеской дл груза, кроме того, в нижнем конце серповидного стопора выполнен канал, через который пропущен грузонесущий канат 1.According to the main author. St. No. 734138, there is a known device for stopping a load on a rope, comprising a housing, through the openings of which a load carrying rope is passed, located between the brake stops and controlled by a flexible rod, a spring-loaded stopper, made in the form of a two-arm mounted on the axis, connected to one end of the flexible the other, interacting with the cargo cable, with the holes for the load-carrying rope being coaxially located in the housing, and the device is equipped with a crescent-shaped stopper, the upper end of the interacting a load-carrying rope and a brake stop corresponding in shape to the upper end of the crescent stopper, and the lower end of the crescent-shaped stopper is provided with a flexible rod, bent at an angle to the carrying cable and equipped with a suspension for the load; besides, a channel through which is passed through cargo carrying rope 1.

Известное устройство имеет следующийThe known device has the following

5 недостаток при необходимости передвижени устройства с инструментом на значительную высоту, например, с одной высотой отметки на другую (в пределах междуэтажных перекрытий здани ), перевод серповидного стопо 0 ра из положени «Стоп в транспортное положение осуществл етс вручную. Это делаетс путем перестановки инструмента с карабина на крюк, разгружа таким образом серповидный стопор, а по заверщении передвижени инструмент вновь подвешивают на карабин.5 lack of the need to move the device with the tool to a considerable height, for example, from one elevation to another (within the building’s floor), transferring the crescent-shaped stop 0 from the "Stop to transport position" position manually. This is done by swapping the tool from the carabiner to the hook, thus unloading the crescent-shaped stopper, and when the movement is completed, the tool is again hung onto the carabiner.

Такого рода перестроповка (перестановка инструмента или иного груза с карабина на крюк и с крюка на карабин) создает неудобство и влечет за собой повыщение трудоемкости подъемно-транспортных операций.This kind of rearrangement (shifting a tool or other cargo from the carbine to the hook and from the hook to the carbine) creates inconvenience and entails an increase in the labor intensity of the lifting and transport operations.

Цель изобретени - снижение трудоемкости подъемно-транспортных операций.The purpose of the invention is to reduce the labor intensity of handling and transport operations.

Claims

This goal is achieved by the fact that the device is equipped with a mechanism for the self-installation of brake elements, including rotatable on an axis mounted on the side surface of the body, a sector with a helical working surface in contact with a crescent-shaped stopper, and the sector is connected by means of a rigid rod of adjustable length with a controlled stopper. FIG. 1 shows the device in the transport position; general form; in fig. 2 - the same, in the locked position. The proposed device contains a mechanism for self-installation of brake elements, consisting of rotating on axis 1 mounted on the side wall of housing 2, sector 3 with a spiral working surface in contact with a crescent-shaped stopper 4. Sector 3 is kinematically connected by adjustable rigid rod 5 with a shoulder 6 of a controlled stopper 7. Adjustable ta 5 of the mechanism for self-installation of brake elements are made with eyelets 8 having a screw connection to adjust its length. The shoulder 6 of the controlled stopper 7 and the console 9 of the sector 3 are hingedly connected to the thrust 5 and have limiters of the maximum angle of their rotation. The console 9 of sector 3, as well as the shoulder 6 of the controlled stopper 7, are distant from the axes I and 10 of rotation, which provides the possibility of their rotation relative to these axes with less effort on a flexible pipe 11 than the force of the weight of the load placed on the carbine 12. the limits of the housing 2 shoulder 6 and the console 9 can be closed protective cover (not shown). The device works as follows: The instrument lights up on the carbine 12 and it assumes the working position. If it is necessary to move the device from bottom to top or from top to bottom, a flexible pull 11 is used, with the help of which a mechanism is activated for setting the brake elements and the device as a whole takes the transport position (Fig. 1). With the release of the flexible rod 11, the mechanism for the self-installation of the brake elements is triggered and the device assumes a locked position (Fig. 2). Upon completion of the movement of the device with the tool up, the freeing lower end of the load carrying rope is rolled up into the coil and, to avoid interference (getting under the drill), is hung on hook 13. Using the invention will reduce the labor-intensive handling and, consequently, fatigue workers, which will positively affect on labor productivity. The invention The device for locking the load on the rope on the author. St. No. 734138, characterized in that, in order to reduce the labor intensity of lifting and transport operations, it is equipped with a mechanism for self-installation of brake elements, including a rotatable axis mounted on the side surface of the housing, a sector with a spiral working surface in contact with the crescent-shaped stopper, The mentioned sector is connected by means of a rigid pull of adjustable length to a controlled stopper.
